Synergistic impact of -linolenic acid and -tocopherol on in vitro maturation and culture of buffalo oocytes

Abstract The objective of the current study was to investigate the synergistic impact of -Tocopherol and -Linolenic acid (100 µM) on IVM and IVC of Nili Ravi buffalo oocytes. Oocytes were obtained from the ovaries of slaughtered buffaloes within two hours after slaughter and brought to laboratory. Buffalo cumulus oocyte complexes were placed randomly in the five experimental groups included; GROUP 1: Maturation media (MM) + 100 µM ALA (control), GROUP 2: MM + 100 µM ALA + 50M -Tocopherol, GROUP 3: MM + 100 µM ALA + 100M -Tocopherol, GROUP 4: MM + 100 µM ALA + 200 M -Tocopherol and GROUP 5: MM + 100 µM ALA + 300 M -Tocopherol under an atmosphere of 5% CO2 in air at 38.5 °C for 22-24 h. Cumulus expansion and nuclear maturation status was determined (Experiment 1). In experiment 2, oocytes were matured as in experiment 1. The matured oocytes were then fertilized in Tyrodes Albumin Lactate Pyruvate (TALP) medium for about 20 h and cultured in synthetic oviductal fluid (SOF) medium to determine effect of -Linolenic acid (100 µM) and -Tocopherol in IVM medium on IVC of presumptive zygotes. To study the effect of -Linolenic acid (100 µM) in IVM media and increasing concentration of -tocopherol in the culture media on early embryo development (Experiment 3), the presumptive zygotes were randomly distributed into the five experimental groups with increasing concentration of -tocopherol in culture media. Higher percentage of MII stage oocytes in experiment 1(65.2±2.0), embryos at morula stage in experiment 2 (30.4±1.5) and experiment 3 (22.2±2.0) were obtained. However, overall results for cumulus cell expansion, maturation of oocyte to MII stage and subsequent embryo development among treatments remain statistically similar (P > 0.05). Supplementation of -tocopherol in maturation media having -Linolenic acid and/or in embryo culture media did not further enhance in vitro maturation of oocyte or embryo production.

Resumo O objetivo do presente estudo foi investigar o impacto sinérgico do -tocoferol e do ácido -linolênico (100 µM) na MIV e CIV de oócitos de búfala Nili Ravi. Os oócitos foram obtidos dos ovários de búfalos abatidos duas horas após o abate e levados ao laboratório. Complexos de oócitos cumulus de búfalo foram colocados aleatoriamente nos cinco grupos experimentais incluídos; GRUPO 1: Meio de maturação (MM) + 100 µM ALA (controle), GRUPO 2: MM + 100 µM ALA + 50 µM -tocoferol, GRUPO 3: MM + 100 µM ALA + 100 µM -tocoferol, GRUPO 4: MM + 100 µM ALA + 200 M -tocoferol e GRUPO 5: MM + 100 µM ALA + 300 M -tocoferol sob uma atmosfera de 5% de CO2 em ar a 38,5 °C por 22-24 h. A expansão cumulus e o estado de maturação nuclear foram determinados (Experimento 1). No experimento 2, os oócitos foram maturados como no experimento 1. Os oócitos maturados foram então fertilizados em meio de Tyrode's Albumina Lactato Piruvato (TALP) por cerca de 20 h e cultivados em meio de fluido oviductal sintético (SOF) para determinar o efeito do ácido -linolênico (100 µM) e -tocoferol em meio IVM em IVC de presumíveis zigotos. Para estudar o efeito do ácido -linolênico (100 µM) em meio IVM e aumentar a concentração de -tocoferol no meio de cultura no desenvolvimento inicial do embrião (Experimento 3), os presumíveis zigotos foram distribuídos aleatoriamente nos cinco grupos experimentais com concentração crescente de -tocoferol em meios de cultura. Maior porcentagem de oócitos em estágio MII no experimento 1 (65,2 ± 2,0), embriões em estágio de mórula no experimento 2 (30,4 ± 1,5) e experimento 3 (22,2 ± 2,0) foram obtidos. No entanto, os resultados gerais para a expansão das células do cumulus, maturação do oócito para o estágio MII e desenvolvimento embrionário subsequente entre os tratamentos permanecem estatisticamente semelhantes (P> 0,05). A suplementação de -tocoferol em meios de maturação com ácido -linolênico e / ou em meios de cultura de embriões não aumentou ainda mais a maturação in vitro de oócitos ou a produção de embriões.

Study of Changes in Serum Copper Level in Patients with Acute Myocardial Infarction.

Acute myocardial infarction (AMI) commonly known as heart attack is defined pathologically as the irreversible death of myocardial cells caused by ischemia. Risk factors include high blood pressure, smoking, diabetes, lack of exercise, obesity, high blood cholesterol and excessive alcohol intake. The major cause of acute MI is coronary atherosclerosis with superimposed luminal thrombus, which accounts for more than 80% of all infarcts. Micronutrients and trace elements are very essential for normal functioning of the body. Even though they are required in very small amount, an alteration in the level of this element may lead to serious diseases like CAD and its consequences. The injury induced by reperfusion of the ischemic myocardium could result partially from the cytotoxic effects of oxygen free radicals. Copper is involved in several of the reactions in the protection from free radical damage. So, this study was designed to evaluate serum cupper level in AMI patients. This case-control study was conducted in the Department of Biochemistry, Mymensingh Medical College, Mymensingh, Bangladesh from July 2016 to June 2017. Total number of subjects was 120 in number. Among them 60 were diagnosed case of acute myocardial infarction and 60 were apparently healthy volunteers. Data were collected using pre-designed data collection sheets. After proper counseling informed written consent was taken from the study population. The study revealed that mean serum copper level was higher in case group as compared to control group. The mean±SD values of copper were 105.44±24.15µg/dl and 146.49±23.52µg/dl in control and case group respectively. The level of significance was 0.001 (p<0.05). After analyzing the results of the study it is concluded that serum copper level was significantly higher in Acute Myocardial Infarction patients than normal individuals. Therefore, estimation of serum copper level in AMI patients might be useful to take appropriate measure to prevent free radical induced reperfusion injury.

Risk Association, Clinical Presentation and Management of Uterine Leiomyoma.

Uterine leiomyoma is a common gynecological problem throughout the world. As 50% hysterectomies in black and 40% in Australians are performed due to fibroid, in our country also it is assumed that about 40%-50% hysterectomies are done due to fibroid uterus. Thus leiomyoma constitute a major public health cost to the community in terms of outpatient attendance and hospital cost for surgery. This is a descriptive type of cross sectional study among 50 patients having leiomyoma of uterus in the department of Obs and Gynae, BSMMU hospital from March 2011 to August 2011. The objective of the study is to find out the risk associated with leiomyoma, to find out the common presenting features of uterine leiomyoma and to find out best options for management. Study results showed that 62% patients were in the age group 36-45 years, 48%patients were in para1-2 group, 32% patients used combined oral contraceptive pill for contraception. Sixty percent (60%) patients presented with progressive menorrhagia and palpable mass was found in 62% cases. About 46% patients had associated medical conditions like hypertension, diabetes, obesity. Total abdominal hysterectomy was done in 32% cases. TAH with unilateral or bilateral salpingoophorectomy was done in 40% cases. Myomectomy was done in 20% cases. There is a scope for large scale study about risk factors of uterine leiomyoma like obesity, diabetes mellitus, hypertension, use of hormonal contraceptive, racial differences, different treatment modalities etc. Treatment should be individualized. However in this connection a good referral system and good communication has got a tremendous contribution in the proper management of such problems.

Effect of glutathione on pre and post-freezing sperm quality of Indian red jungle fowl (Gallus gallus murghi).

During cryopreservation sperm encounter oxidative stress due to higher production of ROS molecules and insufficient natural antioxidant defence system. Therefore, present study was designed to identify the effects of various glutathione (GSH) concentrations on Indian red jungle fowl (Gallus gallus murghi) sperm quality and fertility pre-freezing and post-thaw incubation hours. Semen was collected from eight cocks and qualified semen ejaculates having motility >65% were pooled after initial evaluation. Semen was divided in four aliquots, diluted with red fowl extender (1:5) at 37 °C having GSH 0 mM (control), 0.1 mM, 0.5 mM and 1.0 mM, cryopreserved and stored at (-196 °C) in liquid nitrogen. Semen quality was assessed at post dilution, cooling, equilibration, and freeze-thawing at 0, 2 and 4 h of incubation at 37 °C. Sperm motility, plasma membrane integrity, viability, acrosome integrity and mitochondrial function were recorded highest (P < 0.05) with 0.5 mM GSH in extender at post-dilution, cooling, equilibration, freeze-thawing and 0, 2 and 4 h of incubation. Lipid peroxidation in sperm and seminal plasma were recorded lowest (P < 0.05) with 0.5 mM GSH during cryopreservation stages and post-thawing incubation. Moreover, antioxidant activities (total antioxidant potential and free radical scavenging capacity) were recorded highest (P < 0.05) in extender having 0.5 mM GSH. Fertility rates were recorded higher (P < 0.05) with 0.5 mM GSH compared to control. It is concluded that 0.5 mM GSH in extender improves sperm structural (sperm viability, plasma membrane integrity and acrosome integrity), functional integrity (motility, mitochondrial function) and fertility parameters of Indian red jungle fowl through enriching antioxidant potential and ameliorating the oxidative stress.

Masculinization in common carp (Cyprinus carpio) by androgen immersion: The interaction effect of hormone concentration and immersion time / Masculinização na carpa comum (Cyprinus carpio) por imersão em androgênio: Efeito da interação da concentração hormonal e do tempo de imersão

Synthetic androgens (male hormones) administered to fish nursery are being used in aquaculture to avoid sexual differentiation and unwanted spawning at the eggs or the first feeding fry stage of fish. Present trial was conducted with the aim to produce male common carp (Cyprinus carpio) by egg immersion technique. Through this little insight, the effect of different hormone concentrations (17α-methyltestosterone @ HC:150, 300, 450 and 600 µgl-1) with immersion times (IT: 24, 48 and 72 hrs) and their interaction effect (HC x IT) on the hatching percentage of Cyprinus carpio eggs, percent survival and percent of male's production was evaluated specifically. Results showed that egg hatching percentage decreased with increased IT likewise, survival of treated fry was affected by increasing the IT (P<0.001). The main interaction effect of HC x IT showed that the highest percent of male individuals (95%) was obtained at 450-600 µgl-1 HC for 72 hrs IT, followed by 88-92.50% at 150-300 µgl-1 HC for 72-hrsof IT, 87.50% at 48-hrs of IT for rest of the hormone treatments, and lowest 47.50% was recorded in control (P<0.05). Increased percent male of Cyprinus carpio was obtained with increasing HC across all ITs. It was observed that the immersion treatment at 600µgl-1 for 72 hours was more effective to change the sex ratio of pre hatch Cyprinus carpio. A comparative outlook made from this experimental trial that sex induction of Cyprinus carpio by eggs immersion using synthetic male steroid hormone is an alternative safe technique of fish sex reversal in contrast to oral administration of hormone in fish feed.

Andrógenos sintéticos (hormônios masculinos) administrados ao viveiro de peixes estão sendo usados ​​na aquicultura para evitar a diferenciação sexual e a desova indesejada nos ovos ou no primeiro estágio de alimentação dos peixes. O presente estudo foi conduzido com o objetivo de produzir carpa comum masculina (Cyprinuscarpio) pela técnica de imersão em ovos. Com essa pequena percepção, o efeito de diferentes concentrações hormonais (17α-metiltestosterona @ HC: 150, 300, 450 e 600 µgl-1) com tempos de imersão (IT: 24, 48 e 72 horas) e seu efeito de interação (HC x IT) na porcentagem de eclosão dos ovos de Cyprinuscarpio, a porcentagem de sobrevivência e a porcentagem da produção masculina foram avaliadas especificamente. Os resultados mostraram que a porcentagem de incubação de ovos diminuiu com o aumento da TI da mesma forma, a sobrevivência dos alevinos tratados foi afetada pelo aumento da TI (P <0,001). O principal efeito de interação do HC x IT mostrou que o maior percentual de indivíduos do sexo masculino (95%) foi obtido com 450-600 µgl-1 HC por 72 horas de TI, seguido por 88-92,50% com 150-300 µgl-1 HC para 72 horas de TI, 87,50% às 48 horas de TI para o restante dos tratamentos hormonais, e 47,50% mais baixos foram registrados no controle (P <0,05). A porcentagem aumentada de macho de Cyprinuscarpio foi obtida com o aumento do HC em todas as TIs. Observou-se que o tratamento de imersão a 600µgl-1 por 72 horas foi mais efetivo na alteração da razão sexual do Cyprinuscarpio antes da eclosão. Uma perspectiva comparativa feita a partir deste ensaio experimental de que a indução sexual de Cyprinuscarpio por imersão de ovos usando hormônio esteróide masculino sintético é uma técnica alternativa segura de reversão do sexo em peixes, em contraste com a administração oral de hormônio na alimentação de peixes.

Effect of dimethylformamide on sperm quality and fertilizing ability of Indian red jungle fowl (Gallus gallus murghi).

The present study investigates the efficacy of dimehtlyformamide (DMF) as a permeable cryoprotectant and its effect on quality and fertility of Indian red jungle fowl sperm. Semen was collected from eight mature roosters, pooled, divided into five aliquots and diluted with red fowl extender having DMF (0%, 4%, 6%, 8% and 10%). Diluted semen samples were cooled from 37 °C to 4 °C, 20% glycerol added to control (0% DMF), equilibrated for 10 min and filled in 0.5 mL French straws, kept over liquid nitrogen vapors for 10 min and plunged into liquid nitrogen. Sperm motility, plasma membrane functionality, viability and acrosome integrity were assessed at post dilution, cooling, equilibration and freeze-thawing stage of cryopreservation. Cryopreservation stages had negative effects (P < 0.05) on semen quality parameters. Percentages of sperm motility, plasma membrane functionality, viability and acrosome integrity were recorded highest in extender having 8% DMF at post-dilution, cooling, equilibration and freeze-thawing stage. Fertility results after artificial insemination were recorded higher (P < 0.05) with 8% DMF compared to 20% glycerol. Dimehtlyformamide (8%) in red fowl extender improves the post thaw semen quality and fertility in Indian red jungle fowl and can be used effectively to avoid the contraceptive effects of glycerol.

Evaluation of Duodenal Eosinophil Count in Adult Patients with Functional Dyspepsia.

Several mechanisms have been proposed to explain the symptoms of functional dyspepsia but actual pathogenesis is still poorly understood. Recent studies support duodenal abnormality to be the most important causal link to explain symptoms and to understand abnormal pathophysiology of functional dyspepsia. The aim of this prospective observational study is to compare eosinophil count in duodenal mucosa between patients with functional dyspepsia and control subjects without dyspepsia and was done at the department of Gastroenterology, Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh from December 2015 to December 2016. Total 42 patients of functional dyspepsia based on Bangla validated version of ROME III criteria and 42 controls who were referred for upper gastrointestinal endoscopy for reasons other than dyspepsia were included. Biopsy specimens were collected from the second part (D2) of the duodenum of all participants. Eosinophil count was quantitatively evaluated by hematoxylin and eosin staining and expressed in numbers per 5 HPF. Significantly increased duodenal eosinophil count was found in functional dyspepsia group than non dyspeptic patients (22.78±08.78 vs. 14.90±10.70, p=0.001). Higher duodenal eosinophil count was found in patients with postprandial distress syndrome. Increased duodenal eosinophil count was found in patient of functional dyspepsia. It requires further large scale multicenter studies to establish duodenal eosinophilia as a biomarker of functional dyspepsia.

This retrospective study was done to see the clinical presentation and neuro imaging pattern of TSC in a tertiary care centre of Bangladesh and was conducted at Pediatric Neurology Unit of Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from January 2013 to December 2013. Among total 10 patients male-female ratio was 3:2. Commonest age group was 1-5 year in 50%. Common cutaneous abnormality was facial angiofibroma in 100%. Commonest neurological presentation was epilepsy in100%, ASD in 20% patient. Common renal manifestation was multicystic kidney disease (20%). CT/MRI findings were periventricular calcifications in 70% patients. In this study facial angiofibroma is the most common skin manifestation and epilepsy is the common neurological presentationandperiventricular calcification is the most common neuro-radiological findings in tuberous sclerosis complex.

Quality of life among women in Bangladesh following ileal conduit urinary diversion operations for irreparable vesicovaginal fistula and bladder exstrophy: observational study.

OBJECTIVE: To determine the quality of life (QOL) of fistula patients in Bangladesh who have undergone ileal conduit (IC) urinary diversion operations, and to assess whether the risks and ethical challenges involved, outweigh the reality of leaving a woman with urinary incontinence for the rest of her life. DESIGN: Observational study. SETTING: LAMB Hospital, Bangladesh. POPULATION: Seventeen women who had undergone IC between February 2012 and March 2016: 14 women previously had irreparable obstetric fistulas and three had bladder exstrophy. METHODS: Demographic, obstetric, IC-related, stigma and discrimination information were collected by questionnaire. Univariate analysis was done using the two-sided t-test for comparison of differences before and after IC surgery. MAIN OUTCOME METHODS: Change in stigma and discrimination scores. Health-related QOL assessed using the 36-item Short Form Health Survey. RESULTS: Of the 17 women, 14 (82.3%) felt they were cured of their fistula disease. Three complained of occasional leakage due to insufficient seal of the bag, mainly at night, and all but one experienced no limits to their daily activities. Stigma and discrimination scores were significantly lower after having the IC surgery. The mean difference from when the woman had a fistula to when she had an IC for stigma score was 3.17 (1.12-4.16, P < 0.001), and for discrimination score was 3 (1.9-4.1, P < 0.001). CONCLUSION: Overall, there has been improved QOL following IC among the women in this study and all would recommend IC to women in the same situation. They remain chronic patients with some physical symptoms, but are well re-integrated back into their communities. TWEETABLE ABSTRACT: Improved QOL following ileal conduit in women with persistent fistula related disorder in Bangladesh.

Association of Hypertension with Serum Estrogen Level in Postmenopausal Women.

Hypertension is a chronic and debilitating disease. Its complications give rise to cardiovascular diseases, stroke in Postmenopausal women. Estrogen deficiency that develops during menopause is likely the etiological factor for development of hypertension in postmenopausal women. Increased incidence of cardiovascular diseases in postmenopausal women may be due to hypertension caused by lower level of estrogen hormone. The study was carried out to observe the association of hypertension with serum estrogen level in postmenopausal women. This cross sectional study was conducted in the Department of Physiology, Dhaka Medical College, Dhaka, during the period of January 2011 to December 2011. A total number of 90 female subjects were selected from different areas of Dhaka city. Among them, 60 postmenopausal women with age ranging from 50 to 60 years were taken as study group and 30 apparently healthy premenopausal women with age ranging from 20 to 30 years were included as control group for comparison. Systolic blood pressure and diastolic blood pressure were recorded in both groups. Serum estrogen level was estimated in order to assess the hormonal level of both groups. Data was analyzed by Unpaired Student's 't' test and Pearson's co-efficient (r) test as applicable. The value of systolic blood pressure was higher in postmenopausal women than those of premenopausal women and result was statistically significant. The level of diastolic blood pressure was also significantly (p<0.001) higher in postmenopausal women in comparison to those of premenopausal women. In postmenopausal women serum estrogen level was lower than premenopausal women and serum estrogen level showed negative correlation with systolic and diastolic blood pressure levels. All these correlation were statistically non significant. Present study revealed that there is association of hypertension with serum estrogen level in postmenopausal women.

Evaluation of α-linolenic acid for freezability and in vivo fertility of Nili Ravi (Bubalus bubalis) buffalo semen.

Alpha linolenic acid (ALA) is integral component of cell membrane that protects the cell in stressful events and involves in many metabolic pathways. It was hypothesized that ALA have the ability to protect the structural and functional integrity of buffalo spermatozoa during freeze-thawing. Therefore, study was designed to evaluate ALA supplementation (0, 5, 10 and 20 ng/mL) in extender on freezability and in vivo fertility of buffalo bull spermatozoa. Semen from three adult Nili-Ravi buffalo bulls of similar age was collected with artificial vagina (42 °C) for five weeks (replicates; N = 30). Qualified semen ejaculates (>1 mL volume, >60% motility; >0.5 billion/mL concentration) were diluted with tris-citric acid extender containing 0.0 (control), 5.0, 10.0 and 20.0 ng/mL ALA at 37 °C and cryopreserved following established protocol. Sperm motility and plasma membrane integrity were recorded higher (P < 0.05) in extender containing 5.0 ng/mL of ALA compared to control. Nevertheless, sperm viability, live dead ratio and chromatin integrity were observed higher (P < 0.05) in all experimental extenders with ALA compared to control. The number of abnormal sperm reduced significantly in all experimental extenders having ALA. A total of 539 artificial inseminations were performed with the best evolved extender having ALA (5.0 ng/mL; 272 inseminations) and control (267 inseminations). In vivo fertility rates of buffalo semen were recorded higher (P < 0.05) with extender containing ALA (5.0 ng/mL) (58%) compared to control (46%). In conclusion, supplementing 5.0 ng/mL ALA in extender improved the post-thaw quality and in vivo fertility of cryopreserved Nili-Ravi buffalo bull semen.

Effect of season and age on Indian red jungle fowl (Gallus gallus murghi) semen characteristics: A 4-year retrospective study.

The reproductive potential of the adult males is expected to vary with age/season and largely differ not only in closely related avian species but even in subspecies, breeds and/or strains of the same species. Thus, it is pre-requisite to have knowledge of seminal parameters to achieve maximum production potential of at-risk species for ex situ in vitro conservation programs. A 4-year study was designed to evaluate the effect of age and season (spring, summer, autumn and winter) on semen characteristics of Indian red jungle fowl (Gallus gallus murghi) in a retrospective manner. Semen ejaculates (n = 1148) were regularly collected from eight adult cocks 6 to 54 months of age. Quantitative and qualitative semen parameters viz; volume (µL), concentration (1 × 109 mL-1), total sperm number per ejaculate (1 × 109 mL-1), motility (%), viability (%), plasma membrane integrity (%), acrosome integrity (%) and semen quality factor were recorded. A chronological increasing trend with age of most sperm quantitative and qualitative traits (semen volume, sperm concentration, total sperm number per ejaculate, plasma membrane integrity, viability, acrosomal integrity and semen quality factor) was observed. The highest values were observed at four years of age (P < 0.05) with the exception of sperm motility that was not affected by the age. Spring was the best season for sperm parameters viz; volume, motility, plasma membrane integrity, viability and acrosomal integrity (P < 0.05), however a remarkable sperm production was noticed all over the year. It is concluded that Indian red jungle fowl exhibits an evolution of sperm production that greatly differs in many points from other fowl sub-species. It is suggested that semen ejaculates of highest quality achieved for semen banking at the age of four year in the spring season.

Cryopreservation of Nili-Ravi buffalo (Bubalus bubalis) semen in AndroMed® extender; in vitro and in vivo evaluation.

The study was designed to evaluate AndroMed® for the freezability and fertility of Nili-Ravi buffalo semen. Semen was collected from four adult Nili-Ravi buffalo (Bubalus bubalis) bulls for 3 weeks (replicate). Semen ejaculates from each buffalo bull were divided into three aliquots. One aliquot was used for evaluation of motility, plasma membrane integrity, livability, viability, DNA integrity and normal apical ridge. Remaining two aliquots were diluted (37°C; 50 × 106 spermatozoa/ml) in tris-citric egg yolk or AndroMed® extender and cryopreserved in 0.5 ml French straws. After thawing, per cent post-thaw motility (47.9 ± 0.8, 49.2 ± 1.7), plasma membrane integrity (44.4 ± 1.2, 46.8 ± 1.8) and normal apical ridge (81.4 ± 0.3, 83.2 ± 0.3) were recorded similar (p > .05) in tris-citric egg yolk and AndroMed® extender. Higher (p < .05) percentage of sperm livability (70.5 ± 1.4 and 64.4 ± 1.0), viability (67.5 ± 1.5 and 61.5 ± 0.6) and DNA integrity (97.0 ± 0.3 and 93.4 ± 0.21) were recorded in AndroMed® compared to tris-citric egg yolk post-thaw. Values for all the aforementioned spermatozoal quality parameters were observed lower (p < .05) in frozen-thawed compared to fresh semen irrespective of the experimental extenders. Fertility rates of buffalo semen did not differ (p > .05) either cryopreserved in tris-citric egg yolk or AndroMed® extender (45.5% vs. 49%). It is concluded that AndroMed® is capable in protecting the buffalo bull sperm during freeze-thawing process and can be adopted safely for routine use replacing the tris-citric egg yolk extender in artificial insemination programme.

Abstract Synthetic androgens (male hormones) administered to fish nursery are being used in aquaculture to avoid sexual differentiation and unwanted spawning at the eggs or the first feeding fry stage of fish. Present trial was conducted with the aim to produce male common carp (Cyprinus carpio) by egg immersion technique. Through this little insight, the effect of different hormone concentrations (17-methyltestosterone @ HC:150, 300, 450 and 600 µgl-1) with immersion times (IT: 24, 48 and 72 hrs) and their interaction effect (HC x IT) on the hatching percentage of Cyprinus carpio eggs, percent survival and percent of males production was evaluated specifically. Results showed that egg hatching percentage decreased with increased IT likewise, survival of treated fry was affected by increasing the IT (P 0.001). The main interaction effect of HC x IT showed that the highest percent of male individuals (95%) was obtained at 450-600 µgl-1 HC for 72 hrs IT, followed by 88-92.50% at 150-300 µgl-1 HC for 72-hrsof IT, 87.50% at 48-hrs of IT for rest of the hormone treatments, and lowest 47.50% was recorded in control (P 0.05). Increased percent male of Cyprinus carpio was obtained with increasing HC across all ITs. It was observed that the immersion treatment at 600µgl-1 for 72 hours was more effective to change the sex ratio of pre hatch Cyprinus carpio. A comparative outlook made from this experimental trial that sex induction of Cyprinus carpio by eggs immersion using synthetic male steroid hormone is an alternative safe technique of fish sex reversal in contrast to oral administration of hormone in fish feed.

Association between Metabolic Syndrome and Acute Myocardial Infarction (AMI).

To evaluate the biochemical parameters of metabolic syndrome in case of acute myocardial infarction (AMI) patients this case control study was carried out in the department of Biochemistry, Mymensingh Medical College in collaboration with Department of Cardiology, Mymensingh Medical College Hospital, Mymensingh, Bangladesh from July 2012 to June 2013. To assess of serum total cholesterol, triacylglycerol, HDL-cholesterol, LDL-cholesterol, to estimate of serum glucose and to establish the association of age, sex, BMI, waist circumference, waist hip ratio and blood pressure of myocardial infarction patients. A total of 120 subjects were included in the study. Among them 60 were subjects of AMI cases and another 60 subjects of non AMI patients as controls. Serum total cholesterol, serum triacylglycerol, serum LDL-Cholesterol & serum HDL-Cholesterol were estimated in each sample. All values were expressed as Mean±SD. Statistical significance of difference between case and control were evaluated by using student's unpaired 't' test. All statistical analysis was done by using SPSS windows package. Past history of diabetes Mellitus and hypertension were more common in cases compared to those in control (p<0.001) which was statistically highly significant. There was no significant difference in the history of smoking between case and control. Statistical mean values of serum triacylglycerol, serum FBS, serum total cholesterol were highly significant in AMI patients in comparison to control (p<0.001). Statistical mean value of HDL-C was significantly decreased in AMI patients in contrast to control (p<0.001). In this study systolic blood pressure and diastolic blood pressure were significantly increased in AMI patients in comparison to control (p<0.05). Waist circumference was highly significant in AMI patients in comparison to control (p<0.001). Analyzing the findings of the present study there were significant alteration in lipid profile, blood pressure, fasting blood sugar & WC. These findings reaffirm the clinical importance of the metabolic syndrome as a significant risk factor for AMI. So it may be recommended that estimation of these parameters may help pivotal for better management of AMI.

Detection of Cervical Cancer through Visual Inspection of Cervix with Acetic Acid (VIA) and Colposcopy at Mymensingh Medical College Hospital.

Cervical cancer is the second most common cause of cancer related morbidity and mortality in women with 50% mortality rate. It is preventable if cervical cellular changes are detected and managed at early stage. This was a retrospective study conducted at VIA center of outpatient department and Colposcopy clinic at in-patient department of Mymensingh Medical College Hospital, Bangladesh covering a period from September 2013 to November 2014. Objective of this study was detection of cervical cancer and precancerous condition amongst patients reported to VIA center and Colposcopy clinic. In primary screening at VIA Center, total respondents were 3604, their mean age was 35.9 and highest were in the age group 31 to 40 years. At VIA center, 110(3.05%) were found positive and highest were between 31 to 40 years. In Colposcopy Clinic, out of 700 patients, 51.7% were CIN 1, 4.9% CIN 2, 1.4% CIN 3, invasive carcinoma was 0.3% and unsatisfactory or inconclusive were 34.3%. Most of the respondents were housewives and majority had poor monthly income. Amongst respondents, 72.1% were from rural area and Colposcopic findings revealed in 62.5% abnormal cervical changes, 46.5% were from rural area. Mean age at marriage or age at first coitus was found 16.25 years and 92.7% were in 11 to 20 years. Maximum abnormal cervical findings including CIN were between the ages ranged from 11 to 20 years of marriage age. In patients having 1 - 5 number of child having abnormal (58%) cervical changes, 48% were CIN 1. Histopathology reports found 19.6% CIN 1 (Total CIN 20.7%), cervical carcinoma 1.3%, inflammatory 7.0% and 0.42% cases were reported normal. Amongst 438 histopathology advised cases, 230 respondent's reports with patients were not available. VIA followed by Colposcopy has been a feasible, easy and reliable tools for screening cervical cancer in Bangladesh.

Histomorphological Study on Number of Acini of the Prostate Gland of Bangladeshi Cadaver.

The prostate is made up of 30 to 50 compound tubuloalveolar glands that are embedded in a framework of fibromuscular tissue and arranged in three concentric groups (mucosal, submucosal and main prostatic gland). The prostate consists of peripheral, central and transitional zone accounting for approximately 70%, 20% and 5% of the glandular substances. Benign prostatic hyperplasia affects the transitional zone and carcinoma of the prostate affects the peripheral zone. The glandular tissue consists of numerous acini with frequent internal papillae. Follicular epithelium is variable but predominantly columnar and either single-layered or pseudostratified. This cross sectional descriptive study was conducted in Department of Anatomy, Mymensingh Medical College, Mymensingh, Bangladesh to find out the difference in number of acini of the prostate gland of Bangladeshi people in relation to age. The present study was performed on 67 postmortem human prostate gland collected from the morgue in the Department of Forensic Medicine, Mymensingh Medical College by non random purposive sampling technique. The specimens were collected from Bangladeshi cadaver of age ranging from 10 to 80 years. All the specimens were grouped into three categories: Group A (up to 18 years), Group B (19 to 45 years) and Group C (above 45 years) according to age. Dissection was performed following standard autopsy techniques. In the present study, total 60 slides were made for histological study from both central and peripheral zone of the prostate which were examined under low power objectives. The number of the acini of the prostate gland were counted and recorded. The mean number of the acini of the prostate gland was 16.45, 43.54 and 42.45 in Group A, B and C respectively in central zone and 30.08, 51.35 and 44.16 in Group A, B and C respectively in peripheral zone of the prostate. Variance analysis shows that mean differences were highly significant between Group A & B and Group C & A and non significant between Group B & C in central zone of the prostate. Mean differences were non significant among all three groups in peripheral zone of the prostate. The number of the acini of prostate gland was increased up to certain age limit but decreased in extreme age. In statistical analysis, differences between age groups were analyzed by using students unpaired 't' test. The present study will help to increase the information pool on the number of the acini of the prostate gland of Bangladeshi people at different age group.

Cancer cervix: An uncommon malignancy in Kashmir, India.

OBJECTIVE: To study the distribution of cancers among females with particular emphasis on cancer cervix in Kashmiri population, which is geographically and socio-culturally distinct from the rest of India. MATERIALS AND METHODS: All patient records were screened from January 1, 2009 to December 31, 2011 at Regional Cancer Centre, Srinagar. Most common cancers among females were recorded and analysis of cancer cervix cases was performed. RESULTS: Female cancers comprised of 40% of total cancers with oesophageal and breast cancer as most common malignancies. Cancer cervix did not figure in top ten cancers and only 45 (0.01%) cases were recorded of the total of 3084 adult female cancers. CONCLUSION: We conclude that due to different socio-cultural and sexual practices, this cancer is highly uncommon in Kashmir and screening or possibly should be directed specifically at only high risk selective subjects.

Atypical post operative discharging sinus - a case report.

Surgical site infections (SSIs) are the second most common health care associated infection reported to the National Health Safety Network of the centre of disease control and prevention. SSIs by Mycobacterium tuberculosis are uncommon and diagnosis can be missed. Our patient had primary tuberculosis at surgical site without any evidence of tuberculosis at initial investigation. She presented with repeated discharging sinus at the wound of elective lower uterine caesarean section (LUCS). The case was diagnosed by histo-pathological evidence of chronic granulomatous lesion suggestive of tuberculosis from the excised tissue from wound and detection of acid fast bacilli (AFB) from swab by Ziehl Neelsen staining. After proper diagnosis the patient was treated with anti-tubercular drugs regiment for six months as per schedule of national guidelines for management of tuberculosis of Bangladesh Government. Then the patient was cured from unusual long sufferings.

Serum iron status among visceral leishmaniasis patients.

This case control cross sectional study was carried out in the Department of Biochemistry, Mymensingh Medical College, Bangladesh in cooperation with the Department of Microbiology, Medicine units of Mymensingh Medical College Hospital and Fulbaria & Muktagacha Upazilla Health Complexes, Mymensingh during the period of July 2006 - June 2007. The aim of the study was to explore the status of serum iron among visceral leishmaniasis patients in Bangladesh as a means to monitor the possibility of management of these patients. A total of 120 people of different age groups were included in this study. Subjects were divided into two groups - Group I (Control) consisting of 60 apparently healthy persons matched by age, sex and socioeconomic status with the cases and Group II (Case) consisting of 60 "ICT for Kala-azar" positive VL patients. Serum iron was estimated by colorimetric method with ferrozine from each sample. Statistical analysis was done by using SPSS windows package. Among the groups, mean±SD (Standard Deviation) of Group I and Group II serum iron were 100.67±20.83 and 76.76±8.64µgm/dl respectively. By comparing Group I with Group II highly significant difference were found in case of serum iron (P<0.001). It is evident from the study that serum iron level significantly decreases among visceral leishmaniasis patients in Bangladesh.
