RESUMO

In this current assessment, BaO synthesized from Moringa Oleifera leaves were irradiated using 0-75 kGy gamma radiation and investigated its physical impacts. The x-ray diffraction (XRD) data demonstrated the synthesis of tetragonal BaO, and no phase deviation was observed after irradiation. As doses are increased, the overall crystallite size were decreased due to an increase in defects and disorders. The tetragonal BaO was evident in Fourier transform infrared (FTIR) spectra prior to and following irradiation, while peak intensities and wavenumbers varied considerably. The as-prepared BaO showed a spherical shape morphology, and Field emission scanning electron microscopy (FESEM) indicated no vital deviations in it after irradiation. As irradiation shifts from 0 to 75 kGy, optical bandgap was increased from 4.55 to 4.93 eV, evaluated using Kubelka-Munk (K-M) equation from UV-vis-NIR spectrophotometer. Opto-electronic and photonic devices have challenges in extreme radiation conditions, such as space and nuclear environments. So, these assessments suggested that BaO can withstand high levels of gamma photon and could be a good option for photonic and optoelectronic instruments in an extreme gamma-ray exposed conditions.

RESUMO

Patients with chronic kidney disease (CKD) are more likely to have complications due to cardiovascular diseases (CVD). This cross sectional descriptive study was conducted in the Department of Medicine and Nephrology, Chittagong Medical College (CMC), Chittagong, Bangladesh from June to December, 2014 and was performed to estimate the risk of cardiovascular events according to Framingham's Risk Score of CKD patients. In this research, 100 patients who was diagnosed as CKD and admitted in the Chittagong Medical College Hospital were enrolled. Estimated glomerular filtration rate (eGFR) was calculated with the MDRD formula. Cardiovascular risk factors were analyzed by Framinghams criteria and after compilation data were analyzed by SPSS-18.0. Among 100 patients, most of patients were under 60 years of age where males (56.0%) were more than females (44.0%). Framingham Cardiovascular Risk Score revealed that most of the male were at high risk group compared to female. Regarding different components of lipid profile with Framingham risk score, higher risk group had high mean total cholesterol (212.17mg/dl) and also low mean HDL level (38.58mg/dl). Patient with different stages of CKD with cardiovascular risk showed stage 5 CKD was 80%, stage 4 was 15.0% and rest 5 was at stage 3 and most were in low risk group (56.0%). There were significant positive correlations found in between age and serum total cholesterol level with the cardiovascular risk scoring but not with HDL and eGFR. The predominant cardiovascular risk factors were age, male gender, smoking and high serum total cholesterol.

RESUMO

In the present study serum total cholesterol were estimated in chronic kidney diseased patient to observe the frequency of high serum total cholesterol in chronic kidney diseased patient (CKD) and to assess the incidence of hyper-cholesterolemia. This cross-sectional study was carried out in the department of Physiology of Mymensingh Medical College, Mymensingh from July 2014 to June 2015. For this purpose, total 200 subjects with age ranged from 25 to 60 years were selected and divided into 100 healthy persons as control group and 100 CKD patients as study group. Serum total cholesterol (TC) was evaluated by the Enzymatic, Liquid, Colorimetric test - CHOD/PAP method. Statistical analysis of data was done by unpaired student's t test. The results showed that serum total cholesterol the Mean±SE of control group male and study group male were 164±3.20mg/dl and 220±5.96mg/dl respectively. In study group male, mean±SE serum TC was increased. Result was statistically highly significant (p<0.0001). The Mean±SE serum TC of control group female and study group female were 158±3.13mg/dl and 213±5.49mg/dl respectively. In study group female, Mean±SE serum TC was increased & result was highly significant (p<0.0001). The mean serum total cholesterol level was increased in study group than in control group. The results were statistically significant. From this study, it may be concluded that the increasing frequency of Serum total cholesterol level in CKD may predispose the patients to hypercholesterolemia accelerates development of atherosclerosis, increases risk of cardiovascular disease (CVD) and the other complications.

RESUMO

Pneumonia is an acute on chronic infection involving the pulmonary parenchyma. Most cases are caused by microbial pathogens usually bacteria or viruses and less often fungi or parasites. Hyponatraemia on admission is associated with greater risk of death and increased length of hospital stays. Hyponatraemia is usually related to severe disease and specially occur in old aged people. This study is designed to identify proportion of hyponatraemia in patients with pneumonia and to determine the association of hyponatraemia with the severity of pneumonia. The cross sectional descriptive study was carried out at Mymensingh Medical College Hospital during the period of January 2018 to December 2018. Data were collected from purposively selected 73 admitted patients with pneumonia by interview, clinical examination and laboratory investigations using a pre-tested case record form. Data were analyzed by using SPSS version 20.0. Quantitative variables were summarized by mean and standard deviation. On the other hand qualitative variables were summarized by percentage. Necessary bivariate analysis was done. Majority (68.5%) of the patients were in the age group of 21 years to 50 years. Mean age of the patients was 41.9 years with a SD of 17.4 years. More than three fourth (57, 78.1%) were male and 16(21.9%) were female. More than two third (51, 69.9%) of the patients were smoker and 45(61.6%) was abuse of chewable tobacco or ghul. All the patients had fever (73, 100.0%); 70(95.9%) had cough, 50(68.5%) had chest pain, 10(13.5%) had respiratory distress and 8(11.0%) had haemoptysis. Vomiting was present in 9(12.3%) patients and 3(4.1%) had impaired level of consciousness. About one third of patients (32, 43.8%) had comorbidities. On chest X-ray consolidation was found in 59(80.8%) of patients with pneumonia. In 35(47.9%) patients serum Na⁺ level was normal and 38(52.1%) had different level of hyponatraemia; 26(35.6%) patients had mild hyponatraemia, 7(9.6%) had moderate hyponatraemia and 5(6.8%) had severe hyponatraemia. Majority (58, 79.5%) had lobar pneumonia and 71(97.3%) had community acquired pneumonia. Severity of pneumonia was assessed according to CURB 65. Less than half (35, 47.9%) of the patients had mild (score 0-1) pneumonia; 33(45.2%) had moderate (score 2) pneumonia and 5(6.8%) patients had severe (score ≥3) pneumonia. Average duration of hospital stay was 6.5±3.2 days. Maximum (69, 94.5%) patients were cured after treatment. In case of 3(4.1%) patients pneumonia was unresolved. One (1.4%) patients died due to pneumonia. In this study hyponatraemia was not associated with the severity of pneumonia (p>0.05) and outcome on discharge from the hospital (p>0.05). Difference in mean duration of hospital stay between patients of pneumonia with or without hyponatraemia was not significant (>0.05). The study results revealed that 52.1% patients with pneumonia developed different level of hyponatraemia. Hyponatraemia was not associated with the severity of pneumonia, duration of hospital stay and outcome of pneumonia.

RESUMO

Variety of conditions may be responsible for low back pain but lumber spinal canal stenosis is an important cause of low back pain. Lumber spinal canal stenosis usually presents with low backache with neurogenic claudication and shortness of walking distance in adult patient. Surgical management of lumbar spinal canal stenosis by decompression surgery is effective method. This prospective interventional study was performed in patient with clinical features like low back pain with radicular pain, neurogenic claudication, signs of root compression, positive MRI findings attending in department of Orthopaedic Surgery Mymensingh Medical College Hospital and Private Hospital from July 2016 to June 2019. Thirty patients were evaluated among those 20(66.6%) were 50 years and above. The mean age was 47.5±1.6 years. Male to female ratio was roughly 8:1. Almost all of the patients had low backache with radiation to the back of the thigh and leg with motor weakness (60%). About 66.6% of the patients had sensory deficit and 83.3% had neurogenic claudication. Majority (80.0%) of the patients at presentation had a suffering of 12 or >12 months. The mean duration of suffering was 14.7±5.1 months. About 55% of the patients were able to perform heel-walking and 36.0% tip-toe walking. Nearly 57% of the patients had sensory deficit along the distribution of 1st sacral nerve and 53.3% along the distribution of lumber 5 nerves. Diagnosis shows that 16.6% of patients had L4 lesion, 50% L5, 10.0% patients had L4 & L5 and 46.6% S1. Laminectomy was done in 26.6% of patients, laminectomy and disectomy in 33.3% and laminectomy, discectomy & foraminal decompression in 40.0% of patients. Twenty five (83.5%) of patients was free from symptoms. Eighty percent (80.0%) of patients shows minimal disability and 20.0% moderate disability on the basis of Oswestry Disability Index, while by MacNab criteria, most (80%) of patients was excellent, 10% good and another 10% fair. Repeated measure ANOVA statistics showed that mean Oswestry score decreased significantly from 54.5% at baseline to 22% at the end of 1 year (p<0.001).

RESUMO

A systematic review was conducted in early 2019 to evaluate the articles published that dealt with digital workflow, CAD, rapid prototyping and digital image processing in the rehabilitation by maxillofacial prosthetics. The objective of the review was to primarily identify the recorded cases of orofacial rehabilitation made by maxillofacial prosthetics using computer assisted 3D printing. Secondary objectives were to analyze the methods of data acquisition recorded with challenges and limitations documented with various software in the workflow. Articles were searched from Scopus, PubMed and Google Scholar based on the predetermined eligibility criteria. Thirty-nine selected papers from 1992 to 2019 were then read and categorized according to type of prosthesis described in the papers. For nasal prostheses, Common Methods of data acquisition mentioned were computed tomography, photogrammetry and laser scanners. After image processing, computer aided design (CAD) was used to design and merge the prosthesis to the peripheral healthy tissue. Designing and printing the mold was more preferred. Moisture and muscle movement affected the overall fit especially for prostheses directly designed and printed. For auricular prostheses, laser scanning was most preferred. For unilateral defects, CAD was used to mirror the healthy tissue over to the defect side. Authors emphasized on the need of digital library for prostheses selection, especially for bilateral defects. Printing the mold and conventionally creating the prosthesis was most preferred due to issues of proper fit and color matching. Orbital prostheses follow a similar workflow as auricular prosthesis. 3D photogrammetry and laser scans were more preferred and directly printing the prosthesis was favored in various instance. However, ocular prostheses fabrication was recorded to be a challenge due to difficulties in appropriate volume reconstruction and inability to mirror healthy globe. Only successful cases of digitally designed and printed iris were noted.

RESUMO

Since its inception in 1919, the Journal of Dental Research has continually published high-quality articles that span the breadth of research topics relevant to dentistry, oral surgery, and medicine. As part of the journal's centennial celebration, we conducted an electronic search on Scopus to identify and analyze the top 100 most cited articles from 1919 to 2018. Since Scopus does not capture older citations, we conducted an additional analysis by Google Scholar to identify key articles published in the first 50 y of the journal. Based on Scopus, the articles were ranked in descending order per their citation counts. The citation counts of the 100 most cited articles varied from 262 to 1,503. The year in which the largest number of top 100 articles were published was 2004 (n = 6). Within the top 100, the majority of articles originated from the United States (n = 52). Research Reports-Biomaterials & Bioengineering was the most frequent category of cited articles (n = 35). There was no significant association between total citation count and time since publication (correlation coefficient = -0.051, P = 0.656). However, there was a significant negative association of citation density (correlation coefficient = -0.610, P < 0.01) with time since publication. Our analyses demonstrate the broad reach of the journal and the dynamics in citation patterns and research agenda over its 100-y history. There is considerable evidence of the high variance in research output, when measured via citations, across the globe. Moreover, it remains unclear how patients' priorities and dental health care needs are aligned with the perceived influence of single research pieces identified by our search. Our findings may help to inspire future research in tackling these inequalities and highlight the need for conceptualizing research priorities.

RESUMO

Anterior cruciate ligament (ACL) is the most commonly injured ligament occurs in young adult population, which markedly reduces activity level. Anterior cruciate ligament rupture is a threat to the homeostasis of the knee. So, reconstruction of the ACL is necessary to make them fit and return to their pre-injury activity level. The choice of graft for ACL reconstruction is a matter of debate, with the BPTB graft and quadruple graft of ST-G being the two most popular options. Use of triplet graft of semi-tendinosus tendon alone without sacrificing gracilis is another option. So hypothesis was Arthroscopic ACL reconstruction with triplet autograft of semi-tendinosus tendon alone is an effective procedure. This prospective interventional study was conducted from October 2011 to March 2013 at Dhaka Medical College Hospital, Dhaka, Bangladesh. Fourteen patients who had a unilateral anterior cruciate ligament rupture underwent arthroscopic reconstruction with triplet graft of semi-tendinosus tendon. Accelerated ACL reconstruction rehabilitation protocol was followed and final outcome evaluation done at 24 weeks according to IKDC knee examination form and Lysholm knee scoring scale. Preoperative Lysholm knee score was 52.64 and postoperative score was 90, that shows significant improvement (p<0.05). According to Lysholm knee scoring scale, excellent results (95-100 points) were obtained in 33% patients, good results (85-94 points) in 53% patients, fair and poor (7% each). For arthroscopic ACL reconstruction, choice of semi-tendinosus tendon alone preserving gracilis, comparable outcome as with BPTB/ST-G graft, can be achieved, minimizing the hamstring strength deficit. Moreover gracilis being reserved for future use in revision ACL reconstruction and/or in other reconstructive surgery.

RESUMO

Acinar cell carcinoma (ACC) of the pancreas is a very rare neoplasm. We report a case of pancreatic acinar cell carcinoma involving the uncinate process of the pancreas. A 45 year old man presented with a painful upper abdominal mass without any jaundice or weight loss. Computed Tomography (CT) and Magnetic Resonance Cholangio-Pancreatography (MRCP) indicated a mass lesion in the uncinate process of the pancreas. He underwent Whipple's procedure (Pancreaticoduodenectomy). Histological slides revealed features of Acinar cell carcinoma (ACC) in the uncinate process of the pancreas and a lymph node.

RESUMO

The present cross-sectional study was conducted in the Department of Medicine, Mymensingh Medical College Hospital, Mymensingh from December 2009 to November 2010 to find out the association of iron deficiency, in anaemia with rheumatoid arthritis and to find a sensitive and less invasive marker to differentiate iron deficiency anaemia from the anaemia of chronic disease. A total of 45 patients of rheumatoid arthritis were provisionally included in the study. Of them, 12 patients were excluded as they did not allow for aspirating the bone marrow, leaving 33 patients to complete the study. The mean age of the patients was 42.6 years (22-66 years) with female to male ratio being roughly 3:1. Majority (97%) of the patients presented weakness followed by 78.8% dizziness, 54.5% palpitation, 24.2% pallor, 12.1% breathlessness, another 12.1% smooth tongue and 6.1% nail change. About 79% of the patients were positive for RA test and nearly 70% of patient had moderate anaemia. The mean serum ferritin was significantly reduced in patients with hypochromic with or without microcytic anaemia than that with normocytic normochromic anaemia (p<0.001). While total iron binding capacity was found to be significantly increased in patients with iron deficiency anaemia than that in patients with anaemia of chronic disease (p<0.021). The serum iron level was considerably reduced in the former group than that in the later group (p<0.066). Bone marrow iron grading revealed 48.5% of the patients with iron depleted and 51.5% with iron repleted. Serum ferritin level of patients with iron depleted bone marrow was significantly decreased than that in patients with iron repleted bone marrow (p<0.001). Serum iron level of the former group was also reduced than that of the later group (p<0.133). Total iron binding capacity was significantly raised in patients with iron depleted group than that in patients with iron repleted group (p<0.001). The study finds that anaemia of chronic disease and iron deficiency anaemia frequently coexist in patients with rheumatoid arthritis and serum ferritin and total iron binding capacity are considered good indicator for differentiating iron deficiency anaemia from the anaemia of chronic disease. Serum iron levels will not help for differentiating.

RESUMO

Carcinoma rectum is a challenging problem both for the developed and underdeveloped countries. Colorectal cancer accounts for 9% of all cancer deaths (49,920) in 2009 in USA. Carcinoma involving the lower part of the rectum is now successfully managed by sphincter saving surgery with less morbidity and uneventful recovery. To observe the objective, subjective and functional outcome of the patients suffering from cancer of the lower third of the rectum managed by surgical intervention with preservation of sphincter. A comparative study was carried out on 54 patients with low rectal cancer who underwent ultra-low anterior resection in the department of surgery, Bangabandhu Sheikh Mujib Medical University, Dhaka from January 2009 to December 2010. Patients were divided into two groups depending on the tumor distance from anal verge. Thirty one (57%) patients were in Group A (Experimental) where tumor distance was 5cm from anal verge and upper 1cm of anal sphincter was sacrificed during surgical intervention. Twenty three (43%) patients were in Group B (Control) where tumor distance was 6cm from anal verge and whole length (4cm) of anal sphincter was preserved during surgical intervention. Functional integrity of anal sphincter was assessed between these two groups of patients following surgery. The mean age of the patients was 45.96±14.41 years. During surgery, ultra low anterior resection was performed to remove the tumor in all patients and for anastomosis double stapling technique was performed in 52(96%) patients and hand sewn technique was performed in 2(4%) patients irrespective of tumor distance from anal verge. Covering ileostomy was fashioned in all but one patient. During post-operative follow up anal sphincter muscle tone, anal sphincter function (Anal continence, p = 0.54), Quality of life (Social life, p = 0.54; Professional life, p = 0.23; House work and Need a diaper, p = 0.54) were not significantly impaired in both groups. Functional outcome of anal sphincter muscle and quality of life was not impaired in comparison to general population after low rectal cancer surgery.

RESUMO

We have evaluated the craniofacial morphology of Japanese patients with unilateral cleft lip and palate (UCLP) and assessed the various postnatal factors that affect it. Lateral cephalograms of 140 subjects (mean (SD) aged 7 (2) years) with UCLP were taken before orthodontic treatment. Surgeons from Hokkaido University Hospital had done the primary operations. The craniofacial morphology was assessed by angular and linear cephalometric measurements. Cheiloplasty, palatoplasty, and preoperative orthopaedic treatment were chosen as postnatal factors. To compare the assessments of the postnatal factors, we made angular and linear cephalometric measurements for each subject and converted them into Z scores in relation to the mean (SD) of the two variables. Subjects treated by the modified Millard cheiloplasty had larger sella-nasion-point A (SNA) and nasion-point A-pogonion (NA-POG) measurements than subjects treated by the modified Millard with a vomer flap cheiloplasty. Two-stage palatoplasty showed consistently better craniofacial morphology than the other palatoplasty. Subjects who had preoperative orthopaedic treatment with a Hotz plate had significantly larger upper incisor/sella-nasion (U1-SN) measurements than who had no preoperative orthopaedic treatment or an active plate. We conclude that in subjects treated by a modified Millard type of cheiloplasty, a two-stage palatoplasty, and a Hotz plate there were fewer adverse effects on craniofacial morphology.

RESUMO

Consumption of pesticides associated foods increased in recent decades in Bangladesh. Most of the pesticides come from paddy, as rice is the main food items here and about 70 % pesticides are used only on paddy fields. Water samples of paddy fields and Kaliganga River of Manikganj district were analyzed to provide base line data on cypermethrin, chlorpyrifos and diazinon residue by using high performance liquid chromatography. Levels of Cypermethrin, chlorpyrifos and diazinon detected in the paddy field water samples were (0.605 ± 0.011 µg/L), (0.06 ± 0.001 µg/L) and (0.039 ± 0.002 µg/L), respectively. 0.11 ± 0.003 µg/L of cypermethrin and 0.012 ± 0.0006 µg/L of chlorpyrifos were also identified in the water samples of Kaligonga River. Diazinon residue was not detected in the river water samples. The detected concentrations of pesticide residues in the river water were below the accepted maximum residue limit (MRL) value of drinking water (0.1 µg/l) adopted by the FAO/WHO Codex Alimentarius Commission. Cypermethrin and chlorpyrifos were chosen for decontamination through rice bran, as it was found in river water. Two gm rice bran could easily decontaminated 95.6 % and 96.4 % of cypermethrin and chlorpyrifos. The result of this study showed that pesticide residue was detected in water samples were below the MRLs value, which can easily be decontaminated through absorption of rice bran.

RESUMO

Evaluating short-term (03 months) efficacy and safety of transurethral intraprostatic injection of absolute ethanol to treat benign prostatic hyperplasia (BPH). This intervention study was conducted to evaluate 30 patients with benign prostatic hyperplasia treated by transurethral injection of dehydrated ethanol. Mean age was 69.96 years. Endoscopic injection of 6-13.5 ml ethanol was carried out at 4-8 sites in the prostate. International Prostate Symptom Score (IPSS), maximum flow rate, prostate volume, postvoid residual and side effects or complications were measured postoperatively. Mean IPSS (SD) improved significantly from 18.43 ± 2.38 preoperatively to 6.80 ± 1.34 at 03 months of follow-up, mean peak urinary flow rate increased from 7.33 ± 1.19 ml/s to 16.31 ± 1.69 ml/s after 3 months, mean residual urine volume had decreased from 54.16 ± 30.93 ml to 17.01 ± 9.59 ml after 3 months (p<0.05). The prostate volume decreased from 44.66 ± 9.52 gm preoperatively to 32.46 ± 7.78 gm after 3 months (statistically significant at 5% level). There were no intra-operative complications but post-operative haematuria occurred in two patients, urinary retention occurred in two patients after removal of the catheter. Urinary tract infection developed in one patient. Transurethral ethanol ablation of prostate appears to be safe and cost effective. No occurrence of retrograde ejaculation was detected. The short-term effects of ethanol injection at prostate were satisfactory and acceptable as a minimally invasive therapeutic modality in selected patients.

RESUMO

The present descriptive cross-sectional study was conducted in the Department of Medicine, Mymensingh Medical College Hospital, Mymensingh, Bangladesh over a period of one year during November 2009 to October 2010. The study was conducted to describe the variations in types of stroke (ischemic stroke and hemorrhagic stroke) during summer and winter. An attempt was also made to observe the frequency of common risk factors of stroke by seasons. A total of 292 patients of any age irrespective of sex fulfilling the WHO criteria of acute stroke and confirmed by CT scan were selected from consecutive admission in the Department of Medicine, Mymensingh Medical College Hospital. Detail history and thorough clinical examinations were done. Routine and relevant investigations were carried out. The mean age of the patients was 59.9±14.3 years. A male preponderance was observed in the study. In summer 66% of patients and in winter 34% of patients were presented. Ischemic stroke was present in 54.1% patients and 45.9% patients had haemorrhagic stroke. The study found that the frequency of ischaemic stroke during summer (62.4%) was significantly greater than that during winter (37.8%). The frequency of haemorrhagic stroke during winter (62.2%) was significantly greater than that during summer (37.6%). Hypertension was the most important risk factor and other risk factors were smoking, diabetes mellitus, tobacco chewing, ischemic heart disease, dyslipidemia, oral contraceptive pill, alcohol consumption, atrial fibrillation and past history of stroke. Increasing age was also noted as a risk factor (60.7% >60 years). Most of the risk factors were homogenously distributed between two seasons and between ischemic and haemorrhagic group. Hypertension was significantly higher in haemorrhagic stroke patients compared to ischemic stroke patients.

RESUMO

The study was aimed to find out the correlation of serum triglyceride level with acute coronary syndrome. This cross sectional study was conducted in the department of cardiology, Mymensingh Medical College Hospital, from August 2009 to May 2010. Socio-demographic characteristics, smoking habit, hypertension, serum total cholesterol level, serum HDLc, Serum LDLc, TG level were important variable considered. A total number of 100 respondents consisted of 50 cases (patient) and 50 healthy persons (control). Investigations included ECG, cardiac enzyme (troponin I), FBS and lipid profile. The data were analyzed by computer with the help of SPSS. Chi-square Test, T-test & ANOVA test were used as test of significance. The mean level of TG in acute coronary syndrome (ACS) patients (cases) was 168.2±58.0 mg/dl and in control were 141.2±45.3 mg/dl. So serum TG level is significantly higher in patients with ACS (p=0.01). In multivariate regression analysis, there was a significant association of elevated TG with risk of ACS (relative risk) is the highest, compared with the lowest quarantile = 1.011; 95% confidence interval (CI = 1.002 - 1.020; P for trend = 0.01). The relation of TG level to HDLc was a strong predictor of ACS (RR in the highest) compared with lowest quarantile = 0.02; (95% CI = 0.003 - 0.173; P for trend <0.0001). The study revealed that high level of serum triglyceride is associated with ACS. Categorization of patients with ACS on the basis of TG level may be helpful for risk stratification and management.

RESUMO

Granular cell tumour (GCT) is a rare soft tissue neoplasm commonly encountered in the head and neck region, skin and subcutaneous tissue. GCT of the biliary system is most commonly reported in African-American females and usually presents as abdominal pain and obstructive jaundice. The neoplasm constitutes less than 10% of all benign tumours of the extra-hepatic biliary tree. No case of GCT involving the ampulla of Vater has been reported in the literature to date. We report a case of benign GCT involving the ampullary region in a 44-year-old Ethiopian male. Preoperative diagnosis was available on ERCP and deep biopsy. The patient was managed by debulking resection and biliary-enteric bypass and is symptom-free with no evidence of tumour progression after a follow-up of one year.

RESUMO

In the present study, we evaluated antimicrobial activity of clove oil against a range of fungal pathogens including that responsible for urogenital infection. Clove oil was found to possess strong antifungal activity against opportunistic fungal pathogens such as Candida albicans, Cryptococcus neoformans and Aspergillus fumigatus, etc. The oil was found to be extremely successful in the treatment of experimental murine vaginitis in model animals. On evaluating various formulations, topical administration of the liposomized clove oil was found to be most effective against treatment of vaginal candidiasis.

RESUMO

The human Burkitt lymphoma Ramos B cell line can be induced to undergo apoptosis in response to a variety of different agents, including calcium ionophores, anti-immunoglobulin (Ig) and macromolecular synthesis inhibitors. In addition, following up-regulation of the Fas (CD95) surface receptor by CD40 ligation, these cells also become susceptible to apoptosis induction by Fas ligation. We have previously shown that protection from calcium ionophore- and macromolecular synthesis inhibitor-induced apoptosis by CD40 ligation is associated with a rapid up-regulation of Bcl-xL followed by a more moderate and delayed up-regulation of Bcl-2. We show here that overexpression of Bcl-xL, like Bcl-2, protects Ramos cells from apoptosis induction in response to calcium ionophore, anti-Ig and macromolecular synthesis inhibition. However, in contrast to Bcl-2, ectopic overexpression of Bcl-xL does not rescue from Fas-mediated apoptosis. Thus, in Ramos B cells, the Fas apoptotic pathway exhibits differential sensitivity to inhibition by Bcl-2 family members. These findings also suggest that CD40 signaling provides a switch which renders the cells susceptible to Fas-ligand mediated apoptosis through up-regulation of Fas whilst affording protection from anti-Ig-induced apoptosis through up-regulation of Bcl-xL.
