Effects of Diabetogenic Agent Streptozotocin on Hematological Parameters of Wistar Albino Rats “An Experimental Study”

Background:Diabetes mellitus has remained the major concern for medical sciences researches duetoits deleterious effects on general, physical and mental health of patients. To understand the pathophysiology and to explore better treatment options for such kind of metabolic disorders it is necessary to generate the experimental animal models. To create diabetic animal models, streptozotocin has shown predominance in selectivity as a diabetogenic agent. While studying effects of any intervention in the diabetic animal models, being a cytotoxic drug streptozotocin may affect the study results by inhibiting highly replicating cells especially hematopoietic cells.Original ResearchArticle Aims:The aim of study was to analyze the effects of streptozotocin on various cellular components of blood such as RBCs, WBCs (Lymphocytes, Neutrophils, Eosinophils), Hb%, HCT and Platelets, at baseline,5thday and 15thday without any intervention.Study Design:Animal based Experimentalstudy.Place and duration of Study:The study was conducted at animal house of faculty of Pharmacy Ziauddin University Karachi, while laboratory work was performed at MDRL-1 Ziauddin University.Methodology:In Group A normal saline and in group B and C 60mg / kg streptozotocin diluted in normal saline was administered intraperitoneally. After the confirmation of induction of Diabetes in rats, on fifth day blood samples were drawn from Group A and B and were analyzed. While blood samples from group C weredrawn on fifteenth day.Results:Analysis of various hematological parameters on 5thday revealed that there was a decrease in the levels of Hb, HCT, RBCs and WBCs with an increase in platelet count in group B in comparison to group A (control). On the other hand, in Group C (15th day), blood cell counts (Hb, HCT, RBCs, WBCs, Lymphocytes, Neutrophils and platelets) seemed to recover from streptozotocin induced decline that was observed in group B, however did not reach the baselines as in group A(control).Conclusion:It is concluded that change in hematological parameters of rats after administration of streptozotocin is reversible. The blood parameters may recover near to base line values without any intervention within two weeks

Hemodynamic effects of contrast media and its adverse effects in Western Rajasthan: an observational study

Background: This study was aimed to investigate the hemodynamic effects of CT scan contrast media on pulse rate and blood pressure as well as identify the possible adverse drug reactions occurring after administration of contrast media.Methods: Information of patients such as age, sex, diagnosis, prescribed body part for CT scan, amount of contrast media and route of administration of contrast media were collected. Pulse and blood pressure were measured three times, before administration of iohexol or diatrizoate sodium; after 5 min and 1 hr administration of iohexol; after 1 hr and 2 hr starting of administration of diatrizoate sodium. ADR occurring after contrast media administration were observed.Results: Before Iohexol administration, SBP was 126.85±18.47 mmHg, which increased by 129.92±20.51 and 128.24±19.89 mmHg after 5 min. and 1 hr respectively after administration. Whereas before iohexol administration, DBP was 81.28±11.5 mm Hg, which was decreased by 80.58±13.03 and 78.90±13.15 mmHg after administration. The p-value for PR, pre-iohexol vs 1 hr post-iohexol was highly significant. Before Diatrizoate Sodium administration, SBP was 128.84±17.64 mmHg, that was decreased with 126.23±17.92 and 124.15±17.04 mmHg after administration. On the other hand, DBP was 81±11.99 mmHg which was decreased with 80.23±11.07 and 79.84±11.31 mmHg by Diatrizoate Sodium administration. P-value for SBP, DBP, and PR in various comparison of diatrizoate sodium administration was insignificant as well as total 18 ADRs were recorded post diatrizoate sodium and iohexol administration.Conclusions: Present study result demonstrates PR was significantly increased by administration of iohexol but not that much due to Diatrizoate Sodium especially after the 1 hr of iohexol administration. Although DBP decreased by both drugs, on the other hand, SBP increased by iohexol and decreased by Diatrizoate Sodium administration which was clinically insignificant. Although headache and giddiness were most common ADRs by both drugs.

Isolated bilateral zygomatic arch fracture; an unusal case

Zygomatic fractures are the most common facial fractures or second in frequency after the nasal fractures. The high incidence of zygomatic fractures probably relates to its prominent position in the facial skeleton hence it is frequently exposed to fractures. This case report presents an isolated bilateral zygomatic arch fracture that was been reduced by Gille's temporal approach and stabilized using foley's balloon catheter. This study highlights the importance of early diagnosis and timely treatment to reduce the morbities

Linkage study of DFNB3 responsible for hearing loss in human.

BACKGROUND: Hearing disorders represent a significant health problem worldwide. Recessive inherited cases of the deafness are more prevalent in Pakistan due to consanguineous marriages. Deafness caused by DFNB3 is due to mutation in the gene MYO XVA and its prevalence among Pakistani population is about 5%. MATERIALS AND METHODS: Families with at least two or more individual affected with deafness were selected from different areas of District Okara of Pakistan. Six consanguineous families of different ethnic groups having deaf individuals were studied. All these families had three or more deaf individuals in either two or more sib ships. Family history was taken to minimize the chances of other abnormalities. Pedigrees drawn by using Cyrillic software (version 2.1) showed that all the marriages were consanguineous and the families have recessive mode of inheritance. Three STR markers were selected and amplified on all the samples of six families through PCR. The PCR products were then genotyped on non denaturing polyacrylamide gel electrophoresis (PAGE). Haplotypes were constructed to determine the pattern of inheritance and also to determine whether a family was linked or unlinked with known DFNB3 locus. RESULTS: One out of six families showed linkage to the DFNB3 while rest of the families remained unlinked. Carriers of deafness genes were identified and information was provided to the families on request. CONCLUSION: Knowledge about the genetic causes of deafness provide insight into the variable expression of genes involved in this hereditary problem and may allow the prediction and prevention of associated health problems.

Lower incidence of nonsyndromic cleft lip with or without cleft palate in females: Is homocysteine a factor.

In India, as in other parts of the world, nonsyndromic cleft lip with or without cleft palate (NSCL±P) is a highly prevalent birth defect, its incidence in males being twice that in females. A case–control association study has been carried out with respect to homocysteine level and MTHFR C677T, A1298C and SLC19A1 (RFC1) G80A genotypes from an eastern Indian cohort to investigate whether Hcy and other Hcy-pathway genes also contribute to the risk level. While MTHFR 677T and SLC19A1 80G are individually and cumulatively risk factors, SLC19A1 80A appears to be protective against MTHFR 677T risk allele. Elevated Hcy associates with NSCL±P both in case mothers and cases. Significantly, this difference shows a gender bias: the level of elevation of Hcy in female cases is distinctly higher than in males, and more case females are hyperhomocyteinemic than the case males. It implies that compared with the males, higher level of Hcy is needed for NSCL±P to manifest in the females. We consider this as one of the possible factors why the incidence of this disorder in females is much lower than in males.

Etiology and pattern of swellings in mandible and maxilla

To determine the etiology and pattern of swellings in the mandible and maxilla. A descriptive study. This study was conducted at Oral and Maxillofacial Surgery Dept, Armed Forces Institute of Dentistry Rawalpindi for two years from December 2004 to December 2006. Three hundred and fifty patients with swellings in the jaws reporting to AFID were included in this study. After history, clinical examination and radiographic evaluation, patients were registered. All patients whether admitted to hospital or treated as outdoor patients in oral surgery clinic were included. Swelling of the parotid region, nasal and para nasal sinuses and neck were not included. In majority 131 [37.42%] the patients were of age between 21 to 30 years [mean 25.5 years]. Males were affected more than females with ratio 1.3:1. The most common swellings found were inflammatory which accounted for 138 cases [39.42%] due to odontogenic reasons i.e. caries and non vital teeth. The most frequent site involved was mandible which accounted for 202 cases [57.71%]. In 111 cases [31.71%] the treatment modality used was incision and drainage followed by antibiotics. Caries and non-vital teeth were cause of the most common inflammatory swellings. The predominant site of swellings was the mandible. Every person must visit a dentist for oral examination six monthly so that early lesions in mandible and maxilla can be detected and treated more conservatively

Oral cancer - are the dentists doing enough for its prevention and early diagnosis? - a study

The aim of this study was to determine whether and to what extent the dental profession is helping in the prevention and early diagnosis of oral cancers. Data were collected by distributing self administered questionnaires among two hundred randomly selected dentists of Rawalpindi and Islamabad to know what role they play in the prevention and early diagnosis of this deadly disease. More than half [52%] of the dentists did not ask or asked rarely about the use of tobacco, alcohol and other risk factors and only about a third [34%] advised and helped their patients to quit these habits. Only 22% of the dentists regularly examined the entire oral mucosa of all their patients and even fewer [12%] considered the possibility and then searched for a coincidental oral cancer. Only about 06% took biopsies of suspicious lesions regularly. The findings of this study indicate that the dentists of this region need to do a lot more for the prevention and early diagnosis of oral cancer
