Acute myocardial infarction (AMI) is a leading cause of morbidity and mortality worldwide. The incidence of AMI is dependent on certain traditional predisposing risk factors. In addition to the traditional risk factors, raised serum calcium level is also being considered as an associated factor for AMI. The aim of the study is to evaluate the association of serum calcium level with acute myocardial infarction in a tertiary level hospital in Bangladesh. This case control study was conducted in the Department of Biochemistry, Dhaka Medical College, Dhaka from January 2013 to December 2013. In this study, 50 diagnosed cases of AMI and 50 age and sex matched apparently healthy subjects were selected from DMCH purposively according to the selection criteria. Blood pressure, height and weight were measured and BMI was calculated. Biochemical parameters- serum calcium and fasting blood glucose in two groups were estimated in mmol/l. Then serum calcium was compared between two groups to observe the association with AMI. Results were analyzed statistically in SPSS version 17.0. Unpaired student's 't'-test and Spearman correlation analysis was done. All the results were expressed as mean ±SD and p value <0.05 was accepted as level of significance. Present study showed that serum calcium level was significantly higher(p=.001) in cases (2.61±.15 mmol/l) when compared with that of controls (2.13±.15mmol/l). Serum calcium also showed a significant positive correlation with AMI (rho=0.858, p=0.001).Findings of study concludes that increased serum calcium is associated with AMI.Bangladesh J Med Biochem 2015; 8(1): 16-20

An experiment was conducted to determine the impacts of fish population density on the growth and production of sarpunti (Barbonemus gonionotus), mrigal (Cirrhinus mrigala) and tilapia (Oreochromis niloticus) in polyculture system for a period of 90 days in six earthen pond .The experiment was carried out under three treatments each with two replications. The stocking density was 50 fish per decimal (sarpunti 20, mrigal 20 and tilapia 10) under treatment-I, 75 fish per decimal (sarpunti 30, mrigal 30 and tilapia 15) under treatment-II and 150 fish per decimal (sarpunti 60, mrigal 60 and tilapia 30) under treatment-III and all the ponds under three treatments supplementary feed was not used. The average initial length and weight of the fingerlings of sarpunti, mrigal and tilapia were 13.29 cm, 12.80 cm, 4.55cm and 22.7g, 23.75g and 3.84 g respectively. The ponds were fertilized fortnightly with cowdung, urea and TSP at the rates of 5 kg, 100 g and 200g per decimal, respectively. Mean survival rates of fish under treatment-I, treatment-II and treatment-III were 87.50%, 88.16% and 81.30% respectively. The specific growth rates (SGR, % per day) of fish under treatment-I, treatment-II and treatment-III were 1.13%, 1.03% and 0.80%. The calculated net fish production of the ponds under treatment-I was 1.61 ton/ha/yr and that of the ponds under treatment-II was 1.97 ton/ha/yr and 2.5 ton/ha/yr in treatment-III.

Acute ischemic stroke occurs more frequently in diabetic patients. The purpose of the present study was to observe the association of diabetes mellitus with acute ischemic stroke in Bangladeshi population. This case-control study was carried out in the Department of Biochemistry, Dhaka Medical College, Dhaka, Bangladesh during the period from January 2014 to December 2014. Patients presenting with acute ischemic stroke, age ranges from 18 to 65 years of both sexes, were taken as the case group. Age-and sex-matched healthy individuals were selected as control group. History of diabetes of both cases and controls were recorded and blood sample was collected from both cases and controls after overnight fasting for the estimation of blood sugar. A total number of 100 study subjects were taken of which 50 subjects presented with acute ischemic stroke were considered as cases and the rest 50 healthy subjects were taken as controls. In this study, the mean(±SD) of age of cases and controls were 56.54±12.18 and 53.34±7.98 years respectively. There was no statistically significant difference between mean age of the groups (p=0.124). Mean (±SD) of BMI was significantly higher in cases than that of controls (p=0.002) which were 27.25±3.25 and 25.38±2.57 respectively and the study subjects were sex matched, the difference between cases and controls was not statistically significant (p= 0.414). Diabetes mellitus was more commonly reported in case group (46.0%) than control group (6.0%) and the difference was found statistically significant (p=0.001). The risk estimation was calculated and was found a 13.34 OR (95% C.I. 3.66 to 48.62). From the findings of this study in may be concluded that diabetes mellitus is significantly associated with acute ischemic stroke.Bangladesh J Med Biochem 2016; 9(2): 45-48
