Abstract:Background and Objectives: Pregnancy is the physiological process in which progressive anatomical, physiological and biochemical changes occur. Secretion of different hormones during pregnancy is responsible for maternal adaptation to the increasing demand of the growing fetus. The present study was aimed to evaluate serum calcium and phosphate status in normal pregnant women in different trimesters. Materials and Methods: A total number of 140 subjects, age range 20-40 (yrs) were recruited in the study which includes 100 normal pregnant women termed as study group (Group B) and 40 healthy women without pregnant (Group A), served as Control. Group B subjects were subdivided into Group B1 (n=12), Group B2 (n=30) and Group B3 (n=58) on the basis of duration of pregnancy-1st, 2nd and 3rd trimesters respectively. Calcium was measured by CPC (photometric method for Ca) and serum phosphate by colorimetric method. Statistical analysis was done using SPSS for Windows, Version 10. Unpaired Student's -'t' test performed to calculate statistical differences between groups. Results: Age (yrs) (mean±SD) and BMI of the pregnant women in different groups did not show statistical difference. Serum calcium (mean±SD) levels in the 1st (p=0.0001) and 2nd (p=0.02) trimester was significantly higher compared to the Controls. In 3rd the value was significantly lower (p=0.015) compared to the Controls and of 1st and 2nd trimesters (p=0.001). Serum phosphate (mean±SD) levels in three trimesters did not show statistical significant difference compared to the Controls and among the pregnancy groups. Conclusion: The data concluded that serum calcium level was lower during third trimester of the study subjects which may be explained by the fact of increased demand of the growing fetus and exposing the mother at risk of complications related to low serum calcium.

Background: Thyroid dysfunction especially hypothyroidism is cardiovascular risk factor because of its association with elevated serum total and LDL cholesterol. Objective: To assess the association of thyroid hormone levels with IHD. Methods: This cross-sectional study was carried out on 50 IHD subjects aged 35 to 85 years (Group B), in the Department of Physiology, Dhaka Medical College, Dhaka from of July 2009 to June 2010. For comparison 50 age, sex, and BMI matched apparently healthy subjects (Group-A) were also studied. The study subjects were selected from coronary care unit (CCU) of Cardiology Department & OPD of Dhaka Medical College Hospital, Dhaka. Serum FT3, FT4 and TSH were assessed by radio-immuno assay. Statistical analysis was done by student’s unpaired ‘t’ test and chi-square test as applicable. Result: The mean ±SD of serum FT3 and FT4 were significantly lower and serum TSH was significantly higher in IHD patients than that of healthy subjects (p<0.05). Conclusion: Hypothyroidism occurs in patients suffering from IHD. Key words: Thyroid hormone; IHD. DOI: http://dx.doi.org/10.3329/jbsp.v6i1.8080 J Bangladesh Soc Physiol. 2011 June; 6(1): 27-31

Background: In obesity insulin hypersecretion is a key feature indicating the abnormal pancreatic beta cell function which is the fundamental defect in the development of NIDDM, hypertension and cardiovascular diseases. Objective: To assess the secretory status of insulin in adult obese female. Methods: The present study was a cross sectional analytical study and conducted in the Department of Physiology, Dhaka Medical College, Dhaka from July 2012 to June 2013. 50 obese female subjects of 20-40 years were included from Out-patient Department (Obesity clinic) of BIRDEM Hospital, Dhaka and by personal contact from different areas of Dhaka city. 50 age matched, healthy non-obese female subjects selected as controls . Fasting serum insulin level was measured by ELISA and fasting glucose level was measured by Glucose oxidase method. The insulin secretory status was calculated by HOMA-%B using HOMA software. For statistical analysis unpaired Student's 't' test and Pearson's correlation coefficient (r) test were performed as applicable . Result: Mean fasting serum insulin and HOMA%B (P<0.001) were higher in the obese than that non obese. Fasting serum insulin level and HOMA%B showed significantly positive correlation with WHR. Conclusion: This study concludes that obese individual develops a state of insulin hypersecretion and hyperinsulinemia.

Since the early 1970s. calcium phosphate (Ca-P) index has been regarded as a risk factor for extra skeletal calcification. tumoral calcinosis and increased cardiovascular event and death. The general consensus was not to exceed 70 ing2h1Lt (5.6 unno1/1,2) in chronic kidney disease. The present study was done to find out the Ca - P index in different stages of (CKB) patients to assess the risks of the patients which can be understood and be negotiated. In this study 100 of previously diagnosed chronic kidney disease patients of different stages as CKD stage Ill. IV and stage V were included. Subjects were divided into three groups according to staging of chronic kidney disease : group A (stage 111) were 34 patients, group 8 (Stage IV) were 36 and group C (Stage V) were 30 patients. Mean serum inorganic phosphate level was in group A .5.41 + 2.49. group 8 8.17 + 3.63 and in group C 10.50 + 3.06. Mean serum Calcium level in three groups were in group-A 8.36± 0.74. group- B 8.10± 0.75 and in group- C was 7.43± 1.27 ). Ca - P index was calculated by multiplying the serum calcium and phosphate level. Mean Ca-P index was in group-A 49.39+ 22.95. group B-67.93+ 31.2 and in group-C 90.76+ 24.82. Statistical analysis was done betWeen these groups and it was signifimuly higher in group B than group A ( p< 0.06. group A is group 8). in group C than group A ( p< 0.00. group A vs group C) and in ,group C than group ft ( p< .002. group B vs group C). It was found that as the renal function deteriorates gradually the Ca P index increases and it is highly significantly higher in CKD — V patient than other stages.
