Association of Hypertension and Hypercholesterolemia in Patients with Type-2 Diabetes Mellitus.

The present cross-sectional analytical study was carried out to observe blood pressure and serum total cholesterol in patients with type-2 diabetes mellitus. This observational study was carried out in the department of Physiology, Mymensingh Medical College, Mymensingh, Bangladesh from January 2016 to December 2016. For this purpose, 200 subjects of both sexes and age ranged from 30-60 years were selected; among them 100 were type-2 diabetic person and 100 were apparently healthy. Blood pressure and serum total cholesterol was significantly higher (p<0.0001) in both male and female of the study group in comparison to healthy control group. From this study, it may conclude that type-2 persons are considered to have significant positive relation for formation of hypertension, hypercholesterolemia and metabolic abnormalities that have high morbidity and mortality. So, prevention of type-2 diabetes mellitus by taking necessary steps like regular physical exercise, intake of healthy diet and behavior therapy may help in prevention of type-2 diabetes mellitus related complication.

Physical training induced resting bradycardia and its association with cardiac autonomic nervous activities.

Regular physical exercise causes resting bradycardia. This exercise-induced resting bradycardia may be associated with exercise-induced changes in Cardiac autonomic nervous activities (CANA). Power Spectral Analysis (PSA) of Heart rate variability (HRV) is one of the most promising new techniques to quantify CANA. Regular physical exercise induced bradycardia is associated with exercise-induced adaptation in CANA. To observe the HRV parameters by frequency domain method (PSA), in male adolescent athletes in order to find out the influence of regular physical exercise on resting heart rate (HR) and CANA. The cross sectional study was carried out on 62 adolescent male athletes aged 12-18 years (group B), in the Department of Physiology, Bangabandhu Sheikh Mujib Medical University from 1st July 2007 to 30th June 2008. For comparison 30 age, sex and socioeconomic condition matched apparently healthy sedentary subjects (group A) were also studied. The study group was selected from the BKSP (Bangladesh Krira Shikka Prothistan, Savar, Dhaka) and the control from a residential school of Dhaka city. HRV parameters were assessed by Polygraph (Polyrite D, version 2.2). For statistical analysis Independent-Samples t-test was done as applicable. Resting mean HR was significantly (p<0.001) lower in the athletes. The mean value of Total (variance), VLF, LF and HF power was significantly (p<0.001) higher in athletes than that of non-athetes. Regular physical exercise-induced resting bradycardia is associated with exercise-induced adaptation in cardiac autonomic nervous activities.
