The Dominance Pattern of Coronary Artery of Adult Bangladeshi People- A Postmortem Morphological Study.

Background: Incidence of the heart disease increases day by day in Bangladesh. Recent advances in cardiac surgery and the search for new techniques toward investigation of the heart are demanding a review of the anatomy of the coronary arteries. Method: The present study was performed on sixty (60) adult postmortem human hearts of Bangladeshi people. The samples were divided into 3 age groups: Group A (20 to 40 years) consists of 35 male & 7 female samples, Group B (41 to 60 years) consists of 3 female samples and Group C (61 to 75 years) consists of 7 male samples. Results: In the present study, dominance pattern of the coronary artery was right for male in-group A, B, C were 32 (91.4%), 7(87.5%), 6(85.7%), respectively and for female were 6 (85.7%). 3 (100%) respectively. It was left for male in-group A, B, C were 3 (8.6%), 1 (12.5%), 1(14.3%), respectively and for female was 1 (14.3%). Conclusion: The results of the present study can be helpful to the cardiologists and cardiovascular surgeons in the proper diagnosis and management of the heart diseases.

Studies on the bacterial flora of fish which are potential pathogens for human. Isolation of various potential human pathogenic organisms from different parts of fish and their significance in initiating human diseases.

Freshwater fish of different categories, collected from market of Dhaka City of Bangladesh, were studied for the bacterial flora. Potential human pathogens were isolated from about eighty-five percent of the fish studied. Organisms isolated were Aeromonas spp., (69.2%), Vibrio spp., (42.3%), Plesiomonas shigelloides (35.9%) and Escherichia coli (16.7%). The high association of potential human pathogens among the freshwater fish suggest that if fish are handled improperly or if consumed undercooked or uncooked may cause various diseases to susceptible individual.
