Background: The accessory pancreatic duct enters the duodenum at the minor duodenal papilla, developmentally draining the dorsal pancreatic bud; however, it is smaller and less constant than the main pancreatic duct and undergoes varying degrees of atrophy at the duodenal end. Objective: The objective of this study was to see the variations in course, opening and communication pattern of the accessory pancreatic duct in different age-groups in a Bangladeshi population. Methods: This crosssectional, descriptive study was done was done in the Department of Anatomy, Dhaka Medical College, Dhaka, from August 2005 to December 2006, based on collection and dissection of 75 postmortem male human pancreas. The collected samples were divided into seven age groups: 10-19 years, 20-29 years,30-39 years, 40-49 years, 50-59 years),60-69 years and(eˆ70 years. However, 65 samples were taken for final observation. Results: The accessory pancreatic duct was found in 27.69% specimens. Straight course was found in 50% specimen, while spindle course in 27.78% and cudgel course in 22.22% specimens were observed. In only 4 (6.15%) specimens, the accessory pancreatic duct communicates with the common bile duct, while in 11 (16.93%) specimens, the accessory pancreatic duct communicates with the main pancreatic duct. 12 (66.67%) accessory pancreatic ducts opened into the minor duodenal papilla, while 5 (27.78%) into the major duodenal papilla and 1 (5.55%) into the 3 rd duodenal papilla. Conclusion: Several variations were observed in accessory pancreatic duct pattern in terms of their course, opening and communications. However, no significant differences were evident in any parameter among the age groups. Here, females were excluded due to less availability of the female cadaveric pancreas during study period.

Background: The structural components of the thyroid gland are very much responsive to many types of stimuli and their adaptation is evident in histological studies. The thyroid follicles change their size and shape with the physiological alterations and pathological deviations. Objective: To observe the histological changes of the thyroid gland with advancing age in Bangladeshi people. Methods: This cross-sectional study was carried out in the Department of Anatomy, Dhaka Medical College, Dhaka from January to December 2008. The present study was performed on 60 post mortem human thyroid gland (39 of male and 21 of female) collected from unclaimed dead bodies which were in the morgue under examination in the Department of Forensic Medicine, Dhaka Medical College, Dhaka. The samples were divided into three age-groups including Group A (10 -20 years), Group B (21 -50 years) & Group C (> 50 years) and the glands were studied histologically including number and average diameter of the thyroid follicles, percentage proportion of the parenchyma and stroma. Results and conclusion: All the histological values of the thyroid gland studied i.e. number and average diameter of the thyroid follicles and percentage of the parenchyma, are found to increase with advancing age during the first 50 years of life and later decrease.

Context: A Cross-sectional, descriptive type of study was done in the Department of Anatomy, Dhaka Medical College, Dhaka, from July 2005 to June 2006, to see the variation in the size of the stomach with age in Bangladeshi people. Methods: The study was performed on 60 post mortem human stomach collected from unclaimed dead bodies which were in the morgue under examination in the Department of Forensic Medicine, Dhaka Medical College, Dhaka. The samples were divided into four age-groups including group A (2-16 years), group B (17-22 years) and group C (23-65 years). The length and breadth of each stomach were measured by using a measuring tape. Results: The mean length of the stomach were found 12.18±1.77 cm in group A, 17.74±1.95 cm in group B, and 25.31±1.63 cm in group C. The mean breadth of the stomach were found 6.81±0.40 cm, 8.26±0.57 cm and 9.54±0.45 cm in group A, B and C respectively. The differences between age groups were statistically significant (P<0.001). Conclusion: The length and breadth of the human stomach increase with age. DOI: http://dx.doi.org/10.3329/jdmc.v22i1.15598 J Dhaka Medical College, Vol. 22, No. 1, April, 2013, Page 16-18

Background:We proposed this study to see the difference in number and diameter of the islets of Langerhans of the pancreas with increasing age in Bangladeshi males, as male population is more prone to diabetes mellitus than female.
