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.

In pregnancy, anaemia has a tremendous effect on the placenta. Maternal anaemia increases the volume of the placenta. Foetal hypoxaemia usually develops as a consequence of maternal anaemia, due to lower haemoglobin concentration, and stimulates placental growth. A prospective study was carried out in the Department of Obstetrics & Gynaecology, Dhaka Medical College Hospital and Maternal and Child Health Training Institute (widely known as Azimpur Maternity), Dhaka, Bangladesh, from August 2005 to June 2006 on 60 Bangladeshi women who were within 35-40 weeks of gestation. Among them, 20 had normal uncomplicated pregnancies (considered as control group or group A) and another 27 had pregnancies with mild anaemia (considered as group B1) and 13 had pregnancies with moderate anaemia (considered as group B2). Severe anaemic (considered as group B3) mother was not found during the period of collection of data for this study. The mothers were selected as who were suffering from antenatal anaemia i.e. having heamoglobin level <10 gm/dl (mild, if <10 gm/dl; moderate, if <8 gm/dl; and severe, if <6 gm/dl) and control i.e. having heamoglobin level ≥10 gm/dl. The placentae of the mothers were collected after delivery and their volume were measured by water displacement method and recorded. The present study showed that mean volume of placenta in group A, group B1 and group B2 were 444.00±38.37, 472.59±17.34 and 485.38±24.62 ml respectively. The difference between group A & B1, and A & B2 were found statistically significant. The volume of the placenta was found to increase with ascending grade of antenatal naemia of mothers in comparison to that of normal pregnancy.

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

A cross-sectional, descriptive type of study was designed to find out the difference in weight of the ovary of Bangladeshi women in relation to age and to compare with the previous studies. This study was done in the Department of Anatomy, Dhaka Medical College, Dhaka, from January to December 2009. The study was performed on 140 post mortem human ovaries collected from 70 unclaimed female 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 (10-13 years), group B (14-45 years) & group C (46-52 years) and the weight of the ovaries were measured and recorded. The difference in mean weight between the right ovary and the left ovary was statistically significant in all age group (P <0.001). The difference in mean weight of the ovary between group A & group B, group A & group C and group B & group C were statistically significant (P <0.001) DOI: http://dx.doi.org/10.3329/medtoday.v26i1.21304 Medicine Today 2014 Vol.26(1): 12-14
