Histomorphometric study of thyroid gland of Bangladeshi people.

To study the histomorphological features of thyroid gland of Bangladeshi people in different age groups, thirty postmortem thyroid glands were collected and fixed in Bouin's fluid. For histological examination specimens were processed and stained following standard procedure and studied under low and high magnifications. Diameter of thyroid follicle and number of follicles per square millimeter were measured. Values were noted in a tabulated form and analyzed by SPSS program and findings were compared with the other studies of Western and Bangladeshi researchers and of standard textbooks. In this study it was observed that diameter of follicles were widely variable. The highest mean diameter of the follicles was found in 19 to 45 years age group and thyroids of this age group had fewer follicles per unit area of thyroid section than the two other groups. This difference was statistically significant with above 45 years age group (p=.001) and upto 18 years age group (p=.01) of the study. It was observed that all these findings of this geographical area were conformed to the findings of the other studies.
