Context: Anaemia is a common pregnancy related disorder in Bangladesh that causes various maternal and fetal problems. A prospective study was designed to see the associated maternal factors and fetal outcome in different categories of anaemia and to compare with that of normal pregnancy. Methods: The study was carried out on 60 Bangladeshi women within 35-40 weeks of gestation. Among them, 20 with normal uncomplicated pregnancies were considered as control group or group A, another 27 having pregnancies with mild anaemia were considered as group B, and 13 having pregnancies with moderate anaemia were considered as group C. Severe anaemic mothers were considered as group D, but 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 foetal outcome was observed and recorded after delivery.

Background: The position and size of isthmus of thyroid vary greatly in humans, and sometimes it is absent. The present study was designed to find out the difference in isthmus of the thyroid gland of Bangladeshi people in relation to age and sex. Methods: The cross-sectional, descriptive study was performed in the Department of Anatomy, Dhaka Medical College, Dhaka, from January to December 2008, on 73 post mortem human thyroid gland collected from unclaimed dead bodies. Isthmus was found in 60 cases. The samples having the isthmus (n=60) were divided into three age-groups including group A (10-20 years), group B (21-50 years) & group C (>50 years) and the isthmus was cut off from the thyroid gland, then its length, breadth and thickness were measured and recorded. Results: The isthmus of the thyroid gland was found in 82.2% cases. It extended from 2nd to 4th tracheal ring in 91.7% and from 2nd to 5th ring in 8.3% cases. No difference was found in length, breadth and thickness of the isthmus of the thyroid gland in between males and females. However, difference was found in breadth between group A & B (p<0.05) and A & C (p<0.01) and in thickness between group B & C (p<0.05). Conclusion: The presence or absence, positional change and variation in gross dimension of the thyroid isthmus were evident in humans. The morphological difference was found with increasing age but not with sex.

Context: The chick embryo is used as a research model in developmental biology. The present study was designed to see the difference in the somite number evolution during the early embryogenesis in two hen breeds i.e. Local (deshi) hen and Plymouth Rock hen and to achieve a more profound knowledge of avian embryology as well as correlate with human early development. Study design: Descriptive type of study. Place and period of study: Histology and Embryology Laboratory, Department of Anatomy, Dhaka Medical College, Dhaka, from July to December 2004. Materials & Methods: The experiment was carried out on embryos groups at the age of 24, 36, 48, and 72 hours of incubation for two individual hen breeds. For each incubation period, 10 samples were prepared in the laboratory and studied in each breed. The number of somite was observed under the light microscope with low power objective and recorded for individual sample. Obtained data was statistically processed in order to quantify the influence of the genetic variation. Results: The number of somite found in Local (deshi) hen and Plymouth Rock (broiler) hen after 24 hours of incubation were 1.02±0.34 and 0.86±0.65, after 36 hours 12.26±2.14 and 10.24±2.58, after 48 hours 21.34±2.57and 18.62±0.84, after 60 hours 32.14±2.31and 29.82±2.72 and after 72 hours 41.66±2.24 and 39.89±2.95 respectively.
