Abstract Background and Objectives: Ultrasonography is the most effective way to date pregnancy and to estimate the fetal weight in obstetric clinics. Currently, the diaphyseal length of humerus is used as a new parameter to estimate gestational age. The study evaluates the diaphyseal length of humerus as a parameter to estimate the gestational age of the fetus at the time of examination and to assess the growth pattern of humerus with advancing gestational age. Methods: The study was done on 152 antenatal women aged between 20 to 30 years of gestational ages from 15 to 40 weeks from the district of Dharwad, Karnataka, Subjects with maternal disease known to affect normal fetal growth wete excluded. The diaphyseal length of humerus was measured by radiologist in a standardized manner. The study describes the relationship of the diaphyseal length of humerus in centimeters, with the advancing gestational age in weeks. Results: It was observed that the diaphyseal length of humerus gradually increased from 15 weeks to 40 weeks of gestation and that the relationship is linear and direct. Normograms of diaphyseal lengths of humerus can be constructed by the formula derived by this study for this particular geographical area. Conclusion: The relationship between the diaphyseal length of humerus and the gestational age is linear and direct. The measurement of the diaphyseal lengths of humerus [in cm] can be an important additional parametet for estimating gestational age along with other parameters.

Introduction: Normal morphometric parameters of liver in human fetus were studied at various stage of development with an aim to get insight into the normal development of fetal liver. Material & Methods: Dissection of 29 human fetuses was performed. Anthropometric study was done and various parameters were measured. Results: The development of liver is associated with increase in all the parameters although the increase is highly variable in different gestational age, indicating that liver development showed characteristic but highly regulated development to reach its fully developed stage. Conclusion: The present study will be helpful in understanding the normal fetal liver development.

Abstract Background & Aim: The present study is aimed to document the histological changes of thymus gland during different weeks of gestation in human fetuses. Materials & methods: Fifty-three human fetuses (30 males and 23 females) of different age groups ranging from 9th to 40th gestational week were procured from the Department of Obstetrics and Gynaecology, Sree Balaji Medical College and Hospital, Chennai and from Mahathma Gandhi Medical College, Puducherry. The fetuses were dissected. The thymic tissues thus obtained were immersed in I 0% formalin for one week. After proper fixation, the tissue was subjected to routine processing and then the sections were stained with Haematoxylin and Eosin for microscopic examination. Results : Formation of lobules had started at 9th week and distinct formation of lobules was observed during the 12th week. The differentiation of the cortex and the medulla became well distinguished from the 14th week onwards. Presence of Hassall's Corpuscles was observed from 14th week and was found in all sections from 15th week onwards. Hassall's Corpuscles increased in number, size and maturity with the increase in the gestational age. Conclusion: Familiarity with the embryology, anatomy, and dynamic physiology of the thymus is essential for clinicians to avoid unnecessary imaging or invasive procedures.

Developed Surface

Intact otoconial membranes from 31 human fetuses ranging in gestational age from 14 to 36 weeks were studied. At all stages of development specimens from different individuals showed marked variations in overall shape. During the course of the second and third trimesters, both saccular and utricular otoconial membranes were found to increase three to fourfold in surface area and more than twofold in weight. Near the end of gestation the fetal specimens were about equal in area and weight to otoconial membranes from children up to 13 years of age. However, the crystal layers of the fetal membranes had less prominently developed surface contours than usually observed in children and adults, indicating that maturational changes continue after the time of birth.
