ABSTRACT
The present study was carried out upon 2000 children aged from 5 to 12 years and were selected from different areas in Yemen. For each child, the body weight in Kg, height and head circumference in cm, were measured. These growth measurements were represented in tables and figures and compared with similar data of American and Egyptian children. The noted differences in growth measurements were attributed to genetic, nutritional, socioeconomic and environmental factors

This study was carried out on the cortex of the thymus gland of 5 adult rabbits. The thymic specimens were processed for light and electron microscopic examinations. Three epithelial cell types were recognized in the thymic cortex of adult rabbit and they showed evidences of secretory activity. These findings prove the heterogeneity of epithelial cells in the cortex of rabbit thymus and concluded that these cells continue to prepare T-lymphocytes in adult rabbits
