Hematological and biochemical parameters during pregnancy were influenced by the pregnancy semester. Hematocrit showed large variations under the influence of the semester of pregnancy, semester II (32.04 ± 0.45) and semester III (40.57 ± 0.60). Glucose varied between (55.28 ± 0.83) in the first semester of pregnancy and (86.30 ± 2.19) in the third semester of pregnancy. Keywords: hematological, biochemical profile, woman, semester of pregnancy. 1. Introduction Blood is a liquid tissue composed of two major components, a liquid one, or plasma, and the other one represented by the cells suspended in plasma, the shaped elements. Unsaturated organic substances are carbohydrates and lipids and intermediates of their metabolism. Blood performs a number of functions that are vital to the body. By the blood the substances absorbed in the intestine are transported to all cells of the body, so it performs a nutritional function [6]. Nutrition is an important factor with significant influence on the health of pregnant women and the newborn [7]. * Corresponding author.

The hematocrit measures the ratio between the volume of erythrocytes and the total blood volume. Hematocrit is dependent on red blood cell count, mean red blood cell volume and plasma volume. Usually, when hematias are of normal size, the changes in hematocrit follow those of the erythrocytes [6, 8]. Vulnerability to illness is related to development disturbances and neonatal life. The regulation of development depends largely on maternal biochemical signals. All biochemical and metabolic signals serve to guide normal development [4, 5, 9]. The origin of the development of health and illness is a fundamental paradigm for the investigation and understanding of many metabolic diseases of modern humans [2, 3]. Environmental signals have the potential to change the developmental pathways of a young organism as a physiological result for adults and on Available online at http://journals.usamvcluj.ro/index.php/promediu ProEnvironment ProEnvironment 10 (2017) 282 - 285 282
