The characteristic of the growth rates of various indicators at the stages of screening examination allows us to judge the adaptation processes occurring in the process of fetal growth. And in fetuses of pregnant women in a state of hypothyroidism, the intensity of growth of head parameters was less compared with the parameters of fetuses of healthy pregnant women. In fetuses of pregnant women in a state of hypothyroidism, the biparietal head size is significantly smaller at the stage of the second screening examination than in fetuses of healthy pregnant women.

The aim of our work is to identify features of morphogenesis in postnatal development, the study of the histological structure of different departments and membranes of rat heart at 1-22 days after birth. The object of the study was the heart of the 50 rats at 1, 6, 11, 16, 22 days after birth. Notes alternating periods of acceleration and deceleration of the growth rate increasing thickness of the atria and ventricles. Endocardial and epicardial thickness increases significantly less. The growth rate of the thickness of the ventricular myocardium were observed in rats 6 and 16 days of age. Structural changes occur due to the growth of the organism. Feature of the structure and topography of microvessels heart is their distribution in the course of cardiomyocytes and the relationship with fibrous connective tissue structures of cardiomyocytes.

Nowadays, the histological study of the kidney is gaining importance in medicine. In medicine and practice, diseases such as kidney stones, blood formation in the kidney - hematuria, glucose formation in the kidney - glucosuria, protein formation in the kidney - oliguria, and increased renal arterial blood pressure are increasing. Their treatment mainly focuses on the histological structure of the kidneys.

The article presents information on the morphobiological characteristics of the raw material plants distributed in the Fergana Valley and their protective phase.
