Sažetak
Numerous well known factors are responsible for the normal growth and skeletal development of human embryo and fetus. We tried to consolidate some of these factors in this study. The aim of the study was: a) to investigate the histomorphological differentiation and to asses the growth of parathyroid glands by histometric methods in human fetuses from the 2nd till 9th lunar months ; b) to compare the obtained histomorphologic and histometric results with the intensity of skeletal growth (diparietal head diameter and femoral length). Histomorphologic investigations were done by standard methods in serial sections of fetal parathyroid glands. The larger and shorter gland diameters were measured by ocular micrometer and the average diameter was calculated. All of the obtained diameter values were statistically evaluated. The fetal growth in normal pregnancies from the 3rd to 9th lunar months was investigated by ultrasound to defined normal fetal growth rhytm in a given population and in a given gestational period. The biparietal head diameter (BHD) and femoral length (FL) were measured and statistically evaluated. The average diameter values of parathyroid glands were compared with the values of the BHD and FL by test correlation matrix using biostatical program "Microstat". The correlation analysis demonstrated statistically significant correlation between all three investigates variables (P lower 0.01). Our histometric investigations have shown a gradual increase in the average diameter of parathyroid glands from lunar months 2 to 4. Then follows a sharp increased this value from lunar months 5 to 7. During lunar months 8 and 9 occurs its slight decrease. In this study, performed antrophometrical measurements of the head, femur and parathyroid glands speak for the concordance of the skeletal growth with the growth and differentiation of these glands.
