These radiations also deplete alkaline phosphatase which plays an important role in transport of material from sertoli cells to germinal cells and in the differentiation and proliferation of the germinal epithelium.
Six stained sections of each of the thirty animals were examined and 10 tubules from each of the sections were studied and observed, the diameters and germinal epithelium thickness (from the basal membrane towards the lumen of the tubule) were measured using anocular micrometer, and the meandiameter and germinal epithelial thickness were calculated.
The testes have germinal epithelium composed of two compartments: interstitial, formed by the connective tissue, blood vessels and Leydig cells, a thin peritubular cover of myoid cells and collagenous fibers surrounding the tubules; and germinal, formed by the tubules comprising germ cells (spermatogonia, primary and secondary spermatocytes and spermatozoa) and somatic cells (Sertoli) lying on a basement membrane (Fig.
30mm (Figure-3a), whereas the mean thickness of germinal epithelium was 85.
In the present study a significant increase in the thickness of the germinal epithelium was observed that likely cause of persistent follicles and subsequent ovulation and ovarian volume is another reason is the increase in size of the ovary and Sekoulareh and creates congestion and cortical vasculature [28].
Six-too-old animals showed initial development of germinal epithelium, whereas at 12 mo of age (SL, 30.
It is known that ethanol affects reproductive function in adult rats and that the deleterious effects are manifested as testicular atrophy, cellular damage in the germinal epithelium, reduced weight of the prostate, seminal vesicles and epididymis, as well as decreased sperm motility (ANDERSON JR.
These sections of heavily affected tubules looked dry, with a thinner peritoneum and a very circumvoluted germinal epithelium.
A few rows of metamorphosing spermatids remained in some seminiferous tubules but the germinal epithelium was exhausted.
As a result of the release of mature sperm from spermatocysts into the lobule lumina, the germinal epithelium becomes discontinuous (Fig.
Average germinal epithelium was thinnest in July 2001 and thickest in April 2001 and again in February and March of 2002.
