P-222: The Effect of Vitex Agnus Castus Essential Oil on Seminiferous Tubule Structure in Mice
Background: Plant materials continue to play an important role in the maintenance of human health since antiquity. Phytoestrogens are naturally occurring plant substances that can either mimic or antagonize the action of endogenous estrogens. This study was conducted to investigate the effects of vitex agnus as a phytoestrogenic plants, essential oil on structure and morphology of seminiferous ...
متن کاملThe arrangement of germ cells in the rat seminiferous tubule: an electron-microscope study.
The spermatogonia and early spermatocytes of 13 samples of rat seminiferous epithelium (about 0-05 mm2 each) were mapped from electron micrographs of serial sections. Clones of cells, connected by cytoplasmic bridges (syncytia of 2-100 cells), in various stages of spermatogenic development were identified. Maps of 7 separate areas are illustrated. It is concluded that, contrary to the models of...
متن کاملDouble-Stranded RNA-activated Protein Kinase, and Mx Proteins in the Rat Seminiferous Tubule
Although the involvement of viruses in alterations of testicular function and in sexually transmitted diseases is well known, paradoxically, the testicular antiviral defense system has virtually not been studied. The well known antiviral activity of interferons (IFNs) occurs via the action of several IFN-induced proteins, among which the 2 9 5 9 oligoadenylate synthetase (2 9 5 9 A synthetase),...
متن کاملReconstruction of Mouse Testicular Cellular Microenvironments in Long-Term Seminiferous Tubule Culture
Research on spermatogonia is hampered by complex architecture of the seminiferous tubule, poor viability of testicular tissue ex vivo and lack of physiologically relevant long-term culture systems. Therefore there is a need for an in vitro model that would enable long term survival and propagation of spermatogonia. We aimed at the most simplified approach to enable all different cell types with...
متن کاملMethotrexate levels in the interstitial space and seminiferous tubule of rat testis.
The ability of methotrexate (MTX) to pass from the blood into the interstitial space and seminiferous tubule of the rat was investigated using testicular micropuncture. MTX was administered to anesthetized adult Wister rats via a femoral vein cannula. Constant plasma levels of MTX were achieved by giving a priming dose followed by a constant infusion of 1, 10, or 100 mg/kg/hr with 6 to 27 rats ...
