Testicular cell population dynamics following palmitine hydroxide treatment in male dogs.
Palmitine hydroxide isolated from the roots of Berberis chitria administered orally to dogs 30 mg/kg per day for 60 days brings about a consistent impairment of primary and secondary spermatocytes and elongated spermatids (Stages IV-VIII). The primary and secondary spermatocytes were reduced by 60 and 68%, respectively, and the elongated spermatids were decreased by 58%. The number of spermatogonia and Sertoli cells remained unaltered. The production of immature and mature Leydig cells decreased by 66% and 27%, respectively. Protein, sialic acid and glycogen content and acid phosphatase activity of testes and epididymides were lowered to varying extents. Testicular cholesterol was elevated significantly. Weights of the testes and epididymides were significantly reduced. The antispermatogenic action of palmitine hydroxide may be mediated by disturbances in Leydig cell function.[1]References
