Résumé

Presence of angiotensin converting enzyme (ACE, EC 3.4.15.1) in female reproductive tract and its interaction with semen has been investigated in domestic fowl. Higher activity of ACE was detected in homogenates of infundibulum region followed by magnum and relatively low level was noticed in rest of the parts of the oviduct (i.e. isthmus, uterus, uterovaginal-junction and vagina). This decreasing order in ACE activity was, however, reversed when these segments were incubated with semen. ACE in the ovarian follicular wall increased with corresponding increase in the follicle size. Presence of some stimulatory or inhibitory substances for ACE in the oviduct of fowl is suggested.

Résumé

Daily administration of cadmium salt for 25 days (2.5 mg per Kg body weight) in the male domestic fowl caused the end of treatment period. An increased incidences of concentration. Fertility dropped to zero at the end of the treatment period. Activity of acid and alkaline phosphomonoesterases were also drastically reduced by the end of treatment period. An increased incidences of morphological abnormalities of spermatozoa were noticed in the treated birds. After 46 days cessation of the treatment, full recovery of the above measures was found. These alterations suggest the reversible type of effect of cadmium chloride on the spermatozoa of male domestic fowl.
