Superoxide Dismutase Activity in the Oviductal and Uterine Fluid of the Bitchand the Effects of the Enzyme on Viability, Motility and Hyperactivation of Canine SpermIn Vitro

[摘要] References(22)Cited-By(2)Superoxide dismutase (SOD) activity in flushings from oviducts and uterinehorns of 8 anestrous, 5 estrous and 7 diestrous bitches was measured. SOD activity inoviductal fluid in estrous bitches was significantly higher than that in anestrous anddiestrous bitches (P<0.01). SOD activity in uterine fluid of diestrousbitches was, however, significantly higher than that in anestrous and estrous bitches(P<0.01). Additionally, sperm collected from normal dogs wereincubated in MEM and in MEM containing SOD (SOD-MEM) for 24 hr. The percentages of spermwith viability, motility and hyperactivation in SOD-MEM were higher than those in MEM. SODproduced in oviduct and uterus may be able to maintain or improve sperm quality andfertility in the dog.
