Ciliogenesis following salpingostomy of rabbit hydrosalpinges

Twenty-five artificially induced hydrosalpinges were studied in New Zealand white rabbits. Hydrosalpinges had been created after 2-16 wk occlusion of both the fimbrial end and the ampullary isthmic junction (A.I.J.), using either Ethilon 8/0 or tantalum clips. Their diameters ranged from 4 to 12 mm, being larger in the clipped oviducts. In hydrosalpinges larger than 6 mm diameter, a salpingostomy was done and ampullary biopsies were taken and prepared for scanning electron microscopy, and 1-micron sections and ultrathin sections for transmission electron microscopy. The changes observed were those found in previous work (Vásquez et al., 1981). Post-salpingostomy biopsies were taken from 10 patent oviducts at different intervals of time, ranging from 2 days to 8 wk. Ciliogenesis was observed between the 2nd and 3rd wk after salpingostomy.
