Alanine transport across in vitro rabbit vagina.
Transmural flux of alanine across the vaginal epithelium of the rabbit is a specialized mechanism. There is a net serosal to mucosal translocation of the amino acid in the absence of a concentration gradient. Changes in reproductive cycle do not influence this mechanism but, in castrated animals, it is abolished. Transport properties of vaginal epithelium is important because of increasing utilization of intravaginal contraceptives.
