| Abstract |
|
This experiment has been done to evaluate the relationship between the follicular atresia and the protein patterns on electrophoreais of the follicular fluids in porcine ovary. The protein concentration of the follicular fluids was lower than that of serum, and gradually decreased as the follicle siae became larger. The number of protein bands of follicular fluid on electrophoresis was less than that of serum, and gradually increased as follicle size became larger. Three specific bands were detected on disc PAGE and one band(M W. 75,000) on SDS PAGE in the follicular fluids, while not in serum. One band (A) at ${\beta}$-globulin region on disc PAGE became heavier, as follicles became atretic. Two bands less than(M. W. 20,000) were detected only in the large follicular fluid. Another band(M. W. 43,000) was not detected in necrotic group, whereas all other groups showed it. It could be concluded that the component and composition of the proteins follicular fluids changes according to the follicular size during atresia. Therefore detection of the changing pattern of proteins in the follicular fluid can be used as a basic criterion for the identification of follicular atretic stage. |
