Abstract

Buserelin, a potent LH-RH agonist, has been used for the treatment of hormonal disorders such as precocious puberty, endometriosis, cystic mastitis and prostatic carcinoma. Prolonged treatment with buserelin has been known to induce a refractory phase of pituitary desensitization. In the present study, we found that two-week treatment with buserelin strongly suppressed the activities of thymidylate synthetase and thymidine kinase, and markedly reduced the appearance of BrdU-immunoreactive (S-phase) cells in both prostate glands and uteri in male and female adult rats, respectively.
