San Antonio, Texas 78284 Female rats at 25 days of age were left intact or rendered either blind, blind-pinealectomized.
blind-anosmic or blind-anosmic-pinealectomized. At 60 days of age blind-anosmic rats had depressed
body weights and markedly hypotrophic uteri, ovaries and adrenal glands. Pituitary LH levels were
significantly elevated in blind-anosmic rats whereas pituitary prolactin levels were significantly
depressed. Plasma LH levels in blind and blind-anosmic animals were significantly depressed: plasma
prolactin levels were unaffected by either of these treatments. Pinealectomy was effective in reversing
the effects of combined blinding and anosmia on body, reproductive organ and adrenal weights as well
as on pituitary LH and prolactin and plasma LH levels.
