The effect of inclusion of cerebrospinal fluid in the incubation medium on the in vitro secretion of luteinizing hormone from the bovine adenohypophysis.
Six in vitro trials were conducted using bovine tissues to study the effects of addition of cerebrospinal fluid (C.S.F.) to the incubation medium on the secretion of luteinizing hormone (LH) from adenohypophysial tissue, both in the presence and absence of hypothalami. Additionally, a study was made of the effect of including pineal bodies on the secretion of LH in both medium alone and in medium + C.S.F. No marked or consistent effect on LH secretion was observed when the C.S.F. concentration ranged between 5 per cent and 40 per cent, when the tissues were incubated in C.S.F. alone, nor when pineal bodies were added to the culture system. These results do not support the concept that the C.S.F. contains substantial amounts of substances which enhance secretion of LH from the anterior pituitary.
