Luteinization of Ovaries under Stressful Conditions in Persistent-Estrous Rats Bearing Hypothalamic Lesions

Adrenal Glands in Lactating Rats Bearing Hypothalamic Lesions.

It has been previously reported (Y o k o y am a and 0 t a, 1959a and b) that the lesions placed in the periventricular and the medial hypothalamic areas in lactating rats impaired oxytocin secretion selectively. Considerable amount of milk was obtained by oxytocin replacement in these rats, although the amount of milk was less than that obtained in normal lactating animals. There has been a con...

Stimulation of LH secretion in constant estrous rats under constant illumination by rat hypothalamic extract.

Adult female rats were rendered anovulatory by continuous illumination. Pituitary LH of these constant estrous rats decreased with the time length of illumination. Acidic extract from the rat hypothalamus was injected into these rats through the carotid artery for testing LH-RF activity. The extract, if a dose more than 2 hypothalamic fragments per rat was given, induced ovulation. Ovulatory re...

Studies on the mammary glands of lactating rats bearing hypothalamic lesions.

It has recently been shown, in experiments on lactating rats with hypothalamic lesions, that milk can be expressed from the mammary glands of rearing-failed, lesioned rats by weak palpation even 10 days after the operation when vigorous suckling by young continued, and that a considerable amount of milk is obtained from mammary glands of these lesioned rats by the regular administration of oxyt...
