[Changes in the concentration of estradiol in the peripheral blood of immature female rats following intrahypothalamic administration of a factor liberating luteinizing hormone].
Administration of a synthetic luteinizing hormone-releasing factor (LH-RF) into the area of the medial eminence and the third ventricle of the sexually immature female rats, aged 20-22 days, caused a distinct increase in the estradiol concentration in the peripheral blood of the majority of these animals. Administration of physiological solution produced a reaction (much weaker) only in a small percentage of the animals. There was no increase in estradiol level when LH-RF got into the other areas of the hypothalamus.
