Dynamic tests and FSH biological activity in female rats with acute nephrotic syndrome.

To investigate the pituitary-ovarian status during the acute state of the nephrotic syndrome, a sequence of experiments were undertaken in adult female rats after a single dose of the puromycin aminonucleoside (PAN). The functional condition of the hypophyseal-ovarian unit was determined in control and nephrotic rats by two dynamic tests. In the first one, 10 days after PAN or placebo administration female rats were stimulated with LHRH (300 ng/100 g body wt) and samples were collected at 0, 20, 40, 60 and 80 min after releasing factor administration.
