Plasma levels of circulating GH in adult (~30 weeks of age) female rats neonatally treated with MSG, MSG + GH, MSG + GRF or diluents (CONTROL) implanted with either rat GH or diluent containing osmotic mini pumps. Plasma levels of circulating GH were obtained from individual, undisturbed catheterized adult females for 7 continuous hours at 15 min intervals. Peritoneally implanted osmotic mini pumps were set to continuously deliver 15 μg of rat GH/kg bd wt / hr or just GH diluent in CONTROL rats. Similar results were obtained from 3 to 4 additional animals in each treatment group. See Materials and Methods for all treatment details. (Note different scales on the y-axes.)
