Hypophysectomized Rats

Different methods for administration of human growth hormone (hGH) have been examined with a view to efficient use of the limited amounts of hGH at present available for clinical use. We found that in hypophysectomized rats (1) hGH administered by continuous subcutaneous infusion induced a greater increase in body weight (referred to throughout as growth) than hGH administered by intermittent (daily) injection and (2) intermittent injections of hGH dissolved in 16% gelatin induced more growth than hGH dissolved in a glycine buffer. It was further found that (1) hGH dissolved in 16% gelatin compared with hGH dissolved in a glycine buffer induced lower maximal levels of immunoreactive plasma hGH and between 7 and 9 h after treatment higher plasma levels when injected subcutaneously in rabbits, (2) 125I-labelled hGH added as a tracer to hGH in gelatin was removed more slowly from subcutaneous injection sites in rabbits than 125I-labelled hGH given with hGH in glycine buffer and (3) changes in the ratio of hGH to gelatin had little effect on the time-course of plasma levels of hGH in the rabbit. Addition of the protease inhibitors aprotinin or 6-aminohexanoic acid, to injection of hGH in gelatin or glycine did not induce any consistent increase in plasma levels of hGH.

ABSTRACT From the plasma of 30 out of 51 patients with various metabolic disorders a »growth-hormone-like« factor was concentrated which when injected into hypophysectomized rats increased the width of the tibial epiphysis. A similar factor had previously been concentrated from the plasma of acromegalic patients. It was tentatively concluded that this factor was identical with human growth hormone (HGH). Diabetes mellitus. Of 40 patients with diabetes mellitus 24 showed elevated plasma levels of human growth hormone (HGH). The frequency of elevated plasma levels was higher in young diabetics than in older diabetic patients; in many cases a nondiabetic complication was associated with an elevated level. In the plasma of 4 patients with diabetes mellitus and liver diseases an elevated plasma level of HGH was found while in 3 patients with Kimmelstiel-Wilson's syndrome no increase of HGH was found. Liver diseases. In the plasma of 4 patients with various liver diseases an elevated plasma level of HGH was found while in the plasma of another 4 patients no increase of HGH was found. Hypercholesterolaemia. In the plasma of 2 patients with familiar hypercholesterolaemia elevated levels of HGH was found while no HGH was found in a patient with an idiopathic type of the disease.

ABSTRACT Marked diurnal variations were found in plasma growth hormone (GH), insulin, acetoacetate (AcAc) and sugar in two herds (U and A) of dairy cows kept at two different levels of feeding. Seven animals from each herd were tested. The main diurnal variations were related to food intake, a significant increase in plasma insulin, and a significant decrease in plasma sugar being found. The acetoacetate level rose significantly during feeding in herd U (moderately underfed), while no significant increase was found in herd A (adequately fed). Plasma growth hormone was found to decrease (P < 0.01) only during feeding in herd U, while no change in the GH level could be detected in herd A. The mean level of GH in herd U was found to be twice the value found in herd A. There were no significant differences between the herds in plasma insulin and sugar. Significant differences in plasma levels of GH, insulin and sugar were found between animals when analysed within the herds. Variations in the levels of insulin and acetoacetate were very small during the night. This is contrary to GH, which shows the least variation during food intake. The correlation coefficient between the plasma components was low, although in many cases significant.
