Healthy, and insulin-deficient (streptozotocin-induced diabetic, STZ) Sprague-Dawley rats were used to investigate the effects of different doses of ß-endorphin (25 and 50 µg/kg) on plasma ß-endorphin, insulin, glucagon, and glucose levels at 15- and 30-min time points. In experimental groups, plasma ß-endorphin levels were higher at the 15-min than at the 30-min time point in healthy rats; however, in STZ-diabetic rats, ß-endorphin levels were lower at 15 min than at 30 min, indicating that intraperitoneal absorption of ß-endorphin differed between healthy and insulin-deficient rats, ß-endorphin did not affect plasma glucose, insulin, or glucagon at either dose in the healthy group. In the insulin-deficient rats, ß-endorphin at 50 µg/kg reduced plasma glucose levels at the 30-min time point compared to the 25 µg/kg dose, without affecting plasma insulin. Moreover, ß-endorphin at 50 µg/kg decreased plasma glucagon levels at the 15-min time point in comparison to the 25 µg/kg dose in insulin-deficient rats. Plasma glucose levels may be reduced in insulin-deficient rats at high ß-endorphin levels regardless of insulin status.

In this study, the effects of xylazine on serum levels of triiodothyronine (T3), tetraiodothyronine (T4), insulin (INS), and glucagon (GN) in dogs were investigated. The dogs before injection were used as control group (0 h). The dogs were injected with xylazine at 3 mg/kg, then blood was collected from the peripheral veins at 0.5, 2, 8, 24, 48, 72, and 120 h after the injection. Serum T3, T4, INS, and GN were measured by ELISA. The results revealed that the T3 level decreased in serum 0.5 h after the injection (P<0.05), while the change in T4 was not significant. The secretion of INS increased 8 h after the injection (P<0.05). The GN level increased 2 h and 8 h after the injection (P<0.05). However, all of these changes returned to the norm after 24 h.

Strenuous exercise was reported to involve the alteration in the release of some "stress" hormones such as growth hormone (GH), cortisol, catecholamines and appropriate adjustment of energy metabolism but the relative contribution of these hormones to metabolic response, to cycling exercise performed at different muscle shortening velocities, has not been clarified. Aims: The purpose of this experiment was to assess the effect of applying different pedalling rates during a prolonged incremental cycling exercise test on the changes in the plasma levels of growth hormone, cortisol, insulin, glucagon and leptin in humans. Material and Methods: Fifteen healthy non-smoking men (means ± SD: age 22.9 ± 2.4 years; body mass 71.9 ± 8.2 kg; height 178 ± 6 cm; with VO2max of 3.896 ± 0.544 l . min-1), assessed in laboratory tests, were subjects in this study. The subjects performed in two different days a prolonged incremental exercise tests at two different pedalling rates, one of them at 60 and another at 120 rev . min-1. During this tests the power output has increased by 30 W every 6 minutes. The tests were stopped when the subject reached about 70 % of the VO2max. Results and conclusions: We have found that choosing slow or fast pedalling rates (60 or 120 rev . min-1), while generating the same external mechanical power output, had no effect on the pattern of changes in plasma cortisol, insulin, glucagon, glucose and leptin concentrations. But, generation of the same external mechanical power output at 120 rev . min-1 causes more stepper increase (p < 0.01) in the plasma growth hormone concentration [GH]pl and plasma lactate concentrations [La]pl when compared to that observed during cycling at 60 rev . min-1. We have also found that the onset of a significant increase in [GH]pl during cycling at 60 rev . min-1 was not accompanied by significant increase in [La]pl. While during cycling at 120 rev . min-1 the onset of a significant increase in [La]pl occurred without increase in [GH]pl, but with continuation of exercise when plasma [La]pl increased, there was also a parallel rise in plasma [GH]pl, as reported before. This results indicates that the increase in [GH]pl during exercise is not closely related to the increase in [La]pl.
