1. Regulation of magnesium balance is poorly understood. However, hypomagnesaemia has been reported in patients in clinical situations where circulating catecholamines are raised including myocardial infarction, cardiac surgery and insulin-induced hypoglycaemia stress tests. 2. The effects of l-adrenaline infusions, sufficient to achieve pathophysiological levels of adrenaline, and of therapeutic intravenous infusions of salbutamol, a β2-agonist, on plasma magnesium, plasma potassium, plasma glucose and plasma insulin levels were studied in a placebo-controlled design in eight normal subjects. 3. Plasma magnesium levels fell significantly during the adrenaline infusion and also during the salbutamol infusion, though more slowly. In a 1 h period of observation after cessation of the infusions no recovery of plasma magnesium levels was seen. Significant falls in plasma potassium levels were also observed during both infusions with spontaneous recovery within 30 min after the infusions. 4. No significant changes in plasma insulin levels occurred with either salbutamol or l-adrenaline compared with control. Plasma glucose levels rose significantly during the adrenaline infusion. 5. The study suggests that both l-adrenaline and salbutamol cause shifts in plasma magnesium which are not mediated by insulin. We propose that intracellular shifts of magnesium occur as a result of β-adrenergic stimulation.

The ability of timed daily increases in ambient temperature (from 22 +/- 1 degree C to 40 +/- 1 degree C for 2 h) to alter body fat stores, blood lipid levels, and insulin resistance were tested in male Holtzman rats. Of the six times of day tested only temperature pulses administered 16 h after light onset consistently decreased body weights, retroperitoneal fat stores, and plasma insulin levels. Subsequently, temperature pulses were administered either 0 (TP0) or 16 (TP16) h after light onset (light-dark 12:12 h). While no differences were observed between the TP0 group and the constant temperature (22 degrees C) controls, decreases in body weight gain, food consumption, retroperitoneal fat stores, and plasma concentrations of insulin, cholesterol, and triglycerides were consistently observed in the TP16 group. Although changes in plasma glucose during an oral glucose tolerance test were similar when the two treatment groups were compared with their respective controls, glucose tolerance was achieved with less insulin in the TP16 animals than in their respective controls. Insulin effectiveness was greater in the TP16 group as indicated by a decrease in plasma glucose, after insulin injection, that was of greater magnitude and longer duration than in controls. Hence, timed daily increases in ambient temperature may decrease obesity in part by decreasing plasma insulin levels apparently as a consequence of increased tissue sensitivity to insulin (greater glucose tolerance and less insulin intolerance). Because the treatment is effective only at a particular time of day the findings support a role for circadian neuroendocrine interactions in the regulation of these metabolic states.

Swim training alters cardiovascular, sympathoadrenal, and endocrine responses to hemorrhage in borderline hypertensive rats (BHR). The effects of 10, 20, and 30% blood volume hemorrhages on cardiovascular, sympathoadrenal, and endocrine function in swim-trained (T; 2 h/day, 5 day/wk for 10-12 wk) and age-matched, untrained, sedentary, control (UT) borderline hypertensive rats (BHR) were assessed. Heart rate (HR) in UT BHR was significantly greater during the baseline (rest) period than T BHR. HR increased slightly from baseline in both groups after 10% hemorrhage but was significantly decreased in both groups after 20 and 30% hemorrhages. The decrease was eliminated by atropine (1 mg/kg iv). Systolic (SBP) and diastolic (DBP) blood pressures decreased significantly after 20 and 30% hemorrhages in both T and UT BHR but were not different between the groups at these times. Plasma norepinephrine levels were significantly increased above baseline after 20 and 30% hemorrhages in UT BHR and were significantly greater in UT BHR than T BHR after 30% hemorrhage. Plasma glucose levels increased significantly after 30% hemorrhage in both groups but were significantly greater in UT BHR than T BHR. Both plasma norepinephrine and plasma epinephrine levels showed strong positive correlations with plasma glucose. After 20 and 30% hemorrhages, plasma insulin levels were unchanged in T BHR but were significantly decreased in UT BHR. Plasma insulin levels were significantly less in UT than T BHR after 30% hemorrhage. These results suggest that swim training alters the effect that hemorrhage exerts on endocrine and sympathoadrenal function in BHR.(ABSTRACT TRUNCATED AT 250 WORDS)
