ATP-Mg++ (10 mumoles/100 g, iv) increased the LD50 for Salmonella enteritidis lipopolysaccharide (endotoxin) in male Holtzman rats (300 +/- 10 g) from 1.3 to 6.0 mg/rat. While endotoxin at 3 mg/rat iv 5 hr previously induced hypoglycemia to 12 +/- 4 mg/dl, ATP cotreatment blunted the hypoglycemia; i.e., plasma glucose values were 78 +/- 6 mg/dl. ATP treatment prevented the depression in gluconeogenesis induced by endotoxin as evaluated in vivo by the conversion of 14C-alanine to 14C-glucose. ATP treatment also reduced the hypercatabolism of U-14 C-glucose to 14CO2 in vivo and by epididymal fat pads in vitro. A role for ATP in preventing disruption of glucose homeostasis and development of endotoxin shock via counteracting insulin is suggested.

Several studies indicate that in rats changing the rhythm of feeding from nibbling to meal-eating results in hyperlipogenesis and higher body fat deposition. Among the factors influencing this phenomenon, the effects of age and duration of treatment are not yet clear. Male rats of 4, 6, 12 and 18 weeks have been meal-fed (two 1-hour meals per day) for 5, 10, 20 and 30 days. Pair-fed Nibblers were used as controls. Adipocyte diameters and number from epididymal adipose tissues were determined, and lipogenesis measured my glucose-U-14-C incorporation into lipids. The results show that cellularity, glucose-U-14-C incorporation into adipocyte lipids and CO2 and body fat deposition are not affected by short-term meal-eating treatment in growing animals. In the adult rats, only after 30 days do the parameters studied show significant higher values in the meal-eating animals. The results are discussed in view of the possible interrelationships among the different factors influencing animal response to modifications in feeding frequency.

The effects of testosterone (T) on uptake and mobilization of orally administered triglyceride were examined in male rats. In order to attempt to explain regional differences, adipose tissue metabolism was studied in vivo. (U-14 C) oleic acid in sesame oil was given by gastric gavage to male, sham operated, castrated and castrated + T substituted rats, and accumulation and half-life of radioactivity measured. In castrated rats in comparisons with sham-operated and castrated + T rats, serum T was absent, and body weight lower (p < 0.05 or 0.01), but adipocytes in retroperitoneal and mesenteric tissues became significantly heavier. Radioactivity (dpm/mg triglyceride) was higher, in retroperitoneal tissue at 4 hours, 7, 30 days, and in mesenteric tissue at 4 hours, and at 30 and 60 days after oral label administration (0.1 > p > 0.05 or p < 0.05), no differences were seen in epididymal or inguinal depots at 4 hours. When radioactivity was expressed per adipocyte, the castrated group showed significantly higher radioactivity when compared to sham and castrated + T groups at 7 and 30 days in retroperitoneal and at 60 days in mesenteric adipocytes (p < 0.05 or 0.01). Half life (T 1/2) of radioactivity was longer in mesenteric tissue in the castrated rats than the other two groups (sham group, 33 days +/- 2; castrated group, 58 days +/- 6; and castrated + T group, 39 days +/- 3, p < 0.05), but there were no differences between groups in retroperitoneal adipose tissue.(ABSTRACT TRUNCATED AT 250 WORDS)
