Abstract. The effects of somatostatin on the acute metabolic actions of insulin on newborn rat myoblasts in culture has been examined during monolayer culture. Somatostatin significantly inhibited the insulin-stimulated uptake of [3H]leucine and [3H]amino-isobutyric acid into myoblasts but had no effect on basal (unstimulated) uptake of these two substances. The lowest concentration of somatostatin to have a significant effect was 10 μg/l, and this was apparent in all the experiments undertaken. The inhibitory effect of somatostatin was seen at all effective concentrations of insulin used (0.3–1 U/l). These findings lend support to the concept of an endocrine role for somatostatin in vivo and suggest that a peripheral antagonism may exist between circulating insulin and somatostatin on anabolic processes such as nutrient uptake into cells.

Four patients with ampicillinuria and ampicillin crystalluria have been reported. The presence of ampicillin leads to false positive spots for leucine/isoleucine, phenylalanine, and β-amino isobutyric acid in paper chromatograms of the urinary amino acids, and to a false-positive spot for phenylalanine in paper electrophoretograms. Crystalluria, due to ampicillin, is also described. Its significance remains to be determined.
