[Functional study of the pancreatic alpha and beta cells of normal aged subjects, using a standard meal]

Modifications in glycaemic, insulinaemic and pancreatic glucagon levels have been studied in 20 normal elderly subjects and in 20 young adults (controls) following a standard meal. Results showed that glycaemia is higher and insulinaemia rises more slowly in the elderly, while serum glucagon values show no substantial variations in the two groups of subjects.
