Time-dependent potentiation of insulin release induced by alpha-ketoisocaproate and leucine in rats: possible involvement of phosphoinositide hydrolysis.

abstract：:The migration of Tokelauans from a traditional atoll in the Pacific to urban New Zealand is associated with an increased prevalence and incidence of Type 2 (non-insulin-dependent) diabetes mellitus over the period 1968-1982. During the same period, a lesser but definite increase is seen among non-migrants in Tokelau. ...
