Effects of arachidonic acid, γ-linolenic acid and linoleic acid on insulin secretion.
In pancreatic perfusion experiments, an equilibration period of 20 min preceded time
0. After a baseline period of 10 min, arachidonic acid, or γ-linolenic acid or
linoleic acid (100 µM) was administered for 30 min followed by basal
medium (KRB) perfusion. The horizontal line indicates the presence of arachidonic
acid, γ-linolenic acid and linoleic acid. Values are means ± SE (n=4). Baseline
effluent concentrations of insulin were 4,172 ± 277
pg/ml, 2,384 ± 802
pg/ml, 3,541 ± 508
pg/ml and 1,199 ± 127
pg/ml for the control, arachidonic acid,
γ-linolenic acid and linoleic acid groups, respectively.
