Insulin levels during the oral glucose tolerance test (OGTT) of adult (PND121) control and PNS rats, characterized as passive or proactive coping. On PND121, rats received an oral gavage of 2-mg/kg glucose at t = 0. Blood sample for plasma insulin analysis were taken before gavage (t = 0) and 15, 30, 45, 60, and 120 minutes after gavage. A, Insulin levels during an OGTT of rats on a chow diet. White symbols, proactive coping; gray symbols, passive coping; triangles, control; circles, PNS. B, Insulin levels during the OGTT for rats on high-fat diet. White symbols, proactive coping; gray symbols, passive coping; triangles, control; circles, PNS. C, Area under the curve for insulin response of rats on either a chow or a high-fat diet. White bars, proactive coping; gray bars, passive coping; open bars, chow diet; hatched bars, high-fat diet; an A indicates a significant difference between control and PNS rats, P < .05; a B indicates a significant difference between chow and high-fat diet-fed rats, P < .05; a C indicates a significant difference between passive and proactive-coping rats, P < .05; a D indicates a significant difference between passive PNS rats and all other groups, P < .05.
