title: [The reactivity of the mesenteric arterioles to adrenaline in metabolic coma].
abstract: The reactivity of mesoappendix arterioles to applicated epinephrine application was investigated in 2 models of metabolic coma, hypoglycemic and acetonemic. Hypoglycemic coma (HC) was induced by insulin injection (20 IE/kg) i. m. to rats fasting for 18 hours. Acetonemic coma (AC) was induced by i. v. acetone injection (5.5 mmol). The sensitivity of arterioles to applicated epinephrine did not change in HC and increased twofold in AC vs. the control values (p < 0.01). The reaction of arterioles to injection of double threshold dose of epinephrine in HC developed sooner and the degree of vasoconstriction was 41% higher than in controls. In AC the reaction developed two times sooner and the degree of arterioles constriction was 1.5 times higher vs. the control (p < 0.01).
