Glucagon Effects on Ischemic Vasodilatation in the Isolated Rat Heart

Table 1

Histamine concentrations in the control (without glucagon) and test (in the presence of glucagon) groups taken during preischemic and reperfusion periods.

	Control group	Test group
Histamine concentration in preischemic period (𝜇M)	4.6±0.8⋅10^−8	5.1±0.6⋅10^−8
Histamine concentration within reperfusion period (𝜇M)	10.4±0.9⋅10^−8∗†	6.8±0.5⋅10^−8∗†

Values are represented as mean ± S.E.M.
(*) Represents significantly different values between control and test groups, 𝑃<.01; 𝑛=10.
(^†) Represents significantly different values between histamine concentrations in preischemic and reperfusion periods, 𝑃<.01; 𝑛=10.
