Table I. Characteristics of sham-operated and infarcted SD rats.
Table II. infarct Size And Resting Values Of Mabp And Heart Rate In Sham-operated And Infarcted Rats Before Intracerebroventricular Infusion Of Acsf, Vp Or—{d(ch2)5[tyr(me)2ala-]vp} (V1ant).
Figure 1 (A) Comparison of changes in MABP from baseline in the sham-operated and the infarcted (MI) rats during i.c.v infusions of VP V1 receptor antagonist (V1ANT), *—significant differences between the corresponding means in the rats with and without the infarct, #—significant difference from baseline. (B) Changes in resting MABP from baseline during i.c.v. infusion of aCSF, arginine VP and VP V1ANT in the sham-operated (upper part) and the infarcted (MI, lower part) rats. Number of rats in the groups: sham CSF—9, sham VP—8, sham V1ANT—8, infarct CSF—8, infarct VP—8, infarct V1ANT—8. Means ± standard errors are shown. The symbols indicate significant differences between the corresponding means in different groups of experiments:+ − significant difference between aCSF and VP groups, #—significant difference between aCSF and V1ANT groups, *—significant difference between VP and V1ANT groups. The results were considered significant if P < 0.05.
