It was found that the vaccines used did not cause the adverse reactions such as hypersusceptibility and changes of feed intakes, and that 2 times of vaccinations of the vaccines all effectively enhanced the antibody levels, respectively, in which the No.Ⅲ vaccine stimulated antibody as rapid as the first vaccination was done while the No. I and No.Ⅱvaccines did not result in the antibody by the first vaccination. It was concluded that the No.

METHODS: The rabbit hindlimb normothermic tourniquet ischemia model was employed. The tendon on the dorsum of the foot was exposed for observation of microvessels. The responses of arterioles on tendon surface to topical application of 10(-6) mol/L noradrenaline, 10(-6) mol/l acetylcholine (an endothelium-dependent vasodilator) and 10(-4) mol/L nitroglycerin (an endothelium-independent vasodilator) were observed at the period of ischemia and following 30 minutes of reperfusion after 2 hours and 5 hours of ischemia by use of intravital microscopy.
