[0023] 1. Experimental method
[0024] 1.1 Grouping 64 healthy male SD rats, weighing (200±20) g, provided by the Animal Research Center of Weifang Medical College, were raised in an SPF rat breeding room, and caged for 7 days before the test to adapt to the environment. One week before irradiation, 64 SD male rats were randomly divided into blank control group, model group, proanthocyanidin (treatment) group and dexamethasone combined with cephalexin western medicine (positive control) group, with 16 rats in each group.
[0025] 1.2 Drug preparation: Accurately weigh an appropriate amount of proanthocyanidins and add them to sterile physiological saline to dissolve, stir evenly, and obtain a proanthocyanidin solution with a concentration of 2.5-3.75mg / ml. Ready to use now, keep away from light. The proanthocyanidin group began to inhale proanthocyanidin through the lungs on the first day after irradiation. Positive control drug: dexamethasone combined with cephalexin, dexam...
