本文企图进一步研究γ射线对鸡疟红内期的作用,确定γ射线照射红内期和红外期疟原虫在鸡诱发的保护性兔疫程度,并找出这种免疫是否为期的特异性。作者采用一日龄的白莱克鸡,疟原虫为鸡疟原虫8B,用连续血液传代保种,每月经埃及伊蚊周期性转种,红内期疟原虫取自稀释浓度为每毫升10~7虫数的小鸡血液。红外期(EE)疟原虫采用经孢子体感染的小鸡的脑悬液,钴~(60)照射强度为2Kci,产生γ射线平均能量为1.25MeV照射量。小鸡4周内,
This paper attempts to further study the effect of γ-rays on the internal period of malaria malaria and determine the protective rabbit-induced degree of malaria infection induced by malaria parasite in the red-phase and the red-phase in γ-ray irradiation and find out if this kind of immunity is of specific period. The authors used a one-day-old white lake chicken, Plasmodium chicken Plasmodium 8B, with continuous blood subculture, the monthly Aedes aegypti mosquitoes periodically transplanted red-phase Plasmodium taken from the diluted concentration of 10 to 7 per milliliter Worm number of chickens blood. Infrared (EE) plasmids were infected with sporozoites in chickens. The cobalt (60) irradiation intensity was 2 Kci and the average γ-ray energy was 1.25 MeV. Within 4 weeks of chickens,
