흰불나방의 중장(中腸)에 미치는 $\gamma$ 선(線) 조사(照射)의 영향(影響)
Effects of Gamma Irradiation on the Mid-gut of Hyphantria Cunea
초록
흰불나방(Hyphantria cunea Drury)의 각(各) 변태단계(變態段階)에 따라
In this paper, the author studied the histological changes of the midgut cells of fall webworms(Hyphantria cunea Drury) through 1.75-7 krad of the whole body gamma irradiation according to their metamorphosis by comparing the contol group with the irradiated one through an optical microscope. Here the results were as follows: 1. The epithelium of midgut was composed of columnar, goblet and regenerative cells. 2. The effects of gamma irradiation were varied with the dosages and the stages during the metamorphosis. 3. The degree of histological change mode by irradiation was increased with the dosages. 4. Radiosensitivity was the highest in both last-stage larva and 8-day-old pupae.
