저자는 0.5% DMBA를 협낭에 도포하여 상피암을 유발한 hamster 21마리를 실험험군으로

하고 생리식염수를 도포한 hamster 14마리를 대조군으로 하여, 이 중 실험군 18마리와 대

조군 12마리에 체중㎏당 5 ㎎의 bleomycin을 복강내주입하여 bleomycin 투여전 및 투여후

1, 3, 7, 14, 21, 28일째 실험군 3마리, 대조군 2마리 씩을 희생 시켜서 이하선을 적출

하여 통법에 따라 Hematoxylin-Eosin중염색과 periodic acid Schiff염색을 하여 다음과

같은 결론을 얻었다.

1. 실험군의 bleomycin투여전의 이하선의 손상은 약물의 과다도포, 도포부위의 확산과

암조직에 따른 조직의 변성과 염증의 파급에 기인하는 것으로 사료된다.

2. 대조군의 이하선은 약제 투여후의 1일째 부터 혈관의 울혈상이 현저하였다.

3. 실험군의 이하선은 약제 투여후 3일째가 손상이 가장 심했으며 7일째 부터는 회복상

을 보이기 시작했다.

4. 실험군의 이하선은 선포의 손상이 도관의 손상보다 심하였다.

5. 실험군은 약제 투여전 부터 혈관의 확장상과 임파구의 침윤을 보였으며 임파구 침윤

은 7일째부터 소실되었으며 혈관 확장상은 14일째부터 감소상을 보이나 충혈은 계속되었

다.

6. PAS반응에서 대조군 선포는 다소 불규칙한 강양성을 나타냈으나 도관구조는 정상과

유사하였다.

7. PAS반응에서 실험군 선포는 불규칙한 반응을 보이다가 21일째는 정상으로 되었으며

도관조직은 14일째 부터 정상과 별차 없었다.





EXPERIMENTAL STUDY ON THE EFFECT OF ELEOMYCIN ON THE SAIVARY GLAND IN THE HAMSTER

WITH DMBA-INDUCED ORAL EPIDERMOID CARCINOMA

This study was undertaken to investigate the effects of bleomycin on the parotid

gland of the hamster with oral carcinoma.

The Golden Syrian Hamsters -7 weeks of age, about 100 gram of body weight - were

used.

Twenty one hamsters, developed epidermoid carcinoma in the buccal pouch by

painting 0.5% DMBA every other day for 12 weeks, served as experimental group, and

fourteen hamsters, treated with saline solution with same method, served as control

group.

Both the eighteen experimental and the twelve control group hamsters were

injected intraperitoneally 5mg of bleomycin per kg of body weight with single dose

respectively.

The hamsters were sacrificed before administration and 1, 3, 7, 14, 21, 28 days

after administration of bleomycin.

The parotid glands were removed, and processed in a routine manner for H-E stain

and PAS stain.

After microscopic observations, following results were obtained.

1. The tissue damage of the experimental group before administration of bleomycin

may be construed due to application over dose, painting excessive area,

inflammation or tisssue degeneration by cancer.

2. The parotid gland of the control group revealed marked blood conjestion 1 day

after administration of bleomycin.

3. The parotid gland of the experimental group showed the most destructive

feature on the 3rd day, and began to recover from 7 days after administration

4. The tissue damage of the experimental group was more prominent in the acini

than in the ducts.

5. There were dilatation of blood vessels and infiltration of lymphocytes. The

latter disappeared 7 days after administration, and the former diminished gradually

14 days after administration. But blood vessels were conjested continuously.

6. In PAS reaction, the acini of the control group showed a little irregular

positive reaction, but the ducts were within normal limits.

7. In PAS reaction, the acini of the experimental group showed irregular positive

reaction and recovered 21 days after administration, but the ducts showed normal

appearances 14 days after administration.
