恶性肿瘤的病因和细胞癌变的规律至今尚不完全清楚。我们以往曾对肝癌和皮肤癌进行过初步的实验研究,认为癌变的发生可能与细胞的增生与分化间的平衡失常有关。为了进一步研究癌变的原理,本实验进行了二乙基亚硝胺(DENA)诱发大鼠肝癌过程中肝脏病理形态观察和生化改变的研究。DENA在自然界比较广泛地存在于食物中,可诱发多种动物肿瘤。在大白鼠所诱
The etiology of malignant tumors and the laws of cellular carcinogenesis are still not fully understood. We have conducted preliminary experimental studies on liver cancer and skin cancer in the past and we believe that the occurrence of cancer may be related to the imbalance between cell proliferation and differentiation. In order to further study the principle of canceration, the study of liver pathological morphology and biochemical changes during rat liver cancer induced by diethylnitrosamine (DENA) was performed. DENA is widely present in food in nature and can induce a variety of animal tumors. Inspired by rats
