Influence of colchicine on leukemogenic effect of x-ray, estrogen, methylcholanthrene, and urethan in mice.

چکیده
Colchieine had a significant inhibitory influence on the leukemogenic effect of estrogenic hormone in combination with either x-ray or urethan in mice. There was some suggestion that colchicine inhibited the induction of leukemia in mice by x-rays. Colchicine was not leukemogenic in low-leukemia strains of mice when administered alone. Colchieine did not affect spontaneous (presumably viral) leukemogenesis in AKR mice.

other respects. It induces pulmonary tumors in rodents (10, 11); when administered orally to mice, papillomas of the forestomach may appear (1). Urethan initiates skin carcinogenesis in mice, although when administered alone skin tumors do not appear (14). Hemangiomas of the mouse liver have been induced by this chemical (6). The objective of this investigation was to test the influence of this...

The influence of various compounds on pulmonary tumor formation in mice after a single dose of urethan was investigated. Pretreatment by the microsomal enzyme inducers chlordane, phénobarbital, and 0-naphthoflavone reduced the yield of lung tumors, but phenothiazine and diethylaminoethyl diphenyl valerate (SKF-525A) did not. None of these agents by themselves were carcinogenic to the mouse lun...

for lung tissue (29). Subsequently, it has been shown to produce tumors in a variety of tissues of the mouse (37). Hemorrhagic lesions (6, 34, 37) and hemangiomas (20, 22, 32) in the livers of mice have been observed following the administration of unethan. Heston et al. (18) provided data obtaine4 from unethan-tneated C3H mice that permitted the addition of hepatomas to the list of neoplasms i...

Urethan alone has been known to be slightly leukemogenic for newborn mice and even less so for the adults. The studies were made to determine whether infant mice have the same suscepti bility to leukemogenesis as newborns in relationship to the dose of urethan delivered. Urethan was injected repeatedly at 3 dose levels into C57BL x C3H Fi mice starting when less than 24 hr old or at 7 days of a...
