Transplantation of a human lymphoma to the cheek pouches of unconditioned, adult golden hamsters resulted in permanently transplantable tumors which grow progressively and kill their hosts. This tumor system, GW-478, has a hamster-specific láclate dehydrogenase isoenzyme mobility pattern and both human and hamster glucose 6-phosphate dehyrogenase enzyme profiles when propagated in the hamster ...
ABSTRACT Hamster breeding is becoming increasingly popular, mainly because of the simplicity breeding, low cost, and characteristics these animals: they are small, quiet, do not require a large space. Because this ease keeping, some people choose to keep more than one animal same species in single enclosure. In cases, sociability can lead fights, hamsters extremely territorial animals, which ca...
The first report of a methylcholanthrene-in duced transplantable melanotic tumor in a Syrian golden hamster was published by Shubik and asso ciates (14). Spontaneous hamster melanomas have been reported by Fortner and Allen (1) and Greene (5). Shubik found that no metastases occurred even when the tumors attained a size of 4 cm. in diameter. Fortner and Allen, and Greene reported diffuse metast...
The mutagenic/carcinogenic activities of DEHP and MEHP were studied in bacteria and mammalian cells. MEHP but not DEHP exerted a dose-dependent DNA damaging effect to B. subtilis in Rec-assay. DEHP and MEHP showed mutagenic activities to S. typhimurium TA-100, with and without S-9 mix, respectively. MEHP produced not only the mutation in E. coli WP2B/r but also sister chromatid exchanges (SCE) ...
Cytoplasmic retinoic acid binding protein (cRABP) is present in human fetal pancreas and becomes nondetectable in the normal adult pancreas. The binding protein for retinoic acid becomes apparent again in pancreatic cancer. Similar fluctuations in the content of cRABP occur in the hamster. The binding protein is undetectable in the normal adult hamster pancreas, while it was detected in several...
