Experimental paracoccidioidomycosis of hamster inoculated in the cheek pouch
Mycopathologia, 1994We compared the granuloma morphology and immune response of hamsters inoculated with Paracoccidioides brasiliensis (Pb) into the cheek pouch, which lacks lymphatic drainage, and into the footpad, which is rich in lymphatics. Our objective was to better understand the modulation of Pb granuloma in an immunocompetent animal inoculated in an ...

Response of cheek pouch autografts to DMBA painting
Oral Surgery, Oral Medicine, Oral Pathology, 1966Abstract Sections of hamster cheek pouch mucosa were autografted in surgically prepared beds in the clipped dorsal skin areas of the same animals. After the graft and dorsal skin area had been painted with 0.5 per cent DMBA three times per week for 15 weeks, papillomas were induced in the dorsal skin in 100 per cent of the hamsters and in only 5 per ...

Long‐term organ culture of hamster cheek pouch mucosa
Journal of Oral Pathology & Medicine, 1976Abstract.Explants of cheek pouch mucosa from 12‐ to 48‐hour‐old hamsters have been maintained in organ culture for up to 49 days with excellent preservation of tissue integrity and relationships. The technique uses gelatin sponge matrix in Leighton tubes with Eagle's Minimum Essential Medium (M.E.M.) supplemented with 10% calf serum and antibiotics.

Chemotherapy against human melanoma in the hamster cheek pouch
Journal of Surgical Oncology, 1980AbstractHuman malignant melanoma was transplanted to the cheek pouch of immuno‐suppressed (corticosteroid‐treated) hamsters. Significant differences were observed in tumor growth constants for animals treated with methotrexate, DTIC, BCNU, and vincristine (P < 0.05) compared to controls. However, no appreciable effect was demonstrated for Adriamycin,

Evolution of Cheek Pouches in African Pouched Rats (Rodentia: Cricetomyinae)
Journal of Mammalogy, 1989There are two subfamilies of murid rodents whose members possess spacious internal cheek pouches with retractor muscles: Cricetinae and Cricetomyinae. In cricetine hamsters, the pouch is retracted by a muscle derived from the trapezius muscle group and innervated by cranial nerve XI.

Incisional Biopsy and Seeding in Hamster Cheek Pouch Carcinoma
Journal of Dental Research, 1984Surgical blades were contaminated by doing incisional biopsies on DMBA-induced cheek pouch carcinomas in hamsters. Contaminated blades were then used to: (1) make cytologic smears; (2) make incisions in the mucosal surface of the lower lip; (3) make incisions in the ventral surface of the tongue; (4) make incisions in the untreated left cheek pouch ...

The hamster cheek pouch model for field cancerization studies
Periodontology 2000, 2014AbstractExternal carcinogens, such as tobacco and alcohol, induce molecular changes in large areas of oral mucosa, which increase the risk of malignant transformation. This condition, known as ‘field cancerization’, can be detected in biopsy specimens using histochemical techniques, even before histological alterations are identified.

Microvascular responses to aldosterone in hamster cheek pouch microcirculation
Clinical Hemorheology and Microcirculation, 2013The aim of the present study was to assess the in vivo effects of aldosterone topically applied on the hamster cheek pouch microcirculation under baseline conditions or during ischemia-reperfusion. Male Syrian hamsters were anesthetized, tracheotomized and intubated.

Comparative morphology and evolution of cheek pouches in rodents
Journal of Morphology, 1986AbstractThere are two types of cheek pouches in extant rodents. Internal cheek pouches are evaginations of the oral cavity deep to M. platysma and M. sphincter colli profundus, and have evolved independently in some species of the superfamilies Sciuroidea and Muroidea. External, furlined cheek pouches open lateral to and separate from the oral cavity, (

The Hamster Cheek Pouch Model of Carcinogenesis and Chemoprevention
1992The Syrian golden hamster cheek pouch carcinogenesis model is probably the best-known animal system for studying events involved in the development of premalignancy and malignancy in human oral cancer. Like the mouse skin model of carcinogenesis, the hamster cheek pouch model provides data on the effect of carcinogens, promoters, and chemopreventive ...
