The ultrastructural morphology of hamster cheek pouch epithelium
Archives of Oral Biology, 1981Abstract The ultrastructure of the keratinizing stratified squamous epithelium is described in detail, with particular emphasis on the changes occurring in the constituent cells, cellular organelles and intercellular junctions during epithelial differentiation.

Dinitrochlorobenzene contact hypersensitivity in the hamster cheek pouch
Journal of Oral Pathology & Medicine, 1976Abstract.Stimulation of cell mediated immunity has been reported to be effective in bringing about clinical regression of carcinomas. The purpose of this pilot study was to investigate the possibility of introducing cell mediated immunity into an experimental animal‐chemical carcinogenesis system (dimethylbenzanthracene‐hamster cheek pouch) to serve as

EXPERIMENTAL CUTANEOUS VASCULITIS IN HAMSTER CHEEK POUCH CHAMBERS
The Journal of Dermatology, 1984ABSTRACTInduction of cutaneous vasculitis has been attempted in hamster cheek pouch chambers. Only slugging of blood flow and narrowing of blood vessels were noted in the chambers by injecting a mixture of antigen and antibody at an antibody excess ratio.

The development of the syrian hamster cheek pouch
The Anatomical Record, 1986AbstractThe objective of this study was to provide a detailed account of the morphogenesis and early cytodifferentiation of the hamster cheek pouch. Although the newborn “cheek pouch” is used for in vitro studies of the effects of retinoids and carcinogens, its rudimentary structure has not been adequately described.

Hamster Cheek-pouch Testing of Dental Soft Polymers
Journal of Dental Research, 1991The hamster cheek pouch provides a suitable model system for the mucous-membrane irritation testing of dental materials. Poor retention of materials or difficulties in histopathological interpretation caused by surgical artifacts have been reported in published techniques.

p53 alterations in chemically induced hamster cheek-pouch lesions
Molecular Carcinogenesis, 1996To confirm that the hamster cheek-pouch carcinogenesis model reflects development of human squamous cell carcinoma (SCC), we determined if and when p53 mutations occur in the development of SCC in this model by using immunohistochemical staining and polymerase chain reaction (PCR)-single-strand conformation polymorphism (SSCP) analysis plus direct DNA ...

Chemical Carcinogenesis in the Hamster Cheek Pouch
Pathobiology, 1975Squamous cell carcinomas were induced in the hamster cheek pouch with 9,10-dimethyl-1, 2-benzanthracene. The process of carcinogenesis was inhibited by phenylphosphate, an inducer of alkaline phosphatase. Orthophosphate and <i>l-</i>phenylalanine, which inhibit alkaline phosphatase, had a promoting effect on tumor formation. The results are

The effects of 4-hydroxyanisole on hamster cheek pouch
Experimental and Molecular Pathology, 1969Abstract Hamster cheek pouches were regularly treated with 4-hydroxyanisole and biopsies were taken at intervals for histology and electron microscopy. An initial erythema progressively increased and by 40 days epithelial hyperplasia and hyperkeratosis were evident, accompanied by the formation of small bullae.

Cheek pouch capacities and loading rates of heteromyid rodents
Oecologia, 1997Rodents of the family Heteromyidae are proficient gatherers and hoarders of seeds. A major component of their adaptive specialization for harvesting and transporting seeds is their spacious, fur-lined cheek pouches. Precise measurements of cheek pouch capacities are essential if ecologists are to understand the foraging ecology, possible constraints on
