Effects of tetraiodothyronine and triiodothyronine on hamster cheek pouch microcirculation.
The aim of the present study was to assess the effects of topically applied triiodothyronine (T(3)) and thyroxine (T(4)) on the arterioles of hamster cheek pouch microcirculation in vivo. Microvessels were visualized using a fluorescent microscopy technique. Topical application of T(3) (3.08, 30.8, 61.5, 307, 615, and 6,150 nM/l) consistently induced dose-dependent dilation of arterioles within...
متن کاملCarcinogenesis in the Hamster Cheek Pouch
Pouches from three experimental and one control animal were excised for analysis at various times during the first week and thereafter each week of carcinogen application (9,10-dimethyl-l ,~-benzanthracene) until the 131h week, at which time large tumors were present in all remaining aninmls. IIistologic progression from normal through inflanmmtion, uniform hyperplasia, localized premalignant h...
متن کاملEffects of antioxidant enzyme overexpression on the invasive phenotype of hamster cheek pouch carcinoma cells.
To examine the role of reactive oxygen species on the invasive phenotype of cancer cells, we overexpressed manganese- and copper-zinc-containing superoxide dismutases (MnSOD, CuZnSOD) and catalase (Cat) in hamster cheek pouch carcinoma (HCPC-1) cells in vitro using adenoviral vector-mediated gene transfer. Hamster cheek pouch carcinoma cells were transduced with these adenoviral vector construc...
متن کاملCortisone and hamster buccal pouch carcinogenesis.
Ninety male Syrian hamsters, 3 months of age, were divided into 6 equal experimental groups of 15 animals. Two groups served as controls for 8and 16-week experimental periods. In the remaining 4 groups, the light buccal pouch was painted 3 times weekly with 9,10-dimethyl-l ,2-benzanthracene (DMBA) and sacrificed at 8 and 16 weeks. One 8-week and one 16-week experimental group were also injected...
متن کاملstudy the effects of low level laser diode on no production and healing of diabetic and cortisone acetate and normal wounded sd rats
nitric oxide (no) is a small molecule synthesized by most of mammalian cells with diverse biological activities including vasodilatation, host defense and wound healing. impaired wound healing is a common occurrence among diabetics and patients receiving glucocorticoid therapy. on the other hand the application of laser in biomedical area have been increased. thus, the current studies were desi...
