The objective of the present study was to determine wound healing activity of ethanolic extract of Selaginella bryopteris on rats. The whole plant of S. bryopteris Linn. was collected from Andhra Pradesh, India and extraction was done using ethanol. GC-MS analysis was performed to determine active metabolites present in the extract followed by determination of total phenolic and flavonoid contents. In vivo wound healing activity of ethanolic extract was evaluated using excision wound model. The extract was applied topically on animals by preparing ointment in two concentrations (5\% and 10\%) where soframycin (10\%) was taken as positive control. Antioxidant activity of S. bryopteris extract was observed by measuring oxidative enzymatic levels i.e. Superoxide dismutase (SOD), Catalase (CAT), reduced Glutathione (GSH) and lipid peroxidation (LPO) in animal tissues. Histopathological studies of excised skin were carried out after the experimental period. The contraction rate of the wound was higher and dose-dependent in rats treated with 5\% and 10 \% ointment of extract in comparison to untreated control group. The drug treated groups showed recovery phase and the percentage of healing was more in 10\% at the end of experimental period. Results exhibited sufficient insights on the healing process with normal recovery stages and restored oxidative enzymatic levels. Histopathological findings provided additional positive results; the dermis with proliferating capillaries and skeletal muscle were replaced by cellular fibrous tissue and collagen fibers. Overall, the results showed that ethanolic extract of S.bryopteris was an interesting traditional agent that possess significant wound healing activity.

Objectives: This study was carried out to investigate the chemo protective potential of Quercetin, an isolated compound from Argyreia speciosa, on N-methyl-N-nitro-N-nitrosoguanidine and NaCl-induced gastric carcinomas in Wistar rats. Methods: The rats were fed with a diet supplemented with 8\% NaCl and simultaneously given N-methyl-N-nitro-N-nitrosoguanidine. After administration of the carcinogen, quercetin was administered. The whole stomach and a part of duodenum were sampled, cut open and tumors were recorded. The specimens were histopathologically investigated and the expression of surviving was examined with immunohistochemical analysis. Results and Conclusions: The treatment with quercetin significantly increases body weight in the rats after N-methyl-N-nitro-N-nitrosoguanidine administration. Survivin expression in glandular stomachs of normal rats, of rats in adenocarcinomas and quercetin at dose dependent manner treated rats were 0\%, 90\%, 75\%, 33.3-25\%, respectively. Compared with the survivin expression in negative rats, the differences were significant. Compared with the survivin expression in normal rats, the differences were significant. Histological observations of stomach tissues too correlated with the biochemical observations. These findings indicated that the Quercetin treatment could stimulate immunity activity in rats with N-methyl-N-nitro-N-nitrosoguanidine induced gastric carcinoma and have pronounced effect on survivin which is an attractive target for gastric cancer therapy.
