Ethanol induces compoundhemorrhagic gastric lesions and causes a dose-dependent decrease in the concentration of endogenous nonprotein sulfhydryls in rat gastric mucosa. Sulfhydryl-containing drugs protect rats from ethanol - induced gastric lesions. Based on this findings, we investigated the involvement of sulfhydryl compounds in the antioxidant effects of Puerariae radix, a traditional herbal medicine, against ethanol - induced gastric lesions in the absence and presence of iodoacetamide(IDA. sulfhydryl blocking agent) in rats. respectively. Because of the known role of sulfhydryls in gastric cytoprotection, its role in gastric antioxidation was of intrest. In vitro, Puerariae radix extract(PRE) reduced linoleic acid autooxidation and exert DPPH radical scavenging effect. In vivo. PRE increased antioxidants(SOD, catalase. GSH) and reduced lipid peroxide level in ethanol-induced gastric mucosal lesions. But treatment with PRE plus IDA significantly inhibit the antioxidant effects such as SOD and GSH but did not affect catalase levels. These results suggest that Puerariae radix may play roles in the gastric cytoprotection through antioxidant effects and increase of SOD activity and GSH level are dependent of endogenous sulfhydryls.

Platycodi Radix, the root of Platycodon grandiflorum, commonly known as Doraji, is used as a traditional oriental medicine. Extracts from the roots of P. grandiflorum have been reported to have wide ranging health benefits. In the present study, we investigated the effects of an aqueous extract from the roots of P. grandiflorum (AEPG) on the growth of human lung carcinoma A549 cells. results obtained are as fellow; AEPG treatment resulted in the inhibition of the cell viability of A549 cells in a concentration-dependent manner. Upon treatment with AEPG, A549 cells developed many of the hallmark features of apoptosis, including condensation of chromatin. Flow cytometry analysis confirmed that AEPG increased populations of apoptotic-sub G1 phase. Western blot and RT-PCR analyses indicated that the expressions of Bcl-2 was down-regulated but Bax was up-regulated in AEPG-treated A549 cells. AEPG-induced apoptotis of A549 cells was associated with proteolytic cleavage and activation of caspase-3, release of cytochrome C from mitochondria into cytosol and down-regulation of Akt and phospho-Akt proteins in a dose-dependent manner. Induction of apoptosis by AEPG treatment was associated with inhibition and/or degradation of apoptotic target proteins such as poly(ADP-ribose) polymerase, β -catenin and phospholipase C-γ1. AEPG treatment inhibited the levels of cyclooxygenases protein of A549 cells, which was associated with the inhibition of prostaglandin E2 accumulation in a concentration-dependent fashion. Taken together, these findings suggest that P. grandiflorum has strong potential for development as an agent for prevention against human lung cancer.

In order to evaluate the cytotoxic effect of reactive oxygen species(ROS), the cell viability was measured by MTT assay after cultured mouse hippocampal neurons were treated with various concentrations of xanthine oxidase(XO) and hypoxanthine (HX) for 5 hours. And also, the protective effect of Salviae Mutiorrhizae Radix(SMR) on XO/HX-induced neurotoxicity was examined in these cultures. XO/HX significantly decreased cell viability in dose. and time dependent manners when cultured mouse hippocampal neurons were treated with 5 ~ 40 mU/ml XO for 5 hours. In the protective effect of SMR, SMR increased cell viability dose-dependently after cultured mouse hippocampal neurons were preincubated with 3O ~ 12O ug/ml SM R for 2 hours. From these results, it is suggested that XO/HX is toxic on cultured mouse hippocampal neurons, and herbe medicine such as SMR is very effective in blocking the cytotoxicity induced by ROS.

Numerous lines of evidence indicate that some of the neurotoxicity associated with Alzheirner's disease (AD) is due to proteolytic fragments of the amyloid precursor protein (APP). Most research has focused on the amyloid p (AP). However, the possible role of other cleaved products of APP is less clear. Lately It has been reported that a recombinant carboxy-terminal 105 amino acid fragment (CT105) of APP induced strong nonselective inward currents in Xenopus oocyte. In a brain with Atheirner's disease (AD), to investigate the roles of carboxyl-terminal fragment (CT105) of amyloid precursor protein (APP) in apoptosis processes possibly linked to neurodegeneration associated with AD, we examined the effects of the CT of APP with 105 amino acid residues (CT105) on the alteration of apoptosis triggers in neubroblastoma cells. We have investigated whether Radix Polygalae and Rhizoma Acori Grammei mixture extract (RP+RAG) inhibits CT1O5-induced apoptosis of neuroblastoma cells. We found that RP+RAG inhibits CT105-induced apoptosis in SK-N-SH cel!s. Treatment of the cells with RP+RAG inhibited CT105-induced DNA fragmentation and Tunel assay of nuclear chromatin and inhibited the caspase-3 expression in SK-N-SH cells. As the result of this study, In RP+RAG group, the apoptosis in the nervous system is inhibited, the repair against the degerneration of neuroblastoma cells by CT105 expression is promoted. These results indicate that RP+RAG possess strong inhibitory effect of apoptosis in the nervous system and repair effect against the degeneration of neuroblastoma cells by CT105 expression

The purpose of this research was to investigate the effects of unripened fruits and ripened fruits of Rubus coreanus Miquel on murine peritoneal macrophages. The 70% ethyl alcohol extracts (20 or 100 mg/kg) of unripened fruits (RCE-I) and of ripened fruits (RCE-II) were administered p.o. once a day for 7 days to mice. RCE-II and RCE-II decreased the phagocytic activity of murine peritoneal macrophages and the production of nitric oxide. Also, RCE-I and RCE-II increased the production of tumor necrosis factor. a from peritoneal macrophages. In general, the immuno-suppressive action of RCE-I on macrophages was more potent than those of RCE-II. These results suggest that the fruits of Rubus coreanus Miquel regulates the non-specific immune response via decrease of phagocytic activity and increase of production of tumor necrosis factor-α from murine peritoneal macrophages.

Gamisoamsan is a prescription originated in Soamsan which is known as an anti-cancer remedy in the traditional Korean Medicine. To enhance the synergic effects of anti-cancer activity of Soamsan, this study reconstituted the original components of Soamsan with a slight modification and produced a novel herbal remedy, namely Gamisoamsan. To investigate the effects of Gamisoamsan on anti-cancer reaction, I studied the effects of Gamisoamsan on angiogenesis via chorioallantoic membrane (CAM) assay, corneal neovascularization assay and the effects on expression of growth factor which are VEGF, TGF-β, bFGF and IMUP-1. Anti-cancer effects of Garnisoamsan was also abserved through hematological parameters, tumor volume and survival rate in mice. Gamisoamsan inhibited embryonic angiogenesis of blood vessels in CAM assay and inhibited neovascularization of rat cornea. Gamisoamsan reduced cell proliferation in HT1080 cells and IC50 was 2.18 mg/ml. Gamisoamsan reduced the expression of VEGF, TGF-β, bFGF and IMUP-1 which was known as vascular growth factor and this effects of Gamisoamsan was predominant than VP-16. The treatment of Gamisoamsan decreased the CT-26 cell inoculated-tumor volume in mice colon adenocarcinoma and increased mice survival which was inoculated CT-26 cells. The results of the present study suggest that Gamisoamsan extracts has a potential anti-tumor activity and may be an useful remedy to prevent and/or treat cancer.
