Homoeopathically prepared Condurango 30C is traditionally used in amelioration of certain types of cancer by homeopathic practitioners. In this study, ability of Condurango 30C in amelioration of the conventional benzo[a]pyrene (BaP)-induced lung cancer in rat has been tested. After one month of scheduled oral feeding of BaP, lung cancer is routinely developed after four months in rats. Tumorbearing rats were then treated with Condurango 30C for the next one ($5^{th}$), two ($6^{th}$) and three ($7^{th}$) months, respectively, and sacrificed. Efficacy of post-cancer treatment by Condurango 30C was evaluated against controls (placebo) by different study parameters like: body and lung weights, number and diameter of lung tumour nodules, lung architecture, DNA damage, anti-oxidant activity and reactive oxygen species (ROS) accumulation. Administration of this homeopathic remedy caused increase of body weight and decrease of lung weight, decrease in number and diameter of lung tumour nodules, particularly after one and two months of drug treatment. BaP intoxication significantly increased lipid peroxidase (LPO) with concomitant decrease in activities of different antioxidants, while Condurango 30C administration certainly reduce their levels than normal and cancerous groups, notably after one and two months' of drug treatment. Condurango 30C showed capability to induce ROS-mediated cell death evidenced from the study of ROS activities at different time-points. Further, the remedy possibly achieved its anticancer goal through mediation of DNA-nicks that possibly led cancer cells to the apoptotic pathway. Thus, Condurango 30C has anticancer potential in BaP-induced lung cancer of rats via tissue damage recovery and ROS-mediated programmed cell death.

In this study, we investigated the preventive effects of the mulberry leaf tea fermented by Monascus pilosus on high fat-induced obesity, hyperlipidemia, and fatty liver in mice. Non-fermented mulberry leaf tea powder (UM) and fermented mulberry leaf tea powder (FM) were supplemented with high-fat diet at 2% (wt/wt) dosage for 8 weeks. Both UM and FM lowered body weight gain, feed efficiency ratio, epididymal fat, serum triglyceride, total cholesterol and LDL-cholesterol increased markedly with high fat diet (HC) in mice. FM showed more significant effects when it was compared with UM. In addition, Hepatic lipid peroxides and xanthin oxidase activities of the UM and FM were significantly lower than those of HC, despite the lack of a big difference in the amount of hepatic GSH. Activities of ROS scavenging enzymes and serum alanine aminotransferase activity were also examined as a parameter of hepatic damage. The UM and FM groups showed a recovery to NC group from significant changes induced by HC. Finally, histopathological analyses of liver samples revealed a decrease of lipid accumulation in hepatocytes in the UM and FM groups. These results suggest that UM and especially FM can reduce the development of obesity, hyperlipidemia and fatty liver.

The present study was carried out to investigate the effects of zinc and vitamin E on the antioxidative defense mechanism in the liver of streptozotocin(STZ)-induced diabetic rats. Levels of blood glucose of STZ-diabetic rats were higher than that of control, but ZDM($ZnSO_{4}$ 10mg/kg injection+STZ) group was lower than those of DM(STZ injection) and EDM(vitamin E 400mg/kg diet+STZ) group. Levels of plasma insulin were lower in all three STZ-diabetic groups than those of control. Thiobarbituric acid reactive substances(TBARS) peroxide values(LPO) in liver were increased 2.3-fold in DM group compared with those of control, while LPG in ZDM group was lower than that of DM group, and EDM group had similar tendency compared with that of control. Reduced glutathione(GSH) contents of liver were decreased in DM group compared with those of control, but increased 2.3, 1.7-fold in ZDM and EDM groups, respectively, compared with those of DM group. Oxidized glutathione(GSSG) was increased in DM group compared with control and GSSG in ZDM and EDM group were lower than that of DM group. GSH/GSSG ratio had similar tendency compared with results of GSH. The activities of free radical scavenging enzymes such as superoxide dismutase, glutathione peroxidase and glutathione S-transferase were significantly decreased in DM group compared to those of control, but higher in ZDM and EDM groups than those of DM group. The metallothionein contents in liver and kidney were increased in DM and EDM groups were remarkably increased 20, 5.3-fold in ZDM group, compared with those of control.

This study was designed to investigate the biochemical pollutant marker for diagnosis of marine pollutions by changes in oxygen radicals and their scavenger enzymes of the flounder (Pleuronichthys cornutus) in the Yellow Sea of Korea Protein contents in brain and muscle of wild flounders in the Yellow Sea were remarkably lower $(15\~45\%,\;and\;35\~45\%,\;respectively)$ than those of wild flounder in Pohang (control) of the East Sea. Lipid peroxide (LPO) levels in serum of wild flounders in the Yellow Sea were Significantly higher $(30\~70\%)$ than those of wild flounder in Pohang. Hydroxyl radical formations in serum of wild flounders in the Yellow Sea were significantly high $(15\~90\%)$ than those of wild flounders in Pohang. Superoxide dismutase (SOD) activities in serum of wild flounders in the yellow Sea were significantly lower $(20\~40\%)$ than those of wild flounders in Pohang, and glutathione peroxidase (GSHPx) activities in brain of wild flounders in the Yellow Sea were also significanlty lower $(10\~60\%)$ than those of wild flounders in Pohang. These results suggest that significantly decreases of protein contents in brain and muscle, remarkable in creases of malondialdehyde (LPD) in serum and decreases of SOD and GSHPx activities in serum and brain of wild flounders of the Yellow Sea may be used as a biochemical pollutant markers for diagnosis of marine pollutions.

The anti-obese, hypolipidemic and hepatoprotective effects of post-fermented green tea by Monascus pilosus was tested with mice fed with high-fat diet for 7 weeks. The body weight gain and feed efficiency ratio (FER) in normal control group (NC), CHA (2% non-fermented green tea powder supplemented high-fat diet group) and mCHA (2% green tea powder post-fermented by M. pilosus supplemented high fat diet group) groups were significantly lower than those of high fat diet control group (HC). Epididymal fat weight in mCHA and NC were significantly lower than HC. The hepatic lipid peroxide was dramatically higher in HC than that of NC and was significantly lower in CHA and mCHA. In addition, dehydrogenase type activity of xanthine oxidoreductase in HC was lower than that of NC, but significantly higher than CHA and mCHA. In histopathological findings, hepatic fat accumulation in HC was higher than that of NC, CHA and mCHA. Antiobese, hypolipidemic and antifatty liver effect of green tea powder post-fermented by M. pilosus was slightly higher than that of non-fermented green tea. In conclusion, the constituents of green tea fermented by M. pilosus has been proven to not only inhibit obesity and hyperlipidemia but also decrease the hepatic fat accumulation in high fat diet-induced obese mice.
