The dietary effects of chicken treated with Hwangki-Beni Koji sauce (HBS) on reactive oxygen species (ROS) generating and scavenging related enzyme activities in rats fed with a high-fat and high-cholesterol diet were investigated. The rats (five rats per group) were divided into a normal control diet group (NC), a high-fat and high-cholesterol diet control group (HFC), HFC plus base sauce-treated chicken supplemented diet group (HFC-BS), and a HFC plus HBStreated chicken supplemented diet group (HFC-HBS), and fed for 5 weeks. Total type T (T) and type O (O) hepatic xanthine oxidoreductase in HFC-HBS were 27.91-35.78% and 24.57-31.84% lower than those of HFC and HFC-BS, respectively. In HFC-HBS compared with HFC and HFC-BS, superoxidase dismutase activity was 62.89-64.50% higher, glutathione S-transferase activity was 19.29-25.17% higher, glutathione content was 25.11-53.30% higher, and lipid peroxide content was 20.29-24.19% lower. Therefore, chicken treated with HBS may prevent liver damage by the ROS formed from a high-fat and high -cholesterol diet.

Hovenia dulcis extract (HDE) has positive effects on alcohol degradation, recovery of liver damage and antioxidant activities. This study examined whether HDE exerts an ameliorative effect on inflammatory orifacial pain in an animal algesic model with formalin. The animals (rats) were divided into four groups: group I (control), group II (right facial subcutaneous injection of 5% formalin, inflammatory orifacial pain group), group III (5% formalin + distilled water administration), and group IV injection (5% formalin + 4.5 ml/kg of HDE), respectively. The scores from the scratch and effleurage tests were applied to evaluate the differences between three groups. The expression of p38 MAPK, iNOS and Nrf2 in the brain and medulla oblongata, which are involved in pain regulation, inflammation, antioxidation and nitric oxide production, were analyzed by western blot. The degree of orifacial pain was significantly lower in group IV than in groups I, II and, III. The expression of p38MAPK, iNOS and Nrf2 in the brain and medulla were also lower in group IV than in the other groups. These findings suggested that a Hovenia dulcis extract can attenuate inflammatory orifacial pain by suppressing the expression of p38 MAPK, iNOS and Nrf2.

Objectives : We have studied to know analgesic effects of the combination of Aconitum Cilliare Tuber with honey in the models of peripheral neuropathic pain. Methods : Neuropathic pain model was made by ligating left 5th lumbar spinal nerve. After 3 days, combination of Aconitum Ciliare Tuber and honey extract was administrated each alternate day. Administration was divided three groups, that is NP-OA1(0.06 mg/ml), NP-OA2(0.24 mg/ml), and NO-OA3(0.96 mg/ml). After that, we examined the withdrawl response of neuropathic rats legs by von Frey filament and acetone stimulation. And also we examined c-Fos, glutamic oxaloacetic transaminase(GOT), glutamate-pyruvate transaminase(GPT) and change of weight. Results : Mechanical allodynia in NP-OA1 groups were significantly decreased compared with the control group. Cold allodynia in all experimental groups were no significant differences with the control group. c-Fos protein expression on the central grey, all experimental groups were lower than that of control groups. But, there were no statistically significant differences. Change of weight in all experimental groups were significantly increased compare with the control group. In blood serum GOT in NP-OA1, NP-OA2 groups were significantly decreased compare with the control group. In blood serum GPT in all experimental groups were no significant difference with the control group. Conclusions : We had noticed that the combination of Aconitum Ciliare Tuber and honey decreased mechanical allodynia in the model of neuropathic pain compared with the control group and it has not efficacy in elevation of GOT, GPT and weight loss etc., the element of which becomes damage to liver. This study can be proposed that Aconitum Ciliare with Honey may be applicable to neuropathic pain in clinic. But it is reliability not that cold allodynia and c-Fos expression have effectively to control pain. Therefore we have to follow up about that.

This study was carried out to investigate the effect of the active ingredients from ginseng on paraquat(PQ) toxicity. Oxidative stress was induced by intraperitreatneal injection of PQ at a single dose of 25 mg/kg. Saponin treated groups were given protopanaxadiol saponins(PPD) or protopanaxatriol saponins(PPT)(5 mg/kg, orally) per day for 1, 3, & 7 days. We also investigated the relationship between lipid peroxidation and ginseng saponins by measuring the levels of superoxide dismutase(SOD), catalase(CAT), glutathione peroxidase (GPx), reduced glutathione(GSH), malondialdehyde (MDA), and hydrogen peroxide(H$_2$O$_2$) in liver tissue. The activities of SOD, CAT, and GPx were generally high in the PPD group; the SOD activity on each day was the highest in the PPD group. The H$_2$O$_2$ content was the lowest in the PPD group. The GSH levels were significantly increased in the PPD. The levels of MDA(the end product of lipid peroxidation) were significantly lower in the red ginseng component groups than in the PQ group; the levels were especially low in the PPD groups. These results led us to conclude that the antioxidant effects of extracts from red ginseng prevent oxidative damage by direct antioxidant effects involving SOD, CAT, & GPx, and increasing the ability of the body to synthesize endogenous antioxidants.

Effects of Acanthopanax senticosus extract (AS) on blood sugar content and serum lipid profiles of streptozotocin-induced diabetic rats were investigated. Experimental groups were classified into four groups, that is, normal control (NC) group, diabetic mellitus (DM) group, AS-fed group and DMAS-fed group. The AS group showed lower feed efficiency than the NC group, but the efficiency of DMAS group was higher than DM group. DMAS group showed the decreased water intake and urine by $45.5\%$ and $23.7\%$ respectively, compared with DM group. Compared with DM group, DMAS group decreased blood sugar by $46.9\%$ and triglyceride by $17.8\%$, total cholesterol by $10.0\%$ and LDL cholesterol by $22.0\%$ in serum, but increased serum HDL cholesterol by $14.4\%$ The relative percentage of liver or kidney per body weight, and the serum ALT activity in DMAS group were lower than those of DM group. There were no significant differences in hepatic glutathione(GSH) contents and total xanthine oxidase(XOD) activities among experimental groups. The hepatic lipid peroxide(LPO) content in DMAS group decreased by $54.6\%$ compared with that in DM group. The XOD (O type) and the ratio of O type to total type of both STZ-treated groups (DM and DMAS) were higher than those of NC group, but less conversion of D to O type was observed in DMAS group than in DM group. There was no significant difference in GST activity between NC and AS, but STZ-treated groups showed lower glutathione S-transferase(GST) activity than NC. In conclusion, it seems that AS reduces blood sugar by inhibiting the activity of xanthine oxidase type O as an oxygen-free radical generating system which induces the tissue damage. Antidiabetic effect of AS may regulate diabetes-induced high lipid profiles in blood.

Metallothioneins (MT) are a group of low-molecular weight, cysteine-rich, intracellular proteins that are encoded by a family of genes containing at least 10 functional isoforms in human. The expression and induction of these proteins is associated with protection against DNA damage, oxidative stress, and apoptosis. Many studies have shown increased expression of MT in various human tumors, whereas MT is down-regulated in certain tumors such as hepatocellular carcinoma and liver adenocarcinoma. Hence, the expression of MT is not universal to all human tumors but may depend on the differentiation status and proliferative index of tumors, along with other tissue factors and gene mutations. Using Northern blot analysis, we found that laminin induced expression of MT-1 in HSG and PC12 cells, which can be differentiated by laminin, but had no effect on MB-231, MDA-435, and PC-3 cells, which cannot be differentiated by laminin. In addition, we analyzed the expression level of the MT-1 gene in five prostate cancer cell lines possessing different metastatic potential. The expression of MT-1 in normal and less malignant cells (RWPE-1 and WPE1-NA22) was high and up-regulated by laminin, whereas the expression of MT-1 in WPE1-NB14, WPE1-NB11, and WPE1-NB26 cells (malignant) was extremely low and not elevated by laminin. These results suggest that the MT-1 gene is involved in laminin-mediated differentiation and affects the metastatic potential of tumor cells.

The results of toxicity test using mice and rats for ethanol extract of Bracken Fern collected in Kwang Ju area were shown as follows ; Up to the dose of 10g per kg of mice administered intraperitoneally there was no lethal toxicity so that it was impossible to calculate the median lethal dose $(LD_{50})$. For the first 7 days experiment all rats administered frond extract grouping in 40mg, 400mg, and 1200mg per kg of rat as the daily oral doses did not show any characterized sign in the weight gain rate, anatomical findings, and biochemical studies. For 3 weeks following the first week the weight gain rates of all test group were reduced to $4.2{\sim}7%$ below the weight gain rate of control. In this period serum GPT, GOT, and Alkaline phosphatase value were increased significantly indicating the symptoms of Bracken Fern poisonings. The pathological findings of all test groups for 28 days showed acute and chronic intestinal lesion and liver damage with steatosis especially in 1200g/kg rat groups. In this experiment the Bracken poisonings appeared slowly in rats of 400mg/kg and 1200mg/kg for two weeks and in rats of 40mg/kg for 3 weeks, showing the symptoms of lowering of weight gain rate, subacute hepatitis, hepatic steatosis and enteritis in 28 days experiment.

Literatural study for Delirious speech and Fading murmuring, the results were as follows. 1. Delirious speech and Fading murmuring are given at the speech impediment. Derious speech to be out of language's order and slur the end of his words, and Fading murmuring is to repeat in losing conscious. 2. In constrast with Delirious speech and Fading murmuring, Maniac speech is induced by a general term for manic-depressive psychosis. Luoyan is to say in a feeble voice and mumble in a sleeping condition, and Paraphasia and Solioquy are appeared in a clear mental condition. The speech impediment is caused by damages of the nervous system and speech organ, and Yuyancuoluan is appeared in a feverless condition. 3. The symptoms of Delirious speech are to utter ravings and have a loud and heavy voice, and these resemble the delirium which specially has a speech impediment and muddle in the western medical world. The symptoms of Fading murmuring are to speak ambigously, repeatedly, and illogically and so are similar to the Wernicke dysphasia which is caused by a incomprehensible conversation. 4. The causes of Delirious speech are to spread a stomach heat and the lungs pathogenic qi into heart, not to sweat in cold damage, the Three Yang Combination of syndrome, stomach repletion, yang collapse due to excessive sweat, diarrhea, after diarrhea, heat to enter the blood chamer, feces to remain in the stomach, stasis blood to enter the viscera, to carry anger to extremity, and to be constipated. the cause of Fading murmuring is to despair vacuity desertion of vital essence and energy after a serious illness. 5. The causes of delirium are general infection, postoperative states, and metabolism disorders and those of Wernicke dysphasia are disorders of the blood vessel, brain tumors and traumas. 6. Delirious speech is cured with the discrimination of vacuity and repletion. Baitong Tang(白通湯), Chaihu Guizhi Tang(柴胡桂枝湯), Chaihu Jia Longgu Muli Tang(柴胡加龍骨牡蠣湯) are prescribed in case of vacuity, while Chengqi Tang(承氣湯), Baihu Tang(白虎湯), Liangge San(凉膈散) are in case of repletion. Fading murmuring is treated with Xiao Chaihu Tang(小柴胡湯), Fuzi Tang Jiawei(附子湯加味), Shengmai San(生脈散), and Renshen Sanbai Tang(人蔘三白湯). 7. To acupunture Qimen-Xue(期門穴) is required when it is late to prescribe a medical decoction or the hyperactive liver qi attacking the spleen.

Pronuclear microinjection (PMI) is a primary method for producing transgenic mice and offers a powerful tool for investigating gene function in vivo. The method has several reported advantages and disadvantages. Here, we report another potential shortcoming. The survival rate of fertilized one cell-stage embryos was significantly reduced after PMI procedure (65.4% (1202/1838)). In addition, the proportion of embryos developing to full-term was also significantly lower than that of embryos not undergoing PMI (26.5% (319/1202) vs 41.9% (57/136)). Moreover, 3 out of 21 (14.3%) founder control mice which were non-transgene-carrying littermates of transgenic founders showed histopathological changes in their liver, which was comparable to that in of transgenic lineages (4 out of 27 (14.8%)). In conclusion, the mechanical damages in chromosomes occurring during PMI procedure may be a potential factor influencing phenotypes of transgenic mice.
