Objective : To localize and compare the cerebral regions- activated by the the stimulation of traditional and burning acupunctures in right Hap-Kok (LI4) acupoints. Methods : Thirty-four healthy normal volunteers (19 males, 15 females, age 31${\pm}$11 years) were studies by rest/acupuncture Tc-99m HMPAO SPECT using same-dose sequential injection method using right Hap-Kok(LI4), traditional and burning acupunctures. All images were spatially normalized and the differences between rest and acupuncture activation state were statistically analyzed using SPM 96. Results : Statistical analysis of the effect by the stimulation using traditional acupuncture in right L14 showed regional cerebral perfusion increase in right inferior frontal lobe, right straight gyrus, left anterolateral frontal lobe, left anteroinferior temporal lobe, left posterior temporal lobe, and left cerebellum. In the stimulation using burning acupuncture in right LI4, regional cerebral perfusion increased in right posterior prefrontal lobe, right precental gyrus, right postcentral gyrus, right poteroinferior temporal lobe, left precentral gyrus, left Broca's area, left anterior parietal lobe, left posterior prefrontal lobe, and left cerebellum. In right LA, diffuse perfusion increase were noted in the both inferior frontal lobe by traditional acupuncture compared to burning acupuncture. Conclusion : The results localized the cerebral areas showed the effect of the acupuncture on cerebral blood flow. The effects of traditional and burning acupunctures on cerebral blood flow were similar in right Hap-Kok (LI4) acupoints. But the effects of traditional acupunctures on cerebral blood flow are stronger than those of burning acupunctures on cerebral blood flow.

Effect of the egg yolks from laying hens intubated, p.o., astaxanthin (designated AEY) on the catabolic response overcome of mice was examined. Female ICR mice (6~7 weeks of age) were adapted in a temperature- and humidity-controlled house for one week and randomly divided into 5 groups (6 mice/cage/treatment). Mice were intubated p.o., AEY (5, 10 and 15 mg), control egg yolk (CEY, 10 mg), or fish oil (5 mg) dissolved in 0.2 mL phosphate buffered saline (PBS) every two days for 14 days. At day 15, the 0.1 mL of lipopolysaccharide solution (LPS, 30$\mu\textrm{g}$/0.1 mL 10 mM HEPES) was injected through tail vein, and then, the body weight of mouse and the amount of feed intake were measured over a period of 72 hours. Control group mice were received only PBS and LPS. AEY treatment suppressed the loss of mice body weight in a dose-response manner. Twenty four hours post LPS injection, the reduced body weight per mouse of AEY 5, AEY 10, and AEY 15 mg treatment groups was 3.70, 3.54, and 3.25 g, respectively. Body weight suppression effect of AEY treatment was greater than that of CEY, but less than fish oil. AEY treatment did not alter thymus weight, but increased the weight of spleen or liver. These results indicate that AEY suppressed the loss of body weight by LPS via any function of the spleen and/or liver.

Objective: Ovarian angiogenesis plays an important role in folliculogenesis. However, little is known about the expression of angiogenic factors during follicular development according to female age. Stromal cell derived factor-$1{\alpha}$ (SDF-$1{\alpha}$) plays a role in granulosa cell survival and embryo quality as an angiogenic chemokine. Leptin is also involved in folliculogenesis and angiogenesis. This study examined expression of SDF-$1{\alpha}$ and leptin, and their effects on the expression of angiogenic factors in the ovary during follicular development according to female age. Methods: Ovaries were collected from C57BL mice of two age groups (6-9 weeks and 24-26 weeks) at 6, 12, 24, and 48 hours after 5 IU pregnant mare's serum gonadotropin (PMSG) injection. The expression of ovarian SDF-$1{\alpha}$ and leptin mRNA was evaluated by RT-PCR. In the organ culture experiment, the ovaries were cultured in transwell permeable supports with Waymouth's medium treated with various doses of SDF-$1{\alpha}$(50-200 ng/mL) or leptin (0.01-1 ${\mu}g$/mL) for 7 days. Then, mRNA expression of vascular endothelial growth factor (VEGF), endothelial nitric oxide synthase (eNOS), and visfatin were examined in the cultured ovaries. Results: Expression of SDF-$1{\alpha}$ and leptin in the ovary was significantly lower in the aged mouse group compared to the young mouse group ($p$ <0.05). Expression of these two factors increased with follicular development after PMSG administration. SDF-$1{\alpha}$ treatment stimulated visfatin expression in a dose-dependent manner, while leptin treatment significantly increased eNOS expression. Conclusion: These results suggest that decrease of ovarian SDF-$1{\alpha}$ and leptin expression may be associated with aging-related reduction of ovarian function. SDF-$1{\alpha}$ and leptin may play a role in follicular development by regulating the expression of angiogenic factors in mouse ovaries.

This study was designed to evaluate the analgesic effect of bee venom (BV) Acupuncture into different treatment points, Chok-samni (ST36) and blank loci of the gluteal muscle and back. We investigated the changes in formalin-induced pain behavior according to the pretreatment with different concentrations of BV, thirty minutes before the formalin injection. The results were summarized as follows: 1. The formalin-induced pain behavior was suppressed by pretreatment with BV into Chok-samni (ST36) in a dose dependent manner. During the early phase, 0.08mg/kg of BV showed a statistically significant suppression in the formalin-induced pain behavior. Moreover, 0.008mg/kg, 0.016mg/kg, and 0.08mg/kg of BV, except 0.0016mh/kg of BV, had significant suppresive effects on the formalin-induced pain behavior during the late phase. Therefore, these data indicated that the suppressive effect of BV acupuncture on the formalin-induced pain behavior was stronger in the late phase rather than the early phase 2. In order to investigate the analgesic effect of BV acupuncture into different treatment points, the experimental animals were divided into three groups: Chok-samni (ST36) group, gluteal group and back group. In the Chok-samni (ST36) group, the formalin-induced pain behavior during all the phases was significantly reduced as compared with that of the back group. However, as compared with that of the gluteal group, the formalin-induced pain behavior in the Chok-samni (ST36) group was decreased only in the late phase, not in the early phase. The formalin-induced pain behavior in the gluteal group was significantly reduced as compared with that of the back group in the late phase, not in the early phase. We suggested that the analgesic effect of BV acupuncture into Chok-samni (ST36) was most effective among Chok-samni (ST36), gluteal, and the back groups in formalin-induced pain behavior.

It was reported that radiopharamaceuticals induced radiation adaptive response (RAR) in patients undergoing nuclear medicine imaging studies. Individual variations of RAR were not studied well. The purpose of this study was to evaluate individual variation of RAR in patients undergoing nuclear medicine imaging studies. Peripheral lymphocytes were collected from 23 patients undergoing $^{99m}Tc-diethylenetriamine$ pentaacetic acid $(^{99m}Tc-DTPA)$ renal scintigraphy, 18 patients undergoing $^{99m}Tc-methylene$ diphosphonate $(^{99m}Tc-MDP)$ bone scintigraphy and 21 patients undergoing $^{99m}Tc-tetrofosmin\;(^{99m}Tc-TF)$ scintigraphy were collected before and 4 hours after injection of radiopharmaceuticals. The lymphocytes were exposed to challenge dose of 2 Gy gamma rays using a cell irradiator. Numbers of ring-form (R) and dicentric (D) chromosomes were counted under the light microscope. and used to calculate the frequency of chromosomal aberration [Ydr=(D+R)/total number of counted lymphocytes]. Adaptation index (k) was defined 3s ratio of Ydr in conditioned lymphocytes over Ydr in unconditioned lymphocytes. Coefficients of variance of k in $^{99m}Tc-DTPA,\;^{99m}Tc-MDP\;and\;^{99m}Tc-TF$ were 35%, 34% and 21%, respectively k was not dependent upon age, sex, and underlying diseases. There was a wide variation of RAR induced by radiopharmaceuticals among patients undergoing nuclear medicine procedures. It remains to be determined for causes of such variation.

We have investigated the antimetastatic and antitumor effects of Ginsenoside Rh2 and ${\beta}-glucan$ unsing an experimental metastatic mouse model intravenously injected with B 16 melanoma F 10 cells. Animal groups are divided into six groups according to the dosage of drug administration and the kind of drugs. The groups are control, ${\beta}-glucan$ with 50, 100 and 200 mg/kg, Geinsenoside Rh2 50 mg/kg, and ${\beta}-glucan$ 50 mg/kg + Ginsenoside Rh2 50 mg/kg. Oral administration of various concentration of ${\beta}-glucan$( 50, 100, and 200 mg/kg) were reduced the lung- metastatics induced by metastatic B16 melanoma F 10 cells injection with a dose dependent manner in the syngenic mice. At same dosage group, Ginsenoside Rh2 (50 mg/kg) has more antimetastatic effect than the ${\beta}-glucan$(50 mg/kg). The highest antimetastatic effects was observed in the ${\beta}-glucan$ 50 mg/kg + Ginsenoside Rh2 50 mg/kg group and has a similar tendency in the anti-tumor effects, including decrease of the average tumor weight and increase of the average survival rate. There are no differences of the average tumor weights were apparent in the ${\beta}-glucan$ groups, however there were little decrease of the average tumor weight in Ginsenoside 50 mg/kg group and ${\beta}-glucan$ 50 mg/kg + Ginsenoside Rh2 50 mg/kg group than that of the control group. The rate of average survival rate in the ${\beta}-glucan$ 50 mg/kg + Ginsenoside Rh2 50 mg/kg group, ${\beta}-glucan$ 200 mg/kg, ${\beta}-glucan$ 100 mg/kg and ${\beta}-glucan$ 50 mg/kg, and Ginsenoside 50 mg/kg groups were highly in order. These data suggest that antimetastatic and antitumor effect of combination of Ginsenodide Rh2 and ${\beta}-glucan$ be the highest in this study.

Objectives: The stomach is a sensitive digestive organ that is susceptible to exogenous pathogens from the diet. In response to such pathogens, the stomach induces oxidative stress, which might be related to the development of both gastric organic disorders such as gastritis, gastric ulcers, and gastric cancer, and functional disorders such as functional dyspepsia. This study was accomplished to investigate the effect of Ganoderma lucidum pharmacopuncture (GLP) on chronic gastric ulcers in rats. Methods: The rats were divided into 4 groups of 8 animals each: the normal, the control, the normal saline (NP) and the GLP groups. In this study, the modified ethanol gastritis model was used. The rats were administrated 56% ethanol orally every other day. The dose of ethanol was 8 g/kg body weight. The normal group received the same amount of normal saline instead of ethanol. The NP and the GLP groups were treated with injection of saline and GLP respectively. The control group received no treatment. Two local acupoints CV12 (中脘) and ST36 (足三里) were used. All laboratory rats underwent treatment for 15 days. On last day, the rats were sacrificed and their stomachs were immediately excised. Results: Ulcers of the gastric mucosa appeared as elongated bands of hemorrhagic lesions parallel to the long axis of the stomach. In the NP and GLP groups, the injuries to the gastric mucosal injuries were not as severe as they were in the control group. Wound healings of the chronic gastric ulcers was promoted by using GLP and significant alterations of the indices in the gastric mucosa were observed. Such protection was demonstrated by gross appearance, histology and immunehistochemistry staining for Bcl-2-associated X (BAX), B-cell lymphoma 2 (Bcl-2) and Transforming growth factor-beta 1 (TGF-${\beta}1$). Conclusion: These results suggest that GLP at CV12 and ST36 can provide significant protection to the gastric mucosa against an ethanol induced chronic gastric ulcer.

The effect of green tea drinking on the hepatocellular chemical cacinogenesis have been studied. Placental glutathione S-transferase(GST-P) positive foci area in a liver tissue, contents of thiobarbituric acid reactive substances(TBARS), total cytochrome P450 and glucose 6-phospphatase(G6P) activity in hepatic microsomes were investigated. Weaning Sprague-Dawley male rats were fed AIN-76A diet with deionized water or green tea infusion, Rats of CTR and CTR+ groups were provided deionized water while GTI and GTI+ groups were provided green tea instead of deionized water for the entire experimental period of 13weeks. Rats of GTP and GTP + groups had deionized water for the first 6 weeks and switched to green tea for the last 7weeks of the experimental period. CTR+, GTI +, and GTP + groups were carcinogen treated groups, Diethylnitrosamine(DEN) was injected as a single dose of 200mg/kg body weight intraperitoneally after 4 weeks of feeding. 2-Acetyla-minofluorene(AAF) was used as a carcinogen proliferater and suppled in the diets of carcinogen treated rats as 0.02% content for the last 6weeks starting from 2weeks after DEN injection. Rats were sacrificed after 13week weeks of feeding. The area and number of GST-P positive foci detected in carcinogen treated rats were decreased by green tea ingestion but when timing and duration of green tea ingestion was delayed after promotion period as in GTP + group, GST-P positive foci were not decreased as much as in GTI+ group. TBARS contents of carcinogen treated rats decreased by 13weeks of green tea ingestion but GTP groups did not show statiscally significant differences. G6P activities tended to decrease by carcinogen treatment but changes were not statiscally significant by green tea ingestion. Total cytochrome P450 contents were increased by carcinogen treatment. Thirteen weeks of green tea ingestion (GTI) also increased to total cytochrome P450 contents while 7weeks of green tea ingestion(GTP) did show any effects. These results suggest that green tea has suppressive effects on hepatocellular chemical carcinogenesis probably through the activities of antioxidant compounds.

Background: Cisplatin is one of the most extensively used chemotherapeutic agents for the treatment of cancer, including bladder, and ovarian cancers. However, it has been shown to induce nephrotoxicity, despite being an outstanding anti-cancer drug. In this study, we investigated the protective effect of dopaol ${\beta}$-D-glucoside (dopaol) on cisplatin-induced nephrotoxicity. Methods and Results: To confirm the protective effect of dopaol on cisplatin-induced nephrotoxicity, HK-2 cells were treated with $20{\mu}M$ cisplatin and $80{\mu}M$ dopaol. Cisplatin increased apoptosis, caspase-3 activity and mitochondrial dysfunction; however pretreatment with $80{\mu}M$ dopaol successfully attenuated apoptosis, caspase-3 activity and mitochondrial dysfunction. To evaluate the protective effect dopaol on cisplatin-induced nephrotoxicity in vivo, we used an animal model (balb/c mice, 20 mg/kg, i.p. once/day for 3 day). The results were similar to those obtained using HK-2 cells; renal tubular damage and neutrophilia induced by cisplatin reduced following dopaol injection (10 mg/kg, i.p. once/day for 3 day). Conclusions: These results indicate that dopaol treatment reduced cisplatin-induced nephrotoxicity in vitro and in vivo, and can be used to treat cisplatin-induced nephrotoxicity. However, further studies are required to determine the toxicity high dose dopaol and the signal pathways involved in its mechanism of action in animal models.

Purpose: This study was conducted in order to investigate the protective effects of ethanolic extract of Acanthopanax koreanum Nakai (AE) against carbon tetrachloride ($CCl_4$)-induced liver injury in rats. Methods: Male Sprague-Dawley rats were randomly divided into four groups in order to receive the following experimental diets with intraperitoneal injection of $CCl_4$ (2.0 mL/kg body weight, 20% solution 0.65 mL) for eight weeks (n = 8 per group): $CCl_4$ control (CON), $CCl_4$ + AE 1% (AE1), $CCl_4$ + AE 3% (AE3), or $CCl_4$ + acanthoic acid 0.037%, which is equivalent to AE 3% (AA). Results: Highest serum ALT activity and albumin level were observed in the $CCL_4$ control group, but showed a significant decrease by either AE or AA supplementation in a dose-dependent manner (p = 0.0063 and 0.0076, respectively). Both hemotoxylin and eosin staining and Masson's staining indicated remarkable prevention of $CCl_4$-induced liver damage in the AE3 group. $TNF{\alpha}$ and IL-6 production were significantly lowered in the AE treated groups, but not in the AA group (p = 0.0016 and p = 0.0002, respectively). The effects of AE3 were greater than those of AA for inflammation and liver toxicity biomarkers. Conclusion: Taken together, the results suggested that ethanolic extract of Acanthopanax koreanum Nakai provided hepatoprotective effects, leading to the reduction of inflammatory response. In addition, the effect of AE was superior to that of single compound AA.
