Objectives : This study was undertaken to verify the effects of Massa Medicata Fermentata (MMF) on nonalcoholic fatty liver disease (NAFLD) using high fat diet-fed male mice. Methods : Fifty four male C57BL/6N mice (age matched) were used for all experiments. Nine standard chow diet-fed mice were used as normal group and forty five high fat diet-fed obese mice were randomly divided into 5 groups: control, atorvastatin-10mg/kg, MMF(1)-62.5mg/kg, MMF(2)-125mg/kg and MMF(3)-250mg/kg. After all groups were treated with several kinds of diets for 8 weeks, we measured body weight gain, adipose tissue weights, plasma lipid and glucose metabolism, visceral organ weights, histological analysis for liver on the mice. Results : MMF-treated mice had lower body weight gain compared with controls. Among MMF-treated mice, the effect was magnified in MMF(2). MMF(3)-treated mice had lower blood plasma total cholesterol (TC) and glucose level compared with controls. MMF decreased hepatic lipid accumulation, liver fibrosis and liver inflammation of mice compared with controls. The effects was maximized in MMF(2) and atorvastatin. Blood plasma aspartate aminotransferase (AST), alanine aminotransferase (ALT), ${\gamma}$-glutamyltransferase (${\gamma}$-GT) concentrations tends to be decreased by MMF compared with controls. Blood plasma AST, ALT, ${\gamma}$-GT concentrations and organ weights were not changed by MMF, indicating that all three kinds of MMF do not show any hepatotoxicity. Conclusions : These results suggest that MMF improves NAFLD by reducing body weight gain, hepatic lipid accumulation, liver fibrosis, liver inflammation.

The repeated toxicity of Gleditschia-saponin produced and provided by S.S. Bio-Tech Bench Co. was evaluated in Sprague-Dawley rats. Gleditschia-saponin was administered to rats by oral route at dose levels of high (180 mg/kg/day), medium (90 mg/kg/day) and low (45 mg/kg/day) once a day for 14 days. Saline was administered to another group of rats as control. Each group was consisted of 5 male and female rats. There were no dose-related changes in clinical findings, food and water consumption, organ weights, urine analysis, biochemical examination and hematological findings in all groups of animals treated with Gleditschia.- saponin, except body weights. Body weighs in male and female rats were increased significantly (p < 0.05) from day 4 to 14 in low, middle and high dose groups than control group. Body weight in high dose group was increased higher than control or low, middle dose groups on day 14. Gross and histopathological findings revealed no evidence of specific toxicity to Gleditschia.-saponin. Therefore, it was concluded that Gleditschia-saponin had no toxic or side effects in Sprague-Dawley rats in an repeated oral toxicity tests.

Historical control data have been shown to be valuable in the proper interpretation and validation of reproductive toxicology studies. The present data were compiled from rat fertility and early embryonic development studies conducted at Korea Institute of Toxicology during the 1994∼2001 period. These data were assembled in order to provide background information for the general and reproductive data collected in 11 fertility and early embryonic development studies using Sprague-Dawley rats obtain-ing from the Breeding Facility, Korea Institute of Toxicology, Korea. A total of 274 males and 274 females were used in these studies during the eight-year period. Parameters of fertility and early embryonic development included clinical sign, body weights, food consumption, organ weights, estrus cycle, copulation index, precoital time, fertility index, pregnancy index, sperm parameters, and early embryonic development parameters. Most of the values were comparable to the previous historical control data reported by other investigators. These data can be wed not only as a historical data base for the meaningful interpretation of data from reproductive and developmental toxicity studies, but also as a contribution to biological characterization of Sprague-Dawley rats.

This study was performed to investigate nutritional effect and the utilization possibility of rapeseed oil which could replace the imported edible oils and oil crops. The proximate compositions of a recommendable cultivar(Mokpo Dangyo 19) and a native kind(Asahi) and the characteristics of these rapeseed oils were analyzed. The animal experiment of these rapeseed oils was carried out during 8 weeks of growing periods after weanling. Forty male weanling Sprague-Dawley rats were randomly assigned to 3 diet groups of Dangyo 19 oil, Asahi oil and commercial Soybean oil. Mokpo Dangyo 19 variety contained more lipids than Asahi variety by 8% and there was no difference in physiochemical characteristics between Dangyo 19 oil and Asahi oil except that erucic acid was contained little in Dangyo 19 oil but 50% in Asahi oil. Body weight gain, FER(Feed efficiency ratio) and PER(Protein efficiency ratio) of rats fed Dangyo 19 oil were higher than those of rats fed Asahi oil and organ weights such as liver, kidney and epididymal fat pads weights of rats fed Dangyo 19 oil were significantly higher(P<0.05) thanthose of rats fed Asahi oil. the apparent digistibility of total diet and total lipid were higher in rats fed the diets containing Dangyo 19 oil than Asahi oil. The content of total lipid in heart in heart were not significantly different with dietary oil kinds. The content of total lipid in liver increased with age in all rapeseed oil groups.

This study evaluates the effect of Dioscorea japonica Thunb subfractions on hyperglycemia and the composition of energy metabolites in diabetic rats. Diabetes emllitus was induced in male Sprague-Dawley rats by an injection of streptozotocin(STZ) dissolved in a citrate buffer into the tail vein at a dose of 45㎎/㎏ of body weight. Diabetic rats were assigned to 6 groups; STZ-control, subfraction A, B , C, D and E groups. All groups were fed an AIN-76 diet. The second butanol fraction of Dioscorea administered orally with carboxymethyl cellucose for 10 days after the STZ injection Body weight gain, diet intake and organ weights were monitored Levels of hematocrit, blood glucose, liver and muscle glycogen were measured. Levels of cholesterol, triglycerides and free fatty acids were also assayed. Body weight losses were observed by subfraction A group. Liver and kidney weights were not affected in any of the subgractioned groups. The decrease of blood glucose in daibetic rats which were fed Dioscorea japonica Thunb was significantly greater than the dicrease of blood glucose in the STZ-control group. cholesterol plasma level was not influenced in any subfraction of Dioscorea japonica Thunb. Liver triglyceride levels were significantly lowered in subfraction A compared with the STZ-control group. This study's results suggest that oral administration of subfraction C of Dioscorea japonica Thunb frction is capabl of reducing blood glucose, plasma triglyceride and free fatty acid levels, and therefore Dioscorea japonica Thunb may contain antihyperglycemic compounds.

Purpose The purpose of this study was to investigate sub-chronic toxicity of scolopendrid pharmacopuncture in mouse and method of increasing output of scolopendrid pharmacopuncture. Methods In order to prove the clinical safety of scolopendrid pharmacopuncture during 90 days, We have observed the physical reaction(side effect) and clinical pathology test after scolopendrid pharmacopuncture treatment and investigated method of increasing Output of scolopendrid pharmacopuncture for 90%, 80%, 70% ethanol. Results In subchronic toxicity test, there was no significant sign in clinical sign, opthalmological values, body weights, hematological values and urinalysis values. And we could see that food consumptions and water consumptions increased significantly, albumin, triglycerides, GPT in blood chemical values and Liver, Testis(right) in organ weights changed significantly in some groups, compared with those in the S1 group. But these changes were observed within the scope of physiology. So there was no sign of toxication in subchronic toxicity test, and we can tell that NOAEL(No Observed Adverse Effect Level) is above 0.286mg/kg/day. And 70% ethanol solution of scolopendrid was yielded the most amount of substance. Conclusions This study demonstrates that scolopendrid pharmacopuncture is to treatment of safety for a long time and we can obtain much amount from 70% ethanol solution of scolopendrid.

The aim of this study was to evaluate the antitumor activities of Typhae pollen (TP) by confirming in vitro cytotoxicity and in vivo anti-tumor and immune-modulatory effect with anti-cachexia effect. The MTT assay is used in HepG2 cell to detect potential cytotoxic activities of aqueous extract of Typhae pollen (TPe). After HepG2 tumor cell implantation, eight mice per groups were assigned to six groups. Three different dosages of TPe (500, 250 and 125 mg/kg) were orally administered in the amount of $10m{\ell}/kg$ and sorafenib also administered 20mg/kg, every day for 35 days from 28 days after the tumor cell implantation. We observed the changes on body weights, tumor volume and weights, lymphatic organ, serum interferon $(IFN)-{\gamma}$ levels, splenocytes and peritoneal NK cell activity, splenic tumor necrosis factor $(TNF)-{\alpha}$, interleukin $(IL)-1{\beta}$, IL-10 contents. Periovarian fat weights, serum IL-6 levels, thicknesses of deposited periovarian adipose tissue and mean diameters were also detected to monitor the tumor-related anticachexic effects. In tumor masses, the immunoreactivities of cleaved caspase-3 and cleaved poly (ADP-ribose) polymerase (cleaved PARP) - apoptotic marks, cyclooxygenase-2 (COX-2), inducible nitric oxide synthases (iNOS) and tumor necrosis factor $(TNF)-{\alpha}$ were additionally observed by immunohistochemistry. The results were compared with sorafenib. Decreases of COX-2 were demonstrated in sorafenib and TPe treated mice and also increases of iNOS in tumor masses were observed in TPe, not in sorafenib. TPe increased periovarian fat pad weights compared with tumor-bearing controls and sorafenib treated mice. TPe showed increases of splenic $TNF-{\alpha}$, IL-10 and $IL-1{\beta}$, serum $IFN-{\gamma}$ and NK cell activities corresponding to increases of spleen weights, lymph node weights and non-atrophic changes of lymph nodes. Our results show oral treatment of TPe 500, 250 and 125 mg/kg has potent in vitro and in vivo antitumor activities through modest cytotoxic effects, immunomodulatory effects and apoptotic activities in HepG2 tumor cells. In addition, TPe can prevent cancer related cachexia.

The rodent Hershberger assay is considered as a potential short term in vivo screening method for the detection of androgenic or anti-androgenic compounds. The objective of this study was to evaluate the anti-androgenic activities of di(2-ethylhexyl) phthalate (DEHP), di(n-butyl) phthalate (DBP), and butylbenzyl phthalate (BBP). A 10-day Hershberger assay was performed using immature Sprague-Dawley male rats castrated at 6 weeks of age. Tastosterone propionate (TP, 0.4 mg/kg/day) was administered s.c. to castrated male rats and followed by flutamide (1, 5, 10, or 20 mg/kg/day) treatment for 10 days by oral gavage. Similarly, DEHP, DBP, or BBP were also administered by oral gavage at 250, 500, or 1000 mg/kg/day after TP (0.4 mg/kg/day) administration. As expected, flutamide significantly inhibited the TP-induced re-growth of seminal vesicles, ventral prostate, and Levator ani plus bulbocavernosus muscles (LABC) at 1 mg/kg/day and above, and Cowper's glands and glans penis at 5 mg/kg/day and above. DEHP significantly (p<0.05) decreased the seminal vesicles, ventral prostate, LABC and Cowper's glands weights at 1000 mg/kg/day. BBP at 1000 mg/kg/day significantly inhibited TP-induced re-growth of the LABC in the immature castrated male rats, whereas ventral prostate, seminal vesicles, and Cowper's glands weights were unaffected. In contrast to DEHP, DBP did not affect accessory sex organ weights at any concentration. Body weights, combined adrenal glands, and kidney weights were not affected, but liver weights were significantly increased at high dosages in the DEHP, DBP, and BBP treatment groups. Our observations strongly suggest that DEHP acts as an androgen antagonist at the high dose (i.e., 1000 mg/kg/day).
