  • BACKGROUND: The purpose of this study was that serum metabolic and hematological variables were measured to investigate the detoxication effect of Taraxacum mongolicum extract on male albino rat exposed with lead and mercury. METHODS AND RESULTS: For this study, Pb and Hg-exposed( 50 ppm) albino rats was used, and the treatments were carried out in three doses of 100 mg/kg, 200 mg/kg and 500 mg/kg as dry weight of T. mongolicum extract. T. mongolicum extract could improved the body weight gain and feed efficiency ratio, except to food intake. The levels of biochemical factors elevated by Pb-Hg mix exposure, which are Bilirubin, Alkaline phosphatase(ALP), glutamic oxaloacetate transaminase(GOT), glutamic pyruvate transaminase (GPT), lactate dehydrogenase(LDH), ceatinine and blood urea nitrogen(BUN), were significantly reduced in all treated groups as compared to Pb-Hg mix exposure alone. T. mongolicum extract was shown to suppress the accumulation of Hg and Pb in serum by dose dependent manner. CONCLUSION: Therefore, this study suggest that T. mongolicum extract might have the potential effect to minimize the toxic effects of Pb and Hg.

  • It has long been recognized that dropwort contains specific funtional subtances for protecting human liver and preventing and curing its diseases, and thus it has been widely utilized in traditional folk remedy. In the present study. fresh of fermented extract of dropwort shoots grown on dryland and fresh extract of those grown on flooded fie1d were fed to the rats suffering from acute, subacute or chronical toxication induced by alcohol administration, and their affects were investigated. Administration of alcohol to rats and mice for 2 days at 5ml of 30% EtOH/kg/day raised total cholesterol and total glyceride which were, however, great1y supressed when alcohol was administered to the laboratory animals previously fed on fresh or fermented extract of dryland dropwort, or fresh extract of flooded field-grown dropwort for 20 days, without significant differences among the extracts. The levels of alanine aminotransferase and aspartate aminotransferase which were raised by alcohol adminstration were also lowered by feeding dropwort extract, among which that of fermented dryland-grown one was more effective than the other two. Chronic alcohol toxication was induced to rats by administering 10% alcohol for 10 months and fermented dropwort extract or tap water was fed to the rats for 5 days. The rats fed on fermented dropwort extract were lower in total cholesterol by 40% and in tota1 glyceride by 60% than the control. Alanine aminotransferase and aspartate aminotransferase in the rats fed on fermented dropwort extract were decreased by 87.2% and 91.7%, respectively, compared to the control, and the rats recovered almost to normal. Activity of alkaline phosphatase, catalase, superoxide dismutase or glutathione peroxidase changed greatly by alcohol administration in the rats suffering from chronic as well as acute toxication. The extract of fermented dry land dropwort significantly lowed the activity of those enzymes, especially, alkaline phosphatase and superoxide dismutase. The present results suggesting the possible medicinal effect of fermented dropwort extract to liver diseases.

  • Acetaminophen(APAP) is one of the most extensively used analgesics and antipyreics worldwide. In order to investigate preventive effects of white and red ginseng extracts, male ICR mice pretreated with white or red ginseng extracts(50 or 250 mg/kg/day, for 5 days, orally) before treatment with acetaminophen(800mg/kg, i.p, single dose). In an attempt to elucidate the possible mechanism of hepatoprotective effect, superoxide dismutase(SOD), catalase(CAT), hydroperoxide, malondialdehyde(MDA) contents were studied. In pretreatment with red ginseng extract(250 mg/kg), the activities of SOD, CAT were generally highest and the hydrogen peroxide content was lowest. The levels of MDA were significantly lower in white and red ginseng extract groups than those in the APAP groups. By treatment with ginseng extract, high content of hydrogen peroxide and increased lipid peroxidatiion level caused by APAP could be lowered. Also, ginseng extracts were found to increase antioxidative enzyme activity. Finally, the results suggest that the antioxidant effects of (white and red) ginseng extracts prevent oxidative damage by direct antioxidant effects involving SOD, CAT and increasing the ability to synthesize endogenous antioxidants. It was concluded that ginseng can protect against APAP intoxication through its antioxidant properties.

  • The growth of weeds and some other plants has been considered to be inhibited by sicklepod(Cassia tora L.) sharing the habitat. The study was conducted, for the first time, to propose that this phenomenon is not only due to competition for physical and nutritional conditions but also due to allelopathy. In addition, autotoxicity of sicklepod was examined. The results are summarized as follows. 1. Rice sheath length reduced progressively from 18 % to 36 % with increasing the concentration of treating aqueous extracts of sickle pod seeds, but rice germination was not affected. In contrast, radish hypocotyl length was not reduced by the aqueous extract treatment but radish germination was significantly reduced by 66 % at 1 : 10 and 1 : 5 treatment. 2. Total chlorophyll contents in rice seedling decreased from 50 % to 65 % by treatment of seed aqueous extracts diluted from 1 : 50 to 1 : 5 ratio. 3. Aqueous extracts of sicklepod leaves significantly reduced hypocotyl length and fresh weight in radish and germination in rice, but mung bean was slightly affected by aqueous extracts only in fresh weight. 4. Volatiles from fresh, immature seeds with husk reduced the radish germination and seedling growth and radish root growth appeared to be more sensitive to the exposure to volatiles from fresh immature seeds than both germination and hypocotyl growth. 5. Volatiles from sickepod leaves inhibited germination and growth of radish, rice and mung bean, and seedling growth was more sensitive to volatiles from leaves than germination. 6. Volatiles from sicklepod leaves reduced germination and radicle length of sicklepod itself. 7. Collectively, it is concluded that there are water-soluble and volatile substances responsible for allelopathy in sicklepod.

  • Erectile dysfunction (ED), also known as impotence, is the inability to attain and sustain an erection firm enough to have sexual intercourse. Frequent ED may be a symptom of health problems including heart disease, obesity, alcoholism, stress, smoking, and depression, that need treatment. This study aimed to effect of complex extract (CPL) including Cornus officinalis on sexual function factor in the erectile dysfunction rat model. The erectile dysfuction rat model was induced by cimetidine (500 mg/kg in 5% ethanol, oral injection 2 weeks). Rats were oral administered with different concentration of CPL in rat erectile dysfunction model. As a results, sexual function factors (NO, cGMP) significantly improved in CPL treated groups (CPL-300, 600, 900 mg/kg) compared to CON group. Serum testosterone was increased in a dose-dependent manner after CPL treatment. Furthermore, administrations of CPL restored lumen areas of the prostate in the erectile dysfunction rat model. These results indicated that CPL alleviated erectile dysfunction by increasing sexual function factor and testosterone in rat model. CPL could be used to natural treatement for erectile dysfunction. However, further study is required to identify active ingredient and its mechanism of erectile dysfunction.

  • The effects of Pueraria flos (PF) and Pueraria radix (PR) water extract on the hepatic alcohol metabolic enzyme activities were examined in rats that were orally administered ethanol (25% v/v, 5g/kg body weight/day) for 5 weeks. The PF and PR water extract were supplemented in a diet, based on 1.2 g or 2.4 g of raw PF or PR/kg body weight/body. Alcohol administration without the PF or PR supplementation significantly decreased net weight gain, feed intake and feed efficiency ratio. However. both dose of the PF of PR supplementation resulted in significant enhancement of growth and suppression of increased relative weight of liver, brain and heart by alcohol administration. Activities of hepatic alcohol dehydrogenase and microsomal ethanol oxidizing system were higher in the alcohol treated group than in the normal group, while aldehyde dehydrogenase activity was significantly lowered in the alcohol treated group. The hepatic metabolic enzyme activities altered by alcohol administration were normalized by both doses of PF or PR supplement. Hepatic monoamine oxidase activity and hydrogen peroxide, which were significantly higher in the alcohol treated group than in the normal group, were also decreased by the supplementation with either PF or PR. These results indicate that low-or high-supplementation of either water extract PF or PR may alleviate ethanol-induced hepatotoxicity by altering alcohol metabolic enzyme activities.

  • The purpose of this study was to demonstrate the effect of Momordica Charantia L. water extracts, one of the natural chelator, on the biochemical and enzyme activity changes in the rats liver and kidney caused by lead acetate. Rat approximately 250 g in weight were grouped into the control, lead acetate treated, and the Momordica Charantia L. boiling water extracts treated after lead acetate groups. Lead acetate (1,000 ppm) and Momordica Charantia L. water extracts (5%, 10%) were delivered drinking water. Serum AST, ALT and BUN were measured, histological alteration of liver and kidney were examined by light microscopy. Momordica Charantia L. extract group was decreased serum AST, ALT and BUN level induced by lead. Optical observations of liver tissue, lead group were observed necrosis of hepatic cells and infiltration of inflammatory cells, but Momordica Charantia L. extract group was observed only slight infiltration of inflammatory cells around the central vein. Optical observations of kidney tissue, lead acetate induced atrophy and necrosis of glomerulus and infiltration of inflammatory cell around renal tubule. For the group treated with Momordica charantia L. extract, the glomerulus was similar to the control, some around the renal tubule was observed infiltration of inflammatory cells. In conclusion, Momordica Charantia L. water extract may protect the lead-induced toxicity on liver and kidney.

  • This study was designed to investigate the effects of Korean Pueraria radix extract in Pb administered rats. Pb exposed rats were given 1% Pb in the diet. $\delta$-Adminolevulinic acid(DALA) and urinary glucose levels were increased with Pb administration and were lower in the Pb group than in the group administered Pb alone. Hematocrit value was decreased with Pb administration and was higher in the Pb group than in the C-Pb grou. $\delta$-Aminolevulinic acid dehydratase (DALAD) activity was decreased in the Pb group. ALT and AST were increased by Pb added and were lower in the Pb group than in the C-Pb group. Serum Pb content was higher in the Pb exposed rats than in the control groups, and no significant difference was found due to extract of Pueraria radix supplementation. Levels of liver, kidney and femur lead were reduced by Pueraria radix. Lead contents in feces and urine were higher in the Pb added groups than in the control group, and level of feces lead was increased by extract of Pueraria radix.
