  • This study was designed to observe the effect of hot water soluble polysaccharides extract(PS) from Lentinus edodes on the enzyme activities related with hepatic function and peroxidation in the rats fed better yellow. The four groups of male SD rats were fed with the diets contained 15% casein(basal diet; NO group), added butter yellow(BO group) or /and PS(NP, BP group) for 6 weeks. The activities of ${\gamma}$-GTP and GPT in BP were significantly lower compared with BO. The activities of glutathione peroxidase, catalase and lactate dehydrogenase were not significantly different between NP and NO, while those activities were significantly lower value in BP than BO. The activities of glutathione S-transferase of the microsomal and cytosol fractions were significantly lower in BP than in BO. The contents of glutathione and malondialdehyde in the liver were considerably low value in BP. In a view of these results the PS of Lentinus edodes prevents the lipid peroxidation and diminishes the liver toxicity caused with better yellow. The superoxide dismutase activity in cytosolic fraction of liver was not found any effect in all groups. But hepatic function enzyme activities such as catalase and glutathione peroxidase, LDH activities were remarkably decreased in the groups 2(basal diet + PS) and the ${\gamma}$-GTP, GOT and GPT activities, too. In liver, the contents of glutathione decreased by PS supplementation but HDL-cholesterol and total cholesterol ratio in plasma decreased at the groups 3, 4. The ${\gamma}$-GTP, GOT and GPT in plasma were remarkably higher in the rats fed the p-DAB than the control group, too. But above enzyme activities significantly decreased in the groups fed PS.

  • The purpose of this study was to probe the influences of krill (Euphausia superba) meal supplementation on a dose effect relationship between fluoride levels of krill meal and serum hepatic functional enzyme activity such as alkaline phosphatase (ALP), aspartate aminotransferase (AST), alanine aminotransferase (ALT), and lactate dehydrogenase (LDH) in rats fed experimental diets for 5 weeks. There were no significant differences in the activities of ALP, AST, ALT, and LDH in sera among krill meal diet groups (KM10, KM20, KM30). However, these groups were significantly (p<0.05) lower enzyme activities than control group (CG). The fluoride levels of sera and organ tissues (liver, brain, heart, lung, kidney) in krill meal diet groups (KM10, KM20, KM30) were significantly increased by adding krill meal in comparison with CG. The results indicate that a difficult to found toxicity to the liver from krill meal diet groups.

  • Diabetes mellitus has been known to be a state of increased oxidative stress. Free radical formation and lipid peroxidation are accelerated in this metabolic disorder. Buchu (Allium tuberosum Rottler) contains lots of antioxidative nutrients such as chlorophyll, vitamin C, $\beta$-carotene, phenolic compounds and sulfur compounds. To investigate the protective effects of buchu, 10% lyophilized buchu diet was fed to streptozotocin (STZ)-induced diabetic rats for 14 weeks and lipid peroxidation, protein oxidation, contents of reactive oxygen species, activities of antioxidative enzymes and contents of accumulated lipofuscin were measured as indicators of oxidative stress. Hepatic MDA and carbonyl contents tended to decrease in 10% buchu diet group compared with control group. Dietary buchu significantly suppressed lipid and protein oxidation in the skin of rats (p<0.05). Contents of hepatic hydroxyl radicals, which exert the highest toxicity among the reactive oxygen species, were significantly decreased in rats fed 10% buchu diet (P<0.05). Activities of antioxidative enzyme, such as superoxide dismutase, catalase, and glutathione peroxidase, tended to increase in liver and skin of rats fed 10% buchu diet, while hepatic catalase activity was significantly increased in buchu group compared with control group. Buchu supplementation significantly inhibited the accumulation of lipofuscin, an end-product of lipid peroxidation reactions induced by reactive oxygen radicals, in eye tissues compared with control diet (p<0.001). In conclusion, buchu supplementation diminished the oxidative stress, so dietary buchu could help to attenuate diabetes complications.

  • To evaluate an effect of liver xanthine oxidase on the induction of liver damage, carbon tetrachloride (CCl4) was intraperitoneally injected twice at 0.1ml/100g body weight to the rate fed a low (LP)or high protein diet(HP) while the control group fed LP or HP received only olive oil. The changing rate of liver xanthine oxidas activity was compared with that of a free radical generating enzyme, liver aniline hydroxylase and a scavenging enzyme, glutathions S-transferase activity between the rate fed a LP and those fed HP, and the two groups treated with CCl4. Concomitantly, the degree of liver damage which could be considered as the paramete for CCl4 metabolism in case of CCl4-intoxicated animal was observed in the present experimental conditions and the effect of allopurinol, xanthine oxidase inhibitor, on the CCl4-toxicity of rate liver was alos demostrated. On the other hand, the comparative effect of actinomycin D on the liver and serum xanthine oxidase of CCl4-treated rats fed HP with that of those fed LP and the kinetics of purifed liver enzyme from the liver of CCl4-treated rats fed HP was also compared with that of those fed LP to clarify the differences of xanthine oxidase activity between two groups. The increasing rate of liver weigth/body wt, serum levels of ALT and the decreasing rate of hepatic ALT activity and protein contents to each control group were higher in CCl4-treated rats fed HP than those fed LP. Under the animal models as indentified by the present data herein, the liver xanthine oxidase activity was higher in CCl4-treated rats fed HP than those fed LP, and the control group fed HP also showed the much higher activity xanthine oxidase than that fed LP, whereas there were no differences in the activity of hepatic aniline hydroxylase and glutathions S-transferase between the two group treated with CCl4. Although the hepatic aniline hydroxylase activity was somewhat higher in the rats fed HP than those fed LP, the increasing rate of liver xanthine oxidase to the rats fed LP was higher in those fed HP than that of liver aniline hydroxylase. The degree of liver damage identified such as liver weight and serum ALT activity was less in the CCl4-treated rats pretreated with allopurinol. These results suggest that even a system at which xanthine oxidase acts as well as the drug metabolizing enzyme may influence the acelatin of CCl4 metabolism. In addition, the purified liver xanthine oxidase from CCl4-treated rats fed HP showed decreased Km value when compared to its control group. The Km value of liver xanthine oxidase of CCl4-treated rats fed LP showed a similar Km value with its control group. Furthermore, the decreasing rate of liver and serum xanthine oxidase acitivity in CCl4-treated rats pretreated with actinomycin D to the CCl4-treated rats was higher in rats fed HP than in those fed LP. These results suggest that the inductino of xanthine oxidase in CCl4-treated rats fed HP may be greater than in those fed LP.

  • Santalum album Linn. [Family: Santalaceae] is commonly known as white sandalwood, sandal safaid and safed chandan. It is one of the most valuable trees and second costliest wood in the world. Sandalwood and its oil is extensively used in the Unani and other traditional systems of medicine as it has blood purifier, anti-inflammatory, analgesic, exhilarant, cardiotonic, antiseptic, nervine tonic and expectorant properties. It is used in skin, cardiac, liver, gastrointestinal, respiratory, integument and urogenital disorders. These uses are supported and proven by many in vitro or in vivo studies. The proven pharmacological activities of S. album are antimicrobial, anti-oxidant, anti-inflammatory, antimutagenic and anti-fatigue. The research has proven that sandal oil or its constituents have anti-microbial activity. Sandalwood oil showed skin cancer preventive effect in mice and its constituent alpha santalol showed the anticancer property. The methanolic extract of wood was confirmed for antioxidant, free radical scavenging, analgesic and anti-inflammatory activities. ${\alpha}$ and ${\beta}$ santalols present in sandal oil showed sedative effects. Sandalwood tea had a significant effect on heart muscles of frog and showed increased myocardial contractility. Its oil showed significant changes in hepatic xenobiotic metabolizing enzymes. Sandalwood oil and its major constituents showed less acute oral and dermal toxicity in laboratory animals. Hence, the aforementioned studies justify the uses of sandalwood and its oil mentioned in the classical Unani literature. However, further clinical trials are suggested to confirm its efficacy and safety in humans.

  • The protective effect of EtOAc fraction of Limonium tetragonum extract (EALT) against alcohol-induced hepatotoxicity was assessed following acute ethanol intoxication in Spraque-Dawley rats. EALT (200 mg/kg p.o.) was administrated once before alcohol intake (8 g/kg, p.o.). Blood ethanol concentration, and the activities of alcohol metabolic enzymes, alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH) in the liver were measured. Also, the formation of malondialdehyde (MDA) and the activities of antioxidant enzymes, superoxide dismutase (SOD), glutathione peroxidase (GSH-px), catalase were determined after acute alcohol exposure. Pretreatment of rats received ethanol with EALT significantly decreased blood ethanol concentration and elevated the activities of ADH and ALDH in liver. The increased MDA level was decreased, and the reduced activities of SOD, GSH-px and catalase were markedly preserved by the treatment with EALT. This study suggests that EALT prevent hepatic injury induced by acute alcohol which is likely related to its modulation on the alcohol metabolism and antioxidant enzymes activities.

  • The object of this study is to investigate the toxicity of S-biol (d-allethron-d-transchrysanthemate) and the mode of action between other synthetic pyrethroid insecticides and S-biol in rats. Rats were treated daily with S-biol (25 mg/kg, 50 mg/kg, 100mg/kg) by oral administration for 5 weeks. The experimental results were summerized as follows: Biochemical parameters such as LDH and Glucose in serum were much more increased in control groups. No significant hematological change excepts for MCHC in rats treated with S-biol 100 mg/kg were observed in all groups compared to control groups. In animals treated with S-biol for 4∼5 weeks, the levels of cytochrome P-450 in the liver were significantly increased. In renal microsomal fractions, however, no significant changes of cytochrome P-450 contents were observed. The activitis of ATPase in groups treated with S-biol (50 mg/kg, 100 mg/kg) were decreased compared to those in other groups. TBA values and activities of glucose-6-phosphatase in the liver were increased a little in the groups treated with S-biol (100 mg/kg) for 5 weeks. The activities of cholinesterase in hepatic and serum were not significantly changed in all groups but slightly decreased in animals treated with high dose of S-biol (100 mg/kg). The activities of carboxylesterase in serum and in the liver were slightly increased but not significantly changed.

  • The toxicity and histopathologic changes of diazinon (O, O-diethy-O-(2-isopropyl-6-methyl-4-pyrimidinyl)phosphorothioate) was investigated in rat. Rat was treated with diazinon (100 mg/kg/day) by oral administration for 12 days. The experimental results were summarized as follows. Biochemical parameters such as ALT, AST, LDH and glucose in serum were significantly increased and hematological parameters such as Hb, Hct and PLT in blood were slightly increased in treated groups. Also the activities of serum cholinesterase were very significantly decreased in treated groups. In the histopathological changes, the normal lobular architectural pattern of the liver was well preserved in all treated groups. However, vacuolation or fatty change were represent in hepatocytes. Sections of liver from rats treated with diazinon for 3 and 6 days contained slight lipid infiltration in the form of small droplets randomly distributed that were graded minimal (+) or moderate (++) compared with the respective control condition. After 9 days, there were numerous small and large vacuoles in the terminal hepatic venule and perilobular areas of many serial sections of these rats indicative of fatty infiltration which were graded moderate (++) and severe (+++). After 12 days, fatty infiltration progressed periportal tract areas and graded severe (+++) and very severe (++++) in experimental groups. Note absence of cellular necrosis or inflammation.
