AbstractErythronium japonicum (E. japonicum) and Corylopsis coreana Uyeki (C. coreana Uyeki, Korean winter hazel) have been shown to significantly decrease 1,3-dichloro-2-propanol (1,3-DCP)-induced generation of reactive oxygen species and CYP2E1 activity in HuH7, human hepatocytes. In this study, we expanded upon the previous study and investigated the effects of E. japonicum and C. coreana Uyeki extracts on 1,3-DCP-induced liver damage in rats. The pre-treatment of rats with these extracts alleviated a decrease in body weight and reduced 1,3-DCP-induced increase in catalytic activities of hepatic enzymes, such as aspartate aminotransferase and alanine aminotransferase, in the serum. Moreover, treatment with the extracts restored the 1,3-DCP-induced decreases in anti-oxidant enzyme activities, such as the activities of superoxide dismutase and catalase, in the rat liver. Histopathological studies also strongly supported the results of enzyme activities. These results suggest a possibility that the extracts of E. japonicum and C. coreana Uyeki can be a remedy for alleviating 1,3-DCP-induced liver damage in animals.

<p class="lead">In this study, puerarin derivatives were designed by adding an active acetonitrile group that inhibits cyclooxygenase-2 (COX-2) in order to enhance the anti-vascular dementia drug activity. The acetonitrile group was linked to puerarin at the 7/4 'positions by a phenolic hydroxyl to give 7-mono-and 7, 4' di-substituted derivatives of puerarin. These structures were confirmed by <sup>1</sup>H NMR spectroscopy and MS spectroscopy. We compared the affinity of puerarin derivatives and puerarin for cyclooxygenase-2 (COX-2) using molecular docking. In addition, the anti-vascular dementia activity of the developed puerarin derivatives was studied by water maze, novel object recognition, and the determination of inducible nitric oxide synthase (iNOS) enzyme activity at the cerebral cortex of mice. Experimental results showed that the puerarin derivatives have a good affinity for COX-2 with therapeutic effects against vascular dementia. The results of this study suggest that the protective effects of the puerarin derivatives against vascular dementia may be related to suppression of inflammation associated with ischemia-reperfusion injury through inhibition of COX-2.</p>

AbstractThe efficacy of humic acid (HA) as an aflatoxin (AF) binder in broiler chickens exposed to aflatoxin- contaminated feed from 1 to 42 days of age was assessed. A total of 200 birds were assigned to 20 pens, with 10 birds per pen. The following treatments (T) were applied: T1: basal diet (B); T2: B + AFB1(100 μg/kg); T3: B + AFB1(100 μg/kg) + HA (0.1%); T4: B +AFB1 (100 μg/kg) + HA (0.2%); T5: B + AFB1 (100 μg/kg) + HA (0.3%). Each treatment consisted of 4 replicates. Oxihumate was effective in diminishing the adverse effects caused by aflatoxin on body weight (BW) of broilers (P<0.05). Humic acid also showed protective effects against liver damage and some of the hematological and serum biochemical changes associated with aflatoxin toxicity (P<0.05). The supplementation of HA also enhanced the humoral immunity by counteracting the aflatoxin contamination. Results indicated that HA could alleviate some of the toxic effects of aflatoxin in growing broilers. Humic acid (0.1 to 0.3%) might, therefore, prove to be beneficial in the management of aflatoxin-contaminated feedstuffs for poultry when used in combination with other mycotoxin management practices.

The Relationship

The present study was conducted to investigate the relationship between the anti-stress and hepato-protective effects of Schisandra Lignans Extract (SLE) on stress-induced liver damage. Seven weeks old male mice were fixed in a restraint tube for 18 h to induce liver damage. SLE was orally administered to animals for 5 days at dosages of 100 and 200 mg/kg/day before exposed to restraint stress. Oral administration of SLE significantly reduced restraint-induced liver damage in experimental animal. SLE was further found to significantly alleviate the provocation of corticosterone in stressed mice. SLE also significantly decreased oxidative damage and increased anti-oxidative capability of liver cells by preventing the over production and accumulation of free radicals. In conclusion, the protective effects of SLE on stress-induced liver damage were confirmed, and the correlation between hepatoprotective and anti-stress effects of schisandra lignans was possible related to its alleviation on the malignant effects of stressors for bio-homeostasis, such as balance of oxidation and reduction in cells.
