METHODS： Thirty healthy dogs were divided randomly into five groups （n = 6 in each group）, namely control, oleanolic acid tablet （OAT）, O3, YC and O3 ＋ YC, given either no particular pre-treatment, oral OAT, medical ozone rectal insulfflation every other day, oral YC, or oral YC plus medical ozone rectal insulfflation every other day, respectively, for 30 consecutive days. After pre-treatment, acute hepatic injury was induced in all dogs with a single-dose intraperitoneal injection of CCh. General condition and survival time were recorded. The biochemical and hematological indexes of alanine aminotransferase （ALT）, aspartate aminotransferase/ alanine aminotransferase （AST/ALT）, serum total bUirubin （TBIL）, prothrombin time （PT）, blood ammonia （AMMO）, and blood urea nitrogen （BUN） were measured after CCh injection. Hepatic pathological changes were also observed.RESULTS： Compared to the other four groups, the changes of group O3 ＋ YC dogs＇ general conditions （motoricity, mental state, eating, urination and defecation） could be better controlled. In group O3 ＋ YC the survival rates were higher （P 〈 0.05 vs group control）. AST/ALT values were kept within a normal level in group O3 ＋ YC. Hepatic histopathology showed that hepatic injury in group O3 ＋ YC was less serious than those in the other four groups.CONCLUSION： Medical ozone combined with TCM YC could exert a protective effect on acute liver injury induced by CCI4,展开更多

METHODS: ALI was successfully induced by injecting carbon tetrachloride (CCl4) intra peritoneally and by tail vein injection of Bacillus Calmette Guerin (BCG) and lipopolysaccharide (LPS) in mice, respectively. Each of the two model groups was divided into normal group, model group, FFHQ (60, 120 and 240 mg/kg) treatment groups, and bifendate treatment group. At the end of the experiment, levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST), content of malondialdehyde (MDA), activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-px) in liver homogenate were measured by biochemical methods. The activities of tumor necrosis factor-α (TNF-α) and interleukin-1 (IL-1) were determined by radio-immunoassay. Hepatic tissue sections were stained with hematoxylin and eosin and examined under a light microscope. RESULTS: In the two models of ALI, FFHQ (60, 120, 240 mg/kg) was found to significantly decrease the serum transaminase (ALT, AST) activities. Meanwhile, FFHQ decreased MDA contents and upregulated the lower SOD and GSH-px levels in liver homogenate. Furthermore, in immunologic liver injury model, FFHQ decreased levels of TNF-α and IL-1 in serum. Histologic examination showed that FFHQ could attenuate the area and extent of necrosis, reduce the immigration of inflammatory cells. CONCLUSION: FFHQ had protective effect on liver injury induced by either CCl4 or BCG+LPS in mice, and its mechanisms were related to free radical scavenging, increasing SOD and GSH-px activities and inhibiting the production of proinflammatory mediators.展开更多
