Objectives : Cirsii Japonici Herba (CJH) is one of medicinal plants that has been frequently used for styptic purposes in Asian countries. In order to evaluate a hepatoprotective effects of CJH in the liver fibrotic diseases, the present study investigated how CJH improves a hepatic function in the dimethylnitrosamine(DMN) treated rat. Methods : CJH were orally administered to rats that has been treated with DMN. Subsequently, the amount of blood L-asparate aminotransferase (AST), L-alanine aminotransferase (ALT), and hydroxyproline were quantitated. Several histopathological markers for examining the degree of hepatic fibrosis were investigated by H-E and Masson-Trichrome staining. Results: DMN treatment caused a increase of relative liver weight to the body at 14 days after DMN induction, Administration of CJH with 100mg/kg and 1,000mg/kg dose decreased significantly the AST level elevated by DMN injection(p<0.01). But ALT level was not improved. The hydroxyproline level was reduced by a simultaneous treatment of CJH with DMN for 7 days, but not recovered completely to its normal value, CJH administration improved conspicuously the DMN-induced histopathological changes of liver such as granuloma, but cell necrosis and fibrosis were not improved with CJH 1,000mg/kg dose. Conclusion: These results indicate that CJH has protective effect on liver injury and can inhibit liver fibrosis Induced by DMN in rats.

Summary: We report the first hepatic adverse effect of tosufloxacin tosylate in a muscle invasive bladder cancer patient with normal liver functions and with scheduling to undergo a surgical operation for a neobladder. Tosufloxacin tosylate 150 mg was administered to a 57-year-old man who maintained transurethral resection of bladder tumor (TUR-BT) postoperative multiple medications. His labs presented significant increases in alanine amino transferase (ALT) and aspartate amino transferase (AST) levels with 2-week compliance of 150 mg tablet three times a day. After discontinuing tosufloxacin tosylate, the levels slowly decreased and completely returned to normal ranges without any intervention in a few weeks. The Naranjo Causality Algorithm indicates a probable relationship between increased ALT and tosufloxacin. The patient was to have the second surgical operation as scheduled after getting normal range of ATL level. Therefore, tosufloxacin should be avoided in patients at risk for having liver dysfunctions or diseases if the patients have a schedule for any operation. Background: Tosufloxacin tosylate has been shown to have favorable benefits as an antibiotic. Tosufloxacin tosylate may be considered to have the adverse effects such as nauseas, vomiting, diarrhea, abdominal pain, stomatitis, tendonitis, tendon rupture, headache, dizziness, drowsiness, insomnia, weakness, agitation including hemolysis in the event of glucose-6-phosphate dehydrogenase deficiency as other fluoroquinolones. More severe adverse reactions of tosufloxacin tosylate over the above common adverse effects of fluoroquinolones were thrombocytopenia and nephritis. It also is not well known that tosufloxacin can cause hepatic problem. Here the study reports the first hepatic reaction from tosufloxacin and might arouse heath care providers' attention to appropriate drug choice for patients.

Anticonvulsant hypersensitivity syndrome is a rare but fatal complication. It manifests as fever, skin rash, lymphadenopathy, and hepatitis. Phenytoin, phenobarbital, and carbamazepine are the most frequently involved drugs. We here report a case of phenytoin-induced anticonvulsant hypersensitivity syndrome. A 37-year-old woman presented with fever and generalized skin rash, 3 weeks following commencement of phenytoin 400mg daily for treatment of seizure after superficial temporal artery-middle cerebral artery(STA-MCA) anastomosis for moyamoya disease. Her temperature was $39.3^{\circ}C$ and her face was edematous. Laboratory findings showed elevated hepatic enzymes and eosinophilia. Blood and urine culture were all negative. Initially, prednisolone was commenced at 30 mg daily. But fever and skin rash did not improved and hepatic function was more aggravated. After increasing dose of steroid(methylprednisolone 125mg/day), fever and skin rash disappeared and hepatic enzymes returned to normal range.

It has been hypothesized that formation of oxygen-derived free radicals may play an important part in ischemically induced tissue injury. In this study, the effects of vitamin C treatment on hepatic reperfusion model were investigated. Livers isolated from 18 hrs fasted rats were subjected to low flow hypoxia (1 $m\ell$/g liver/min, for 45min) followed by reoxygenation (for 30min). The perfusion medium used was Krebs-Henseleit bicarbonate buffer (KHBB, pH 7.4) and vitamin C (0.25, 0.5, 1.0 and 2.0 mM) was added to perfusate. 7-Ethoxycoumarin was used as substrate of phase and metbolism. After hypoxia oxygen consumption significantly dropped but vitamin C 0.25, 0.5 and 1.0 mM treatments restored oxygen consumption to the level of control group. LDH and lipid peroxidation were not changed in all experimental groups. Oxidation, phase metabolism, significantly decreased following hypoxia but improved during reoxygenation. Vitamin C 0.25 mM treatment significantly improved the oxidation of 7-ethoxycoumarin during hypoxia and reoxygenation, but the oxidation significantly decreased by vitamin C 2.0 mM treatment. Similarly, sulfate conjugation decreased in hypoxic group, but this decrease was inhibited by vitamin C 0.25, 0.5 and 1.0 mM treatments. Our findings suggest that hypoxia/reoxygenation diminishes hepatic drug metabolizing function, vitamin C at concentration of 0.25-1.0 mM ameliorates but at higher concentration aggravates these hypoxia/reoxygenation-induced changes.

The glial fibrillary acidic protein (GFAP) is traditionally used as a marker for astrocytes of the brain, and more recently for the hepatic stellate cells (HSCs) of the liver. Several GFAP splice variants have been previously reported in the astrocytes of the CNS and in the non-myelinating Schwann cells of the PNS. In this study, we investigate whether GFAP splice variants are present in the HSCs and their expression as a function of HSCs activation. Furthermore, the regulation of these transcripts upon treatment with interferon gamma ($IFN-{\gamma}$) will be explored. Using semi-quan-titative RT-PCR and real-time PCR, we examine the expression and regulation of GFAP splice variants in HSCs as well as their respective half-life. We discover that most of the GFAP splice variants ($GFAP{\alpha}$, ${\beta}$, ${\delta}$, ${\varepsilon}$ and $\kappa$) found in the neural system are also expressed in quiescent and culture-activated primary HSCs. Interestingly, $GFAP{\alpha}$ is the predominant form in quiescent and culture-activated primary HSCs, while $GFAP{\beta}$, predominates in the SV40-immortalized activated HSC-T6. $GFAP{\delta}$, ${\varepsilon}$ and ${\kappa}$ have similar half-lives of 10 hours, while $GFAP{\beta}$ has a half-life of 17 hours. Treatment of HSC-T6 with $IFN-{\gamma}$ results in a significant 1.29-fold up-regulation of $GFAP{\alpha}$ whereas the level of the other transcripts remains unchanged. In summary, $GFAP{\alpha}$, ${\beta}$, ${\delta}$, ${\varepsilon}$ and $\kappa$ are present in HSCs. They are differentially regulated on the transcription level, implying a role of the 5' and 3' untranslated regions.

Background: Alcoholic steatosis is the earliest and most common liver disease, and may precede the onset of more severe forms of liver injury. Methods: The effect of Korean Red Ginseng extract (RGE) was tested in two murine models of ethanol (EtOH)-feeding and EtOH-treated hepatocytes. Results: Blood biochemistry analysis demonstrated that RGE treatment improved liver function. Histopathology and measurement of hepatic triglyceride content verified the ability of RGE to inhibit fat accumulation. Consistent with this, RGE administration downregulated hepatic lipogenic gene induction and restored hepatic lipolytic gene repression by EtOH. The role of oxidative stress in the pathogenesis of alcoholic liver diseases is well established. Treatment with RGE attenuated EtOH-induced cytochrome P450 2E1, 4-hydroxynonenal, and nitrotyrosine levels. Alcohol consumption also decreased phosphorylation of adenosine monophosphate-activated protein kinase, which was restored by RGE. Moreover, RGE markedly inhibited fat accumulation in EtOH-treated hepatocytes, which correlated with a decrease in sterol regulatory element-binding protein-1 and a commensurate increase in sirtuin 1 and peroxisome proliferator-activated receptor-a expression. Interestingly, the ginsenosides Rb2 and Rd, but not Rb1, significantly inhibited fat accumulation in hepatocytes. Conclusion: These results demonstrate that RGE and its ginsenoside components inhibit alcoholic steatosis and liver injury by adenosine monophosphate-activated protein kinase/sirtuin 1 activation both in vivo and in vitro, suggesting that RGE may have a potential to treat alcoholic liver disease.

The effects of Aegle marmelos (Rutaceae) leaf, Emblica officinalis (Euphorbiaceae) fruit and Ocimum sanctum. (Labiateae) leaf extracts were studied in L-thyroxine (0.5 mg/kg) induced hyperthyroidic mice. Separately combined effects of these three plant extracts and of a commonly used antithyroidic drug, Propyl thiouracil (PTU) were investigated for comparison. Serum concentration of thyroxine $(T_4)$, triiodothyronine $(T_3)$, glucose and the activity of hepatic Glucose 6-Phosphatase (G-6-Pase) were considered as main parameters. Hepatic lipid peroxidation (LPO), superoxide dismutase (SOD) and Catalase (CAT) activities were also studied to reveal the toxic effect of the plant extracts, if any. While exogenous $T_4$ enhanced serum concentration of $T_4$, $T_3$, glucose and the activity of hepatic G-6-Pase, a simultaneous administration of either A. marmelos leaf (1.0 mg/kg), E. officinalis fruit( 30 mg/kg) and O. sanctum leaf (50 mg/kg) extracts, to hyperthyroidic animals decreased all these parameters. However, the effects were more pronounced, as nearly normal thyroid function and serum glucose concentration were exhibited when all three plant extracts were administered together. A decrease in LPO and a concomitant increase in SOD and the CAT activities indicated the safe and antiperoxidative nature of the plant extracts, administered either alone or in combination. Our findings reveal that the three test plant materials exhibit synergistic effects without any hepatotoxicity, suggesting their potential use in the amelioration of hyperthyroidism and/ or hyperglycaemia.
