Objectives: The hepatotoxicity induced by Acetaminophen (AAP) mostly mediated by effect on oxidative stress parameters. The Zataria multiflora (Z.M) is an herbal medicine with well-known antioxidant effect. The aim of this study is investigation of preventive effects of Z.M and Carvacrol (CAR) on AAP-induced hepatotoxicity in rats. Methods: Rats were randomly divided into four groups including: 1) Control, 2) Acetaminophen (AAP), 3) and 4) CAR. The saline, Z.M (200 mg/kg) and CAR (20 mg/kg) were administrated orally for 6 days, after that AAP (600 mg/kg) was administrated in the $7^{th}$ day. Blood sampling was performed on the first and last days. Also, the liver tissue was removed for evaluation of Malondyaldehide (MDA), Thiol content, Superoxide dismutase (SOD) and Catalase (CAT). Total Protein (tPro), Glutamic Oxaloacetic Transaminase (GOT), Glutamic Pyruvic Transaminase (GPT) and Alkaline Phosphatase (ALP) in liver tissue were evaluated. The changes (${\Delta}$) of enzymes activities were presented. Results: The ${\Delta}GOT$, ${\Delta}GPT$ and ${\Delta}ALP$ in CAR group significantly decreased compared to AAP group (P < 0.01 to P < 0.001) and ${\Delta}GPT$ in Z.M group was significantly reduced in comparison with AAP group (P < 0.05). Also, MDA, Thiol, SOD and CAT levels in treated groups were attenuated compared to AAP group (P < 0.05 to P < 0.001). Conclusion: Z.M and CAR have a powerful hepatoprotective effect. CAR is more effective than Z.M. Based on the results. Z.M and CAR could be potent supplementary agents against hepatotoxicity of AAP in patients.

The purpose of this study is to investigate the protective effects of 25 herbal formulas on acetaminophen (APAP) or D-galactosamine (D-GalN)-induced hepatotoxicity in primary rat hepatocytes. Cell viability was measured using by Cell Counting Kit-8. 15 kinds of herbal formulas significantly reversed the cell viabilities of D-GalN-treated rat hepatocytes compared with D-GalN alone (p<0.05). In particular, 9 herbal formulas (Bangpungtongseong-san, Bojungikgi-tang, Galgeun-tang, Gumiganghwal-tang, Guibi-tang, Sagunja-tang, Samsoeum, Pyeongwi-san and Yijin-tang) showed the potent protective effects. However, 8 herbal formula exerted weak protective effects and 2 herbal formula did not exert effects on hepatotoxicity by D-GalN. On APAP-induced hepatotoxicity, 7 kinds of herbal formulas increased the viabilities of hepatocytes compare with APAP alone (p<0.05). These results could be provide a valuable information for the future in vivo or clinical studies to predict the hepatoprotective effects of herbal formulas.

Silymarin and curcumin have been used for supportive treatment of liver disease of difffrent etiology due to their hepatoprotective activities. The present study was carried out to investigate the hepatoprotective efffcts of silymarin and/or curcuma extract against hepatotoxins induced liver injury. To investigate hepatoprotective effects, the silymarin and/or curcuma extract were pre-treated orally to experimental animals. And thereafter a single dose of hepatotoxin, carbon tetrachloride ($CCl_4$) and acetaminophen were administered through oral or intraperitoneal route, respectively. Chronic liver damage was induced by subcutaneous injection of $CCl_4$ for 3 weeks (2 times/week). Hepatoprotective and therapeutic effects were monitored by estimating serurn ALT and AST levels and by measuring hepatic glutathione (GSH) and malondialdehyde (MDA)levels. Collagen type 1 was detected with irnrnunostaining to assess fibrosis. The results showed that the mix-ture of silymarin and curcuma extract significantly reduced serum biochemistry levels and MDA levels com-pared with those of control group in both acute and chronic animal models. In antifibrotic effect, the relative hepatic collagen content was significantly decreased by silymarin and/or curcuma extract treatment. It was concluded that the complex of silymarin and curcuma extract have a both hepatoprotective and therapeutic effect synergically in rat liver injury induced by heptotoxins.

Objectives Bogol-tang has clinically been used to protect joint cartilage and to treat osteoarthritis. Our objective was to study the protective effect of Bogol-tang extract (BGT) in functional impairment, behavioral disorders, cartilage loss and pathological changes in a monoiodoacetate (MIA)-induced murine osteoarthritis (OA) model and interleukin (IL)-$1{\beta}$ -treated primary rat chondrocytes. Methods Mouse knee joints were injected with MIA, a chemical that inhibits glycolysis and causes joint inflammation and matrix loss. MIA-OA induced mice orally administered BGT or acetaminophen (AAP) for 18 days by daily. Primary rat chondrocytes were pretreated with BGT or dexamethasone (DEX) and followed by co-incubation with IL-$1{\beta}$ (10 ng/mL). Results In MIA-OA mice model, BGT led to delayed response on hot plate analysis, and suppressed the cartilage loss and damages in joint tissues. BGT suppressed the elevated levels of inflammatory mediators, nitrite and $PGE_2$, the gene expression of matrix degrading enzymes, and extracellular-signal-regulated kinases 1/2 and c-JunN-terminal kinase phosphorylation in IL-$1{\beta}$-treated primary rat chondrocytes. Conclusions Our results suggest that BGT improve the knee joint function and delay the cartilage damages by anti-nociceptive, anti-inflammatory and ant-catabolic effects, which indicate BGT could be a potential candidate for osteoarthritis treatment.

Single oral administration to SD rats of both sexes were performed to investigate the acute toxicity of two new cough and cold remedies, WHS-1 and WHS-2. WHS-1 is composed of acetaminophen, chlorpheniramine maleate, cloperastine hydrochloride, dl-methylephedrine hydrochloride, caffein anhydrous, thiamine hydrochloride, riboflavin and serratiopeptidase. WHS-2 is composed of similar formula except that thiamine hydrochloride and riboflavin is not added. The results were as follows. $LD_{50}$ values of WHS-1 were 4295.5 mg/kg for males and 4606.3 mg/kg for females, and $LD_{50}$ values of WHS-2 were 3236.7 mg/kg for males and 4360.5 mg/kg for females. Death occurred within 2~3 hours after administration at doses up to 2900 mg/kg in WHS-1 and 2500 mg/kg in WHS-2, the main cause of deaths seemed to be respiratory disturbance. General symptoms included decreased motor activity, salivation and loss of consciousness which were commonly observed in all dead animals treated with WHS-1 and WHS-2. No significant gross finding and body weight changes were observed at any dose level in the groups treated with WHS-1 and WHS-2.
