The effect of Banhasasim-tang extracts on the hepatic, splenic and cardiac toxicity induced by doxorubicin administration (three injection protocol) were monitored using male ICR mice. Changes of body weight, clinical signs, necropsy findings and organ weights of liver, spleen and heart were observed with blood GOT and GPT levels. The results were as follows: 1. Decrease of body weight after doxorubicin treatment was dose-dependently inhibited by Banhasasim-tang extracts. 2. The degrees of anorexia, ataxia and dehydration that were observed in doxombicin treatment groups were dose-dependently inhibited by Banhasasim-rang extracts. 3. Increase of absolute and relative liver weight observed in the doxorubicin treatment group were dose-dependently inhibited by Banhasasim-tang extracts. In addition, the degrees of liver congestion and necrotic spot were significantly and dose-dependently decreased in the Banhasasim-rang extracts dosing group compared to that of the doxorubicin-only treatment group. It is also demonstrated that elevated serum GOT and GPT levels in the doxorubicin treatment group were significantly decreased in the Banhasasim-rang extracts dosing group. 4. Decrease of absolute and relative spleen weight observed in doxorubicin treatment groups were dose-dependently inhibited by Banhasasim-rang extracts. In addition, the degrees of splenic atrophy were significantly and dose-dependently decreased in the Banhasasim-rang extracts dosing group compared to that of doxorubicin-only treatment group. 5. Increase of absolute and relative heart weight observed in doxorubicin treatment groups were dose-dependently inhibited by Banhasasim-rang extracts. In addition, the degrees of heart congestion and enlargement were significantly and dose-dependently decreased in the Banhasasim-rang extracts dosing group compared to that of the doxorubicin-only treatment group. In conclusion, the toxicity of doxorubicin treatment (decrease of body weight, clinical signs such as anorexia, ataxia and dehydration, changes of organ weights of liver, spleen and heart, elevation of serum GOT and GPT levels) was inhibited and/or prevented by Banhasasim-rang extracts. According to these results, it is considered that Banhasasim-rang has some preventive effect against the toxicity induced by doxorubicin.

The effect of aqueous extract of Lycopus lucidus Turcz. (Labiatae)(LLAE) on mast cell-mediated immediate-type allergic reactions was investigated. LLAE (0.01 to 1 mg/g) dose-dependently inhibited systemic anaphylaxis induced by compound 48/80. LLAE (0.001 to 1 mg/g) also dose-dependently inhibited local anaphylaxis activated by anti-dinitrophenyl (DNP) IgE. When LLAE was pretreated at the same concentration with systemic anaphylaxis, serum histamine levels were reduced in a dose-dependent manner. LLAE (0.001 to 1 mg/mι) dose-dependently inhibited histamine release from rat peritoneal mast cells (RPMC) activated by compound 48/80. The level of cAMP in human mast cell line (HMC-1) cells, when LLAE (1 mg/mι) was added, significantly was increased, compared with that of normal control. These results provide evidences that LLAE may be beneficial in the treatment of allergic diseases.

We investigated the effect of aqueous extract of Terminalia chebula (Combretaceae)(TCAE) on the immediate hypersensitivity reaction in vivo and in vivo. TCAE (0.01 to 1 g/kg) dose-dependently inhibited compound 48/80 induced systemic anaphylaxis in mice. When TCAE was pretreated at concentrations ranging from 0.01 to 1 g/kg, the plasma histamine levels were reduced in a dose-dependent manner. TCAE (0.1 and 1 g/kg) significantly inhibited local immunoglobulin E (IgE)-mediated passive cutaneous anaphylactic reaction. TCAE (0.001 to 1 mg/ml) also dose-dependently inhibited the histamine release from rat peritoneal mast cells (RPMC) activated by compound 48/80 or anti-dinitrophenyl (DNP) IgE. TCAE (0.01 to 1 mg/ml) had a significant inhibitory effect on anti-DNP IgE-induced tumor necrosis $factor-{\alpha}$ production from RPMC. These results indicate that TCAE inhibits immediate hypersensitivity reaction in vivo and in vitro.

Tyrosinase (monophenol. 3.4-${\beta}$-dihydroxyphenylalanin oxygen oxidoreductase. EC 1.14.18.1 J. which plays a pivotal role in melanogenesis. It is single chain glycoprotein catalyzing the hydroxylation of tyrosine to ${\beta$\mid$$-3.4-dihydroxyphenylalanin (DOPA) and the oxidation of DOPA to DOPA quinone. To investigate whitening effect of chitosan oligosaccharide. we obtained chitosan oligosaccharide ［(glucosamine)2-6］ by NaNO2 oxidation and measured the effect of chitosan oligosaccharide on tyrosinase activity. Chitosan oligosaccharide dose-dependently inhibited tyrosinase (2 unit) activity and inhibited by 18.8% at dose of 100${\mu}$g/ml. Vitamin C. arbutin and kojic acid that are well known to be inhibitor of melanin production dose-dependently inhibited tyrosinase (2unit) activity. These results suggest that chitosan oligosaccharide may be used as inhibitor of melanin production in melanocyte. which will be further studied.

The preventive hypolipidemic effect of the aqueous extracts of Picrorrhiza Rhizoma (PR) was observed in a high fat diet (HFD) feeding hyperlipidemic mouse with their hepatoprotective effects. PR extracts (50, 100 and 200mg/kg) were orally dosed once a day for 12 weeks initiated with HFD supply, and changes on body weight and gains, liver weight, serum aspartate transferase (AST) and alanine transferase (ALT) levels were monitored with serum low density lipoprotein (LDL), high density lipoprotein (HDL), triglyceride and total cholesterol levels. The efficacy of test articles was compared to that of 10mg/kg of simvastatin (SIMVA). Dramatic decrease of both absolute and relative liver weight was dose-dependently observed in all PR extract dosing groups as compared with HFD control group. The serum AST and ALT levels were dose-dependently decreased in PR extract dosing groups. The serum LDL, triglyceride and total cholesterol levels were dose-dependently decreased in PR extract dosing groups compared to that of HFD control group. The serum HDL levels were slightly but dose-dependently increased in PR extract dosing groups as compared with control group. The efficacy on the serum lipid levels of PR extracts was slighter than that of SIMVA. Based on these results, it is concluded that water extract of PR has a relatively good favorable preventive effects on the HFD inducing hyperlipidemia and hepatopathy.

investigate action of ethanol on histamine release from rat peritoneal mast cells, we compared the inhibitory effect of ethanol with those of calcium antagonists in mechanism of between ATP and compound 48/80-induced histamine release. Ethanol dose-dependently inhibited 100 ${\mu}{\textrm}{m}$ ATP-induced histamine release, whereas did not inhibit 1 $\mu\textrm{g}$/ml compound 48/80-induced histamine release. Verapamil, TMB-8 and EGTA dose-dependently inhibited ATP-induced histamine release, but did not inhibit compound 48/80-induced histamine release. Such an inhibitory effect of calcium antagonist was similar to that of ethanol. These results suggest that the inhibitory effect of ethanol on histamine release from rat peritoneal mast cells is mediated via disturbance of calcium mobilization..
