Objectives: Terminalia chebula, the main ingredient of Altan Arur 5, has been used for many years in traditional medicine. This medicine is more effective than other drugs and is used to treat chronic gastritis and gastrointestinal disorders such as peptic ulcers and esophageal reflux. Other ingredients of Altan Arur 5 are Punica granatum (pomegranate), tulip seeds, black balm, and excreta of Trogopterus xanthipes. The main ingredients of T. chebula are antibacterial and analgesic in traditional medicine. Despite having been used for many years and although many studies have been conducted on the beneficial effects of this medicine and its ingredients, the toxicity of Altan Arur 5 has not yet been elucidated. Therefore, we aimed to study the toxicity of Altan Arur 5 to ensure that it is safe to use. Methods: Acute and chronic toxicity of Altan Arur 5 were assessed in 10 Kunming mice and 8 Sprague-Dawley rats, respectively, in different doses. In the acute toxicity study, Altan Arur 5 was orally administered to Kunming mice in doses of 12 g/kg, 24 g/kg, and 48 g/kg for 14 days. In the chronic toxicity study, it was orally administered to Sprague-Dawley rats in doses of 1.25 g/kg, 2.5 g/kg, and 5 g/kg for 12 weeks. Results: No significant differences were observed in the relative organ weights for mice treated with Altan Arur 5 compared with those in the control group. Furthermore, no macro- or microstructural changes were noted in the organs of any group. Conclusion: Our toxicity testing revealed that the traditional medicine Altan Arur 5 has no toxic effects in vivo.

Ohjuksan has been used for the treatment of cold and pantalgia in traditional medicine. The anti-inflammatory activity of the aqueous extract from Ohjuksan (OJSE) was investigated utilizing acetic acid-induced edema and adjuvant arthritis in rats. The effects of this agent on acute toxicity and acetic acid-induced writhing syndrome in mice were also examined. OJSE did not showed acute toxicity at 2400mg/kg (p.o.) and 1200mg/kg(i.p.) body weight. It was also showed to have significant analgesic action on the writhing syndrome in mice induced by 0.7% acetic acid at 300,600mg/kg body weight. It showed anti-inflammatory activity in 5% acetic acid-induced edema and adjuvant arthritis with oral administration in rats and exhibited significant preventive effect on edema at 300 and 600mg/kg(p<0.01). In the method of adjuvant arthritis, orally administered for 19 days, it inhibited the hind paw edema in rats with 300 and 600 mg/kg body weight from 5 th day to 19th day. These results suggest that OJSE had analgesic and anti-inflammatory action.

As part of our search for less toxic antimicrobial agents from natural resources, antimicrobial activity of rutin isolated from Sophora japonica was tested in vitro against four kinds of gram positive bacteria and four kinds of gram negative bacteria by serial broth dilution method. Among eight kinds of bacteria tested, the antimicrobial activity of rutin was the most potent against Mycobacterium smegmatis showing MIC of $375\;{\mu}g/ml$. The acute toxicity of rutin was examined in mice and rats. and $LD_{50}$ value administered intraperitoneally in mice was 650 mg/kg(Confidence limit: 894-1,473 mg/kg). There were no significant changes in serum biochemical values and histopathological changes as compared with those of control after intraperitoneal administration with rutin in rats.

This study was conducted to obtain acute information of the oral dose toxicity of lyophilized water extract of Pinelliae Rhizoma, a dried tuber of Pinellia ternata (PR) in male and female mice. In order to calculated 50% lethal dose (LD$_{50}$) and approximate lethal dose (ALD), test material was once orally administered to male and female ICR mice at dose levels of 2000, 1000, 500, 250, 125 and 0 (vehicle control) ml/kg (body weight). The mortality and changes in body weight, clinical signs, gross observation, organ weight and histopathology of principle organs were monitored 14 days after treatment with PR extract. We could not find any mortalities, clinical signs, changes in the body and organ weights, gross and histopathological findings except for dose-dependent increases in the hepatic fatty change frequencies detected in PR extract 2000 and 1000mg/kg treated in both male and female mice. The results obtained in this study suggest that LD$_{50}$ and approximate LD in mice after single oral dose of PR extracts were considered over 2000 mg/kg in both and female male mice, but more than 1000mg/kg of PR extracts treatment could induce slight hepatotoxicity the fatty changes in mice.

6-[(N-3,4-Dibromophenyl)amino]-7-chloro-5,8-quinolinedione(FCK13) was tested for antifungal activities. The MIC values were determined by the two-fold dilution method. The therapeutic potential of RCK13 had been assessed in comparison with ketoconazole and fluconazole against systemic infections with candida albicans in normal mice. RCK13 had ED50,0.80$\pm$0.21 mg/kg but ketoconazole had ED50, 8.00$\pm$0.73 mg/kg respectively. And administered RCK13 at the ED50 for 14 days improved survival rates as well as ketoconazole. Acute oral toxicity studies of RCK13 were carried out in ICR mice of both sexes. These acute oral toxicities of RCK13 were low and LD50 values were over 2,850 mg/kg in ICR mice. The genotoxicities of RCK13 had been evaluated. RCK13 was negative in Ames test with Salmonella typhimurium and chromosomal aberration test in CHL cells. The clastogenicity was tested on the RCK13 with in vivo mouse micronucleus assay. RCK13 did not show any clastogenic effect in mouse peripheral blood and was negative in mouse micronucleus assay. These results indicate that RCK13 has no genotoxic potential under these experimental conditions.

It has been reported that 50~70% of child asthma, bronchial asthma in adult, and allergic rhinitis are caused by house dust mite. The antigen extracted from house dust mite has been used for effective treatment against allergic diseases and for clinical test. This house dust mite antigen has been entirely imported from abroad. However, the composition and content of all the antigen imported vary from a brand to other brand. Thus, we need to standardize the composition and content of the antigen by developing it domestically. We proceeded pre-clinically general pharmacological test and toxicological test that are required for the eventual human use by utilizing the house dust mite cultured in Korea. In order to obtain information on general pharmacological tests such as its toxic signs in tissues or organs which are mainly affected, we examined the effect of house dust mite on the tensions of the isolated tissues and heart rates of cardiac muscle by recording with force displacement transducer of polygragh (Glass Model 7). We determined lethality of antigen extracted from house dust mite in mice and guinea pigs. We examined acute and subacute toxicity by administrating house dust mite extract of 500, 100, 20 times of the expected clinical dose. In male and female mice and guinea pigs, given a sigle intraperitoneal dose of antigen, $LD_{50}$ values were over 5.0 $\textrm{m}{\ell}$/kg, respectively. In animals administrated with house dust mite, there were no significant change of clinical symptom, body weight, food consumption, water consumption, eye examinations, urinalysis, blood biochemistry, and histopathological examinations in any animals tested. We found no toxic effect of this house dust mite. These results show that the house dust mite cultured by us could be used in the development of medicine against allergic diseases caused by the antigen of house dust mite.

CJ50001 is a recombinant human granulocyte colony-stimulating facto, (rHuG-CSF) that stimulates the formation of neutrophils from bone marrow stem cells. It was produced in E. colt and purified through refolding and several processes. We produced CS970125(300) using purified C150001 and additives in order to test the stability of CJ50001. When CS970125(300) was stored at 50'S for more than 1 week, high molecular weight proteins were formed and those proteins were detected by non-reducing SDS-PAGE, gel filtration HPLC, and Western blot. Those proteins showed single band at the same position of CJ50001 in reducing SDS-PAGE. These data indicated that those high molecular weight proteins were the multimers of C150001. In biological assays, iu viro and in viro, the multimers did not have biological activity and inhibitory action to that of CJ 50001. The mutimers did not induce toxicity in mice and rats in acute toxicity test. These results suggest that if Cs970125(300) containing CJ50001 is stored at 5$0^{\circ}C$, CJ50001 will be the multimers that do not have biological activity and inhibitory effect to CJ50001 and do not induce acute toxicity.
