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.

The cytotoxic activities of Pinellia ternate, Aconitum carmichaeli, Arisaema amurense, Aconitum kusnezoffii and Scutellaria baicalensis on monkey kidney cell (Vero) and human liver cell (WRL68) were evaluated by Sulforhodamine B Protein (SRB) and Tetrazolium-based (MTT) colorimetric assay methods The results were as fellows : 1 The Pinellia ternate and Arisaema amurense did not show the cytotoxic activities at any concentration without processing or natural drugs. 2 The extracts of Aconitum carmichaeli, Aconitum kusnezoffii and Scutellaria baicalensis showed cytotoxic activities. However, the cytotoxic activities of processing drugs were less effective than the natural drugs. 3. The cytotoxic activities on monkey kidney cell (Vero) and human liver cell (WRL68) of Aconitum carmichaeli was determined by MTT assay. The Kyungpo(京?) of Aconitum carmichaeli showed less concentrate than that of the Dangpo(唐?). The $IC_{50}$ value on monkey kidney cell (Vero) and human liver cell (WRL68) of Kyungpo was $937{\pm}29\;and\;731{\pm}31{\mu}g/ml$, respectively 4. The cytotoxicity on monkey kidney cell (Vero) and human liver cell (WRL68) of Scutellaria baicalensis showed strong activities without processing or natural drugs.

In this study, we investigated whether adenosine, adenine, uridine and homogentisic acid derived from Pinellia ternata affect the secretion, production and gene expression of MUC5AC mucin from airway epithelial cells. Confluent NCI-H292 cells were pretreated with adenosine, adenine, uridine or homogentisic acid for 30 min and then stimulated with PMA (phorbol 12-myristate 13-acetate) for 24 h. The MUC5AC mucin gene expression, mucin protein production and secretion were measured by RT-PCR and ELISA, respectively. The results were as follows: (1) Adenine and homogentisic acid decreased PMA-induced MUC5AC mucin gene expression, although adenosine and uridine did not affect the mucin gene expression; (2) Adenosine, adenine, uridine and homogentisic acid inhibited PMA-induced MUC5AC mucin production; (3) Homogentisic acid inhibited the secretion of MUC5AC mucin from NCI-H292 cells. These results suggest that, among the four compounds examined, homogentisic acid showed the regulatory effect on the steps of gene expression, production and secretion of mucin, by directly acting on airway epithelial cells.

A mouse whole animal bioassay was employed to screen for potential mutagenicity of ethanol/water extracts of 16 Chinese herbal drugs that are commonly prescribed in Korea. Specific cytogenetic toxicity was measrured by recording evidence of clastogenesis toxicity was measured by recording evidence of clastogenesis via the mouse bone marrow micronucleus test. Male ICR mice administered ethanol extract of Pinelliae tuber (Pinellia eternata Breitenbach, ARACEAE, 양복) and ddY female mice administered extract of Angelica Koreanae radix(Angelica Koreana Maximowicz, UMBELLIFERAE, ) (both by oral administration, at a dose of 600 mg/kg), in a short-term dosing schedule, demonstrated significant increase in micronucleated polychromatophilic erythrocytes, indicating the increase of clastogenicity.

반하의 기내 조직배양을 통해 소괴경 생산을 하고자 적합한 식물생장조절제 처리조건, 배지와 처리 농도, 고형지지물의 종류와 농도를 조사하였다. 기내 소괴경 형성에 적합한 식물생장조절물질과 농도 조건을 연구 한 결과 0.1mg/l 2,4-D와 0.5 mg/l BAP 혼합처리에서 잎 (3.9개)과 엽병 (4.7개) 배양모두 최고치의 소괴경을 생산할 수 있었다. 기내 소괴경 형성에 적합한 배지는 SH배지로 나타났으며 잎과 엽병 배양에서 4.5와 5.2개의 소괴경을 생산하였으며, 최적 농도는 SH 배지의 무기염류를 반으로 줄인 1/2 SH배지가 가장 효과적이었다. 기내 소괴경 생산에 적합한 고형지지물과 그 농도를 조사한 결과, 잎과 엽병 배양 모두 agar보다 gelrite에서 소괴경 형성이 잘 되었으며, 농도별로는 agar 6%, Gelrite는 4% 처리에서최고치의 소괴경을 생산할 수 있었다. 기내에서 생산된 소괴경은 5$^{\circ}$C에서 1개월간 냉장 보관 후에 생장상에서 MS 고형배지가 든 배양용기와 멸균 소독한 상토에 옮겨 발아율을 조사한 결과, MS고형 배지에서 자란 소괴경은 86%의 발아율을 보였으며, 멸균 소독한 상토에서는 43%의 발아율을 보였다. 추후 반하 소괴경의 발아율과 토양 적응성을 높이는 연구보강으로 소경을 번식용 종자로 활용할 수 있는 방안을 모색할 예정이다.

Brevibacillus brevis GZDF3 is a gram-positive, plant growth-promoting rhizosphere bacterium (PGPR) isolated from the rhizosphere soil of Pinellia ternata (an important herb in traditional Chinese medicine). The GZDF3 strain produces certain active compounds, such as siderophores, which are the final metabolite products of non-ribosomal peptide synthetase (NRPS) and independent non-ribosomal peptide synthetase (NIS) activity. With the present study, we attempted to investigate the siderophore production characteristics and conditions of Bacillus sp. GZDF3. The antibacterial activity of the siderophores on pathogenic fungi was also investigated. Optimal conditions for the synthesis of siderophores were determined by single factor method, using sucrose 15 g/l, asparagine 2 g/l, 32℃, and 48 h. The optimized sucrose asparagine medium significantly increased the production of siderophores, from 27.09% to 54.99%. Moreover, the effects of different kinds of metal ions on siderophore production were explored here. We found that Fe³⁺ and Cu²⁺ significantly inhibited the synthesis of siderophores. The preliminary separation and purification of siderophores by immobilized-metal affinity chromatography (IMAC) provides strong antibacterial activity against Candida albicans. The synergistic effect of siderophores and amphotericin B was also demonstrated. Our results have shown that the GZDF3 strain could produce a large amount of siderophores with strong antagonistic activity, which is helpful in the development of new biological control agents.

This study was carried out to research antimicrobial agents from medicinal plants, Lonicera japonica, Pinellia ternata, Dictamnus albus, Cryptotympana pustulata, Pinus densiflora, Bupleurum falcatum, Forsythia saxatilis, Castanea crenata, Hovenia dulcis, Prunus sargentii. The ethanol extracts of 10 medicinal plants were tested for the antimicrobial activity against Streptococcus mutans. The extracts of Pinus densiflora showed significant antimicrobial activity against Streptococcus mutans. These results suggested that the extract from Pinus densiflora could be a candidate for new antimicrobial agents against Streptococcus mutans.
