  • A female Chinese hamster with unknown age was referred for acute onset of anorexia, depression, and large cyst from the head to body. After referring, the patient died shortly. During necropsy, severe hemorrhage in the cyst, multiple mass on liver, and transformed right kidney were found. The infection was confirmed by cytology, cultures and PCR of 16S ribosomal RNA gene. This report describes a first case of naturally occurred systemic Klebsiella oxytoca infection in a household Chinese hamster.

  • Chinese hamster, Cricetulus griseus 와 Armenian hamster, Cricetulus migratorius의 正常細胞, 腫瘍瘤에서 由來된 細胞 및 바이러스로 再形質轉換된 細胞의 乳酸데히드로게나제(LDH) 패턴을 電氣永動法에 의해 測定하여 比較하였다. 이 두 종류의 電基泳動移動度는 비슷했으며, 纖維芽細胞는 LDH-5만 나타내었고, adenovirus로 形質轉換된 上皮性인 細胞에서는 LDH-1-2-3-4-5, 2-3-4-5, 또는 3-4-5와 같은 패턴을 보여 주었다. 그러나 上皮性細胞가 自然的으로, 혹은 SV40 바이러스 處理로 因해서 纖維芽細胞로 변하였을 경우는 역시 LDH-5 패턴만 보여 주었다.

  • Objectives : We investigated genetic toxicity of HMCO5 in relation to chromosome aberration test on Cultured Chinese Hamster Lung (CHL) in the presence and absence of S-9 mix. Methods : Experimental groups were divided into two groups: with S-9mix (+S) or without S-9 mix (-S). -S group was also divided 2 series by treatment hours (6 hr: 6-S; or 24 hr; 24-S). Each group treated with vehicle only (complete culture medium), HMCO5 (1,250, 2,500, $5,000\;{\mu}g/ml$), and cyclophosphamide monohydrate (CPA) and ethylmethanesulfonate (EMS), respectively. Results : HMC05 did not show any aberrant metaphase. However, there were significant (p < 0.01) aberrant metaphases with CPA in S+ and with EMS in S-. Conclusions : These results indicate that HMC05 formula does not show any toxicity in chromosome aberration test.

  • 수종의 Aspergillus속 및 Penicillium속 균이 생산하는 진균대사 산물인 kojic acid가 독성분해 활성제의 첨가유무에 관계없이 Chinese hamster 난소세포에 염색체 변이를 일으키는 것이 확인되었다. Kojic acid 처리량의 증가에 따라 염색체 변이 또한 증가되었다. Kojlc acid의 잠재독성에 관한 본 실험결과에 기초해 이는 일종의 변이 유기체로 추정되며 현재로는 식품첨가제로서의 사용에 문제가 있는 것으로 사료된다.

  • Streptomyces caespitosus에서 分離된 抗生物質인 Mitomycin C를 Chinese hamster, Cricetulus griseus (2n=22) euploid 細胞朱인 22Emb. (♀, 20일된 embryo에서 培養한 것)과 5PSP (♂, polyoma transformed subclone)에 分量과 時間을 달리해서 處理했을 경우 일어나게 되는 特異한 染色體 異常을 觀察하였다. Mitomycin C의 分量과 處理時間 그리고 細胞朱에 따라서 染色體에 미치는 影響이 한결같지 않지만 第1, 第2 染色體의 region 5와 7, 그리고 X 染色體의 第2 收縮環(secondary constriction)에 보다 甚한 染色體 切斷을 보여 주었다. 이것은 Mitomycin C가 特히 染色體의 人形成體(nucleolar-organizar)에 關聯되어 일어나는 現象이 아닌가 생각된다.

  • The chromosomal aberration of the trichothecene mycotoxins such as T-2 toxin (T-2), HT-2 toxin (HT-2), nivalenol (NIV) and deoxynivalenol (DON) which are one of the most important food borne contaminants produced by Fusarium species fungi, was investigated in the chinese hamster lung cells. These trichothecene mycotoxins showed high cytotoxicity in order of T-2, HT-2, NIV, and DON to the chinese hamster lung cells. Nevertheless high cytotoxicity of these trichothecene mycotoxins, no clastogenicity of T-2 and HT-2 in the range of 0.01-0.0025 ng/ml, of NIV in that of 0.3-0.075ng/ml, and of DON in that of 1.0-0.25 ng/ml was observed in both with and without metabolic activation system.

  • The detection of many synthetic chemicals used in industry that may pose a genetic hazard in our environment is of great concern at present. Since these substances are not limited to the original products, and enter the environment, they have become widespread environmental pollutants, thus leading to a variety of chemicals that possibly threaten the public health. In this respect, to regulate and to evaluate the chemical hazard will be important to environment and human health. The clastogenicity of 18 synthetic chemicals was evaluated in Chinese hamster lung fibroblast cells in vitro. 4-Chloro-3,5-dimethyl phenol (CAS No. 88-04-0) induced chromosomal aberrations with significance at the concentration of 15.7 $\mu\textrm{g}$/$m\ell$ both in the presence and absence of metabolic activation system. Phenoxybenzene (CAS No. 101-84-8) which is one of the most cytotoxic chemical among 18 chemicals tested revealed no clastogenicity in the range of 0.11-0.43 $\mu\textrm{g}$/$m\ell$ both in the presence and absence of metabolic activation system. From the results of chromosomal aberration assay with 18 synthetic chemicals in Chinese hamster lung cells in vitro, 4-chloro-3,5-dimethyl phenol (CAS No. 88-04-0) revealed weak positive clastogenic results in this study.

  • To investigate the mutant induction of wild ginseng culture extract, we performed chromosomal aberration assay with chinese hamster lung cell in vitro. The test concentration of the extract was decided for the standard with the 50% suppression of cell propagation in the cell. The concentrations for the chromosome test were 1,250, 2,500 and 5,000 ㎍/ml with metabolic activation (+S, 6 hours treatment), 1,100, 2,200 and 4,400 ㎍/ml without metabolic activation (-S, 6 hours treatment) 800, 1,600 and 3,200 ㎍/ml without metabolic activation (-S, 24 hours treatment). No significant increase in chromosome aberrations was observed at any of these concentrations both in the absence and presence of metabolic activation system. Cyclophosphamide monohydrate (CPA) and ethylmethanesulfonate (EMS) caused a significant increase in chromosome aberration. These results may be concluded that wild ginseng culture extract is not capable of inducing chromosome aberration in cultured chinese hamster lung cell regardless of metabolic activation and genotoxicity of that is negative under the present experimental condition.

The clastogenicity of 11 synthetic chemicals was evaluated in Chinese hamster lung fibroblast cells in vitro. 1-Chloro-3-bromopropane CAS No. 109-70-6) induced chromosomal aberrations with significance at the concentration of $185.0\;{\mu}g/mL\;and\;1,600\;{\mu}g/mL$ both in the presence and absence of metabolic activation system, respectively. Triphenyl phosphite (CAS No. 101-02-0), which is one of the most cytotoxic chemical among 11 chemicals tested revealed no clastogenicity in the range of $95.0-4.9\;{\mu}g/mL$ both in the presence and absence of metabolic activation system. From the results of chromosomal aberration assay with 11 synthetic chemicals in Chinese hamster lung cells in vitro, 1-chloro-3-bromopropane revealed a positive clastogenic result in this study.
