This article deals with the organ culture on hamster trachea under the normal condition. The result showed that the epithelium of trachea could be kept alive up to 8 th-week at most by means of rotatory method of incubation. The culture media are RPMI 1640 (Nissui) and Eagle MEM (Nissui). Each medium was with or without bovine serum added. The results of histological, ultrastructural, radioautographic observations exhibited that the tracheal epithelia of hamster before culture showed ciliated columnar form with...

This article deals with the organ culture on hamster trachea under the normal condition. The result showed that the epithelium of trachea could be kept alive up to 8 th-week at most by means of rotatory method of incubation. The culture media are RPMI 1640 (Nissui) and Eagle MEM (Nissui). Each medium was with or without bovine serum added. The results of histological, ultrastructural, radioautographic observations exhibited that the tracheal epithelia of hamster before culture showed ciliated columnar form with cilia. With prolongation of culture time, the changes of tracheal epithelium took the following order, from ciliated columnar to simple columnar and to simple squamous form. These changes were observed in all 4 groups. In radioautography, there are labeling granules in nuclei of tracheal epithelial cells in all 4 groups at different culture time, indicating that the epithelial cells still maintained DNA synthetic activity. TEM observation has showed ultrastructure of tracheal epithelium remained unchanged within 4 weeks. The ciliated cells are well with intact cilia. The intercellular junction is the tight one. Occasionally in accordance with LM observation a few of ciliated cell lacked cilia and its nucleus flattened. In cytoplasm, the dilatation of cisternae of rER and the incresing amount of ribosomes and lysosomes could be seen under TEM. During 7-8 weeks only a part of epithelia of trachea was still kept well, most of them became single layer. The ciliated cells lacked cilia, and their nuclei were long and oval in shape. Some enlarged lysosomes and autophagic vacuoles could be seen in cytoplasm indicating cytoplasmic degeneration. The present study suggested that both Eagle MEM and RPMF 1640 show the same culture effect.

本文报告正常状态下金黄地鼠的体外器官培养变化。应用旋转培养方法,培养液用RPMI 1640及Eagle MEM,不论是否加小牛血清,培养的气管组织均可存活到8周。组织学及超微结构观察表明,培养1~4周内的气管上皮,保持着复层或单层柱状上皮结构,表面尚见纤毛,上皮细胞还没有明显的胞浆变性。细胞器如粗面内质网及线粒体等,还未见破坏。表层上皮细胞间的连接,也是常态的紧密连接。培养5周时,上皮表面大部分纤毛脱落,表层上皮细胞核变扁平、横位。7周以后,细胞结构出现退行性变化。放射自显影观察表明,上皮细胞核内仍有明显的~3HTdR掺入。本文认为,在一般条件下培养4周以内,气管上皮的超微结构较为完整,此时附加实验因素,开展实验病理研究是比较合适的。基础培养液Eagle MEM具有与RPMI 1640培养液相同的培养效果,无论从防止细胞增生引起培养组织的消耗,还是从经济观点考虑,在器官培养中使用基础培养液是值得推荐的。

Rat tracheal epithelial cell ( RTE) grows well in vitro under the support of 3T3 feeder cell layer. Exposure of nickel compounds results in the development of enhanced growth variant co lonies of different size and morphologies. The inducibilities of these compounds were ranked as following:Ni3S2, NiS C, NiS A, NiCl2, NiSO4, and dosely concurred with the results of animal carcingenic test. It seems that the RTE could be used as an in vitro. model for carcinogenesis studies of respiratory tract tumour and...

Rat tracheal epithelial cell ( RTE) grows well in vitro under the support of 3T3 feeder cell layer. Exposure of nickel compounds results in the development of enhanced growth variant co lonies of different size and morphologies. The inducibilities of these compounds were ranked as following:Ni3S2, NiS C, NiS A, NiCl2, NiSO4, and dosely concurred with the results of animal carcingenic test. It seems that the RTE could be used as an in vitro. model for carcinogenesis studies of respiratory tract tumour and also as a quantitative system for chemical carcinogen detection.

原代RTE细胞在3 T3滋养细胞支持下,在体外培养条件下可生长。在接受MNNG与多种镍化合物作用后,可出现恶性转化。镍化合物诱发恶性转化的能力强弱依次为Ni_3S_2、Nis(C)、NiS(A)、NiCl_2和NiSO_4,与动物诱癌试验结果一致。该系统可用于研究化学物质诱发呼吸道肿瘤的致癌过程,亦可用于定量检测化学致癌物。

Gene mutation(HGPRT and Na/K ATPase Ioccus)of V_(79) cell were inducedby nickel subsulphide,crystalline nickel sulphide,amorphous nickel sulphide,nickelchloride and nickel sulphate.The capacities of gene mutation induction were com-patible with the carcinogenic potential shown in animal test and also in theneoplastic transformation inducibility of rat tracheal epithelial cell in vitro.It sug-gests that there is close relationship between some gene mutation and thecarcinogenesis of nickel compounds and,the gene mutation assay seems to be apromising predictive system for the carcinogenic action.After exposue to nickel compounds,sister chromatid exchange(SCE)frequencieswere increased.However,the strength of SCE induction was not concordant withcarcinogenic effect.Micronucleus(MN)formation was significantly enhanced byNiSO_4,NiCl_2,and NiS A,but not by NiS C and Ni_3S_2.SCE and MN are not goodsymptoms for nickel compound carcinogenesis prediction.

Ni_3S_2,NiSA,NiSC,NiSO_4与NiCl_2等五种镍合物是具有不同致癌能力的化合物。在V_(79)细胞株基因突变试验系统中,这五类化合物能诱发HGPGT 与Na/k ATP ase 酶位点突变,其强弱程度与在动物致癌试验结果所见是一致的。提示这些镍化合物可能是通过致突变机制作用的致癌物。亦可以利用基因突变试验来预测其致癌性。这五种镍化合物可在V_(79)细胞株和SHE 细胞诱发SCE 与微核形成,但其作用强弱与其致癌能力不相一致。表明利用这类试验预测镍化合物的致癌性是不适宜的。
