【摘要】 本文研究了Coxsackie B₂病毒（XOX B₂V）对人及鼠心肌细胞的感染性以及三氯化铬对心肌细胞生长与对病毒感染佳的影响。实验结果证明人心肌细胞对COX B₂ V感染的敏感性比鼠心肌细胞高。三氯化铬能促进人与鼠心肌细胞的生长,促进鼠心肌细胞的搏动及搏动频率加快,并随着培养时间的增加,细胞生长代谢旺盛,细胞培养液中乳酸脱氢酶（LDH）的含量升高。用含铬培养液培养的人心肌细胞对病毒感染的敏感性有所降低,人心肌细胞培养液中LDH的含量随病毒对细胞损伤的程度而升高。更多还原

【Abstract】 In this paper, we studied the infeetivity of Coxsackie B₂ Virus（Cox B₂ V） on human and rat myocardial cells （HMC and RMC） and the effect of chromium chloride（CrCl₃） on growth heart cells and infectivity of the virus.Results indicated that HMC is more sensitive to the virus than RMC. Crcl₃ could promote the grawth and pulsation of HMC and RMC.LDH studies of the cuhure cells revealed that:1. In cultured RMC treated with CrCl₃, lactodehydrogenase （LDH） increased with the time of incubation.2. Sensitivity of the cultured cells treated with CrCl₃ to Cox B₂V decreased.3. In cultured HMC, LDH increased with the degree of CPE.更多还原
