The effects of papaverine MgCl2, cocaine, DNP, KCN and khellin on responses of some rabbit and rat tissues to CaCl2 were studied in vitro in a depolarizing medium. Guinea pig taenia coli preparation was used for comparison. In rabbit tracheal chain and vas deferens and guinea pig taenia coli preparations all spasmolytics shifted the concentration-response curves of CaCl2 to the right without affecting the maxima or slopes. In rat tracheal chain and vas deferens preparations all spasmolytics shifted the concentration-response curves of CaCl2 to the right. Furthermore all agents (except cocaine in tracheal chain preparations) depressed the maximum responses. The slopes were unaffected in either preparations. The initial competition and subsequent noncompetition observed in certain tissues is discussed in the light of the reported poor capacity of some tissues to retain Ca++ and the absence of releasable firmly bound Ca++ (11). 相似文献

Twenty-six patients under 20 years of age having cerebrovascular disease were studied from 1968 to 1972. Common risk factors such as hypertension, diabetes mellitus, hyperlipidemia and heart disease were not present. Angiographical study showed a variety of abnormalities. No consistent defect was present. There was a high incidence of pyrexia and convulsions in the early stages of stroke and it appears possible that some form of arteritis might have been important in the production of the cerebral infarction. 相似文献

OBJECTIVE: The objective of this study was to determine the prevalence of and risk factors for tuberculin skin test (TST) positivity among an industrial workforce employing many foreign-born workers after one employee was hospitalized for active tuberculosis (TB). METHODS: A contact investigation was performed. We used crude odds ratios and a multivariate model to assess risk factors for TST positivity. RESULTS: The rate of TST positivity was 37.1% (N=97). Twenty-nine of 36 (80.6%) workers from higher TB prevalence countries versus seven of 61 (11.5%) workers born in low-prevalence countries were positive. Workplace risk factors included using the lunchroom, carpooling with the case, or working on the same or subsequent shift. A total of 66.7% of immigrant workers denied previous screening. CONCLUSION: TB contact investigations should probe into workplace transmission. Workplaces with workers from higher TB prevalence countries should consider pre-placement TB screening. 相似文献
