1.The influence of the temperature of durene solution, the height from airway nozzle to liquid level, the temperature and feed rate of air on the vapor phase concentration of durene were studied with the self-made adjustor.
2.In order to develop a new method of quantitative determination of acute myocardial infarction, multiplane transesophageal three dimensional echocardiography was applied to 17 experimental dogs to measure the non perfused myocardial mass resulted from ligation of coronary artery, and the results were compared with those of Evans blue staining. It showed that the results of these two methods correlated highly with each other (?r?=0.90, ?s ?=3.8g).
3.However, there was highly distinguishable between CRD group and control group in the chronic apicalperiodontitis. ( x2=l 1.61.p<0.01),the effective rates were 76% and25% oConclusion: The result of this study manifests: the novel CRD can release a constant concentration of a therapeutic agent in the root canal for an extended period of time.
