Several parameters of ultrasonic nebulization extraction including the sample particle size, solvent volume, extraction time and ultrasonic power were studied and selected. As a result, 2.4 g of sample with particle size of 80 mesh was extracted with 15 mL of n-hexane for 20 min at an ultrasonic power of 35 W. The volatile components were analyzed by gas chromatography-mass spectrometry （GC-MS） under the optimal conditions and 57 compounds were identified. The precision, repeatability and stability of the proposed method were also studied. Compared with ultrasonic-assisted extraction（UAE） and hydrodistillation（HD） extraction, the proposed method is more efficient, faster and easier to be operated at room temperature with smaller sample and energy consumption. It is suggested that the ultrasonic nebulization extraction can be used as a novel alternative method for the extraction of volatile components from traditional Chinese patent medicine.展开更多

The experiments showed that whenatomization took place under the conditions where the combination of a pyrolytic coating graphitetube and fast raising temperature were used and the temperature was stable, the signal peak shapescould be improved, the sensitivity was enhanced, and the memory effect was removed. The vanadium infood and traditional Chinese medicinal herbs can be accurately determined using the standard curvemethod.展开更多

Method One hundred and twenty- two patients （244 eyes） were randomly divided into 3 groups. In group A （40 cases, 80 eyes）, levofloxacin hydrochloride eye drops were administrated for four times per day; in group B （42 cases, 84 eyes）, ＂heat-clearing I recipe＂ ultrasonic atomization was applied for twice per day with 20 rain for each time; and in group C （40 cases, 80 eyes）, bloodletting at EX-HN 6 was applied before ultrasonic atomization on the first 3 days of treatment, with once per day. Result （1） The total effective rate of group C was 100.00% which was significantly superior to 88.75% in group A （P〈0.05）; （2） the average course of treatment of clinical cured patients of group C was significantly shorter than those of group A and group B （P〈0.05）. Conclusion It is indicated from this study that ＂heat-clearing I recipe＂ ultrasonic atomization combined with bloodletting at EX-HN 6 in treatment of acute catarrhal conjunctivitis （fulminant wind and invading fever） have definite efficacy, its clinical efficacy is significantly superior to traditional levofloxacin treatment, and its course of treatment is obviously shorter than that of simple traditional Chinese medicine ultrasonic atomization. Cold ultrasonic atomization can effectively relieve local burning sensation, obviously relieve reddening and swelling and heat pain of patients, and ease subjective discomfort and emotional tension of patients.展开更多
