ABSTRACT
Objective: To establish a method for the determination of fractal dimension of ethanol precipitation flocs in two kinds of root medicinal herbs (Astragali Radix and Isatidis Radix). Method: The ethanol-precipitated flocs of Astragali Radix and Isatidis Radix were taken as the research objects. Firstly, the original microscopic images of the ethanol precipitation flocs were binarized by Ostu algorithm. Secondly, the influence of sampling volume, dilution multiple, image magnification ratio and number of image acquisition sites on fractal dimension was investigated using perimeter-area method. Result: The ethanol precipitation flocs of Astragali Radix and Isatidis Radix had fractal characteristics. At the same time, the stable and reliable fractal dimension of the flocs could be obtained when the sampling volume was 600-800 μL, the sample was diluted to 5-20 times, the microscopic image was enlarged to 200 times or 400 times, and four different image acquisition sites were selected. Conclusion: The established method is stable and feasible, which can provide reference for the fractal theory of ethanol precipitation flocs of root medicinal herbs.
ABSTRACT
<p><b>OBJECTIVE</b>To probe into an effective injection way of Morphine for treatment of chest pain of acute cardiac infarction.</p><p><b>METHODS</b>Ninety cases of myocardial infarction were randomly divided into 3 groups, an acupoint-injection group, an intravenous injection group and a hypodermic injection group, 30 cases in each group. The acupoint-injection group were treated with injection of 2 mg Morphine into bilateral Neiguan (PC 6) respectively, and the intravenous injection group with intravenous injection of 5 mg Morphine and the hypodermic injection group with hypodermic injection of 5 mg Morphine, and other treatments were same in the 3 groups. The analgesic effects were assessed with visual analogue scale (VAS) 5, 10, 30, 60 and 180 minutes after treatment and the complications were observed.</p><p><b>RESULTS</b>There were no significant differences among the 3 groups before treatment in the VAS score (P > 0.05). The analgesic effect in the acupoint-injection group was better than those in other two groups 5 min, 30 min and 180 min after treatment (all P < 0.01). The incidence rate of nausea and vomiting of 0.3% in the acupoint-injection group was significantly lower than 40.0% in the intravenous injection group and 20.0% in the hy podermic injection group (all P < 0.01).</p><p><b>CONCLUSION</b>Injection of small dose of Morphine into Neiguan (PC 6) has a definite therapeutic effect on chest pain of acute myocardial infarction with earlier analgesic effect, smaller dose of Morphine, longer analgesic duration and less complications.</p>

<p><b>OBJECTIVE</b>To study the on effects of anti-bacteria, anti-inflammatory and pyretolysis of Oxalis griffithii, it is possible safety.</p><p><b>METHOD</b>The mice model was established by xylene (auricle smear method) and carrageenin (injection under the aponeuroses) respectively, rat febrile model was builded by 2,4-dintrophenol injection, and observe the effects of anti-bacteria in vitro that contracted by Staph aureus, Escherichia, Shigella, Pseudomonas, Aeruginosa. The mice model of experiment study on urgent poison effects (injection under the aponeuroses).</p><p><b>RESULT</b>It was found that the mouse ear edema induced by xylene, the increased vascular permeability caused by xylene were all significantly suppressed by Oxalis griffithii. At the same time, it could depressed the rat fervescence by 2,4-dinitrophenol. In addition, it has effect on fighting against Escherichia coli in cavum abdominis of mice. Oxalis griffithii hasn't canker affect.</p><p><b>CONCLUSION</b>These results suggested that Oxalis griffithii had the effects of antinflammatory, pyretolysis, and safety.</p>
