燒伤后容易引起局部感染者为绿脓桿菌,此菌对大多数抗菌素具有抗药性,为进一步寻找抗綠脓桿菌的有効药物,从具有特殊消毒作用、抗真菌作用及常用于抗菌方面的中药中选出14种进行了筛选和比較。1.浸液的制备: 取中药研成粗粉。用50%醇浸渍20小时,浸液濾过,回收醇,制成1毫升約合原来生药0.5克的原液。2.制菌試驗: 將从燒伤病人膿性分泌物中分离出的绿膿桿菌,接种于含有1毫升中药浸液和1毫升普通琼脂所制得的斜面培养基上进行制菌試驗,結果如右表:
After infection, Pseudomonas aeruginosa is the most likely cause of local infection. This strain is resistant to most antibiotics. It is an effective drug for P. aeruginosa and has special antiseptic, anti-fungal and anti-bacterial properties. Fourteen of them were selected and compared. 1. Preparation of extract: Take Chinese medicine into coarse powder. After impregnating with 50% alcohol for 20 hours, the solution was filtered and the alcohol was recovered to make 1 ml of a stock solution containing about 0.5 g of the original crude drug. 2. Straining test: Pseudomonas aeruginosa isolated from purulent secretions of burn patients was inoculated on slant culture medium containing 1 ml of Chinese medicine infusion and 1 ml of common agar for bacteriostatic test. The results are shown in the table to the right
