Antifungal Activity of Extracts from Clerodendrum Bungei Leaves against Two Species of Phytopathogens

The test was undertaken to reveal the antifungal activity of extracts from Clerodendrum bungei leaves against Pestalotia and Rhizoctonia solani, the results showed that optimal condition for best antifungal activity of extracts against pestalotia and Rhizoctonia solani are as follows： material-liquid ratio of 1：6,75% ethanol as extracting solvent, reflux at 90℃ for 1.5 h. The substances with good dissolubility in ethanol and water solution such as organic acid, bioflavonoid and alkaloid are main antifungal bioactive substances in Clerodendrun bungei.

丹溪玉屏风颗粒联合纳他霉素治疗真菌性角膜炎的临床效果观察

目的:观察丹溪玉屏风颗粒联合纳他霉素治疗真菌性角膜炎的临床效果。方法:纳入我院眼科2014年1月至2015年4月收治的真菌性角膜炎患者80例,随机双盲地将患者分为观察组和对照组各40例,对照组给予纳他霉素治疗,观察组给予丹溪玉屏风颗粒联合纳他霉素治疗。记录治疗前患者相关指标,并对治疗后两组患者相关指标进行对比分析。结果:观察组患者治疗后视力指数和角膜溃疡直径分别为(0.45±0.04、1.90±0.21mm),均明显优于对照组(0.38±0.03、2.68±0.30mm)。观察组患者治疗后角膜溃疡消失时间、前房积脓消失时间、畏光流泪消失时间和异物感消失时间分别为(15.46±2.08、14.92±2.16、18.38±2.01、14.93±1.94)d,均明显优于对照组(20.96±3.46、19.86±3.82、22.73±3.01、18.84±2.93)d。3治疗后观察组患者TNF-α和IL-1β水平分别为(11.35±3.01、10.28±2.11)pg/ml,明显显著低于对照组(19.83±4.02、17.42±2.95)pg/ml。4观察组治疗后总有效率为95.00%,显著高于对照组75.00%。5观察组患者治疗后转阴率为60.00%,显著高于对照组35.00%。6治疗后观察组菌种数为23株,显著少于对照组42株。结论:丹溪玉屏风颗粒联合纳他霉素治疗真菌性角膜炎的疗效优于单独运用纳他霉素,且无明显副作用。
