摘要
痤疮是毛囊皮脂腺单位的一种慢性炎症性皮肤病。表皮葡萄球菌是一种条件致病菌,是痤疮发生的重要因素之一。该实验从面部痤疮中分离出表皮葡萄球菌,观察绿茶汁对其是否具有抑制作用。抑菌圈实验比较绿茶汁对面部痤疮细菌(FA)、大肠杆菌、枯草杆菌以及金色葡萄球菌的抑菌效果,实验结果显示,绿茶汁对FA和金色葡萄球菌的抑制效果最为明显,抑菌圈最清楚。菌种鉴定结果,FA的主要菌为金色葡萄球菌。通过将不同浓度的绿茶汁与FA混合培养24 h,做平板计数实验,实验结果显示,绿茶汁对FA的抑制效果随着绿茶汁浓度的增加而增强。实验创新思路来源于生活,实验结果运用于生活,为广大因面部痤疮而烦恼的人们提供了一条新途径。
Acne is a chronic inflammatory skin disease of the pilosebaceous unit. While the major acne bacteria are Staphylococcus epidermidis. It is an opportunistic pathogen and one of the important factors for the occurrence of acne. In this experiment,we isolated staphylococcus epidermidis from facial acne. Then,we observed whether the green tea extractive have the inhibitory effect of staphylococcus epidermidis. Experiment and compared the green tea extractive effectiveness of against main strains of the extractive of facial acne with Escherichia coli,Bacillus subtilis,Golden staph by using inhibition zone,experimental results show that the inhibitory effect of green tea extractive on staphylococcus gold is most evident. By diluting different concentration gradients of green tea extractives blended with acne extractive make tablet counting experiments,experimental results showed inhibitory effects of extractives of green tea extractive for acne with increasing concentration and enhanced,to some a few bacteria survive after suppression of time. Final strain identification and expectations met that major acne bacteria is staphylococcus gold. Experiment of innovative ideas comes from life,the experimental results used in life,for the majority of people worry about facial acne offers a new way.
