Background: QingLiCao has been used for the treatment of skin diseases such as eczematous dermatitis in China-Vietnam border area. However, the mechanism of treatment effect is still unclear. This study aimed to investigate the inhibitory effect of pathogenic bacteria and fungus of eczematous dermatitis and evaluate the antioxidant activity of phenolic contents from QingLiCao, will be helpful to further understand the mechanism of action. Materials and Methods: The in vitro phenolic antimicrobial activity was determined using disc diffusion and antioxidant activity was evaluated by spectrophotometry. Results: The experimental results showed that the phenolics from QingLiCao had excellent antimicrobial activity to pathogenic bacteria and fungus of eczematous dermatitis, similar results were observed for the antioxidant activity. Conclusion: The results support the proposition that phenolic from QingLiCao might be a promising anti-eczematous dermatitis natural active ingredients merit further investigations. |

A recognition method of red jujube disease disease based on portable microscope and particle swarm neural network is put forward in order to achieve early detection of disease. First, grayscale processing, median filtering and threshold segmentation are used to deal with microscopic image, then, eight eigenvectors are extracted based on R, G, B color space, finally, red jujube leaf disease recognition model is established based on BP neural network which is optimized using particle swarm algorithm.The experimental results show that this method can realize early identification of jujube leaf disease comparing with the ordinary digital camera and the identification accuracy reached 90%. |
