Osmotic and ionic induced salt stress suppresses plant growth. In a previous study, B30, isolated from , improved seed germination, root length, and seedling length of bermudagrass () under salt stress. In this study, B30 application improved fresh weight and dry weight, carotenoid and chlorophyll levels, catalase and superoxide dismutase activities, indole acetic acid content and K concentration.

In this study, the mechanisms by which La influences bahiagrass () growth were evaluated by the analyses of root growth, root activity, cell wall polysaccharide content, respiration intensity, ascorbic acid oxidase (AAO) and polyphenol oxidase (PPO) activity, the subcellular distribution of mitochondria, transcription in roots, photosynthetic properties, chlorophyll fluorescence parameters, and chlorophyll content. The application of 0.

Objective: To observe the effect of Yishen Jianpi Yangxue Tongli Therapy (YJYTT) in treating polycystic ovary syndrome (PCOS) and to explore the therapeutic mechanism of YJYTT.
Methods: One hundred and seven PCOS patients with syndrome differentiation of TCM as Pi-Shen Yang deficiency were randomly divided into two groups, the treated group (n = 76) was treated with Chinese herbal medicine, while the control group (n = 31) was treated by clomiphen. The therapeutic effect in both groups and the change of body mass index (BMI), Ferriman-Gallway (F-G) score, serum sex hormones and serum oral glucose tolerance test (OGTT) before and after treatment were observed.
