The child's hands have grown for almost a year and he has seen a doctor five or six times. He had eczema and used countless ointments, but none of them got better. After that, he bought these two medicines at the drugstore. Snake gall bitter cypress refreshing dew can obtain higher column efficiency, save analysis time and increase analysis flux, which is suitable for rapid analysis of plant samples and natural products, and also promotes the study of pharmacological activities of traditional Chinese medicine. With its unique advantages and characteristics, it is widely used in the study of drug metabolism. At present, the focus of drug metabolism research is mainly on the basis of liver microsomes and hepatocytes, and the in vitro metabolism of drugs is studied by isolating and culturing hepatocytes and recombinant single enzymes, so as to understand the metabolic pathway, metabolic stability and metabolites of metabolic enzymes biotransformation, and also to investigate the toxic and side effects of drugs on cells after metabolism. The immune pathogenesis of eczema and dermatitis is closely related to T lymphocytes. The balance of TH 1 and Th2 cell subsets maintains the normal immune function of the body, and the determination of TH 1/Th2 immune mode is mainly based on the levels of TH 1 and Th2 cytokines. Epidermal spongiform swelling is a characteristic pathological change of eczema and dermatitis, and its mechanism is that T cells induce apoptosis of keratinocytes. Activated CD4+T cells in eczema and dermatitis secrete IFN.7, which is one of the main cytokines causing skin pathology.
