myasthenia gravias

Guang-Hua Niu, Xu Sun, Chun-Ming Zhang
OBJECTIVE: To investigate the effect and mechanisms of Compound Astragalus Recipe (CAR) for regulating cellular immune in patients with myasthenia gravis (MG). METHODS: Sixty MG patients were equally assigned to two groups randomly, the test group administered with CAR and the control group with prednisone for 3 months. Changes of patients' symptoms and adverse reactions were observed. The peripheral lymphocyte subsets distribution was examined by flow cytometry, and the levels of immunoglobulins and complements in the peripheral blood were measured by immuno-turbidimetry before and after treatment...

1. The inhibitory effect of N,N,N',N'-tetramethylethylene diamine (TEMED) on water soluble (WSAChE) and membrane bound (MBAChE) acetylcholinesterase was investigated. 2. TEMED (0.5-4.0 mM) reversibly inhibited WSAChE activity (18-62%) and MBAChE (20-61%) in a concentration dependent manner. 3. The IC50 being about 2.8 mM for WSAChE and 2.6 mM for MBAChE. 4. Lineweaver-Burk plots indicated that the nature of inhibition is noncompetitive for both water soluble and membrane bound acetylcholinesterase, with Km values 68 microM and 123 microM respectively...
