About 30% of sudden deaths is ascribable to genetically determined morbid entities, mostly transmissible with the autosomal dominant pattern of inheritance, so that 50% of the first degree relatives are genetically affected (“carriers”) and exposed at risk;4) If toxic or illicit drug abuse was involved.展开更多

This paper focuses on matrine and reviews its action mechanism and toxicological action. It is concluded that the medicinal prospect of matrine is very broad, but more basic research and clinical trials are needed for more comprehensive evaluation.展开更多

To be spe- cific, Nε-（carboxymethyl）-Iysine （CML） is one of the most important components of AGEs, which is wildly distributed in the body and can be formed in vivo or in food processing and heating processes. Previous studies have shown that CML is a ma- jor immunological epitope in AGEs and plays an important role in diabetes and its complications, as well as in the development and progression of aging. This review summarized recent advances in major source, toxicological hazard and control mea- sures of CML.展开更多
