A Review The diseases caused by endotoxin have seriously affected human health. Previous studies have shown that p38 MAPK pathway is involved in the intracellular signal transduction induced by lipopolysaccharide (LPS), which plays an important role in the activation of inflammation-related cells to release inflammation mediator. Recently there have been some progresses in the isoforms distribution, substrate, molecular mechanism of regulating the release of inflammatory mediators, cellular specific activation and levels of p38 MAPK.

AIM: To investigate the effect of epigallocatechin-3-gallate (EGCG) on lipopolysaccharide (LPS)-induced p38 MAPK activation and tumor necrosis factor-? (TNF-?) secretion in macrophages. METHODS: Western blotting was used to detect the phosphorylation of p38 MAPK in mouse macrophages cultured in vitro. Enzyme linked immunosorbent assay was used to determine the secretion of TNF-? in macrophages. Electron microscopy was used to study the effect of EGCG on the structure of LPS. RESULTS: LPS caused activation of p38 MAPK and more production of TNF-?, EGCG inhibited LPS-induced phosphorylation of p38 MAPK and TNF-? production and had no effect on the structure of LPS. CONCLUSIONS: EGCG has no direct effect on LPS, but blocks cellular signal pathway. The inhibition of EGCG on LPS-induced TNF-? production is mediated, at least in part, through blocking of p38 MAPK pathway. [

The structure, karyotype and behavior of synaptonemal complex (SC) in the spermatocytes of hedgehog (Erinaceus euroaaus dealbatus (insectivora)) were analyzed by light and electron microscopy with a modified surface spread preparation which involves the use of sodium dodecyl-sulphate (SDS) and silver staining. The lateral elements of the synaptonemal complex have a constant width of about 50 nm, the distance between the two lateral elements is about 100 nm. The relative length and arm rationale constant for each autosomal SC. The relative length and arm ratio constant for ea of the autosomal SCs are very similar to that of mitotic autosome.The X and Y chromosome axes have a clear morphological distinction from the autosomal SC. The axes of X and Y chromosome pair and form a SC of certain length at pachytene stage. The axes of unpaired X and Y chromosome are heteropycnotic and display various morphological complexities. But these differentiations in hedgehog are primary than in other mammalians, such as human and mice. At pachytene stage the X and Y chromosome display an extensive side-by-side pairing segment with decreasing length as meiotic prophase progressed.

Objective To study the relationship between genotypes and phenotypes,geographical distribution,and the sites of infection of Trichophyton rubrum(T.rubrum).Methods The genotypes were determined by Southern blotting with a probe amplified from the small-subunit rDNA and adjacent internal transcribed spacer(ITS)regions.The phenotypes of T.rubrum were determined by conventional method.Results Twenty genotypes(DNA type A to T)and5phenotypes(villous,furrowed,granular,powdery,and woolly)were recognized among49strains of T.rubrum.Genotype A prevailed in all phenotypes except granu-lar type.Type B represented the most common genotype among the strains of villous type and furrowed type.Type A took the first place in powdery type and woolly type.All of the type A strains were from Dalian.Seven of9type B strains were from Nanjing.Six type C strains were all from Nanjing.The majority strains of21strains isolated from tinea unguium were type C,most of the16strains isolated from tinea cruris and tinea corporis were type A,8strains from tinea pedis were type B,and4strains from tinea capitis were type C.Conclusion There are certain possible relationships between genotypes and phenotypes,geographical distri-bution and sites of infection of T.rubrum.
