A promising genetic marker, sag5b, was cloned and expressed and the difference of the genes between highly virulent strain (RH) and less virulent strain(Prugniaud) of Toxoplasma gondii was compared.

Differentiated vascular smooth muscle cells (VSMC) are characterized as expression of specific marker genes, elongated and spindle-shaped morphology and the ability to contract in response to agonist stimulation.

The results indicated that the sd-t gene was linked to the marker genes Prp-b (Purple pericap b).

Effects of insulin on proliferation and differentiation of preadipocytes were analyzed by MTT and oil red O staining,and mRNA expression levels of fatty acid synthase(FAS) and acetyl-CoA carboxylase α(ACC1) genes,which were marker genes of differentiated adipocyte,were analyzed by semiquantitative RT-PCR.

This study was to establish the method of bovine preadipocyte cultruing,on the basis of this, using biology essential method,observed the shape change in preadipocyte differentiation,and using RT-PCR determind the expression of differentiation marker genes cultured with different medium.

HPV DNA tests were conducted among 7 068 women(aged 21～58)using Digene s HC-Ⅱ gene hybrid signal amplification technique.

Correlation between Fibrinogen and Variable Gene Marker of HCV;
