[Meta-analysis of relationship of vitamin D receptor gene polymorphism and tuberculosis susceptibility].

Objective: To provide a quantitative summary in estimating the association between polymorphisms of 2 loci of FokI and TaqI in vitamin D receptor gene and susceptibility to tuberculosis by means of meta-analysis.

Methods: Databases CNKI, CBM, WanFang DATA, MEDLINE and PubMed were searched using "VDR", "polymorphisms" or "alleles", in combination with "tuberculosis", and a manual search of citations from relevant original studies and literature was also performed between January 1980 and November 2007.

[Study of mechanism on immune response in goats by different immunization with Helicobacter pylori and analyse of its prospects for using].

Objectives: To observe the effect of three different routes on the induction of immunogenicity to whole bacterial antigen of Vac A+ Helicobacter pylori strain (NCTC11637) and explore its mechanism.

Methods: Two milk goats and one pregnant goat were immunized by different routes respectively with whole bacterial of H. pylori (6 x 10(9) cfu/ml) cultivated by solid culture medium.
