Methods Fifteen healthy, female SD rats were employed in the experiment. Sensitized systematically with keyhole limpet hemocyanin, the animals were inoculated with the same antigen through cochlea basal turn into the labyrinth. Adminstrated 5-bromo-2′-deoxyuridine intraperitoneally, the rats were sacrificed and the temporal bones were harvested at 3, 7,14 day after labyrinth vaccination respectively. The frozen sections of the decalcified samples were dealt with H-E staining and immunohistohemical methods to investigate the cellular infiltration, BrdUrd and IgG positive cells in the ES.

The long specific DNA probes were synthesized by polymerase chain reaction in the highly specific gene sequences of above 10 bacteria. The species-specific probes synthesized were inoculated on a nitrocellulose filter and hybridized with template DNA labeled with long-arm photosensitive biotin. The signal of hybridization reaction was observed to detect which bacteria infected. The sensitivity and specificity of the method were studied.

The compatibility of both Gvirens and B.firmus was researched. The fermentation filtrate of Gvirens , under the concentration of 70%, had not distinct inhibitory activity to B.firmus, the biomass of B.firmus would decrease with above the 70% filtrate of Gvirens, but the fermentation filtrate of B.firmus had not inhibitive role to Gvirens. 7, The cooperation control of both Gvirens and B.firm to the pine needle blight was explored:(1) Pathogen inoculation happened prior to the bio-control treatment for 7 days, however, the disease index and control effect had not distinct differences in any treatments even if combination of the two antagonists, but the susceptibility for different kind of pine were different.(2)when antagonist and pathogen were inoculated at the same time, some control effect to the pine needle blight, including certain extent cooperation control of both Gvirens and B.firm were proved, but it wasn't distinct when two antagonists used separately, and the change of the antagonist concentration had little effect to the control effect.
