The situation of hearing in workers exposing to organic solvent at some productive facilities

The incidence of hearing loss in workers who have exposed to organic solvent is 16.3%. The workers in the General Painting Company have highest hearing loss incidence, followed by Phuc Yen and Yen Vien Shoe Companies and Hung Yen Plastic Company. The risk of hearing loss is increased with presence of hazardous factors that involved in working environment (organic solvents and noisy), simultaneously it depended on the pollution of these factors. The worker group that has exposed to one occupational hazardous factor as organic solvent showed sound deaf alone type in the audiogram, and the group that exposed to both factors showed the V shape audiogram

Study on immune response caused by a National Standard Rabies Vaccine candidate produced in Viet Nam

40 out of 50 subjects bitten by dog/cat were injected completely 4- 6 doses of rabies vaccine. Using ELISA, the authors found that 42.5% of serum samples that taken after injecting 4 doses of rabies vaccine had antibody titer 0.5IU/ml, met the WHO’s minimum requirement. The GMT was 2.71IU/ml. 62.5% of serum samples taken after injecting 6 doses of rabies vaccine had antibody titer 0.5IU/ml. The GMT was 3.14EU/ml

Study on immunological response of the vaccine candidate to selection MCQG for prevention of rabies manufactured in Vietnam

80% subjects among 50 bitten by dogs/cats were fully injected 4-6 doses of rabies vaccine. By ELISA (platelia Rage kit of Diagnostic Pasteur), we found that 42.5% of serum samples taken after injection 4 doses of rabies vaccine have titer 0.5IU/ml, it met WHO's minimum requirement. The GMT was 2.71 EU/ml. 62.5% of serum samples taken after injection 6 doses of rabies vaccine have titer 0.5IU/ml. The GMT was 3.14UE/ml.

Study on immune response caused by a National Standard Rabies Vaccine candidate produced in Viet Nam

40 out of 50 subjects bitten by dog/cat were injected completely 4- 6 doses of rabies vaccine. Using ELISA, the authors found that 42.5% of serum samples that taken after injecting 4 doses of rabies vaccine had antibody titer ³0.5IU/ml, met the WHO’s minimum requirement. The GMT was 2.71IU/ml. 62.5% of serum samples taken after injecting 6 doses of rabies vaccine had antibody titer ³0.5IU/ml. The GMT was 3.14EU/ml.
