Abstract:
Objective:To evaluate 1,8-cineol as vaccine adjuvants to enhance influenza vaccine immune efficacy.Methods:80 BALB/c mice were divided into blank control group,1,8-cineol group,HA group and HA+ 1,8-cineol group,each group of 20.Blank control group normal breeding,HA group accepted HA protein 0.2 μg,the HA+1,8-cineol group was given 0.2 μg HA+ 100 mg/kg 1,8-cineol,1,8-cineol group was given 100 mg/kg 1,8-cineol.Except the blank group,other groups of mice intranasal immunized for three times interval of one week.At the fourth weeks each mice was infected with 10LD50 influenza virus FM1.On the 6 days after the infected,10 mice in each group were collected serum,using enzyme-linked immunoassay(ELISA)to detect serum IgG,IgG1b,IgG2a, IgG2b in 450 nm absorbance values(OD).Removed the lung tissue and measured the lung index and pathological.Remaining mice continue to observe 15 days and record the deaths,calculating the infected mice survival rate.Results:Compared with the HA group, HA + 1,8-cineol group can reduce the lung index,alleviate the pulmonary lesions,improve the serum IgG,IgG1b,IgG2a,and increases the survival rate of infected mice.Conclusion:1,8-cineol as vaccine adjuvants,can strengthen the immune effect of influenza vaccine.
