ABSTRACT
AIM:
To study the effect of IFN-? inhalation on the anti-infection ability of the lungs in the immunocompromised host.METHODS:
The immunological factors in the immunocompromised rats and the immunocompromised rats administrated IFN-? via aerosol were investigated after 1, 3, 7 days when they were injected Candida albicans via tracheal The Canidda albicans count of the left lung was also determined after 7 days when injecting pathogen.RESULTS:
The Canidda albicans count of the left lung in IFN-? group was significantly less than that of control group. The phagocyting and bactericidal percentages, Ia antigen expression percentages, the levels of TNF-?, IL-1? and IL-6 in the culture supernatant of the AM, the activity of IFN-? and TNF-? in BALF (except the TNF-? on 7 th day) in IFN-? group were markedly higher than those in control group. The expression of IFN-? and IL-1? pulmonary tissues in IFN-? group was higher than that in control group. The expression of TNF-? in IFN-? group was less than that in control group. The expression of IL-6 was no changes between two groups. The levels of IFN-?, IL-1? and IL-6 in the blood (except IL-1? on 3 rd day), and the killing ability of the lymphocytes in blood had no difference between two groups.CONCLUSION:
Administration of IFN-? via aerosol obviously enhanced the anti-infection ability of the lungs in the immunocompromised host, but has no influence on the whole body cellular immunity.
