OBJECTIVETo explore the effect of Yinqiao detoxifcation oral liquid on activity of natural killer cells (NK) and serum content of TNF-alpha, TGF-beta1 of BALB/C nude mouse infected by influenza virus.
METHODTo establish infected mice model by FM1 followed by intragastric administration of Yinqiao detoxifcation oral liquid for treatment. LDH method was used to observe NK cells. ELISA method was used to determine the levels of TNF-alpha, TGF-beta1, in serum on 1st, 3rd, 5th, 7th days after infection.
RESULTComparing to the normal group, the NK activity of the model group was significantly increased on 1 dpi (day post infection), and significantly decreased on 3, 5, 7 dpi. The NK activity of three dosage groups (5, 10, 20 g x kg(-1)) of Yinqiao detoxifcation oral liquid were respectively higher than that of the model on 3, 5, 7 dpi, especially with high dose (P < 0.01). The serum level of TNF-alpha and TGF-beta1 of model group is higher than that of normal group on 1, 3, 5, 7 d. Compared with model group, the serum level of Yinqiao detoxifcation oral liquid groups (5, 10, 20 g x kg(-1)) were decreased in different degree on every time point, especially the serum level of the higher dose of Yinqiao detoxifcation oral liquid decreased on 3 dpi (P < 0.05), Yinqiao detoxifcation oral liquid inhibit the serum level of TGF-beta1 in a dose-dependent manner.
CONCLUSIONYinqiao detoxifcation oral liquid could enhance the activity of NK cell and decrease the serum level of TNF-alpha and TGF-beta1 of the mice infected by influenza virus.
