Abstract:
OBJECTIVE:To investigate the inhibitory effect of Baixuan xiatare tablet on the model mouse with allergic contact dermatitis (ACD). METHODS:60 BALB/c mice were equally randomized into normal control (isometric solvent) group,model (isometric solvent)group,ebastine(positive control,0.003 g/kg)group and the groups of high,middle and low doses of Baixuan xiatare tablet(2.0,1.0 and 0.5 g/kg). The mice were given drugs,ig,once daily for 14 consecutive days. 0.5% 2,4-dinitrofluoro-benzene(DNFB)acetone olive oil solution was applied,for sensitization,on the prepared mouse’s skins one and two days before administration,and 0.2% DNFB acetone olive oil solution on their left ears 16 days thereafter to establish mouse models of ACD. At 48 h after successful establishment of the models,the thickness of the mouse’s left ear margin was measured and the difference value and swelling degree were calculated;flow cytometer was used to determine the levels of T lymphocyte subsets CD4+ and CD8+ in mouse blood and calculate the ratio of CD4+ to CD8+;the levels of interleukin 4(IL-4)and IL-6 in mouse serum were de-termined. RESULTS:Compared with normal control group,those in the model group had higher difference value of ear margin and swelling degree,lower level of CD4+ in blood and ratio of CD4+ to CD8+,and higher content of IL-6 in serum. There was statisti-cally difference (P<0.01). Compared with model group,those in the groups of high,middle and low doses of Baixuan xiatare tablet had lower degree of left ear swelling and higher level of CD4+ in blood;those in the groups of high and middle doses thereof had lower difference value of left ear margin and level of IL-6 in serum;and those in the group of high dose thereof had higher lev-el of CD8+ in blood. There was statistically significance(P<0.01 or P<0.05). CONCLUSIONS:Baixuan xiatare tablet has inhibi-tory effect to some degree on the mouse model with ACD by a mechanism which may be related to the balance of subsets CD4+and CD8+in blood and the reduction of IL-6 in serum.
