RESUMEN
OBJECTIVE: To investigate the effect of Xianxiong decoction on the mice with acute lung injury induced by lipopolysaccharide. METHOD: Eighty female ICR mice were randomly divided into 8 groups: model group, Xianxiong decoction group, Daxianxiong decoction group, Xianxiong decoction group without Kansui Radix group, Xianxiong decoction group without Glycyrrhizae Radix et Rhizoma group, Glycyrrhizae Radix et Rhizoma and Kansui Radix group, normal group and control group. Animals of each group, except normal group, were undertaken intraperitoneal injection and intranasal inhalation of lipopolysaccharide (LPS) on day 1, 2, 3 to establish acute lung injury (ALI) model. 30 min after modeling, 0.2 mL corresponding drugs were administrated to each mice, dexam ethasone and normal saline were given to the mice of control group and normal group respectively. White blood cell in blood, neutrophil percentage of blood and bronchoalveolar lavage fluid (BALF) supernatant, the ratio of wet and dry lung tissue ( W/D), histopathological changes of lung tissue were estimated. Sixty ICR mice were randomly divided into normal, model, control, high, middle and low dose Xianxiong decoction groups and were modeled in the same way. ELISA was applied to detect the level of NF-kappaB, TNF-alpha and IL-6 in BALF, PCR for NF-kappaB and TNF-alpha mRNA in lung tissue, and Western blot for NF-kappaB and TNF-alpha. Half of 20 ICR mice were administrated with Xianxiong decoction of its maximum tolerant normal saline. RESULT: Compared with model group, the number of WBC in blood of Xianxiong decoction group mice decreased (P < 0.01), percentage of neutrophils in both blood and BALF decreased as well (P < 0.01, P < 0.05); it also significantly reduced the ratio of W/D (P < 0.01); and found the alveolar wall, the number of inflammatory cells infiltrating improved, compared with model group. Xianxiong decoction reduced the level of NF-kappaB, TNF-alpha and IL-6 in BALF (P < 0.01, P < 0.01, P < 0.05); its high and low dose groups only found TNF-alpha level declined. Five mice died 24 h after administration of Xianxiong decoction which indicated its toxicity when other influential factors were considered. CONCLUSION: Xianxiong decoction is effective on the ALI mice induced by LPS, but it is of toxicity at 3 g x mL(-1).

The verse "eighteen antagonism" of Chinese materia medica is a kind of describing of drug nature concerning the incompatibility of drugs in compound prescription. Through organizing the medical books in different historical periods, it is found that the drugs in this verse basically coming from TAO Hong-jing's ben cao jing ji zhu (Variorum of Shennong's Classic of Materia Medica), while the style of verse mostly appeared during the Song-Jin-Yuan period was made. The formed verse was explained and supplemented further in the Ming Dynasty, the basis of which appeared in the Song-Jin-Yuan Dynasty, resulting in the increase of the number of antagonistic drugs and lengthy verse. The origin of the verse seen in Ru men shi qin (Confucians' Duties to Their Parents) and those in other books was not identical and was the most popular one after the Qing Dynasty, becoming the most popularly known even today.
