ABSTRACT
Objective To compare the effect of integration processing technology of origin with traditional cutting processing technology of Mosla chinensis on pyretic rats caused by LPS and inflammatory RAW264.7 cells induced by LPS, and provide the feasible basis for the implementation of integration processing technology of origin and traditional efficacy of the relieving exterior effects of M. chinensis. Methods The rats were intervened by M. chinensis (volatile oil, decoction), and the model of heat syndrome was established by ip of LPS. The temperature changes of the fever rats were observed. The levels of serum prostaglandin E2 (PGE2), tumor necrosis factor-α (TNF-α), adenosine cyclic phosphate (cAMP), interleukin-1β (IL-1β), and myeloperoxidase (MPO) in liver tissue were detected. The effects of integration processing of origin and traditional cutting processing of M. chinensis on heat syndrome rats were compared. The cell viability of LPS stimulated RAW264.7 macrophages cells after administration of different concentration of M. chinensis (decoction and volatile oil) was detected, and the NO secretion was determinated by ELISA for comparing the anti-inflammatory effect of two processing methods. Results The treatment of processed M. chinensis can decrease the anus temperature and the content of PGE2, TNF-α, CAMP, IL-1β, MPO, and enhance cellular immunity. Moreover the efficacy of integration processing of origin is better than traditional cutting processing, and the efficacy of M. chinensis decoction is better than volatile oil. Conclusion The integration processing technology of origin for M. chinensis is feasible.
ABSTRACT
To compare the effect of integration processing technology of origin (IPTO) and traditional cutting processing technology (TCPT) of Moslae Herba for lung-Yang deficiency rats caused by complex factors, analyze the mechanism, and provide the modern pharmacology basis for the implementation of IPTO of Moslae Herba. The rat models of lung-Yang deficiency were established by smoking + swimming in ice water + drinking ice water. The model rats were randomly divided into different groups, and were treated with intragastric administration for 30 d. Then the general signs, anal temperature and autonomic activity of the rats were observed. The pathological morphology of lung tissues was observed, and the positive expression of tumor necrosis factor (TNF-α) was observed by immunohistochemical method, and the hematological indexes were determined. Enzyme linked immunosorbent assay (ELISA) method was used to detect serum nitric oxide (NO), immunoglobulin G (IGG), malondialdehyde (MDA), thromboxane B2 (TXB2) and interleukin-8 (IL-8) level, and the organ coefficients of heart, liver, spleen, lung, kidney and other organs were calculated. According to the results, Moslae Herba volatile oil and decoction could improve the general signs and autonomic activities of lung-Yang deficiency rats, improve the body weight, rectal temperature, and the content of IGG in serum of lung-Yang deficiency rats, reduce organ coefficients of heart, liver, spleen, lung and kidney, serum NO, MDA, TXB2, IL-8 contents, white blood cell and TNF-α mean optical density in the lung tissues of rats. witg statistically significant difference (<0.01 or <0.05). The effects of IPTO volatile oil and water decoction were slightly higher. Therefore, Moslae Herba has therapeutic effect on lung-Yang deficiency rats, and ICPT has better effect, whose mechanism may be related to the intervention of TNF-α expression, improving the level of IGG, and inhibiting NO, MDA, IL-8, and TXB2 levels.
