Study on anti-inflammatory, eliminating phlegm and bacteriostatic action of Yuxuan granule / 国际中医中药杂志

ABSTRACT

Objective To reveal the mechanism of Yuxuan granule(YXG) in treating pharyngitis from anti-inflammatory,expectorant,and antibacterial actions.Methods Xylene-induced ear edema and cotton pellet induced granuloma mice models were adopted to observe the anti-inflammatory effects of YXG Phenol red secretion in mice test was adopted to observe the expectorant activity of YXG Five bacteria by tube dilution method was adopted to observe antimicrobial action of YXG Besides,the changes of routine indexes in blood and tumor necrosis factor (TNF),interleukin-1 (IL-1) in serum were measured in acute pharyngitis models.Results YXG has shown a dose-dependent of its anti-inflammatory action.In the test of xylene induced mice ear swelling and cotton ball induced granuloma,the swelling degree of the control group,positive control groupand YXG high (6.14g/kg),medium (3.07g/kg) and low (1.53g/kg) concentration group were (9.00± 1.50) mg,(3.50±0.10)mg,(4.25±1.08)mg,(5.54±0.97)mg,(8.05±0.08)mg and (1.22±1.50)mg,(0.50±0.10)ag,(0.45± 0.08) mg,(0.75± 0.97) mg,(0.70 ± 0.08) mg respectively.YXG also had obviously expectorant effect to the golden staphylocoecus ameus,hemolytic streptococcus,streptococcus pneumoniae,salmonella typhi and corynebacterium diphtheriae,with the minimum inhibition concentration of 55,100,68 and 35 mg/ml respectively; YXG also reduced leukocyte count [percentage of leukocyte was (9.88± 1.22) × 109/L,(7.50± 1.58) ×109/L,(6.02± 1.05) × 109/L,(8.38± 1.13) × 109/L,(8.75 ± 1.08) × 109/L in the five groups respectively],neutrophils [the value was (35.62±5.00)×109/L,(28.49±3.40)×109/L,(28.89±5.22)× 109/L,(29.34±4.83)×109/L,(33.43 ± 4.27) × 109/L in the five groups respectively],lymphocytes [the value was (70.72± 5.04) ％,(67.89 ±4.37)％,(60.14±3.88)％,(65.38±4.45)％,(65.65±4.28)％ in the five groups respectively],TNF in blood serum [the value was (90.25±2.29)ng/ml,(80.23 ± 0.60) ng/ml,(76.83±0.33)ng/ml,(78.00 ± 0.34) ng/ml,(80.52±1.14)ng/ml in the five groups respectively] and IL-1 [the value was (222.06±50.22)pg/ml,(149.55±50.02)pg/ml,(130.37 ± 30.61)pg/ml,(158.68 ± 40.00)pg/ml,(178.76 ± 39.26)pg/ml in the five groups respectively] in the acute pharyngitis rat.Conclusion Through the anti-inflammatory,expectorant,antimicrobial activity and reducing levels of TNF,IL-1 YXG achieves the goal of treating pharyngitis.
