    Ying GAO;Hongwei HAO;Xinyu LIU;Min LIU;Weilin WANG;

    [Objective]To discuss the antioxidation of proanthocyanidins( OPCRR) in Rhodiola rosea L. [Methods]By establishing peroxide injury model of ICR mice induced by D-gal,intragastric administration of mice was carried out for continuous 49 d. Then,80,160 and 320( BW) mg/kg OPCRR were added into low-,middle- and high-dosage groups,respectively. The SOD,GSH,GSH-Px and MDA in serum,heart,liver and brain tissues and the MAO in liver and brain tissues were investigated. [Results] Compared with model control group,OPCRR at certain dosage could significantly enhance the SOD and GSH-Px activities of mice serum,heat,liver and brain tissues,and obviously reduced the MDA content. And high-dosage group was the most prominent. In high-dosage group,SOD activities of serum,heart,liver and brain tissues enhanced by 29. 5%,28. 1%,62. 7% and 90. 8%,respectively; GSH-Px activities enhanced by 67. 8%,58. 4%,32. 1% and50. 3%,respectively; MDA contents reduced by 19. 2%,30. 0%,33. 3% and 19. 2%. Besides,middle- and high-dosage groups showed extremely significant effects on reducing the brain MAO activity( P < 0. 01),which decreased by 22. 3% and 28. 6%,respectively. High-dosage group significantly reduced the liver MAO activity( P < 0. 05) by 36. 5%.

  • Inhibitory Effects of Schisandrin B on Expression of Cyclooxygenase-2 mRNA and Prostaglandin E_2 in Lung Tissues of Rats Exposed to Silica Dust

    Linhua FAN;Tianfu LIU;Min GUO;Maolin LIU;Pinghua FAN;

    [Objective] To discuss the inhibitory effects of schisandrin B( Sch-B) on the pulmonary fibrosis of rats to silica dust and its mechanism. [Methods]1 mL SiO 2suspension was injected into the trachea of rats so as to establish the rats model to silica dust. After exposed to SiO 2for 24 h,rats in Sch-B intervention group were given Sch-B 80 μg / g Sch-B by gavage. On the 3rd,7th,14 thand 28thdays after given Sch-B,lungs were collected and HE staining was carried out to observe the pathological change. Prostaglandin E2( PGE2) content in lung tissue was detected by ELISA; cyclooxygenase-2( COX-2) expression in lung tissue was researched by immunohistochemistry; and the COX-2mRNA expression in lung tissue was detected by RT-PCR. [Results]HE staining showed that rats in SiO 2exposed group had significant lung injury,showing significant pulmonary alveolitis in the early stage,and collagen deposition and pulmonary fibrosis in the late stage. The pulmonary alveolitis and pulmonary fibrosis in Sch-B intervention group were significantly weaker than those in SiO 2exposed group. PGE2 content of lung tissue in SiO 2exposed group was higher than that in normal control group( P < 0. 01). PGE2 contents in Sch-B intervention group on the3 rd,7th,14 thand 28thdays were all lower than those in SiO 2exposed group,which reduced by 41. 7%,38. 1%,36. 4% and 47. 6%,respectively( P < 0. 01 or P < 0. 05). After exposed to SiO 2,COX-2 expression enhanced significantly. After Sch-B intervention,COX-2 expression reduced. COX-2 mRNA expression in lung tissues of rats exposed to SiO 2was higher than that in normal control group on the 3rd,7th,14thand28 thdays,which enhanced by 1. 3,1. 6,1. 3 and 1. 7 times,respectively( P < 0. 01 or P < 0. 05). COX-2 expression in Sch-B intervention group was lower than that in SiO 2exposed group on the 3rd,7th,14 thand 28thdays,which reduced by 44. 4%,46. 8%,41. 7% and 41. 5%,respectively,and had statistical significance( P < 0. 01 or P < 0. 05). [Conclusions]The protective effects of Sch-B on lung injury of rats exposed to SiO 2might be related to the COX-2 expression inhibition of lung tissue and the induced synthesis and release of PGE2.

  • The Comparative Study and Exploration on Mechanism of Tripterygium wilfordii Tablets,Tripterygium wilfordii Polyglycoside and Water Decoction of Tripterygium wilfordii

    Qun FENG;Rong SUN;

    [Objective] To figure out the dosage range of Tripterygium wilfordii tablets,Tripterygium wilfordii polyglycoside and Water Decoction of Tripterygium wilfordii when used to treat inflammation. And their effects were compared and their mechanism of anti-inflammation was explored. It's expected that the study could provide reference basis for clinical medication. [Methods]Different dose of Tripterygium wilfordii tablets,Tripterygium wilfordii polyglycoside and Water Decoction of Tripterygium wilfordii were administrated to mice by intragastric administration. The ED50 of drugs used to treat acute inflammation was calculated by ear swelling model in mice induced by mixture of compound croton oil. After the last delivery,the content changes of PGE2,TNF-α and IL-2 in mice blood were detected. The effect of Tripterygium wilfordii tablets,Tripterygium wilfordii polyglycoside and Water Decoction of Tripterygium wilfordii on acue inflammation in mice was explored. [Results] The median effective dose ED50 of Tripterygium wilfordii tablets and Tripterygium wilfordii polyglycoside and Water Decoction of Tripterygium wilfordii when used to treat ear swelling in mice induced by mixture of compound croton oil were 17. 753 μg / kg,9. 235 7 mg / kg and0. 370 g / kg. When the median effective dose was presented by the dose of triptolide,then they reached 17. 753 μg / kg,8. 922 μg / kg and5. 667 μg / kg. It's 20. 30,10. 21 and 6. 48 times of the daily dosage of patient at the weight of 70 kg in clinic. The content of PGE2,TNF-αand IL-2 in mice blood of various medication groups were reduced significantly( P < 0. 05) and it displayed a good dose-effect relationship.[Conclusions]Tripterygium wilfordii tablets,Tripterygium wilfordii polyglycoside and Water Decoction of Tripterygium wilfordii could treat acute inflammation in mice induced by mixture of compound croton oil. And the strength in order were Water Decoction of Tripterygium wilfordii > Tripterygium wilfordii polyglycoside > Tripterygium wilfordii tablets. It indicated that triptolide had a good anti-inflammatory effect on acute inflammation and its effect showed a good dose-effect relationship. But it's not the only material base that had anti-inflammatory effect in Tripterygium wilfordii. Inhibiting the production and release of inflammatory factor PGE2,TNF-α and IL-2 was one of the mechanism of Tripterygium wilfordii tablets,Tripterygium wilfordii polyglycoside and Water Decoction of Tripterygium wilfordii which played a role in anti-inflammation.

    Shuling HE;Lingfa MA;Jingjun YANG;Yuhong FU;Yuwei CHANG;

    [Objective] To research the effects of soil physicochemical factors on the distribution of CORDYCEPS. [Methods] Literature survey,Interview and sampling analysis were carried out in the four streets and seven villages in Hezuo City of Gannan Tibetan Autonomous Prefecture( 102°47'51″- 103°22'00″ E,35°18'50″ N). Soil layers 0- 5,5- 10,10- 15 and 15- 20 cm in 21 sampling sites were analyzed.The plant number of CORDYCEPS was recorded,as well as thevegetation component,plant coverage,density and height,distribution status and growth status. [Results]In different soil layers,pH,TN,TP and AP had no significant differences; while WC,OM,TK and AK showed extremely significant differences. In soil layer 5- 10 cm,WC significantly affected the distribution of CORDYCEPS; while pH and TK had extremely significant impacts. The number of CORDYCEPS was the maximum in soil layer 5- 10 cm. In the first principal component,TP was the major factor affecting the population distribution of CORDYCEPS. In the second principal component,pH was the major factor. [Conclusions] CORDYCEPS had strict requirements for soil layer,TP and soil acidity-alkalinity. At the same time,WC,OM and TK also affected the distribution of CORDYCEPS.

    Junyi CHEN;Xiaolan YANG;Xing SUN;Boli LU;Ling CHEN;

    To promote the sustainable development of Traditional Chinese Medicine industry in Guizhou Province,and to effectively improve the agricultural planting benefit,the 2012 annual planting survey of Traditional Chinese Medicine was carried out; and analysis was conducted from the three aspects of the total area,yield and output value. The results showed that the total area,yield and output value of planted Traditional Chinese Medicines and wild plants conservation reached 267 918. 1 hm2,1 034 610 t and 9 092 740 thousand Yuan,respectively.Among the nine cities( prefectures) of Guizhou Province,Zunyi had the maximum values,which indicated that Zunyi had relatively great planting scale of Traditional Chinese Medicines,but the land productivity was low. Therefore,Guizhou Province should focus on improving the yield benefit per unit to increase the peasants' income,and take it as the top priority in the future in the development strategy of Traditional Chinese Medicines in Guizhou Province.
