The seedlings of Dendrobium officinale interplanted with Pleurotus os- treatus grew by 2.78 cm during 10 weeks on cultivation beds, and the seedlings grew by 2.68 cm in the cultivation beds without interplanting arrangement. These demonstrated that the interplanting of Dendrobium officinale and Pleurotus ostreatus has none adverse effects on growth of Dendrobium officinale.展开更多

To investigate the role of endogenous heme oxygenase (HO)/carbon monoxide (CO) system in regulating the process of intussusception (IN) induced by administration of lipopolysaccharide (LPS) in rats. Methods. IN model of rats were induced by lipopolysaccharide. HO activity was determined by the amount of bilirubin formation which was measured with a doublebeam spectrophotometer, and HbCO formation was measured by COoximeter. Results. The results showed that LPS (10mg/kg) caused IN in up to 40% of the rats at 6h after treatment of LPS. The incidence of IN were significantly increased by 50% (P<005) and by 832%(P<001) in HO substrate(hemeLlysinate)treated rats and in exogenous COtreated rats, respectively; but it was significantly decreased by 418%(P<005) after administration of ZnDPBG, an inhibitor of heme oxygenase (HO) activity. Furthermore, LPS increased HO activity, HbCO formation cGMP content within colic smooth muscle and the plasma level of cGMP, and these parameters were significantly elevated by 626%(P<001), 400%(P<001), 493%(P<005) and 38%(P<005), respectively, compared with LPSnonIN rats. Conclusion. It is suggested that endogenous HO/CO system plays an important role in the process of IN induced by LPS, and inhibition of HO activity may decrease the formation of IN.展开更多
