Then, it analyzed the causes of continuous cropping obstacles for Atractylodes macrocephala Koidz. In the end, in order to provide guidance for pro- moting sustainable development of Atractylodes macrocephala Koidz industry in Pingjiang County, it put forward some control methods for eliminating continuous cropping obstacles of Atractylodes macrocephala Koidz, including breeding varieties with high resistance; applying rotation cropping and intercropping reasonable; rational fertilization and soil disinfection; introducing antagonistic bacterial and eliminating au- tointoxication.展开更多

Single cells were acutely isolated from pregnant human myometrial smooth muscles. Whole-cell Ca^2＋-activated K^＋ currents were recorded by using an Axopatchl-D amplifier. The cells were divided into three groups： group A in which AM was added into perfusate, group B, in which interleukin-6 was added into perfusate） and group C in which AM was added into perfusate after addition of interleukin-6. IL-6 10 ng/mL inhibited BKca by 36.9%±13.7% as compared with control （P〈0.01）. AM at 2 mg/mL raised BKca by 36.7%±22.6% or 45.2%±13.7% with or without the treatment of IL-6, respectively （P〈0.01）. It is concluded that AM was able to enhance the BKca of pregnant human myometrial smooth muscle cells treated or untreated with interleukin-6 and its effect on the BKca IL-treated cells was stronger that its effect on BKca of untreated cells. Our results suggested that AM can help to maintain the membrane potentials and the resting status of pregnant human myometrial smooth muscle cells.展开更多

[Method] The control effects of 60% validamycin A SP against seeding blight of A. macrocephala were studied in the field, and compared with that of control agent 20% bismerthiazol WP. [Result] At 14 d post the third spraying, the control effect of 60% validamycin A SP at the dose of 495-540 g/hm;was 76.9%,which was equivalent to that of control agent 20% bismerthiazol WP sprayed at the dose of 270 g/hm;（76.7%）. [Conclusion] 60% Validamycin A SP could be used as the ideal agent against seedling blight of A. macrocephala, with good prospects of application and popularization.展开更多
