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

[Methods] In this experiment,the structure of polysaccharides was analyzed by Fourier transform infrared spectroscopy. The experiment was divided into the polysaccharide groups of high,medium and low dose of ZhuQin,the extraction group of ZhuQin,the polysaccharide group of Atractylodes,the positive drug group,the blank group and the model group. The model of immunosuppressed mice was established by intraperitoneal injection of cyclophosphamide. The carbon clearance index,immune organ index,serum hemolysin,spleen T and B lymphocyte transformation rate were determined. [Results]The results show that the polysaccharides have obvious absorption peaks of polysaccharides; Formula extracts and polysaccharides can enhance the immune function of immunosuppressive mice at a certain dose level,and the effect of formula polysaccharide is better than that of extract and single traditional Chinese medicine polysaccharides. [Conclusions] The results suggest that the polysaccharides of ZhuQin Formula and Atractylodes may be acidic polysaccharides containing pyran ring and furan ring. ZhuQin Formula polysaccharide may play an immunomodulatory role mainly by improving the specific immunity of the organism.展开更多

文摘The study examined the inhibitory effect of Atractylodes macrocephala (AM) on the uterine contraction during premature delivery and explored its electrophysiological mechanism by studying the effects of AM on the Ca^2+-activated K^+ currents of pregnant human myometrial smooth muscle cells with or without the treatment with intedeukin-6. 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.

文摘[Objectives] To investigate the infrared identification of ZhuQin Formula and Atractylodes polysaccharides and its effect on immune function in immunocompromised mice. [Methods] In this experiment,the structure of polysaccharides was analyzed by Fourier transform infrared spectroscopy. The experiment was divided into the polysaccharide groups of high,medium and low dose of ZhuQin,the extraction group of ZhuQin,the polysaccharide group of Atractylodes,the positive drug group,the blank group and the model group. The model of immunosuppressed mice was established by intraperitoneal injection of cyclophosphamide. The carbon clearance index,immune organ index,serum hemolysin,spleen T and B lymphocyte transformation rate were determined. [Results]The results show that the polysaccharides have obvious absorption peaks of polysaccharides; Formula extracts and polysaccharides can enhance the immune function of immunosuppressive mice at a certain dose level,and the effect of formula polysaccharide is better than that of extract and single traditional Chinese medicine polysaccharides. [Conclusions] The results suggest that the polysaccharides of ZhuQin Formula and Atractylodes may be acidic polysaccharides containing pyran ring and furan ring. ZhuQin Formula polysaccharide may play an immunomodulatory role mainly by improving the specific immunity of the organism.

文摘Atractylodes Chinensis(DC)Koidz is a perennial herb often used as a prescription medicine for influenza,to invigorate the spleen and remove dampness.The quality of the herb is determined by the quality of the seedlings.The traditional A.chinensis seedling production technique has nonuniform seedlings and low mechanisation.The plug seedling technique was used to produce A.Chinensis seedlings.This study was conducted to determine the growth characteristics of A.Chinensis seedlings according to the cell size of plug trays and number of days after sowing.Plant height,stem diameter,rhizome diameter,number of leaves,leaf area,and shoot dry and fresh weight of A.Chinensis seedlings were significantly higher in the P32-D treatment than in the P72,P50,and P32 treatments,but not significantly different from the P28-D treatment 60 d after sowing.The P28-D treatment resulted in a considerable drop in rhizome fresh weight and healthy seedling index,both of which are key indicators for assessing seedling quality.Although the differences in Pn among treatments were not significantly different,Tr was considerably greater in A.Chinensis seedlings treated with P32-D and P28-D than in the other three treatments.The P32-D and P28-D treatments had considerably greater potential maximum photochemical efficiency of PSII,quantum yield of photosystem II,photochemical quenching and electron transport rate than the other three treatments.Root vitality of A.Chinensis seedlings was significantly stronger in the P32-D treatment than in the other four treatments,and it was 1.9 times higher than in the P28-D treatment.The soluble protein,soluble sugar,and starch contents of A.Chinensis seedlings were highest in the P32-D treatment,but the differences among treatments were not significant.LUE,EUE,PY and EY were significantly higher in the P32-D treatment than in the other four treatments,being 1.3,1.3,1.4 and 1.4 times higher than in P28-D,respectively.On the other hand,as for the change in the growth of A.Chinensis seedlings according to the number of days after sowing,the growth of shoots and rhizome was most vigorous at the 60 d after sowing,while the fresh weight of the rhizome,which can be considered as an indicator of root growth,increased steadily during the experiment but slowed down after 60 d.As a result,32-cell deepened plug trays and a seedling nursery for a period of 60-75 d are recommended for commercial cultivation of A.Chinensis seedlings.This will provide technical support for production in A.Chinensis seedling.
