Methods : in cultured lung explants without serum, the lipid component synthesis of pulmonary surfactant was evaluated in [ 3h ]-choline incorporation; mrna content of phosphocholine cytidylyltransferase ( cct ) in lung explants was investigated in rt-pcr; the changes of the ultrastructure of the at ii cells were observed with electron microscope; the expression of nmdar1 subtype was observed in immunohistochemistry staining; nitric oxide synthase ( nos ) activity, nitric oxide ( no ) content, superoxide dismutase ( sod ) level, malondialdehyde ( mda ) content and lactae dehydroase ( ldh ) level were determined by biochemistry methods . results : 1 . influence of glutamate on synthesis of the lipid component of pulmonary surfactant ? with l-arginine, glu inhibited [ 3h ]-choline incorporation with good dose-dependence and time-dependence; ( 2 ) mrna content of cct of the glu treatment groups was decreased; ( 3 ) glu increases the release of ldh in cultured lung explants; ( dwith electron microscope histochemistry, glu induced the changes of the ultrastruture of at ii iv cells 方法:采用成年大鼠肺組織無(wú)血清培養(yǎng),運(yùn)用[~3h]-膽堿摻入法測(cè)定ps主要脂質(zhì)磷脂酰膽堿(pc)合成量;rt-pcr擴(kuò)增檢測(cè)肺組織中pc合成限速酶磷酸膽堿二胞苷?;D(zhuǎn)移酶(cct)mrna含量;透射電子顯微鏡法觀察肺泡型上皮細(xì)胞和ps系統(tǒng)超微結(jié)構(gòu)的變化;免疫組織化學(xué)染色檢測(cè)glu的受體nmdar1亞單位的表達(dá);生化測(cè)定肺組織乳酸脫氫酶(ldh)釋放量和肺組織勻漿中一氧化氮合酶(nos)活性、一氧化氮(no)生成量、超氧化物歧化酶(sod)水平以及丙二醛(mda)含量。
In addition, the principle of component synthesis vibration suppressing ( csvs ) method is also briefly introduced and summarized to several lemmas, which can suppress flexible vibration by utilizing the character of vibration system itself and has the characters of simple, multiform, easy to apply and so on 另外,為了將分力合成方法應(yīng)用于撓性系統(tǒng)的振動(dòng)抑制,簡(jiǎn)要地介紹了分力合成方法的一些基本概念及原理。針對(duì)采用推力器作為執(zhí)行機(jī)構(gòu)的撓性航天器姿態(tài)機(jī)動(dòng)的振動(dòng)抑制問(wèn)題,提出了將分力合成振動(dòng)抑制(csvs)方法和基于分布?jí)弘娫?pzt)的主動(dòng)振動(dòng)抑制技術(shù)相結(jié)合的一種復(fù)合主動(dòng)控制方法。
