The first part consists of three experiments:(1) The rings were incubated in KH, 20, 50 mmol/L 〓 for 1 house, relaxation in response to the EDHF stimuli A23187 in 30nmol/L U46619-induced preconrtaction in the presence of 7 μ mol/L indomethacin, a cyclooxygenase inhibitor, 300μmol/L LNNA, a nitric oxide biosyhnthesis inhibitor, and 1mmol/L tetraethylammonium , a 〓 blocker, or 3 μmol/L glibenclamide , a 〓 blocker, was compared with the control;(2) After the arteries were incubated in KH, UW solution or HTK solution at 4℃ for 4 hours, endothelium-derived relaxation (percentage of 30nmol/L U46619 precontraction) was induced by A23187 in the present of 7 μmol/L indomethacir and 300μmol/L LNNA;(3) After incubation with KH, UW solution and STH (either at 37℃ in oxygenated organ chamber or at 4℃ in a refrigerator for 4 hours), endothelium-derived relaxation (percentage of 30nmol/L U46619 precontraction) was induced by A23187 in the present of 7 μ mol/L indomethacin and 300 μmol/L LNNA.

第一部分研究结果：（1）单纯浸泡于KH的冠状动脉A23187能引发66.67％的血管舒张反应，经TEA及20mmol／L、50mmol／L钾离子作用后，血管舒张反应程度显著降低，但经GBM作用后改变不明显；（2）与保存于KH的冠状动脉相比，A23187引发的血管舒张反应程度，保存于UW液的明显下降，保存于HTK液的无明显变化；（3）在37℃条件下，血管环浸泡于STH出现缓慢轻微的舒张反应，浸泡于UW液初期出现短暂收缩反应，但此后主要以舒张为主：在37℃条件下，血管经UW液保存后，U46619引发的收缩反应程度降低；不论在37℃或4℃条件下，A23187引发的血管舒张反应，经UW液保存后明显下降，但用STH保存后变化不明显。

Methods: Fresh saphena rings were sudied in organ chamber after incubating with Krebs-Henseleit bicarbonate solutions, FWM, KH with 0.1mmol/L NCR, FWM with 0.1mmol/L NCR at 37℃ for 1 hour. Precontraction induced by prostaglandin F2 (U4661930nmol/L) and endothelium-dependent relaxation induced by calcium ionophore A23187 l0^(-10~l0^(-6) mol/L were measured in the presence of indomethacin (7μmol/L) and LNNA (300μmol/L). Result: No significant changes were found in the 4 groups under the light microscope.

采用器官槽法研究在37℃有氧条件下用重碳酸盐缓冲液、含0.1mmol/L NCR的KH液、FWM液、含0.1mmol/L NCR的FWM液中浸泡血管环1h后，再用7μmol/L吲哚美辛和300 μmol/L N-硝基－L-精氨酸作用后，检测30 nmol/L U46619及不同浓度A23187引发的血管收缩舒张反应。

The presence of REE tetrad effects in apatites and whole rocks of S-type granites has been reported by Sha and Chappell (1999) and Zhao et al.(1999), respectively. The REE tetrad effect in minerals, such as apatite, spessartite, beryl, alkali feldspar and spodumene, from all zones of Altay No. 3 pegmatite has been found remarkable, and the fractionations among isovalent incompatible elements in these minerals are also significant. This paper puts forward that the REE tetrad effect is one of the basic features of peraluminous melts and the origin of REE tetrad effect might be probably related to some processes prior to the formation of pegmatite magma. The immiscibile liquid separation between silicate melt and hydrosaline melt may be responsible for it.

由于阿尔泰3号伟晶岩脉各带磷灰石以及与其共生的石榴石、绿柱石、碱性长石、锂辉石矿物均存在明显的稀土"四重效应"以及相同电价、相似离子半径的不相容元素间存在显著的分异，并结合最近赵振华等(1999)和Sha and Chappell(1999)报道S型花岗岩全岩和单矿物(磷灰石、独居石、长石、黄玉等)均存在稀土"四重效应"这一现象，本文研究提出，稀土"四重效应"是富挥发分过铝质岩浆体系的一个基本特征，其机制既不可能由含稀土的副矿物早期结晶引起残余熔体相中REE含量变化的结果，也不能定性地归因于流体相与熔体相相互作用过程中稀土元素在流体/熔体之间分异的结果，而很可能与伟晶岩岩浆形成之前某些过程密切相关，S型花岗岩岩浆在液相线以上存在硅酸盐熔体与高盐熔体的不混溶液相分离有可能是过铝质岩浆体系产生稀土"四重效应"的主要原因。
