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。

Because corticosteroid can modify the immunological process which is considered the major mechanism involved in AHS, it is used to treat AHS clinically. However, corticosteroid therapy may have deleterious effect (e.g., delayed healing of cutaneous lesions, infections, prolonged hospital stay). Therefore, the use of corticosteroids for AHS remains controversial. We reported a 54-year-old man who had underlying diabetes mellitus with chronic renal insufficiency, hypertension and hyperlipidemia. Allopurinol 100mg twice a day was initiated one month prior to admission. After taking the drug for 24 days, he developed a generalized mild itchy eruption on the trunk and upper extremities followed by chillness, fever, ocular discomfort and painful oral ulcer over one-week period and was admitted to the hospital. A skin biopsy revealed changes consistent with Stevens-Johnson syndrome.

本文报告一位54岁的男性患者，有高血压、高血脂、糖尿病及慢性肾脏功能不全的病史，最近发现有高尿酸血症(11.1mg/dL)而开始服用Allopurinol，在服用24日后，因为逐渐发生皮肤红疹搔痒、口腔溃疡、发烧、畏寒以及眼睛不适，一周之后到医院就医，经诊断为服用Allopurinol所造成之史帝文森－强生症候群(Stevens-Johnson syndrome)，因而在皮肤科住院接受治疗，由於病人有高血压、高血脂及糖尿病，所以入院后仅以支持疗法，并未给予全身性类固醇，然而病人之病况恶化，并有肾功能恶化，因而於住院两日后，转进肾脏科病房，在使用全身性类固醇治疗之后，病况持续改善，并在2周后出院。
