高血压是与吸烟相关的心血管病危险因素,但高血压和吸烟的剂量效应关系尚不清楚。本研究针对西班牙裔人群,他们吸烟暴露通常相对较低。方法:研究采用美国西班牙裔18~76岁成年人6年随访研究的数据,明确吸烟与高血压的剂量效应。高血压定义为血压≥140/90mm Hg(1 mm Hg=0.133kPa)或服用降压药。校正潜在的混杂因素及中介因素,包括尿白蛋白与肌酐比值(在吸烟者中随时间推移而恶化)。

A class of asynchronous matrix multi-splitting multi-parameter relaxation methods, including the asynchronous matrix multisplitting SAOR, SSOR and SGS methods as well. as the known asynchronous matrix multisplitting AOR, SOR and GS methods, etc., is proposed for solving the large sparse systems of linear equations by making use of the principle of sufficiently using the delayed information. These new methods can greatly execute the parallel computational efficiency of the MIMD-systems, and are shown to be convergent when the coefficient matrices are H-matrices. Moreover, necessary and sufficient conditions ensuring the convergence of these methods are concluded for the case that the coefficient matrices are L-matrices.

IN fractal geometry, two classes of sets play important roles. One is the regular set (the setHausdorff and packing dimension coincide), the other is the set whose Bouligand dimensionexists. A natural question is how to measure 'the size' of these sets mentioned above. In thisnote, by using category, we answer this question. The main result is Theorem 1.

Objective:To investigate effects of ethanol extract of Abrus precatorius leaves（EAPL） on egg albumin induced mast cell degranulation in mice and passive cutaneous anaphylaxis in rats. Methods:In present study ethanol extract of Abrus precatorius leaves（EAPL） at doses of 100,125, 150 mg/kg i.p were evaluated for preliminary phytochemical screening,acute toxicity studies and egg albumin induced mast cell degranulation in mice and passive cutaneous anaphylaxis in rats. Results:The results of present investigation showed that the LD50 of EAPL is more than 1300 mg/ ***（100-150 mg/kg,i.p.） significantly protect egg albumin induced degranulation of mast cell and inhibit area of leakage of dye in passive cutaneous *** studies observed presence of saponin,alkaloids,flavonoids,and ***:In conclusion EAPL possesses anti asthmatic potential.

THE oceanic lithosphere is composed of oceanic crust and upper mantle. It is widely accepted that the Troodos ophiolitic section represents the oceanic crust section, which consists of ultramafic cumulates in the bottom, and grades upward into cumulative gabbros, isotropic gabbro, sheeted dikes and pillow lavas, covered by abyssal sediments. According to the marine geophysical investigation, the oceanic crust can be divided into three layers which from top to bot-

THE Early Ordovician Baiyungang Formation limestone in Tarim is characterized by multiplemagnetic components including primary remanent magnetism (PRM) and late remagnetiza-tion. Considerable attention should be paid to its petromagnetic significance. Investigatingthe relationship between these components and the magnetic carriers is important to distin-
