The catalytic effect of ruthenium on the oxidation reacti on of methylene blue (MB) was investigated and applied for the determination of ruthenium(Ⅲ) by the kinetic spectrophotometry in the sulfuric acid medium at 90±0.5℃. The optimum reaction conditions, kinetic parameters and r eaction mechan ism were studied. The linear ranges for the determination of ruthenium (Ⅲ) were 0.0～1.2 and 1.2～5.6 μg/L with a detection limit of 0.05 μg/L . Almost no foreign ions more than 50-fold concentration of Ru(Ⅲ) I nterfered with the determination. The method, which was of high sensitivity, good selectivity and stability, was s uccessfully applied for the determination of trace ruthenium in some ores and m e tallurgical products, the RSD (n=8) was 1.3%～2．2％ and the recovery was between 99% and 105%.

OBJECTIVE:To find out the general rule in ware-house-in inspection for Chinese medicinal crop.METHO_ DS:135reports of consigned inspection for Chinese medicinal material were quantitatively analysed in linking with the pre?served specimens.RESULTS:Main specimens inspected included Radix Morindae Officinalis,Bulbus Fritillariae Cirrhosae,Herba Cistarchis and Semen Cuscutae.The main cause of those unqualified Chinese medicine was due to fake and impure ma?terials adulterated.The target items of adulteration were herbal pieces and other small size Chinese medicinal materi?als.CONCLUSION:Chinese medicine should be purchased from the source of original unprocessed materials.During taking delivery of goods,formal differentiation and scientific inspection process should be performed to prevent fake and unqualified medicine being stored and used,to ensure the product quality up-to-standard.

OBJECTIVETo probe into effects of acupuncture on rehabilitation of nervous functions in the stroke patient of different OCSP types.

METHODSThe stroke patients were randomly divided into 4 subtypes (LACI, TACI, PACI, POCI) based on the OCSP clinical classification. The patients of every subtype were randomly sub-divided into an observation group and a control group. The patients in the 2 groups were treated with routine western medicine, and acupuncture at Baihui (GV 20), Sanyinjiao (SP 6), Taixi (KI 3), Xuehai (SP 10), etc. were added with reinforcing and reducing manipulation in the observation group and without manipulation of the needle in the control group. They were assessed with daily living ability scale (BI) at the time of enrollment, the end of 1, 3, 6, 12 months after the stroke, respectively.

RESULTSThere was no significant difference between the two groups for BI in LACI (P>0.05); there were significant differences 3, 6 and 12 months after the stroke between the two groups in PACI, POCI (P<0.05); in the TACI, there was a significant difference between the two groups for BI 3 and 6 months after stroke (P<0.05), with no significant difference 12 months after stroke (P>0.05).

CONCLUSIONAcupuncture has different effects on rehabilitation of daily living function in the stroke patient of different OCSP types.
