Investigating the role of~(99m)Tc-TRODAT-1 SPECT imaging in idiopathic Parkinson's disease

Objective:To investigate the role of ~(99m)Tc-TRODAT-1 SPECT in diagnosis and assessing severity of idiopathicParkinson's disease(PD).Methods:Thirty-eight patients with primary,tentative diagnosis of PD and eighteen age-matchednormal controls were studied with ~(99m)Tc-TRODAT-1 SPECT imaging.The regions of interests(ROIs)were drawn manually oncerebellum(CB),occipital cortex(OC)and three transverse plane slice-views of striatums,the semiquantitative BG(back-ground)/[(OC CB)/2]were then calculated.Results:A lower uptake of ~(99m)Tc-TRODAT-1 in striatums were displayed inthirty-six out of thirty-eight PD patients by visual inspection,compared to controls.In twenty-four PD cases with HYS(Hoehn andYahr scale)stage Ⅰ,a greater loss of DAT uptake was found in striatum and its subregions contralateral striatum to the affectedlimbs than in the same regions of the controls,although the striatal uptake was bilaterally reduced.Using Spearman correlationanalysis showed that the reduction of the uptake ratios signifi     

蓝花参内生真菌的初步分离鉴定

为探索蓝花参（Wahlenbergia marginata（Thunb．）A．DC．）内生真菌的种类,对蓝花参植物的茎、叶进行内生真菌的分离纯化,获得10株内生真菌,表明蓝花参内生真菌的多样性较为丰富;其中产孢特征明显的4株经形态学鉴定分别属于大果粗孢曲霉属（Liliputia Boud．et Pat．）、链格孢属（Alternaria Nees）、裂殖酵母属（Schizosaccharomyces Linder）双足囊菌属（Dipodascus Lagerh．）。
