[Landscape pattern and its dynamics in typical oasis-desert transitional zone of Minqin Region in 1960-2005].

By using ERDAS and GIS techniques, a systematic analysis was made on the landscape pattern and its dynamics in typical oasis-desert transitional zone of Minqin Region in 1960-2005. Forest land and cultivated land were the dominant factors leading to the landscape change. During the research period, oasis expanded toward the periphery by 2-3 km, and the transitional zone moved toward desert, with its width increased from 4 km in 1960 to about 9 km in 1987 and decreased rapidly then.

The antitumor and antioxidative activities of polysaccharides isolated from Isaria farinosa B05.

The water-soluble intra-polysaccharides WIPS1 and water-soluble extra-polysaccharides WEPS1 were isolated from Isaria farinosa B05 through ethanol precipitation and gel permeation chromatography (GPC). Their characteristics were determined by chemical analysis, gas chromatography, GPC and IR spectroscopy. The results show that WIPS1 contained 90.

[Induction of CuZn-SOD mRNA expression and activity by PGMS in rat liver].

Aim: To study the effect of propylene glycol mannate sulfate (PGMS) on induction of CuZn-SOD.

Methods: Wistar rats were given PGMS p.o.

[Effect of propylene glycol mannate sulfate on blood lipids and lipoprotein lipase in hyperlipidemic rat].

Aim: To study the effect of propylene glycol mannate sulfate (PGMS) on blood lipids and lipoprotein lipase in hyperlipidemic rat, and its anti-hyperlipidemic mechanism.

Methods: PGMS was administered ig at different doses (37.8 mg.

[Expression of androgen receptor protein in hormone refractory prostate cancer].

Background & Objective: It was reported that androgen receptor (AR) gene amplification was found in hormone refractory prostate (HRPC) and it has been thought to be a possible molecular mechanism for the treatment failure. In this article, the expression of AR protein before and after hormone therapy was examined quantitatively in order to further clarify the relationship between AR expression and the genesis of HRPC.

Methods: AR protein content was determined using radioligand binding assay before and after hormone therapy in 28 patients with advanced prostate cancer.
