Information on phosphorus(P) adsorption and its impacts on the redistribution of the P fraction in soil profiles are important for environmental management under intensive agricultural *** clarify the dominant factors influencing soil phosphorus adsorption in an Entisol(locally known as purple soil), P adsorption experiments were conducted in Sichuan Basin of southwestern China for cropland and woodland soils with acidic, neutral and calcareous origins throughout their profile. After various doses of P were added during incubation experiments, soil P fractions were also analyzed. The results showed that there were no significant differences in Fe-oxides and P adsorption along the vertical gradients. Agricultural practices and lower p H conditions reduced the P adsorption capacity of purple soils throughout the soil profiles. For acidic and neutral purple soil profiles, the P adsorption capability was mainly influenced by Fe-oxides and soil texture. Ca-bound P and Fe-Al-bound P represented the majority of the total inorganic P of calcareous *** was a saturation of adsorption capacity by sesquioxide and a high risk of dissoluble reactive P(NH_4 Cl-P) being released out of the soil profile in acidic and neutral purple soils after the greatest P addition, indicated by the higher proportions of NH_4 Cl-P(over 40%) and decreasing Fe-Al-P fraction.P fractions migrated with greater difficulty in calcareous purple soil profiles as Ca-P fraction peaked over 65% when adding a P dose at or greater than 80 g P kg^(-1), indicating the high potential of P *** X-Ray Diffraction analysis also verified the formation of brushite. Adaptive management practices should be designed to alleviate P losses for acidic and neutral purple soils.

Objective:To evaluate the efficacy of allicin combined with cyclophosphamide on neuroblastoma(NB)-bearing mice and explore the immunological mechanism in ***:A total of 30NB-bearing mice were equally randomized into model group,cyclophosphamide group and combined therapy group,10 nudemice were set as normal saline(NS) *** group and combined therapy group were weekly injected with 60 mg/kg cyclophosphamide for four weeks;besides,combined therapy group was given with allicin(10 mg/kg/d) by gastric perfusion for 4 weeks;model group and NS group were given with the same volume of *** VEGF content was detected by ELISA pre-treating(0 d) and on the 3rd d.14 th d and 28 th d;on29th d,all mice were sacrificed and the tumor,liver,spleen and thymic tissues were *** were made into paraffin section for detecting tumor cell apoptosis and proliferation by *** BrdU method,*** curves were drawn by Kaplan-Meier ***:After treatment,both treatment groups relieved on viscera indexes,VEGF level,T cell subsets distribution and tumor growth and each index of combined therapy group was better than cyclophosphamide group(P<0.05 or 0.01);only combined therapy group could significantly increase the lifetime of NB-bearing mice(χ~2=5.667,P=0.017).Conclusions:Allicin can improve T cell subsets distribution and inhibit VEGF expression through its immunomodulatory activity,thereby improve the efficiency on NB in coordination with cyclophosphamide.
