通过合成反应制备了P407-P188泊洛沙姆和磺化壳寡糖复合温敏凝胶并负载aFGF,用于对aFGF进行缓释保护。SEM结果表明该复合温敏凝胶呈疏松多孔,层状分布,有助于吸附aFGF蛋白。体外释放实验结果表明在5d以后,aFGF的释放基本呈缓慢持续增长... 通过合成反应制备了P407-P188泊洛沙姆和磺化壳寡糖复合温敏凝胶并负载aFGF,用于对aFGF进行缓释保护。SEM结果表明该复合温敏凝胶呈疏松多孔,层状分布,有助于吸附aFGF蛋白。体外释放实验结果表明在5d以后,aFGF的释放基本呈缓慢持续增长,说明复合温敏凝胶具有缓控释放的效果。生物相容性评价表明aFGF磺化壳寡糖温敏凝胶在小鼠体内存在异物性,但并没有毒性和抗原性,且具有良好的生物相容性。 展开更多

To investigate the pharmacokinetic characteristics of moclobemide sustainedrelease tablets after multiple oral dose administration in healthy Chinese volunteers. MethodsMoclobemide sustained release tablets were given as a multiple oral dose regimen of 300 mg oncedaily for five consecutive days to 12 healthy volunteers. The concentrations of moclobemide inplasma were determined by reversed-phase high performance liquid chromatography. The partialpharmacokinetic parameters were calculated using 3p97 pharmacokinetic program. Results Theconcentration-time profile fitted an one-compartment model best. The steady-state pharmacokineticparameters of moclobemide sustained release tablets after multiple oral doses were as follows:C_(max) was (1 950 +- 156) μg· L^(-1), T_(max) was (6.00 +-1.55) h, T_(1/2(kel)) was (3.14 +-0.12)h, AUC_(ss 0-24) was (22 836 +- 1 842) μg·h· L^(-1), MRT was (7.68+-0.36) h, CL/F_((s)) was(20.2+-2.1) L·h^(-1), and V/F_((c)) was (91.4+-9.4) L, respectively. No marked adverse events werenoted during this study. Conclusion The formulation has a sustained-release effect and goodtolerance in the healthy volunteers, which provides useful information for clinical practice. 展开更多

[Objective] The aim was to get a high yield and simplify fertilization of summer corn in moisture soils in the east of Henan province. [Method] Effects of slow-release fertilizers special for summer corn on its yield, economic benefits and resistance. [Result] By the slow-release fertilizers containing 45% slow-release nitrogen, thousand-kernel weight and the number of ear went up by 28 g and 16 kernels, respectively. Slow-release fertilizers advanced nutrient uptake by summer corns and kept soil nitrogen balanced. In comparison to local fertilization approach, corn yield grew by 13.5% and net profit went up by 1 920 yuan/hm^2 by same-term application technique of seed & slow-release fertilizer in comparison to local methods. In comparison to normal fertilizers containing the same-quantity nutrients, corn yield grew by 10.3% and net profit by 1 215 yuan/hm^2. [Conclusion] The research provides references for slow-release fertilizer promotion in production of corn in Zhoukou and innovation and integration between agricultural machines and techniques. 展开更多
