为提高长江流域棉区棉花群体光合有效辐射(PAR)利用率并塑造合理群体结构,本研究设置不同播期(B1:5月13日、B2:5月25日)和种植密度(M1:7.5万株·hm-2、 M2:9.0万株·hm-2、M3:10.5万株·hm-2、 M4:12.0万株·hm-2),研究不同栽培方式对棉花冠层PAR时空分布的影响。结果表明,在一定生育时期内,B1播期处理棉花冠层对PAR的截获能力较强;在同一播期条件下...
Par-1受体激动剂对神经病理性疼痛大鼠血浆内啡肽的影响
SD大鼠 神经病理性疼痛 蛋白酶激活受体 内啡肽
2020/11/23
探讨蛋白酶激活受体 1 (PAR-1)激动剂对神经病理性疼痛(NP)大鼠血浆内啡肽的影响。方法 选取SD大鼠64只,采用随机数表法分为正常对照组、假手术组(Sham组)、坐骨神经慢性结扎损伤(CCI)组和CCI+PAR-1组,每组16只。CCI大鼠建模:结扎左坐骨神经中段,假手术组只钝性分离肌肉,使坐骨神经充分暴露而不结扎。术后第8天测定各组大鼠机械触压痛阈,并分别于术后8 d采集各组大鼠下腔静脉...
