神经肽Y对实验性变态反应性脑脊髓炎豚鼠血清白介素水平的影响

目的观察神经肽Y(NPY)对实验性变态反应性脑脊髓炎(EAE)豚鼠血清白介素(IL)水平的影响。方法30只豚鼠随机分为正常对照组、EAE组、NPY组;NPY组制模前侧脑室注射NPY;预处理1周后将大鼠脊髓匀浆注入EAE组及NPY组豚鼠足垫制作EAE模型;每日进行神经功能障碍评分;观察造模后各组EAE发病率、发病潜伏期;在病情高峰期检测各组豚鼠血清IL-1β、IL-2、IL-4、IL-6、IL-8水平,并进行神经组织病理学检查。结果(1)EAE组及NPY组发病率分别为100%和90%;发病潜伏期分别为(10.0±4.8)d和(25.4±12.6)d;病情高峰期神经功能障碍评分分别为(3.60±0.52)分和(1.80±1.14)分;两组间差异有统计学意义(均P<0.01)。(2)与正常对照组比较,EAE组和NPY组豚鼠病情高峰期血清IL-1β、IL-2、IL-6、IL-8水平明显升高,IL-4水平明显降低(均P<0.05);与EAE组比较,NPY组病情高峰期血清IL-4水平明显增高,IL-2水平明显降低(均P<0.05)。(3)神经病理学检查显示NPY组神经组织血管周围炎症细胞浸润和髓鞘脱失改变较EAE组明显减...

Effects of neuropeptide Y on levels of serum interleukins in guinea pigs with experimental allergic encephalomyelitis

Objective To observe the effect of neuropeptide Y(NPY) on the levels of serum interleukins(ILs)in guinea pigs with experimental allergic encephalomyelitis(EAE).Methods 30 guinea pigs were divided randomly into normol control group,EAE group and NPY group.The NPY was injected into the intracerebroventricular in NPY group one week before the EAE model be made.The EAE molders were made by injecting the homogenate of rat's spinal cord into the plantar of guinea pigs in groups EAE and NPY.Then,the neurological d...
