Objective To investigate the roles of somatostatin(SS)positive intemeurons in the development and compensation of temporal lobe epilepsy.Methods Piloearpine-induced epilepsy rat model was established.Immunohistochemistry method was used to detect number changes and axonal sprouting of SS positive intemeurons in different domains of the hippocampus at difierent time points.Degeneration of SS positive interneurons and their neurophils were detected by the double immunofluorescence staining with SS and Fluoro-Jade B(FJB)at 7 and 60 days after status epilepticus (SE).Results In the exoerimental rat group,the number of SS positive neurons decreased in each hippocampal domain,and it reached the lowest at 7 days post-SE(There were 11.1±3.3 in hilus,2.8±0.9 in CA1region and 1.8±0.7 in CA1region,t=13.519,9.644 and 8.808,all P<0.01).In chronic phase,the number of SS neurons gradually recovered,and exceeded the control group in CA1 area at 60 days post-SE(12.8±1.5 vs 8.8±1.3,t=-4.506,P<0.01),however,the number of SS neurons in the hilus(25.5±4.6)and CA1 area(4.8±0.8)remained significantly less than normal levels(t value were 4.691 and 3.953.both P<0.01).Increased SS positive fibers were found in the lacunosum-molecular (1m)layer and outer molecular layer of dentate gyrus after 30 days post-SE,and numerous SS positive fibers were seen threnghout the layers of area CA1 at 60 days post-SE.Double immunofluuorescence revealed that a few SS positive interneurons and fibers were also labeled by FJB in area CA1 at 7 days post-SE and in CA domain/hilus at 60 days post-SE.Conclusions SS intemeurons loss plays an important role in the development of temporal lobe epilepsy.The loss is partially caIlsed by the degeneration and death of neurons;SS positive neurophils increase within area CA1 in chronic phase may play a significant role in the generation and compensation of temporal lobe epilepsy. 相似文献

Objective To investigate the growth inhibition and radiosensitization of Celecoxib in hu-man nasopharyngeal carcinoma cell line CNE-2. Methods CNE-2 growth inhibition by Celecoxib was eval-uated by MTT method. Apoptosis-related changes in morphology were observed by transmission electron mi-croscopy (TEM). Cell cycle distribution and apoptosis rate were measured by flowcytometry (FCM). The ex-pression of COX-2 protein was observed by SP method after the treatment of Celecoxib. Cells were randomly planted into four groups: irradiation control(Ci), drug group(Cd), irradiation group(R), and Celecoxib plus irradiation group(D+R). Single irradiation of 2,4,6,8,and 10 Gy were administered for colonogenic assay. Cell cycle distribution and apoptosis rate were analyzed at 6 Gy irradiation. Results The growth of CNE-2 cell was inhibited by celecoxib in a dose-and time-dependent manner, the IC50 was 80 μmol/L After the treatment, cell ratio of GO and G, phases was increased (47.03±2.76 vs 56.17±1.95, t=4.68, P= 0.010), whereas the ratio of S and G2/M phases was decreased (33.07±1.86 vs 24.87±1.76, t=5.54, P = 0.010; 19.30±0.53: 17.73±0.83, t=2.75, P=0.050), and the apoptosis rate was increased (1.57±0.47:10.47±0.31, t = 27.39, P = 0.000) in a dose-dependent manner. Apoptosis with nuclear chromatin condensation, fragmentation and cell shrinkage was found by TEM. SP method showed that Celeib decreased COX-2 expression (17.48±0.34 vs 12.82±0.51,t=13.20,P =0.00). The sensitivity ratio(D0) was 1.15. FCM showed that the percentage of cells in G2/M phase was significanty more in R and D+R groups than in Ci and Cd groups (68.00±1.65,54.27±5.74,17.60±0.80,14.86±1.23, t=47.70,P=0.000; t=11.63, P=0.000), and also significantly different between R group and D + R group (t=3.99, P= 0.020). The apoptosis rate was higher in R and D + R groups than Ci and Cd groups(4.83±0.97,9.50± 1.35,1.33±0.86 and 2.28±0.42,t=4.67,P=0.010;t=8.81, P=0.000), D + R group than R group(t =4.85,P=0.010). Conclusions Celecoxib can markedly inhibit the growth and induce apoptosis in CNE-2 cells,which may depend on COX-2 pathway. Celeeoxib potently enhances the radiosensitivity of CNE-2 cells,which may due to the repair inhibit of radiation-induced DNA damage, inhibit of cell proliferation,and enhancement of cell apoptosis after irradiation. 相似文献

目的探讨脊髓损伤后短期内小鼠肠道功能的变化。方法将105只昆明种小鼠随机分为正常组(A组,n=30)、假手术组(B组,n=30)和模型组(C组,n=45)。A组不作处理,B组仅暴露脊髓,不夹持。C组采用动脉瘤夹夹持T10处脊髓,复制脊髓损伤模型。分别于术后12 h、24 h、48 h测定小鼠回肠肌电慢波及平滑肌收缩力,并做回肠HE染色。结果脊髓损伤后12 h、24h、48 h,C组小鼠肌电频率和振幅低于A组和B组(P0.05),收缩力振幅低于A组和B组(P0.05),但24 h、48 h后收缩力频率高于A组和B组(P0.05)。C组各时间点肠黏膜评分均较A组和B组高(P0.05)。结论小鼠脊髓损伤后早期,肠道平滑肌肌电活动减弱,收缩力减小,肠黏膜轻度损伤。 相似文献

目的探讨原发性肾上腺淋巴瘤的临床表现及诊疗方法。方法总结我院收治的1例原发性肾上腺淋巴瘤患者的临床表现及诊疗方法,并回顾性分析国内外文献资料。结果患者在全身麻醉下行右侧肾上腺肿瘤根治术+右叶肝部分切除术+膈肌修补术,取病理活检结果为(右肾上腺区、肝)弥漫性大B细胞淋巴瘤,术后使用RCHOP方案规律化疗8次,随访1年患者已完全缓解,未见复发征象。结论原发性肾上腺淋巴瘤是临床少见的恶性程度高的肿瘤,主要以弥漫大B细胞淋巴瘤多见,早期无明显特异性,且缺乏典型临床表现,临床上易误诊,一旦确诊,应及早手术并化疗以减缓疾病进展及减轻患者痛苦。 相似文献
