This work aimed to find the effect of cranberry extract (75 and 150 mg/kg·b·w) and vit. C (1 g/kg·b·w orally) on renal toxicity induced by Diclofenac sodium in male albino rats. Treated rats with diclofenac sodium with a concentration 150 mg/kg·b·w, expressed a significant increase in several parameters includes, plasma total cholesterol, LDL-cholesterol, and triglyceride as well as renal nitric oxide (NO), tumor necrosis factor-alfa (TNF-α) and TBARS. In addition, a significant reduction in renal superoxide dismutase (SOD), GSH, catalase (CAT) and plasma HDL. The present results explain that, using cranberry extract and vit. C resulted in increasing the level of GSH, CAT and SOD as well as gene expression of renal SOD, CAT and IL-22 and reduce the level of TBARs significantly which led to preventing renal tissue damage. Our results also revealed that cranberry extract can protect DNA from damage as obtained from comet essay. TM-U was elevated in DCLF treated group when compared with normal. However cranberry extract was able to reduce this elevation in dose dependant manner. Histological features in H&E taken to different groups also mirrors this findings. DCLF causes many changes in renal tissue include infiltration by inflammatory cells, attenuated glomeruli, apoptosis in tubular epithelia.

目的:通过节细胞内网状层(GCIPL)评估中度和重度青光眼的损伤程度并比较其与视盘周围视网膜神经纤维层(PRNFL)的诊断效能,包括敏感性与特异性及ROC曲线下面积(AUC)。方法:前瞻性研究。共210眼(包括中度青光眼患者30例54眼,重度青光眼患者34例59眼和正常人50例97眼)纳入本研究。所有参与者均接受全面眼科检查,包括视野检查、3D-OCT视盘检查和3D-OCT黄斑部垂直扫描。记录并比较所有参与者的GCIPL和PRNFL的AUC、敏感性与特异性。结果:在中度和重度青光眼组中,上部、下部及整体GCIPL和PRNFL厚度明显变薄(P<0.001)。在中度青光眼组中,GCIPL的敏感度与特异性高于PRNFL(仅上半部分敏感性相同)。重度青光眼组,上部、下部及整体GCIPL的敏感度均低于PRNFL。整体GCIPL的特异性低于PRNFL。上部GCIPL的特异性高于PRNFL。下部GCIPL的特异性与PRNFL相同。结论:对于区分中度和重度青光眼,黄斑GCIPL参数的功能远高于PRNFL。两者联合在病情分析中效果最优,能够提供更准确的损伤程度评估。
