Gentamicin is a member of Aminoglycosides which has represented highly effective antimicrobial agents especially in Gram-negative infections despite their toxic effects in the kidney.Rapid diagnosis is vital to preserve renal function and to slow down renal injury.Owing to the poor sensitivity and specificity of serum creatinine (SCr) and blood urea nitrogen (BUN),new biomarkers for earlier and more accurate detection are needed.The aim of our study was to determine whether kidney injury molecule-1 (KIM-1) and neutrophil gelatinase-associated lipocalin (NGAL) may be useful biomarkers in the assessment of Gentamycin-induced Nephrotoxicity in rats.In this study,the two biomarkers of renal toxicity was assessed via quantitative real-time PCR and immunohistochemistry in rats treated with Gentamicin for up to 7 days.Repeated administration of Gentamicin to male SD rats for 1,3,or 7 days resulted in a dose- and time-dependent increase in the expression of KIM-1 and NGAL.Changes in gene and protein expressions were fo und to correlate with the progressive histopathological alterations and preceded effects on traditional clinical parameters indicative of impaired kidney function.Both of the biomarkers are supported to be used as sensitive indicators of acute kidney injury caused by Gentamicn.

目的:蚕蛹油中含有较高的胆固醇,本文采用物理吸附法,比较了不同吸附剂对脱除蚕蛹油胆固醇的影响,优化了其工艺,可以有效提高蚕蛹油的保健价值.方法:物理吸附法.结果表明,在所研究的7种吸附剂中,酸性氧化铝对蚕蛹油中胆固醇的吸附能力最强,而对蚕蛹油本身性质影响小.当酸性氧化铝添加量为19％、作用时间3 小时,作用温度60℃时,对蚕蛹油中胆固醇的脱出率达到40％以上.结论:酸性氧化铝在一定条件下能较好的降
对蚕蛹源ACE抑制肽的稳定性进行了研究,并通过Lineweaver–Burk 双倒数曲线作图和紫外光谱初步探讨了蚕蛹源ACE抑制肽对ACE 的抑制机理.结果表明:蚕蛹源ACE抑制肽在高温、酸性和碱性条件下不稳定,易失活;冷冻干燥和喷雾干燥对蚕蛹源ACE抑制肽的活性影响较小;蚕蛹源ACE抑制肽对胃蛋白酶、胰蛋白酶和α-胰凝乳蛋白酶具有较强的抗消化能力,经胃蛋白酶、胰蛋白酶和α-胰凝乳蛋白酶共同消化后
为了开发蚕蛹油提取新工艺,以蚕蛹为原料,采用超声波辅助中性蛋白酶水解法提取蚕蛹油.在单因素试验的基础上,以蚕蛹油提取率为响应值,用响应面分析法研究了超声波功率、底物浓度和加酶量对蚕蛹油提取率的影响,并通过气相色谱对蚕蛹油的脂肪酸组成进行了分析.结果表明:各因素对蚕蛹油提取率影响从大到小依次为:底物浓度、加酶量、超声波功率.超声波辅助水解法提取蚕蛹油的最优工艺条件为:底物浓度68.2g/L,超声波功
为了研究蚕蛹蛋白ACE抑制肽的结构特征,采用超滤、DEAE-52离子交换色谱和Sephadex G-50凝胶色谱对蚕蛹蛋白酶解产物进行分离纯化,并利用液质联用对蚕蛹蛋白ACE抑制肽的结构特征进行初步分析.试验结果表明:分离得到的组分2(IC50＝0.072 mg/mL)的ACE抑制活性较高,是分离纯化前的2.95倍,为蚕蛹蛋白ACE抑制肽的主要组分;组分2中ACE抑制肽的分子量为226.34～98
