This experiment was conducted to investigate the liver-protective effect of Chinese herbal compound probiotics (CHCP) on acute liver injury layers.One hundred and eight 1 day old hens were divided into 4 groups with 3 replicates in each group and 9 layers per replicate in trial 1.The layers in model groups Ⅰ to Ⅲ were gavaged with 10% (V/V) soybean oil solution of carbon tetrachloride (SCCl4) according to 1,2 and 4 mL/(kg·BW) at 14,28 and 35 d,respectively.The layers in control group were gavaged with 2 mL/(kg·BW) soybean oil.In trial 2,sixty 1 d layers were divided into 5 groups:Control group (soybean oil),model control group(SCCl4)and low-dose,middle-dose and high-dose CHCP group (SCCl4+1‰ CHCP,SCCl4+2‰ CHCP and SCCl4+4‰ CHCP respectively).CHCP were used by drinking water since 7 days.SCCl4 were gavaged according to 2 mL/(kg·BW) at 14 and 28 d.The results showed as follows:The model of layers liver damage could be built by intragastric administration of 2 mL/(kg·BW) 10%(V/V) SCCl4 at 14,28 d respectively,with the signs of hepatic steatosis,severe vacuolar degeneration,nuclear condensation and necrosis.Compared to the model control group,the serum AST levels in low,medium and high dose CHCP groups were decreased by 4.35% (P > 0.05),7.57% (P > 0.05) and 9.79% (P < 0.05),the serum ALT levels in medium and high dose CHCP groups were decreased by 34.92% (P < 0.01),36.51% (P < 0.01),the serum total bilirubin content in medium and high dose CHCP groups were decreased by 25.49% (P < 0.01),27.45% (P < 0.01).The liver cell congestion was reduced to varying degrees in different dose CHCP groups,and the liver cell had no vacuoles,arranged in neat rows,abundant cytoplasm and uniform in different dose CHCP groups.In conclusion,2‰,4‰ CHCP could reduce hepatocyte necrosis,decrease the serum activities of ALT,AST and total bilirubin levels,and had protective effect on hepatic injury induced by SCCl4.  相似文献

为了提高难溶性药物烯丙孕素(altrenogest,ALT)的水溶性,本试验采用冷冻干燥法来制备烯丙孕素-羟丙基-β-环糊精(ALT-HP-β-CD)及其衍生物2,6-二甲基-β-环糊精(DIME-β-CD)包合物载药体系,并对ALT的线性关系和专属性、仪器的精密度以及包合物的回收率和稳定性进行了测定。以包合物的收率和包合物中ALT的包合率为评价指标,采用正交试验设计优选2种包合物的最佳制备条件,并使用傅里叶变换红外光谱法、热重分析法和显微镜成像法对所制得的ALT包合物进行表征分析,采用溶解度法测定包合物中ALT的溶解度。结果表明,ALT在1~12 μg/mL范围内具有较好的线性关系且专属性良好,仪器的精密度良好;加入0.1、0.2和0.3 mL ALT标准液的ALT-HP-β-CD包合物的平均回收率分别为97.78%、99.38%和99.90%,加入0.1、0.2和0.3 mL ALT标准液的ALT-DIME-β-CD包合物的平均回收率分别为93.86%、97.72%和94.93%;ALT-HP-β-CD包合物的最佳制备工艺为在55 ℃条件下,ALT与HP-β-CD的投料摩尔比为1∶7,包合时间为4 h,溶液pH为8,溶剂水的加入量为110 mL/g药物;ALT-DIME-β-CD包合物的最佳制备工艺为在55 ℃条件下,ALT与DIME-β-CD的投料摩尔比为1∶4,包合时间为4 h,溶液pH为9,溶剂水的加入量为100 mL/g;经傅里叶变换红外光谱法、热重分析法和显微镜成像法表征,证实成功制得包合物;溶解度试验得出包合物的溶解度分别约为ALT原药的1 012和1 354倍,表明两种包合物均可有效增加ALT的溶解度。本试验包合物的制备方法简单,条件温和,易于产业化生产。  相似文献

目的通过测定慢性丙型肝炎病毒(HCV)感染患者外周血淋巴细胞CD8 、CD38 的表达,从而了解感染者机体细胞免疫状态。方法流式细胞术检测44例慢性HCV感染者及正常对照外周血ALT、外周血淋巴细胞CD8 、CD38 细胞的百分率。结果慢性HCV感染者外周血CD8 、CD38 、CD8 CD38 细胞比例均明显高于正常对照组(P<0.01)。慢性丙型肝炎各组之间比较,ALT异常组CD8 、CD38 、CD8 CD38 细胞比例高于ALT正常组(P<0.01)。结论慢性HCV感染患者CD8 、CD38 、CD8 CD38 细胞比例明显升高,表明慢性HCV感染者处于较高的细胞免疫状态,与肝功能损伤有一定的相关性,对指导临床的病情分析和诊断具有参考价值。  相似文献

目的:探讨慢性乙型肝炎患者血清胆碱脂酶(CHE)活性水平与肝组织炎症病理分级(G)的关系。方法:采用RI-1000TM全自动生化分析仪检测106例经病理证实的慢性乙型肝炎患者血清胆碱脂酶(CHE).丙氨酸转氨酶(ALT)和天冬氨酸转氨酶(AST)活性水平.统计分析血清ALT、AST、CHE水平与肝组织病理炎症分级(G0~G4)的关系。结采:血清CHE水平随着肝组织炎症活动度增高而降低,而ALT、AST水平随着肝组织炎症活动度增高而升高;G4级患者的血清CHE水平明显低于G1、G2、G3级患者,G3级低于G1、G2级.差异有显著性(P〈0.05或0.01)。G4级患者的血清AST水平明显高于G1、G2、G3级患者.但G1、G2、G3级患者AST水平以及各炎症分级之间ALT水平差异无显著性(P〉0.05)。结论:CHE比ALT、AST更能反映肝损害的严重程度、是一项有意义的无创性指标。  相似文献

2020年在湖南大通湖区按照裂区设计进行大田试验,以水稻品种泰优390和H优518为材料,设常规机插秧(T1)、人工手抛秧(T2)和精量有序机抛秧(T3)三种处理,观察测定不同种植模式下的秧苗素质、产量及其构成因素、茎蘖动态和生育期,以探究不同种植方式对寒露风影响下晚稻生长发育特性、产量及产量构成的影响,找出在寒露风影响下更具有稳产减灾效果的种植方式,并对其减灾机理进行探究,为水稻生产和防灾减灾策略提供理论依据。结果表明:(1)采用钵苗育秧技术培育秧苗的精量有序机抛种植模式的秧苗素质相对较好,与采用毯苗育秧技术育秧的机插种植模式的秧苗素质差异显著。(2)移栽后,精量有序机抛秧返青最快,分蘖发生最早。(3)精量有序机抛秧的水稻生育期较手抛秧、机插秧显著缩短,品种泰优390可缩短生育期4~12d,H优518可缩短生育期3~8d。(4)在寒露风影响下,精量有序机抛秧的水稻成穗率、结实率、收获指数、单位面积有效穗数、千粒重及产量较手抛秧、机插秧高,且与机插秧处理差异达到显著水平。品种泰优390和H优518精量有序机抛秧的产量分别比手抛秧、机插秧增产21.7%、273.5%和12.9%、19.6%。研究结果说明使用精量有序机抛方式育出的秧苗素质较高,移栽大田后返青较快,分蘖速率较快,后期分蘖下降幅度小,有效穗数、结实率、千粒重较高,比人工手抛秧、常规机插秧更能促进水稻产量的提高。综合气候条件考虑,使用精量有序机抛方式能缩短晚稻生育期,在冷害严重的年份具有明显减灾效果。  相似文献

The suitability of the Spotchem 4430 benchtop biochemistry analyzer for canine blood samples was tested for creatinine, glucose, proteins, urea, alkaline phosphatases and alanine aminotransferase. Results obtained from whole blood and corresponding heparin plasma were identical except for proteins which were higher in plasma (n=10). Between series imprecision (n=10) was <5% for substrates and <10% for enzymes. Comparison of results from 100 Li-heparin samples with those measured with a Vitros 250 analyzer showed good correlation (r>0.93). The slopes of the Passing-Bablock's regression ranged from 0.90 to 1.20 and intercepts were low. The mean biases were low, except for creatinine for which the results obtained by Spotchem (Jaffe reaction) were about 20 micromol/L higher than with the Vitros (enzymatic reaction). The results of this study show that the Spotchem analyzer is suitable for use in canine whole blood or plasma when small numbers of tests are to be performed and large analyzers are not available.  相似文献

Rheum palmatum Linn has been widely applied in the clinical treatment of diabetes mellitus. It has been found that emodin as the major bioactive component of R. palmatum L exhibits the competency to activate peroxisomal proliferator-activated receptor-γ (PPARγ) in vitro. So the aim of this study was to evaluate the anti-diabetic effects of emodin through the activation of PPARγ on high-fat diet-fed and low dose of streptozotocin (STZ)-induced diabetic mice. The diabetic mice were intraperitoneally injected with emodin for three weeks. No changes of food consumption and the body weight in emodin-treated mice were monitored daily during the entire experiment. At the end of experiment, the levels of blood glucose, triglyceride and total cholesterol in serum were significantly decreased after emodin treatment. However, serum high-density lipoprotein cholesterol (HDLc) concentration was significantly elevated. The glucose tolerance and insulin sensitivity in emodin-treated group were significantly improved. Furthermore, the results of quantitative RT-PCR analysis showed that emodin significantly elevated the mRNA expression level of PPARγ and regulated the mRNA expressions of LPL, FAT/CD36, resistin and FABPs (ap2) in liver and adipocyte tissues. No effects on the mRNA expressions of PPARα and PPARα-target genes were observed. Taken together, the results suggested that the activation of PPARγ and the modulation of metabolism-related genes were likely involved in the anti-diabetic effects of emodin.  相似文献

为了利用血清学方法检测熊的肝脏疾病,采用肝功能试验的方法,对黑熊棕熊血清总蛋白TP(Serum total protein)、血清白蛋白A(Albumin)、G血清球蛋白(Globulin)、血清丙氨酸氨基转移酶ALT(Alanine aminotrans ferase)进行了测定。结果表明:32只被检测的黑熊、棕熊中,患有肝脏疾病的5只熊,ALT平均值为105.9;健康熊25只ALT平均值21.24。患病组与对照组ALT的μ0.01=2.576,差异显著。丙氨酸氨基转移酶ALT对检测熊的肝脏疾病有决定意义。  相似文献
