Pegylated interferon-alpha plus taurine in treatment of rat liver fibrosis

AIM: To investigate the antif ibrotic effects of peginterferon- alpha 2b and taurine on oxidative stress markers and hepatocellular apoptosis. METHODS: Sixty rats with CCl4-induced liver fibrosis were divided into 4 groups (n = 15). Group 1 was left for spontaneous recovery (SR). Groups 2-4 received peginterferon-alpha 2b, taurine, and their combination, respectively, for four weeks. Histological f ibrosis scores, histomorphometric analysis, tissue hydroxyproline, tissue MDA, GPx and SOD activities were determined. Activated stellate cells and hepatocellular apoptosis were also evaluated. RESULTS: The degree of f ibrosis decreased in all treatment groups compared to spontaneous recovery group. Taurine alone and in combination with peginterferon-alpha 2b reduced oxidative stress markers, but peginterferon-alpha 2b alone did not. Apoptotic hepatocytes and activated stellate cells were higher in groups 2-4 than in group 1. Combined taurine and peginterferon-alpha 2b further reduced fibrosis and increased activated stellate cell apoptosis, but could not improve oxidative stress more than taurine alone.CONCLUSION: Peginterferon-alpha 2b exerts anti- f ibrotic effects on rat liver fibrosis. It seems ineffective against oxidative stress in vivo. Peginterferon-alpha 2b in combination with taurine seems to be an antif ibrotic strategy.

Combination of allopurinol and hyperbaric oxygen therapy:A new treatment in experimental acute necrotizing pancreatitis?

瞄准：在试验性的老鼠在生物化学、组织病理学说的变化，氧化压力，和细菌的易位(BT ) 上调查 allopurinol 和高比重的氧(HBO ) 治疗的单个、联合的效果尖锐胰腺炎(AP ) 。方法：85 只 Sprague-Dawley 老鼠在学习被包括。85 只老鼠中的十五个被用作控制(假冒，组我) 。AP 在留下经由管内牛磺胆酸盐注入被导致七十只老鼠。幸存到尖锐引起坏死胰腺炎的正式就职的老鼠被使随机化进四个组。组 II 独自收到了 saline，组 III allopurinol，加 HBO 的组 IV allopurinol 和组 V HBO。浆液淀粉酶层次，氧化压力参数， BT 和组织病理学说的分数是坚定的。结果：浆液淀粉酶层次在与组 II 相比的组 III， IV 和 V 是更低的(974 +/- 110， 384 +/- 40， 851 +/- 56，和 1664 +/- 234 U/L，分别地 P 【 0.05，为所有) 。联合揭示的二种处理选择显著地降低 median [25-75 百分位数] 组织病理学说的分数什么时候与单个政府相比(13 [12.5-15 ] 在 allopurinol 组， 9.5 [7-11.75 ] 在 HBO 组，并且 6 [4.5-7.5 ] 在联合的组， P 【 0.01 ) 。氧化压力标记在与控制相比的所有处理组显著地更好。进胰和 mes 伤寒淋巴结的细菌的易位在与组 II 相比的组 III ， IV 和 V 是更低的(54%，23%，50%对为到胰的易位的100%，并且62%，46%，58%对为到 mes 伤寒淋巴节点的易位的100%，分别地 P 【 0.05 为所有)。结论：当在试验性的老鼠 AP 独立管理了时，现在的学习证实 HBO 和 allopurinol 处理的利益。这些处理选择的联合看起来更有效地阻止胰腺的损害参数的前进。

What is the relationship between frailty and orthostatic hypotension in older adults?

Background Frailty and orthostatic hypotension (OH),which is common in older adults,is associated with morbidity and mortality.The relationship between them remains unclear.The aim of the study is to determine whether there is a relationship between frailty and OH.Methods A total of 496 patients who were admitted to the geriatric clinic and underwent comprehensive geriatric assessment were retrospectively reviewed.In a cross-sectional and observational study,OH was measured by the Head-up Tilt Table test at 1,3,and 5 min (respectively,OH1,OH3,and OH5) and the frailty was measured by the Fried’s frailty scale.Results The mean age of all patients was 75.4 ± 7.38.The prevalence of females was 69.8%.When the frail people were compared with the pre-frail and the robust ones,the frailty was associated with OH1.There was no relationship between the groups in terms of OH1 when the pre-frail group was compared with the robust group.OH3 were higher in the frail group than in the pre-frail group (P < 0.05) and the OH5 were higher in the frail group than in the pre-frail and robust group (P < 0.05),but OH3 and OH5 were not associated with frailty status when they were adjusted for age (P > 0.05).Slowness and weakness were associated with OH1 (P < 0.05),whereas the other components of the Fried’s test were not.Conclusions Frailty may be a risk factor for OH1.The 1^st min measurements of OH should be routinely evaluated in frail older adults to prevent OH-related poor outcomes.
