Background: Osteoarthritis (OA) is a disabling disease that can affect 6% to 12% of the adult population and more than a third of people over 65 years of age. Purpose: To assess whether a group of people with hand osteoarthritis (hOA) who received different types of treatment improved their function after two years of follow-up. Method: The entire sample (n = 97) underwent three follow-up assessments regarding anthropometric parameters of the upper limbs and ability to perform functional activities. Subsequently, the sample was divided into two groups for the intervention periods, called the First Period (n = 73) and the Second Period (n = 24);the First Period kept the same protocol with orientations, and the Second Period went to an intervention with orientation strength exercises and use of orthosis. Findings: In the separate analysis of the three questions of the DASH pain module, no differences were found between the assessment moments for groups of guidelines, treatment, or symptoms. Significant effects were observed for F(2, 162) = 3.5, p = 0.033, η2 = 0.04, and interaction for moments and intervention F(2, 162) = 4.3, p = 0.016, η2 = 0.05. Implications: It can be concluded that only guidance treatment does not benefit patients with hand osteoarthritis. In contrast, guidance, exercise, and orthosis treatment can significantly improve the disease.

The present study aimed to determine whether natural dehydrated feed (DNF) can replace dry extruded feed while preserving the required daily intake, nutrient digestibility and benefits for immunity and antioxidant response in cats. The animals were divided into two groups of seven animals each. One group received DNF, and the other consumed commercial extruded dry feed (DCF). The experiment lasted 45 days and we measured daily consumption and collected blood and feces samples. The animals in the DNF group showed greater digestibility of fiber and mineral matter than DCF. Cats in the DNF group had a higher volume of feces. DNF cats had lower leukocyte and granulocyte counts and cholesterol levels. Serum enzymatic antioxidant responses and non-enzymatic were higher in DNF cats. Cats in the DNF group showed lower serum acute phase proteins in addition to a tendency toward a higher concentration of transferrin than in the DCF group. Fecal Escherichia coli and total coliform counts of cats fed DNF were higher than DCF. We conclude that the daily consumption of cats is adequate. This feed had greater digestibility of fiber and mineral matter, in addition to an improvement in antioxidant and immunological responses.

In the first experiments, mangiferin （3 mg/kg, 10 mg/kg, 30 mg/kg, and 100 mg/kg, po） or tegaserod （1 mg/kg, ip） were administered 30 min before the char- coal meal to study their effects on normal transit. In the second series, mangiferin （30 mg/kg） was tested on delayed GIT induced by several different pharma- cological agonists （morphine, clonidine, capsaicin） or antagonists （ondansetron, verapamil, and atropine） whereas in the third series, mangiferin （30 mg/kg, 100 mg/kg and 300 mg/kg） or tegaserod （1 mg/kg） were tested on 6 h fecal pellets outputted by freely fed mice. The ratio of wet to dry weight was calculated and used as a marker of fecal water content. RESULTS： Mangiferin administered orally significantly （P 〈 0.05） accelerated GIT at 30 mg/kg and 100 mg/kg （89% and 93%, respectively）, similarly to 5-hydroxytrypta- mine4 （5-H%） agonist tegaserod （81%） when compared to vehicle-treated control （63%）. Co-administered man- giferin （30 mg/kg） totally reversed the inhibitory effect of opioid agonist morphine, 5-HT3-receptor antagonist ondansetron and transient receptor potential vanilloid-1 receptor agonist capsaicin on GIT, but only to a partial extent with the GIT-delay induced by ~2-adrenoceptor agonist clonidine, and calcium antagonist verapamil. However, co-administered atropine completely blocked the stimulant effect of mangiferin on GIT, suggesting the involvement of muscarinic acetylcholine receptor activation. Although mangiferin significantly enhanced the 6 h fecal output at higher doses （245.5±10.43 mg vs 161.9±10.82 mg and 227.1±20.11 mg vs 161.9±10.82 mg of vehicle-treated control, at 30 and 100 mg/ kg, P 〈 0.05, respectively）, the effect of tegaserod was more potent （297.4±7.42 mg vs 161.9±1

AIM: To study the benef icial effects of triterpene α,β-amyrin and the underlying mechanisms in an experimental pancreatitis model. METHODS: Acute pancreatitis was induced in five groups of rats (n = 8) by L-arginine (2 × 2.5 g/kg, intraperitoneal, 1 h apart) and 1 h later, they received a single oral dose of α,β-amyrin (10, 30 and 100 mg/kg),methylprednisolone (30 mg/kg) and vehicle (3% Tween 80). A saline (0.9% NaCl) treated group served as a normal control. Efficacy was assessed at 24 h by determination of serum levels of amylase, lipase and proinflammatory cytokines [tumor necrosis factor (TNF)-α and interleukin (IL)-6], pancreatic myeloperoxidase (MPO) activity, lipid peroxidation [thiobarbituric acid reactive substances (TBARS)], nitrate/nitrite levels, and the wet weight/body weight ratio. Tissue histology and the immunoreactivity for TNF-α and inducible nitric oxide synthetase (iNOS) were performed. RESULTS: α,β-amyrin and methylprednisolone treatments significantly (P < 0.05) attenuated the L-arginine-induced increases in pancreatic wet weight/body weight ratio, and decreased the serum levels of amylase and lipase, and TNF-α and IL-6, as compared to the vehicle control. Also, pancreatic levels of MPO activity, TBARS, and nitrate/nitrite were signifi cantly lower. Histological f indings and TNF-α and iNOS immunostaining further confirmed the amelioration of pancreatic injury by α,β-amyrin. CONCLUSION: α,β-amyrin has the potential to combat acute pancreatitis by acting as an anti-in? ammatory and antioxidant agent.

在药物研发领域,野生动物的毒液正被广泛研究,许多基于毒液组分的研究以生物技术应用和专利申请形式被报道。巴西拥有丰富的生物多样性,公布的科研论文和专利申请数量显示了该资源是多么重要。本文报道了一份研究最透彻的巴西有毒动物物种清单及从2000年到2013年的专利申请情况,包括源自巴西有毒物种的毒液成份、毒素及其衍生物。分析了涉及物种的数据、产品类型与发明者的国籍。55个专利申请涉及8个种属,响尾蛇、南美巨蝮蛇、矛头蝮蛇、斜蛛占其中78%。其余22%的专利来自巴西游走蛛、巴西金幽灵蝎、巴西捕鸟蛛、叶水蛙的毒液研究。大多数的发明(42%)包括抗癌、免疫调节剂或抗菌的药物,13%的发明为抗毒血清和疫苗,11%为降压成分,9%为镇痛及抗炎成分,其它25%为一些技术和试剂盒。巴西发明家占专利申请比重的49%,而其它国家如美国、德国、俄罗斯和法国同样发表了巴西动物毒液、毒素或衍生物的专利。虽然巴西拥有着大多数有毒物种的专利,但这些专利主要属于其学校和研究机构,药物工业在这方面依然薄弱。迄今为止,在世界范围内,已将巴西的有毒物种运用于药物研发,但大多数的物种可否作为研发的重要工具,仍然需要作进一步的勘探。

Introduction: In low- and middle-income countries, including Brazil, conditions that favor mortality in the PICU remain significant. Compared to developed countries, there is a shortage of skilled human resources, lower availability of technological resources, greater difficulty of access and a higher incidence of infections, including both those acquired prior to admission and those resulting from treatment and hospitalization (i.e., healthcare-associated infections (HAIs)). HAIs in the PICU include ventilator-associated pneumonia and catheter-related bloodstream infections. Actions for the prevention of HAIs can minimize the occurrence of negative outcomes. Materials and Methods: This is an epidemiological study comparing admissions at the PICU of a high-complexity hospital in South Brazil over two three-year periods: 2012-2014 (before the measures were adopted) and 2015-2017 (after the measures). The care measures were adopted mainly at the beginning of 2015 and consisted of expansion of physical therapy care, adoption of care protocols, acquisition of new materials and equipment (transparent dressings for central catheters, high-tech mechanical ventilators and multiparametric monitors) and multidisciplinary team training. The frequency of the outcomes mortality, length of PICU stay, diagnosis of catheter-related bloodstream infection, need for and duration of ventilatory support and diagnosis of ventilator-associated pneumonia were compared between the two trienniums using logistic regression with adjustment for age in months and need of vasoactive drugs. Results: A total of 1140 admissions were analyzed (470 in the first triennium and 670 in the second), representing an increase in the admission rate of 42.6% after the adoption of the measures. After adjustments, significant reductions in the frequency of mortality (adjusted OR [adjOR] = 0.54;CI 95%: 0.34 - 0.84), length of PICU stay > 7 days (adjOR = 0.75;CI 95%: 0.57 - 0.97) and duration of ventilatory suppor
