Phoradendron piperoides (Kunth) Trel. (Viscaceae) is a parasitic plant widely distributed in regions of the Brazilian northeast. Different species of Phoradendron are used in folk medicine for the treatment of cough, influenza, gastrointestinal and female disorders, and pain. In order to evaluate the actions of this plant, studies were performed on antinociceptive, anti-inflammatory, and antioxidant activities. The methanol extract (ME) and dichloromethane, ethyl acetate, and methanol partitions of P. piperoides leaves were used in the following experiments. Oral treatment with the ME elicited inhibitory activity (p?<?0.01) on the acetic acid effect at 100 (32.08%), 200 (34.46%), and 400?mg/kg (49.50%). P. piperoides ME reduced the formalin effect at the second phase (200 and 400?mg/kg, p?<?0.05); however, the ME did not elicit any inhibitory effect on the hot-plate test. Edema formation induced by carrageenan was reduced (p?<?0.05) with the ME by 28% (200?mg/kg) and 33% (400?mg/kg). ME, dichloromethane, ethyl acetate, and methanol partitions reacted with the DPPH radical and reduced the DPPH radical by 94.5, 37.2, 77.2, and 95.7%, respectively. ME, ethyl acetate, and methanol partitions exhibited low IC50 values. 相似文献

Antiphospholipid antibodies (aPL) and antiphospholipid syndrome (APS) have been described in primary Sj?gren’s syndrome (pSS) with controversial findings regarding aPL prevalence and their association with thrombotic events. We evaluated 100 consecutive pSS patients (American–European criteria) and 89 age–gender–ethnicity-matched healthy controls for IgG/IgM anticardiolipin (aCL), IgG/IgM anti-beta2-glycoprotein-I (aβ2GPI), and lupus anticoagulant (LA) (positivity according to APS Sydney’s criteria). Clinical analysis followed standardized interview and physical examination assessing thrombotic and nonthrombotic APS manifestations and thrombosis risk factors. aPLs were detected in 16?% patients and 5.6?% controls (p?=?0.035). LA was the most common aPL in patients (9?%), followed by aβ2GPI (5?%) and aCL (4?%). Thrombotic events occurred in five patients [stroke in two, myocardial infarction in one and deep-vein thrombosis (DVT) in four], but in none of controls (p?=?0.061). Mean age at time of stroke was 35?years. Three patients with thrombotic events (including the two with stroke) had APS (Sydney’s criteria) and were positive exclusively for LA. Comparison of patients with (n?=?16) and without (n?=?84) aPL revealed similar mean age, female predominance, and ethnicity (p?>?=0.387). Frequencies of livedo reticularis (25 vs. 4.8?%, p?=?0.021), stroke (12.5 vs. 0?%, p?=?0.024), and DVT (18.8 vs. 1.2?%, p?=?0.013) were significantly higher in APL + patients. Conversely, frequencies of hypertension, dyslipidemia, diabetes, obesity, smoking, sedentarism, and hormonal contraception were similar in patients with or without aPL (p?≥?0.253). Our study identified LA as an important marker for APS in pSS, particularly for stroke in young patients, warranting routine evaluation of these antibodies and rigorous intervention in modifiable risk factors. 相似文献

The association of RASopathies [Noonan syndrome (NS) and Noonan-related syndromes] and autoimmune disorders has been reported sporadically. However, a concomitant evaluation of autoimmune diseases and an assessment of multiple autoantibodies in a large population of patients with molecularly confirmed RASopathy have not been performed. The clinical and laboratory features were analyzed in 42 RASopathy patients, the majority of whom had NS and five individuals had Noonan-related disorders. The following autoantibodies were measured: Anti-nuclear antibodies, anti-double stranded DNA, anti-SS-A/Ro, anti-SS-B/La, anti-Sm, anti-RNP, anti-Scl-70, anti-Jo-1, anti-ribosomal P, IgG and IgM anticardiolipin (aCL), thyroid, anti-smooth muscle, anti-endomysial (AE), anti-liver cytosolic protein type 1 (LC1), anti-parietal cell (APC), anti-mitochondrial (AM) antibodies, anti-liver-kidney microsome type 1 antibodies (LKM-1), and lupus anticoagulant. Six patients (14%) fulfilled the clinical criteria for autoimmune diseases [systemic lupus erythematous, polyendocrinopathy (autoimmune thyroiditis and celiac disease), primary antiphospholipid syndrome (PAPS), autoimmune hepatitis, vitiligo, and autoimmune thyroiditis]. Autoimmune antibodies were observed in 52% of the patients. Remarkably, three (7%) of the patients had specific gastrointestinal and liver autoantibodies without clinical findings. Autoimmune diseases and autoantibodies were frequently present in patients with RASopathies. Until a final conclusion of the real incidence of autoimmunity in Rasopathy is drawn, the physicians should be alerted to the possibility of this association and the need for a fast diagnosis, proper referral to a specialist and ultimately, adequate treatment. 相似文献

The aim of this study was to evaluate the efficiency and interactions of attentional systems in children with Attention Deficit Hyperactivity Disorder (ADHD) by considering the effects of reinforcement and auditory warning on each component of attention. Thirty-six drug-na?ve children (18 children with ADHD/18 typically developing children) performed two revised versions of the Attentional Network Test, which assess the efficiency of alerting, orienting, and executive systems. In feedback trials, children received feedback about their accuracy, whereas in the no-feedback trials, feedback was not given. In both conditions, children with ADHD performed more slowly than did typically developing children. They also showed impairments in the ability to disengage attention and in executive functioning, which improved when alertness was increased by administering the auditory warning. The performance of the attentional networks appeared to be modulated by the absence or the presence of reinforcement. We suggest that the observed executive system deficit in children with ADHD could depend on their low level of arousal rather than being an independent disorder. 相似文献

Vascular injuries with acute arterial haemorrhage are rare but the infrequency of these complications may make their diagnosis
and treatment challenging for surgeons unfamiliar with their management. In the past, surgery or coil embolisation has been
used to treat these lesions; we describe the case of a pseudo-aneurysm of the common femoral artery developed during a total
hip arthroplasty, promptly managed with an endovascular stent graft. 相似文献

A classification of bullous dermatoses in childhood is presented, according to the histologic location of the bulla and the heritability of the disease, combined with the most recent laboratory examinations used in dermatologic practice. For a better understanding of the proposed classification, the authors also present a review of this group of diseases, which vary greatly within the group. In this first part of the classification and review, the group of bullous dermatoses with nonhereditary characteristics and intraepidermal cleavage is described. 相似文献
