Vertical and horizontal interactions between membrane constituents account for integrity, strength and deformability of the erythrocyte. Disruption of vertical interactions caused by membrane protein deficiencies in hereditary spherocytosis (HS), favor membrane vesiculation with development of spherocytic cells. Our aim was to evaluate the hematological and(More)
AIM OF THE STUDY To identify the compounds responsible for the antinociceptive and anti-inflammatory effects previously described for Sedum dendroideum, through bioassay-guided fractionation procedures. MATERIALS AND METHODS Antinociceptive activity was evaluated through mouse acetic acid-induced writhing model. The anti-inflammatory activity was assessed(More)
UNLABELLED The authors report a case of hydrops fetalis due to severe pyruvate kinase deficiency, the most unusual clinical manifestation of this disease. CONCLUSION Pyruvate kinase deficiency, as other erythrocyte enzymopathies, must be considered in the differential diagnosis of non-immune hydrops fetalis. This has important implications for clinical(More)
The croton oil-induced mouse ear oedema test, acetic acid-induced abdominal writhing, and carrageenan-induced peritonitis were used to study the anti-inflammatory effects of the crude ethanol extract and its alkaloid fraction from Solanum lycocarpum fruits. The alkaloid fraction induced a dose-dependent reduction in ear oedema formation and leukocyte(More)
Eosinophil migration in vivo is markedly attenuated in rats treated chronically with the NO synthase (NOS) inhibitor Nomega-nitro-L-arginine methyl ester (L-NAME). In this study, we investigated the existence of a NOS system in eosinophils. Our results demonstrated that rat peritoneal eosinophils strongly express both type II (30.2 +/- 11.6% of counted(More)
To determine whether Gilbert's syndrome increases the risk of gallstone formation in children with chronic hemolytic disease, we studied 44 children with this diagnosis. Gallstones were detected by abdominal ultrasonography. This took place annually in scheduled examinations or in the context of acute abdominal pain. In all patients, the mean values of(More)
We report the results of 10 years of prophylactic fresh-frozen plasma (FFP) infusion therapy in a 14-year-old girl with chronic relapsing thrombotic thrombocytopenic purpura (TTP), in whom a severe congenital von Willebrand factor (VWF)-cleaving protease deficiency has been documented. Severe haemolytic crises triggered by infections were prevented and her(More)
The focuses of palliative care are to provide symptom relief and improve quality of life through an interdisciplinary approach. Previous studies conducted to evaluate the effectiveness of palliative care in reducing symptom distress among outpatients confirmed the importance of the palliative care approach. To our knowledge, there is no published(More)
Spiranthera odoratissima A. St. Hil. (manacá) is used in folk medicine to treat renal and hepatic diseases, stomachache, headaches and rheumatism. A central nervous system (CNS) depressant effect of the hexane fraction from the ethanolic extract of this plant has been described. β-caryophyllene, the main component of this essential oil, is a sesquiterpene(More)
Our study sought to evaluate the anxiolytic and antidepressant activities of oleanolic acid as well as the neural mechanisms involved. Animal models such as barbiturate sleep-induction, light-dark box, elevated plus maze, forced swimming test, tail suspension test and open field test were conducted. Male Albino Swiss mice were treated orally with vehicle 10(More)
