Diversidade da fauna edáfica em solos submetidos a diferentes sistemas de manejo no semi-árido nordestino

Abstract: The study aimed to evaluate the effect of the traditional burning and the enleirament of residues on the organism edafic abundance and diversity under caatinga. For this research four areas had been selected: a) caatinga deforested, burnings and planted with corn and beans in the first year; b) caatinga deforested, burnings and planted with corn and beans in the second year consecutive; c)caatinga deforested and the organic residues located in leiras and planted with corn and beans between the leiras; d) Bush with about 50 years. Traps of "pitfall" type were installed for soil edafic fauna collection. The burnings accomplished in the treatments cultivated with corn and beans, resulted in reduction in the abundance and diversity of soil fauna, while that the enleirament of residues showed to be the one practical conservative one for the fauna. The analysis of main components showed to strong association group Diptera with the system management with leiras and of the groups Larva of Coleoptera, Scorpionidae and Collembola with the bush. In turn, in the systems that had suffered burnings only the Orthoptera group if detached.

Caracterização sociodemográfica e clínica de pessoas com estomia em Teresina

Abstract: O estudo teve por objetivo caracterizar o perfil sociodemografico e clinico de pessoas cadastradas no Programa de Estomizados de Teresina (PI). Pesquisa exploratorio-descritiva, transversal, com abordagem quantitativa, cujos dados foram coletados no periodo de junho a julho de 2013, sendo utilizado o programa Statistical Package for the Social Sciences (SPSS), versao 19.0, para analise estatistica. A pesquisa foi aprovada pelo Comite de Etica e Pesquisa (CEP) da Universidade Federal do Piaui (UFPI), sob CAAE no 10487813.3.0000.5214. A amostra foi constituida por 107 estomizados, que atenderam aos criterios de inclusao. Houve predominio de estomizados do sexo masculino (55,1%); media de idade de 59,2 anos; casados (48,6%); com filhos (86,9%); catolicos (81,3%); renda familiar entre 1 e 3 salarios minimos (60,7%); ensino fundamental incompleto (32,7%); aposentados (57,0%). As neoplasias constituiram a principal causa da estomia (71,0%), seguidas de doencas inflamatorias intestinais (20,6%); a maioria era colostomizada (74,8%), permanente (48,6%), ha menos de um ano (39,3%); apresentava efluente de consistencia pastosa (74,8%); utilizava bolsa coletora de peca unica (94,4%), sendo 100% drenavel, fornecida pelo Sistema Unico de Saude (SUS) (73,8%). Dentre as 41 (38,3%) complicacoes apresentadas pelos participantes, 30 (73,1%) referiam-se a pele periestoma caracterizado, 29, ao eritema (96,7%), e 11 (26,82 %), ao estoma, sendo verificados prolapso, 10 (90,0%), e sangramento, 1 (3,3%). Os resultados obtidos mostraram aproximacoes e semelhancas em comparacao com as literaturas nacional e internacional. Conclui-se que o conhecimento do perfil dessa clientela possibilitara a adequacao do planejamento da assistencia especializada e da provisao de equipamentos coletores e adjuvantes no contexto do Estado do Piaui.

Mechanisms of the antinociceptive action of (-) epicatechin obtained from the hydroalcoholic fraction of Combretum leprosum Mart & Eic in rodents.

Abstract: Background: The mechanisms of the antinociceptive activity of (�) epicatechin (EPI), a compound isolated from the hydroalcoholic fraction of Combreum leprosum Mart & Eicher. Methods: were assessed in the model of chemical nociception induced by glutamate (20 μmol/paw). To evaluate the mechanisms involved, the animals , male Swiss mice (25-30 g), received EPI (50 mg/kg p.o.) after pretreatment with naloxone (2 mg/kg s.c. opioid antagonist), glibenclamide (2 mg/kg s.c. antagonist K+channels sensitive to ATP), ketanserin (0.3 mg/kg s.c. antagonist of receptor 5-HT2A), yoimbine (0.15 mg/kg s.c. α2 adrenergic receptor antagonist), pindolol (1 mg/kg s.c. 5-HT1a/1b receptor antagonist), atropine (0.1 mg/kg s.c. muscarinic antagonist) and caffeine (3 mg/kg s.c. adenosine receptor antagonist), ondansetron (0.5 mg/kg s.c. for 5-HT3 receptor) and L-arginine (600 mg/kg i.p.). Results: The antinociceptive effect of EPI was reversed by pretreatment with naloxone and glibenclamide, ketanserin, yoimbine, atropine and pindolol, which demonstrates the involvement of opioid receptors and potassium channels sensitive to ATP, the serotoninergic (receptor 5HT1A and 5HT2A), adrenergic (receptor alpha 2) and cholinergic (muscarinic receptor) systems in the activities that were observed. The effects of EPI, however, were not reversed by pretreatment with caffeine, L-arginine or ondansetron, which shows that there is no involvement of 5HT3 receptors or the purinergic and nitrergic systems in the antinociceptive effect of EPI. In the Open Field and Rotarod test, EPI had no significant effect, which shows that there was no central nervous system depressant or muscle relaxant effect on the results. Conclusions: This study demonstrates that the antinociceptive activity of EPI in the glutamate model involves the participation of the opioid system, serotonin, adrenergic and cholinergic.
