Demonstration of antibody and cellular immune response to brain extract in West and Lennox-Gastaut syndromes
Investigamos a resposta imunolĂłgica celular e humoral frente a extrato salino de tecido cerebral em 9 pacientes com sĂndrome de Lennox-Gastaut, 15 pacientes com sĂndrome de West e 20 crianças normais. A tĂ©cnica de imunodifusĂŁo dupla em gel de agar (Ouchterlony) evidenciou em todos os pacientes, altos nĂveis de um anticorpo precipitante contra o extrato salino de tecido cerebral. O teste de inibição de migração de leucĂłcitos com o mesmo antĂgeno mostrou-se positivo na maioria dos pacientes. O possĂvel papel destas respostas autoimmunes na patogenia das sindromes de West e Lennox-Gastaut Ă© discutido.We investigated humoral and cellular immune response to brain tissues in 15 patients with West syndrome, in 9 patients with Lennox-Gastaut syndrome and in 20 healthy children. High levels of a precipitating antibody to a saline extract of brain tissue were detected in all patients; leucocyte migration inhibition test with the same antigen was found to be positive in most of them. The role of this autoimmune response in the pathogenesis of West and Lennox-Gastaut syndromes remains to the elucidated
Immunological disturbance in West and Lennox-Gastaut syndromes
Cell-mediated and humoral immunity were investigated in 18 patients with West syndrome, 12 with Lennox-Gastaut syndrome and 19 healthy controls. The study included determination of Ă and Ă peripheral blood lymphocytes, serum levels of IgG, IgA and IgM, skin sensibilization with DNCB, intracutaneous PHA, leucocyte migration inhibition test and lymphocyte blastic transformation in the presence of PHA. Cell-mediated deficiency was detected in 28 children whereas low levels of immunoglobulins were observed only in 6 children. Immunological disturbances were more prominent in children with West syndrome
ContribuiçÔes da Sociologia na AmĂ©rica Latina Ă imaginação sociolĂłgica: anĂĄlise, crĂtica e compromisso social Sociology's contribution in Latin America to sociological imagination: analysis, critique, and social commitment
O artigo aborda o papel desempenhado pela Sociologia na anĂĄlise dos processos de transformação das sociedades latino-americanas, no acompanhamento do processo de construção do Estado e da Nação, na problematização das questĂ”es sociais na AmĂ©rica Latina. SĂŁo analisados seis perĂodos na Sociologia na AmĂ©rica Latina e no Caribe: I) a herança intelectual da Sociologia ; II) a sociologia da cĂĄtedra; III) O perĂodo da "Sociologia CientĂfica" e a configuração da "Sociologia CrĂtica"; IV) a crise institucional, a consolidação da "Sociologia CrĂtica" e a diversificação da sociologia; V) a sociologia do autoritarismo, da democracia e da exclusĂŁo; VI) a consolidação institucional e a mundialização da sociologia da AmĂ©rica Latina (desde o ano de 2000), podendo-se afirmar que os traços distintivos do saber sociolĂłgico no continente foram: o internacionalismo, o hibridismo, a abordagem crĂtica dos processos e conflitos das sociedades latino-americanas e o compromisso social do sociĂłlogo.<br>The article focuses on the role played by Sociology in the analysis of processes of change in Latin American societies, in the process of construction of Nation and State, in the debate of social issues in Latin America and the Caribbean. Six periods in Sociology in Latin America and the Caribbean are examined: I) sociology's intellectual legacy; II) sociology as a cathedra; III) the period of "Scientific Sociology"; IV) the institutional crisis, the consolidation of "Critical Sociology", and the diversifying of sociology; V) sociology of authoritarianism, democracy and exclusion; VI) institutional consolidation and globalization of Latin American sociology (since 2000). It may be said that the distinctive features of sociological knowledge in the continent were: internationalism, hybridism, the critical approach to processes and conflicts of Latin American societies, and the sociologist social commitment
