Centro de Pesquisas Gonçalo Moniz. Salvador, Bahia, Brasil / O objetivo deste trabalho é desenvolver um ensaio de adesão, baseado no ensaio de Stamper- Woodruff, para o estudo das interações entre macrófagos e matriz conjuntiva. Foram induzidos bolsões inflamatórios em camundongos da linhagem BALB/c para obtenção de secções de pele inflamada, e células macrofágicas da linhagem J774G.8 foram utilizadas na padronização do ensaio. Secções de 7 i^m de espessura foram colocadas em lâminas de vidro, fixadas com acetona e bloqueadas com BSA. Foi estabelecida a concentração de 10® células/100 fil como a mais apropriada para a realização do ensaio, através de diluições seriadas. Células J774G.8 sem tratamento prévio ou tratadas com: ácido tetraacético diamino etileno, Mn++, lipopolissacarídeo, forbol miristato acetato, zimosan, os peptídios CS-1 e RGD, os anticorpos anti-CD49d ou contra a cadeia (32 de integrinas, foram adicionadas ás secções e incubadas por 30 minutos á temperatura ambiente. Como resultado, as células macrofágicas aderem preferencialmente ás áreas de inflamação. A adesão das células é dependente de cátions divalentes e pode ser modulada por substâncias que promovam a ativação celular. Além disso, a adesão mediada por integrinas pode ser inibida por peptídios RGD e CS-1 ou com anticorpos contra integrinas da família (31 e (32. A adesão das células macrofágicas é inibida mais intensivamente pela infecção com Leishmania mas não com a infecção por Mycobacterium ou por fagocitose de partículas de látex. Desta forma, o ensaio desenvolvido foi capaz de demonstrar a especificidade da adesão de células macrofágicas pela matriz conjuntiva bem como de sugerir a existência de mecanismos específicos de regulação das interações entre macrófagos e a matriz conjuntiva durante a infecção por Leishmania. / The aim of this work was to develop an adhesion assay, based on the Stamper-Woodruff’s assay to study the interactions between macrophages and the connective matrix. Inflammatory pouches were produced in BALB/c mice to obtain inflammed skin sections, and J774G.8 macrophage cell line was applied to standardize the assay. Sections of 7|im thick were placed onto glass slides, fixed with acetone and blocked with bovine serum albumin. The cell concentration of 10®/100 |xl was proved to be most appropriate for the assay, through serial dilutions. J774G.8 cells, with or without ethylene diamine tetraacetic acid, Mn'"'", Lipopolysaccharide, phorbol myristate acetate, zymosan, CS- 1, RGD peptide, antibodies anti-CD49d or against (32 chain integrin treatment, were added onto the sections and incubated for 30 minutes at room temperature. Macrophage cells adhered preferentially to inflammed areas. The adhesion of cells was dependent on divalent ions and could be modulated by substances that promote cell activation. Moreover, the adhesion mediated by integrin can be inhibited either by RGD or CS-1 peptides or by antibodies against integrins of the |31 or |32 sub-family. Adhesion of macrophage cells was intensively inhibited by infection with Leishmania and was not affected by infection with Mycobacterium or by endocytosis of latex beads. Thus, the developed assay was able to show the specific adhesion of macrophages to connective matrix, as well to illustrate a specific downregulation of macrophage adhesion to inflammed skin in Leishmania infection.

Foram confeccionadas 2 feridas no dorso de 30 ratos com um punch de 3mm de diâmetro. Os animais foram divididos em três grupos de 10: no Grupo I as feridas foram irradiadas com o laser de CO2, l 10,6 mm, (1,5 W -50 Hz); no Grupo II as feridas foram irradiadas com o laser de Er:YAG, l 2,94 mm (300 mJ -10 Hz), tempo de irradiação de 23 segundos em ambos os grupos; e no grupo III as feridas não foram submetidas à irradiação. Após o ato operatório, todas as feridas foram forradas com MTA. Os animais foram mortos em períodos de 1 dia e 7 dias e as peças removidas, processadas, coradas com hematoxilina / eosina e analisadas no microscópio óptico. Aos 7 dias, no grupo do Er:YAG foi observada a presença de tecido de granulação, porém no grupo do CO2 ainda houve uma severa reação inflamatória com áreas de necrose tecidual. No grupo controle não houve inflamação aos 7 dias na maioria dos casos. Conclusão: os resultados obtidos no presente estudo nos permitem afirmar que o tecido conjuntivo reagiu de forma mais favorável à irradiação laser de Er:YAG do que à irradiação do laser de CO2, independentemente do tempo pós-operatório. / The present study assesed the connective tissue reaction after irradiation with CO2 and Er:YAG lasers in in the back of rats. Two wounds were practiced in the back of tirthy rats with a 3mm diameter punch. The animals were divided into three groups of ten specimens each: In Group I the wounds were irradiated with a CO2 laser, l 10,6mm, (1,5 W -50 Hz) ; In Group II the wounds were irradiated with a Er:YAG laser, l 2,94m, (300 mJ -10 Hz), in both groups the irradiation time was of 23 seconds; Group III received no irradiation. After the intervention, all wounds were covered with MTA. The specimens were killed after intervals of 1 to 7 days and samples collected, proccesed and stained with hematoxilin/eosin, and analized under the ligth microscope. At seven days period the Er:YAG group exhibited granulation tissue proliferation, while in the CO2 group a severe inflamatory reaction persisted with areas of necrosis. In the control group there was no inflamation in most of the cases after 7 days period. Conclusions: The results yielded by the present study lead us to assure that the reaction of the connective tissue was most favorable to irradiation with Er:YAG laser than with CO2 laser, regardless the time elapsed after the intervention.
