ABSTRACT

ABSTRACT INTRODUCTION: Chronic lung disease (CLD), clinically known as bronchopulmonary dysplasia (BPD), is a major cause of morbidity in premature newborn and were submitted to oxygen therapy. OBJECTIVE: Immunohistochemical identification of inflammatory molecules in the lung tissue of premature neonates that died with CLD. METHODS: Immunohistochemical analysis of 51 samples of premature newborn lungs – grouped in: without CLD,"classic" CLD and"new" CLD. RESULTS: Neutrophil influx and the number of CD4+ and CD45RO+ cells were higher in the"classic" CLD group (p < 0.001). CONCLUSION: Our findings suggest that the inflammatory response is mediated by neutrophils and CD45RO+ and CD4+ T lymphocytes in the"classic" CLD.


RESUMO INTRODUÇÃO: A doença pulmonar crônica (DPC), conhecida clinicamente como displasia broncopulmonar, é uma das maiores causas de morbidade em neonatos que nasceram prematuros e foram submetidos à oxigenioterapia. OBJETIVO: Identificar moléculas inflamatórias em tecido pulmonar de recém-nascidos prematuros que morreram com DPC por meio do método de imuno-histoquímica. MÉTODOS: Análise imuno-histoquímica de 51 amostras de pulmões de recém-nascidos prematuros – formando os grupos: sem DPC, DPC"nova" e DPC"clássica". RESULTADOS: O influxo de neutrófilos e o número de células CD4+ e CD45RO+ foram maiores no grupo DPC"clássica" (p < 0,001). CONCLUSÃO: Os resultados sugerem que o processo inflamatório é mediado por neutrófilos e linfócitos CD45RO+ e CD4+ na DPC"clássica".

ABSTRACT

AIM: The aim of the present study was to investigate the validity of the Lactate Minimum Test (LMT) for the determination of peak VO(2) on a cycle ergometer and to determine the submaximal oxygen uptake (VO(2)) and pulmonary ventilation (VE) responses in an incremental exercise test when it is preceded by high intensity exercise (i.e., during a LMT). METHODS: Ten trained male athletes (triathletes and cyclists) performed 2 exercise tests in random order on an electromagnetic cycle ergometer: 1). Control Test (CT): an incremental test with an initial work rate of 100 W, and with 25 W increments at 3-min intervals, until voluntary exhaustion; 2). LMT: an incremental test identical to the CT, except that it was preceded by 2 supramaximal bouts of 30-sec (approximately 120% VO(2)peak) with a 30-sec rest to induce lactic acidosis. This test started 8 min after the induction of acidosis. RESULTS: There was no significant difference in peak VO(2) (65.6+/-7.4 ml x kg(-1) x min(-1); 63.8 +/- 7.5 ml x kg(-1) x min(-1) to CT and LMT, respectively). However, the maximal power output (POmax) reached was significantly higher in CT (300.6+/-15.7 W) than in the LMT (283.2+/-16.0 W). VO(2) and VE were significantly increased at initial power outputs in LMT. CONCLUSION: Although the LMT alters the submaximal physiological responses during the incremental phase (greater initial metabolic cost), this protocol is valid to evaluate peak VO(2), although the POmax reached is also reduced.

ABSTRACT

Los resultados de mayor interés obtenidos sobre las muestras de LCD y suero de 7 casos de hanseniasis (H.D.) (2 borderline: B 3 lepromatosos: L de los cuales el 4 L grave y con déficit inmunitario; 2 tuberculoides: T), son: I.º) Los índices LCR/suero de la albúmina y de las IgG por tests cinético-nefelometría y de las IgG anti PGL-1 por ELISA, en cuanto separan los casos según sus tipos y forma mediante valores típicamente uniformes: los más bajos de albúmina para los L; los más bajos de IgG anti PGL-1 para los B; los medios de IgG para los T, siendo los B y L muy deformantes. II.º) Los index de LINK indican producción intratecal de IgG si superan el V.N. en nuestros casos los de IgG anti PGL-1 han resultado todos superiores y altos, sólo los B menos altos; los IgG todos inferiores; pero, hay que considerar que por la policlonía de la IgG, una parte de ellas podría resultar superior si fuese revelada aisladamente por su antígeno específico. III.º) Una mayor casuística con test de medidas homólogas para los dos de IgG podrá confirmar o no nuestros resultados, y también modificar nuestra de ducción por la cual los epítopes HLA-DR de los queratinocitos uniéndose con las IgG intratecales determinarían la respuesta al test lepromínico, es decir, negativa en los L por la falta de los HLA-DR; positiva la precoz en los B po la unión con la IgG; positiva la tardía y a menudo la precoz en los T por la unión con la IgG anti PGL-1 y las IgG. Otro caso de diagnosis incierta resulta positivo para la H.D. de tipo T, pero atípico o la debido a la asociación de otra enfermedad del S.N.C. como la esclerosis múltiple o la siringomielía.
