RESUMO
A asma é doença crônica frequente na gestação, cujo descontrole encontra-se associado a desfechos maternos e perinatais desfavoráveis. O manejo da doença apresenta desafios, tais como a resistência das pacientes em utilizar medicações durante a gravidez, além de queixas frequentes de dispneia associada ao estado gravídico, não relacionada à asma. O objetivo do presente trabalho foi revisar os conhecimentos atuais sobre asma na gravidez. As fontes de dados foram revisões e artigos originais publicados nos últimos 12 anos e indexados nas bases de dados PubMed, SciELO e Lilacs. As conclusões deste artigo de revisão indicam que o controle adequado da asma juntamente com a vigilância obstétrica cuidadosa devem ser integrados e constituir objetivo global do tratamento de gestantes asmáticas. O tratamento medicamentoso permite o uso de algumas medicações utilizadas em pacientes não gestantes.
Asthma is a common chronic disease during pregnancy, and inappropriate control of this conditionis associated with unfavorable maternal and perinatal outcomes. Management of asthma duringpregnancy presents challenges, including the patients resistance to use medications duringpregnancy and frequent complaints of dyspnea associated with pregnancy but not related toasthma. The objective of the present study was to review the current knowledge about asthmain pregnancy. Data sources included reviews and original articles published in the past 12 yearsand indexed in PubMed, SciELO, and Lilacs databases. Our findings indicate that adequate controlof asthma and careful obstetric follow-up should be integrated and constitute a global goal intreating pregnant women with asthma. Pharmacologic treatment allows for the use of somemedications that are used in non-pregnant patients.

A lectin was purified from the seaweed Gracilaria cornea by hydrophobic interaction chromatography on phenyl-Sepharose CL-4B followed by affinity chromatography on immobilized mucin. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis of G. cornea lectin (GCL) revealed a single protein band of approximately 60 kDa, whereas by gel filtration on Sephadex G-100 its native molecular mass was 66 kDa. GCL exhibited a single isoeletric point of 4.3 and a 52.5% content of neutral sugars. Furthermore, the EDTA-treated lectin did not show any significant decrease in its ability to agglutinate trypsin-treated chicken erythrocytes. These data suggest that GCL is an acidic, monomeric glycoprotein that probably does not require divalent metal ions for its hemagglutinating activity. GCL hemagglutinating activity was not inhibited by any of the mono-, di-, and trisaccharides tested but was by the complex glycoproteins fetuin and porcine stomach mucin. Exposure of engorged females of the cattle tick (Boophilus microplus) to 0.1 mg mL(-1) GCL significantly (P < 0.05) reduced the female weight after the oviposition period, the egg mass weight, the hatching period, and the mean larvae survival time.
