Efeito gastroprotetor e perfil toxicologico dos polissacarídeos sulfatados da a...
Carneiro, José GerardoOur objective was to evaluate the cases of PS spiders in the green seaweed C. mexicana (PS-Cm) in models of gastric damage induced by ethanol in mice and its toxic effects. By studying the gastroprotective action, groups of male Swiss mice were treated with PS-Cm (2, 20 or 200 mg / kg, v.o.) and subjected to gastric injury induced by absolute ethanol. Also, the case, also, the involvement of the final pathways ...
Gastroprotective effects of sulphated polysaccharides from the Alga Caulerpa me...
Carneiro, José Gerardo; Holanda, Ticiana de Brito Lima; Quinderé, Ana Luíza Gomes; Frota, Annyta Fernandes; Soares, Vitória Virgínia MagalhãesThe development of the gastric lesion is complex and the result of the imbalance between aggressive and protective factors, involving the generation of free radicals and disturbance in nitric oxide (NO) production. Sulphated polysaccharides (SP), from marine algae, are widely used in biotechnological and pharmaceutical areas. In this study, we evaluated the effects of SP from the green marine alga Caulerpa mexi...
Efeitos dos polissacarídeos sulfatados da alga marinha verde Caulerpa mexicana ...
Carneiro, José GerardoSulfated polysaccharides from seaweed are heterogeneous polymers representing biomolecules of commercial interest, especially in food and pharmaceutical industries. The aim this study was to evaluate the effects of total sulfated polysaccharides (TSP) of the green seaweed Caulerpa mexicana in classical models of nociception and acute inflammation in animals. Swiss male mice (18-25 g) and male Wistar rats (120-2...
Analysis of two precipitation methods on the yield, structural features and act...
Souza, Ricardo Basto; Queiroz, Ismael Nilo Lino de; Silva Neto, Antônio Alves da; Carneiro, José Gerardo; Rodrigues, José Ariévilo GurgelThe global demand for natural products from seaweeds has increased worldwide; however, no description of the use of isoamly alcohol (IAA) for obtaining of sulfated polysaccharides (SPs) has been reported. We investigated the efficiency of two precipitation methods (M) in obtaining SPs from the red seaweed Gracilaria cornea. SPs enzymatically isolated were concentrated with cetylpyridinium chloride (M I) or IAA ...
Analysis of some chemical nutrients in four Brazilian tropical seaweeds
Carneiro, José Gerardo; Rodrigues, José Ariévilo Gurgel; Teles, Felipe Barros; Cavalcante, Antônio Belfort Dantas; Benevides, Norma Maria BarrosSeaweeds have various chemical components with beneficial effects for human use; however, their nutritional values in Brazilian species are not well known. This study aimed to evaluate the content of water, ash, protein, carbohydrate, and lipid in four seaweeds (Hypnea musciformis, Solieria filiformis, Caulerpa cupressoides and C. mexicana). Algal constituents were determined by difference, gravimetric or color...
