| This study was carried out to compare the physiochemical quality of honeys from beekeepers in northern Zona da Mata, MG, and honeys from warehouses registered at the Serviço de Inspeção Federal (SIF) in the State of Minas Gerais. Physiochemical analysis involving 39 samples were done, with three samples from each of the 13 beekeepers and 18 samples from warehouses registered at SIF-MG. Differences in quality from the two origins occurred in: free acidity, ashes, hydroxymethylfurfural, apparent sucrose and insoluble solids, where honeys from warehouses were of better quality. In addition, for free acidity and insoluble solids, two samples from northern Zona da Mata showed values above the established by the Instrução Normativa n°11 relative to the year... |

| Histamine release induced by plant lectins was studied with emphasis on the carbohydrate specificity, external calcium requirement, metal binding sites, and mast cell heterogeneity and on the importance of antibodies bound to the mast cell membrane to the lectin effect. Peritoneal mast cells were obtained by direct lavage of the rat peritoneal cavity and guinea pig intestine and hamster cheek pouch mast cells were obtained by dispersion with collagenase type IA. Histamine release was induced with concanavalin A (Con A), lectins from Canavalia brasiliensis, mannose-specific Cymbosema roseum, Maackia amurensis, Parkia platycephala, Triticum vulgaris (WGA), and demetallized Con A and C. brasiliensis, using 1-300 µg/ml lectin concentrations applied to Wistar... |
