Effects of anti-asthmatic drugs on airway resistance and plasma level of cyclic AMP were investigated in guinea pigs sensitized and non-sensitized with egg-albumin. Histamine increased airway resistance in the both groups of guinea pigs, and guinea pigs sensitized with egg-albumin were more sensitive to histamine. Anti-asthmatic drugs inhibited dose-dependently the increase of airway resistance...

Understanding reproductive performance in ecologically impoverished vs. more sustained anthropogenic habitats is critical to assess population health status and to develop land use and conservation management strategies. We compared resourcebased maternal effects, reproductive performance, and offspring quality in a model migratory passerine bird, the European starling (Sturnus vulgaris). We as...

Packed human red blood cells, diluted 1:1 with phosphate-buffered saline (PBS) containing 0-21% bovine serum albumin was used as a blood meal source for Anopheles farauti. Egg and larval production linearly increased with bovine serum albumin concentration in PBS. When the saline contained 9-21% bovine serum albumin, egg production was equivalent to that obtained when mosquitoes were fed direct...
