the most frequent adverse effects of indomethacin like other nsaids are gastro–intestinal and central nervous system disturbances. extended release or enteric release formulations minimize these symptoms. the objective of this study was to develop an extended release pellet formulation of indomethacin by the centrifugation (rotary fluid bed granulation) or powder layering method. layered, nonpa...

1. The effects of defaunation of the rumen of cattle on low-protein diets was studied using animals given free access to a basal diet of liquid molasses and 1500 g oaten straw/head per d. These diets induced moderate numbers of protozoa in the rumen. 2. Nonyl phenol ethoxylate (trade name teric GN9) was used for defaunation; 100 g teric GN9 was found to be sufficient to eliminate protozoa from ...

Three experiments were conducted to evaluate the in ̄uence of an algae derived feed additive, Spirulina platensis (SP), on weanling pig performance. In all experiments, pigs were blocked by weight and allotted to one of four (experiments 1 and 3) or six (Experiment 2) dietary treatments. Standard diets and feeding regimens were implemented in all three experiments and SP replaced soybean meal on...

We report on the modulatory effects of chronic subcutaneous or oral estrogen and LY117018, a selective estrogen receptor modulator, on the release of nitric oxide in rings of rat aorta studied under isometric conditions. Dilator responses to acetylcholine (ACh; 10[8] to 10[-5] M) were obtained in phenylephrine (PE; 2 microM)-contracted aorta, and constrictor dose-response curves to PE (10[-8] t...
