## Abstract The earthworm __Lumbricus terrestris__ is ammonotelic while feeding but becomes ureotelic with fasting. The metabolic sources of ammonia nitrogen in feeding worms have been examined. Two deaminating enzymes, Lβserine dehydratase and 5β²βAMP deaminase, have been observed to be present in

## Abstract Cultured chick embryo cardiac myocytes submitted to a 180mOsm/kg hyposmotic solution swell present a regulatory volume decrease (RVD). This RVD is mediated by a Ca^2+^influx followed by a 40% loss of total taurine content accompanied by the loss of lesser amounts of other osmolytes. Kid
## Abstract The mechanisms of cell volume regulation in molluscs have been examined in detail in only a few species. While generalizations must be made with some caution until additional species have been tested, the following mechanism has emerged. When stressed with a decreased external salinity
