    Notes: Summary Protamine is shown to be a powerful disrupter of calcium homeostasis, acutely inducing a severe hypocalcemia in both rabbits and rats. The magnitude of its effect correlates with bone turnover. Protamine does not significantly alter the renal excretion of calcium, and is effective whether or not there is calcium present in the gut. Protamine causes a significant fall in the specific activity of45Ca in the blood in animals whose bone has been prelabeled with45Ca. These data suggest that protamine induces hypocalcemia by blocking calcium efflux from bone. Further work seems indicated to define the biochemical mechanism of this action.

    Notes: Abstract A 31-year-old female with severe Crohn's disease for 15 years who had been treated with corticosteroids and 6-mercaptopurine, was treated with thalidomide initially for erythema nodosum. While on thalidomide all symptoms of Crohn's disease disappeared and she was able to discontinue all other drugs. At this writing she has been on thalidomide as sole therapy for over 4 years with the exception of a 5-week hiatus, during which time her symptoms recurred, but again disappeared after resumption of thalidomide therapy. This case suggests that thalidomide may be a useful therapy for Crohn's disease and provides impetus for a clinical trial of thalidomide for Crohn's disease.
