Certain patients are seen, however, who despite such careful determinations cannot be kept in stable equilibrium. The blood sugar of these patients fluctuates widely throughout the day, or they have glycosuria and hyperglycemia sometime during the late hours of the night or early morning. The slow-acting insulins were devised particularly for the purpose of smoothing out these diurnal variations, and both protamine zinc insulin and crystalline insulin have been of great help.
