A screen test for rubella haemagglutination inhibition antibodies.

The findings agree closely with those of Hobbs and Aw (1968). The isoamylase patterns of normal plasma and urine are similar, though the activity in urine is greater. Three bands are usually found in normal urine, the slower, and usually more distinct, band being the pancreatic component, and the faster those derived from salivary gland. The activities of these isoenzymes in plasma appear to be equal. In cases of pancreatitis, the slower band becomes much more distinct, and often further activity can be detected between this and the salivary bands. This is a similar pattern to that found in pancreatic extract. Saliva shows three bands, all faster than those of pancreatic origin, and a similar pattern is seen in the plasma in parotitis, with an increase in the fastest band. These appearances can all be clearly seen in the
