1. With Conn.-5 strain of Coxsackie virus, pancreatic disease can be regularly produced in adult mice. 2. The lesions consist of widespread necrosis, followed by repair; there occurs more or less complete loss of glandular acini, with fatty or fibrous replacement. The islands of Langerhans and pancreatic ducts persist. 3. Injection of virus suspensions by the intraperitoneal, subcutaneous, intramuscular, or intracerebral route is followed by selective necrosis of the pancreas. 4. The liver, in the earlier stages of the disease, is the seat of fat infiltration. There may be necrosis of individual hepatic cells, but the diffuse hepatitis described in suckling mice does not occur. In the later stages of the disease, the liver is not significantly altered. 5. Localized areas of fat necrosis, scattered through intra-abdominal adipose tissue, are usually present in the acute phase of the disease. These undergo fibrosis without calcification. 6. No lesions have been found in the skeletal muscle, even at the site of intramuscular injection. Central nervous system, heart, lungs, and peripheral fat lobules show no lesions comparable to those described in suckling mice. 7. Multiplication of virus takes place in the pancreas. Serial passage in adult mice, by injection of pancreas suspensions prepared from organs removed on the 4th day after infection, is readily accomplished. Five consecutive passages in adult mice have thus far been carried out. Pancreas suspension from 4th passage material produced typical disease in suckling mice when diluted 10(-6). No virus could be demonstrated in pancreas obtained 25 days after inoculation. 8. Complete protection against the pancreatic disease is obtained when the virus is neutralized, before injection, with Conn.-5 antiserum. Normal mouse serum and antiserum against the Ohio-R strain of Coxsackie virus have no protective effect. 9. Mice surviving the initial necrotizing effect of the virus, develop chronic pancreatic insufficiency. This is manifested by extreme weight loss-in some cases, 40 per cent or more of the body weight-and by hypoproteinemia, sometimes leading to anasarca. 10. The substitution of fox-chow which has been predigested with hog pancreas brings about a restoration of weight. 11. The possibility is considered that similar lesions of the pancreas in human beings may be due to virus infection.

When blood plasma proteins are depleted by bleeding, with return of washed red cells (plasmapheresis) it is possible to bring the dog to a steady state of low plasma protein and uniform plasma protein production on a basal diet. Such dogs are excellent test subjects by which the potency of various diet factors for plasma protein regeneration can be measured. To regenerate plasma proteins in any significant amount the depleted dog requires food protein. Some proteins are very potent for new plasma protein production and others are utilized poorly. Beef serum is very potent and its proteins (2.6 gm.) will produce 1 gm. of new plasma protein in the depleted dog-a potency ratio of 2.6. Kidney protein stands at the bottom of our list and the dog needs 21 gm. of kidney protein to regenerate 1 gm. of plasma protein-a potency ratio of 21.0. Some grain proteins approximate the potency of beef serum and may show potency ratios of 2.7 to 4.6. Some of these grain proteins appear to favor the production of globulin more than albumin in the plasma. Skeletal muscle, gizzard (smooth muscle), lactalbumin and egg white fall into a favorable group with a potency ratio of 5.3 to 6.0. Whole liver, liver fractions, casein, and beef heart are a little less potent and present potency ratios of 6.5 to 8.0. Many of these food substances favor the production of albumin more than globulin. Pancreas and salmon muscle show less favorable potency ratios of 19.0 and 15.0 respectively. Fasting periods indicate that these depleted dogs can produce little if any new plasma protein. Iron feeding in some unexplained manner will influence body metabolism so that an excess of plasma protein will be produced. These observations have a bearing on clinical conditions associated with hypoproteinemia and give suggestions for diet aid or control in some of these abnormal states. The make-up of the diet is obviously of great interest and it is possible that protein combinations may be more potent than a single protein or that food potency ratios may differ in health and disease.
