1. Six weeks after the injection of streptozotocin at 125 mg/kg i.p. in the AV line nondiabetic Chinese hamsters, the animals showed hyperglycemia, increased kidney, pancreas and stomach weights and stomach glucagon contents and depletion of insulin and glucagon in the pancreas. 2. Plasma beta-D-galactosidase and N-acetyl-beta-D-glucosaminidase were elevated; whereas alpha-D-glucosidase was decreased and alpha-D-galactosidase remained unchanged in the plasma. 3. In the kidney, streptozotocin-diabetes led to depression of alpha-D-mannosidase, beta-D-fucosidase and N-acetyl-beta-D-glucosaminidase activities in both 12,000 g supernatant and precipitate fractions, decreases in alpha-D-glucosidase in the supernatant only and no change in alpha-L-fucosidase, alpha-D-galactosidase, beta-D-galactosidase and beta-D-glucuronidase. 4. In the liver, significant increases in N-acetyl-beta-D-glucosaminidase, alpha-D-galactosidase, beta-D-galactosidase, beta-D-fucosidase, beta-D-glucosidase and alpha-D-mannosidase were found in either the supernatant or the precipitate fraction of the diabetic animals. The data indicate diabetes-dependent tissue-specific changes in glycohydrolases in the Chinese hamster.

Streptozotocin treatment (125 mg/kg) in the Chinese hamster induced hyperglycaemia, hypoinsulinaemia, hyperglucagonaemia and changes in body, liver, pancreas, stomach, kidney and adipose tissue weights. The pancreatic reserves of insulin and glucagon in the diabetic animals were low, but stomach glucagon high. These animals showed high levels of phosphoenolpyruvate carboxykinase and low levels of glucokinase, hexokinase, isocitrate dehydrogenase and malic enzyme, but normal levels of pyruvate kinase in the liver. Increases in lactate dehydrogenase subunit B and isozymes 2, 3 and 4 were also observed in the liver, but not in the epididymal fat pad, of the diabetic animals. N-Acetyl-beta-D-glucosaminidase was elevated in plasma, liver and heart, but not in the kidney of the treated animals. Renal alpha-galactosidase and beta-glucosidase were depressed, whereas beta-galactosidase and alpha-glucosidase remained essentially normal. These features indicated that there were considerable differences between the biochemical disorders associated with streptozotocin-diabetes in the Chinese hamster and the published observations in the rat.

Inspection of the skin in its entirety often turns up initial and orientating symptoms allowing the early detection of internal disorders. For example, the painful ulcerations of pyoderma gangrenosum can provide clues as to the presence of underlying inflammatory bowel or joint or hematologic disturbances. Extremely painful ulcerations with livedoid bleeding located on the lower limbs are indicative of calciphylaxis as a serious complication of terminal renal failure. Periorificial and migratory necrolytic erythema may signal a glucagon-producing carcinoma of the pancreatic islet cells. Pasty, whitish-yellow papules on the face associated with a tendency for developing petechiae may be a manifestation of amyloidosis in a plasmacytoma. Numerous diffuse angiomas covering the body of a younger patient should prompt the physician to consider the genetic enzyme defect of alpha-galactosidase (Fabry's disease). In the case of pacemaker- or defibrillator-associated erythema, unnecessary revision of the device can be avoided if such possibilities are considered. In consultation with the dermatologist, the exact classification of symptoms, an accurate diagnostic work-up, and differential-diagnostic considerations should be undertaken with the aim of enabling early initiation of causal or stabilizing treatments.
