In cases of juvenile diabetes, there were lower than normal levels of reduced glutathione, ceruloplasmin oxidase activity, zinc, copper and sodium, while the other elements show no significant changes. The lower level of serum zinc, copper and sodium may be due to the osmotic diuresis and consequent polyurea of diabetes.

In this study, diabetes was induced by intravenous injection of dithizone. In dithizonised diabetic animals, the levels of serum zinc, iron, and potassium were found to be higher than normal, while those of serum calcium and sodium were lower. Copper and magnesium levels were unchanged. After treatment with insulin, most of these serum levels approached the normal, except for serum potassium and magnesium.

A young woman with diabetes mellitus developed chronic urticaria after changing from isophane been insulin suspension to isophane beef-pork insulin suspension. She reverted to treatment with her original insulin preparation, but urticaria failed to terminate. While in the hospital, her eruption began each afternoon at the site of insulin injection. Zinc single-peak beef insulin suspension, a purer preparation with different additives than isophane beef insulin, was substituted, and urticaria terminated rapidly. Intradermal skin testing using single-peak (purified) preparations indicated that the patient was sensitive to beef and pork forms of isophane insulin but not to beef and pork forms of zinc insulin. The patient later had a brief recurrence of urticaria following oral erythromycin and tetracycline therapy but did not develop lesions at sites of insulin injection.

Using carefully selected relatively non-obese non insulin dependent diabetic patients, we were not able to show differences in standard measures of insulin production or insulin action between patients treated with a long acting crystalline zinc insulin, with glibenclamide, or with metformin for a six week period. All three drugs were hypoglycaemic, but a fall in basal hepatic glucose output measured by the 3H3 glucose technique was only seen in those patients who had an initial fasting plasma glucose above 12.0 mmol/l, irrespective of treatment.

We studied in a group of elderly (mean age 77 yr) non-obese Type 2 diabetic patients (n = 9) in a randomised, placebo-controlled prospective cross-over study of 8 months duration, the effects of substituting maximal sulfonylurea medication with a single injection of human zinc insulin taken either at bedtime (BTI) or morning (MI). All patients were poorly controlled with oral antidiabetic agents. After a 2-month regimen with either BTI or MI, a glibenclamide (GL, 3.5 mg/day) was given for an additional 2 months. Both insulin regimens decreased mean diurnal blood glucose and glycosylated HbA1c values to a similar extent (2.6-2.7%; p < 0.01-0.05), but with a lower daily insulin dose with BTI (0.30 +/- 0.03 IU/kg) as compared with MI (0.39 +/- 0.05 IU/kg; p < 0.01). A further improvement in metabolic control was observed in both groups after the introduction of GL; the mean reduction in glycosylated HbA1c was 1.4% for BTI and 0.7% for MI (p < 0.01 and 0.05, respectively), In conclusion, a subgroup of poorly controlled elderly Type 2 diabetic patients showed an improvement in metabolic control after a single injection of insulin despite discontinuation of maximal doses of oral antidiabetic agents. After 2 months of insulin treatment, a further improvement was achieved by a low dose of sulfonylurea in these patients who were formerly considered unresponsive to oral antidiabetic agents.

This study was made to determine whether zinc deficiency is one of the factors involved in growth retardation of infants of high-risk pregnancies. The high risk factors were hypertension of pregnancy, diabetes mellitus, congenital heart disease, chronic nephritis, rheumatic heart disease and hyperthyroidism. 102 neonatal infants were divided into 3 groups: breast fed group, 37 cases; test group, 32 cases formula-fed with supplementary zinc 1.14-2.28 mg/kg/d; and control group, 33 cases formula-fed and supplemented with Vitamin B complex as placebo. The groups were divided by double-blind and randomized method. There were no differences in the 3 groups in sex ratio, growth status and serum zinc concentration at the beginning of the study. Anthropometric data were obtained at 0, 3 and 6 months.

Behind many clinical cases with recurrent, severe infections, absesses, delayed wound healing and especially in antibiotic resistant sepsis some granulocyte function abnormalities can be detected. The abnormalities are of inherited and acquired origin. The inherited dysfunctions are discussed here in details, but the appearance of some failures in neutrophil functions should be taken into consideration when examining patients with other diseases (e.g. diabetes, infections, periodontal disease, zinc deficiency, malignancies, uremia etc.). The main clinical tools for the diagnosis of the qualitative abnormalities in neutrophil functions are chemotaxis with migration, and an NBT test with and without stimulation, as a first indication. Any deviation in the result of these function tests requires further determinations.

The effects of diabetes and insulin administration on certain aspects of phosphoinositide metabolism in R3230AC mammary tumors were studied in vivo. Three weeks after diabetes was induced by streptozotocin, [3H]myoinositol incorporation into PI, PIP and PIP2 was increased in R3230AC tumors, whereas the formation of [3H]IP, [3H]IP2 and [3H]IP3 was decreased. Administration of protamine zinc insulin (3IU, twice daily, for 3 days) to diabetic rats decreased [3H]myoinositol incorporation into phosphoinositides and inositol phosphates in these mammary tumors. The R3230AC tumor from insulin-treated diabetic hosts had lower levels of unmetabolized [3H]-myoinositol compared to tumors from diabetic animals. Enzymatically-dissociated tumor cells from insulin-treated animals displayed decreased myoinositol transport in vitro. These findings suggest that the insulin-induced decrease in the turnover of inositol lipids in vivo in R3230AC mammary tumors could have resulted from the decreased level of [3H]myoinositol in these cells.

In the 235 patients with hepatectomy, 111 with pancreaticoduodenectomy (PD) and 547 with gastrectomy for the past 15 years and 5 months, we compared the incidence of postoperative complications between patients with diabetes mellitus (DM) and those without DM, and studied glucose metabolism and management of diabetic patients. DM was most frequently found at 27.7% in hepatectomy, especially 38.7% in cirrhotic patients, followed by 24.3% in PD and only 5.9% in gastrectomy. The incidence of postoperative complications was not different between DM and non-DM after gastrectomy and PD. It was significantly higher in DM than in non-DM after hepatectomy (38.5% vs. 11.8%), although there was no statistically significant difference in the cirrhotic patients with hepatectomy (34.9% vs. 23.5%). The studies on insulin metabolism preoperatively determined by oral glucose tolerance test and postoperative control of DM revealed that diabetic patients with hepatectomy, especially hepatogenous DM, had a significantly reduced insulin uptake in the liver and exogenous insulin resistance to glucose. After PD for diabetic patients, a long-term care of impaired pancreatic exocrine and endocrine functions was considered to be required, especially paying attention to lipid and zinc metabolism.

Many studies have shown that zinc deficiency could decrease the response to insulin. In genetically diabetic animals, a low zinc status has been observed contrary to induced diabetic animals. The zinc status of human patients depends on the type of diabetes and the age. Zinc supplementation seems to have beneficial effects on glucose homeostasis. However, the mechanism of insulin resistance secondary to zinc depletion is yet unclear. More studies are therefore necessary to document better zinc metabolism in diabetes mellitus, and the antioxidant activity of zinc on the insulin receptor and the glucose transporter.
