Low-dose bedtime insulin therapy in combination with oral hypoglycemic agents (OHAs) has become an alternative treatment for NIDDM subjects with secondary failure to OHA. To assess its clinical efficacy, patient compliance, and its possible side effects, 33 patients with secondary OHA failure were recruited in this study. All of the subjects had experienced poor glycemic control for at least six months on their maximal OHAs before the institution of the bedtime insulin injection. Monotard HM (human insulin zinc suspension) was given at an initial dose of 0.15-0.2 U/kg body weight and was adjusted thereafter. As a whole, low-dose bedtime insulin with OHAs improved glycemic control. According to the clinical response, 10 patients (30.3%) were graded as responders, 12 (36.4%) were partial responders, 10 (30.3%) were non-responders, and one (3%) discontinued insulin therapy. There was no difference in demographic features among these three groups of patients. During this period, eight (25%) cases experienced mild hypoglycemic symptoms. In conclusion, combination of OHAs with a low-dose bedtime insulin injection is an alternative therapy for NIDDM patients with OHA failure.

The Zn/Cu ratio was examined in the serum of three groups of persons: healthy volunteers, diabetic patients on diabetic diet (NIDDM), and diabetic patients on diabetic diet and insulin (IDDM). Zinc, copper, the Zn/Cu serum ratio, and the blood glucose level were determined during fasting and 2 h after breakfast. Zn and Cu serum levels in NIDDM and IDDM patients were decreased. The Zn/Cu ratio was higher in both groups of diabetic patients. These changes in the Zn and Cu levels as well as in the Zn/Cu ratio were not related to chronic diabetic complications.

Zinc status was assessed in 53 diabetic patients: 18 insulin-dependent diabetic patients (IDDM), 22 noninsulin-dependent diabetic patients (NIDDM) treated with oral antidiabetic agents, and 13 insulin-treated, noninsulin-dependent diabetic patients (IRDM). Plasma zinc concentrations were in the usual range for healthy subjects in these three groups (15.3 +/- 0.9 mumol/L). Urinary zinc excretions were elevated in the IDDM group (18.3 +/- 4.1 mumol/24 h; p less than 0.01 vs normal) and in the NIDDM group (17.5 +/- 3.5 mumol/24 h; p less than 0.01 vs normal), but normal in the IRDM group (11.3 +/- 2.4 mumol/24 h). In 14 NIDDM patients treated with transient continuous sc insulin injections, urinary zinc decreased from 16.5 +/- 2.2 mumol/24 h before insulin treatment to 11.5 +/- 0.3 mumol/24 h after insulin treatment without any modification in plasma zinc concentrations.

The tensile bond strength of noble and non-noble castings luted with adhesive resin cements and zinc phosphate cement to prepared extracted teeth having received MOD amalgam restorations were compared. The crown preparations were standardized on the extracted teeth to produce axial wall length and taper consistent with that seen clinically. Results indicated the resin luting agents were significantly more retentive than the zinc phosphate cement and for each cement there was no difference in the casting alloy used.

Zinc is known to have important effects on insulin activity, to increase the body fat deposition, and thyroid hormones conversion (T4 to T3). It is also known to have intestinal absorption competition between zinc and copper. This study was to investigate the blood zinc and copper concentrations in NIDDM and obesity, the relationships among metals, insulin, and thyroid hormones were also determined. Blood samples of diabetic, obese, and healthy individuals were collected between 9-10 AM, and the blood levels of zinc, copper, insulin, T4 and T3 were assayed. The results showed that diabetics and obese individuals had higher insulin and T3 levels than healthy controls, but there was no difference in T4. The obese had lower serum zinc concentration. There were low levels of copper both in serum and erythrocyte, and a low erythrocyte zinc concentration in NIDDM. Blood zinc concentration was inversely related to T3 level in diabetics and obese individuals. It is suggested that zinc, insulin and T3 may have considerable correlations in the thermoregulation on NIDDM and obesity, and the true mechanisms still need more further studies in the future.

Decreased serum zinc levels and hyperzincuria occur in some non-insulin dependent diabetic subjects (NIDDM). Zinc deficiency was demonstrated in various tissues of animal models for NIDDM. Serum zinc and 24-hr urine zinc of subjects with NIDDM were compared with that of age- and sex-matched healthy volunteers. Zincuria was significantly increased in the diabetic group. Thirteen diabetic subjects with hyperzincuria and hypozincemia were supplemented with zinc sulfate 220 mg x 3/day for 7-8 weeks. At the end of the study, glucose disposal (evaluated by kg) decreased significantly from 0.562 +/- 0.03 to 0.414 +/- 0.05 (p less than 0.05) and fasting glucose and fructosamine were significantly increased from 177 +/- 10 mg/dl to 207 +/- 15 mg/dl (p less than 0.05) and from 2.7 +/- 0.2% to 3.2 +/- 0.28% (p less than 0.05), respectively. T-lymphocyte response to phytohemagglutinin was increased significantly. We conclude that zinc supplementation to NIDD patients with hypozincemia and hyperzincemia might aggravate their glucose intolerance. More accurate methods to assess zinc deficiency in NIDD patients is needed to justify the supplementation of zinc in these patients.

The early life environment, 24 h nutrient intake, body mass index, blood pressure and plasma zinc levels among 42 non-insulin dependent diabetic subjects living in sheltered housing were compared to 126 age and sex matched controls from the same community. A high body mass index and systolic blood pressure were the only risk factors. The association with systolic blood pressure was present only among non-obese subjects. No difference in nutrient intake was found. When nutrient intake from all 427 subjects living in sheltered housing was compared to other countries with a higher prevalence of NIDDM, the diet of Chinese subjects consisted of a lower percentage of fat calories and a higher percentage of protein and carbohydrate calories.

The majority of zinc, copper and magnesium is either intracellular or associated with the bones. It is therefore unlikely that the plasma concentration of these trace elements will reflect their whole body content. Blood cells might be more representative of lean tissue and are also easy to obtain. The concentration of zinc, copper and magnesium was measured in the leukocytes and hemoglobin of 42 subjects with non insulin dependent diabetes mellitus (NIDDM) and in 22 subjects with insulin dependent diabetes mellitus (IDDM) and was compared with that of 44 age-matched healthy volunteers. Zinc was found to be deficient in the serum (p less than 0.001), leukocyte (p less than 0.001) and hemoglobin (p less than 0.05) of the IDDM subjects, while copper and magnesium were increased in the serum, leukocytes and hemoglobin of the IDDM subjects (p less than 0.001). There was no zinc deficiency in the leukocytes of NIDD subjects. These results are opposite to the findings on zinc concentration in various tissue of animal models for IDDM and NIDDM and with our present knowledge on zinc status in IDDM and NIDDM subjects. Thus, we conclude that the concentration of zinc in blood cells of diabetic subjects might not reflect its concentration in various tissues.

The concentrations of magnesium, potassium and zinc were determined in plasma, erythrocytes, muscle biopsies, and in urine collected during 24 hours, in 18 subjects with type II diabetes mellitus (DM). Magnesium was also determined in mononuclear cells. The results were compared with those in 35 (magnesium and potassium analyses) or 26 (zinc analyses) healthy controls. Subjects with type II DM had lower concentrations of magnesium (3.79 +/- 0.32 vs. 4.29 +/- 0.22 mmol/100 g FFDS), potassium (40.5 +/- 5.17 vs. 46.1 +/- 3.81 mmol/100 g FFDS) and zinc (231 +/- 29 vs. 247 +/- 23 ng/mg FFDS) in skeletal muscle. Furthermore, the urinary excretions of magnesium and zinc were higher, as compared with those in healthy controls (5.00 +/- 2.68 vs. 3.62 +/- 1.47 mmol/24 hours, and 683 +/- 285 vs. 326 +/- 205 micrograms/24 hours, respectively). The contents of magnesium, potassium and zinc plasma did not correlate with the corresponding concentrations in skeletal muscle or circulating blood cells, as investigated in healthy controls, diabetics and in all subjects together, implying that the plasma concentrations are not useful in the assessment of electrolyte status. Hence, deficiency of electrolytes frequently occurs, and should be looked for, in subjects with type II DM.

Diabetes mellitus is a chronic metabolic disorder, which can alter the nutritional status of the individual. Some micronutrients, in particular zinc and chromium, have been implicated in the pathogenesis of carbohydrate intolerance. This review evaluates the available published data on the status of 10 mineral elements and seven vitamins in diabetic patients and experimental animal models of diabetes. The role of these micronutrients in insulin secretion and carbohydrate metabolism is discussed in an attempt to determine whether the reported alterations in serum or tissue content of minerals or vitamins contribute to the carbohydrate intolerance of diabetic patients. It is concluded that both Type I and Type II diabetes mellitus can result in changes in certain micronutrients. However, adequately controlled studies to establish the role of trace elements in the pathogenesis of diabetes mellitus are not available.
