1. The activities of the enzymes histidase, urocanase and histidine-pyruvate transaminase were studied in rats under conditions of protein malnutrition. Urocanase and histidase activities in liver were markedly lowered in experimental protein malnutrition, but the activity of histidine-pyruvate transaminase was unaffected. There is a metabolic control in vivo of the enzymes involved in the catabolism of histidine. 2. Significant changes in the urinary excretion of histidine, composition of liver and serum were apparent in the protein-malnourished rat. 3. The changes in the activities of the enzymes and other parameters were of a reversible nature and dependent on the nature of the dietary protein. 4. The significance of these findings is discussed in relation to abnormal histidine metabolism in kwashiorkor.

Abstract. Background: to evaluate the effects of Vitamin D3 on glyco-metabolic control in type 2 diabetic patients with Vitamin D deficiency. Methods: one hundred and seventeen patients were randomized to placebo and 122 patients to Vitamin D3. We evaluated anthropometric parameters, glyco-metabolic control, and parathormone (PTH) value at baseline, after 3, and 6 months. Results: a significant reduction of fasting, and post-prandial glucose was recorded in Vitamin D3 group after 6 months. A significant HbA1c decrease was observed in Vitamin D3 (from 7.6% or 60 mmol/mol to 7.1% or 54 mmol) at 6 months compared to baseline, and to placebo (p < 0.05 for both). At the end of the study period, we noticed a change in the amount in doses of oral or subcutaneous hypoglycemic agents and insulin, respectively. The use of metformin, acarbose, and pioglitazone was significantly lower (p = 0.037, p = 0.048, and p = 0.042, respectively) than at the beginning of the study in the Vitamin D3 therapy group. The units of Lispro, Aspart, and Glargine insulin were lower in the Vitamin D3 group at the end of the study (p = 0.031, p = 0.037, and p = 0.035, respectively) than in the placebo group. Conclusions: in type 2 diabetic patients with Vitamin D deficiency, the restoration of value in the Vitamin D standard has led not only to an improvement in the glyco-metabolic compensation, but also to a reduced posology of some oral hypoglycemic agents and some types of insulin used.

Effects of increased protein and energy provided by an intensified milk replacer on the antigen-specific, cell-mediated immune response of the neonatal calf were examined. Calves were fed a standard (0.45 kg/day of a 20% crude protein, 20% fat milk replacer; n = 11) or intensified (1.14 kg/day of a 28% crude protein, 20% fat milk replacer; n = 11) diet from 0 to 6 weeks of age. All calves were vaccinated with Mycobacterium bovis bacillus Calmette-Guerin (BCG) at 1 week of age. The daily weight gain of intensified-diet calves (0.62 kg/day) was greater than the weight gain of standard-diet calves (0.29 kg/day). Liver, kidney, heart, thymus, and subcervical lymph nodes from intensified-diet calves were heavier than the same organs from standard-diet calves. Flow cytometric analysis of peripheral blood mononuclear cell (PBMC) populations indicated that CD4+ cells, gamma delta TCR+ cells, and monocyte percentages, although unaffected by diet during the first 5 weeks of the study, were higher in intensified-diet calves at week 6. The decline in gamma deltad TCR+ cell percentages and increase in B cell percentages with increasing age seen in all calves are characteristic of the maturing immune system of the calf. CD8+ T cell or B cell percentages were not affected by diet. In intensified-diet calves, percentages of CD4+ expressing interleukin-2 receptor increased and percentages of gamma delta TCR+ cells expressing interleukin-2 receptor decreased with time. The same populations in standard-diet calves did not change with time. Percentages of CD4+ and CD8+ T cells, and B cells expressing MHC class II antigen, were unaffected by diet or age. Although mitogen-induced interferon (IFN)-gamma and nitric oxide (NO) secretion increased with age for all calves, PBMC from intensified-diet calves produced less IFN-gamma and more NO than did cells from standard-diet calves at week 6 of the study. Antigen-induced secretion of IFN-gamma and NO also increased with age but was unaffected by diet. Antigen-elicited delayed-type hypersensitivity was unaffected by diet, suggesting increased dietary protein and energy did not alter adaptive immunity in vivo. Overall, these results suggest that feeding calves a commercially available, intensified milk replacer affects minimally the composition and functional capacities of PBMC populations. Additional research is necessary to determine whether these subtle effects influence the calf’s susceptibility to infectious disease.

SummaryWe have previously shown that tight metabolic control by insulin therapy reduced thromboxane-dependent platelet activation in noninsulin-dependent diabetes mellitus (NIDDM) patients. The present study was undertaken to determine whether a similar effect could be obtained without switching diabetics in secondary failure to insulin treatment. For this purpose, we gave strict diet and exercise advise program and adjusted on a weekly basis the oral antidiabetic therapy (glipizide) that 26 patients with NIDDM had been given over the previous months.Basal measurements of urinary ll-dehydro-TXB2 and PAI-1 confirmed previous findings of enhanced levels of these parameters in NIDDM patients with macrovascular disease in comparison to age-and sex-matched controls. After 2-6 weeks, 16 patients achieved tight metabolic control associated with significant reduction of both thromboxane biosynthesis and PAI-1 levels; 10 patients remained in poor control and no significant decrease of both parameters was observed.We conclude that reduction of in-vivo platelet activation and PAI-1 antigen levels after metabolic improvement obtained by frequent reassessment of sulphonylurea therapy together with strict diet and exercise programs may have beneficial effects on the progression of diabetic micro- and macrovascular disease.

SummaryPlatelet-rich plasma was prepared from 47 patients with noninsulin-dependent diabetes treated with glibenclamide and metformin, and 21 controls. The release of radio-labelled 5-hydroxy-tryptamine in response to aggregating agents (adenosine diphosphate, adrenaline and sodium arachidonate), and the effects on release of a selective thromboxane inhibitor (UK-34787) were investigated. Subsequently, 20 of the diabetic subjects were chosen at random for treatment with insulin; the remainder continued to take tablets. Platelet studies were then repeated, in all patients, after 4 and 6 months.The results showed an association between platelet behaviour and the presence of vascular complications, and were consistent with previous observations of reduced platelet reactivity in patients taking sulphonylureas. There was no correlation of platelet reactivity with blood glucose, glycosylated haemoglobin or lipid levels.

Abstract. Residual insulin secretion, reflected by the presence of C-peptide in serum and urine, has been demonstrated in 5 of 10 insulin-requiring diabetics of less than 10 years' duration tested. The C-peptide response, in the C-peptide secretors, showed a significant increase in both serum and urine after 4 weeks' treatment with 15 mg glibenclamide daily in addition to their usual insulin regime although no beneficial effects in metabolic control were detected. It is suggested that glibenclamide might be a useful adjunct to insulin therapy in insulinrequiring diabetics who still secrete C-peptide.
