ABSTRACT Vanillic mandelic acid (VMA), vanillic acid (VA) and homo vanillic acid (HVA) were determined in urine (collection period: 4 hours) of 11 controls, 7 patients with latent and 8 with manifest diabetes receiving sulfonyl urea, ACTH and Metopirone. The three investigated groups showed no difference in the elimination of VMA, VA and HVA during a test-free four hours period. After the application of sulfonyl urea the VMA and VA values were lowered in the diabetic group in contrary to the control persons, whereas the elimination of HVA remained unchanged. There was no difference in the HVA values between latent diabetics and controls. VA and HVA were somewhat increased after i. v. ACTH-application, VMA remained unchanged. In the diabetic group the three catecholamine metabolites were augmented up to twofold. Similar results were found during the endogenous ACTH-mobilisation by Metopirone where the diabetics also had the highest rise in VMA, VA and HVA. On account of these experiments it must be discussed that the sympathic-adrenal system of diabetics reacts more intensive to exogenous and endogenous ACTH.

Abstract Dietary manipulations to include tannins can change the proportion and amount of nitrogen (N) excreted in the urine and feces as well as improve N-use efficiency in ruminants. Our objective was to determine the effects of different levels of phytogenic supplementation (Actifor®) on intake, digestibility, carcass measures, and N balance of lambs offered a corn-based finishing diet. Twenty-six lambs (31.5 ± 5.39 kg BW) were allocated randomly to 1 of 3 corn-based finishing diets (85% concentrate) that were offered for ad libitum consumption. Lambs were housed individually in 1 × 1.5-m pens with plastic-coated grate flooring (n = 18; 6/trt) or 1.5 × 4.3-m pens with rubber mat flooring (n = 8; 2 or 3/trt). Diets were not supplemented or supplemented with 4 or 8 g/d of Actifor® (n = 8, 9, and 9 lambs/trt, respectively). A 7-d total fecal and urine collection period (n = 6 lambs/trt) began on d 43. On d 50, rumen samples were taken at 0800, 1100, and 1400 h for measurement of pH and VFA concentrations. Data were analyzed using the MIXED procedure of SAS, and orthogonal linear and quadratic contrasts were used to assess phytogenic supplementation level effects. Intake and digestibility of DM and OM were not different across treatments (P ≥ 0.32). Average fecal N and lamb shrink before slaughter increased linearly (P ≤ 0.05) with increasing levels of phytogenic supplementation. Propionate and acetate:propionate decreased (P ≤ 0.05) and acetate, valerate, and pH tended to increase quadratically (P ≤ 0.08) with increasing phytogenic inclusion. Back-fat and yield grade tended (P = 0.06) to decrease linearly and dressing percentage tended (P = 0.06) to decrease quadratically with increasing phytogenic inclusion. Phytogenic supplementation increased average fecal N and improved some carcass measures, but did not affect diet digestibility.

ABSTRACT Other investigators have reported that whole body clearance of thyroxine (T4) is increased in hyperthyroid rats isotopically equilibrated with radioactive T4, using the 24 h post-injection serum T4 concentration in the clearance calculation. Data from this laboratory indicate that serum T4 concentration is lowest at this point yielding falsely high clearance values, particularly when high doses of T4 are injected. To investigate this problem further, two types of experiments were performed. First, rats were equilibrated with [125I]T4, 5 or 20 μg/day, and the urinary clearance of iodide derived from T4 (deiodinative clearance) was measured from 0–7 and 7–24 h after a T4 injection, using the T4 concentration in serum obtained at the midpoint of each urine collection period. Urine was then collected from the ureters for several 1 h periods during the 4th to 8th h following T4 injection, calculating clearances using the midpoint plasma T4 concentration. Second, normal rats were given a single dose of [125I]T4, 5 or 55 μg/rat, and deiodinative clearance was determined during the subsequent 0–7 and 7–24 h periods. The first experiment indicated that deiodinative clearance was significantly enhanced in rats equilibrated with the large dose of T4 under all conditions studied. In contrast, the clearance in normal rats given a single large dose of T4 was not significantly different from that of normal rats given a small dose of T4. These results support the view that T4 clearance is increased in hyperthyroidism, due in part to an increase in the deiodination of T4.

Diabetes can be linked with impaired host immunity that subsequently increases the rate of various infections including tuberculosis (TB), particularly in developing countries where TB is endemic. The objectives of this case control study were to determine the prevalence and the risk of LTBI among diabetic patients. It is a prospective case control study conducted in Azadi Teaching Hospital from September 2017 until May 2018. The diabetic patients included in this study were randomly selected. The diagnosis of diabetes mellitus (DM) was made according to the American Diabetes Association (ADA). Diabetes mellitus patients and the control participants were offered a voluntary tuberculin skin test (TST). The TST ≥10 mm was considered positive. The results were analyzed by entering the data in SPSS (statistical package for the social sciences, version 16; SPSS Inc., Chicago, Illinois, USA). Two hundred DM patients and 208 control individuals participated in this study. Collectively, 28 patients had positive TST results. Based on the sputum smear microscopy and CXR, none of these patients showed active TB disease. The differences between the DM patients and the control group had no statistical significance apart from previous hospitalization. The prevalence of LTBI was 23.53% in the diabetic group, whereas, it was 9.62% in the control group. The frequency of LTBI in diabetic patients was significantly higher than the control group. When the diabetic group was compared with the control group in terms of diabetic control and the duration of diabetes disease, there was a statistically significant association of diabetes duration ≥ 10 years and TST positivity. In conclusion, the previous hospitalization was a significant risk factor for diabetic patients to acquire TB bacilli. Latent TB infection was more common in diabetics than non diabetics and there was an increased likelihood of having LTBI with the duration of diabetes ≥ 10 years. To avoid the threatening of TB control program, prophylactic treatment of LTBI in diabetic patients is paramount.Asian J. Med. Biol. Res. June 2018, 4(2): 227-232

Purpose: The purpose of this study was to determine the effects of diabetic complications on oxidation of proteins, lipids, and DNA and to investigate the relationship between oxidative damage markers and clinical parameters. Methods: The study group consisted of 69 type 2 diabetic patients (20 patients without complication, 49 patients with complication) who attended internal medicine outpatient clinics of Istanbul Education and Research Hospital and 19 healthy control subjects. In serum samples of both diabetic patients and healthy subjects, 8-hydroxy-2’deoxyguanosine (8-OHdG), as a marker of oxidative DNA damage, Nε-(hexanoyl)lysine (HEL) and 15-F2t-iso-prostaglandin (15-F2t-IsoP). as products of lipooxidative damage, advanced oxidation protein products (AOPP), as markers of protein damage, and paraoxonase1 (PON1) as antioxidant were studied. Results: 15-F2t-IsoP (p < 0.005) and AOPP (p < 0.001) levels were significantly higher in diabetic group than control group while there were no significant differences in levels of 8-OHdG and HEL between the two groups. AOPP (p < 0.001) and 8-OHdG (p < 0.001) were significantly higher in diabetic group with complications compared to diabetic group without complications. Conclusions: Increased formation of free radicals and oxidative stress, under conditions of hyperglycaemia, is one of the probable causes for evolution of complications in diabetes mellitus. Our study supports the hypothesis that oxidant/antioxidant balance is disturbed in diabetic patients.

ABSTRACT Background: Type 2 Diabetes Mellitus is a multifactorial syndrome with severe complications. Oxidative stress is accepted as a causal factor of chronic complications Aim: To demonstrate alterations in oxidative stress after metabolic surgery. Methods: Twenty-four 2-day-old Wistar rats were used. In 16, Type 2 Diabetes Mellitus was induced by 100 mg/kg streptozotocin injection. The development of diabetes was confirmed after 10 weeks using an oral glucose tolerance test. Eight diabetic rats composed the diabetic surgical group; the remaining eight composed the diabetic group. Eight animals in which diabetes was not induced formed the clinical control group. The Marchesini technique was used in the diabetic surgical group. After 90 days, the rats were sacrificed, and the oxidative stress markers were measured. Results: Thiobarbituric acid reactive substances, superoxide dismutase and catalase were significantly reduced in the diabetic surgical group compared to the diabetic group. Conclusion: The duodenojejunostomy was effective in controlling the exacerbated oxidative stress present in diabetic rats.

Metabolic disorders of the mother adversely affect early embryo development, causing changes in maternal metabolism and consequent alterations in the embryo environment in the uterus. The goal of this study was to analyse the biochemical profiles of embryonic fluids and blood plasma of rabbits with and without insulin-dependent diabetes mellitus (DT1), to identify metabolic changes associated with maternal diabetes mellitus in early pregnancy. Insulin-dependent diabetes was induced by alloxan treatment in female rabbits 10 days before mating. On day 6 post-coitum, plasma and blastocoel fluid (BF) were analysed by ultrahigh performance liquid chromatography-tandem mass spectroscopy (UPLC-MS/MS) (Metabolon Inc. Durham, NC, USA). Metabolic datasets comprised a total of 284 and 597 compounds of known identity in BF and plasma, respectively. Diabetes mellitus had profound effects on maternal and embryonic metabolic profiles, with almost half of the metabolites changed. As predicted, we observed an increase in glucose and a decrease in 1,5-anhydroglucitol in diabetic plasma samples. In plasma, fructose, mannose, and sorbitol were elevated in the diabetic group, which may be a way of dealing with excess glucose. In BF, metabolites of the pentose metabolism were especially increased, indicating the need for ribose-based compounds relevant to DNA and RNA metabolism at this very early stage of embryo development. Other changes were more consistent between BF and plasma. Both displayed elevated acylcarnitines, body3-hydroxybutyrate, and multiple compounds within the branched chain amino acid metabolism pathway, suggesting that lipid beta-oxidation is occurring at elevated levels in the diabetic group. This study demonstrates that maternal and embryonic metabolism are closely related. Maternal diabetes mellitus profoundly alters the metabolic profile of the preimplantation embryo with changes in all subclasses of metabolites.

Diabetes mellitus (DM) itself increases the risk of Coronary Artery Disease (CAD) by 2-4 fold and in out country we are treating a good number of patients having CAD with DM. On the other hand several studies have reported increased risk of adverse outcomes following balloon angioplasty in diabetic cases. In this situation this study had been carried out at National Institute of Cardiovascular Diseases (NICVD) cath lab to determine the immediate procedural success & in-hospital adverse outcomes in this population. In our study 100 cases were enrolled. Out of which, 40 patients had type II DM & rest were non-diabetic.Diabetic patients were compared with non- diabetic and found no major difference between the two patient group except for a higher number of LCX (Left Circumflex) lesion in the non-diabetic (25% VS 35%, P value 0.038). The lone case of renal complication came from the diabetic group. No MACE (Major Adverse Cardiovascular or Cerebrovascular Events) or death was occur in this series. Angiographic, procedural and clinical success in diabetic was 97.5%, 97.5% & 95% respectively whereas 100% found in non-diabetic group at its all segment. But this results are statistically insignificant and P value is 0.4000 for angiographic success, 0.4000 for procedural success and 0.158 for clinical success. P value for hospital stays is also insignificant i.e. 0.250 (while p value of < 0.05 was considered significant). Therefore in the setting of diabetes mellitus the outcomes of the stenting procedure are quite encouraging.
