Objectives: The present study assessed the effects of cinnamon on the activity of the liver CYP2D1 enzyme and hepatic clearance in the rat model of type 1 and 2 diabetes mellitus. Methods: Male Wistar rats were randomly categorized into 8 groups. Fourteen days after induction of diabetes type 1 and 2, type 1 groups received cinnamon and insulin plus cinnamon and type 2 groups received cinnamon and metformin plus cinnamon daily for 14 days. On day 28, rats were subjected to liver perfusion by buffer containing dextromethorphan as the CYP2D1 enzyme activity probe. Perfused samples were analyzed by high-performance liquid chromatography (HPLC) with fluorescence (FL) detection to evaluate the CYP2D1 activity and hepatic clearance. Results: In the control group, enzyme activity and hepatic clearance changed from 0.0081 ± 0.00009 and 6.09 ± 0.2 mL/min to 0.0059 ± 0.0001 and 3.71 ± 0.07 mL/min in the untreated type 1 diabetic rats and to 0.0006 ± 0.0001 and 5.19 ± 0.02 mL/min in untreated type 2 ones. These pharmacokinetic (PK) parameters changed to 0.0069 ± 0.0005 and 6.27 ± 0.06 mL/min in treated type 1 and 0.0115 ± 0.0003 and 5.79 ± 0.11 mL/min in the treated type 2 rats with only cinnamon administration. Treatment with cinnamon plus insulin or metformin modulated these PK parameters to 0.0039 ± 0.00006 and 4.88 ± 0.13 mL/min in type 1 and 0.0092 ± 0.0005 and 6.13 ± 0.01 mL/min in type 2 diabetic rats. Conclusions: Cinnamon can act as an effective complementary medicine in order to normalize the metabolism and clearance processes in diabetes mellitus.

Background. It is well known that intramammary arterial calcifications diagnosed by mammography as a part of generalized diabetic macroangiopathy may be an indirect sign of diabetes mellitus. Hence, the aim of this study was to determine the incidence of intramammary arterial calcifications, the patient?s age when the calcifications occur, as well as to observe the influence of diabetic polineuropathy, type, and the duration of diabetes on the onset of calcifications, in comparison with nondiabetic women. Methods. Mammographic findings of 113 diabetic female patients (21 with type 1 diabetes and 92 with type 2), as well as of 208 nondiabetic women (the control group) were analyzed in the prospective study. The data about the type of diabetes, its duration, and polineuropathy were obtained using the questionnaire. Statistical differences were determined by Mann-Whitney test. Results. Intramammary arterial calcifications were identified in 33.3% of the women with type 1 diabetes, in 40.2% with type 2, and in 8.2% of the women from the control group, respectively. The differences comparing the women with type 1, as well as type 2 diabetes and the controls were statistically significant (p=0.0001). Women with intramammary arterial calcifications and type 1 diabetes were younger comparing to the control group (median age 52 years, comparing to 67 years of age, p=0.001), while there was no statistically significant difference in age between the women with calcifications and type 2 diabetes (61 years of age) in relation to the control group (p=0.176). The incidence of polineuropathy in diabetic women was higher in the group with intramammary arterial calcifications (52.3%) in comparison to the group without calcifications (26.1%), (p=0.005). The association between intramammary arterial calcifications and the duration of diabetes was not found. Conclusion. The obtained results supported the theory that intramammary arterial calcifications, detected by mammography could serve as markers of co-existing diabetes mellitus and therefore should be specified in radiologic report in case of their early development.

The structural and functional features of the microcirculatory heel (MCB) were studied in patients with arterial hypertension (AH) in relation to the presence or absence of type 1 diabetes mellitus (DM). Two hundred and twelve patients were examined. These included 110 patients with grades 1 and 2 arterial hypertension (AH) and type 2 DM, 82 patients with AH without type 2 DM, and 20 apparently healthy individuals. Laser Doppler flowmetry (LDF) was used to estimate basal blood flow, the loading test parameters characterizing the structural and functional status of MCB, and the incidence of hemodynamic types of microcirculation. Patients with AH concurrent with type 1 DM were found to have the following microcirculatory features: an increase in perfusion blood flow (microcirculation index, 8,8±1,8 perf. units versus 4,9±0,8 perf, units in patients with AH without DM and 6,7±0,9 perf. units in the control group), a drastic reduction in myogenic activity to 13,2±5,7 % versus 16,7±6,8 and 25,2±6,4 %, respectively, a decrease in vascular resistance, impairment of autoregulation, and low reserve capacities (reserve capillary blood flow was 197,8±31,6 % versus 429,9±82,01 % in the group of AH without DM and 302,8±50,1 % in the control group), a predominance of the hyperemic hemodynamic type (58,8 % in patients with AH and DM, 20,9 % in those with AH without DM, and 20,0 % in the controls). The specific features of the altered microcirculatory bed in patients with AH concurrent with type 2 DM were ascertained. These included the predominance of hyperemic microcirculation, impaired autoregulation. diminished microvascular resistance, and the low reserve capacities of the microcirculatory bed.

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.

Diabetes mellitus is the most common endocrine disorder worldwide and it is usually along with complications such as retinopathy, neuropathy, nephropathy, and cardiovascular disease. The prevalence of diabetes is increasing and its treatment has created concerns in society. The use of herbal medicine can be helpful in the management of diabetes mellitus. The aim of this study was to investigate the protective effect of marigold hydroalcoholic extract under diabetes condition. A total of 36 male Wistar rats were randomly divided into four groups: normal control group, diabetic control group, and groups treated with 250 or 500 mg/kg hydroalcoholic extract of marigold flower during four weeks. At the end of the study, the rats were anesthetized with ketamine/xylazine, and sampling was performed through cardiac puncture. The results showed that treatment with marigold improved body weight. In addition, we determined that marigold normalized the level of CK-MB, total CK, amylase, and lipase in a dose-dependent manner. Probably these effects resulted from antioxidant property of marigold; thus we suggest that marigold flower can be useful for reduction of diabetes complication.

AIM: This work was done to study the effect of both types of diabetes mellitus (DM) on myocardial contractility in rats. Also, we investigated the role of treatment of DM with insulin and rosiglitazone (used as treatment for type 1 and type 2 DM respectively) in improvement of myocardial dysfunction in diabetic rats.METHODS: The study included 50 male Wistar albino rats, divided into 5 groups: control (group I), streptozotocin induced type 1 DM (group II), fructose induced type 2 DM (group III), insulin treated type 1 diabetic rats (group IV) and rosiglitazone treated type 2 diabetic rats (group V). At the end of the study, retro-orbital blood samples were withdrawn and blood glucose, plasma triglyceride (TG), total cholesterol (TC) and thyroid hormones levels were measured. Rats were then anesthetized and their hearts were excised and connected to Langendorff apparatus to perform mechanical cardiac performance tests including heart rate (HR), left ventricular developed pressure (LVDP) and maximum rate of pressure rise (+dp/dt).RESULTS: Data of the study showed that relative to control group, there was significant increase in blood glucose, plasma TG and TC levels while, thyroid hormones and myocardial performance parameters showed significant decrease in both type 1 and type 2 diabetic rats. Treatment of type 1 diabetic rats with insulin and type 2 with rosiglitazone resulted in significant decrease in blood glucose, plasma TG and TC levels associated with significant improvement in thyroid hormones and myocardial performance parameters. The results also showed that insulin treatment of type 1 was more effective in ameliorating all parameters than treatment of type 2 by rosiglitazone.CONCLUSION: We concluded that the induction of both types of diabetes resulted in decreased myocardial performance parameters. The  treatment of type 1 and type 2 diabetes by insulin and oral rosiglitazone respectively improved to a great extent the altered metabolism and  mechanical myocardial parameters, with more improving effect of  insulin in type 1 than rosiglitazone in type 2 DM.

Diabetes mellitus (DM) is a metabolic disorder that results from insufficient secretion or insulin resistance, or both. Insulin secretion deficiency leads to chronic hyperglycemia along with impaired metabolism of proteins, lipids, and carbohydrates. This study aimed to investigate the TP53 gene SNP (single nucleotide polymorphism) rs1042522 genotype and the interleukin-6 (IL-6) gene SNP rs1800795 genotype in DM and control groups. This study was performed on 70 patients with type 1 DM, 100 patients with type 2 DM without related complications, 66 control subjects for type 1 DM, and 95 control subjects for type 2 DM. The control groups were matched regarding age and gender and did not have a familial relationship with the patient groups. All the subjects were residents of Kermanshah, located in the western part of Iran. Polymorphisms of TP53 and IL-6 genes were determined by the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. Lipid profile, fasting blood glucose, and HbA1c were measured using the ELISA and immunoturbidometric methods. The frequency of genotypes (CC, CG, GG) of the TP53 gene codon 72 in type 1 DM and its control group were significantly different (P= 0.013). Likewise, the frequency of genotypes (CC, CG, GG) of the TP53 gene codon 72 was significantly different between type 2 DM and control groups (P <0.001). The frequency of genotypes (GG, GC, CC) of G174C polymorphisms in the IL-6 gene was different between type 1 DM and control group as well as between type 2 DM and its control group, but it was not statistically significant. SNP rs1042522 genotypes in the dominant form (CG + GG vs. CC) (OR= 3.880; P < 0.001) and alleles G vs. C alleles (OR= 0.384; P < 0.001) increased the risk of type 2 DM significantly. There was no significant difference between type 1 and type 2 DM groups and respected control groups regarding the frequency of the IL-6 gene SNP rs1800795 alleles. The G allele of SNP rs1042522 encoding the TP53 gene increases the risk of developing DM in the population of the Kermanshah province, Iran.

Background: Diabetes mellitus is a chronic metabolic disorder that develops due to insulin deficiency or insulin resistance. Recent animal and human studies have reported bromocriptine to be effective in the management of type 2 diabetes mellitus. The present study was done to evaluate the antihyperglycemic effect of bromocriptine in dexamethasone induced hyperglycemic rats.Methods: Male wistar rats were used and divided into 5 groups. Dexamethosone was used to induce hyperglycemia in group B-E. Group A was the untreated control group, group B was the standard control group, group C was the oral 10 mg/kg of bromocriptine dissolved in 0.9% normal saline, group D was the oral 20 mg/kg metformin dissolved in 0.9% normal saline, group E was the oral 10 mg/kg bromocriptine+20 mg/kg metformin dissolved in 0.9% normal saline. Fasting blood glucose, post prandial blood glucose and body weight was estimated on day 1, 15, 30.Results: It was seen that dexamethasone induced hyperglycemia and increase in body weight in male wistar rats, which were significantly controlled by oral bromocriptine and bromocriptine with metformin combination.Conclusions: Results obtained from this study showed that bromocriptine can be a promising drug with novel mechanism to treat type 2 diabetes mellitus.

Introduction/Objective. Hand functions have an enormous impact on activities of daily living in patients with diabetes mellitus (DM), such as self-care, administering insulin injections, and preparing and eating meals. The aim of the study was to evaluate hand functions and grip strength in patients with type 1 and type 2 DM. Methods. This was an observational case-control study investigating the hand functions and grip strength in patients with type 1 and type 2 DM. The study comprised 41 patients with type 1 DM aged 25?50 years sex- and age-matched, 40 non-diabetic controls, and 91 patients with type 2 DM aged 40?65 years sex- and age-matched 60 non-diabetic controls. Patients with documented history of diabetic sensorimotor neuropathy and adhesive capsulitis were excluded. The Duruoz Hand Index was used to assess the functional hand disability. Grip strength was tested with a calibrated Jamar dynamometer. Results. The Duruoz Hand Index scores in patients with type 2 DM were significantly higher than in persons in the control group (p < 0.01), but there was no significant difference between the type 1 DM and the control group (p > 0.05). Grip strength values of patients with type 1 DM were significantly lower compared to those in the control group (p < 0.05), whereas there was no significant difference between patients with type 2 DM and their control group. There was a negatively significant correlation between grip strength and the Duruoz Hand Index scores in patients with both type 1 and type 2 DM (p < 0.05). Conclusion. Patients with type 1 DM and type 2 DM have different degrees of hand disability as compared to healthy control groups.

Insulin therapy, a corner stone of the treatment of diabetes mellitus, both type 1 and type 2, has undergone substantial modification since the manufacture of the first insulin preparations 90 years ago up to the present time. Human insulins, such as neutral protamin Hagedorn (NPH) insulins, remain a major instrument of therapy of diabetes mellitus despite rapid developments in this field of knowledge and the wide availability of insulin analogs. When prescribing these preparations, the attending physician should be absolutely confident that the patient has a minimum background of knowledge and skills indispensable for efficacious and safe treatment. Such skills include the habit of mixing NPH insulin suspensions by 20-fold turning the vial or the cartridge upside-down or rolling them between the palms in order to ensure the uniform distribution of insulin in the suspension and its accurate dosing. The manufactures place from one to three glass or metal bullets inside the vials and cartridges for more homogeneous mixing of their contents. P. Kaiser et al. undertook the study of several pharmaceutical forms of NPH insulin manufactured by different companies to estimate the accuracy of dosing (variability of the insulin dose depending on the number of turns of the cartridge for homogeneous mixing). The insulin concentration in a single dose was measured by high-performance liquid chromatography. Marked variability of the insulin dose after less than ten (three or six) turns was documented for all cartridges with the exception of Insuman Basal insulin cartridges ("Sanofi"). It may be expected that the accuracy of dosing will not deteriorate using these cartridges owing to the presence in them of three heavy metal bullets even if the patient does not perform the necessary mixing procedure for one or another reason.

A successful treatment of dental implant needs a good jaw bone support, which depends on healthy bone metabolism. Bone metabolism can be affected by Diabetes Mellitus (DM). It may trigger various complications, including osteoporosis. Molecular triads consisting of Receptor Activator of NF-kappaB (RANK), Activator of nF-κB Ligand (RANKL), and osteoprotegerin (OPG), have an important role in the formation, function, and osteoclast survival. In this study, molecular triads were observed on mandible and femur bones in type 2 DM Wistar rats. The aim of this study was to observe the molecular triad RANK / RANKL / OPG expressions in type 2 DM Wistar rats. This laboratory research used 18 male Wistar rats divided into three groups: nondiabetic group (control), uncontrolled DM injected with single dose of Streptozotocin (STZ), and controlled DM treated with Metformin. On day 20, the mandible and femur were collected and specimen processing was carried out. The results of RANK / RANKL / OPG expressions were obtained from immunohistochemical staining. In both mandible and femur groups, RANK, RANKL, OPG expressions showed no difference between the control and uncontrolled DM groups. RANKL / OPG ratio in uncontrolled DM was higher than that in the control group. RANK expression was lower in uncontrolled DM group compared with controlled DM, and the RANKL expression in uncontrolled DM group was higher than that in the controlled DM group. RANKL / OPG ratio was lower in the controlled DM group. The study suggested that DM affects resorptive activity in mandible and femur bones which can be observed via RANK/RANKL/OPG.
