The Effects of Body Acupuncture on Obesity: Anthropometric Parameters, Lipid Profile, and Inflammatory and Immunologic Markers

A randomized controlled clinical trial in 196 obese subjects was performed to examine the effectiveness of body acupuncture on body weight loss, lipid profile and immunogenic and inflammatory markers. Subjects received authentic (cases) or sham (controls) acupuncture for 6 weeks in combination with a low-calorie diet. In the following 6 weeks, they received the low-calorie diet alone. Subjects were assessed at the beginning, 6 and 12 weeks later. Heat shock protein (Hsps)-27, 60, 65, 70 antibody titers and high sensitivity C-reactive protein (hs-CRP) levels were also assessed. A significant reduction in measures of adiposity and improvement in lipid profile were observed in both groups, but the levels of anti-Hsp-antibodies decreased in cases only. A reduction in anthropometric and lipid profile in cases were sustained in the second period, however, only changes in lipid profile were observed in the control group. Anti-Hsp-antibodies and hs-CRP levels continued to be reduced in cases but in controls only the reduction in hs-CRP remained. Changes in anthropometric parameters, lipid profile, and anti-Hsp-antibodies were more evident in cases. Body acupuncture in combination with diet restriction was effective in enhancing weight loss and improving dyslipidemia

Effect of hydro-alcoholic extract of Vaccinium arctostaphylos on insulin release from rat-isolated langerhans islets

Introduction: Vaccinium arctostaphylos is one of the medicinal plants used in the treatment of diabetes. But the mechanisms responsible for its antidiabetic action have not been well defined. This study was undertaken to investigate the possible effect of V. arctostaphylos on insulin release from rat-isolated Langerhans islets. Materials and Methods : The islets were incubated in the presence of 3 or 10 mM glucose with or without milrinone (0.1 and 0.01%) and hydro-alcoholic extract of V. arctostaphylos (0.1 and 0.1%) for 60 min. The concentration of insulin was measured in samples of incubation medium. Results: The increase of glucose concentration in incubation medium from 3 to 10 mM resulted in a significant increase of insulin secretion. Milrinone at 0.1 mM significantly increased insulin release evoked by 10 mM glucose. However, none of the extract concentrations affected the insulin release. Conclusion: Our data demonstrated that V. arctostaphylos had no insulinotropic property and its effects on diabetes mediated by other mechanisms which should be clarified in future studies

Effect of Ganoderma lucidum hydroalcoholic extract on insulin release in rat-isolated pancreatic islets

Objective: Ganoderma Lucidum (G. Lucidum) has been suggested to increase serum insulin level.This study was undertaken to investigateits direct effect on the islets of Langerhans. Material and Methods: Male albino Wistar rats were anesthetized and the islets were isolated after digestion of the pancreas with collagenase. The islets were incubated for 60 min in Krebs bicarbonate buffer containing 3 or 10 mM glucose in the presence of hydroalcoholic extract of G. Lucidum (1 mg/ml), 3-isobutyl-1-methylxanthine (IBMX, 100 µM) or vehicle. Results: Exposure of islets to the extract increased insulin secretion at basal (3 mM) glucose concentration. Increase of glucose concentration to 10 mM resulted in a significant increase in the rate of insulin secretion. While the IBMX could augment insulin release evoked by 10 mM glucose, the extract failed to modify it. Conclusion: Our results demonstrate that G. lucidum acts directly on the Langerhans islets to increase basal insulin release.

Effects of Ramadan Fasting on the Regulation of Inflammation

The month of Ramadan, as a model of intermittent fasting, is a valuable opportunity to investigate the effects of dietary modifications on human metabolism. Fasting improves insulin sensitivity, reduces atherogenic risk, oxidative stress, and inflammation. Inflammation plays a key role in the pathogenesis of different disorders including atherosclerosis, metabolic syndrome and cardiovascular diseases. Ramadan fasting can positively modulate cardiovascular risks and improves the metabolic syndrome features through suppression of inflammatory responses. In this review we attempt to present recent studies that addressed the regulatory role(s) of this nutritional status on inflammation in patients with inflammatory diseases. These studies suggest that the anti-inflammatory effect of fasting is significant and could be considered as a complementary therapeutic approach in treatment of inflammatory disorders in patients.Keywords: Ramadan fasting, Inflammation, Metabolic syndrome, Cardiovascular diseaseAbstract Abstract Abstract Abstract Abstract Abstract Abstract Abstract Abstract Abstract Abstract Abstract Abstract Abstract Abstract Abstract Abstract Abstract Abstrac

Serum selenium and glutathione peroxidase concentrations in Iranian patients with angiography-defined coronary artery disease

This study investigated the relationship between serum selenium (Se) and glutathione peroxidase (GPx) levels and the presence of coronary artery disease (CAD) among Iranian patients. Three groups were compared: patients undergoing angiography with angiographically defined CAD, individuals with a normal angiogram, and apparently healthy controls with no evidence of overt CAD. Anthropometric measurements, blood pressure, fasting blood glucose and lipid profiles, serum Se and GPx measurements, and angiographic assessment were carried out using standard protocols. Mean serum Se concentrations were not significantly different between patients with and without CAD and the control group. The mean value of serum GPx in the control group was significantly higher than in patients with or without CAD. Selenium status did not differentiate between patients with and without CAD, which may be related to the fact that angiography is not a very sensitive index of global atherosclerosis, and it is possible that patients who were CAD negative by angiogram still have significant disease. It may also be that Se is not a good marker of CA

Association between C-reactive protein, pro-oxidant-antioxidant balance and traditional cardiovascular risk factors in an Iranian population

Background: Inflammatory states are known to cause an imbalance in the redox status. We aimed to study the possible associations between pro-oxidant-antioxidant balance (PAB) and serum high-sensitive C-reactive protein (hs-CRP) concentrations and traditional cardiovascular disease (CVD) risk factors in an unselected Iranian population and in groups of individuals with specific disease. Methods: The study was conducted among an unselected population of 758 male subjects. Biochemical markers, including hs-CRP and PAB values, were measured. Results: Serum hs-CRP concentrations were positively associated with serum PAB values (r = 0.260, P <= 0.001). Univariate analysis showed that PAB values were statistically higher in individuals who were obese or smokers compared with non-obese and non-smokers individuals (P < 0.01). While serum hs-CRP concentrations were significantly higher in older subjects, subjects with obesity, diabetes mellitus, metabolic syndrome, central obesity, hypertriglyceridaemia, higher low-density lipoprotein cholesterol concentrations, positive history of CVD and lower physical activity than subjects without these risk factors (P < 0.05). Comparing hs-CRP and PAB values in different CVD risk score subgroups showed a significant incremental rise in both parameters as CVD risk score increased (P < 0.05). Using multiple linear regression analysis we found a strong association between PAB values and hs-CRP concentrations. Conclusions: This study showed that among Iranian subjects, the inflammatory marker, hs-CRP, was strongly and positively associated with a marker of oxidative stress and also with several traditional risk factors of CVD. Moreover, the impact of traditional cardiovascular risk factors on hs-CRP concentrations and PAB values differed

Cardiovascular Risk Factors and Nutritional Intake are not Associated with Ultrasound-defined Increased Carotid Intima Media Thickness in Individuals Without a History of Cardiovascular Events

Background: Carotid ultrasound appears to be useful in the assessment of cardiovascular risk. In this study, we have assessed the carotid intima-media thickness (CIMT) in a group of individuals without a history of cardiovascular events. Methods: A sample of 431subjects (189 [43.9%] males and 242 [56.1%] females) was obtained from an urban population using a stratified-cluster method in Mashhad stroke and heart atherosclerosis disorder study. None of the subjects had a history of the cardiovascular event. Carotid artery duplex ultrasound was used to determine the CIMT in all subjects, and to identify those with an abnormal value (CIMT [+]; i.e., CIMT ≥ 0.8 mm). Dietary intake of participants was assessed using a questionnaire for 24-h dietary recall. The relationship between anthropometric, biochemical and dietary data and CIMT were assessed. Results: The mean age of subjects was 48.7 ± 8.0 years. Of the 431 patients, 118 (27.4%) were found to be CIMT (+). Of the cardiovascular parameters assessed, only age (odds ratio [OR] [95% confidence interval (CI)], 1.11 [0.56-4.34]; P < 0.01) and male gender (OR [95% CI], 1.14 [0.63-2.23]; P < 0.05) were significant independent predictors of ultrasound defined CIMT. Crude and total energy adjusted intake were not associated with the presence of CIMT (+). Conclusions: It appears that within a relatively young Iranian population of individuals without a history of cardiovascular event, the presence of CIMT (+) defined by duplex ultrasound cut-off value of ≥0.8 mm, did not associate with several modifiable cardiovascular risk factors or measures of dietary intake

Changes in small dense low-density lipoprotein levels following acute coronary syndrome

Low-density lipoprotein (LDL), especially small dense LDL (sdLDL), plays a role in atherogenesis. We compared baseline sdLDL levels between healthy controls and patients with acute coronary syndrome (ACS). Blood samples were taken from patients diagnosed with myocardial infarction ([MI] n = 104) and unstable angina ([UA] n = 100). Both sdLDL and high-sensitivity C-reactive protein (hsCRP) levels were determined on admission and in the next 24 hours after the onset of symptoms. Baseline concentration of sdLDL was significantly higher in patients presenting with ACS than controls (P .05). The changes in sdLDL values were not significantly different between MI and UA participants (P > .05). Patients with ACS have higher concentration of sdLDL compared with the controls

Changes in pro-oxidant-antioxidant balance after bare metal and drug eluting stent implantation in patients with stable coronary disease

OBJECTIVES In this study we aimed to assess the changes in pro-oxidant-antioxidant balance (PAB) after the placement of either a drug-eluting-stent (DES) or bare-metal-stent (BMS) in patients with stable coronary artery disease. DESIGN AND METHODS Percutaneous coronary interventions (PCI) with either BMS or DES were undertaken for 152 patients (82 in the BMS and 70 in the DES groups respectively). PAB values were measured 24h before and after PCI. RESULTS Baseline PAB values were 80.68 (64.98-99.37) and 98.86 (64.70-140.62) for BMS and DES group, respectively, which were not significantly different between the 2 groups (P>0.05). Following PCI, median PAB values decreased to 72.10 (61.40-96.13) and 81.40 (54.15-121.90) in BMS and DES groups, respectively. The reduction was significant in both BMS and DES groups (P0.05). CONCLUSION We found that the reported difference in clinical outcomes following DES or BMS implantation cannot be attributed to differences in early changes in oxidative stress induction as assessed by changes in PAB values

Depression and anxiety both associate with serum level of hs-CRP: a gender- stratified analysis in a population-based study

Background: Depression and anxiety are two important mood disorders that are frequently associated with chronic diseases such as cardiovascular diseases (CVDs). Hyper-inflammation is related to both CVDs and psychological conditions such as depression and anxiety. Therefore, inflammation may partially explain the relationship between depression and cardiovascular disease. Objective: The objective of this study was to perform a gender-stratified examination of the association between symptoms of depression/anxiety disorders and serum hs-CRP and inflammation linked conditions in a large Iranian population. Methods: Symptoms of depression and anxiety disorders and serum hs-CRP levels were measured in 9759 participants (40% males and 60% females) aged 35–65 years, enrolled in a population-based cohort (MASHAD) study in north-eastern Iran. Symptoms of depression and anxiety were evaluated with Beck Depression and Anxiety Inventories. According to the scores of depression and anxiety, individuals were categorized into four groups of no or minimal, low, moderate and severe categories. Results: The median serum hs-CRP concentration increased with increasing severity of depression and anxiety disorders. Male participants with severe depression had significantly higher levels of hs-CRP (p < 0.001); however, this relationship was less marked among women (p = 0.04). Subjects with severe anxiety also had significantly higher levels of hs-CRP (p < 0.001). Moreover, women with severe depression and anxiety had higher BMI. There was also a positive association between current smoking habit and depression/anxiety disorders. Conclusion: Depression and anxiety disorders are associated with elevated levels of hs-CRP, particularly among men. Also, there is a significant positive association between depression/anxiety disorders and inflammation linked conditions such as smoking and obesity; however, in the case of obesity this association is only present in women
