Effects of Citrullus colocynthis L. in a rat model of diabetic neuropathy / 中西医结合学报

OBJECTIVE@#This study investigated the biochemical, histopathological and physiological effects of Citrullus colocynthis on peripheral neuropathy in rats with streptozotocin (STZ)-induced diabetes.@*METHODS@#Seventy adult male Sprague-Dawley rats were included in the present study. Diabetes was induced in 60 rats, with a single intraperitoneal injection of STZ (65 mg/kg). After 4 weeks, the diabetic rats were assessed for neuropathy. Then, the diabetic rats with neuropathy were randomly divided into 6 groups for a 4-week treatment with gabapentin, oral administration of C. colocynthis fruit pulp powder (100 and 300 mg/kg per day), topical preparations as oil-based solution and ointment, or placebo. Changes in metabolic, physiological, biochemical and histological parameters were considered as treatment outcomes.@*RESULTS@#Metabolic outcomes (body weight and blood glucose level) were improved in the C. colocynthis-treated groups as compared to placebo. Tail-flick and hot-plate tests also had lower latency in the C. colocynthis-treated groups. Measurement of oxidative stress markers (malondialdehyde, superoxide dismutase and catalase) showed the antioxidant effect of C. colocynthis. Histological evaluation of the sciatic nerve showed that C. colocynthis decreased the number of demyelinated and degenerated nerve fibers. Among the C. colocynthis-treated groups, the one receiving 100 mg/kg power per day orally had the best treatment outcomes.@*CONCLUSION@#The present study showed that C. colocynthis fruit, through its antioxidant and hypoglycemic activities, has a positive effect in the treatment of diabetic neuropathy.

Rhus coriaria L. increases serum apolipoprotein-A1 and high-density lipoprotein cholesterol levels: a double-blind placebo-controlled randomized clinical trial / 中西医结合学报

<p><b>BACKGROUND</b>Lipid-lowering effect of Rhus coriaria L. (Rhus) has been investigated in multiple animal studies with promising results. Nonetheless, its clinical efficacy has not been adequately examined.</p><p><b>OBJECTIVE</b>The aim of this study was to evaluate the lipid-lowering effects of Rhus among patients with hyperlipidemia.</p><p><b>DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS</b>The study was designed as a two-arm, double-blind placebo-controlled randomized clinical trial, using a parallel design. Eighty patients with primary hyperlipidemia were randomly assigned to receive Rhus capsules or placebo for 6 weeks.</p><p><b>MAIN OUTCOME MEASURES</b>The serum lipid levels, apolipoprotein-A1 (Apo-A1) and apolipoprotein-B (Apo-B) were measured.</p><p><b>RESULTS</b>Mean serum high-density lipoprotein cholesterol (HDL-C) and Apo-A1 levels were significantly increased in the Rhus group, compared with the placebo group, after 6 weeks of intervention (P = 0.001). The analysis of covariance test including age, gender, body mass index (BMI), and smoking as co-variables revealed that the increase in HDL-C and Apo-A1 levels remained significant, and increases in HDL-C were dependent on the increase in Apo-A1 levels. No significant difference was observed between Rhus and placebo groups in terms of mean reductions in total cholesterol, low-density lipoprotein cholesterol and triglyceride levels; however, more significant improvement was observed among obese patients (BMI ≥ 30 kg/m).</p><p><b>CONCLUSION</b>The study showed significant increases in HDL-C and Apo-A1 levels in response to Rhus supplementation in patients with hyperlipidemia.</p><p><b>TRIAL REGISTRATION</b>ClinicalTrials.gov ID: NCT02295293.</p>

Complementary and alternative medicine use in Iranian patients with diabetes mellitus / 中西医结合学报

<p><b>OBJECTIVE</b>There is increasing interest in complementary and alternative medicine generally, and especially by those affected by chronic diseases, such as diabetes mellitus. We aimed to determine the prevalence and pattern of complementary and alternative medicine use among patients suffering from diabetes mellitus in Shiraz, southern Iran. Another objective was to explore associated factors for use of complementary and alternative medicine among patients with diabetes mellitus.</p><p><b>METHODS</b>A 19-item semi-structured questionnaire (open- and close-ended) was administered to 239 patients with diabetes mellitus in this cross-sectional study. It was carried out in two outpatient diabetes clinics affiliated with the Shiraz University of Medical Sciences, Shiraz, Iran.</p><p><b>RESULTS</b>One hundred and eighty patients (75.3%) used at least one type of complementary and alternative medicine in the last year prior to the interview. Patients with diabetes mellitus who were living in a large family (≥5 members), not taking insulin, and believed that complementary and alternative medicine have synergistic effects with conventional medicine, were independently and significantly (P values: 0.02, 0.04, and 0.01, respectively) more likely to use complementary and alternative medicine. Most of the users (97.7%) reported use of herbal preparations, and 89.4% of users did not change their medication, neither in medication schedule nor its dosage.</p><p><b>CONCLUSION</b>The use of complementary and alternative medicine, especially herbal remedies, is popular among diabetes patients in Shiraz, Iran. This use is associated with patients' family size, type of conventional medications and their view about concomitant use of complementary and conventional medicine.</p>

relationship between serum adiponectin levels with the presence and severity of coronary artery disease

Adiponectin plays important roles in the endocrine and cardiovascular systems, in fat and carbohydrate metabolism, and inflammation. In this study the relationship between adiponectin levels with the presence and severity of coronary artery disease [CAD] is evaluated. This was a cross-sectional study that enrolled 213 persons who referred for coronary angiography. One cardiologist reported the results of each coronary angiography by using two scoring systems [number of vessel disease [usual method] and Gensini scoring system]. Then, the relationship between adiponectin levels with the presence and severity of CAD as well as predictive factors for CAD were evaluated. There was a significant negative association between mean serum adiponectin levels and presence of CAD [P - 0.04] after adjustment for all conventional risk factors for CAD. Also there was a significant negative correlation between serum adiponectin levels and severity of CAD based on the usual method for reporting coronary angiograms [P = 0.01]. After adjustment for all conventional risk factors for CAD the serum adiponectin level tended to be inversely associated with the Gensini score [P= 0.09]. Logistic regression analysis showed that a higher serum adiponectin level was negatively and independently associated with CAD [odds ratio: 0.94; 95% confidence interval: 0.88-1 .00; P < 0.05]. The variables predictive of serum adiponectin levels were determined as follows: HDL-cholesterol [P= 0.001]; age [P- 0.002]; insulin resistance [P = 0.005] and triglycerides [P = 0.036]. This cross-sectional study showed a significant negative association between serum adiponectin levels to the presence and severity of CAD

[Risk factors of diabetes mellitus in Shiraz city, 2007]

Type 2 diabetes mellitus is the most common type of diabetes which is triggered by various factors such as obesity, hyperlipidemia, hypertension, dietary habits and inheritance. With respect to geographic variation of diabetes prevalence, it is important to know the risk factors regionally. As a case-control study, we looked for important risk factors of diabetes in our region. This study consisted of 400 individuals in case group and 400 individuals in control group. All these anthropometric measurements were calculated by standard methods. Blood samples taken from two groups were studied for TG, FBS, Cholesterol and HbA1c. Data are reported as the Mean +/- SD. P<0.05 was considered as statistically significant. There was no significant difference between two groups about mean age and sex ratio. Statistically significant difference were found for central obesity, hyperlipidemia, hypertension, polycystic ovarian syndrome [PCOS] and positive family history of diabetes in both groups [P<0.05]. The results showed that central obesity, hyperlipidemia, hypertension, PCOS and positive family history of diabetes are important risk factors of diabetes mellitus in Shiraz. In concordance with the results of this study, screening programme for that risk factor of diabetes in this region is suggested
