Abstract

Background & objectives: Iron overload is involved in the pathophysiology of many diseases including diabetes. In fact, the excess iron by creating free radicals makes damage to pancreas and leads to insulin resistance and diabetes. Andrographolide extract has hypoglycemic and antioxidant properties. This study has surveyed the effects of andrographolide on blood glucose and lipid profile in rats with secondary iron overload.

Methods: In this experimental study, 36 male Wistar rats were randomly divided into 6 groups: the healthy control group, secondary iron overload group, secondary iron overload groups treated with a dose of 3.5 and 7 mg/kg of andrographolide extract, and andrographolide groups treated with a dose of 3.5 and 7 mg/kg of extract. Iron and extract were injected for 6 and 12 days, respectively. Blood samples were taken for measurement of blood glucose and lipid profiles. Data were analyzed using ANOVA test.

Results: The pathological results of samples from liver of animals receiving iron showed that the iron was deposited in the liver tissues. Iron injection significantly increased blood glucose levels compared to healthy control group (p<0.05). In the iron overload group, andrographolide extract with a dose of 3.5 mg/kg or 7 mg/kg significantly decreased blood glucose levels (p<0.05). Iron injections did not increase the serum triglyceride and cholesterollevels. Injections of andrographolide extract with a dose of 3.5 mg/kg and 7 mg/kg, significantly decreased the cholesterol levels compared to iron receiving group (p<0.05).

Conclusion: Results of this study showed that the andrographolide with different doses may be effective in the treatment of diabetes by reducing serum glucose and cholesterol levels.

Abstract

Background & objectives: Andrographolide has potent antioxidant properties. There is still not a complete understanding of the antioxidant effects of andrographolide. In this study, the effect of andrographolide on the serum antioxidant activity of superoxide dismutase and catalase was investigated in the rats with secondary iron overload. 
Methods: In this experimental study, 32 rats were divided into 4 groups of 8 each. The groups included: 1-Control 2- Receiving iron 3- Receiving iron treated with 7 mg/kg andrographolide 4- Receiving 7 mg/kg andrographolide. The serum activity of superoxide dismutase and catalase and serum level of malondialdehyde (MDA) was measured using colorimetric method. Prussian blue was used to evaluate iron deposition in liver.
Results: The results showed that iron was deposited in the liver. The activity of superoxide dismutase and catalase in the secondary iron receiving group, compared to control group, was significantly increased (p<0.05). The activity of catalase was significantly decreased in the group receiving iron and treated with andrographolide, compared to the control and iron receiving groups (p<0.05). Also, the activity of superoxide dismutase in the group receiving iron and treated with andrographolide decreased significantly compared to the iron receiving group (p<0.05). Serum levels of malondialdehyde in the iron receiving group were higher than the control group (p<0.05). Serum levels of malondialdehyde in the group receiving iron and treated with andrographolide, compared with the iron receiving group, showed a significant decrease (p<0.05).
Conclusion: Andrographolide (7mg/kg) reduced the serum activity of catalase and superoxide dismutase and malondialdehyde serum levels in rats with secondary iron overload.

Abstract

Background & objectives: Due to the widespread use of zinc oxide nanoparticles (ZnO-NPs) and their possible unwanted effects in biological environments, we made an attempt to investigate the effect of ZnO-NPs on the blood lipid profile.
Methods: In this study, 24 male Wistar rats were used. The rats were randomly divided into three groups: control group, the group receiving ZnO-NPs at 25 mg/kg (ZnO-NPs 25 mg/kg) and the group receiving ZnO-NPs at 50 mg/kg (ZnO-NPs 50 mg/kg). The duration of the test was two weeks. The blood samples were taken and the serums were separated. Serum levels of triglyceride, cholesterol, VLDL, LDL and HDL were determined using standard kits and methods.
Results: Based on the findings of this study, serum levels of triglyceride and VLDL in both ZnO-NPs receiving groups were significantly increased in comparison with the control group (p<0.05). Also,  the serum levels of HDL , LDL and LDL/HDL ratio decreased significantly in both ZnO-NPs receiving groups compared to the control group (p<0.05), while the  serum cholesterol levels did not change compared with the control group.
Conclusion: Our results showed that 25 and 50 mg/kg doses of ZnO-NPs had both harmful (increase triglyceride and VLDL and reduction of HDL) and beneficial (reduction of LDL and LDL/HDL ratio) effects on the blood lipid profile.

Abstract

 
Background & objectives: One of the most important diabetes complications is chronic renal failure. This disorder is one of the most important progressive renal problems that is closely associated with high mortality rate in diabetic patients. The purpose of this study was to evaluate the effect of conjugated blackcurrant extract and  zinc oxide nanoparticles on histopathologic damages of kidney tissue in diabetic rats.
Methods: A total of thirty adult Wistar rats were used and they were randomly divided into the following six groups (n=5): control group; diabetic group (170 mg/kg alloxan); diabetic group treated with insulin (170 mg/kg alloxan & 10 U/kg insulin); diabetic group treated with ZnO nanoparticle (170 mg/kg alloxan & 8 mg/kg ZnO nanoparticle); diabetic group treated with extract (170 mg/kg alloxan & 150 mg/kg blackcurrant extract) and diabetic group treated with extract conjugated with ZnO nanoparticles (170 mg/kg alloxan & 8 mg/kg blackcurrant extract conjugated with ZnO nanoparticle). Diabetes mellitus was induced by intraperitoneal injection of alloxan monohydrate. Conjugated blackcurrant extract and ZnO nanoparticles were produced using green synthesis method. The tissues were stained with hematoxylin and eosin stain. Image J software was used for evaluation of histopathological changes.
Results: The comparison between groups treated with blackcurrant extract, ZnO nanoparticles and blackcurrant extract conjugated with ZnO nanoparticle showed that these compounds somewhat protect kidney tissue from diabetes damage . The highest protective effect was observed in diabetic group treated with ZnO nanoparticles conjugated with blackcurrant extract.
Conclusion: Our study, for the first time, showed that the conjugation of blackcurrant extract to ZnO nanoparticles can be effective in preventing renal- tissue damage in diabetic patient.

Abstract

 
Background & objectives: Chronic Obstructive Pulmonary Disease (COPD) is accompanied by systemic inflammations and is characterized by irreversible airflow limitations. Leptin is a cytokine with pre-inflammatory effect. However, there have been no studies on the effect of conjugated linoleic acid (CLA) on the serum leptin concentration in COPD patients. Therefore, the present study aimed to explore the effect of CLA on the serum leptin level, lung function and quality of life in COPD patients.
Methods: This interventional study was conducted on 90 COPD patients. The patients were randomly divided into two groups (supplement and placebo) with 45 patients per group. After obtaining written consent from the patients and recording their demographic characteristics, the spirometry was performed and COPD assessment test (CAT) score was calculated. Moreover, a fasting blood sample was collected from each of them in order to analyze their serum leptin concentration. After that, the patients in the supplement group were administered with 3.2 g/day of CLA for 6 weeks. The patients in another group received placebo. After the intervention, spirometry, CAT score calculation and blood sampling were repeated for all of the patients and the obtained results were analyzed.
Results: after the intervention, a significant decrease both in the serum leptin level and in CAT score as a quality life marker  was observed in the supplement group (p<0.05). Moreover, the FEV1 levels as a lung function test, increased significantly in the supplement group after the intervention (p<0.05). Although, the difference between the two groups was not significant.
Conclusion: The use of CLA supplement can improve COPD patients’ quality of life through decreasing the serum level of leptin in their blood.
