Silybum marianum: Beyond Hepatoprotection.
Silybum marianum is a medicinal plant that has long been used as hepatoprotective remedy. It has been used for the treatment of numerous liver disorders characterized by functional impairment or degenerative necrosis. Its hepatoprotective activity is unique and acts in different ways, including antioxidant and anti-inflammatory activities, cell permeability regulator and membrane stabilizer, stimulation of liver regeneration and inhibition of deposition in collagen fibers, which may lead to cirrhosis. Most of documented data with Silybum marianum are about liver disorders; however, recently several beneficial properties on a wide variety of other disorders such as renal protection, hypolipidemic and anti-atherosclerosis activities, cardiovascular protection, prevention of insulin resistance, especially in cirrhotic patients, cancer, and Alzheimer prevention. It is also used as a food remedy. This review article aims to present different aspects of Silybum marianum, especially the data in recently published articles about its effects on different diseases, apart from presenting the aspects of its hepatoprotection
Dissociation, reflexivity and habitus
Many theorists, in their search for a better explanation of the dynamics of structure and agency, have expressed the need for a theory in which reflexivity and habitus are reconciled. In this paper we argue that a dissociative theory of mind can provide the essential framework in which habitual routines and reflexivity function in parallel. This is explored using the examples of athletic training and hypnosis, where the interplay between conscious and unconscious mechanisms is displayed. In both settings, there is evidence to show that conscious reflexiveness and intersubjective and unconscious automatic processes are necessary to reach the desired outcome. We conclude that a dissociative theory of mind can shed new light on the relationship between habitus and reflexivity
Melissa officinalis L: A Review Study With an Antioxidant Prospective.
Melissa officinalis is a plant cultivated in some parts of Iran. The leaves of lemon balm, Melissa officinalis L (Lamiaceae), are used in Iranian folk medicine for their digestive, carminative, antispasmodic, sedative, analgesic, tonic, and diuretic properties, as well as for functional gastrointestinal disorders. This review article was aimed not only to introduce Melissa officinalis (its growth condition, its chemical compounds, and its traditional usages) but also to overview its antioxidant properties in detail. This review was carried out by searching studies in PubMed, Medline, Web of Science, and IranMedex databases up to 2016. The search terms used were "Melissa officinalis L," "antioxidant properties," oxidative stress," "oxidative damage", "ROS." Articles whose full texts were not available were excluded from the study. In this study, firstly, traditional usage of this herb was reviewed, including antimicrobial activity (antiparasitic, antibacterial, antiviral, etc), antispasmodic, and insomnia properties. Then, its antioxidant properties were overviewed. Various studies have shown that Melissa officinalis L possesses high amount of antioxidant activity through its chemical compounds including high amount of flavonoids, rosmaric acid, gallic acid, phenolic contents. Many studies confirmed the antioxidative effects of Melissa officinalis; thus, its effect in preventing and treating oxidative stress-related diseases might be reliable
The protective effect of garlic extract on diabetic nephropathy
Diabetes causes significant changes in urine and serum constituents such as albumin, creatinine, urea nitrogen, and glycated hemoglobin. Garlic extract, however, has been shown to restore all of these biochemicals, and cause histopathological changes. Administration of garlic extract or metformin, or their combinations has also been demonstrated to have both curative and protective effects against gentamicin nephrotoxicity. These findings can potentiate the clinical use of combinations of metformin and garlic extract in the prevention of diabetic nephropathy
Effect of Salvia officinalis on diabetic patients.
INTRODUCTION
Herbs are rich sources of natural antioxidants, and are used in traditional medicine for the control and treatment of many diseases. The reducing effect of a large number of these plants on blood glucose has been approved in animal models and clinical studies.
OBJECTIVES
This study was therefore, performed to investigate the hypoglycemic effect of Salvia officinalis on blood glucose, Glycosylated hemoglobin (HbA1c), lipid profile, liver and kidney function tests.
PATIENTS AND METHODS
A double-blind clinical trial was carried out on 80 type II diabetic patients who had not reached the ideal control of the disease. Patients were randomly divided into two equal groups of case and control. The case group received Salvia officinalis and the control group received placebo tablets three times a day for three months. The fasting blood sugar (FBS) and 2 hours postprandial (2hpp) glucose were checked at the beginning and every 2 weeks, for three months Glycosylated hemoglobin (HbA1c), lipid profile, liver and kidney function tests were also measured at the beginning and at the end of trial and compared in two mentioned groups.
RESULTS
The 2hpp blood sugar and cholesterol levels were significantly decreased in Salvia officinalis treated patients compared to control group (p<0.05). There were no significant changes in glycosylated hemoglobin and FBS between the two groups.
CONCLUSION
RESULTS showed that Salvia officinalis might be beneficial in diabetic patients to reduce 2hpp and cholesterol. However higher doses might be needed to decrease fasting blood glucose and glycosylated hemoglobin
Hyperuricemia aggravates IgA nephropathy
It is well documented that hyperuricemia is an independent risk factor for IgA nephropathy, and appropriate treatment by allopurinol is a reasonable modality in the patients. We believe that, this drug should routinely be included to the treatment of patients with IgA nephropathy. In this regard, to better understand the allopurinol kidney protective properties in IgA nephropathy, clinical studies are suggested
Association of Serum Uric Acid With Level of Blood Pressure in Type 2 Diabetic Patients
This study was conducted to investigate the association between serum uric acid level and blood pressure in type 2 diabetes mellitus. Sixty patients with type 2 diabetes mellitus were enrolled to the study. None of the patients had a history of gout, were treated with allopurinol, or were treated with antihypertensive drugs previously. The mean duration of DM was 9.2 +/- 4.9 years. The mean serum creatinine level was 0.98 +/- 0.22 mg/dL, and the mean serum UA level was 4.4 +/- 1.2 mg / dL. The mean protein level in 24-hour urine sample was 388 +/- 22 mg/ d. The mean systolic and diastolic blood pressure values were 133.0 +/- 13.0 mm Hg and 84.0 +/- 7.4 mm Hg, respectively. There was no significant difference in levels of serum uric acid, hemoglobin A1c, serum creatinine, proteinuria, or systolic and diastolic pressure between the men and the women. A significant positive correlation was seen between serum UA and systolic (r = 0.312, P = .02) and diastolic blood pressure (r = 0.297, P = .03). Results of this study suggest that serum uric acid had a strong association with levels of systolic and diastolic blood pressure in type 2 diabetic patients. More attention to the serum uric acid level and treatment of hyperuricemia could halt the progress of diabetic nephropathy
The protective effect of hydro-alcoholic extract of mangrove (Avicennia marina L.) leaves on kidney injury induced by carbon tetrachloride in male rats
Background: Materials can cause liver and kidney damage which carbon tetrachloride is one of these substances. Medicinal plants and their essential oils and extracts have been used to a large extent as drugs to better control and management of kidney diseases. Objectives: The aim of this study was to investigate the effect of hydro-alcoholic extract of Avicennia marina leaves in the treatment of renal toxicity induced by carbon tetrachloride. Methods: Forty-two male rats were randomly divided into 6 groups (n = 7): control (taking normal saline, 0.5 ml/day, intraperitoneally; i.p.), sham (taking olive oil, 0.5 ml/day, i.p., single dose), injury induced by carbon tetrachloride (CCl4) 1:1 with olive oil, 0.5 ml single dose, i.p.), treated groups 1, 2 and 3: by carbon tetrachloride 1:1 with olive oil, 0.5 ml single dose and 200 mg/kg, 400 mg/kg or 800 mg/kg Avicennia marina extract (AME)/ day for 96 hours, i.p.). By direct blood sampling from the heart, the plasma concentrations of lactate dehydrogenase, blood urea nitrogen (BUN), creatinine and liver enzymes including aspartate aminotransferase (AST), alanine aminotransferase (ALT), and alkaline phosphatase (ALP) were measured. Kidney sections were prepared from all groups and the histological examinations were performed. The results were analyzed using one-way analysis of variance (ANOVA). Results: The results indicated the significant (P < 0.05) increase of serum level of lactate dehydrogenase and liver enzymes of AST, ALT and ALP in the group receiving CCl4 compared with the control group, whereas the treatment with hydro-alcoholic extract of mangrove leaves caused a significant (P < 0.05) decrease in serum levels of these enzymes in rats treated with carbon tetrachloride compared to the control group. Histological investigation of renal tissue sections showed that the treatment with mangrove leaves extract reduced the necrosis, inflammation and also improved the renal tubules. Conclusions: Carbon tetrachloride has kidney, liver and cardiac toxicities and mangrove extract is able to inhibit the toxicities of carbon tetrachloride. © 2016 The Author(s)
Impact of oral vitamin D (Cholecalciferol) replacement therapy on blood pressure in type 2 diabetes patients; a randomized, double-blind, placebo controlled clinical trial
Background: Vitamin D is an important mediator of calcium metabolism. It has also been implicated as a potential contributor to the pathophysiology of various extra-skeletal conditions, consisting hypertension, renal disease, and insulin resistance. Objectives: The primary objective of this study was to determine whether oral vitamin D (cholecalciferol) supplementation can lead to improvement of blood pressure in type 2 diabetes patients. Patients and Methods: This study was a double blind clinical trial conducted on 60 type 2 diabetes mellitus patients. Exclusion criteria were taking calcium, vitamin D supplements or any drugs effecting calcium and vitamin D metabolism in the past 6 months. Patients were administered weekly vitamin D supplementation (50000 units) for 12 weeks. Serum 25-Hydroxy vitamin D 25(OH)D level was measured with ELISA method. Results: Five patients (8.3%) had vitamin D deficiency, 27 (45%) had insufficient levels of vitamin D and in 28 (45%) patients vitamin D level was within normal limits. The means of systolic blood pressure (BP) and diastolic BP in patients before intervention were 121 and 80.5 mmHg; after intervention they were 110 and 76.3 mmHg, respectively. After intervention, systolic and diastolic blood pressure levels were significantly less than control group (p< 0.01). Conclusions: In this study we found that weekly vitamin D supplementation (cholecalciferol; 50,000 units for 12 weeks) had beneficial effect on the level of blood pressure in type 2 diabetic patients. Thus, oral vitamin D may help in improvement of hypertension in these patients. © 2014, Society of Diabetic Nephropathy Prevention. All rights reserved
