Grape Seed Proanthocyanidin

The effect of anabolic androgenic steroids on the cardiovascular system is poorly understood. Increased production of free radicals is coupled to the pathophysiology of many alterations within the circulatory system. The only function of the enzyme family NADPH oxidases (NOXs) is the generation of reactive oxygen species (ROS). Therefore, this study investigated the beneficial role of grape seed proanthocyanidin extract (GSPE) in ameliorating cardiac toxicity induced by the anabolic steroid Boldenone in male rats through NOX inhibition and reduction in the expression of NOX2 and NOX4. This study was conducted on forty male rats which are divided into four groups (normal control, positive control or GSPE, Boldenone, and posttreatment Boldenone with GSPE). A significant increase in relative body weight, relative heart weight, and hemodynamic parameters, as well as serum concentrations of lactate dehydrogenase, creatine kinase, creatine kinase-muscle brain, myoglobin, cholesterol, low-density lipoprotein cholesterol, risk factor 1/2, K+, and Cl−, in treated rats with Boldenone when compared with control. We also noted a significant increase in the levels of cardiac malondialdehyde, H2O2generation in heart tissues, mRNA expression of NOX2 and NOX4, and immunoreactivity to proliferating cell nuclear antigen (PCNA). Posttreated rats with Boldenone and GSPE ameliorated cardiac toxicity via inhibition of NOX and a reduction in alteration of the expression of NOX2, NOX4, and PCNA induced by Boldenone. These novel insights into the antioxidative activity of GSPE should serve as a basis for the development of improved chemopreventive or therapeutic strategies for cardiac toxicity.

Breast cancer remains the most common cause of cancer deaths among women globally. Ehrlich solid tumor (EST) is a transplantable tumor model for simulating breast cancer. This study aims to describe the protective role of costus (Saussurea lappa) root against EST-induced cardiac toxicity. Forty female mice were randomly and equally divided into four groups (G1, control group; G2, costus group; G3, EST group; G4, EST + costus). The results showed that compared to the control, EST induced a significant increase in lactate dehydrogenase, creatine kinase, creatine kinase myoglobin, aspartate aminotransferase, and alkaline phosphatase activities; in potassium, chloride ion, cholesterol, triglyceride, and low density lipoprotein levels; in DNA damage and cardiac injury; and in p53 and vascular endothelial growth factor expression. Conversely, EST induced a significant decrease in sodium ion and high density lipoprotein levels and Ki67 expression compared to the control. Treatment of EST with costus improved cardiac toxicity, lipid profiles, electrolytes, and apoptosis, and protected against EST. This indicates the potential benefits of costus as an adjuvant in the prevention and treatment of cardiac toxicity.

Doxorubicin (DXR) is a chemotherapeutic agent used effectively in the treatment of several childhood malignancies. During treatment, cardiotoxicity caused by cell damage due to the free oxygen radicals that are generated is a major limiting factor. This study was undertaken to determine whether DXR-induced cardiotoxicity could be prevented by natural foods with antioxidant properties such as aged garlic extract (AGEX), grape seed proanthocyanidin (PA), and hazelnut. Wistar albino male rats were assigned randomly to 9 groups each consisting of 15 rats. AGEX, PA, and hazelnut groups received these antioxidants in addition to their standard rat diet. They were also treated with cumulative intraperitoneal (i.p.) injections according to 2 different regimens: either a high-dose of 15 mg/kg DXR (3.75 mg/kg per week for 4 weeks) or a low-dose of 7.5 mg/kg DXR (1.875 mg/kg per week for 4 weeks). The control group received i.p. 0.9% saline. AGEX, PA, or hazelnut supplements were given orally to the groups for a 6-week period starting 1 week before the DXR treatment and ending 1 week after the treatment. One week after the last DXR injection, heart tissue samples were analyzed to determine malondialdehyde (MDA), superoxide dismutase (SOD), catalase (CAT), and xanthine oxidase (XO) levels, and serum samples were taken for creatine kinase (CK). There were no significant changes in MDA levels among the control, DXR-treated groups, or supplemented groups that received additional natural antioxidant foods. SOD enzyme levels were decreased in rats treated with DXR. PA prevented the decrease at low doses of DXR. DXR treatment decreased CAT enzyme levels, but additional PA and hazelnut consumption increased these levels at low cumulative doses. XO enzyme levels were decreased in AGEX and hazelnut groups, but PA prevented the decrease. CK levels were elevated after DXR administration, indicating myocardial injury, but PA significantly reversed this. Although there were no differences histopathologically between AGEX, PA, and hazelnut groups, the protective effects of AGEX and PA were evident in electron microscopy. In conclusion, the positive effects of natural antioxidant foods on the prevention of DXR-induced cardiac injury could not be clearly shown on the basis of antioxidant enzymes. However, the electron microscopic changes clearly demonstrated the protective effects of AGEX and PA. The supplementation of these antioxidant foods over longer periods may show more definitive results. Human studies with different doses are needed to evaluate the effects of these foods on the human heart.

ABSTRACT Background It is not clear whether dietary grape seed proanthocyanidin (GSP) affects mammalian lipid metabolism via the gut microbiota. Objective The aim of this study was to evaluate the contribution of the gut microbiota to the effect of dietary GSP. Methods This study was divided into 3 separate experiments using Duroc × Landrace × Yorkshire pigs (50% male) weaned at day 28 and then fed the same basal diet (NC). In Experiment 1, 90 pigs were fed NC or NC with 250 mg GSP/kg (GSP) or 400 mg betaine/kg [positive control (PC)] for 28 d. In Experiment 2, 30 pigs were fed NC, GSP, or GSP with antibiotics (GSP + Abx) diets for 14 d. In Experiment 3, pigs were fed NC, NC plus 1 g sodium propionate/kg (SP), or NC plus 1 g sodium butyrate/kg (SB) diet for 14 d. Serum biochemical indexes, SCFA concentrations, and microbial composition were determined. Results In Experiment 1, compared with the GSP group, visceral adipocyte area was higher in the NC (28.6%) and PC (18.2%) groups (P ≤ 0.05). Colonic propionate and butyrate concentrations were 30.2% and 3.6% higher in the GSP group than in the NC group, respectively (P ≤ 0.05). In Experiment 2, compared with the GSP group, the NC group had a 108% higher Firmicutes to Bacteroidetes ratio and had 50.4%, 61.2%, and 82.3% lower abundance of Akkermansia, Alistipes, and Bacteroides, respectively (P ≤ 0.05); antibiotics removed these effects of GSP. In Experiment 3, serum peptide YY was 19.5% higher in the SP group than in the NC group (P ≤ 0.05), and it did not differ between the SB and NC groups (P > 0.05). Conclusions GSP affected lipid metabolism in weaned pigs, which is associated with changed gut microbiota and enhanced microbial propionate production. These findings provide potential mechanisms for GSP intake to improve lipid metabolism.

Abstract Background During the last few decades, patients worldwide have been interested in using alternative medicine in treating diseases to avoid the increased side effects of chemical medications. Green coffee is unroasted coffee seeds that have higher amounts of chlorogenic acid compared to roasted coffee. Green coffee was successfully used to protect against obesity, Alzheimer disease, high blood pressure and bacterial infection. Methods This study aimed to investigate the probable protective activity of the green coffee methanolic extract, silymarin and their combination on CCl4-induced liver toxicity in male rats. Thirty Sprague – Dawley male albino rats were divided into 5 groups; control negative (G1) just got the vehicle (olive oil) and the other four groups received CCl4 dissolved in olive oil through an intraperitoneal injection and were divided into untreated control positive group (G2), the third group (G3) was treated with green coffee methanolic extract, the fourth group (G4) was treated with silymarin, and the fifth group (G5) was treated with a combination of green coffee methanolic extract and silymarin. Results In the positive control group treated with CCl4 (G2), the CCl4-induced toxicity increased lipid peroxidation, IL-6, kidney function parameters, liver function enzymes, total cholesterol, triglycerides and low-density lipoproteins, and decreased irisin, antioxidants, CYP450 and high-density lipoprotein levels. Hepatic tissues were also injured. However, treating the injured rats in G3, G4 and G5 significantly improved the altered parameters and hepatic tissues. Conclusions Green coffee methanolic extract, silymarin, and their combination succeeded in protecting the male rats against CCl4 hepatotoxicity due to their antioxidant activity. Effect of green coffee methanolic extract mixed with silymarin in G5 was more efficient than that of green coffee methanolic extract in G3 or silymarin in G4.

T3(3,5,3′-triiodothyronine) has drawn relatively little attention in relation to cardiovascular (CVS) diseases. The present study was designed to evaluate the cardioprotective action of T3in isoproterenol-(ISO-) induced cardiac toxicity. Female Wistar rats were exposed with ISO (100 mg/kg, body weight, subcutaneously) for 2 days at the interval of 24 h followed by T3(3 μg/kg, body weight, orally) treatment for 3 days. Positive control rats received only ISO (100 mg/kg, body weight, subcutaneously) for 2 days at the interval of 24 hrs. Control group animals received normal saline as a vehicle. As expected, ISO-induced significant changes were observed in low-density lipoprotein, total cholesterol, ALT, CK-MB to TCK ratio, and prolongation of QT interval in electrocardiogram, which is toward normalization after T3treatment. Lower heart weight, upregulation of cardiac myosin heavy chain alpha (MHC-α), and reduced inflammatory cell infiltration, myonecrosis, vacuolar changes, and a trend toward normal cardiac muscle fiber architecture in microscopic examination of cardiac tissue further support the cardioprotective effect of T3.

In the present study, the nutritional quality of four grains including adlay (AD), buckwheat (BW), glutinous barley (GB), and white rice (WR) were evaluated in terms of plasma lipid parameters, gut transit time, and thickness of the aortic wall in rats. The rats were then raised for 4 weeks on the high-fat diet based on the American Institute of Nutrition-93 (AIN-93 G) diets containing 1 % cholesterol and 20 % dietary lipids. Forty male rats were divided into 4 groups and raised for 4 weeks with a diet containing one of the following grains: WR, AD, BW, or WB. The level of thiobarbituric acid-reactive substances (TBARS) in liver was shown to be higher in rats by the order of those fed WR, AD, GB, and BW. This indicates that other grains decreased oxidative stress in vivo more than WR. The superoxide dismutase, glutathione, glutathione peroxidase, and glutathione reductase levels in the AD, BW, and GB groups were significantly higher than those in the WR group (p < 0.05). Plasma lipid profiles differed significantly according to grain combination, and decreased aortic wall thickness was consistent with the finding of decreased plasma low-density lipoprotein cholesterol (LDL-C) (p < 0.05) and increased high-density lipoprotein (HDL-C) in rats fed AD, BW, and GB (p < 0.001). The antioxidant and hypolipidemic capacities of grains are quite high, especially those of adlay, buckwheat, and glutinous barley. In conclusion, this study has demonstrated that the whole grains had a cardioprotective effect. This effect was related to several mechanisms that corresponded to lowering plasma lipids, decreasing TBARS, and increasing antioxidant activities.
