    ABSTRACT: Ethanol metabolism is known to induce overwhelming production of reactive oxygen species (ROS) and also to cause associated immune dysfunction. Several interventional agents of plant origin, in particular fruits and vegetables have been used to counteract these alterations induced by ethanol. In this study, we investigated the efficacy of dietary feeding of skin and flesh of grapes (Vitis vinifera L.) on the alterations in immune and vascular functions in mice with liver abnormalities induced by chronic ethanol consumption. Results revealed that feeding of both grape skin and flesh (2.5 g/kg body wt/day) effectively attenuated the oxidative stress and alterations in immune function and angiogenesis induced by chronic ethanol consumption (1.6 g/kg body wt/day for 12 weeks) in mice. The antioxidant actions of the grape skin and flesh as observed in this study might be attributed to the polyphenols present in the grapes.

    ABSTRACT: Ethanol metabolism induces generation of excessive amount of reactive oxygen species (ROS) which results in immune dysfunction. We examined the efficacy of silymarin on ethanol-induced oxidative stress, immunomodulatory activity, and vascular function in mice blood. Effectiveness of silymarin was compared with potent antioxidant ascorbic acid. In the present study, 8- to 10-week-old male BALB/c mice (20-30 g) were divided into the four groups of six each. One group were fed with ethanol (1.6 g/kg body weight), while second group were fed with ethanol (1.6 g/kg body weight) and silybin (250 mg/kg body weight), and the third group were exposed to ethanol (250 mg/kg body weight) and ascorbic acid (250 mg/kg body weight) per day for 12 weeks. The control group was fed with isocaloric glucose solution instead of ethanol. Ethanol exposure significantly increased thiobarbituric acid reactive substance (TBARS) and nitrite levels besides glutathione-S-transferase (GST) activity, and significantly decreased reduced glutathione (GSH) content and the activities of superoxide dismutase (SOD), catalase (CAT), glutathione reductase (GR), and glutathione peroxidase (GPx) in whole blood hemolyzate, while silymarin treatment significantly normalized these altered parameters. Silymarin significantly prevented ethanol-induced, elevated activities of interleukin (IL)-10, tumor necrosis factor (TNF)-α, γ interferon (IFN-γ), vascular endothelial growth factor (VEGF)-A, and transforming growth factor (TGF)-β1, as well as decreased IL-4 activity in mice blood. These results were comparable with the activity of ascorbic acid.

    ABSTRACT: Angiogenesis, the growth of new blood vessels, is essential during tissue repair. Though most molecular mechanisms of angiogenesis are common to the liver and other organs, there was no report available whether alcoholic liver disease also causes angiogenesis. In this study, we examined the effects of long term ethanol (1.6 g/kg body weight/day) consumption on angiogenic responses in the liver of male Wistar strain albino rats (16-18 weeks old, weighing 200-220 g) up to 36 weeks. Chronic ethanol consumption was associated with not only elevated oxidative stress, and altered cytokines expression, but also developed large von Willebrand factor, fibrosis and activation of matrix metalloproteinases. Moreover, vascular endothelial growth factor-receptor 2 (VEGF-R2, fetal liver kinase 1: Flk-1/KDR) expression and neovessel generation in the rat liver were noted after 36 weeks of ethanol consumption. Thus our study provides novel evidence that long-term ethanol consumption is associated with angiogenesis through delicate and coordinated action of a variety of mediators.

    ABSTRACT: Apoptosis plays an important role in cellular homeostasis. In this study we have investigated whether apoptosis is a contributory factor to alcohol induced liver damage. Long term ethanol (1.6 g/kg body weight/day) exposure augmented liver apoptosis as reflected by high frequency of positive TUNEL staining nuclei and by an increased activity of caspase-3 and -8. Our study provides evidence that long-term ethanol consumption triggers apoptotic process in the liver.

    ABSTRACT: Alcohol abuse is a systemic disorder. The deleterious health effects of alcohol consumption may result in irreversible organ damage. By contrast, there currently is little evidence for the toxicity of chronic alcohol use on lung tissue. Hence, in this study we investigated long term effects of ethanol in the lung. Though body weight of rats increased significantly with duration of exposure compared to its initial weight, but there was no significant change in relative weight (g/100 g body weight) of lung due to ethanol exposure. The levels of thiobarbituric acid reactive substances (TBARS), nitrite, protein carbonyl, oxidized glutathione (GSSG), redox ratio (GSSG/GSH) and GST activity elevated; while reduced glutathione (GSH) level and activities of glutathione reductase (GR), glutathione peroxidase (GPx), catalase, superoxide dismutase (SOD) and Na(+)K(+) ATPase reduced significantly with duration of ethanol exposure in the lung homogenate compared to the control group. Total matrix metalloproteinase activity elevated in the lung homogenate with time of ethanol consumption. Histopathologic examination also demonstrated that severity of lung injury enhanced with duration of ethanol exposure. 16-18 weeks old male albino Wistar strain rats weighing 200-220 g were fed with ethanol (1.6 g/ kg body weight/ day) up to 36 weeks. At the end of the experimental period, blood samples were collected from reteroorbital plexus to determine blood alcohol concentration, and the animals were sacrificed. Various oxidative stress related biochemical parameters, total matrix metalloproteinase activity and histopathologic examinations of the lung tissues were performed. Results of this study indicate that long term ethanol administration aggravates systemic and local oxidative stress, which may be associated with lung tissue injury.

    ABSTRACT: Adhesion molecules play an important role in the pathogenesis of several diseases. In this study, expression of adhesion molecules was examined in the setting of chronic alcohol induced liver damage of male albino Wistar strain rats (16-18 weeks-old, 200-220 g) in a time dependent manner. Decreased protein level and increased activities of liver marker enzymes in response to the chronic ethanol (1.6 g ethanol/kg body weight/day) exposure, indicated that these animals suffered from liver damage in a time-dependent manner. Flow cytometric analysis revealed that chronic ethanol treatment induced intercellular adhesion molecule-1, vascular cell adhesion molecule-1 and platelet endothelial cell adhesion molecule-1 expression in liver tissues of rats with duration of ethanol exposure. The results suggest that the adhesion molecules may be associated with the initiation of hepatic injury during alcohol intoxication.

    ABSTRACT: The metabolism of ethanol gives rise to the generation of excess amounts of reactive oxygen species and is also associated with immune dysfunction. We examined the efficacy of resveratrol and vitamin E on the immunomodulatory activity and vascular function in mice with liver abnormalities induced by chronic ethanol consumption by measuring the protein, liver-specific transaminase enzymes, antioxidant enzymes and non-enzymes such as reduced glutathione (GSH) content, thiobarbituric acid reactive substance (TBARS) level, nitrite level, and activities of superoxide dismutase (SOD), catalase (CAT), glutathione reductase (GR) and glutathione peroxidase (GPx) and glutathione-S-transferase (GST), and cytokines such as interleukin (IL)-2, IL-4, IL-10, tumor necrosis factor (TNF)-alpha, gamma interferon (IFN-gamma), vascular endothelial growth factor (VEGF)-A and transforming growth factor (TGF)-beta1 in mice blood. Ethanol (1.6 g/kg body wt/day) exposure for 12 wks significantly increased TBARS and nitrite levels and GST activity, and significantly decreased GSH content and the activities of SOD, CAT, GR and GPx in whole blood hemolyzate of 8-10 wks-old male BALB/c mice (weighing 20-30 g). Ethanol exposure also elevated the activities of transaminase enzymes (AST and ALT), IL-10, TNF-alpha, IFN-gamma, VEGF-A and TGF-beta1, while decreasing the albumin concentration and IL-4 activity in the serum. Both resveratrol (5 mg kg(-1) day(-1)) and vitamin E (80 mg kg(-1) day(-1)) treatment significantly reduced AST, ALT, GST, IL-10, TNF-alpha, IFN-gamma, VEGF-A and TGF-beta1 activities and levels of TBARS and nitrite, and elevated albumin content, GSH level and activities of SOD, CAT, GR and GPx, compared to ethanol-treated group. Thus, results from the study demonstrated that both resveratrol (5 mg kg(-1) day(-1)) and vitamin E (80 mg kg(-1) day(-1)) can effectively ameliorate ethanol (1.6 g kg(-1) day(-1))-induced oxidative challenges, immunomodulatory activity and angiogenesis processes.

    ABSTRACT: Alcohol consumption and health outcomes are complex and multidimensional. Ethanol (1.6g / kg body weight/ day) exposure initially affects liver function followed by renal function of 16-18 week-old male albino rats of Wistar strain weighing 200-220 g. Chronic ethanol ingestion increased in thiobarbituric acid reactive substances level and glutathione s-transferase activity; while decreased reduced gluatathione content and activities of catalase, glutathione peroxidase and glutathione reductase in a time dependent manner in the hemolysate. Though superoxide dismutase activity increased initially might be due to adaptive response, but decreased later. Elevation of serum nitrite level and transforming growth factor-b(1) activity indicated that long-term ethanol consumption may cause hepatic fibrosis and can elicit pro-angiogenic factors. However, no alteration in vascular endothelial growth factor-C activity indicated that ethanol consumption is not associated with lymphangiogenesis. Therefore, we conclude that long-term ethanol-induced toxicity is linked to an oxidative stress, which may aggravate to fibrosis and elevate pro-angiogenic factors, but not associated with lymphangiogenesis.

    ABSTRACT: Non-alcoholic fatty liver disease and its more aggressive form, non-alcoholic steatohepatitis are entities that are becoming more and more interesting to the medical community in general. A total of 93 Non-alcoholic fatty liver disease patients (64 male and 29 female) within the age range between 28 to 63 years were studied. All of them showed elevated alanine aminotransferase level (104.07 ± 56.04). Aspartate aminotransferase level (58.13 ± 31.96) was elevated more than its normal level in 82% cases and AST to ALT ratio was found 0.59 ± 0.26. Predisposing factors were diabetes mellitus (37%), obesity (13%) and hyperlipidemia (41%). In addition, 32% of the subjects were overweight.18% of the patients had elevated serum bilirubin. Our findings recommend a lower cutoff value than suggested by the World Health Organization for overweight and obesity among this racial-ethnic group.

    ABSTRACT: Alcohol consumption is implicated in the genesis of a spectrum of liver abnormalities, which are associated with a number of factors. In the present study, time-dependent effects of ethanol on cytokines (TNF-alpha, IL-2, IL-4, IL-10, IFN-gamma, VEGF-A and TGF-beta1) in serum, and blood oxidative stress parameters such as reduced glutathione content, TBARS level and activities of GPx, GR, GST, catalase and SOD in 8-10 weeks-old male BALB/c mice have been investigated. Ethanol administered @ 1.6 g/kg body wt/day significantly increased the activities of liver marker enzymes AST, ALT and ALP. Serum nitrite levels and haemolysate TBARS level also increased, while total antioxidant status in serum and GSH content in whole blood hemolysate decreased from 4th week onwards of exposure. In spite of the increased serum nitrite level and GST activity in the haemolysate, albumin level in serum, GPx and GR activities in haemolysate decreased after 12 weeks of exposure. Chronic ethanol treatment did not show any effect on IL-2, but IL-4 level was reduced and other cytokines such as IL-10, TNF-alpha, IFN-gamma, TGF-beta1 and VEGF-A levels were increased significantly after 12 weeks. The study indicates a relationship between free radical generation and immune response, and suggests that ethanol-induced liver damage is associated with oxidative stress and immunological alterations in a time-dependent manner.

    ABSTRACT: Chronic pancreatitis, an irreversible inflammatory disease of the pancreas, is associated with the replacement of the destroyed parenchyma by extended development of fibrosis. Despite marked progress in diagnostic tools, no consensus has been reached in diagnosis of chronic pancreatitis. In this study we examined the hematological and biochemical parameters among 40 chronic pancreatitis patients within 18 to 67 yrs. ESR level and ALP activity was elevated in 40% cases. Serum amylase activity increased in 32 patients and it showed significant correlation with ALP (r=0.458, p=0.003), CA-19.9 (r=0.556, p<0.001), and calcium level (r=-0.472, p=0.002). Type IV collagen level in chronic pancreatitis also elevated (164.4 ± 55.5 ng/ml) and showed negative significant correlation with calcium level (r= -0.505, p=0.001). However, no significant correlation was observed between amylase activity and type IV collagen (r=0.289, p= 0.07).

    ABSTRACT: Alcohol one of the important products of the global addiction alters brain function by interacting with multiple neurotransmitter systems, thereby disrupting the delicate balance between inhibitory and excitatory neurotransmitters. Alcohol positively reinforces drinking by producing a mild euphoria. The reinforcing effects of alcohol are mediated by several neurochemical systems and are associated with some of the behavioral manifestations of intoxication. Alcohol consumption is initially accompanied by decreased attention, alterations in memory, mood changes and drowsiness. Generally all vital functions of brain depend on a delicate balance between excitatory and inhibitory neurotransmission,which in turn dependent on short and long term alcohol consumption. Detailed understanding of alcohol's mechanism of action on the neurotransmitters of brain is a prerequisite in discovering effective treatments for both alcohol abuse and alcoholism. This review covers the elaborate literature on the subject and highlights the functions and interactions of neurotransmitters and alcoholism.

    ABSTRACT: After administration, ethanol and its metabolites go through the kidneys and are excreted into urine. The kidney seems to be the only vital organ generally spared in chronic alcoholics. Therefore, we investigated the multiple effects of chronic ethanol exposure on renal function tests and on oxidative stress related parameters in the kidney. Chronic ethanol (1.6 g ethanol/ kg body weight/ day) exposure did not show any significant change in relative weight (g/ 100g body weight) of kidneys, serum calcium level or glutathione s-transferase activity. However, urea and creatinine concentration in serum, and TBARS level in kidney elevated significantly, while reduced glutathione content and activities of glutathione peroxidase, glutathione reductase and superoxide dismutase diminished significantly after 12 weeks of ethanol exposure. Catalase activity showed increased activity after 4 weeks of ethanol exposure and decreased activity after 12 weeks of ethanol exposure. Genesis of renal ultrastructural abnormalities after 12 weeks of ethanol exposure may be important for the development of functional disturbances. This study revealed that chronic ethanol exposure for longer duration is associated with deleterious effects in the kidney.

    ABSTRACT: Damaging effects of reactive oxygen species on living systems are well documented. They include oxidative attack on vital cell constituents. Chronic ethanol administration is able to induce an oxidative stress in the central nervous system. In the present study, 16-18 week-old male albino rats of Wistar strain were exposed to different concentration of ethanol for 4 weeks. This exposure showed profound effect on body weight. Ascorbic acid level; and activities of alkaline phosphatase and aspartate transaminase in the brain are dependent on the concentration of ethanol exposure. Chronic ethanol ingestion elicits statistically significant increase in thiobarbituric acid reactive substances level and decrease in gluatathione level in the brain. It reduces superoxide dismutase, catalase, glutathione peroxidase, and glutathione reductase activities in a dose dependent manner. However, histological examination could not reveal any pathophysiological changes. Therefore, we conclude that biochemical alterations and oxidative stress related parameters respond early in alcoholism than the histopathological changes in brain.
