Protective effect of betaine against skeleton muscle apoptosis in rats induced by chronic alcohol and statin consumption

AIM: The aim of the present study was to investigate the effect of apoptosis on rat skeletal muscle caused by chronic alcohol and statin consumption with modified liquid diet and to elucidate protective effects of betaine supplementation.METHODS: TNF-alpha (tumor necrosis factor), NF-kappa B (Nuclear Factor kappa B), cytochrome c and caspase-3 levels with or without betaine treatment in alcohol and/or statin-induced skeleton muscle apoptosis rats as well as in controls were measured in serum and tissue. Histologic examinations of the muscle tissues were also performed.RESULTS: In our study, betaine treated treatment groups we found that calpain and caspase activities and cytokine c release were decreased caused by alcohol, statin and more importantly alcohol+statin group and TNF and NF-kappa B levels were also close to the levels of control group. Similarly, significant improvements have been observed in our morphological and histological examination results also supporting our biochemical data.CONCLUSION: We found that combined consumption of ethanol and statin is capable of triggering apoptotic cell death in rat muscles more than the consumption of only alcohol or only statin. Betaine was able to reduced this muscle cell death induced by alcohol and/or statin consumption

The investigation of the prenatal and postnatal alcohol exposure-induced neurodegeneration in rat brain: protection by betaine and/or omega-3

We aim to study the effect of neurodegeneration on the brain of rat pups caused by prenatal and postnatal ethanol exposure with modified liquid diet to elucidate protective effects of betaine and omega-3 supplementation. When ethanol is consumed during prenatal and postnatal periods, it may result in fetal alcohol syndrome (FAS) in the offspring

Effect of kefir and low-dose aspirin on arterial blood pressure measurements and renal apoptosis in unhypertensive rats with 4 weeks salt diet

We aim to study the effect of low-dose aspirin and kefir on arterial blood pressure measurements and renal apoptosis in unhypertensive rats with 4 weeks salt diet. Forty adult male Sprague-Dawley rats were divided into five groups: control, high-salt (HS) (8.0% NaCl), HS + aspirin (10 mg/kg), HS + kefir (10.0% w/v), HS + aspirin + kefir. We measured sistolic blood pressure (SBP), mean arterial pressure (MAP), diastolic pressure, pulse pressure in the rats. Cathepsin B, L, DNA fragmentation and caspase-3 activities were determined from rat kidney tissues and rats clearance of creatinine calculated. Although HS diet increased significantly SBP, MAP, diastolic pressure, pulse pressure parameters compared the control values. They were not as high as accepted hypertension levels. When compared to HS groups, kefir groups significantly decrease Cathepsin B and DNA fragmentation levels. Caspase levels were elevated slightly in other groups according to control group. While, we also found that creatinine clearance was higher in HS + kefir and HS + low-dose aspirin than HS group. Thus, using low-dose aspirin had been approximately decreased of renal function damage. Kefir decreased renal function damage playing as Angiotensin-converting enzyme inhibitor. But, low-dose aspirin together with kefir worsened rat renal function damage. Cathepsin B might play role both apoptosis and prorenin-processing enzyme. But not caspase pathway may be involved in the present HS diet induced apoptosis. In conclusion, kefir and low-dose aspirin used independently protect renal function and renal damage induced by HS diet in rats

Effect of boric acid on oxidative stress in rats with fetal alcohol syndrome

To the best of our knowledge, this is the first study concerning the effect of boric acid (BA) administration on fetal alcohol syndrome (FAS). In this study, the aim was to investigate prenatal alcohol-induced oxidative stress on the cerebral cortex of newborn rat pups and assess the protective and beneficial effects of BA supplementation on rats with FAS. Pregnant rats were divided into three groups, namely the control, alcohol and alcohol + boric acid groups. As markers of alcohol-induced oxidative stress in the cerebral cortex of the newborn pups, malondialdehyde (MDA), superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx) levels were measured. Although the MDA levels in the alcohol group were significantly increased compared with those in the control group (P<0.05), the MDA level in the alcohol + boric acid group was shown to be significantly decreased compared with that in the alcohol group (P<0.01). The CAT activity of the alcohol + boric acid group was significantly higher than that in the alcohol group (P<0.05). The GPx activity in the alcohol group was decreased compared with that in the control group (P<0.05). These results demonstrate that alcohol is capable of triggering damage to membranes of the cerebral cortex of rat pups and BA could be influential in antioxidant mechanisms against oxidative stress resulting from prenatal alcohol exposure

Effect of chronic alcohol consumption on myocardial apoptosis in the rat model of isoproterenol-induced myocardial injury and investigation on the cardioprotective role of calpain inhibitor 1

We investigated the presence of myocardial apoptosis on isoproterenol (ISO)-induced myocardial injury (MI) after long-term high dose alcohol consumption and examined the antiapoptotic role of calpain inhibitor 1. Male Wistar Albino rats (n = 108) were divided into six groups: Control, alcohol (ethanol was given during 30 days for chronic alcohol consumption), MI (150 mg/kg ISO injection at last two days of alcohol consumption), alcohol + MI, alcohol + MI + calpain inhibitor 1 (10 mg/kg inhibitor was injected at 15 min before ISO injections) and Dimethyl Sulfoxide (DMSO) groups. Biochemical, histological, and morphometric methods determined apoptosis levels in the heart tissue of rats. Cytochrome c, caspase 3, and calpain levels were significantly high in alcohol, MI, and alcohol + MI groups. In contrast, mitochondrial cardiolipin content was found to be low in alcohol, MI, and alcohol + MI groups. These parameters were close to the control group in the therapy group. Histological and morphometric data have supported biochemical results. As a result of our biochemical data, myocardial apoptosis was seen in the alcohol, MI, and especially alcohol after MI groups. Calpain inhibitor 1 reduced apoptotic cell death and prevented myocardial tissue injury in these groups. The efficiency of calpain inhibitor was very marked in MI after long-term high dose alcohol consumption

Boric acid supplementation can prevent oxidative damage caused by prenatal alcohol exposure in rat cerebral cortex

İstanbul Bilim Üniversitesi, Sağlık Hizmetleri Meslek Yüksekokulu.Depending on its acute or chronic usage and the dosage, alcohol has toxic effects on both mother and fetus when it is administered during pregnancy 1. Up till now, fetal alcohol spectrum disorders (FASD) has been shown to include alcohol-related birth defects (ARBD), alcohol-related neurological disorders (ARND) and fetal alcohol syndrome (FAS). Children born with FAS have some difficulties in learning, memory, attention span, communication, hearing and vision. In order to overcome this problem, new strategies should be developed to prevent the teratogenic effects of alcohol on fetus. Oxidative stress has been shown to be related to many diseases including FAS 2. Oxidative stress leads to increasing lipid peroxidation and reactive oxygen species (ROS) formation that results in malfunction of the enzymes and membrane disruption 3. Antioxidants such as superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx) have role in ROS detoxification

Paraoxonase1 192 (PON1 192) Gene Polymorphism and Serum Paraoxonase Activity in Panic Disorder Patients

Background/Aim: Reactive oxygen species (ROS) are involved in the development of certain neuropsychiatric disorders. Paraoxonase 1 (PON1) activity has been suggested to be adversely related to oxidative stress in plasma. The purpose of the present study was to demonstrate the relationship between serum PON1 activity and PON1 192 polymorphism in panic disorder (PD). Materials and Methods: Fourty-two patients with PD and 46 healthy controls were included in this study. PON1 192 genotypes were determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis. PON1 activity was measured by spectrophotometric assay of p-nitrophenol production following the addition of paraoxon. Results: PON1 192 AA genotype and A allele in PD were significantly higher than in the control group, whereas the B allele was found to be significantly higher in the control group. Patients with panic disorder have lower PON1 activity than the control group. Conclusion: The PON1 192 AA genotype may increase the risk of PD depending on lipid peroxidation
