Background: Inflammation and oxidative stress are common in patients with chronic renal disease, including hemodialysis patients. The present study was designed to investigate the effects of L-carnitine supplements on inflammatory cytokines, CRP and oxidative stress in hemodialysis patients. Materials and methods: The study was a randomized clinical trial. Thirty-six hemodialysis patients, (2...
The plasma carnitine concentration regulates renal OCTN2 expression and carnitine transport in rats.
Previous findings in rats and in human vegetarians suggest that the plasma carnitine concentration and/or carnitine ingestion may influence the renal reabsorption of carnitine. We tested this hypothesis in rats with secondary carnitine deficiency following treatment with N-trimethyl-hydrazine-3-propionate (THP) for 2 weeks and rats treated with excess L-carnitine for 2 weeks. Compared to untrea...
Background: The benefit effect of L-carnitine is proposed for treatment of obesity as long time periods. So, in the present study, effect of L-carnitine on serum FSH, LH and testosterone levels in adult male rats is evaluated. Materials and Methods: Rats were treated different doses of L-carnitine tartarate daily for 16 days, peritoneally. The control group was treated saline as vehicle. After ...
Aim: We measured carnitine levels in patients with carnitine including dialysis patients, and examined whether administration of L-carnitine improved muscle symptoms. Methods: We measured carnitine levels in 27 patients with liver cirrhosis who were receiving treatment in our hospital, and administered L-carnitine (600 mg 1800 mg) to patients having muscle cramps for approximately one month and...
carnitine is a water-soluble quaternary amine which increases the long-chain fatty acid metabolism by facilitation of their transport to the oxidation site (mitochondria). carnitine most likely is present in all animal species, in many microorganisms, and in many plants. in this study, we determined the carnitine level of sera in pregnant and non-pregnant women by segade modified method. averag...
The effect of short- and long-term feeding with L-carnitine, L-acetyl carnitine and L-propionyl carnitine on the production of eicosanoids from in vitro stimulated carrageenan-induced rat peritoneal macrophages was investigated. Both young (4 weeks) and old (18 months) rats were used. A lower number of cells was isolated from the peritonea of treated than control young rats after 4 d feeding, b...
Acetylation of added (-)carnitine by heart mitochondira coupled to the oxidation of pyruvate in the presence of malonate was inhibited, apparently competitively, by long chain acyl(+)carnitines although the activity of carnitine acetyltransferase (EC 2.3.1.7) itself was not affected. Mitochondria have been found to possess a translocase system that allows the transport of carnitine and acylcarn...
Carnitine has a critical role in energy metabolism. Many of the functions of carnitine are not clearly elucidated and many of the regulatory mechanisms governing carnitine metabolism are ill-defined. Carnitine deficiency can be life threatening but may be resolved with carnitine supplementation. Various groups of individuals in addition to those with the classical carnitine deficiency syndrome ...
Introduction: This study aimed to compare the response of liver tissue BAX and BCL-2 gene expression to aerobic training with L-carnitine supplementation in rats intoxicated by Boldenone. Material and Methods: In this experimental study, 30 male Wistar rats, aged 12 weeks (weight 195±7.94 g) were randomly divided into five groups: control, no-treatment, boldenone (5 mg/kg), L-carnitine (100 mg...
L-carnitine and acetyl-L-carnitine (ALC) are both used to improve mitochondrial function. Although it has been argued that ALC is better than l-carnitine in absorption and activity, there has been no experiment to compare the two compounds at the same dose. In the present experiment, the effects of ALC and L-carnitine on the levels of free, acyl, and total L-carnitine in plasma and brain, rat a...
