Background/aim: Cisplatin (CIS) is an effective antineoplastic agent used in the treatment of several cancer types. Peripheral neuropathy is a major dose-limiting side-effect in CIS therapy. Cannabinoids may alleviate this painful side effect. This study investigated the analgesic effects of anandamide (AN) on CIS-induced peripheral neuropathy, in...

Background: Chemerin is a novel chemoattractant adipokine, expressed in cardiovascular system and its receptor has also been detected in epicardial adipose tissue. Aims: The objective of this research is to determine the effects of chemerin on the cardiac parameters and gene expressions, in isolated perfused rat heart. Study design: Animal exp...
Article
Objective: Statins, or 3-hydroxyl-3-methylglutaryl-coenzyme A (HMG-CoA) reductase inhibitors, which are potent inhibitors of cholesterol synthesis, are widely used in the treatment of hypercholesterolaemia and prevention of coronary artery diseases. Evidence from clinical trials also show other beneficial actions of statins unrelated to their chole...

Cisplatin is a widely used antineoplastic agent in the treatment of various cancers. Peripheral neuropathy is a well‐known side effect of cisplatin and has potential to result in limiting and/or reducing the dose, decreasing the quality of life. Thus, effective treatments are needed. Agmatine is an endogenous neuromodulator that has been shown to e...

Pregabalin, a drug used in epilepsy, anxiety, neuropathic pain is reported to have analgesic effects in inflammatory pain. We aimed to investigate whether pregabalin have gastric side effects and to compare with a non steroidal antiinflammatory drug (NSAID) in rats. The effects of pregabalin on antioxidant levels, which are suggested to protect aga...

Background: Cisplatin (CIS) is an effective antineoplastic agent used in treatment of several cancer types. However, peripheral neuropathy is a major side-effect seen in most of patients. Cannabinoids are known to have a potential analgesic effect. The aim was to investigate the antinociceptive effects of chronic administration of anandamide (AN),...
Article
Full-text available
Objective: It was suggested that prostaglandins which are synthesized by cyclooxygenase (COX) enzymes contribute to the actions of angiotensin-converting enzyme (ACE) inhibition and angiotensin AT1 receptor antagonism and there is an interaction between ACE signaling pathway and COX enzymes. We aim to investigate the role of COX enzymes in the effe...

Resveratrol (RES), a polyphenolic compound, was reported to have protective effect against convulsions. The effects of resveratrol alone or in combination with low-dose antiepileptics against pentylenetetrazole (PTZ)-induced seizures and its histological effects in brain regions were investigated. Mice were divided into 8 groups: Control, RES (75m...
Article

Background: Calcium homeostasis is considered to be important in antineoplastic as well as in neurotoxic adverse effects of cisplatin. Aims: This study aimed to investigate the role of Ca2+ in cisplatin neurotoxicity in cultured rat dorsal root ganglia (DRG) cells. Study Design: Cell culture study. Methods: DRG cells prepared from 1-day old Sp...

We aimed to investigate the effects and mechanisms of action of p-nonylphenol(p-NP) on uterine contractility in rats. The uterine tissues of female Sprague Dawley rats in diestrus were bathed in isolated organ bath. The effects of vehicle alone (0.1% ethanol), the positive control 17-β-E2 (10(-5) M) and p-NP (10(-9) M, 10(-8) M, 10(-7) M, 10(-6) M)...
