[ 1 ] - The Effect of Protocatechuic Acid on Blood Pressure and Oxidative Stress in Glucocorticoid-induced Hypertension in Rat

Oxidative stress is one of the important mechanisms involved in Dexamethasone (Dex)-induced hypertension. Protocatechuic acid (PCA) is a natural compound with high antioxidant capacity. In this investigation, the effect of pretreatment with PCA was studied in Dex-induced hypertensive male Wistar rats. For induction of hypertension, Dex was injected subcutaneously for 14 days. PCA (50, 100 and 2...

[ 2 ] - Anti-inflammatory Effect of Amitriptyline on Ulcerative Colitis in Normal and Reserpine-Induced Depressed Rats

Depressive disorders are more common among persons with chronic diseases such as inflammatory bowel disease and anti-inflammatory effect of some antidepressants such as amitriptyline has been reported. Acetic acid colitis was induced in both reserpinised (depressed) and non-reserpinised (normal) rats. Reserpinised groups received reserpine (6 mg/kg, i.p.) one hour prior to colitis induction. Th...

[ 5 ] - In vitro and in vivo interaction of oral contraceptive high dose (HD) with urine morphine diagnostic test

Introduction: Urine morphine test, in several countries is the most primarily available qualitative test for detecting opioid abusers. Since the users of illicit drugs attempt to defeat urine tests and there are also plenty of claims that usage of HD (high dose) contraceptive pills can result in false-negative results, we decided to design the present study to investigate the probable in vit...
