The hypothesis that atherosclerotic processes are mostly caused by immune (autoimmune) mechanisms has recently been gaining attraction. At the same time, autoimmune of atherogenesis not become generally accepted and requires additional evidence. Previously, we were able to induce changes in aortic wall similar those observed early stages human atherosclerosis, also produce visceral obesity norm...
The pharmacological properties and mechanism of the action of protopine on isolated rat thoracic aorta were examined. It inhibited norepinephrine (NE, 3 microM)-induced tonic contraction in rat thoracic aorta in a concentration-dependent manner (25-100 micrograms/ml). The phasic contraction caused by NE was inhibited only by a high concentration of protopine (100 micrograms/ml). At the plateau ...
Objective: Diabetes is an important risk factor for cardiovascular events. The great percent of morbidity in patients with diabetes is due to endothelial dysfunction. The present study investigated the effects of hydroalcholic extract of Nigella sativa (N. sativa) on contractile and dilatation response of isolated aorta in streptozotocin (STZ)-induced diabetic rat. Materials and Methods: Rats ...
The Effects of L-Citrulline Pretreatment on the Isometric Tension of the Isolated Perfused Rat Aorta
Background: The achievement of an effective compound for prevention/treatment of hypertension with fewer complications has been of interest in recent years. OBJECTIVES: This study aimed to examine the effects of L-citrulline pretreatment on the tension of isolated rat aortic tissues precontracted by different vasoconstrictors. METHODS: Sixteen male Wistar rats (300-350g) were randomly divided i...
