Induced Contractions in Rat Vascular Smooth Muscle

چکیده
Using front-surface fluorometry, we determined the effects of cocaine on force and cytosolic Ca2' concentration ([Ca2+] ) in the rat aorta. We also examined the effects of cocaine on 45Ca2` influx. Cocaine (10-` to 10` M) alone did not alter the resting level of [Ca2`], and force. Cocaine (<l0-` M), in a concentration-dependent manner, potentiated the 10-6 M serotonin (5-HT)-induced or 10` M norepi-

The role of autophagy in advanced glycation end product-induced proliferation and migration in rat vascular smooth muscle cells
Objective(s): To investigate the role of autophagy in advanced glycation end products (AGEs)-induced proliferation and migration in rat vascular smooth muscle cells (VSMCs).Materials and Methods: After culture, VSMCs were treated with 0, 1, 10, and 100 μg/ml concentrations of AGEs. Autophagy specific protein light chain 3 (LC3)-I/II was determined by western blotting, autophagosomes were observ...
متن کاملGestational hypothyroidism-induced changes in L-type calcium channels of rat aorta smooth muscle and their impact on the responses to vasoconstrictors
Objective(s): Thyroid hormones play an essential role in fetal growth and maternal hypo-thyroidism which leads to cardiovascular deficiency in their offspring. Considering this, we intended to investigate the impact of gestational hypothyroidism on offspring vascular contractibility and possible underlying mechanisms. Materials and Methods: Hypothyroidism was induced in female rats by administ...
متن کاملCalcium Antagonistic Activity of Biophytum Petersianum on Vascular Smooth Muscles of Wistar Rat
The whole plant of Biophytum petersianum was extracted with a mixture of water – alcohol (1:1) to evaluate its relaxant effect on aorta rings. In isolated Wistar rat tissue, the hydro-ethanolic extract (0.1; 0.25 and 0.5 mg/ml) non-competitively antagonized calcium chloride and high-K + - induced aorta contractions in a concentration-dependent manner. Moreover, the inhibition of noradr...
متن کاملThe effect of adrenomedullin and proadrenomedullin N- terminal 20 peptide on angiotensin II induced vascular smooth muscle cell proliferation
Objective(s): The study aimed to investigate the effects of adrenomedullin (ADM) and proadrenomedullin N- terminal 20 peptide (PAMP) on angiotensin II (AngII)-stimulated proliferation in vascular smooth muscle cells (VSMCs). Materials and Methods: Thoracic aorta was obtained from Wistar rats and VSMCs were isolated from aorta tissues and then cultured. In vitro cultured VSMCs were stimulated w...
متن کاملThe Relaxant Effect of Crocin on Rat Tracheal Smooth Muscle and Its Possible Mechanisms
Crocin, a component of saffron, showed hypotensive which is perhaps due to vascular smooth muscle relaxant effect. The relaxant effects of saffron on tracheal smooth muscle also could be due to its constituent, crocin. In the present study, the relaxant effects of crocin and its possible mechanisms on rat tracheal smooth muscle were investigated. The relaxant effects of three cumulative concent...
متن کاملProstaglandins and potassium relaxation in vascular smooth muscle of the rat. The role of Na-K ATPase.
We explored the hypothesis that postaglandin-induced vasodilation is caused by activation of the electrogenic sodium-potassium pump which results in membrane hyperpolarization and relaxation of vascular smooth muscle. Helical strips of rat tail artery relax in response to potassium after norepinephrine-induced contractions in physiological salt solution containing a low-potassium concentration....
