Effects of milrinone on contractile responses of guinea pig trachea, lung parenchyma and pulmonary artery.
The effects of milrinone, a bipyridine with known vasodilator activity, on guinea pig tracheal-spirals, lung parenchymal strips and pulmonary artery rings in vitro were compared with the effects of isoproterenol and aminophylline on these tissues. The concentration of milrinone that produced 50% relaxation (IC50) of tracheal spirals constricted by carbachol was 3.6 X 10(-5) M. Isoproterenol (IC...
متن کاملComparative distribution of smooth muscle postsynaptic contractile responses in canine trachea and bronchus in vivo.
The response of canine tracheal and bronchial smooth muscle to i.a. administered agonists causing smooth muscle contraction was compared in 22 mongrel dogs in vivo. Tracheal and bronchial contractile responses were measured isometrically in situ in the same dogs. In nine dogs, dose-response curves were generated with i.a. acetylcholine and histamine (10(-10) to 10(-6) mol) in a 4-cm tracheal se...

متن کاملEffects of trichloroethylene and perchloroethylene on muscle contractile responses and epithelial prostaglandin release and acetylcholinesterase activity in swine trachea.
Trichloroethylene (TCE) and perchloroethylene (PERC) have been reported to induce respiratory complications such as airway hyperactivity and asthma. The present study was designed to investigate their influence on smooth muscle contraction and epithelial release of prostanoids in swine trachea. Results showed that TCE and PERC exposure did not alter the basal tone of tracheal smooth muscle. How...
متن کاملContractile responses of the rat gastrocnemius and soleus muscles to isotonic resistance exercise.
Male rats were divided into control and weight-trained (WT) groups. WT rats performed squat-type exercises twice daily, 5 days/wk, for 14 wk. They averaged 36 lifts/day, with an average weight of 555 g. Muscle-to-body weight ratio (mg/g) of the soleus (Sol) was not different from control, but it increased 11 and 6% in the gastrocnemius (Gast) and plantaris, respectively (P < 0.05). The normaliz...
