introduction: motor behavior and coordination impairment are known side effects of opioid treatment, yet very few studies have investigated the effects of tramadol on motor behavior, or compared its effect with the effect of an opioid. this study investigates the effects of chronic injection of morphine and tramadol on rat motor function during infancy. methods: neonate rats (n=56) were randoml...

A more serious handicap must be the limitation of my experience to that minor part of the world with a problem of food surplus rather than scar...
