Day-night treatment difference of tobramycin serum and intrarenal drug distribution and nephrotoxicity in rats: effects of fasting.

abstract：:The pineal hormone melatonin is potentially useful in the treatment of disorders, especially sleep disorders, associated with circadian rhythm disturbance. We have examined its effects on sleep, mood, and behaviour in a double-blind, placebo-controlled study of a small group of police officers working spans of seven s...
