Abstract:
:Abnormal fluctuations of acetylcholine and serotonin might cause, or be correlated with, a variety of symptoms. This communication cites evidence which suggests that fluctuations of serotonin might have a causative role in migraine, mania, and depression and that fluctuations of acetylcholine might have a causative role in epilepsy, catalepsy, and Kleine-Levin attacks.

杂志文章abstract::Parathyroid hormone (PTH) acts as a controller of bone remodeling and has influence on periodontal tissues. In addition to the well-established catabolic effects (activation of bone resorption) of PTH, it is recognized that the PTH intermittent administration has anabolic effects (promotion of bone formation). However...
