[Muscle action potential and masticatory rhythm of anterior temporal and masseter muscles in children and adults].

For the investigation of the functional change of the masticatory muscles along with growth and development, electromyographic evaluation was carried out. The subjects were 6 children (5 males and 1 female) with full deciduous dentition (Hellman's dental age IIA) aged 4.5 +/- 0.

[Frequency analysis of the EMG power spectrum of the anterior temporal and masseter muscles in children and adults].

For the investigation of the functional change of the masticatory muscles along with growth and development, the frequency analysis of the EMG power spectrum was carried out. The subjects were 6 children (5 males and 1 female) with full deciduous dentition (Hellman's dental age IIA) aged 4.5 +/- 0.

[Pharmacological studies of MO-8282, a new antidepressant].

We investigated the pharmacological characteristics of MO-8282 as a novel antidepressant. MO-8282 inhibited the specific binding of 3H-clonidine to cerebro-cortical membrane fractions from rats about five times more potently than mianserin, and it competed with clonidine in the twitch response of the isolated guinea-pig ileum under field stimulation. The results indicated that MO-8282 possessed alpha 2-adrenergic receptor blocking activity.
