Syndrome type psychomotor retardation

The antidepressant activity of hypericum has been extensively investigated over the last two decades in animal models (forced-swimming and tail-suspension tests) as well as in humans. Clinical trials have demonstrated an improvement in symptoms of anxiety, dysphoric mood, hypersomnia, anorexia, depression, insomnia, psychomotor retardation, and other subjective indicators.Potential for the treatment of premenstrual syndrome (PMS) also exists. Earlier studies also showed that hypericum enhanced mice exploratory activity in a foreign environment, extended narcotic sleeping time (dose dependent), is a reserpine antagonist, and decreased aggression in socially isolated male mice. Hypericin has been found to inhibit in vitro almost irreversibly both type A and B monoamine oxidase (MAO) in rat brain mitochondria. Type A MAO (serotonin) inhibition was more pronounced, but with long-term use (8 weeks of daily treatment). Other mechanisms of action, such as serotonin transport and up-...
