INTRODUCTION: Research suggests that there are three interrelated, yet distinct, emotion-motivation brain systems for human love (lust, romantic love, and attachment), each associated with a unique catecholaminergic and hormonal profile. Of interest for the current study are norepinephrine (NE) and dopamine (DA), which have a hypothesized connection with romantic love. As NE and DA are also known to facilitate sexual arousal, it is plausible that NE and DA may have a greater positive association with the sexual arousal responses of women in romantic love compared with women in lust.

The present study was undertaken to evaluate the effects of single and repeated doses of triazolam (1 mg/kg IP) and desipramine (DMI) (10 mg/kg IP) alone and in combination on certain pharmacologic responses and brain catecholamine levels in rats.

Acute physical restraint represents a potent stressor in several animal species and is accompanied by a complex pattern of hormonal responses and functional changes in the central nervous system. Repeated immobilization leads to partial blunting of the behavioral and hormonal responses, with transient modifications of neurotransmitter systems in the brain.

In this study, 16 patients matched with 16 controls were hypnotized prior to angioplasty. The hypnotized patients had a 25% increase in the time the cardiologist was able to keep the balloon inflated compared to the controls. Of the hypnotized patients, 13% required additional narcotic pain medication during the procedure as compared to 44% for the controls.

In a number of studies it has been shown that psychological factors in general and specifically emotional factors can be correlated to changes in immunological function and defence mechanisms. Although the mediating pathways between the central nervous system and the immune system still remain unclear, it is known that some of the 'classical stress hormones' such as cortisol and catecholamines have modulatory effects on different immunological parameters.

Erythromelalgia is an unusual condition characterized by attacks of burning pain in the hands and feet with local congestion and increased skin temperature. We report a case of erythromelalgia, with transient hypertension and elevated urinary catecholamines successfully treated by hypnotherapy. Such an association has not to our knowledge been previously reported in English language publications.

Pharmacological and metabolic effects of ashwagandha (Withania somnifera L. (Solanaceae)) used in Ayurveda as a herbal tonic and health food were studied. Ashwagandha was shown to increase swimming time in rats in physical working capacity test, i.e. rats swimming endurance test. Significant increase in relative heart weight and glycogen content in myocardium and liver was also observed in ashwagandha treated group. Ashwagandha treatment increased the duration of contractility in functional test for the resistance of frog heart muscle towards the toxic action of strophanthin-K.

ETHNOPHARMACOLOGICAL RELEVANCE: Valeriana wallichii DC, an ayurvedic traditional medicine has now been shown to exist chemically as three distinct chemotypes. The study aimed to investigate the antidepressant effect of dichloromethane extract of Valeriana wallichii patchouli alcohol chemotype. MATERIALS AND METHODS: Antidepressant effect of dichloromethane extract of Valeriana wallichii (10, 20 and 40mg/kg, p.o.) using forced swim test, was determined in both acute and chronic study. The neurotransmitter levels were estimated in mouse forebrain after two weeks of dosing.
