methanol extract of dried leaves of momordica charantia linn ( cucurbitaceae ) was investigated for anxiolytic, antidepressant and anti-inflammatory activities in animal models. anxiolytic activity of methanol extract of dried leaves of momordica charantia linn was tested by elevated plus maze test and the results showed a significant anxiolytic effect comparable, with diazepam in all the teste...

introduction: celastrus paniculatus seed oil, commonly known as malkangni or jyotishmati, was in use from time immemorial to treat brain related disorders. celastrus paniculatus seed oil has significant antidepressant-like activity in chronic unpredictable stressed mice. the present study was undertaken to evaluate the antidepressant-like effect of celastrus paniculatus seed oil in unstressed m...

A wide diversity of animal models has been used to examine antidepressant activity. These range from relatively simple models sensitive to acute treatment, to highly sophisticated models that reputedly model some aspect of depressive illness and which yield a positive response to prolonged, chronic, drug treatment. In recent years antidepressant drug research has focused on the search for antid...

OBJECTIVE Tachyphylaxis often refers to the loss of antidepressant efficacy during long-term treatment.
