Twelve animal models of depression related to some sets of validating criteria are reviewed. Of the 12 models, some traditional models (reserpine reversal, amphetamine potentiation) are rejected as they are devoid of selectivity, insufficient to predict antidepressant activity in the compounds tested. The models with the highest overall validity are the intracranial self-stimulation, chronic stress and learned helplessness models in rats, and the primate separation model. A combination of several models may be the best way to study depression and to screen antidepressant drugs. This combination can be used to detect compounds comparable to those antidepressants possessing clinically established antidepressant activity.展开更多

There are many studies on it, such as inflammation, autoimmune disease, xenotransplantation, anti-tumor, etc. CVF is also an important tool drug for the study of complement role in the pathophysiological development of diseases.展开更多
