Background: The Bipolar Disorder Patients Follow-up (BDPF) project is a longitudinal, prospective and naturalistic study. The purpose of the present report is to introduce the project, elaborate its methods, and present the reliability data of the utilized symptoms rating scales. Methods: The sampling started in May 2008 and is still in progress. The probands are assessed at the beginning of the sampling and then 2 and 6 months later and then every 6 months using several instruments to identify psychiatric comorbidities, symptoms severity, quality of life, attempted suicide rate, treatment compliance, and some other factors. Results: The results could lead to increase the clinicians′ awareness about the clinical picture of this disorder in Iranian patients. Conclusions: The present project could decrease to some extent the current shortcomings in Iran′s psychiatric data at least about one of the major psychiatric disorders known as the eighth result which cause medical disability over the world.

Objective(s): Studies indicate that major deficiency in the levels of monoaminergic transmitters is a reason for severe depression. On the other hand, it is shown that Carthamus tinctorius L. (CT) may improve neuropsychological injuries by regulation of the monoamine transporter action. Hence, the present study was undertaken to evaluate the involvement of monoaminergic systems in antidepressant-like effect of CT extract in the tail suspension test (TST) in mice. Materials and Methods: The mice were intraperitoneally (IP) treated with CT extract (100–400 mg/kg) 1 hr before the TST. To investigate the involvement of monoaminergic systems in antidepressant-like effect, the mice were treated with receptor antagonists 15 min before CT extract treatment (400 mg/kg, IP) and 1 hr before the TST. Results: Findings showed that CT extract (100–400 mg/kg, IP), dose-dependently induced antidepressant-like effect (P
