Differential effect of a polyherbal formulation-OB-200G in male and female mice subjected to forced swim stress.
The antistress effect of a polyherbal formulation-OB-200G (500 mg/kg. p.o.) was studied in both male and female mice subjected to forced swim stress. Fluoxetine (10 mg/kg, i.p.) was chosen as standard drug for comparison. Exposure of mice to chronic stress regime resulted in decreased body weight in both male and female mice, increased sweetened food intake, anxiety, depression and locomotor activity in stressed female mice as compared to unstressed control (normal) mice. Treatment with OB-200G resulted in a further decrease in body weight, increased food intake and locomotor activity in both stressed male and female mice. It also reduced immobility time, decreased latency to enter and increased number of entries and time spent in mirror chamber in stressed female mice. Administration of fluoxetine (10 mg/kg, i.p.) decreased body weight and food intake in both stressed male and female mice. Fluoxetine treatment also increased time spent in mirror chamber and decreased immobility time in stressed female mice. Thus, like fluoxetine, OB-200G decreased body weight and produced antianxiety and antidepressant effects in stressed female mice and may prove beneficial in obese patients reported to be more susceptible to stress-related psychological disorders.
