title: Jobelyn® pretreatment ameliorates symptoms of psychosis in experimental models.
abstract: BACKGROUND
  Psychosis is a chronic neurological disorder and it remains a major medical and social problem in most African countries. Individuals with psychotic illness in this region tend to seek help from traditional medical practitioners, who prescribe herbal remedies as alternative forms of treatment for the disease. Jobelyn® (JB) is a commercial polyherbal formulation that has been acclaimed to show beneficial effects in neurological disorders. However, its usefulness in psychosis has not been scientifically validated. Thus, this study was undertaken to evaluate its effects on animal models predictive of human psychosis.
  
  
  METHODS
  Antipsychotic activity of JB was assessed based on the inhibition of stereotyped behavior induced by amphetamine or apomorphine in mice. Amphetamine-induced hyperactivity and lethality in aggregated mice were additional tests employed to further evaluate the antipsychotic property of JB. The effect of JB on catalepsy was also assessed, using the inclined plane paradigm.
  
  
  RESULTS
  JB (5-50 mg/kg, p.o.) significantly (p<0.05) inhibited stereotypy induced by amphetamine (10.0 mg/kg, i.p.) or apomorphine (1 mg/kg, i.p.), which suggests antipsychotic activity. Furthermore, JB (5-50 mg/kg, p.o.) reduced lethality in aggregated mice and inhibited hyperactivity induced by amphetamine, respectively. However, JB (5-50 mg/kg, p.o.) did not cause cataleptic behavior, as it failed to alter the duration of stay of the animals on the inclined plane.
  
  
  CONCLUSIONS
  Taken together, these findings suggest that JB exhibits antipsychotic-like activity, devoid of the adverse effect of cataleptic behavior, and may offer some beneficial effects in the symptomatic relief of psychotic ailments.
