Effect of diplodiatoxin (Stenocarpella maydis) on some enzymatic profiles in male and female rats.

| Abstract |
Acute and subacute effects of diplodiatoxin were monitored with special reference to biochemical target enzymes like acid phosphatase (AcP), alkaline phosphatase (AkP), and acetylcholinesterase (AChE) in male and female rats. For acute toxicity study the rats were treated with single oral dose of 5.7 mg/kg of diplodiatoxin, whereas for subacute toxicity study the rats were orally treated with 0.27 mg/kg/day for 21 days. Diplodiatoxin caused loss in body weight and feed intake with other clinical symptoms. Due to the acute and subacute treatment of diplodiatoxin significant decreases were observed in serum AcP and AkP and also in liver AkP, whereas liver AcP increased in both male and female treated rats. Further, significant inhibition of brain AChE was observed in acute and subacute treated animals, indicating its effect on nerve synapsis. Sexual dimorphism was recorded when the activity of male rats was compared with female rats. The values were near those of controls on Day 7 (posttreatment), indicating recovery in the altered enzymes once the treatment was ceased. These results suggest that diplodiatoxin is toxic and has potential to affect the normal functioning of individuals and can cause changes in vital tissues such as liver.
