Subject: Dinh Lang Extends Lifespan (fwd)

     If anyone on cryonet has any positive information on the commercial 
availability of dinh lang extract please communicate this to myself at 

     Alcoholic extracts from the Vietnamese herb dinh lang has been proven
 to be effective in extending rodent maximum lifespan.
     Here's some data. 
     Dinh lang extract and deprenyl have some additive effects on
 prolonging the lifespan of OFA-1 mice. (Acta Physiologica Hungarica
 79(2): 119-124 1992)

 control     133 weeks
 dinh lang   170
 deprenyl    162
 both        180

     This also works in Wistar rats as well. (Acta Physiologica Hungarica
 75: 301-302 1990)

 control      147     164 weeks
 dinh lang    180     194
 dinh lang &  206     239

     The life extending effect of dinh lang extract appears to be quite
 real as it has been demonstrated in two strains of rodents. Moreover dinh
 lang appears to be more effective than deprenyl. 
     In addition the dosage used was probably suboptimal. Only 10 mg/kg
 extract was used in the life extension experiments, while maximal effects
 of passive avoidance performance in young OFA mice was found at 20 mg/kg. 
 (Acta Physiologica Hungarica 75(1): 69-76 1990) In Wistar rats aged 22-24
 months 20.8% resumed full scale sexual activity at a dosage of 20 mg/kg,
 11.5% at 10 mg/kg, 7.7% at 5 mg/kg and 0% for controls. (Acta
 Physiologica Hungarica 75(1): 61-67 1990)
     It would be interesting to see more research on dinh lang, especially
 at the 20 mg/kg dosage.
