THE EFFECT OF ALKALINE (BASES) EXTRACT FROM KHAT PLANT ON CELLS

Auther : Dr. Ahmed Mohamed Kabarity and Ganima Malallah

 

         The khat extract showed a mitodepressive effect on the rate of cell division in Allium cepa root tips.  This effect increased as the time of exposure increased till it reached a maximum of complete inhibition of cell division after exposure.

           In the short treatment time of Khat extract, the root tips showed a slight increase in the mitotic index after a period of recovery in water.  The increase was greater with a more extended time of recovery enough to bring back the cell division.  The longer the exposure, the longer the recovery time needed.

           The harmful effect of khat on the rate of cell division of Allium cepa root tips caused an imbalance in the frequencies of mitotic phases.
