The results demonstrated that 1/3 of RA cells had a special structure: there were 1 to 2 "vegetation" connected with the bacteria, and could drop from the bacteria.

Conclusion PS-1 mutant L286V plays a role in inhibiting the growth and accelerating the apoptosis of RA-induced PC12 cells.

AIM: to observe the influences of radix astragali (ra) against the apoptosis of nerve cells, so as to study the effect of ra in protecting brain during the period of acute cerebral ischemia.
