Withanolide A is a biologically active secondary metabolite occuring in roots and leaves of Withania somnifera. In the present study, adventitious roots from leaf explants of W. somnifera were induced for the production of withanolide-A by Agrobacterium tumefaciens strain C58C1 to obtain hair roots. Hair roots induction rate reached 30%. The withanolide A was determined by HPLC in different hair roots lines and different parts of W. somnifera. The average content of withanolide A in all hair roots lines were 1.96 times as high as that in wild-plant, the concentration of withanolide A in hair roots (1.783 mg x g(-1) dry weight) were 1.51 times as high as the roots of wild W. somnifera (1.180 mg x g(-1) dry weight), respectively. It is possible to obtain withanolide A from hair roots culture of W. somnifera.

Objective To investigate the effects of sufentanil on activation of spinal astrocytes in mice after unilateral sciatic nerve injury.Methods Eighty healthy male BALB/c mice,aged 6-8 weeks,weighing 18-22 g,were randomly divided into 4 groups (n=20 each): sufentanil high dose group (group H),middle dose group (group M),low dose group (group L) and model group (group MO).After model of sciatic nerve injury was established by unilateral sciatic nerve transection,group H,M and L,sufentanil 10 μg/kg,5 μg/kg,2.5 μg/kg was injected intraperitoneally once a day continuously for 3 days,while the equal volume of saline was injected in group MO.Five mice in each group were selected,and the sciatic nerve functional index were measured at 4,8,12 weeks.The 5 mice were sacrificed from each group and the damage on the same side L4-L6 segments of the spinal cord were removed at 2,4,8,12 weeks.The pathological changes were examined under light microscope at 8 week point.The expression of GFAP was determinatied at each time points by immuno-histochemistry.Results Compared with group L and MO,sciatic nerve functional index significantly was increased in groups H and M (P<0.05),and no significantly change was found in group L.Spinal cord neurons had a better morphology in groups H and M than in group L and MO.Compared with group MO,The expression of GFAP were significantly up-regulated in groups H,M and L (P<0.05).Compared with group L,the expression of GFAP were significantly up-regulated in groups H and M (P<0.05).Conclusion Sufentanil promotes spinal astrocyte activation after peripheral nerve injury in mice and improves repair after peripheral nerve injury.

Objective To evaluate the effects of sufentanil on regeneration and repair after single sciatic nerve injury in mice. Methods Seventy?five healthy male BALB∕c mice, aged 6-8 weeks, weig?hing 18-22 g, were divided into 5 groups ( n=15 each) using a random number table: peripherial nerve injury group (group PNI), low, medium and high doses of sufentanil groups (L, M and H groups) and cyclosporine A group ( group C) . The model of unilateral sciatic nerve transection was established in the 5 groups. In L, M and H groups, sufentanil 2?5, 5?0 and 10?0 μg∕kg were injected intraperitoneally, re?spectively, once a day for 3 consecutive days. Cyclosporine A 50 mg∕kg was injected intraperitoneally once a day for 3 consecutive days in group C. The equal volume of normal saline was given once a day for 3 con?secutive days in group PNI. Neurophysiological monitoring was performed at 4, 8 and 12 weeks after opera?tion, the amplitude of compound muscle action potentials of the sciatic nerve was recorded, and the nerve conduction velocity was measured. At 8 weeks after operation, 5 mice were sacrificed, the sciatic nerve 0?5 cm of the upper and lower the anastomosed site was removed for examination of the morphology of myelin sheath with light microscope, and the number of nerve fibers was calculated. Results Compared with group PNI, the amplitude of compound muscle action potentials of the sciatic nerve, nerve conduction ve?locity and the number of nerve fibers was were significantly increased in M, H and C groups ( P<0?05) , and no significant change was found in the parameters mentioned above in group L ( P>0?05 ) . Myelin sheath arrangement was severely irregular, and more vacuoles were found in group PNI. Myelin sheath ar?rangement was irregular, and more vacuoles were found in group L. Myelin sheath arrangement was mainly regular, and vacuoles were found occasionally in group M. Myelin sheath arrangement was regular, and no vacuoles were observed in H and C groups. Conclusion Sufentanil can promote regeneration and repair af?ter peripheral nerve injury in mice.
