The rats in groups IV, V, VI and VII were injected with numerous HSV vectors at the website from the spared DRG. The rats have been then subjected to additional evaluation. They had been permitted to survive for 28 days postoperatively (dpo) as described in Table I. Before the surgical procedure, the animals were deeply anesthetized with an intraperitoneal injection of pentobarbital sodium answer (2 ; 40 mgkg physique weight).

The articular processes of the respective vertebrae were removed having a pair of rongeurs and also the dura was cut with a smaller pair of scissors. The L1L4 and L6 DRGs have been exposed and removed at their respective intervertebral foramina, leaving the L5 DRG intact. Following surgery, the overlaying skin and muscle were sutured, and suitable postoperative care was offered frequently. All injections in to the DRG were performed working with a microprocessorcontrolled injection system employing direct piston displacement (Nanoliter 2000; Globe Precision Instruments, Sarasota, FL, USA) mounted on a micromanipulator as described previously (27). For direct injection into the spared L5 DRG, the foramen was enlarged in a cephalad direction making use of the rongeurs, in order to get rid of a 1mmdeep crescent of laminar bone, exposing the distal third from the DRG. A total of 2 HSVIGF1, HSVsiRNAIGF1, or the connected manage HSVpNXCMV and HSVpNXU6 vectors, respectively, have been injected into the DRG at a rate of 20 nlsec. Following completion in the injection, the pipette was left in location for five min prior to removal to allow the fluid to distribute along with the stress within the tissue to equalize. The wound was closed in layers. EA therapy. The rats in Groups IIIVII have been subjected to EA remedy at two paired acupoints, zusanli (ST 36)xuanzhong (GB 39) and futu (ST 32)sanyinjiao (SP six) (7,28). Their places were as follows: ST 36 is located 0.5 cm below the front of the fibula head; GB 39, 1.0 cm above the front from the lateral malleolus; ST 32, 1.5 cm above the reduced end of the patella; and SP 6, 0.5 cm above the posterior end of the medial malleolus. These acupoints are recognized to lie in the dermatome of L5 as described in preceding report (7). The rats have been placed in plastic holders to prevent movement of their body and hindlimbs when treated with EA, with all the animals remaining awake without having anesthesia in a hassle-free and secure manner. When the rats had been acclimate.
