Example 60

(229) The solutions of products obtained in Examples 3-32 were prepared, as the method of Example 33, and kept for use.

(230) Selected above micelle, positive control lidocaine, and negative control normal saline were respectively administrated to 28 groups of test rats fully adapted to experiment environment, with five rats for each group. The administration dosage is: the concentration of lidocaine group being 2% aqueous solution (84 mmol/L), and the concentration of tested drug being 5 mmol/L. The injection volume of each rat receiving drugs or the control was 0.2 ml, and the drug or the control was injected to close to sciatic nerve of rats by guidance of nerve locator.

(231) Specific procedures and the evaluation criterion for local anesthetic effect were as follows:

(232) Blocking of Sciatic Nerve

(233) The tested rats were placed on bench board and allowed to inhale 5% isoflurane. After body-righting reflex abolition, rats are allowed to continue inhaling 1.5% isoflurane, to keep anesthesia. Keeping left-lateral position, their corresponding injection area sacrococygeal region was shaved, then routine sterilization and draping were performed. Two osseous anatomic landmarks greater trochanter of femur and tuber is chiadicum were laid hands, and the middle point of this line was the needle insertion position. If skin was taut, 1 ml injector was inserted along perpendicular of skin. When needlepoint reached hucklebone, the insertion was finished. Once no blood return was found as suction, 0.2 ml drug solution was slowly injected. Needle was lifted, and is oflurane was shut off. Animals were placed in observation cage until they naturally awakened.

(234) Observation of Effect on Serve Blocking:

(235) 10 min, 30 min, 60 min after injection, and afterward one hour per 4 hours, then two hour per 12 h, 18 h, 24 h, till five days, two persons investigated the following ethology of rats, who did not know about the treatment of rats.

(236) Mechanical Withdrawal Threshold (VFH):

(237) Rats were placed in transparent observation cages with a bottom of smooth metal sieve plate, and the corrected von frey filament was used to stimulate the foot lateral skin of rats (innervated region of sciatic nerve) from down to up. Von frey filaments were used from 0.4 g, and gradually increased to 60 g. For each stimulation, slightly bent of filament was used as a standard, or rats moved aside this side of limbs. Otherwise, once the stimulation time reached 3 s, operator stopped stimulating. Three tests were carried out for each time point, and the interval between two tests was 5 min, to avoid sensibilization.

(238) If the mechanical withdrawal threshold value was more than 60 g, the nerve blocking was considered as effective. The interval from completion of injection to the time point obtaining the first mechanical withdrawal threshold value of above 60 g was the effective time of the mechanical pain sensation blocking; the interval from completion of injection to the time that the mechanical withdrawal threshold value firstly decreased to less than 60 g was the ineffective time of the mechanical pain sensation blocking; their difference was the hold time of the mechanical pain sensation blocking.

(239) Motor Function:

(240) The hindlimb postural extensor thrust (PET) was used for evaluation. Rats were lifted vertically and their hindlimbs of injection side stepped on the top of electronic balance. At this time, the postural extensor thrust was shown as the value of balance. When limbs were completely paralytic, the digital reading was the weight of limbs, about 20 g. If the test value was more than half of the difference between the baseline and the limbs weight, the motor function was taken as recovery; If less than or equal to half of the difference, the motor function was taken as deprivation.

(241) The interval between completion of injection and the time point that the motor function was firstly deprivated was the time of effective motor blocking; the interval between completion of injection and the time point that the motor function was firstly recovered was the time of ineffective motor blocking; their difference was the hold time of motor blocking.
