Chinese Journal of Tissue Engineering Research 2009;13(50):9866-9869
BACKGROUND: Nerve growth factor (NGF) plays a regulatory effect on survival, growth, differentiation, and egeneration of neurons. OBJECTIVE: To verify the therapy effects and the expression of Fos protein with different dose of NGF on the spinal cord of rats with neuropathic pain.DESIGN, TIME AND SETTING: The randomized controlled animal experiment was performed at the Shanghai Ninth People's Hospital.MATERIALS: A total of 72 male, health, adult, Wistar rats, weighing 180-200 g, were randomly divided into 4 groups, namely,model group and NGF with 4, 8, 16 Ijg groups, with 18 animals in each group.METHODS: All rats were prepared sciatic nerve chronic constriction injury models. Rats were intraperitoneal injected NGF with 4,8, 16 μg/(kg·d) in the experimental groups.MAIN OUTCOME MEASURES: ① Behavioral observation and mechanical pain threshold testing was performed prior to and at days 1,2, 3, 5, 7, 10, 14 after operation. ②Six of rats in each group were sacrificed at days 2, 7, and 14 after operation, and the expression of Fos protein in the spinal cord were assayed with the immunohistochemicat methods and image analysis.RESULTS: In the model group, rats raised and licked feet spontaneously after operatiOn, and the mechanical pain threshold was decreased from the 3rd day, and reached the lowest at day 14. However, in the NGF groups, rat exhibited no pontaneous pain,without subnormal period of mechanical pain threshold. The mechanical pain threshold in rats of the model group as significant different to the other groups at days 10 and 14 after operation (P < 0.05). The mechanical pain threshold in rats of all groups increased, but which of 16 μg NGF group was lower than the other groups on the first day after operation (P < 0.01 ) and lower than that of the 4 μg NGF group at 2 days after operation (P < 0.05). The expression of Fos protein in the spinal cord of the model group was increased than that of the other groups after operation (P < 0.01 ). The expression of Fos protein in the spinal cord of the 16 μg NGF group was less than that of model and 4 μg NGF groups at day 2 after operation (P < 0.01 ).CONCLUSION: NGF has therapeutical effect on neuropathic pain of rats, especially with large dosage. The mechanisms may be inhibiting the expression of Fos protein in the spinal cord of rats.

Objective To determine the association of anomalies of female reproductive system with that of urinary system. Methods Two hundred and eighty-nine cases, including 59 with congenital vaginal inclined septum syndrome, 135 with septate uterus, 4 with unicornuate uterus, 13 with rudimentary horn of uterus, 58 with congenital absence of the uterus and vagina, 14 with imperforated hymen, and 6 with atresia of vagina, treated during the past 4 years, were analysed retrospectively. Results Anomalies of urinary system were more frequently found in patients with anisomerous anomalies of reproductive system(85. 53% , 65/76 cases). In 59 cases of congenital vaginal inclined septum syndrome, 43 had ipsilateral renal agenesis, 2 had one single pelvic kidney, 1 had bilateral horseshoe kidneys, 1 had left-side horseshoe kidney, 1 had one pair of renal pelvis and renal calices with ureters incorporated at middle and inferior segments on both sides. Ipsilateral renal agenesis was also seen in patients with rudimentary horn of uterus(14/14 cases) and unicornuate uterus(4/4 cases). However, there was no urinary system malformation seen in septate uterus patients (0/135 cases), imperforated hymen (0/16) and atresia of vagina (0/4 cases). Only 1 case of congenital absence of the uterus and vagina associated with ipsilateral renal agenesis. Conclusion Anomalies of reproductive ducts associated with renal malformations, especially anisomerous anomalies of reproductive system are not unusual. Early recognition and diagnosis is very important to prevention and treatment of such diseases.
