OBJECTIVETo study the effects of lead acetate on the expression of brain-derived neurotropic factor (BDNF) and its receptor P75NTR in rat brain.

METHODSLead acetate was given to SD rats by intraperitoneal injection (ip) for 5 days at the dosage of 25, 50 and 100mg/kg body weight respectively. The contents of lead in serum, cerebral cortex and hippocampus were measured by atomic absorption spectrophotochemistry. The levels of BDNF mRNA and protein expression in cerebral cortex and hippocampus were observed by RT-PCR and immunohistochemistry, respectively. The levels of P75NTR protein expression in rat brain were measured by immunohistochemistry.

RESULTSCompared with the control, the contents of lead were significantly increased in serum, cerebral cortex and hippocampus in the treatment groups respectively (P < 0.01, P < 0.05). The BDNF mRNA expression in the cerebral cortex (0.52 +/- 0.05, 0.33 +/- 0.03) and hippocampus (0.77 +/- 0.10, 0.92 +/- 0.08) of 50, 100 mg/kg treated groups was significantly higher than that of the control group (0.52 +/- 0.05, 0.33 +/- 0.03), respectively (P < 0.05). The results of immunohistochemistry showed that the area density of BDNF protein in cerebral cortex of every treatment group (0.040 +/- 0.027, 0.048 +/- 0.027, 0.086 +/- 0.040) was significantly increased whereas the average gray value (187.11 +/- 11.15, 180.53 +/- 5.82, 180.15 +/- 8.01) was significantly lower than that of the control (0.026 +/- 0.005, 204.98 +/- 3.45) (P < 0.05, P < 0.01). The area density of BDNF protein in hippocampus of every treatment group was 0.040 +/- 0.027, 0.048 +/- 0.027, 0.086 +/- 0.040, respectively, which was significantly increased compared with the control (0.045 +/- 0.019, P < 0.05). The average gray value of BDNF protein in hippocampus (181.03 +/- 5.16, 171.25 +/- 12.65) of 50, 100 mg/kg were significantly lower than that of the control (198.98 +/- 6.40, P < 0.01). There was no positive expression of P75NTR protein in the control and 25 mg/kg body weight groups. The positive expression of P75NTR protein was detected in 50 and 100 mg/kg body weight groups.

CONCLUSIONLead can increase the BDNF and P75NTR expression in rat brain which might play an important role in the neural damage and repair.

Objective To evaluate the application of intraoperative real-time ultrasound combined with neuronavigation in surgical resection of deep intracranial lesions. Methods Fifteen patients with deep intracranial lesions underwent surgical resection of the lesions with guidance by Brain-Lab neuronavigation and intraoperative real-time ultrasound. The lesions were localized by ultrasound, and in cases of brain shift, intraoperative real-time ultrasound was used for lesion relocalization, surgical guidance, and monitoring of the tumor remnants during the operation. Results The lesions and their surrounding structures were accurately localized. Intraoperative real-time ultrasound identified brain shift of varying degrees, which was corrected under ultrasound guidance. Total resection of the lesions was achieved in 12 cases, and subtotal resection was performed in 2 cases. In the other case, the inflammatory lesion was identified as chronic granuloma by biopsy. All the patients showed improvements of the clinical symptoms after the operations. Conclusion Intraoperative real-time ultrasound during neuronavigation allows accurate localization of deep intracranial lesions and facilitates preoperative surgical planning to define the scope of resection, avoid the cortical brain tissue and important deep structures, and help evaluate the lesion residues for a second operation. Intraoperative real-time ultrasound may help improve the therapeutic effects and reduce the surgical complications.
