The paper aims to explore the studying method for the pharmacokinetics of drugs in target organs, the pharmacokinetic process of tramadol hydrochloride in the extracellular fluid of frontal cortex (FrCx) of mice was investigated. Six male mice (Kunming strain) were anaesthetized (urethane, 1.8 g x kg(-1), ip) and secured on a stereotaxic frame. A microdialysis probe was implanted into the FrCx and perfused with artificial cerebrospinal fluid at a flow rate of 2 microL x min(-1). One hour later, mice were administrated (ip) with tramadol hydrochloride (50 mg x kg(-1)) and dialysates were collected continuously at 12-min intervals (24 microL each) for 6 h. The tramadol concentration in dialysates was determined by HPLC-Ultraviolet detection method, and the concentration-time curve and pharmacokinetic parameters of tramadol were calculated with DAS software. The results showed that the pharmacokinetic process of tramadol in the FrCx extracellular fluid of mice was fitted to a two-compartment open model, and the main pharmacokinetic parameters t1/2alpha, t1/2beta, t(max), C(max) and AUC(0-infinity) were (0.27 +/- 0.05) h, (2.72 +/- 0.24) h, (0.50 +/- 0.10) h, (2 110.37 +/- 291.22) microg x L(-1) and (4 474.51 +/- 441.79) microg x L(-1) x h, respectively. In conclusion, a studying method for pharmacokinetics of drugs in the target organ is established, which is simple and feasible. Tramadol hydrochloride shows a two-compartment model in the extracellular fluid of the mouse FrCx, and the distribution- and elimination half-life are 0.5 h and 2.7 h, respectively.

BACKGROUND:Lumbar fusion is a conventional effective measure to treat spondylolisthesis, spinal stenosis or with deformity. Bilateral pedicle screw fixation is recognized as the standard treatment for various spinal disorders, and has biomechanical and clinical advantages. OBJECTIVE:To evaluate the effects of bilateral pedicle screw fixation in the repair of lumbar disc herniation to restore disc height from the angle of imaging. METHODS: Clinical data of 42 patients with lumbar disc herniation were retrospectively analyzed. They al received bilateral pedicle screw fixation. Pain was evaluated before implantation, immediately and 1 month after implantation using Japanese Orthopaedic Association score of lower back pain and visual analog scale score. X-ray including anteriorposterior and lateral films of lumbar spine and MRI were used. CT was utilized to verify screw placement conditions and complications. RESULTS AND CONCLUSION:A total of 42 patients were folowed up for 3-6 months. Compared with pre-implantation, Japanese Orthopaedic Association score and visual analog scale score were significantly improved immediately after implantation (P < 0.01). There was no significant difference in Japanese Orthopaedic Association score between 1 month and immediately after implantation (P > 0.05). The height of intervertebral discs was significantly higher immediately and 1 month after implantation than pre-implantation (P < 0.01). The symptoms were lessened after fixation in al cases, and their qualities of life elevated. At 1 month, X-ray films and CT images revealed that no screw loosening, breakage or displacement occurred. The height of intervertebral discs was perfectly restored. No adverse events appeared in patients. These data indicate that bilateral pedicle screw fixation for lumbar intervertebral disc herniation can effectively restore the height of intervertebral discs, improve clinical symptoms and have biological and clinical superiority.
