Aim To investigate the extent of systemic absorption and uptake of meptazinol (MEP) hydrochloride in cerebrospinal fluid (CSF) after intranasal administration on rats and compare with oral administration. Methods CSF samples were collected by a serial sampling method. The concentration of MEP in the biological samples was measured by HPLC with fluorescence detector. Results Rapid and significant levels of MEP in plasma and CSF can be achieved after nasal administration whereas the oral administration resulted in considerably lower drug concentrations. AUC in plasma and CSF from the nasal route are 7.375 and 15.6 folds compared with those of the oral route, respectively. Conclusion Intranasal MEP is able to show quick absorption and improve the bioavailability, which could be a promising alternative to oral administration.

Objective To detect serum level of anti-M-type phospholipase A2 receptor (PLA2R) antibody in elderly patients with idiopathic membranous nephropathy (IMN) and to explore its clinical significance in IMN disease.Methods A total of 134 patients with renal biopsy-proved glomerular diseases were enrolled in this study,including 42 elderly cases with IMN,45 non-elderly cases with IMN,19 elderly cases with minimal change nephropathy (MCN),12 elderly cases with IgA nephropathy (IgAN),8 elderly cases with hepatitis B-associated membranous nephropathy (HBV-MN) and 8 elderly cases with focal segmental glomerulosclerosis (FSGS).Western blotting was used to detect serum anti-PLA2R antibody and the correlation of anti-PLA2R antibody with laboratory parameters in elderly IMN patients was analyzed.Results The elderly and non-elderly patients with IMN showed that the positive rate of anti-PLA2R antibody was 71.4％ and 73.3％,respectively (P＞ 0.05).The positive rate of anti-PLA2R antibody in elderly IgA nephropathy,HBV-MN and MCN patients was 16.7 ％,12.5％ and 5.3％ respectively.Anti-PLA2R antibody was not detected in serum from elderly FSGS patients.The positive rates of serum anti-PLA2R antibody were significantly higher in both elderly and non-elderly IMN patients than in elderly patients with secondary MN and other types of glomerlonephritis (P ＜ 0.01).Furthermore,anti-PLA2R autoantibody level was positively correlated with 24-hour urine protein level and negatively correlated with the concentration of serum albumin in elderly patients with IMN (P＜0.01).Conclusions Anti-PLA2R antibody is a sensitive serological marker of IMN.Detection for anti-PLA2R antibody might be helpful for the diagnosis of both elderly and non-elderly IMN and for the monitor of IMN disease severity.

AIM: To explore the effect of melatonin (MLT) on the apoptosis of thymocytes and splenocytes in mice induced by ionizing radiation and its mechanism. METHODS: The percentages of apoptotic bodies and the DNA lytic rates of thymocytes and splenocytes in mice in vitro and in vivo were detected with flow cytometry and fluorospectrophotometry, respectively. RESULTS: The apoptosis of mouse thymocytes and splenocytes in vitro increased with significant dose-dependence in 0 5-6 0 Gy X-irradiation. When MLT of 2 mmol?L -1 was added into thymocytes or splenocytes in vitro before irradiation with 0 5-6 0 Gy X-rays, the percentages of apoptotic bodies and the DNA lytic rates all decreased significantly as compared with those in the irradiation group. The percentages of apoptotic bodies in these two kinds of cells were 86 25% and 89 22% of those in the irradiation group, respectively, and the DNA lytic rates were 87 23% and 89 16%, respectively. When MLT was injected into intraperitonium in mice 60 min before whole-body irradiation with 2 Gy X-rays, the percentages of apoptotic bodies and the DNA lytic rates were significantly lower than those in the irradiation group, and near or lower than those in the sham-irradiation group. MLT of 0 1-2 5 mg/kg decreased the lymphocyte apoptosis, but without significant dose-dependence. CONCLUSION: The protective effects of MLT on mouse lymphocytes damaged by irradiation in vivo are obvious than those in vitro. [
