N-硝基-L-精氨酸抗阿片类精神依赖作用

 目的研究N-硝基-L-精氨酸(NO₂Arg)在吗啡、二氢埃托啡精神依赖形成中的作用。方法采用小鼠腹腔注射吗啡、二氢埃托啡的方法建立小鼠精神依赖的条件性位置偏爱模型；采用荧光内过滤法测定小鼠脑内NO的含量；小鼠脑内cAMP/cGMP含量采用放射免疫法测定。结果小鼠吗啡、二氢埃托啡精神依赖形成过程中脑内NO，cAMP，cGMP的含量显著上升；腹腔注射NO₂Arg5mg·kg^-1可抑制吗啡、二氢埃托啡精神依赖升高小鼠脑内NO，cAMP，cGMP含量的作用。结论NO在易化阿片类药物精神依赖形成中可能有一定作用；NO₂Arg 抑制吗啡、二氢埃托啡精神依赖形成的作用可能是通过减少小鼠脑内NO合成和调节cGMP/cAMP水平介导的。

Metabolism and pharmacokinetics of a dipeptidyl peptidase IV inhibitor in rats, dogs, and monkeys with selective carbamoyl glucuronidation of the primary amine in dogs.

The pharmacokinetics and metabolism of the l-threo isoleucine thiazolidide dipeptidyl peptidase IV inhibitor, di-[2S,3S]-2-amino-3-methyl-pentanoic-1,3-thiazolidine fumarate (ILT-threo) and its allo stereoisomer (ILT-allo) were evaluated in rats, dogs, and monkeys. Both compounds were well absorbed (>80%) in all species, and most of the dose (>60%) was recovered in urine. Metabolites identified in all species included a sulfoxide (M1), a sulfone (M2), and a carbamoyl glucuronide (M3). For both compounds, parent drug had moderate systemic clearance in rats and dogs ( approximately 20-35 ml/min/kg in both species) and lower clearance in monkeys ( approximately 6-9 ml/min/kg). In rats, M1 was present in systemic circulation in concentrations similar to that of parent drug, whereas in dogs and monkeys, exposures to M1 were higher than for parent drug. In dogs, exposures to the sulfoxide metabolite were approximately 2 to 3 times higher after administration of ILT-allo than after administration of ILT-threo. Carbamoyl glucuronidation was an important biotransformation pathway in dogs. Circulating levels of M3 were significant in the dog, and present only in trace levels in rats and monkeys. M3 could be produced in in vitro systems in a NaHCO3 buffer under a CO2-saturated atmosphere and in the presence of UDP-glucuronic acid and alamethicin.

Expression of hepatoma-derived growth factor is a strong prognostic predictor for patients with early-stage non-small-cell lung cancer.

PURPOSE: Hepatoma-derived growth factor (HDGF), which is unrelated to hepatocyte growth factor, can stimulate DNA synthesis and cell proliferation on entering the nucleus. We hypothesize that HDGF plays an important role in biologic behavior of early-stage non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS: Ninety-eight patients with pathologic stage I NSCLC who underwent curative surgery were studied. Immunohistochemistry was used to determine the expression level of HDGF in the tumor specimens. The intensity of the protein staining and percentage of stained tumor cells were used to determine a labeling index. Statistical analyses, all two-sided, were performed to determine the prognostic effect of HDGF expression levels on clinical parameters and outcomes. RESULTS: The mean +/- standard deviation HDGF labeling index in the 98 tumors was 185 +/- 41. Patients whose tumors had higher HDGF indexes (>/= 185) had a significantly poorer probability of overall survival at 5 years after surgery than did those with lower HDGF indexes (0.26 v 0.82; P <.0001). Similarly, the 5-year disease-specific and disease-free survival probabilities were lower in those with higher HDGF indexes (0.42 v 0.92, and 0.34 v 0.71; P <.0001 and P =.0008; respectively). Multivariate analysis indicated that HDGF level was an independent predictor of overall, disease-specific, and disease-free survivals. CONCLUSION: Overexpression of HDGF is common in early-stage NSCLC. The expression level in tumor cells is strongly correlated with poor overall, disease-specific, and disease-free survivals, suggesting HDGF may be a powerful prognostic marker for patients with early-stage NSCLC.
