Rapid desensitization of 5-HT(1A) receptors in Fawn-Hooded rats after chronic fluoxetine treatment.

Anxiety, platelet serotonin (5-HT) content and functions of the 5-HT(1A) receptor agonist 8-hydroxy-2-(di-n-propylamino)tetralin (8-OH-DPAT) were measured in Sprague--Dawley (SD) and Fawn-Hooded (FH) rats, a strain with genetically impaired 5-HT storage and reuptake system and a putative model of depression and anxiety. In addition, the effects of 7 and 16 days treatment with the selective serotonin reuptake inhibitor (SSRI) fluoxetine on 8-OH-DPAT-induced responses were studied. FH rats showed significantly higher anxiety in the social interaction test, and much lower platelet 5-HT content compared to SD rats. The efficacy of 8-OH-DPAT (15-120 microg/kg, i.v.) to induce lower lip retraction (an effect mediated by median raphe receptors) was increased in FH rats. In most FH but only a few SD rats a special neurological syndrome, clonic movement of the masseters and in-and-out movement of the eyeballs, was induced by 8-OH-DPAT, and this behaviour like other effects of 8-OH-DPAT, was completely blocked by pretreatment with the 5-HT(1A) receptor antagonist WAY-100635. In SD rats fluoxetine (10 mg/kg/day, i.p.) caused a moderate inhibition of 8-OH-DPAT-induced hypothermia, an effect mediated most likely by hypothalamic 5-HT(1A) receptors, (-19% and -40% after 7 and 16 days of fluoxetine, 24 h after the last injection, respectively). In FH rats fluoxetine caused a rapid and complete reduction in the 8-OH-DPAT-induced hypothermia (-65% and -91% after 7 and 16 days of fluoxetine, respectively). Fluoxetine caused no change in lower lip retraction but a reduction in the masseter-eyeball syndrome in both SD and FH rats. Our data provide evidence that in FH rats, median raphe 5-HT(1A) receptors are hypersensitive, and the hypothalamic 5-HT(1A) receptor desensitization, caused by SSRI antidepressants, is faster and more complete. These data support the notion that chronic treatment with SSRIs induces a desensitization of some 5-HT(1A) receptor populations, and impaired 5-HT storage and reuptake may accelerate this process.     

格列美脲治疗2型糖尿病伴肥胖患者的临床效果及药理分析

目的 探讨2型糖尿病伴肥胖患者施以格列美脲治疗的临床效果,并作药理分析。方法 46例2型糖尿病伴肥胖患者,根据随机数字表法分为观察组和对照组,每组23例。对照组患者给予格列吡嗪缓释片治疗,观察组患者给予格列美脲片治疗。比较两组患者治疗前后血糖指标[空腹血糖(FPG)、餐后2 h血糖(2 h PG)、空腹胰岛素(FINS)、糖化血红蛋白(HbA1c)]、血脂[总胆固醇(TC)、甘油三酯(TG)、低密度脂蛋白胆固醇(LDL-C)]及体质量指数(BMI)。结果 治疗后,观察组患者FPG、2 h PG、FINS、HbA1c水平分别为(6.04±0.43)mmol/L、(11.12±2.52)mmol/L、(657.84±10.37)pmol/L、(6.46±0.58)%,均低于对照组的(7.45±0.27)mmol/L、(14.24±2.09)mmol/L、(704.29±11.09)pmol/L、(8.53±0.79)%,差异均具有统计学意义(P<0.05)。观察组患者TC、TG、LDL-C、BMI水平分别为(3.24±0.79)mmol/L、(1.88±0.69)mmol/L、(1.96±0.48)mmol/L、(23.05±2.55)kg/m2,均低于对照组的(4.75±0.38)mmol/L、(2.35±0.75)mmol/L、(2.95±0.66)mmol/L、(27.76±4.10)kg/m2,差异均具有统计学意义(P<0.05)。结论 以格列美脲治疗2型糖尿病伴肥胖患者,可使患者血糖及血脂水平得以有效控制,同时可减轻其肥胖程度,具较高应用价值。
