美托洛尔治疗重症充血性心力衰竭的临床观察

近年来已认识到导致心力衰竭(congestive heart failure,CHF)发生发展的基本机制是心肌重塑.神经内分泌的激活,对心肌的生物学功能产生了不良的作用,加速了CHF的进展.由于CHF治疗模式的改善[1],为临床治疗CHF 提供了更有效的方法及药物.我院在2004年至2005年联合应用美托洛尔治疗重症CHF,现报告如下.     

川芎嗪对老年肺心病患者肺动脉高压的作用

应用钙拮抗剂、转换酶抑制剂等扩血管药物治疗老年慢性肺心病(CPHD)患肺动脉高压(PAH)时可发生低血压反应。川芎嗪为中药单体，有降低低氧PAH的作用，且不影响动脉血压，本对32例老年CPHD伴PAH患应用川芎嗪治疗，观察其血液动力学及神经内分泌激素变化，评价其疗效。     

家兔呼吸道内分泌细胞的形态学研究

研究新生仔兔和成兔呼吸道内分泌细胞的形态结构及分布，结果显示在呼吸道有单个物成群的内分泌细胞，单个的内分泌细胞从喉直至肺内导气部粘膜上皮内均可观察到，细胞形态多样，细胞胞质充满大量银染黑色颗粒；成群的内分泌细胞，仅分布于肺的支气管树粘膜上皮内，由几个或几十内分泌细胞组成圆形或卵圆形的小体，细胞胞南内也有大一银染黑色颗粒。

Functional Maturation of Neuroendocrine Gonadal Axis is Altered by Specific Phase Relations of Circadian Neurotransmitter Activity in Japanese Quail

The preset study was designed to ascertain the effects of temporal relationship of circadian neural oscillations on puberty attainment and reproductive growth of Japances Quail,Coturnix coturnix japonica,Serotonin and dopamine precursors(5-hydroxytryptophan,5-HTP and L-dihydroxyphenylalanine,L-DOPA,5mg/100g body weight)were injected daily,8and 12h apart in two groups of one-day ld chick,while cotrols received two daily injections of normal saline.Weekly/biweekly observations(body weight,cloacal gland size,testicular volume and activity,ovarian follicular diameter and rate of egg production)were made until 9 weeks of age,when the experiment was terminated.Results indicate that 8 h relationship completely suppressed gonadal growth even under long photoperiod(LD16:8),while a 12 h relationship induced precocious sexual maturity and increased the rate of reproductin(spermatogenesis and egg production).It is concluded that circadian phase relationship of serotonergic and dopaminergic activity may not only determine the onset of reproduction in this pultry species,but may also alter the rate of reproduction possibly by affecting photoperiodic mechanism of reproductive regulation.
