The effect of an isoprenaline infusion on the splenic blood flow and intrasplenic platelet kinetics

The effect of a constant isoprenaline infusion on the venous platelet count, splenic blood flow and intrasplenic platelet kinetics was investigated in 6 healthy male volunteers. The study was carried out using autologous 111In-labelled platelets and dynamic gamma camera imaging of the initial distribution of radiolabelled platelets between blood and splenic platelet pool. The isoprenaline infusions were administered i.v. over 30 min in a dose of 0.03 micrograms/kg/min. These infusions significantly increased the splenic blood flow and the size of the exchangeable splenic platelet pool. Concomitantly, there was a decrease of labelled as well as unlabelled platelets in the peripheral blood. The intrasplenic platelet transit time was not affected. Before start of infusion, the splenic blood flow was 6.1 +/- 2.9 (SD) % of total blood volume/min and the splenic platelet pool size 34 +/- 9 (SD) %. During infusion the corresponding values were 8.7 +/- 3.9 (SD) and 41 +/- 11 (SD), respectively. It is concluded that an i.v. infusion of isoprenaline enhances splenic pooling of platelets as a result of an increase in splenic blood flow.     

Cerebral sodium sensors in the sodium-deplete sheep

The sodium intake of sodium deplete sheep was studied during local, push-pull perfusion of different solutions within the third cerebral ventricle. Sheep were made sodium deplete by continuous loss of parotid saliva, and were allowed access to 0.6 M NaHCO₃ solution for 2 h daily. Local perfusion within the third cerebral ventricle was performed before and during the access to sodium solution. Four perfusion sites were used: anterior dorsal and ventral, and posterior dorsal and ventral. Perfusion of 200 mM Na-csf caused a decrease in sodium intake at each perfusion site. Perfusion of ouabain, 10⁻⁶M, caused a reduction in sodium intake only during perfusions within the anterior portion of the third ventricle. The results may indicate that specific neuronal elements sensitive to changes in intracellular sodium concentrations are located around the anterior portion of the third cerebral ventricle. These neurones, however, are not exclusive sites from where sodium intake of sodium deplete sheep can be influenced.     

大鼠孤束核含酪氨酸羟化酶、神经降压素和胆囊收缩素样神经元向伏核的投射—HRP和免疫细胞化学双重标记法的研究

本文应用HRP顺、逆行追踪法结合免疫细胞化学双重标记法,对大鼠孤束核向伏核的投射进行了研究。主要结果如下:1.WGA-HRP注入孤束核尾侧段,在伏核后部的腹、内侧区,出现较密集的标记纤维、终末和标记细胞;将HRP注入伏核后部的腹、内侧区,在孤束核尾侧段(主要在连合核和内侧亚核)出现大量的顺、逆行标记,以同侧为主。2.HRP注射到伏核并结合免疫细胞化学反应,在孤束核尾侧段发现HRP-TH,HRP-NT、HRP-CCK双重标记细胞。HRP-TH的数目最多,其次是HRP-NT双标细胞,HRP-CCK双标细胞最少。     

Does ageing have an effect on midbrain premotor nuclei for vertical eye movements?

Currently, there is debate in the clinical literature as to whether defects in vertical gaze are a consequence of normal ageing or a component of an underlying neurodegenerative disorder. Although pathological changes have been demonstrated in diseased subjects, no study to date has addressed the question of normal ageing effects. In this retrospective study, we examined 23 neurologically and pathologically normal subjects (age 18-91). Using an unbiased, frame-based sampling method, we quantified neuronal and glial cell densities in 10 young (<50) and 13 aged (>65) subjects in the rostral interstitial nucleus of the medial longitudinal fasciculus (riMLF), the key premotor substrate in the vertical gaze pathway. We found no statistically significant difference in neuronal density, glial cell density, or neuron-to-glial cell ratios between the young and the aged. We conclude, therefore, that neuronal loss, neuronal atrophy, or gliosis in the riMLF are not consequences of normal ageing.     

经尿道等离子双极汽化电切(TUPKVP)治疗前列腺增生症580例

目的:探讨经尿道等离子前列腺双极汽化电切术(TUPKVP)治疗前列腺增生的效果。方法:回顾性分析580例良性前列腺增生(BPH)患者行TUPKVP的临床资料。结果:中转开放手术2例,切除前列腺组织10~80 g,平均32.5 g。手术时间25~150 min,平均60 min,术中输血10例,无电切综合征(TURS)发生。术后随访2~36个月,患者最大尿流率升高,IPSS症状评分值降低,排尿通畅,疗效好,并发症少。结论:TUPKVP出血少,手术安全,疗效确切,是治疗前列腺增生的有效方法。     

脾动脉栓塞治疗外伤性脾破裂28例临床疗效观察

目的：探讨脾动脉栓塞术对外伤性脾破裂的疗效及并发症的处理。方法：采用Seldinger法行脾动脉栓塞术治疗外伤性脾破裂28例。结果：所有患者出血立即停止，其中4例行2次栓塞。28例均有脾区疼痛，22例发热。脾动脉栓塞5天后血小板、白细胞上升近1倍，7天后恢复至正常范围。28例随访6－36月，查免疫球蛋白、CT等结果满意，未有再出血及发生暴发性感染。结论：脾动脉栓塞不但有良好的止血作用，而且能保留脾脏的免疫功能，可在非手术治疗失败时选用，是外伤性脾破裂的一种有效治疗方法。     

Prevalence of Parkinson's disease in Cantalejo, Spain: a door-to-door survey.

We assessed the prevalence of Parkinson's disease in Cantalejo, Spain. In 1994, we screened 1,579 persons (age > or = 40 years) using a high-sensitivity method. Cases fulfilling established clinical criteria were followed for a minimum of 3 years. Prevalences were compared with those from other door-to-door surveys. We detected 27 individuals with parkinsonism, 20 of whom had Parkinson's disease. The prevalence of Parkinson's disease increased with age and, when age-adjusted to European standards, was 9.01 per 1,000 (age 40 years and over; 10.78 in men and 5.23 in women). Of the 11 men, three were in Hoehn & Yahr grades III-IV, but six of the nine women were more severely affected. Overall, we found 18 newly diagnosed cases of parkinsonism, 13 of which were Parkinson's disease, and the majority of which were in men aged 80 years or older with a mean duration of illness of 5 years. Our prevalence figures are the highest reported, apparently because of the inclusion of several very elderly men. Parkinson's disease in Cantalejo is less severe in men than in women, particularly in those newly diagnosed. Despite the low numbers, the high prevalence and sex-related pattern are unexplained but they probably relate to the high sensitivity of the screening method.
