Medication compliance in elderly people: influencing variables and interventions

This paper describes a study in which 70 elderly patients were assessed for risk factors in their medication regimen They were separated into three study groups, including two levels of teaching intervention focused on the home medication administration system, and a control group The intervention utilizing a follow-up telephone call demonstrated a significant change in risk-related behaviours such as verbalization of the regimen, congruence between instructions and usage of medications, and taking of medicines not currently prescribed or over-the-counter     

用Fura-2测定周围血单个核细胞内游离钙浓度

本文用Fura-2测定了周围血单个核细胞内游离钙浓度，并对有关实验条件进行了探讨。对比研究表明，血标本在4℃保存4小时对测定结果无显著影响，测定标本中单个核细胞数以10~5～10~6/ml为宜。认为测定单个核细胞内游离钙浓度对判断单个核细胞的功能状况有一定帮助。     

Ag—NOR计数在区分良恶性甲状腺病变中的意义

随机选择经长期随访证实的滤泡性甲状腺癌和腺瘤各10例,正常甲状腺组织5例作为对照。按Ploton的染色方法和Crocker推荐的计数方法分别计算三组每例各50个细胞的Ag-NOR嗜银颗粒平均数,再算出三组各自的AgNOR均数,经统计学检验三者有极显著性差异。可望成为甲状腺滤泡性肿瘤良恶鉴别的一项辅助指标。     

神经导航辅助显微手术治疗脑功能区肿瘤

目的探讨神经导航系统辅助下脑重要功能区肿瘤显微手术的治疗效果和应用价值。方法1999年12月～2002年6月应用StealthStation神经导航系统辅助切除邻近脑重要功能区肿瘤10例,对神经导航系统术中应用的优越性、精确性等进行分析。结果本组平均注册误差为(2.8±0.9)mm,肿瘤和重要解剖功能结构定位准确,肿瘤全切除率77.8%。术后神经功能未受明显影响,无手术并发症及死亡。结论神经导航系统对于切除邻近脑重要功能区肿瘤具有定位准确,动态示踪和实时导航,侵袭性小,安全、可靠等特点,有助于提高肿瘤全切率及降低手术并发症。     

运动性肥大心肌活细胞胞浆游离Ca2+动态变化的激光共聚焦研究以及局部IGF-Ⅰ和AngⅡ的变化

目的:研究运动与心脏重塑过程中心肌胞浆游离Ca2 ([Ca2 ]c)动态变化的生物学机制.方法:采用激光扫描共聚焦显微技术(LSCM)对STDIn Ca2 荧光试剂负载的运动肥大心肌活细胞[Ca2 ]c动态变化进行研究,采用放射免疫测定运动小鼠心肌局部IGF-Ⅰ和AngⅡ含量.结果:运动肥大心肌[Ca2 ]c变化表现为基值稳态和峰值显著升高,达峰时间延长(P＜0.001).心肌局部IGF-Ⅰ和AngⅡ显著升高(P＜0.001).结论:运动性心肌肥大与[Ca2 ]c变化、机械信号、IGF-Ⅰ和AngⅡ关系密切,机械信号、IGF-Ⅰ和AngⅡ可能是引起[Ca2 ]c显著升高,增强心肌收缩能力的胞外刺激因素.     

Routine hysteroscopy for patients with a high risk of uterine malignancy

Summary. Seventy patients with abnormal vaginal bleeding were examined with a Storz hysteroscope. The examination took an average of only 5 min. Sixty patients had the examination under general anaesthesia, five under paracervical block and five had no form of anaesthesia. All tolerated the procedure well. There were no complications directly related to the hysteroscopic examination. There was complete correlation between the histology of the endometrium obtained at subsequent curettage and the hysteroscopic findings.     

尿中δ-氨基乙酰丙酸的测定——对铅中毒诊断意义的探讨

本调查是对××冶炼厂227名接铅工人作了尿铅、尿中δ-ALA、尿粪卟啉及末梢血中碱粒红细胞的测定,同时与对照组进行了比较。结果表明:(1)接铅工人尿中δ-ALA检出均高出非接铅健康工人,且差别非常显著。(2)随着接铅工龄的增加,工人尿中δ-ALA的超标率也相应的增多。(3)接铅工人尿中δ-ALA的变化比CP要早,对铅的接触更敏感。(4)尿中δ-ALA与尿铅呈明显相关,而与碱粒红细胞相关不明显。     

A cell line from Wilms' tumour with deletion in short arm of chromosome II

A cell line (T3/73) from a Wilms' tumour has been established from a 9 month-old boy with aniridia. The tumour was removed in 1973. On histological examination a diagnosis of Wilms' tumour was made which showed undifferentiated areas, marked tubule formation and abundant striped muscle fibres. The tumour cells, which are fusiform, grew rapidly in culture without the addition of growth factors, and have undergone over 100 passages. Approximately 95% and 5% were positive for desmin and cytokeratin, respectively. The cell doubling time was 28 hr. Cytogenetic studies revealed a karyotype of 46,XY,del(11) (p12::p14). Although the cells stained very intensely with a monoclonal antibody that detects oncogene ras p 21 antigen, Southern blot analysis using c-Ha-ras as a probe failed to reveal an obvious deletion or amplification of either Ha-ras allele.     

鸡和大鼠小脑发育的比较观察

观察发育阶段不同的鸡和大鼠的小脑标本外形,并在光学显微镜和电子显微镜下观察了结构。鸡卵在孵育的第6天,小脑原基出现。第15天小脑皮质形成,普肯野氏细胞(普氏细胞)排成一层。新生鸡小脑皮质发育近成年状态,普氏细胞发育基本完成。大鼠在生后第5天小脑皮质形成,第20天发育成熟。在生后第5天普氏细胞排成一层,第20天接近成熟状态,此时在电子显微镜下显示为粗面内质网和多聚核蛋白体区域性集中分布。鸡小脑比大鼠小脑发育早,这是种属差异。
