解磷注射液救治急性有机磷农药中毒34例临床报告

将急性有机磷农药中毒患者69例随机分为2组,一组主要应用解磷注射液治疗(新疗法34例),另一组(35例)主要应用阿托品治疗。两组治愈率分别为97.1％及77.1％,疗效比较差异显著(P<0.05)。新疗法的优点是起效快,作用持久,疗程短(两组比较P<0.001),副反应轻,值得推广应用。并就应用方法及注意事项等作了探讨,也强调了早期足量用药的重要性。     

安吉复口服液的耐缺氧,耐低温和抗疲劳作用

采用缺氧、寒冷和负重游泳等方法,观察了安吉复口服液(0.025、0.1和0.4mg·kg~(-1),ig,qd×14d)对小鼠的耐缺氧、耐低温及抗疲劳作用.结果表明,安吉复口服液0.1、0.4mg·kg~(-1)可延长KCN中毒小鼠的存活时间及延长小鼠在寒冷环境中存活时间,而0.4mg·kg~(-1)可延长常压缺氧条件下小鼠存活时间及延长小鼠负重游泳时间.     

核素显像对小儿消化道出血的病因诊断

目的探讨核素显像对小儿消化道出血，特别是对Ｍｅｃｋｅｌ憩室、肠重复畸形的病因诊断的价值。方法对２６例腹痛、便血为主要症状的患儿行９９ｍ锝酸盐（９９ｍＴｃＯ－４）显像，其中１２例显像阴性者于检查后２４小时有活动性出血者，再行９９ｍ锝标记红细胞显像。所有病例的诊断均经手术、病理及内窥镜等检查所证实。结果９９ｍＴｃＯ－４显像诊断Ｍｅｃｋｅｌ憩室和肠重复畸形的敏感性、特异性、准确性分别为８５．７％（１２／１４）、９１．７％（１１／１２）及８８．５％（２３／２６）。结论核素显像具有无创、方法简单易行等特点，特别是对异位胃粘膜诊断具有较好的灵敏性和特异性。核素显像可作为下消化道出血病因诊断的有效方法。     

Adjunctive therapy with bromocriptine in Parkinson's disease

Patients with moderately severe Parkinson's disease complicated by the adverse effects of chronic levodopa use benefited from the addition of bromocriptine (Parlodel; Sandoz) in doses up to 26 mg daily, which allowed an approximate 30% reduction of levodopa dose. This resulted in a significant decrease in the amount of levodopa side-effects while maintaining or improving the original parkinsonian clinical stage. Increased effectiveness in these patients was not associated with increased dosage beyond 25-30 mg daily. When the doses of bromocriptine were increased slowly, the adverse reactions were minor and usually transient.     

蜂王浆冻干粉对小鼠肿瘤的抑制作用

目的研究蜂王浆冻干粉对小鼠肿瘤的抑制作用.方法按每公斤体重0g、0.25g、0.50g、0.75g设对照及低、中、高3个剂量组,经口给予蜂王浆冻干粉30d后,接种小鼠肉瘤180(S180)和艾氏癌腹水型(EAC)两个瘤种.结果在两次重复的小鼠S180和EAC抑瘤试验中发现中剂量组瘤重明显低于阴性对照组(P<0.05),抑制率可达34%;中剂量组荷瘤小鼠平均生存时间均明显高于对照组(P<0.05).结论蜂王浆冻干粉具有抑制肿瘤的作用.     

高龄初产妊高征孕妇过氧化反应的研究

目的：探讨高龄初产妊高征孕妇体内过氧化反应。方法：测定正常初产妇、妊高征孕妇妊娠晚期母血过氧化脂质（LPO）、超氧化物歧化酶（DOD）的含量。结果：1．高龄初产妇母血LPO较非高龄初产妇明显升高，SOD明显下降，P＜0．05。孕妇年龄与母血LPO呈明显正相关，与SOD呈明显负相关，P均＜0．05。2．妊高征孕妇LPO较正常孕妇显著增高，SOD显著下降，P＜0．05，并随病情加重LPO水平升高、SOD水平下降更为显著，P＜0．05。3．高龄初产妊高征孕妇母血LPO含量较非高龄初产妊高征孕妇明显增高，P＜0．05，而SOD则无显著变化，P＞0．05。4.妊高征孕妇胎儿宫内生长发育迟缓（IUGR）发生率较正常孕妇显著升高，P＜0．025，各组脐血清LPO、SOD含量无显著差异，P＜0．05。结论：高龄初产妊高征孕妇体内过氧化作用明显增强，LPO水平的升高可能为高龄初产妇妊高征发生率及IUGR发生率增加的原因之一。     

Anabolic and catabolic hormonal response of elite runners to training at high altitude

A 2-week training period 2000 meters above sea level performed by 6 male elite Swedish runners influenced neither basal anabolic (total and non-sex hormone-binding globulin (SHBG)-bound testosterone (NST) and insulin-like growth factor-1 (IGF-1) nor catabolic (cortisol) hormones when comparing serum levels prior to and after the training camp. The anabolic vs catabolic hormone balance, expressed as the NST: cortisol ratio, also remained unchanged as well as SHBG and body mass. Thus, training at 2000 meters above sea level, often practised by elite runners to improve performance in competition at sea level, does not result in a catabolic situation after return to sea level, as measured by peripheral hormones. However, the adaptation to high altitude was associated with a slight (NS) decrease in testosterone as well as in anabolic vs catabolic balance as measured the third day at high altitude. Simultaneously, a decrease in subjective performance was claimed by the runners, but could not be shown by objective measurements. From day 3 to day 9 at high altitude, all runners claimed a subjective recuperation of performance. Total and non-SHBG-bound testosterone increased significantly from day 3 at high altitude to the first post-camp sea-level test. The results reflect the necessity of adaptation when travelling to races at different altitudes. The Swedish runners had significantly higher cortisol, total testosterone and NST levels compared with basal values of a group of 17 elite Kenyan runners living and training at high altitude. Since the NST cortisol and IGF-1 values were not lower, a catabolic state or malnutrition was not likely to be present. The results might reflect an adaptation to altitude or ethnic variations.

Conjunctival involvement of lymphomatoid granulomatosis

Lymphomatoid granulomatosis is an angiocentric and angiodestructive lympho-proliferative disorder involving multisystems but rarely conjunctiva. We present a 62-year-old Chinese female with lymphomatoid granulomatosis who had an ulcerative conjunctival nodule. Conjunctival biopsy revealed pathological findings important for diagnosis and indicating progression of disease severity. To our knowledge, this is the first report to demonstrate pathological findings characteristic of lymphomatoid granulomatosis with conjunctival involvement.
