Long-term outcome in 134 patients with galactosaemia

In a retrospective study 134 galactosaemic patients, born between 1955 and 1989 in the Federal Republic of Germany were traced and their long-term outcome evaluated. We investigated 83 galactosaemic patients (78 homozygotes, 5 compound heterozygotes) by clinical, psychometric and laboratory testing; 31 patients were evaluated by medical history, the remaining 20 patients had died due to sequelae of the underlying disease. In 48 out of 78 classical galactosaemia patients galactose-free therapy had been started before the 15th day, in 19 between days 15 and 56 and in 11 patients after the 56th day. Physical findings revealed that puberty was delayed in 1 out of 18 males and 6 out of 11 females. Neurological abnormalities included ataxia (n=6), intention tremor (n=11) and microcephaly (n=10). Speech abnormalities were found in 43 out of 66 patients over 3 years of age and disturbance of visual perception and/or arithmetic deficits in 29. Intelligence declined with age, i.e., a DQ or IQ less than 85 was found in 4 out of 34 patients less than 6 years of age (12%), in 10 out of 18 between 7 and 12 years (56%) and in 20 out of 24 older than 12 years (83%). Metabolite patterns (RBC galactose-1-phosphate and UDP-galactose, plasma and urinary galactitol) did not correlate with DQ or IQ. Dietary compliance was good in almost all patients. Compound heterozygotes (n=5) had normal mental and growth development and all laboratory parameters were in the normal range. The cause of the unsatisfactory outcome of well-treated galactosaemic patients with disturbances in long-term development remains unclear. This could be due to a chronic intoxication of galactose metabolites or a deficiency of UDP-galactose or galactose-containing glycoproteins or glycolipids.This study was supported by a grant from the Stifterverband für die Deutsche Wissenschaft (Huebner-stiftung), grant TS 114/18/89 and by the Arbeitsgemeinschaft für Pädiatrische Stoffwechselstörungen     

细菌内毒素对缺氧缺血性脑损伤新生大鼠远期智能的影响

目的：探讨细菌内毒素脂多糖（LPS）对缺氧缺血性脑损伤（HIBD）新生大鼠远期智能的影响，方法，建立新生大鼠LPS＋HIBD模型，于新生大鼠缺氧前4h给予腹腔注射LPS0．3mg/kg,HIBD组和对照组仅给予腹腔注射生理盐水，采用迷宫实验观察远期学习记忆能力的改变。结果：LPS＋HIBD组学习记忆能力明显低于HIBD组，表现在达标所需反映次数明显高于HIBD组（P＜0．05），而正确率支明显低于HIBD组（P＜0．05），结论：LPS对缺氧缺血引起的脑损伤有增敏作用，可进一步降低HIBD后的学习和记忆能力。

母亲孕期先兆流产与儿童智力发育相关性研究

目的探讨孕期先兆流产对所出生儿童智力发育的影响情况,为进一步做好围产期保健和儿童保健工作提供科学理论基础。方法在广州市海珠区随机分层抽取公立、厂企街道及私立等不同性质托幼机构各10间,分别对175名先兆流产组4￣7岁儿童和182名正常对照组同龄儿童采用调查问卷,详细询问一般情况、孕期及分娩情况、儿童生长发育及教育情况等;同时对两组研究对象进行韦氏智力测验,并进行单因素分析以及多因素分析等统计学处理。结果母亲孕期先兆流产对出生儿童智力发育有负面影响,主要表现在言语智商和总智商方面。结论应尽量避免各种原因造成的先兆流产,进一步深入研究先兆流产与儿童智力发育的关系及其生物医学机制,积极寻找先兆流产后既能继续妊娠又不影响儿童智力发育的科学干预措施,加强先兆流产后出生儿童的保健、教育工作,弥补先兆流产对儿童智商所造成的不良影响。     

扶元补脑冲剂对老年性痴呆鼠脑ATP酶及脂质过氧化反应的影响

目的:研究扶元补脑冲剂(红参、山楂、黄芪、淫羊藿、丹参、泽泻、石菖蒲)对老年性痴呆鼠脑ATP酶活性、自由基含量及脑系数的影响.方法:以三氯化铝痴呆模型小鼠为研究对象,探讨了扶元补脑冲剂对小鼠脑组织的MDA含量、Na -K ATP酶、Mg2 -ATP酶活性、脑系数及血清SOD活性的影响.结果:与模型组比较,扶元补脑冲剂能显著提高小鼠脑Na -K ATP酶、Mg2 -ATP酶及血清SOD的活性以及脑系数,降低脑MDA含量.结论:提示增强脑组织ATP酶的活性及机体抗脂质过氧化可能是扶元补脑冲剂防治老年性痴呆的作用机制之一.
