人血清中IgE含量随年龄增长的改变及临床意义

IgE是反应素型抗体,血清中浓度很低,在体内与嗜碱细胞或肥大细胞表面的IgE受结合.对不同年龄组正常人进行血清IgE检查,发现随年龄增加,IgE含量有增高趋势,并且随年龄增高亦有过敏性疾病多发的趋势.吸烟数量过多、时间长亦可使IgE增高.

目的 :观察血清保存方法对促甲状腺激素 (TSH)结果的影响。方法 :将甲状腺功能正常、异常患者共 10份血清 ,采用不同血清量、不同条件分组保存后测定 TSH。结果 :保存方法对 TSH结果有一定的影响。结论 :用于 TSH血清的保存量要多、要密封管口、低温保存。     

羊心淋巴流阻断后血清生化指标的改变

为给临床心脏术后监测心淋巴管损伤程度及可能出现的并发症提供参考指标，以手术方法阻断羊心淋巴流并对其血清相关成份进行了测定。实验发现，实验组术后谷草转氨酶（ＳＧＯＴ）、谷丙转氨酶（ＳＧＰＴ）、碱性磷酸酶（ＡＫＰ）、乳酸脱氢酶（ＬＤＨ）均有不同程度的增高，以ＳＧＯＴ增高最为明显，术前均值为４７．５３Ｕ，术后２天增至１０４．２０Ｕ，高峰出现时间最早，多在术后２４小时。血清离子改变中低钾最为突出，血钾在术后２天明显降低（Ｐ＜０．０１），术后７天逐渐恢复，术后１４天恢复至术前水平。血清蛋白改变以球蛋白降低、白蛋白／球蛋白比值升高为主。提示心淋巴循环郁滞可导致心肌细胞损伤、毛细血管通透性和结构的改变。不同酶活性的变化对郁滞的敏感度存在着差异。     

脑血管病患者血清IgE型免疫复合物的检测

本文用胶固素酶联免疫吸附试验检测了１６例缺血性脑血管病（ＩＣＤ）患者，１４例出血性脑血管病（ＨＣＤ）患者和２０例健康正常人的血清ＩｇＥ型循环免疫复合物（ＣＩＤ）水平。结果显示ＩＣＤ组和ＨＣＤ组ＩｇＥ－ＣＩＣ水平明显高于正常组（分别为Ｐ＜０．００１和Ｐ＜０．０５）。ＩＣＤ组与ＨＣＤ组间没有显著差异（Ｐ＞０．０２）。提示脑血管病的发生与ＩｇＥ－ＣＩＣ的形成有关。     

Serum levels and clinical response in long-term pharmacotherapy with zuclopenthixol decanoate

Twenty-six patients diagnosed as chronic schizophrenics were given injections of zuclopenthixol decanoate (cis(Z)-clopenthixol decanoate) 200 mg every 3 weeks for at least 6 months. Before treatment and on each day of injection the patients' mental state was assessed by Brief Psychiatric Rating Scale (BPRS), 18 items. A registration of side effects and basal laboratory data was also performed. Blood samples were drawn on each day of injection before injection and 3–7 days after injection (time of maximum concentration). Neuroleptic activity, which was considered equivalent to the concentration of zuclopenthixol, was determined in serum by radio-receptor assay (RRA). Based on amelioration scores ≥50% on the BPRS, 15 patients were characterized as responders and 11 as non-responders. The responder group showed a statistically significant reduction in BPRS score, whereas this was not the case for the non-responders. Apart from a few patients, the serum concentrations showed a low intra-individual variation, but a relatively high inter-individual variation. The responder group had a significantly higher mean preinjection concentration than the non-responder group, whereas no significant difference was found in day 3–7 concentrations. The fluctuation of the serum concentration expressed as the ratio between maximum (days 3–7) and minimum (pre-inj.) was found to be significantly lower for responders than for non-responders. Thus although the present study did not demonstrate a clear relationship between serum level and clinical effect, it indicates that the best antipsychotic effect is obtained with a serum concentration which fluctuates only slightly (the ratio max/min concentration not exceeding 2.1).
