1,6-二磷酸果糖改善兔脑血肿周围组织能量代谢的研究

目的:观察1,6二磷酸果糖(FDP)对血肿周围组织能量代谢的影响。方法:健康大耳白兔随机分成正常组,假手术组,脑出血组和治疗组,其中后3组又按各时间点分成1、6、12、24、48和72h组。两次注血法制作脑出血模型,测定各时点血肿周围组织乳酸含量、三磷酸腺苷(ATP)含量和磷酸果糖激酶(PFK)活性。结果:脑出血组24h后ATP含量有明显下降,治疗组ATP含量明显增高。1、6、12h治疗组乳酸含量降低,且治疗组乳酸峰值延迟至24h。治疗组PFK活性均高于脑出血组。结论:FDP可改善血肿周围组织的能量代谢。

Opioid peptides and receptors in joint tissues: study in the rat.

Using immunohistochemical and biochemical techniques, the occurrence of endogenous opioid peptides and their receptors in normal rat bone and joint tissues was investigated. Opioid receptors were detected, quantified, and characterized in homogenates from capsule/synovium and periosteum using radioligand binding assays. Receptor binding of the nonselective opioid [3H]naloxone to tissue homogenates was stereospecific and saturable, showing similar characteristics to that of brain tissue, although with lower binding capacities. By immunohistochemistry, the neuronal occurrence of four different enkephalins was demonstrated in synovium, bone marrow, periosteum, and juxta-articular bone, whereas no neuronal dynorphin immunoreactivity was detected. Double-staining studies disclosed that enkephalins coexisted with substance P in primary afferent fibers. The applied techniques can be used to assess changes in the distribution of endogenous opioids and their receptors in joint tissues in conditions associated with pain and inflammation. The endogenous opioid system now demonstrated might be targeted and exploited therapeutically to obtain peripheral control of symptoms in joint disorders.     

亚硒酸钠对荷Lewis肺癌小鼠癌组织和肝组织溶酶体的作用研究

用差速离心方法分离提取荷Lewis肺癌小鼠癌组织和肝组织富含溶酶体部分,并以溶酶体标志酶酸性磷酸酶(ACP)的游离酶和总酶活性比值作为观察溶酶体膜稳定性变化的指标,观察了亚硒酸钠对两种组织ACP酶活性和膜稳定性的影响。发现硒对癌组织和肝组织ACP活性的异常升高有抑制作用、稳定溶酶体膜,在癌瘤增殖前期作用明显(P<0.05)。提示这种拮抗效应与硒直接和间接的抗脂质过氧化有关。     

原发性醛固酮增多症的定位诊断与手术径路选择的初步研究——附10例报告

收治10例原发性醛固酮增多症。所有病例术前均经B超、CT扫描、血管造影及取肾上腺静脉血测醛固酮浓度4种定位方法检查。CT扫描和取肾上腺静脉血样分别获得75％和71.4％的肾上腺腺瘤诊断准确率。综合上述4种方法,7侧术前做出腺瘤定位诊断,其中5例获得术中和病理组织学证实,定位准确率为71.4％。并对手术入路的选择进行讨论,单侧腰切口仍然不能代替经腹切口。

No evidence for association between the −112G/A polymorphism of UGRP1 and childhood atopic asthma

BACKGROUND: Susceptibility to asthma is known to involve genetic factors. Genome-wide screens have indicated that the chromosome 5q31-q34 region is linked to and/or associated with asthma. A new gene, named UGRP1 and reported by Niimi et al., encodes uteroglobin-related protein and is expressed in the lung and trachea. Niimi et al. showed the -112G/A polymorphism of the UGRP1 gene to be associated with asthma in a case-control study. OBJECTIVE: The objective of the present study was to replicate this association and confirm the possible role of the UGRP1-112G/A polymorphism in the aetiology of childhood asthma in a Japanese population. METHODS AND RESULTS: We conducted a transmission disequilibrium test (TDT) in 131 families identified through paediatric patients being treated for asthma. A case-control study was also carried out by comparing the probands and 137 unrelated non-atopic non-asthmatic Japanese children and 211 unrelated healthy Japanese adults. The -112G/A polymorphism was genotyped by the PCR-RFLP method. The TDT revealed that the -112A allele was not preferentially transmitted to asthma-affected children (P=0.85). Neither the presence of at least one A allele in an individual's genotype (sum of the G/A and A/A genotypes) nor the -112A allele was more prevalent among the asthma subjects than among the control subjects. CONCLUSION: Our findings indicate that the UGRP1-112G/A polymorphism does not play a substantial role in genetic predisposition to childhood asthma in this Japanese population.
