芦荟凝集素提取及促免疫活性功能初步研究

分别从3种有经济价值的芦荟品种,即中华芦荟（Aloe vera .ver.chinensis(Haw））,库拉索芦荟（Aloe barbadensis Mill)和木立芦荟（Aloe arborescens Mill)中采用凝胶层析法提取了3种凝集素,Lecl,Lec2和Lec3,经过聚丙烯酰胺凝胶电泳分析其为单一成分的糖蛋白,比较了3种凝集素的糖和蛋白的含量,得出库拉索芦荟凝集素Lec2糖含量最高,木立芦荟凝集素Lec3蛋白含量最高,免疫学实验证明,库拉索芦荟凝集素的凝集效价最高,其次为木立芦荟,中华芦荟,3种凝集素对淋巴细胞转化功能都有明显的促进作用,其中库拉索芦荟凝集素Lec2的促淋巴细胞转化率最高,因此芦荟凝集素在治疗免疫功能低下方面可能有一定的应用价值。     

中华眼镜蛇毒灌胃后的兔血清对人肺腺癌细胞株的影响

目的：了解中华眼镜蛇毒灌胃后的兔血清对人肺腺癌细胞的影响。方法：采用体外细胞培养的方法,观察蛇毒灌胃后的兔血清对人肺腺癌细胞及人胚肺成纤维细胞的细胞毒作用,对细胞生长及分裂数的影响。结果：蛇毒灌胃后的兔血清能够明显抑制肺腺癌细胞的生长,且其抑制效应随剂量的增加而增加,但该血清对正常人胚肺成纤维细胞的生长却没有明显影响。结论：中华眼镜蛇毒灌胃后的兔血清对肺腺癌细胞的生长有明显的抑制作用,且有高度的选择性。

内蒙古典型草原金龟总科昆虫幼虫群落动态及对放牧的响应

内蒙古典型草原金龟总科昆虫幼群落组成以东方绢金龟和弓斑常丽金龟为优势种,在两种主要植物群落类型大针茅草原和羊草草原中无明显差异。金龟总科昆虫幼虫的季节动态在０这两类草原均表现为春季和秋季密度较高,而夏季密度较低,在土壤中的垂直分布式随季节的变化而变化。金龟总科昆虫幼虫群落对长期持续放牧扰动的响应主要表现为密度降低,特别是东方绢金龟种群密度降低。     

新型抗肝片吸虫病药物化合物HBSA-CO1的合成及解偶联活性研究

合成了邻羟基苯磺酰苯胺类药物化合物：Ｎ－（２,５－二甲基－４－本甲酰基）苯基－２－羟基－３,５,６－三氯苯磺酰胺,并对该药物化合物进行了结构表征。采用氧电极法、测呼吸过程中磷的变化以及测ＡＴＰ酶活性等方法研究其对线粒体氧化磷酸化反应的解偶联作用,结果表明,ＨＢＳＡ－ＣＯ１化合物是较好的解偶联剂,其偶联活性高于Ｎ－（２,４,５－三氯）苯基－２羟基－（３,５,６－三氯）本磺酰胺化合和ＤＮＰ。因此,根据

甲基葡萄糖苷钻井液研究

以廉价的淀粉代替葡萄糖作为主要原料,直接与甲醇反应合成了甲基葡萄糖苷（MEG）,并对合成样品的部分理化性能、在粘土上的吸附规律、生物降解特性以及对岩心半透膜效率的影响规律等进行了测定。用合成的甲基葡萄糖苷配制了淡水、盐水和饱和盐水3种钻井液配方,并对3种配方的常规性能、高温性能、抗污染性能和活度进行了室内评价。结果表明,用淀粉合成的甲基葡萄糖苷,在理化性能上与用葡萄糖帛备的试剂样品接近,用其配制成的钻井液具有活度低、高温稳定性好,流变性易调整和抗污染能力强等特点,且具有改善页岩膜效率的作用,无毒,易生物降解,是理想的环保型钻井液体系。     

Mechanism for chronic pain generation

Neuropathic pain and the other abnormalities of sensation induced by axon injury or by peripheral nerve inflammation should result from functional compensations of the injured neurons during their regeneration. Ectopic distribution of proteins related to Na⁺, K⁺ and Ca²⁺ channels as well as of receptors on both membranes of injured axon and its cell body becomes a main pacemaker from which spontaneous ectopic afferent of primary sensatory neurons and crosstalk between neurons occur. Abnormal ectopic afferent activities lead to disorders of the sensation, such as hyperalgesia, allodynia, spontaneous pain and paraesthesia. Administration of some ion channel agents and/or α2-adrenergic blockers has shown efficiency in preventing neuropathic pain development and in relieving neuropathic pain.     

The nature of the solar activity during the Maunder Minimum revealed by the Guliya ice core record

Whether the solar activity was very low, and especially whether the solar cycle existed, during the Maunder Minimum (1645–1715 AD), have been disputed for a long time. In this paper we use the Guliya NO₃ ⁻ data, which can reflect the solar activity, to analyze the characteristics of the solar activity during the Maunder Minimum. The results show that the solar activity was indeed low, and solar cycle displayed normal as present, i.e. about 11a, in that period. Moreover, it was found that the solar activity contains a 36-year periodic component probably, which might be related to the variations in the length of the sunspot cycle. This finding is of importance for the study of the relationship between the sun variability and the Earth climate change.
