《维摩诘经》之维摩诘形象的现代解读

《维摩诘经》中的维摩诘是一位卓越的大乘佛教的导师和宣传家,他通达大乘佛法精义,其所说佛法精义主要包括:一是"缘起性空、法性无住",二是"不二法门"。他的理想追求是"引渡众生"。维摩诘这一富于理想色彩的美好形象千百年来一直成为中国居士佛教信仰的典范,给中国文学及其它艺术带来了广泛而深远的影响。     

鲍壳表层绿色物质的初步研究

主要介绍了用吸收光谱法研究鲍壳表层绿色物质水解液的性质，并用活性炭、高岭土和离子交换树脂吸附的方法对鲍壳表层绿色物质进行了分离的尝试，实验结果显示：该水解液可见光吸收光谱吸收峰位于610nm波长处，用紫外分光光度法测出在204nm和209nm两处有吸收峰，与藻蓝蛋白的光谱图较为相似,用阳离子交换树脂可以将该绿色物质成功分离出来。     

Endorcine cells producing regulatory peptides

Summary Recent data on the immunologication of regulatory peptides and related propeptide sequences in endocrine cells and tumours of the gastrointestinal tract pancreas, lung, thyroid, pituitary (ACTH and opioids), adrenals and paraganglia have been revised and discussed. Gastrin, xenopsin, cholecystokinin (CCK), somatostatin, motilin, secretin, GIP (gastric inhibitory beenrevised and discussed. Gastrin, xenopsin, cholecystokinin (CCK), somatostatin, motilin, secretin, GIP (gastric inhibitory polypeptide), neurotensin, glicentin/glucagon-37 and PYY (peptide tyrosine tyrosine) are the main products of gastrointestinal endocrine cells; glucagon, CRF (corticotropin releasing factor), somatostatin, PP (pancreatic polypeptide) and GRF (growth hormone releasing factor), in addition to insulin, are produced in pancreatic islet cells; bombesin-related peptidesare the main markers of pulmonary endocrine cells; calcitonin and CGRP (calcitonin gene-related peptide) occur in thyroid and extrathyroid C cells; ACTH and endorphins in anterior and intermediate lobe pituitary cells, -MSH and CLIP (corticotropoin-like intermediate lobe peptide) in intermediate lobe cells; met- and leu-enkephalins and related peptides in adrenal medullary and paraganglionic cells as well as in some gut (enterochromaffin) cells; NPY (neuropeptide Y) in adrenalin-type adrenal medullary cells, etc.. Both tissue-appropriate and tissue-inappropriate regulatory peptides are produced by endocrine tumours, with inappropriate peptides mostly produced by malignant tumours.     

P物质对大鼠星状神经节细胞的影响

应用细胞内生物电记录方法，观察神经肽Ｐ物质（ＳＰ）对大鼠星状神经节能细胞的影响，用灌流或用加压向细胞周围施加ＳＰ可使部分细胞发生膜除极反应，用低钙或用含河豚毒素克氏液灌流神经节，并不影响ＳＰ引起的除极反应的幅度和时程。ＳＰ引起除极反应的同时常伴有膜电阻增大，当膜电位增大时，除极化反应幅度变小，反转电位为－８０ｍＶ至－１００ｍＶ，研究表明，ＳＰ对部分星状神经节细胞具有直接兴奋作用，并且ＳＰ对细胞膜的     

服装消费与环保

Depolarization Induced by Substance P on Rat Stellate Ganglion Neurons

应用细胞内生物电记录技术，观察神经肽Ｐ物质（ＳＰ）对大鼠星状神经节细胞的影响。ＳＰ在１μｍｏｌ～１０μｍｏｌ或更高的浓度范围内，供试３５个细胞，有２８个细胞发生膜除极反应。用低钙（０．２５ｍｍ）或用含河豚毒素（ＴＴＸ，１μｍｏｌ）克氏液灌流神经节，不影响ＳＰ引起的除极反应的幅度和时程。ＳＰ引起除极反应的同时常伴有膜电阻增大。当膜电位增大时，除极化反应幅度变小，反转电位为－８０ｍＶ至－１００ｍＶ。研究表明，ＳＰ对部分星状神经节细胞具有兴奋作用，使通过这些细胞的信息传递增强；ＳＰ对细胞膜的除极作用是由于其引起细胞膜钾导降低所致。     

区域观测与地理实在

Ultrastructural localisation of substance P and choline acetyltransferase in endothelial cells of rat coronary artery and release of substance P and acetylcholine during hypoxia

Substance P and choline acetyltransferase have been localised in a small proportion of endothelial cells of rat coronary arteries using electron microscopic immunocytochemistry. During a hypoxic period of 1 min, coronary vasodilatation was produced in the Langendorff heart preparation and increased levels of substance P and acetylcholine were released into the perfusate. The possibility that these substances are released from endothelial cells during hypoxia and contribute to the hyperaemic response is discussed.     

三种脑-肠肽对人绒毛膜促性腺激素分泌的影响

本工作利用灌流技术观察了3种脑-肠肽(P物质,CCK及NT)对新鲜人工流产的绒毛hCG分泌的影响。结果表明,P物质,CCK及NT均明显刺激绒毛释放hCG,并发现CCK作用大于P物质及NT。提示,hCG的分泌可能受这3种脑-肠肽的调节。     

有关北京学的几点思考

建立北京学是客观需要，分别研究北京的方方面面，都不称其为北京学，真正的北京学应当是在这些分别研究的基础上升华形成的能够揭示有关北京各方面更深层次奥秘的科学理论体系。加强北京学的基础理论研究，广泛深入地开展北京学的应用研究，重视对北京学的宣传工作和加强北京联合大学北京学研究所科研条件和科研队伍的建设，是今后北京学发展的主要方向和任务。
