To evaluate the interaction effects of the three chemical components, Cochinchinenin A, Cochinchinenin B and Joureirin B, of dragon's blood resin, a new method of isobologram on the basis of the Loewe Additivity was established and could analyze the interaction effect of the three drugs with variable potency rations. By using this new method we assessed the interaction characteristic of the combined inhibition effects of three chemical components of dragon's blood resin on the evoked discharges of wide dynamic range neurons of spinal cord in rats.

The results were as follows:The pituitary of Long-snout catfish included adenohypophysis and neurohypophysis. The adenohypophysis have six-cell types in common,i.e adrenocorticotro-phs,lactot-rophs,somatotrophs,gonadotrophs, thyrotrophs, and Melanotroph cells. In neurohypophysis, there were three types of neurosecretory fibres, types A1,A2 and B.There were different typesgranules in type A neurosecretory fibres axone.In type B neurosecretory fibres axone, there were many small transparent vesicles.

结果表明：长吻魷脑垂体包括腺垂体和神经垂体两个部分，腺垂体组织中有六种分泌细胞即促肾上腺皮质激素分泌细胞、催乳激素分泌细胞、生长激素分泌细胞、促性腺激素分泌细胞、促甲状腺激素分泌细胞、促黑色素细胞刺激激素分泌细胞；神经垂体组织中存在A型(A_1、A_2)和B型神经分泌纤维，A型分泌纤维轴突中具有不同类型的分泌颗粒，B型分泌纤维轴突中含有许多透明小囊泡。

Methods By a monoclonal antibody immobilization of platelet antigen assay, antiplatelet autoantibodies were detected using monoclonal antibodies specific for glycoproteins Ⅰb,Ⅱb/Ⅲa and P-selectin in patients with ITP and nonimmune thrombocytopenia. Meanwhile, RP% and PAIgG were measured in the same samples with flowcytometry.

Pyronine B adheres to on the surface of CdS and prevents CdS aggregating, which leads to the decrease of fluorescence quantum yield of CdS. Fluorescence resonance energy transfer happens from CdS to Rhodamine B, Butyl rhodamine B and Rhodamine 6G, respectively. There is a higher FRET efficiency between CdS and Neutral red with the value being 0.282. Moreover, coupling reaction between -NH_2 of Neutral red and -COOH of CdS -TGA leads to red shift of CdS fluorescence spectrum. The reaction also occurs between Safranine T and CdS. At the same time, the Fluorescence of ST is quenched by forming ST -CdS ground state complex. Chapter 6, CdS QDs modified by chitosan and polyethyleneimine can be quenched by Cu~(2+). According to the experimental result, we develop the novel sensor for Cu~(2+).

研究结果，吡啰红与CdS之间作用形式是染料聚集在CdS的表面使得CdS不易聚集，但同时也降低了CdS的发光的量子效率；罗丹明B、罗丹明6G、丁基罗丹明B均与CdS之间存在能量转移，位阻效应使得能量转移效率最高的BRhB的相对荧光强度增大最小；中性红与CdS的能量转移效率更高，同时推测可能使CdS-TGA上的-COOH与部分NR的-NH_2发生偶联导致粒子变大而发生荧光光谱的红移；番红花红与CdS是相互荧光猝灭，可能是ST的-NH_2与CdS-TGA上的-COOH发生偶联使得纳米粒子变大以及二者形成基态复合物的共同作用的影响。
