血竭

Through the analysis of the contents of loureirins of the zymolysis products of fungus with different culture time, it can conclude that dragon's blood is the products of interactions between Dracaena cochinchinenis and the animalcula.

对比部分微生物不同培养时间的发酵产物，可以得出龙血竭的形成是剑叶龙血树和它损伤后感染的微生物相互作用的结果，并且从微生物回接实验的结果来看，某些微生物对剑叶龙血树龙血竭的形成有一定的促进作用。

In chapter 3, the animalcula of Dracaena cochinchinenis's wound were carefully isolated, it also argues the effect of fungi on the formation of the dragon's blood. Moreover, the loureirins of the liquid zymolysis products of some fungi were detected by HPLC, and the relationship between animalcula and the formation of the dragon's blood is further discussed.

第三章详细地论述了剑叶龙血树微生物群的分离、纯化及其对龙血竭形成的影响，并用HPLC对部分微生物的液体发酵产物作龙血素成分的检测，更进一步地了解微生物与剑叶龙血树龙血竭形成的关系。

It is excreted from the dracaena plant's xylem after the xylem was injured by the outside force or intruded by the epiphyte, so it gains the recognition of the holy medicine on activating blood circulation.

血竭为一种传统名贵中药，它是龙血树属植物的木质部在受外力损伤或遭真菌侵入后分泌的红色树脂，被称为"龙血"，内服具有活血化淤、止痛等作用，外用具有生肌、止血、敛疮的功效，有"活血之圣药"的美誉。

The analysis of the chemical constitutes among sterns roots and leaves of Dracaena cochinchinenis, showed that there' s small amount loureirin A in their extracts, with 0.053mg/g, 0.058mg/g, 0.015mg/g respectively only. Therefore, the roots, stems and leaves of Dracaena cochinchinenis have too low contents of loureirins to be raw materials of dragon's blood.

分析剑叶龙血树根、茎、叶的成分，发现风干的剑叶龙血树根、茎、叶中没有龙血素B的存在，只含有少量的龙血素A，其含量在根、茎、叶中分别为：0.058mg/g，0.053mg/g，0.015mg/g，其含量远低于现行的龙血竭中龙血素A含量不低于2％的质检标准，因此剑叶龙血树的根、茎、叶不能直接用作生产龙血竭的原料。

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.

为了评估龙血竭的3种化学成分剑叶龙血素A、剑叶龙血素B和龙血素B在活体动物实验中的相互作用特性，从经典的Loewe Additivity模型中推导出了在效价强度比变化的情况下判断3种药物的相互作用性质的等效图分析方法，以此分析了龙血竭的上述3种化学成分联合抑制大鼠脊髓背角广动力范围神经元诱发放电频率时的相互作用类型。

Methods Dracorhodin and bletilla striata were compounded into enema for the preparation of treatment, which was then administered to 51 patients of UC for six months. Oral sulfasalazine (1.5 g per day) were meanwhile given to another group of patients. The curative effects were evaluated by comparing the recurrence rates and the side-effects between the two groups.

以血竭、白芨为原料制备复方血竭灌肠液，对51例UC患者进行灌肠治疗6个月；SASP组给予SASP 1.5 g 1次/d 口服维持6个月，比较两组患者的复发率及治疗中的副作用。

In hypoxia/reoxygenation model(Na2S2O4), cell survival was enhanced and LDH in culture medium was reduced(P.05, P.01) after treated with 60, 30μgmL^(-1) Sanguis Draconis flavones. Enhanced cell survival and reduced LDH in culture medium(P.05, P.01) also observed in cytotoxicity model induced by H2O2 after incubated with 60, 30, 15μgmL^(-1) Sanguis Draconis flavones.

在缺氧／复氧(Na2S2O4)模型中，60、30μgmL^(-1)龙血竭总黄酮能显著降低培养液中的LDH浓度，增强细胞活力(P.05， P.01)。60、30、15μgmL^(-1)龙血竭总黄酮能抑制H2O2引起的损伤，降低培养液中LDH的浓度，增强受损细胞活力(P.05， P.01)。

Dragon bloods from China and abroad have some effects on promoting blood circulation,removing blood stasis and anti-thrombosis.

国产血竭和进口血竭均有一定的活血化瘀和抗血栓形成的作用。

In chapter 4, for the further study on dragon's blood, the ecological mechanism of the formation of dragon's blood was tentatively analyzed.

第四章在前人的研究成果基础上结合本实验结果，初步分析了真菌与剑叶龙血树龙血竭形成的相互作用关系，试图为进一步解释龙血竭的形成提出可能的实验依据。

Objective: To study the cyclodextrin inclusion complexes of Dragon's blood for improving the drug solubility and the preparation.

摘要目的：运用环糊精包合作用，提高龙血竭的溶解度，研制龙血竭片剂。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.
