芫菁素

To determine the contents and the existing form of cantharidin in Meloidae.

测定芫菁体内斑蝥素的含量及其存在形式。

And the mol of Ca element in Mylabris was lower than that of the bound cantharidin.

斑芫菁属昆虫体内钙元素的摩尔量要低于结合斑蝥素的摩尔量。

Histological characteristics of reproductive gland,were described and its relations to the cantharidin stored and transferred within or between the adults were discussed.

对大斑芫菁生殖腺组织学特征进行了描述，并就它与芫菁素在虫体内和虫体间的贮存和运转关系进行了讨

The study on soluble protein after eclosion when cantharidin synthesis is active in Mylabris calida Palla would help to clarify the synthesis mechanism of cantharidin and involved enzymes of the synthesis.

研究斑蝥素大量合成期的芫菁体内可溶性蛋白，有助于阐明斑蝥素合成相关酶蛋白的种类和合成机理。

Methods The total cantharidin obtained with acidolysis method and the free cantharidin obtained with direct extraction method were determined in eight species of Meloidae and the control species Huechys sanguinea (Homoptera: Cicadidae) by gas chromatography, and the content of the bound cantharidin in each species was calculated with the content difference between the total cantharidin and the free cantharidin. The relationship between the contents of the bound cantharidin and the contents of Ca and Mg elements in Meloidae were assessed.

利用气相色谱法测定了8种芫菁和作为对照的黑翅红蝉体内总斑蝥素和游离斑蝥素的含量，总斑蝥素含量是通过酸水解法测得的，游离斑蝥素含量是通过直接浸提法测得的，以总斑蝥素与游离斑蝥素含量之差作为结合斑蝥素含量；并比较了结合斑蝥素与钙、镁含量之间的相关性。

The contents of the total cantharidin were higher than the contents of the free cantharidin in Meloidae. The bound cantharidin may exist in the forms of magnesium cantharidate and calcium cantharidate.

芫菁体内总斑蝥素含量远高于游离斑蝥素的含量；结合斑蝥素可能是以斑蝥素酸钙和斑蝥素酸镁形式存在。

Positive relationship was found between the bound cantharidin and Ca element in Mylabris and Epicauta, and between the bound cantharidin and Mg element in Mylabris, but negative relationship was found between the bound canthaiidin and Mg element in Epicauta.

斑芫菁属和豆芫菁属昆虫中的结合斑蝥素含量与钙元素呈正相关，斑芫菁属中结合斑蝥素含量与镁元素呈正相关，而豆芫菁属中结合斑蝥素含量与镁元素呈负相关。

The adult reproductive system of Epicauta mannerheimi and Mylabris phalerata were dissected and a histological study was made on the reproductive gland of Myllabris phalirata .

芫菁为鞘翅目芫菁科昆虫，其成虫和幼虫体内均含有一种倍半萜烯毒素——芫菁素 [1] ，因芫菁素不仅可以医治多种癌症，还可升高人体白血球，而成为一种重要的药用昆虫。

Histological characteristics of reproductive gland,were described and its relations to the cantharidin stored and transferred within or between the adults were discussed. Epicauta mannerheimi ; Mylabris phalerata ; reproductive gland ; histological characteristics ; cantharidin

作者在进行两种芫菁生殖腺解剖后，又初步探究大斑芫菁生殖腺的组织学特征，目的在于为芫菁的精子贮存、运送、授精、芫菁素传递等过程提供初步理论依据。1 材料和方法1 。1 材料细纹豆芫菁于 1 999年 6月中旬采自福州市郊高

Results The results showed that the total cantharidin contents in the samples of Meloidae were 1 to 9 times the free cantharidin contents. The total cantharidin contents were generally higher than 2.0% of dry body weight and the free cantharidin contents were all less than 1.7% of dry body weight in Mcloidac.

芫菁体内总斑蝥素的含量为游离斑蝥素含量的1-9倍，总斑蝥素的含量一般多于虫体干重的2.0%，而游离斑蝥素的含量均低于虫体干重的1.7%。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
