马氏管

家蚕马氏管组织构造的研究

Studies on the Shape and Stucture of Malpighian Tubules in the Silkworm

生殖腺开口于近腹部基部，排泄器官通常为马氏管。

The gonads open near the base of the abdomen and the excretory organs are usually Malpighian tubules .

在家蚕头部、消化道、马氏管、丝腺、卵巢、精巢中，两种ace基因均有表达，并且两种基因在不同的组织中表达量存在差异。

In the insect head , enteron , Malpighian tubules , silk gland , ovary , testis , the two ace-specific expressions of both genes are different , indicating its function differences .

12h肠壁细胞、马氏管和卵巢均出现阳性反应，蚊围食膜开始出现，但不完整；

12 h , stronger reactions were distributing in the midgut wall , ovary , malpighian tubule , the peritrophic matrix ( PM ) began to appear ;

棉铃虫消化系统及马氏管的解剖学研究

Study on anatomy of the digestive system and Malpighian tubule of Helicoverpa armigera

脂肪体在表皮下广泛分布，马氏管外形不规则及管腔狭窄等病理变化。

Fat body widely distributed under the epidermis and the shape of malpighian tubes was abnormal and its lumens narrowed .

70%的产孢量是从幼虫丝腺、马氏管和唾腺获得的。

About 70 % of the propagated spores was obtained from the silk glands , Malpighian tubles and salivary glands of the host .

在光镜下观察，α-T对白纹伊蚊幼虫的靶标是中肠、马氏管和脂肪体。

The observation with light microscope showed that the targets of alpha-terthienyl to Aedes albopictus larvae were midgut , malpighian tubule and fat body .

翻译量也以精巢为最高，其次是头、中肠和马氏管。

However , the highest translation level was found in testis , and then was in head , midgut , and malpighian tubules , respectively .

扫描电镜和透射电镜下观察α-T作用后白纹伊蚊幼虫中肠和马氏管的超微结构的改变。

To observe the ultrastructure changes of Aedes albopictus larvae in midgut microvilli , midgut cell , malpighian tubule with electron microscopes ( SEM and TEM ) .

成虫马氏管细胞主要有二种类型，即大型的基本细胞和小型的底细胞，前者为主，后者数量较少。

In adult Malpighian tubule the cells are similar to those of the larvae , but can only be distinguished as two types including the large primary cells and the small basal cells .

观察到脂肪体、消化道、马氏管、肌肉组织的感染症状，以及真菌对幼虫丝腺腔中的丝胶层和液体丝素的侵染和占据过程。

Infection symptoms were observed in the fat body , alimentary canal , the Malpighian tubules and the muscle tissue . The fungus attacked and colonized the sericin layer and the liquid fibroin in the silk gland lumen .
