The salivary glands in female H. dromedarii consists of three alveolar types, one agranular (type I) and two granular (type II and III). Five granule secreting cell types were identified according to their granular submicroscopic appearance. The structure and changes observed in type I alveoli before, during and after feeding suggest its role in ion and water transport from the haemolymph to the lumen during initial feeding. Secretory cells in salivary alveoli types II and III undergo substantial growth, differentiation and accumulation of secretory material during feeding and various rates of depletion directly after feeding. Attachment and limited feeding seems to provide a stimulus for synthesis of proteins, lipids and carbohydrates, whereas detachment from the host decreases the secretory competence of these alveoli causing its degeneration.
雌性单峰驼唾液腺由三种腺泡类型组成,一种无颗粒型(I型)和两种颗粒型(II型和III型)。根据颗粒的亚显微外观鉴定出五种颗粒分泌细胞类型。在进食前、进食期间和进食后观察到的I型腺泡的结构和变化表明,其在进食初期从血淋巴向管腔转运离子和水的过程中发挥作用。II型和III型唾液腺泡中的分泌细胞在进食期间经历大量生长、分化和分泌物质积累,并在进食后直接以不同速率消耗。附着和有限进食似乎为蛋白质、脂质和碳水化合物的合成提供了刺激,而与宿主分离会降低这些腺泡的分泌能力,导致其退化。
