Light and electron-microscopic observations of the blood cells (haemocytes) of the stick insect Clitummus extradentatus in vitro showed that two morphologically distinct cell types, the cystocytes and granular cells are involved in haemolymph coagulation. Both these cell types contain a variable number of electron-dense granules which upon release cause progressive coagulation and precipitation of the haemolymph. In the cystocytes this release is extremely rapid (30-60s) while in the granular cells it only occurs after 1-2 min in vitro. The role of these cells in haemostasis is discussed together with the possible significance of the involvement of two cell types in the coagulation process.
对体外培养的竹节虫外齿华枝竹节虫血细胞（血淋巴细胞）进行的光学显微镜和电子显微镜观察表明，两种形态上不同的细胞类型，即囊细胞和颗粒细胞参与了血淋巴凝固过程。这两种细胞类型都含有数量不等的电子致密颗粒，这些颗粒释放后会导致血淋巴逐渐凝固和沉淀。在囊细胞中，这种释放极其迅速（30 - 60秒），而在颗粒细胞中，体外培养1 - 2分钟后才会发生释放。文中讨论了这些细胞在止血中的作用，以及两种细胞类型参与凝血过程的可能意义。
