방아깨비의 종형유충을 재료로 하여 혈구의 미세구조를 관찰한 바 4 가지의 혈구 형태를 구분해 냈다. Prohemocyte는 크기가 가장 작으며 미분화된 소기관을 가졌고 Plasmatocyte는 그 수가 비교적 많고 발달된 소기관을 가졌으며, Granular cell 은 방추형 또는 난형으로 세포질내에 몇가지 과립을 가진 것이 특징이다. Adipohemocyte는 많은 지방과립을 함유하고 microtubule 특징적으로 나타났다.
The ultrastructures of hemocytes of Acrida cinerea Thunberg were studied and 4 types of hemocytes were noticed; prohemocytes, plasmatocytes, granular cells and adipohemocytes. Prohemocytes were the smallest of all cell types with poor cytoplasmic organelles, such as endoplasmic reticulum, Golgi complexes, vacuoles and Iysosomes. Plasmatocytes were round or oval with many cytoplasmic processes, vacuoles, endoplasmic reticulum and even myelinated bodies. Granular cells were spindle-shaped or oval. In both cases, they are characterized by various granules. Adipohemocytes were very rich in lipid droplets and microtublles.
