Abstract

This study is observed the skin of the parrot fish, Oplegnathus fasciatus that related study of epidermal alternation with environmental and physiological change. It composed of supporting cells, unicellular glands and accessory cells. The supporting cells are classified into superficial cell, intermediated cell and basal cell. Superficial cell of epidermal layer is squamous or cuboidal and contain nucleus of ovoid type. And its free surface has many microridge which covered with glycocalyx. Intermediated cell is ovoid and has a nucleus of round shape. Basal cell is columnar, and nucleus is situated in the upper cytoplasm. Gland cells are classified into mucous cell and club cell. By the histochemical studies of the epidermal secretions the mucous materials react on blue in ABPAS (pH 2.5). Club cell is observed numerous vacuoles and microfilaments in the cytoplasm. The cytoplasm of chloride cells are occupied with numerous mitochondria. Pigment cells are classified into two type. The one contain pigment granules of electron dense, and the other contain reflecting platelets.

돌돔의 피부는 크게 상피층과 진피층으로 구분되며, 상피층은 지지세포, 선세포 및 부속세포로 구성된다. 지지세포는 표면세포, 중간세포 및 기저세포, 선세포는 점액세포와 곤봉상세포, 그리고 부속세포는 염세포가 관찰된다. 표면세포는 편평형 또는 입방형으로서 타원형의 핵을 가지고, 미세융기(microridge)들이 발달되어 있으며 glycocalyx가 관찰된다. 중간세포는 타원형에 가깝고 원형에 가까운 핵을 가진다. 기저세포는 원주형으로서 핵은 세포질의 상부에 위치한다. 점액세포는 타원형으로 세포질은 타원형의 분비과립이 대부분을 차지하며, AB-PAS (pH 2.5)에 청색으로 반응하였다. 곤봉상세포는 세포질에 많은 액포와 미세섬유다발을 관찰할 수 있다. 부속세포인 염세포 세포질의 대부분이 미토콘드리아로 가득 채워져 있다. 색소세포는 세포질에 전자밀도가 높은 색소과립들을 함유한 종류와 반사소판을 함유한 종류로 구분된다.
