Studies on the morphology, pathology an dreproduction of Japanese serow, special natural monument.

本课题研究期间所发表的论文归纳如下：1.形态学(1)日本种鹿肾动脉的形态学研究及肾内肾动脉的分布。(2)日本大母猪上腺和肾上腺皮质结节的形态学研究。(3)日本长羚的形态特征，特别是指间腺。(4)日本血清眶下的组织学和脂质分析，以及功能考虑。(5)臂和腰骶神经丛和脑的日本serow。2.病理(1)日本野生长角羚普遍感染副痘病。(2)日本长羚（Capricornis crispus）的病理学研究.生殖。(1)根据卵巢和胎儿的形态学对雌性日本长羚的繁殖。(2)日本长羚雄性生殖机能的季节变化。(3)野山羊肾上腺类固醇激素的合成和分泌。最重要的是，最感兴趣的是副痘病的爆发。该病在岐阜县广泛分布，发病率达39%（155/402）。结节性和丘疹性病变主要位于口鼻部、外生殖器、乳房和耳部。组织学上，病变的特点是棘层与胞浆包涵体。在气球样细胞中也证实了电子显微镜下的病毒颗粒。从生态学的观点看，趾间腺是值得注意的。腺体呈胃状盲囊，最长2.5 ~ 4cm，四足均有。在产前发育过程中，在CRL 2.5cm的早期胚胎中，该器官的原基形成为表皮起源。

Papers reported in the period of this research project were summarized as follows :1. Morphology.(1) Morphological studies on Kdneys of Japanese serows, with special reference to distribution of intrarenal artrarenal arteries. (2) Morphological studies on adreal gland and adrenal cortical nodules of Japanese serows. (3) Morphological characteristics of Japanese serow, with special reference to the interdigital glands. (4) Histology and lipid analysis of the infraorbital of Japanese serow, and functional considerations. (5) Brachial and lumbosacral plexuses and brains of the Japanese serow.2. Pathology.(1) Widespread of parapox infection in wild Japanese serows, Capricornis crispus.(2) Pathological studies on Japanese serow (Capricornis crispus).3. Reproduction.(1) Reproduction of female Japanese serow based on the morphology ovaries and fetuses.(2) Seasonal changed in male reproductive functions of Japanese serow.(3) Steroid hormone synthesis and secretion by adrenales of wild Japanese serow, Capricornis crispus.Above all, of most interest was an outbreak of parapox infection. The disease was widely distributed in Gifu Prefecture, and attained to 39% (155 out of 402 serows in incidehce. Nodular and papular lesions were mainly located in the naso-oral, external genital, udder and auricular parts. Histopathologically, the lesions were characterized by acanthosis with cytoplasmic inclusion bodies. Electron microscopically viral particles were also confirmed in balloning cells. Widespread of the disese in wild Japansese serows has never been reported.From the viewpoint of ecology, interdigital glands were remarkable. The glands were stomach-shaped blind sac, 2.5 to 4 cm in longest size, and found on all four feet. In the prenatal development, the anlage of the organ was formed as epidermal origin in early embryo of CRL 2.5 cm.
