鷄痘毒과 鳩痘毒에 依한 鷄胎兒脈絡尿膜(CAM)病變의 病理組織學的硏究
林昌亨 서울대학교 1965 서울대학교 論文集 Vol.16 No.-
Minnesota strain of pigeon-pox virus and 2755 strain of fowl-pox virus were inoculated on the chorio-allantoic membrane(CAM) of 12 day-old chick embryos. The eggs were incubated for 120 and 96 hours respectively, after virus inoculation, and the infected CAM was collected. 1. Grossly, the pocks produced by fowl-pox virus were light brown in color and flat in appearance. The vascular nets of CAM were moderately congested and some hemorrhagic spots on the pocks were observed. The pocks produced by pigeon-pox virus were pearly white in color and elevated above the CAM surface. The vascular nets of CAM were shown severe congestion and numerous small vesicles were formed on the pocks. 2. Microscopically, both sections of pocks produced by fowl and pigeon-pox viruses showed a number of the alterative changes in 3 germ layers. On the ectodermal cells, hyperplasia and hypertrophy accompanying with the vacuolization and necrosis were observed. Keratinization in the ectodermal surface, formed on the pocks by pigeon-pox virus, was more marked than that of fowl-pox virus. In the mesoderm, pegeon-pox virus produced more marked edema, cellular infiltration, focal necrosis and increased fibrous tissue cells which caused to thicken the layer than those occurring in fowl-pox virus lesions. Many epithelial nodules were noted in the lesions of fowl-pox virus exclusively. On the entodermal cells, hyperplasia and hypertrophy accompanying with vacuolization, and frequently, papillary projections of hyperplastic entodermal layer were observed. In the both cases, the Bollinger bodies were readily demonstrable in the areas of vacolization of the hyperplastic ectodermal and entodermal layers.

Normal Albino rats were received glycerin via subcutaneously and Staphylococcus aureus intravenously. The microorganism was coagulase-positive and non-hemolytic. The rats received glycerin alone showed an acute tubular nephrosis, and the others such as glycer in induced nephrotic rats showed a number of different findings: At the first hours of the bacterial injection, in medulla, the bacterial clumps and inflammatory cell infiltration, and microabscesses with retrogressive changes of proximal convoluted tubulles were observed. The suppurative inflammation was observed in days. Five weeks after the initial innoulation of the organism kidney was shown restoration to a histologically normal cortex. The proliferation of fibrous connective tissue and small numbers of chronic inflammatory cells were observed in the medulla where an acute inflammatory process was enhanced presumably. On the other hand, the Albino rats administered Staphyloceccus aureus alone resulted in n moderate degree of vacuolization in proximal convoluted tubules and a number of casts in the early stage. No, bacterial clumps and microabscesses were observed in the rats.

Nineteen cases of Albino rat having naturally occurred renal lesions were observed during the routine examination of a total of 240 cases. The lesions observed were focal suppurative nephritis (6 cases), acute nonsuppurative nephritis (3 cases), chronic interstitial nephritis (4 cases), nematode infection in pelvic epithelium (5 cases, in which one case was coincident with focal suppurative nephritis) and unilateral hydronephrosis (2 cases). Gross and microscopic findings for the lesions were described and discussed.

Pseudomembranous enteritis has been observed sporadically in milk cow since fall of 1967. The pseudomembrane molded in intestinal lumen was sloughed off as a hollow cylindrical casts which were evacuated with the intestinal contents. The cylindrical casts measuring 1.5-2.0 ㎝ in diameter, 0.3-0.5 ㎝ in thickness, and up to 1 m in length were greyish-brown or greyish yellow in color and friable in consistency. Histological examination showed that the pseudomembrane was consisted of fibers of fibrin forming strands or meshes in which small quantity of mucus was present. Many degenerative and necrotic neutrophils accompanied with some of coccoid and basophilic bacterial colonies were also present in the outer part of the membrane. The animals were generally recovered after the evacuation of the cast per anum. Adequate treatment at the onset of disease has been considered effective in minimizing the damage.
