At necropsy, two animals had atrophy of the pancreas, whereas other visceral organs, including the endocrine organs, showed no significant changes. Microscopically, there was atrophy and reduced numbers of pancreatic islets accompanied by interlobular and interacinar fibrosis and compensatory enlargement of some remaining islets. Lymphocytes were observed commonly around and within atrophic islets and occasionally around and within enlarged islets. Vacuolar degeneration with occasional accumulation of glycogen granules was observed in the \u03b2-cells of these enlarged islets. Immunohistochemical studies of atrophic islets demonstrated complete loss of \u03b2-cells or only a few small \u03b2-cells. There also was a corresponding decrease in the number of cells that stained with anti-glucagon (\u03b1-cells) or anti-somatostatin (\u03b4-cells) antibodies. The vacuolated cells in the enlarged islets stained strongly with anti-insulin antibody (\u03b2-cells). Ultrastructurally, the majority of cells in the atrophic islets had reduced cytoplasmic volume and few secretory granules, features consistent with \u03b1-cells. In contrast, enlarged islets that had prominent immunohistochemical staining for insulin (\u03b2-cells) consisted of \u03b2-cells with cytosolic edema, mitochondrial swelling, dilated smooth endoplasmic reticulum, and reduced numbers of or degranulated secretory granules. These pathomorphologic features found in cattle are similar to those found in juvenile-onset insulin-dependent diabetes mellitus in human beings and suggest autoimmune involvement in diabetes.<\/jats:p>","DOI":"10.1177\/030098589303000106","type":"journal-article","created":{"date-parts":[[2010,3,8]],"date-time":"2010-03-08T17:19:33Z","timestamp":1268068773000},"page":"46-54","source":"Crossref","is-referenced-by-count":19,"title":["Spontaneous Diabetes Mellitus in Young Cattle: Histologic, Immunohistochemical, and Electron Microscopic Studies of the Islets of Langerhans"],"prefix":"10.1177","volume":"30","author":[{"given":"H.","family":"Taniyama","sequence":"first","affiliation":[{"name":"Department of Veterinary Pathology, Rakuno Gakuen University, Ebetsu, Hokkaido, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"T.","family":"Shirakawa","sequence":"additional","affiliation":[{"name":"Department of Veterinary Pathology, Obihiro University of Agriculture and Veterinary Medicine, Obihiro, Hokkaido, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"H.","family":"Furuoka","sequence":"additional","affiliation":[{"name":"Department of Veterinary Pathology, Obihiro University of Agriculture and Veterinary Medicine, Obihiro, Hokkaido, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S.","family":"Osame","sequence":"additional","affiliation":[{"name":"Department of Veterinary Pathology, Obihiro University of Agriculture and Veterinary Medicine, Obihiro, Hokkaido, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"N.","family":"Kitamura","sequence":"additional","affiliation":[{"name":"Department of Veterinary Pathology, Obihiro University of Agriculture and Veterinary Medicine, Obihiro, Hokkaido, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"K.","family":"Miyazawa","sequence":"additional","affiliation":[{"name":"Department of Veterinary Pathology, Obihiro University of Agriculture and Veterinary Medicine, Obihiro, Hokkaido, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[1993,1,1]]},"reference":[{"key":"bibr1-030098589303000106","first-page":"S328","volume":"5","author":"Baker JS","year":"1983","journal-title":"Compend Cont Ed Pract Vet"},{"key":"bibr2-030098589303000106","first-page":"97","volume":"79","author":"Baker LH","year":"1931","journal-title":"J Am Vet Med Assoc"},{"key":"bibr3-030098589303000106","first-page":"99","volume":"67","author":"Biester HE","year":"1925","journal-title":"J Am Vet Med Assoc"},{"key":"bibr4-030098589303000106","first-page":"387","volume":"65","author":"Bommer G","year":"1981","journal-title":"Verh Dtsch Ges Pathol"},{"key":"bibr5-030098589303000106","first-page":"863","volume":"2","author":"Christensen NO","year":"1950","journal-title":"Nord Vet Med"},{"key":"bibr6-030098589303000106","first-page":"287","volume":"74","author":"Craighead JE","year":"1974","journal-title":"Am J Pathol"},{"key":"bibr7-030098589303000106","doi-asserted-by":"publisher","DOI":"10.1093\/oxfordjournals.bmb.a071513"},{"key":"bibr8-030098589303000106","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2265.1973.tb00425.x"},{"key":"bibr9-030098589303000106","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-642-65684-2_2"},{"key":"bibr10-030098589303000106","doi-asserted-by":"publisher","DOI":"10.2337\/diab.27.1.S251"},{"key":"bibr11-030098589303000106","first-page":"237","volume":"14","author":"Goldner J","year":"1938","journal-title":"Am J Pathol"},{"key":"bibr12-030098589303000106","doi-asserted-by":"publisher","DOI":"10.1136\/vr.109.24.539"},{"key":"bibr13-030098589303000106","doi-asserted-by":"publisher","DOI":"10.1016\/S0046-8177(80)80030-X"},{"key":"bibr14-030098589303000106","first-page":"699","volume":"85","author":"Junker K","year":"1977","journal-title":"Acta Pathol Microbiol Scand A"},{"key":"bibr15-030098589303000106","first-page":"367","volume":"144","author":"Kaneko JJ","year":"1964","journal-title":"J Am Vet Med Assoc"},{"key":"bibr16-030098589303000106","first-page":"154","volume-title":"Pancreatic Pathology","author":"Kl\u00f6ppel G","year":"1984"},{"key":"bibr17-030098589303000106","doi-asserted-by":"publisher","DOI":"10.1126\/science.1105788"},{"key":"bibr18-030098589303000106","doi-asserted-by":"publisher","DOI":"10.1080\/01652176.1982.9693853"},{"key":"bibr19-030098589303000106","first-page":"24","volume":"67","author":"Mostaghni K","year":"1977","journal-title":"Cornell Vet"},{"key":"bibr20-030098589303000106","first-page":"114","volume":"61","author":"Phillips RW","year":"1971","journal-title":"Cornell Vet"},{"key":"bibr21-030098589303000106","unstructured":"Sternberger LA: Immunocytochemistry, 2nd ed., pp. 104\u2013159.
