Hard Tissue Lesions Associated with Malnutrition

The hard tissues, bone, cartilage and teeth, are very sensitive to improper nutrition and react very quickly to even minor variations in the ration. Not only are these reactions distinct but often they appear early in the course of an illness. Frequently they are an indelible imprint of the experience and persist for the entire life of the animal

Classification of Lung Lesions

The classification of lung lesions according to location is a system that enables one to diagnose lung diseases on gross examination. In most instances it also indicates the probable etiology. The schematic sketches included in this paper show the basic alterations that occur in the lung

Blood Vessel Hamartias in the Chicken

Cannibalism in the chicken is frequently initiated by the presence of bleeding blood vessel hamartias in the skin. These defects in the growth of blood vessels are very common in the chicken. It is a heritable disease of the White Leghorn chicken. Since all of the major families of White Leghorns have originated from the same basic stock, all have this heritable defect. At times the anomaly becomes a problem in certain families of birds

Nutrition of Diseased Swine

Very little information is available on the feeding of the sick pig. If the subject is discussed, the ration presented is designed for maximum production in a healthy herd of swine. This does not answer the veterinarians problem because his is the reverse. He has the sick pigs. How shall he feed them to make them productive

Ruptured Hepatic Abscesses in Cattle

One of the important complications of hepatic abscesses in cattle is their extension into the posterior vena cava and the hepatic veins. When this occurs the abscesses discharge their contents into the blood stream and produce a thrombus at the site of endothelial injury

Common Skin Lesions in Baby Pigs

Greasy pig disease and parakeratosis focused considerable attention on the skin of the pig and pointed out how critical cutaneous disease can be. The importance of other skin lesions in baby pigs is often overlooked and considerable mortality may occur before their significance is recognized

Spherophorus Necrophorus: Infection in Mink

Sporadic outbreaks, of Spherophorus necrophorus infection in mink are quite commonly observed. One animal, several animals, or a large portion of a herd may be affected. A typical outbreak of this disease is that observed by Dr. J. A. Hunt, Winthrop, Iowa, in a group of mink from which specimens were submitted to the Iowa Veterinary Diagnostic Laboratory

Chronic Copper Poisoning and Pancreatitis in Sheep

During the fall of 1958 a prominent sheep breeder in central Iowa began to lose some sheep. On October 12, 1958, a ram showed anorexia, and appeared as if he were in pain. Upon palpation, tenderness was noted on the right side of the abdomen, and central nervous system disturbances appeared prior to his death. When he became recumbent, he showed running movements and foamed at the mouth. A necropsy examination was not made

Histopathological retrospective study of canine renal disease in Korea, 2003~2008

Renal disease includes conditions affecting the glomeruli, tubules, interstitium, pelvis, and vasculature. Diseases of the kidney include glomerular diseases, diseases of the tubules and interstitium, diseases of renal pelvis, and developmental abnormalities. Renal tissue samples (n = 70) submitted to the Department of Veterinary Pathology of Konkuk University from 2003 to 2008 were included in this study. Tissue histopathology was performed using light microscopy with hematoxylin and eosin stains. Masson's trichrome, Congo Red, and Warthin starry silver staining were applied in several individual cases. Glomerular diseases (22.9%), tubulointerstitial diseases (8.6%), neoplastic diseases (8.6%), conditions secondary to urinary obstruction (24.3%), and other diseases (35.7%) were identified. Glomerulonephritis (GN) cases were classified as acute proliferative GN (5.7%), membranous GN (4.3%), membranoproliferative GN (4.3%), focal segmental GN (2.9%), and other GN (4.2%). The proportion of canine GN cases presently identified was not as high as the proportions identified in human studies. Conversely, urinary obstruction and end-stage renal disease cases were relatively higher in dogs than in human populations
