Parenchymatous Hepatitis. 501 



decreased, glairy, brownish red, groaning in defecation, excited circulation 

 and breathing, increased icterus by third day, foetid, colorless, diarrhoea. 

 Diagnosis: Coincidence of fever, prostration, icterus, painful defecation, 

 foetid diarrhoea, light color of stools, tenderness and flatness on percussing 

 hepatic area. From influenza by absence of watering eyes and contagion. 

 Prognosis in horse : Very grave unless urine is free. Treatment in horse : 

 Portal depletion, calomel, ipecacuan, salines, diuretics, fomentation of loins, 

 antiseptics, derivatives, mineral acids, bitters. Careful laxative diet in con- 

 valescence. Symptoms in cattle : Slower onset, anorexia, dullness, depres- 

 sion, drivelling saliva, grinding teeth, icterus, constipation, later fcetid 

 diarrhoea, pale colored stools, recumbency, groans on rising, arching back, 

 tender right hypochpndrium, fever. Prognosis grave. Death in five to six 

 days. Treatment as in horse : Only saline laxatives. Symptoms in dog : 

 Muscular tremors, staring coat, hyperthermia, icterus, fcetid breath, ventral 

 decubitus, extreme prostration, anorexia, tender right hypochondrium, di- 

 minished urine. Death in two or three days. Treatment in dog : Calomel 

 and jalap, diuretics, laxatives, derivatives, germicides, in convalescence, 

 mineral acids, bitters, careful diet. 



The different forms of inflammation of the liver are distin- 

 guished according as they affect, especially the hepatic cells and 

 tissue of the acini (parenchymatous), as they result in suppura- 

 tion (suppurative, catarrhal, abscess), as they cause necrobiosis 

 in nodular masses (infectious or necrotic), as they lead to fibroid 

 thickening under the peritoneum and proper capsule (perihepa- 

 titis) ; or as they cause general fibroid induration of the organ 

 by increase of its connective tissue (cirrhosis). 



PARENCHYMATOUS HEPATITIS, ACUTE YELLOW 

 ATROPHY OF THE LIVER. 



" The characteristic morbid lesion in this disease is the degenera- 

 tion of the liver cells, loss of their protoplasm and nuclei and of 

 their normal functions. It may be circumscribed to limited 

 areas, or may affect the liver, generally. As the hepatic functions, 

 are so intimately related to those of the bowels and kidney, the 

 affection is usually accompanied by inflammations of these organs 

 as well.
