562 Diseases of the Pancreas. 



tissue, subsequent shrinkage of wliicli led to atrophy of the 

 gland parenchyma. Catarrh of the bile ducts and chronic in- 

 terstitial hepatitis were present at the same time. During life 

 the symptoms shown by the horse were : jaundice, partial loss 

 of appetite, languor, unsteady gait and emaciation. The feces 

 were dry and pale in color. In two months the animal was in 

 a state of complete collapse. 



Chronic Inflammation of the Pancreas. This was observed 

 by Siedamgrotzky in a horse, the animal showing loss of 

 hair, edema, leucocythemia and debility. The stroma of the 

 pancreas was greatly increased in amount, and the gland tissue 

 reduced, and the ducts were obstructed with viscid mucus and 

 calcified flakes. (Kitt found a similar lesion in a horse.) In 

 a case recorded by Wheatley, there was extensive cirrhosis of 

 the gland which weighed sixteen pounds, the ducts were dilated 

 and filled with material resembling albumen. The horse had 

 shown gradual wasting, edema and excoriation of the skin at 

 places. 



Suppuration of the pancreas may be set up by the presence 

 of foreign bodies in Wirsung's canal. In a case recorded by 

 Goubaux in the horse, the foreign body was a straw stalk, and 

 in the dog, Bruclmiiiller records the presence of a needle in 

 the canal. The s^^llptoms presented were loss of appetite, ema- 

 ciation, occasional attacks of colic and susceptibility to pres- 

 sure in the hypogastric region. Schattler found hemorrhages 

 and a number of small abscesses in the pancreas of a horse, 

 caused by the penetration of a piece of wire from the duodenum. 

 The s^imiptoms shown were: loss of energy, frequent groaning, 

 and variable appetite. 



Nodular fat-necrosis of the pancreas occurs in absolutely 

 normal lobules in fattened pigs (Marek, Eonai). It also 

 occurs exceptionally in the dog and horse. No s^anptoms are 

 produced and in cases where they cause sudden death they may 

 be associated with multiple hemorrhages of the gland. Hemor- 

 rhages in the pancreas and surrounding tissues were found in 

 two cases by Prettner and in one case l)y Mettam, in dogs which 

 had shown s^i^nptoms of vomiting, alxlominal pain and sudden 

 collapse. Prettner is inclined to think that the condition was due 

 to an infection from the intestine. In Mettam 's case the gland 

 w^as enlarged to a considerable extent and beset with necrotic 

 foci. In one case similar lesions were found in a horse that 

 had died from acute enteritis of the small intestine and peri- 

 tonitis. 



Atrophy of the pancreas was found by Lienaux, Eber and 

 Sendrail in dogs dead of diabetes mellitus. In Lienaux 's case 

 the pancreas was reduced to 3 cm. in length and 1 cm. in width,
