DIGESTIVE SYSTEM 111 



Lesions. — The but-oal, pharyngeal, gastric, and intestinal mucosa 

 show inflammation. The liver and kidneys are enlarged, due to fatty 

 degeneration of their parenchyma, and the heart also is usually af- 

 fected by fatty changes. The content of stomach and bowel are 

 phosphorescent when examined in the dark, and a distinct phos- 

 phorous odor emanates from the stomach and bowel when these 

 organs are opened. 



Symptoms. — Intense thirst, difficult deglutition, vomition, and 

 colicky pains, associated with weakness and incoordination, are 

 produced by phosphorous poisoning. 



Treatment. — Emetics and the administration of turpentine in 

 mucilaginous substances, when applied energetically, will sometimes 

 save the patient. 



Pheno! {Carbolic Acid) 



Phenol and various compounds containing phenol or crude car- 

 bolic acid are extensively employed on many stock farms as the 

 essential ingredient in dips and they are also used for disinfection. 

 Quantities of such agents may be obtained by swine in wallow holes, 

 in contaminated troughs and in feeds. If such waste products con- 

 lain sr.fficient phenol and they are consumed by swine, poisoniny 

 may follow. 



Lesions. — The mucous membranes of the digestive tube but espe- 

 cially of the mouth and stomach will be destroyed and the mucosa 

 may still be intact and appear as a gray or white membrane. The 

 submucosa beneath the areas of destroyed mucosa will be congested 

 and hemorrhagic. If sufficient has been consumed to destroy life 

 there will be nephritis, bloody urine, and congestion of the liver. 



Symptoms. — Salivation, vomition, colicky pains, muscular weak- 

 ness, and the urine will be dark in color and have a ppt^uliar odor. 



Treatment. — The administration of a rapidly acting emetic such 

 as one-half-grain doses of apomorphin. The mouth should be swabbed 

 ■ with alcohol. Purgatives are indicated, particularly the salines, 

 such as epsom salts, using large doses. 



Bichlorid of Mercury (Corrosive Suhlimiitr) 



Bichlorid of mercury is frequently used in the disinfection of 

 farm buildings and equipment and sufficient quantities may be ob- 

 tained by swine to produce poisoning. Commercial calomel may 

 contain varying quantities of corrosive sublimate and the use of
