CYSTICERCUS AND T RICH IX A 355 



tinctvire of colchiciim, or antipyrin. The first three drugs produce the 

 most favorable results. 



In the chronic form of the disease, various cutaneous stimulants 

 have been used, such as spirit of camphor, opodeldoc, spirit of mustard, 

 but we must remember that their influence is more due to the massage 

 than to anything else. It is advisable to rub the stimulating embroca- 

 tion into the skin, either by the hand or with a woolen rag. Albrecht 

 has found that this therapeutic treatment may be greatly improved by 

 putting the patient into a bath of 28°, rubbing it dry and wrapping it in 

 hot blankets. 



Cysticercus and Trichina. 



Cysticercus. — Reference has already been made to the presence of 

 cysticercus in the brain and they also appear in numerous other organs, 

 particularly the muscles, and there is special interest in the fact that 

 their presence in large numbers in the muscles may cause symptoms 

 very similar to those of muscular rheumatism. One dog which was 

 very stiff during life and kept the head bent to one side after death, in a 

 section of the psoas muscle about an inch square there were found eight 

 or ten cysticerci the size of a pea. Trasbot found in a dog that during 

 life showed violent pain on touching the skin, pressing the muscles and 

 on making certain movements of the body, after death numerous cysti- 

 cerci of the Taenia solium in the entire muscular system. (For further 

 details concerning cysticercus, see Internal Parasites). 



Trichina. — Trichina is extremely rare in the dog. It is observed more 

 in some countries than in others. Of 858 dogs examined in one clinic, 11 

 or i per cent, were found infected with trichina. In 2910 post-mortems 

 one-half of 1 per cent, were found effected with trichina. The symp- 

 toms which appear after a dog has eaten meat containing trichina 

 in large numbers are for two weeks a bloody diarrhoea, loss of appetite, 

 pain, convulsions, and after the animal was destroyed on microscopical 

 examination of the muscles they were found to contain numerous mi- 

 grating trichina. Leistikow fed three dogs with trichinous meat which 

 afterward developed diarrhoea, great exhaustion and then became normal; 

 they were killed six weeks later and the flesh was found to contain 

 incapsulated trichina. Paroncito obtained similar results from feeding 

 dogs with meat containing trichina, and two were killed after a few days 

 and the others died in four weeks. In all cases trichina was found in 

 the muscles.
