44 PRACTICE OF EQUINE MEDICINE. 



What is meant by restorative treatment ? 



This is where the aim is to build tip the system aud supply 

 something wanting in the system, as phosphates in rickets, and iron 

 in ansemia. 



What is radical treatment? 



This is where a rapid impression is made upon the system and 

 the course of a disease is cut short. 



Define palliative treatment. 



It is where suffering is allayed, or, where the disease is incur- 

 able, the symptoms moderated and the suffering relieved. 



2. DISEASE. 

 Define disease. 



Disease may be said to be a deviation of an organ from the 

 normal, either in function or structure, or both. 



How may diseases be divided ? 



Into functional and organic diseases. 



Give the definition of each. 



A functional disease is one in which there is an alteration of 

 the function of an organ, there being no structural change. 



An organic disease is where there is a change in function due 

 to some structural alteration. 



Define a contagious disease. 



It is a disease due to a specific cause, capable of being repro- 

 duced in the body, and of being transmitted from the sick to the 

 well ; for example, glanders, small-pox. 



What is an infectious disease ? 



It is one which is due to a disease germ introduced into the 

 economy from without, but not capable of being reproduced in the 

 body, hence not capable of being communicated from one animal 

 body to another, as influenza, tubercle. This is sometimes called 

 a iniasmatic disease.
