32 ENDOCRINE THERAPEUTICS 



who died at 80 years of age, had three or four 

 injections of adrenalin daily for eight years, but 

 her pressure never rose above the normal, and 

 there were no signs of atheroma. 



In ordinary spasmodic asthma, adrenalin in- 

 jections probably give relief more quickly than 

 anything else (with the exception of hypodermic 

 morphia, which one naturally avoids as much as 

 possible). 



If blood-pressure be normal or above, the com- 

 bination of 2 minims of liq. trinitrin with 7 or 8 

 minims of liq. adrenalin often gives better results ; 

 it is better to dilute them by filling the syringe 

 with boiled water. Neat adrenalin sometimes 

 produces pallor and a feeling of faintness, 

 which is more alarming to the friends than to the 

 patient. 



If the blood- pressure be sub-normal the addition 

 of pituitrin (ampoutes of this combination are 

 sold by the chief wholesale houses) instead of the 

 trinitrin is often very useful. In the acute 

 dyspncea of cedema of the lungs or of cardiac 

 dilatation, with or without high pressure, adrena- 

 lin injections act generally like magic. This is 

 due to two causes. Firstly, the coronary arteries 

 of the heart are dilated, giving the heart muscle 

 a larger flush of blood, and consequently greater
