INDEX OF DISEASES AND REMEDIES 783 



PAROTIDITIS. 



Inflammation of parotid gland. Traumatic. May be due to strangles, 



pharyngitis, salivaiy calculus, and in the ox to actinomycosis. 

 Hot moist compresses or poultices. 



Infriction as required of mildly stimulating or anodyne ointments. 

 When chronic or indolent, iodine or cantharides dressings. 



PARTURIENT PARALYSIS. MAMMARY TOXAEMIA. 



Milk fever : A disease of cows (and ewes) occurring at parturition, or 

 a few days thereafter ; characterised by loss of consciousness, and 

 paralysis of niotion and sensation ; sometimes ushered in by cerebral 

 excitement, spasms, and convulsions ; attacking animals in the prime 

 of life, in good condition, and free milkers. Formerly mortality 

 ranged from 40 to 60 per cent. No marked pathological changes. 

 Those recovering do so quickly, and usually perfectly. Cause 

 of disease still unexplained, but probably due to a nerve toxin 

 formed in the udder. 



Ever's treatment: Subcutaneous injection of 50 grains of caffeine dis- 

 solved in six drachms of boiled water; then, after emptying the 

 udder, insufflate each quarter with pure oxygen or filtered air; 

 prevent escape of air by rubber ring on each teat ; remove rings in 

 one or two hours later ; knead the udder after insufflation. 

 If swallowing difficult, give cathartic and other medicine with Read's 



pump. 

 Prop on sternum : keep up head : turn patient from one side to other 



every three hours. 



Schmidt's treatment: Dissolve Sij. to 3iij. pot. iodide in 35 ounces of 

 boiling water ; cool to blood heat, empty udder and inject one-fourth 

 of the solution into each teat ; knead the udder after injection. 

 If urine retained, empty bladder by catheter twice daily, 

 Linseed gruel occasionally by stomach pump and clyster. 

 Rubefacients to spine ; cold pack sometimes beneficial. 

 Until recovery fairly established, withhold dry food, but allow mashes 



and diluents. 

 Purgatives, counter-irritants to the spine, pot. iodide and nux-vomica 



relieve resulting weakness. 

 Prevent by sparingly feeding susceptible subjects for a month before 



calving. 



Cathartic a fortnight before parturition, and another if required imme- 

 diately after. 



Milk cow a fortnight before calving, earlier if milk can be drawn, and 

 empty bag twice daily. 



PATELLA, PARTIAL LUXATION OF. ARREST OF PATELLA ON FEMORAL TROCHLEA. 



Occurs in colts, occasionally in cattle, and in horses of any age. 

 After reduction keep limb extended and slightly forward for several 



hours by cord attached to the fetlock and carried round the neck. 

 Put on a shoe high at the toe and projecting forward. 

 Blister stifle. 



PERICARDITIS. 



Inflammation of serous covering of heart. Rare in horses and dogs, 

 in which usually rheumatic or infective ; more frequent in cattle and 

 goats, from their swallowing sharp-pointed bodies, which pass 

 through the walls of stomach and diaphragm, and enter the peri- 

 cardium, producing pericarditis. Frequently fatal. 

 Morphine hypodermically usually relieves acute pain. 

 Woollen cloths wrung out of hot water applied to the chest for an hour 



or two at a time. 



Digitalis, strophanthus, caffeine, moderate rapid, violent, irregular heart 

 action.
