Nephritis, Inflammation of the Kidneys The kidneys are not unfrequently the subject of inflammation in the horse. It may be induced by powerful or repeated diuretics, such as saltpetre, which is a most dangerous medicine, or from hard and long riding by a heavy rider, or heavy weights; or by leaping or being suddenly pulled up on his haunches, the inflammation being propagated from the lumbar muscles to the kidneys, or by exposure to cold and wet, by rain dripping upon his loins during exercise, and especially if these organs have been previously weakened. SYMPTOMS.—The early symptoms are those of fever, the pulse full, hard and quickened, afterward becomes small and weak; the horse looks around anxiously at his flanks; stands with his hind legs wide apart; is unwilling to lie down; straddles as he walks; expresses pain in turning; the back is somewhat arched; he shrinks when the loins are pressed upon, and there is some degree of heat felt there. The urine is voided in small quantities; frequently is high-colored, and sometimes bloody; and there is frequent and often violent effort and straining, but the discharge is very small, sometimes suppressed. TREATMENT.—Give fifteen drops of H.H., and repeat every two hours. Should there be very high fever, great heat, etc., the A.A., may be alternated with it, giving fifteen drops every intermediate hour in urgent cases, but in general the H.H., will be quite sufficient, and should be continued at prolonged intervals to entire recovery. But a few doses will be required to show us the great value and efficacy of the remedy. Cistitis, Inflammation of the Bladder This disease is usually the result of giving diuretics, such as saltpetre, cantharides, or similar irritating medicines. It may also be the effect of a cold and exposure, or of a stone in the bladder, and the disease may occupy the neck of the bladder, or the organ itself. The symptoms are similar to that of Inflammation of the Kidneys; the horse makes frequent and painful attempts to stale, but passes only a few drops of water at a time. The bladder cannot retain the urine from its excessive irritability, so that the attempt to void it is constantly going on. The urine may be clear, or mixed with mucus, or stained with blood. THE TREATMENT is the same as for Inflammation of the Kidneys, the remedy for that disease, H.H., being given every two hours, in doses of fifteen drops, or less frequently, according to the urgency of the case. In some cases the A.A., may be given in alternation, as for Inflammation of the Kidneys; but in general, the remedy first mentioned H.H., will be found every way efficient and available.
