As an anaphrodisiac may be given camphor, or camphor bromide, ergot or potassium bromide, along with the mild stimulating antiseptic eucalyptol or copaiba. But the irrigation of the urethra, bladder and as far as possible the prostate with such antiseptic solutions as potassium permanganate (1:10000) or silver nitrate (0.5 to 1:100) or zinc chloride (1:100) is desirable. These should be injected into the urethra so as to reach the bladder, the contents of which they will render antiseptic and thus protect the organ against the transported microbes of the prostate. In man iodoform, europhen, and ichthyol are made into a bougie with gum, palm butter or other soluble liquifiable agent and inserted in the urethra as far as the prostatic part. Similar agents are used as suppositories or enemata. Hertwig’s iodine ointment on the perineum may be advantageously replaced by sinapisms. HYPERTROPHY OF THE PROSTATE. In old dogs. Causes: age, overfeeding on albuminoids, rectal impaction or irritation, calculus, cystitis, urethritis, productive inflammation, trophic derangement when function declines. Lesions: hypertrophy general or partial, hard or soft, condensed or with sacs of pus, red or pale. Infective cystitis. Calculi. Symptoms: straining before urine comes, small or weak stream, sudden check, last part purulent or mucous, incontinence, triple phosphate, ammoniacal odor, crystals and dark color imply calculus. Diagnosis: by rectal exploration, and catheterization. Treatment: palliative, moderate, farinaceous, laxative diet, warmth, correct contiguous troubles, iodine, castration, extirpation of prostate. This has been seen almost exclusively in old dogs, among the domestic animals.
