Symptoms. Administered in over-doses or for too long a time, carbolic acid produces stomatitis, œsophagitis and vomiting.
True poisoning is characterised by changes in the kidneys and bladder; the urine becomes brown and turbid, and possesses a well-marked carbolic odour, the animals suffer from severe trembling and appear stupid, and coma and paralysis precede death.
The specific lesions consist in parenchymatous nephritis, sometimes accompanied by renal hæmorrhage, cystitis and hyperæmia of the lung and brain. The flesh has an odour of carbolic acid, which renders it unfit for human consumption.
Treatment consists in giving stimulants and slight diuretics, such as ether, alcohol, wine, coffee, saline sulphates, or Glauber’s salt. The last named forms phenyl-sulphuric acid, which is not toxic. Olive, rape, or linseed oil has been recommended. All these drugs are useless if the kidney lesions have become too pronounced.
POISONING BY ALOES.
This form of poisoning is caused by administering over-doses of aloes.
Apart from the accidents possible in pregnant female animals, large doses of aloes produce symptoms of super-purgation—profuse diarrhœa, running down pulse, and nervous prostration.
The lesions are those of gastro-enteritis, the intestine being empty, and its mucous membrane of red colour.
Treatment is confined to administering drugs like camphor, rice, bismuth, opium, chloral, and emollients, which diminish peristalsis and lessen secretion.
