Clinical and Pathological Studies of Jimson Weed (datura Stramonium) Poisoning in Horses
نویسنده
چکیده
A spontaneous intoxication in 34 horses after intake of freshly harvested ensiled maize, accidentally contaminated with young Datura stramonium plants was followed. In a 7-day study, the full clinical status was monitored and this included among others the following: body (rectal) temperature, respiratory and heart rates, colour and humidity of visible mucosae, changes in pupil size, appetite, thirst, general behaviour, locomotion, sensory perceptions, urination, defecation. Results manifesting in these clinical parameters were a generalised intoxication associated with mild hyperthermia, tachycardia, polypnoea, dyspnoea and shallow breathing, mydriasis, dry oral, rectal, vaginal and nasal mucosae, acute gastric dilatation and severe intestinal gas accumulation, anorexia to complete refusal of feed, decreased or absent thirst, absence of defecation and urination. On treatment, the clinical indices were normalized between days 2 and 5. In dead horses (n=2), necropsies and pathological studies were performed. They revealed a toxic liver dystrophy, cardiac lesions and substantial dystrophic and necrotic processes in kidneys. The observed clinical signs, the pathomorphological changes and the applied therapy could be used in the diagnosis, differential diagnosis, prognosis and treatment of Jimson weed intoxication.

hallucinations is unusual for intoxication with atropine or scopolamine, but could be explained by delayed digestion of non-ground Jimson weed seeds. Postprandial ‘inability to vomit’, followed by unconsciousness and auditory hallucinations, as reported by this patient, clearly is consistent with tropane alkaloid poisoning, and, together with laboratory results (50 seeds D. stramonium/kg of gra...
