:''For an island in Bulgaria, see Persin Island'' |Section2= |Section3= }} Persin is a fungicidal toxin present in the avocado. It is generally harmless to humans, but when consumed by domestic animals in large quantities it is dangerous.〔(ASPCA Poison Control: Avocado )〕 Persin is an oil-soluble compound structurally similar to a fatty acid, and it leaches into the body of the fruit from the pits. Negative effects in humans seem to be primarily in allergic individuals. == Pathology == Consumption of the leaves and bark of the avocado tree, or the skin and pit of the avocado fruit have been shown to have the following effects:〔 *In birds (which are particularly sensitive to the avocado toxin), the symptoms are: increased heart rate, myocardial tissue damage, labored breathing, disordered plumage, unrest, weakness, and apathy. High doses cause acute respiratory syndrome (asphyxia), with death approximately 12 to 24 hours after consumption. *Lactating rabbits and mice: non-infectious mastitis and agalactia after consumption of leaves or bark. *Rabbits: cardial arrhythmia, submandibular edema and death after consumption of leaves. *Cows and goats: mastitis, decreased milk production after consumption of leaves or bark. *Horses: Clinical effects occur mainly in mares, and includes noninfectious mastitis, as well as occasional gastritis and colic. *Cats, Dogs: vomiting, diarrhea. *Hares, pigs, rats, sheep, ostriches, chickens, turkeys and fish: symptoms of intoxication similar those described above. The lethal dose is not known; the effect is different depending upon the animal species. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Persin」の詳細全文を読む スポンサード リンク
