我是兽医师，我转录一下以前po在pet版的文章 Grapes/Raisins Veterinary & Aquatic Services Department, Drs. Foster & Smith, Inc. Toxin Thought to be due to an unknown compound in the "fleshy" part of the grape. There have been no problems associated with grape seed extract. Source Grapes and raisins. General Information Many dogs like raisins and grapes. They should only be given in a very limited amount on an infrequent basis, and should not be left where a dog or cat can have access to them. The unknown toxin damages the kidneys. Toxic Dose One known amount is 1 ounce of fruit per 2.2 pounds of body weight. Signs Vomiting, diarrhea, lack of appetite, lethargy, or abdominal pain. Immediate Action Induce vomiting and seek veterinary attention. Veterinary Care General treatment: The induction of vomiting may be continued, gastric lavage is performed, and activated charcoal administered, if needed. Supportive treatment: The animal will be monitored and treated for kidney disease/failure with fluids, diet change, and medications. Specific treatment: Unavailable. Prognosis Variable Keep this and all other medications out of the reach of children and pets. If you think your pet has been poisoned... Contact your veterinarian or one of the Animal Poison Hotlines (listed below) if you think your pet may have accidentally received or been given an overdose of the medication. Reference: http://www.peteducation.com/article.cfm?cls=2&cat=1939&articleid=2409 按照上述所说的中毒剂量， 台湾单位即是1kg体重摄食超过28.35g，会有中毒症状。 如果犬只重量为25kg，一颗葡萄重28.35g， 吃25颗就会开始产生中毒症状。 不过机制尚未了解，如果你想对於医界有所贡献，你可以尝试看看。 但是如果就健康的立场上，还是建议你能免则免。 ※ 编辑: qzpm 来自: 220.136.50.150 (07/08 20:08)
