/SRP:/ 立即急救：确保已经进行了充分的中和。如果患者停止呼吸，请开始人工呼吸，最好使用需求阀复苏器、球囊阀面罩设备或口袋面罩，按训练操作。如有必要，执行心肺复苏。立即用缓慢流动的水冲洗受污染的眼睛。不要催吐。如果患者呕吐，让患者身体前倾或将其置于左侧（如果可能，头部向下）以保持呼吸道畅通，防止吸入。保持患者安静，维持正常体温。寻求医疗救助。 /毒物A和B/

/SRP:/ Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR if necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on the left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. /Poisons A and B/

实验动物：急性暴露/已经确定了通过对雌性瑞士小鼠进行腹腔注射和口服给药，测定了海藻毒素gymnodimine的急性毒性。通过注射给药，gymnodimine具有很高的毒性，LD50仅为96微克/千克。动物要么在注射后10分钟内死亡，要么完全恢复，没有可察觉的长期影响。通过灌胃口服给药后，gymnodimine也具有毒性（LD50 755微克/千克），但当与食物一起给药时，毒性要小得多。在自愿摄入含有gymnodimine的食物的小鼠中，没有观察到毒性迹象，含量足以产生大约7500微克/千克的剂量。用毒扁豆碱或新斯的明预处理可以防止注射gymnodimine的毒性，这表明后者通过阻断神经肌肉接头的尼古丁受体发挥其毒性作用。当与食物一起摄入时，gymnodimine的低毒性表明，这种化合物对人类的风险较低，这一结论与食用被gymnodimine污染的贝类没有有害影响的个案证据相一致。

/LABORATORY ANIMALS: Acute Exposure/ The acute toxicity of the phycotoxin gymnodimine to female Swiss mice by intraperitoneal injection and by oral administration has been determined. Gymnodimine was highly toxic by injection, the LD50 being only 96 ug/kg. Animals either died within 10 min of injection or made a full recovery with no perceptible long-term effects. Gymnodimine was also toxic after oral administration by gavage (LD50 755 ug/kg), but was much less toxic when administered with food. No signs of toxicity were seen in mice voluntarily ingesting food containing gymnodimine at a level sufficient to give a dose of approximately 7500 ug/kg. Pre-treatment with physostigmine or neostigmine protected against injected gymnodimine, suggesting that the latter exerts its toxic effects via blockade of nicotinic receptors at the neuromuscular junction. The low toxicity of gymnodimine when ingested with food suggests that this compound is of low risk to humans, a conclusion that is consonant with anecdotal evidence for the absence of harmful effects in individuals consuming shellfish contaminated with gymnodimine.
