毒碱样症状主要表现为平滑肌痉挛及腺体分泌亢进.虹膜括约肌收缩致瞳孔缩小;胃肠平滑肌兴奋,引起恶心、呕吐、腹痛、腹泻,甚至大便失禁;膀胱逼尿肌收缩,发生尿失禁;支气管平滑肌收缩,支气管腺体分泌增加,导致呼吸困难及紫绀,严重时可发生肺水肿;汗腺及唾液腺过度分泌,引起大汗及流涎. 烟碱样症状运动神经兴奋,早期表现为肌束颤动,常先自小肌群如眼睑、面部、舌肌开始,逐渐发展至全身,胸部发紧,动作不协调,甚至出现全身肌肉抽搐.严重者可转入抑制状态,表现为肌无力、瘫痪,最后可因呼吸肌麻痹而窒息死亡.交感与副交感神经节兴奋产生的综合作用较为复杂,可引起心率减慢或加速,血压升高.严重者由于血管运动中枢麻痹及心肌纤维断裂,反致血压下降,甚至出现休克.危重中毒以及临终前,体温常低于正常.中枢神经系统症状早期可有头晕、头痛、倦怠无力、失眠、多梦;晚期可出现嗜睡、意识模糊,甚至 Symptoms of alkaloid mainly manifested as smooth muscle spasm and gland secretion hyperthyroidism.Iris sphincter contraction caused by pupil contraction; gastrointestinal smooth muscle excitement, causing nausea, vomiting, abdominal pain, diarrhea and even fecal incontinence; bladder detrusor contraction, urinary incontinence occurs; Bronchial smooth muscle contraction, bronchial gland secretion increased, resulting in breathing difficulties and cyanosis, severe pulmonary edema can occur; sweat glands and salivary glands over-secretion, causing sweating and salivation. Nicotinic-like motor nerve excitability, early manifestations of fascicular fibrillation, Often small muscle groups such as the eyelids, facial, tongue muscle began to gradually develop to the whole body, chest tight, uncoordinated movements, and even muscle twitch. Severe cases can be transferred into the state of inhibition, manifested as weakness, paralysis, and finally May be due to respiratory muscle paralysis and suffocation death Sympathetic and parasympathetic ganglia stimulation of the combined effect is more complex, can cause slow or accelerate the heart rate, blood pressure, severe vascular paralysis due to central paralysis and myocardial fibrillation, anti-induced blood pressure drop , And even shock .Acute poisoning and before dying, body temperature is often lower than normal.Central nervous system symptoms may have early dizziness, headache, Lazy weakness, insomnia, dreams; drowsiness may occur late, confusion, and even
