为了解偏头痛患者心理学改变与某些生化指标的关系，32例患者于发作间歇期进行四种心理量表和P300检查的同时，检测了血清Ca2+、Mg2+和血管紧张素Ⅱ（AⅡ），以32例健康人作对照。结果：偏头痛组的生化指标无显著异常；除P300中的N2的峰一峰波幅（P-PAm）与Ca2+／Mg2+／比值显著负相关（P＜0．01）外，其余各参数和心理量表与上述生化指标间无相关性。经治疗症状好转者血清Mg2+显著升高（P＜0．05）。全文对所得阳性和阴性结果的原因进行了探讨，并认为提高血清Wg2+的水平，有利于防治偏头痛的发作。
To understand the relationship between psychological changes and some biochemical parameters in patients with migraine, 32 patients were tested for serum Ca2 +, Mg2 + and angiotensin Ⅱ (AⅡ) simultaneously with four psychometric scales and P300 during the interictal episode. Take 32 healthy people as control. Results: There were no significant abnormalities in biochemical parameters in migraine group. Except for the significant negative correlation between peak-peak amplitude (P-PAm) of N2 in P300 and Ca2 + / Mg2 + / ratio (P <0.01) No correlation between the table and the above biochemical indicators. The serum Mg2 + of the treated patients improved significantly (P <0.05). The full text of the positive and negative results of the reasons were discussed and that raising the level of serum Wg2 + is conducive to the prevention and treatment of migraine attacks.
