晕厥
晕厥指的是大脑一时性缺血而导致短时间内丧失自主行动意识的表现。
晕厥与昏迷（或休克）不同，昏迷（或休克）的时间一般较长，晕厥较短。晕厥应立刻救治，否则可能会发生致残或其它危险甚至致死。晕厥的发病率较高，甚至在正常人中也有一定的发病率，病因一般是强烈地短时间内的精神刺激，如亲人死亡等。其发作为间歇性，潜在原因较多，涉及科目很多，并且没有权威而统一的治疗标准，所以常常难以诊治。
Daylamites
Map showing Daylam in western Tabaristan. The Daylamites or Dailamites (Middle Persian: Daylamīgān ; Persian: دیلمیان Deylamiyān ) were an Iranian people inhabiting the Daylam—the mountainous regions of northern Iran on the southern shore of the Caspian Sea. [1] They were employed as soldiers from the time of the Sasanian Empire, and long resisted the Muslim conquest of Persia and subsequent Islamization. In the 930s, the Daylamite Buyid dynasty emerged and managed to gain control over much of modern-day Iran, which it held until the coming of the Seljuq Turks in the mid-11th century.
