A method is provided for treating a neuromuscular defect in a subject. The apparatus as well as the method according to the present invention enable to generate a molecular beam for a variety of molecules, particularly for the neutral molecules which can be decomposed by heating at a high temperature or those which can not be sublimated or vaporized even by heating at a high temperature, as long as the sample solutions are prepared.
