Recently the adenosinetriphosphates have massive highlight due to their high energy source for maintaining all the cell mechanism in the individual. When the A.T.P. release the terminal phosphate, it produces about 8000 calories instead of the 3000 calories from common chemical bonds. The high energy-P bond enables the cell to accumulate a great amount of energy in a very small space and keep it ready to be used as soon as it is needed. The presence of A.T.P. explains why some important cellular functions such as nerve conduction can go on for some time even with complete inhibition of respiration. In recent years the A.T.P. were used in many clinical fields with good effects. In this report A.T.P. 20 mg+Vit B₁ 50 mg+20% Dextrose 20 cc was injected intravenousely for E.N.T. neurologic patient, such as neurogenic hearing impairment, tinnitus, dizziness, soft palte paralysis. By the injection, 40% of neurogenic hearing impairment patients were improved and 62% of tinnitus patients were improved and all the soft palate paralysis patient were completely recovered.
