Teh 1H spectrum in 175 serum or blood plasma sanmples of normal

trmour and cancer humoa bodieshas been detected by using homo-nucler presaturation adn freeze-dry methods for the first time with AC80NMR spectrometer

The mean line widths of methyl and methylene resonances in 1H spectrum of different three groups have been measured. The difference between the nomral

tumour and cancer is very signiticant.May be the method to used to detect cancer in furture.
