Yen, Y. C., G. W. Wang and A. C. Liu. Distribution of lipid fractions and levels of central nervous system. Chinese J.Physiol.,20(2):145-150,1968.-Chemical studies were made on the central nervous system of four dogs sacrificed 24 hours after fasting under pentobarbital(30 mg/kg,i.p.).When blood-free, left frontal and parietal lobes of cerebral cortex, left cerebellar cortex from the middle line, basal ganglia of midbrain of upper brain stem, pons and medulla of lower brain stem, T(subscript 3-6)of the thoracic cord and L(subscript 2-5)of the lumbar cord were removed for water content study and lipid analysis. With the wet tissue, the water content showed a declining trend and triglyceride exhibited random changes along the neural axis. When the wet tissue unit of each observation was converted into fat-free dry tissue, the trend of change of each lipid fraction was so disturbed that no head or tail could be made out. The reason of this disparity between the ways of treating data was explained partily on the opposite trend of change between water content and the total lipid fraction. The role played by breeding and aging in this matter remained open while other questions were raised.
