The article presents a study regarding the level of lecithin in the blood of a male spotted deer in different rearing periods. It mentions that high performance liquid chromatography (HPLC) was performed to determine the level of lecithin in the blood. It states that lecithin levels regulates the anti-aging process which is reduced in the service period.

Pilose antler polysaccharides (PAPS) were obtained from pilose antler by the method of extraction, seperation and purification. The sample of PAPS was purified with the column chromatography on DEAE-Cellulose 32 and Sephadex G-75. Its molecular weight is about 70 -80 kDa detected by SDS-polyacrylamide gel electrophoresis, the content of total sugar is 825.51 µg/mg determined by phenol-sulfuric acid method, the content of protein is 20.27 µg/mg determined by Foiln-hydroxybenzene method, and the content of sulfate radical is 58 µg/mg determined by barium sulfate turbidity. The sample of PAPS exhibits typical absorption of polysaccharide characterized by IR analysis. [ABSTRACT FROM AUTHOR]
