Study on New Food Resource “Masson Pine Pollen” on Provention of Prostatic Hypertrophy

ZHAO Lin CONG Tao BAO Shah-fen CHEN Gui-tang (Trace Elements Research Laboratory,Nutrition Department,Chinese General Hospital of People's Liberation Army,Beijing 100853,China)  
Objective:To study the preventive effect of Masson Pine Pollen on rats with benign prostatic hypertrophy(BPH) and its mechanism.Methods:Twenty-four SD rats were divided into 3 groups.Three groups were fed with normal diet.The group 2 and group 3 were fed with 3 starch tablets(as placebo)and 3 Masson Pine Pollen tablets per day respectively,and the group 2 and group 3 were be pair-fed with group 1.After two weeks,group 2 and group 3 were injected with testosterone propionate (4mg/kg)which was mixed with olive oil.At the same time,group 1 was injected with olive oil(1ml/kg)alone.Two weeks later, the pathologic slices of prostate were observed,and the sex hormones contents,trace elements zinc,copper and antioxidantive enzymes of serum,prostate and liver were determined.Results:It showed that the prostate hyperplasia symptoms of Masson Pine Pollen group are much better than those of placebo group.Testosterone level of group 3 is lower than that of group 2 and no distinct difference from control.The estradiol level in serum of rats in group 3 is the lowest.Conclusion:Intaking Masson Pine Pollen could improve the symptoms of BPH.The preventive mechanism can regulate sex hormones balance.
