| Abstract;We studied the function of potato in vitro and in vivo. 1) Potatoes contained 80-96 mg/100 gf.w. polyphenol content deffer from each potato. AINOAKA is a most amount of polyphenol than other potatoes. 2) Potatoes (AINOAKA, DEZIMA and NISHIYUTAKA) in Nagasaski had both resolved actibity of nitrite and anti-oxidant actibity. Both actibity of AINOAKA is stronger than DEZIMA and NISHIYUTAKA. 3) Enhanced cell proliferation was observed in normal human diploid cells cultured in the medium containing potato powder (A). The total population doubling numbers (TPDNs) of these cells increased significantly compared with those of the control cells, indicating that the life span of normal human cells is extended. Because there was no significant difference in the telomere length between the control cells and the cells cultured in a potato powder (A) -containing medium, it can be hypothesized that anti-oxidants in the potato powder (A) may ameliorate cellular aging. 4) The effects of dietary potato powder (B) on body weight, liver weight, the concentrations of triacylglycero and cholesterol in plasma and liver and the concetration of protein in urea were studied in SD-rats fed non-cholesterol and cholesterol-enriched diets. Dietary potato polyphenol extract tended to decrease the plasma concentrations of triacylglycerol and total cholesterol in rats. The concentration of protein in urine were tended to be higer in rats fed the potato powder (B) diet compared to the controls. (author abst.) |
