TFP activated NAD kinase in tomato and strawberry fruit, CPZ activated the enzyme in tomato but in strawberry fruit, which indicated that ethylene-started and promoted maturation, ripening and senescence of fruit were related not only to increase in intracellular Ca〓 concentration and CaM content, but also to NAD kinase, and indirectly showed that CaM could regulate NAD kinase in two fruit.

以上结果表明乙烯启动和加速果实成熟衰老不仅与胞内Ca〓浓度和CaM含量增加有关，而且与CaM的另一目标酶——NAD激酶有关，并间接证明CaM对两种果实NAD激酶具有调控作用。

X 6 x 25 mm3 tested plates were cut from samples prepared from heating the PLLA powder at 220 oC under vacuum without pressure and gradually cooled from 220 oC until room temperature in a pot vented with nitrogen for one night. The crystallinity value of resultant samples was 43 %. These tested plates were implanted in the dorsal subcutis of S.D. rat after sterilization with ethylene oxide and removed at 1 d、3 d、7 d、21 d and 35 d intervals. These specimens were examined histologically with paraffin embedding section and resin embedding grounding section by light microscopy to evaluate tissue response. Three points bending test, viscosity and thermal properties were also examined.
