因此，NAD激酶、NADP磷酸酶可能通过直接影响NAD和NADP的比例而参与果实呼吸作用和乙烯生成的调节从而影响其后熟衰老过程。

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。

The polymerization systems can be divided into four categories: styrol, acrylate, hydrophilic and non-ethylene according to the difference of the structure and characteristic of the monomer.

总结了目前各种不同组成的分散聚合体系，按单体的结构、性质的差异，分别介绍了苯乙烯类、丙烯酸酯类、亲水性单体类、非乙烯单体类的分散均聚合研究情况，列出了各种分散聚合体系中的介质、稳定剂和引发剂等组成。

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.

使用日本岛津公司重量分子量21万之聚乳酸，以220 ℃热熔法，在氮气中自220 ℃缓慢降温产生结晶度43 %的聚乳酸，并切割成2 x 6 x 25 mm3试样，经环氧乙烯灭菌后，植入在Sprague Dawley大鼠背部皮下组织，经1天、3天、7天、21天、35天五个试验期间，以石腊及树脂标本之组织学观察，评估其组织反应并以三点弯曲强度、黏度及热性质检测，评估其物理性质变化。
