Results: Proliferation of K562 cells was significantly inhibited by naringenin and the IC50 at 24, 48 and 72h were 455, 225 and 175μmol/L respectively. Cell growth inhibition and apoptosis were observed under light microscope and transmission electron microscope. Observation by flow cytometry indicated that K562 cells were blocked in G0/G1 phase of cell cycle in naringenin group, and S phase cells were remarkably decreased. PCNA expression in each treatment group was remarkably less than in control group.

Application of EBR induced parthenocarpic growth accompanied with active cell division in Jinchun No.4, a cultivar without parthenocarpic capacity, whereas Brz treatment inhibited fruit set and subsequently fruit growth in Jinchun No.2, a cultivar with natural parthenocarpic capacity, and this inhibitory effect could be rescued by application of EBR.

在非单性结实的津春4号黄瓜栽培品种的子房上添加EBR可以诱导单性结实并且提高细胞分裂能力，而在单性结实的津春2号黄瓜栽培品种的子房上喷施BRs合成抑制剂抑制果实生长，最终导致败育，而这种抑制现象可以通过添加EBR得以恢复。

Methods Spectrophotometry was used to study the activity of PLAP in the presence and absence of L Leu. PLAP relative activity was calculated according to the absorbance variation.

方法应用分光光度法分别测定有L－Leu和无L－Leu存在下的酶活力，根据其活力变化求出酶的相对活力；用双倒数作图法，确定L－Leu对PLAP的抑制类型并求出其抑制常数；同时也观察了pH对抑制作用的影响。

And 37. 1%, respectively. The results suggest that 18α-GA down-regulated CYP expression at the transcriptive levels.

表明GL在转录水平下调大鼠肝细胞CYP1A1，CYP2E1和3A1表达，以对CYP2E1的抑制作用最强，对CYP3A的抑制作用最弱，对CYP1A1的抑制作用居中，与整体动物的酶学实验结果基本一致。

But both 20 years and 2 years old of pu-erh tea extracts show a strong inhibitory effects against 2-AAF. In addition, tannic acid, gallic acid, rutin, umbelliferone, and quercetin exhibited stronger antimutagenicities against PhIP than apigenin; while all of these polyphenols displayed inhibitory effect against 2-AAF.

而比较数种多酚类化合物发现，tannic acid、gallic acid、rutin、umbelliferone和quercetin对於抑制PhIP的抗突变作用比apigenin来的有效，但是apigenin和其他多酚类化合物对於抑制2-AAF的抗突变作用则均具有明显的抑制效果。

Previous studies show that p33ING1b is involved in growth inhibition, apoptosis, chromatin remodeling, DNA repair, tumor suppression and cellular senescence, but its biochemical function and involvement in cellular senescence is still not fully uncharacterized.

p33ING1b是一个较晚发现的肿瘤抑制基因 ING1的主要表达形式，自从被成功克隆以后得到了广泛的研究，已有的研究表明，p33ING1b参与了细胞的生长抑制、凋亡、染色质重塑、DNA损伤修复、肿瘤抑制和细胞衰老等。

The results showed that the different molecular weight of the complexes of Chitosan with copperor zinc, the complexes of carboxymethyl Chitosan with copper and the low-molecular-weight iii complexes of sulfation chitosan with copper had excellent inhibition on Valsa mali.

The mycelial growth of Rhizoctonia solani was promoted by vanillic acid and syringic acid at levels of 0.1~1 mM/L, and it was inhibited remarkably by p-counaric acid of over 1mM/L and modestly by ferulic acid. The radial extent of mycelia of Fusarium solani was increased significantly by ferulic acid of 0.1~1 mM/L and limitedly by p-coumaric acid. vanillic acid had paradoxcial effects on the growth, positively at low levels and negtively at high levels, on which Syringic acid had a slight effect.

试验结果显示：浓度为0.1~1mM/L的丁香酸对西洋参立枯丝核菌菌丝生长具有促进作用，香草酸也有一定的促进作用，但不呈浓度效应，浓度在1mM/L以上的香豆酸对其有显著的抑制作用，阿魏酸也有一定抑制作用；对于西洋参根腐菌，阿魏酸对其生长有明显促进作用，香豆酸也有一定促进作用，香草酸表现为低浓度促进，高浓度抑制作用，0.1~1mM/L丁香酸对其生长基本无影响。
