Methods:The SD rats were each given a catheterization of jejunostomy and an inoculation of Walker-256 carcinosarcoma cells subcutaneously. Thirty-six rats were randomized into 3 groups: Group A (balance amino acid＋NS), Group B (balance amino acid ＋5-Fu), Group C (complex amino acids of arginine-enriched and leucine-enriched＋5-Fu).

SD大鼠空肠造瘘，皮下接种Walker-256癌肉瘤，36只接种成功之大鼠随机分为A组、B组(平衡氨基酸+ 5-Fu组)、C组(富含亮氨酸及精氨酸的不平衡氨基酸+ 5-Fu组)。

Interestingly we found that high concentration of L-phenylalanine (Phe, 10mM) and DL-β-phenyllactic acid (PL, 10mM) decreased 〓, while phenylacetic acid (PAA, 10mM) could decreased 〓, then increased, finally decreased 〓. With the normal extracellular balance solution replaced by calcium-free and natrium-free balance solution, PL did not change its effect on intracellular free calcium.

我们用钙成像技术检测氨基酸及其衍生物对未成熟神经元胞浆游离钙浓度的影响，结果发现高浓度苯丙氨酸降低胞浆游离钙，苯乙酸使胞浆内钙浓度降低后升高最后又降低，苯乳酸使胞浆内钙降低更明显。

Were analyzed under different nutritional levels. The results showed that in tuber development, under-or over-supply of nutrients reduced Zeatin content at initial stage and indole actic acid, abscisic acid and jasmonic acid content at middle stage, but increased gibberellins content in the whole process, which caused GA/ABA and GA/JA to be off balance in the key stage of tuberization.

Thirdly, the acrylic rosin was synthesized by the addition reaction from gum rosin andacrylic acid. The levo-pimaric acid was converted into acrylic pimarie acid throughDiels-Alder addition with acrylic acid. The abietic-type acids in the gum rosin were inisomerization balance under high temperature, and the abietic acid and palstric acid would beconverted into levo-pimaric acid and reacted in the later type.

第三，通过脂松香与丙烯酸加成合成了丙烯酸松香，该反应是左旋海松酸与丙烯酸发生Diels-Alder加成反应生成丙烯海松酸，由于脂松香中的枞酸型树脂酸在高温下处于异构化平衡状态，因此随着反应的进行枞酸、长叶松酸等会异构化为左旋海松酸参与反应。
