丙氨酸

In the first part, chemical synthesis, including by acraldehyde, malonic ester, ami no lactone and others were discussed and synthesis by hydantoin was emphasized.

第一部分讨论了DL-蛋氨酸及其衍生物的化学合成，包括丙烯醛法、丙二酸酯法，氨基内酯法等，并着重介绍了海因法。

hydantoin was synthesized from diethyl malonate comprising condensation with 1, 2-dichloroethane, ammonolysis to diamide, Hoffmann degradation to give 5-cyclopropanespirohydantoin, and ring-opening with 40% hydrobromic acid.

以丙二酸二乙酯为原料，先与1， 2-二氯乙烷缩合生成1， 1-环丙烷二羧酸二乙酯，再经氨解生成1， 1-环丙烷二甲酰胺，然后在次氯酸钙溶液中进行Hoffmann降解成环生成5-环丙螺海因，最后在40%氢溴酸中开环得到5-溴乙基海因。

The results showed that there existed significant difference in chlorophyll a, MDA and proline content among different treatments. No significant physiological variation was found in electrolyte exosmosis percentage, POD activity and proline content between the salt treatment and the control during the treatment while the parameters in drought and salt/drought treatment fluctuated remarkably.

结果表明：欧李的叶绿素a、丙二醛和脯氨酸含量在不同的逆境处理间差异显著；碳酸盐处理的电解质外渗率、POD活性、脯氨酸含量等生理指标变化平缓，与对照差异不明显；干旱处理和盐与干旱协同处理的各项指标波动很大。

All the parameters meet the requirement for clinical diagnosis.12 samples demonstrated positive including 6 cases of methylmalonic acidemia,1 case of propionic acidemia,3 cases of tyrosinemia Ⅰ,1 case of maple syrup urine disease and 1 cases of ketosis.

用该方法检测的临床患儿尿样中，发现诊断阳性病例12例，包括6例甲基丙二酸血症、1例丙酸血症、3例酪氨酸血症Ⅰ型、1例枫糖尿病和1例Ketosis病。

There was a little difference betweenphotosynthesis characteristic of the two varieties,response of Jiamusi to low temperature andpoor light was more sensitive than that of Longjiao No.2 and decreased pronouncedly withdecreasing light.6.EC and MDA of pepper leaves increased under low temperature and poor light,therewere no significant differences between them with decreasing light at 21-23℃/8-10℃,butthey were increased dramatically at 15-20℃/5-6℃.So we can speculate that lowertemperature was the direct reason resulted in cell membrane lipid peroxidation.7.No significant difference of SOD activity was observed under suboptimal temperatureand poor light21-23℃/8-10℃;150μmol·m~(-2·s~(-1),but SOD and POD activity substantiallydeclined with lowering temperature and light as well as treatment time.8.Under suboptimal temperature and lower light,proline accumulated to increaseosmotic regulation capacity and alleviate chilling damage.Soluble carbohydrate of pepper leaves decreased progressively and significantly with decreasing temperature and lightintensity as well as longer treatment time.So we think that synthesis and transport ofphotosynthetic product were inhibited by low temperature and poor light as solublecarbohydrate was important component of photosynthetic product.

两个供试辣椒品种之间的光合特性略有差异，佳木斯对低温弱光的反应比陇椒2号敏感，尤其随光照降低，其光合作用显著降低。6、低温弱光胁迫下，辣椒叶片的相对电导率和丙二醛含量都有不同程度的提高，在偏低温下，随着光照减弱，相对电导率和丙二醛含量差异不显著；在极端低温下，随着光照进一步减弱，相对电导率和丙二醛含量明显提高，随着处理时间延长，同一温度下，随着光照降低，叶片丙二醛含量也显著增加，由此可初步判断，低温是导致细胞膜脂过氧化的直接原因。7、经偏低温较弱光21～23℃／8～10℃、150μmol·m~(-2·s~(-1)处理后，辣椒叶片的超氧化物歧化酶活性变化与对照无显著差异，但随着温度、光强的逐步降低和处理时间的延长，SOD、POD活性显著降低。8、在偏低温较弱光下，辣椒能积累更多的脯氨酸，增强渗透调节，减轻低温冷害。

The activity of superoxide dismutase in the myocardial cells was determined by the diphenol method, plasma malondialdehyde content was measured by TBA assay, the culture medium LDH content was measured by the acetonic acid method, the intracellular calcium concentration was measured by fluorescence spectropho- tometer- The results was shown that aspartate-K.

结果显示，门冬氨酸钾镁能减少阿霉素中毒心肌细胞乳酸脱氢酶的释放量，降低细胞内丙二醛含量及游离钙浓度，同时可升高细胞内超氧化物歧化酶活力；结果表明，门冬氨酸钾镁可能通过抗脂质过氧化及逆转细胞内钙离子过负荷作用进而保护中毒心肌细胞。
