Secondly, through the filariasis immune experiment, people improve that the skin is wiped with the levamisole liniment at regular intervals instead of preparing the bacterin for inoculability, levamisole actions of resisting the virus and infection are exerted without the disease when inoculating the pathogeny, and the specificity immune protection is obtained under the pathogeny action, the immune preventive intention is reached just as injecting the bacterin.

二是，经丝虫病免疫实验证实，不用制苗接种，通过左旋咪唑搽剂定期皮肤涂药，在接种病原时，发挥左旋咪唑抗病毒、抗感染作用而不发病，并在病原作用下，获得特异性免疫保护，就像注射疫苗一样达到免疫预防的目的。

Result: Maidang Rutong granule showed significant enhancement for lactescence and the offspring's body weight. It could antagonize the decrease of serum prolactin and the atrophy of mammary gland induced by l -dopa.

结果：麦当乳通颗粒可显著增加缺乳母大鼠的泌乳量，可显著对抗左旋多巴引起的母鼠血清催乳素减少，明显对抗左旋多巴引起的大鼠乳腺萎缩，并显著提高其所喂养的仔鼠体重增加率。

A left-handed molecule is one that causes polarised light to rotate to the left.

左旋分子就是使偏振光发生左旋的分子。

An isocratic HPLC assay was developed for simultaneous determination of levodopa methyl ester and levodopa in the hydrolysate of levodopa methylester.

采用等度高效液相分析方法同时检测左旋多巴甲酯及其水解产物左旋多巴，得到了一系列水解速率常数以及氢离子浓度和温度对水解反应的影响。

The patients with methylmalonic acidemia and homocystinuria should be mainly treated with vitamin B12, betaine and L-carnitine, while the patients with isolated methymalonic acidemia should be treated with protein restriction, the special milk formula without isoleucine, valine, methionine, and threonine, and be given L-carnitine.

对伴有同型半胱氨酸血症患儿，治疗以维生素B12、甜菜碱和左旋肉碱为主；对不伴有同型半胱氨酸血症患儿以限制天然蛋白质摄入，给予去除异亮氨酸、缬氨酸、甲硫氨酸和苏氨酸的特殊奶粉及左旋肉碱治疗为主。

In this open study we investigated the correlation between seminal carnitine levels and spermatozoal function, and the effect of combined L-carnitine + L-acetylcarnitine therapy, in infertile men.

在本开放式研究中，我们研究了精液中肉碱的含量与精子质量和功能的相关性，以及复合使用左旋肉碱和乙酰左旋肉碱对治疗男性不育的疗效。

A rat model induced by injecting acetic acid into the subserosa of stomach was used.Uicer index was measured,the level of nitri oxide in serum and plasma endothelin-1(ET-1) was examined.

采用大鼠乙酸性胃溃疡模型，分别以消溃灵灌胃和左旋精氨酸、亚硝基左旋精氨酸腹腔内注射治疗7 d和14 d后，测定溃疡指数、溃疡抑制率，检测血清一氧化氮及血浆内皮素(ET-1)含量。

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。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).
