查询词典 menadione

The inactivation of chironomid larvae in water supply systems was experimented with environment degradable vitamin K3,its main component 2-methyl-1,4-naphthoquinone,and their congener menadione triamintriazine bisulphite.

采用易被环境分解的维生素K3、其基本成分β-甲基萘醌和同系物三氨基三嗪甲萘醌亚硫酸盐，对在给水系统中出现的4龄摇蚊幼虫进行了杀生实验。

This finding may be useful for clinical application of menadione when combined with ionizing radiation to treat cancers.

此种治疗顺序的差别导致癌细胞死亡率的差异，可能有助於维生素K3在合并治疗上的应用。

Purpose: To study the killing effects of menadione alone or combined with ionizing radiation on human hepatoma Hep3B cell.

目的：本研究的目的在探讨维生素K3单独或并用游离辐射对於人类肝癌Hep3B细胞之杀伤作用。

Rats in the treatment group received intraperitoneal injection of menadione (10 mg/2 ml) once a week for four times; the control group received 2 ml water instead.

治疗组的大鼠每星期接受一次menadione 10 mg/2 ml，腹腔注射，共四次；而对照组於同时间只接受2 ml蒸馏水腹腔注射。

Using a rat transplantable hepatoma model, we have evaluated the cytotoxic activity of menadione in hepatoma cells.

本实验我们利用—大鼠肝肿瘤细胞株来观察menadione於生物体外及生物体内对肝肿瘤细胞生长的抑制能力。

In the future, next step will be find out the key molecular proteins that regulate p21 expression and complete the whole view of mechanism by low concentration of menadione .

而在调控p21基因表现的调节者部分，虽然没有进一步发现，但也让我们在未来可以朝此方向将menadione诱发p21基因表现的途径呈现更完整。

The paper presents a study of the inhibitory effects on the growth of Marine Chlorella and toxicity on the luminescent bacteria of Menadione Piperazine Bisulphite and Menadione Triaminotrizine Bisulphite.

研究了哌嗪甲萘醌亚硫酸盐和三氨基三嗪甲萘醌亚硫酸盐对海水小球藻的抑制作用以及对发光细菌毒性试验分析。

In our study, we found menadione has anticancer potential on human breast adenocarcinoma MDA MB 231 by weather cell cycle arrest, anti proliferation, or apoptosis. Low concentration of menadione (5.8μM) significant inhibited growth curve on breast cancer cells (MDA MB 231) but not breast cells (MCF 10A) by performing MTT and trypan blue cell counting. RT-PCR and western blotting showed menadione increase p21 gene and protein expressions but decrease cyclin E and CDK2 protein expression resulting in cell cycle G0/G1 arrest by flow cytometry.

MTT及生长曲线的实验，发现menadione在低浓度且长时间作用情况下，对在於人类乳腺上皮细胞癌(MDA-MB 231)是有明显的抑制作用，而在正常乳腺细胞(MCF-10A)则没有影响，在分子转录上及蛋白质表现方面也发现低浓度menadione处理24时能使MDA-MB 231诱发p21基因及蛋白表现量增加及cyclin E、CDK2抑制，再经由流式细胞仪分析也发现低浓度 menadione 处理24小时能使MDA-MB 231细胞周期GO/G1比例上升，造成细胞周期停滞，进而抑制细胞生长。

Methyl—1,4-naphtho-quinones,including phylloquinone(K1),menaquinones(K2),and menadione(K3). K1 is found in many green leafy vegetables. K2 is produced by a vast array of intestinal bacteria in human body. Menadione (K3) is not considered a natural vitamin K ,but rather a synthetic analoque acts as a provitamin .

Vitamin K是脂溶性维生素，以结构的不同分成K1、K2、K3，其中K1来自日常饮食中的绿叶蔬菜，K2来自肠道中之细菌合成，而K3则是合成维生素，维生素主要功能为催化肝脏合成凝血因子prothrombin促进凝血机制。
