However, in our functional experiment, LEM and NIC show relaxation effect in the presence of 40 or 60mM 〓. Thus it is necessary to define this criteria in exact terms, we recommended that potassium concentration higher than 80mM be used when employing the above criterium.

在功能实验中本研究结果提示，某些钾通道开放剂可舒张某一范围高钾浓度所致的血管收缩，因此，有必要对此标准进行量化，我们建议高钾浓度宜选用80mM〓以上较为合适。

Mefthods: The serum concentrations of penicillin V potassium were determined by microbiological assay in 10 healthy male volun-teers after an oral dose of 1500 mg penicillin V potassium in crossways. Data of serum leveltime were processed with 3P87 software.

以美国进口的青霉素V钾片为标准参比制剂，研究洛阳春都制药公司研制的青霉素v钾颗粒剂相对生物利用度。10名健康受试者随机交叉口服青霉素v钾被试及参比制剂各1500mg后，采用微生物法测定不同时间血清中药物浓度，用3P87软件经微机处理药-时数据。

Like any other Gramineous crop, hybrid rice keeps 80% of totally removed K in its shoots after ripening, only about 20% of K uptake is transported to grain, grain K content was more stable, usually around 0.5%.

同其它禾本科作物一样，成熟后杂交水稻保存总移出钾的80%在其茎杆中，只有20%吸收的钾转移到籽粒中，籽粒含钾量更为稳定，一般约为0.5%（表6）。

The outward rectifier K+ current current was the dominant K+ current in the whole cell currents in Deiters' cells. In the presence of 200μ M linopirdine, the Ik current was not significantly effected. Our findings demonstrated that the KCNQ heteromeric or homomeric potassium channel may be the molecular basis for the peak outward K+ current and testified that the inward IKn current is mediated by KCNQ potassium channel.

在细胞外液中，加入100 μmol/L利诺吡啶后，OHCs中的四乙基二乙胺敏感的钾电流峰电流成分被抑制，稳态电流幅值减小，且电流的失活时间常数明显延长；在细胞外液中加入100 μmol/L和200 μmol/L利诺吡啶后，OHCs的内向性钾电流IKn被完全抑制；而细胞外液中利诺吡啶终浓度为200 μmol/L 时，Deiters细胞的外向整流性钾电流幅值无明显变化。

Objective:Death caused by hyperkalemia or potassium intoxication is not rare in medicolegal expertise practice.

目的：在法医实践中，因高钾血症或钾中毒致死案例并不少见，其中又以短时内补钾过量导致医疗纠纷的案件为多。

With the improving of potassium and phosphoresce, the tendency of biological resolving was lower.

说明施入过量的钾矿粉，容易造成钾胁迫，抑制钾细菌的繁殖和矿化。

Most of small intrusive bodies are stocks or dikes, and each of the dimension is less than 1km2 ; they are mostly granite-porphyry、porphyritic-granite、monzogranite,a small amouts of them are quartz diorite or diorite; the chemical characters are high content of SiO2、K2O and low content of Mg and CaO, on the SiO2-K2O diagram all the samples fall in the field of high-K calc-alkalic series and shoshonite series.

小岩体多呈岩株或脉状产出，出露面积多数在1km2以下；岩性主要为花岗斑岩、似斑状花岗岩、二长花岗岩，少量为石英闪长岩及闪长岩等；岩石化学成份以高硅、富碱、多钾、贫镁、少钙为特征，属高钾钙碱性系列或钾玄岩系列。

The rocks are potassium-high (K2O=4.10%~5.27%, 4.86% on average) and alkali-rich (Na2O+ K2O=7.12%~8.24%, 7.85% on average) ones, and have an average K2O/Na2O value of 1.63, ACNK values of 0.90~1.05 (0.96 on average) and KN/A values of 0.71~0.89 (0.78 on average), thus belonging to metaluminous to weakly peraluminous granitoids of shoshonite series and K-high calc-alkaline series.

岩石高钾、富碱，K2O含量为4.10%~5.27%，平均4.86%；Na2O+K2O为712%~8.24%，平均7.85%；K2O/Na2O值平均为163；ACNK值在0.90~1.05之间，平均为0.96；KN/A在0.71~0.89之间，平均为0.78，属钾玄岩系列与高钾钙碱性系列准铝质－弱过铝质花岗岩类。

It was found that 0.25%o potassium sorbate produced a positive inhibition against short G+ spore bacillus with a concentration less than 5xl04cfu/ml. A concentration less than %o potassium sorbate hardly exerted a complete control towards short G- plump bacillus having a population density of 5x104cfu/ml. It was proved that use of l% potassium sorbute never controlled the growth of G+ coccus, G~ spirilla and enterobacter with a population density of 104cfu/ml. 1mmol EDTA completely controlled the growth of G+ short spore bacillus and G+ coccus whose cell density was 5xl04cfu/ml. A level of lmmol EDTA showed a limited inhibition against the growth of G- spirilla with a population density of 105 cfu/ml. However, a level of 10mmol EDTA completely controlled the growth of the G- spiral bacteria having a population density of 105cfu/ml. lOmmol EDTA produced a very significant control towards the growth of G"" plump short bacillus with 105cfu/ml. 20mmol EDTA showed a remarkable inhibition against the enterobacter with a population density of 105cfu/ml. Different concentrations of nisin including 25mg/mL, 50mg/mL, 75mg/mL and 100mg/mL were used as bio-preservative to examine its effects against the growth of all strains leading to the spoilage of fresh mutton meat. It was seen that there was a big difference in nisin's concentrations in inhibiting the spoiling bacteria. Generally speaking, as more as 75mg/mL of nisin significantly inhibited the growth of G+ short spore bacillus, G-plump short bacillus, enterobacter, G'spiral bacteria and G+ coccus having a population density of 105cfu/ml.

分别运用山梨酸钾、EDTA和Nisin对7种主要引起羊肉腐败的微生物进行了抑菌实验，结果显示，0.25‰以上山梨酸钾能够有效抑制5×10~4 cfu／mL以下的革兰氏阳性短芽孢杆菌的生长；1‰以下的山梨酸钾不能完全抑制5×10~4 cfu／mL革兰氏阴性粗短杆菌的生长，对10~4 cfu／mL革兰氏阳性球菌菌株、革兰氏阴性螺旋菌菌株和肠杆菌菌株抑制效果不太明显。1mmoL EDTA能完全抑制住小于10~5 cfu／mL革兰氏阳性短芽孢杆菌菌株、革兰氏阳性球菌菌株的生长，能明显的抑制10~5 cfu／mL的革兰氏阴性粗短杆菌菌株生长，对10~5 cfu／mL的革兰氏阴性螺旋菌菌株有一定的抑制作用。10mmoL EDTA能完全抑制住10~5 cfu／mL革兰氏阴性螺旋菌菌株的生长；能明显抑制10~5 cfu／mL的革兰氏阴性粗短杆菌菌株的生长，而20 mmoL EDTA能很明显抑制10~5 cfu／mL肠杆菌菌株的生长。25mg／mL、50 mg／mL、75 mg／mL和100 mg／mL的Nisin几乎对所有引起羊肉的腐败菌有抑制作用，但抑制程度不同，抑菌活性有一定的变化。
