The biochemical and physiological effects of Pb~(2+) on conchocelis of Porphyra yezoensis was lower relatively, at the beginning, the algae still grew under the condition of higher concentration-40 mg/L, mannite content and POD activity appeared a tendency to first increased and then decreased, but chlorophyll a content declined slightly, on the contrary, MDA content went up quickly.

Pb~(2+)对条斑紫菜丝状体的毒性相对较弱，在浓度40 mg/L时，处理早期(12h时)丝状体仍有生长，此浓度下藻体的甘露醇含量和POD活性均随处理时间的延长呈现先升后降的趋势，而叶绿素a含量逐渐下降，与此相反，丙二醛含量迅速上升。

毒素是许多亲和性植物病原菌致病过程中产生的次生代谢产物，离体使用可造成相应的寄主表现坏死斑反应，因此是病原菌的毒性因子，对决定病原菌的致病性有很重要作用。

The December issue reports that stage 3 to 5 CKD is found in 4% to 5% of the adult population in the United Kingdom, most often in elderly individuals who have comorbidities for which they are prescribed several drugs. The authors remind practitioners that patients with impaired renal function have decreased drug clearance by the kidney and may be more susceptible to certain nephrotoxic drugs. They advise:"Whenever possible, should take steps to minimize these risks, by avoiding the drugs, using reduced doses or administrative frequency, or increasing the monitoring of renal function" by measuring estimated glomerular filtration rate.

12月号的报导刊载了英国人口中，有4%至5%是CKD第3至5级，大部分是老年人，且这些病患经常使用多种药物；作者提醒执业医疗人员，肾脏功能不全病患其肾脏排除药物的清除率下降，而且更可能受到某些具有肾毒性药物的伤害；他们建议，当情况允许时，执业人员应该将这些风险降到最低，透过避免使用部分药物，或是降低剂量、或频次，或是增加监测肾丝球廓清率的频率来评估肾脏功能。

The toxical effects of nonylphenol ethoxylates and nonyiphenol were studied with EROD in liver of carp as biomarker under external condition. These two tested substances all had activation on EROD enzyme in liver of carp. Under definite range of concentrations, with the affecting rule of inhibiting at high concentration and inducing at low concentration.

在离体条件下，以鲤鱼肝脏EROD酶为生物标志物研究了壬基酚聚氧乙烯醚及壬基酚的毒性效应结果表明，在一定的浓度范围内，2种受试物对鲤鱼肝脏EROD酶均有激活作用受试物浓度对EROD酶的活性的影响规律为高浓度时抑制，低浓度时诱导。

89Sr and 153Sm-EDTMP can relief bone pain and improve patient's life quality. 153Sm-EDTMP may repress bone metastases stronger than 89Sr, and can decrease patient's serum VCA-IgA and EA-IgA level,but the blood toxity is also more serious than 89Sr.

89Sr和153Sm－EDTMP对NPC骨转移病人的疼痛缓解和生活质量的提高有肯定疗效。153Sm－EDTMP对NPC骨转移灶的抑制作用明显强于89Sr，可以部分降低VCA－IgA和EA－IgA水平。153Sm－EDTMP的骨髓毒性较89Sr严重。
