Ca 2+ at 1 64 mmol/L markedly increased ethanol tolerance of a self_flocculating fusant of Schizosaccharomyces pombe and Saccharomyces cerevisiae. After 9 h of exposure to 20% ethanol at 30℃, no viability remained for the control whereas 50 0% remained for the cells both grown and incubated with ethanol in Ca 2+_added medium.

生长阶段和冲击阶段均添加 1 6 4mmol LCa2 +能显著提高自絮凝颗粒酵母于 30℃在 2 0 %酒精冲击下的存活率，经过 9h冲击，对照组的存活率为 0 ，而添加Ca2 +试验组的存活率为 5 0 0 %，表明添加适当浓度的Ca2 +能显著提高菌体的耐酒精能力。

The survival rates of CEM cells cultured with cis-diamminedichicloroplatinum added 24 h later were higher than that cultured with hTERT ASODN and DDP added 24 h later. The survival rates of CEM cells cultured with DDP were similar with that cultured with hTERT SOND and DDP. In morphological observation of apoptotic cells using Giemsa staining, cells treated with DDP or DDP combined with hTERT ASODN ro SODN at 48 h, displayed classic apoptotic changes. Apoptosis rates of CEM cells treated with DDP for 48 h after 24 h of exposure to ASODN significantly increased. There was significant difference in the percentage of apoptotic cells of CEM cells between hTERT ASODN plus DDP and SODN plus DDP or DDP alone, respectively.

结果： hTERT ASODN作用于CEM细胞24 h再加入柔红霉素、长春新碱、足叶乙甙，对细胞生长的抑制分别与单用柔红霉素、长春新碱、足叶乙甙及hTERT正义寡核苷酸联合柔红霉素、长春新碱、足叶乙甙组相比，统计学上无显著差异(P＞0.05)。hTERT反义核酸作用于CEM细胞24 h加入顺铂，再共同作用48 h，CEM活细胞均数为2.318×108 cells/L，与单用顺铂组(3.250×108 cells/L)及hTERT正义核酸联用顺铂组(3.175×108 cells/L)相比，对细胞抑制明显增强(P＜0.05)。hTERT ASODN作用于CEM细胞24 h再加入顺铂作用48 h，细胞出现典型的凋亡形态学改变。hTERT ASODN与2.5 μmol/L顺铂联合作用于CEM细胞48 h的凋亡细胞百分率(19.47%)分别同SODN与顺铂联合作用组(6.97%)、单用顺铂作用组(6.02%)进行比较有显著差异(P＜0.01)。

Both nickel oxide and nickel subsulfide were toxic to HEL cells after 24hr exposure at a relatively low dosage.

研究表明，二硫化三镍和氧化镍在较低剂量下均对人胚肺细胞MRC-9和IMR-90有毒性作用。

Yahoo board of directors last week after conclave of 5, the identity exposure of new co-worker AOL, in this conference, the board of directors under weigh decides accredit manages a layer, in this week and small kind times the AOL below Hua Naqi has more thorough contact, of course, this also is up to now, what Yahoo board of directors gives out to Microsoft is the clearest " signal ": Do not abandon and Microsoft ask a price, but also do not abandon other collaboration likelihood.
