  fusion frequency
The fusion frequency ranged from 6.2 × 10-2-9.1 × 10-2.
      
Visual selection for callus morphology combined with a high fusion frequency and irradiation of one parental protoplast type (137Cs source, 1.5 Krads) resulted in selection of a callus clone population containing a high proportion of somatic hybrids.
      
About 20% of the protoplasts survived the fusion treatment, and the fusion frequency was 3%-4%.
      
Among cells infiltrating the graft, the fusion frequency was 1:172x103 and the frequency of Ig-producing hybrids 1:400x103 (i.e., this assay was approximately three log orders less sensitive than the reverse pA assay).
      
Investigation of the conditions, necessary to achieve this high fusion frequency, showed that supplementing the PEG solution with Ca++ and adjustment to high pH gave the best results.

The changes of some physiological and biochemical indices in soldiers were studied during successive walking on the treadmill with a back pack of about 15 kg for 3 hours, and during a 3 days field marching with the same back pack. The heart rate increased and the critical flicker fusion frequency decreased during walking, but no significant differences were observed between different walking times. The blood lactate, the contents of protein, creatinine and K~+ in urine, and the contents of K~+ and Na~+in saliva...

The changes of some physiological and biochemical indices in soldiers were studied during successive walking on the treadmill with a back pack of about 15 kg for 3 hours, and during a 3 days field marching with the same back pack. The heart rate increased and the critical flicker fusion frequency decreased during walking, but no significant differences were observed between different walking times. The blood lactate, the contents of protein, creatinine and K~+ in urine, and the contents of K~+ and Na~+in saliva increased with prolongation of walking time, meanwhile, the contents of Na~+ in urine decreased with walking time. The Scales of "rating of perceived exertion" and "category table of fatigue symptoms" were closely related to blood lactate. It suggest that the scales of "RPE" or of "category table of fatigue symptoms." may be used as an index to estimate the fatigue for soldiers during field work.

本文观察了青年战士跑台模拟3h负重行军和野外连续3天负重行军的某些生理生化参数的变化。结果表明,劳动后心率升高,闪光融合频率降低,但不同劳动时间之间无明显差别。血乳酸、尿中蛋白、肌酐和K~+以及唾液中K~+和Na~+随劳动时间延长呈增加趋势,尿Na~+呈降低趋势。“自认疲劳分级(RPE)”和“疲劳症状分类表”的打分值与血乳酸含量呈显著正相关。我们认为,在野外条件下可以采用RPE和、“疲劳症状学分类表”评价战士的疲劳。

Objective To investigate the adverse-effect of triazolam, zolpidem, and zopiclone on cognitive ability of healthy young men,so as to provide scientific basis for working out rational scheme for aircrew to use these drugs. Methods Eight male healthy young volunteers experienced a double-blind, crossover design,in which four drugs(placebo, triazolam 0.25 mg, zolpidem 10 mg and zopiclone 7.5 mg) were respectively used in four experiments arranged at intervals of 5 days.

Objective To investigate the adverse-effect of triazolam, zolpidem, and zopiclone on cognitive ability of healthy young men,so as to provide scientific basis for working out rational scheme for aircrew to use these drugs. Methods Eight male healthy young volunteers experienced a double-blind, crossover design,in which four drugs(placebo, triazolam 0.25 mg, zolpidem 10 mg and zopiclone 7.5 mg) were respectively used in four experiments arranged at intervals of 5 days. Tests including Stanford sleepiness scale, four-digit-addition, psychomotor performance, dual task, visual and auditory reaction time and motion reaction time, attention distribution, and critical flicker fusion frequency were performed 4 h before and 1 h,2 h,3 h,4 h,6 h,8 h,10 h after drug administration. The differences in cognitive ability among drugs or time points after drug administration were determined by analysis of variance. Results Zolpidem, and zopiclone could markedly elevate the scores of Stanford sleepiness scale(SSS) in comparison to placebo. The highest scores of SSS in zolpidem and zopiclone groups were 4.0 and 3.4 respectively. Zolpidem and zopiclone obviously decreased the psychomotor performance by 9.2% and 11.0% respectively.Moreover,zolpidem could obviously decrease the keeping rate of dual task while zopiclone decreased the correct rates of four-digit-addition and dual task. Triazolam had no significant influence on these parameters. Conclusion The effects of these hypnotics on cognitive ability disappeared about 6 h after drugs were taken. Triazolam has minimal side effects.
