Experiments on the metabolism of nucleic acids have shown that N- formyl-sarcolysin(N-F)may reduce the content of DNA both in normal animal tissues and in transplantable tumors.In view of these findings,the effect of N-F upon p~(32) incorporation into nucleic acids was investigated,and this was compared with the effect of sarcolysin. Mice and rats were used in the experiments.Fifteen μc of P~(32) in the form of Na_2HP~(32)O_4 solution were injected intraperitoneally into the animals 24 hours after the last dose...

Experiments on the metabolism of nucleic acids have shown that N- formyl-sarcolysin(N-F)may reduce the content of DNA both in normal animal tissues and in transplantable tumors.In view of these findings,the effect of N-F upon p~(32) incorporation into nucleic acids was investigated,and this was compared with the effect of sarcolysin. Mice and rats were used in the experiments.Fifteen μc of P~(32) in the form of Na_2HP~(32)O_4 solution were injected intraperitoneally into the animals 24 hours after the last dose of N-F.The animals were sacrificed 5—6 hours after the isotope injection, RNA and DNA were isolated by the procedure described in our previous paper.Sam- ples were plated and their radioactivities were counted,and the results obtained were expressed according to the method of Davidson and Freeman. The results indicate that N-F(80mg/kg)and sarcolysin(10mg/kg)administered once daily for 4 consecutive days inhibited markedly the incorporation of P~(32) into RNA and DNA of the spleens in normal rats and in mice bearing Ehrlich ascites car- cinoma.A marked depression of P~(32) incorporation into DNA of Yoshida ascites sar- coma was also noted when N-F was administered orally at 50 or 160 mg/kg,and sarco- lysin at 5 or 20mg/kg respectively for 2 consecutive days.However,these two drugs failed to produce any significant depression of P~(32) incorporation into RNA.It is very interesting that N-F produced marked depression of P~(32) incorporation into both RNA and DNA of Yoshida solid tumors with three doses of 160 mg/kg,while with a single dose of 160 mg/kg only depression of incorporation into DNA was observed.N-F had no effect upon P~(32) incorporation into the RNA and DNA in mice bearing Ehrlich solid tumors at daily doses of 50 or 100 mg/kg for 7—9 days,as well as in mice bearing reticulo-sarcoma L_2 at daily doses of 50 or 80 mg/kg.However,under the same con- ditions N-F and sarcolysin inhibited markedly the incorporation of P~(32) into DNA of the Ehrlich ascites cells.It thus appears that N-F and sarcolysin exert a similar pattern of influence upon nucleic acid metabolism.

本文报告 N-甲对 P~(32)参入正常及肿瘤组织(或细胞)中核酸的影响。N-甲在治疗剂量下对 P~(32)参入大鼠吉田肉瘤(腹水及实体型)及小鼠艾氏癌腹水型的肿瘤细胞(或组织)核酸有明显抑制作用,且以对参入 DNA 的影响最强。N-甲对 P~(32)参入小鼠艾氏癌实体型肿瘤组织核酸无影响;在小剂量下对 P~(32)参入小鼠网织细胞肉瘤组织核酸亦无明显影响。N-甲对 P~(32)参入正常及肿瘤动物脾脏核酸有明显抑制作用。N-甲与溶肉瘤素对 P~(32)参入正常及肿瘤组织核酸的影响类似,但在等毒性剂量下其作用较溶肉瘤素稍弱。

From assuming that the distribution of electro-magnetic fields in near field region of human's muscle was consistent with modes of applicators the formulas of approximately computing SAR (Specific Absorption Rate) for the rectangular waveguides with TE10 mode (TE10 mode for short) and circular waveguides with TE11 made (TE11 mode for short) were derived by method that electric field intensity was averaged in the integrating interval. The formulas may be used in computing therapeutic dose of the micromave...

From assuming that the distribution of electro-magnetic fields in near field region of human's muscle was consistent with modes of applicators the formulas of approximately computing SAR (Specific Absorption Rate) for the rectangular waveguides with TE10 mode (TE10 mode for short) and circular waveguides with TE11 made (TE11 mode for short) were derived by method that electric field intensity was averaged in the integrating interval. The formulas may be used in computing therapeutic dose of the micromave power and evaluating efficiency of two previous kinds of applicators with various parameters. For an applicator with an 13 xxxxxxxxxxxxxx13cm2 aperture, at a frequency of 915MHz and for a TE10 mode the values of SAR under 1cm fat layer were calculated by the formula given in this paper. The calculated results agree very closely with experimental data given in the reference [1].

This paper presents optical Fourier transforms having been used to measure wavelengths and orientation of sea waves in the Jasin area of the North Sea, that is located approximately 200 km north-west of Scotland. Input films were obtained from a synthetic aperture radar (SAR) borne on a satellite. The research work was carried out in Blackett Laboratory, Imperial College of Science and Technology, using optical Fourier transform equipment. The Institute of Ooeanographio Science provided us with SAR films as well as a grant partly. Comparing the results obtained from direct measurement on the sea, or using the computer to calculate optical Fourier transforms of the input films of sea waves, with that obtained from our method, it is obvious that this method is quicker and more reliable.
