The author's retinoscopy with a double-door type of illumination is presented in this paper. It is an objective method for the measurement of refractive errors by using an elect ic retinoscope. Spherical lens are used to neutralize the illumination from the pupil of the Patient u til the size, intensity and rapidity of movement of the double-door illumination from the pupil becomes almost identical. When a lineal back slit srace has been revealed in the middle of the double-door illumination, with a point of re(?)lex light on the center corneal surface, the neutral point is determined. The main points of using this method are also discussed in this paper.

In the present experiment, we investigated the im munoprophylactic and immunotherapeutic effects of transferring spleen LAK cells or " LAK-88/DC " cells from 615 inbred mice against mouse leukemia. The results showed that transferring LAK cells or "LAK-88/DC" cells and injecting conditional medium for a week 21 days before L615 inoculation induced significant prophylactic effects, which cured 80% of the L615-sufferring mice. Injecting conditional medium alone was also effective, which cured 60% of the mice, While transferring LAK cells or "LAK-88/DC" cells at the same time with L615 inoculation or 1 day after L615 inoculation presented no apparent therapeutic effect. However, when combined with cyclophosphamide (CY) chemotherapy, the transfer of LAK cells or "LAK-88/DC " cells 5 days after L615 inoculation could prolong the mean survival time and even cured 25%-28.6% of the advanced L615 leukemic mice.

Several photosensitive materials of Chinese make have been used for the whole- body autoradiography of the tritium labelled and freeze-drid sections of mice.1 mCi of tritiated water was injected peritoneally into each mouse.Sections prepared from the mouse were placed in direct contact with fast X-ray films for ihdustrial use,made in Tianjin.After 22 days of exposure,satisfactory autoradiographs were obtained.When the X-ray film for medical use,made in Shanghai,was tried,no satisfactory autoradi- ograph was obtained after 30 days of exposure.Besides,the dry plate prepared in our laboratory from Nuclear Emulsion №4.has also been tried,but only an incomplete outline was seen on the autoradiograph even after 124 days of exposure.
