Prognosis of non-Hodgkin's lymphomas in the Dresden district with special reference to combined radio-/chemotherapy

The total population affected with non-Hodgkin's lymphoma and treated by means of radiotherapy or combined radio-chemotherapy between 1960 and 1985 at the Medical Academy Dresden was analysed as to prognosis. 247 patients were classified according to the previous German scheme, 79 were subdivided on the basis of the recommendations laid down in the Kiel classification. The remission rates and survival curves achieved will stand out the comparison with international literature (remission rates of the low malignancy group amounted to 85.3 p.c. and those of the high malignancy group to 80.0 p.c.; the 5-years survival rates of the low malignancy group amounted to 61.9 p.c. and those of the high malignancy group to 41.7 p.c.). The influence of histology, clinical stage and involvement of organs is discussed on the basis of our results and informations obtained in literature. Our analysis confirms the high importance which must be attached to a common radiologic-internal outpatient-department for co-ordinating the diagnostic and therapeutical programme.     

Experimental chemotherapy of radiation injury with synthetic lysophospholipid analogs in mice

Synthetic lysophospholipids represent a variety of analogs of the naturally occurring 2-lysophosphatidylcholine. Some of these compounds showed significant therapeutic effects on the survival of mice following radiation injury when administered after various doses of whole-body X irradiation. Such therapeutic effects were discernible even when the treatment was given 6 hr after irradiation, and both intravenous and oral application were effective. Intravenous application of 2 X 25 mg/kg lysophospholipid after whole-body X irradiation around the LD50 resulted in significantly higher numbers of surviving animals. The mode of action remains speculative.     

A comparison of polyclonal antisera to pregnanediol 3 alpha glucuronide obtained from three different rabbits and their use in ELISA

The variation in the estimates of urinary pregnanediol glucuronide obtained by ELISA with 12 polyclonal antisera has been assessed. Of the 12 antisera, eight gave values comparable with each other and could be used interchangeably in the ELISA. Thus a large stock of polyclonal antibody which gave consistent values was generated and can now be used in diagnostic ELISA over a long period of time. This procedure is more economical than the development of monoclonal antibodies for the same purpose.
