[Irradiated cases of cervical and breast cancer II. Comparative investigation of the immune status of irradiated cases with stage III cancer of the cervix and operated, non-irradiated cases (author's transl)].

Eleven patients with stage-III cancer of the cervix were investigated before, during and after radio-therapy in regard to their state of humoral immunity on the basis of determinations of the serum IgG, IgM and IgA concentration, of hetero- and isoagglutinins, of tetanus antitoxin before and after vaccination with toxoid, of measles antibodies and of the percentage of lymphocyte membrane fluorescence. The cellular immunity of the same patients was investigated by determination of the percentage of spontaneously-rosetting lymphocytes, of skin-test reactivity with DNCB before and after sensitization, of skin-test reactivity with candida, trichophyton, varidase, OT and staphylo antigen. The function of polymorpho-nuclear leucocytes was investigated by means of the NVT test and St. aureus, E. coli and latex particles. All investigations were performed both before, and 3, 6, 9 and 12 weeks after the commencement of radiotherapy and the results were compared with those of an operated, non-irradiated group (stages I b and II a). Two types of noteworthy results were observed: 1. A decrease in immunological reactivity, probably in connection with cancer, since this reaction was observed both in irradiated and in non-irradiated cases, characterized by lowered or absent immune answer to tetanus toxoid, lymphopenia, decrease in sensitization to DNCB and less positive skin tests to old tuberculin and varidase. 2. An additional inhibition (although in one investigation stimulation of the immune answer was also seen), probably in connection with radiotherapy, characterized by an additional decrease in immune answer to tetanus toxoid, in skin sensitivity to DNCB sensitization and in tests with old tuberculin, and an augmented lymphopenia, as well as an increase in positive skin tests with varidase. No significant changes were observed with any other method.

[Investigations on the immune status of operated and irradiated cases of cervical and breast cancer I. immune status before and after surgery of cancer of the cervix, stages I b and II a(author's transl)].

12 patients were investigated in regard to their state of humoral immunity by means of the following determinations: IgG, IgM, and IgA concentrations in the serum, hetero- and isoagglutinins, tetanus antitoxin before and after immunization with toxoid measles antibodies and the percentage of lymphocytes with membrane fluorescence. The cellular immunity was investigated in some patients with determination of the percentage of spontaneously-rosetting lymphocytes, of the DNCB skin-test reactivity before and after sensitization with DNCB and of skin-test reactivity to candida, trichophyton, varidase, OT and staphylo antigen. The functional efficiency of polymorphonuclear leucocytes was investigated by means of the NBT test and Staph. aureus, E. coli and Latex particles. All investigations were performed before, and 3, 6, 9 and 12 weeks after surgery. 4 methods only amongst the entire spectrum employed in the investigation proved to give sufficient evidence of signs of decreased efficiency of the immune response in the investigated patients: determination of tetanus antitoxin before and after immunization, a distinct increase in titre being observed only in 5 cases, determination of the sensitization to DNCB, which was positive only in 4 cases and determination of skin-test reactivity to varidase and OT, which was found to be less frequently positive than in controls. However, all these reactions showed no evidence of any correlation to surgical management and appeared merely to reflect characteristic responses of these cancer patients. Moreover, with the exception of the decrease in lymphocytes, no changes were detected in the data obtained by the other methods used in this study which might show some reflection of an alteration in response following surgery.

[Various forms of the celiac trunk and its anastomoses with the superior mesenteric artery].

Three rare varieties of upper abdominal arteries were compared with similar cases in the anatomical literature. An attempt was made to obtain a classification of the supernumerary branches of the celiac trunk and of the anastomoses between the celiac trunk and the superior mesenteric artery. One or more supernumerary branches of the celiac artery can be observed: (1) the superior mesenteric artery; (2) an accessory hepatic artery; (3) a posterior pancreatic artery; (4) a colic artery; (5) an accessory splenic artery; (6) a connecting branch to the superior mesenteric artery, and (7) an inferior phrenic artery. The following types of anastomoses between the celiac artery and the superior mesenteric artery can be distinguished: (1) direct connection; (2) anastomoses within the hepatic artery; (3) anatomoses following pre- or postnatal stenosis, and (4) the pancreatic arcades. For the first type the theory of TANDLER (longitudinal anastomosis) is abandoned. The development of the second type is as yet unresolved. In the case of the last two types a postembryonal formation is possible.

[Accessory hepatic arteries and their nomenclatoric problems in radiology (author's transl)].

The numerous anatomical and radiological nomenclatures of hepatic arteries are compared and discussed. Our own material for the assessment of accessory hepatic arteries consisted of 220 anatomically prepared individuals and 74 angiograms. The individual branches in the normal case as well as all variations and their frequency are discussed. The present, often confusing nomenclature is critically reviewed and an attempt is made to establish a simple and clinically acceptable nomenclature. We propose to name the additional branches supplying the liver as 'arteria hepatica accessoria' with reference to the vessel from which they originate. Additional branches in the terminal branching (ramus accessorius) and vessels of the liver capsula should not be referred to as accessory hepatic arteries.

[Ozone and gynecologic radiotherapy].

A short survey is given of the historical development and the physical basis of ozone therapy. Ozone is used in medicine as well as in other spheres. Papers reporting good results of ozone treatment in carcinoma seemed of particular interest. The efficacy of ozone as an adjuvant to the irradiation of carcinosarcomas of rats was confirmed by us. On account of this fact ozone was introduced by us as an adjuvant to the irradiation of women with gynaecological cancer and appeared to give good results. The mechanism of action of ozone is not yet fully clarified and several theories are discussed. Investigations are currently being undertaken in respect to the behaviour of several substances in the organism during ozone therapy.

[Pollen diet as an adjuvans of radiotherapy in gynecologic carcinomas].

The introduction of a pollen diet as an adjuvant in the reduction of side effects during radiotherapy of patients with gynaecological cancer is described and its efficacy evaluated. 15 women with carcinoma of the cervix received a pollen diet during irradiation, whilst ten further patients receiving irradiation served as controls without pollen added to the diet. Serum enzymes, proteins, vitamins and blood count were analysed before and after irradiation. It appears, that pollen favourably influences the efficacy of irradiation and reduces the frequency of side effects, both subjectively and objectively.

[The photon-stationary-field therapy with the 42 MeV betatron using wedge filters].

The dose distribution in photon beams from a 42 MeV betatron using wedge filters of lead with different angles of slope is described. The wedge coefficient to be considered at a field size of 10 X 10 cm is given. The scope for isodoses modified by wedge filters is discussed with regard to stationary-field photon therapy.
