[Luminal deviation of the normal pancreatic duct a post mortem x-ray study (author's transl)]

The study was performed in 64 post mortem ductograms of pancreata, missing any inflammatory and/or neoplastic alterations in extensive histological investigations by whole organ sections. The pancreatic duct was measured in the radiograms. From these measured values and by mean of a computer program of a cubic spline function the straightened pancreatic ducts were plotted. The number, the length and the amplitude of ductal deviations were measured in these plots. Luminal dilatations were found in all organs, ranging from 0.5 mm to 6 mm and more. Their frequency was significantly lowered in young people (11-30 years).

[A contribution to the early diagnosis and differential diagnosis of bladder neoplasms by means of immunological methods]

According to the present examinations it is pretty probable that already in early histological forms of the carcinoma of the urinary bladder the EM-test is able to indicate immunologically malignity, i.e. that the papillary non-infiltrating carcinoma of the transitional cell as well as the carcinoma in situ of the urinary bladder (23) also immunologically behave like tumors of the bladder. In differential-diagnostic questions concerning the organ localisation of the primary tumor the EM-test seems to give valuable references. Histologically not unequivocally malignant tumors of the bladder with positive results in the EM-test should be submitted to an exacter examination and control.
