摘要:

Following demineralization, the inorganic-crystalline and the organic crystalline stone material is separated into analogous fractions by a procedure used with urinary colloids. Fractions with molecular weight over or about 10,000 constitute a constant percentage of the matrix. The combination of silver nitrate staining and precipitation of fluorescent-labeled antibodies could demonstrate that the active part of the matrix is represented by the R-l fraction, the urine specific mucoprotein.

摘要:

In der vorliegenden Arbeit wird über die Messung intrazellulärer Potentiale bei gesunden und urämischen Versuchstieren berichtet. Die Messungen an der Muskulatur des Rattenoberschenkels ergaben bei gesunden Tieren Mittelwerte von 86,6 mV. Bei urämischen Tieren waren die Werte für die Membranpotentiale mit 59,4 mV stark erniedrigt. Nach Injektion von 3-Phosphoglyzerat-Natrium und α-Glyzeratphosphat-Natrium stiegen die Werte um etwa 10 mV wieder an, was mit einer direkten Förderung des Stoffwechsels der energiereichen Phosphate in Zelle bzw. Membran und einer damit verbundenen Aktivierung der Ionenpumpen sowie der nach Injektion der Natriumsalze der phosphorylierten C-3-Körper auftretenden hohen Natrium-Konzentrationen erklärt wird.

摘要:

The determination was carried out with colorimetric methods of 3-indol-acetic acid (IAA) and 5-hydroxy-indolacetic acid (5HIAA) in the urine of patients suffering from vesical neoplasia and control subjects before and after load with tryptophan. No difference was noted in the elimination of 5HIAA in the two groups. On the other hand, it was found that the subjects with vesical neoplasia eliminate, on an average, a larger quantity of IAA in the urine, in particular, in these patients the elimination of the conjugated amount of IAA appears increased, so that the ratio free IAA/ conjugated IAA diminishes. After dosing with tryptophan, there are no changes in the elimination of 5HIAA in either of the two groups, while there is a marked increase in the elimination of IAA in all the patient. After dose also the free IAA/conjugated IAA ratio is smaller in the subjects with vesical neoplasia. Finally, for two subjects of the latter group, the values of the elimination of IAA before and after dose are considerably different from the average figures.

摘要:

Nine (9) cases of ureterovaginal fistula and 4 of ureteral stenosis occurred in a series of 92 Wertheim-Meigs operations for cervical cancer (stages I and II). Only 4 patients had been previously irradiated. Treatment consisted of direct ureteral reimplantation, Boari or Boari-Gil Vernet operation and bilateral uretero-ileocystoplasty. A follow-up of 1 to 4 years was made. It is believed that patients undergoing the Wertheim-Meigs operations should later be submitted more frequently to urological X-Ray examinations, for pelvic fibrosis can continue for some time after operation, involving one or both ureters.

摘要:

The authors present a study on the structure of the bladder and the vesical part of the urethra in the adult male and female, in the new-born child, and in embryos, the study including macroscopic and microscopic dissection and histological examination. The results are compared to clinical experience. The importance of the musculus trigonalis as a factor in the functioning of the ureteral orifices and the internal urethral orifice is discussed. The authors succeeded in demonstrating the non-existence of an anatomical sphincter vesicae. Based on the results of the present study and the experience on the topic up to now it seems justified to conclude that the closing mechanism of the bladder works only in response to the basic tonicity of the smooth musculature and the elastic fibrils surrounding the internal urethral orifice and localized to the prostatic urethra or the female urethra.
