    Description / Table of Contents: Zusammenfassung Es wird über die Anwendung der Mikroelektrophorese in Polyacrylamid-Gradientengelen zur Differenzierung der Proteinurie bei Glomerulonephritis berichtet. Die zeitlichen und methodischen Vorteile dieser Elektrophorese erlauben eine routinemäßige Durchführung in der Klinik. Durch die Auftrennung der Urinproteine nach ihrer Molekulargröße und Form lassen sich vier Proteinuriemuster unterscheiden: kleinmolekular, mittelmolekular, intermediär und hochmolekular. Glomerulonephritisformen, die konstante morphologische und klinische Veränderungen zeigen (z.B. minimal proliferierende Glomerulonephritis, mesangioproliferative Glomerulonephritis mit diffuser Halbmondbildung), lassen eine Zuordnung ihrer Proteinurie zu einem der vier Proteinuriemuster zu, während bei den anderen Glomerulonephritisformen (z.B. perimembranöse Glomerulone-phritis, mesangioproliferative Glomerulonephritis) eine Abhängigkeit des Proteinuriemusters von der Glomerulonephritisphase vermutet wird.
    Notes: Summary It is possible to differentiate the proteinuria of glomerulonephritis by means of microelectrophoresis in polyacrylamide-gradient gels. The advantages of this method (quick, cheap, concentration of the urine not required) led to its introduction into clinical use. Upon separating the urinary proteins according to their molecular weight and form, four patterns of proteinuria may be differentiated: low molecular, middle molecular, intermediate and high molecular. Those forms of glomerulonephritis which show constant morphological and clinical findings (e.g. minimal proliferative glomerulonephritis, mesangioproliferative glomerulonephritis with crescents) can be related to one of the four patterns of proteinuria, whereas the pattern of proteinuria in other forms of glomerulone-phritis (e.g. (peri-)membranous glomerulonephritis, mesangioproliferative glomerulonephritis) are dependent on the phase of the disease.

    Notes: Summary The present study was designed to determine the effects of denervation on glycoprotein synthesis in the predentinal matrix of the mouse incisor. The inferior alveolar nerve (IAN), superior cervical ganglion (SCG) or both (IAN+SCG) were unilaterally resected in adult mice with the contralateral side remaining intact as a control. Fourteen days after surgery and 4 h prior to killing, 0.2 mCi of 3H-fucose was injected intravenously and mandibles were processed for standard histological and autoradiographic techniques. Silver halide grains were counted over the predentin matrix for 2000 μm per tooth. The results showed that the IAN and SCG resection affected 3H-fucose incorporation into the predentinal matrix; however, the highest absolute mean grain counts occurred after IAN+SCG resection. SCG resection increased the amount of 3H-fucose incorporated into the predentinal matrix by 48%, that of IAN by 24% and that of IAN+SCG by 14% as compared to contralateral controls. These data indicate a regulatory role for the nervous system and a possible interaction of neural components in the control of glycoprotein synthesis by odontoblasts in the mouse incisor.
