    Notes: Summary A comparative immunocytochemical and electron microscopic study was performed on renal biopsies from two children with classical Bartter's syndrome (BS) and three children with a recently described variant, the so-called hyperprostaglandin E-syndrome (HES). Compared to age-matched controls, kidney specimens from patients with BS and HES disclosed a marked hypertrophy and hyperplasia of the juxtaglomerular apparatus (JGA). In addition, in HES focal tubular and interstitial calcifications accompanied by interstitial fibrosis and tubular atrophy were noted. On immunocytochemistry, chronic stimulation of the JGA in BS and HES was characterized by an increase in the number of renin-positive cells, particularly in the media of afferent arterioles, but also in efferent arterioles and in the glomerular stalk. The length of the renin-positive portion of the preglomerular arterioles was significantly increased when compared to controls (100±32 vs. 49±17 µm;p〈0.001). In addition, the immunoreactivity of individual renin-positive cells was markedly enhanced. On electron microscopy, “hypertrophy” of the RER and of Golgi complexes with paracrystalline deposits in dilated RER cisterns and protogranules indicated an increased renin synthesis. Renin could be identified in mature secretory granules as well as protogranules by immune electron microscopy. Angiotensinogen was present in hypertrophied epithelial cells of Bowman's capsule. Converting-enzyme reactivity was observed in controls as well as in BS and HES in the brush border of the proximal tubule. In contrast to previous reports, Angiotensin II was completely negative in control as well as in diseased kidneys. We conclude from our results that both BS and HES are characterized by a marked activation of the JGA and severe stimulation of the renin-angiotensin system. Since activation of this system, however, leads - independently of the primary stimulus - to qualitatively very similar morphological reactions, these results do not implicate a common pathogenetic mechanism to both conditions.

    Description / Table of Contents: Cobalt(II) salts react with excess diacetylmonoxime-β-pyridyl-(2)-ethylimine (DPÄ) forming complexes of the type [CoIII(DPÄ - H)2]X with X = Cl, J, NCS, NO3, ClO4, atmospheric oxygen being the oxidant. Starting with Co to ligand ratios of 1:2 and 1:1, complex salts of the types [Co(DPÄ - H)2]2[Co(NCS)4] and [Co(DPÄ - H)2] [CoCl3(C2H5OH)] · C2H5OH, respectively, are obtained. The complexing ability of DPÄ is discussed and compared with those of other oxime ligands.
    Notes: Kobalt(II)-Salze bilden bei der Umsetzung mit dem in der Überschrift genannten Liganden (DPÄ) in großem Überschuß Komplexe des Typs [CoIII(DPÄ - H)2]X (X = Cl, J, NCS, NO3, ClO4). Als Oxydationsmittel fungiert der Luftsauerstoff. Werden die Komponenten im Verhältnis 1:2 bzw. 1:1 zur Reaktion gebracht, so entstehen Komplexsalze wie [Co(DPÄ - H)2]2[Co(NCS)4] und [Co(DPÄ - H)2] [CoCl3(C2H5OH)] · C2H5OH. Das komplexchemische Verhalten von DPÄ wird mit dem anderer Oximliganden verglichen.

    Description / Table of Contents: Diacetyl monoxime-β-pyridyl-(2)-ethylimine (DPE) reacts with Ni(II) salts forming paramagnetic complexes of the type Ni(DPE)2X2 (with X = NO3, ClO4, J-). DPE behaves as a tridentate ligand. In the compounds Ni(DPE)2(SCN)2 and Ni(DPE)(SCN)2, the thiocyanate ions participate, at least partially, in the complex formation.Whereas Cu(II) ions normally form 1,1 complexes of the type Cu(DPE)Y2 with Y = Cl-, Br-, NO3, from the interaction between the perchlorate and DPE a chelate compound of the formula [Cu(DPE - H)]ClO4, probably being dimeric, results. The compounds Zn(DPE)Cl2 and Zn(DPE)J2 are non-electrolytes in acetonitrile.
    Notes: Diacetylmonoxim-β-pyridyl-(2)-äthylimin (DPÄ) bildet mit Nickel(II)salzen paramagnetische Komplexe des Typs Ni(DPÄ)2X2 (X = NO3. ClO4- und J-). DPÄ fungiert darin als dreizähliger Ligand. In den Verbindungen Ni(DPÄ)2(SCN)2 und Ni(DPÄ)(SCN)2 sind die Rhodanidionen zumindest teilweise an der Komplexbildung beteiligt. Kupfer(II)-Ionen bilden mit DPÄ die 1,1-Komplexe Cu(DPÄ)Y2 [Y = Cl-, Br- und NO3]. Nur bei der Umsetzung mit Kupferperchlorat entsteht ein, wahrscheinlich dimerer, Innerkomplex [Cu(DPÄ - H)]ClO4. Die Verbindungen Zn(DPÄ)Cl2 und Zn(DPÄ)J2 besitzen in Acetonitril Nichtelektrolytcharakter.
