    Notes: Summary Three cases with renal angiomyolipoma in Bourneville's disease are reported. In two patients advanced renal insufficiency developed, one being treated by chronic intermittent hemodialysis. In the third patient rupture of angiomyolipoma with severe retroperitoneal bleeding occurred. In one patient, tumorous enlargement initially was diagnosed only in the right kidney and preceded angiomyolipoma of the left kidney for several years. In this patient nephrectomy was performed because malignancy was assumed before diagnosis of Bourneville's disease was established. Occasionally, histology may suggest sarcomatous changes. However, the absence of distant metastasis and the overall long survival of patients with renal angiomyolipoma in Bourneville's disease underline the benign character of the tumor. Treatment should be conservative because surgical intervention with loss of kidney parenchyma may enhance progression to end-stage renal failure.

    Description / Table of Contents: Summary A patient with severe idiopathic diabetes insipidus, complicated by diabetes mellitus, was first treated with a combination of clofibrate and chlorpropamide. Urine volume dropped from 18 litres/day ( $$C_{H_2 O} $$ =10.5 ml/min) to 3.1–5.1 litres/day ( $$C_{H_2 O} $$ =-0.1-+1.1 ml/min) under treatment. Ten months after the beginning of therapy treatment was maintained with chlorpropamide alone; no significant rise in urine volume was observed. After 18 months when therapy was stopped for 5 days urine volume rose to 11.7 litres/day maximum ( $$C_{H_2 O} $$ =6.6 ml/min). No obvious side effects occurred under treatment during a follow up for over 18 months. Serum levels for arginine vasopressin before and under treatment were below 1.0 pg/ml. Determination of free water clearance ( $$C_{H_2 O} $$ ) proved to be a highly sensitive and simple method for follow up controls. It is discussed whether the coincidental manifestation of diabetes insipidus and diabetes mellitus may be caused by a single molecular lesion. This hypothesis is supported by data which imply that in both diseases chlorpropamide acts via a common molecular mechanism, the blocking of endogenous prostaglandin E2 biosynthesis. Finally a treatment with oral “non-hormonal” drugs like clofibrate and chlorpropamide should be taken into consideration in some cases of diabetes insipidus as is demonstrated by this case report.
    Notes: Zusammenfassung Ein Patient mit schwerem idiopathischem Diabetes insipidus, assoziiert mit einem zuvor manifesten Diabetes mellitus, wurde zunächst mit einer Kombination von Clofibrat und Chlorpropamid behandelt. Unter Therapie sank die Urinauscheidung von 18 Litern/Tag ( $$C_{H_2 O} $$ =10,5 ml/min) vor auf Werte von 3,1–5,1 Litern/Tag ( $$C_{H_2 O} $$ =-0,1-+1,1 ml/min) unter Therapie. Zehn Monate nach Therapiebeginn wurde mit Chlorpropamid alleine weiterbehandelt, ohne daß ein signifikanter Anstieg des Urinvolumens festgestellt wurde. Bei einem Therapieauslaßversuch kam es nach 18 Monaten zu einem Anstieg des Urinvolumens auf maximal 11,7 Liter/Tag ( $$C_{H_2 O} $$ =6,6 ml/min). Während der gesamten Therapiedauer wurden keine Nebenwirkungen beobachtet. Serumwerte für Argininvasopressin lagen vor Therapiebeginn und unter Therapie sämtlich unter 1,0 pg/ml. Die Bestimmung der freien Wasserclearance ( $$C_{H_2 O} $$ ) erwies sich als ein empfindlicher Parameter zur Therapiekontrolle. Es wird diskutiert, ob der gleichzeitigen Manifestation von Diabetes insipidus und Diabetes mellitus eine Störung der endogenen Prostaglandin E2 Biosynthese zu Grunde liegen könnte; deren Hemmung in Pankreas und Niere wird als gemeinsamer molekularer Mechanismus für die Wirkung von Chlorpropamid bei beiden Erkrankungen angesehen. Anhand der vorliegenden Kasuistik wird dargelegt, daß in bestimmten Fällen von Diabetes insipidus eine Therapie mit oral wirksamen „nicht-hormonellen“ Pharmaka wie Clofibrat und Chlorpropamid erwogen werden sollte.

    Notes: Abstract Intercalating agents, some of them in clinical use, were tested for their ability to inhibit the hepatitis B virus specific DNA polymerase reaction. Ethidium bromide was shown to be the strongest inhibitor among the compounds tested. Compounds in clinical use inhibited the DNA polymerase test only at high concentrations. The inhibitory activity of all compounds tested was increased when the MgCl2 content in the reaction mixture was lowered. UV absorption studies presented no evidence that this effect was due to complex formation of magnesium and the individual compounds. The therapeutic significance of these findings is not certain and needs further work.
