    Notes: Summary The respective rôles of arterial blood pressure and metabolic control in different stages of diabetic nephropathy were analyzed retrospectively in 52 sequentially-followed Type 1 (insulin-dependent) diabetic patients. A negative correlation was found between median post-prandial blood glucose and median duration of diabetes until onset of persistent proteinuria (p〈0.01). Systolic blood pressure was higher in patients who subsequently developed persistent proteinuria than those who did not (140 versus 121 mmHg; p〈0.05), but duration of the interval until onset of persistent proteinuria was not related to blood pressure. After onset of persistent proteinuria, hypertensive diabetic patients developed elevated serum creatinine concentrations more frequently than normotensive diabetic patients (67% versus 14%, p〈0.05). In these patients, the delay until elevation of serum creatinine concentration was negatively correlated with blood glucose (p〈0.01). Once serum creatinine was raised, decay of renal function occurred faster in patients with persistent than intermittent hypertension (p〈0.05). No effect of metabolic control was demonstrable at this stage of nephropathy. It is concluded that metabolic control determines the early course of diabetic nephropathy, whereas blood pressure is more important in advanced stages of nephropathy.

    Notes: Summary Decline of kidney function with time and its influencing factors were investigated in the present longitudinal study in Type 2 (non-insulin-dependent) diabetic patients with clinical diabetic nephropathy. Compared to a control group of Type 2 diabetic patients without proteinuria, the proteinuric patients showed a higher prevalence of hypertension, higher systolic blood pressure values and serum triglyceride levels. The annual loss of glomerular kidney function was much higher in the proteinuric patients (5.3 ml·min−1·1.73 m2) than in the control subjects (0.9 ml·min−1·1.73 m2). Correlation analyses revealed a close correlation between the annual decrease of kidney function and the factors, systolic and diastolic blood pressure, triglyceride and postprandial blood glucose level as well as body mass index. Regression analyses showed for the first time that in addition to the systolic blood pressure and metabolic control, the triglyceride level is also an independent factor influencing the progression of nephropathy. Higher values of these parameters were associated with a more rapid deterioration of kidney function.

    Notes: Summary Since second-generation (Nisei) Japanese Americans are prone to develop the insulin resistance syndrome, younger third-generation (Sansei) Japanese Americans from a cross-sectional 10 % volunteer sample of Sansei men (n=115) and women (n=115) 34 years or older in King County, Washington with normal glucose tolerance or IGT were examined for metabolic and adipose risk factors associated with this syndrome. After an overnight 10-h fast, blood samples were taken for measurement of glucose, insulin, C-peptide, lipids, and lipoproteins, followed by a 3-h 75-g oral glucose tolerance test with blood samples taken for glucose, insulin, and C-peptide measurement. BMI (kg/m2), skinfolds, and body fat areas (by computed tomography) were measured. IGT was diagnosed in 19 % of the men and 31 % of the women. Men with IGT had more adiposity, both overall and in thoracic and visceral sites, had higher fasting plasma insulin and C-peptide, and tended to have higher fasting triglyceride and lower HDL cholesterol than men with normal glucose tolerance. Women with IGT had more thoracic subcutaneous fat and intra-abdominal fat and lower fasting HDL cholesterol than women with normal glucose tolerance, and tended to have higher fasting triglyceride and LDL cholesterol. Women with IGT also had higher fasting plasma insulin than women with normal glucose tolerance but tended to be less hyperinsulinaemic than men. Differences in fasting insulin, C-peptide, and lipids were best predicted by intra-abdominal fat. Thus metabolic (higher fasting insulin and a tendency to higher triglyceride and lower HDL cholesterol) and adipose (visceral adiposity) risk factors associated with the insulin resistance syndrome are identifiable among Sansei men and women with IGT, who may therefore be at increased risk of future development of NIDDM and CHD.

    Notes: Summary Increased oxidative stress and subsequent activation of the transcription factor NF-kB has been linked to the development of late diabetic complications. To determine whether oxidative stress dependent NF-kB activation is evident in patients with diabetic nephropathy we used an Electrophoretic Mobility Shift Assay based semiquantitative detection system which enabled us to determine NF-kB activation in ex vivo isolated peripheral blood mononuclear cells. We examined 33 patients with diabetes mellitus (Type I and Type II). Patients with diabetic nephropathy showed higher NF-kB binding activity in Electrophoretic Mobility Shift Assays and stronger immunohistological staining for activated NF-kBp65 than patients without renal complications. NF-kB binding activity correlated with the degree of albuminuria (r = 0.316) and with thrombomodulin plasma concentrations (r = 0.33), indicative for albuminuria associated endothelial dysfunction. In a 3 day intervention study in which 600 mg of the antioxidant thioctic acid (α-lipoic acid) per day were given to nine patients with diabetic nephropathy oxidative stress in plasma samples was decreased by 48 % and NF-kB binding activity in ex vivo isolated peripheral blood mononuclear cells by 38 %.

    Description / Table of Contents: Summary A method is described by which glomeruli can be isolated with the aid of sieves of varying mesh within 30 min. The isolated glomeruli are obtained as an almost pure fraction (contamination 5% tubuli) and showed a constant metabolic activity over a period of 2 1/2 hour, which was demonstrated by the linear O2-consumption,14CO2-production, and incorporation rates of14C from U-14C-glucose into the basement membrane. After incubation, the basement membranes can be easily isolated by sonification. The basement membranes were controlled by electron microscopy. This method allows metabolic studies on basement membranes.
    Notes: Zusammenfassung Es wird eine Methode beschrieben, mit der Glomerula mit Hilfe von Sieben verschiedener Maschenweite innerhalb von 30 min aus Rattennieren isoliert werden können. Die erhaltenen Glomerula sind fast rein (5% Verunreinigung durch Tubuli) und zeigen über mindestens 2 1/2 Std eine konstante Stoffwechselaktivität. Dafür sprechen der lineare O2-Verbrauch, die14CO2-Produktion aus U-14C-Glucose und der lineare Einbau von14C aus U-14C-Glucose in die Basalmembran. Die Basalmembranen können nach der Inkubation mit Ultraschall leicht von den Glomerula abgetrennt werden und sind bei elektronenoptischer Kontrolle weitgehend rein. Die Methode gestattet es, Stoffwechseluntersuchungen auch an der Basalmembran durchzuführen.

    Description / Table of Contents: Summary The glomerular basement membrane of the rat is a glycoprotein with a carbohydrate content of about 10%. The neutral sugars were composed of glucose, galactose, mannose, and fucose in the molar ratio of 1:1:1,5:0,4. Sialic acid and fucose were found to be present in a molar ratio of 1:2. The hexosamines consisted of both glucosamine and galactosamine in a ratio of about 1:2 (total amount 2.1%). The lipid content accounted for about 6.5% of the dry weight (62% phospholipids, 26% triglycerides, and 12% cholesterol). The peptide portion of the basement membrane is characterized by the occurence of large amounts of proline, hydroxyproline, and hydroxylysine, suggesting a close relationship to collagen. Together with in vitro studies of the metabolic activity of isolated glomeruli a chemical analysis of the basement membrane under various conditions is believed to be a new and promising approach to the elucidation of the pathogenesis of diabetic microangiopathy.
    Notes: Zusammenfassung Die glomeruläre Basalmembran der Ratte ist ein Glykoproteid mit ca. 10% Kohlenhydraten. Bei diesen handelt es sich um Glucose, Galaktose, Mannose und Fucose in einem molaren Verhältnis von 1:1:1,5:0,4. Für Sialinsäuren und Fucose liegt dieses Verhältnis bei 1:2. Die Hexosamine bestehen aus Glucosamin und Galaktosamin im Verhätnis von rund 1:2 (Gesamthexosamine 2,1%). Der Lipidanteil beträgt ca. 6,5% (62% Phospholipide, 26% Triglyceride, 12% Cholesterin). Der Eiweißanteil ist durch das Vorhandensein von Prolin, Hydroxyprolin und Hydroxylysin charakterisiert. Die Basalmembran besitzt damit eine enge Verwandtschaft zum Kollagen. Die hier angewandten Methoden machen Stoffwechseluntersuchungen am isolierten Glomerulum und seiner Basalmembran möglich. Sie stellen unserer Ansicht nach einen neuen Weg zum Studium der Pathogenese der diabetischen Mikroangiopathie dar.

    Description / Table of Contents: Zusammenfassung Bei 81 Patienten mit tiefen venösen Thrombosen der unteren Extremität wurde eine Fibrinolysebehandlung mit Urokinase nach einem neuen, höher dosierten Therapieschema in Kombination mit Heparin durchgeführt. Unter Gabe einer Urokinasedosis von 1000–2000 IE/kg/h (Initialdosis 150000–250000 IE) konnte bei frischen, bis zu 10 Tage alten Thrombosen eine komplette oder Teileröffnung bei 68% der Patienten erzielt werden. Dabei zeigte die höhere Urokinasedosierung im Beckenvenenbereich mit einer Wiedereröffnungsrate von 67% im Vergleich zur niedrigeren Dosis mit einer Rekanalisierungsrate von nur 43% einen deutlich stärkeren thrombolytischen Effekt. Bei den Thrombosen im V. poplitea- oder Wadenvenenbereich konnte dagegen mit einer Befundbesserung von 80 und 78% bzw. 75 und 62% ein nur gering differierender Behandlungserfolg beobachtet werden. Die Ergebnisse weisen darauf hin, daß die hier angewendete höhere Urokinasedosierung (Erhaltungsdosis 2000 IE/kg/h) der niedrigeren bei Vorliegen langstreckiger Thrombosen überlegen ist. Unter der höheren Dosierung richtete sich die weitere Urokinasedosis nach der Fibrinogenkonzentration nach Clauss, wobei ein Wert von 50–100 mg% angestrebt wurde und ein Wert von 50 mg% nicht unterschritten werden sollte. Die Steuerung der Therapie gestaltete sich dabei problemlos. An Nebenwirkungen wurden bei 8,6% der Patienten Makrohämaturien und nur in 6% der Fälle ein Hb-Abfall von mehr als 2 g% beobachtet. Lebensbedrohliche oder cerebrale Blutungen traten nicht auf. Der hohe Anteil älterer Phlebothrombosen und die dann wesentlich geringeren therapeutischen Erfolgsaussichten (Rekanalisierung in nur 23% der Fälle) unterstreichen die Notwendigkeit einer möglichst frühzeitigen Klinikeinweisung.
    Notes: Summary In 81 patients with deep vein thrombosis of the lower limb, urokinase therapy was performed in combination with heparin according to a new regimen at higher dosages. When urokinase was administered at an initial maintenance dosage of 1,000–2,000 IU/kg/h (loading dose 150,000–250,000 IU), phlebographically documented complete or partial recanalization could be observed in 68% of the cases. The higher dosage schedule induced a more pronounced deobliteration expecially in treatment of iliac vein thromboses (67% recanalization) in comparison to the lower dosage regimen (only 43% recanalization). Nearly comparable therapeutic results could be achieved in therapy of popliteal or saphenous vein thromboses. The data suggest that the higher dosage schedule examined here is indicated in treatment of extensive and large volume thromboses. The dosage of urokinase was further adjusted to attain a reduction of fibrinogen to 50–100 mg/dl. The concentration should not fall below 50 mg/dl. Therapy with urokinase proved practicable. Serious side effects did not occur. 8.6% of the patients showed hematuria and 6% a decrease of the Hb by more than 2 g/dl. The high proportion of older thromboses and the only low rate of recanalization (23%) in these cases suggest the necessity of an early commencement of fibrinolyses in therapy of deep vein thrombosis.

    Description / Table of Contents: Zusammenfassung Bei 18 Patienten mit einer Achselvenenthrombose wurde eine fibrinolytische Therapie mit Urokinase in Kombination mit Heparin durchgeführt. Der thrombolytische Effekt war dabei eindeutig vom Alter der Thrombose und der Höhe der Urokinasedosis abhängig. Unter Gabe einer anfänglichen Erhaltungsdosis von 1000–2000 IE/kg/h (Initialdosis 150 000–250 000 IE Urokinase) in Kombination mit Heparin (15–17 E/kg/h) konnte bei neun der 11 Patienten (82%) mit frischen Thrombosen ein nahezu kompletter Behandlungserfolg erzielt werden. Bei einem Thrombusalter von mehr als 10 Tagen war keine phlebographische Befundänderung nachweisbar. Wesentliche Nebenwirkungen wurden nicht beobachtet. Auf Grund der hier mitgeteilten Behandlungsergebnisse sollte bei frischen Thrombosen der V. subclavia oder axillaris eine thrombolytische Therapie mit Urokinase durchgeführt werden. Der hier vorgelegte Erfahrungsbericht erlaubt darüber hinaus generelle Rückschlüsse zur Dosierung und Wirksamkeit der fibrinolytischen Substanz Urokinase.
    Notes: Summary In 18 cases with primary subclavian-axillary vein thrombosis fibrinolytic therapy was performed with urokinase in combination with heparin. The thrombolytic efficacy clearly depended on the thrombus age and the dose of urokinase applied. Under treatment with a median initial maintenance dosage of urokinase of 1,000–2,000 IU/kg/h (loading dose 150,000–250,000 IU urokinase) in combination with heparin (15–17 U kg/h) in nine of 11 patients (82%) with recently developed (8 days or less) thrombosis, a nearly complete deobliteration of the venous system was observed. In the cases with thrombosis of more than 10 days no alteration of the venous occlusions could be seen. Relevant side effects did not occur. Our results emphasize urokinase therapy of acute subclavian-axillary vein thrombosis and permit general inferences concerning the efficacy and the dosage requirements of the thrombolytic substance urokinase.

    Description / Table of Contents: Summary The influence of D-, DL- and L-glyceraldehyd on the incorporation of labeled glycine into cell protein, on O2 consumption, anaerobic and aerobic glycolysis was studied in Ehrlich-ascites tumor cells. D- as well as DL- and L-glyceraldehyd markedly inhibited the incorporation of glycine into tumor cell protein. The fact that this inhibition was much stronger under anaerobic than under aerobic conditions made it possible that the inhibition of amino acid incorporation was depending on the reduction of glycolysis by L-glyceraldehyd, known from literature. Surprisingly an inhibition of glycolysis by DL- and D-glyceraldehyd was found in concentrations of 0,005 to 0,01 mol/l. Oxygen consumption in aerobic experiments is only reduced as a consequence of impairment of aerobic glycolysis. Although in concentrations between 0,005 and 0,01 mol/l there is practically no more amino acid incorporation, while some glycolytic activity remains intact, the inhibition of glycolysis should be concerned as primary effect of glyceraldehyd, the inhibition of protein synthesis being dependant on the latter.
    Notes: Zusammenfassung Die Wirkung von D-, DL- und L-Glycerinaldehyd auf den Einbau markierten Glycins in das Zelleiweiß sowie auf Atmung, anaerobe und aerobe Glykolyse wurde an Zellen des Ehrlichschen Ascites-Carcinoms untersucht. Es fand sich, daß sowohl D- als auch L- und DL-Glycerinaldehyd den Einbau von Glycin in Tumorzellen hemmen. Die stärkste Wirkung hat dabei DL-Glycerinaldehyd. Die Tatsache, daß die Einbauhemmung unter anaeroben Bedingungen wesentlich stärker als bei O2-Zutritt ausgeprägt war, ließ an einen Zusammenhang mit der aus der Literatur bekannten Hemmung der Glykolyse durch L-Glycerinaldehyd denken. Überraschenderweise fand sich, daß sowohl DL- als auch D-Glycerinaldehyd die Glykolyse in Konzentrationen von 0,005–0,01 Mol/l stark unterdrücken. Der O2-Verbrauch wird — bei Versuchen unter aeroben Bedingungen — erst als Folge der Glykolysehemmung herabgesetzt. Obwohl bei Konzentrationen zwischen 0,005 und 0,01 Mol/l besonders unter anaeroben Bedingungen ein Einbau markierten Glycins in das Tumorzellprotein praktisch nicht mehr stattfindet, während bei denselben Konzentrationen eine glykolytische Aktivität immer noch nachweisbar bleibt, dürfte die Hemmung der Glykolyse als primärer, die Hemmung der Proteinsynthese als davon abhängiger sekundärer Effekt des Glycerinaldehyds anzusehen sein.
