Lipolysis in isolated epididymal adipocytes from genetically obese Zucker rat treated with 3,5,3'-L-triiodothyronine.

1990

Abstract. Glycerol released by isolated epididymal adipocytes was measured in 6-8 weeks old genetically obese (fa/fa) and lean (C.c.a/-) male Zucker rats, ip treated or not treated with T3 (0.46, 2.3 and 4.6 nmol/100 g in a single injection or 4.6 nmol · (100 g)−1 · day−1 for 5 days). In the non-treated rats, lipolysis was less stimulated by adrenalin or isoproterenol in obese than in lean rats, whereas it was stimulated by theophylline up to the same level in both kinds of rats. A single injection of the T3 (highest dose) increased isoproterenol-induced lipolysis in the lean but not in the obese rats. The 5-day T3 treatment caused a stimulation of the adrenalin- or isoproterenol-induced li…

Immobilized glycolipids from human diploid fibroblasts inhibit DNA synthesis of cultured human fibroblasts*1

1987

Several previous studies have shown that glycolipids isolated from plasma membranes of cultured cells and added to cells in culture inhibit the growth rate in a concentration-dependent fashion. In order to investigate the possible involvement of glycolipids in the growth regulation of normal cells by cell-cell contacts, we tested the effect of immobilized glycolipids, isolated from human fibroblasts, on the DNA synthesis of freshly seeded fibroblasts. Gangliosides inhibited DNA synthesis to a great extent, whereas neutral glycolipids had only a minor effect. The degree of inhibition of DNA synthesis by immobilized gangliosides depended both on the cell density of the cultures from which the…

Co-transmitter mediated facilitation by sympathetic nerve stimulation of evoked acetylcholine release from the rabbit perfused atria preparation.

1995

Rabbit atria were isolated with the extrinsic right sympathetic and vagus nerves attached and perfused with Tyrode solution. Acetylcholine overflow was determined after labelling of the transmitter stores with [14C]choline and fractionation of the radioactivity on cation exchange columns. Sympathetic nerve stimulation (SNS, 2 Hz, 3 min) carried out together with vagus nerve stimulation (VNS, 2 Hz, 3 min), but each SNS pulse preceding a vagal one by 19 ms, caused a facilitation of acetylcholine overflow of about 60% versus independent controls in the absence of SNS. Antagonists of putative neurotransmitters were tested to find out the prejunctional mediator involved in the facilitation. The …

Harninkontinenz beim Mann – Ursachen, Diagnostik und Therapie

2017

Zusammenfassung. Dieser Übersichtsartikel beleuchtet den aktuellen Kenntnisstand zur Ätiologie, Diagnostik und Therapie der Harninkontinenz des Mannes. In der Ätiologie der Harninkontinenz beim Mann spielt die radikale Prostatektomie eine herausragende Rolle, aber auch das benigne Prostatasyndrom, neurologische Erkrankungen oder metabolische Störungen können zu einer Harninkontinenz beim Mann führen. In der Diagnostik ist neben der Basisdiagnostik eine qualifizierte urodynamische Beurteilung unabdingbar, um die zugrunde liegenden pathophysiologischen Mechanismen aufzudecken und Chancen und Risiken der verfügbaren Therapie- bzw. Operationstechniken abschätzen zu können. Die Primärtherapie d…

Die bipolare Stimulation kann die Erfolgsrate des Peripheren Nervenevaluationstests der sakralen Neuromodulation verbessern

2017

Zusammenfassung Fragestellung Die vorliegende Studie vergleicht die unipolare und die bipolare Stimulationstechnik während des Peripheren Nervenevaluationstestes der Sakralen Neuromodulation in einer Kohorte von 100 Patienten mit nicht-neurogenen und neurogenen Harntraktfunktionsstörungen und überprüft die Hypothese, dass die bipolare Technik der unipolaren bezogen auf die Testeffektivität überlegen ist. Material und Methoden In diese Fall-Kontroll-Studie wurden 43 Patienten mit biopolarer und 57 Patienten mit unipolarer Stimulation eingeschlossen. Für die bipolare Stimulation wurden vier Elektroden an S3 und S4 beidseits platziert und die Elektroden von S3 und S4 jeder Seite elektrisch ver…

Beeinflussung der Pharmakodynamik von Rocuronium durch Cimetidin

1996

Nach Gabe von Cimetidin kann die Wirkungszeit nichtdepolarisierender Muskelrelaxanzien verlangert sein. Wir untersuchten diesen Zusammenhang fur Rocuronium nach einer Einzeldosis von 400 mg Cimetidin intravenos im Vergleich mit einer Kontrollgruppe. Die Antwort des M. adductor pollicis nach Stimulation des N. ulnaris wurde elektromyographisch registriert. Die Anschlags- und Erholungszeiten sind in beiden Gruppen vergleichbar. Der fehlende Einflus von Cimetidin auf die neuromuskulare Blockade von Rocuronium konnte darauf hindeuten, das die Elimination von Rocuronium nicht nur in der Leber stattfindet. Eine mogliche direkte Beeinflussung der neuromuskularen Endplatte durch Cimetidin, wie sie …

Laparoscopic management of quadruplet heterotopic pregnancy after ovarian stimulation cycle

2016

Introduction. We report a rare case of a heterotopic abdominal pregnancy with three intrauterine pregnancy, one with a viable fetus, treated successfully by laparoscopy. Methods. A 40-year-old patient with primary sterility, who un- derwent pharmacological ovulation induction, presented abdominal pain in the right iliac region. A trans-vaginal ultrasound showed an image suggestive of ectopic gestation near the right ovary, associated with three intrauterine gestational sacs with only one viable fetus. Basing on this observation, we performed an operative laparoscopy that confirmed the presence of a right ectopic abdominal pregnancy. Since the right ampullar tubal was ruptured and bleeding, …
