Diabetic polyneuropathy is a serious complication in patients with diabetes mellitus. In addition to the maintenance of a sufficient metabolic control, alpha-lipoic acid (ALA) (Thioctacid, Asta Medica) is known to have beneficial effects on diabetic polyneuropathy although the exact mechanism by which ALA exerts its effect is unknown. In order to study the(More)
OBJECTIVE We examined the effect of lipoic acid (LA), a cofactor of the pyruvate dehydrogenase complex (PDH), on insulin sensitivity (SI) and glucose effectiveness (SG) and on serum lactate and pyruvate levels after oral glucose tolerance tests (OGTTs) and modified frequently sampled intravenous glucose tolerance tests (FSIGTTs) in lean (n = 10) and obese(More)
Patients with diabetic polyneuropathy are known to have an impaired neurovascular reflex arc compared to healthy controls. This is seen in a delayed decrease in microcirculation of the ipsilateral hand after cooling of the contralateral hand. The aim of this pilot study was to investigate whether intravenous alpha-lipoic acid (ALA) (Thioctacid, Asta Medica)(More)
We investigated microcirculatory changes in sodium taurocholate (ST)-induced pancreatitis. Groups of rats received as tracer either fluorescein isothiocyanate-dextran or acridine orange intravenously. The microcirculation of the exposed pancreas was observed by use of a video camera attached to an epi-illumination microscope. Vessel diameters and plaques of(More)
The sensitive detection of circulating tumour cells in patients with differentiated thyroid cancer may precede the detection of relapse by other diagnostic studies--such as serum thyroglobulin-and thus may have important therapeutic and prognostic implications. We performed reverse transcription-polymerase chain reaction (RT-PCR) on blood samples from(More)
BACKGROUND Cholestasis is a complication that occurs during the rejection of liver transplants. The aim of this study was to investigate the association of activated Kupffer cells (KCs) and Na+,K+-ATPase activity for taurocholate cotransport and bile canalicular (BC) Mg++-ATPase activity for hepatobiliary excretion in rat liver allograft. METHODS(More)
In the model of the perfused rat liver, we investigated the alterations of sinusoidal cells in the pathogenesis of liver injury caused by hypoxia and reperfusion. In sinusoidal endothelial cells, the activity of xanthine oxidase (XOX), a cytoplasmic marker enzyme, was located cytochemically and determined biochemically. Kupffer cells, identified by their(More)
The effect of B2 receptor bradykinin antagonist icatibant on postcapillary leukostasis, microcirculatory stasis, and tissue necrosis was studied in acute pancreatitis. In rats, pancreatitis was induced by intraductal injection of sodium taurocholate (ST), intravenous caerulein and intraductal infusion of glucodeoxycholic acid (GDOC), or intravenous(More)
OBJECTIVE/METHODS In order to investigate whether selective hypertriglyceridemia impairs endothelium-dependent vasodilatation in the rat hindlimb, rats were selectively bred to establish two strains, one with a pronounced hypertriglyceridemia (HT) and the other with normal plasma levels of triglycerides (LT). RESULTS Carotid arteries and aortae removed(More)
Using an in vivo microscopy technique, we studied the microcirculatory changes in sodium taurocholate-induced pancreatitis in rats. With a computerized image analyzer system, blood flow, vascular permeability changes, and capillary densities were measured. Intraductal infusion of 0.4 ml saline had only minor effects on the microcirculation. Various(More)
