Dynamics of BCR-ABL mRNA expression in first-line therapy of chronic myelogenous leukemia patients with imatinib or interferon alpha/ara-C.
We sought to determine dynamics of BCR-ABL mRNA expression levels in 139 patients with chronic myelogenous leukemia (CML) in early chronic phase, randomized to receive imatinib (n=69) or interferon (IFN)/Ara-C (n=70). The response was sequentially monitored by cytogenetics from bone marrow metaphases (n=803) and qualitative and quantitative RT-PCR from peripheral blood samples (n=1117). Complete cytogenetic response (CCR) was achieved in 60 (imatinib, 87%) vs 10 patients (IFN/Ara-C, 14%) after a median observation time of 24 months. Within the first year after CCR, best median ratio BCR-ABL/ABL was 0.087%, (imatinib, n=48) vs 0.27% (IFN/Ara-C, n=9, P=0.025). BCR-ABL was undetectable in 25 c…
Expression of fibronectin splice variants and oncofetal glycosylated fibronectin in the synovial membranes of patients with rheumatoid arthritis and osteoarthritis
The aim of this study was to define and compare the expression of fibronectin (Fn) isoforms in synovial tissue of patients with rheumatoid arthritis (RA) and osteoarthritis (OA).Using monoclonal antibodies specific for total Fn, extra domain (ED)-A Fn, ED-B Fn, and oncofetal glycosylated Fn, we studied the expression of the Fn isoforms in synovium. Furthermore, in situ hybridization for the detection of ED-B Fn mRNA including a double labeling technique for the detection of cell type was applied.Strong expression of total Fn, ED-A Fn, oncofetal glycosylated Fn and, to a lesser extent, ED-B Fn could be demonstrated in the synovial lining layer in both RA and OA. Stromal and vessel expression…
Sekretion, Verteilung und Abbau von Aldosteron bei verschiedenen Hochdruckformen
Bei 11 normotensiven Kontrollpersonen, 11 Patienten mit milder essentieller Hypertonie, 5 Patienten mit fortgeschrittener essentieller Hypertonie, 5 Patienten mit primarem Aldosteronismus und 13 Patienten mit Hypertonie in Verbindung mit Nierenarterienstenose wurde die Sekretionsrate (SR) und die metabolische Clearancerate (MCR) von Aldosteron bestimmt. Folgende Determinanten der metabolischen Clearancerate wurden zusammen mit MCR ausA,B, α, undβ, den Konstanten der3H-Aldosteronplasmakonzentration-Zeit-Funktion nach i.v. Injektion von3H-Aldosteron, berechnet: Die GeschwindigkeitskonstantenK 1 undK 2 fur die Verteilung und den Abbau des Aldosterons, die virtuellen VerteilungsvoluminaV 1 undV…
