The objective of the present study in 60 patients with chronic tinnitus aurium was to confirm efficacy oral treatment 2 x 80 mg Ginkgo special extract EGb 761 per day subsequent 10-day infusion treatment.Patients underwent 10 days in-patient 200 mg/day 761, after which they were randomized double-blind, out-patient either or placebo, given over a scheduled period 12 weeks. primary outcome measure change volume more severely affected ear during treatment.Fifty-two (89.7%) completed treatment;...
After obliteration of endolymphatic sac and duct, no significant alteration in d.c. potential, K+ activity or protein content during the development hydrops could be observed. The K was only one-ninth that cochlear part endolymph. injection Thoro-trast into sac, aggregated particles were found endolymph 2 days later. Etha-erynic acid (60 mg/kg) caused a decrease endolymph, but an increase sac. Intercellular edema observed both stria vascularis by light electronmicroscopy after ethacrynic...
The protein content and the d.c. potential of endolymph differs in various parts endolymphatic space (cochlea, utricle, semicircular canals sac) as also does ion composition (chloride, potassium, sodium). 12 months after obliteration sac duct guinea pigs falls, whereas. sodium activity increases. hydrops is not caused by an increased colloid osmotic pressure. water-binding capacity cochlear correlated with Na+ activity.
<b>Ziel:</b> Untersucht wird, inwiefern sich Konsummuster von neuen psychoaktiven Substanzen (NPS) in den letzten Jahren verändert haben. <b>Methodik:</b> Innerhalb rund 2 ½ wurden Online-Befragungen mit NPS-Erfahrenen durchgeführt; die Stichproben ähneln zentralen Aspekten stark. Die quantitativen Daten mithilfe üblicher statistischer Prozeduren analysiert. <b>Ergebnisse:</b> Aktueller Konsum NPS hat der zweiten Erhebung abgenommen. Der Gebrauch NPS-Produkten ohne genaue Deklaration hin zu...
Within the pancreas, Keratin 19 (KRT19) labels ductal lineage and is a determinant of pancreatic adenocarcinoma (PDAC). To investigate KRT19 expression dynamics, we developed human pluripotent stem cell (PSC)-based KRT19-mCherry reporter system in different genetic backgrounds to monitor from its endogenous gene locus. A differentiation protocol generate mature duct-like organoids was applied. While KRT19/mCherry became evident at early endoderm stage, mCherry signal present nearly all cells...
Ca++ activity and DC potential were measured in vivo the endolymphatic sac (ES) of guinea pigs by means double-barrelled ion-sensitive microelectrodes. We found a positive 14 mV 4.7 X 10(-4) M. Anoxia induced decrease an increase activity; however, no negative was during permanent anoxia. The agreement with value calculated Nernst equation, assuming potential. On basis these data, it suggested that ES is electrochemical equilibrium surrounding fluid active transport necessary pigs.
The mucosa of the middle ear is not only supplied with oxygen from blood but also air space ear. Under physiological conditions, perilymph partially tympanic cavity. When Po 2 in falls below 57 mm Hg, a net diffusion flux to induces loss inner A negative pressure 25 Hg generated ear, causes transudate. Subsequently, slight disturbances microcirculation should occur mucosal membrane. More pronounced pressures lead very distinct and local supply.
