Vergleichende Messung der Thrombocytenaggregation: Extinktion und Siebungsdruck von plättchenreichem HumanplasmaPflügers Archiv - Tập 303 - Trang 274-286 - 1968
B. Krankenhagen, H. Hirsch, H. Mann
Die in vitro durch ADP induzierte reversible und irreversible Thrombocytenaggregation wurde als Extinktionsänderung nach der Methode vonBorn u.O'Brien und als Siebungsdruck nach der Methode vonSwank gemessen. Zunehmende Aggregation führt im allgemeinen zur einer Abnahme der Extinktion und zu einer Erhöhung des Siebungsdrucks, abnehmende Aggregation zu einer Zunahme der Extinktion und einer Abnahme...... hiện toàn bộ
Oral contraceptives alter sleep and raise body temperature in young womenPflügers Archiv - Tập 442 - Trang 729-737 - 2001

Female reproductive steroids, oestrogen and progesterone, not only affect reproductive function, but also thermoregulation and sleep. Chronic administration of synthetic steroids, as occurs in women taking oral contraceptives, may affect these regulatory systems differently from endogenous oestrogen and progesterone. We therefore investigated body temperature and sleep in ten young women taking o...... hiện toàn bộ
Ca2+ channel activities in the limb bud of early embryonic chickPflügers Archiv - Tập 429 - Trang 876-878 - 1995
Yukiko Yoshimoto, Masayuki Yamashita
Ca2+ channel activities were recorded in the limb bud of embryonic day 4 chick with Ca2+ sensitive fluorescence (Fura-2) measurements and patch clamp techniques. Rises in intracellular Ca2+ concentrations were evoked by depolarization with the application of 100 mM K+ and this Ca2+ response was abolished by removing extracellular Ca2+. The Ca2+ response was blocked by 10 μM nifedipine and enhanced...... hiện toàn bộ

An apical membrane Na+/H+ exchanger isoform, NHE-3, is present in the rat epididymal epitheliumPflügers Archiv - Tập 442 - Trang 230-236 - 2001

An acidic milieu is required for sperm maturation and for keeping sperm quiescent during storage in the cauda epididymidis. Previous studies have implicated a Na+/H+ exchanger (NHE) in epididymal acidification together with carbonic anhydrase (CA) and vacuolar proton adenosine triphosphatase (H+-ATPase). The present studies were undertaken to discover whether the NHE isoform involved is NHE-3, wh...... hiện toàn bộ
Aldosterone does not stimulate the Na:K pump in isolated turtle colonPflügers Archiv - Tập 403 - Trang 236-239 - 1985
Dan R. Halm, David C. Dawson
The study of the mechanisms by which mineralocorticoids stimulate sodium absorption across distal epithelia has focused on three possible sites of action: apical sodium permeability, the basolateral Na∶K pump, and the production of high-energy substrates. Recently we developed a method for direct measurement of the current generated by the basolateral Na∶K pump of the turtle colon [15]. In the pre...... hiện toàn bộ
