Inhibition of Voltage-Dependent Ca2+ Influx by Extracellular ATP in Salivary Cells of the Leech Haementeria Ghilianii

Autor: T. Munsch, J. W. Deitmer, W. A. Wuttke

Publikováno v: Journal of Experimental Biology. 199:1335-1341

The effects of extracellular ATP on intracellular free Ca2+ concentration ([Ca2+]i) and depolarization-induced elevations of [Ca2+]i were investigated in salivary cells of the leech Haementeria ghilianii using the fluorescent Ca2+ indicator Fura-2. S

Independent mechanisms of potassium clearance by astrocytes in gliotic tissue

Autor: W, Walz, W A, Wuttke

Publikováno v: Journal of neuroscience research. 56(6)

The "glial impairment hypothesis" states that astrocytes which change from normal into the reactive type lose their ability to clear extracellular K+, which in turn leads to hyperexcitability in the gliotic tissue. As this hypothesis was never proven

Rapid co-transport of sodium and chloride ions in giant salivary gland cells of the leech Haementeria ghilianii

Autor: M S Berry, W A Wuttke

Publikováno v: The Journal of physiology. 427

1. Double-barrelled Cl(-)-selective microelectrodes were used to measure the apparent intracellular Cl- activity (aiCl) and membrane potential (Em) of leech salivary gland cells. In standard physiological solution buffered with HEPES (10 mM), intrace

[Primary lymphoblastic lymphoma of the thyroid]

Autor: W, Zahradka, W D, Wuttke, F, Gehrandt

Publikováno v: Zeitschrift fur die gesamte innere Medizin und ihre Grenzgebiete. 45(2)

Report is given on a 78-years-old woman with a primary lymphoblastic lymphoma of the thyroid gland. The lymphoma had invaded the trachea. An extrathyroid manifestation of the lymphoma was not found. There was no Hashimoto's thyroiditis. The patient d

Evidence for the uptake of neuronally derived choline by glial cells in the leech central nervous system

Autor: V W Pentreath, W A Wuttke

1. With ion-sensitive microelectrodes based on the Corning exchanger 477317, the accumulation of an unidentified interfering substance was monitored in leech neuropile glial cells but not in neurons after a 10-fold increase in extracellular K+ concen
