Ca2+-activated Cl- (ClCa) channels were characterized biophysically and pharmacologically in a mouse kidney inner medullary collecting duct cell line, IMCD-K2. Whole cell recording was performed with symmetrical N-methyl-d-glucamine chloride (NMDG)-Cl in the intracellular and extracellular solutions, and the intracellular Ca2+ concentration ([Ca2+]i) was adjusted with Ca2+-EGTA buffers. The amp...
Freshly dispersed interstitial cells from the rabbit urethra were studied by using the perforated-patch technique. When cells were voltage clamped at -60 mV and exposed to 10 microM norepinephrine (NE) at 80-s intervals, either large single inward currents or a series of oscillatory inward currents of diminishing amplitude were evoked. These currents were blocked by either phentolamine (1 micro...
We have investigated the volume-activated transport of organic solutes in flounder erythrocytes. Osmotic swelling of cells suspended in a Na(+)-free medium led to increased membrane transport of taurine, glucose, and uridine. For each compound there was a significant lag period (1-2 min at 10 degrees C) between cell swelling and activation of the flux. The volume-activated fluxes of each of the...
Muscarinic receptor mediated membrane currents and contractions were studied in isolated canine colon circular smooth muscle cells. Carbachol (10(-5) M) evoked a slow transient inward current that was superimposed by a transient outward current at holding potentials greater than -50 mV. Carbachol contracted the cells by 70 +/- 2%. The effects of carbachol were blocked by atropine (10(-6) M), te...
We have previously demonstrated the presence of a cyclic GMP (cGMP)-dependent calcium-activated inward current in vascular smooth-muscle cells, and suggested this to be of importance in synchronizing smooth-muscle contraction. Here we demonstrate the characteristics of this current. Using conventional patch-clamp technique, whole-cell currents were evoked in freshly isolated smooth-muscle cells...
Flufenamic acid (FFA) is a nonsteroidal anti-inflammatory drug (NSAID). It has anti-inflammatory and antipyretic properties. In addition, it modulates multiple channel activities. The mechanisms underlying the pharmacological actions of FFA are presently unclear. Given that AMP-activated protein kinase (AMPK) has both anti-inflammatory and channel-regulating functions, we examined whether FFA i...
قارچ ها به عنوان یکی از مهمترین عوامل بیماریزای گیاهی، منبع اصلی از متابولیت های ثانویه بیواکتیو هستند، و از اهمیت قابل توجهی در فعل و انفعالات زیست محیطی برخوردار می باشند از جمله متابولیت ها می توان آنتی بیوتیک ها، توکسین ها و آنزیم ها را نام برد. در این پژوهش شناسایی متابولیت های ثانویه تولید شده در 21 گونه قارچی با کمک gc – ms انجام گردید. نتایج حاصل از بررسی قابلیت ضد باکتریایی، ضد قارچی، ...
