Wogonin, a natural flavonoid, is one of the bioactive compounds of the medicinal herb Eucommia ulmoides OLIV. widely used in southeastern Asia for treating hypertension. However, the molecular mechanisms for the therapeutic benefits remain largely unclear. The present study investigated the vasodilatory effect of wogonin and its possible mechanisms. The flavonoid (0.1-100 µM) caused concentrati...

Vol. 36 No. 5 • May 2011 • P&T® 241 of breath, and his physician had prescribed an IV dose of furosemide (Lasix, Sanofi-Aventis). The pharmacy was closed, so a nurse entered the secured section of the pharmacy to obtain the drug. She mistakenly selected a vial of KCl instead of furosemide; both drugs were kept on nearby shelves just above the floor. She took the vial to the unit, withdrew the m...

The potential difference across the protoplasm of impaled cells of two American species of Halicystis is compared. The mean value for H. Osterhoutii is 68.4 mv.; that for H. ovalis is 79.7 mv., the sea water being positive to the sap in both. The higher potential of H. ovalis is apparently due to the higher concentration of KCl (0.3 M) in its vacuolar sap. When the KCl content of H. Osterhoutii...

Ion-surface interactions are of high practical importance in a wide range of technological, environmental and biological problems. In particular, they ultimately control the electric double layer structure, hence the interaction between particles in aqueous solutions. Despite numerous achievements, progress in their understanding is still limited by the lack of experimental determination of the...

In most phosphorus (P) sorption studies, P is added as an inorganic salt to a predefined background solution such as calcium chloride (CaCl2) or potassium chloride (KCl); however, in many regions, the application of P to agricultural fields is in the form of animal manure. The purpose of this study, therefore, was to compare the sorption behavior of dissolved reactive P (DRP) in monopotassium p...

The effect of temperature upon the bioelectric potential across the protoplasm of impaled Valonia cells is described. Over the ordinary tolerated range, the P.D. is lowest around 25 degrees C., rising both toward 15 degrees and 35 degrees . The time curves are characteristic also. The magnitude of the temperature effect can be controlled by changing the KCl content of the sea water (normally 0....

Microcyst formation can be induced by increasing the osmotic pressure of the surrounding medium. Certain ions such as K(+), Ca(++), or Mg(++) may be needed in the encystment process, and the presence of divalent cations increases the rate of encystment and cyst maturation. Chloride of potassium is optimal for encystment, but other anions of potassium are either less effective or toxic. The opti...

Priming of seeds increases uniformly germination rate in cultivated and wild species as well, it also shortens emergence time. Beautiful vavilovia, Vavilovia formasa (Stev.) Al. Fed. is a relict endangered legume crop which the closest relatives genus Pisum L. In beautiful seed priming has ignored due to insufficient production plant. present report, three including hydro-priming, glycerol (%1)...

The growth of ultra-thin KCl films on the Si(111)7 × 7 reconstructed surface has been investigated as a function of KCl coverage and substrate temperature. The structure and morphology of the films were characterized by means of scanning tunneling microscopy (STM) under ultra-high vacuum (UHV) conditions. Detailed analysis of the atomically resolved STM images of islands grown at room and high ...

In this paper, an experimental setup was established to study the influence of potassium chloride (KCL) solution as ground electrode on nitrogen oxides (NOx) removal efficiency in non-thermal plasma (NTP) generated by dielectric barrier discharging (DBD) reactor. The results show that KCL has better stability and higher discharge intensity it is a promising approach improve NOx efficiency. spec...
