Background: Palliative care team (PCT) is a common type of palliative care services. However, distress in cancer patients may be underestimated by hospital staff. Reasons for PCT consultation may be inconsistent with patients' actual needs.

The recommended dosage for patients with creatinine clearance(Ccr)of less than 60mL/min was established on the basis of an area under the curve analysis, but is doubted because it was calculated without performing a clinical trial. Creatinine secretion from the renal tubule affects Ccr; therefore, using Ccr as the basis for dosage adjustment may be inappropriate since this can cause an overestimation of the glomerular filtration rate(GFR).

The results for the changes in [Ca(2+)]( i ) by 5-HT were as follows, (1) The 5-HT-induced Ca(2+) response was inhibited by 3 x 10(-9) M tropisetron (a 5-HT(3) receptor blocker), but not by other types of 5-HT receptor blockers; (2) The 5-HT-induced Ca(2+) response was mainly inhibited by calciseptine (a L-type Ca(2+) blocker), but not by other types of Ca(2+) channel blockers or 10(-7) M TTX (a voltage-sensitive Na(+) channel blocker); (3) When the extracellular Na(+) was removed by exchange with choline chloride or N-methyl-D-glucamine, the 5-HT-induced Ca(2+) response was extremely inhibited. The results for the 5-HT-induced Na(+) current by the whole cell patch-clamp technique were as follows, (1) The 5-HT-induced Na(+) current in differentiated cells was significantly larger than that in undifferentiated cells; (2) The ED(50) value for 5-HT-induced Na(+) current in undifferentiated and differentiated cells was almost the same, about 4 x 10(-6) M each other; (3) The 5-HT-induced Na(+) current was completely blocked by 3 x 10(-9) M tropisetron, but not by other 5-HT receptor antagonists and 10(-7) M TTX.

In this work, we investigated whether the enhancement of sodium current in differentiated neuroblastoma x glioma NG108-15 cells treated with dibutyryl cAMP is related to the expression of voltage-gated sodium channels. The results were as follows.

[Ca(2+)](i) was increased in a dose-dependent manner by bradykinin (BK) and serotonin (5-HT) in differentiated NG cells, and the response to BK and 5-HT was significantly greater than that in undifferentiated NG cells. The EC(50) value of BK was approximately 1.

Ratiometric Na+ imaging with a Na+-sensitive fluorescent dye SBFI (sodium-binding benzofuran isophthalate) revealed that the intracellular Na+ concentration ([Na+]i) was not affected by the application of high K+ (60 mM) solution to either control or differentiated cells. When cells were exposed to 50 microM veratridine (Vtd), an agonist of voltage-sensitive sodium channels (VSSCs), a significant increase in [Na+]i was observed in differentiated but not in undifferentiated cells.

The present study confirmed that the increasing effect of [Ca(2+)](i) by high-KCl application in single NG108-15 cells, differentiated with dibutyryl cAMP (Bt(2)cAMP), was significantly enhanced, compared to undifferentiated cells. The following observations were made at first: (1) The response to high-KCl application, in both undifferentiated and differentiated cells, was significantly inhibited by calciseptine (CaS), an L-type Ca(2+) channel blocker, but not by N-, P- and R-type Ca(2+) channel blockers.
