proximal renal tubular cells, human renal cortical cells and human renal cortical tissues, determined using the MTT assaying technique, the [3H]-thymidine uptake and glucose consumption tests, was found to be quite less than those of cisplatin. Based on these results, this novel platinum(II) coordination complex appears to be better for improving antitumor activities with low nephrotoxicity and is a valuable lead in the development of new clinically available anticancer chemotherapeutic agents.

acid (GCDC; 0∼400μM) for 3 hours. In electron microscopic examination and agarose gel electrophoresis, low concentration of GCDC treatment mainly induced apoptotic feature. Whereas 400μM GCDC treated cells demonstrated both apoptosis and necrosis. Lipid peroxidation was increased dose- dependently in GCDC treated hepatocyte. And this was also accompanied by decreased glutathione. Therefore, oxygen free radical damage may play a partial role in GCDC-induced hepatic cell death.

contraction in dose-dependent manner, but phospholipase C activity was not affected by the Ca2⁢ store emptying-induced contraction. The contraction was inhibited by voltage-dependent Ca2⁢ channel antagonists dose dependently, but not by TMB-8 (intracellular Ca2⁢ release blocker). Both PKC inhibitors (H-7 and staurosporine) and tyrosine kinase inhibitors (genistein and methyl 2,5-dihydroxycinnamic acid) significantly inhibited the contraction, but calmodulin antagonists (W-7 and...

Chronic exposure to cadmium (Cd) results in an inhibition of protein endocytosis in the renal proximal tubule, leading to proteinuria. In order to gain insight into the mechanism by which Cd impairs the protein endocytosis, we investigated the effect of Cd on the acidification of renal cortical endocytotic vesicles (endosomes). The endosomal acidification was assessed by measuring the pH gradient-dependent fluorescence change, using acridine orange or FITC-dextran as a probe. In renal endosomes...

Transition metal ions including Se2⁢, Cd2⁢, Hg2⁢ or Mn2⁢ have been thought to disturb the bone metabolism directly. However, the mechanism for the bone lesion is unknown. In this study, we demonstrated that MC3T3E1 osteoblasts, exposed to various transition metal ions; selenium, cadmium, mercury or manganese, generated massive amounts of reactive oxygen species (ROS). The released ROS were completely quenched by free radical scavengers-N-acetyl cysteine (NAC), reduced...

Although nociceptive informations are thought to be processed via different neural mechanisms depending on the types of stimuli, sufficient data have not been accumulated yet. We performed a series of experiments to elucidate the possible neural mechanisms as to chemical stimuli such as formalin, capsaicin and ATP. Single unit activity of wide dynamic range (WDR) neurons and high threshold cells were recorded extracellularly from the lumbosacral enlargement of cat spinal cord before and after...

dose dependent manner, and the concentration-dependence curve was well described by the Hill equation with KD value of 19.1μM. The blocking effect of capsaicin was reversible. Capsaicin (10 μM) shifted the steady- state inactivation curve in the hyperpolarizing direction by about 15 mV and increased the rate of inactivation. The voltage dependence of activation was not affected by capsaicin. These multiple effects of capsaicin may suggest that capsaicin bind to the region of K⁢ channel,...

carbonyl formation induced by cyclosporine plus ascorbate. Cyclosporine (100 μM) and 50 μM Fe2⁢ (or 100 μM ascorbate) synergistically stimulated degradation of 2-α deoxyribose. Cyclosporine (1 to 100 μM) reduced ferric ion in a dose dependent manner, which is much less than ascorbate action. Addition of Fe2⁢ caused a change in absorbance spectrum of cyclosporine in 230∼350 nm of wavelengths. The results show that cyclosporine plus iron (or ascorbate) exerts an enhanced damaging...

in very low frequency (VLF, 0∼0.05 Hz), low frequency (LF, 0.05∼0.15 Hz) and high frequency (HF, 0.15∼0.50 Hz) bands, normalized powers (LFn and HFn) and LF/HF ratio were obtained. After ethanol ingestion, F showed higher heart rate than NF. PS increased LFn (⁢22.9⁑3.6 in NF, ⁢12.8⁑4.7 in F, in normalized units) and LF/HF (⁢3.10⁑0.57 in NF, ⁢3.00⁑1.08 in F) and decreased HFn powers.
