This study was performed to examine 1) Whether hypothermic cardiac arrest produces myocardial HSP72 expression; 2) And if, whether it serves to protect the heart against the subsequent hypothermic arrest. In the present study, neonatal rats were placed in an icebath to induce hypothermia. To determine whether hypothermic cardiac arrest produces myocardial HSP72, experimental animals were subjected to 10-min hypothermic insult before the extraction of the heart. The intervals between the insult...

This investigation is to determine whether the surface complexation of iron influence acute pulmonary responses induced by silica. For this study, three varieties of cation complexed silica were used: silica-H⁢, -Zn2⁢, and -Fe3⁢, since the first two are not active in the transport of electrons and generate little free radicals relative to the dust with the surface iron. Rats (270 to 280 g) were intratracheally (IT) instilled with saline, silica-H⁢, -Zn2⁢, or...

In the present study, the underlying mechanisms for diabetic functional derangement and insulin effect on diabetic cardiomyopathy were investigated with respect to sarcoplasmic reticulum (SR) Ca2⁢-ATPase and phospholamban at the transcriptional and translational levels. The maximal Ca2⁢ uptake and the affinity of Ca2⁢-ATPase for Ca2⁢ were decreased in streptozotocin-induced diabetic rat cardiac SR, however, even minimal amount of insulin could reverse both parameters....

Interactions among dexamethasone, dehydroepiandrosterone (DHEA), lipopolysaccharide (LPS), and antimycin A on the glutamate uptake and the polyamine uptake were investigated in primary cultures of rat cerebral cortical astrocytes to examine the effects of dexamethasone and DHEA on the regulatory role of astrocytes in conditions of increased extracellular concentrations of glutamate or polyamines. 1. [3H]Glutamate uptake: LPS and antimycin A decreased Vmax, but both drugs had little effect on...

Apoptosis has been implicated in the pathophysiological mechanisms of various neurodegenerative diseases. In a variety of cell types, oxidative stress has been demonstrated to play an important role in the apoptotic cell death. However, the exact mechanism of oxidative stress-induced apoptosis in neuronal cells is not known. In this study, we induced oxidative stress in IMR-32 human neuroblastoma cells with tert- butylhydroperoxide (TBHP), which was confirmed by significantly reduced...

addition, N-acetyl-cysteine ameliorated histological damage. Allopurinol and ㄂- carotene attenuated cerulein-induced hyperamylasemia, but histologically there was no difference from control. These results indicate that oxygen free radicals play an important role in the initiation of experimental acute pancreatitis. N-acetyl-cysteine is an effective antioxidant that ameliorates the cerulein-induced acute pancreatitis, and the possible therapeutic application of antioxidants against acute...

This study investigated the role of nitric oxide on the oxidative damage in gastric mucosa of rats which received ischemia/reperfusion and its relation to mucus. Nitric oxide synthesis modulators such as L-arginine and NG-nitro-L-arginine methyl ester, and sodium nitroprusside, a nitric oxide donor, were injected intraperitoneally to the rats 30 min prior to ischemia/reperfusion which was induced by clamping the celiac artery and the superior mesenteric artery for 30 min and reperfusion for 1 h....

We have synthesized new platinum(II) analogs containing 1,2-diaminocyclohexane (dach) as a carrier ligand, 1,3-bis(diphenylphosphino) propane (DPPP) /1,2-bis(diphenylphosphino)ethane (DPPE) as a leaving group and nitrates to improve solubility. In the present study, the cytotoxicity of [Pt(trans-l-dach)(DPPP)]·2NO3 (KHPC-001) and [Pt(trans-l-dach)(DPPE)]·2NO3 (KHPC-002) was evaluated and compared on various P-388 cancer cell lines and porcine kidney cell line (LLC-PK1). The new platinum...

The role of nitric oxide (NO) in the hemorrhagic hypotension was examined using a NO synthase inhibitor, Nω-nitro-L-arginine methyl ester (L-NAME), in conscious rats. The rats were bled at a constant rate (2 ml/kg/min) through a femoral arterial catheter until the mean arterial pressure (MAP) was reduced by 50 mmHg. We studied the responses to hemorrhage under normal condition (Control) and after the pretreatment with 3 doses of L-NAME (1.6, 8, 40 mg/kg i.v. of NOX1.6, NOX8, and NOX40,...

Stimulated alveolar macrophages and neutrophils produce nitric oxide, a free radical by an inducible nitric oxide synthase(iNOS), which reacts with superoxide anion to form peroxynitrite, a more highly reactive toxic species. The objectives of the present study were to evaluate acute inflammatory lung injury and to determine iNOS mRNA induction and nitric oxide production by rat broncho-alveolar lavage cells following intratracheal treatment of silica. After 4 h exposure to silica, differential...
