Exposure of rats to a reduced oxygen tension (6% O2, 94% N2) for 6 h increased the serum enzyme and the histological lesions induced by carbon tetrachloride (CCl4). Hypoxia did not enhance the hepatotoxic response to paracetamol, allyl alcohol, bromobenzene or thioacetamide. No correlation was found
The effects of an atypical barbiturate, valofan, and of a classical barbiturate, exobarbital, on the cerebral energy metabolism of rat have been evaluated under normoxic and hypobaric hypoxia conditions. In hypobaric hypoxia, the survival time was significantly increased by valofan 1.5 g/kg and
Kupffer cells play an important role in liver function and phagocytosis of foreign particles in the hepatic portal tract. Therefore, the purpose of this study was to investigate the influence of several hepatotoxic chemicals (allyl alcohol, ethylhexanol, and menadione) and hypoxia on phagocytic
OBJECTIVE
Retinal ischemia-associated ocular disorders are vision-threatening. The aim of the present study was to examine whether S-allyl l-cysteine (SAC) is able to protect against retina ischemia/reperfusion injury.
METHODS
In vivo, retinal ischemia in the rat was induced by raising intraocular
Hypoxia-inducible factor 1 (HIF-1) is a heterodimeric transcription factor composed of alpha and beta subunits. HIF-1 is critically involved in cellular responses to hypoxia, glycolysis, and angiogenesis. Here, we show that treatment of prostate cancer PC-3 and LNCaP cells with the benzoquinone
The aim of the present study was to investigate the role of myristicin (Myr; 1‑allyl‑5‑methoxy‑3,4‑methylenedioxybenzene), an active aromatic compound isolated from nutmeg, carrot, basil, cinnamon and parsley, in hypoxia‑induced apoptosis in rat dorsal root ganglion (DRG) neurons. It was observed
Spores of Bacillus megaterium were irradiated in suspension with 50 kVp X-rays under three reference conditions: in anoxia (i.e., 100 per cent N2); in anoxia with 2mM p-nitroacetophenone (PNAP), a concentration that shows the maximum amount of sensitization by this agent; and in air. The responses
The present study investigated the temporal relationship between neuronal nitric oxide synthase (nNOS) activity and expression and the development of neuronal damage occurring during anoxia and anoxia followed by reoxygenation. For this purpose, cerebellar granule cells were exposed to 2 hr of
Multifunctional silica nano-vehicles (SiO2@indol-IL) and magnetic nanoparticles (Fe3O4@indol-IL) were constructed through the Schiff bases condensation of indole-3-carboxaldehyde and 4-acetyl-N-allyl pyridinium chloride (ILs) with the amine groups of silica and magnetic nanoparticles. SiO2@indol-IL
S-(1,2-Dichlorovinyl)-L-cysteine (L-DCVC), a substrate for the renal cysteine conjugate beta-lyase, and other related chemicals were administered intravenously to pentobarbital-anesthetized dogs. Six pertinent findings emerged regarding their nephrotoxicity. (1) L-DCVC was acutely nephrotoxic in the
Vascular diseases like thrombosis, myocardial infarction, cerebral ischemia or chronic venous insufficiency affect a high proportion of the population. They are all associated with more or less pronounced ischemic conditions. We have previously shown that some venotropic drugs display an
The purpose of the present investigation was to study the effect of alpha-(+/-)-5-allyl-1-methyl-5-(1-methyl-2-pentinyl) barbituric acid (methohexital, Brevimytal sodium) on brain energy metabolism. The model of the isolated perfused rat brain was used. The high-energy phosphates, some substrates of
Treatment of rats with 2,4-dinitrophenol (DNP) markedly enhanced the release of enzymes into serum induced by carbon tetrachloride (CCl4). DNP also aggravated the hepatotoxic response to paracetamol but not that to allyl alcohol, bromobenzene and thioacetamide. DNP-induced hypoxia resulting in an
S-propargyl-cysteine (SPRC), also named as ZYZ-802, is a structural analog of S-allylcysteine (SAC), the most abundant constituent of aged garlic extract. SPRC becomes a derivative of the amino acid cysteine, which contains sulfur atom, by changing allyl group in SAC to propargyl group in SPRC.
