We recently reported a cardioselective and cumulative oxidation of cardiac mitochondrial DNA (mtDNA) following subchronic administration of doxorubicin to rats. The mtDNA adducts persist for up to 5 weeks after cessation of doxorubicin treatment. Since the evidence suggests that this persistence of mtDNA adducts cannot be attributed to a lack of repair and(More)
Interference with mitochondrial calcium regulation is proposed to be a primary causative event in the mechanism of doxorubicin-induced cardiotoxicity. We previously reported disruption of mitochondrial calcium homeostasis after chronic doxorubicin administration (Solen et al. Toxicol. Appl. Pharmacol, 129: 214-222, 1994). The present study was designed to(More)
In previous studies we showed that doxorubicin (DOX) interferes with mitochondrial calcium homeostasis and that cardiac mitochondria from DOX-treated rats express a dose-dependent, cumulative, and irreversible decrease in calcium-loading capacity. Associated with this is an increased sensitivity to calcium-induced cell killing of cardiac myocytes from(More)
Peroxisome proliferators are a group of structurally diverse chemicals that cause the proliferation of peroxisomes in rodents. The purpose of this investigation was to test the hypothesis that the shared effect of these compounds on peroxisome proliferation is mediated through a common inhibitory effect on mitochondrial bioenergetics. Freshly isolated rat(More)
The aim of this study was to investigate the effect of Bu-Shen-An-Tai recipe (BSATR) and its two components (Bushen recipe, and Huoxue recipe) on endometrial morphology during peri-implantation in superovulated mice. Mice were randomly divided into five groups, including the normal (N), model (M), Bushen (BS), Huoxue (HX) and Bu-Shen-An-Tai (BH) groups. The(More)
To observe the pharmacokinetic and tissue-distribution characters of 5-flourouracil magnetic albumin deuto-microsphere (5-Fu-MAD) in normal and tumor-bearing mice, HPLC method for the determination of 5-Fu in plasma and tissues was established and applied to determine 5-Fu in mouse plasma and tissue samples. A Flame atomic absorption spectrometer was used(More)
The aim of this study was to investigate the mechanism of bromodichloromethane (BDCM) - induced cell proliferation in different tissues of male F344 rats. Rats were administered at doses of 0 and 100mg/kg/day BDCM dissolved in corn oil by gavage for 5 days/week for 1, 4, 8 and 12 weeks. Then the colon, kidney and liver were collected. No histologic lesions(More)
Brain-derived neurotrophic factor (BDNF) was recently identified as a factor produced by multiple myeloma (MM) cells, which may contribute to bone resorption and disease progression in MM, though the molecular mechanism of this process is not well understood. The purpose of this study was to test the effect of BDNF on bone disease and growth of MM cells(More)
AIM To observe the effect of phenolic alkaloids of Menispermum dauricum (PAMD) on the hemodynamics, coronary circulation and oxygen metabolism of the myocardium in anesthetized dogs. METHODS In this study, the changes of LVSP, LVEDP and +/- dp/dtmax, the flow of coronary artery and myocardial energy metabolism were measured in anesthetized dog with PAMD(More)
