Palmitoyl-CoA (Pal-CoA) lowered the respiratory control ratio (RCR), and induced mitochondrial membrane permeability transition (MPT) and cytochrome c (Cyt. c) release from isolated rat liver mitochondria. L-Carnitine suppressed the Pal-CoA-induced dysfunction, MPT, and Cyt. c release of isolated mitochondria. This suppression was inhibited by(More)
The effect of loxoprofen-Na, a novel non-steroidal anti-inflammatory drug with a prodrug property, on prostaglandin (PG) levels in the inflammatory tissue was investigated with a carrageenin-induced pleurisy model in rats. The intrapleural injection of carrageenin caused a marked increase in the levels of PGE2 and 6-keto-PGF1 alpha in the pleural exudate up(More)
The susceptibility of haemopoietic stem cell deficient W/Wv mice to infection with Plasmodium berghei was examined. The mean survival time of W/Wv mice after the infection was shorter than that of the +/+ mice. Splenomegaly, a characteristic pathological change of the host after infection with malaria parasites was not observed in W/Wv mice. When(More)
We examined the effect of adherent cells from bone marrow or spleen of mice infected with Plasmodium berghei on dyserythropoiesis. Significant reduction in number of erythroid progenitors (erythroid colony-forming units: CFU-E and erythroid burst-forming units: BFU-E) was observed in bone marrow as early as 1 day after P. berghei infection. When adherent(More)
The kinetic changes of hemopoietic stem cells in bone marrow and spleen were compared between lethal Plasmodium berghei- and non-lethal P. yoelii 17x-infected mice. P. yoelii 17x-infected mice showed more severe splenomegaly than those infected with P. berghei. P. yoelii 17x-infected mice also showed a greater degree of sustained increase in number of(More)
Infection of mice with Plasmodium berghei engendered a temporary appearance of granulocyte-macrophage colony-stimulating factor (GM-CSF) in the serum. The peak of GM-CSF levels was detected at day 2 post-infection, and then gradually decreased. On the other hand, the number of committed stem cells for granulocytes and macrophages (CFU-GM) in bone marrow(More)
Extramedullary hemopoiesis, recognized as hemopoietic foci, increased in the livers of Toxocara canis-infected mice. At the peak of the response (day-13 after infection), the majority of hepatic hemopoietic foci were of the eosinophil lineage. Hepatic nonparenchymal cells prepared from T. canis-infected mice on day 13 contained large numbers of hemopoietic(More)
The administration of lead acetate increased acid phosphatase activities in the rat brain and four regions (cerebral cortex, diencephalon plus mesencephalon, pons plus medulla, and cerebellum) of the guinea pig brain, whereas ascorbic acid content in the brain of these animals remained unchanged following lead administration. Acid phosphatase activity also(More)
