Lactate dehydrogenase (LDH) X has been isolated in crystalline form from mouse testes. Homogeneity of the protein preparation was established by disc gel electrophoresis, analytical ultracentrifugation, and immunochemical analyses. LDH-X is clearly distinct in amino acid composition from LDH-1 and LDH-5 with respect to numbers of residues of leucine, glycine, threonine, and methionine. When 6 t...

PURPOSE Interleukin-(IL)1beta expression is increased in the retina during a variety of diseases involving the death of retinal neurons and contributes to neurodegenerative processes through an unknown mechanism. This study was conducted to examine the effects of IL-1beta on the metabolism and viability of RGC-5 and R28 retinal neuronal cells. METHODS Cellular reductive capacity was evaluated...

Geranium koreanum (GK) is an indigenous Chinese herbal medicine widely used for the treatment of various inflammation and liver disorders. However, the exact mechanism of action of GK remains unknown. This study aimed to investigate the protective effect and related molecular mechanism of GK on NaAsO2-induced cytotoxicity in HepG2 cells and liver damage in mice. The cytoprotective role of GK wa...

Rhopalurus junceus scorpion venom has been identified as a natural extract with anticancer potential. Interestingly, this scorpion venom does not cause adverse symptoms in humans. However, there is scarce information about its composition and enzymatic activity. In this work, we determined the electrophoretic profile of the venom, the gelatinase and caseinolytic activity, and the phospholipase ...

The influence of pulsed electric field (PEF) (0.5-2 kV/cm) treatment of wheatgrass (Triticum aestivum L.) seeds, with different water contents, on antioxidant metabolism in the resultant seedlings was investigated. Imbibing seeds to a water content of 45% or greater prior to PEF treatment increased the glutathione level and activities of superoxide dismutase, catalase, glutathione reductase, gl...

UNLABELLED The viability, cytolysis and apoptosis-mediated cellular death induced by giganteosides D and E (Gig-D and Gig-E) and hederacolchisides A and A1 (Hcol-A and Hcol-A1) were analysed in HL-60 cells. MATERIALS AND METHODS The end-point metabolic (WST1) and lactate dehydrogenase (LDH) assays were used. Cell cycle analysis and apoptosis were measured by flow cytometry, DNA laddering and ...

Objective. To study the effects of extracts (SML-1, SML-2, SML-3 and SML-4) from Euonymus alatus Sied on cell proliferation and on renal tubular cell (Madin-Darby Canine Kidney, MDCK) injury induced by high concentration of glucose. Methods. MTT assay was used to evaluate the effects of herbal extracts on cell proliferation and viability in MDCK cells after exposure to high concentration of glu...

Epigallocatechin gallate (EGCG) is the principle antioxidant of the green tea extract. The effect of EGCG was studied against the hepatotoxicity induced by N-nitrosodiethylamine (NDEA) in rats. The male rats were exposed to NDEA (0.1 mg/ ml) dissolved in drinking water separately and along with 5, 10 and 15 mg/ml of EGCG for 21 days. The activity of serum aspartate amino transferase (AST), seru...

Lobar pneumonia, one of the community-acquired pneumonia (CAP), is a common pediatric low respiratory tract infection. Calpains are Ca2+-activated cysteine proteases whose activation mechanism is elusive. The present study was undertaken to detect the role and mechanism of calpains in pediatric lobar pneumonia. The human acute lung infection model (ALIM) was constructed and infected by Streptoc...

Hydroxyurea (HU) is the most important advance in the treatment of sickle cell anaemia (SCA) for preventing complications and improving quality of life for patients. However, some aspects of treatment with HU remain unclear, including their effect on and potential toxicity to other blood cells such as neutrophils. This study used the measurement of Lactate Dehydrogenase (LDH) and Methyl Thiazol...
