Ascorbic acid is one of the important water soluble vitamins. It is essential for collagen, carnitine and neurotransmitters biosynthesis. Most plants and animals synthesize ascorbic acid for their own requirement. However, apes and humans can not synthesize ascorbic acid due to lack of an enzyme gulonolactone oxidase. Hence, ascorbic acid has to be(More)
The neuropathologic sequelae of carbon monoxide (CO) toxicity have been well described in postmortem examinations. Globus pallidus damage as well as diffuse white matter lesions and encephalopathic changes occur. Brain CT has provided imaging correlates to the premortem changes. MRI is more sensitive and provides more specificity. Cerebral edema changes may(More)
Selective permeability across the blood-brain and blood-spinal cord barriers was studied in a rabbit experimental model. To maintain steady state levels of the tracers in the circulation, 50muCi each of [3H]-D-mannitol and [14C]-carboxyl-inulin were administered as a bolus and by slow intravenous infusion for 60, 90 and 120 minutes; 90 min proved to be the(More)
BACKGROUND Bitter cumin (Centratherum anthelminticum (L.) Kuntze), is a medicinally important plant. Earlier, we have reported phenolic compounds, antioxidant, and anti-hyperglycemic, antimicrobial activity of bitter cumin. In this study we have further characterized the antioxidative activity of bitter cumin extracts in various in vitro models. METHODS(More)
Human glioblastomas (gliomas) are characterized as highly invasive and rapidly growing brain tumors. In this study, we present data on in vitro effect of ascorbyl stearate (Asc-S), a liphophilic derivative of ascorbic acid on cell proliferation, transformation, apoptosis and modulation of expression of insulin-like growth factor-I receptor (IGF-IR) in human(More)
BACKGROUND Amyloidosis, oxidative stress and inflammation have been strongly implicated in neurodegenerative disorders like Alzheimer's disease. Traditionally, Caesalpinia crista and Centella asiatica leaf extracts are used to treat brain related diseases in India. C. crista is used as a mental relaxant drink as well as to treat inflammatory diseases,(More)
The pathophysiology of ischemia/reperfusion injury involves extravascular migration of leukocytes from the bloodstream to the site of injury. Leukocyte adhesion and intercellular adhesion molecule-1 (ICAM-1) play an important role in the recruitment of leukocytes to the site of injury. In this study, we evaluated the role of the ICAM-1 in spinal cord(More)
