How to characterize an antioxidant: an update.
Author Halliwell B Date 1995 Journal Biochem Soc Symp Abstract The term antioxidant is widely used but rarely defined. One suggested definition is that an antioxidant is ‘a substance that, when present at low concentrations compared with those of an oxidizable substrate, significantly delays or prevents oxidation of that substrate’. Many substances have been suggested […]
Vaginal flora and pelvic inflammatory disease.
Author Faro S, Martens M, Maccato M Date 8/1993 Journal Am J Obstet Gynecol Abstract Forty-one patients with acute pelvic inflammatory disease were evaluated for the coexistence of bacterial vaginosis. Because all patients had a copious purulent vaginal discharge, microscopic criteria could not be used and microbiologic criteria were employed. The vaginal bacterial flora were […]
Free radicals scavenging action and anti-enzyme activities of procyanidines from Vitis vinifera. A mechanism for their capillary protective action.
Author Maffei Facino R, Carini M, Aldini G Date 5/1994 Journal Arzneimittelforschung Abstract The scavenging by procyanidines (polyphenol oligomers from Vitis vinifera seeds, CAS 85594-37-2) of reactive oxygen species (ROS) involved in the onset (HO degrees) and the maintenance of microvascular injury (lipid radicals R degrees, RO degrees, ROO degrees) has been studied in phosphatidylcholine […]
In vitro and in vivo wound healing activity of asiaticoside isolated from Centella asiatica.
Author Shukla A, Rasik AM, Jain GK, Shankar R, Kulshrestha DK, Dhawan BN. Date 4/1999 Journal J Ethnopharmacol Abstract The activity of asiaticoside, isolated from Centella asiatica, has been studied in normal as well as delayed-type wound healing. In guinea pig punch wounds topical applications of 0.2% solution of asiaticoside produced 56% increase in hydroxyproline, […]
Adrenocortical insufficiency.
Author Burke CW. Date 11/1985 Journal Clin Endocrinol Metab Abstract Adrenocortical insufficiency causes difficulty in diagnosis and morbidity out of proportion to its rarity, because of the non-specific, multi-system nature of the clinical features. Most of these are due to cortisol deficiency. Prominent features are well-known ones such as weight loss and asthenia, and hypoglycaemia. […]
The tender tooth. Dentoalveolar, pericoronal, and periodontal infections.
Author Kureishi A,Chow AW Date 3/1988 Journal Infect Dis Clin North Am Abstract Dental caries and periodontal disease are the most common afflictions of the tooth. These infectious diseases cause considerable pain and discomfort and ultimately loss of the tooth. Apart from local effects, these infections may extend beyond natural barriers and result in complications […]
The effect of controlled ascorbic acid depletion and supplementation on periodontal health.
Author Leggott PJ, Robertson PB, Rothman DL Date 8/1986 Journal J Periodontol Abstract To determine if systemic levels of vitamin C influence periodontal health, changes in plaque accumulation, gingival health and periodontal probing depth were measured in healthy subjects housed for 3 months in a nutrition suite that provided controlled periods of ascorbic acid depletion […]
Evaluation of antioxidant activity by chemiluminescence.
Author Hirayama O, Takagi M, Hukumoto K Date 1/5/1997 Journal Anal Biochem Abstract A sensitive and simple chemiluminescent method for measuring antioxidant activity was developed. The method is based on antioxidant-dependent quenching of chemiluminescence generated from lipid hydroperoxide and isoluminol/microperoxidase reagent. This method was used to evaluate the antioxidant ability of various antioxidants by measuring […]
[Histamine-release and migraine]
Author Launay JM, Pradalier A, Haimart M, Artigou C, Dreux C, Dry J. Date 5/1987 Journal Rev Med Interne Abstract Some studies suggested a role for histamine in the pathogenesis of the migraine. So we decided to investigate the histamine-release in two groups of patients: 8 common migraine patients, 8 healthy subjects. Plasma from either […]
Feverfew in rheumatoid arthritis: a double blind, placebo controlled study.
Author Pattrick M, Heptinstall S, Doherty M Date 7/1989 Journal Ann Rheum Dis Abstract Feverfew, reputed by folklore to be effective in arthritis, has in vitro properties that could be beneficial in the control of inflammatory disease. Forty one female patients with symptomatic rheumatoid arthritis received either dried chopped feverfew (70-86 mg) or placebo capsules […]
