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 […]

Author Davies LP, Drew CA, Duffield P Date 8/1992 Journal Pharmacol Toxicol Abstract Kava, an intoxicating beverage prepared from the pepper plant Piper methysticum, is widely consumed by the indigenous peoples in the islands of the South Pacific. As the first of a series of studies on the neuropharmacological interactions of kava with CNS receptors […]
Amino acid sequence of sweet-taste-suppressing peptide (gurmarin) from the leaves of Gymnema sylvestre.
Author Kamei K, Takano R, Miyasaka A, Imoto T Date 1/1992 Journal J Biochem (Tokyo) Abstract The complete amino acid sequence of a sweet-taste-suppressing peptide, gurmarin, from the leaves of Gymnema sylvestre was determined by the Edman analysis of peptides derived from digests obtained with Staphylococcus aureus V8 protease, pyroglutamyl aminopeptidase, and lysyl endopeptidase. Gurmarin […]
Antiandrogenic effects of a flavonoid-rich fraction of Vitex negundo seeds: a histological and biochemical study in dogs.
Author Bhargava SK Date 12/1989 Journal J Ethnopharmacol Abstract The ability of the flavonoid-rich fraction (5,7,3′-trihydroxy, 6,8,4′- trimethoxy flavones) of Vitex negundo seeds to antagonize the androgen action of exogenous testosterone propionate on the male reproductive system was studied in castrated prepubertal and intact adult dog. The flavonoid-rich fraction (F) was administered 10 mg/kg i.p. […]
The Ginkgo biloba extract, EGb761, increases synaptosomal uptake of 5- hydroxytryptamine: in-vitro and ex-vivo studies.
Author Ramassamy C, Christen Y, Clostre F Date 11/1992 Journal J Pharm Pharmacol Abstract The Ginkgo biloba extract (EGb 761) added to a synaptosomal fraction prepared from mice cerebral cortex modified [3H]5-hydroxytryptamine ([3H]5-HT) uptake in a biphasic manner. Between 4 and 16 micrograms mL-1 EGb 761 increased significantly the [3H]5-HT uptake (maximum + 23%). A […]
Reduced active thyroid hormone levels in acute illness.
Author Burger A, Nicod P, Suter P, Vallotton MB Date 3/1976 Journal Lancet Abstract In acute and subacute disease the active thyroid hormones, triiodothyronine (T3) and tetraiodothyroacetic acid (tetrac), are decreased while serum-thyroxine (T4) levels tend to be slightly reduced. Conversely, the inactive metabolite, reverse triiodothyronine (reverse T3), is increased indicating a diversion of T4 […]
Oleuropein protects low density lipoprotein from oxidation.
Author Visioli F, Galli C Date 1994 Journal Life Sci Abstract The Mediterranean diet, rich in fruit, vegetables, grain, and vegetable oil (mainly olive oil) is correlated with a lower incidence of coronary heart disease (CHD). Natural antioxidants contained in the Mediterranean diet might also play a role in the prevention of cardiovascular diseases, through […]
