The antiulcer effects of 3,5,7-trihydroxy-2-(3,4-dihydroxyphenyl)-1-benzopyrylium chloride (IdB 1027) were assessed in various experimental models. Given orally, IdB 1027 antagonized gastric ulcerations induced by pylorus ligation, stress, nonsteroidal antiinflammatory drugs, ethanol, reserpine, histamine and duodenal ulceration induced by mercaptamine(More)
Cellulite is thought to affect 80-90% of postpubertal women, and is considered much of a cosmetic concern by the large majority of them. In this study, the objective was to assess the efficacy of a topical cosmetic product containing various active ingredients of botanical origin on cellulite blemishes on female volunteers affected by fat accumulations, as(More)
The intestinal effects of (+)-glaucine [(S)-1,2,9,10-tetramethoxyaporphine] were studied using the guinea-pig ileum. (+)-Glaucine (10-300 microM) induced ileal contractions. The contraction was not affected by tetrodotoxin, atropine, hexamethonium, propranolol, naloxone, methysergide, N(G)-nitro-L-arginine methyl ester, SR141716A (a cannabinoid CB1 receptor(More)
A Vaccinium myrtillus anthocyanosides preparation (equivalent to 25% of anthocyanidins) demonstrated significant vasoprotective and antioedema properties in exerimental animals. In rabbits, the skin capillary permeability increase, due to chloroform, was reduced both after i.p. (25--100 mg/kg) and oral administration (200--400 mg/kg) of anthocyanosides.(More)
The effects of 3,5,7-trihydroxy-2-(3,4-dihydroxyphenyl)-1-benzopyrylium chloride (IdB 1027) on the rat gastric mucosa were evaluated. IdB 1027 administered intragastrically at doses ranging from 100 to 400 mg/kg inhibited the fall in transmucosal potential difference and the increase in H+ back-diffusion induced by acetylsalicylic acid. Moreover, IdB 1027(More)
Disodium salts of the dihemiphthalates of urs-12-ene-3 beta, 28-diol 3b and of ursa-9(11), 12-diene-3 beta,28-diol 4b were synthesized from uvaol and examined for their gastroprotective activity in rats. The effects showed by 3b and 4b, given p.o. in two antiulcer tests (ethanol induced gastric lesions and diclofenac induced gastric ulcers), were 5-25 times(More)
Polinacea is a new standardized hydroethanolic extract obtained from Echinacea angustifolia roots containing echinacoside (>4%), the high molecular weight polysaccharide IDN 5405 (>5%) and a isobutylamide fraction (<0.1%). For in vitro tests, a bacterial lipopolysaccharide-free (LPS-free) Polinacea has been prepared in order to avoid non-specific responses(More)
