| extraction, separation and isolation of volatiles from vitex agnus-castus l. (verbenaceae) wild species of sardinia, italy, by supercritical co2. | isolation of volatile concentrates from leaves, flowers and fruits of vitex agnus-castus l. have been obtained by supercritical extraction with carbon dioxide. the composition of the volatile concentrates has been analysed by gc/ms. in all plant organs, the extracts are composed chiefly of alpha-pinene, sabinene, 1,8-cineole, alpha-terpinyl acetate, (e)-caryophyllene, (e)-beta-farnesene, bicyclogermacrene, spathulenol and manool. the main difference observed was in the content of sclarene, which ... | 2010 | 20397107 |
| tinea capitis in children in the district of cagliari, italy. | between 1986 and 1995, 4104 children were observed in the clinic of dermatology in cagliari, italy. three hundred and thirty-six children (8.2%), 188 boys and 148 girls, aged 1 month to 13 years, were affected by tinea capitis. microsporum canis was detected in 278 cases (82.7%) and trichophyton mentagrophytes in 58 cases (17.3%). systemic treatment with 20-25 mg kg-1 day-1 griseofulvin led to complete recovery in 30-40 days. none of the patients relapsed. the epidemiology of the infection was a ... | 1997 | 9476495 |
| tinea capitis in adults. | between 1973 and 1994, 17 cases of tinea capitis in adults were observed in the dermatology clinic of the university of cagliari (italy). the patients were all women (age range 17-76 years) and came from the district of cagliari. at the time of referral, they presented with a disease duration varying from 8 to 10 months. the main clinical feature was scalp lesions, but in two cases mycotic lesions on the face were also present. the following dermatophytes were isolated: microsporum canis (eight ... | 1996 | 9009649 |
| Antifungal activity and chemical composition of essential oils from Smyrnium olusatrum L. (Apiaceae) from Italy and Portugal. | The essential oils and supercritical CO(2) extracts of wild Smyrnium olusatrum L. growing in Sardinia (Italy) and in Portugal were investigated. For the study, oils were isolated from total plant aerial part (umbels containing seeds). The content of ß-phellandrene (67.3% vs. 42.7%) and a-pinene (31.9% vs. 1.2%), respectively, the main components of Portuguese and Italian essential oils, declined during the maturation stage of the umbels. Contrarily, some other important components, particularly ... | 2011 | 21902563 |
| chemical composition and biological assays of essential oils of calamintha nepeta (l.) savi subsp. nepeta (lamiaceae). | aerial parts of wild calamintha nepeta (l.) savi subsp. nepeta growing spontaneously on the mediterranean coast (sardinia island, italy) and on the atlantic coast (portugal) were used as a matrix for the supercritical extraction of volatile oil with co(2). the collected extracts were analysed by gc-fid and gc-ms methods and their compositions were compared with that of the essential oil isolated by hydrodistillation, but the differences were not relevant. a strong chemical variability was observ ... | 2010 | 20981614 |
| kerion celsi: a clinical epidemiological study. | we present a case record of patients with kerion celsi observed in the clinic of dermatology, university of cagliari (italy) from 1981 to 1995. altogether, 31 children (18 male and 13 female) with an age range of 40 days to 12 years were studied. in all cases the lesions were confined to the scalp. in 10 cases the disease developed as such, while in 21 patients it represented the inflammatory evolution of tinea capitis secondary to incongruous topical treatment. microsporum canis was isolated in ... | 1998 | 9670770 |
| chemical characterisation and biological activity of leaf essential oils obtained from pistacia terebinthus growing wild in tunisia and sardinia island. | in the present work the chemical compositions, measured by gc and gc-ms, of the essential oils obtained by hydrodistillation from leaves of pistacia terebinthus collected in bizerte (tunisia) and baunei (italy) are reported. both essential oils possessed high content of monoterpene hydrocarbons (86.3% and 90.9%, respectively), being α-pinene (62.4 vs. 35.0)%, camphene (3.0 vs. 2.4)%, β-pinene (12.1 vs. 4.5)%, terpinolene (1.7 vs. 35.2)% and β-phellandrene (3.8 vs. 4.5)% the main components. the ... | 2017 | 28278668 |
| tinea faciei due to microsporum canis in children: a survey of 46 cases in the district of cagliari (italy). | dermatophytoses are frequent in children, but involvement of the facial skin has peculiar aspects that should be considered a separate entity: tinea faciei. microsporum canis infection in tinea faciei has not been widely documented. to review cases of tinea faciei due to m. canis in children diagnosed at the dermatology clinic, university of cagliari. between 1990 and 2009, all children with dermatophyte infections of the facial skin were recruited for the study after parental consent. diagnosis ... | 2011 | 22011084 |
| a 20-year survey of tinea faciei. | tinea faciei is an uncommon dermatophytosis affecting the glabrous skin of the face. between 1988 and 2007 at the dermatology department of cagliari university, 107 cases of tinea faciei have been diagnosed, involving 72 females and 35 males, aged 2-72 years. incidence peaks were observed between 6 and 15 years (48.59%) and between 36 and 45 years (17.76%). males below and females above 15 years of age were the most affected. in 61 patients (57.1%), typical forms of tinea faciei were observed, w ... | 2010 | 19563490 |
