AB  - Topical treatment of skin infections is often limited by drawbacks related to both antimicrobial agents and their vehicles. In addition, considering the growing promotion of natural therapeutic products, our objective was to develop and evaluate naturally-based emulsion system, as prospective topical formulation for skin infections-treatment. Therefore, alkyl polyglucoside surfactants were used for stabilization of a vehicle serving as potential carrier for supercritical CO2-extract of Usnea barbata, lichen with well-documented antimicrobial activity, incorporated using two protocols and three concentrations. Comprehensive physicochemical characterization suggested possible involvement of extracts particles in stabilization of the investigated system. Raman spectral imaging served as the key method in disclosing extracts particles potential to participate in the microstructure of the tested emulsion system via three mechanisms: (1) particle-particle aggregation, (2) adsorption at the oil-water interface and (3) hydrophobic particle-surfactant interactions. Stated extract-vehicle interaction proved to be correlated to the preparation procedure and extract concentration on one hand and to affect the physicochemical and biopharmaceutical features of investigated system, on the other hand. Thereafter, formulation with the best preliminary stability and liberation profile was selected for further efficiency and in vivo skin irritation potential evaluation, implying pertinent in vitro antimicrobial activity against G+ bacteria and overall satisfying preliminary safety profile.

AB  - Antimicrobial activity of Usnea barbata especially against bacteria involved in pathogenesis of various skin conditions has been well documented in literature. Nevertheless, there are no papers dealing with formulation of its isolates into topical preparations for treatment of skin infections. In present study, alkyl polyglucoside (APG)-based vehicle was developed as carrier of U. barbata CO2-supercritical extract (U-SE) that demonstrated the best anti- microbial potential in preliminary screening. For comparison, chosen extract in the same concentration and using the same procedure was incorporated into a pharmacopoeial vehicle. Comparative evaluation of physicochemical stability, efficiency and safety proved APG-based vehicle to possess certain preferential features as carrier of U-SE compared to the reference one, composing a topical formulation with potential clinical relevance in treatment of skin infections.
AB  - Antimikrobna aktivnost vrste Usnea barbata naročito protiv bakterija koje učestvuju u patogenezi različitih bolesti kože, dobro je dokumentovana u naučnoj literaturi. Uprkos tome, ne postoje radovi koji se bave formulacijom topikalnih preparata na bazi ovog lišaja namenjenih lečenju kožnih infekcija. U ovoj studiji, razvijena je podloga stablizovana alkil poliglukozidnim (APG) emulgatorom, kao potencijalni nosač za ekstrakt vrste U. barbata koji je pokazao najbolji antimikrobni potencijal u preliminarnom istraživanju nekoliko ekstrakata dobijenih upotrebom različitih ekstragenasa/postupaka. Radi poređenja, odabrani CO2-natkritični ekstrakt je inkorporiran u istoj koncentraciji (koja odgovara 2 mas.% usninske kiseline) i istim postupkom izrade u često korišćenu podlogu farmakopejskog kvaliteta, a zatim je sprovedeno uporedno istraživanje fizičko-hemijske stabilnosti, efikasnosti i bezbednosti na obe grupe uzoraka. Rezulati našeg istraživanja pokazali su da se razvijena podloga stabilizovana APG emulgatorom može smatrati pogodnim nosačem za CO2-natkritični ekstrakt vrste U. barbata, čineći topikalnu formulaciju sa potencijalnim kliničkim značajem u terapiji kožnih infekcija. Reološka istraživanja pokazala su zadovoljavajuću sposobnost emulzije stabilizovane APG emulgatorom da ostane fizički stabilna nakon dodatka CO2-natkritičnog ekstrakta vrste U. barbata, u poređenju sa farmakopejskom. Međutim, konduktometrijska merenja su pokazala određena neslaganja sa reološkim nala- zima, namećući potrebu za dodatnim istraživanjima radi konačne procene fizičke stabilnosti testiranih emulzionih sistema. Izmerene vrednosti pH tokom perioda od 90 dana čuvanja uzoraka na sobnoj temperaturi ukazale su na zadovoljavajuću preliminarnu hemijsku stabilnost svih uzoraka. Dalja istraživanja efikasnosti i bezbednosti pokazala su bolji antimikrobni potencijal uzoraka sa podlogom stabilizovanom APG emulgatorom u odnosu na tradicionalno upotrebljavanu farmakopejsku bazu poznatog kvaliteta. Zadovoljavajući preliminarni bezbedonosni profili su pokazani kako za uzorke stabilizovane APG emulgatorom tako i za referentne krem uzorke. Na osnovu navedenog, može se zaključiti da je istraživana podloga bazirana na APG emulgatoru pokazala određene povoljnije karakteristike kao nosač za CO2-natkritični ekstrakt vrste U. barbata u poređenju sa konvencionalno korišćenom podlogom, naročito uzimajući u obzir njene poboljšane senzorne karakteristike, kao osobinu koja je često odlučujuća za komplijansu pacijenata.

AB  - Oleum Hyperici, the oil extract of St. Johns Wort (SJW), is one of the oldest folk remedies, traditionally used in the topical treatment of wounds, bruises, ulcers, cuts, burns, hemorrhoids and also as an antiseptic. Considering the advantageous characteristics of emulsion applications, in the present study we have formulated three O/W creams containing 15% (w/v) of SJW oil extract as an active ingredient. The aim was to estimate dermatological application of the prepared creams for the abovementioned indications. The extracts were prepared according to the prescriptions from traditional medicine, however with different vegetable oils used as an extractant, namely: Olive, palm and sunflower oil. The investigated O/W creams demonstrated significant antiinflammatory effects in an in vivo double-blind randomized study, using a sodium lauryl sulphate test. Both skin parameters assessed in the study (electrical capacitance and erythema index), were restored to the baseline value after a seven-day treatment with the tested creams. Almost all investigated SJW oil extracts and corresponding creams displayed the same antimicrobial activity against the most of the investigated microorganisms with obtained minimal inhibitory concentrations values of 1,280 mu g/mL, 2,560 mu g/mL or >2,560 mu g/mL.
