Acne can occur due to increased sebum excretion, inflammation of the skin triggered by bacteria Propionibacterium acnes, Staphylococcus epidermidis, aureus. The purpose this study was determine formulation sheet mask preparations bandotan leaf extract (Ageratum conyzoides L.) in inhibiting growth acnes bacteria. This type research is an experimental which include plant identification, making et...

The disease has four main causes: sebaceous hyperplasia and hyperseborrhoea; hyperkeratinization and consequent keratinocyte accession; colonization of Propionibacterium acnes (P. acnes) and respective Staphylococcus albus and inflammation and immune response. The production of sebum by sebocytes is stimulated by androgens, such as testosterone, which in turn stimulate the production of sebocyt...

This study was aimed to depict potential effects of stable formulation (water in oil emulsion), containing 3% green tea (Camellia sinensis L) extract on skin sebum production in healthy human volunteers. For this purpose formulation was designed using 3% ethanolic green tea extract and Abil®EM90 was used as an emulsifier. Formulation was applied to the cheeks of healthy human volunteers (n=10) ...

The chemical composition of the gland-pad sebum of gerbils of both sexes is analysed using gas-liquid chromatographical and mass spectroscopical techniques and compared with the lipids from distal skin areas. Cholesterol esters, with (omega-1)-methyl-substituted fatty acids as acidic constituents, were shown to occur in the gland-pad sebum of both sexes in high concentrations, whereas cholesta-...

This fluorometric procedure for determining selenium in human serum or urine is sensitive (requiring only 0.4 mL of sample), accurate, simple, and can be performed on several samples concurrently. Using this technique, we found a mean selenium concentration in the serum of normal Canadian men of 142.9 (SD 16.1) micrograms/L. The mean urinary excretion rate was 124.5 (SD 76.0) micrograms/day.

This study was aimed to investigate the effects of cream containing Ficus carica L. fruit (Fig) extract on various skin parameters such as skin melanin, erythema, moisture content, trans-epidermal water loss and sebum. For this purpose, formulation with 4% concentrated extract of F. carica fruit and base without extract were developed. Base served as a control. Both base and formulation were ap...

The aim of the present work was to obtain information on the total urinary fluoride concentration and excretion of Venezuelan children at the age of 3 to 5 years, as part of a program to monitor fluoride ingestion. A 24 hour urine sample was collected from each of 63 children, between 3 and 5 years of age and analyzed for (i) total urinary volume (ml), (ii) urinary flow rate (ml/h), (iii) fluor...

At equivalent oral doses, cefadroxil has a longer serum half-life, slower urinary excretion rate, greater area under the serum level versus time curve than cephalexin or cephradine, and peak serum concentrations that are 75 to 80% those of cephalexin. The calculated, apparent in vivo volume of distribution of cefadroxil is greater than that of cephalexin. These properties infer greater persiste...

BACKGROUND Although photodynamic therapy (PDT) is widely performed for acne, little is known about its exact therapeutic mechanism. OBJECTIVE We aimed to estimate the efficacy and safety of PDT on acne and to discover its mode of action. METHODS We performed PDT on 12 patients with mild to moderate acne. The clinical efficacy was assessed by counting the acne lesions and measuring the sebum...
