Abstract
Background and Aim: Bacteria are one of the causes of nail infections. Although nail infections are not always associated with a major health problem, their treatment, particularly in immunosuppressed patients could be chalenging. This study was conducted to investigate the prevalence of bacterial agents in patients with dystrophic nails referred to mycology laboratory of Razi Hospital, Tehran.
Methods: This was a cross-sectional study on patients with dystrophic nail. Samples were examined by both direct examination and culture. Blood agar and eosin methylene blue (EMB) agar media were used to culture and differentiate bacteria.
Results: Of 700 dystrophic nail samples, 183 (26.1%) samples were diagnosed as onychomycosis. One hundred and four (56.8%) of the patients were female. One hundred and eighty-one patients had bacterial nail infection (25.9%), of whom 109 (60.2%) were female. Forty-six (6.6%) patients had both bacterial and fungul infections, of whom 32 (69.6%) were female. The most common detected agent was Staphylococci.
Conclusion: Bacterial infections can result in dystrophioc nails. If these infections remain untreated they can lead to nail loss. In most cases, treatment of bacterial nail infections is easier than fungul nail infections.

Abstract
Background and Aim: The use of medicinal herbs for the treatment of skin disease, such as acne, has a long history. The extract of Pistaca atlantica is used to treat various diseases. This study was designed to evaluate the short-term efficacy and safety of Pistaca atlantica extract for the treatment of mild to moderate acne.
Methods: This clinical trial was performed on 60 patients with mild to moderate acne, who where randomly divided into two groups. After obtaining informed consent, volunteers in the case group received a topical extract of 15% Pistaca Atlantica once daily for 6 weeks. In the control group, placebo was given in the same way. Patients were evaluated for the number of lesions at the beginning, and 3 and 6 weeks after treatment.
Results: At the end of study, the mean reduction in lesions was 59.93% in the Pistaca atlantica group and -11.46% in the control group. Also Skin softness and lucidity were observed in the Pistaca atlantica group.
Conclusion: This clinical study showed that topical treatment with Pistaca atlantica extract can be recommended to improve mild to moderate acne. However, a longer study with larger sample size is needed to achieve a comprehensive evaluation of the efficacy and safety of this plant.

Abstract
Today, the valuable metabolites of microalgae are widely used in the production of many cosmetic products, as the biomass of algae contains pigments, proteins, essential fatty acids, polysaccharides, vitamins and minerals, all of which are present in both natural foods and cosmetics are used. In fact, these secondary metabolites with anti-blemish and anti-microbial, anti-aging, sunscreen and skin whitening effects can repair and heal the skin and protect the skin from UV damage and prevent inflammation. Existing cosmetics can in many cases be replaced with microalgae-derived cosmetics that are environmentally friendly as well as safe. The effects of microalgae and their derivatives have been tested in various nutritional studies around the world. However, there are very few studies on their cosmetic applications, so in this review article we tried to study several species of microalgae, cultivation methods, use of biomass and bioactive molecules derived from microalgae in the production of anti-aging products, sunscreen and skin whitening in the formulation of cosmetic compounds.

Abstract
Microalgae are photosynthetic microorganisms which are the result of permanent exposure to stressful conditions such as high or low temperature, high salinity, osmotic pressure, ultraviolet radiation (uv), contain valuable bioactive compounds in cosmetic products .the existing cosmetic products can be replaced with the cosmetic products that are compatible with the environment and can be included in the topical formulations of skin care such as moisturizers, Anti-wrinkles, anti - aging and anti - acne. In addition, the extracts from these microalgae are used to make sunscreen to treat skin pigmentation and improve wounds; therefore most commercial cosmetics have a wide range of natural compounds extracted from cyanobacteria and this leads to increasing antioxidant, regenerative, moisturizer, shielding and brighteners for both hair and skin. In this article the cosmetic use of cyanobacteria extract and dried powder in improving the appearance and health skin have been investigated. Furthermore, analyzing the brand of Spirulina has been discussed.

Abstract
Treatment of chronic conditions like diabetic foot ulcer (DFU) is challenging due to increased susceptibility for infection and delayed wound healing. Complexity of existing therapy, adverse effects and microbial resistance emphasizes the need of an alternative approach for the management of DFU. The increasing body of evidence associated with probiotic application in diverse disease states merits its use in wound healing and infection too. Different probiotic strains have shown their efficacy in various infections like gut infections, oral infections and urogenital infections. Experimental studies have demonstrated probiotics’ ability for gastric ulcer healing. Underlying mechanism of the above therapeutic effects of probiotics involves modulation of local and systemic immunity. The hypothesis is based on the concept that mechanism of anti-infective and ulcer healing action of probiotics will be similar in peripheral wounds and ulcers as on any other part of the body. This paper focuses on the hypothesis that topical formulation of probiotics may be effective for the treatment of diabetic foot ulcers.
