BackgroundAcute menopausal syndrome especially hot flashes, is one of the most common gynecological problems during menopause. Due to the side effects of hormone therapy, herbal and complementary medicines are always of immense interest to people in the treatment and management of the symptoms and complications of menopause.ObjectiveThe aim of this study was to investigate the mechanisms and effects of medicinal plants employed in the treatment of menopausal symptoms.MethodsThis review article was carried out by examining clinical trial studies between the period of 1994 and 2016. The keywords, which include menopause, climacteric, hot flushes, flashes, herb and phytoestrogens were used to search for herbal medicines used in clinical trials for the treatment of menopausal symptoms using databases such as PubMed, Medline, Scopus, Google scholar, SID and Magiran.ResultsThe results of the study showed that the medicinal plants, which include Sage herb (Salvia officinalis), Lemon balm (Melissa officinalis), Valerina officinalis, Black cohosh (Cimicifuga racemosa), Fenugreek (Trigonella foenum-graecum), Black cumin (Nigella sativa), Vitex (Vitex agnus-castus), Fennel (Foeniculum vulgare), Evening primrose (Oenothera biennis), Ginkgo biloba, Alfalfa (Medicago sativa), Hypericum perforatum, Panax ginseng, Pimpinella anisum, Licorice (Glycyrrhiza glabra), Passiflora incarnata, Red clover (Trifolium pratense), and Glycine soja were effective in the treatment of acute menopausal syndrome with different mechanisms.ConclusionMedicinal plants can play an imperative role in the treatment of acute menopausal syndrome; however, further studies are required to buttress their efficacy in the treatment of acute menopausal syndrome.

The binding of ciprofloxacin to human serum albumin (HSA) in the presence and absence of silver nanoparticles of three sizes was investigated for the first time. For this purpose fluorescence spectroscopy, circular dichroism, UV-vis spectroscopy, and ζ potential techniques were employed under physiological conditions. The titration results indicated that ciprofloxacin quenched the fluorescence intensity of HSA through a static mechanism, but in the presence of Ag nanoparticles of sizes I and II there were two different kinds of interaction behavior. Results of circular dichroism indicated that the secondary structure of HSA was modified with increasing ciprofloxacin concentration. A comparison between resonance light scattering of binary and ternary systems allowed us to estimate the effect of silver nanoparticles on the initial formation and aggregation of ciprofloxacin with HSA. The ζ-potential results suggested induced conformational changes on HSA, thus confirming the experimental and theoretical results.

IntroductionSaccharomyces cerevisiae is known as one of the useful yeasts which are utilized in baking and other industries. It can be easily cultured at an economic price. Today the introduction of safe and efficient carriers is being considered. Due to its generally round shape, and the volume that is enclosed by its membrane and cell wall, it is used to encapsulate active materials to protect them from degradation or to introduce a sustained release drug delivery system. Providing the best conditions in order to achieve the best morphological properties of Saccharomyces cerevisiae as a carrier.MethodsIn this research, the most suitable growth condition of yeast cells which provides the best size for use as drug carriers was found by a bioreactor in a synthetic culture medium. Yeast cell reproduction and growth curves were obtained, based on pour plate colony counting data and UV/Visible sample absorption at 600 nm. Yeast cell growth patterns and growth rates were determined by Matlab mathematical software.ResultsResults showed that pH=4 and dissolving oxygen (DO) 5% was the best condition for yeast cells to grow and reproduce. This condition also provided the largest size (2 × 3 μ) yeast cells.ConclusionOwing to the yeast cells’ low-cost production and their structural characteristics, they could be used as potent drug carriers.FundingThis work was supported by a grant from the Vice Chancellor of Research of Mashhad University of Medical Sciences.

Background. Topical treatment of cutaneous leishmaniasis is an attractive alternative avoiding toxicities of parenteral therapy while being administered through a simple painless route. Recently liposomal formulations of amphotericin B have been increasingly used in the treatment of several types of leishmaniasis. Aims. The efficacy of a topical liposomal amphotericin B formulation was compared with intralesional glucantime in the treatment of cutaneous leishmaniasis. Methods. From 110 patients, the randomly selected 50 received a topical liposomal formulation of amphotericin B into each lesion, 3–7 drops twice daily, according to the lesion's size and for 8 weeks. The other group of 60 patients received intralesional glucantime injection of 1-2 mL once a week for the same period. The clinical responses and side effects of both groups were evaluated weekly during the treatment course. Results. Per-protocol analysis showed no statistically significant difference between the two groups (P = 0.317, 95% confidence interval (CI) = 1.610 (0.632–4.101)). Moreover, after intention-to-treat analysis, the same results were seen (P = 0.650, 95% CI = 0.1.91 (0.560–2.530)). Serious post treatment side effects were not observed in either group. Conclusions. Topical liposomal amphotericin B has the same efficacy as intralesional glucantime in the treatment of cutaneous leishmaniasis.

Pistacia atlantica is the main herbal medicine that has been widely used in the Middle Eastern and Mediterranean areas since ancient time. Pistacia atlantica has been used for multiple purposes like stomach diseases, renal disorders, wounds and coughs. The aim of this study is to review its botanical characterization, traditional applications, photochemistry effects and pharmacological activities. Data in this review article was gathered from credible pharmacopeias, electronic databases such as Web of Science, Science Direct, PubMed, EMBASE, Scopus, EBSCO, Google Scholar, SID and Iran Medex and textbooks of Persian medicine such as Canon of medicine (Ibn-e Sina, 980-1037 AD) and Makhzan-al-Advia (Aghili, 18th century). The keywords were searched in Persian and English books on medicinal plants and traditional medicine. The results showed that P. atlantica has many medicinal properties such as antioxidant, antidiabetic, antihyperlipidemic, along with others. It can also be effective in gastrointestinal diseases. Thus, different new drugs can be formulated based on P. atlantica for the management of various diseases.

Irritable Bowel Syndrome (IBS) is a chronic digestive disorder, which is characterized by abdominal pain, bloating, diarrhea and constipation periods. The etiology is unknown. Based on the different mechanisms in the etiology, treatment focuses on controlling symptoms. Due to the longtime of syndrome, inadequacy of current treatments, financial burden for patients and pharmacologic effects, several patients have turned to the use of complementary and alternative medicine (CAM). Complementary and alternative treatments for IBS include hypnosis, acupuncture, cognitive behavior therapy, yoga, and herbal medicine. Herbal medicines can have therapeutic effects and adverse events in IBS. The aim of this study was to evaluate the efficacy of herbal medicines in the control of IBS, and their possible mechanisms of action were reviewed. Herbal medicines are an important part of the health care system in many developing countries It is important for physicians to understand some of the more common forms of CAM, because some herbs have side effects and some have interactions with conventional drugs. However herbal medicines may have therapeutic effects in IBS, and further clinical research is needed to assess its effectiveness and safety.

BackgroundBerberine was encapsulated in yeast cells of Saccharomyces cerevisiae as novel carriers to be used in different food and drug industries. The microcapsules were characterized by differential scanning calorimetry (DSC), fourier transform infra red spectroscopy (FT-IR) and fluorescence microscopy. The encapsulation factors such as plasmolysis of yeast cells which affects the % encapsulation yield were studied.ResultsFluorescence microscopy showed the yeast cells became fluorescent after encapsulation process. DSC diagram was representing of new peak for microcapsule which was not the same as berberine and the empty yeast cells peaks, separately. FTIR spectrums of microcapsules and yeast cells were almost the same. The plasmolysed and non plasmolysed microcapsules were loaded with berberine up to about 40.2 ± 0.2% w/w.ConclusionAnalytical methods proved that berberine was encapsulated in the yeast cells. Fluorescence microscopy and FTIR results showed the entrance of berberine inside the yeasts. DSC diagram indicated the appearance of new peak which is due to the synthesis of new product. Although plasmolysis caused changes in yeast cell structure and properties, it did not enhance berberine loading in the cells. The results confirmed that Saccharomyces cerevisiae could be an efficient and safe carrier for active materials.

Sarcoidosis is a multisystem inflammatory disease with an etiology that is not clearly understood. Amongst the different organs that may be affected, the lungs are the most common. Musculoskeletal manifestations of the disease are uncommon. They include arthropathy, bone lesions, or myopathy, all of which may occur as initial symptoms or develop during the course of the disease. Articular involvement my present as arthralgia or arthritis. Skeletal complications usually develop in the chronic state of the disease. Muscular disease is rare and usually asymptomatic. Appropriate imaging modalities including X-ray, MRI, FDG-PET/CT assist in the diagnosis of rheumatic sarcoidosis. However, biopsy is necessary for definite diagnosis. In most cases of musculoskeletal involvement, NSAIDs and corticosteroids are sufficient for symptomatic management. For more resistant cases immunosuppressive drugs (i.e., methotrexate) and TNF-? inhibitors are used. Our aim is to review various types of musculoskeletal involvement in sarcoidosis and their existing treatment options.
