Dermatophytosis, which is caused mainly by genera ofTrichophyton,Epidermophyton, andMicrosporum, is a frequent dermatological problem in tropical and subtropical countries. Investigations were carried out in this study to evaluate the antidermatophytic activity of the stems, leaves, and seeds ofCroton tiglium, one of the traditional medicine plants indigenous to Asia. Ethanolic extracts of the stems, leaves, and seeds ofC. tigliumwere prepared by cold soak or heat reflux methods. The antidermatophytic activities of the extracts were evaluated by disc diffusion and microdilution susceptibility assays againstTrichophyton mentagrophytes,T. rubrum, andEpidermophyton floccosum. The active components in the extracts were analyzed and identified by GC-MS. All ethanolic extracts ofC. tigliumshowed some antifungal activities against the three dermatophytes. The ethanolic stem extract had the greatest inhibitory activities againstT. mentagrophytesandE. floccosumwith MICs at 0.16 mg/mL and had a lower activity againstT. rubrum(MIC: 0.31 mg/mL). Oleic acid and hexadecanoic acid were found to be the major constituents in the stem extract that demonstrated strong antidermatophytic activities. The ethanolic extracts of stem or seed ofC. tigliumexhibit strong antidermatophytic activities and, thus, could be considered for application on treating skin fungal infections after appropriate processing.

Fungal infections caused by Trichophyton mentagrophytes, Aspergillus fumigatus , and Malassezia pachydermatis are among the major contributors to multisystemic health problems such as dermatitis, otitis, and respiratory disorders among humans and animals. This study was conducted to determine the in vitro antifungal activity of Terminalia catappa leaf crude aqueous and ethanolic extracts against these fungal pathogens by measuring the zone of inhibition (ZI) using the agar well diffusion technique. Qualitative phytochemical screening tests were also performed to determine bioactive compounds present in the plant extract. Results show that the plant’s crude aqueous (CAE) and ethanolic extracts (CEE) were found to be effective against all test fungi. M. pachydermatis showed susceptibility towards CAE and CEE from T1 (100%), T2 (75%), T3 (50%) and T4 (25%), with the highest mean ZI of 18.33mm and 13.33, respectively. On the other hand, T. mentagrophytes was inhibited by CAE and CEE at T1 (100%), T2 (75%) and T3 (50%) with the highest mean ZI of 9.67mm and 10.33mm, respectively. At the same time, it was observed that A. fumigatus had reactive sensitivity towards CAE and CEE at T1 (100%) and T2 (75%), with the highest mean ZI of 9.33mm and 10.33mm, respectively. Moreover, phytochemical tests showed that the plant’s leaf crude extracts contain alkaloids, saponins, and tannins, which could potentially inhibit fungal growth.

Tea-tree oil (oil of Melaleuca alternifolia) has recently received much attention as a natural remedy for bacterial and fungal infections of the skin and mucosa. As with most naturally occurring agents, claims of effectiveness have been only anecdotal; however, several published studies have recently demonstrated tea-tree oil's antibacterial activity. This study was conducted to determine the activity of tea-tree oil against 58 clinical isolates: Candida albicans (n = 10), Trichophyton rubrum (n = 8), Trichophyton mentagrophytes (n = 9), Trichophyton tonsurans (n = 10), Aspergillus niger (n = 9), Penicillium species (n = 9), Epidermophyton floccosum (n = 2), and Microsporum gypsum (n = 1). Tea-tree oil showed inhibitory activity against all isolates tested except one strain of E floccosum. These in vitro results suggest that tea-tree oil may be useful in the treatment of yeast and fungal mucosal and skin infections.

AbstractApplication of 5-fluorouracil (5-FU) in cholangiocarcinoma (CCA) is limited by adverse side effects and chemoresistance. Therefore, the combination therapy of 5-FU with other substances, especially natural products may provide a new strategy for CCA treatment. The aim of this study was to evaluate the combination effects of 5-FU and two ethanolic extracts of Thai noni juice (TNJ) products on CCA cell lines and nude mice xenografts. The results of antiproliferative assay showed the combination treatment of 5-FU and each TNJ ethanolic extract exerted more cytotoxicity on CCA cells than either single agent treatment. Synergistic effects of drug combinations can enable the dose reduction of 5-FU. The mechanism underlying a combination treatment was apoptosis induction through an activation of p53 and Bax proteins. In the nude mouse xenograft model, combination treatments of 5-FU with each TNJ ethanolic extract suppressed the growth of CCA cells implanted mice more than single agent treatments with no effects on mouse body weight, kidney, and spleen. Moreover, low doses of TNJ ethanolic extracts reduced the hepatotoxicity of 5-FU in nude mice. Taken together, these data suggested that the ethanolic extracts of TNJ products can enhance the anti-CCA effect and reduce toxicity of 5-FU.

Uncaria tomentosa (Willd.) DC is a woody climber species originating from South and Central America that has been used in the therapy of asthma, rheumatism, hypertension, and blood purification. Our previous study showed that U. tomentosa extracts altered human erythrocyte shape, which could be due to incorporation of the compounds contained in extracts into the erythrocyte membrane. The aim of the present study was to determine how the compounds contained in U. tomentosa extracts incorporate into the human erythrocyte membrane. The study has assessed the effect of aqueous and ethanolic extracts from leaves and bark of U. tomentosa on the osmotic resistance of the human erythrocyte, the viscosity of erythrocyte interior, and the fluidity of erythrocyte plasma membrane. Human erythrocytes were incubated with the studied extracts in the concentrations of 100, 250, and 500 µg/mL for 2, 5, and 24 h. All extracts tested caused a decrease in erythrocyte membrane fluidity and increased erythrocyte osmotic sensitivity. The ethanolic extracts from the bark and leaves increased viscosity of the erythrocytes. The largest changes in the studied parameters were observed in the cells incubated with bark ethanolic extract. We consider that the compounds from U. tomentosa extracts mainly build into the outer, hydrophilic monolayer of the erythrocyte membrane, thus protecting the erythrocytes against the adverse effects of oxidative stress.

Objective: As per the ethnopharmacological information has Butea monosperma been used to treat diabetes mellitus by the tribal people of tropical and subtropical areas. However, there is no much more scientific report available about the antidiabetic property of the leaves of the plant. Hence, the study was undertaken to evaluate the antidiabetic effect of ethanolic extract of B. monosperma on blood levels of adrenaline-induced and glucose feed diabetic rabbits.Methods: The three different doses of the extracts (100, 200, and 400 mg/kg) were administered orally to an experimental animal. The animals were induced diabetics by adrenaline and high glucose diet. Blood glucose level was measured accordingly. For antidiabetic activity, photocolorimeter was used to monitoring the blood glucose level with crest kit box (GOP-POD method).Results: The extracts showed considerable dose-dependent activity. However, the dose 400 mg/kg showed considerable lower of blood glucose level. p<0.01 indicates the significance result. 8 hrs reading 182.5±3.83 for 400 mg does is most effective for reducing blood sugar.Conclusion: The study indicates that the ethanolic extract of B. monosperma leaves possesses antidiabetic properties which suggest the presence of biologically active components.

Background: Dermatophytosis is one of the most common fungal infections in humans. Antifungals such as fluconazole are effectively used for treating dermatophytosis; however, drug resistance was observed in many cases. Therefore, a newer treatment strategy is essential. Methods: This study (Conducted in the Laboratory of the School of Public Health, Tehran University of Medical Sciences, Tehran, Iran in 2018) evaluated the antifungal susceptibility of nano fluconazole compared to conventional fluconazole on dermatophyte isolates using CLSI M38-A2guidelines. Dermatophyte species isolated from clinical cases of dermatophytosis were identified using PCR sequencing techniques. Zeta potential and size of the nano particles containing fluconazole were measured; scanning electron microscope (SEM) was used to determine nano particle structure. Results: The size of liposomal fluconazole obtained was 88.9  12.14 nm with –20.12  3.8 mV for zeta potential. The encapsulation rate for fluconazole was 75.1  4.2%. MIC50 for the three tested species was 32, 16, and 8 μg/ml for Trichophyton interdigitale, T. rubrum, and Epidermophyton floccosum isolates, respectively. The corresponding values for nano fluconazole were 8 μg/ml for the three tested species. Conclusion: MIC value for nano-fluconazole was lower than conventional fluconazole in all dermatophytes species tested; therefore, nano-fluconazole could inhibit the growth of dermatophytes better than fluconazole at a lower concentration of the drug.
