AbstractHead lice (Pediculus humanus capitis) are worldwide obligate human ectoparasites, with high implications in pediatrics. In Europe, first-line topical neurotoxic insecticidal therapeutic strategies are being replaced by topical physically acting agents as the first-choice treatment. Safety of the active ingredients and high efficacy in a one-time single-dose treatment with a brief treatment application time are key issues for consumer use and effective compliance. The aim of this study was to assess the in vitro efficacy of a newly developed squalane and dimethicone-based pediculicidal formula, against motile head lice and eggs after 2 and 5 min immersion in the product, as well as its skin tolerance and acceptability under dermatological and pediatric expert control in children with atopic skin. The results indicate that at both time points, 100% mortality rate of head lice crawling stages and late-stage eggs was achieved. The formula was well tolerated and suitable for children with atopic skin from 12 months of age. Showing high in vitro efficacy and good skin acceptability, this solution is presented as a new safe alternative therapy for treatment of head lice infestations.

Permethrin is still the main therapy for human head infestation Pediculosis capitis in several countries, including Indonesia. However, permethrin is not effective for the egg stage. Therefore, alternative therapy from herbs is needed for the treatment of head lice which is effective for both egg and adult stage. The aim of this study was to determine the efficacy of Illicium verum extract and coconut oil formula against eggs of head lice. An in vitro immersion test was applied with four treatment groups (Illicium verum extract and coconut oil formula with four different compositions) as well as a negative control group (distilled water) and a positive control group (permethrin 1%) against eggs of head lice. The eggs of head lice were immersed for 0.5, 1, or 2 min in 1 ml of each solution. Mortality rates of the eggs were recorded after 5 days of incubation. The formula of Illicium verum extract and palm oil with composition 60:40 had the best efficacy with a mortality rate of head lice eggs reached 86,67%, after immersion for 2 minutes. The combination of Illicium verum extract and coconut oil could be an alternative ovicide, but this formula requires precise composition which can be applied for Pediculus humanus capitis.

Korean red ginseng (KRG) is a traditional herbal medicine used to prevent several geriatric diseases due to its therapeutic effects on metabolic disorder, including type 2 diabetes and fatty liver disease. In this study, we investigated the effects of KRG on the progression of nonalcoholic steatohepatitis (NASH) in mice. NASH was induced by feeding a methionine- and choline-deficient high-fat or high-fat/high-sucrose diet for 6 or 13 weeks, respectively. Each diet group was also orally administered saline (group G0) or KRG extract (100, 200, or 400 mg/kg/day; groups G1, G2, and G4, respectively). KRG showed anti-inflammatory and antifibrogenic effects in the diet-induced NASH models. Furthermore, the expression levels of lipid metabolism-related genes were markedly decreased with KRG treatment in both diet-induced NASH groups. We next confirmed the expression levels of FABP4 in the liver and its ability to regulate inflammation and/or oxidative stress. We observed decreased levels of FABP4 mRNA and protein in the KRG-treated groups indicating that KRG affects the pathogenesis of NASH-related inflammatory responses by modulating FABP4 expression. Results of in vitro experiments showed similar patterns in cells treated with KRG, indicating that KRG treatment regulates the expression of FABP4 and subsequently reduces NASH related inflammation. Our findings suggest a novel role of KRG in NASH-related inflammatory responses via modulation of FABP4 expression in the liver. KRG may be a safe alternative therapy to prevent NASH progression.

Pediculosis is a disease caused by Pediculus humanus capitis de Geer or often called head lice which is an obligate ectoparasite in the human head. The prevalence of pediculosis is quite high and there are reports of resistance and negative side effects regarding the use of synthetic pediculosides trigger research and development of vegetable pediculosides. This study aims to examine the effectiveness of the formula of pediculoside with active ingredients of essential oils on head lice mortality in vitro. The study was conducted by testing 3 formulas with variations in the composition of essential oils made from cassava oil, fennel oil, lemon oil, water and vegetable glycerine. Comparison of the ingredients in formula A is 10%, 10%, 5%, 50% and 20%; formula B is 5%, 15%, 5%, 50% and 20%; while formula C is 15%, 5%, 5%, 50% and 20%. The test method is an experiment with a completely randomized design. The test is done by placing 10 adult head lice on filter paper which has been saturated with a formula made in a petri dish. Mortality of head lice is observed based on time. Test results data will be compared with negative controls and positive controls in the form of testing using permethrin-active pediculoside drugs. The results showed that the pediculoside formula A, B and C had a high mortality rate which caused 100% of the deaths of head lice tested in less than 5 minutes. Statistically there is a significance to the results of testing formulas A, B, and C when compared to controls. Based on the results of multiple statistical statistics, it was found that formula C was the most effective as a pediculoside formula

Allicin and ajoene are active compounds in garlic which have proven to be of benefit as antifungal. Meanwhile, the content of oleic acid and triglycerides from the custard apple seeds extract showed anti-fungal activity in vitro. This study aimed to obtain a preparation of creambath combination of garlic extract and custard apple seeds extract which have anti-dandruff and anti head lice activity. Garlic extract was obtained by adding phosphate buffer with freeze-dry method, while custard apple seeds extract was obtained from maceration using petroleum ether. Garlic extract provides an anti-dandruff effect with a minimum inhibitory concentration (MIC) of 6.25 mg/mL and the smallest custard apple seeds extract (LD 100%, 3 hours) which is 3.13 mg/mL can provide anti head lice effect. Variations in the concentration of the combination of garlic extract and custard apple seeds extract used in creambath preparations were (6.25 mg/mL and 3.13 mg/mL), (12.5 mg/mL and 6.25 mg/mL) and (25 mg/mL and 12.5 mg/mL). The resulting creambath preparations have characteristics that are light green, green tea flavored, homogeneous, semisolid form, o/w cream type, pH 5.85-6.25, viscosity 34,000-72,000 cps with thixotropic pseudoplastic flow properties, average size particle 34.31-57.66 μm, anti-dandruff activity with diameters of inhibitory 9, 12, and 16 mm in 72 hours incubation time and LD 100% hair lice activity in 157, 133 and 105 minutes.

SUMMARYHead lice (Pediculus humanus capitis) infestations are a public health concern. The insecticidal properties of the Australian native plantKunzea ambigua(commonly known as tick bush) have been documented. In this study, we tested activity of kunzea oil (KO) against head lice throughin vitrobioassays. Head lice were exposed to filter paper treated with either KO, as either a 5 or 100% oil, or commercial formulations containing either permethrin or tea tree oil (TTO) for 120 min. Head lice exposure to KO, both as a 5 and 100% solution oil, resulted in 100% mortality within 120 min with a mean survival times of 17·1 and 34·8 min, respectively. There was no significant difference between the mean mortality of head lice exposed to 5% KO (17·1 ± 1·0; 95% CI: 115·2–19·0) and 5% TTO (21·2 ± 1·9; 95% CI: 17·4–25·1). This study revealed, for the first time, that KO holds great potential as an effective alternative to current active ingredients contained within commercial pediculicide formulations.

Introduction. The emergence of multidrug-resistant Salmonella Typhimurium strains has increased the need for safe, alternative therapies from natural sources with antibacterial properties. Hypothesis/Gap Statement. There are no published data regarding the use of chitosan propolis nanocomposite (CPNP) either alone or in combination with antibiotics as antimicrobials against S. Typhimurium, especially in Egypt. Aim. This study evaluated the antibacterial activities of five antimicrobials [apramycin, propolis, chitosan nanoparticles (CNPs), chitosan propolis nanocomposite (CPNP) and CPNP +apramycin] against ten virulent and multidrug-resistant (MDR) S. Typhimurium field strains recovered from diarrheic rabbits through in vitro and in vivo study. Methodology. The expression levels of three virulence genes of S. Typhimurium strains were determined by quantitative reverse-transcription PCR (RT-qPCR) after exposure to sub-inhibitory concentrations of apramycin, propolis, CNPs, CPNP alone, and CPNP +apramycin. Additionally, 90 New Zealand rabbits were divided into control and experimentally S. Typhimurium-infected groups. The infected rabbits were orally administered saline solution (infected–untreated); 10 mg apramycin/kg (infected–apramycin-treated); 50 mg propolis/kg (infected–propolis-treated); 15 mg CPNP/kg (infected–CPNP-treated) and 15 mg CPNP +10 mg apramycin/kg (infected–CPNP +apramycin-treated) for 5 days. Results. The RT-qPCR analysis revealed different degrees of downregulation of all screened genes. Furthermore, the treatment of infected rabbits with CPNP or CPNP +apramycin significantly improved performance parameters, and total bacterial and Salmonella species counts, while also modulating both oxidative stress and altered liver and kidney parameters. Conclusion. This work demonstrates the use of CPNP alone or in combination with apramycin in the treatment of S. Typhimurium in rabbits.
