The evaluation of sterile solutions of Ilwensisaponin A and C from Verbascum pterocalycinum var. mutense Hub.-Mor. on antiviral, antinociceptive and anti-inflammatory activities
Antiviral, antinociceptive and anti-inflammatory activities of the 1% sterile solutions of Ilwensisaponin A and C isolated from the methanolic extract of the flowers of Verbascum pterocalycinum var. mutense Hub.-Mor. were investigated. Antiviral activities of sterile solutions were evaluated against Bovine Herpes Virus Type-1 (BHV-1) (Cooper strain). Both solutions showed cytotoxic effects. However, none of the sterile solutions showed antiviral activity with CPE values. Anti-inflammatory and antinociceptive response were obtained at doses of 100 mg/kg. The results of the evaluation of the anti-inflammatory activities induced by carrageenan showed that these sterile solutions possess active constituents and diminish cyclooxygenase activitiy. In addition, antinociceptive activities using p-benzoquinone-induced writhing model in mice of tested solutions were found to show notable activity in statistical analysis without inducing any apparent acute toxicity as well as gastric damage. To the best of our knowledge, this study is the first investigation of antiviral, anti-inflammatory and antinociceptive activities of sterile solutions of Ilwensisaponin A and C isolated from Verbascum pterocalycinum var. mutense Hub.-Mor. growing in Turkey.

Olfactory dysfunction and coronavirus disease 2019 severity: a prospective cohort study.
© 2021 Cambridge University Press. All rights reserved.Objective. The primary goal of this study was to evaluate the association between olfactory dysfunction or taste impairment olfactory dysfunction and disease severity and radiological findings in coronavirus disease-2019. The secondary goal was to assess the prevalence, severity and course of olfactory dysfunction or taste impairment in patients with coronavirus disease 2019. Method. This prospective observational cohort study evaluated patients hospitalised with coronavirus disease 2019 between April 1 and 1 May 2020. olfactory dysfunction and taste impairment were evaluated by two questionnaires. Chest computed tomography findings and coronavirus disease 2019 severity were assessed. Results. Among 133 patients, 23.3 per cent and 30.8 per cent experienced olfactory dysfunction and taste impairment, respectively, and 17.2 per cent experienced both. The mean age was 56.03 years, and 64.7 per cent were male and 35.3 per cent were female. No statistically significant association was found between olfactory dysfunction (p = 0.706) and taste impairment (p = 0.35) with either disease severity or chest computed tomography grading. Conclusion. Olfactory dysfunction or taste impairment does not have prognostic importance in patients with coronavirus disease 2019
The evaluation of sterile solutions of Ilwensisaponin A and C from Verbascum pterocalycinum var. mutense Hub.-Mor. on antiviral, antinociceptive and anti-inflammatory activities
Antiviral, antinociceptive and anti-inflammatory activities of the 1\%
sterile solutions of Ilwensisaponin A and C isolated from the methanolic
extract of the flowers of Verbascum pterocalycinum var. mutense
Hub.-Mor. were investigated. Antiviral activities of sterile solutions
were evaluated against Bovine Herpes Virus Type-1 (BHV-1) (Cooper
strain). Both solutions showed cytotoxic effects. However, none of the
sterile solutions showed antiviral activity with CPE values.
Anti-inflammatory and antinociceptive response were obtained at doses of
100 mg/kg. The results of the evaluation of the anti-inflammatory
activities induced by carrageenan showed that these sterile solutions
possess active constituents and diminish cyclooxygenase activitiy. In
addition, antinociceptive activities using p-benzoquinone-induced
writhing model in mice of tested solutions were found to show notable
activity in statistical analysis without inducing any apparent acute
toxicity as well as gastric damage. To the best of our knowledge, this
study is the first investigation of antiviral, anti-inflammatory and
antinociceptive activities of sterile solutions of Ilwensisaponin A and

Development of Microsponges for Topical Delivery of Mupirocin
The goal of the present study was to develop and evaluate microsponge-based topical delivery system of mupirocin for sustained release and enhanced drug deposition in the skin. Microsponges containing mupirocin were prepared by an emulsion solvent diffusion method. The effect of formulation and process variables such as internal phase volume and stirring speed on the physical characteristics of microsponges were examined on optimized drug/polymer ratio by 32 factorial design. The optimized microsponges were incorporated into an emulgel base. In vitro drug release, ex vivo drug deposition, and in vivo antibacterial activity of mupirocin-loaded formulations were studied. Developed microsponges were spherical and porous, and there was no interaction between drug and polymer molecules. Emulgels containing microsponges showed desired physical properties. Drug release through cellulose dialysis membrane showed diffusion-controlled release pattern and drug deposition studies using rat abdominal skin exhibited significant retention of active in skin from microsponge-based formulations by 24 h. The optimized formulations were stable and nonirritant to skin as demonstrated by Draize patch test. Microsponges-based emulgel formulations showed prolonged efficacy in mouse surgical wound model infected with S. aureus. Mupirocin was stable in topical emulgel formulations and showed enhanced retention in the skin indicating better potential of the delivery system for treatment of primary and secondary skin infections, such as impetigo, eczema, and atopic dermatitis
