The Procoagulant Activity of Emoxilane®: A New Appealing Therapeutic Use in Epistaxis of the Combination of Sodium Hyaluronate, Silver Salt, α-tocopherol and D-panthenol

Epistaxis is one of the most frequent hemorrhages resulting from local or systemic factors. Its management without hospitalization has prompted an interest in locally applied hemostatic agents. Generally, the therapy approaches involve sprays or creams acting as a physical barrier, even used as tampons or gauze. In this study, we have investigated the activity of Emoxilane®, a combination of sodium hyaluronate, silver salt, α-tocopherol acetate and D-panthenol, which is known to be able to separately act in a different biological manner. Our in vitro results, obtained on endothelial and nasal epithelial cells, have shown that the association of these molecules presented a notable antioxidant activity mainly due to the α-tocopherol and D-panthenol and a significant antimicrobial role thanks to the silver compound. Moreover, remarkable hemostatic activity was found by evaluating plasmin inhibition attributable to the sodium hyaluronate. Interestingly, on human plasma, we have confirmed that Emoxilane® strongly induced the increase of thrombin levels. These data suggest that the use of this association could represent an appealing pharmacological approach to actively induce hemostasis during epistaxis. Our future perspective will aim to the creation of a formulation for an easy topical application in the nose which is able to contrast the bleeding.

A Novel Tetranuclear Silver Compound with bis(3,5-dimethylpyrazol-1-yl)acetate: a Simple Synthesis Yielding Complex Crystal Structure

A novel tetranuclear silver coordination compound with the formula [Ag4(bdmpza)4]·10H2O (bdmpza = bis(3,5-dimethylpyrazol-1-yl)acetate) was synthesized by a reaction between an aqueous solution of silver nitrate and an aqueous solution prepared by bis(3,5-dimethylpyrazol-1-yl)acetic acid and potassium hydroxide (1:1 molar ratio). The obtained compound was characterized by elemental analysis, coupled thermogravimetric–mass spectrometry analysis, vibrational IR spectroscopy, and its crystal structure was determined by single-crystal X-ray diffraction method. Furthermore, the obtained crystal structure was additionally evaluated by Hirshfeld surface analysis.

Uses of comet assay techniques to evaluate the effect of green synthesis of nanoparticles of Origanum Vulgare plant for the treatment of lymphocyte cells damage in diabetic patients

Background: Silver nanoparticles are characterized with a high production techniques, in this study nanoparticles were manufactured using Origanum vulgare water extract and AgnO3. Objective: Experimental factors such as morphology and optical properties of nanoparticles were studied through specific assay such as morphology, spectroscopy of UV rays (UV-Visible), FE-SEM, FT-IR, and Atomic Force Analysis (AFM). Materials and Methods: showed that the spherical nanoparticles were found using TEM, with an average particle size distribution of 44.2 ± 88.1 nm with more than one active plant substance used within the Nano silver compound. In addition, the green nanoparticles have a response in treatment of damage in DNA based on the dose and structure of the nanoparticle in the lymphocytes of the patient with diabetic cells. Results &conclusion: These nanoparticles can be considered healthy and can be used without harming healthy parts. The DNA rate in lymphocyte cells was calculated for patients with diabetes using the comet technique. The results showed that the rate of destruction of lymphocytes was reduced for diabetic patient.
