Descriere<br />

RO<br />

STEM cells of hair follicles. It is biocompatible and treats<br />

open wounds and burns.<br />

The powder has a high styptic, antiseptic, healing and<br />

regenerative capacity, because uses as support<br />

pharmaceutical fibrin mixed with sulphamide, lactose and<br />

calcium carbonate. After that coloidal silver (99.95% and<br />

10...80 nm particles size) is pulverized at a concentration of<br />

10 to 20 ppm.<br />

Invenţia se referă la o pudră funcţionalizată cu argint<br />

coloidal, pentru stimularea si proliferarea celulelor STEM a<br />

foliculilor pilosi. Aceasta este biocompatibila si tratează<br />

ranile deschise şi arsurile.<br />

Pudra are capacitate mare hemostatică, cicatrizantă şi<br />

regenerativă, deoarece este alcătuită din: fibrină amestecată<br />

cu sulfamidă, lactoză şi carbonat de calciu. După amestecul<br />

acestora argintul (99,95%, dimensiunea particulelor 10...80<br />

nm) este pulverizat într-o concentraţie de 10...20 ppm.<br />

Patent no. Pending<br />

The possibility to obtain different amphiphilic polymers with<br />

potential applications as drug delivery systems is presented. The<br />

polymers were synthesized by living radical polymerization<br />

using a polysiloxane macroinitiator containing cloro-benzil<br />

groups in the macromolecular side chain. Poly (dimethyl<br />

acrylic amides) sequences are able to react in the presence of<br />

thermal stimuli. Thus, depending on the existing conditions in<br />

Description the external environment, these sequences may adopt a linear or<br />

EN entangled conformation. If we associate these conformations<br />

with micelles structures, this could lead to an<br />

aggregation/disaggregation phenomenon, under thermal<br />

stimulation. Polymers were characterized by 1H-NMR<br />

spectroscopy, thermal gravimetric analysis and differential<br />

scanning calorimetry. The conformational changes were<br />

revealed by rheological tests studying the variation of loss and<br />

storage moduli versus temperature.<br />
