The College of Pharmacy at University of Basrah  held a seminar entitled (Preparation and diagnosis of new di-methylsiloxane derivatives and evaluation of their biological and applied efficacy) with the participation of researchers and specialists.This seminar included a lecture given by researcher Reem Mohsen Khalaf about a study conducted to manufacture noval derivatives of dimethylsiloxane, polyvinylpyrrolidone and phenyl trimethylsilane monomer. This study showed the conduct of testing compounds as antibacterial activity (50-5000 micrograms / ml) using some strains of bacteria, E and Coli, klebsiella, S. Aureus, and P. Aeruginosa. The prepared compounds showed anti-bacterial power at a high concentration compared with povidone iodine as a control and compared to it for its known effectiveness against bacteria. The workshop aimed to demonstrate the importance of dimethylsiloxane polymers in medical applications such as DMS-Zinc complex (PZ), polyvinylpyrrolidone (PVB1), and Polyvinylpyrrolidone-Benzaldehyde-VinylTylethylSylane (PVB2) and tested it on standard New Zealand whiteboard curing and curing time as well as curing the New Zealand whiteboard. Removal of scars resulting from previous wounds. The formula is biocompatible, no irritation, hypoallergenic and no edema when applied to New Zealand rabbits.
