The existence of labial SMAS — Anatomical, imaging and histological study

Cutaneous insertion of the facial mimic muscles concerns, at different levels, the superficial fascia of that region. A superficial musculoaponeurotic system is described at face level that facilitates skin insertion of the facial expression muscles through the superficial fascia that acquires particular functional aspects in each region of the face. The existence of a musculofascial system is seen controversial among anatomists, which is why the purpose of this study is to establish its existence at the oral region. The material used in our study consists of twenty-four dissected hemifacies, wherefrom we have recorded images using an operator microscope. Tissue samples have been taken from anatomical specimens examining them by usual staining methods. In parallel, fifteen patients have been investigated with imaging methods (MRI and CT). The results prove the existence of an oral musculoaponeurotic system with a particular organization, similar in the upper and lower part. The superficial fascia disappears into the free margin of the upper and lower lips, as we are emphasizing in the images taken from this level. These findings explain the functional anatomy of this region, but they also form the background of the modern oral plastic surgery.

The decontamination of aqueous solutions with toxic content deriving from oral biomucoadhesive tablets for protecting the quality of waters

The formulation and the preparation of new pharmaceutical forms conducted by the great companies can represent a danger for the environment because of their toxic potential. The study suggests a new method for the treatment of the wastewater from the pharmaceutical industry that uses polyethylene glycols, sodium carboxymethyl cellulose as the forming matrix polymers and nitrites as toxic waste. The novelty of the method consists in the high capacity of withholding the toxic element in spite of the fact that the jellification potential of the polymers used in compression; this makes the removal of nitrates from the treatment column more difficult. The polluting element considered in this study is the nitrate anion present in the oral biomucoadhesive tablets and the resin used for withholding the toxic element is the DowexTM NSR-1. Thus, after the pharmaceutical form has been introduced in distilled water and the resulting solution was filtered using the Dowex resin, a chemical trial report of the water was made and all the parameters studied were below the admissible limits of the regulations in force.
