38. Effect of topical ozonetherapy on gingival wound healing in pigs: histological and immuno-histochemical analysis
Abstract In this study, the effects of ozonetherapy on secondary wound healing were evaluated histologically and immuno-histochemically. Material and Methods: 8 healthy pigs were used in this study. Six wounds with 10 mm in diameter were created through the punch technique on the palatinal gingiva of each pig. Ozone gas was applied on only 3 wounds (test gro

39. Ozone in polycyclic aromatic hydrocarbon degradation
Abstract Among energy sources from food, corn is a cereal with significant nutritional characteristics. However, during preprocessing, corn is subject to contamination by polycyclic aromatic hydrocarbons, which are considered carcinogenic, and gas ozone can be used as an alternative for decontamination. This study aims to evaluate the effect of ozonation on

46. Medical ozone therapy reduces oxidative stress and testicular damage in an experimental model of testicular torsion in rats
ABSTRACT Objective: Testicular torsion (TT) refers to rotation of the testis and twisting of the spermatic cord. TT results in ischemia-reperfusion (I/R) injury involving increased oxidative stress, inflammation and apoptosis, and can even lead to infertility. The aim of this study was to investigate the effect of ozone therapy on testicular damage due to I
