Intestinal metaplasija (IM) is not a common founding. It can be found in less than 5% of people infected with Helicobacter pilory. But Patients with a history of prolonged gastritis and intestinal metaplasia have a 6-fold increase in their risk of developing gastric cancer. The risk is especially high if the intestinal metaplasia is type-3.
What is ozone? Ozone, or O3, is a gas containing three oxygen atoms. Ozone is an unstable chemical that is highly reactive with other gases in the air. Ozone at ground level is unhealthy and is a component of smog. Ozone found high up in the atmosphere, called stratospheric ozone, protects us by shielding us from harmful ultraviolet (UV) light.
Schematic representation of the photochemical ozone formation and destruction. Ozone is a gas found in the atmosphere consisting of three oxygen atoms: O 3. Ozone is formed in the atmosphere when energetic ultraviolet (UV) radiation dissociates molecules of oxygen, O 2, into separate oxygen atoms. Free oxygen atoms can recombine to form oxygen molecules but if a free oxygen atom collides with an oxygen molecule, it joins up, forming ozone.
