Background:
The role of free radicals and hydrogen peroxides in the metabolism and toxicity of alcohol is supported by many studies, therefore, many autors have tried to use the enzymes, metabolizing highly reactive chemical compounds as biological markers of alcoholism.
Methods:
Erythrocyte antioxidant enzymes were measured in 37 male patients with alcohol dependence syndrome, without severe liver disease, aged between 18 and 59 years, with different duration (years) of alcohol abuse.
Results:
Superoxide dismutase (SOD) activity was statistically significantly increased in alcoholics. Glutathione peroxidase (GPX) activity has shown no significant difference in alcoholics compared to the control group. Catalase (CAT) activity was significantly decreased in alcoholics. Specific activity of CAT was positively correlated with the duration of alcohol abuse (years).
Conclusions:
Catalase activity has shown statistically significant decrease in patients with alcohol dependence syndrom. (Tab. 3, Fig. 4, Ref: 31.)

Factors Affecting Erythropoiesis
Several factors influence the erythrocyte production rate, with tissue oxygen level being among the most critical. Intense exercise or high altitudes can cause tissue hypoxia, which triggers the kidneys to release more erythropoietin (EPO) into the bloodstream.

Disorders of Erythrocytes
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.

Oxidation of Phenols to Quinones
o-hydroxy phenols are oxidized to o-quinones and p-hydroxy phenols to p-quinones. Such redox reactions involve the transfer of two electrons and two protons. The reversible redox property is crucial in...
