[Blood enzyme activities in men and women with certain diseases]

The activities of glutamic-pyruvic transaminase (GPT) and catalase are increased by 42 to 283% in patients with neurodermatitis, eczema, and psoriasis, whereas the activities of glutamic-oxaloacetic transaminase, alkaline phosphatase, and cholinesterase are unchanged. In women with neurodermatitis and psoriasis the level of GPT is by 24-28% lower than in men. In psoriasis catalase activity in women is by 50% higher than in men. Hence, the activities of some enzymes in disease are related to patients' sex. Blood serum catalase measurements are diagnostically valuable in skin diseases.
