Effects of constant light exposure on blood biochemical parameters in rats and the potential for melatonin correction

Abstract

Abstract. The study investigates the effects of constant light exposure on biochemical parameters in rats and the potential corrective role of melatonin. Results showed significant increases in glucose, triglycerides, and cholesterol levels, and a slight decrease in total protein under influence of 7 days constant light. Melatonin administration at dose of 5 mg/kg along with constant light exposure during 7 days mitigated these effects, reducing glucose, triglycerides and cholesterol and restoring total protein levels. These findings highlight melatonin's potential as a therapeutic agent for light-induced metabolic disruptions.
