Diabetes mellitus (DM) is a chronic metabolic disorder with an increasing global prevalence that leads to significant morbidity and mortality. The liver plays a vital role in glycemic regulation in physiological and pathological conditions such as DM. Free radical formation and inhibition of antioxidant defense systems play a role in the liver damage pathogenesis in diabetic patients The antioxidant, anti-diabetic, anti-inflammatory, and radical scavenging properties of crocin are known. This study was designed to determine the possible protective effects of crocin against liver tissue damage in pinealectomized diabetic rats. Sixty rats were divided into six groups: Control, Sham+streptozotocin (STZ), Pinealectomy (PINX), PINX+STZ, PINX+Crocin, and PINX+STZ+Crocin. PNX procedure was carried out on the first day of the experiment. Intraperitoneal (i.p.) injection of 50 mg/kg STZ was performed on the 30th day of the experiment to induce DM. Crocin (50 mg/kg; i.p.) was applied for 15 days after the pinealectomy procedure and induction of DM. Crocin decreased the markers (alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), interleukin-1β (IL-1β), and malondialdehyde (MDA)) of liver damage and increased antioxidant enzyme levels and tissue total antioxidant status. Histological results showed that the administration of crocin exhibited a protective effect against liver damage caused by STZ. These results indicate that crocin evidence protection against liver injury caused by STZ.
