    This study aimed to investigate the effects of blood glucose control and the kidneys' functions, depending on fasting, in the streptozotocin-induced diabetes model in rats via TNF-α, NLRP-3, TGF-β1 and VCAM-1 mRNA expression in the present study. 32 Wistar albino rats were allocated randomly into four main groups; H (Healthy, n = 6), HF (Healthy fasting, n = 6), D (Diabetes, n = 10), DF (Diabetes and fasting, n = 10). Blood glucose and HbA1c levels significantly increased in the D group compared to the healthy ones (p < 0.05). However, the fasting period significantly improved blood glucose and HbA1c levels 14 days after STZ induced diabetes in rats compared to the D group. Similar findings we obtained for serum (BUN-creatinine) and urine samples (creatinine and urea levels). STZ induced high glucose levels significantly up-regulated TNF-α, NLRP-3, TGF-β1 and VCAM-1 mRNA expression and fasting significantly decreased these parameters when compared to diabetic rats. Histopathological staining also demonstrated the protective effects of fasting on diabetic kidney tissue. In conclusion, intermittent fasting regulated blood glucose level as well as decreasing harmful effects of diabetes on kidney tissue. The fasting period significantly decreased the hyperglycemia-related inflammatory cytokine damage on kidneys and also reduced apoptosis in favor of living organisms.

    Protective effect of luteolin on acute lung injury in a rat model of sepsis
    (2021-01-01) Celebi D.; Aydin P.; Cinar I.; Kutlu Z.; Calik I.; Halici Z.; Bilici D.; Bayraktutan Z.
    We investigated the effects of luteolin (LUT) treatment on acute lung injury caused by cecal ligation and puncture (CLP) induced septic rats. We also investigated the relation between LUT and the cytokines, interleukin-10 (IL-10) and tumor necrosis factor-α (TNF-α). LUT was administered 1 h after CLP surgery. Administration of LUT reduced the glutathione level and superoxide dismutase activity in rat lung tissues. We also found significant reduction of malondialdehyde following LUT treatment. LUT administration also reduced TNF-α and IL-10 mRNA expression in lung tissue. Histopathologic investigation of lung tissue supported our biochemical and molecular findings. Administration of LUT ameliorated lung injury in CLP induced septic rats owing to its antioxidant and anti-inflammatory properties.
