Protective Effects of Fuziline on Dobutamine-Induced Heart Damage in Mice.

INTRODUCTION: Fuziline is one of the many antioxidants currently being tested to treat cardiac damage. In our study, histopathological and biochemical effects of fuziline were investigated in mice with dobutamine-induced heart damage in vitro. METHODS: Thirty-two adult male BALB/c mice, average weight of 18-20 g, were randomly divided into four groups - Group 1 (sham, n=8), Group 2 (control, dobutamine, n=8), Group 3 (treatment 1, dobutamine + fuziline, n=8), and Group 4 (treatment 2, fuziline, n=8). Biochemical parameters and total antioxidant status (TAS), total oxidant status (TOS), and oxidative stress index (OSI) values were measured. Interleukin 1 beta (IL-1ß), NLR family, pyrin domain containing protein 3 (NLRP3), 8-hydroxy-deoxyguanosine (8-OHDG), gasdermin D (GSDMD), and galectin 3 (GAL-3) levels were analyzed by enzyme-linked immunosorbent assay method, and histopathological examination of heart tissues was performed. RESULTS: When dobutamine + fuziline and fuziline groups were compared, troponin-I (P<0.05), NLRP3 (P<0.001), GSDMD (P<0.001), 8-OHDG (P<0.001), IL-1ß (P<0.001), and GAL-3 (P<0.05) were found to be statistically significant. TOS level was the highest in the dobutamine group (P<0.001) and TAS level was the highest in the fuziline group (P<0.001). OSI level was statistically significant between the groups (P<0.001). In histopathological examination, focal necrosis areas were smaller in the dobutamine + fuziline group than in the dobutamine group, and cardiac myocytes were better preserved. CONCLUSION: Fuziline markedly reduced cardiac damage and pyroptosis in mice with dobutamine-induced heart damage by lowering the levels of GSDMD, 8-OHDG, IL-1ß, and GAL-3. It also prevented necrosis of cardiac myocytes in histopathological evaluation.

Cardioprotective Effect of Pistacia vera L. (Green Pistachio) Hull Extract in Wistar Albino Rats with Doxorubicin-Induced Cardiac Damage.

BACKGROUND: Pistacia vera L. (green pistachio) has been shown to increase antioxidant capacity and protect against cardiovascular diseases and cancer. This study investigated the protective effect of the Pistacia vera L. hull in rats with experimental cardiac damage induced by doxorubicin. METHODS: Sixty adult Wistar albino rats were randomly divided into 5 groups (n = 12). Sham, doxorubicin, doxorubicin + Pistacia vera L. extract 50 mg/kg, doxorubicin + Pistacia vera L. extract 100 mg/kg, and Pistacia vera L. extract 100 mg/kg. Biochemistry parameters, total antioxidant status, total oxidant status, oxidative stress index, 8-hydroxydeoxy guanosine, and caspase 3/7 values were measured in serum samples. Excised heart tissues were examined histopathologically. RESULTS: The groups were statistically significantly different in 8hydroxydeoxy guanosine, caspase 3/7, total antioxidant status, total oxidant status, oxidative stress index, and basal biochemical parameter values (P <.05, P <.001). In group II, 8-hydroxydeoxy guanosine, caspase 3/7, and total oxidant status values increased while the total antioxidant status value decreased (P <.001). In the treatment groups (group III and group IV), 8-hydroxydeoxy guano sine and caspase 3/7 values decreased compared to group II (P < .001). While total oxidant status and oxidative stress index values decreased in the treatment groups, total antioxidant status values increased (P <.001). The histopathological examination of the heart revealed fewer areas of focal necrosis in the treatment groups compared to group II. CONCLUSION: In this study, the cardioprotective effect of Pistacia vera L. hull extract was investigated in vivo. It was shown that Pistacia vera L. hull extract reduced apoptosis and deoxyribonucleic acid damage in the face of cardiac damage and had antioxidant activity. Future studies will increase our knowledge on this subject.

Biochemical parameters and total antioxidant status (TAS), total oxidant status (TOS), and oxidative stress index (OSI) values were measured. Interleukin 1 beta (IL-1β), NLR family, pyrin domain containing protein 3 (NLRP3), 8-hydroxy-deoxyguanosine (8-OHDG), gasdermin D (GSDMD), and galectin 3 (GAL-3) levels were analyzed by enzyme-linked immunosorbent assay method, and histopathological examination of heart tissues was performed.

It also prevented necrosis of cardiac myocytes in histopathological evaluation.

Soluble ST2 as a Potential Biomarker in Pericardial Fluid of Coronary Artery Patients

Abstract Introduction: The growth Stimulation expressed gene 2 (ST2) (or interleukin 1 receptor-like 1, also known as IL1RL1) is considered a biomarker of poor prognosis in cardiovascular diseases. The aims of this study are to investigate ST2 in the pericardial fluid (PF) of coronary artery disease patients and to contribute to the understanding of the pathophysiology of coronary artery disease. Methods: 40 patients (blood plasma and PF) who underwent coronary artery bypass surgery and 40 controls (blood plasma only) were included in this study. Soluble ST2 (sST2) level was determined by enzyme-linked ımmunosorbent assay method in plasma and PF, and sST2 gene expression was determined by quantitative real-time polymerase chain reaction (QRT-PCR) method. Results: The sST2 level was found to be 44.89 ng/ml and 390.357 ng/ml in the control and patient groups' plasma, and 223.992 ng/ml in the PF of the patient group. An increase in sST2 level was detected in the patient group compared to the control group (P<0.001). The sST2 expression in plasma was higher in the patient group than in the control group. Additionally, sST2 was more expressed in the plasma of the patient group than PF (P<0.001). Conclusion: The fact that sST2 was detected for the first time in a high level in PF showed that this biomarker was closely related with the heart and strengthened its potential to be used as a biomarker. Therefore, sST2 can contribute to the understanding of the pathophysiology of coronary artery disease.
