Gastric Ulcer Evaluation and Oxidative Stress

Check if the same lab product or an alternative is used in the 5 most similar protocols
All animal groups were subjected to determinate gastric ulcer indices; lesion counts, total acidity, and gastric volume. Oxidative stress markers; malondialdehyde (MDA) (Buege and Aust, 1978 (link)), superoxide dismutase (SOD) (Nishikimi et al., 1972 (link)) and glutathione (GSH) (Moron et al., 1979 (link)) were estimated in gastric tissue. Certain marker enzymes; succinate dehydrogenase (SDH) (mitochondrial marker) (Rice and Shelton (1957) (link), lactate dehydrogenase (LDH) (cytoplasm marker) (Babson and Babson, 1973 (link)), gluose-6-phosphatase (G-6-Pase) (microsomal marker) (Swanson, 1955 ), acid phosphatase (AP) (lysosomal marker) (De Duve and Wattiaux, 1956 (link)) and 5′- nucleotidase (5′NT) (plasma membrane marker) (Bodansky and Schwartz, 1963 (link)) were also carried out in gastric tissue. Inflammatory index were estimated by ELISA technique; interleukin-10 (IL-10) (Abcam, ab100765, Cambridge, USA), intracellular adhesion molecule-1 (ICAM-1) (Abcam, ab100763, Cambridge, USA), and tumor necrosis factor alpha (TNF-α) (Abcam, ab100785, Cambridge, USA) were also evaluated in gastric tissue.

Oxidative and Inflammatory Markers in Heart Tissues

Check if the same lab product or an alternative is used in the 5 most similar protocols
Homogenization of heart tissues was carried out in a 10-fold volume of ice-cooled phosphate-buffered saline (PBS) (ice-cooled, pH 7.4). Following centrifugation at 10,000× g for 20 min and 4 °C, the supernatant was then collected for analysis of oxidative and inflammatory markers. ELISA kits were used in the assessment of the hearts’ content of malondialdehyde (MDA), reduced glutathione (GSH), enzymatic activities of superoxide dismutase (SOD), catalase (CAT) (Cat. No. MD 2529, GR 2511, SD 2521, and CA 2517, Biodiagnostic, Giza, Egypt, respectively), and protein carbonyl, interlukin-6 (IL-6), and tumor necrosis factor α (TNF-α) (Cat. No. ab238536, ab234570, and ab100785, Abcam, Cambridge, UK, respectively).
Nuclear fractions of tissue homogenates were obtained using NE-PER nuclear and cytoplasmic extraction kit (Cat. No. 78833, Thermo Fisher Scientific, Waltham, MA, USA). Protein content of the nuclear extracts was determined, and a volume equivalent to 80 μg was employed in the assessment of the DNA-binding activity of NF-kB p65 using NF-κB p65 ELISA Kit (Cat. No. ab133112, Abcam, Cambridge, UK). Results are expressed as fold change of control.

Levels of inflammatory factors and pulmonary surfactant in serum of rats were determined with Enzyme-linked immunosorbent (ELISA) assays. The rats (Abcam, ab100785) tumor necrosis factor (TNF)-α ELISA kit, rats (Abcam, ab100768) interleukin (IL)-1β ELISA kit, rats (Abcam, ab213909) IL-18 ELISA kit, rats (Yubo company, Shanghai, China) surfactant protein A (SP-A) ELISA kit and rats (Yubo company, Shanghai, China) surfactant protein A (SP-D) ELISA kit were used to determine levels of TNF-α, IL-1β, IL-18, SP-A and SP-D in the serum of rats. In addition, levels of inducible nitric oxide synthase (iNOS) in serum were detected with commercial kits (Lanpai company, Shanghai, China). All the assays were performed according to the manufacturers’ operating instructions.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
