Various stresses derived from both internal and external oxidative environments lead to the excessive production of reactive oxygen species (ROS) causing progressive intracellular oxidative damage and ultimately cell death. The objective of this study was to evaluate the protective effects of Citrus junos Tanaka peel extract (CE) against oxidative-stress induced the apoptosis of lung cells and the associated mechanisms of action using in vitro and in vivo models. The protective effect of CE was evaluated in vitro in NCI-H460 human lung cells exposed to pro-oxidant H2O2. The preventive effect of CE (200 mg/kg/day, 10 days) against pulmonary injuries following acrolein inhalation (10 ppm for 12 h) was investigated using an in vivo mouse model. Herein, we demonstrated the inhibitory effect of CE against the oxidative stress-induced apoptosis of lung cells under a highly oxidative environment. The function of CE is linked with its ability to suppress ROS-dependent, p53-mediated apoptotic signaling. Furthermore, we evaluated the protective role of CE against apoptotic pulmonary injuries associated with the inhalation of acrolein, a ubiquitous and highly oxidizing environmental respiratory pollutant, through the attenuation of oxidative stress. The results indicated that CE exhibits a protective effect against the oxidative stress-induced apoptosis of lung cells in both in vitro and in vivo models.

The present study was carried out to determine the effects of sub-chronic thinner addiction on the oxidant-antioxidant balance and oxidative stress on certain tissues and the possible protective effect of safranal against thinner toxication in rats. Adult male Wistar albino rats were randomly divided into four groups of 10 animals each as follows: control (C), safranal (S), thinner (T) and thinner+safranal (T+S). The control group received 1cc saline by gastric gavage. Safranal was administered to S and T+S groups by using gastric gavage at a dose of 100 mg/kg/day and volume of 0.1 mL/kg/day. Thinner inhalation was applied to T and T+S groups in a container with NaOH tablets twice a day. Levels of malondialdehyde (MDA), reduced glutathione (GSH), nitric oxide (NOx) metabolites, total antioxidant capacity (TAS) and total oxidant capacity (TOS) were determined in liver, lung, brain, kidney and testis tissues of the rats. In the T+S group, it was observed that the MDA levels significantly decreased in all tissues, except the kidney, in comparison to the thinner inhalation group (p = 0.000). When the NOx levels of the T+S group were compared with the levels of the T group, it was concluded that there existed a statistically significant decrease in the NOx levels in alltissues (p = 0.000). In T+S group, it was observed that safranal either eliminated or mitigated oxidative stress that developed in tissues through decreasing MDA and TOS levels and increasing GSH and TAS levels and caused significant decreases in NOX levels in all tissues. As a result, it was determined that safranal, although not uniform for all tissue types, had a protective potential against the damaging effects of oxidative stress caused by sub-chronic thinner inhalation.

Isoniazid and rifampicin are drugs primarily used in antituberculosis treatment. Our aim in this study is to evaluate the effect of caffeic acid phenethyl ester's protective effect on liver function tests and to trace elements in hepatic damage caused by isoniazid and rifampicin on rats. Forty Wistar albino rats were divided into 4 groups. Group 1: Sham, Group 2: caffeic acid phenethyl ester application, Group 3: isoniazid and rifampicin given, Group 4: isoniazid + rifampicin and caffeic acid phenethyl ester application. After 30 days, the rats were sacrificed by taking blood from the heart. Alanine aminotransferase, aspartate aminotransferase, zinc, copper, total antioxidant capacity, total oxidative status, and oxidative stress index levels were evaluated. The rats to which isoniazid + rifampicin+ caffeic acid phenethyl ester were given had less oxidative stress and copper levels (P < 0.001, P = 0.019) but have higher zinc levels (P = 0.001) compared to the isoniazid + rifampicin group. Liver enzyme levels were also lower in rats that were given isoniazid + rifampicin + caffeic acid phenethyl ester (P < 0.001). The results of this study suggested that caffeic acid phenethyl ester influences the levels of trace elements (copper and zinc) that are important for the physiologic mechanisms of organisms, reducing liver damage.
