Food Chemistry, 2014
In this paper the oil from seeds of Amaranthus cruentus L. (AmO) was shown to be an efficient modulator of the physical chemical properties of artificial lipid and rat hepatocyte plasma membranes. AmO improved the membrane stability, their stress resistance and the adsorption of neurotensin to plasma membranes with the distinct biphasic interactions being observed even after adrenalin stress exposure. The analysis of pro-/antioxidant balance in rat blood revealed a mild prooxidant activity after AmO intake, which was accompanied by accumulation of oxidative destruction products in plasma membranes. This prooxidant action of AmO was corroborated in vitro in an adrenalin autooxidation model. On the other hand, the observed improved resistance to adrenalin stress in AmO supplemented rats was associated with an antioxidant response in blood and plasma membrane studies. The AmO effects can be attributed to the modulation of the metabolic pathways involved into oxygen and free radical homeostasis. (D. Mazur), lutsyk@meduniv.lviv.ua (O.D.

Aims: Our earlier studies revealed the cardio-protective effects of oleic acid, a monounsaturated fatty acid, against adrenaline induced myocardial injury. Moreover, it has been found to possess antioxidant properties. Thus, in the present study we have investigated the protective role of oleic acid on adrenaline induced mitochondrial dysfunction in vitro in rat heart mitochondria. Main Methods: Isolated rat cardiac mitochondria was incubated in vitro with adrenalinebitartrate alone and with graded doses of oleic acid. Biomarkers of oxidative stress, mitochondrial Krebs cycle enzymes and respiratory chain enzymes along with mitochondrial morphology, membrane potential as well as intactness were analyzed. Isothermal titration calorimetric studies with pure adrenaline and oleic acid was also carried out.

Effect of prefeeding dehydrated amaranth (A. gangeticus) leaves at 10 and 20% levels on a chemical toxicant, dimethylhydrazine (DMH)-induced free radical stress in rat liver was evaluated. DMH-induced rise in hepatic malondialdehyde (MDA), was diminished by AL. AL intake resulted in a significant increase in hepatic glutathione (GSH). The feeding of AL at 10% level increased the hepatic glucose-6-phosphate dehydrogenase (G-6-PDH) activity, while that at 20% level increased the hepatic glutathione reductase (GSSGR) as well, in addition to G-6-PDH. Amaranth leaves at 10 and 20% levels of feeding diminished the hepatic superoxide dismutase and glutathione peroxidase (GSH-Px) activities. DMH influenced adversely the hepatic antioxidant enzyme activities. Simultaneous administration of DMH and feeding of AL enhanced the DMH-induced decrease in hepatic GSH-Px. DMH enhanced formation of micronuclei was reverted significantly by AL intake. Hence, it was concluded that the consumption of AL ...

The aim of present research was to study the effects of Amaranth oil (AmO) supplementation on aerobic metabolism and heart rate variability (HRV) in type 2 diabetes mellitus patients and in athletes. Several parameters of aerobic metabolism and HRV were assessed. Supplementation with AmO caused mild pro-oxidant activity resulting in improved uptake of oxidative destruction products and modulation of catalase and SOD activity with subsequent development of an antioxidant effect. These findings were very distinct in athletes but less pronounced in diabetics. Redistribution of haemoglobin ligands in athletes indicates involvement of haemoproteins in free radical reactions during AmO supplementation. Improvement in HRV by daily consumption of AmO as observed in both study groups suggested increased production of endogenous oxygen and enhancement of the cardio-respiratory function. The advantage of activation of aerobic metabolism in OS-related disorders resulting in improved self-organization of the living system and hormetic reaction mechanisms are discussed.
The effect of flavonoids on rat heart mitochondrial function
Biomedicine & Pharmacotherapy, 2006
In this study the effects of flavonoids (quercetin and its derivatives as rutin, hyperoside, quercitrin) on the oxidative phosphorylation in rat heart mitochondria were investigated. We found that all investigated flavonoids possessed uncoupling activity. Thus, quercetin, rutin, and quercitrin in dose-dependent manner induced a stimulation of the State 2 respiration rate by 10-110% with pyruvate + malate as substrate. The maximal stimulation of the State 2 respiration rate was obtained at 1.08 ng/ml of quercetin, 15.2 ng/ml of hyperoside and 44.4 ng/ml of rutin. Quercitrin had clearly lower effects. The State 3 respiration rate was also affected by flavonoids. Quercetin (from 1.08 ng/ml), hyperoside (from 10 ng/ml) and rutin (from 60 ng/ml) caused the decrease in State 3 respiration rate by 16-51%. We assume, that partial mitochondrial uncoupling (without affecting the State 3 respiration rate) induced by flavonoids could have a cardioprotective effect, and that mitochondria could be involved in the mechanism of this process.

Background and Aim: Consumption of fatty acids (FA) can alter hepatic energy metabolism and mitochondrial function in the liver. Crocodile oil (CO) is rich in mono-and polyunsaturated FAs, which have natural anti-inflammatory and healing properties. In rat livers, we investigated the effect of CO on mitochondrial function for energy homeostasis. Materials and Methods: Twenty-one male Sprague-Dawley rats were divided into three groups at random. Group 1 rats were given sterile water (RO), Group 2 rats were given CO (3% v/w), and Group 3 rats were given palm oil (PO) (3% v/w). For 7 weeks, rats were given sterile water, CO, and PO orally. The researchers looked at body weight, food intake, liver weight, energy intake, blood lipid profiles, and mitochondria-targeted metabolites in the liver. The liver's histopathology, mitochondrial architecture, and hydrolase domain containing 3 (HDHD3) protein expression in liver mitochondria were studied. Results: Body weight, liver weight, liver index, dietary energy intake, and serum lipid profiles were all unaffected by CO treatment. The CO group consumed significantly less food than the RO group. The CO group also had significantly higher levels of oxaloacetate and malate than the PO group. CO treatment significantly ameliorated hepatic steatosis, as evidenced by a greater decrease in the total surface area of lipid particles than PO treatment. CO administration preserved mitochondrial morphology in the liver by upregulating the energetic maintenance protein HDHD3. Furthermore, chemical-protein interactions revealed that HDHD3 was linked to the energy homeostatic pathway. Conclusion: CO may benefit liver function by preserving hepatic mitochondrial architecture and increasing energy metabolic activity.
Hepatotropic, antioxidant and antitoxic action of amaranth oil
Background: It is our opinion that amaranth seed oil’s properties merit further study due to their high quantity of squalene. Squalene has been shown to have antitoxic, antioxidant, and hepatotropic properties. The liver is one of the most important organs in the human body, and as a filtering organ, it is subjected to many toxic compounds and free radicals. Thus, protecting the liver with an antioxidant and antitoxic compound could offer significant benefits. Objective: In the present study we have evaluated the antitoxic, antioxidant, and hepatotropic (hepatoprotective) effects of amaranth oil acquired via a patented pressing method. Rats were treated with amaranth oil, a comparative compound, or a control compound and then subjected to various toxic, oxidizing, and other compounds in order to examine amaranth oil’s effects. Results: Amaranth oil was found to have a positive and dose-dependent effect both in vivo and in vitro. Amaranth oil’s hepatoprotective activity was confirmed by both biological and morphological examination. This study suggests that amaranth oil acts to prevent and reduce CT damage in liver tissue. This was especially the case in doses of 300 mg/kg, proved both by normalization of hepatic ferments-markers indexes and morphological examinations. Conclusion: The amaranth oil acquired via a patented pressing method possesses antitoxic and antioxidant activity. In this connection, the amaranth oil can be recommended for prophylaxis of toxic and drug-induced liver lesions and as a component of the functional food and dietetics of various diseases.
Background: The present study aimed to evaluate the hepatoprotective effects of different doses of aqueous bark extract of Terminalia arjuna (TA) on adrenaline-induced hepato-toxicity in male albino rats. Methods: A total number of 48 adult healthy male albino rats were divided into eight groups comprising of 6 animals each. Group-I served as normal control group. All other groups (group-II and group-VI to VIII) were administered adrenaline sub-cutaneously at a dose of 0.3mg/kg body weight. Group- III to V was treated with different doses of aqueous bark extract of TA at doses of 10mg/kg bw/administered orally (For Group-III), 20mg/kg bw/ administered orally (For Group-IV), 40mg/kg bw/administered orally (For Group-V). Group-VI, group-VII and group-VIII were also co-treated with different doses of aqueous bark extract of TA at doses of 10, 20 and 40 mg/kg bw/ administered orally, respectively. Results: Treatment of rats with adrenaline induced alterations in the activities of serum lactate dehydrogenase total (LDH T), lactate dehydrogenase-5(LDH 5), serum glutamate pyruvate transaminase (SGPT), caused elevation in the level of lipid peroxidation and protein carbonylation, a decrease in glutathione content as well as altered the activities of antioxidant enzymes and the enzymes of Kreb’s cycle and respiratory chain. Tissue histomorphological studies also showed considerable damage following adrenaline treatment. Pre-treatment of rats with aqueous bark extract of TA significantly protected against these hepatic damage. Conclusion: The present studies suggest that the aqueous bark extract of TA may be beneficial in ameliorating adrenaline-induced oxidative stress mediated damages in the rat liver.
