Abstract
Brain damage caused by ethanol abuse may lead to permanent damage, including severe dementia. The aim of this study was to investigate the effects of ginger powder on ethanol-induced cognitive disorders by examining oxidative damage and inflammation status, and the gene expression of N-methyl-D-aspartate (NMDA) and γ-Aminobutyric acid (GABA)-A receptors in the hippocampus of male rats. 24 adult male Sprague-Dawley rats were allocated randomly to four groups as follows control, ethanol (4g/kg/day, by gavage), ginger (1g/kg/day, by gavage), and ginger-ethanol. At the end of the study, memory and learning were evaluated by the shuttle box test. Moreover, to explore mechanisms involved in ethanol-induced cognitive impairment and the protective effect of ginger, the expression of Nuclear factor kappa B (NF-κB), nuclear factor erythroid 2-related factor 2 (Nrf2), NMDA receptor, and GABA-A receptor was measured along with inflammatory and oxidative biomarkers in the hippocampus tissue. The results showed that ethanol could induce cognitive impairment in the ethanol group, while pretreatment with ginger could reverse it. The gene expression of the NF-κB/ Tumor necrosis factor (TNF)-α/Interleukin (IL)-1β pathway and NMDA and GABA-A receptors significantly increased in the ethanol group compared to the control group. While pretreatment with ginger could significantly improve ethanol-induced cognitive impairment through these pathways in the ginger-ethanol group compared to the ethanol group (P < 0.05). It can be concluded that ginger powder could ameliorate ethanol-induced cognitive impairment by modulating the expression of NMDA and GABA-A receptors and inhibiting oxidative damage and the NF-κB/TNF-α/IL-1β pathway in the rat hippocampus.

Evaluation of Expression of Cytochrome P450 Aromatase and Inflammatory, Oxidative, and Apoptotic Markers in Testicular Tissue of Obese Rats (Pre)Treated with Garlic Powder. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2023; 2023:4858274. [PMID: 36644444 PMCID: PMC9833927 DOI: 10.1155/2023/4858274] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 08/04/2022] [Revised: 12/07/2022] [Accepted: 12/09/2022] [Indexed: 01/06/2023]
Abstract
Today, adolescent obesity is recognized as an epidemic and a cause of reproductive disorders. Decreased testosterone levels occur due to functional defects in the hypothalamus-pituitary axis, excessive activity of cytochrome P450 aromatase enzyme, and testicular dysfunction in these people. Oxidative damage, inflammation, and apoptosis are also the main mechanisms of testicular damage during obesity. The use of herbal products such as garlic can improve this disorder due to its anti-inflammatory and antioxidant properties. Therefore, the aim of this study is to investigate the effect of pretreatment and treatment of garlic powder on the expression of cytochrome P450 aromatase enzyme and the expression of genes involved in testosterone synthesis, inflammation, oxidative damage, apoptosis in testicular tissue, and metabolic function of liver tissue in young male obese rats. Eighty male Wistar rats were divided into the controlled and treated groups. Serum levels of lipid, glucose, and insulin as metabolic factors were measured along with the testicular antioxidant and inflammation markers. The expression of Bcl2, Bax, and caspase-3 along with NF-κB, SREBP-1c, CPT-1beta, Nrf-2, CD36, FAS, CYP19A1, P450scc, StAR, 17βHSD, PPARα, and aromatase (CYP19, P450arom) was also measured. Testicular histological evaluation and spermatogenic process was also performed. The results showed that oxidative, inflammatory, and metabolic factors significantly increased in obese rats. The testicular expression of aromatase, NF-κB, Bax, and caspase 3 increased and Nrf2 expression decreased in obese rats, while (pre) treatment with garlic powder significantly decreased the expression of these genes in obese rats. These results were also confirmed by the findings of the histological evaluation and sperm analysis. It can be concluded that garlic powder could improve reproductive dysfunction in obese rats.

Gao J, Akbari A, Wang T. Green tea could improve elderly hypertension by modulating arterial stiffness, the activity of the renin/angiotensin/aldosterone axis, and the sodium-potassium pumps in old male rats. J Food Biochem 2022; 46:e14398. [PMID: 36181277 DOI: 10.1111/jfbc.14398] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2022] [Revised: 08/15/2022] [Accepted: 08/23/2022] [Indexed: 01/13/2023]
Abstract
Hypertension is a major health problem common in the elderly people. Green tea is a popular beverage recommended in folk medicine for lowering blood pressure. However, the molecular mechanisms involved in the antihypertensive effects of green tea are not fully understood. Therefore, the aim of this study was to investigate the antihypertensive effects of green tea on high-salt diet-induced hypertension in old male rats. Forty old male rats were divided into five groups: control, hypertensive, and hypertensive-green tea (2, 4, and 6 g/kg). Heart rate (HR) and systolic blood pressure (SBP) were measured. Cardiac and renal histology were also performed. Lipid profile, NO, angiotensin II (Ang II), and aldosterone were determined, and the expression of eNOS, ATIR and ATIIR, aldosterone receptor, and Atp1a1 were measured. Green tea could significantly decrease HR and SBP, lipid profiles, renin-angiotensin II-aldosterone system activity, and Ang II signaling in kidney tissue of hypertensive rats (p < .01). It also increased Atp1a1, Nrf2, and eNOS expression along with antioxidant enzymes activity and NO concentration (p < .05) and decreased NF-ĸB and iNOS expression and IL-1β levels in the heart, kidneys, and aorta of rats with hypertension. It can be concluded that green tea can improve salt-induced blood pressure by modulating the function of the renin-angiotensin-aldosterone system, enhancing the synthesis of nitric oxide in the endothelium, increasing antioxidant activity and suppressing inflammation in the heart and kidney, improving the expression of the sodium-potassium pump, and reduction in serum lipids and glucose in aged male rats. PRACTICAL APPLICATIONS: The results of this study showed that green tea could improve hypertension in elderly rats by modulating (1) the expression of the sodium-potassium pump in the heart, kidney, and aortic tissues, (2) the activity of the renin-angiotensin II-aldosterone system in kidney, (3) enhancing antioxidant and anti-inflammatory activities in the heart, aorta, and kidneys, (4) enhancing the synthesis of nitric oxide in the endothelium, and (5) lowering lipid profile. The results of these studies show that the consumption of green tea and its products can be a good candidate for the prevention of cardiovascular diseases such as hypertension in the elderly. In addition, attention to its bioactive compounds can be considered by researchers as an independent therapeutic strategy or adjunctive therapy for the treatment of hypertension.

Xue W, Tang Q, Yang L. The combination of ginger and zinc supplement could improve lead-induced reproductive dysfunction by inhibiting apoptosis mediated by oxidative damage and inflammation. Andrologia 2022; 54:e14577. [PMID: 36574600 DOI: 10.1111/and.14577] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2022] [Revised: 07/14/2022] [Accepted: 08/22/2022] [Indexed: 12/29/2022] Open
Abstract
Due to the growing industry and industrialization of many urban communities, one of the dangers that threaten human life is long-term exposure to heavy metals such as lead. Lead contamination can have a detrimental effect on fertility. On the other hand, the combination of ginger and zinc supplements can be a powerful sexual enhancer. Despite extensive studies on the effect of ginger and zinc on reproduction, the effects of the combination of ginger and zinc supplement on lead-induced reproductive dysfunction are not fully understood. Sixty-four adult male rats were allocated into control, lead acetate (10 mg/kg), ginger (250 mg/kg), ginger-lead group, zinc (120 mg/kg) group, zinc-lead group, ginger-zinc group and ginger-zinc-lead group. The drugs were administrated by gavage for 4 weeks. The concentration of LH, FSH, testosterone, TNF-α, IL-1β, antioxidant enzyme activity, MDA, spermatogenesis, and sperm parameters were measured. The expression of NF-kB, Nrf2, Bcl2, BAX, and Cas-3 was evaluated. The histopathological assessment was also detected. Lead significantly could induce inflammation, apoptosis, and oxidative damage in testis tissue, and decrease hormonal levels, spermatogenesis, and sperm parameters compared to the control group (p < 0.05). While in reverse manner ginger, zinc, and their combination significantly improved all of them compared to the lead group (p < 0.05). These results were also supported by histological findings. It can be concluded that ginger, zinc, and their combination could prevent lead-induced reproductive dysfunction by inhibiting apoptosis mediated by oxidative damage and inflammation and improve reproductive performance.

Abstract
Renal failure caused by gentamicin is mainly mediated through oxidative damage, inflammation, and apoptosis. Hence, vitamin C and selenium, which have antioxidant, anti-inflammatory, and anti-apoptotic properties, and their nanoparticle forms, which have recently received attention, may reduce gentamicin-induced side effects. Therefore, the aim of this study was to investigate the therapeutic effects of vitamin C and selenium, and their nanoparticles on gentamicin-induced renal damage in male rats. 128 adult male Wistar rats were randomly divided into equal sixteen controlled and treated groups. Serum levels of uric acid, blood urea nitrogen, urea, and creatinine were measured. Renal levels of oxidative parameters such as MDA, SOD, and CAT and inflammatory parameters including IL-1β, and TNF-α were measured. Renal expression of Nrf2, NF-κB, Bcl-2, caspase-3, BAX and mTORc1 was also evaluated. The results showed that gentamicin causes oxidative damage, inflammation, apoptosis and disruption of autophagy in kidney tissue in a dose-dependent manner. However, treatment with vitamin C, selenium and their nanoparticles could significantly improve these effects. Also, the results showed that the inflammatory and oxidative parameters and the expression of genes involved in them and apoptosis in the gentamicin groups treated with vitamin C nanoparticles and selenium nanoparticles reduced significantly compared to those treated with vitamin C and selenium. It can be concluded that vitamin C, selenium and their nanoparticles can improve gentamicin-induced kidney damage by inhibiting oxidative damage, inflammation and apoptosis-induced by autophagy, and can be a good option for kidney damage caused by gentamicin or as an adjunctive treatment to reduce its side effects.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Safflower (Carthamus tinctorius) has many applications in folk medicine. Its oil is used traditionally to treat obesity and other metabolic disorders. The anti-hypercholesterolemic and antioxidant effects of this plant have been well documented, but the anti-inflammatory effects and its role on fatty acid oxidation and homeostasis of trace elements are not fully understood. OBJECTIVE The aim of this study was to evaluate the protective effects of different doses of oil and extract of safflower seed against fructose induced metabolic syndrome by investigating the homeostasis of trace elements, TNF-α, and fatty acids metabolism. METHODS Eighty adult male Sprague-Dawley rats were randomly divided into ten groups and treated daily for 16 weeks. At the end of the study, plasma levels of liver enzymes, lipid profiles, blood glucose, insulin and TNF-α were measured. The levels of antioxidant enzymes and lipid peroxidation were also measured along with the expression of CD36, fatty acyl-CoA synthetase (FAS), and Carnitine palmitoyl transferase I (CPT-1) beta genes in the liver. RESULTS The antioxidant enzymes activity significantly decreased and lipid peroxidation, lipid profiles, liver enzymes, and TNF-α significantly increased in fructose-induced metabolic syndrome compared to the control groups, as well as the level of some trace elements significantly changed (p < 0.05). Treatment with oil and safflower seed extract in a dose dependent manner could improve biochemical parameters in groups of metabolic syndrome treated with oil and extract compared to metabolic syndrome (p < 0.05). The results also showed that the expression of above mentioned genes significantly increased in groups of metabolic syndrome treated with oil and extract compared to control and metabolic syndrome groups (p < 0.05). CONCLUSION It can be concluded that safflower seed extract and its oil can improve fructose-induced metabolic syndrome through antioxidant and anti-inflammatory effects, adjustment of homeostasis of trace elements, and enhancing the beta-oxidation capacity of the liver by increasing the expression of CD36, FAS, and CPT-1beta genes.
