Hepatoprotective effect of methanol fruit extract of Punica granatum L in highly active antiretroviral therapy-induced toxicity in Wistar rats. Drug Chem Toxicol 2024; 47:243-251. [PMID: 38303124 DOI: 10.1080/01480545.2023.2298891] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2022] [Accepted: 11/01/2023] [Indexed: 02/03/2024]
Abstract
Prolonged use of Highly Active Antiretroviral Therapy (HAART) has been linked to toxicity, particularly hepatotoxicity. There are few effective drugs for HAART patients that promote hepatic cell regeneration and prevent liver injury. Therefore, the purpose of this study was to investigate the hepato-protective activity of Methanol fruit extract of Punica granatum (MFEPG) in HAART-administered rats. Thirty rats weighing between 150-200 g were randomly divided into six groups and each group comprised of five rats. Distilled water was given to the rats in group one. Only HAART was given to the rats in group two. MFEPG at doses of 100 and 400 mg/kg was given to the rats in groups three and four. MFEPG dosages of 100 and 400 mg/kg along with HAART were given to the rats in groups five and six, respectively. All treatments were via oral gavage daily for 40 days. Under halothane anesthesia, all rats were sacrificed on day 41. Liver tissues were utilized for lipid peroxidation marker; Malondialdehyde (MDA), antioxidant enzymes; Superoxide dismutase (SOD) and Catalase (CAT) and histological evaluation, while blood samples were examined for biochemical parameters (AST, ALT, ALP, Total cholesterol, Total protein, and Albumin). The HAART-treated group exhibited a significantly higher amount of the lipid peroxidation end product; MDA, and significantly lower levels of antioxidant enzymes; SOD, and CAT. Liver enzymes and total cholesterol were significantly increased with a significant reduction in Total protein and Albumin levels in the HAART-treated group. Conversely, the liver function biomarkers were returned to normal levels in the HAART and MFEPG-treated groups. Histopathological studies revealed that when HAART-exposed rats were treated with MFEPG, both the biochemical and histological results significantly improved. Thus, the antioxidant activity of MFEPG provides protection against HAART-induced liver oxidative damage. More research is needed to determine the safety of using MFEPG in humans.

Methanol Crude Peel Extract of P. granatum Prevents Oxidative Damage in Kidneys of Rats Exposed to Highly Active Antiretroviral Therapy. J Exp Pharmacol 2024; 16:1-11. [PMID: 38213945 PMCID: PMC10778224 DOI: 10.2147/jep.s438368] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2023] [Accepted: 12/17/2023] [Indexed: 01/13/2024] Open
Abstract
Background Highly Active Antiretroviral Therapy (HAART) has been linked to oxidative damage to kidney cells leading to renal disease in people living with HIV/AIDS on HAART treatment. The toxic effects of HAART affect the patients' quality of life leading to poor adherence to their regimen. Therefore, the purpose of this study was to investigate the nephron-protective activity of methanol crude peel extract of Punica granatum (MPEPG) in HAART-administered Wistar rats. Methods Thirty male albino Wistar rats weighing between 180-200g were randomly divided into six groups of five rats each. Group one served as normal control and was given distilled water only. Group two serves as a negative control and was given HAART at a dosage of 64 mg/kg. Groups 3 and 4 were given 100 and 400 mg/kg of MPEPG, respectively, while groups 5 and 6 were given MPEPG dosages of 100 and 400 mg/kg along with HAART, respectively, for 40 days. The rats were sacrificed under halothane anaesthesia, and the kidneys were removed for histological evaluation, while blood samples were analyzed for biochemical parameters. Results In the HAART (TLD) treated group, there was a significantly high amount of MDA and a lower level of the antioxidant enzymes SOD and CAT. Biochemical analysis revealed that animals treated with HAART (TLD) had significantly higher levels of urea and creatinine, which are biomarkers of kidney damage than the normal control animals. In contrast, all the kidney function markers were returned to normal levels in the HAART-treated group after administration of methanol crude peel extract of P. granatum. The kidney tissues of animals given HAART had considerable structural damage as revealed by histopathological studies. When HAART-exposed rats were treated with MPEPG, both the biochemical and histological results significantly improved. Conclusion Methanol crude peel extract of P. granatum provided effective protection against kidney oxidative injury brought on by HAART because of its anti-oxidant and free radical scavenging properties.

Abstract
Herpes simplex virus type 1 (HSV-1) is a contagious pathogen with a large global footprint, due to its ability to cause lifelong infection in patients. Current antiviral therapies are effective in limiting viral replication in the epithelial cells to alleviate clinical symptoms, but ineffective in eliminating latent viral reservoirs in neurons. Much of HSV-1 pathogenesis is dependent on its ability to manipulate oxidative stress responses to craft a cellular environment that favors HSV-1 replication. However, to maintain redox homeostasis and to promote antiviral immune responses, the infected cell can upregulate reactive oxygen and nitrogen species (RONS) while having a tight control on antioxidant concentrations to prevent cellular damage. Non-thermal plasma (NTP), which we propose as a potential therapy alternative directed against HSV-1 infection, is a means to deliver RONS that affect redox homeostasis in the infected cell. This review emphasizes how NTP can be an effective therapy for HSV-1 infections through the direct antiviral activity of RONS and via immunomodulatory changes in the infected cells that will stimulate anti-HSV-1 adaptive immune responses. Overall, NTP application can control HSV-1 replication and address the challenges of latency by decreasing the size of the viral reservoir in the nervous system.

Abstract
AIMS Hypertension a multifactorial consequence of environmental factors, life style and genetics is the well-recognized risk factor contributing to coronary heart diseases. The antioxidant imbalance, excessive reactive oxygen species (ROS) leads to oxidative stress which is pivotal in progression of hypertension. The present study aims to understand the complex interaction between oxidative stress, inflammation and antioxidant system which is crucial to maintain cellular homeostasis which further can exaggerate hypertension pathophysiology. MATERIALS AND METHODS The metabolic profile of hypertensive and normotensive subjects from Malwa region, Punjab was compared by estimating lipid profile, cardiac, hepatic and renal markers. The oxidative stress markers (protein carbonyls and lipid peroxidation), inflammatory markers (Nitric oxide, Myeloperoxidase and advanced oxygen protein products), and antioxidant enzymes (Superoxide Dismutase, Catalase, and Total Antioxidant Capacity) were analyzed. KEY FINDINGS It is observed that the metabolic markers are altered in hypertensive subjects which further these subjects showed increased oxidative, inflammatory profile and compromised antioxidant status when compared with normotensive subjects. Co-relation analysis validated the involvement of inflammation and oxidative stress in impaired endothelial function and vital organ damage. SIGNIFICANCE OF STUDY These markers may act as early indicators of hypertension which usually do not show any physical symptoms, thus can be diagnosed and treated at the earliest. The current study suggests that disturbed homeostasis, a consequence of altered interaction between antioxidant system and inflammatory events raises the oxidative stress levels which eventually leads to hypertension and associated complications. These indicators can serve as early indicators of future chronic complications of hypertension.

Abstract
BACKGROUND HIV infections are a worldwide health problem. HIV infection reduces CD4+ cell counts. Oxidative stress might play an important role in the stimulation of virus replication and immunodeficiency. Saliva might be the first line of defense against oxidative stress. OBJECTIVE The aim of this study was to evaluate the oxidative stress marker and antioxidant levels of saliva in HIV-infected patients by measuring total antioxidant capacity and malondialdehyde level. METHODS A total of 49 HIV-positive patients and 49 healthy HIV-negative individuals were randomly selected. All the patients were clinically examined. Five mL of unstimulated whole saliva was collected and evaluated by spectrophotometric assay. Data were analyzed with STATA 11. RESULTS Mean ages of the case and control groups were 28 and 33 years, respectively. Salivary malondialdehyde levels were significantly higher in the HIV-positive group (3.68±2.26) compared to the healthy control group (2.79±1.91). Levels of salivary total antioxidant capacity were significantly lower in the HIV-positive group (0.20± 0.09) compared to the control group (0.27±0.10). CONCLUSION The antioxidant defense system in HIV-positive individuals was low and oxidative stress was high in this population. Saliva might be used as a diagnostic tool for antioxidant changes in HIV-positive patients in the future. There were changes in salivary antioxidant defense system and oxidative stress in HIV-positive individuals. Antioxidant supplements might help local salivary and general health statuses.

Abstract
Momordica charantia (M. charantia) is known for its antioxidant and antidiabetic properties. The aim of this study is to investigate the renoprotective effects of M. charantia in rats following treatment with highly active antiretroviral therapy (HAART) regimen triplavar. Adult male Sprague-Dawley rats weighing 178.1-220.5 g (n = 36) were divided into six groups (A-F) with each group comprising of six (n = 6) rats. The drugs and extract were administered via oral gavage. The therapeutic dose of triplavar was adjusted using the human therapeutic dose equivalent for the rat model. Animals were euthanized on the tenth week with kidneys removed for examination and blood obtained via cardiac puncture. Levels of oxidative stress enzymes (superoxide dismutase-SOD, catalase-CAT, and reduced glutathione-GSH) were significantly lowered in all groups not receiving M. charantia. The levels of thiobarbituric acid reactive substances (TBARS) were increased resulting in free radical formation via auto-oxidation. Renal parameters showed no albuminuria, normal blood urea nitrogen (BUN), serum creatinine (SCr) and electrolytes in groups treated with M. charantia. HAART treated (Group B) showed severe albuminuria, a significantly (p < 0.05) raised BUN and SCr and gross electrolyte disturbances. Blood glucose levels were significantly raised in groups not receiving the adjuvant M. charantia (p < 0.05). Histopathology in HAART treated animals showed glomerular capillary abnormalities and cellular infiltrations while M. charantia treated animals showed an essentially normal glomerular appearance with capillary loops and normal cytoarchitecture. In conclusion M. charantia extract administration improved blood glucose levels, restored renal histology, reinstate renal function, reduce body weight loss and restores hyperglycemia.
