Abstract
Metabolic disorders are majorly associated with insulin resistance and an impaired glucose tolerance. Since, many of the currently available drugs exhibit adverse effects and are resistant to therapies, natural products are a promising alternate in the alleviation of complex metabolic disorders. In the current study, Syzygium cumini methanolic extract (SCE) was investigated for its anti-diabetic and anti-adipogenic potential using C57BL/6 mice fed on high fat diet (HFD). The HFD fed obese mice were treated with 200 mg/kg SCE and compared with positive controls Metformin, Pioglitazone and Sodium Orthovanadate. The biometabolites in SCE were characterized using Fourier transform infrared and gas chromatography and mass spectroscopy. A reduction in blood glucose levels with improved insulin sensitivity and glucose tolerance was observed in SCE-treated HFD obese mice. Histopathological and biochemical investigations showed a reduction in hepatic injury and nephrotoxicity in SCE-administered HFD mice. Results showed inhibition of PTP1B and an upregulation of IRS1 and PKB-mediated signaling in skeletal muscle. A significant decrease in lipid markers such as TC, TG, LDL-c and VLDL-c levels were observed with increased HDL-c in SCE-treated HFD mice. A significant decrease in weight and adiposity was observed in SCE-administered HFD mice in comparison to controls. This decrease could be due to the partial agonism of PPARγ and an increased expression of adiponectin, an insulin sensitizer. Hence, the dual-modulatory effect of SCE, partly due to the presence of 26% Pyrogallol, could be useful in the management of diabetes and its associated maladies.

Abstract
Background and aim Doxorubicin (DOX) is a chemotherapeutic drug with potential nephrotoxic effects on patients who are on cancer chemotherapy. An interest has been observed in using natural products to ameliorate the potential side effects of DOX. The present study is to investigate the cellular mechanisms underlying the protective effects of Barleria prionitis L. (BP) (Acanthaceae) extracts, DOX-induced acute kidney injury (AKI). Experimental procedure Hexane (25 mg/kg/day), ethyl acetate (80 mg/kg/day), n-butanol (70 mg/kg/day), and water (120 mg/kg/day) extracts of BP, were administered to DOX-induced (5 mg/kg (2500 μL/kg), ip) Wistar rats for four consecutive weeks. At the end of the study, investigations were carried out for the assessment of biomarkers of nephrotoxicity, oxidative stress, inflammation, and apoptosis. Results Treatments with BP extracts significantly reversed DOX-induced elevations in serum and urine biochemical markers of nephrotoxicity (serum creatinine; 21-33%, blood urea nitrogen; 26-58%, β2-microglobulin; 19-22% and urine total protein; 47-67%). There was a reduction in the levels of tumor necrosis factor-α, interleukin-1β, and malondialdehyde in kidney homogenates of rats treated with the n-butanol extract (by 43, 62, and 24%) and water extract (by 57%, 85%, and 26%) (p < 0.05). Immunohistochemical expression of the pro-apoptotic B-cell associated X protein was reduced while the anti-apoptotic B-cell lymphoma gene product 2 protein was increased in kidney tissues after the treatments with BP extracts. Conclusions The selected BP extracts significantly ameliorated DOX-induced AKI. The findings would open new vistas for the development of a drug using the BP extracts to minimize DOX-induced AKI in cancer patients.

Caesalpinia bonducella mitigates oxidative damage by paracetamol intoxication in the kidney and intestine via modulating pro/anti-inflammatory and apoptotic signaling: an In vivo mechanistic insight. 3 Biotech 2023; 13:176.

Abstract
Protracted use of paracetamol at therapeutic/toxic doses readily induces major organ toxicity and poor clinical efficacy. Caesalpinia bonducella seeds possess a diverse range of biological and therapeutic activities. Thus, our study aimed to scrutinize the toxic effects of paracetamol and the potential renal and intestinal protective effects of Caesalpinia bonducella seed extract (CBSE). To Wistar rats, CBSE was administered for 8 days (300 mg/kg, p.o.) with or without paracetamol (2000 mg/kg, p.o.) on the 8th day. Pertinent toxicity assessments in the kidney and intestine were analyzed at the end of the study. The CBASE's phytochemical components were examined using gas chromatography-mass spectrometry (GC-MS). After the study period, study findings evidenced that paracetamol intoxication induced elevation of renal enzyme indicators, oxidative damage, imbalance with the pro/anti-inflammatory production and pro/anti-apoptotic mediators, and tissue injury; all repercussions were alleviated by pre-treatment with CBASE. CBASE considerably reduced (P < 0.05) paracetamol-induced kidney and intestine injury by limiting caspase-8/3 signaling and amplification of inflammation in renal and intestinal tissue by significantly reducing pro-inflammatory cytokine production. As per the GC-MS report, three main bioactive components-Piperine, Isocaryophyllene, and Tetradec-13-en-11-yn-1-ol were predominant and have protective activities. Our study ascertains that CBSE pre-treatment exerts potent renal and intestine protection against paracetamol intoxication. Thus, CBSE could be a prospective therapeutic candidate for protecting the kidney and intestine from the severity of paracetamol intoxication.

Antioxidant Mechanism of Renal and Hepatic Failure Prevention Related to Paracetamol Overdose by the Aqueous Extract of Amblygonocarpus andongensis Stem Bark. BIOMED RESEARCH INTERNATIONAL 2022; 2022:1846558. [PMID: 35909484 PMCID: PMC9334103 DOI: 10.1155/2022/1846558] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/12/2022] [Accepted: 06/30/2022] [Indexed: 11/24/2022]
Abstract
Paracetamol is a commonly used analgesic/antipyretic whose long-term intake or overdose is associated with renal and hepatic injuries. The aim of this study was to determine the hepatonephroprotective mechanisms of the aqueous extract of Amblygonocarpus andongensis stem bark (AEAASB) on renal and hepatic failure resulting from paracetamol overdose. Forty-five rats were divided into nine groups (n = 5); these were treated once daily for 8 days with 5 ml/kg distilled water (normal, negative, and satellite controls); 0.9% normal saline and 140 mg/kg N-acetyl-cysteine (positive controls); 125, 250, and 500 mg/kg AEAASB (test groups); and 500 mg/kg AEAASB (satellite test). On day 8 after different treatments, hepatonephrotoxicity was induced in all the groups except the normal group by oral administration of a single dose of paracetamol (1000 mg/kg). Urinary, hematological, serum, and oxidative stress parameters and in vitro antioxidant activity of AEAASB were evaluated. Histological sections of the liver and kidney were performed. AEAASB significantly decreased urea, creatinine, transaminases, alkaline phosphatase, and bilirubin (p < 0.001) at 500 mg/kg compared to the negative control. Significant decreases in hepatic (p < 0.01) and renal (p < 0.001) malondialdehyde levels were associated with increases in superoxide dismutase, catalase, and reduced glutathione levels in 500 mg/kg AEAASB compared with the negative control. Histological analysis showed that AEAASB prevented paracetamol-induced renal and liver tissue damage. Furthermore, AEAASB revealed a very strong antioxidant activity (inhibitory concentration 50 = 180 μg/ml, antioxidant activity index = 5.55) with an ability to scavenge 63.03% 2,2-diphenyl-2-picrylhy-drazyl radical and reduced ferric iron by 52.68 mgEqVitC/100 g DM. The hepatonephroprotective effect of AEAASB might result from its ability to improve the antioxidant status through the stimulation of antioxidant factors and the scavenging of free radicals. This property could be ascribed to the presence of some classes of bioactive compounds such as phenolic compounds in great amounts.

Abstract
Kidney diseases are expected to become the fifth leading cause of death by 2040. Several physiological failures classified as pre-, intra-, and post-renal factors induce kidney damage. Diabetes, liver pathologies, rhabdomyolysis, and intestinal microbiota have been identified as pre-renal factors, and lithiasis or blood clots in the ureters, prostate cancer, urethral obstructions, prostate elongation, and urinary tract infections are post-renal factors. Additionally, the nephrotoxicity of drugs has been highlighted as a crucial factor inducing kidney injuries. Due to the adverse effects of drugs, it is necessary to point to other alternatives to complement the treatment of these diseases, such as nephroprotective agents. Plants are a wide source of nephroprotective substances and can have beneficial effects in different levels of the physiological pathways which lead to kidney damage. In traditional medicines, plants are used as antioxidants, anti-inflammatories, diuretics, and anticancer agents, among other benefits. However, the mechanism of action of some plants empirically used remains unknown and scientific data are required to support their nephroprotective effects. The present work reviewed the plants with a beneficial effect on kidney diseases. The classification of nephroprotective plants according to the clinical definition of pre-renal, intrinsic, and post-renal factors is proposed to orient their use as complementary treatments.

Abstract
Background and purpose: Stachys pilifera is used in traditional medicine due to its antioxidant, anti-inflammatory, and antimicrobial effects. The goal of this study was to examine the renoprotective activity of the hydroalcoholic extract of aerial parts of S. pilifera on paracetamol (PCM)-induced nephrotoxicity. Experimental approach: The Wistar female rats were randomly divided into four groups including control, PCM, S. pilifera hydroalcoholic extract (SPE), and PCM + SPE. The animals received SPE (500 mg/kg) for one week and PCM (3 g/kg) on the 6th day orally. Kidney function tests and oxidant/antioxidant markers were determined in serum and tissue homogenate, respectively. Protein and mRNA levels of TNF-α, as well as hematoxylin and eosin staining, were assessed in the kidney tissue. Findings/Results: Treatment with SPE in the PCM group significantly decreased blood urea nitrogen and creatinine against the merely PCM rats (P < 0.05). The amount of nitric oxide metabolite and superoxide dismutase activity in the group receiving SPE showed a significant increase compared to PCM rats (P < 0.05). A significant difference in TNF-α levels between the groups was not observed. Histological changes were improved in the rats treated with SPE. Conclusion and implications: Totally, our findings showed that SPE can inhibit PCM nephrotoxicity by enhancing kidney function markers, antioxidant status, and histological changes. Though, more researches are required to estimate the possible mechanism of SPE.

Abstract
Background and Aim: Paracetamol (PCM) ingestion is one of the most frequent global causes of toxicity. Salvadora persica L. is a plant that among many other effects exhibits potent antioxidant, anti-inflammatory, antimicrobial, and anticancer effects. In this study, we investigated the possible protective effect of S. persica aqueous extract in the PCM overdose-induced liver and kidney injury and hematological changes in a mice model. Materials and Methods: Mice were given PCM with and without S. persica pretreatment. Blood cell counts and liver and kidney function biomarkers were measured. Liver and kidney samples were histologically examined. Results: A single overdose of PCM caused significant elevations of alanine and aspartate transaminases, alkaline phosphate, bilirubin, urea, uric acid, and creatinine compared with the control group. In addition, PCM toxicity significantly lowered red blood cell count but insignificantly increased both white blood cell and platelet counts in comparison to the control mice. Pretreatment with S. persica significantly prevented PCM-induced changes in hepatic and renal biomarkers. S. persica also caused marked reversal of hematological changes. Histologically, the liver and kidney showed inflammation and necrosis after PCM treatment, which were significantly reduced in mice pretreated with S. persica. Conclusion: Taken together, S. persica significantly inhibited PCM-induced renal, hepatic, and hematological toxicity, pointing to its possible use in the treatment of liver and renal disorders.

Abstract
Abstract
Background
Paracetamol (PCM), being extensively adapted analgesic and anti-inflammatory drug all over the world, beyond therapeutic dosages, the oxidative stress-involved nephrotoxicity has been evidenced. However, herbal plants are the windfall for the humankind providing solution for most of the wellness breakdowns. Annona squamosa (AS) is one of such plants with enormous therapeutic and nutraceutical potencies. The main aspiration of the current investigation is to evaluate the nephroprotective ability of ethanolic extract of Annona squamosa (EEAS) leaves against paracetamol-induced nephrotoxicity using in vitro human embryonic kidney (HEK)-293 cells and in vivo experiments in Wistar rats through biochemical parameters, oxidative parameters, and histopathological findings.
Results
When HEK-293 cells were incubated with PCM, an increased cell death associated with alterations in the morphology of normal cells was observed. At variable concentrations, HEK-293 cells co-treated with PCM and EEAS extracts gave a significant improvement in cell growth on comparing with PCM treatment showing cytoprotective feature of EEAS with an IC50 28.75 μg/mL. In vivo nephroprotective property was assessed from the amount of blood urea nitrogen (BUN) along with creatinine and uric acid which were reduced (P < 0.001) within serum and compact levels of glutathione, catalase, and superoxide dismutase which were termed as GSH, CAT, and SOD, respectively, were increased (P < 0.001) in kidney tissue homogenate in the treated groups than the PCM alone group. Results were additionally supported by histopathological observations.
Conclusion
The results exhibited that EEAS has impending benefits against PCM-induced nephrotoxicity through in vitro and in vivo experiments.

Abstract
The application of chemicals in industry and agriculture has contributed to environmental pollution and exposure of living organisms to harmful factors. The development of new pharmaceutical agents enabled successful therapy of various diseases, but their administration may be connected with side effects. Oxidative stress has been found to be involved into etiology of numerous diseases as well as harmful action of drugs and chemicals. For some time, plant origin substances have been studied as potential protective agents alleviating toxicity of various substances and symptoms of diseases. The aim of the current review was to present the diversity of the research performed during the last five years on animal models. The outcomes showed a huge protective potential inherent in plant preparations, including alleviating prooxidative processes, strengthening antioxidant defence, ameliorating immune parameters, and reversing histopathological changes. In many cases, plant origin substances were proved to be comparable or even better than standard drugs. Such findings let us suggest that in the future the plant preparations could make adjuvants or a replacement for pharmaceutical agents. However, the detailed research regarding dose and way of administration as well as the per se effects needs to be performed. In many studies, the last issue was not studied, and in some cases, the deleterious effects have been observed.

Abstract
Considering the global health threat posed by kidney disease burden, a search for new nephroprotective drugs from our local flora could prove a powerful strategy to respond to this health threat. In this study we investigated the antihyperuricemic and nephroprotective potential of RA-3, a plant-derived lanosteryl triterpene. The antihyperuricemic and nephroprotective effect of RA-3 was investigated using the adenine and gentamicin induced hyperuricemic and nephrotoxicity rat model. Following the induction of hyperuricemia and nephrotoxicity, the experimental model rats (Sprague Dawley) were orally administered with RA-3 at 50 and 100 mg/kg body weight, respectively, daily for 14 days. Treatment of the experimental rats with RA-3, especially at 100 mg/kg, effectively lowered the serum renal dysfunction (blood urea nitrogen and creatinine) and hyperuricemic (uric acid and xanthine oxidase) biomarkers. These were accompanied by increased antioxidant status with decrease in malondialdehyde content. A much improved histomorphological structure of the kidney tissues was also observed in the triterpene treated groups when compared to the model control group. It is evident that RA-3 possesses the antihyperuricemic and nephroprotective properties, which could be vital for prevention and amelioration of kidney disease.

Spreng, cloves of Allium sativum L., fruits of Garcinia quaesita Pierre, and seeds of Piper nigrum L. is a popular drug which has been used by indigenous practitioners in Sri Lanka for the treatment of diabetes mellitus and dyslipidemia. The acute toxicity assessment was conducted, following a single oral dose of 0.25–2.0 g/kg in healthy rats, and rats were observed up to 14 days. The hot water extract (1.0 g/kg) and the water : acetone extract (0.5, 1.0, and 1.5 g/kg) were administered to Wistar rats for 28 days in the subchronic study. Hypoglycemic and antihyperglycemic activities (dose response studies) of cold water, hot water, and water : acetone extracts of the polyherbal mixture were evaluated at the doses of 0.5, 1.0, and 1.5 g/kg in healthy and streptozotocin-induced diabetic rats (70 mg/kg, ip), respectively. Acute toxicity study showed that the polyherbal drug did not cause any change in animals throughout the experimental period of 14 days. The administration of the hot water extract and the water : acetone extract of the polyherbal drug for 28 days did not produce changes in the selected biochemical and hematological parameters in Wistar rats (p > 0.05). The histological assessment corroborated the biochemical findings with no significant treatment-related changes in the kidney and liver. The treatment of polyherbal drug significantly lowered the serum glucose concentration compared to the diabetic control rats (p < 0.05) while it did not lead to a severe reduction of glucose concentration in healthy rats. The hot water and water : acetone extracts of the polyherbal drug showed a statistically significant improvement on total area under the glucose tolerance curve in diabetic rats (p < 0.05), reflecting dose-dependent antihyperglycemic effects of the drug. Based on the results, we conclude that the aforementioned antidiabetic polyherbal remedy is free of toxic/adverse effects at the equivalent human therapeutic dose in healthy Wistar rats and would be a safe therapeutic agent for long-term treatments.

Abstract
Kidney disease is a worldwide public health problem that affects millions of people worldwide. Globally, many risk factors for kidney disease progression have been identified. The global prevalence of acute and chronic forms of kidney disease is rising continuously. Nephrotoxicity is defined as rapid dysfunction of kidney due to toxic influence of medications and chemicals. Nephroprotective agents are material that has potential to minimize the effects of nephrotoxic agents. Plants have been shown to be potential therapeutic agents to protect against nephrotoxicity. The purpose of the present study was to evaluate the nephroprotective effect of basil leaves extract against thioacetamide (TAA) in male rats. Experimental male rats were divided into four groups. Rats of the first group were served as controls. Rats of the second group were exposed to TAA. Rats of the third group were treated with basil leaves extract and TAA. Rats of the fourth group were treated with basil leaves extract. After the end of experimental duration (6 Weeks), rats of the second group showed significantly increases of serum creatinine, blood urea nitrogen and uric acid levels, while the levels of serum superoxide dismutase and glutathione were significantly decreased. Histopathologically, renal sections from rats treated with only TAA showed several alterations in the structure of most renal corpuscles including a degeneration of glomeruli and Bowman's capsules. Treatment with basil leaves extract improved the observed biochemical and histopathological changes induced by TAA intoxication. These new findings indicate that the extract of basil leaves represent protective roles on biochemical and histopathological changes induced by TAA toxicity due to its antioxidant activities.

Abstract
Abstract
Background
Justicia secunda Vahl. is a medicinal plant used in ethnomedical practice as therapy to manage inflammation. Therefore, this study was designed to evaluate the anti-inflammatory activity of methanol extract of J. secunda leaves (MEJSL) using in vitro and in vivo inflammation models.
Methods
Seventy-percent MEJSL was prepared following standard procedure. In vitro anti-inflammatory assays were performed using heat-induced bovine serum albumin (BSA) denaturation and erythrocyte membrane stabilization assays. Carrageenan and formaldehyde induced inflammation in rat models were used to evaluate the anti-inflammatory activity of MEJSL in vivo. Diclofenac sodium was used as a reference drug. In addition, liver and kidney function assays and hematological analysis were carried out.
Results
Data revealed that varying concentrations of MEJSL significantly (P < 0.05) inhibited heat-induced BSA denaturation and stabilized erythrocyte membrane against hypotonicity-induced hemolysis when compared with diclofenac sodium in a concentration-dependent manner. In vivo study showed that 10 mg/kg body weight (b.w.) diclofenac sodium, 100 and 300 mg/kg b.w. MEJSL suppressed carrageenan-induced paw edema at the sixth hour by 71.14%, 83.08%, and 89.05%, respectively. Furthermore, 10 mg/kg b.w. diclofenac sodium, 100 and 300 mg/kg b.w. MEJSL inhibited formaldehyde-induced paw edema by 72.53%, 74.73%, and 76.48%, respectively. Animals treated with varying doses of MEJSL had reduced plasma aspartate aminotransferase and alanine aminotransferase activities; urea and creatinine concentrations; and modulated hematological parameters when compared with the untreated control group.
Conclusions
Findings from this study showed that MEJSL exhibited substantial anti-inflammatory actions in the in vitro and in vivo models. It also indicated that MEJSL anti-inflammatory mechanisms of action could be through interference with phase 2 inflammatory stressors, upregulation of cytoprotective genes, stabilization of inflammatory cell membranes and immunomodulatory activity.
