Paracetamol Toxicity

ABSTRACT Excessive doses of paracetamol have the potential to cause acute kidney injury and even death. Gynura procumbens has been traditionally used as folk-medicine for kidney disease. This study aimed to examine the nephroprotective effect of Gynura procumbens leaf extract against paracetamol-induced nephrotoxicity in rats. Twenty-five male wistar rats (150-200 g) were divided into 5 groups. Healthy control group, placebo group, and 3 extract treatment groups that received either 100 mg/kg, 200 mg/kg or 300 mg/kg dose. The placebo (sodium carboxymethyl cellulose) or extract was given 4 consecutive days prior to paracetamol (2400 mg/kg) administration on day 5. Blood samples were withdrawn before treatment initiated (day 0), after treatment before paracetamol administration (day 5) and 24-hour after paracetamol administration (day 6). Blood samples were analyzed to obtain urea and creatinine levels. In addition, histopathological analysis was performed on the renal tissue.  Paracetamol administration was shown to significantly increase the urea and creatinine levels, and the extract at 300 mg/kg dose was able to significantly prevent the elevation of the renal biomarkers. The histopathological analysis also revealed a significant reduction in renal histopathological injury in 300 mg/kg extract group. It can be concluded that the ethanolic extract of the Gynura procumbens at a dose of 300 mg/kg has a good protective effect on kidney function and tissue structure. Key words: Gynura procumbens, nephroprotective, paracetamol

Zizyphus lotus L. (Desf.) (Z. lotus) is a medicinal plant largely distributed all over the Mediterranean basin and is traditionally used by Moroccan people to treat many illnesses, including kidney failure. The nephrotoxicity of gentamicin (GM) has been well documented in humans and animals, although the preventive strategies against it remain to be studied. In this investigation, we explore whether the extract of Zizyphus lotus L. (Desf.) Fruit (ZLF) exhibits a protective effect against renal damage produced by GM. Indeed, twenty-four Wistar rats were separated into four equal groups of six each (♂/♀ = 1). The control group was treated orally with distilled water (10 mL/kg); the GM treated group received distilled water (10 mL/kg) and an intraperitoneal injection of GM (80 mg/kg) 3 h after; and the treated groups received ZLF extract orally at the doses 200 or 400 mg/kg and injected intraperitoneally with the GM. All treatments were given daily for 14 days. At the end of the experiment, the biochemical parameters and the histological observation related the kidney function was explored. ZLF treatment has significantly attenuated the nephrotoxicity induced by the GM. This effect was indicated by its capacity to decrease significantly the serum creatinine, uric acid, urea, alkaline phosphatase, gamma-glutamyl-transpeptidase, albumin, calcium, sodium amounts, water intake, urinary volume, and relative kidney weight. In addition, this effect was also shown by the increase in the creatinine clearance, urinary creatinine, uric acid, and urea levels, weight gain, compared to the rats treated only with the GM. The hemostasis of oxidants/antioxidants has been significantly improved with the treatment of ZLF extract, which was shown by a significant reduction in malondialdehydes levels. Histopathological analysis of renal tissue was correlated with biochemical observation. Chemical analysis by HPLC-DAD showed that the aqueous extract of ZLF is rich in phenolic compounds such as 3-hydroxycinnamic acid, catechin, ferulic acid, gallic acid, hydroxytyrosol, naringenin, p- coumaric Acid, quercetin, rutin, and vanillic acid. In conclusion, ZLF extract improved the nephrotoxicity induced by GM, through the improvement of the biochemical and histological parameters and thus validates its ethnomedicinal use.

Background: The activation of Nrf2/HO-1 pathway has been shown to protect against cisplatin- induced nephrotoxicity by reducing oxidative stress. Berberine (Ber), an isoquinoline alkaloid, has demonstrated antioxidant, anti-inflammatory and anti-apoptotic activities in various experimental models. Aim: To check the effect of Ber on cisplatin-induced nephrotoxicity and to explore the involved mechanism. Methods: Adult male Wistar rats were divided into 6 groups: Normal, cisplatin-control, treatment groups and per se group. Normal saline and Ber (20, 40 and 80 mg/kg; p.o.) was administered to rats for 10 days. A single intraperitoneal injection of cisplatin (8 mg/kg) was injected on 7th day to induced nephrotoxicity. On 10th day, rats were sacrificed, the kidney was removed and stored for the estimation of various parameters. Results: As compared to cisplatin-control group, Ber pretreatment improved renal function system and preserved renal architecture. It also diminished oxidative stress by upregulating the expression of Nrf2/HO-1 proteins. In addition, Ber attenuated the cisplatin mediated inflammation and apoptosis. Furthermore, it also reduced the phosphorylation of p38/JNK and PARP/Beclin-1 expression in the kidney. Conclusion: Ber attenuated renal injury by activating Nrf2/HO-1 and inhibiting JNK/p38MAPKs/ PARP/Beclin-1 expression which prevented oxidative stress, inflammation, apoptosis and autophagy in renal tissue.

PURPOSE: To analyze the action of gangliosides in peripheral nerve regeneration in the sciatic nerve of the rat. METHODS: The sample was composed of 96 male Wistar rats. The animals were anaesthetized and, after identification of the anaesthesic plane, an incision was made in the posterior region of the thigh, followed by skin and muscle divulsion. The right sciatic nerve was isolated and compressed for 2 minutes. Continuous suture of the skin was performed. The animals were randomly divided into two groups: the experimental group (EG), which received subcutaneous injection of gangliosides, and the control group (CG), which received saline solution (0.9%) to mimic the effects of drug administration. RESULTS: No differences were observed between the experimental and control groups evaluated on the eighth day of observation. At 15 and 30 days the EG showed an decrease in Schwann cell activity and an apparent improvement in fibre organization; at 60 days, there was a slight presence of Schwann cells in the endoneural space and the fibres were organized, indicating nerve regeneration. At 15 and 30 days, the level of cell reaction in the CG had diminished, but there were many cells with cytoplasm in activity and in mitosis; at 60 days, hyperplastic Schwann cells and mitotic activity were again observed, as well as nerve regeneration, but to a lesser extent than in the EG. CONCLUSION: The administration of exogenous gangliosides seems to improve nerve regeneration.

AbstractBackground and objectives: Acute kidney injury (AKI) is a clinical condition associated with a degree of morbidity and mortality despite supportive care, and ischemia/reperfusion injury (I/R) is one of the main causes of AKI. The pathophysiology of I/R injury is a complex cascade of events including the release of free oxygen radicals followed by damage to proteins, lipids, mitochondria, and deranged tissue oxygenation. In this study, we investigated whether the antioxidant ascorbic acid would be able to largely prevent oxidative stress and consequently, reduce I/R-related injury to the kidneys in terms of oxygenation, inflammation, and renal failure. Materials and methods: Rats were divided into three groups (n = 6/group): (1) a time control group; (2) a group subjected to renal ischemia for 60 min by high aortic occlusion followed by 2 h of reperfusion (I/R); and (3) a group subjected to I/R and treated with an i.v. 100 mg/kg bolus ascorbic acid 15 min before ischemia and continuous infusion of 50 mg/kg/hour for 2 h during reperfusion (I/R + AA). We measured renal tissue oxidative stress, microvascular oxygenation, renal oxygen delivery and consumption, and renal expression of inflammatory and injury markers. Results: We demonstrated that aortic clamping and release resulted in increased oxidative stress and inflammation that was associated with a significant fall in systemic and renal hemodynamics and oxygenation parameters. The treatment of ascorbic acid completely abrogated oxidative stress and inflammatory parameters. However, it only partly improved microcirculatory oxygenation and was without any effect on anuria. Conclusion: The ascorbic acid treatment partly improves microcirculatory oxygenation and prevents oxidative stress without restoring urine output in a severe I/R model of AKI.

Background: Dyslipidemia or hyperlipidemia is a consequential condition resulting from derangement in lipid profile. Standard treatment such as Atorvastatin though beneficial, causes many serious adverse effects thus an alternative like Crataegus oxyacantha (Hawthorn) with hypolipidemic potential was investigated. Aims: To evaluate prophylactic and therapeutic hypolipidemic potential of crataegus oxyacantha (hawthorn) fruit in comparison with atorvastatin in murine model of dyslipidemia through assessing physiological parameter i.e., weight and serum biochemical parameters i.e., lipid profile: TC, TGs, VLDL, LDL and HDL. Study design: This experimental study was carried out in research laboratory of Akhtar Saeed Medical and Dental College and National Health Research Centre (NHRC), Lahore Methods: A murine study of 60 days was conducted on 64 male albino Wistar rats (Age  6 weeks) divided into 8 groups with 8 rats each weighing 180-200 grams. Group 1 (healthy control) received normal diet and 2 ml of normal saline for 60 days. Group 2 (disease control) received HFD and 2 ml of normal saline for 30 days while 3-5 (prophylactic groups) were given HFD along with ethanolic extract of Crataegus oxyacantha fruit, atorvastatin and their combination in doses of 40 mg/kg OD, 80 mg/kg OD and 20+40 mg/kg OD orally respectively for the same period. 6-8 (therapeutic groups) received ethanolic extract of Crataegus oxyacantha fruit, atorvastatin and their combination respectively after induction of dyslipidemia from 30th till 60th day in the same doses as mentioned above. Each rat was weighed and fasting samples for biochemical parameters were drawn by cardiac puncture in all groups at baseline and repeated at 30th day in all groups while also at 60th day in therapeutic groups as well as healthy control group. The results were analyzed using one way ANOVA for Mean±SD, post hoc Tukey’s test for group comparison in the Graph-Pad Prism (V.5) software. A p-value ≤ 0.05 was considered as statistically significant. Study period: This study was conducted from September, 2020-November, 2020. Results: Our murine study concludes that Crataegus oxyacantha (40 mg/kg OD orally) when administered prophylactically and therapeutically shows a noteworthy hypolipidemic potential when compared with Atorvastatin (80mg/kg OD orally). Better results were obtained in prophylactic doses as well as in low dose combination with Atorvastatin (20 mg/kg + 40 mg/kg respectively). Conclusion: Results suggest that Crataegus oxyacantha can be used as alternative in treating hyperlipidemias. Keywords: Crataegus oxyacantha, Atorvastatin, Hyperlipidemia.

Background:Ganoderma lucidum (Leyss. Ex. Fr) Karst is a basidiomycete mushroom that has been used for many years as a food supplement and medicine. In Brazil, National Health Surveillance Agency (ANVISA) classified Ganoderma lucidum as a nutraceutical product. The objective of the present work was to observe the effects of an extract from Ganoderma lucidum in rats treated with streptozotocin, and an agent that induces diabetes. Method: Male Wistar rats were obtained from the animal lodging facilities of both University Nove de Julho (UNINOVE) and Lusiada Universitary Center (UNILUS) with approval from the Ethics Committee for Animal Research. Animals were separated into groups: (1) C: Normoglycemic control water; (2) CE: Normoglycemic control group that received hydroethanolic extract (GWA); (3) DM1 + GWA: Diabetic group that received extract GWA; and (4) DM1: Diabetic group that received water. The treatment was evaluated over a 30-day period. Food and water were weighted, and blood plasma biochemical analysis performed. Results: G. lucidum extract contained beta-glucan, proteins and phenols. Biochemical analysis indicated a decrease of plasma glycemic and lipid levels in DM rats induced with streptozotocin and treated with GWA extract. Histopathological analysis from pancreas of GWA-treated DM animals showed preservation of up to 50% of pancreatic islet total area when compared to the DM control group. In plasma, Kyn was present in diabetic rats, while in treated diabetic rats more Trp was detected. Conclusion: Evaluation from G. lucidum extract in STZ-hyperglycemic rats indicated that the extract possesses hypoglycemic and hypolipidemic activities. Support: Proj. CNPq 474681/201.

Sida cordifoliaLinn. (Malvaceae) is a plant used in folk medicine for the treatment of the inflammation of oral mucosa, asthmatic bronchitis, nasal congestion and rheumatism. We studied the hepatoprotective activity of 50 % ethanolic extract ofS. cordifoliaLinn. against alcohol intoxication. The duration of the experiment was 90 d. The substantially elevated levels of toxicity markers such as alanine aminotransferase, aspartate aminotransferase and γ-glutamyl transferase due to the alcohol treatment were significantly lowered in the extract-treated groups. The activity of antioxidant enzymes and glutathione content, which was lowered due to alcohol toxicity, was increased to a near-normal level in the co-administered group. Lipid peroxidation products, protein carbonyls, total collagen and hydroxyproline, which were increased in the alcohol-treated group, were reduced in the co-administered group. The mRNA levels of cytochrome P450 2E1, NF-κB, TNF-α and transforming growth factor-β1 were found to be increased in the alcohol-treated rats, and their expressions were found to be decreased in the co-administered group. These observations were reinforced by histopathological analysis. Thus, the present study clearly indicates that 50 % ethanolic extract of the roots ofS. cordifoliaLinn. has a potent hepatoprotective action against alcohol-induced toxicity, which was mediated by lowering oxidative stress and by down-regulating the transcription factors.

Background: Among aflatoxins, the subtype aflatoxin G1 is one of the most toxic, commonly found in cereals, legumes, dairy and non-alcoholic beers. Aflatoxins have been known as nephrotoxic compounds. In this study, changes in the expression of aquaporin-1, the histopathology of renal tissue and plasma biochemical factors after exposure to aflatoxin G1 were investigated in mice. Methods: Twenty-four adult male mice (weighing 20±2 g) were divided into four groups of six. The control group received the vehicle (0.2 ml) and the three experimental groups were injected intraperitoneally with aflatoxin G1 at 20 μg/kg for 7, 15 or 35 days, respectively. On days 7, 15 and 35, blood samples were drawn from the mice for biochemical analysis of plasma and the kidney tissues were sampled for real-time PCR and histopathological studies. Results: The real PCR results showed a reduction in aquaporin-1 expression in the experimental groups compared to those in the controls (P<0.05). Also, the plasma concentrations of urea and creatinine were significantly increased in the experimental groups compared to those in the controls (P<0.05). Also, the serum sodium and potassium levels had decreased significantly compared to the controls (P<0.05). Various damages were observed in the ureters and glomeruli among the experimental groups compared to those in the controls. Conclusion: Aflatoxin G1 had adverse effects on the renal tissue by reducing the expression of aquaporin-1. Subsequently, there were biochemical manifestations in the serum, consisting of changes in the concentrations of urea, creatinine, sodium and potassium, confirming the histopathological toxicity of aflatoxin G1.
