Protective effects of Carissa opaca fruits against CCl4-induced oxidative kidney lipid peroxidation and trauma in rat

Protective Effect of Calcium Fructoborate Against Carbon Tetrachloride-Induced Toxicity in Rats

Carbon tetrachloride (CCl₄) is a xenbiotic that can cause cellular damage with free radical production. Calcium fructoborate (CFB) is a boron-based nutritional supplement with antioxidant properties. Calcium fructoborate used in our study is marketed by Future Ceutical Corporation as FruiteX-B, which has a chemical structure similar to the natural form of boron found in edible plants. In this study, it was aimed to determine the antioxidant activity, DNA damage, and histopathological effects of CFB on the liver and kidney tissues of rats in the toxicity induced by CCl₄. During 14 days of treatment, 42 wistar albino rats were divided into 7 in each group, control group, olive oil (0.25 ml twice a week), CFB (1 mg/day), CFB-CCl₄ (1 mg/day, twice a week 0.5 ml), ZY-CFB (0.25 ml/twice a week, 1 mg/2 times day twice), and CCl₄ (0.5 ml twice a week). AST, ALT, HDL, LDH, urea, creatinine, triglyceride, total protein and albumin levels were analyzed in the blood serum of rats. The antioxidant defense system enzymes CAT, GR, GPx, SOD activities and GSH, MDA and 8-OHdG levels in liver and kidney tissues were determined and evaluated. In addition, liver and kidney tissues were examined with only hispatological tests. As a result of the findings, it shows that CCl₄ disrupts antioxidant defense mechanisms by disrupting some enzyme systems in the kidney and liver. CFB (Fruit-XB), a boronbased dietary supplement, regulates antioxidant metabolism by strengthening biochemical metabolic profiles against oxidation, and also has a protective effect against DNA damage caused by oxidation. Thus, it was concluded that CFB has antioxidant property against CCl4-induced liver and kidney toxicity.

The Preventive Effects of Fermented and Germinated Foxtail Millet Whole Grain on Kidney Damage in a Diabetic Mouse Model

Diabetic kidney disease (DKD) is an important complication of diabetes. The prevention of DKD can effectively reduce the mortality rate of diabetic patients and improve their quality of life. The present study examined the effects of fermented and germinated foxtail millet whole grain (FG-FM) on kidney lesions in a diabetic mouse model (Db/Db mice). The results proved that the FG-FM consumption significantly alleviated the kidney tissue damage in the diabetic mouse model. The transcriptome analysis of kidney tissues demonstrated that the overactivation of signaling pathways related to inflammation and immunity in the diabetic mouse model was significantly inhibited with the FG-FM intake. Moreover, the consumption of the FG-FM diet effectively elevated the bacterial diversity, increased the relative abundance of probiotics and decreased the relative abundance of previously reported DKD-related bacteria in the gut microbiota of diabetic mice. Our study confirmed foxtail millet as a potential source of functional food for the non-pharmacological intervention of DKD.

Indigofera linifolia ameliorated CCl4 induced endoplasmic reticulum stress in liver of rat

ETHNOPHARMACOLOGICAL RELEVANCE

Indigofera linifolia (L.f.) Retz. is used in subcontinent for liver disorders, in wounds, febrile eruption and as diuretic.

AIM OF STUDY

The current study evaluates the protective effects of the methanol extract of Indigofera linifolia (ILM) on CCl₄-induced endoplasmic reticulum (ER) stress in liver of rat.

METHODS

ILM was analyzed for phytochemical classes, total phenolic (TPC) and flavonoid content (TFC) as well as multidimensional in vitro antioxidant assays. Male (Sprague Dawley) rats were dispersed into seven groups (6 rats/group) receiving 0.9% saline (1 ml/kg bw), CCl₄ (1 ml/kg bw) diluted in olive oil (3:7 v/v), silymarin (200 mg/kg bw) + CCl₄ (30% v/v), ILM (150 mg/kg bw) + CCl₄ (30% v/v), ILM (300 mg/kg bw) + CCl₄ and ILM alone (either 150 mg/kg bw or 300 mg/kg bw).

RESULTS

ILM extract was constituted of different phytochemical classes. Co-administration of ILM along with CCl₄ to rat revert the level of alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP) and total bilirubin in blood serum and antioxidant parameters in liver. Further, CCl₄ increased the level of ER stress markers and inflammatory mediators while decreased level of GCLC and Nrf-2 in liver tissues of rat. CCl₄-induced histopathological variations were reduced with ILM co-administration in liver tissues.

CONCLUSION

The results suggest that active phyto-constituents of I. linifolia might be responsible for its antioxidant, anti-inflammatory and gene-regulating activities.

Chemical characterization and evaluation of the nephroprotective potential of Parrotiopsis jacquemontiana (Decne) Rehder and Periploca hydaspidis Falc crude extract in CCl4-induced Male Sprague-Dawley Rats

Biochemical, antioxidant, serum, and urine profiles together with physical examination can deliver important information regarding animal health status, and are vital in the diagnosis and treatment of patients. CCl₄, a potent nephrotoxin, was used for causing toxicity in rat kidneys. The present study aimed at exploring the nephroprotective potential of P. jacquemontiana leaves methanol extract (PJM) and P. hydaspidis whole-plant methanol extract (PHM) on kidney cells of male rats after oxidative stress and DNA damage was instigated by CCl₄. Various parameters including enzymatic levels, serum profiles, urine profiles, genotoxicity, and histological studies were conducted. In renal samples of rats treated with CCl₄, the antioxidant enzymes (POD, SOD, CAT), PH level, protein level, and glutathione contents were significantly (p < 0.05) declined whereas renal biochemicals (H₂O₂, TBARS, and nitrite), specific gravity, level of urea, urobilinogen, serum BUN and creatinine were markedly (p < 0.05) increased relative to control group. Co-administration of PJM and PHM with CCl₄ displayed protective ability against CCl₄ intoxication by restoring activities of antioxidant enzymes, urine profile, biochemical parameters, and serum profile in rats. CCl₄ also induced prominent DNA damages and glomerular atrophy with abnormal appearance of glomerulus and Bowman's capsule. These damages results in impaired corticular sections, edema in Bowman's capsule, accumulation of necrotic cells, dilation of convoluted tubules, and narrowing of space between Bowman's capsule, which were successfully ameliorated after co-administration of PJM and PHM fractions in a dose-dependent manner (200 and 400 mg/kg b.w.). The results obtained suggest the therapeutic role of PJM and PHM in oxidative-stress related disorders of kidney and may be helpful in kidney trauma.

Mitigation of cisplatin induced nephrotoxicity by casticin in male albino rats

Cisplatin (CP) is a commonly used, powerful antineoplastic drug, having numerous side effects. Casticin (CAS) is considered as a free radical scavenger and a potent antioxidant. The present research was planned to assess the curative potential of CAS on CP persuaded renal injury in male albino rats. Twenty four male albino rats were distributed into four equal groups. Group-1 was considered as a control group. Animals of Group-2 were injected with 5mg/kg of CP intraperitoneally. Group-3 was co-treated with CAS (50mg/kg) orally and injection of CP (5mg/kg). Group-4 was treated with CAS (50mg/kg) orally throughout the experiment. CP administration substantially reduced the activities of catalase (CAT), superoxide dismutase (SOD), peroxidase (POD), glutathione S-transferase (GST), glutathione reductase (GSR), glutathione (GSH) content while increased thiobarbituric acid reactive substances (TBARS), and hydrogen peroxide (H2O2) levels. Urea, urinary creatinine, urobilinogen, urinary proteins, kidney injury molecule-1 (KIM-1), and neutrophil gelatinase-associated lipocalin (NGAL) levels were substantially increased. In contrast, albumin and creatinine clearance was significantly reduced in CP treated group. The results demonstrated that CP significantly increased the inflammation indicators including nuclear factor kappa-B (NF-κB), tumor necrosis factor-α (TNF-α), Interleukin-1β (IL-1β), Interleukin-6 (IL-6) levels and cyclooxygenase-2 (COX-2) activity and histopathological damages. However, the administration of CAS displayed a palliative effect against CP-generated renal toxicity and recovered all parameters by bringing them to a normal level. These results revealed that the CAS is an effective compound having the curative potential to counter the CP-induced renal damage.

Phytochemical, acute toxicity and renal protective appraisal of Ajuga parviflora hydromethanolic leaf extract against CCl4 induced renal injury in rats

Background

Degenerative kidney diseases are mostly associated with oxidative stress. Natural products are considered as the antioxidants enrich food that can restrict the progress of oxidative stress induced disorders. Therefore, the present study was aimed to evaluate the renal protective effect of Ajuga parviflora leaf extract in carbon tetrachloride intoxicated rats.

Methods

The hydromethanolic extract of A. parviflora leaves was obtained by extracting twice in 60% methanol. The principal bioactive constituents were detected by LC/MS analysis. Toxicity of plant extract was assessed using brine shrimp lethal toxicity test and acute toxicity model on healthy Sprague-Dawley male rats. Nephroprotective effects of plant extract were also evaluated on rats by inducing CCl₄ renal toxicity in comparison with positive control and naïve groups. The dose of A. parviflora administered to animal was 100, 200 and 300 mg/kg. All administrations were given orally on an alternate day basis for 30 days. Urine and serum biomarkers were analyzed, along with antioxidant enzymes. Finally, the DNA damages, lipid peroxides, hydrogen peroxides and nitrites were assessed in rat’s renal tissue. The histopathology alterations in renal tissues were further studied for kidney damages.

Results

The LC/MS analysis confirmed the presence of different important pharmacological compounds in A. parviflora methanolic leaf extract. The key bioactive compounds include pyocyanin, zonisamide, D Saccharic acid, altretamine, carbocyclic thromboxane A2, Sinapyl alcohol, and vitamin C. The important polypeptides identified include Lys-Tyr-Lys, His-His-Lys, Met-Asp-Arg, Phe-Val-Arg, and PyroGlu-Val-Arg. The LD₅₀ of A. parviflora was found to be > 1000 μg/mL. A. parviflora administration significantly subsides CCl₄ toxicity in rats, reduced the elevated level of RBCs, pus and epithelial cells. The abnormal elevated level of specific gravity, creatinine, urobilinogen, urea and albumin were also reduced to normal physiological level. The reduced urinary protein and pH were also normalized. The serum urobilinogen, urea and total bilirubin levels were also reversed to normal levels while the diminished albumin and total protein levels also came to normal. The important phase I and II enzyme levels were also reversed in A. parviflora administered rats. The H₂O₂, thiobarbituric acid reactive substance (TBARS) and nitrite levels were significantly decreased. Furthermore, the damaged DNA and histopathological changes in CCl₄ exposed rats were also highly significantly reversed after the administration of A. parviflora. All effects were significant (P < 0.05) and highly significant (P < 0.005) at 100 and 300 mg/kg respectively.

Conclusion

The restored urine and serum profile of various parameters to normal physiological levels suggests that the A. parviflora has potential antioxidant and repairing potential in renal disorders.

Assessing the ethnobotanical potential of Carissa opaca berries by merging outcomes from metabolomics profiling, enzyme assays, and in silico docking studies

The phytochemical profile of Carissa opaca fruit extract and fractions was established through dereplication strategies employing LC-MS/MS and global natural product social molecular networking (GNPS). Crude extract and fractions were evaluated for their potential to inhibit α-glucosidase and urease in vitro. Flavonoid-O-glycosides, flavonoid-C-glycosides, flavonoids, proanthocyanidin B2, phenolics, and triterpenoids were annotated as the major classes of secondary metabolites present in the extract and fractions. α-Glucosidase inhibition was associated with n-butanol and ethyl acetate fractions comparable to acarbose (IC₅₀ = 120.43 µg/mL) with IC₅₀ values of 123.67 and 131.72 µg/mL, respectively. The ethyl acetate fraction showed good urease inhibition comparable with thiourea (IC₅₀ = 103.71 µg/mL) with an IC₅₀ value of 109.14 µg/mL. Molecular docking studies of compounds observed in the crude extract and bioactive fractions had significant binding scores, which supported results for enzyme inhibition in vitro. This study provided a detailed phytochemical profile of C. opaca fruit and its enzyme inhibition potential.

Pilea umbrosa ameliorate CCl4 induced hepatic injuries by regulating endoplasmic reticulum stress, pro-inflammatory and fibrosis genes in rat

BACKGROUND

Pilea umbrosa (Urticaceae) is used by local communities (district Abbotabad) for liver disorders, as anticancer, in rheumatism and in skin disorders.

METHODS

Methanol extract of P. umbrosa (PUM) was investigated for the presence of polyphenolic constituents by HPLC-DAD analysis. PUM (150 mg/kg and 300 mg/kg) was administered on alternate days for eight weeks in rats exposed with carbon tetrachloride (CCl4). Serum analysis was performed for liver function tests while in liver tissues level of antioxidant enzymes and biochemical markers were also studied. In addition, semi quantitative estimation of antioxidant genes, endoplasmic reticulum (ER) induced stress markers, pro-inflammatory cytokines and fibrosis related genes were carried out on liver tissues by RT-PCR analysis. Liver tissues were also studied for histopathological injuries.

RESULTS

Level of antioxidant enzymes such as catalase (CAT), superoxide dismutase (SOD), peroxidase (POD) and glutathione (GSH) decreased (p < 0.05) whereas level of thiobarbituric acid reactive substance (TBARS), H2O2 and nitrite increased in liver tissues of CCl4 treated rat. Likewise increase in the level of serum markers; alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP) and total bilirubin was observed. Moreover, CCl4 caused many fold increase in expression of ER stress markers; glucose regulated protein (GRP-78), x-box binding protein1-total (XBP-1 t), x-box binding protein1-unspliced (XBP-1 u) and x-box binding protein1-spliced (XBP-1 s). The level of inflammatory mediators such as tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and monocyte chemoattractant protein-1 (MCP-1) was aggregated whereas suppressed the level of antioxidant enzymes; γ-glutamylcysteine ligase (GCLC), protein disulfide isomerase (PDI) and nuclear erythroid 2 p45-related factor 2 (Nrf-2). Additionally, level of fibrosis markers; transforming growth factor-β (TGF-β), Smad-3 and collagen type 1 (Col1-α) increased with CCl4 induced liver toxicity. Histopathological scrutiny depicted damaged liver cells, neutrophils infiltration and dilated sinusoids in CCl4 intoxicated rats. PUM was enriched with rutin, catechin, caffeic acid and apigenin as evidenced by HPLC analysis. Simultaneous administration of PUM and CCl4 in rats retrieved the normal expression of these markers and prevented hepatic injuries.

CONCLUSION

Collectively these results suggest that PUM constituted of strong antioxidant chemicals and could be a potential therapeutic agent for stress related liver disorders.

Hepatoprotective and hematological effects of Justicia secunda Vahl leaves on carbon tetrachloride induced toxicity in rats

Justicia secunda Vahl is an exotic plant that is used to treat medical problems. We investigated the hepatoprotective and hematological effects of aqueous extracts of J. secunda leaves on carbon tetrachloride induced toxicity in rats. Leaf extracts were prepared using hot and cold extraction methods to obtain a hot extract of J. secunda leaves (JSHAE) and a cold extract of J. secunda leaves (JSCAE). Total phenol and flavonoid measurements and antioxidant assays were performed to determine the extract with the greater antioxidant activity. JSHAE was the more effective extract for treatment of carbon tetrachloride (CCl₄) induced hepatotoxicity and hepatotoxicity in rats. Silymarin was used as a standard for comparison. We found that JSHAE contained more total phenol and flavonoid than JSCAE. JSHAE exhibited significantly greater ferric reducing antioxidant power and 1,1-diphenyl-2-picryl hydrazyl and thiobarbituric acid scavenging activity than JSCAE. We also found that in vivo, 100 and 200 mg/kg JSHAE significantly reduced plasma aspartate aminotransferase, alanine aminotransferase, lactate dehydrogenase and total bilirubin levels following CCl₄ induced toxicity compared to untreated rats. JSHAE treated animals exhibited white blood cell, red blood cell, hemoglobin, hematocrit, platelet and procalcitonin levels that were comparable to control animals. Liver sections of rats treated with 200 mg/kg. JSHAE exhibited no abnormalities.

Metabolomic profiling and biological investigation of Tabebuia Aurea (Silva Manso) leaves, family Bignoniaceae

Both ethyl acetate and aqueous fractions of Tabebuia aurea leaves exhibited noteworthy antioxidant and nephroprotective activities against carbon tetrachloride (CCl₄)-induced nephrotoxicity in rats, as evidenced by the remarkable improvements of renal serum biomarkers and histopathological features. Additionally, the ethyl acetate fraction displayed a prominent in vitro antitrypanosomal activity against Trypanosoma brucei; consequently, the leaves were subjected to LC-HR-ESI-MS metabolomic profiling to discover the constituents that possibly underlie their bioactivities. Therefore, ten metabolites were characterized, mostly dominated by flavonoids. Interestingly, two identified constituents viz., 3,9,12,15-octadecatetraenoic acid (9) and 9,11,13-octadecatrienoic acid (10) are reported firstly herein from the genus Tabebuia. Furthermore, among the dereplicated constituents, rutin (5) and kaempferol 3-O-rutinoside (6) exhibited the highest docking scores as effective antitrypanosomal compounds.

Efficacy of two actinomycete extracts in the amelioration of carbon tetrachloride-induced oxidative stress and nephrotoxicity in experimental rats

Actinomycetes are a group of the Gram-positive bacteria famous for their antimicrobial, anticancer, anti-parasitic, and anti-inflammatory activities. This study aimed to investigate the efficacy of two bacterial extracts derived from two soil actinomycete strains (S19 and G30) against carbon tetrachloride (CCl₄)-induced nephrotoxicity in experimental rats. Sixty-four male rats were assigned to four groups of 16 rats in each group. The 1st group was kept as a normal (control) group and given corn oil combined with the used production medium, while the 2nd group received only CCl₄ (CCl₄ group). On the other hand, the 3rd group (CCl₄+S19) was administered CCl₄ and the extract of the actinomycete strain S19 and the 4th group (CCl₄+G30) received CCl₄ and the extract of the actinomycete strain G30, both treatments for 8 weeks. The results revealed that the two actinomycete extracts S19 and G30 could significantly (p < 0.01) lower the elevated levels of serum creatinine, urea, and uric acid caused by the CCl₄ administration. Additionally, the two actinomycete extracts improved the decreased serum total protein. Interestingly, treatment of the CCl₄-intoxicated rats with S19 and G30 extracts remarkably reversed the lowered renal glutathione (GSH), glutathione peroxidase (GSH-Px), peroxidase (Px) and superoxide dismutase (SOD) activities, and the elevated lipid peroxidation (LPO) levels. The histopathological examination of the treated kidney revealed that the two actinomycete extracts improved rats against CCl₄-induced kidney lesions. The present results suggested that the protective effect of the two actinomycete extracts may rely on its effect on reducing the oxidative stress and improving the antioxidant defense system.

Protective effects of anthocyanins from bilberry extract in rats exposed to nephrotoxic effects of carbon tetrachloride

This study examined the nephroprotective effects of 15 different anthocyanins from the bilberry extract on the acute kidney injury caused by CCl₄. The acute nephrotoxicity in rats was induced 24 h after the treatment with a single dose of CCl₄ (3 mL/kg, i.p.).The nephroprotective effects of the anthocyanins were examined in the animals that had been given the bilberry extract in a single dose of 200 mg of anthocyanins/kg daily, 7 days orally, while on the seventh day, 3 h after the last dose of anthocyanins, the animals received a single dose of CCl₄ (3 mL/kg, i.p.) and were sacrificed 24 h later. When the nephrotoxicant alone was administered, it resulted in a substantial increase of the pro-oxidative (TBARS, CD, H₂O₂, XO, and GSSG) and pro-inflammatory markers (TNF-α, NO, and MPO), as well as a noticeable reduction of the antioxidant enzymes (CAT, SOD, POD, GPx, GST, GR) and GSH when compared to the results of the control group. Moreover, the application of CCl₄ significantly influenced a reduction of the renal function, as well as an increase in the sensitive and specific injury indicators of the kidney epithelial cells (β₂-microglobulin, NGAL, KIM1/TIM1) in the serum and urine of rats. The pretreatment of the animals poisoned with CCl₄ with the anthocyanins from the bilberry extract led to a noticeable reduction in the pro-oxidative and pro-inflammatory markers with reduced consumption of the antioxidant defence kidney capacity, compared to the animals exposed to CCl₄ alone. Anthocyanins have been protective for the kidney parenchyma, with an apparent absence of the tubular and periglomerular necrosis, severe degenerative changes, inflammatory mononuclear infiltrates and dilatation of proximal and distal tubules, in contrast to the CCl₄-intoxicated animals. The nephroprotective effects of anthocyanins can be explained by strong antioxidant and anti-inflammatory effects achieved through the stabilization and neutralization of highly reactive and unstable toxic CCl₄ metabolites.

Renoprotective effects of the methanolic extract of Tanacetum parthenium against carbon tetrachloride-induced renal injury in rats

OBJECTIVE

Studies have demonstrated that carbon tetrachloride (CCl₄) increases the generation of reactive oxygen species (ROS) in many tissues including the kidney, heart, lung, brain, and liver. The major aim of the present study was to evaluate the protective activity of Tanacetum parthenium extract (TPE) in renal tissues of CCl₄-intoxicated rats.

MATERIALS AND METHODS

Animals were divided into seven groups of six rats. Group 1 was the control group that was not treated with CCl₄. The rats in the other groups were intraperitoneally injected with CCl₄ (1.5 ml/kg, 1:1 in olive oil) on day 14. Rats in the groups bTPE40, bTPE80, and bTPE120 were gavaged with 40, 80, and 120 mg/kg of TPE, respectively for 14 constitutive days on a daily basis, before CCl₄ administration. Rats in groups aTPE80 and aTPE120 were gavaged with 80 and 120 mg/kg of TPE, respectively, 2, 6, 24 and 48 hr after receiving CCl₄. Blood samples were collected at the end of the 16^th day through an intracardiac puncture and then serums were separated.

RESULTS

CCl₄ increased urea, creatinine, uric acid and creatinine: albumin (C/A) ratio level in serum and decreased total antioxidant and antioxidant enzymes (SOD and GPx) when compared to the control group (p<0.001). But administration of TPE to rats either before or after exposure to CCl₄, attenuated these changes when compared with CCl₄ control group (p<0.05 - p<0.001).

CONCLUSION

TPE had potent nephroprotective effects against oxygen free radicals produced through CCl₄ metabolism.

Protective effects of Monotheca buxifolia fruit on renal toxicity induced by CCl4 in rats

BACKGROUND

Oxidative stress is believed to be a root cause of various degenerative and fibrotic disorders. Dietary foods enrich in antioxidants can cure or curtail the progression of oxidative stress induced disorders. Fruit of Monotheca buxifolia is used locally for digestive and urinary tract disorders. We have evaluated the protective potential of the methanol extract of M. buxifolia (MBM) in rat exposed to carbon tetrachloride (CCl4) toxicity.

METHODS

Powder of the dried fruit of M. buxifolia was extracted twice with 95 % methanol to get the extract (MBM). Presence of polyphenolic constituents was detected by HPLC-DAD (High Performance Liquid Chromatography with Diode Array Detection) analysis. Sprague-Dawley male rats were divided in to six groups with six rats in each. Animals of Group I were kept control, while rats of Group II - Group V were treated intraperitoneally with 1 ml/kg body weight (bw) of CCl4 (30 % v/v; olive oil) 15 dosages in 30 days. Animals of Group III were orally administered silymarin (50 mg/kg bw) while Group IV and V with 200 and 400 mg/kg of MBM on next day of CCl4 treatment. Rats of Group VI were administered only with 400 mg/kg bw of MBM. Biochemical markers of the urine and serum were analyzed. Level of antioxidant enzymes, DNA damages lipid peroxides (TBARS), H2O2 and nitrite was assessed in renal tissues of rat. Histopathological changes in renal tissues of rat were also recorded.

RESULTS

HPLC-DAD analysis of MBM indicated the existence of gallic acid, catechin, caffeic acid and rutin. MBM administration significantly alleviated the toxic effect of CCl4 in rat and decreased the elevated level of RBCs, pus and epithelial cells, specific gravity, creatinine, urobilinogen, urea and albumin while increased the pH and urinary protein. Increase in the level of urobilinogen, blood urea nitrogen (BUN), urea and total bilirubin while decrease of albumin and total protein in serum was restored by the administration of MBM to CCl4 fed rat. Administration of MBM to CCl4 exposed rats significantly increased the activity level of phase I and phase II enzymes and GSH while decreased the level of TBARS, H2O2, nitrite and DNA damages in renal tissues of rat. Furthermore, histopathological alterations induced with CCl4 in renal tissues of rat were also diminished with the administration of MBM.

CONCLUSION

Restoration of various parameters induced with toxic insult of CCl4 in rat suggests the antioxidant and repairing potential of M. buxifolia fruit in kidney disorders.

Proficiencies of Artemisia scoparia against CCl4 induced DNA damages and renal toxicity in rat

BACKGROUND

Artemisia scoparia is traditionally used in the local system of medicine in kidney disorders. This study aimed at scrutinizing the nephroprotective prospective of A. scoparia methanol extract against carbon tetrachloride (CCl4) provoked DNA damages and oxidative stress in kidneys of rat.

METHODS

Dried aerial parts of A. scoparia were powdered and extracted with methanol to obtain the viscous material (ASM). Sprague Dawley male rats (42) were grouped (7) having 6 rats in each. Group I remained untreated and Group II treated intraperitoneally (i.p) with DMSO + olive oil (1 ml/kg body weight (bw). Rats of Group III - VI were treated with CCl4 (1 ml/kg bw; i.p 30 % v/v in olive oil). Animals of Group IV were co-administered with 100 mg/kg bw of silymarin whereas rats of Group V and VI with 150 mg/kg bw and 300 mg/kg bw of ASM at an interval of 48 h for four weeks. Animals of Group VII were administered with ASM (300 mg/kg bw) alone. DNA damages were investigated with comet assay in renal tissues while the oxidative injuries were estimated in serum and renal tissues.

RESULTS

Co-administration of ASM to rats significantly reduced the DNA damages at 300 mg/kg dose as indicated in comet length (40.80 ± 2.60 μm), head length (34.70 ± 2.21 μm), tail length (7.43 ± 1.24 μm) and DNA content in head (88.03 ± 2.27 %) to that of CCl4 for comet length (63.16 ± 2.11 μm), head length (23.29 ± 1.50 μm), tail length (39.21 ± 2.81 μm) and DNA content of head (74.81 ± 2.18 %) in renal cell's nuclei. Increased level of urea, creatinine, bilirubin, blood urea nitrogen whereas decreased concentration of proteins in serum of CCl4 treated animals were restored towards the normal level with co-administration of ASM. CCl4 injection in rats decreased the activity level of CAT, POD, SOD, GST and γ-GT and GSH contents while elevated levels of TBARS, H2O2 and nitrite contents were observed in renal tissues. A noteworthy retrieval of all these parameters and the altered histopathological observations was notified near to the normal values after treatment with both the doses of ASM.

CONCLUSION

Results obtained suggested the therapeutic role of ASM in oxidative stress related disorder of kidneys.
