Vancomycin-induced nephrotoxicity (VIN) has been reported to occur in 5–35% of recipient patients. The aims of the study were to evaluate protective effects of Rosa canina (RC) on VIN in rats. Rats were randomly divided into five groups as follows: control group I, group II (received VAN 400 mg/kg/day, every 12 h at doses of 200 mg/kg/day, for 7 consecutive days), group III (VAN + RC 250 mg/kg/day, for 7 consecutive days), group IV (VAN + RC 500 mg/kg/day, for consecutive days), and group V (received RC 500 mg/kg/day, for consecutive 7 days). On the eighth day after anesthetizing the animals, blood samples were taken from the heart, and then, the kidneys were removed to investigate kidney function, oxidative stress, and histopathological marker. Also, the chemical composition of RC extract was identified by GC-MS analysis. Oral dose of 500 mg/kg RC extract significantly reduced the serum levels of blood urea nitrogen (BUN), creatinine (Cr), malondialdehyde (MDA), and nitric oxide (NO) and also the kidney tissue MDA, protein carbonyl, and NO metabolites (nitrite) levels compared to the VAN-treated group ( P < 0.05 ). Based on histopathological analysis, RC extract at the dose of 500 mg/kg inhibited the destructive effects of VAN on kidney tissues. GC-MS analysis indicated that the main compositions were found to be lactose (21.96%), 3-t-butyloxaziridine (20.91%), and 5-oxymethylfurfurole (16.75%). The results indicated that oral administration of RC was able to reduce VAN-induced nephrotoxicity in rats, possibly through antioxidant pathways.

Abstract Purpose Cyclophosphamide is an alkylating agent with nephrotoxicity that constraints its clinical application. Berberine is an isoquinoline derivative alkaloid with biological functions like antioxidant and anti-inflammatory. The current research intended to examine the nephroprotective impacts of berberine against cyclophosphamide-stimulated nephrotoxicity. Methods Forty animal subjects were randomly separated into five categories of control (Group I). Cyclophosphamide (200 mg/kg, i.p., on 7th day) (Group II), and groups III and IV that received berberine 50 and 100 mg/kg orally for seven days and a single injection of cyclophosphamide on 7th day. Group V as berberine (100 mg/kg, alone). On day 8, blood samples were drawn from the retro-orbital sinus to determine serum levels of blood urea nitrogen (BUN), creatinine (Cr), Neutrophil gelatinase-associated lipocalin (NGAL), and kidney injury molecule-1 (KIM-1) as biomarkers for kidney injury. Nitric oxide (NO), malondialdehyde (MDA) and glutathione (GSH) levels, catalase (CAT), superoxide dismutase (SOD), glutathione peroxidase (GPx) activities as oxidative stress factors, tumor necrosis factor- α (TNF-α) and interleukin 1 beta (IL-1β) levels as inflammatory mediators were assessed in kidney tissue. Results The results of this study demonstrated that berberine was able to protect remarkably the kidney from CP-induced injury through decreasing the level of BUN, Cr, NGAL, KIM-1, NO, MDA TNF-α, IL-1β and increasing the level of GSH, CAT, SOD and GPx activities. Conclusion Berberine may be employed as a natural agent to prevent cyclophosphamide-induced nephrotoxicity through anti-oxidant and anti-inflammatory effects.

Background: Limited research studies are reported regarding the toxicological effect of different herbal medicine already used in different countries. Objective: This research study was planned to examine the changes in liver (biochemical and histological) associated with oral administration of somina (acute and sub-acute) in rats. Methodology: Group– I served as control (saline), while other groups (II, III) were daily treated with somina at different doses of 0.285g/kg (group – II), 10g/kg/day (group – III), for 14 (set I), 21 (set II), and 30 (set III) consecutive days.  Each group contains 12 rats. During the study period, signs and behavioral changes, mortality, were observed. At the end of study period, blood sample was drawn directly from heart, for the estimation of liver enzymes: Bilirubin (BIL), alkaline phosphatase (ALP), serum glutamic pyruvic transferase (SGPT), aspartate aminotransferase (SGOT), Albumin (ALB) and total protein (TP). The liver was carefully dichotomized, weighed, and further processed for histopathological analysis. Results: Herbal drug somina was claimed to be practically non-toxic as in rats no mortality was recorded after the oral administration of somina (14, 21 and 30 consecutive days). Liver profile showed non-significant changes in treated group- II and III (P > 0.05), as compared to the control (group- I). The histopathological examination did not reveal any deteriorative effect. Conclusion: It was concluded that oral administration of somina did not produce any significant detrimental effects on rat liver (biochemical and histopathological parameters), even at doses of 10g/kg/day indicating its safe use.

Endothelin-1 has been shown to increase neuronal activity and glutaminergic synaptic transmission by endothelin-A receptors (ETAR) in the nucleus tractus solitarius neurons that play an important role in epileptic seizures. Therefore, BQ-123 as an ETAR antagonist might attenuate neuronal excitability and glutaminergic synaptic transmission. The main purpose of the present study is to investigate the protective effect of acute BQ-123 treatment against pentylenetetrazole (PTZ)-induced tonic–clonic seizures. Wistar albino rats were divided into three groups: control, PTZ, and PTZ + BQ-123 groups. BQ-123 (3 mg/kg, intravenously) was administered for 15 min before injecting with PTZ (50 mg/kg, intraperitoneally). We determined a delay resulting from BQ-123 in “duration of the seizure onset.” “Number of rats with major seizure” also decreased according to scoring with video camera in PTZ + BQ-123 group. In BQ-123-treated group, there were eight rats without a major seizure, but only one rat had a delayed major seizure. The brain tissue glutathione peroxidase activity was significantly decreased in the PTZ and PTZ + BQ-123 groups. According to the results of the control group, there was a significant increase in the protein carbonyl levels of the PTZ group and a significant increase in the nitric oxide levels of the PTZ + BQ-123 group. Histological examination showed an increase in the number of neuronal hyperchromatic nucleus especially in hippocampal gyrus dentatus region of BQ-123-treated group. We concluded that BQ-123 impeded the formation and spread of seizure to a great degree. The beneficial effects of BQ-123 were comparatively supported with biochemical parameters and histological examinations.

Objective. Berberine has been used to treat nonalcoholic steatohepatitis (NASH), which has been addressed in many studies. In this study, we investigated the molecular pharmacology mechanisms of berberine using metabolomic techniques.Methods. Sprague-Dawley rats were randomly divided into three groups (10 rats in each group): (i) normal control group; (ii) high-fat diet- (HFD-) induced NASH model group; and (iii) HFD berberine-treated group (i.d. 200 mg/kg). The handling procedure lasted eight weeks. Then, UPLC-Q-TOF/MS techniques coupled with histopathology and biochemical analyses were adopted to explore the mechanisms of berberine on the protective effects against NASH.Key Findings. (i) According to conventional test results, berberine treatment plays a fighting role in HFD-induced NASH due to its beneficial effects against insulin resistance, inflammation, and lipid metabolism. (ii) Based on UPLC-Q-TOF/MS techniques, metabolic profiles that involved sphingomyelin (SM), phosphatidylcholine (PC), lysophosphatidylcholine (LysoPC), 13-hydroperoxy-9, 11-octadecadienoic acid (13-HpODE), eicosatrienoic acid, docosatrienoic acid, and eicosenoic acid could provide potential metabolic biomarkers to address the pharmacological mechanisms of berberine.Conclusions. The parts of molecular pharmacological mechanisms of berberine for NASH treatment are related to the regulation of metabolic disruption involving phospholipid and unsaturated fatty acids in rats with NASH.

Methimazole (MMI) is a widely used antithyroid drug for hyperthyroidism.However its clinical use is associated with many deleterious effects including hepatotoxicity.MMI induced liver injury is dependent upon bio-activation to toxic intermediates revealing theimportant role of drug metabolizing enzymes in generation of this adverse reaction. Studydesign: Randomized controlled laboratory trial. Period: 04 months from March 2015 to June2015. Settings: Department of Pharmacology and Therapeutics, Army Medical College,Rawalpindi. Aim of the study: The effect of isoniazid (INH) on MMI induced hepatotoxicity wasevaluated in mice. Materials and Method: Thirty male BALB/c mice were randomly dividedinto five groups. Group I served as control group (C-I). Group II (C-II) served as control forINH treated group and received plain drinking water for ten consecutive days. Hepatotoxicitywas induced by single intraperitoneal injection of MMI at a dose of 1000mg/kg in Group III(MMI).Group IV (INH) received isoniazid (0.1%w/v) in drinking water for ten consecutive days.A separate group V (INH +MMI) of isoniazid pretreated mice was given MMI at eleventh day fordetermination of combined effect of both drugs. The extent of hepatic damage was determinedby estimation of serum ALT and ALP along with histopathological analysis of liver samples.Results: MMI resulted in markedly elevated ALT and ALP with hepatic inflammation. INHadministration produced no significant change in both serum biomarkers and histopathologyappearance. Pretreatment of INH with MMI produced insignificant escalation of liver enzymesand microscopic parameters. However, biochemical and histological comparison of this groupwith MMI group revealed statistically consequential differences. Conclusion: INH has beneficialrole in preventing MMI induced hepatic injury.

AbstractLiver plays vital role in detoxification of exogenous and endogenous chemicals. These chemicals as well as oxidative stress may cause liver disorders. This study was aimed to evaluate the hepatoprotective effects of various fractions of Aconogonon alpinum methanolic extract against carbon tetrachloride (CCl4)-induced liver toxicity in mice. First, hepatoprotective potential of various fractions of A. alpinum was assessed and then antioxidant activity and profiling of polyphenolic compounds were assessed. A total of 78 male albino mice (BALB/c) were randomly divided into 13 groups (n = 6); Group I (normal control), Group II (CCl4 only), Group III (CCl4 + silymarin 100 mg/kg) and Groups IV–XIII (CCl4 + various fractions [200 and 400 mg/kg]). Hepatic biochemistry and liver injury were assessed by analysis of serum levels of hepatic enzymes and histopathological analysis, respectively. Results showed that polar fractions (ethyl acetate, n-butanol and aqueous fractions) exhibited highly significant (P < 0.01) reduction in increased level of liver biochemical parameters in a dose-dependent manner with consistent histopathological findings. Likewise, these fractions revealed strong antioxidant potential and polyphenolic compound contents. In conclusion, the present work has revealed promising antioxidant activity, polyphenolic profiling and potential hepatoprotective efficacy. Thus, the significant results unveil the study as a step forward towards evidence-based phytomedicine.

Alcoholic Fatty Liver

Non-alcoholic fatty liver induces many complications to the liver tissue and also serum related parameters. Medicinal plants are the safe therapeutic strategy for the treatment of diseases. In this regards, the present study was conducted to evaluate the effect of Tribulus terrestris L. (Zygophyllales: Zygophyllaceae) extract on non-alcoholic fatty liver in rats. In this experimental study, thirty male Wistar rats were divided into five groups (n = 6). Animals in experimental groups were received high fructose diet (70%) (HDF) daily alone or in combined with daily intraperitoneal injection of 500, 700 and 1,000 mg/kg extract of T. terrestris. Control group of rats was feed with standard chow. The serum levels of biomarkers of liver and serum lipid profiles were assessed, also histopathological examination of liver tissue done. Data were analyzed using One-way ANOVA method followed by Tukey’s post-hoc multiple comparison test and P < 0.05 was considered statistically significant. There were significant improvements for biomarkers of liver tissue (P < 0.05) and serum lipid profiles (P < 0.01) in the HFD-fed rats that were treated with T. terrestris extract compare to HFD-fed group. In addition, accumulation of lipids in hepatocytes was significantly reduced in the HFD-fed + extract administrated groups in comparison to HFD-fed rats (P < 0.01). T. terrestris extract has protective effects against non-alcoholic fatty liver by changing biomarkers of liver tissue, serum lipid profiles and histopathological anomalies of liver tissue, to normal range.

In the porcine coronary artery, regenerated endothelium is dysfunctional as regards the responses to endothelium-dependent agonists. The current study aimed to determine the possible involvement of histamine in such dysfunction. Pigs were treated chronically with pyrilamine (H1 receptor inhibitor, 2 mg·kg−1·day−1) with part of their coronary endothelium and allowed to regenerate for 28 days after balloon denudation. The results showed a reduction in relaxation to bradykinin (Gq protein dependent) only in the pyrilamine-treated group (area under the curve, 269.7 ± 13.4 vs. 142.0 ± 31.0, native endothelium vs. regenerated endothelium) but not in the control group (253.0 ± 22.1 vs. 231.9 ± 29.5, native endothelium vs. regenerated endothelium). The differences in the relaxation to serotonin (Gi protein dependent) between native and regenerated endothelium were not affected by the pyrilamine treatment (control group, 106.3 ± 17.0 vs. 55.61 ± 12.7; and pyrilamine group, 106.0 ± 8.20 vs. 49.30 ± 6.31, native endothelium vs. regenerated endothelium). These findings indicate that during regeneration of the endothelium, the activation of H1 receptors by endogenous histamine may be required to maintain the endothelium-dependent Gq protein-mediated relaxation to bradykinin, suggesting a beneficial role of the monoamine in the process of endothelial regeneration.

To evaluate the effects of Calcium carbide (CaC2) in biological system, an in vivo study was carried out on Long Evans rats. CaC2 was administered orally once daily for one month with specific concentrations. Group- I was considered as the control group (without CaC2), Group - II, III, IV and V were the sample groups treated with CaC2 having concentration of 1g/kg, 2g/kg, 5g/kg and 10g/kg body weight respectively. The experiment was conducted to detect any cellular and molecular level changes caused by CaC2. The histopathology and isozyme assay were performed to analyze the changes in the activities of the genes affected by the free radicals released from CaC2. The molecular analysis included different isozymes namely esterase and acid phosphatase. Polyacrylamide electrophoresis of whole cell extract of control subjects and CaC2 administered rats were performed; subsequently the gels were treated with the substrates for acid phosphatase and esterase respectively. No difference was observed in the whole cell extract band pattern between the control subject and the CaC2 administered rats, which grossly indicates that the CaC2 has no effect on the expression pattern of isozymes (acid phosphatase and esterase). Histopathological analysis of liver, heart, spleen, kidney and lungs were performed to observe any change due to the administration of CaC2. Remarkable changes were observed during the histopathological study of lungs and kidney only. The histopathological analysis of kidney showed the thickening of the lining of collecting tubules with changes in cell structure while lungs were found to be increased moderately in weight, with focal areas of consolidation that was found red-brown to red.
