Globally mercury (Hg) has been reported as one of heavy metal of known toxicity, noted for inducing public health disasters. Present study examines the therapeutics potentials of Ocimum basilicum on mercury chloride (HgCl2) induced hepatotoxicity in Wistar rats. Thirty adult Wistar rats randomly divided into six groups (A-F) of five rats each. Group A served as control was given 2 mL/day of distilled water, Group B, C, D, E and F received 500 mg/kg body weight (bwt) of O. basilicum extract, 20 mg/kg/bwt of HgCl2, 40 mg/kg bwt of HgCl2, 20 mg/kg bwt of HgCl2 and 500 mg/kg bwt O. basilicum leave extract, 40 mg/kg bwt and 500 mg/kg bwt O. basilicum administered daily by gastric gavage, for 21 consecutive days. The gross anatomical parameters of the liver and liver histology were assessed. Liver oxidative stress was evaluated by liver superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), reduced glutathione (GSH) and malondialdehyde (MDA) assays. The activities of the biomarker enzymes of the liver (alanine transaminase, aspartate transaminase and alkaline phosphatase were assayed). Histological profiles of the liver revealed derangement of the liver cytoarchitecture following consumption of mercury chloride and a marked improvement was observed after O. basilicum administration. Similarly, O. basilicum improved the reduction of antioxidant parameters (SOD, CAT, GPx and GSH) and the increased MDA caused by mercury chloride consumption. O. basilicum thus proffer protection against free radical mediated oxidative stress in mercury chloride-induced hepatotoxicity in rats.

Abstract: Monosodium glutamate (MSG) has been consumed around the world as a food additive in the form of L-glutamic acid. The liver has glutamate receptors, hence its susceptibility to damage due to oxidative stress from consuming excessive MSG. Leek contain antioxidants such as flavonoid, which has potent hepatoprotective properties under certain liver conditions, for the example, oxidative stress, liver fibrosis, and fatty liver. This study aims to see the liver histopathologic findings of wistar rats (Ratus norvegicus) that has been induced by MSG and was given leek juice (Allium fistulosum L.). This was an experimental laboratory study, with 20 wistar rats as subjects. In this study, 173,6 mg per gram body of monosodium glutamate and 20 gram per kilogram body weight of leek juice are administered orally each day. Group A is the negative control group. Group B is given MSG for 14 days. Group C are given MSG for 14 days and were stopped for 5 days. Group D are given MSG for 14 days and were given leek juice. Group A shows normal liver histopathologic features. Group B shows liver cells damage in the form of inflammation and fatty cells. Group C shows regeneration of liver cells but a little bit of inflammation and fatty cells were still found, while in group D there is a wide regeneration of liver cells and there was barely any inflammation and fatty cells. Conclusion: Microscopic features of wistar rat liver after administration of monosodium glutamate for 14 day showed inflammation and fatty cells and then the administration of leek juice for 5 days after MSG administration oon wistar rat showed a wide regeneration of liver cells compared to no administration of leek juice.Keywords: monosodium glutamate, leek, liver. Abstrak: Monosodium glutamate (MSG) telah dikonsumsi di seluruh dunia sebagai penambah rasa makanan dalam bentuk L-glutamic acid (asam glutamat). Hati memiliki resptor terhadap glutamate sehingga rentan mengalami kerusakan akibat stress oksidatif dari konsumsi MSG yang berlebihan. Bawang daun mengandung antioksidan seperti senyawa flavonoid yang memiliki aktivitas hepatoprotektif ampuh pada berbagai kondisi hati seperti strees oksidatif, fibrosis hati, dan perlemakan hati. Penelitian ini bertujuan untuk melihat gambaran histopatologik hati tikus wistar (Rattus norvegicus) yang diinduksi MSG dan diberikan sari air bawang daun (Allium fistulosum L.) Jenis penelitian ini eksperimental laboratorik. Subjek penelitian 20 ekor tikus wistar. Pada penelitian ini digunakan monosodium glutamate 173,6mg/gBB/hari dan sari air bawang daun 20g/kgBB/hari yang diberikan secara oral. Kelompok A (kontrol negatif). Kelompok B diberikan MSG selama 14 hari. Kelompok C diberikan MSG selama 14 hari dan dihentikan selama 5 hari. Kelompok D diberikan MSG selama 14 hari dan diberikan sari air bawang daun. Kelompok A memperlihatkan gambaran histopatologik sel hati normal. Kelompok B memperlihatkan hepatitis dan perlemakan sel hati (steatosis). Kelompok C memperlihatkan sel hati regenerasi namun masih terdapat sedikit sel radang dan perlemakan hati sedangkan pada kelompok D tampak sel hati regenerasi yang luas dan hampir tidak ditemukan peradangan dan perlemakan. Simpulan: Gambaran mikroskopik hati tikus wistar setelah pemberian monosodium glutamate selama 14 hari menunjukkan peradangan (hepatitis) dan perlemakan (steatosis mikrovesikular) kemudian pemberian sari air bawang daun selama 5 hari pasca pemberian MSG pada tikus wistar menunjukkan adanya regenerasi sel hati yang lebih luas dibandingkan dengan tanpa pemberian sari air bawang daun.

OBJECTIVE: To investigate the anti-oxidative and anti-nephrotoxic effects of Resveratrol in cisplatin induced nephrotoxic albino Wistar rats. METHODS: This quasi-experimental study was performed at Isra University, Hyderabad, Pakistan. Thirty male albino Wistar rats were divided into three groups: group-A (control), group-B (cisplatin) and group-C (cisplatin+Resveratrol). Biochemical [serum urea, creatinine and glutathione peroxidase (GPX)] and renal histomorphology was performed in all groups after 21 days of treatment. RESULTS: Difference in mean pre- and post-experimental body weight was observed in all three groups. Mean body weight decreased from 241.7±8.5 gm to 196.50±9.34 gm and from 237±7.4 gm to 207.2±6.56 gm in group-B and group-C respectively. In group-A; mean serum urea was 22.7±2.66 mg/dl, serum creatinine was 0.45±0.05 mg/dl and serum GPX was 1.44±0.13 ηg/ml. In group-B; mean serum urea level was 51±3.65 mg/dl, mean serum creatinine was 0.78±0.05 mg/dl and serum GPX was 0.85±0.11 ηg/ml. In group-C, mean serum urea level was 32.8±1.45 mg/dl, serum creatinine level was 0.41±0.09 mg/dl and serum GPX was 1.53±0.08 ηg/ml. In group-A, renal structure was intact, marked changes were observed in renal histology of group-B while group-C displayed less glomerular damage. The mean distance between visceral and parietal layers of Bowman’s capsule was 69.34±0.87 µm in group-A, 216.5±1.32 µm in group-B while 102.22±1.65 µm in group-C. Areas of peritubular fibrosis and congestion were observed in groups B and C but less prominent in group-C compared with group-B. CONCLUSION: Resveratrol therapy is a potent anti-nephrotoxic regime showing promising results in chemotherapy induced nephrotoxicity and oxidative stress.

Chloroform inhalation is a common method of rodent euthanasia in Nigeria for research purposes. This work is designed to evaluate the consequence of this method of sacrifice on the cerebellum and hippocampus of Wistar rats. Twenty male Wistar rats weighing between 160 and 180 were divided into 4 groups of 5 rats each. Group A served as control and was sacrificed using cervical dislocation (a widely acceptable non-inhalation method of sacrifice). Groups B, C and D were exposed to chloroform for 5 minutes once a day (group B), once a day for 2 days and once a day for 3 days. The brains were removed; four from each group was processed for antioxidant assay while one from each group was fixed in Bouin’s fluid for histological studies. Our results show that chloroform inhalation adversely affected the results of the antioxidant parameters studied in a dose-dependent fashion. That means that the adverse effect worsened as the number of days increased. This was also the case with the histology results as there was evidence of cell necrosis in the cerebellar and hippocampal tissues. This also showed dose dependence. We therefore conclude from our results that when studying the brain tissues or carrying out brain related researches, chloroform inhalation is not the method of choice for rat euthanasia.

Abstract Objectives This study examined the possible protective roles of exogenous glycine (Gly) and L-Arginine (l-Arg) against Diclofenac (DIC)-induced gastro-duodenal damage in rats. Methods Rats were divided into Group A (control), Group B (DIC group) and Groups C–F which were pre-treated for five days with Gly1 (250 mg/kg), Gly2 (500 mg/kg), l-Arg1 (200 mg/kg) and l-Arg2 (400 mg/kg), respectively, before co-treatment with DIC for another three days. Hematological, biochemical and histopathological analyses were then carried out. Results DIC produced significant (p<0.05) reduction in PCV (13.82%), Hb (46.58%), RBC (30.53%), serum total protein (32.72%), albumin (28.44%) and globulin (38.01%) along with significant (p<0.05) elevation of serum MPO activity (83.30%), when compared with control. In addition, DIC increased gastric H2O2 and MDA levels by 33.93 and 48.59%, respectively, while the duodenal levels of the same parameters increased by 19.43 and 85.56%, respectively. Moreover, SOD, GPx and GST activities in the DIC group were significantly (p<0.05) reduced in the stomach (21.12, 24.35 and 51.28%, respectively) and duodenum (30.59, 16.35 and 37.90%, respectively), compared to control. Treatment with Gly and l-Arg resulted in significant amelioration of the DIC-induced alterations although l-Arg produced better amelioration of RBC (29.78%), total protein (10.12%), albumin (9.93%) and MPO (65.01%), compared to the DIC group. The protective effects of both amino acids against oxidative stress parameters and histological lesions were largely similar. Conclusions The data from this study suggest that Gly or l-Arg prevented DIC-induced gastro-duodenal toxicity and might, therefore be useful in improving the therapeutic index of DIC.

The aim of this study was to investigate the clinical efficacy of vanadium complexes on triglycerides (TG), total cholesterol (Chol), uric acid (UA), urea (U), and antioxidant parameters: nonenzymatic (FRAP—ferric reducing ability of plasma, and reduced glutathione—GSH) and enzymatic (glutathione peroxidase—GPx, catalase—CAT, and GPx/CAT ratio) activity in the plasma of healthy male Wistar rats. Three vanadium complexes: [VO(bpy)2]SO4⋅2H2O, [VO(4,4′Me2bpy)2]SO4⋅2H2O, and Na[VO(O2)2(bpy)]⋅8H2O are administered by gavage during 5 weeks in two different diets such as control (C) and high fatty (F) diets. Changes of biochemical and antioxidants parameters are measured in plasma. All three vanadium complexes statistically decrease the body mass growth in comparison to the control and fatty diet. In plasma GSH was statistically increased in all vanadium complexes-treated rats from control and fatty group in comparison to only control group. Calculated GPX/CAT ratio was the highest in the control group in comparison to others.

PURPOSE: To assess the effects of Roux-en-Y jejunal limb length on gastric emptying and enterogastric reflux. METHODS: Seventy male Wistar rats were submitted to antrectomy with Roux-en-Y reconstruction and then were divided into two groups of 35 animals. Group A, short limb (7.5 cm) and Group B, standard limb (15 cm). Group A and B were subdivided into five subgroups each in order to study enterogastric reflux at 30 and 60 minutes and to evaluate gastric emptying at 5, 10 and 15 minutes. In order to measure gastric emptying and enterogastric reflux, radiotracers 99m Tc-Phytate and 99m Tc-DISIDA were respectively used. RESULTS: For gastric emptying, the radiotracer concentration was lower in Group A than in Group B after five minutes. The enterogastric reflux was present, but there were no significant differences between enterogastric reflux indexes concerning both A and B Groups. CONCLUSION: A standard Roux limb, besides being unable to protect the stomach from the enterogastric reflux, may become a functional barrier for gastric emptying.

ABSTRACT Background: Researches on Chagas disease still use several animals and rats, due to size and susceptibility were preferred by many authors. Aim: To develop an experimental model of megacolon in rats inoculated with the strain Y of Trypanosoma cruzi. Methods: Thirty male Wistar rats were distributed in three groups inoculated with different inoculants: Group A: 600000, Group B: 1000000 and Group C: 1500000 blood trypomastigotes of T. cruzi. Animals were sedated intramuscularly at zero inoculation time (T0) and 60 days after inoculation (T60), to perform the barium enema in order to evaluate the dilatation of the different segments of colon in a comparative study of the measurements obtained, using a digital caliper. Evidence of infection was performed by blood smear collected from the animal’s tail 18 days after inoculation with observation of blood forms. Results: Comparing the intestinal diameter of the inoculated animals with 60,0000 trypomastigotes in the T0 of infection with T60 days after the inoculation, significant dilatation was observed between the proximal, medial and distal segments (p<0.01), indicating the establishment of the megacolon model. In addition, comparing intestinal diameter between the different segments, with in the T0 of infection and the T60 after inoculation, significant alterations were observed (p<0.05). Conclusion: The proposed model was possible for in vivo studies of alterations due to infection by T. cruzi and functional alterations of the colon. In addition, the changes manifested in the colon are not directly proportional to the size of the inoculum, but to the time of infection that the animals were submitted, since the animals inoculated with 60,0000 blood forms were the ones which presented the most significant alterations.

Background: The extract of Corchorus olitorius has a reasonable content of vitamins A and C, calcium, iron and fibre, and therefore enjoys a universal application in the treatment of some disease conditions, even as the whole leaf is a very important component of food in so many cultures. Purpose: The study was designed to investigate the effect of Corchorus olitorius extracts on the testis of adult Wistar rats. Method: A total number of thirty two adult Wistar rats weighing between 180 and 200 grammes separated into four groups labeled A,B,C and D respectively were used for the study. Animals in group A which served as the control group were fed with the normal rat chow and water only. The group B rats were administered 100mg/kg body weight of aqueous extract of Corchorus olitorus; while those in group C were administered 500mg/kg body weight of the extract. The group D rats received 1000mg/kg body weight of the extract. For a period of four weeks, the different experimental animal groups received the respective aforementioned treatments once daily, around nine- o’clock in the morning through oral intubation. At the end of the 28 day treatment, the animals were sacrificed and the testes harvested for histological, investigation, and through cardiac puncture, blood samples for some hormonal studies was also collected and investigated using standard laboratory standards. Results: Observations made showed that the extract produced no histological distortions, degenerative or defective effects on the testicular tissues. The testosterone levels of group B, C, and D rats were observed to be significantly higher (P<0.005) than that of the group A (control group).ound: The extract of Corchorus olitorius has a reasonable content of vitamins A and C, calcium, iron and fibre, and therefore enjoys a universal application in the treatment of some disease conditions, even as the whole leaf is a very important component of food in so many cultures.

The aim of the present study was to evaluate the subchronic effects of 3,4-methylenedioxymethamphetamine on several oxidative stress markers: index of lipid peroxidation (ILP), superoxide dismutase (SOD) activity, superoxide radical (O2.-) levels, and reduced glutathione (GSH) levels in the frontal cortex, striatum and hippocampus of the rat. The study included 64 male Wistar rats (200-250g). The animals were treated per os with of 5, 10, or 20 mg/kg of 3,4-methylenedioxymethamphetamine (MDMA) every day for 15 days. The subchronic administration of MDMA resulted in an increase in ILP, SOD and O2.-, and a decrease in GSH, from which we conclude that oxidative stress was induced in rat brain.

AbstractBackgroundMalaria parasites are very vulnerable to oxidative stress during the part of their life cycle when they inhabit the erythrocytes. Studies have shown that dietary intake of antioxidant plays a role in stabilizing oxidative stress.MethodsThe objective of this research work was to examine the antioxidative effect of red palm oil on Plasmodium berghei malaria induced oxidative stress. Sixty (60) mice were distributed into five groups. Group A served as the negative control (healthy mice with normal feed); group B as positive control (healthy mice fed with red palm oil without malaria parasite.while the other groups (C to E) served as the test groups. Group C served as group of healthy mice fed with red palm oil (pelletized), infected with malaria parasite without antimalaria drug. Group D served as group of healthy mice fed with red palm oil (pelletized), infected with malaria parasite and treated with amodiaquine. Group E served as group of healthy mice fed with normal feed, infected with malaria parasite and treated with amodiaquine. The parasitemia levels were estimated on days 1,4 and 5. The activity of oxidative stress enzymes biomarkers were determined spectrophotometrically.ResultGroup A showed a statistically significant increase in the activity of SOD (1.90 ± 0.16 units/mg protein), GST (1.68 ± 0.086 units/L) compared to group C, SOD (3.54 ± 0.83 units/mg protein), GST (2.12 ± 0.20 units/L). Group B showed a statistical significant decrease in the activities of SOD (3.22 ± 0.33 units/mg protein), Catalase (49.11 ± 2.35 µmol/min), GSH-R (31.50 ± 2.48 units/L) compared to group E, SOD (2.18 ± 0.39 units/mg protein), Catalase (44.07 ± 3.88 µmol/min), GSH-R (27.75 ± 1.64 units/L).ConclusionThe dietary intake of red palm oil helps to reduce free radical mediated injury to the tissue thus preventing oxidative stress induced by malaria or any other factors.
