Bicalutamide (BCT) is a potent anti-androgen chemotherapeutic drug indicated for prostate cancer. However, BCT is known to cause oxidative stress and impairment of male reproductive function. Whereas Morin (MOR), a flavonoid has been found to be a potent antioxidant, with free radical scavenging capacity. This study investigated the protective effect of MOR on BCT-induced testicular toxicity in Wistar rats. Twenty-four male albino rats were randomized into four groups (n=6/group). Group I which served as control received distilled water. Group II, received 3 mg/kg body weight (bwt) BCT orally (per os); group III received 3 mg/kg/day BCT p.o. plus 100 mg/kg/d MOR p.o. and group IV received 100 mg/kg/d MOR p.o. All treatments lasted for 14 days, thereafter, animals were sacrificed and epididymis and testis were collected for sperm and biochemical analyses. The result revealed that BCT treatment caused a significant increase in abnormal sperm morphology. Sperm production, sperm count, motility and viability were significantly reduced when compared with control (p<0.05). Similarly, testicular superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx),glutathione S-transferase (GST) and acid phosphatase (ACP) activities, as well as ascorbic acid and GSH levels were significantly reduced in the BCT- treated animals when compared to control (p<0.05). Conversely, testicular alkaline phosphatase (ALP), gamma glutamyl transferase (GGT) and lactate dehydrogenese (LDH) activities as well as malondialdehyde (MDA) levels of BCT-treated animals  increased significantly relative to control (p<0.05). However, co-treatment with Morin ameliorated BCT-induced alterations in sperm parameters, ascorbic acid, GSH and MDA levels, as well as LDH, SOD, CAT, GST, GPX, ACP, ALP and GGT activities. Data obtained from this study suggest that Morin protected against altered sperm parameters and testicular oxidative stress caused by BCT.

 Objective: The current study was designed to estimate the potential protective role of the aqueous extract of rosemary (AER) (Rosmarinus officinalis) against trichloroacetic acid (TCA)-created hepatotoxicity in male albino rats.Methods: Forty male albino rats were separated into four groups of ten: Group I served as control; Group II was given AER (200 mg/kg/day) by gavage; Group III received TCA at the dose 50 mg/kg/day, and Group V was treated with AER (200 mg/kg/day) and received TCA (50 mg/kg/day). The experiment was carried out for 2 months.Results: The toxicity of TCA for rats was revealed by an elevation in liver marker enzymes activities (gamma-glutamyl transferase [GGT], alkaline phosphatase [ALP], aspartate transaminase [AST], alanine aminotransferase [ALT]) and conjugated bilirubin (CB) level, and a decrease in albumin and total protein (TP) levels. The TCA administration also caused a significant increase in the activities of catalase (CAT), glutathione peroxidase (GPx) and superoxide dismutase (SOD), and also malondialdehyde (MDA) level in liver tissues. These biochemical effects were accompanied by histological indicators of liver damage. Treatment with ARE recovered the liver damage instigated by TCA, as showed by perfection of liver enzyme markers (GGT, ALT, AST, ALP), CB, TP and albumin; as well as antioxidant parameters (CAT, SOD, GPx) and lipid peroxidation (MDA) and amelioration of histopathology changes in the liver tissues.Conclusion: It could be concluded that AER supplementation for 2 months in TCA-induced toxicity in rats benefited hepatic antioxidant status and improved liver injury and damage in male albino rats exposed to TCA.

Summary Background: Erythropoietin is an anti-apoptotic, anti-inflammatory, angiogenetic cytokine and has protective properties against oxidative stress. In this study we investigated the effects of erythropoietin on the levels (serum and liver tissue) of copper and zinc in cholestatic rats. Methods: Thirty-two Wistar albino rats used in the study were divided into four groups - Group I: Sham; Group II: Erythropoietin; Group III: Obstructive Jaundice; Group IV: Obstructive Jaundice+Erythropoietin. After the first operation, rats were followed up for seven days and then operated for the second time. Rats were sacrificed by intracardiac blood taking, and the liver tissue samples were obtained immediately. Results: Erythropoietin reduces copper, and increases zinc levels in serum and liver tissues after obstructive jaundice (p<0.05). Furthermore, it has been shown that the levels of alanine aminotransferase, aspartate aminotransferase, gamma glutamyl transferase, alkaline phosphatase and total bilirubin/direct bilirubin were significantly lower in Obstructive Jaundice+Erythropoietin group than Obstructive Jaundice group. Conclusions: Erythropoietin affects the changes in copper and zinc levels, thus decreasing the liver damage biochemically in rats with obstructive jaundice. However, further investigations are needed to discover how erythropoietin therapy might reduce target organ damage in cholestatic liver cases by affecting copper and zinc levels.

Objective: The aim of the current study was to investigate the hepatoprotective, nephroprotective, and cholesterol-lowering activity of aqueous extract of Murraya koenigii (MK) leaves against AlCl3-induced oxidative stress in rats. Methods: Wistar albino rats were distributed into six groups (6 each). Group I (control), and Group II administered with distilled water, and aluminum chloride (AlCl3), (40 mg/kg body weight [b.w], oral), respectively. Group III rats were treated with standard Vitamin E (100 mg/kg b.w, p.o) and AlCl3 (40 mg/kg b.w, oral). Group IV, V, and VI received aqueous extract of leaves of Murraya koenigii (AEMK) (100 mg/kg b.w, peroral [p.o], 200 mg/kg b.w, p.o, and 400 mg/kg b.w, p.o), respectively, for a period of 35 days. Results: Histopathological examination was observed deformities in hepatic and renal tissues due to aluminum exposure which augment the aforementioned results. Coadministration of AEMK along with Al significantly restored the serum biomarkers to their near-normal levels and has the ability to overcome Al-induced oxidative stress, manifested by a significant reduction in hepatic and renal malondialdehyde level. It increased cellular antioxidant defense, particularly by increasing GPx, glutathione, GR, and catalase levels, preserved normal hepatic and renal histological architecture. Conclusion: It could be concluded that AEMK has significant radical scavenging activity and can mop up Al-induced toxicity, suggesting hepatoprotective and nephroprotective potential.

The present study was undertaken to investigate the effects of the combination of niacin and chromium(III)-chloride on heart glutathione (GSH), lipid peroxidation (LPO) levels, serum paraoxonase (PON), gamma-glutamyl transferase (GGT) activities and protein carbonyl contents (PCC) of hyperlipidemic rats. In this study, female Swiss albino rats were used. They were divided into four groups. The animals of the first group (group I) were fed with pellet chow. The rats (group II) were fed with a lipogenic diet consisting of 2% cholesterol, 0.5% cholic acid and 20% sunflower oil added to the pellet chow, and given 3% alcoholic water for 60 days. The rats (group III) were fed with the same lipogenic diet and treated by gavage technique with CrCl3 6H2O to a dose of 250 µg/kg and 100 mg/kg niacin for 45 days, 15 days after experimental animals were done hyperlipidemic. Group IV was fed with pellet chow and treated with 250 µg/kg CrCl3 6H2O and 100 mg/kg niacin for 45 days. On the 60th day, the heart tissue and blood samples were taken from animals. As a result, heart LPO, serum GGT activity and serum PCC were increased; serum PON activity and heart GSH levels were decreased in hyperlipidemic rats. Treatment with combined niacin and chromium reversed these effects. In conclusion, the combined treatment with niacin and chromium might induce a protective effect on heart tissue.

Abstract Objectives Dutasteride-Tamsulosin (DUT-TAM), a drug of choice for the treatment of prostate enlargement (Benign Prostatic Hyperplasia, BPH) has been implicated in testicular toxicity. This study investigated the protective effect of morin, a plant-derived flavonoid on DUT-TAM-induced testicular toxicity in Wistar rat. Methods Twenty-four male Wistar rats (110–140 g) were randomly divided into four treatment groups (n=6). Group A animals served as the control and were administered olive oil, Group B animals were administered 5.4 mg/kg b.w. of dutasteride + 3.4 mg/kg b.w of tamsulosin., Group C animals were administered 100 mg/kg b.w. of morin, while Group D animals were administered DUT-TAM (5.4 mg/kg b.w. of dutasteride + 3.4 mg/kg b.w. of tamsulosin) and morin (100 mg/kg b.w.). The administration lasted for two weeks. Results DUT-TAM-induced abnormal sperm morphology (31.8%), significantly reduced (p<0.05) sperm count, sperm motility, live-dead sperm ratio, testicular superoxide dismutase (SOD), catalase, glutathione-S-transferase (GST) and acid phosphatase (ACP) activities, as well as the levels of ascorbic acid and reduced glutathione (GSH) which were ameliorated by co-treatment with morin. Also, DUT-TAM-induced increase in testicular malondialdehyde level and the activities of alkaline phosphatase (ALP), gamma-glutamyl transferase (GGT) and lactate dehydrogenase (LDH) were significantly reversed (p<0.05) by co-treatment with morin. Conclusions These results indicated the protective ability of morin against Dutasteride-Tamsulosin-induced testicular toxicity and oxidative stress.

AbstractBackgroundCadmium serves as a major pollutant in the environment and it has been documented for its widespread harmful effects. This study sought to investigate the prophylactic and the curative effects of aqueous and methanolic leaf extracts of Polyalthia longifolia against cadmium-induced hepatotoxicity in rats.MethodsAnimals in group I served as the normal control and administered distilled water only for 14 days, group II was administered cadmium (4 mg/kg/body weight) for 7 days, groups III and IV rats served as the prophylactic group and were pre-treated with P. longifolia aqueous and methanolic leaf extract for 7 days and then exposed to cadmium for another 7 days, serving as pre-treatment group, groups V, VI, VII, and VIII served as curative groups and were first exposed to cadmium for 7 days and then post-treated with 100 and 200 mg/kg body weight of aqueous extract and 100 and 200 mg/kg body weight of methanolic extract P. longifolia for another 7 days.ResultsPre- and post-treatment with both extracts of P. longifolia revealed a significant hepatoprotective ability by decreasing the alanine transaminase, alkaline phosphatase, aspartate transaminase, acid phosphatase, gamma glutamyl transferase enzymatic activities were elevated due to cadmium intoxication. Pre- and post-treatment with aqueous and methanolic extract of P. longifolia extract significantly decreased hepatic malondialdehyde levels, together with an improvement in the antioxidant status of superoxide dismutase, glutathione peroxidase, catalase, glutathione S-transferase, and reduced glutathione of rats exposed to cadmium. Histopathology examinations also confirm the above biochemical findings.ConclusionThe findings from this work suggested that P. longifolia may be beneficial in ameliorating the cadmium-induced hepatotoxicity and oxidative stress in rats.

This in vitro study analyses the biochemical interaction between saliva and three types of dental composite resins (a direct resin, an indirect resin and a dual-cure resin used for cementation of indirect dental restorations). The resin samples were obtained following a specific protocol and in line with the producers� recommendations; the resin samples were incubated with saliva samples collected from 19 healthy volunteers. The obtained results showed that the tested composite resins did not produce significant changes in oxidative stress parameters that were analysed (albumin, uric acid, GGT / gamma glutamyl transferase, OXSR-1 / oxidative stress responsive kinase 1) and do not influence the inflammatory salivary status reflected by the levels of IL-6 - an inflammatory marker.

Abstract Background Nanomedicine contributes to the efficiency of pharmacological treatments and progresses rapidly. The present study was designed to produce exopolysaccharide (BSEPS) from Bacillus subtilis sp. strain reported in our previous study was further characterized, and its BSEPS for synthesis of the nanoparticle Ag-BSEPS using microwave heating to determine the possible effects of a prepared solution containing Ag-BSEPS versus thioacetamide (TAA) evoked liver fibrosis in Wister albino rats. Nanoparticles with silver (Ag) core have been synthesized in an aqueous solution after exposure of BSEPS to periodate oxidation. Animals were split into four groups: I - control rats, water ad libitum for 6 weeks; II - rats were injected with TAA 200 mg/kg-1 3 times/week for 4 weeks IP; III - Ag-BSEPS 100 mg/kg-1 IP twice a week for 6 weeks; and IV - TAA, as group II followed by Ag-BSEPS as group III. The antifibrotic effects of Ag-BSEPS were appraised by determining different hepatotoxicity indices, oxidative stress, and inflammatory and liver fibrosis markers. Results Nanoparticles were obtained with a diameter size range of 50–100 nm characterized by SEM and TEM without using any harmful reagents. Results evinced considerably reduced activity of liver functions such as transaminases (AST, ALT), gamma-glutamyl transferase (GGT), and alkaline phosphatase (ALP) in the group which received TAA followed by Ag-BSEPS compared to the other group which received only TAA. In the current results, the administration of Ag-BSEPS showed an improvement in the proinflammatory cytokines. On the contrary, the antioxidant enzymes in liver homogenates revealed significant improvement (concentration of glutathione peroxidase (GSH-PX), superoxide dismutase (SOD), and catalase (CAT) increases) in animals with TAA-induced liver damage followed by Ag-BSEPS. Moreover, the activities of the fibrotic markers transforming growth factor-beta 1(TGF-β1) and type III pro-collagen (PCIII) were increased in liver tissues in the group which was given TAA alone as compared to the controls. The percentage of fibrosis of hepatic tissue had a positive correlation with the levels of PCIII and TGF-β1, followed by Ag-BSEPS compared to the TAA group without nanocomposite treatment. Microscopic examinations revealed inhibitory effects of Ag-BSEPS on inflammatory changes and deterrent of liver fibrosis. Conclusion It was suggested that the biochemical and histological amelioration observed in Ag-BSEPS (100 mg/kg-1 twice a week for 6 weeks) treated the fibrotic rats.

Phytochemicals, that is, chemicals present in various plants and herbs , are now becoming important candidates for development of drugs.Wide range of medicinals plants {Plants from which potential photochemicals are isolated for development of drugs for treatment of diseases}present in South Asian countries have now been increasingly utilized for development of phytomedicines. Treatment with ethanol extract of leaf of Cajanus indicus Spreng at a dose of 50 mg /kg body weight for 20 days, after induction of hepatotoxic damage by CCl4, produce significant elevation of the hepatic injury. The liver marker enzymes like(Aspartate Transaminate) AST, GGT(Gamma Glutamyl Transferase), ALT(Alanine Transaminase) and ALP(Alkaline Phosphatase) decreased significantly at the above dose showing the optimum effect against hepatic damage. The liver antioxidant enzymes SOD, catalase, glutathione peroxidase, glutathione reductase and glutathione transferase and the membrane damaging indicators TBARS(Thiobarbituric Acis Reactive Species), conjugate diene and marker of glutathione status indicate the mechanism of healing action to be due to scavenging of free radicals or ROS. The results thus gives a confirmatory proof that the healing action of ethanol extract of leaf of Cajanus indicus Spreng is for shifting of equilibrium from the peroxidant to antioxidant side and the leaf acts as a natural antioxidant and healer of CCl4 induced hepatotoxicity.DOI: http://dx.doi.org/10.3126/jonmc.v1i1.7284 Journal of Nobel Medical College Vol.1(1) 2011 20-26

The use of lopinavir/ritonavir (LPV/r) could be associated with testicular toxicity as a limiting factor. The present study evaluated the effects of melatonin (MT) and alpha lipoic (ALA) acid on LPV/r–induced testicular toxicity in male albino rats. Eighty five male albino rats used for this study were randomized into 6 groups (A-F). Rats in groups A1 and A2 served as placebo and solvent control and were orally exposed to water and 1% ethanol, respectively. Rats in group B were exposed to oral doses of MT (10 mg kg-1/day), ALA (10 mg kg-1/day) and combined doses of MT and ALA, respectively. Rats in group C were exposed to oral doses of LPV/r (22.9/5.71 - 91.4/22.9 mg kg-1/ day), respectively. Rats in group D-F were exposed to oral doses of MT (10 mg kg-1/day), ALA (10 mg kg-1/day) and combined doses of MT and ALA prior to oral exposure to LPV/r (22.9/5.71 - 91.4/22.9 mg kg-1/day), respectively. At the end of 60 days of exposure to drugs, rats were sacrificed; blood was collected and serum extracted and evaluated for testosterone. Testes were collected and evaluated for sperm parameters. LPV/r-treated rats showed significant (P<0.05) and dose-dependent decreases in sperm count, sperm motility, sperm viability and serum testosterone levels with increases in abnormal sperm cells, debris, and primordial sperm cells when compared to placebo control. However, LPV/r-induced changes in sperm parameters and serum testosterone levels were attenuated in rats pretreated with MT and ALA. The best effects were observed in rats pretreated with combined doses of MT and ALA. Melatonin and alpha lipoic acid have potential to reduce testicular toxicity associated with lopinavir/ritonavir treatment.
