Fulltext Bilateral Hydroureteronephrosis with a Hypertrophied, Trabeculated Urinary Bladder

Iqbal S, Raiz I, Faiz I

Malays J Med Sci, 2017 Mar;24(2):106-115.
PMID: 28894411 DOI: 10.21315/mjms2017.24.2.14

Bilateral hydroureteronephrosis involves the dilatation of the renal pelvis, calyces and ureter; it develops secondary to urinary tract obstruction and leads to a build-up of back pressure in the urinary tract, and it may lead to impairment of renal function and ultimately culminate in renal failure. Although clinically silent in most cases, it can be diagnosed as an incidental finding during evaluation of an unrelated cause. In a minority of patients, it presents with signs and symptoms. Renal calculus is the most common cause, but there are multiple non-calculus aetiologies, and they depend on age and sex. Pelviureteric junction obstruction, benign prostatic hypertrophy, urethral stricture, neurogenic bladder, retroperitoneal mass and bladder outlet obstruction are some of the frequent causes of hydroureteronephrosis in adults. The incidence of non-calculus hydronephrosis is more common in males than in females. Ultrasonography is the most important baseline investigation in the evaluation of patients with hydronephrosis. Here, we report a rarely seen case of bilateral hydroureteronephrosis associated with a hypertrophied, trabeculated bladder in an adult male cadaver, suspected to be due to a primary bladder neck obstruction, and analyse its various other causes, clinical presentations and outcomes.
Ascorbic acid inhibits ferric nitrilotriacetate induction of ornithine decarboxylase, DNA synthesis, oxidative stress, and hepatotoxicity in rats

Ansar S, Iqbal M

Toxicol Ind Health, 2015 Nov;31(11):1008-14.

Ascorbic acid (AA) is a naturally occurring phenolic compound with antioxidant properties used in food, cosmetics, and pharmaceutical products. In this study, the effect of AA on ferric nitrilotriacetate (Fe-NTA)-induced hepatotoxicity in rats has been examined. Fe-NTA alone enhances ornithine decarboxylase activity to 4.5-fold and tritiated thymidine incorporation in DNA to 3.6-fold in livers compared with the corresponding saline-treated controls. The enhanced ornithine decarboxylase activity and DNA synthesis showed a reduction to 3.02- and 1.88-fold, respectively, at a higher dose of 2 mg AA per day per animal, compared with the Fe-NTA-treated groups. Fe-NTA treatment also enhanced the hepatic microsomal lipid peroxidation to 1.7-fold compared to saline-treated controls. These changes were reversed significantly in animals receiving pretreatment of AA. The present data shows that AA can reciprocate the toxic effects of Fe-NTA and can serve as a potent chemopreventive agent to suppress oxidant-induced tissue injury and hepatotoxicity in rats.
Ameliorative effect of butylated hydroxyanisole against ferric nitrilotriacetate-induced hepatotoxicity and oxidative stress in rats

Ansar S, Iqbal M

Toxicol Ind Health, 2015 Nov;31(11):967-73.

Ferric nitrilotriacetate (Fe-NTA) is a known renal carcinogen and has been shown to adversely induce oxidative stress and tissue toxicity after both acute and chronic exposure. Present studies were designed to study the hepatoprotective and antioxidant potential of butylated hydroxyanisole (BHA), a phenolic antioxidant used in foods on ferric nitrilotriacetate (Fe-NTA) induced hepatotoxicity in rats. Male albino rats of Wistar strain (4-6 weeks old) weighing 125-150 g were used in this study. Animals were given a single dose of Fe-NTA (9 mg/kg body weight, intraperitoneal) after a week's treatment with BHA. BHA was administered orally once daily for 7 days at doses of 1 and 2 mg/animal/day. The hepatoprotective activity was assessed using various biochemical parameters as serum transaminases (alanine transaminase (ALT), aspartate transaminase (AST)) and lactate dehydrogenase (LDH). Fe-NTA treatment increased ALT, AST, and LDH levels significantly when compared to the corresponding saline-treated group (p < 0.001). Fe-NTA also depleted the levels of glutathione and the activities of antioxidant enzymes namely glutathione reductase and glutathione-S-tranferase (p < 0.05). Pretreatment with BHA significantly decreased ALT, AST and LDH levels in a dose-dependent manner (p < 0.05). BHA also increased antioxidant enzymes level and decreased lipid peroxidation and hydrogen peroxide generation to 1.3-1.5-fold as compared to Fe-NTA-treated group. The results show the strong hepatoprotective activity of BHA which could be due to its potent antioxidant effects.

Ansar S, Iqbal M

Hum Exp Toxicol, 2016 Dec;35(12):1305-1311.
PMID: 26825963

The present study was undertaken to evaluate the effect of diallylsulphide (DAS) against mercuric chloride (HgCl2)-induced oxidative stress in rat livers. Rats were randomly divided into four groups of six rats each and exposed to HgCl2 (50 mg/kg/body weight (b.w.)) intraperitoneally and/or DAS (200 mg/kg/b.w.) by gavage. HgCl2 administration enhanced alanine aminotransferase (AST) and aspartate aminotransferase (ALT) levels (p < 0.05) with reduction in the levels of superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GSH-Px). However, treatment with DAS markedly attenuated HgCl2-induced biochemical alterations in liver and serum transaminases (AST and ALT; p < 0.05). Further, biochemical results were confirmed by histopathological changes as compared to HgCl2-intoxicated rats. Histopathology of liver also showed that administration of DAS significantly reduced the damage generated by HgCl2 The present study suggests that DAS shows antioxidant activity and plays a protective role against mercury-induced oxidative damage in the rat livers.
Antioxidant and nephroprotective potential of butylated hydroxyanisole against ferric nitrilotriacetate-induced oxidative stress and early tumor events

Ansar S, Iqbal M

Hum Exp Toxicol, 2016 Apr;35(4):448-53.
PMID: 26078281 DOI: 10.1177/0960327115591378

The present study was aimed to study protective effect of butylated hydroxyanisole (BHA), a phenolic antioxidant used in foods on ferric nitrilotriacetate (Fe-NTA)-induced nephrotoxicity. Male albino rats of Wistar strain (4-6 weeks old) weighing 125-150 g were used in this study. Animals were given a single dose of Fe-NTA (9 mg kg(-1) body weight) after treatment with BHA (1 and 2 mg animal(-1) day(-1)). Fe-NTA treatment enhanced ornithine decarboxylase (ODC) activity to 5.3-fold, and [(3)H]-thymidine incorporation in DNA to 2.5-fold in kidney compared with the corresponding saline-treated control, whereas glutathione (GSH) levels and the activities of antioxidant enzymes decreased to a range of 2- to 2.5-fold in kidney. These changes were reversed significantly in animals receiving a pretreatment of BHA. The enhanced ODC activity and DNA synthesis showed a reduction to 2.12-fold and 1.15-fold, respectively, at a higher dose of 2 mg BHA day(-1) animal(-1), compared with the Fe-NTA-treated groups. Pretreatment with BHA prior to Fe-NTA treatment increased GSH and the activities of antioxidant enzymes to a range of 1.5- to 2-fold in kidney. The results indicate that BHA suppresses Fe-NTA-induced nephrotoxicity in male Wistar rats.

Garlic contains diallylsulfide (DAS) and other structurally related compounds that are widely believed to be active agents in preventing cancer. This study shows the effect of DAS (a phenolic antioxidant used in foods, cosmetics, and pharmaceutical products) on ferric nitrilotriacetate (Fe-NTA)-induced hepatotoxicity in rats. Male albino rats of Wistar strain weighing 125-150 g were given a single dose of Fe-NTA (9 mg kg(-1) body weight, intraperitoneally) after 1 week of treatment with 100 and 200 mg kg(-1) DAS in corn oil respectively administered through the gavage. Fe-NTA administration led to 2.5-fold increase in the values of both alanine transaminase and aspartate aminotransferase, respectively, and 3.2-fold increase in the activity of lactate dehydrogenase, microsomal lipid peroxidation to approximately 2.0-fold compared to saline-treated control. The activities of glutathione (GSH) and other antioxidant enzymes decreased to a range of 2.2-2.5-fold. These changes were reversed significantly (p < 0.001) in animals receiving a pretreatment of DAS. DAS protected against hepatic lipid peroxidation, hydrogen peroxide generation, preserved GSH levels, and GSH metabolizing enzymes to 60-80% as compared to Fe-NTA alone-treated group. Present data suggest that DAS can ameliorate the toxic effects of Fe-NTA and suppress oxidant-induced tissue injury and hepatotoxicity in rats.

Diazinon (O,O-diethyl-O-[2-isopropyl-6-methyl-4-pyrimidinyl] phosphoro thioate), an organo-phosphate insecticide, has been used worldwide in agriculture and domestic for several years, which has led to a variety of negative effects in non target species including humans. However, its nephrotoxic effects and mechanism of action has not been fully elucidated so far. Therefore, the present study was aimed at evaluating the nephrotoxic effects of diazinon and its mechanism of action with special reference to its possible ROS generating potential in rats. Treatment of rats with diazinon significantly enhances renal lipid peroxidation which is accompanied by a decrease in the activities of renal antioxidant enzymes (e.g. catalase, glutathione peroxidise, glutathione reductase, glucose-6-phosphate dehydrogenase, glutathione S-transferase) and depletion in the level of glutathione reduced. In contrast, the activities of renal γ-glutamyl transpeptidase and quinone reductase were increased. Parallel to these changes, diazinon treatment enhances renal damage as evidenced by sharp increase in blood urea nitrogen and serum creatinine. Additionally, the impairment of renal function corresponds histopathologically. In summary, our results indicate that diazinon treatment eventuates in decreased renal glutathione reduced, a fall in the activities of antioxidant enzymes including the enzymes involved in glutathione metabolism and excessive production of oxidants with concomitant renal damage, all of which are involved in the cascade of events leading to diazinon-mediated renal oxidative stress and toxicity. We concluded that in diazinon exposure, depletion of antioxidant enzymes is accompanied by induction of oxidative stress that might be beneficial in monitoring diazinon toxicity.
The Hepatoprotective Effect of Clidemia hirta against Carbon Tetrachloride (CCl4)-Induced Oxidative Stress and Hepatic Damage in Mice

Liver diseases still represents a major health burden worldwide. Moreover, medicinal plants have gained popularity in the treatment of several diseases, including liver disease. Clidemia hirta possesses many medicinal properties for healing several diseases and for health maintenance. However, the hepatoprotective effects and antioxidative potential of C. hirta have not been fully investigated. In the present study, we evaluated the hepatoprotective and antioxidative potential of C. hirta against carbon tetrachloride (CCl4)-induced liver injuries and oxidative damage in a murine model. Various biochemical changes associated with liver damage and oxidative stress were measured. The mice were pretreated for 14 consecutive days with aqueous extract of C. hirta at selected doses (150 mg/kg body weight [b.w.], 300 mg/kg b.w. and 600 mg/kg b.w.) followed by two doses of CCl4 (1.0 mL/kg b.w.) orally on days 14 and 15. All animals were sacrificed 24 hours after the last dose of CCl4 or saline. Blood and liver tissues were taken quickly for biochemical and histopathological studies to assess the derangement in the functioning of liver. The development of oxidative stress was observed through the escalation of hepatic lipid peroxidation, depletion of glutathione, and reduced antioxidant enzymes (glutathione peroxidase, glutathione reductase, catalase, glutathione S-transferase and quinone reductase). Hepatic damage was evaluated by measuring serum transaminase (ALT and AST). In addition, CCl4-induced hepatic damage was further evaluated using histopathological assessments. However, most of these changes were dependently ameliorated by the pretreatment of mice with a C. hirta dose. These results indicate that the hepatoprotective effect of C. hirta might be due to its antioxidant and free-radical scavenging properties.
Fulltext Eleusine indica L. possesses antioxidant activity and precludes carbon tetrachloride (CCl₄)-mediated oxidative hepatic damage in rats

Environ Health Prev Med, 2012 Jul;17(4):307-15.
PMID: 22207570 DOI: 10.1007/s12199-011-0255-5

OBJECTIVES: The purpose of this study was to evaluate the ability of aqueous extract of Eleusine indica to protect against carbon tetrachloride (CCl₄)-induced hepatic injury in rats.
METHODS: The antioxidant activity of E. indica was evaluated using the 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging assay. The total phenolic content of E. indica was also determined. Biochemical parameters [e.g. alanine aminotransferase (ALT), aspartate aminotransferase (AST), malondialdehyde (MDA), glutathione (GSH), catalase, glutathione peroxidase, glutathione reductase, glutathione S-transferase and quinone reductase] were used to evaluate hepatic damage in animals pretreated with E. indica and intoxicated with CCl₄. CCl₄-mediated hepatic damage was also evaluated by histopathologically.
RESULTS: E. indica extract was able to reduce the stable DPPH level in a dose-dependent manner. The half maximal inhibitory concentration (IC₅₀) value was 2350 μg/ml. Total phenolic content was found to be 14.9 ± 0.002 mg/g total phenolic expressed as gallic acid equivalent per gram of extract. Groups pretreated with E. indica showed significantly increased activity of antioxidant enzymes compared to the CCl₄-intoxicated group (p < 0.05). The increased levels of serum ALT and AST were significantly prevented by E. indica pretreatment (p < 0.05). The extent of MDA formation due to lipid peroxidation was significantly reduced (p < 0.05), and reduced GSH was significantly increased in a dose-dependently manner (p < 0.05) in the E. indica-pretreated groups as compared to the CCl₄-intoxicated group. The protective effect of E. indica was further evident through decreased histopathological alterations in the liver.
CONCLUSION: The results of our study indicate that the hepatoprotective effects of E. indica might be ascribable to its antioxidant and free radical scavenging property.

Value Health, 2015 Nov;18(7):A620.
PMID: 26533480 DOI: 10.1016/j.jval.2015.09.2170

Objectives: To evaluate the prevalence and patterns of CAM use among diabetes patients in Pakistan. In addition, the study also focused on the perceived effectiveness of CAM over conventional therapies, information seeking behavior and CAM disclosure to healthcare providers.
Methods: A prospective, cross-sectional and self-administered questionnaire based study was conducted in tertiary care public hospitals in Pakistan. A prevalence based sample of 350 diabetes patients attending the tertiary hospital in Punjab, Pakistan were selected for the study. All obtained data were analyzed using descriptive and inferential statistics.
Results: Overall, 327 questionnaires were completed and included in the analysis, showing that 52.8% of diabetics had used CAM, with most (62.4%) believing that CAM therapies assist body’s natural forces to heal. CAM usage was significantly associated with gender (P=0.001), level of education (P=0.001), employment status (P=0.03) and monthly income (P<0.001).
Conclusions: Diabetes treatment and management requires compliance to effective therapies at early stages. Healthcare providers should engage diabetics in an open non-judgmental dialogue to ascertain better understanding of diabetes and its management options.
