Kidney Of Alloxan-induced Diabetic Rats Research Articles

AMELIORATION OF LIVER AND KIDNEY FUNCTION PARAMETERS IN ALLOXAN-INDUCED DIABETIC RATS TREATED WITH 3-[2-(1,5-Dimethyl-3-oxo-2-Phenyl-2,3-Dihydro- 1H-Pyrazol-4-yl) Hydrazinylidene]-1-Phenylbutanedione, and its Ni(II) Complex.

This hydrazone: 3-[2-(1,5-Dimethyl-3-oxo-2-Phenyl-2,3-Dihydro-1H-Pyrazol-4-yl) Hydrazinylidene]-1-Phenylbutanedione (HL), and its Ni (II) Complex ([Ni(HL)2]Cl2) have been reported to possess hypoglycaemic property but the effects of their use on kidney and liver functions in diabetic animals have not been investigated. The study investigated some biochemical parameters in the liver and kidney of alloxan-induced diabetic rats treated with these hydrazone compounds. Diabetes was induced by a single intraperitoneal dose of alloxan (150 mg/kg). Data showed that these compounds induced a significant decrease in serum glucose levels in the diabetic rats. Diabetic rats were administered orally with compounds for fourteen days after which some biochemical indices in the serum, liver and kidney were measured and compared with the control. Serum alkaline phosphatase (ALP), alanine aminotransferase (ALT), aspartate aminotransferase (AST), urea, total protein and creatinine of untreated diabetic group was significantly elevated when compared with the normal control group. The ALP, AST concentrations of diabetic rats treated with low and high doses of HL was observed to be non-significantly (p > 0.05) higher compared with rats in the normal control group A. A significantly (p < 0.05) decrease in the ALT, AST and ALP concentrations of diabetic rats treated with 200 and 400 mg/kg b.w. of HL and [Ni(HL)2]Cl2 were observed when compared with untreated rats in group B. These results suggest that administration of these compounds to diabetic rats did not have any adverse effect on the liver and kidney functions in rats showing that the compounds are not toxic to man.

Lipid Peroxidation, Lipid Profile Changes and Antioxidant Properties of the Combination of Vernonia amygdalina and Ficus exasperata on the Blood, Liver and Kidney of Alloxan-Induced Diabetic Rats

Background: The use of plants known to possess significant antioxidant activities have been widely recommended in the complementary and alternate system of medicine in the treatment of diabetes mellitus. Among the many plant used in Nigeria for the management of DM are Vernonia amygdalina and Ficus exasperata. This study was designed to assess the effect of the combination of the aqueous extract of Vernonia amygdalina and Ficus exasperata on blood glucose level, lipid profile, hepatic enzymes, lipid peroxidation and antioxidant status in alloxan-induced diabetes in rats.
 Method: Twenty five rats were divided into five groups. Four groups were made diabetic by the intra-peritoneal administration of alloxan monohydrate (150mg/kg body weight) while the fifth group served as normal control. Serum, hepatic and renal concentrations of reduced glutathione (GSH) and thiobarbituric acid reactive substances (TBARS) as well as the catalase activity were determined. The blood lipid profile and some hepatic enzymes were also studied.
 Result: The combined extract lowered lipid peroxidation, increase glutathione concentration and catalase activity in all the tissues of diabetic rats. The individual extract lowered the total cholesterol LDL-Cholesterol, coronary risk index (CRI), and atherogenic index (AI) while increasing the concentration of HDL cholesterol in alloxan-induced diabetic rats. Diabetes lowered hepatic enzymes’ activities but the leaf extract significantly increased it.
 Conclusion: It can be concluded that combination of the extracts showed additive effect on each other and it is highly recommended for the management of diabetes.

In vitro and in vivo Antioxidant Properties of Extracts from the Root of Curcuma longa Linn

Many plants possess antioxidants that exhibit additive or synergistic activities. The antioxidant activities of the root of Curcuma longa Linn extracts extracted different solvents were investigated by using several established in vitro systems: α,α-diphenyl-β-picrylhydrazyl (DPPH) radical scavenging activity, hydrogen Peroxide scavenging activity (HPSA), nitric oxide radical scavenging activity (NOSA) and ferric reducing antioxidant power (FRAP). The result showed that methanol extract exhibited greater antioxidant activity in vitro which was statistically significant compared to the other extracts. Based on the in vitro results, the methanol extract was subjected to column chromatography. Six pooled fractions (FI-FVI) were evaluated for in vivo antioxidant activity in liver and kidney of alloxan-induced diabetic rats using a total of forty-five (45) rats which were grouped into nine (9) groups of five (5) rats. The in vivo antioxidants showed a significant decrease in superoxide dismutase (SOD), catalase (CAT) and gluthatione peroxidase (GPx) levels in both liver and kidney of Alloxan-induced diabetic rats. These changes were significantly reversed after treatment with methanol fraction II and the standard drug. Thus, Curcuma longa Linn may be useful in the management of diabetes and oxidative stress.

Effect of Artocarpus altilis fruit based-diet on liver and kidney function indices on alloxan-induced diabetic rats

BACKGROUND: The prevalence of diabetes mellitus continues to increase alarmingly in spite of years of intensive research. The need to explore alternative therapy such dietary and phytotherapy has been gaining attention in the management/treatment of diabetes mellitus. OBJECTIVE: The present research work was carried out to investigate the biochemical indices in the liver and kidney of alloxan-induced diabetic rats fed with Artocarpus altilis fruit based-diet. METHODS: Diabetes was induced by a single intraperitoneal injection of alloxan (150 mg/kg) in albino rats. A total of thirty two albino rats (Rattus norvegicus) were grouped into four; control (non-diabetic rat), diabetic untreated rats, diabetic rats administered with metformin daily and diabetic rats fed with Artocarpus altilis fruit based-diet groups. Biochemical indices in the serum, liver and kidney were determined. RESULTS: The results shows significant (P < 0.05) decrease in alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, bilirubin, urea, creatinine and lipid peroxidation of diabetic fed with Artocarpus altilis fruit based-diet. Also diabetic rats fed with Artocarpus altilis fruit based-diet demonstrated significant increase (p < 0.05) in albumin and total protein concentrations as well as antioxidant enzymes activities when compared with diabetic untreated rats and diabetic rats administered with metformin daily. CONCLUSION: The results obtained in this study demonstrated that consumption of Artocarpus altilis fruit based-diet may ameliorate the liver and kidney function indices of alloxan-induced diabetic rats.

Protective Effect of Galactomannan Extracted from Iraqi &lt;i&gt;Lycium barbarum&lt;/i&gt; L. Fruits against Alloxan-Induced Diabetes in Rats

Lycium barbarum L. (Solanaceae) is widely used in Iraqi Ayurvedic medicine for the treatment of diabetes mellitus. The present investigation was done to evaluate the effects of polysaccharide (galactomannan) from Lycium barbarum L. Fruits (GLBF) on serum blood glucose, serum lipid profile and lipid peroxidation and antioxidant defence system in liver and kidney of alloxan-induced diabetic rats. GLBF was found to be non-toxic at 1000 mg kg-1, as no deaths or hazardous signs were recorded during treatment or the observation period (24 and 72 h) in either control or treated groups of mice. In GLBF (500 mg kg-1), the onset was 4 h, the peak effect was 6 h but the effect waned at 24 h. In the chronic study, repeated administration (once a day for 21 days) of the glibenclamide and GLBF caused a significant reduction in the serum glucose level as compared to the diabetic control group. GLBF (500 mg kg-1) treatment prevented a decrease in the body weight of the diabetic rats. Moreover, the results revealed that GLBF (500 mg kg-1) treatment for 21 days significantly (p

Astaxanthin from shrimp by-products ameliorates nephropathy in diabetic rats.

This study investigated the hypoglycemic and antioxidant effects of shrimp astaxanthin on the kidney of alloxan-induced diabetic rats. Animals were distributed into four groups of six rats each: a control group (C), a diabetic group (D), a diabetic group supplemented with Astaxanthin (D+As) dissolved in olive oil and a diabetic group supplemented with olive oil (D+OO). In vitro antidiabetic effect was tested in plasma and kidney tissue. The group D of rats showed significant (P < 0.05) increase of glycemia, creatinine, urea and uric acid levels compared to those of the control group (C). Moreover, plasma and kidney malondialdehyde (MDA) and protein carbonyl (PCO) levels for the rats of the group D were significantly increased compared to the control group. Contrariwise, antioxidant enzyme activities, such as catalase (EC 1.11.1.6), superoxide dismutase (EC 1.15.1.1) and non-enzymatic levels of reduced glutathione, were significantly (P < 0.05) decreased in the plasma and kidney of diabetic rats compared to the control ones. The astaxanthin supplementation in rats diet improved the antioxidant enzyme activities and significantly decreased the MDA and PCO levels compared to diabetic rats. Indeed, no significant (P ≥ 0.05) improvement was observed for the fourth group (D+OO) compared to the control group (C). Histological analysis of kidney showed glomerular hypertrophy and tubular dilatation for the diabetic rats. For D+As rats, these histopathological changes were less prominent. Our results suggest that shrimp astaxanthin may play an important role in reduction of oxidative damage and could prevent pathological changes in diabetic rats suggesting promising application of shrimp astaxanthin in diabet treatment.

Antioxidant and protective effect of Curculigo orchioides on liver, pancreas and kidney tissue in alloxan induced diabetic experimental rats

BackgroundThe aim of this study was to investigate the antioxidant activity of Curculigo orchioides in alloxan induced diabetic rats. MethodsDiabetes was induced experimentally in 12-h fasted rats by intraperitoneal injections of alloxan (120 mg/kg b.w.) and C. orchioides (200 mg/kg b.w.) was administered orally for 21 days. ResultsUntreated diabetic rats in comparison with normal rats showed significantly lower mean activities of antioxidant enzymes (superoxide dismutase, catalase, glutathione peroxidase), lower mean levels of non-enzymatic antioxidants (reduced glutathione, vitamin C, vitamin E), elevated mean levels of pancreatic malondialdehyde (MDA), elevated mean activities of serum alanine aminotransferase (ALT), aspartate aminotransferase (AST) and alkaline phosphatase (ALP). Following oral administration of C. orchioides (200 mg/kg b.w./day) to diabetic rats for 21 days exhibited significant improvement of the above parameters. Histopathological studies showed significant changes like cytoplasmic vacuolization of hepatocytes, leukocytic infiltration and edema in the liver and kidney of alloxan-induced diabetic rats. These histopathological abnormalities were found to be normalized after treatment with C. orchioides extract. ConclusionThese results suggest that the methanolic extract C. orchioides enhanced the antioxidant defense against reactive oxygen species produced under hyperglycemic conditions, hence protecting the liver, pancreatic and kidney tissue injuries.

N-acetylcysteine on oxidative damage in diabetic rats

N-acetylcysteine (NAC) is a potent mucolitic agent and also an antioxidant. Its antioxidant action is due to its ability to stimulate reduced glutathione (GSH) synthesis, therefore maintaining intracellular levels. The aim of this study was to evaluate the effects of NAC administered intraperitoneally (i.p.) in a decreasing of oxidative tissue damage in the liver and kidney of alloxan-induced diabetic rats, especially on thiolic groups (nonproteic and proteic groups). Adult male Wistar rats (200–350 g) were used; diabetes was induced accordingly by a single i.p. injection of alloxan monohydrate, and the control group received a similar volume of the vehicle. Lipid peroxidation (LPO) biomarker (malondialdehyde; MDA), δ-ALA-D activity, GSH, superoxide dismutase (SOD), and glutathione peroxidase (GPx) were quantified to assess the oxidative stress. All tests were performed in tissue homogenates. Creatinine, urea, aspartate transaminase, and alanine transaminase were determined by commercial kits, using serum samples. A significant decrease in LPO (i.e., hepatic and renal) and an increase in δ-aminolevulinate dehydratase activity, especially in the renal tissue, were observed. Also, NAC at 75 mg/kg showed more effective restoration of oxidative stress biomarkers than NAC at 25 mg/kg. Our findings suggest that NAC can be used as an antioxidant agent in diabetes, exhibiting modulatory action on the oxidative stress biomarkers analyzed in this work. Moreover, these findings can contribute to others’ research, regarding the utilization of NAC to ALA-D activity restoration in the kidneys.

Flax and Pumpkin seeds mixture ameliorates diabetic nephropathy in rats

This study investigated the hypoglycemic and antioxidant effects of Flax and Pumpkin seeds mixture on the kidney of alloxan-induced diabetic rats. Animals were allocated into three groups of six rats each: a control group (CD), a diabetic group (DD) and diabetic rats fed with Flax and Pumpkin seeds mixture (DMS) group. The DD rats showed a significant increase of glycemia and lipid parameters such as total lipid, total cholesterol and triglycerides levels compared to those of the control group (CD). In addition, plasma and kidney malonaldialdehyde levels (MDA) were significantly increased compared to (CD) group. Antioxidant enzyme activities such as catalase (CAT), superoxide dismutase (SOD) and non-enzymatic levels of reduced glutathione (GSH) significantly decreased in the plasma and kidney of diabetic rats compared to those of controls. Diet supplemented with Flax and Pumpkin seeds mixture ameliorated the antioxidant enzymes activities observed in diabetic rats and significantly decreased MDA levels. Kidney histological sections, showed glomerular hypertrophy and tubular dilatation. In DMS rats, these histopathological changes were less prominent. Our results suggest that Flax and Pumpkin seeds mixture supplemented in diet of diabetic rats may be helpful to prevent diabetes and its complications.

Kidney and Liver Function Parameters in Alloxan-Induced Diabetic Rats Treated with Aloe Barbadensis Juice Extract

Aloe barbadensis juice extract has been reported to possess hypoglycaemic property but the effects of its use on kidney and liver functions in diabetic animals have not been well investigated. This study investigated some biochemical parameters in the liver and kidney of alloxan-induced diabetic rats treated with Aloe barbadensis juice extract. Alloxan-induced diabetic rats were administered orally with Aloe barbadensis juice extract for seven days after which some biochemical indices in the serum, liver and kidney were measured and compared with the control. Serum alkaline phosphatase (ALP), alanine aminotransferase (ALT), aspartate aminotransferase (AST), urea and creatinine of untreated diabetic group and treated diabetic groups were significantly elevated when compared with the normal control group with no significant changes in the levels of the enzymes in the liver and kidney. There were no significant changes (p>0.05) in the serum levels of Na+ and K+ in untreated diabetic group and treated diabetic groups when compared with the normal control rats which are not diabetic. These results suggest that administration of aqueous extract of Aloe barbadensis to diabetic rats did not have any adverse effect on the liver and kidney functions in rats showing that the extract is not toxic to man.

Antioxidant effect of zinc, selenium and their combination on the liver and kidney of alloxan-induced diabetes in rats

Zinc and selenium have been shown to singly act in normalising glycaemia and are also postulated to possess insulin-like functions. Supplementation with their combination in the diets of rats with alloxan-induced diabetes was investigated with the aim of investigating their effects on glucose homeostasis and their antioxidant properties on the liver and kidney of alloxan-induced diabetic rats. Thirty-five rats were randomly assigned to five groups and four groups were made diabetic by the administration of 150 mg/kg body weight of alloxan monohydrate, after which three diabetic groups were fed with diets supplemented with zinc, selenium and a combination of the two. Zinc, selenium and the combination significantly reduced blood glucose concentration, restored hepatic functions, increased the antioxidant status of the diabetic rats and reduced lipid peroxidation in both the hepatic and renal tissues. It was concluded that supplementation with zinc, selenium and the combination facilitated glucose uptake, prevented oxidative stress, reduced lipid peroxidation and preserved hepatic function in diabetes.

Trigonella foenum graecum seed powder protects against histopathological abnormalities in tissues of diabetic rats

Trigonella foenum graecum is a well-known hypoglycemic agent used in traditional Indian medicines. It was previously reported that oral administration of its seed powder for 3 weeks to alloxan diabetic rats stabilized glucose homeostasis and free radical metabolism in liver and kidney. In the present study, we further investigated the effects of 3 weeks alloxan induced diabetes on the histological structure and function of liver and kidney and the protective effect of T. foenum graecum seed powder (TSP) oral administration to the diabetic rats utilizing enzyme analysis and light and transmission electron microscopy. The activity of the enzyme, glutamate dehydrogenase was significantly higher whereas the activity of D-beta-hydroxybutyrate dehydrogenase enzyme was significantly lower in liver and kidney of alloxan-induced diabetic rats. Histopathological studies showed liver degenerative and early nephropathic changes in diabetic rats. Ultrastructure of the diabetic liver revealed a reduction in the rough endoplasmic reticulum and swelling of mitochondria in the hepatocytes. TSP treatment to the diabetic rats effectively prevented the alteration in the activities of the two enzymes and partially prevented the structural abnormalities thus suggesting a protective effect of TSP on the liver and kidney of the diabetic rats. The role of TSP in reversing the diabetic state at the cellular level besides the metabolic normalization further proves its potential as an antidiabetic agent.
