Redefining the hepatoprotective potential of Javanese turmeric (Curcuma xanthorrhiza) Kombucha towards the diethylnitrosamine-induced hepatotoxicity of mice

PurposeThis research intended the utilization of Javanese turmeric (0.4% w/v) as a kombucha substrate and analysis of its hepatoprotective activity, in comparison against nonfermented Javanese turmeric beverage (JTB) and black tea kombucha.Design/methodology/approachForty-two healthy male Balb/c mice (two- to three-week-old, 20–30 g) were divided into six groups with seven replicates each. The treatments were normal diet, normal diet + Javanese turmeric kombucha (JTK), normal diet + diethylnitrosamine (DEN), DEN + JTB, DEN + JTK, DEN + black tea kombucha. Kombuchas and JTB were given at 0.3 mL/20 g BW/d. DEN was induced intraperitoneally at a dose of 100 mg/kg. Observed biomarkers were blood serum glutamate pyruvate transaminase (SGPT) and serum glutamate oxaloacetate transaminase (SGOT) activity, serum malonaldehyde (MDA), as well as liver histology. Data were analyzed using analysis of variance.FindingsAmong DEN-induced groups, JTK significantly (p < 0.05) diminished the level of blood SGPT, SGOT and serum MDA. JTK also had lower blood SGPT (8.604 ± 2.195 U/L) and serum MDA levels (2.884 ± 0.083 nM/mL) compared to the normal group (8.604 ± 2.195 U/L and 5.050 ± 0.998 nM/mL, respectively). JTK also produced the least damaged liver-cell numbers.Originality/valueJTK demonstrated better hepatoprotective activity compared to JTB.

Gambaran Aktivitas Serum Glutamic Pyruvic Transaminase (SGPT) pada Petugas Batubara di Talang Duku Kabupaten Muaro Jambi

Dust generated from the coal production process is known to have various cytotoxic and carcinogenic contents. Prolonged exposure to coal dust can trigger health problems and affect the function of organs, one of which is the liver. Liver damage is characterized by increased activity of the enzyme Serum Glutamic Pyruvic Transaminase (SGPT), which is an indicator of liver function tests. Groups at risk of exposure to coal dust include people who are in the coal transport traffic area and the coal workers themselves. The study was conducted to describe the activity of Serum Glutamic Pyruvic Transaminase (SGPT) in coal workers at Talang Duku, Muaro Jambi. The research was conducted descriptively with a cross sectional approach. The research was conducted on 30 coal workers at Talang Duku, Muaro Jambi. The Automatic method is used to check SGPT activity using a Chemistry Analyzer. Based on the results of the study most of respondents had normal SGPT activities (73.33%), both in respondents with characteristics aged &lt;40 years (46.67%), working period &lt;5 years (36.66%) and field work division (60%). The results of examining SGPT activity in coal workers at Talang Duku, Muaro Jambi, showed that most of respondents had normal SGPT activity (73.33%) as well as respondents with spesific characteristics.

Immuno-physiological effects of dietary reishi mushroom powder as a source of beta-glucan on Rohu, Labeo rohita challenged with Aeromonas veronii

Beta-glucans have immense potential to stimulate immune modulation in fish by being injected intramuscularly, supplemented with feed or immersion routes of administration. We studied how supplementing Labeo rohita’s diet with reishi mushroom powder containing beta-glucan influenced immunological function. A supplemented diet containing 10% reishi mushroom powder was administered for 120 days. Afterwards, analyses were conducted on different immunological parameters such as antioxidants, respiratory burst, reactive oxygen species (ROS), alternative complement activity, and serum immunoglobulin, which resulted significant increases (p < 0.05; p < 0.01) for the reishi mushroom-fed immune primed L. rohita. Additionally, analyzing various hematological parameters such as erythrocytes and leukocytes count were assessed to elucidate the immunomodulatory effects, indicating positive effects of dietary reishi mushroom powder on overall fish health. Furthermore, the bacterial challenge-test with 1.92 × 104 CFU/ml intramuscular dose of Aeromonas veronii showed enhanced disease-defending system as total serum protein and lysozyme activity levels accelerated significantly (p < 0.01). Nevertheless, reishi mushroom powder contained with beta-glucan ameliorated the stress indicating parameters like acetylcholinesterase (AChE), serum-glutamic pyruvic transaminase (SGPT) and serum-glutamic oxaloacetic transaminase (SGOT) enzyme activities results suggested the fish’s physiology was unaffected. Therefore, the results indicated that adding dietary reishi mushroom as a source of beta-glucan could significantly boost the immune responses in Rohu.

Exploration of the role of bound polyphenols on tea residues dietary fiber improving diabetic hepatorenal injury and metabolic disorders

Consumption of tea residues dietary fiber (TRDF) contributed to the relief of hyperglycemia symptoms in type 2 diabetes (T2D). Given the properties of TRDF abundant in bound polyphenols, the research intended to evaluate the effect of the presence or absence of bound polyphenols in TRDF on the improvement of diabetic complications (liver and kidney injury, metabolic disorders) in T2D rats induced by high-fat diet and streptozocin injection. Our results revealed that the presence of bound polyphenols in TRDF was remarkably beneficial for the amelioration of liver and kidney damage caused by T2D, which was supported by significant differences in activities of serum glutamic oxaloacetic transaminase (AST) and glutamic-pyruvic transaminase (ALT), contents of inflammatory factors in liver and kidney, the levels of kidney oxidative stress, as well as histopathological status between TRDF and bound polyphenols removed-TRDF (TRDF-DF) groups. In addition, metabolomic analysis revealed that TRDF interventions could increase the levels of metabolites such as S-Adenosylmethionine, L-Homophenylalanine and Riboflavin, as well as differ in the regulation of the metabolic pathways including arachidonic acid metabolism and cysteine and methionine metabolism as compared to TRDF-DF without bound polyphenols. These results suggested that bound polyphenols ensured the health-promoting effects for T2D complications of TRDF.

The efficacy of bentonite and zeolite in reducing aflatoxin B1 toxicity on production performance and intestinal and hepatic health of broiler chickens

This research aimed to assess the influences of bentonite (BN) and zeolite (ZE) on reducing toxic influences of aflatoxin B1 (AFB1) in broilers by examining growth performance, carcase characteristics, serum indices, ileum morphology, apparent nutrient digestibility, and liver AFB1 residues. In total, 360 11-d-old straight-run broilers (Ross 308) were randomly allocated into 6 dietary treatments, with 10 replications of 6 birds each, in a 20-d experiment. The treatments were as follows: standard basal diet (negative control, NC); NC + 0.25 mg/kg AFB1 (positive control, PC); NC + 0.4% BN; NC + 0.4% ZE; PC + 0.4% BN; PC + 0.4% ZE. Compared to the NC diet, feeding the PC diet decreased daily feed intake (DFI) during the grower and overall periods (p < .01), reduced daily weight gain (DWG) and production efficiency factor (PEF) and increased feed conversion ratio (FCR) during grower, finisher, and overall periods (p < .001), lowered breast meat yield (p < .01), diminished dressing percentage, serum concentrations of total protein (TP), albumin (ALB), glucose (GLU), total antioxidant capacity (T-AOC), and total superoxide dismutase (T-SOD), villus height (VH), villus surface area (VSA), apparent digestibility of crude protein (CP) and ether extract (EE), apparent metabolisable energy (AME), and nitrogen-corrected AME (AMEn) (p < .001), and raised proportional liver weight, serum activities of glutamic oxaloacetic transaminase (GOT) and glutamate pyruvate transaminase (GPT), and residues of AFB1 in the liver (p < .001). Compared to the PC diet, feeding the PC + 0.4% BN or PC + 0.4% ZE diets increased DWG and PEF and decreased FCR during finisher and overall periods, raised dressing percentage, serum levels of TP, GLU, T-AOC, and T-SOD, apparent CP digestibility, and reduced proportional liver weight and AFB1 residues in the liver (p < .001). Moreover, feeding the PC + 0.4% BN diet increased VH, VSA, apparent EE digestibility, AME, and AMEn, and decreased serum GOT and GPT activities when compared to the PC diet (p < .001). Whereas, feeding the PC + 0.4% ZE diet increased DFI during all experimental periods (p < .05) and DWG and PEF during the grower period (p < .001) as compared to the PC diet. To conclude, our findings demonstrate that dietary addition of 4 g/kg BN can deliver a better safeguard against the adverse influences of AFB1 in broiler chickens.

Effects of Partial and Full Dietary Substitution of Fish Meal and Soybean Meal by Sunflower Meal on Growth Performance, Feed Consumption, Body Indices, Serum Chemistry and Intestine Morphology of Oreochromis niloticus

A 03-months feeding experiment was designed to study the effects of partial and full dietary substitution of fish meal and soybean meal with sunflower meal (SFM) on growth performance, feed consumption, body indices, serum chemistry and intestine morphology of Oreochromis niloticus. Five isonitrogenous and isocaloric dietary treatments: T1, T2, T3, T4 and T5 were prepared by supplementing SFM at 0%, 25%, 50%, 75% and 100% respectively and fed to fish (4 ± 0.07 g) in triplicates. The growth performance and feed consumption in O. niloticus was significantly (p &lt; 0.05) improved and body indices was significantly reduced in groups fed with T1 (control), T2 and T3 however, survival rate was remained unaffected among all dietary treatments. Significantly increased whole-body protein, serum total protein and albumin content was found in groups fed with T1 (control), T2 and T3, compared to T4 and T5 groups whereas, whole-body lipid content was significantly elevated in T5 group. In contrast, serum glutamic-pyruvic transaminase (SGPT) and glutamic-oxalacetic transaminase (SGOT) activity was significantly elevated in groups fed with T4 and T5. Additionally, serum triglycerides and cholesterol level were significantly increased in group T1 compared to other groups however, glucose and creatinine were not affected by dietary treatments. Uran`s pooled score for intestinal histology was significantly increased in SFM supplemented treatments as compared to control group. In conclusion, replacement of SBM with SFM up to 50% is possible without negative impacts on growth performance and health status of O. niloticus.

Primary stress response and biochemical profile of Labeo rohita (Hamilton, 1822) experimentally parasitized with Argulus bengalensis (Ramakrishna, 1951).

Argulosis is a major problem that causes huge economic loss in aquaculture. In a microcosm, an infested condition was developed upon Labeo rohita with 100 ± 10 adult morphs of Argulus bengalensis per fish. Primary stress response and biochemical profiles of the host were evaluated to underscore the pathogenicity of the parasites. Significant alterations in biochemical parameters were monitored at four different post-infestation time points: days 1, 3, 6 and 9. The overall increasing trends of both plasma cortisol and plasma epinephrine indicate parasite-induced primary stress response among experimental fish. The study revealed a hyperglycaemic trend throughout the infestation period, which has been correlated with hypoxia-associated glycogenolysis. Decreasing level of plasma cholesterol has also been correlated with the development of anaemia and subsequent hypoxia among the infested fish. Plasma protein of the experimental fish initially increases as an outcome of the immediate innate immune response against Argulus infestation, whereas the decrease in plasma protein at the later period of infestation results from less-dietary protein intake due to loss of appetite, reduced digestibility and metabolic proteolysis. Plasma Na+ concentration showed an overall decreasing trend throughout the infestation period, which may be due to excess production of catecholamine under stress. Nonetheless, plasma K+ concentration showed an increasing trend up to day 6 of infestation, and thereafter the value declined to the control level. Plasma ionic imbalances reflect changes in cell permeability under tissue hypoxia and the wounds produced on the skin for intensive feeding activity of the parasites. Both serum glutamate oxaloacetate transaminase and serum glutamate pyruvate transaminase activities were significantly elevated throughout the infestation period, which indicates excess synthesis or release of those enzymes from the damaged cells of the tissues. Activities of some renal, hepatic and branchial antioxidant enzymes, viz., superoxide dismutase, catalase and glutathione-S-transferase, increased in the infested fish. The fact is explained as an effort of the fish for gaining adaptive adjustment to neutralize the oxidative stress generated under the parasitic stress. The overall experimental result points towards the generation of potential stress upon host fish by this branchiuran parasite. The biochemical alterations of the fish under argulosis are centred around the two stress-sensitive hormones, cortisol and epinephrine. The outcome of the study will be the important physiological determinants in adopting a suitable control measure as well as assessing the nutritional value of the fish under diseased condition.

Protective Effect of Date Pits on Growth Performance, Carcass Traits, Blood Indices, Intestinal Morphology, Nutrient Digestibility, and Hepatic Aflatoxin Residues of Aflatoxin B1-Exposed Broilers

This research aimed to assess the influence of date pits (DP) on reducing toxic influences of aflatoxin B1 (AFB1) in broilers by examining the growth performance, carcass characteristics, serum indices, ileum morphology, apparent nutrient digestibility, and liver AFB1 residues. In total, 360 11-day-old straight-run broilers (Ross 308) were randomly allocated into 6 dietary treatments, with 10 replications of 6 birds each, in a 20-day experiment. The treatments were as follows: standard basal diet (negative control, NC); NC + 0.25 mg/kg AFB1 (positive control, PC); NC + 2% DP; NC + 4% DP; PC + 2% DP; PC + 4% DP. Compared to the NC diet, feeding the PC diet decreased the daily feed intake (DFI) during the grower and overall periods (p &lt; 0.01); reduced the daily weight gain (DWG) and production efficiency factor (PEF); increased the feed conversion ratio (FCR) during all experimental periods (p &lt; 0.001); diminished the dressing percentage, breast meat yield, serum concentrations of total protein (TP), albumin (ALB), glucose (GLU), total antioxidant capacity (T-AOC), total superoxide dismutase (T-SOD), villus height (VH), villus surface area (VSA), apparent digestibility of crude protein (CP) and ether extract (EE), apparent metabolizable energy (AME), and nitrogen-corrected AME (AMEn) (p &lt; 0.001); and raised the proportional liver weight, serum activities of glutamic oxaloacetic transaminase (GOT) and glutamate pyruvate transaminase (GPT), and residues of AFB1 in the liver (p &lt; 0.001). Compared to the PC diet, feeding the PC + 2% DP or PC + 4% DP diets increased the DWG during finisher and overall periods, PEF during the finisher period, serum levels of TP, GLU, T-AOC, and T-SOD, VH, and apparent digestibility of CP and EE, AME, and AMEn, and decreased FCR during all experimental periods and AFB1 residues in the liver (p &lt; 0.001). Moreover, feeding the PC + 4% DP diet increased the DWG during the grower period, PEF during the overall period, dressing percentage, serum ALB level, and VSA, and decreased the proportional liver weight and serum GOT and GPT activities when compared to the PC diet (p &lt; 0.001). To conclude, our findings demonstrate that a dietary addition of 4% DP can deliver a better safeguard against the adverse influences of AFB1 in broiler chickens.

Safety assessment of the indigenous probiotic strain Lactiplantibacillus plantarum subsp. plantarum Kita-3 using Sprague-Dawley rats as a model.

Lactiplantibacillus plantarum subsp. plantarum Kita-3 is a candidate probiotic from Halloumi cheese produced by Mazaraat Artisan Cheese, Yogyakarta, Indonesia. This study evaluated the safety of consuming a high dose of L. plantarum subsp. plantarum Kita-3 in Sprague-Dawley rats for 28 days. Eighteen male rats were randomly divided into three groups, such as the control group, the skim milk group, and the probiotic group. Feed intake and body weight were monitored, and blood samples, organs (kidneys, spleen, and liver), and the colon were dissected. Organ weight, hematological parameters, serum glutamic oxaloacetic transaminase (SGOT), and serum glutamic pyruvic transaminase (SGPT) concentrations, as well as intestinal morphology of the rats, were measured. Microbial analyses were carried out on the digesta, feces, blood, organs, and colon. The results showed that consumption of L. plantarum did not negatively affect general health, organ weight, hematological parameters, SGOT and SGPT activities, or intestinal morphology. The number of L. plantarum in the feces of rats increased significantly, indicating survival of the bacterium in the gastrointestinal tract. The bacteria in the blood, organs, and colon of all groups were identified using repetitive-polymerase chain reaction with the BOXA1R primers and further by 16S rRNA gene sequencing analysis, which revealed that they were not identical to L. plantarum subsp. plantarum Kita-3. Thus, this strain did not translocate to the blood or organs of rats. Therefore, L. plantarum subsp. plantarum Kita-3 is likely to be safe for human consumption.

EFFICACY OF TRITICUM AESTIVUM (WHEATGRASS) AGAINST ARSENIC INDUCED HEPATIC DAMAGES

Objective: Arsenic is a metalloid element that is one of the most important global environmental toxicants and is found in both organic and inorganic forms. The present study was designed to find out the preventive role of Triticum aestivum against arsenic-induced oxidative stress in the liver of Swiss albino mice&#x0D; Methods: The protective role of T. aestivum (Wheatgrass) against arsenic-induced hepatic damages was investigated in adult Swiss albino mice. The animals were divided in to four groups: (i) Control group – only vehicle (double distilled water), (ii) T. aestivum treated group-20 ml/kg body weight (b.wt.), orally (iii) NaAsO2 treated group- 4.0 mg/kg b.wt., and orally (iv) combination group – T. aestivum leaves extract (20 ml/kg b.wt.) and NaAsO2 (4.0 mg/kg/b.wt.). Bodyweight and liver weight were measured in the process. Activities of marker enzymes such as alkaline phosphatase (ALP), Glutamic oxaloacetic transaminase, and glutamic pyruvic transaminase were measured in serum. Activities of lipid peroxidation (LPO), glutathione (GSH), and Lactate dehydrogenase (LDH) were measured in the liver.&#x0D; Results: The results indicated that arsenic intoxication caused a decrease in b.wt. and liver weight. Arsenic intoxication significantly increased hepatic LPO, Serum Glutamate Oxaloacetate Transaminase (SGOT), and Serum Glutamate Pyruvate Transaminase (SGPT) activities whereas significantly decreased hepatic GSH, hepatic LDH, and serum ALP activities. Combined treatment of T. aestivum and NaAsO2 showed: (i) An increase in body and liver weight, (ii) a significant decrease in LPO, SGOT, and SGPT activities, (iii) an elevation in GSH content, LDH, and serum ALP activities, as compared to NaAsO2 treated group.&#x0D; Conclusion: Thus, T. aestivum was found to be protective against arsenic-induced hepatic damages.

Hepatoprotective effect of Pandanus odoratissimus seed extracts on paracetamol-induced rats

Context Pandanus odoratissimus Linn. (Pandanaceae) seed extract is known to have antioxidant activities. However, the potential hepatoprotective effect is still unclear. Objective To investigate the hepatoprotection aspect of P. odoratissimus methanol extract towards paracetamol-induced rats. Materials and methods Thirty male Sprague–Dawley rats were randomly divided into six equal groups: one group served as the healthy control and five groups with hepatotoxicity (hepatotoxic control and 4 treatment groups). The oral treatment of paracetamol-induced hepatotoxicity of 3 g/kg using three different concentrations of P. odoratissimus (300, 600 and 900 mg/kg), and silymarin (200 mg/kg) groups were administered once a day for 14 days. Enzyme activities and protein levels in serum were determined in rats at the end of the treatments. The histopathology of rat livers was observed under an electron microscope with 10× magnification. Results Pandanus odoratissimus significantly decreased the serum glutamic-oxaloacetic transaminase (SGOT), serum glutamic pyruvic transaminase (SGPT), alkaline phosphatase (ALP) and γ-glutamyl transferase (GGT) activities in induced-paracetamol rat serum (p < 0.05). Moreover, P. odoratissimus significantly decreased total bilirubin and direct bilirubin levels (p < 0.05). It significantly blocked the decline of serum albumin and protein levels (p < 0.05). Histopathological changes amplified paracetamol-induced liver damage and the hepatoprotective effect of P. odoratissimus in the liver. Discussion and conclusions Pandanus odoratissimus improved the hepatoprotective effect in a concentration-dependent manner by reducing related hepatic enzyme and protein markers, suggesting as a useful agent in hepatotoxicity treatment, and it can be generalized to a broader study population in different hepatotoxic animal models.

Evaluation of toxicological responses and promising biomarkers of topmouth gudgeon (Pseudorasbora parva) exposed to fipronil at environmentally relevant levels.

Fipronil is an insecticide commonly used in agriculture. We report here on the sublethal and sub-chronic effects of fipronil on non-target topmouth gudgeon (Pseudorasbora parva) at environmentally relevant levels. The results showed that fipronil did not cause significant changes in brain acetylcholinesterase activities, glutathione S-transferase (GST) activities in the intestine, and GST, glutamic pyruvic transaminase (GPT), and glutamic oxaloacetic transaminase (GOT) activities in the liver tissues at environmentally relevant levels for 96-h exposure. In the further test for a 12-day exposure, dose-dependent responses of the serum GPT and GOT activities were observed in all treated groups with sublethal concentrations of fipronil. Furthermore, fipronil could reduce the liver mitochondrial membrane fluidity of P. parva, especially with high concentration of fipronil at high temperature. The results suggest that serum GPT and GOT in P. parva might be useful biomarkers for effects of fipronil exposure at environmentally relevant level, and reducing fluidity of liver mitochondrial membrane may be one toxic mechanism of fipronil.

Protective effect of ethanolic extract of Hygrophila auriculata seeds in cyproterone acetate-induced sexual dysfunction in male albino rats.

Male infertility has become a global concern. Different conventional medicines with some side effects generally are used for the management of male infertility. To search out the potent aphrodisiac agent without side effect, an approach has been taken to prevent the cyproterone acetate (CPA)-treated male infertility by ethanolic extract of seed of Hygrophila auriculata in albino rat. CPA is used for the treatment of prostate cancer. It has anti-androgenic properties and suppresses the spermatogenesis process. Count, motility and viability of spermatozoa, number of hypo-osmotic tail swelled spermatozoa and serum testosterone level were significantly decreased in CPA-treated rat. CPA also caused significant diminution of activities of superoxide dismutase, catalase, peroxidase and elevation of malondialdehyde and conjugated dienes levels. All parameters were significantly restored after the treatment of H.auriculata extract to the CPA-treated rats. Histological study revealed significant rectification of seminiferous tubular diameter and spermatogenic cells in extract-treated group. Body weight, organo-somatic indices, serum glutamic oxaloacetic transaminase and serum glutamic pyruvic transaminase activities were significantly recovered towards control in H.auriculata-treated group. It is concluded that ethanolic extract of H.auriculata has androgenic and antioxidant properties that can improve male infertility without metabolic toxicity.

This study aimed to investigate the effect of inclusion of caraway seeds sieving (CSS) as feed additives at different levels in rabbits’ rations. The experiment was carried out at privet farm in Giza, Egypt. Thirty-six unsexed Rex rabbits breed aged 5-6 weeks with average weight of 687.25±2.75g were randomly assigned into four equal groups, (9 rabbits each) in 3 replicates and housed in galvanized wire cages (30 x 35 x 40 cm). The experimental rabbits’ groups received one of the tested rations. The feeding period was extended for 56 days throughout the summer season of year 2018. The experimental rations were classified as the following: First group was fed the basal ration (R1) served as a control group, meanwhile, the other three experimental groups were received rations supplemented with 2, 4 and 6% of CSS for (R 2, R3, and R4), respectively. The results showed that, chemical composition of the experimental rations was similar in their contents of CP that ranged from 20.35 to 21.40% and differed in their contents of gross energy that ranged from 4190 to 4308 kcal/ kg DM. Incorporation of CSS in the rations increasing ether extract content of tested rations comparing to control, meanwhile it decreased the contents of crude fiber and cell-wall constituents. Rabbits received 4% CSS containing ration recorded the highest (P>0.05) digestion coefficient values of (OM, CP, CF, NFE, NDF, ADF and cellulose) and nutritive values (TDN, DCP and DE). Dietary rations had no significant effect (P>0.05) on blood serum total protein; albumin; globulin; albumin: globulin ratio; total lipids; triglycerides, alkaline phosphatase, LDH and HDL. Also, serum Glutamic Oxaloacetic Transaminase (GOT) and Glutamic Pyruvic Transaminase (GPT) activities were not affected by CSS. Serum concentration of creatinine (mg/dl) was significantly higher than control. Means of pH, NH3-N and TVFA's in caecum was no affected by levels of CSS. Rations of (CSS) significant increase of final live body weight (FLBW), total body weight gain (TBWG) and average daily gain (ADG) comparing to control. ADG ranged 19.32 to 31.27 gm, respectively among the four groups. The best value of ADG was recorded by rabbits received 4% CSS containing ration. Also, feed conversion that expressed as (g feed intake of DM, CP, DCP and TDN/ g gain) and digestible energy (kcal/ g. gain) was improved. Net revenue and relative economic efficiency were increased, meanwhile, feed cost/ kg live body weight gain was decreased. It could be mentioned that incorporation 4% caraway seeds sieving in rabbit rations realized the best results in terms of growth performance with a positive effect on digestion coefficients and occurred high net revenue.

The beneficial effect of vitamin E supplementation on zinc status, carbohydrate metabolism, transaminases and alkaline phosphatase activities in alloxan-diabetic rats fed on zinc deficiency diet

The aim of this study was to investigate the beneficial effect of vitamin E supplementation on zinc deficiency in experimentaldiabetes. Male alloxan-diabetic Wistar, albino rats of 10 weeks of age were divided into three groups. The first groupreceived a diet containing 54 mg zinc/kg (adequate zinc group, AZ), the second group received a diet containing 1mg zinc/kg(zinc deficient group, ZD), and the third group received a diet containing 1mg zinc/kg supplemented with vitamin E(500mg/kg diet) (ZD+VE). Body weight gain and food intake of all rats were recorded regularly over a period of four weeks.On day 28, after overnight fasting, animals were killed and blood glucose, serum cholesterol, serum triglycerides, serumprotein, serum urea, serum zinc, femur zinc, pancreatic zinc, testis zinc, liver glutathione concentrations and serum glutamicoxalic transaminase (GOT), serum glutamic pyruvic transaminase (GPT) and serum alkaline phosphatase activities weredetermined on blood and tissue samples. Body weight gain of zinc deficient diabetic animals at the end of four weeks ofdietary manipulation was significantly lower than that of zinc adequate diabetic animals. Dietary zinc intake significantlyincreased blood glucose, serum cholesterol, serum triglycerides, and serum urea of zinc deficient diabetic rats. In contrast,serum zinc, femur zinc, pancreatic zinc, serum protein and liver glutathione levels were lower. The consumption of zincdeficient diet led also to an increase in serum GOT, GPT coupled with a decrease in serum alkaline phosphatase. Vitamin Eameliorated all the previous parameters.

HEPATOPROTECTIVE EFFECT OF 50% ETHANOL EXTRACT OF SEAGRASS RHIZOME (CYMODOCEA ROTUNDATA) AGAINST LIVER TISSUES IN PARACETAMOL-INDUCED RATS

Objective: This study aimed to determine the hepatoprotective effect of 50% ethanol extract of seagrass rhizome in terms of serum glutamicoxaloacetic transaminase (SGOT) and serum glutamic pyruvic transaminase (SGPT) activities in paracetamol-induced rat plasma.Methods: This study included 28 male, white rats randomly divided into seven groups. Groups I and II represented the normal control and controlgroups, respectively, administered with 280 mg/kg BW of rhizome extract. Group III represented the negative control group induced by a suspensionof paracetamol (2g/kg BW). Group IV represented a positive control group administered with Hepa-Q® at a dosage of 150 mg/kg BW. Groups V, VI,and VII were administered with seagrass rhizome extract at doses of 140, 280, and 560 mg/kg BW, respectively, before paracetamol induction. Thetest material was orally administered for 17 days. On days 12–17, the rats were induced with paracetamol through the same route. On day 18, bloodsampling was performed followed by SGOT and SGPT plasma measurements.Results: Our results revealed that seagrass rhizome extracts could significantly decrease SGPT and SGOT levels in paracetamol-induced rats (p&lt;0.05)compared with those in the negative control group.Conclusion: Thus, seagrass rhizome extracts possess the potential for development as a hepatoprotective agent.

Pengaruh Pemberian Ekstrak Alga Merah (gracilaria verrucosa) terhadap Aktivitas SGPT pada Tikus Putih (rattus norvegicus) Jantan Galur Wistar yang Diinduksi Parasetamol Dosis Tinggi

Background: Administration of high dose paracetamol may increase the metabolic pathways that produce N-acetyl-p-benzoquinonimin (NAPQI). NAPQI is a reactive substance, resulting liver tissue damage and increase SGPT activity. Red algae extract contains flavonoids that act as antioxidants.Objectives: This research aimed to determine the effect of red algae (Gracilaria verrucosa) extract to the activity of serum glutamic pyruvic transaminase (SGPT) in male Wistar rats (Rattus norvegicus) induced by high dose paracetamol.Methodology: This research used 24 animal of Male Wistar rats. These rats were divided into 3 groups: 1) group of rats fed with standard food; 2) group of rats given paracetamol 1750 mg/kg on day 10; and 3) group of rats given red algae extract 200 mg/kg/day on day 1-11 and paracetamol 1750mg/kg on day 10. On day 11, all rats were sacrificed and SGPT activities were measured by spectrophotometry method.Result: Mann-Whitney test results showed significant difference (p = 0.021) between SGPT activity of group of rats fed with standard food (=81.95±10.103 U/L) and group of rats induced by high dose paracetamol (=97.06±11.19 U/L). Furthermore, there was significant difference (p = 0.016) between SGPT activity of group of rats induced by high dose paracetamol (=97.06±11.19 U/L) and group of rats induced by high doses of paracetamol and fed with red algae extract (=82.73±11.233 U/L).Conclusion: The conclusion of this research showed that high dose paracetamol significantly increased SGPT activity and red algae extract significantly decreased SGPT activity because it contains flavonoids that act as antioxidants.

Triazinone herbicide metribuzin induced acute liver injury: A study of animal model

Objective: To evaluate the acute toxicity effect of metribuzin at low dose on liver of mother rabbits and its fetus. Methods: Pregnant female rabbits Oryctolagus cuniculus were divided into three groups (n=5). The first group of non-treated pregnancy rabbits served as control; the second group of pregnancy rabbits were treated with 1/100 LD50 of metribuzin and the third group of pregnancy rabbits were treated with 1/50 LD50 of metribuzin. Metribuzin was added in their drinking water for 60 d before and during pregnancy. Levels of liver malondialdehyde, liver glutathione S transferase, serum glutamic oxalacetic transaminase and serum glutamic- pyruvic transaminase were determined. Liver reduced glutathione level was also determined by a colorimetric method. And hepatic homogenate was analyzed by HPLC analysis to determine the existence of traces of metribuzin. Results: Results revealed a significant increase in level of liver malondialdehyde, glutathione S transferase, serum glutamic oxalacetic transaminase and serum glutamic-pyruvic transaminase activities in mother and fetuses rabbits of both metribuzin treatment groups as compared to the control group. However the level of reduced glutathione was decreased in mother and fetuses rabbits of both groups treated with metribuzin compared to control group. Also, the results obtained by HPLC technique showed the presence of trace metribuzin in liver cells of mothers and fetuses rabbits of the both metribuzin treated groups. Conclusions: In conclusion, this study shows that exposure to metribuzin at low concentrations causes a acute toxicity in liver of mother rabbits and its fetus, also the trace of the metribuzin detected in the liver is the origin of possible malformation of the fetuses or abortion of the rabbits.
