Background and aims: The purpose of this study was to examine the effect of 2 months of endurance training (ET) along with ginger consumption on the serum levels of liver enzymes (ALT and AST), enzymatic activity of superoxide dismutase, and malondialdehyde (MDA) in liver tissue in male Wistar rats. Material and Methods: 40 adult male Wistar rats were randomly divided into 5 groups according to the weight as follows: control (n=8), sham (n=8), ET (n=8), ginger (n=8), and ET + ginger (n=8). The training protocol was an ET program on a treadmill for two months (5 days a week). Besides standard water and food, in groups using the supplement, 100 mg of ginger solution per kg body weight of the rats was injected three days a week. Then, 48 hours after the last training session and after 8 hours of fasting, blood and tissue samples were collected over night and the serum levels of liver enzymes (ALT and AST), MDA level of the liver tissue, and activity of the liver superoxide dismutase (SOD) were measured. One-way ANOVA and Tukey post-hoc test were used for data analysis. Results: The results showed that after 8 weeks, the activity of liver SOD in ET group (131.7±18.6, P=0.001) and ET + Ginger group (130.2±31.3, P=0.001) significantly increased in comparison with the control group (83.8±14.9). Moreover, liver MDA levels in the ET group (0.38±0.08, P=0.008) and ET + Ginger group (0.37±0.09, P=0.013) significantly increased in comparison with the control group (0.25.0±03). However, 8 weeks of ET coupled with ginger consumption had no effects on the serum levels of AST and ALT (P>0.05). Furthermore, ginger had no effect on MDA level and enzymatic activity of SOD (P>0.05). Conclusion: This study does not support the protective effects of ginger on the reduction of liver enzymes levels and improvement of the antioxidant status

High Intensity Interval

Background: Nowadays, one of the widely used training methods is high-intensity interval training (HIIT). In addition, researchers have stated that long-term, high-intensity training is associated with the production of free radicals in the body. Free radicals also damage liver cells, resulting in increased liver enzymes. Objectives: The objective of this study was to investigate the effect of HIIT, compared to high-intensity continuous training (HICT), on damage and antioxidant indices of the liver in male Wistar rats. Methods: Twenty-two adult male rats were randomly divided into three groups of control (n = 6), HIIT (n = 8), and HICT (n = 8). Training protocols included HIIT and HICT on a treadmill for eight weeks (five days in a week). Standard water and food were provided for rats ad libitum. Forty-eight hours after the last training session, blood and tissue samples were collected, and serum enzymes were measured by the methods recommended by the International Federation of Clinical Chemistry and Laboratory Medicine (IFCC) method. The level of enzyme activity of superoxide dismutase in the liver tissue was measured by Randox Commercial Kit (Cat. No. SD 126). One-way analysis of variance (ANOVA) and Tukey’s post hoc tests were used to analyze the data. Results: The results showed that eight weeks of HIIT and HICT had no effect on the alanine aminotransferase (ALT) level (P = 0.14), but eight weeks of HIIT significantly decreased the serum aspartate aminotransferase (AST) level compared to the control group (P = 0.04). The level of liver superoxide dismutase (SOD) enzyme activity significantly increased in the HIIT and HICT groups compared to the control group (P = 0.001). HICT also led to a significant increase in the SOD level compared to HIIT (P = 0.03). Conclusions: The research results suggested that eight weeks of HIIT led to a significant reduction in serum AST levels, and HIIT had a lower effect on the increased SOD activity in liver tissue compared to HICT. It might be stated that HIIT is safer than HICT, and it has fewer destructive effects on liver tissue.

Non-alcoholic fatty liver induces many complications to the liver tissue and also serum related parameters. Medicinal plants are the safe therapeutic strategy for the treatment of diseases. In this regards, the present study was conducted to evaluate the effect of Tribulus terrestris L. (Zygophyllales: Zygophyllaceae) extract on non-alcoholic fatty liver in rats. In this experimental study, thirty male Wistar rats were divided into five groups (n = 6). Animals in experimental groups were received high fructose diet (70%) (HDF) daily alone or in combined with daily intraperitoneal injection of 500, 700 and 1,000 mg/kg extract of T. terrestris. Control group of rats was feed with standard chow. The serum levels of biomarkers of liver and serum lipid profiles were assessed, also histopathological examination of liver tissue done. Data were analyzed using One-way ANOVA method followed by Tukey’s post-hoc multiple comparison test and P < 0.05 was considered statistically significant. There were significant improvements for biomarkers of liver tissue (P < 0.05) and serum lipid profiles (P < 0.01) in the HFD-fed rats that were treated with T. terrestris extract compare to HFD-fed group. In addition, accumulation of lipids in hepatocytes was significantly reduced in the HFD-fed + extract administrated groups in comparison to HFD-fed rats (P < 0.01). T. terrestris extract has protective effects against non-alcoholic fatty liver by changing biomarkers of liver tissue, serum lipid profiles and histopathological anomalies of liver tissue, to normal range.

Honey is consumed as food and also used in the treatments of ailment. However, honey of various types exhibit varying properties. Their therapeutic effects are determined by whether the honey is multifloral or monofloral, and also on the variety of nectars the honey is derived from. Manuka and Tualang types of honey were observed to possess anti-ulcer effects. However, no such report is available for University of Ilorin honey. This study therefore aimed to determine the gastroprotective effects of University of Ilorin honey in Wistar rats using two laboratory models for inducing ulcer (HCl/Ethanol and Indomethacin). Twenty rats each were assigned to four groups for each model of ulcer. The rats were treated for 12 days with the administration of distilled water (control), cimetidine (100 mg/kg b.w.) and University of Ilorin honey (250 mg/kg b.w. in one group and 1000 mg/kg b.w in another group). The rats were fasted for 24 hours after the last treatment. Then, the ulcerogens were given orally. After four hours, the rats were sacrificed, gastric juice was collected and the stomachs were examined for ulceration. The results revealed that pre-treatment with University of Ilorin honey reduced gastric index from 6.80±0.20 (1000 mg/kg b.w. to 2.40±0.24 (control) P<0.05 and 7.20±0.37 (1000 mg/kg b.w.) to 3.20±0.37 (control) P<0.05 in HCl/Ethanol and indomethacin induced ulcer models respectively. There was no significant difference in ulcer index between the cimetidine administered rats and the honey administered group (1000 mg/kg bw.), but the honey group (250 mg/kg bw.) was less effective than the cimetidine group in the models used. Also, there were no changes in gastric acidity in all the groups compared with the control group. In conclusion, the results showed that University of Ilorin honey has protective effect on the gastrointestinal tract which is not due to alteration of gastric acidity.

ABSTRACT: Flaxseed is considered a functional food with several health benefits. However, because of its high phytoestrogen content, flaxseed influences hormone metabolism and affects the gonadal biomorphology. In this study, computerized histomorphometry was used to evaluate seminiferous and epididymal tubules, considering the different regions of the epididymis (head, body and tail) of rats subjected to a prolonged diet of flaxseed. Young adult male Wistar rats (n=20) were divided into 2 groups during their lactation period: Control Group (CG), fed casein-based meals and Flaxseed Group (FG), fed a 25% flaxseed meal. After 250 days of continuous ingestion, the animals were euthanized and a blood sample was collected. The testicles and epididymis were removed and fixed in buffered formalin solution. The samples were subjected to routine histological paraffin techniques and stained with hematoxilin and eosin. Immunostaining was performed using an antivimentin antibody for Sertoli cell identification. For morphometry, images of the slides were scanned and analyzed using Image J to determine the epithelial height, tubular and luminal diameter and tubular and luminal area. In the hormonal evaluation, FG had a higher serum concentration of estrogen (P=0.001), but no change was observed in the concentration of testosterone. The morphometric assay of seminiferous tubules and epididymal regions revealed no significant differences between the analyzed groups. Similarly, Sertoli cell quantification showed no significant differences in the FG (P=0.98). These results revealed that the continuous and prolonged intake of 25% flaxseed meals from gestation to 250 days of age, even with a significant increase in serum levels of estradiol, does not exert adverse effects on the testicular and epididymal structure or on the cells participating in the spermatogenesis of rats.

Safety evaluation of Waltheria indica Linn. root was carried out in Wistar rats. Twenty adult male Wistar rats were randomly divided into four groups (n=5); A–D. Group A served as control group while groups B, C and D were administered with 200, 400 and 800 mg/Kg of crude ethanol extract of Waltheria indica Linn. root. After 28 days of administration, the rats were sacrificed and blood samples were collected and serum prepared. Haematological and biochemical parameters, as well as serum electrolyte were determined according to standard procedures. The 200 mg/Kg of Waltheria indica Linn. root caused the highest percentage increase in body weight. The kidney was also significantly increased at 400 mg/kg. The total WBC and lymphocytes counts were significantly increased at 400 mg/kg. The serum levels of ALT and chloride were significantly increased at 800 mg/kg. Waltheria indica Linn. root also caused hepatic necrosis and renal tubular degeneration in Wistar rats. Therefore, Waltheria indica Linn. root should be used with caution especially at higher dose despite its therapeutic potentials.

ABSTRACT Non-alcoholic fatty liver can be triggered by used cooking oil consumption due to the formation of free radicals and the accumulation of fatty acids in the body. Astaxanthin is a powerful antioxidant that may be able to inhibit the pathogenesis of fatty liver. This study aims to determine the effect of astaxanthin in inhibiting fatty liver (steatosis) and levels of Gamma-Glutamyltransferase (GGT) in male Wistar rats given used cooking oil. An experimental study with Post-test Only Control Group Design was conducted on 36 male Wistar rats aged 3.5-4 months with an approximate bodyweight of 200-210 grams divided randomly into 2 groups. The control group was given 0.42 ml of used cooking oil + 0.5 ml of distilled water, and the treatment group was given 0.42 ml of used cooking oil + 0.2 mg of astaxanthin each day for 14 days. On day 15, blood tests and hepatic histopathology were performed to check  GGT serum levels and steatosis. The comparative test was conducted to compare the results of the control and treatment groups. The results showed that the mean steatosis and GGT levels in the treatment group were significantly lower than the control group. It can be concluded that giving astaxanthin can inhibit fatty liver (steatosis) and increase GGT serum levels in male Wistar rats given used cooking oil.   Keywords: Astaxanthin, Fatty liver, Gamma-glutamyltransferase, Used cooking oil

Over the years, research works on the different liver enzymes has proven to be very helpful to man. This study evaluates the protective effects of turmeric on the liver enzymes of metronidazole-treated adult male wistar rats. With previous researches, metronidazole has been found to exert some negative effects on some organs of the body like the testis, kidney etc but the turmeric on its own part, has been found to have no side effects with a host of beneficial functions such as its anti-oxidant and antimicrobial effect amongst a host of other functions. In this study, twenty wistar rats with weight range of between 165-180g were assigned into four groups A, B, C and D of 5 each. The experimental groups A, B and C were orally administered 200mg of metronidazole, 400mg of metronidazole and 400mg of metronidazole as well as 400mg of turmeric respectively for duration of twenty-eight days while the group D served as control and were orally administered water and feed only. Twenty four hours after the last administration, the animals were anaesthetized under chloroform inhalation and dissected for organ collection. Blood for serum preparation was collected into sterile plain tubes and stored in the refrigerator for analysis. Serum samples from the bloods were analyzed for liver enzymes activities using randox kit method. The study revealed that turmeric helped reduced the effects of metronidazole on the serum activities of ALT, AST and ALP on the liver. This present study suggests that metronidazole could have negative effects on the liver and so advises that turmeric be added when on metronidazole administration.

Our aim was to investigate the influence of microgravity on the sensitivity of the skin to mechanical stimulation, epidermal thickness, peripheral nerve density in the upper dermis, and serum levels of a stress marker in a rat hindlimb suspension (HS) model. Thirty 8-week-old male Wistar rats were randomly divided into 3 groups: HS, n=10; sham HS, n=10; control, n=10. The suspension system was attached to rat tails in both the HS and sham-HS groups, but the hindlimbs were suspended only in the HS group. The HS and sham-HS groups were treated for 4 weeks. In behavioral tests using von-Frey filaments (n=5 in each group), mechanical hypersensitivity developed in the HS and sham HS groups. Serum corticosterone levels increased significantly in the HS and sham HS groups compared to the control group, and no changes in epidermal thickness or peripheral nerve density were observed immediately after the removal of HS (n=5 in each group). These data indicated that the mechanical hypersensitivity observed in the HS group was not caused by microgravity or inactivity, but rather by restraint stress. We suggest that microgravity does not affect skin sensitivity and histology in these animals.

The high incidence of alcoholic poisoning in Indonesia is caused by the use of methanol as a surrogate ingredient of nonconforming alcohol. The product of methanol metabolism is toxic to the liver. Ranitidine has been studied as an antidote to reduce the effect of methanol toxicity. The present study aimed to assess the effect of ranitidine administration on the liver damage of Wistar rats with acute methanol intoxication. This research was an experimental study with randomized and posttest-only control group design. A total of 24 male Wistar rats divided into four groups, each consisting of six Rats. The control group (K0) served as a reference normal value. The control group (K1) was intoxicated with methanol 7 g/kg body weight (b.w.) through rat gavage tube. Treatment groups were intoxicated with methanol and 15 minutes after that, Ranitidine (30 mg/kg b.w. (P1) or 60 mg/kg b.w. (P2)) was given intraperitoneally. Ranitidine administration was proven to protect the liver tissue from damage due to methanol intoxication as was indicated from the histopathological examination. Ranitidine with dose 60 mg/kg b.w. is better in reducing the degree of liver tissue damage in acute methanol intoxication rats.
