Background: The objective of the study was to investigate the effect of fenofibrate on acute and subacute models of inflammation in adult male Wistar rats.Methods: After obtaining clearance from Institutional Animal Ethics Committee, six adult male Wistar rats were allocated to each of the three groups i.e. control, aspirin and fenofibrate. Acute inflammation was studied using carrageenan induced rat paw oedema and the volume displacement due to paw oedema was measured using the plethysmograph. Subacute inflammation was studied using foreign body insertion (cotton pellet and grass pith) models. Dry granuloma weight and histopathological examination of the granuloma were the outcome measures for measuring subacute inflammation. The percentage inhibition of inflammation with aspirin and fenofibrate was calculated in both acute and subacute models. The experiments were conducted according to the guidelines of the Committee for the Purpose of Control and Supervision on Experiments on Animals (CPCSEA). The mean volume displacement obtained with a plethysmograph, the mean dry weight of granuloma and the percentage inhibition with aspirin and fenofibrate were analyzed by one way analysis of variance (ANOVA) using Graph pad prism software.Results: Aspirin and fenofibrate significantly reduced both acute and subacute inflammation (p<0.001). Dunnet’s test showed a significant difference in the study groups when compared to the control. The reduction of inflammation with fenofibrate was comparable to aspirin.Conclusions: Oral fenofibrate showed significant anti-inflammatory activity, which was comparable to aspirin, in both acute as well as sub-acute models of inflammation. This anti-inflammatory effect may benefit atherosclerosis in patients receiving fenofibrate for hyperlipidemia.

Introduction: Monosodium glutamate (MSG) is one of the most widely employed food enhancers. Although the umami compound, controversy persists regarding the effects of MSG intake on body weight. Chronic MSG intake may result in excessive body weight gain and obesity. Consumption of MSG result in organ damage, cardiovascular disease, oxidative stress, and also risk factors for obesity. This study aims to determine the effect of oral MSG on obesity in adult male Wistar rats (Rattus norvegicus).Methods: This true experimental study used the post-test control group design. Twenty-four adult male Wistar rats were randomly divided into four groups: control (received distilled water), Group 1 (MSG 0.378 mg/gr BW), Group 2 (0.756 mg/gr BW) and Group 3 (1.512 mg/gr BW). The obesity parameter was obtained by the Lee index. Kruskal-Wallis test follows by Mann-Whitney test were used to compare the Lee index between groups.Results: Lee’s index mean for each group was 358.4%, 314.1%, 287.8%, and 320.9%, respectively. The Kruskal Wallis test showed a significant difference in the Lee index between groups (p = 0.043). A follow-up test using Mann-Whitney found a significant difference between group 2 and the control group (p = 0.043, p <0.05). The mean of Lee index of group 2 was 70.51% lower than the control group.Conclusion: This study concluded that Lee index was not increased in MSG-treated rats than in the control group after oral MSG intervention for 21 days.

Background: Physical exercise aims to improve or maintain physical fitness. However, excessive physical exercise may cause increase of oxidative stress which leads to cellular injury, including in the proximal tubules of kidney. This research aims to find out the effect of single- and repeated- excessive swimming exercise to the kidney histopathology of male wistar rats (Rattus norvegicus). Methods: This research was an experimental study with complete random and post test only control group design. Twenty seven male wistar rats were divided into three treatment groups: control group, single- excessive swimming exercise group (45 minutes for one day), and repeated- excessive swimming exercise group (45 minutes/day for seven days). In the end of the treatment, the kidney of the rats were taken to be analyzed by using hematoxylin-eosin stain. The mean of proximal tubules injury of kidneys were counted by two observers using blinded method. Data were analyzed by using one way anova test. Result: The analysis showed there was a significant difference in the mean percentage of proximal tubules injury between control group and single swimming group as well as the repeated swimming group (Anova p=0,000), also there was significant difference between the treatment groups (p=0,020). The highest average of proximal tubules injury was in the single swimming group. Conclusion: Single- and repeated- excessive swimming exercise causes the proximal tubules injury of kidney.

Background: The exposure of male individual to environmental toxicant is regarded as a channel that results in reduced sperm counts and infertility. Objective: This study investigated the ameliorative response of Sulforaphane (SFN) on Aluminum trichloride (AlCl3) induced testicular toxicity in adult male Wistar rats. Materials and Methods: A total of 32 adult male Wistar rats (180-200 gm between 8-10 wk) were divided into four groups (n = 8/each). Group A) received distilled water orally as placebo; Group B) received 100 mg/kgbw AlCl3 only orally; Group C) received 100 mg/kgbw AlCl3 and 100 mg/kgbw SFN orally; and Group D) received 100 mg/kgbw SFN only orally. After 28 days of experiment, animals underwent cervical dislocation, blood serum was obtained for analysis, and testes were harvested for biochemical assays, histology, hormonal profile, and sperm characterization. Results: The sperm parameters showed a significant difference within the AlCl3 only group compared with the control and SFN only groups (p = 0.02). However, AlCl3 and SFN co-treatment showed improvement in the motility, viability, and sperm count compared with the AlCl3 only group (p = 0.02). Furthermore, there was a significant decline in the levels of hormones profile and antioxidant status in AlCl3 only group compared to the control and SFN only (p = 0.02). The testicular histoarchitecture of the AlCl3 only group showed shrinkage of seminiferous tubules, spermatogenesis disruption, and empty lumen compared to the control and SFN only groups. Conclusion: The present study revealed the ameliorative response of SFN on AlCl3-induced testicular toxicity on serum hormone profiles, antioxidant status, lipid peroxidation, and histomorphometric analysis through oxidative stress.

Dietary soybean has been shown to have variable effects on the reproductive system of male rodents, non-human primates and humans. These effects can affect subsequent fertility. Soybean intake in men has been advocated due to its protective effect in the prevention of prostate cancer, cardiovascular disease and osteo-arthritis. However, the protection it offers in the prevention of prostatic cancer by altering the levels of male reproductive hormones may lead to infertility. This study aimed at determining the effect of dietary supplementation with soybean on reproductive hormones of male Wistar rats. The study was a randomised controlled trial. Adult male Wistar rats were randomly assigned to a control group and two study groups. The rats in the control group were fed on soy-free diet while rats in Group 1 and Group 2 of the study were fed on 20% and 50% soybean supplemented diet for four weeks. Serum concentration of FSH, LH and Testosterone were estimated. Data obtained was analysed using statistical package for social sciences (SPSS) version 20.0.There was no statistically significant difference (p<0.05) in the level of FSH (p=0.783), LH (p=0.815)and Testosterone (p=0.330) between the study and control groups. Dietary supplementation with of soybean has no effect on the level of FSH, LH and Testosterone in male Wistar rats and therefore may not affect their reproductive function.

Introduction: Anabolic-androgenic steroids (AAS) modify the physiological functioning of the cardiovascular system and have possible effects on the origin of cardiovascular thrombosis. Objective: To determine the impact of the testosterone metabolite on platelet quantification in ORX rats with or without DHT replacement. Material and methods: 24 male 45-day-old Wistar rats underwent orchidectomy with a simple scrotal incision. At 2.5 months of age, the 24 rats were divided into 4 study groups. Half of the 12 male ORX rats received hormone replacement with dihydrotestosterone propionate (DHT) at a 2 mg/kg dose via subcutaneous injection for 7 days and the other half received a physiological solution (0.9% NaCl). The same occurred in the 12 non-ORX males (SHAM). After 7 days of the administration, blood was collected by orbital puncture, and platelet quantification was performed. Results: A significant difference (ANOVA, p < 0.005) was found between the 4 groups. When performing the Dunn Method, a significant difference (p < 0.05) was found in the endogenous administration of DHT between Sham rats and rats ORX + 0.9% NaCl but not with ORX + DHT. Conclusions: DHT induces an increase in platelet quantification inrats Sham and not in ORX rats with DHT, which may affect the increase in platelet quantification.

<p>Liver is an organ with complex metabolism. When the liver is inflamed, cellular immunity will defend against inflammatory agents by stimulating immune cells to produce reactive oxygen species (ROS). Excessive ROS accumulation cause oxydative stress with increased  liver malondialdehyde (MDA) level. Some researches showed that purple sweet potato contain flavonoids (anthocyanins) that functioned as antioxydants. This study aimed to show the prophylactic effect of purple sweet potato extract to the liver MDA level of male Wistar rats induced by carrageenan.</p><p>This study used post-only control group method using 18 male Wistar rats divided into 3 groups: group of rats without treatment, group of rats induced by 0,1 ml of 1% carrageenan by intraplantar injection on day-8, and group of rats given with 872 mg/kgBW of purple sweet potato extract for 7 days and induced by 0,1 ml of 1% carrageenan. In the end of the study, the liver MDA levels were measured by Thio-Barbituric Acid method on each groups.</p><p>The results of One-Way ANOVA test showed there was no significant difference (p = 0,290) between group of rats without treatment (<em>x̅</em>= 207,50) and group of rats induced by carrageenan (<em>x̅</em>=233,17). Then, there is no significant difference (p = 0.978) between group of rats induced by carrageenan and group of rats given with prophylactic purple sweet potato extract and induced by carrageenan (<em>x̅</em>= 232,50).</p><p>The conclusion of this study is giving intraplantar injection of carrageenan can increase liver MDA level insignificantly and giving prophylactic purple sweet potato extract has an effect to decrease the liver MDA level of rats induced by carragenan insignificantly because it contains anthocyanins as antioxidants.</p><p> </p><strong>Keywords: </strong>Liver, <em>Ipomoea batatas</em> L., Malondialdehyde, Anthocyanins
