Effects of coffee (Coffea arabica) consumption on the femoral morphology and biomechanics in rats

Abstract Introduction: Coffee consumption has proved to be harmful to osseous tissue integrity, thus, diminishing bone resistance. Considering the great number of individuals consuming coffee daily, therefore, the present study aims to demonstrate the effects of coffee on the femoral morphology and biomechanics resistance in Wistar rats. Methods: Twenty male Wistar rats were chosen for the experiment, divided into two groups (n = 10), as to know, CT (control) group, to which was offered water diet ad libitum; and, CF (coffee) group, to which was offered coffee as liquid diet. After 60 days, the animals had their blood analyzed for serum calcium level, they were euthanized and the right femurs were collected for histological procedure and the left ones were isolated for bone measures and mechanical test. Results: CF group animals do not present malnutrition or dehydration. Femur dimensions, trabecular bone width and cortical width analyses shown to be lower for CF group. Material and structural properties of the femurs of CF group animals demonstrate that this group presents weaker bones than those of CT group. Conclusion: The findings in the present study allow us to confirm that coffee consumption interferes negatively on the material and structural bone properties, diminishes trabecular and cortical bone density, and hence making bones more fragile and likely to fractures. So, due to the great number of individuals consuming coffee daily, it is important to reduce this consume on order to prevent bone trauma.

AbstractIntroduction: The study aimed to investigate the anti-fertility effect of fennel (Foeniculim vulgare Mill) seed extract in male rats.Material and Methods: Forty Wistar rats were divided into five equal groups. The control group received distilled water and the experimental groups were orally administered 1 ml of hydro-alcoholic extract of fennel seed in four doses of 35, 70, 140, and 280 mg/kg/b.w. daily for 60 days. After the last gavage, the rats were anaesthetised and the caudal part of the right epididymis was used for sperm counting. After fixation of the testes, microscopic sections were prepared and histological changes were evaluated.Results: The number of spermatogonia after doses of 140 and 280 mg/kg and Sertoli cells after a dose of 140 mg/kg decreased significantly as compared with the control group (P < 0.05). The number of primary spermatocytes and sperm count decreased significantly in the experimental groups (70, 140, and 280 mg/kg) when compared to the control group (P < 0.05). Furthermore, thickening of the basement membrane, cell apoptosis, and irregular arrangement of the germinal epithelium were observed in the experimental groups.Conclusion: Hydro-alcoholic fennel seed extract at these doses could reduce reproductivity and has anti-fertility activity in male rats.

PURPOSE: To evaluate the development of Walker 256 tumor in male Wistar rats treated with tacrolimus using an experimental kidney tumor model. METHODS: 40 male Wistar rats were divided into four groups: Tumor group (TU) (n=10), Tacrolimus-Tumor group (TT) (n=10), Tacrolimus group (TC) (n=10) and Control group (C) (n=10). Treatment with tacrolimus was performed in groups TT and TC. Under anesthesia, the right kidney of each animal of TU and TT was accessed through a supraumbilical incision and inoculated with a 0.1mL solution containing 2x10(6) tumor cells (Walker 256 carcinosarcoma tumor cells). Group TC was treated with a saline solution. All the animals of groups TC and TT were treated with tacrolimus (5mg/kg/day) by gavage for 15 days. TU group animals received saline by gavage for 15 days. On the 15th postoperative day, all animals were submitted to euthanasia and blood sampling for analysis of serum creatinine (Cr) and blood urea nitrogen (BUN). Abdominal gross examination was performed, the right kidney removed and prepared for histological analysis by hematoxylin-eosin staining. The resulting data were submitted to statistical analysis by ANOVA. RESULTS: Statistical significance was found when comparing creatinine level between groups TU, TT and TC -TT group culminated with a marked increased in creatinine levels (Cr=1.013 ± 0.3028 mg/mL), TU group (Cr=0.5670 ± 0.03536 mg/dL) P=0.00256, TC group (Cr =0.711 ± 0.1653 mg/mL) P= 0.02832. Statistical significance was found when comparing BUN levels in TT group (71.32 ± 17.14 mg/mL), compared with TU group (45.83 ± 5.046 mg/dL), P=0.000318. There were no statistically significant differences between groups TT and TC (61.23 ± 9.503 mg/mL) P=0.7242. Histological analysis showed a poor evolution in TT group with multiple foci of hemorrhage and cortical invasion by the Walker tumor. CONCLUSION: The Tacrolimus-treated group developed a more aggressive tumor and a drug-related nephrotoxic effect.

Caffeine in coffee is suspected to decrease the bone mineral density and increase the risk factor of osteoporosis, however the contents of coffee is not only caffeine. Considering the great number of people consuming coffee daily, therefore, the study is conducted to investigate the effect of robusta coffee consumption on the femoral bone strength in male wistar rats. Thirty male wistar rats were subjected for the study. They were divided into three groups, i.e control group (K) without robusta coffee consumption, treatment group 1 (P1) with robusta coffee consumption of 0,9 mg/gBW, and treatment group 2 (P2) with robusta coffee consumption of 2,7 mg/gBW. After 21 days, the rats were terminated and the right and the left femurs were collected for force bone test. The force bone test of P1 and P2 group demonstrated weaker bones than K group, and there was no difference effect of P1 group compared to P2 group on the femoral bone strength in male wistar rats. It can be concluded that robusta coffee consumption has negative effect on the bone strenght and hence causing bones more fragile, and there was no difference on effect of 0,9 mg/g BW compared to 2,7 mg/g BW.

The use of highly active antiretroviral therapy has proven to be highly effective in the treatment of human immunodeficiency virus 1 (HIV-1) infection. However, its impact on cognition has not been fully explored. This study was designed to assess the impacts of antiretroviral therapy on cognitive function and histoarchitecture of the prefrontal cortex of Wistar rats. Forty adult male Wistar rats weighing 180-200 g were randomly assigned to 4 groups: control, tenofovir, lamivudine and efavirenz (n=10), which received 1 ml distilled water and 6 mg/kg, 6 mg/kg and 12 mg/kg, respectively. Spatial memory scores were assessed using the Y-maze test. Following behavioural studies, the animals were euthanized, and their whole brains harvested. The prefrontal cortex was sectioned and processed for oxidative stress, histological and immunohistochemical analyses. There was a significant decrease in percentage alternation evaluated from the right/wrong decisions scored from the tenofovir and lamivudine groups, compared to the control group (p<0.05). malondialdehyde (MDA) and reduced glutathione (GSH) levels were elevated following lamivudine and tenofovir exposure in the rats’ prefrontal cortices, respectively, compared to control (p<0.05). There were also significant alterations of cortical pyramidal cells in the tenofovir and lamivudine groups. Additionally, marked astrogliosis with increased glial fibrillary acidic protein expression was observed, consistent with the structural alterations, especially in the lamivudine group. Our findings suggest that, of the three highly active antiretroviral therapy (HAART) drugs studied, lamivudine may be a major culprit in the progressive neurological damage and cognitive impairment in HIV-infected individuals on HAART.

PURPOSE: To evaluate the influence of PRP addition on bone repair of circular defects created in irradiated tibiae of rats by histometric analysis. METHODS: Sixty male Wistar rats had the right tibiae irradiated with 30 Gy. After 30 days monocortical defects were created and platelet-rich plasma was applied in 30 rats. In the control group defects were created but not filled. The animals were desanguinated after 4, 7, 14, 21, 56 and 84 days and the tibiae removed for histological processing. RESULTS: There was a tendency in the PRP group to increased bone neoformation from 14-days to 84-days; in the control group increased bone neoformation was not seen after 21 days or later. CONCLUSION: The addition of platelet-rich plasma had a beneficial effect in the initial cellular regeneration period and enhanced bone formation in later periods when compared to control.

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.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.The results of One-Way ANOVA test showed there was no significant difference (p = 0,290) between group of rats without treatment (x̅= 207,50) and group of rats induced by carrageenan (x̅=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 (x̅= 232,50).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.

The aim of this study was to investigate the clinical efficacy of vanadium complexes on triglycerides (TG), total cholesterol (Chol), uric acid (UA), urea (U), and antioxidant parameters: nonenzymatic (FRAP—ferric reducing ability of plasma, and reduced glutathione—GSH) and enzymatic (glutathione peroxidase—GPx, catalase—CAT, and GPx/CAT ratio) activity in the plasma of healthy male Wistar rats. Three vanadium complexes: [VO(bpy)2]SO4⋅2H2O, [VO(4,4′Me2bpy)2]SO4⋅2H2O, and Na[VO(O2)2(bpy)]⋅8H2O are administered by gavage during 5 weeks in two different diets such as control (C) and high fatty (F) diets. Changes of biochemical and antioxidants parameters are measured in plasma. All three vanadium complexes statistically decrease the body mass growth in comparison to the control and fatty diet. In plasma GSH was statistically increased in all vanadium complexes-treated rats from control and fatty group in comparison to only control group. Calculated GPX/CAT ratio was the highest in the control group in comparison to others.

The present investigation was carried out to evaluate the hepatoprotective effect of probiotic fermented milk (FM) containing Lactobacillus rhamnosus GG and Lactobacillus casei strain Shirota, alone as well as in combination with chlorophyllin (CHL) as an antioxidant agent in male Wistar rats administered aflatoxin-B1 (AFB1). AFB1 was injected intraperitoneally at the rate of 450 μg/kg body weight per animal twice a week for 6 weeks, maintaining an equal time interval between the two consecutive AFB1 administrations. A total of 125 male Wistar rats were randomly allocated to five groups, each group having twenty-five animals. Group I was offered FM containing L. rhamnosus GG and L. casei strain Shirota. Group II was administered AFB1 and served as the control group; group III was administered FM-AFB1, in which besides administering AFB1, FM was also offered. Group IV was offered CHL and AFB1, and group V was offered both FM and CHL along with AFB1. The rats were euthanised at the 15th and 25th week of the experiment and examined for the biochemical and hepatopathological profile. A significant reduction in thiobarbituric acid-reactive substances (TBARS) was observed in the FM–CHL–AFB1 group compared with the AFB1 control group. FM alone or in combination with CHL was found to show a significant (P < 0·05) hepatoprotective effect by lowering the levels of TBARS and by enhancing the activities of antioxidant enzymes such as glutathione peroxidase, superoxide dismutase, catalase and glutathione-S-transferase, indicating that probiotic FM alone or in combination with CHL possesses a potent protective effect against AFB1-induced hepatic damage.

Background: The process of wound healing is influenced by various factors such as age, hormones, and wound care. Wound care is done to accelerate wound healing which can be done by various methods, one of them is traditional care. Traditional wound care can use medicinal plants. Rhodomyrtus tomentosa is a medicinal plant that has an antioxidant, anti-inflammatory, antitumor and antibacterial content. Thus this study aims to evaluate the effectiveness of the antiseptic solution of the Rodhomyrtus tomentosa leaf extract on wound healing in male Wistar rats. Method: this research is pure experimental research with post test only control group design. Thirty male white rats were divided into five groups, namely negative control, positive control, Rhodomyrtus tomentosa leaf extract 15%, 30%, and 60%. Rhodomyrtus tomentosa leaf extraction was carried out by maceration method with 70% ethano solvent. The extraction results are divided into 3 concentrations (15%, 30% and 60%). The wound healing process was evaluated by measuring the length of the wound manually from 0 to 10 days in each group. Meanwhile, the number of fibroblast cells was calculated through hematoxylin eosin (HE) staining and observed using an Olympus CX41 microscope with a 10x magnification and objective lens magnification in 3 fields. Result: There was a significant difference in the reduction in wound length (p =< 0,000) between the five experimental groups (Rhodomyrtus tomentosa leaf extract solution 15%, 30% and 60%, negative control and positive control. Solution of rhodomyrtus tomentosa leaf extract accelerated the increase in the number of fibroblasts compared to the negative control group (p = 0.003), but did not make a difference (p = 0.403) with the positive control group. Rhodomyrtus tomentosa leaf extraction solution had the same microscopic effect on the number of fibroblasts with a positive control group given 0.9% NaCl solution. Conclusion: There was a significant difference in the number of fibroblasts between all groups, but no difference in wound healing length.

PURPOSE: To analyze the action of gangliosides in peripheral nerve regeneration in the sciatic nerve of the rat. METHODS: The sample was composed of 96 male Wistar rats. The animals were anaesthetized and, after identification of the anaesthesic plane, an incision was made in the posterior region of the thigh, followed by skin and muscle divulsion. The right sciatic nerve was isolated and compressed for 2 minutes. Continuous suture of the skin was performed. The animals were randomly divided into two groups: the experimental group (EG), which received subcutaneous injection of gangliosides, and the control group (CG), which received saline solution (0.9%) to mimic the effects of drug administration. RESULTS: No differences were observed between the experimental and control groups evaluated on the eighth day of observation. At 15 and 30 days the EG showed an decrease in Schwann cell activity and an apparent improvement in fibre organization; at 60 days, there was a slight presence of Schwann cells in the endoneural space and the fibres were organized, indicating nerve regeneration. At 15 and 30 days, the level of cell reaction in the CG had diminished, but there were many cells with cytoplasm in activity and in mitosis; at 60 days, hyperplastic Schwann cells and mitotic activity were again observed, as well as nerve regeneration, but to a lesser extent than in the EG. CONCLUSION: The administration of exogenous gangliosides seems to improve nerve regeneration.
