Mediated Reduction

The majority of liver-related illnesses are caused by occupational and domestic exposure to toxic chemicals like formaldehyde (FA), which is widely common in Africa and the world at large. Hence, measures should be taken to protect humans from its hazardous effects. This study, therefore, examines the protective potential of Ganoderma lucidum (100 mg/kg body weight) on formaldehyde-induced (40%) liver oxido-inflammation in male rats. Male Wistar rats, 150–200 g, were allotted into four groups of 10 animals as follows: Group 1 was orally treated with 1 mg/mL distilled water, Group 2 was exposed to a 40% formaldehyde vapor environment for 30 min per day, Group 3 was orally treated with 100 mg/kg ethanol extract of Ganoderma lucidum, and Group 4 was co-administered formaldehyde and 100 mg/kg ethanol extract of Ganoderma lucidum. Rats were then sacrificed 24 h after administering the last dose of treatment, and the livers were excised. Ganoderma lucidum significantly reversed the formaldehyde-mediated reduction in body and organ weight. Ganoderma lucidum administration significantly prevented oxido-inflammation by reducing the levels of hydrogen peroxide and malondialdehyde and increasing the activity of antioxidant enzymes and glutathione contents, as well as the normal level of nitrite and myeloperoxidase production in FA-treated rats. Additionally, Ganoderma lucidum reversed a large decline in proinflammatory markers in formaldehyde. Furthermore, Ganoderma lucidum restores formaldehyde-induced histological alterations in the liver. Collectively, our results provide valuable information on the protective potential of Ganoderma lucidum in protecting formaldehyde-induced liver oxido-inflammation in male rats.

Echis ocellatus snakebite causes more fatalities than all other African snake species combined. Moringa oleifera reportedly possesses an antivenom property. Therefore, we evaluated the effectiveness of M. oleifera ethanol extract (MOE) against E. ocellatus venom (EOV) toxicities. Thirty male rats were grouped as follows (n = 5): Group 1 (normal control received saline), groups 2 to 6 were administered intraperitoneally, 0.22 mg/kg (LD50) of EOV. Group 2 was left untreated while group 3 to 6 were treated post-envenoming with 0.2 mL of polyvalent antivenom, 200, 400, and 600 mg/kg of MOE respectively. MOE significantly (p<0.05) normalized the altered haematological indices and blood electrolytes profiles. MOE attenuated venom-induced cellular dysfunctions, characterized by a significant increase in NRF2, and concomitant downregulation of increased antioxidant enzymes (SOD and CAT) activities in the serum and heart of the treated rats. MOE normalized the elevated TNF-α and IL-1β in serum and heart tissues. Furthermore, the IgG titre value was significantly (p<0.5) higher in the envenomed untreated group compared to the MOE-treated groups. Hemorrhagic, hemolytic and coagulant activities of the venom were strongly inhibited by the MOE dose, dependently. Lesions noticed on tissues of vital organs of untreated rats were abolished by MOE. Our findings substantiate the effectiveness of MOE as a potential remedy against EOV toxicities.

PURPOSE: To evaluate an experimental animal model to study the abdominal tissue activity considering its interaction with a polypropylene mesh, through the use of one of the optical phenomena of light Laser, the biospeckle. METHODS: Fifty Wistar male rats were divided into four groups: Group 1: ten animals not submitted to surgery; Group 2: ten animals submitted to surgery without polypropylene mesh; Group 3: 20 animals submitted to surgery followed by the mesh placement; Group 4: (sham) with ten animals. None of the animals presented post surgical complications being submitted to the optical tests at the 20th postoperative day. RESULTS: The analysis from the biospeckle tests, comparing the medians and standard deviations with T Student test, indicated that no significative difference was observed on the abdominal wall tissue activity in the four groups considered, with and without polypropylene mesh prosthesis implantation. CONCLUSION: The animal model is viable and the biospeckle open ways for a great number of experiments to be developed in evaluating tissue activity.

PURPOSE: To evaluate modulation in the expression of Transforming growth factor beta2 (TGF-beta2) in short-term colon carcinogenesis. METHODS: 64 male rats was used, comprising 4 groups of 16 animals each: group 1 received Inositol hexaphosphate (IP6) and azoxymethane (AOM); group 2, AOM alone; group 3, IP6 alone; group 4 was used as control. Groups 1 and 3 were given 1% IP6 in drinking water for 6 weeks. AOM was administered subcutaneously at weeks 3 and 4 of the experiment at 20 mg/kg of body weight each week. Immunohistochemical processing was performed with the use of anti-TGF-beta2 primary antibodies in right colon samples and quantitation of TGF-beta2 as percentage of expression, through computer-assisted image processing. RESULTS: mean values of TGF-beta2 expression were 9.0 ± 3.9% for group 4 (control), 12.7 ± 4.0% for group 3 (IP6), 19.3 ± 6.2% for group 2 (AOM), and 13.1 ± 5.3% for group 1 (IP6+AOM). The value of p was calculated as 0.0001 for a 5% or lower significance level. CONCLUSION: the experiment revealed a significant increase in TGF-beta2 expression in right colon with the administration of AOM, and a significant decrease in TGF-beta2 expression when IP6 was administered with AOM.

Introduction: Lead (Pb) is a transition metal and a known male reproductive toxicant that induces its effects mainly through oxidative stress. This study investigated the effects of L-Citrulline (Cit) supplement on reproductive functions and antioxidant activities in Lead acetate treated male rats. Materials and Methods: Twenty  male rats (180-200 g) were grouped into four  and treated as follows; Group 1 (Control), given distilled water, Group 2 was given Pb acetate (2.25mg/kg), Group 3 was co-treated with Pb acetate (2.25mg/kg) and Cit (900mg/kg) and Group 4 was given Cit (900mg/kg) only. All administrations were done orally for thirty days. Caudal sperm, serum hormone levels and testicular antioxidant activities and Nitric oxide levels were evaluated at the end administrations. Results: Results showed decrease (p<0.05) in sperm morphology, count, viability, motility, FSH, LH, Testosterone, Catalase, Nitric Oxide and Super oxide dismutase in Group 2(Pb treated rats), when compared to Group 1(Control).However, in Group 3 (Pb acetate co-administered with Cit) the effect was significantly reversed (p<0.05) compared with Group 2 and significant increase was observed in Group 4 (Cit only group) compared with Group 2. There was an increase (p<0.05) in Malondialdehyde level in Group 2 compared with (Group 1) Control while a significant decrease (p<0.05) was observed in Groups 3 and 4 compared with Group 2. Conclusion: The results of this study suggest that L- Citrulline supplement has ameliorating capacity on the toxic effect of Lead acetate on sperm parameters.

Objective. To investigate the effect of long duration exposure to electromagnetic field from mobile phones on spermatogenesis in rats using 4G-LTE. Methods. Twenty Sprague-Dawley male rats were placed into 4 groups according to the intensity and exposure duration: Group 1 (sham procedure), Group 2 (3 cm distance + 6 h exposure daily), Group 3 (10 cm distance + 18 h exposure daily), and Group 4 (3 cm distance + 18 h exposure daily). After 1 month, we compared sperm parameters and histopathological findings of the testis. Results. The mean spermatid count (×106/ml) was 398.6 in Group 1, 365.40 in Group 2, 354.60 in Group 3, and 298.60 in Group 4 (p=0.041). In the second review, the mean count of spermatogonia in Group 4 (43.00) was significantly lower than in Group 1 (57.00) and Group 2 (53.40) (p<0.001 and p=0.010, resp.). The sum of the germ cell counts was decreased in Group 4 compared to Groups 1, 2, and 3 (p=0.032). The mean Leydig cell count was significantly decreased in Group 4 (p<0.001). Conclusions. The longer exposure duration of electromagnetic field decreased the spermatogenesis. Our findings warrant further investigations on the potential effects of EMF from mobile phones on male fertility.

Citrullus lanatus thumb (Cucurbitaceae) commonly called watermelon is widely consumed in this part of the world as food and medicine. This study was carried out to examine the effect of methanolic extract of watermelon (Citrullus lanatus) rind on prednisolone suppressed immunity in male wistar rats. A total of 20 male wistar rats weighing 150-294g were used in 4 groups with five rats each. Group 1, the control group was given distilled water and feed, Group 2 was given 200 mg/kg body weight of methanolic extract of watermelon rind, Group 3 rats were given 2.5 mg/kg body weight of prednisolone and Group 4 rats were given 2.5 mg/kg body weight of prednisolone and 200 mg/kg body weight of methanolic extract of watermelon rind. Prednisolone and the methanolic extract of watermelon rind were administered orally for a period of 30 days. Blood samples were collected by cardio puncture from the rats for white blood cell (WBC), lymphocyte, and granulocyte and monocyte counts at the end of the experiment.  The data were statistically analysed using one-way ANOVA (Analysis of variance). Data were considered significant at p<0.05. The results obtained showed that methanolic extract of watermelon rind caused a significant increasen in immune function of rats when compared with the control and immune suppressed rats.

Introduction. Evolution of nonalcoholic fatty liver disease (NAFLD) is often accompanied by increased levels of homocysteine, on the other hand hyperhomocysteinemia (HHC) is considered as an independent factor for steatosis and fibrosis of the liver. An important role in regulating of liver functional state has IGF-1 and gas mediator – hydrogen sulfide (H2S), but their role in the pathogenesis NAFLD associated with HHC, is not certain.The aim of the study – to investigate level of insulin-like growth factor-1 (IGF-1) in blood and concentration of H2S in the liver of rats with NAFLD induced by high fat diet (HFD) and its combination with HHC.Methods of the research. The experiment was performed on 56 white male rats. Animals were divided into 4 groups. Group 1 and group 2 received standard diet, group 3 and group 4 received HFD for 60 days. Rats from groups 2 and 4 were injected іntragastrically daily by thiolakton homocysteine in the dose of 100 mg/kg. After experiment the levels of homocysteine and IGF-1 in serum and H2S content in the liver of rats were determined.Results and Discussion. Homocysteine thiolactone or HFD and especially their combination causes a reduction of IGF-1 in serum and H2S content in the liver of rats. Rats with NAFLD associated with HHC had levels of H2S and IGF-1 significantly lower (respectively 22.6 % and 32.2 %) than that of rats with purely NAFLD. The level of homocysteine is inversely correlated with the level of IGF-1 in blood and the level of H2S in the liver (r= -0.68, -0.73, р<0.01). Formation of deficit аntifibrotic mediators (IGF-1 and H2S) may be a factor in the progression NAFLD associated with HHC.Conclusions. 60-day use of HFD or homocysteine thiolactone causes reduction of IGF-1 in serum and H2S content in the liver, but the most significant shortage of mediators is as result of the combination HFD with HHC.

Pregabalin (Lyrica) is an analog of the gamma-aminobutyric acid neurotransmitter,   approved for the treatment of epilepsy, generalized anxiety disorder, neuropathic pain, and fibromyalgia. The possibility for abuse and/or dependence on pregabalin has risen recently. Pregabalin is controlled in many countries including Saudi Arabia. However, unofficial use of this substance is also on the increase. The purpose of this study is to assess the potential neurotoxic effects associated with overdose prolonged pregabalin supplementation. Forty male Wistar rats were divided into Group (1) normal control received distilled water, Group (2) received pregabalin (150mg/kg), Group (3) received pregabalin (300 mg/kg), and Group (4) received pregabalin (600 mg/kg). pregabalin consumption in different doses resulted in significant dysregulation in neurotransmitter release, upsurge oxidative stress markers via enhancing lipid peroxidation and depleting antioxidant markers. Also, pregabalin doses evoked brain tissue inflammation through elevating TNF-α, IL-1β, and MCP-1, Moreover promoted brain tissue apoptosis by activating caspase -3 and suppressed Bcl2. Pregabalin effects on the aforementioned parameters were dose-dependent. These findings could highlight the potential neurotoxic effect of prolonged abuse of pregabalin supplementation through dysregulating brain neurochemical, inflammatory, oxidant/antioxidant, and apoptotic mediators.

Abstract The presented study was planned to determine whether vasoactive intestinal peptide (VIP) could prevent cytokine haemostatic, haematological, and biochemical disturbances in LPS-treated rats. Adult male Wistar rats (weight range: 200-250 g) were used. The study included four groups: group 1 served as a control group (C); animals in group 2 were given intravenously 1.6 mg/100 g of LPS (E. coli, serotype 0.111:B4); in group 3, rats were injected intraperitoneally with 25 ng/kg of VIP; in group 4, the same doses of VIP and LPS were injected simultaneously. Blood samples were collected 6 h after treatments. In endotoxaemic rats, platelet count, fibrinogen, and antithrombin levels were decreased, the activated partial thromboplastin time and prothrombin time were prolonged, and leucopoenia, as well as significant changes in differential leukocyte percentage were demonstrated. In addition, LPS caused statistically significant increases in plasma TNF- , IL-6, and IL-10 levels, and AST, ALT, creatinine, cholesterol, triglyceride concentrations. However, it caused a statistically significant decrease in total protein and albumin levels when compared to control group. The results showed that during endotoxaemia, VIP had moderately therapeutic effect as an antiinflammatory agent, suppressing TNF-α and IL-6, and stimulating IL-10; however, it was not effective against the adverse effect of LPS on investigated haematological and biochemical parameters.
