Abstract Pesticides are considered the main source of environmental pollution and causing severe hazardous effects on humans and livestock. Imidacloprid (IC) and hexaflumuron (HFM) are broadly used insecticides for crop protection in the world. Some studies discussed IC toxicity in rats, but the toxicity of HFM doesn’t elucidate yet. So that, the current study aimed to investigate the pathogenesis and the mechanistic way of both IC and HFM induced hepatorenal toxicity in rats with comprehensive insight into its molecular mechanism. 21 male Wistar albino rats were divided into 3 groups as the following: group (1), normal saline; group (2), receiving IC; and group (3), receiving HFM. All the following materials were orally administered every day for 28 days. At the end, all rats were euthanized to collect blood and organ samples (liver and kidneys). The results revealed behavioral alterations in walking, body tension, alertness, and head movement as well as a decrease in body weight of rats receiving either IC or HFM. In addition to increasing the levels of MDA with decreasing GHS levels in liver and kidney homogenates. Both liver and kidney tissues showed extensive histopathological alterations associated with increasing the serum levels of ALT, AST, urea, and creatinine as well as reduction in total proteins, albumin, and globulin levels. Furthermore, there was upregulation of m-RNA levels of caspase-3, JNK, and HO-1 genes with strong positive reaction of caspase-3, TNF-ὰ and NF-KB proteins in both liver and kidneys of rats receiving either IC or HFM compared with the control group. We can conclude that both IC and HFM induced oxidative hepatorenal damage via ROS overproduction that activate NF-KB signaling pathways and mitochondrial and JNK dependent apoptosis pathway.

Abstract Pesticides are viewed as a major wellspring of ecological contamination and causing serious risky consequences for people and animals. Imidacloprid (IM) and hexaflumuron (HFM) are extensively utilized insect poisons for crop assurance on the planet. A few investigations examined IM harmfulness in rodents, but its exact mechanism hasn’t been mentioned previously as well as the toxicity of HFM doesn’t elucidate yet. For this reason, the present study was designed to explore the mechanism of each IM and HFM–evoked rat liver and kidney toxicity and to understand its molecular mechanism. 21 male Wistar albino rats were divided into 3 groups, as follows: group (1), normal saline; group (2), IM; and group (3), HFM. Both insecticides were orally administered every day for 28 days at a dose equal to 1/10 LD50 from the active ingredient. After 28 days postdosing, rats were anesthetized to collect blood samples then euthanized to collect liver and kidney tissue specimens. The results showed marked changes in walking, body tension, alertness, and head movement with a significant reduction in rats’ body weight in both IM and HFM receiving groups. Significant increases in MDA levels and decrease of GHS levels were recorded in liver and kidney homogenates of either IM or HFM groups. Liver and kidney tissues obtained from both pesticide receiving groups showed extensive histopathological alterations with a significant increase in the serum levels of ALT, AST, urea, and creatinine and a decrease in total proteins, albumin, and globulin levels. In addition, there was upregulation of the transcript levels of casp-3, JNK, and HO-1 genes with strong immunopositivity of casp-3, TNF-ὰ, and NF-KB protein expressions in the liver and kidneys of rats receiving either IM or HFM compared with the control group. In all studied parameters, HFM caused hepatorenal toxicity more than those induced by IM. We can conclude that each IM and HFM provoked liver and kidneys damage through overproduction of ROS, activation of NF-KB signaling pathways and mitochondrial/JNK-dependent apoptosis pathway.

AbstractBackgroundCisplatin-induced acute liver and kidney injuries are serious problems in cancer patients during treatment of solid tumours.ObjectiveThis study sought to investigate possible protective effect of ethanolic fruit extract ofMethodsThirty male albino rats (150–200 g) were divided into five groups (n=6) and treated as follows: group 1: vehicle (10 mL/kg, p.o.; normal control); group 2: vehicle (10 mL/kg); groups 3–5: CC (100, 200 or 400 mg/kg, p.o.), respectively, for 10 days. Cisplatin (7.5 mg/kg; i.p.) was administered on the 7th day to animals in groups (2–5) 1 h after pretreatment. The animals were euthanized on day 10 for haematological, biochemical and histological analysis.ResultsCisplatin induced a significant increase in the serum levels of ALT, ALP, creatinine and blood urea nitrogen indicative of hepato-renal injury. More so, cisplatin caused marked increase in granulocyte, lymphocyte and platelets counts which were ameliorated by CC (100–400 mg/kg) treatment. In addition, cisplatin induced marked increase in MDA and nitrite levels coupled with deficits in glutathione, catalase and superoxide dismutase activities which were attenuated by CC administration.ConclusionsThis study showed that

ABSTRACT Objective: to evaluate the effects of blocking the regulation of vascular tone on the ischemia and reperfusion syndrome in rats through the use of lidocaine in the postconditioning technique. Methods: we randomized 35 rats into seven groups of five animals: Group 1- Control; Group 2- Ischemia and Reperfusion; Group 3- Ischemia, Reperfusion and Saline; Group 4- Ischemic Postconditioning; Group 5- Ischemic Postconditioning and Saline; Group 6- Lidocaine; Group 7- Ischemic Postconditioning and Lidocaine. Except for the control group, all the others were submitted to renal ischemia for 30 minutes. In postconditioning groups, we performed ischemia and reperfusion cycles of five minutes each, applied right after the main ischemia. In saline and lidocaine groups, we instilled the substances at a rate of two drops per minute. To compare the groups, we measured serum levels of urea and creatinine and also held renal histopathology. Results: The postconditioning and postconditioning + lidocaine groups showed a decrease in urea and creatinine values. The lidocaine group showed only a reduction in creatinine values. In histopathology, only the groups submitted to ischemic postconditioning had decreased degree of tubular necrosis. Conclusion: Lidocaine did not block the effects of postconditioning on renal ischemia reperfusion syndrome, and conferred better glomerular protection when applied in conjunction with ischemic postconditioning.

Objective: The main objective of this study was to evaluate the antidiarrheal activity of Bunim bulbocastanum seeds extracts, to exploit the medicinal use of plant in the traditional system of medicine scientifically. Methods: The adult Wistar albino rats were divided in four groups, i.e. Group M1 (control group) receiving normal saline, group M2 (test group 1) receiving the 250 mg/kg Bunium bulbocastanum extract, group M2 (test group 2) receiving the 500 mg/kg Bunium bulbocastanum extract and group M4 (reference) receiving 3 mg/kg P. O Loperamide. Each group of mice with a bodyweight of 1 ml/100 g received castor oil. Mice were sacrificed and the distance traveled by the charcoal meal and the total length of the intestine was then measured. The peristaltic index and percentage of inhibition were calculated by using the formula. Results: It was found that in the castor oil-induced intestinal transit method extract produced a significant (p<0.0001) dose-dependent reduction in the distance traveled by charcoal meal comparable to the control peak effect was at the dose of 500 mg/kg (PI=12.06±3.38). Likewise, in the diarrheal dropping test, Bunium bulbocastanum extract causes a significant (p<0.05) dose-dependent reduction in the number of wet feces i.e. the mean wet of feces was decreased from 2.3±0.44 gm to 1.28±0.36 gm i.e. significantly different from that elicited by control (0.80±0.17 gm) (p=0.0081). However, there were no significant differences in inhibition at a dose of 250 mg/kg of extract. Conclusion: This study demonstrated that the crude methanol extract from B. bulbocastanum seeds possesses significant antidiarrheal property and the presence of various secondary metabolites. This justified the antidiarrheal use of plant in the traditional system of medicine.

Beryllium induced neurotoxicity and therapeutic potential of naringenin had been explored for the first time in rats. For this purpose, 30 female albino rats were divided into six groups. Group 1 served as control, group 2 was naringenin per se and rest of the four groups were exposed to beryllium nitrate (1mg/kg, i.p.) daily for 28 days. Naringenin was orally administered in group 4, 5 and 6 at different doses (10, 20 and 30 mg/kg) for 5 days after 28 days of neurotoxicity. All the animals were subjected to elevate plus maze, light dark chamber and rotarod experiments. Beryllium exposure decreased body weight, time spent and number of entries in open arm, increased time spent in close arms as compared to control in elevated plus maze whereas decreased % time spent in bright arena, number of entries in bright arena and increased % time spent in the dark arena in light and dark chamber; decreased motar coordination and balance skills on rotarod. Naringenin showed therapeutic potential and brought the studied variables more towards control at 20 mg/kg dose. It can thus, be concluded that naringenin may be an agent of therapeutic choice in case of beryllium induced behavioral alterations.

PURPOSE: To study the effects of progesterone on an experimental colitis model. METHODS: Wistar albino rats were treated subcutaneously with 2mg/kg once a day during seven days Colitis was induced by intrarectal administration of 5mg trinitrobenzene sulfonic acid (TNBS). Disease activities, macroscopic and microscopic scores were evaluated. To determine the response provoked by progesterone we measured Colonic malondialdehyde (MDA), TNF alfa, IL-6 and Nitric oxide (NO) levels in addition to the MPO (Myeloperoxidase) and caspase-3 activities. RESULTS: Progesterone ameliorated significantly the macroscopic and microscopic scores. TNBS-induced colitis significantly increased the colonic MDA levels and caspase-3 activities in group 2 in comparison to the control group. The results of the study revealed a decline in MDA, NO, IL6 and TNF-α levels in the colon tissue and in blood due to progesterone therapy in group 3 when compared to the group 2, a significant improvement. Progesterone treatment was associated with decreased MDA, MPO, TNF alfa and caspase-3 activity. CONCLUSION: Progesterone therapy decreased oxidative damage in the colonic mucosa.

AIM: Antibiotics have a great risk property, for this reason, the present work aimed to study the toxic effect of cefotaxime on histological examination of liver and kidney tissues as well as to detect the protecting role of Vitamin C. METHODS: Thirty-two male adult albino rats were divided into four groups each with (eight animals) as following: Group (1): As control group and they injected with normal saline. Group (2): They were injected with 200 mg/kg B.W. of cefotaxime. Group (3): They were injected with Vitamin C in dose 100 mg/kg B.W. 1 h before they inject with 200 mg/kg B.W. of cefotaxime. Group (4): It was given Vitamin C in dose of 100 mg/kg B.W. Animals in all groups were injected intraperitoneally as single daily dose for 14 consecutive days. RESULTS: Results of cefotaxime treated group revealed that a significant liver tissue changes as hepatocytic vacuolation, necrosis, cholestasis with sinusoidal congestion, and dilatation also induced a histopathological change in the kidney including tubular epithelial degeneration, cast formation in renal tubules, inflammatory cells infiltration in the interstitium, and few glomeruli showed eosinophilic material deposition at the wall of bowman capsule. Adding Vitamin C to third group induces amelioration in the histological features of liver and kidney seen in Group (2) while group of Vitamin C only showed a histological picture similar to control group. CONCLUSION: From this study, we can conclude that Vitamin C has important hepato-renal protective effect.

One of the major obstacles that males with diabetes may confront is subfertility or infertility. Thus, the present study investigated the effect of co-administration of metformin and zinc (Zn) on the testes of streptozotocin-induced diabetic rats. Male albino rats were randomly divided into 4 groups: control group; untreated diabetic group; diabetic + metformin group, in which diabetic rats were treated orally with metformin (250 mg/kg) once daily for 4 weeks; and diabetic + metformin + Zn group, in which diabetic rats were treated orally with metformin in combination with Zn (10 mg/kg) once daily for 4 weeks. Concomitant administration of metformin and Zn produced a significant decrease in serum levels of glucose and insulin and testicular levels of malondialdehyde and tumor necrosis factor α. Additionally, there was a significant increase in serum levels of Zn, testosterone, and follicle-stimulating hormone, as well as testicular total antioxidant capacity and anti-apoptotic protein Bcl-2, when compared with both the diabetic and metformin-treated diabetic groups. Moreover, co-administration of Zn and metformin significantly improved testicular histopathology, with a significant reduction in percent area of collagen fibers and nuclear factor kappa B (p65) immunoreactivity and a significant increase in seminiferous tubule diameter and connexin 43 immunoreactivity as compared with the diabetic and metformin-treated diabetic groups. In conclusion, the combination of Zn and metformin was an efficacious and safe alternative treatment, as it had superior antihyperglycemic efficacy and provided additional benefits over metformin alone in rats with type 2 diabetes.

Aim: In cyclosporin-A (CsA)-induced toxicity, oxidative stress has been implicated as a potential responsible mechanism. Therefore, we aimed to investigate the protective role of erdosteine against CsA-induced nephrotoxicity in terms of tissue oxidant/antioxidant parameters and light microscopy in rats. Materials and methods: Wistar albino rats were randomly separated into four groups. Group 1 rats treated with sodium chloride served as the control, group 2 rats were treated with CsA, group 3 with CsA plus erdosteine, and group 4 with erdosteine alone. Animals were killed and blood samples were analyzed for blood urea nitrogen (BUN), serum creatinine (Cr), uric acid (UA), total protein (TP), and albumin (ALB) levels. Kidney sections were analyzed for malondialdehyde (MDA) and nitric oxide (NO) levels and superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GSH-Px) activities, as well as for histopathological changes. Results: In the CsA group, MDA, GSH-Px, BUN, and Cr levels were increased. The TP and ALB levels were decreased. These changes had been improved by erdosteine administration. Other biochemical parameters did not show any significant change. Conclusion: These results indicate that erdosteine produces a protective mechanism against CsA-induced nephrotoxicity and suggest a role of oxidative stress in pathogenesis.

Abstract Background: Pregabalin (PGB) used as analgesic in treatment of neurogenic pains of chronic diseases, is considered as one of the most abused anti-epileptic drugs worldwide and it has been proved that it induces addictive behaviors. The present histopathological study aimed to identify the effect of PGB administration on cerebral cortex and cerebellar cortex, in both acute and chronic toxicity. Seventy-two male and non-pregnant female adult albino rats’ 6- to 8-week-old divided into 3 main groups of 24 rats each were studied. Group 1 represented the control group and group 2 represented the acute toxicity group, in which rats were given a single dose of PGB (5000 mg/kg) orally by gavage and after 24 hours, rats were sacrificed and examined. Group 3 represented the chronic toxicity group; were given PGB 500 mg/kg orally by gavage for 12 weeks, after which rats were sacrificed and examined. Result: Cerebral cortex tissue of acute toxicity group displayed astrocytosis and dystrophic changes, while in chronic group showed degeneration, necrosis and cellular infiltrates. The cerebellum of chronic groups showed degeneration and shrunken of Purkinje cells. Conclusion: Acute and chronic intoxication with pregabalin adversely altered the structure of cerebral cortex and cerebellum.
