The aim of this study was to examine whether dexmedetomidine improves acute liver injury in a rat model. Twenty-eight male Wistar albino rats weighing 300–350 g were allocated randomly to four groups. In group 1, normal saline (NS) was injected into the lungs and rats were allowed to breathe spontaneously. In group 2, rats received standard ventilation (SV) in addition to NS. In group 3, hydrochloric acid was injected into the lungs and rats received SV. In group 4, rats received SV and 100 µg/kg intraperitoneal dexmedetomidine before intratracheal HCl instillation. Blood samples and liver tissue specimens were examined by biochemical, histopathological, and immunohistochemical methods. Acute lung injury (ALI) was found to be associated with increased malondialdehyde (MDA), total oxidant activity (TOA), oxidative stress index (OSI), and decreased total antioxidant capacity (TAC). Significantly decreased MDA, TOA, and OSI levels and significantly increased TAC levels were found with dexmedetomidine injection in group 4 (P<0.05). The highest histologic injury scores were detected in group 3. Enhanced hepatic vascular endothelial growth factor (VEGF) expression and reduced CD68 expression were found in dexmedetomidine group compared with the group 3. In conclusion, the presented data provide the first evidence that dexmedetomidine has a protective effect on experimental liver injury induced by ALI.

Using a rat model of laryngeal transplantation, we sought to define the relationships between acute laryngeal rejection grade (RG) and cyclosporin A (CSA) concentration and CSA dosage. Five recipient Lewis rat groups (N = 10 per group) were administered intramuscular CSA doses of 1.0 (group 1), 2.5 (group 2), 5.0 (group 3), 7.5 (group 4), and 10 mg/kg per day (group 5) for 14 days. Immediately before sacrifice, 5 mL of whole blood was obtained to assay CSA trough levels by high-performance liquid chromatography. The specimens were graded microscopically by blinded reviewers by day of RG, 0 to 14 days after transplantation, as described in earlier reports. Despite high intragroup variability in CSA levels, significantly different mean CSA concentrations were achieved among all CSA dosage groups: 1,2,3,4, and 5 (.0001 < p < .02). The mean laryngeal RGs did not test significantly different from each other with groups 3, 4, and 5 (RG, 2.3 ± 1.3 versus 1.9 ± 1.1 versus 1.7 ±0.3, respectively, .2 < p < .6). The RG for group 1 was significantly greater than those for groups 2 through 5 (p < .001), and the group 2 RG was greater (p < .02) than those for groups 3, 4, and 5. Polynomial fitting was used to determine the continuous relationship between each individual specimen's CSA concentration and the RG. Significant pathological allograft rejection correlated with CSA concentrations below 250 ng/mL.

Aluminum (Al) is present daily in our life, the long-term excessive Al intake induces neuroinflammation and cognition retardation. Annona squamosa leaves showed some medicinal activities as anti-inflammatory, antioxidant and antidiabetic drugs. This study was designed to examine the effect of ethanolic and aqueous extracts of annona squamosa leaves against aluminum chloride (AlCl3-induced neuroinflammation in rats. 40 male albino rats were randomly divided into 4 groups, 10 rats each. Group 1; (Control rats), Group 2; (rats received AlCl3 50mg/kg body weight orally (p.o), Group 3; (rats received AlCl3 and annona squamosa leave aqueous extracts (300mg/kg) and Group 4; (rats received AlCl3 and annona squamosa ethanolic extracts (300mg/kg). After two months; blood samples were collected for assessment of serum nuclear factor- ҡβ (NF-ҡβ) and Acetyl cholinesterase (Ach E). The brain of each rat was removed for assessment Brain nitric oxide, reduced glutathione (GSH), malondialdehyde (MDA), superoxide dismutase (SOD), caspase 3 and brain-derived neurotrophic factor (BDNF). AlCl3 increase brain MDA, NO, Ach E activity, NF-ҡβ and caspase 3, significant decreases in GSH, SOD activity and BDNF. Ethanolic or aqueous annona squamosa leaves extracts ameliorate MDA, NO, Ach. E activity, NF-ҡβ and caspase 3 and restore GSH, SOD activity and BDNF to near normal levels in AlCl3 treated rats. Conclusion: Both of ethanolic and aqueous annona squamosa leave extracts protect rat brain against oxidative stress and inflammation induced by AlCl3.

Abstract Background The fruits of Xylopia aethiopica and seeds and leaves of Piper guineense are commonly used as spices. Due to their wide use in nutrition and traditional medicine, there is need to examine the biochemical and histological effects of ethanolic extracts of fruits of Xylopia aethiopica and seeds and leaves of Piper guineense on liver and kidney function in male albino rats. The test animals (groups 2, 3 and 4) received 100 mg/kg each of the corresponding extract for 21 days. Group 1 served as normal control and received a placebo of normal saline. The animals were later fasted overnight, sacrificed and their blood collected through cardiac puncture for biochemical indices. Results AST activity decreased significantly (p < 0.05) in rats of group 2 compared to the normal control; ALP decreased significantly (p < 0.05) in animals of group 3; while ALT increased significantly (p < 0.05) in group 4. The concentrations of urea and potassium showed significant decrease (p < 0.05) in animals of group 3. Creatinine increased significantly (p < 0.05) in group 2. Concentrations of total protein, albumin, globulin, sodium and chlorides in the test animals did not show any significant alteration. WBC count increased significantly (p < 0.05) in rats of group 3 and non-significantly (p > 0.05) in groups 2 and 4. PCV increased significantly in rats of group 4 and non-significantly in groups 2 and 3. RBC count and Hb levels increased non-significantly (p > 0.05) in all the test groups compared to group 1. The histoarchitectural states of the liver and kidneys showed no apparent alteration by the different extracts. Conclusion The extracts have no apparent toxic effect on the liver and kidneys of the experimental rats, although fruits’ extract of Xylopia aethiopica showed possibility of exhibiting mild liver toxicity.

1. Eighty weanling albino rats, five from each of sixteen litters were distributed between five dietary groups in sixteen randomized blocks. Each block was formed from within a litter and each animal in the block received a different diet.2. The main features of the diets were: group 1, 72% sucrose; group 2, 72% uncooked wheat starch; group 3, 72% roll-dried wheat starch; group 4, 36% sucrose and 36% uncooked starch; group 5, 36% sucrose and 36% roll-dried starch.3. The rats were killed after 20 days on the diets and assessed for dental caries. The rats consuming diets containing sucrose (groups 1, 4 and 5) had significantly more caries than animals receiving diets in which starch was the sole carbohydrate. The diet containing roll-dried wheat starch produced significantly more caries than uncooked starch. The mixture of uncooked starch and sucrose was more cariogenic than the mixture of roll-dried starch and sucrose.

Pazopanib is an effective treatment for advanced renal cell carcinoma and soft tissue sarcoma. Besides classical adverse events of this drug class, hepatotoxicity has been described as a frequent side effect. The aim of the present study was to evaluate the effect of pazopanib on the liver in an experimental rat model. Sixteen Wistar albino rats were divided into 3 groups: experimental toxicity was induced with pazopanib (10 mg/kg) administered for 28 days (group 2) or 56 days (group 3) orally by gavage. Group 1 (control group) received only distilled water. Rats in groups 2 and 3 were sacrificed after the collection of blood and tissue samples on the 28th and 56th days, respectively. We found significant differences in bilirubin, alkaline phosphatase, lactate dehydrogenase, glucose, triglyceride, very-low-density lipoprotein, and iron values (p < 0.050 for all) but none in any other parameter (p > 0.050). All rats in the control group had normal histological features; however, none of the rats in groups 2 and 3 showed normal histology. In group 2, we observed mild sinusoidal dilatation, congestion, enlarged Kupffer cells, accumulation of yellow-brown-black pigment in the Kupffer cells and the accumulation of hemosiderin with Prussian blue reaction in the hepatocytes. In group 3, the findings mentioned above were more prominent, and besides these findings focal acinar transformation and macrovesicular steatosis were also observed. In group 3, mild inflammation within the portal areas was observed consisting of lymphocytes, neutrophils, and eosinophils. This study is the first that reports the biochemical and histopathological evaluation of pazopanib-related hepatic toxicity.

Objective. The aim of the study was to investigate the possible protective qualities of resveratrol (RSV) against the side effects of risperidone (RIS) in an experimental model in rat kidneys with histologic and biochemical assessments. Materials and Methods. Experimental procedures were performed on 35 female Sprague Dawley rats. Rats were randomly divided into five groups: control, untreated rats (n=7) were in group 1; group 2 was given 2 mg/kg/day RIS (n=7); group 3 was treated with 2 mg/kg/day RIS and 20 mg/kg/day RSV (n=7); group 4 was treated with 2 mg/kg/day RIS and 40 mg/kg/day RSV (n=7); and group 5 was treated with 2 mg/kg/day RIS and 80 mg/kg/day RSV (n=7). All treatments were administered for two weeks by gavage. On treatment day 15, kidney tissues were removed for analysis. Results. The results showed that RSV treatment reduced weight gain induced by RIS. In addition, RSV increased the total antioxidant status (TAS) and decreased serum creatinine (Cr), blood urea nitrogen (BUN), oxidative stress index (OSI), and total oxidant status (TOS) levels significantly (p<0.05). Conclusion. This study revealed that treatment with RSV might protect kidney tissues against the side effects of RIS. RSV could be an effective course of therapy to enhance therapeutic efficacy.

Amitraz is a pesticide used in agriculture and public health to control insects, weeds, animals, and vectors of disease. Although the use of pesticides is of benefit in general, abuse of the pesticides is harmful due to their potential toxicity to humans and animals. Present study examined the effect of the pesticide on the male reproductive parameters of the male albino rats. 20 rats were grouped into four. Group 1 was control, Group 2 was given low dose Amitraz, Group 3 was median dose, and Group 4 was high dose. The administration was for a period of 21 days. Results showed that Amitraz has dose dependent toxicity effect on the reproductive parameter of the rat. Amitraz is toxic to the reproductive parameters of the albino rat, and could lower sperm concentration, sperm motility, and sperm morphology. By implication, Amitraz is toxic to the reproductive system and could cause infertility in male.
