This study aimed to analyse the protective effects of quercetin on the toxicity of cadmium (Cd) using metabonomics techniques. Sixty male Sprague–Dawley rats were randomly divided into six groups ( n = 10): control group (C), low-dose quercetin-treated group (Q1; 10 mg/kg bw/day), high-dose quercetin-treated group (Q2; 50 mg/kg bw/day), Cd-treated group (D; 4.89 mg/kg bw/day), low-dose quercetin plus Cd-treated group (DQ1) and high-dose quercetin plus Cd-treated group (DQ2). The rats continuously received quercetin and Cd via gavage and drinking water for 12 weeks, respectively. The rat urine samples were collected for metabonomics analysis. Finally, 10 metabolites were identified via the metabonomics profiles of the rat urine samples. Compared with the control group, the intensities of taurine, phosphocreatine, l-carnitine and uric acid were significantly decreased ( p < 0.01) and those of LysoPC (18: 2 (9Z, 12Z)), guanidinosuccinic acid, dopamine, 2,5,7,8-tetramethyl-2(2′-carboxyethyl)-6-hydroxychroman and allantoic acid were significantly increased ( p < 0.01) in the Cd-treated group. However, the intensities of the aforementioned metabolites had restorative changes in the high-dose quercetin plus Cd-treated groups unlike those in Cd-treated group ( p < 0.01 or p < 0.05). Results indicated that quercetin exerts protective effects on Cd-induced toxicity by regulating energy and lipid metabolism, enhancing the antioxidant defence system and protecting liver and kidney function and so on.

The main purpose of this study was to examine the effect of flavonoids from Lotus leaf (FFL) on exercise-induced oxidant stress in mice. 32 mice were randomly divided into 4 groups: control group, FLL low dose treated group, FLL middle dose treated group and FLL high dose treated group. The control group was given distilled water and the treated groups were given different doses of FLL (50, 100, 150 mg/kg) by gavage once a day for 28 days. 28 day later, mice were made to swim until being exhausted, and exhaustive swimming time, malondialdehyde (MDA) levels, superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) activities in muscle were measured. The data showed that that FFL increase the exhaustive swimming time and could elevate the exercise tolerance, as well as decrease the MDA levels, increase SOD and GSH-Px activities in muscle of mice. These results indicated that FFL has a protective effect against exercise-induced oxidative stress.

Exposure to drugs and toxic chemicals, during late pregnancy, is a common occurrence in childbearing women. Some studies have reported that more than 90% of pregnant women use at least 1 prescription; of this, 60% used more than one. Another study indicated that 80% of the consumed drugs were not prescribed, and of this figure, 95% were “over-the-counter” drugs. Acetaminophen, the safest of all over-the-counter drugs, has been reported to induce fetal liver necrosis in man and animals and to have abortifacient and embryocidal action in mice. This study examines the degree to which acetaminophen affects the neonatal liver and kidney, when a fatty diet is simultaneously fed to the mother during late pregnancy.Timed Swiss Webster female mice were gavaged during late pregnancy (days 16-19) with fat suspended acetaminophen at a high dose, HD = 84.50 mg/kg, and a low dose, LD = 42.25 mg/kg; a control group received fat alone.

(1) Background: The endothelial glycocalyx is a primary target during the early phase of sepsis. We previously reported a newly developed recombinant non-fucosylated antithrombin has protective effects in vitro. We further evaluated the effects of this recombinant antithrombin on the glycocalyx damage in an animal model of sepsis. (2) Methods: Following endotoxin injection, in Wistar rats, circulating levels of hyaluronan, syndecan-1 and other biomarkers were evaluated in low-dose or high-dose recombinant antithrombin-treated animals and a control group (n = 7 per group). Leukocyte adhesion and blood flow were evaluated with intravital microscopy. The glycocalyx was also examined using side-stream dark-field imaging. (3) Results: The activation of coagulation was inhibited by recombinant antithrombin, leukocyte adhesion was significantly decreased, and flow was better maintained in the high-dose group (both p < 0.05). Circulating levels of syndecan-1 (p < 0.01, high-dose group) and hyaluronan (p < 0.05, low-dose group; p < 0.01, high-dose group) were significantly reduced by recombinant antithrombin treatment. Increases in lactate and decreases in albumin levels were significantly attenuated in the high-dose group (p < 0.05, respectively). The glycocalyx thickness was reduced over time in control animals, but the derangement was attenuated and microvascular perfusion was better maintained in the high-dose group recombinant antithrombin group (p < 0.05). (4) Conclusions: Recombinant antithrombin maintained vascular integrity and the microcirculation by preserving the glycocalyx in this sepsis model, effects that were more prominent with high-dose therapy.

Background. To investigate the effect of subacute intravenous administration AgNP (silver nanoparticles, 10 nm) and AuNP (gold nanoparticles, 12.8 nm) and AgNP/AuNP mixture to blood biochemistry, hematology, and platelet coagulation, subacute toxicity study was conducted. Methods. AuNP and AgNP in which their size distribution was not statistically different, mixed or separate, were injected into the caudal vein of male Sprague-Dawley rats for 4 weeks. The rats were allowed to recover for a further 4 weeks in order to examine systemic toxicity expressed in the blood biochemistry and hematology. The dose groups (5 males per group for the administration and 3 males for the recovery) consisted of 7 divisions, i.e., control, AgNP (with a low dose of 10 μg/kg/day and a high dose of 100 μg/kg/day), AuNP (with a low dose of 10 μg/kg/day and a high dose of 100 μg/kg/day), and mixed AgNP/AuNP (with a low dose of 10/10 μg/kg/day and a high dose of 100/100 μg/kg/day). Results. There were no significant dose-related changes in the hematology and blood biochemical values for the rats. Coagulation time in terms of the active partial thromboplastin time (APTT) and prothrombin time (PT) did not show any significant changes, when compared to the control group. Conclusion. The subacute injection of AuNP and AgNP or their mixture did not induce any noticeable systemic toxicity.

An experiment was conducted to investigate the counteracting effects of spirulina in Long Evans rats exposed to oral potentiated sulfonamide administration. 20 rats were randomly assigned into four equal groups (A, B, C and D) and were fed with standard broiler pellet (25g/rat/day) throughout the experimental period of 60 days. Rats of Group A were fed only with pellet without any experimental diet and were defined as control. Rats  of Group B were treated with potentiated sulfonamide @ 96 mg/rat/day orally whereas Group C was treated with potentiated sulfonamide @ 96 mg/rat/day plus spirulina (Spirulina maxima) @ 50 mg/rat/day orally (low dose spirulina). In Group D, potentiated sulfonamide and spirulina (Spirulina maxima) were given through feed @ 96 mg/rat/day and @ 100 mg/rat/day (high dose spirulina) respectively. Hematological parameters (TEC, Hb and absolute count of lymphocyte, neutrophil and eosinophil) and hispathological profile of liver and kidney were recorded. The investigation revealed that the oral administration of sulfonamide significantly (p<0.01) decreased the TEC (5.93±0.24) value, number of lymphocyte (581.76±3.70) and neutrophil (581.76±3.70) compared to other treated groups and control group. On the other hand significant (p<0.01) increase (422.86±2.34) in eosinophil population has been found in rats fed on sulfonamide irrespective of spirulina supplementation on the final day of experiment compared to other treated group and control group. From this experiment it is evidenced that spirulina has a potential counteracting effect against sulfonamide. Histopathology of kidney and liver was done at the end of experiment (60 days) and no significant change was found except in the kidney of Group B and C.DOI: http://dx.doi.org/10.3329/bjvm.v10i1-2.15650

Background: The hematopoietic growth factor erythropoietin (EPO) attracts attention due to its all-tissue-protective pleiotropic properties. The purpose of this study is to investigate the effect of EPO in experimental burn wounds healing. Methods: Fifteen healthy Sprague-Dawley, strain of Rattus Novergicus weighing 300-350 grams, were prepared to achieve deep dermal burns. Animals were randomized to receive either low-dose EPO injection (600 IU/mL), high-dose EPO injection (3000 IU/mL) or nothing (control group). After 14 days of observations, quantitative and qualitative assessments of wound healing was determined. Results: The size of the wound area and re-epithelialization rate percentage was determined on Day-0, Day-5, Day-10, and Day-14. The average of raw surface areas measurement (p value: 0.012 in day-5; 0.009 in day-10 and 0.000 in day-14) and healing percentage of the lesions (p value: 0.011 in day-5; 0.016 in day-10 and 0.010 in day-14) were significantly best in the low-dose EPO grup compared to the control group and high-dose EPO grup. The histopathology evaluation revealed that the highest score for for re-epithelialization, granulation tissue and neo-angiogenesis were achieved by the low-dose EPO injection group than in both control and high-dose EPO injection groups. Conclusion: In this animal study using Sprague-Dawley rats, Recombinant Human EPO (rHuEPO) injection administration prompted the evidences of improved re-epithelialization and wound healing process of the skin caused by deep dermal burns. These findings may lead to a new therapeutic approach to improve the clinical outcomes for the management of burns wound healing.

Background The aim of this study was to compare the effect of antileukotriene (anti-LT), antihistamine, and a combination of anti-LT and antihistamine on the symptoms and nasal resistance in allergic rhinitis patients. Methods We performed a placebo-controlled study, with 120 persistent, moderate to severe allergic rhinitis patients randomly selected to receive the different treatments for 4 weeks: no treatment, 10 mg of cetirizine once per day, 20 mg of zafirlukast once per day, 20 mg of zafirlukast twice per day, a combination of 20 mg of zafirlukast and 10 mg of cetirizine once per day, or a combination of 20 mg of zafirlukast twice per day and 10 mg cetirizine once per day. The nasal secretion nitric oxide (NO) concentration, nasal symptom score, and nasal resistance were measured before and after treatment. Results Total symptom scores improved in each treated group compared with the control group (p < 0.05). Nasal obstruction significantly improved in the anti-LT-treated groups (p < 0.05). High-dose anti-LT or the combination of low-dose anti-LT and antihistamine significantly improved allergy symptoms compared with no treatment, low-dose anti-LT, or antihistamine alone (p < 0.05). Furthermore, anti-LT decreased NO concentration in nasal secretions (p < 0.05), regardless of the dose administered. Conclusion These results suggest that high-dose anti-LT alone or the combination of low-dose anti-LY and antihistamine can effectively treat allergic rhinitis.

Despite the various and newly developed chemotherapeutic agents in recent years, cisplatin is still used very frequently as a chemotherapeutic agent, even though cisplatin has toxic effects on many organs. The aim of our study is to show whether ghrelin reduces the liver toxicity of cisplatin in the rat model. Twenty-eight male Sprague Dawley albino mature rats were chosen to be utilized in the study. Group 1 rats (n = 7) were taken as the control group, and no medication was given to them. Group 2 rats (n = 7) received 5 mg/kg/day cisplatin and 1 ml/kg/day of 0.9% NaCl, Group 3 rats (n = 7) received 5 mg/kg/day cisplatin and 10 ng/kg/day ghrelin, Group 4 rats (n = 7) received 5 mg/kg/day cisplatin and 20 ng/kg/day ghrelin for 3 days. Glutathione, malondialdehyde (MDA), superoxide dismutase (SOD), plasma alanine aminotransferase (ALT) levels, and liver biopsy results were measured in rats. It was determined that, especially in the high-dose group, the MDA, plasma ALT, and SOD levels increased less in the ghrelin group as compared to the cisplatin group, and the glutathione level decreased slightly with a low dose of ghrelin, while it increased with a higher dose. In histopathological examination, it was determined that the toxic effect of cisplatin on the liver was reduced with a low dose of ghrelin, and its histopathological appearance was similar to normal liver tissue when given a high dose of ghrelin. These findings show that ghrelin, especially in high doses, can be used to reduce the toxic effect of cisplatin.

Objective. Berberine has been used to treat nonalcoholic steatohepatitis (NASH), which has been addressed in many studies. In this study, we investigated the molecular pharmacology mechanisms of berberine using metabolomic techniques.Methods. Sprague-Dawley rats were randomly divided into three groups (10 rats in each group): (i) normal control group; (ii) high-fat diet- (HFD-) induced NASH model group; and (iii) HFD berberine-treated group (i.d. 200 mg/kg). The handling procedure lasted eight weeks. Then, UPLC-Q-TOF/MS techniques coupled with histopathology and biochemical analyses were adopted to explore the mechanisms of berberine on the protective effects against NASH.Key Findings. (i) According to conventional test results, berberine treatment plays a fighting role in HFD-induced NASH due to its beneficial effects against insulin resistance, inflammation, and lipid metabolism. (ii) Based on UPLC-Q-TOF/MS techniques, metabolic profiles that involved sphingomyelin (SM), phosphatidylcholine (PC), lysophosphatidylcholine (LysoPC), 13-hydroperoxy-9, 11-octadecadienoic acid (13-HpODE), eicosatrienoic acid, docosatrienoic acid, and eicosenoic acid could provide potential metabolic biomarkers to address the pharmacological mechanisms of berberine.Conclusions. The parts of molecular pharmacological mechanisms of berberine for NASH treatment are related to the regulation of metabolic disruption involving phospholipid and unsaturated fatty acids in rats with NASH.
