The objective of the current study was to determine the impact of three different anaesthetic protocols on blood and biochemical parameters. Eighteen female Wistar rats (HsdOla:WI) 3 months old, weighting 197.09 ± 7.39 g were used. Baseline blood collection was performed in all animals from the lateral coccygeal vein for evaluation of glucose. The animals were then randomly allocated to receive one of three different anaesthetic protocols: dexmedetomidine/ketamine intramuscularly (0.25 mg/kg and 50 mg/kg respectively), or isoflurane 0.2 ml on cotton inside a syringe case, or isoflurane administered by vaporiser (5% induction and 2-3% maintenance of anaesthesia, delivered in oxygen flow 1 L/min). Blood samples were collected from caudal vena cava for complete blood count and biochemical analysis, while the lung and the liver were harvested for histological evaluation. Comparison between groups, as far as complete blood count parameters is concerned, revealed statistical significant differences in red blood cells, haematocrit and haemoglobin values with lower values being observed in vaporiser anaesthesia group. Furthermore, within group comparison revealed statistical significant differences for glucose in all three groups. No evidence of inflammatory, degenerative neoplastic or toxicity related lesions were observed during histological evaluation of the lung and liver.

Objectives The objective of this study was to verify the safety of policosanol supplementation for domestic cats. The effects of raw and encapsulated policosanol were compared with positive (L-carnitine) and negative (no supplementation) controls on outcomes of complete blood count, serum biochemistry, energy expenditure, respiratory quotient and physical activity in healthy young adult cats. Methods The study was a replicated 4 × 4 complete Latin square design. Eight cats (four castrated males, four spayed females; mean age 3.0 ± 1.0 years; mean weight 4.36 ± 1.08 kg; mean body condition score 5.4 ± 1.4) were blocked by sex and body weight then randomized to treatment groups: raw policosanol (10 mg/kg body weight), encapsulated policosanol (50 mg/kg body weight), L-carnitine (200 mg/kg body weight) or no supplementation. Treatments were supplemented to a basal diet for 28 days with a 1-week washout between periods. Food was distributed equally between two offerings to ensure complete supplement consumption (first offering) and measure consumption time (second offering). Blood collection (lipid profile, complete blood count, serum biochemistry) and indirect calorimetry (energy expenditure, respiratory quotient) were conducted at days 0, 14 and 28 of each period. Activity monitors were worn 7 days prior to indirect calorimetry and blood collection. Data were analyzed using a repeated measures mixed model (SAS, v.9.4). Results Food intake and body weight were similar among treatments. There was no effect of treatment on lipid profile, serum biochemistry, activity, energy expenditure or respiratory quotient ( P >0.05); however, time to consume a second meal was greatest in cats fed raw policosanol ( P <0.05). Conclusions and relevance These data suggest that policosanol is safe for feline consumption. Further studies with cats demonstrating cardiometabolic risk factors are warranted to confirm whether policosanol therapy is an efficacious treatment for hyperlipidemia and obesity.

The Impact

Objectives: Oxidative stress (OS)-related pathologic conditions in the tissues of living organism have been linked to exposure to stressful events within the environment. This study examined the impact of different kinds of stress exposure on glutathione (GSH)-related antioxidants. The effect of stress was examined using comparative levels of GSH, glutathione-S-transferase (GST) and glutathione peroxidase (GPx) in female Wistar rats. Materials and Methods: One hundred and sixty-eight adult female Wistar rats with body weights ranging between 150 and 200 g, were used for the study. The animals were distributed into 28 groups of six animals each. The experimental animals were routinely exposed to three different stressors; restraint chamber test, mirror chamber test and intruder chamber test for a duration of 1, 3 or 5 h per day for 1, 2 and 3 weeks, respectively. All animals were allowed free access to food (rat chaws), with water ad libitum. Animals were euthanise through cervical dislocation after the experimental period and the different target tissues were carefully harvested and homogenised for antioxidant estimation following standard procedure. Data obtained were statistically analysed and values expressed as mean ± standard error of mean and P < 0.05 level was considered as statistically significant. Results: Findings from this study elucidated the fact that exposure to stress is capable of causing marked OS and reducing GSH-based antioxidant activities in Wistar rats. A decline in the GSH level and GPx activity as observed in the study is an indication of alterations of kidney and brain tissue cellular integrity by free radicals generated during exposure to the stressors, while the observed significant increase in GST activity level in the affected tissues indicates compromised rapid exhaustion of the cellular system. Conclusion: Hence, we conclude that stress of different nature, intensity and duration can alter the levels of GSH-related antioxidants, especially in the kidney, ovary and brain tissues of stressed Wistar rats. The GSH levels in liver tissues were observed not to have changed significantly despite the oxidative damage caused by the stressors.

The aim of the study was to evaluate the main and interactive effects of chromium(III) propionate complex (Cr3) supplementation and different iron supply on the carbohydrate metabolism, lipid profile and other selected biochemical parameters of rats. The experiment was carried out in a two-factor design, in which rats were fed a diet with different proportions of Fe(III) and Cr(III) for six weeks. Fifty-four healthy female Wistar rats were divided into nine experimental groups with different Fe(III) levels, i.e. adequate—control group (45 mg/kg)—100% recommended daily dietary dose of Fe for rodents, deficient (5 mg/kg) and oversupply (180 mg/kg—400%). At the same time they were supplemented with Cr(III) of doses 1 (adequate), 50 and 500 mg/kg of diet. The activity and concentrations of most biochemical parameters were measured with standard enzymatic, kinetic, and colorimetric methods. HOMA-IR and QUICKI indexes were calculated according to appropriate formulas. It was found that there was an interactive effect of high Cr(III) doses and different Fe(III) levels in the diet on the carbohydrate metabolism and insulin resistance indexes. The presented results suggested that iron deficient diet fed animals led to insulin resistance; however, an effect is attenuated by Cr(III) supplementation at high doses. There were no significant changes in the rats’ lipid profile (except for the high density lipoprotein cholesterol (HDL-C) level) and most of the other biochemical parameters, such as the leptin, aspartate aminotransferase (AST), alanine transaminase (ALT), total protein (TP), creatinine (Crea) and the urea (BUN) concentrations. The study proved that the Cr(III) supplementation, independently and in combination with diversified Fe(III) content in the diet, affected the carbohydrate metabolism and insulin resistance indexes but did not affect lipid profile and most of the other biochemical parameters in healthy rats. The findings proved the role of Fe and Cr(III) and their interactions on disturbances carbohydrates metabolism.

Sodium nitrate (NaNO2) widely used as food additive for coloring and preserving meat has been reported to induce oxidative stress and cause histopathologic changes, nitrosative tissue damage, and lipid peroxidation in liver and kidney. Therefore, the present study compared the curative effect of chlorophyll fromSauropus androgynus(L) Merr and Cu-chlorophyllin as antioxidant in NaNO2-induced female Wistar rats based on haematological, serum biochemical, and histological evaluation. Thirty male Wistar rats were randomly assigned into six groups of five rats each. NaNO2were given at a subacute dose of 50 mg/kg bw intraperitoneally for 10 days. Chlorophyll fromS. androgynusand Cu-chlorophyllin from K-Liquid™ were given in the following 14 days at the two doses: 0,016 mg/mL and 0.008 mg/mL. NaNO2exposure resulted in significant reductions (p<0.05) in values of packed cell volume (PCV), haemoglobin (Hb) concentration and red blood cell (RBC) count, transferrin, and ferritin and elevation in malondialdehyde (MDA) level and schistocytes percentage with insignificant reductions in serum albumin and transferrin levels. Histology of kidney and liver were changed insignificantly (p>0.05) to normal values. Chlorophyll fromS. androgynusand Cu-chlorophyllin possess antioxidant potentials to protect against toxicities induced by sodium nitrate.

Intraperitoneal Chemoperfusion

Hyperthermic intraperitoneal chemoperfusion (HIPEC) is an established form of locoregional chemotherapy of peritoneum tumors. However, its efficacy and safety status remain a controversy, partially, due to scarce data on pharmacokinetics and toxicity profile of drugs under HIPEC. In the current study, 24 female Wistar rats were randomly assigned to receive cisplatin as HIPEC (n = 12, 20 mg/kg) or intravenously (i.v., n = 9, 4 mg/kg). The subgroups of three animals were used for the initial, intermediate, and late phases of the pharmacokinetic assessment. The animals were sacrificed on days 1 and 5. Blood, liver, kidney, and ovaries were evaluated for platinum content. Histological and immunohistochemical evaluation was undertaken in the liver and kidney. A trend for higher blood plasma platinum levels was observed for HIPEC compared to i.v. Significantly lower (p < 0.001) relative platinum binding to the proteins was observed in HIPEC animals compared to the i.v. administration. A five-fold higher concentration of cisplatin in HIPEC resulted in a ca. 2.5-fold increase in total blood platinum and ca. two-fold increase in blood ultrafitrable platinum (“free” Pt). Immunohistochemistry revealed higher kidney and liver damage after i.v. administration of cisplatin compared to HIPEC, although a five-fold higher dose of cisplatin was applied in HIPEC. Together with relatively lower absorption to the systemic circulation in HIPEC, higher protein binding is probably the primary reason for lower observed toxicity in HIPEC animals.

Thoroughbred Racehorses

Training has a strong effect on the physiology of hematological parameters and blood coagulation, both in humans and in horses. Several blood changes have been reported after exercise in horses but available data differ. We aimed to investigate modifications in complete blood count and some hemostatic parameters induced by the first training period in young untrained Thoroughbred racehorses to detect a possible labile blood coagulability in racehorses. Twenty-nine untrained 2-year-old Thoroughbreds were followed during their incremental 4-month sprint exercise schedule. Blood collection was performed once a month, five times (T-30, T0, T30, T60 and T90), before and during the training period for measurement of complete blood count (CBC) and blood clotting parameters (prothrombin time—PT, activated partial prothrombin time—APTT, thrombin clotting time—TCT, fibrinogen—Fb, thrombin–antithrombin complex—TAT). Differences among the time points for each parameter were analyzed (ANOVA, Kruskal–Wallis one-way analysis of variance, p < 0.05). In Thoroughbreds, the first long-term exercise workout period was found to induce a statistical increase in red blood cell indexes and lymphocytes, eosinophils and platelet counts, as well as a hypercoagulability state evident at 30 days of training, which returned to basal levels after 90 days. Regular physical exercise seems to blunt the negative effects of acute efforts on hematological and clotting parameters, an effect that may be attributed to the training condition.

Background: Cd and CPF intoxication may occur directly through drinking water. Since the population tend to receive combination of multiple intoxicants through environment contamination, there is need for conducting studies to assess the impact of individual and combined environmental pollutants. The present research work was designed to study hepatotoxicity induced by Cd, CPF and their combination.Methods: The experiment was carried out for 28 days in Wistar rats. G1: Control. G-2:CdCl2 @ 22.5mg/ kg b.wt / oral. G3: CPF @ 25 mg/ kg b.wt /per oral. G4:[email protected] mg + CPF @ 25 mg/ kg b.wt /per oral. Biochemical parameters ware estimated from serum and liver samples were processed for tissue antioxidative parameters and histopathological examination. Result: Higher mean values of AST, ALT, ALP and lower liver GSH and SOD were observed in G2, 3 and 4 on 15th and 29th day when compared with G1. Liver in G2 and 3 showed mild degenerative changes, areas of necrosis and loss of architecture. In G4, lesions were moderate in severity. In addition, moderate perivascular fibrosis of portal triad was observed. The effects in combined group were severe than individual groups due to synergistic action of the combined pollutants.

The present study’s objective was to evaluate the impact of Bunium incrassatum roots’ powder (Talghouda) as a dietary supplement on the evolution of biological, biochemical, and histological parameters in female Wistar rats. The animals were divided into two groups and given an orally standard diet supplemented with 15% of Bunium incrassatum roots powder, daily for 15 days. The obtained results showed that the roots of Bunium incrassatum induced an increase in the body and organs weight of Diet rats compared to the control, as well as effects on the biochemical parameters, characterized mainly by a significant increase in the glycaemia (+44.44%), triglyceride (+56.81%), cholesterol (+11.90%), LDL (+4.08%) and HDL (+11.53%)and a decrease in creatinine (-3.65%), TGO (-6.92%) and TGP (-58.73%). In the histological study of organs, the thyroid of diet rats revealed large thyroid follicles, the colloid of the follicles was more or less developed compared to the control rats. Through the obtained results, it can be concluded that a standard diet supplemented with 15% of Bunium incrassatum roots powder may have a positive effect on biological, biochemical, and histological parameters
