Control group consisted of 22 bitches which were clinically healthy and in luteal phase of the estrus cycle. On clinical examination, pyometra was diagnosed in 40 bitches while 23 out of 40 bitches had open-cervix pyometra and 17 of 40 bitches had closed-cervix pyometra. Evaluation of haematological changes revealed that there was increased white blood cell (WBC), total protein (TP), globulin, alkaline phosphatase (ALKP) while decreased glucose (Glu), albumin (Alb) and albumin globulin ratio in pyometra cases (p<0.001). The highest WBC and ALKP levels were detected in closed-cervix pyometra group (p<0.001). Calcium (Ca+2) levels had significant rise in open-cervix pyometra cases (p<0.05) while phosphorus (Phos) levels had tendency to increase in closed-cervix pyometra cases (p=0.08). Also, Ca was directly correlated with Glu, Alb and TP while inversely correlated with WBC and blood urea nitrogen/creatinine (BUN/Crea). However, Phos was significantly associated with BUN and Crea (p<0.001; R=0.915 and R=0.860, respectively). As a result of this study, it was observed that the increased Ca levels in open-cervix cases and the elevated Phos levels in closed-cervix cases, were associated with the biochemical parameters related to hepatic and renal dysfunction in dogs with pyometra.","PeriodicalId":94175,"journal":{"name":"Polish journal of veterinary sciences","volume":"27 2","pages":"241-247"},"PeriodicalIF":0.0,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142904710","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Disease progression leads to oxidative stress, resulting in the depletion of uterine antioxidants and lipid peroxidation of associated cells, which further aggravates the condition. The concentration of antioxidant enzymes, the level of lipid peroxidation within the uterine tissue, and its reflection in the serum and urine need to be elucidated. The aim of this study was to analyze the concentration of antioxidants such as superoxide dismutase (SOD), catalase (CAT), glutathione (GSH), glutathione peroxidase (GPx), and the lipid peroxidation marker malonaldehyde (MDA) in three types of samples, i.e., serum, urine, and uterine tissue. For this purpose, 58 pyometra-affected and 44 healthy bitches were included in the present study. All animals underwent ovariohysterectomy (OVH). Our data indicated highly significant difference (p<0.01) in the antioxidant concentrations of uterine, serum and urine samples. Furthermore, there was a highly significant (p<0.01) difference in the serum levels of ferric reducing antioxidant power (FRAP) and free radical scavenging activity (FRSA) indicated poor capacity to overcome oxidative stress in the CEH-Pyometra condition. We showed that CEH-P induces oxidative stress, which further depletes the antioxidant enzyme reserves in the uterus. Thus, the weak antioxidant defence predisposes to uterine damage and disease progression. The simultaneous depletion of antioxidants and an increase in lipid peroxidation in the serum and urine may also act as early indicators of uterine pathology.","PeriodicalId":94175,"journal":{"name":"Polish journal of veterinary sciences","volume":"27 1","pages":"43-52"},"PeriodicalIF":0.0,"publicationDate":"2024-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140178393","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, the effect of dressings administered with different antiseptic agents on testicular functions in rats that underwent abdominal incisions was investigated. A total of 48 Sprague-Dawley rats were used in the study. Each of the rats in the study group underwent a 4 cm-long skin and muscle operation. The incision was then stitched immediately. Antiseptics, hemp seed oil, hemp leaf oil, and cannabidiol oil were then administered to the rats for 10 days to provide antisepsis.

Levels of SOD, CAT activities, and GSH content were found to be lower in the antiseptic group than in the hemp seed oil, hemp leaf oil, and cannabidiol oil groups (p<0.05). In testicular histology, the SEED group had the highest Johnsen score, and the antiseptic group had the lowest score (p<0.05). While JAK, P-JAK2, STAT3, PSTAT3, and NF-κB were generally higher in the antiseptic group compared to the other groups, they were lower in the SEED group.

In this study, the protective effect of chitosan on arsenic-induced nephrotoxicity and oxidative damage was investigated. 32 male Wistar-albino rats were divided into 4 groups of 8 rats each as control group (C), chitosan group (CS group), arsenic group (AS group), and arsenic+chitosan group (AS+CS group). The C group was given distilled water by oral gavage, the AS group was given 100 ppm/day Na-arsenite ad libitum with drinking water, the CS group was given 200 mg/kg/day chitosan dissolved in saline by oral gavage, the AS+CS group was given 100 ppm/day Na-arsenite ad libitum with drinking water and 200 mg/kg/day chitosan dissolved in saline by oral gavage for 30 days. At the end of the 30-day experimental period, 90 mg/kg ketamine was administered intraperitoneally to all rats, and blood samples and kidney tissues were collected. Urea, uric acid, creatinine, P, Mg, K, Ca, Na, Cystatin C (CYS-C), Neutrophil Gelatinase Associated Lipocalin (NGAL) and Kidney Injury Molecule 1 (KIM-1) levels were measured in serum samples.
