Diazepam may be a primary drug aimed at treating neurological diseases or an associated drug in the treatment of other diseases in the purpose of symptomatic therapy. The sedative effect of diazepam characterizes it as a drug that people usually use on their own and without a doctor’s supervision. Directly, but also through influencing the nervous system, diazepam disrupts proper functioning of all body organs. The purpose of this paper was to examine the effects of diazepam on blood and cytohistological parameters of rats in an in vivo experiment. Mallory-Azan and immunochistochemical staining methods BLX-CX and Survivin tissues of liver, kidney and spleen of rats were used to achieve the set goal. Cytometric analysis of rats detected cells in apoptosis and measurements of stereological parameters were made using a system according to Cavalier’s principle. Results of analysis of hematological and histological parameters indicate a detrimental effect of diazepam on blood parameters, as well as on structure and functioning of the liver, kidneys and spleen of rats. This paper is a foundation for further detailed scientific research with the aim of elucidating all harmful effects that diazepam has on all organs in the body of rats. This data could serve as a starting point for future studies in clinical pharmacology on therapeutic protocols for usage of diazepam-based sedatives.","PeriodicalId":55559,"journal":{"name":"Acta Veterinaria-Beograd","volume":"72 1","pages":"235 - 255"},"PeriodicalIF":0.6,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48617356","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Also, we examined the concentrations of malondialdehyde (MDA), protein levels of nuclear factor κB (NF-κB), and activity of catalase (CAT) in the left and right adrenal medulla. The investigated parameters were quantified by Western blot analysis, assay of enzymatic activity, and CAT Research ELISA kits. We found that CSI pro duced significantly increased levels of PNMT protein, and VMAT2 protein, as well as increased concentrations of A in the right adrenal medulla. However, we recorded that CSI increased protein levels of COMT and NF-κB, as well as the concentrations of MDA in the left adrenal medulla. Also, CSI decreased the activity of CAT only in the left adrenal medulla.

This study aimed to present the results of treatment of 30 dogs with injured cranial cruciate ligaments using a knee orthosis and describe the reasons for the conservative treatment of cranial cruciate ligament deficiency. The study was conducted between 2017 and 2019 and involved 30 dogs of various breeds aged 7 to 15, weighing from 2.5 kg to 45 kg, diagnosed with cranial cruciate ligament rupture. In the study, a stifle knee orthosis by the Polish manufacturer Admirał (Pl) was used in 29 dogs and, in one case, an orthosis by Balto (USA) was applied. In each case, the orthosis was selected individually, based on the measurements taken. In the twelfth week of treatment using orthoses, the owners of 25 dogs were satisfied with the results of conservative treatment with the application of orthoses. The caretakers of four dogs observed difficulties in the form of slight lameness at rest after prolonged exertion on the previous day. Running difficulty was observed in one dog. In the conducted study, the knee orthosis demonstrated good therapeutic effects in dogs up to 25 kg. In the majority of dogs, a slight increase in the flexion angle of the treated knee joints was observed, X-ray examinations did not show the degenerative disease progress during the studied period.","PeriodicalId":55559,"journal":{"name":"Acta Veterinaria-Beograd","volume":"72 1","pages":"111 - 117"},"PeriodicalIF":0.6,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43020449","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since antibiotic resistance has become a global threat to both animal and human health, it is becoming more urgent to continuously search for new therapeutical alternatives for the control and treatment of bovine mastitis. Hence, our research aimed to test the therapeutic use of two essential oils (EOs) based on their chemical composition, antibacterial and antioxidant potential. The present study was conducted by collecting milk samples from the cows diagnosed with clinical or subclinical mastitis with the aim of isolating and identifying bacterial strains. The antioxidant potential of essential oils of Menthae piperitae (MP) and Melissa officinalis (MO) was evaluated in several in vitro assays. In the MP EO, a total of 38 compounds were identified, with menthol as the dominant compound, whereas in MO EO 51 compounds were identified. Furthermore, the values of minimal inhibitory concentrations (MICs) and minimal bactericidal concentrations (MBCs) have been used to quantitatively measure the antibacterial activity of each essential oil. In accordance with which, MP EO samples exhibited a higher degree of antibacterial activity than MO EO. Thus, EOs have been shown to be promising alternatives to antibiotics because of their availability, biodegradability, and lower risk of side effects as compared with conventional, antimicrobial treatment. Nevertheless, further clinical studies are needed to test the potential role of EOs in treating mastitis in dairy cows.","PeriodicalId":55559,"journal":{"name":"Acta Veterinaria-Beograd","volume":"72 1","pages":"45 - 58"},"PeriodicalIF":0.6,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69088603","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sample analysis of soil/sand was examined using qualitative methods without concentration (native slide) and with concentration (passive sedimentation and gravitational centrifugal flotation). In total, 106 samples have been collected out of which 60 samples of soil, 36 of dog faeces and ten samples of sand. Seven different agents have been detected, out of which five nematodes - Ancylostoma/Uncinaria spp., Trichuris spp., Capillaria spp., Toxocara spp., Toxascaris leonina and two protozoa - Isospora spp. and Giardia intestinalis. The overall prevalence of contamination of soil samples was 31.67% and a statistically significant difference in the prevalence of ancylostoma eggs was found between different locations. The most common agent detected in the dog’s faeces was Isospora spp., with a prevalence of 5.56%, followed by Giardia intestinalis and ancylostomatids with a prevalence of 2.78% each. The sand samples had no parasitic elements found. The contamination by parasites and by dogs’ faeces was equally dispersed in all segments of the examined locations.

Our approach was to “recycle” the well-established larvicide, and by studying the tablets, pellets and granules as floating or sinking formulations, we found a method to optimise the use of diflubenzuron against Culex pipiens mosquitoes in field conditions. A standard WHO procedure was used to test the larvicide efficacy. The combined efficacy of all floating formulations was 10.7% higher than sinking preparations (p-value =0.002) and that maximised throughout the experiment on days 14 and 21, (p-values 0.012 and 0.008, respectively). All floating formulations kept their efficacies above 70% until day 21 of the experiment, while the mortality of sinking designs dropped significantly after day 14. The lowest efficacy was observed when sinking granules were used and the highest when floating tablets were applied in the canals. Only the floating tablets showed no significant changes in efficacy from day 1 to 21, but then that efficacy drops sharp until day 35. Since the larvae spend most of their time on the surface of the slow-moving waters to breathe, and floating pellets and tablets are made of materials that can serve as food sources, we conclude that these formulations have a higher efficacy, at least in conditions of non- or slow-moving waters. This study shows the importance of a systematic approach to reformulation of old, already proven and environmentally safe larvicides which can control the mosquito populations and their spreading of various pathogens.","PeriodicalId":55559,"journal":{"name":"Acta Veterinaria-Beograd","volume":"72 1","pages":"87 - 99"},"PeriodicalIF":0.6,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45997475","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of the present study was to evaluate the anthelmintic efficacy and productive performance in pasture-raised beef calves, treated with macrocyclic lactones. A Split plot in time randomized block design was used to assess weight gain and reduction in fecal egg count (FECs) of treatments: 1% moxidectin (1% MOX), ivermectin (IVM) and abamectin (ABM) (2.25% IVM+1.25% ABM), 4% IVM, 3.15% IVM and placebo.

To determine the possibility of improving milk hygiene quality, training of extension service professionals and farmers was conducted, corrective and preventive measures were determined and the achieved state was monitored on 128 dairy farms where SCC and TBC were observed at regular monthly intervals for 6 months. The results showed a continuous statistically very significant improvement in hygienic conditions in barns, milking procedures, udder hygiene before, during and after milking, milking machine hygiene, as well as milk cooling procedures.
