Abstract
In this study, we investigated the effects of 3 different burn dressing treatments, including experimental, silver, and modern dressing materials, on systemic oxidative stress in rats with severe scald burns within the first 96 h. The rats were divided into five groups: a burn group (n = 10), a polylactic membrane group (n = 10), a silver sulfadiazine group (n = 10), a curcumin group (n = 10), and a control group (n = 10), consisting of equal numbers of female and male rats. In the first 4 groups, 30% of the rats' total body surface area was scalded at 95°C. The burn group was not treated. Each group was treated with group-name dressing material. The control group was neither treated nor burned. The rats were sacrificed, and blood and tissue samples were obtained at the 96th hour when severe effects of oxidative stress developed postburns. Systemic inflammatory biomarkers and oxidative stress parameters were examined. In addition, apoptosis and organ damage in liver, kidney, lung, and skin tissues were evaluated biochemically and histopathologically. When the parameters were statistically analyzed, we found that the systemic levels of oxidative stress and inflammatory damage to liver, kidney, and lung tissues were lower in the 3 treated groups than in the burn group. We believe that the dressing material's efficacy in the treatment of severe burns may be dependent on its ability to combat oxidative stress and inflammation.

An investigation of bovine papillomaviruses from ocular squamous cell carcinomas in cattle. IRANIAN JOURNAL OF VETERINARY RESEARCH 2023; 24:51-57. [PMID: 37378381 PMCID: PMC10291527 DOI: 10.22099/ijvr.2022.43152.6282] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/24/2022] [Revised: 12/06/2022] [Accepted: 12/11/2022] [Indexed: 06/29/2023]
Abstract
Background Ocular squamous cell carcinomas (OSCCs) in cattle has been studied for many years, but no definite etiology has been established. Squamous cell carcinomas (SCCs) may occur in different body parts of cattle. Depending on the location, it can cause an economic loss of varying degrees. Aims The aim of this study was to investigate the causes of OSCCs in the eye region of cattle. Methods: Sixty tumoral masses taken form 60 cattle with proliferation in the eye region that were collected between the years 2012-2022 were used. These cases were admitted to our department for routine diagnosis. The tissues were diagnosed as OSCC using histopathological methods. The presence of bovine papillomavirus (BPV), one of the causative factors, was investigated using immunohistochemical and polymerase chain reaction (PCR). Results Macroscopically masses were nodular or cauliflower-like and fragile and had hemorrhagic surfaces. Considering the keratin pearls, tumoral islands, and squamous differentiation, 20 out of 60 cases were classified as well, 20 as moderately, and 20 as poorly-differentiated OSCCs. 47 of the 60 cases were BPV positive using immunohistochemical methods. However, BPV nucleic acid was detected in only two cases with PCR. Only one of the cases could be sequenced. After phylogenetic analysis, virus strain was identified as BPV-1. Conclusion Our results indicated that papillomaviruses can contribute to the development of OSCCs, in both precursor lesions and also advanced stage OSCCs. We found that BPV-1 has a possible causative role; however, more studies are needed to investigate the role of other viral agents and their interaction with secondary factors.
