An intact animal group was included. Each group contained 6 individuals. Pathohistological examination of kidney tissue and\nbiochemical analysis of blood and kidney tissue homogenate were performed. Statistical analysis was done using the Mann-Whitney test.\nResults: Yellow granules were found in the glomerular tissue and tubular epithelium of rats. Volume voids were seen in the renal cortex with a medium-sized\nrenal artery. As nanoparticle doses increased, the number of functioning glomeruli decreased, and both atrophic and hypertrophic glomeruli with hyperplasia\nof capillaries appeared. Higher doses were associated with increased transamidinase activity, von Willebrand factor, creatinine, and urea levels in blood serum,\nalong with a decrease in ATP and total protein in kidney tissue. UV pre-irradiation of nanoparticles enhanced dystrophy, tissue death, and glomerular atrophy,\nwith more pronounced biochemical shifts.\nConclusions: Pathohistological and biochemical analysis showed that oral administration of GdYVO4:Eu3+ nanoparticles caused kidney damage, worsening\nwith increased doses. UV-activated nanoparticles exacerbated renal damage.<\/jats:p>","DOI":"10.36740\/wlek\/208990","type":"journal-article","created":{"date-parts":[[2025,8,25]],"date-time":"2025-08-25T09:59:06Z","timestamp":1756115946000},"page":"1302-1308","source":"Crossref","is-referenced-by-count":1,"title":["Experimental evidence of kidney damage following oral administration of gadolinium nanoparticles GdYVO4:Eu3+"],"prefix":"10.36740","author":[{"given":"Galina I.","family":"Galina -Vakulik","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Oksana A.","family":"Nakonechna","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Irina V.","family":"Sorokina","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tetiana V.","family":"Gorbach","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Svitlana A.","family":"Denisenko","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Svitlana I.","family":"Stepanova","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Natalia V.","family":"Yarmysh","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"22436","published-online":{"date-parts":[[2025,7,30]]},"container-title":["Wiadomo\u015bci Lekarskie"],"original-title":[],"link":[{"URL":"https:\/\/www.wiadomoscilekarskie.pl\/pdf-208990-128058","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.wiadomoscilekarskie.pl\/pdf-208990-128058","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,25]],"date-time":"2025-08-25T09:59:10Z","timestamp":1756115950000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.wiadomoscilekarskie.pl\/Experimental-evidence-of-kidney-damage-following-oral-administration-of-gadolinium,208990,0,2.html"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,7,30]]},"references-count":0,"journal-issue":{"issue":"7","published-print":{"date-parts":[[2025]]}},"alternative-id":["208990"],"URL":"https:\/\/doi.org\/10.36740\/wlek\/208990","relation":{},"ISSN":["0043-5147","2719-342X"],"issn-type":[{"value":"0043-5147","type":"print"},{"value":"2719-342X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,7,30]]}}}
