The aim of the present study was to evaluate selenium content in the gonads of healthy cats and those with impaired homeostasis with the use of fluorescence spectroscopy. Higher concentrations of selenium were found in the gonads of the male domestic cats studied. The average content of this element in the testes of healthy males was: 0.59 mg·kg while 0.47 mg·kg wet weight was recorded in the ovaries of females. In the case of individuals with impaired homeostasis, higher values of selenium were found in the ovaries of obese females (0.40 mg·kg), while in the case of females with diagnosed malignancy of the mammary gland, the average values were lower and amounted to 0.31 mg·kg wet weight of tissue. On the basis of statistical analysis, significant differences were found according to sex, age, and disturbed homeostasis of the individuals studied. An association was found between low Se in the gonads and obesity, as well as the presence of mammary gland neoplastic lesions. In addition, Se content was found to decrease with age in females, which can reduce resistance to oxidative stress.
本研究的目的是利用荧光光谱法评估健康猫以及体内稳态受损猫性腺中的硒含量。在所研究的雄性家猫的性腺中发现了较高浓度的硒。健康雄性猫睾丸中该元素的平均含量为：0.59毫克/千克，而雌性猫卵巢中记录的湿重为0.47毫克/千克。对于体内稳态受损的个体，肥胖雌性猫卵巢中的硒含量较高（0.40毫克/千克），而对于诊断为乳腺恶性肿瘤的雌性猫，平均值较低，组织湿重为0.31毫克/千克。基于统计分析，在所研究个体的性别、年龄和体内稳态紊乱方面发现了显著差异。在性腺中低硒与肥胖以及乳腺肿瘤性病变之间发现了关联。此外，发现雌性猫体内的硒含量会随着年龄的增长而降低，这会降低对氧化应激的抵抗力。
