Effect of x-rays on the electrolyte concentration of bovine aqueous and vitreous humour

O.B. Ajayi, G.N. Atuanya

Abstract


The eye interacts constantly with a wide range of physically occurring materials like x-rays, air pollutants and toxins. The purpose of this study was to investigate the effects of X-rays on the electrolyte concentration of bovine aqueous and vitreous humour. Aqueous and vitreous humours were obtained from the eyes of certified healthy cows freshly slaughtered in the government abattoir at Ikpoba Slope, Benin City, Edo State, Nigeria. These cows’ eyes were enucleated within 2 hours after the death of the animals, and the right eyes were separated from the left eyes. The aqueous humour (AH) and vitreous humour (VH) samples were collected using a 12ml syringe and a needle through scleral puncture made on the lateral canthus and the total extractable aqueous or vitreous humour aspirated from each eye separately. The eyes were transferred to the University of Benin Teaching Hospital (UBTH) Radiology Department where they were irradiated with X-rays machine (VARIAN Medical System model 93061 -7t). Before irradiation, the eyes were removed from ice and allowed to thaw for about 3 minutes. Determination of electrolyte concentration were determined using E110111 flame Photometer (Antex Diagnostics, Beijing, China). Results show that radiation had no statistically significant effect on the mean concentrations of cations and anions in both AH and VH in this study (p > {0.05}). It is therefore concluded that radiation had no statistically significant effect on the mean concentrations of potassium ion and chloride ion in both AH and VH.
