Zusammenfassung:The informal aluminum industry is increasingly widespread in low- and middle-income countries, especially in Indonesia. Aluminum exposure is a serious public health problem, especially among workers in the informal aluminum foundry sector. Research on aluminum (Al) is important to advance our understanding of its impact on physiological systems. Here, we investigated the effect of exposure to aluminum longitudinal histological changes on the liver and kidneys of male mice. Mice were separated into six groups (4/group): group 1, group 2, group 3 received vehicles, and group 4, group 5, group 6 were administered a single dose of Al at 200 mg/kg b.w. by intraperitoneally every 3 days for 4 weeks. Post-sacrifice, kidneys and liver were isolated for examination. While Al did not impact the body weight gain of male mice across all groups, it caused liver damage including sinusoidal dilatation, enlarged central veins, vacuolar degeneration, and pyknotic nuclei in one-month-old mice. Furthermore, atrophied glomeruli, blood-filled spaces, and disintegration of renal tubular epithelium are evident at one-month-age. By contrast, sinusoidal dilatation and enlarged central veins were found in mice two- and three-months-old, including hemorrhage in mice (two-month-old) and atrophy of glomeruli. Lastly, the kidneys of three-month-old mice displayed interstitial fibrosis and increasing mesenchyme in the glomeruli. In summary, we demonstrated that Al provoked histological changes in the liver and kidneys with Al-treated 1-month mice being the most susceptible.
