The Effects of Total Parenteral Nutrition on Plasma Aluminium Level in Premature

There are studies showing that parenteral nutrition fluids used for adaptation of preterm infants contain aluminum. It is known that aluminum accumulates in the body, disrupts mental development, affects bone mineral structure. In our study, we aimed to investigate parenteral nutrition and aluminum transmission in preterm infants. A total of 45 babies born during pregnancy week ≤32 and / or under 1500 gr were included in the study. A statistically significant increase was observed when we compared the levels of aluminum in the cord blood and in the 14th day of the patients. When the factors affecting serum aluminum levels were examined, no significant difference was found between birth weight, birth week and gender. No statistically significant difference was found between the duration of taking antibiotics, inotropic drugs serum aluminum levels. Statistically significance was found between number of days of furosemid administeration and serum Al levels. Longer parenteral nutrition was associated with greater increase in serum aluminium levels. A significant positive correlation was found between serum aluminium levels on 14th day and the calcium and magnesium levels in the TPN solutions which were administered in the first 7 days. In conclusion, the increase in serum aluminum levels in preterm infants fed parenteral nutrition was found to be statistically significant. In infants with longer parenteral nutrition, the increase in serum aluminum levels was greater. It is planned to continue our research in terms of long term effects of aluminum.

Effects of occupational exposure to aluminium on some oxidative stress and DNA damage parameters

Aim: The aim of this work was to investigate the relationships between aluminium levels, oxidative status and DNA damage in workers occupationally exposed to aluminium. Subjects and methods: This study was conducted in a secondary aluminium smelter. It included 96 male workers occupationally exposed to aluminium fume and dust compared to 96 male nonexposed individuals. Full history and clinical examination were done for all participants. Laboratory investigations in the form of serum aluminium, total antioxidant capacity (TAC), urinary 8-hydroxy-2′-deoxyguanosine (8-OHdG) and comet assay test were performed. Results: Serum aluminium level ranged from 4 to 30 µg/L of median: 10 µg/L; urinary 8-OHdG ranged from 2.7 to 17.2 ng/mg creatinine of median: 7.6 ng/mg creatinine; comet tail length (CTL) ranged from 19.7 to 50.5 µm of median: 45 µm, were statistically significantly increased in the exposed group compared to nonexposed group. In exposed workers, a statistically significant positive correlations were found between serum aluminium level and urinary 8-OHdG ( r = 0.75, p < 0.001); aluminium level and CTL ( r = 0.71, p < 0.001); and urinary 8-OHdG and CTL ( r = 0.71, p < 0.001). There was a statistically significant negative correlation between serum aluminium and TAC ( r = −0.76, p < 0.001). Conclusion: Occupational exposure to aluminium in secondary aluminium smelters was related to the induction of oxidative stress and DNA damage. This may promote the development of adverse health hazards in the exposed workers

Selected Blood Serum Elements in Van (Turkey) Cats

The Turkish Van cat originates from eastern Turkey. One of the characteristic features of Van cats is the colour of their eyes, which can be both eyes blue, both eyes amber or one eye blue and the other amber. Serum essential trace, macro and industrial element concentrations of Van cats (n = 47) according to sex, age, hair length and eye colour differences were investigated. Serum aluminium, arsenic, boron, barium, cobalt, chromium, copper, gallium, indium, iron, lead, lithium, manganese, nickel, selenium, silver, sulphur, strontium, vanadium and zinc were measured with ICP-OES plasma optical atomic emission spectrometer. In result, serum aluminium, barium, copper, manganese and strontium levels in male cats were found higher (p < 0.05) than in female cats. Serum aluminium, copper, manganese, strontium and zinc amounts of blue-blue eyed cats were found higher (p < 0.05) than amber-amber, amber-blue and blue-amber eyed cats, and serum lithium of blue-amber eyed cats was higher (p < 0.05) than blue-blue eyed cats. There were no statistically significant differences (p &#x003E 0.05) found in the age and hair length groups. Our results indicate that several of the blood serum elements of Van cats may be related to their eye colours and sex differences.
