Abstract

Decrease in pulmonary function parameters (mostly in obstructive pattern) was shown to occur in workers exposed to high concentrations of sulfur dioxide ($SO_2$) during the process of apricot sulfurization. Since the mechanism by which inhaled $SO_2$ induce bronchoconstriction is still unclear, the effects of $SO_2$ exposure on serum TNF-$\alpha$, IL-1b, IL-6, IL-8, nitrite and nitrate levels are investigated in order to help the understanding of the mechanism of $SO_2$-induced bronchoconstriction. Serum samples were obtained from 40 volunteer workers after an hour of exposure to SO2 (mean level: 322.32 ± 219.65 ppm), and from 23 healthy controls without a history of exposure to this irritant gas. The measured serum levels of TNF-$\alpha$, IL-1b, IL-6, IL-8, direct nitrite, total nitrite and nitrate levels were found to be significantly (p<0.0001) increased in the workers' group compared to the controls. The mean serum levels of TNF-$\alpha$, IL-1b, IL-6, IL-8, direct nitrite, total nitrite and nitrate were 430.60 ± 397.03 pg/ml, 436.67 ± 316.31 pg/ml, 752.11 ± 394.95 pg/ml, 262.12 ± 287.99 pg/ml, 7.75 ± 3.34 mmol/L, 115.72 ± 48.78 mmol/L and 107.97 ± 46.19 mmol/L in the workers; while they were 9.83 ± 3.12 pg/ml, <5 pg/ml, 7.49 ± 1.27 pg/ml, 9.38±1.99 pg/ml, 2.17 ± 0.77 mmol/L, 59.91 ± 7.56 mmol/L and 57.74 ± 7.20 mmol/L in the controls, respectively. These results show that an increase in serum TNF-$\alpha$, IL-1b, IL-6, IL-8 and nitric oxide levels may be effective in the generation of $SO_2$-induced bronchoconstriction.

Özet

Kayısı kükürtleme işlemi sırasında yüksek konsantrasyonda sülfür diokside ($SO_2$) maruz kalan işçilerde pulmoner fonksiyonlarda düşüş (obstrüktif patern) olduğu önceki çalışmalarımızda gösterilmişti. $SO_2$'e bağlı bronkokonstriksiyonun mekanizması henüz belli olmadığından, bu mekanizmanın anlaşılmasına yardımcı olabileceği düşüncesiyle, $SO_2$ maruziyetinin serum TNF-$\alpha$, IL-1b, IL-6, IL-8, nitrit ve nitrat düzeylerine etkisi araştırıldı. Yaklaşık bir saat boyunca $SO_2$'e (ortalama düzey: 322.32±219.65 ppm) maruz kalan 40 gönüllü işçiden ve bu irritan gaza maruziyeti olmadığı bilinen 23 sağlıklı gönüllüden serum örnekleri alındı. Ölçülen serum TNF-$\alpha$, IL-1b, IL-6, IL-8, direkt nitrit, total nitrit ve nitrat düzeyleri işçilerde kontrol grubuna göre anlamlı düzeyde (p<0.0001) yüksek bulundu. TNF-$\alpha$, IL-1b, IL-6, IL-8, direkt nitrit, total nitrit ve nitrat için ölçülen serum düzeyleri işçilerde sırasıyla 430.60±397.03 pg/ml, 436.67±316.31 pg/ml, 752.11±394.95 pg/ml, 262.12±287.99 pg/ml, 7.75±3.34 mmol/l, 115.72±48.78 mmol/l ve 107.97±46.19 mmol/l olarak bulunurken; kontrol grubunda 9.83±3.12 pg/ml, <5 pg/ml, 7.49±1.27 pg/ml, 9.38±1.99 pg/ml, 2.17±0.77 mmol/l, 59.91±7.56 mmol/l ve 57.74±7.20 mmol/l idi. Bu sonuçlar, $SO_2$'ye bağlı bronkokonstriksiyonda serum TNF-$\alpha$, IL-1b, IL-6, IL-8 ve nitrik oksit düzeylerindeki artışın etkili olabileceğini düşündürdü.
