عنوان المقالة:تأثير L-selectin وبعض المعايير الفسيولوجية للدم في العاملين في محطات غاز البترول المسال Effect of L-selectin and some blood physiological criteria in workers of LPG stations
This study was conducted on workers of liquefied
petroleum gas stations in the city of Najaf, Iraq, from December 2021
to January 2022. The workers (n=50) exposed to liquefied petroleum
gas (LPG) were compared with individuals who were not exposed (the
control group, n=38). The result showed a significant (P<0.05) and
clear increase in the level of L-Selectin of workers (0.4845 ± 0.1259
ng/ml) compared to the control group (0.9816 ± 0.01771 ng/ml ). The
current study, after conducting a statistical analysis of physiological
blood tests, showed a significant( P < 0.05) and clear decrease in the
number of red blood cells(RBC), blood platelets(PLT),
hemoglobin(HGB), and the percentage of hematocrit (MCT) , as it
reached 4.930 ± 0.07 x10^6 cell/ml , 198.2 ± 7.8 x10^3cell/ml , 15.05
± 0.17 g/dl , and 46.04 ± 0.41% respectively Compared to the control
group (5.213 ± 0.06 x10^6 cell/ml , 222.8 ± 9.1 x10^3cell/ml , 15.72
± 0.13 g/dl , and 49.14 ± 1.64% respectively ) . The study also showed
a significant increase ( P < 0.05) in the number of white blood
cells(WBC) and the percentage of lymphocytes(LYC %) among
workers who inhaled gas at gas filling stations, which reached 7.346 ±
0.21 x10^3 cell/ml and 36.35 ± 1.09 % , respectively, compared to
the control group (6.652 ± 0.15 x10^3 cell/ml and 32.20 ± 1.7 %
respectively ). The study concluded that the presence of inverse
relationships between lung capacity and L-selectin, as well as between
the latter and the studied physiological blood parameters, may be
indicative of one of them to the height of the other or vice versa, which
delays the occurrence of lung diseases and their complications for
these workers
