칼럼 - 미세먼지 해결을 위한 선(先) 이해와 후(後) 시행
김순태,Kim, Sun-Tae 대한석유협회 2018 석유와 에너지 Vol.2018 No.-
국내에서 대기 중에 존재하는 미세먼지 ($PM_{10}$, $PM_{2.5}$) 농도는 법적 허용치인 대기환경기준을 현재 초과하고 있으며, 2018년 3월말 강화된 기준을 달성하기 위해서는 어쩌면 우리가 '상상'할 수 있는 모든 방안을 이끌어내고 적극적으로 시행하는 방법 외에는 다른 선택의 여지가 없을 지도 모른다. 참으로 어려운 문제이다. 환경부의 2017년 대기환경연보를 보면 2016년 서울의 $PM_{2.5}$ 농도는 $26{\mu}g/m^3$으로 새로운 기준인 $15{\mu}g/m^3$를 달성하기 위해서는 대략 $11{\mu}g/m^3$ 만큼의 미세먼지 농도 감소가 필요하다. 중국 등 국외 배출량의 영향이 감소하고는 있다지만, 아직은 그 영향이 작지 않다. 많은 국민들이 이미 인지하고 있듯이, 국외 영향이 절반을 차지한다고 가정하면, 우리는 우리가 배출하는 모든 것을 중지시켜야 목표 농도 달성이 가능할 정도다. 과연 그 누가 그러자고 선 듯 나서서 말할 수 있을까?

The present study was investigated fatty acid composition of the phospholipid in the RBC membrane, liver and microsomal fraction after vitamin E and/or insulin treatment to evaluate the effect of vitamin E on the oxidative stress in STZ-treated rat and BB rat. Results obtained through the experiments were summarized as follows; 1. Effect of vitamin E and/or insulin treatment in STZ-treated rat 1) In the insulin treated group and the combination treated groups of vitamin E with insulin, body weights were increased compared to STZ-treated rat(STZ control group). Especially it was more significantly increased in the combination treated group of high dose vitamin E with insulin. 2) The composition of fatty acids of the phospholipid in RBC membrane, liver and microsomal fractions was shown a decreased C16:1, C18:1, C20:4 and an increased C16:0, C18:0, C18:2 in STZ control group compared to normal control group. In RBC membrane, liver and microsomal fractions after vitamin E with insulin treatment in STZ-treated rat, effect on the composition of fatty acids of the phospholipid was shown the result of a decreased C16:0, C18:0, C18:2 and an increased C16:1, C18:1, C20:4. 3) Hemolysis rate of the RBC to $H_2O_2$ was increased in the STZ control group and it was decreased below the hemolysis level of normal control group by vitamin E treatment. 2. Effect of vitamin E and/or insulin treatment in BB rat 4) Only in microsomal fraction, fatty acid composition was different between insulin treatment group and vitamin E with insulin treatment group. It was increased C16:0 and C18:1, and decreased C18:0 and C18:2 in vitamin E with insulin treatment group: But C20:4 was not different in two groups. These results suggest that the combination treatment of vitamin E and insulin could prevent the oxidative change of fatty acids in P-lipid of the RBC membrane, liver and microsomal fraction in STZ-treated rats and BB rats.
BB 랫드 및 streptozotocin이 투여된 랫드에서 vitamin E와 insulin 병합 투여 영향 I. 지질과 단백질의 산화성 손상 및 혈청내 효소 활성도에 미치는 영향

The present study, to evaluate the effect of vitamin E on the oxidative stress in STZ-treated rat and BB rat, was investigated the biochemical enzyme activity in the serum, and malondialdehyde and carbonyl group in the RBC membrane, liver and microsomal fraction after vitamin E and/ or insulin treatment. Results obtained through the experiments were summarized as follows; 1. Effect of vitamin E and/or insulin treatment in STZ-treated rat 1) Lipid peroxidation level in RBC membrane, liver and microsomal fraction was significantly decreased in vi. tamin E and/or insulin treatment group, and especially more significantly decreased in vitamin E with insulin treated group. 2) Protein oxidation level in RBC membrane, liver and microsomal fraction was significantly decreased in vitamin E and/or insulin treatment group. And it was especially more significantly decreased in RBC membrane and liver of vitamin E with insulin treated group. 3) In the enzyme activity in the serum, the activity of AST and ALT was not altered in all experimental group. The increased ALP activity in STZ-treated group was significantly decreased in insulin treated group and vitamin E with insulin treated group. 4) Decreased level of albumin and creatinine after STZ treatment was significantly increased in vitamin E and/or insulin treated group. 5) Level of glucose, cholesterol and triacylglycerol in serum: Glucose level was not significantly different in vitamin E treated group compared to STZ control group. But it was significantly different in the insulin treated group and vitamin E with insulin treated group compared to STZ control group. The cholesterol content in the serum was significantly increased in STZ control group compared to normal control group. And except low dose vitamin E treatment group, it was significantly decreased in vitamin E and/or insulin treated group compared to STZ control group. The triacylglycerol content in the serum was significantly decreased in STZ control group and increased in high dose vitamin E treated group and vitamin E with insulin treated group. But it was not significantly different in low dose vitamin E treated group and insulin treated group compared to STZ control group. 2. Effect of vitamin E and/or insulin treatment in BB rat 1) Lipid peroxidation level in liver was decreased by vitamin E with insulin treatment compared to insulin treatment. But it was not different in microsomal fractions. 2) Protein oxidation level in liver and microsomal fraction was decreased by vitamin E with insulin treatment compared to insulin treatment only in microsomal fractions. These results suggest that the combination treatment of vitamin E and insulin could prevent the oxidative change of lipid and protein of the RBC membrane, liver and microsomal fraction in STZ-treated rats and BB rats.
Propionylthiocholine-Dithiobis 방법에 의한 사람과 몇몇 동물 혈청내의 Cholinesterase 활성도 측정

Determination of cholinesterase activity is a routine practice in many laboratories to detect the influence of cholinesterase inhibiting drugs such as organophosphate and carbamate insecticides. Among many different methods to determine the cholinesterase activity, the present method was the most recent, simple and accurate one for routine test in clinics. The results obtained in sera of human and the different species of animals by means of the present method were as follows: $5.76{\pm}1.12U/ml$ in human, $3.37{\pm}0.83U/ml$ in german shepherd, $0.61{\pm}0.18U/ml$ in rat, $14.91{\pm}3.10U/ml$ in mouse, $1.55{\pm}0.51U/ml$ in chicken, $0.28{\pm}0.11U/ml$ in slaughtered cattle and $0.50{\pm}0.10U/ml$ in slaughtered pig.
