안영수,An, Yeong-Su 한국항공우주산업진흥협회 2003 航空宇宙 Vol.81 No.-
지난 5월 22일 산업자원부(미래전략산업분과위원회)가 주최하고 전자부품연구원이 ''''미래전략산업 발전전략 세미나''''에서는 21세기의 급변하는 세계 경제상황과 치열한 경쟁속에서 국가경쟁력 강화를 위한 차세대 성장동력을 발굴, 선정하여 미래 전략산업 분야의 발전비전이 제시되었다. 다음은 산업연구원 안영수 연구위원이 항공우주분야에 차세대 성장동력으로 선정된 다목적헬기, 차세대 전투기, 소형 여객기, 무인항공기, 인공위성의 5개 분야를 중심으로 발표한 항공우주산업 발전전략을 정리한다.

BSO 유도 글루타치온 저감 흰쥐에서 1,2,4-trichlorobenzene의 급성독성
안영수 한국독성학회 1996 Toxicological Research Vol.12 No.1
1,2,4-trichlorobenzene (1,2,4-TCB) is used as a dye carrier, an intermediate in the syn[hesis of herbicides, aflame retardant, and for other purpose. After a single oral administration of 1,2,4-TCB (200 mg/kg, 400 mg/kg) in rats, toxic effects were studied by means of serum biochemical and hematological analysis, and liver calcium concentration. Administration of 1,2,4-TCB resulted in dose-dependent manner liver and kidney damage being suggested by increased serum alanine aminbtransferase (ALT) activities, liver calcium concentration and blood urea nitrogen (BUN). Pretreatment with DL-buthionine sulfoximine (BSO, 2 mmol/kg, i.p.) considerably decreased liver glatathione concentration, which was accompanied by markedly elevated serum ALT activites. It is well-known that toxicity of halogenated benzene such as bromobenzene, 1,4-dichlorobenzene is increased by pretreatment of phenobarbital, and protected by pretreatment of cytochrorn P450 inhibitor including metyrapone. However, there were no obvious alterations in toxicity of 1,2,4-TCB by pretreatment of phenobarbital or metyrapone. In comparison with control group, treatment groups exhibited significant changes in some parameters of hematological analysis but all hematological values remained within normal ranges.

Phosphorylation of 44-kilodalton Proteins in Peripheral T-lymphocyte of Rat
안영수,주일로,오도연,임승욱,박경선,Ahn, Young-Soo,Jou, Il-O,Oh, Do-Yeun,Lim, Seung-Wook,Park, Kyung-Sun The Korean Society of Pharmacology 1991 대한약리학잡지 Vol.27 No.2
Using T-lymphocytes obtained from rat peripheral blood, we found that the 44kD/pI6.8 protein was the major phosphoprotein of T-lymphocytes under basal condition, and that the 44kD/pI6.3 protein was a new phosphoprotein appeared in T-lymphocytes stimulated with ${\beta}-agonist$. The phosphorylation of the 44kD/pI6.3 protein was also induced by forskolin but inhibited by H-8 pretreatment. To clarify the character of the 44kD/pI6.3 protein, we used Con-A and kinase inhibitors, H-7 and W-7. Con-A stimulation induced phosphorylation of 44kD/pI 6.3 protein but that was inhibited by W-7 pretreatment. The phosphorytation of 44kD/pI6.3 protein was not induced by the PKC activator, PMA. Instead, the phosphorylation of 44kD/pI6.8 protein was reduced by H-7, a PKC inhibitor. From the above results,it can be concluded that the 44kD/pI6.3 protein can be a common substrate for A-kinase and CaM kinase. The two dimensional tryptic peptide mapping revealed that the 44kD/pI6.8 and 44kD/pI6.3 proteins are different.
