This study is to present a female high school summer blouse with high movement functionality and satisfying appearance. For the experimental research 6 subjects with closest average body shapes and their body surface was measured at beginning and after selecting a representative movement the tested uniform was worn and the appearance and movement functionality was evaluated. The results of this research are as follows. In the research with the aims to improve the sleeve designed the height in 3 types as A.H/4+3, A.H/4+2, A.H/4+1 and their evaluation showed that in the order of best appearance was A.H/4+2, A.H/4+1, A.H/4+3. In the order of best comfort was A.H/4+2, A.H/4+3, A.H/4+1 and the best order for movement functionality was A.H/4+1, A.H/4+2, A.H/4+3. Additional height types designed produced from elastic materials were A.H/4+3, A.H/4+2, A.H/4+1 and the resulting order of appearance was A.H/4+3, A.H/4+2, A.H/4+1, order of comfort was A.H/4+3, A.H/4+2, A.H/4+1 and the order of movement functionality was A.H/4+1, A.H/4+2, A.H/4+3. Integrating these results shows that in using the same concurrent materials, the experiment pattern of setting the sleeve height as A.H/4+2 was the best while in using elastic materials, the experiment pattern of setting the sleeve height as A.H/4+3 was the best.

가물치(Channa argus) 조직의 젖산탈수소효소 동위효소(EC 1.1.1.27, lactate dehydrogenase, LDH)를 정제하고 생화학적, 면역학적 및 역학적 방법으로 특성을 연구하였다. LDH 활성은 골격근이 380.4 units로 가장 높고 심장 13.4, 눈 3.5, 뇌 조직 5.4 units이었으며, 심장의 CS 활성은 20.7 unit로 가장 높고, LDH/CS는 골격근 172.9, 심장 0.6, 눈 0.32, 뇌 0.47이고, 단백질 양은 골격근 14.7 mg/g이며, 특이활성(units/mg)은 골격근 25.88, 심장 0.79, 눈 0.31, 뇌 1.38 units/mg이었으므로 골격근은 혐기적이고, 심장은 호기적이었다. LDH $A_4$, $B_4$, eye-specific $C_4$에 대한 항혈청을 사용한 Western blot, 면역침강반응 및 native-polyacrylamide gel electrophoresis에 의해 $A_4$, $A_3B$, $A_2B_2$, $AB_3$ 및 $B_4$가 모든 조직에서 확인되었고, 눈 조직에서 $C_4$와 $AC_3$, $A_2C_2$, $AC_3$, 뇌 조직에서 $A_3C$도 확인되었다. LDH $A_4$, $A_3B$, $A_2B_2$, $AB_3$, $B_4$, eye-specific $C_4$ 동위효소는 affinity chromatography와 Preparative PAGE Cell에 의해 정제되었다. LDH $A_4$ 동위효소는 $NAD^+$ 유입 후 정제되었고, eye-specific $C_4$는 $A_4$에 이어 용출되기 시작하였으며 $B_4$는 buffer 유입 후 용출되었다. 정제한 결과 $A_4$는 $B_4$ 및 eye-specific $C_4$와 분자구조의 일부가 유사하였지만 $B_4$와 $C_4$는 서로 다른 것으로 나타났으므로, 하부단위체 A는 보존적이고, 하부단위체 B는 A보다 더 빠르게 진화된 것으로 보인다. 피루브산 10 mM에서 $A_4$ 동위효소 39.98%, $A_2B_2$ 21.28%, $B_4$ 19.67% 및 eye-specific $C_4$ 16.87%의 활성이 남아있었고, 피루브산에 대한 $Km^{PYR}$은 $A_4$ 0.17 mM, $B_4$ 0.27 mM, eye-specific $C_4$ 0.133 mM였다. $A_4$, $B_4$, eye-specific $C_4$, $A_2B_2$, $A_3B$ 및 $AB_3$의 최적 pH는 각각 pH 6.50, pH 8.5, pH 5.5, pH 6.0-6.5, 5.0 및 pH 7.5였고, 동질사량체 $A_4$와 이질사량체 동위효소들은 넓은 pH 영역에서 안정하였다. 특히 골격근은 LDH 활성이 크므로 활동성이 크며, 눈조직에서 피루브산 친화력이 강한 eye-specific $C_4$에 의해 피루브산 대사가 빠르게 일어나고, 이어서 $A_4$에 의해 젖산이 산화되어지는 것으로 사료되므로, 종의 생태환경 및 먹이 획득 양식에 따라 LDH-C 발현, 기질에 대한 친화도 및 대사 시간이 다른 것으로 사료된다.

C4.4A, a metastasis-associated gene, encodes a glycolipid-anchored membrane protein which is overexpressed in several human malignancies. However, there are few data available on C4.4A expression and its relationship with progression in gastric cancer. Our study was designed to explore the expression of C4.4A in gastric cancer and to correlate it with clinical outcome. C4.4A expression was studied by quantitative real-time RT-PCR and immunohistochemistry for assessment of correlations with clinicopathological factors. C4.4A mRNA expression was significantly up-regulated in gastric cancer as compared with noncancerous tissue (p<0.05)., being observed in 107 (88.4%) of the 121 gastric cancer cases by immunohistochemistry. We found that the expression of C4.4A mRNA was correlated with size of the tumor, depth of invasion, lymph node metastasis, distant metastasis and TNM stage. Moreover, patients with overexpression of C4.4A has a significantly worse survival (p<0.05). Further multivariable analysis indicated that the expression of C4.4A was an independent prognostic indicator for gastric cancer (p<0.05). In conclusion, overexpression of C4.4A correlates with metastatic potential of gastric cancer and C4.4A could be a novel independent prognostic marker for predicting outcome.

풀망둑(Acanthogobius hasta) 조직의 젖산탈수소효소(EC 1.1.1.27 Lactate dehydrogenase, LDH) 동위 효소의 특성을 생화학적, 면역화학적 및 역학적 방법에 의해 연구하였다. 풀망둑 골격근과 눈 조직의 젖산탈수소효소 활성이 65.30과 53.25 units였고, 심장과 간 조직에서는 낮게 나타났다. 골격근 조직의 LDH/CS는 22.29로 가장 높고, LDH 특이활성도는 뇌 56.45, 눈 38.04 및 골격근 11.04 units/mg였다. 각 조직에 대해 $A_4,\;B_4$, eye-specific $C_4$, 및 liver-specific $C_4$에 대한 항혈청으로 면역 침강 반응시킨 후 Polyacrylamide gel 전기영동 하였다. 골격근, 뇌 및 눈 조직에서 $A_4$ 동위효소가 우세하게 확인되었고, 심장에서는 $A_4$ 동위효소가 확인되었다. 또한 양극의 eye-specific t와 음극의 liver-specific $C_4$가 한 종에서 함께 발현되었으며, 눈 조직의 eye-specific $C_4$는 활성이 크고 간 조직의 liver-Specific $C_4$의 활성은 낮게 나타났다. 결과 $A_4$와 $C_4,\;A_4$와 $B_4$ 및 eye-specific $C_4$와 liver-specific $C_4$의 분자구조의 일부가 서로 유사하지만 $B_4$와 $C_4$의 구조는 서로 다른 것으로 나타났으므로 하부단위체 A는 보존적이고 하부단위체 B는 하부단위체 A보다 빠르게 진화된 것으로 사료된다. 골격근 조직의 LDH $A_4$ 동위효소는 affinity chromatography에서 $NAD^+$를 함유한 buffer를 유입한 후 용출된 분획에서 정제되었고, eye-specific $C_4$ 동위효소는 $A_4$ 분획에 이어 용출되었으므로 eye-specific $C_4$가 $A_4$의 분자 구조와 유사한 것으로 보인다. 그리고 LDH에 대한 피루브산의 저해 실험 결과 35.22-43.47% 의 활성이 남았고, $Km_{pyr}$은 0.080-0.098 mM이고 골격근과 눈조직의 Vmax은 153.85와 35.09 units였다. 또한 $B_4$ 동위효소가 열에 대해 가장 안정하였고 $C_4$는 $A_4$보다 안정하였으며, 최적 pH는 6.5로 나타났다. 본 실험 결과 풀망둑은 저 산소 환경조건에 적응되어져 조직들의 동위효소들이 $A_4$와 $B_4$ 동위효소 사이의 특성을 나타냈고, 골격근과 눈 조직에서 피루브산에 대한 LDH의 친화력이 상당히 크므로 LDH가 혐기적 조건에서 효율적으로 기능을 하는 것으로 사료된다.

2-Aminothiazole ring as a bioisoster of catechol in dopamine has provided with good oral availability and lipophilic property. 2-Aminoindan, is a rigid form of dopamine, was evaluated as a dopamine D3 agonist with low neurotoxicity. Dopamine D3 agonist was evaluated as selective for the treatment of Parkinson's disease. In order to develop a novel dopamine D3 agonist, we tried to synthesize the aminothiazoloindenoxazine derivative that is a hybrid structure of aminoindenoxazine and thiazole ring. cis-2-Amino-1-indanol (2) was synthesized from 1,2-indandione-2-oxime by catalytic hydrogenation and it was treated with chloroacetyl chloride and NaH in benzene solution to give (${\pm}$)-cis-4,4a,5,9b-tetrahydroindeno[1,2-b][1,4]oxazin-3(2H)-one (6). Nitration of 6 by the mixed acid gave 8-nitro compound (7) and the carbonyl group of 7 was reduced with $LiAlH_4$ to afford compound (8). 8 was reduced to form (${\pm}$)-cis-8-amino-2,3,4,4a,5,9b-hexahydroindeno[1,2-b][1,4]oxazine (9) and finally it was cyclized with KSCN in glacial acetic acid to yield (${\pm}$)-cis-8-amino-2,3,4,4a,5,10b-hexahydrothiazolo[4,5-f]indeno[1,2-b][1,4]oxazine (10).

Structure-activity relationship studies of allylamine type of antimycotics were carried out to evaluate the effect of naphthyl and methyl portion of naftifine. Compounds with 4-fluorophenyl(2a-5a), 2-fluorophenyl(2b-5b), 2,4-dichlorophenyl(2c-5c), 2,6-dichlorophenyl(2d-5d), 4-nitrophenyl(2e-5e), and 2,3-dihydro-benzo[1,4]dioxan-6-yl( 2f-5f) instead of naphthyl group with hydrogen(3a-3f), methyl(4a-4f), and ethyl(5a-5f) in the place of methyl in naftifine were synthesized and tested their in vitro anti-fungal activity against five different fungi. Eight compounds(3a, 5a, 3c, 4c, 4d, 5d, 5e, and 4f) showed significant antifungal activity against T. mentagrophytes. (E)-N-Ethyl-(3-phenyl-2-propenyl)-4-nitro-benzenemethaneamine(5e) displayed moderate antifungal activity against all five different fungi.
