생리활성을 지닌 신경펩타이드의 구조와 활성간의 관계를 규명하기 위하여 고상법으로 합성한 세종류의 neuropeptide γ(mammalian-,trout- 그리고 goldfish-neuropeptide γ)를 사용하여 연구하였다. Circular dichroism spectra에 의하면 mammalian-,trout- 와 goldfish-neuropeptide γ는 완충액 조건하에 모두 random한 구조를 나타내었다. 중성 및 산성 지질 존재 하에서, mammalian-과 trout- neuropeptide γ는 여전히 random한 구조를 취하였다. 그러나, goldfish-neuropeptide γ는 중성 및 산성지질하에서 부분적으로 α-helix구조를 나타내었다. 장관 수축활성에 있어서는 carp 장관, guinea-pig 회장 그리고 rat십이지장에 대하여 비교하였다. Carp에 대해서는 goldfish-neuropeptide γ= trout- neuropeptide γ>mammalian-neuropeptide γ순으로 활서이 나타났다. 그러나, guinea-pig 회장과 rat십이지장에 대해서 mammalian-neuropeptide γ는 어류 유래성 neuropeptide g들 보다 높은 수축활성을 나타내었다. 이러한 결과들은 neuropeptide γ들이 종-특이적인 활성을 나타낸다는 것을 제시한다. The relationship between structure and biological activity was studied on the three neuropeptides(mammalian-,trout- and goldfish-neuropeptide γ)that were syntheized by the solid-phase method. Circular dichroism spectra showed that mammalian-,trout- and goldfish-neuropeptide γadopted an undered structure in buffer solution. In the presence od neutral and acidic liposomes, mammalian-and trout- neuropeptide γ also took a random structure. However, goldfish-neuropeptide γ took an α-helical structure in acidic liposomes. The intestinal motility response was investigated with carp interstines, guinea-pig ileums and rat duodenums. In case of carp intestine, contractine activity was as follows:goldfish-neuropeptide γ= trout- neuropeptide γ> mammalian-neuropeptide γ. On the other hand, the contracile activity of mammalian-neuropeptide γ was more potent than trout- and goldfish-neuropeptide γ in the guinea-pig ileums and rat duodenums. these results suggest that neuropeptide γs showed the species-specific activity.

목적 : 양성 갑상선 결절 환자에서의 PEI의 치료효과 및 부작용을 알아보고자 하였다. 방법 : 양성 갑상선 결절 환자 88명을 대상으로 초음파 소견에 따라 낭종성 결절, 복합성 결절, 고형성 결절 등 세 그룹으로 분류후 전체 및 각각에 대한 PEI의 치료효과 및 부작용을 조사하였다. 결과 : 양성 갑상선 결절 환자 88명을 PEI로 치료후 결절의 크기가 50%이상 감소한 경우는 전체 환자중 77.2%이었고 각 결절별로 살펴보면 고형성 결절에서 52.6%, 복합성 결절에서 72.4%, 낭종성 결절은 92.5%이었다. 부작용은 동통, 결절내 출혈, 감염, 결절의 누출등이 있었으나 대부분 무증상이었다. 결론 : PEI는 양성 갑상선 결절 환자증 적응증을 잘 살펴 고려해 볼 수 있는 치료법이라 생각되며 특히 낭종성 결절 환자에서 주사기에 의한 흡인후에 재발한 경우 일차적인 치료로 PEI를 고려해 볼 수 있겠다. Ultrasonography(US)-guided percutaneous ethanol injection (PEI) has been performed for the treatment of autonomous functioning thyroid nodules, thyroid cysts, & cold thyroid nodules. The author studied the efficacy of PEI in the treatment of benign cold thyroid nodules both solid and cystic (complex & pure). Eighty-eight euthyroid outpatients (age:44.2±13.9years, 75 women and 13 men) with benign cold thyroid nodules or simple thyroid cysts (69 with a single nodule and 19 with a prominent nodule within multinodular goiter) were includied in this study. After PEI, each subtype of thyroid nodules was divided into three groups in according to volume reduction complete response (90% or more of volume reduction), partial response (50% or more of reducton but below 90%), and failure (below 50% or increase in size) group. Overall response rates of PEI for benign thyroid nodules were complete 45(51.1%), partial 23(26.1%), failure 20(22.7%). In 20 cold solid nodules, complete response was observed in 6(30.0%), partial response in 5(25.0%), and failure in 9(45.0%). In 28 complex cysts, complete response was observed in 8(28.6%), partial response in 12 (42.9%), and failure in 8(28.6%). In 40 pure cysts, complete response was observed in 31(77.5%), partial response in 6 (15.0%), and failure in 3 (7.5%). Side effects comprised pain 8 (9.2%), intranodular bleeding 13 (14.6%), extracapsular leakage 1(1.1%), infection 1 (1.1%), increased size l(1.1%), and none 64(72.7%). PEI may prove a safe & effective tool for the therapy of cold thyroid nodules in selected cases and may be the treatment of choice of recurrent thyroid cysts. However, further investigation involving a larger number of patients and a longer follow-up is needed.
