초록
만손열두조충의 스파르가눔(흰쥐에서 적출한 r-스파르가눔, 뱀에서 적출한 s-스파르가눔)과 성충을 재료로 하여 젖산탈수소효소와 말산탈수소효소의 조직내 분포 및 동위효소의 특징을 효소조직화학적 방법과 전기영동뎁으로 조사하였다. LDH와 WH는 외피하근층에서 강한 활성이 나타났으며, 실질조직(parenchyma)에서는 약하게 나타났다. 그러나 nH는 스파르가눔의 외피조직 에서도 활성이 나타났으나 성충의 외피조직에는 나타나지 않았다. LDH의 동위효소 유형은 5-스파르가눔, s-스파르가눔과 성충에서 각각 2개, 4개, 2개가 분리되었고, 45 kDa의 분회이 공통적으로 주분획이었으며 sinH의 동위효소는 5-스파르가눔, r-스파르가눔과 성충에서 각각 2개, 3개 4개의 분획이 분리되었고, IEF에 의해 성충에 존재하는 4개의 tmH 동위효소 분획의 등전점(Pl)은 각각 6.0, 6.5, 6.7, 7.1이었으며, 이 중 6.0이 주분획이었다. 또 최적 pH는 7이나 활성 범위가 pH 6 ~8이었고. 최적온도는
This study investigated the enzyme histochemical localization and characteristics of lactate (LDH) and malate dehydrogenase (MDH) related with the oxidation-reduction metabolism in the sparganum and adult of 5. erinacei. By enzyme histochemical assay, activity of LDH was strong in the tegument and subtegumental muscle layers of the adult and sparganum. Activity of MDH was strong in the tegument of the sparganum and subtegumental muscle layers of the adult. However it was weak in the tegument of the adult. By electrophoresis, 45 kDa band was major and common in LDH of adults and spargana. The 150 kDa molecule was the major and common band in MDH of adults and r -spargana (from experimentally infected rats) . By isoelectrofocusing, isoelectric points (Pl) or 4 MDH isogyme from adult worm were 6.0.6.5, 6.7 and 7.1, respectively. Pl 6.0 was the major band. The active range of pH for MDH was about pH 6-8 and the optimum pH was pH 7 The effective temperature on the MDH was about
