  • Left coronary artery divides into anterior interventricular branch and circumflex branch. As both the arteries run in their corresponding grooves, an arteriovenous trigone is formed between conus arteriosus and left auricle called triangle of Brocq and Mouchet. The triangle base is formed by great cardiac vein. This study aims to describe the frequency of triangle and its type and relationship between various boundaries and content of triangle and to supplement the existing knowledge of clinicians. This observational and descriptive study was conducted on 40 formalin fixed cadaveric hearts in department of anatomy, Kalpana chawla government medical college. The triangle was found in 92.5% of specimen with most common type being closed (51.3%) which is followed by inferiorly open in 35.1%, superiorly open in 8.1% and completely open in 5.4% hearts. Most frequent content of triangle was median artery followed by diagonal branches of anterior interventricular and circumflex branches. The mean area of the triangle was 246.3 mm2. Relationship of vein with two arterial branches was either superficial or deep. The knowledge of different patterns of existence will be required for angiographic procedures. Further the triangle is a potential epicardial access route to left fibrous ring. Thus detailed knowledge of variations will help cardiologist to achieve better outcome in interventional procedures with minimal complications.

  • 간흡충의 병원성과 단백분해효소 활성도의 상관성을 밝히기 위하여 간흡충 추출물과 분비배설물 의 단백분해효소 활성도와 세포독성을 평가하였고 분비배설물에서 단백분해효소를 부분정제하고 생화학적 성질을 규명하였다. 여러 가지 단백분해효소 억제제를 사용하여 단백분해효소의 활성을 측정한 결과 간흡충에는 Rf값을 서로 달리하는 효소분획으로 되어있음이 관찰되었으며. 이러한 효소 분획은 azocasein을 기질로 한 활성부위 잔기 억제 실험에서 서로 상이한 활성부위잔기를 갖고 있음을 알 수 있었다. 간흡충 분비배설물의 세포독성은 단백질 농도를 $120\mu\textrm{g}/ml$까지 증가시키자 세포독성이 3배 증가했고. 이 효과는 NEM과 ntipain에 의해 억제되었다. 이 사실은 cysteine 단백 분해효소가 세포독성에 관여하는 것을 보여주고 있었다 이 단백분해효소는 최적활성치가 pH 7.5 이었다. 이 효소를 분비배설물로부터 23배 정제하였고 이때 회수율은 14.5%이었다. 부분정제한 단백분해효소의 분자량은 24 kDa이었다. 이 효소는 NEM, antipain에 의해 효소활성이 억제되었고, 동시에 세포독성도 억제되었다. 이 사실로부터 부분정제한 효소의 활성부위잔기는 cysteine이고 이 효소가 또한 분비배설되어 세포독성을 나타낸다는 것을 알 수 있었다.
