  • In this paper, optimal block designs for complete diallel crosses are proposed. These optimal block designs are constructed by using triangular partially balanced incomplete designs derived from symmetric balanced incomplete block designs. Also, it is shown that block designs for complete dialle crosses derived from complementary designs of triangular designs are optimal block designs.

  • In this paper, optimal block designs for complete diallel crosses are proposed. These optimal block designs for estimating general combining abilities are constructed by using balanced incomplete block designs and nested balanced incomplete block designs. Also, the efficiency of the optimal block design obtained through this method is reported in table.

  • 완전이면교배를 블록화하는 매개디자인으로는 일반적으로 부분적으로 균형된 불완비 블록계획을 사용한다. 이때 블록화하는 매개디자인으로 삼각형 PBIBD를 사용하기 위해서는 대응되는 모수를 갖는 삼각형 PBIBD를 찾아야 한다. 특정한 모수를 갖는 균형된 불완비 블록계획의 쌍대계획이 삼각형 PBIBD가 되는 성질을 이용하면 삼각형 PBIBD를 새로 찾아야 하는 번거로움 없이 블록 완전이면교배를 설계할 수 있다. 이를 만족하는 블록 완전이면교배를 설계하는 방법과 디자인을 제시하였다.

  • There appears some conduction defects frequently after total correction of Tetralogy of Fallot. Common defect is right bundle branch block due to surgical intervention. We experienced complete A-V block which occured 3 months later after total correction of Tetralogy of Fallot in a 8 year old boy. The patient was completely free of any A-V block after the operation for 3 months, and sudden onset of A-V block with coupled premature ventricular contractions resulted him in shock state during the attack of severe bronchopneumonia for 4 days prior to the second visit. Emergency implantation of Cordis demand type temporary pacemaker was necessary to control the complete heart block with bradyarrhythmia and frequent ventricular fibrillation. Permanent cardiac pacemaker was implanted two weeks later as indicated with Cordis Stanicor lambda demand pacemaker, and the patient was discharged uneventfully on the 8th post implantation day with the heart rate of 72/min. Another 3 months after the implantation, the patient was transported to this hospital as dead on arrival after an accidental fall from a 2 meter height, and all possible cardiopulmonary resuscitation was performed for 60 minutes at the emergency room in vain. Autopsy was done to find out the cause of sudden death and the etiology of complete heart block. Microscopic focal infarctions with scar formation were noted along the course of conduction system in the interventricular septum, which might be the main cause of complete heart block during the attack of severe bronchopneumonia complicated with acute bacterial endocarditis. The tip of the pacemaker wire was slipped from the granulation scar at the apex of the right ventricular cavity, and this might be the direct cause of pacing failure and death.

  • This clinical case reports the effect of Chilgi-tang, a kind of traditional Korean herbal medicine, on $3^{rd}$ degree AV block patients also known as complete heart block. Complete heart block caused by degeneration of electrical conduction system of heart may result in weakness, dizziness, syncope, etc. Two clinical cases reported herein are diagnosed as $3^{rd}$ degree AV block caused by psychological stress with chief complaints of syncope and dyspnea respectively. The chief complains of cases cured remarkably after Chilgi-tang medication. In one case, $3^{rd}$ degree AV block was disappeared. In conclusion, we suggest that Chilgi-tang can be a potential treatment for complete heart block due to psychological stress.

  • Introduction: This study reports the effect of herbal medicine (Samulanshin-tang-gamibang) and acupuncture on complete atrioventricular (AV) block. Case presentation: A 63-year-old female with complete AV block was experiencing dyspnea, palpitation, dizziness, headache, bradycardia, and insomnia, and she was treated with Samulanshin-tang-gamibang and acupuncture for 12 days. To evaluate the treatment, a numeric rating scale (NRS) and the New York Heart Association (NYHA) functional classification was used. The patient's NRS scores decreased from 6 to 2 for dyspnea and palpitation and from 5 to 1 for dizziness and headache. Her NYHA Class improved from Class II to Class I. No side effects were observed during treatment. Conclusion: This study suggests that herbal medicine and acupuncture may be effective in relieving symptoms caused by complete AV block. However, the long-term effects of the treatment were not observed, and so further studies are still needed.

  • Arrhythmias are complications of tunneled cuffed hemodialysis catheter insertion. Most complications associated with arrhythmias occur during guide-wire access, where the guide wire can cause traumatic damage to the conduction system of the heart. Conducting system injury in tunneled cuffed hemodialysis catheter insertion often involves the right bundle, causing right bundle branch block (RBBB). Transient RBBB with sinus rhythm is not usually accompanied by abnormal vital signs. However if patients already have left bundle branch block (LBBB), new onset RBBB can cause complete atrioventricular block (AVB), which can lead to fatal complications requiring invasive treatment. We report on a patient with LBBB who developed complete AVB during hemodialysis catheter insertion.

  • Total spinal block is used as final choice for chronic intractable pain which doesn't respond to other treatments. A 35 years old male patient was admitted to pain clinic due to severe cramping and throbbing pain of whole body, especially left lateral side since 1980. The result of cervical and lumbar epidural block was not good enough, so we decided to try total spinal block. At first, C7-T1 interspace was punctured and 2% mepivacaine 20 ml was injected, but the result was not satisfied. Next day, L3-4 interspace was punctured and 1.5% mepivacaine 40 ml was injected. The sensory block level was C6 and pain score on Visual Analog Scale, was changed from 9 to 4. In both trials, actually even though they were not complete total spinal block, the effect was good enough. If complete total spinal block had been accomplished, better result might be obtained in this chronic intractable pain.
