Anomalous origin of right pulmonary artery from ascending aorta is a rare congenital heart disease. We experienced a case of anomalous origin of right pulmonary artery from ascending aorta with associated patent ductus arteriosus and patent foramen ovale, which was diagnosed by angiocardiography and cardiac catheterization. The ductus was ligated just before bypass, and a Dacron-graft with a diameter of 16 mm was interpolated posteriorly to the aorta between the right pulmonary artery and the pulmonary trunk. The postoperative course was uneventful. The right heart catheterization and right ventriculography performed on postoperative twelfth day revealed widely patent anastomotic site between the right pulmonary artery and the pulmonary trunk without residual stenosis. She was discharged on postoperative fourteenth day.

Ranicef\ulcorner[Cefpimizole sodium] is a new semisynthetic cephalosporin C derivative, was administered to 30 patients with empyema thoracis to evaluate its efficacy from Nov. 1989 to May 1990 at Department of Thoracic & Cardiovascular Surgery, Dongsan Medical Center, Keimyung University. The results were as follows. 1. The clinical efficacy of therapy was excellent in 15 cases, effective in 11 cases and failure in 4 cases. The effectiveness rate was 86.7%, respectively. 2. Among 30 cases organisms were cultured in 19 cases and 24 clinical strains were isolated. \ulcorner-hemolytic streptococcus[5], S. epidermidis[4], Pseudomonas aeruginosa[3], E. coli[3 of 5 cases], S. aureus[3 of 4 cases] and Klebsiella pneumoniae[1 of 2 cases] were effective to Ranicef\ulcorner 3. Abnormal clinical values, a decrease in platelet was observed in 3 cases and slight increases of s-GOT/GPT in 2 cases. But they were not so severe that they improved without. There were two cases of mild gastrointestinal symptom.

토양에서 추출하여 이화학적 성질을 잘 규명한 풀빅산과 카드뮴과의 착화합 반응을 풀빅산의 서로 다른 농도와 다양한 pH 조건하에서 이온 선택성 전극을 이용하여 연구하였다. 결합상수는 Scatchard Plot에 근거한 연속분포모델을 이용하여 구하였다. 이 모델은 결합자리의 성격에 대한 정보 없이도 자연산 유기 고분자의 결합 자리의 다양성을 잘 반영해 줄 수 있다. $logKi(\mu)$의 평균값은 pH가 높아질 수록(pH 4.0: ${\mu}=3.79{\pm}0.74\;l\;mol^{-1}$; pH 6.0: ${\mu}=4.51{\pm}0.78\;l\;mol^{-1}$) 풀빅산의 농도가 묽어질 수록 ([FA] = 50 $mgl^{-1}:{\mu}=4.16{\pm}0.60\;l\;mol^{-1};[FA]=151\;mgl^{-1}: {\mu}=3.75{\pm}0.56\;l\;mol^{-1}$)증가하는 경향을 나타냈다. 가장 강한 결합자리의 결합에 대한 결합상수인 고유결합상수(logKint)는 pH 4.0과 pH 5.0에서 4.72 l $mol^{-1}$이었으며 pH 6.0에서는 6.03 l $mol^{-1}$으로 증가하는 경향을 나타냈다. The complexation of cadmium(II) with a well characterized local soil fulvic acid was investigated at different solution pH and fulvic acid concentration using ion selective electrode. The stability constants were determined using a continuous distribution model based on Scatchard Plot; this model takes into consideration the diversitv of cation binding sites on a naturally occurring organic macromolecules even if the nature of the binding sites may not be known. The mean value of $logKi(\mu)$ was found to increase at higher pH(pH 4.0: ${\mu}=3.79{\pm}0.74$ l\;mol^{-1}; pH 6.0: ${\mu}=4.51{\pm}0.78$ l\;mol^{-1}$), and in more dilute fulvic acid concentration([FA] = 50 mgl$^{-1}: {\mu}=4.16{\pm}0.60$ l\;mol^{-1}; [FA]=151 mgl$^{-1}:{\mu}=3.75{\pm}0.5\;l\;mol^{-1}$). The intrinsic constant(logKint) for binding at the strongest site was measured to be around $4.72\;l\;mol^{-1}$ at both pH4.0 and 5.0, but was found to be increased to $6.03\;l\;mol^{-1}$ when pH was 6.0.
