Acaricide effect against Tetranichus urticae, Myzus persica, Spodoptera litura and Plutella xylostella with the Ginkgo biloba leaves extracts was reviewed. This result was motality 74.3%, 88.7% respectively, after tretment 24hr, 72hr about $80^{\circ}C$ water extract(GLW80, 1%) of Tetranichus urticae and the insecticide took effect showed its effect in some 50% against the other three. But, motality of Tetranichus urticae against 10% GLW80 showed its 90.6%, 98.3% after tretment 24hr and 48hr.

The results of the clinical observations on the 158 cases of the mitral valvular heart disease treated at the Department of Thoracic and Cardiovascular Surgery, Masan Koryo General Hospital from June, 1986 to December, 1991 were as follows; 1. There were 50 men and 108 women with sex ratio 1: 2.2. 2. The age of patient varied widely from 13 years to 65years. 3. The preoperative functional level accoridng to the NYHA classification were class II, III, IV in 18%, 67%, 15%. 4. All 158 patients were operated on under direct vision using extracorporeal circulation, mitral valve replacement in 118 cases, mitral and aortic valve replacement 40 cases. 5. The follow up period was between 2 months and 65 months postoperatively. [mean 30.1 months] 6. The early operative motality was 5.7%[9 cases], late motality was 4%[6 cases]. 7. The cardiothoracic ratio in the chest X-ray decreased at the 6th month postoperation. [pre-op: 0.60$\pm$0.07, post-op: 0.56$\pm$0.06 p<0.01]

Purpose: Many hemostatic agents and dressings have been tested with variable degree of success. Chitosan has a positive charge, it attracts red blood cells, which have a negative charge. Our goal is to test the efficacy of new developed chitosan-based hemostatic materials in providing durable hemostasis in a high-flow arterial wound model. Methods: We compared each group with SD rats motality tests and in vitro blood compatibility test by blood clotting index (BCI). We devided the SD rats into 6 groups (N =15) by type of hemostatic agents. A: 100% nonwoven chitosan (degree of the deacetylation: 90%). B: 50% N-acetylation on nonwoven of chitosan gel (degree of the deacetylation: 50%). C: 60% N-acetylation on nonwoven of chitosan ge (degree of the deacetylation: 40%)l. D: Cutanplast$^{(R)}$. E: HemCon$^{(R)}$ F: Gauze. In vivo test, a proximal arterial injury was created in unilateral femoral arteries of 90 anesthetized SD rats. Each materials was made same size and thickness then applied to the injury site for 3 minutes. In vitro test, we compared each group with BCI in human blood. Results: In vivo test, group A showed lower motality rate of 46% than any other groups, Group B and C showed lower motality rate of 60% than group D and E's motality rate of 66%. In vitro test, BCI of group A ($30.6{\pm}1.2$) and B ($29.3{\pm}1.0$) were showed nearly about group D ($29.1{\pm}1.8$) and E ($27.4{\pm}1.6$). Group C ($37.1{\pm}2.0$) showed higher BCI than group A and B, it means group C decreased blood clotting. Conclusion: In conclusion, this study suggests a newly developed chitosan-based hemostatic materials induced durable hemostasis and increased blood clotting, and are considered as effective biologic hemostatic agents.

청평내수면연구소에서 발생한 쏘가리 치어의 대량 폐사 원인을 조사하였다. 병어로부터 분리된 원인균은 생화학적 및 생리학적 특성에 의해 Aeromonas hydrophila (A. hydrophila)로 동정되었다. A. hydrophila을 쏘가리 치어(3-4 g)에 침지, 경구투여, 근육피하 주사 및 세균이 분비한 가용성 세포의 산물 주사 등 여러 가지로 감염 실험을 하였다. 그 결과 근육피하 주사 실험군에 있어서는 다른 감염 실험에서보다 높은 폐사율을 보였고, 가용성 세포외 산물도 고농도 ($8{\times}10^9$ cfu/ml)로 처리한 어류에서는 3-6시간 이내에 모두 폐사되었다. 이러한 결과는 쏘가리 치어가 A. hydrophila에 감수성이 높은 것을 보여주었다.

Complications of diabetes increase morbidity and motality and decrease quality of life. Recently. UKPDS has been reported that strict regulation of blood glucose. hypertension and hyperlipidemia could decrease complications of type 2 diabetes. This study evaluated use of hypoglycemic agents, control of blood glucose. frequency of complications and preventive management at a local 2ndary hospital in Korea. (omitted)

Effusive-constrictive pericarditis is a very rare disease in infants but has high motality rates when not treated. There were some reports of pericardial constriction associated with intrapericardial abscess that led to pericardiectomy. The patient was admitted due to fever, cyanosis, and abdominal distension. We treated the patient with antibiotics and pericardiostomy but the symtoms did not improved, therefore, pericardiectomy was perfomed immediately. The patient with effusive-constrictive pericarditis was immediately relief on the symptoms and the treatment was successful.

The paper aimed to review the influences of ginseng on the metabolism of foreign substances and on the activity of hepatic drug metabolizing enzyme system in mouse or rat liver. It has been known that ginseng components reduces the motality rates and the toxic effects induced by foreign materials. Chronic pretreatment of mouse or rat with ginseng extract fractions or saponin caused the increase in the metabolism of foreign materials and the activity of drug metabolizing enzymes, such as cytochrome $P_{450}$, NADPH cytochrome C reductase and glucuronyl S-transferase in liver. Thus, it may be concluded that decrease in toxic effect of foreign substances by ginseng pretreatment may be partly related to the induction of drug metabolizing enzymes in liver.

During the period of June 1976 October 1980 131 cases of Open heart Surgery was performed at the National Medical Center in Seoul under the extracorpocal circulation. 77 cases were congenital heart disease and 54 were acquired heart disease. The age of the patients ranged between 2$\frac{1}{2}$ and 51 years. For all patients partial hemodilution technique and moderte hypothermia was used during extracorporeal circulation and cardioplegia was done for myocardial protection since April 1978. 41 of congenital cases were non-cyanotic group and 1 case died. 36 of congenital cases were cyanotic group and revealed very high mortiality rate (16 death, 39%). 53 of acquired cases were cases of valvular heart disease, 34 mitral (3 death), 1 aortic, 4 mitral with aortic 12 mitral with tricuspid (3 death), 2 triple valves (2 death), and revealed mortality rate of 15.1% (8 death). 1 of acquired cases were left atrial myxoma. There were 25 cases of operative death and over all motality rate was 19.1%.

Esophageal foreign bodies are common problems in the part of otolaryngology department, and may cause severe complications such as esophageal ulceration, esophageal perforation, periesophagitis, tracheoesophageal fisula, pneumothorax and pyothorax. Therefore, early diagnosis and intervention is needed to reduce morbidity and motality. But, calcification of the laryngeal cartilages may masquerade as foreign body in some patients with a history of foreign body ingestion. Recently, We experienced a case of calcification of thyroid cartilage which was misunderstood as an esophageal foreign body and report this case with a review of literatures.
