M-mode, pulsed Doppler and Doppler color flow mapping, in addition to two-dimensional echocardiography, have greatly improved imaging of the fetal heart through identification of abnormal cardiac anatomy and rhythm in utero. The early detection of cardiac disturbance in utero permits alteration in obstetric management such as delivery in a high-risk center for optimal neonatal care and/or decision in optimal delivery time. We report two cases of the neonatal arrhy-thmia which were observed by fetal echocardiography. In the first case, female baby showed neonatal arrhythmias including tachycardia and brady-cardia until 3 days after birth, and then turned to bradyarrhythmia due to non-conducted atrial bigeminy. These events lead us to review the fetal echocardiographs of the patient carefully. Premature atrial contractions were observed in her fetal echocardiography. At 2 months after birth, the patient's electrocardiogram showed normal sinus rhythm. Severe neonatal bradycardia of the second case was due to congenital complete heart block, identified clearly by electrocardiogram after birth. This case also showed complete heart block in her fetal echocardiography. After insertion of the temporary pacemaker, cardiomegaly was improved. Both the neonate and the mother had positive anti-SSA/Ro autoantibody. But any other symptoms and signs of neonatal lupus did not appear in the neonate. Patient's mother also did not show any symptoms and signs of systemic lupus erythematosus. Since the prognosis depends upon the cause of bradyarrhythmia in fetus and neonates, differential diagnosis is important in obstetric management and optimal neonatal treatment.

Fetal cystic hygroma is a rare congenital malformation of the lymphatic system appearing as a single or multiloculated fluid-filled cavity, most often in the neck. A case of fetal nuchal cystic hygroma was diagnosed by Ultrasonography at 22 weeks of gestation and the diagnosis was confirmed at autopsy. We present the case with a brief review of literature.

Normal C3H/HeN strain mice exposed to low-dose ultraviolet radiation(4 * 400 J/m) demonstrated a reduction in contact sensitization potential which locaiized to the skin area of direct UVR exposure(local suppression), where high-dose exposure of UVR(1*30.000 J/m) caused systemic suppression of CH induction, regardless of the application site of 2,4-dinitro-l-fluorobenzene(DNFB). There seemed to be two different mechanisms that are responsible for CH reaction induced by UVR. One of them, local suppression of low-dose UVR resulted from blocking the afferent phase of immune response by the functiona] inactivation of the epidermal Langerhans cells ; it was associated with lack of CH effector cells in the peripheral lymph nodes, an enhanced splenic suppressor cell acitvity, and could not be reversed by indomethacin treatment. The other, systemic suppression of high-dose UVR was mediated by enhancement of prostaglandin E(PGE); it was associated with prevention of the egress of effector cells within the regional lymph node which was caused by blocking the efferent lymphatics, and elevated plasma level of PGE. And depressed CH response was reversed when treated by indomethacin.

PURPOSE: To analyse the risk factors for recurrence of hemangiomas in extremities after surgical treatment and to compare with those of trunk. MATERIALS AND METHODS: 120 cases of hemangioma with surgical treatments from June 1998 to September 2009 were analysed. 53 cases with surgical treatment on trunk in the same period were set to be the control group. We analyze several factors: age, location, site, size, histologic types and correlation between recurrence and each risk factor using logistic regression analysis. RESULTS: Recurrence rate was 11.7% in extremities and 9.4% in trunk. There were no correlation between recurrence and age, site, size, histologic type. But, there was stastically significant correlation between recurrence rate and location, especially hand, forearm, feet in extremities and head and neck in trunk. CONCLUSION: Recurrence after surgical treatment of hemangioma is highly prevalent in anatomical location such as, hand, foot and forearm those are difficult to achieve complete resection because of close to neurovascular structures. Careful observation should be needed owing to incomplete resection can occurs recurrence.

Plain chest films are the most useful modality in diagnosis of primary lung cancer, but it is difficult tointerpret the radiologic findings by histological types. Authors reviewed chest films of 324 cases ofhistologically confirmed primary lung cancer from Jan. 1974 to April 1982 at Seoul National University. The resulsare as follows; 1. Incidence was most common in the 6th decade as 34.4%. Male to female sex ratio was 3.8:1 andthere was no sex difference in Adenocarcinoma. 2. Distrubution of histologic types of primary lung cancer asfollows; Squamous cell Carcinoma 50.6%, Small Cell Carcinoma 22.5% lange Cell Carcinoma 9.3% Bronchegenic adenocaranoma 10.5% Bronchioloalveolar Cell Carcinoma 1.9%. Adenosquamos Carcinoma 0,6%, Carcinoid Tumor 0.3%, AdenoidCystic Carcinoma 0.3%. 3. Radiologic findings by histologic types as follows; a) Squamous cell carcinoma commonlypresent as collapse(51.8%) peripheral mass (40.8%), pneumonitis(37.2%), hilar involvement(34.8%), and in singleabnormality, peripheral mass (44.4%). b) Small cell carcinoma commonly present as hilar involvement(78.1%),mediastinal wideing or mass (53.4%) and in single abnormality, hilar involvement(58.3%). c) Large cell carciomacommonly present as hilar involvement(50%) pneumonia(46.7%), collapse (40%), peripheral mass(36.7%) and in singleabnormality, large peripheral mass (33.3%). d) Bronchogenic Adenocarcinoma commonly present as peripheralmass(44.1%), collapse (41.2%), pleural effusion (35.2%) and in single abnormality, peripheral mass(50%). e)Solitary peripheral mass commonly present as lobulation(48%) and spiculated margin (51%), but no specific findingsby histologic types. Cavitary formation was most common in Squamous cell carcinoma.

Transcatheter embolization using absolute ethanol is a widely used technic in interventional radiology. Butits mechanism of action and embolization effect on various infusion speed are poorly understood. Authors performedan experimental study in rabbits to doccument the effect of absolute ethanol onvarious infusion rate. The resultsare as follows; 1. In high speed infusion group(>0.1ml/sec. n=13), 11 cases showed peripheral obstruction and 2 cases showed central obstruction. 2. In low speed infusion group(<0.1ml/sec. n=12), 4 cases showed peripheralobstruction and 8 cases showed central obstruction (p<0.02). 3. On follow-up angiography performed 4 weeks later(n=8), no demonstrable significant differences are found between two groups.
