To investigate the immunohistochemical expression of mutated p53 protein and bcl-2 protein in the cutaneous melanocytic lesion, 15 cases of compound nevus, 10 cases of congenital melanocytic nevus, 15 cases of primary malignant melanoma(4 cases less than 1.5 mm thick and 11 cases more than 1.5 mm thick), and 10 cases of metastatic malignant melanoma(7 cases in lymph node and 3 cases in soft tissue) were examined. All cases of compound nevi and of congenital melanocytic nevi showed no immunoreactivity for p53 protein. p53 protein overexpression was observed in 75%(3/4) wth primary malignant melanoma less than 1.5 mm thick, 81%(9/11) with primary malignant melanoma more than 1.5 mm thick, and 100%(10/10) with metastatic malignant melanoma. The difference in p53 protein overexpression was statistically significant between benign nevi and malignant melanoma(p<0.01). Bcl-2 protein expression was observed in 73%(11/15) with compound nevus, 70%(7/10) with congenital melanocytic nevus, 75% (3/4) in primary malignant melanoma less than 1.5 mm thick, 54%(6/11) with primary malignant melanoma more than 1.5 mm thick, and 40%(4/10) with metastatic malignant melanoma. These findings suggested that mutation of p53 gene may be an important mechanism in the development of malignant melanoma. Although bcl-2 protein was expressed in cutaneous melanocytic lesion, no correlation was found between p53 protein and bcl-2 protein expression in malignant melanoma.

BACKGROUND: Cold blood cardioplegic solution has been used to protect myocardium during open heart surgery with the hypothesis stating that it provides more oxygen supply to myocardium compared to crystalloid caridoplegic solution. We repeatedly infused cold blood cardioplegic solution to achieve myocardial protection. We biopsied a small portion of papillary muscle of patients with mitral valve replacement or double valve replacement during aortic cross-clamp time and evaluated the method of myocardial protection through the observation of changes in ultrastructure. We then analysed the relationship between changes in ultrasructure and peak postoperative CK-MB value and SGOT value. MATERIAL AND METHOD: We report observation on changes of myocardial ultrastructure, postoperative CK-MB and SGOT, and electrocardiogram in 31 patients who underwent cardiac operation. There were 11 males and 20 females, and they ranging in age from 28 to 69 years (mean score was 2.08+/-0.560, it was 2.37+/-0.558 at 40 minutes, and it was 2.36+/-0.523 at 70minutes. Mitochondrial score increased significant at 40 minutes. Mean value of postoperative peak CK-MB and SGOT were 37.3+/-17.061IU, 144.5+/-125.5IU respectively. We were not able to find any new Q were in EKG after the operation. There was no significant relationship between myocardium mitochondrial score and mean value of postoperative peak CK-MB and SGOT. CONCLUSION: In conclusion, with this study the cold blood cardioplegic solution was incomplete in preserving ultrastructure of myocardium even with satisfactory results in serum enzyme and EKG evaluation.

BACKGROUND: The aim of this study was to investigate the relationships between left ventricular ejection fraction (LVEF) and mortality and neurologic outcomes with post-cardiac arrest syndrome (PCAS) after out-of-hospital cardiac arrest (OHCA). METHODS: Patients with PCAS after OHCA admitted to the intensive care unit between January 2014 and December 2015 were analyzed retrospectively. RESULTS: total of 104 patients were enrolled in this study. The mean age was 54.4 ± 15.3 years, and 75 of the patients were male (72.1%). Arrest with a cardiac origin was found in 55 (52.9%). LVEF < 45%, 45-55%, and > 55% was measured in 39 (37.5%), 18 (17.3%), and 47 (45.2%) of patients, respectively. In multivariate analysis, severe LV dysfunction (LVEF < 45%) was significantly related to 7-day mortality (odds ratio 3.02, 95% Confidence Interval 1.01-9.0, p-value 0.047). CONCLUSIONS: In this study, moderate to severe LVEF within 48 hours after return of spontaneous circulation was significantly related to 7-day short-term mortality in patients with PCAS after OHCA. Clinicians should actively treat myocardial dysfunction, and further studies are needed.

The incidence of cervical pregnancy and the number of combined intrauterine pregnancy and ectopic pregnancy seems to be increasing. So the possibility of heterotopic pregnancy should always be considered by every gynecologist, especially those who treat infertility problem. We experience a case of a heterotopic pregnancy coexisting of an intrauterine pregnancy and a cervical pregnancy after in-vitro fertilization and embryo transfer, and was successfully managed by transcervical evacuation and resulted in a normal intrauterine pregnancy. Here we present the case with review of literatures.

The objective of this paper is to introduce the schematic protocol of radiofrequency (RF) ablation for the treatment of varicose veins. Indication: anatomic or pathophysiologic indication includes venous diameter within 2-20 mm, reflux time > or =0.5 seconds and distance from the skin > or =5 mm or subfascial location. Access: it is recommended to access at or above the knee joint for great saphenous vein and above the mid-calf for small saphenous vein. Catheter placement: the catheter tip should be placed 2.0 cm inferior to the saphenofemoral or saphenopopliteal junction. Endovenous heat-induced thrombosis > or =class III should be treated with low-molecular weight heparin. Tumescent solution: the composition of solution can be variable (e.g., 2% lidocaine 20 mL+500 mL normal saline+bicarbonate 2.5 mL with/without epinephrine). Infiltration can be done from each direction. Ablation: two cycles' ablation for the first proximal segment of saphenous vein and the segment with the incompetent perforators is recommended. The other segments should be ablated one time. During RF energy delivery, it is recommended to apply external compression. Concomitant procedure: It is recommended to do simultaneously ambulatory phlebectomy. For sclerotherapy, it is recommended to defer at least 2 weeks. Post-procedural management: post-procedural ambulation is encouraged to reduce the thrombotic complications. Compression stocking should be applied for at least 7 days. Minor daily activity is not limited, but strenuous activities should be avoided for 2 weeks. It is suggested to take showers after 24 hours and tub baths, swimming, or soaking in water after 2 weeks.

We experienced a case of spontaneous rupture of subcapsular hematoma of liver that was treated with conservative method. So, we present the case with a brief review of literatures as first report in Korea.
