An axial-pattern flap can be transferred as the free-flap and has many merits over a random-pattern local flap. However, this has limitations of available vascular architecture and donor site. To overcome these problems, many types of prefabricated flaps have been designed using vascular bundles. It is possible to convert a random-pattern flap to a neovascularized axial-pattern flap by transferring a vascular pedicle. In an attempt to study the effects of prefabrication using vascular bundles, the survival rate between random-pattern flap and prefabricated axial-pattern flap was compared in this study. The rabbits were divided into two groups. The control group was consisted of the random-pattern flap and the prefabricated group was consisted of the prefabricated axial-pattern flap using femoral vascular pericles of rabbits. Femoral vascular pedicles were transferred under the 5x5cm lower abdominal flaps without any perivascular tissue. Three weeks later, random-pattern flaps were elevated without any axial vascular pedicle and prefabricated flaps were elevated based on the transferred femoral vascular pericles. The survival rate of the flaps in the control group and experimental group was 67.37% and 98.87% respectively. Based on the result of t-test there was significant difference between two groups. According to these results, it is concluded that prefabricated flap using transferred vascular pedicle was more effective than random-pattern flap. We think that this technique is versatile for wound repair and for use in other aspects of plastic and reconstructive surgery.

Augumentation rhinoplasty using autogenous cranial bone graft (outer table) can be used more successfully than other methods. In patients with congenital or posttraumatic severe saddle nose deformity and lateral deviation, cranial bone graft is an excellent method of augumentation. The advantages of cranial bone graft compared with traditional method of bone graft are summarized as follows; 1. Easy to reach donor site 2. Abundance of material 3. Little pain and functional disability 4. Shorter hospitalization period 5. Inconspicuous donor scar 6. No secondary deformity of donor site 7.Appropriate curvature can be obtained by proper selection of donor site. With the above advantages, we conclude that augumentation rhinoplasty using split cranial bone graft is a good method in correction of congenital or posttraumatic deformity of nose.

PURPOSE: It is not clear that the development of glomerular injury and aggravation by tumor necrosis factor alpha (TNF-alpha) is related to intrarenal or serum concentration of TNF-alpha. So, we studied the relationship between the concentration of TNF-alpha and aggravation of glomerular damage in the Henoch-Schonlein nephritis(HSN) and idiopathic nephrotic syndrome(INS). METHODS: We collected the sera and urines of 21 patients with Henoch-Schonlein purpura(HSP) and 22 patients with INS visited Chungbuk National University hospital from March 1998 to March 2001. The concentration of TNF-alpha in the sera and urines were measured by sandwich ELISA. RESULTS: Serum TNF-alpha levels in the HSP patients with renal involvement were significantly higher than those without renal involvement(P=0.009). But urine TNF-alpha levels have no correlation with renal involvement(P=0.088). In the HSN patients, proteinuria have a significant correlation with serum TNF-alpha levels(P=0.004) but less correlation with urine TNF-alpha levels(P=0.053). Otherwise, proteinuria have no correlation with serum TNF-alpha levels(P=0.763) but have a significant correlation with urine TNF-alpha levels(P=0.007) in INS. CONCLUSION: These result suggest that the serum concentration of TNF-alpha would be important to glomerular involvement in HSP. And, it is interesting that proteinuria shows a significant relation with serum TNF-alpha levels in the HSN, but with urine TNF-alpha levels in the INS. This means the major production of TNF-alpha may be originated by extrarenal inflammation in the HSN and by intrarenal tubulo-interstitial damage due to proteinuria in the INS.

Hepatoid carcinoma is a rare type of malignant tumor resembling hepatocellular carcinoma that arises in extrahepatic sites.(stomach, lung, ovary, pancreas, bladder and renal pelvis). Hepatoid carcinoma of the ovary is an extremely rare ovarian tumor, first described by Ishikura and Scully in 1987. Histologically it is important to differentiate this entity from other oxyphil tumors of the ovary as it requires aggressive treatment. We have experienced a case of hepatoid carcinoma of the ovary in 69-year-old postmenopausal woman, who has been treated with operation and adjuvant Taxol - cisplatin chemotherapy. We present this case with brief review of literatures.

Since introduction of venous flap in 1980, many experimental studies and clinical applications of various kinds of venous flaps were reported. Venous flap has the following advantages : (1) nonbulky and goo-quality of flap (2) long & large vascular pedicle (3) easy & rapid elevation of flap (4) no sacrifice of major arteries (5) a single operative field. But, we also have some disadvantages of difficult handling of the pliable veins and the tmcertainty of flap survival. For the better result we had to design the size of the flap larger than that of defect and increase the number of draining vein to reduce the postoperative edema of the flap. We have treated the defects of soft tissue of the hand using free arterialized venous flap from the flexor aspect of the forearm & had an excellent results.

A clinical study was performed on 940 cases of essential hypertension observed at Dept. of Internal Medicine of Seoul National University Hospital during a period of last seven years from 1971 to 1977. The followings were the results: 1. The incidence of hypertensive patients was 13.8% among all medical in-patients and 68.2% among all cardiac in-patients. 2. The highest occurence was observed in sixth decade and accounted for 34.2% of all cases and least occurence was in second decade of life which accounted for 0.6% of all cases. No difference was found in age distribution between both sexes. The male to female ratio was 1.2:1. 3. The mean value of blood pressure was 178.1+/-21.8/107.4+/-12.3 mmHg and tended to increase with age at least over the decades from second to seventh and there was tendency to decrease after the eighth decade. No paticular difference in blood pressure levels was found in both sexes. 4. The most outstanding symptom was headache which was found in 51.5% of all cases. Dizziness, dyspnea and palpitation were the next orders in frequency. There was a general trend of the the subjective symptoms which were more pronounced in younger than older patients. 5. Hypertensive retinopathy was found in 83.3% of all cases. Hypertensive retinopathy of K-W grade II was found in 36.1% of all cases and was the most frequent finding among the Keith-Wagener grades. Malignant hypertension of K-W grade IV was found in 4.2% of all cases and the largest numbers were between the fourth and fifth decade of life. 6. The abnormal retinal finding was found to be rather proportional to the blood pressure levels. 7. Albuminuria was detected in 56.2% of all cases and it was more frequent in male than in female patients. 8. The appearance of albuminuria seemed to have a close correlation with hypertensive retinal change and blood pressure levels. 9. Electrocardiographic abnormalities were associated in 71.9% of all cases. The most frequent association among electrocardiographic abnormalities was left ventricular hypertrophy which accounted for 45.2% of all cases. There was the reverse correlation between the normal electrocardiogram and degree of blood pressures. The finding of left ventricular hypertrophy and degree of blood pressures were closely correlated. 10. Cerebrovascular accident, renal failure, congestive heart failure and atrial fibrillation were four major complications. It was recorded in 26.5%, 10.4%, 5.4% and 2.0% of all cases respectively. The complications were common in men than in women. 11. Renal failure, congestive heart failure and myocardial infarction were closely corelated with hypertensive retinopathy.

BACKGROUND: White coat effect (WCE) and white coat hypertension (WCH) are relatively prevalent in clinical situation (20 - 57% of WCH in the hypertensive population). The aim of this study was to analyze the determinant factors of WCE. METHODS: A prospective study was carried out in outpatient clinic in a consecutive hypertensives without receiving pharmacologic treatment. Twenty-four hour ambulatory blood pressure monitoring (ABPM) was performed following more than two resting blood pressure (BP) determinations carried out with the interval of 1 - 2 weeks by mercury sphygmomanometer. WCE was calculated for systolic and diastolic BP as the difference between a clinic BP (CBP) and an average daytime ambulatory BP (ABP). WCH was defined as;BP in the clinic > or = 140/90 mmHg with a mean daytime BP by ABPM < or =137/< or =89 mmHg. RESULTS: 1) Two hundred thirty-five patients (mean age 49.7 years, females 74%) were studied. Thirty-seven percent in male and forty-six percent in female patients fulfilled WCH criteria. 2) CBP was significantly correlated to daytime ABP (systolic BP;r=.47, p<.001 and diastolic BP;r=.65, p<.001). 3) The magnitude of WCE was greater in the group of WCH (28.9+14.6/19.3+6.9 mmHg) than ambulatory hypertensives (15.1+15.7/13.0+8.2 mmHg) (p<.001). 4) The magnitude of WCE is significantly correlated with female (r2=.12, p<.001) and the stage of CBP according to JNC-V (r2=.23, p<.001) in systolic BP, the stage (r2=.08, p<.001) in diastolic BP, and the stage (r2=.09, p<.001) and weight (r2=.15, p<.01) in mean BP. CONCLUSIONS: The magnitude of WCE in essential hypertension diagnosed at the clinic is significantly correlated with female, the magnitude of clinic BP, and weight.

The ideal breast reduction should create beautiful breasts with limited scars. Unfortunately, no surgeon has ever been able to produce such a result. Most recent breast reduction techniques tend to produce minimal breast scars and avoid the classic inverted-T incision. The vertical mammaplasty can be used in mild to moderate cases of breast reduction, producing consistently good, stable results with limited scars. This technique uses adjustable preoperative markings, an upper pedicle for the areola, and a central breast reduction with limited skin undermining. The shape of the breast is created by suturing of the gland and does not rely on the skin. The adjunctive use of liposuction in fatty breasts can be considered safe and efficient. We have performed reduction mammaplasty using the vertical mammaplasty technique in 12 patients. Overall number and extent of complications were small, and patient satisfaction was high for this procedures. The advantages of vertical mammaplasty technique compared with other methods are as follows ; 1. The markings are adjustable to nearly all patients. 2. Stable contours are produced because the gland is strongly sutured. 3. Few postoperative complications occur. 4. Limited scars(only vertical scars) are created 5. The procedure is easy to learn and perform.
