Serum lipoprotein patterns were studied in 78 normal persons and in the following patients; 79 patients with hypertension, 21 patients with cerebrovascular accident, 10 patients with myocardial infarction, 18 patients with diabetes mellitus, 10 patients with nephrotic syndrome, and 10 patients with chronic renal failure. The serum lipoproteins were separated by electrophoresis on cellulose acetate which gives high resolution of chylomicron, beta-lipoprotein, pre-beta-lipoprtoein and alpha-lipoprotein. Lipoproteins were stained by Oil Red O saturated in 60% ethanol, and each fraction was cut and eluted for spectrophotometric determination. The results obtained are summarized as follows. 1. In normal Korean, serum alpha-lipoprotein showed decrement with aging, while serum beta-lipoprotein increasesd with aging, but the difference was not statistically significant. No significant alteration by sex in serum lipoprotein patterns were observed. Pre-betalipoprotein was observed in 28.6% of normal Korean under the age of 30, and about 50% of normal Korean over the age of 30. 2. Serum beta-lipoprotein was higher significantly in the patients with myocardial infarction than in normal control subjects. 3. Serum beta-lipoprotein in the patients with essential hypertension was significantly higher than in normal control subjects. Serum lipoprotein patterns were, however, not statistically different by both sex and age in essential hypertension, It was observed that increased serum beta-and pre-beta-lipoprotein in essential hypertension was closely related with the intensity of albuminuria. 4. No significant difference in the serum lipoprotein patterns between normal control and the patients with cerebrovascular accident was observed. 5. In patients with diabetes mellitus, marked increase in the serum beta- and pre-beta-lipoprotein was observed. 6. in the patients with nephrotic syndrome, the increase in the serum beta-and pre-beta-lipoprotein was marked, and markedly increased pre-beta-lipoprotein was the case in more than half of the patients as compared to the other groups. 7. No difference was observed in the composition of polar lipids between the patients with various diseases (essential hypertension, diabetes mellitus and cerebrovascular accident) and normal person.

Since the male sterilization (vasectomy) has been performed on a large scale as an accepted family planning in Korea on 1980s and this, in turn, has been followed by an increase in the number of patients requesting vasovasostomy. We studies 1000 consecutive cases of vasovasostomy performed from January 1975 to July 1995 in Pusan National University Hospital. In this report, we are going to present serial studies of vasovasostomy through which we attempted to find out what factors are of impotence in influencing the successful outcome of vasovasostomy operation. We inquired the operative results data through the questionnaire and telephone interview with survey of medical records. A total of 259 cases was excluded due to the loss of follow-up. The overall patency and pregnancy rates of 741 cases were 86.9% and 51.1%, respectively. The age of man at the time of anastomosis ranged from 23 to 57 years old with an average of 34.9. The most frequent reason for requesting vasovasostomy was the desire to have more children (43.4%). The average obstructive interval was 60.6 months with range from 1 to 264 months. If the obstructive interval had been less than S years patency rate was 92.4% and pregnancy rate 64.8%, but 6 years or more 84.1% and 48.5% p<0.01, p<0.01). Patency and pregnancy rates according to intraoperative vas fluid were 93.1% and 62.8% for presence and 83.7% and 53.1% for absence p<0.01, p<0.05). Patency and pregnancy rates according to histologically proven sperm granuloma at vasectomy site were 87.7% and 49.2% for presence and 86.9% and 50.6% for absence (p>0.05, p<0.05). Patency and pregnancy rates were not significantly different between microscopic standard vasovasostomy (88.4%, 64.3%) and modified vasovasostomy (89.5%, 56.3%)(p>0.05, p>0.05). Both patency and pregnancy rates according to level of anastomosis were 89.8% and 59.8% in cases of straight vas and 91.5%, 60.1% in cases of convoluted vats (p>0.05, p>0.05). Patency and pregnancy rates according to the kind of suture materials were 91.5% and 56.2% for absorbable, 91.0% and 64.2% for non-absorbable and 93.3% and 53.3% for absorbable plus non-absorbable, respectively 0>0.05, p<0.05). Thus it is suggested that the important factor influencing the success rate of vasovasostomy is the interval of obstruction and nasal ooze with surgical skills.

"Mig is a gamma interferon-inducible T cell chemoattractant that is a member of the chemokine family of cytokines. In order to gain a better understanding of the molecular mechanisms that regulate expression of the Mig gene, we have characterized the Mig gene and compared its structure and regulatory sequences with that of its ciosest IP10 gene. The genomic organization of the Mig gene reveals three introns that interrupt the transcribed sequence into four functional domains with a single ""CAT""- and ""TATA""-like structure. Primer extension analysis was used to identify the transcriptional initiation site that is located 50 bp upstream to the methionine codon that begins the long open reading frame. Comparison of the intron-exon structure of this gene to the gene for IP10 establishes that both genes are interrupted in precisely the same positions within homologous codons. The similarity of the intron-exon structure of the Mig and IP10 genes further support the hypothesis that Mig and IP10 genes have evolved from a common ancestral gene by gene duplication. The 5'-flanking region of Mig gene shows no overall sequence similarity with that from its closest IP10 gene whose production is also affected by gamma interferon. However, there are regions including a sequence with similarity to the NFxB binding site, AP-1 binding site, and ISRE. The r-RF-1 binding site is well conserved from -204 to -194 from the transcription start site in the Mig gene. Given the importance of IFN-r for effective immunity in tuberculosis and induction of Mig and IP10 genes in macrophages by IFN-r, we demonstrated induction of the genes Mig and IP10 with different message levels in the THP-1 human monocytic cell lines stimulated with whole M. tuberculosis. Despite the very similarity in genomic organization and the overlap in biological activities between MIG and IP10, our data described herein further support the suggestion that these chemokines rnay role nonredundantly in vivo. Moreover, our studies done on the Mig gene should provide the structural framework for future studies and begin to dissect cis-acting DNA sequences that are critical for gene regulation mediated by cell surface receptors."

The surgical correction of postburn nose and lips deformities still remains a difficult task domain to be done by plastic surgery. Consequently, the performance of autogenous cartilage graft and ear cartilage graft to maintain a better philtral form were found to raise the problem of a defect in the unnatural form due to consecutive tension in the region. Recently, focus had been placed on composite graft, including auricular cartilage, to obtain a unique dimple in the philtrum, and concurrently with this, part of its natural form has been acknowledged. However, composite graft on scar beds with poor circulation on the recipient site dose not represent safe survival, has increased risk allotment, which laeds to difficult application. From Jan. 1992 to Dec. 1998, the authors have experienced auricular composite graft in 15 patients who had a defect on the philtrum due to postburn scar contractures. As types of this operation, in method I, the subcutaneous pocket is made at the midline of the upper lip. The next step is cartilage insertion into subcutaneous tissue. The cartilage graft is fixed to be overlying skin by the bolus sutures. In Method II, the recipient site is excavated by some excision of the soft tissue in the central upper lip after scar tissue excision. The obtained auricular skin composite graft is placed and fixed to the philtral area. In Method III the auricular skin composite graft is harvested, and 2 or more 2mm-sized multiple holes are made along the midline of cartilage. Then composite graft is fixed to the defects of philtrum. The elongated portion of the distal tip of cartilage is embedded into the vermilion tubercle for sprouting and fullness. The most effective method was Method III, which enhanced the survival of auricular cartilage graft and its overlying skin, by trimming the margin of grafts, and enhancement of the connecting vessels through fenestrated holes of cartilage between the recipient site and composite graft. The authors hereby report the results of the present study along with study findings based on literature surveys.

OBJECTIVES: To evaluate the effectiveness and the value of Laparoscopic Assisted Vaginal Hysterectomy, and to evaluate the possibility whether to replace abdominal hysterectomy to LAVH. METHOD: A retrospective study of the surgical procedure was performed by one team with one experienced laparoscopist. The operations were carried out in a private hospital, where operative laparoscopic set was available. All 500 patients underwent LAVH from March 1998 to March 1999 at the department of Obstetrics and Gynecology, Eun hospital. Patients were required hysterectomy for uterine fibroid, chronic pelvic pain and carcinoma in situ of cervix,. etc. RESULTS: The average operating time was 56.4+/-11.8 minutes, and the mean estimated postoperative hemoglobin loss was 0.62+/-1.0 g/dL. The mean uterine weight was 223.9+/-129.7 gram (range from 60gram to 800gram). The most common pathologic finding was adenomyosis(59.6%),and the second most pathologic findig was uterine fibroid(47%). No serious complications occured, but 3 vault hematoma cases occured. The combined procedures were salpingoophorectomy, adhesiolysis, and anterior or posterior colporrhaphy, etc. CONCLUSIONS: LAVH that has been possible to replace abdominal hysterectomy, may be valuable for gynecologic uterine diseases, but the experience is important for laparoscopic surgery. The learning curve influences the results of surgery and incidence of complications. Therefore the procedure may only be carried out by experienced laparoscopists, then the maximum value and advantages of laparoscopic surgery can be obtained. Our experience indicates that LAVH is to reduce almost all incidence of abdominal hysterectomy(0.4%)

Though proper management of hand burns in children is provided, hypertrophic scars frequently cause various hand deformities or functional disturbances in growing hands. When correction principles have not been observed for the long term, contraction of the skin, tendon and joints has a serious influence on hand deformities and bone change occur in growing children and second, to determine when is the proper operative time to minimize hand deformities and recurrences. We reviewed 107 hands in 103 admitted pediatric patients who had postburn hands deformities by scar contracture. The analysis of severity of hand deformities was evaluated by assessment of our hospital scale. According to these data, we performed the operations and compared the final results. The results were as follows: The types of burn hand deformities among 107 involved hands of 103 patients included flexion contracture (39.3%), syndactyly (29.9%), extension contracture (10.3%), Boutonniere deformity (9.3%), claw hand deformity (5.6%), severe hypertrophic scar (3.7%), swan neck deformity (0.9%), and loss of digit (1.9%) etc. On 98 preoperative x-ray examinations, bone changes were common, including angular deformity (19.4%), epiphyseal plate loss(18.4%), osteoporosis (17.3%), bony erosion (17.3%), joint change (15.3%), and ankylosis (9.2%). Thus, early correction of postburn hand deformities is imperative in pediatric patients, even though there is a greater chance of secondary operation due to immature scars. All patients were operated on by our proposed protocol and postoperative results showed greatly improved finger joint motion than before. We concluded that early correction of Grade III to V postburn hand deformities is mandatory in rapidly growing pediatric patients.

Pediatric patients often could not be cooperated with physician during various procedures. So, many agents such as inbalation anesthetics and intravenous anesthetics have been used to decrease pain, anxiety and awareness during regional anesthesia in children. The purpose of this study was to compare propofol with midazolam and inhalation anesthetics for emergence time from sedation in caudal anesthesia of children. Forty five patients were randomly divided three groups. In propofol group(Group P, n=15), induction dose of 1.0 mg/kg propofol(Diprivan) was received followed by continuous infusion of 3~5 mg/kg/hr. In midazolam group(Group M, n=15), induction dose of 0.15 mg/kg midazolam(Dormicum) was received followed by continuous infusion of 0.06~0.08 mg/kg/hr. In inhalation anesthetic group(Group E, n=15), O2-NO2-Enflurane(3L/min, 3L/min, 0.6~1.0 vo1% respectively) inhalated through face mask by non-rebreathing system for sedation. The blood pressure, heart rate, arterial oxygen saturation during anesthesia and emergence time, complications were measured. The results were as follows: 1) The blood pressure was significantly decreased in group M and E. Heart rate was also significantly increased in group M and E. 2) The arterial oxygen saturation was not significantly changed in each three groups. 3) In the group P and E, emergence time was shorter than in the group M. From the above results, we conclude that propofol is more excellent intravenous anesthetics than midazolam in respect to emergence time and hemodynamic changes in pediatric caudal anesthesia.
