3.The comparison of survival of the venous flaps according to the location of pedicle and the treatment of superoxide dismutase in the rabbit auricle.
Journal of the Korean Society of Plastic and Reconstructive Surgeons 1998;25(4):538-546
It has been generally believed that the continuous flow of blood characterised by arterial inflow and venous outflow is essential for the survival of flaps. Since Baek et al.(1985) demonstrated the survival of a flap based on only a single vein without arterial inflow, there have been a lot of reports of successful skin flaps that depend on only venous blood flow. The location of pedicle is one of the important factors on the survival of flaps, but there have not been an effective study on the survival rates of venous island flaps according to their location of pedicles. In this study, we compared the survival rates of proximally based venous island flaps with those of distally based ones and attempted to decrease the difference, if any, in the survival rates between them. Distally or proximally based 4x3 cmvenous island flap, whose pedicle was a marginal branch of central vein, was elevated from the auricular cartilage of New Zealand white rabbit. IN the half of 20 rabbits, superoxide dismutase (SOD, 20,000 U/kg) was injected intravenously 30 minutes and 60 minutes after the flap elevation. On the 7th postoperative day, survival areas of the flaps were measured by image analysis system and the vascular network with the flaps were examined by micro fil cast. 40 flaps were divided as follows: proximally based venous flaps, distally based venous flaps, SOD treated proximally based venous flaps, SOD ttreated distally based venous flaps. The results were as follow: 1. The survival rate(79.39+/-9.24%) of the proximally based venous flaps were significantly higher than those(60.79+/-14.10%) of the distally based ones (p< 0.01). 2. SOD improved survival of the flap significantly (p< 0.05), and there was no statistical difference in the survival rates between proximally based venous flaps and SOD treated distally based venous flaps (p = 0.1785). 3. Revascularization was actively developed in the proximally based venous flaps and those flaps treated with SOD, but was minimal in the distally based venous flaps. These results suggested that the vascular pedicle would rather be located proximally than distally in designing the venous island flaps and that SOD treatment may be effective for the enhancement of survival of venous island flaps, especially in distally based ones.

We presented a case of Reiters syndrome consisting of conjunctivitis, arthritis, and skin lesions, occurring in 20-year-o1d male. He had neither an episode of dysentery nor a history of sexual exposure before onset of syndrome. The skin lesions had begun with erythernatous scaly patches on the inguinal region and scalp, and later followed by generalized pustular, psoriasiform and/or hyperkeratotic crusted lesions on the erythematous base. Yellowish discoloration and onycholysis of nails and shallow ulcer of glans penis were observed. Arthritis of the knee and shoulder joints were developed, accompanied by pain, swelling, limited motion, wasting and weakness of both lower extremities. In laboratory investigation, urinalysis, stool examination for parasites and occult blood, renal function test, blood VDRL, and X-ray of chest, both knee. joints, shoulder joint and thoracolumbar spine were within normal limit or negative except for leukocytosis(24, 500/mm), increased ESR(90 mm/hr) and hypoalbuminemia(2.6 g/dl), and he was associated with HLA-A3, A 9, B5, and Rw 49 Histopathologically skin biopsy specimen showed extensive hyperkeratosis, paralceratosis, elongated rete ridges, spongiform macropustule of Kogoj. He was treated effectively with antibiotics, corticosteroid, and methotrexate for two months without recurrence till now.

We report a 71 years old woman with transient periodic limb movement disorder and myoclonus that
appeared after acute gastrointestinal bleeding. The abnormal movements dissolved as the blood loss
was restored. The woman was later found to have an asymptomatic spine meningioma. Iron defi ciency
due to acute bleeding may be the trigger resulting in the abnormal movements in this patient with
subclinical spinal meningioma

Carcinoma of the uterine cervix is the most common malignant tumor in Korean women. It is well known that carcinogenesis is a multi-step event involoving the inactivation of tumor supressor genes, such as p53 gene and RB gene. The inactivation of the normal functions of the tumor-suppressor proteins pRB and p53 are important steps in human cervical carcinogenesis, either by mutation or from complex formation with the HPV E6 and E7 oncoproteins. The pRB protein regulates early cell cyle progression by controlling transit through the G1 phase of the cell cyle. The p53 tumor suppressor gene product also plays a role in cell cycle control by the transcriptional regulation of cyclin-CDK inhibitor. Cervical carcinoma is an excellent model for studying the stepwise progression of cell transformation because this is reflected morphologically by the increasing dysplasia of the squamous cells before it becomes and invasive squamous cell carcinoma. The aim of this study was to examine the expression of pRB and compared that with overexpression of p53 in a series of cervical lesions including normal tissuess, dysplasias, carcinoma in situ and carcinomas by immunohistochemical staining with monoclonal antibody to elucidate the role of these tumor suppressor genes. The result were as follows: 1. In normal cervical mucosa and CIN I , a few positively stained cells for pRB were seen in basal and parabasal layer. 2. An abnormality of pRB, loss of expression was seen in 23.8% of CIN III and in 10.8% of invasive carcinoma. 3. Overexpression of p53 was demonstrated in 14.3% of CIN III and in 59.5% of invasive carcinoma. 4. The immunoreactivity of p53 was significantly increased (p<0.05) in stage II, III than stage I , whereas downregulation of pRB and tumor stage was not correlated. 5. The immunoreactivity of p53 was significantly increased (p<0.05) in squamous cell carcinoma than in adenocarcinoma, adenosquamous carcinoma and CIN III. These result suggest that an alteration of pRB is more frequently implicated in CIN III than invasive carcinoma, whereas overexpression of p53 may be involevd in late progression of uterine cervical carcinoma.

A 22-year-old male has had multiple, grouped, asymptomatic, yellowish flat papules, nodules, and plaques on the knees, elbows, butteeks, hands, and feet. Yellowish nodules first appeared on the heels after birth, and gradually increased in size and number and spread to the knees, elbows, buttocks, and hands. Physical examination revealed normaI except for the skin lesions. Gross finding of the serum was clear and paper electrophoresis revealed marked increase in betalipo-protein and mild increase in prebetalipoprotein, suggesting type II hyperlipoproteinemia Serum cholesterol was 510 mg%, and serum triglyceride was 190mg%. Histopathology showed many aggregates of foam cells on H-E stain and many lipid droplets in the dermis on oil red O stain.

BACKGROUND: A presumptive diagnosis of cutaneous tuberculosis can be made on the basis of patients' history, clinical and histologic findings. However, isolation of Mycobacerum tuberculosis is required for a definitive diagnosis and confirmation can be difficult with traditional techniques, including the direct visualization in tissue and growth in culture. OBJECTIVE: We used polymerase chain reaction(PCR) for the detection of mycobacterial DNA from routinely prepared formalin-fixed, paraffin-embedded skin specimens to evaluate its usefulness as a diagnostic tool. METHOD: We studied typical cases of localized cutaneous tuberculosis. Ten paraffin-embedded biopsy samples obtained from 2 patients with scrofuloderma, lupus vulgaris and tuberculosis verrucosa cutis were analyzed by PCR, respectively. RESULTS: M. tuerculosis DNA was demonstrated in all 10 specimens. CONCLUSION: This study shows that the PCR will be a useful method for the confirmation of the diagnosis in localized cutaneous tuberculosis and many skin lesions thought to be related to M. tuberculosis infection.
