Cord blood-derived CD34(+) cells promotes functional recovery in transient middle cerebral artery occlusion model of rat / 대한산부인과학회지

OBJECTIVE: This study was designated to determine the effect of cord blood cell transplantation in ischemic injury model. METHODS: In this study, we administered human umbilical cord blood (hUCB)-derived CD34(+) cells into the lateral ventricle or directly into the striatum and assessed cell migration in mice with cryoinjury and behavioral recovery in rats with transient middle cerebral artery occlusion (MCAo). CD34(+) cells were isolated by magnetic cell sorting using CD34-microbeads and labeled with CM-Dil. RESULTS: When CD34(+) cells were injected into mice brain with cryoinjury, cells were migrated into a injury site after one week of injection. Similarly, injected CD34(+) cells were migrated into the periphery of infarcted area in rats with transient MCAo. When spontaneous activity was measured using a modified neurological severity score (mNSS), it was found that functional recovery was significantly higher when CD34(+) human umbilical cord blood cell (hUCBC) was transplanted 24 hours after stroke compared with phosphate buffered saline (PBS)-injected or CD34(-) transplanted, stroked animals (P<0.05). Although only small portion of transplanted cells were differentiated into neural lineages, CD34(+) hUCBC transplantation increased Brdu incorporation and recruitment of doublecortin (DCX) (+) cells in ischemic boundary zone. CONCLUSION: These results suggest that hUCBC transplantation may be an effective treatment for brain injuries, such as stroke, or neurodegenerative disorders by promoting endogenous repair process of the brain.

A Case of Angiomyofibroblastoma of the Vulva / 대한산부인과학회잡지

Angiomyofibroblastoma is a recently described mesenchymal tumor characterized by unique morphologic features, a propensity to arise in the vulva, and a non-aggressive beni-gn biologic behavior. It is typically well circumscribed and superficially located tumor and its cellularity is variable with hypercellular and hypocellular areas composed of bland-looking, pump stromal cells showing the immunophenotype of vimentin-/desmin - positive, and muscle specific actin(MSA)-/alpha-smooth muscle actin(ASMA) - negative. Spindle or plasm-acytoid cells are the characteristic cell types of most tumors. It is similar to an aggressive pelvic angiomyxoma in histology. Because of histologic similarity and differences in the clinical course and treatment, distinction from aggressive angiomyxoma was needed. It rep-resents new type in the expanding spectrum of tumors of which myofibroblasts constitute an integral component. We experienced a case of angiomyofibroblastoma of the vulva occuring in a 42 years old woman. The lesion was relatively well encapsulated mass(3 X 1.5 X 0.9 cm in dimension), showing intimate admixture of hypercellular and hypocellular area. The tumor contained prominent, somewhat ectatic vessels surrounded by smooth muscle cells, some of which blend or fan out from the muscular walls of the vessels. The margin was relatively free from tumor cells. At immunohistochemical stain, vimentin and desmin was diffuse and weak positive, smooth muscle actin was very a few and weak positive in tumor cells.

The Genetic and Clinical Studies of Ichthyoses / 대한피부과학회지

This study was attempted mainly to estimate the frequency of ichthyoses and its genetic characteristics among general population in Chonnam Province. One hundredand thirtyone subjects heing comprised of 121 with ichthyosis vulgaris, 6 with X-linked recessive ichthyosis and 4 with lamellar ichthyosis visited the department of Dermatology, Chonnam National University Hospital from 1971 through 1980. All except 7 patients had visited the hospital with chief complaints of a skin problem other than ichthyoses itself. The frequency of ichthyosis vulgaris seems to be somewhere between, 1/300 and 1/400. 86% were found to either be sporadic cases or come from families from which not enough information was obtained to define a mode of inheritance. The fact that 43% of the sibling of affected patients developed ichthyosis vulgaris points out that it is a highly penetrant autosomal dominant, disease. Skipped generation was observed in 2 families, and gonadal mosaicism in 1 family. Atopic diseaaes were found only in 12.0% of cnses of ichthyosis vulgaris. The disease appeared in 81% of cases before 1 year af age. The skin lesions of ichthyoses were developed on the lower limhs, back, upper limbs, abdomen and scalp in the order of frequency.

Socio-Psychological Analysis and Rate of Syphilis Infection in Prostitutes, Surrounding the U. S. Air Force in Kunsan / 대한피부과학회지

Following the Korean War, the presence of foreign troops in Korea and lowered. sexual morality caused an increase in the rate of prostitution and related venereal diseases. Though the health authorities made efforts to handle these problems, they didnt obtain any noticeable results, because they neglected the scientific prevention and treatment based on expert knowledge, and the sociopsychological problem, which was the basic cause of the increment in the rate of prostitution. They only took administrative action against the prostitutes. Therefore, in July, 1976, we went to a town(named Silver Town) located on the outskirts of a U.S. Air Force base, and, examined and guestioned a number of prostitutes. Each of the 288 subjects residing in the town was given a questionaire that dealt with individual living attitudes, family and social background, and sociopsychological aspects of tbeir lifestyle. Questionaires were completed anonymously. Serological tests for syphilis, the UDRL and TPHA, were also administered. The results of our atudy are as follows. 1) Most of the prostitutes had grown up in large families, in which females were predominant. Because of economic difficulties they dropped out of school a.t an early age and became prostitutes. The average age of a prostitute at the time of her first sexual experience was 19. 9 years, the expriences usually taking place with her first boyfriend. Forty six psrcent of tbe subjects had intercourse for the first time between the ages of 15 and 19. Fortynine & two tenths percent of them because prostitutes within one year of their initial sexual act, and all of them at an average interval of 2.5 years following the first sexual experience, the average age being 22. 4 years. 2) The longer the women had worked as prostitutes, the more they felt dissatisfied with their work, and the more they desired to change to an occupation which was healthier and entailed more self-respect. 3) Out of 283 subjects, 39% had a history of venereal disease, predominantly of gonorrhea. Tbe results of the STS administered to all subjects were,; VDRL 7.7% positive and TPHA 6% positive. It was also concluded that the subjects had no educational or working knowledge of venereal diseases.

Report of a Case of Solid Pigmented Basal Cell Carcinoma Resembling Clinical Malignant Melanoma / 대한피부과학회지

A fifty-seven-year-old, faers wife, was affected a skin lesion of dark pigme raised, crusted ulerated, easy to bleed on touching the crust and indurated ur with mood consistancy, and the tumor was located over the inner is of left eye, which was alike to malignant melanoma clinically. The tumor 1-shaped and measure 1.;. m x l. 7cm in diameter, which did not make any itchy sensation. d with small papule about 8 years ago which zdually increased. in siiarate3 with ocsional ble 3ing. Her skin lesion was treateQ with curretation and electrodessication or surgical removement by loca.l practitioner, however, it recured after the each treatments. In this hospital, the peeived the skin biopsy of the tumor and the diagnosis was established as cell car.cinoma histopathologically, and the tumor was removed by ical technique applying transposition skin flap from the infra-orbitale face, and the result was satisfactory without "mcurence until upto bservation (for three years and three months). On the conclusion, ad a case of Solid pigmented basal cell carcin- oma resernbling maligna. with histopathological study and treated with plastic surgical management very satisfying result.
