Venous hemangioma is a vascular tumor that has been reported by such diverse names as; "cirsoid aneurysm", "arteriovenous hemangioma", "acral arteriovenous tumor" according to the author's opinions of its origin and histopathologic classification. It is benign and rarely biopsied, and it is also rarely reported in dermatology literature. We present two cases of venous hemangioma. The first case was a 64-year-old man who was presented with an elliptical dark-red plaque with overlying several grouped papules on the left periorbital area which had been present for 7 years. The second case was a 56-year-old man who was presented with a single red papule on the right postauricular area which had been present for 4 months. Histopathologically, there were a well-circumscribed proliferation of thick-walled muscle-containing blood vessels in the dermis. Intermingled with the thick-walled blood vessels, there were also thin-walled dilated blood vessels. In both cases, the thick-walled blood vessels resembled arteries, but they lacked elastic fibers on the Verhoeff van Gieson stain.

The relationship between respiratory infections and exacerbations of wheezing in patients with wheezy bronchitis or asthma has been described. Most respiratory infections were viral or Mycoplasma pneumoniae. This study was performed to evaluate the effect of Mycoplasma pneumoniae infection on bronchial reactivity and atopic background. 106 patients with Mycoplasma pneumoniae pneumonia who were admitted to the department of pediatrics, Fatima Hospital, Taegu during the period of two years from January 1989 to December 1990 were involved in this study. The results were as follows 1) Out of 106 cases, 69 were male,37 were female and 34.9% of the cases were between 5~6 years of age. 35 cases(33.0%) had wheezing and the incidence of wheezing were higher in male than in female. 2) The incidence of wheezing was high in the patients with serum IgE level higher than 200IU/ml, patients with past and family history of allergy and the patients fed with formula feeding in infancy. 3) Eosinophils and the associated maxillary sinusitis had no effect on the incidence of wheezing. 4) The recurrence of wheezing was higher in Mycoplasma pneumoniae pneumonia with wheezing(26.8%) than in patients without wheezing(3.8%).

OBJECTIVE: Immunofluorescence microscopy including confocal laser scanning microscopy and electron microscopy were used to study the production of fibronectin, tenascin, and laminin in the cumulus-corona (CC) cells surrounding mature, unfertilized oocytes after ovulation in view of their presumptive importance in the coordination of the processes leading to fertilization and early embryo cleavage, including the final maturation of the ovum, the sperm-egg interaction, and the complex biochemical mechanism between the ovum and the oviduct. METHODS: Mature oocyte-cumulus complex (OCC) was cultured for 24 and 48 hour and fixed in 3.7% formaldehyde. Specimens were incubated with a mixture of primary monoclonal antibodies recognizing different epitopes of fibronectin, tenascin, and laminin, and then with a mixture of secondary antibodies containing FITC, TRITC, and Cy-5 conjugated antibodies. Observation was made by confocal laser scanning microscope equipped with epifluorescece optics. Transmission electron microscopy were used to observe the OCC at 24 and 48 hours after cultrue. RESULTS: The immunocytochemical date demonstrated that CC masses are capable of producing fibronectin and tenascin but their production is heterogeneous in the CC population. Immunoreactivity to fibronectin and tenascin was shown mostly by inner corona cells, and the intensity of immunofluorescence decreased from the central corona cells to the peripheral cumulus cells. Colocalization of fibronectin and tenascin was evident in most CC cells. Moreover, fibronectin and tenascin immunoreactive material was observed in the intracytoplasmic areas, at the plasma membrane level as well as in the extracellular matrix. Whereas, laminin immunofluorescence was found around plasma membrane and extracellular area, but a intracytoplasmic reaction was rarely observed. The distribution of laminin immunofluorescence was similar to that of fibronectin and tenascin, but in some cumulus cells, colocalization between them was not found. Ultrastructurally, cumulus cells projected numerous long, thin microvilli into the intercellular area and some micovilli penetrated into zona pellucida. The inner layer of the cumulus mass was loose arrangement of relatively uniform, small cells with widened intercellular spaces, whereas in the outer layer, cumulus cells are rather larger in size and compact arrangement by narrow, irregular spaces. A small and large linear gap junctions were easily found at cell contacts. The cytoplasm of most cells had abundant organelles typical of steroidogenesis: numerous mitochondrias, a well-developed smooth endoplasmic reticulum, electron dense lipid droplets, and bundles of microtubules and microfilaments. Rudimentary disrupted basal lamina along the cytoplasmic border was rarely seen in a few inner conora cells. CONCLUSION: Even though the functional role of these extracellular matrix proteins remains still unclear, it is reasonable to suggest that they are necessary in various steps of the reproductive process. Cumulus cells appears to be a heterogeneous and dynamic system for suitable microenviroment of fertilization. And functional differences between corona and cumulus cells during the oocyte denudation may be accounted for particular distribution of these adhesive proteins and steroidogenesis-related organelles.

PURPOSE: Magnetization transfer imaging(MTI) is a new imaging contrast technique. Our MT pulse sequence is designed as fixed time interval between echo and MT pulse. This study was peformed to evaluate the influence of variations in TR/TE on MTR in T1 weighted image of normal brain tissue on this kind of MT pulse sequence. MATERIALS AND METHODS: Seven healthy volunteers in twenties of age as the objectives, MRI was taken under various TR/TE(TR/TE ;700/14, 650/14, 750/14, 700/20 and 1500/20 msec). MTR was calculated from signal intensities measured at the same point in both pre and post MT images and statisticslly analyzed. The MR imager used in this study was 1.0T Magnetom 42SP(Siemens, Erlangen, Germany) and the parameters of additional MT pulse sequence were offset 1000Hz and bandwidth 250Hz, and posteriorly located to echo with 7.7 msec fixed interval. Offset of this MT pulse was variable. RESULT: In white matter of brain tissue from a normal person, MTR was 34-39%(average 37%) for TR and TE of 700/14 in T1WI and 33-36%(average 35%) for TR/TE of 650/14, and 34-38%(average 35%) for TR/TE of 750/14 which showed no statistical difference. However, in case of 1500/20 of TR/TE, MTR was 26-28%(average 26%) which is statistically significant. With TR/TE of 700/14 as the standrd value, the MTR of gray and white matter were 37% and 29% respectively, showing a definite difference of statistical means. Signal from CSF in ventricles is rarely influenced by MT pulse. CONCLUSION: Conclusively, a subtle variation in TR/TE in T1WI has little influence on MTR but wide range of variation in TR/TE as in proton density image induces significant difference in MTR on this kind of MT pulse sequence. Therefore, the exchangeable usage of MTR data would be possible in narrow range of TR/TE change but difficult in wide range of variation.

The gene product of bcl-2 (B-cell leukemia/lymphoma-2) was suggested to suppress programmed cell death (apoptosis) of tumor cells and be involved in the development of multiple myeloma. However, the normal plasma cells also express the protein. It is unclear whether the expression of bcl-2 in multiple myeloma is of normal character or of regulatory adaptation in association with neoplastic transformation. p53 was also suggested to be involved in tumor progression since mutations on p53 were found in multiple myeloma. In order to find the relationship between the expression patterns of bcl-2 and p53 in tumor cells of multiple myeloma and non-neoplastic plasma cells, we examined 38 cases of multiple myeloma and 10 cases of nasal polyp immunohistochemically. Furthermore, expression of bcl-2 and p53, mitosis, clinical stage and infiltrative pattern of tumor cells in bone marrow were also evaluated in association with the survival of patients. By immunostaining with anti-bcl-2 and p53 monoclonal antibody, 37 out of 38 cases of multiple myeloma and all of 10 cases of nasal polyp were positive for bcl-2 but only 7 cases of multiple myeloma were positive for p53. Marked dysplasia, low percentage of bcl-2 expression, and increased mitoses were correlated with poor prognosis. Based on these observations, we suggest that bcl-2 and p53 are involved in tumorigenesis of multiple myeloma and the survival of patients would be influenced by dysplastic change, mitosis and degree of bcl-2 expression.

Korean Journal of Anesthesiology 2001;41(3):393-397
Congenital lobar emphysema (CLE) is a rare entity of unknown incidence. The main signs and symptoms are tachypnea, tachycardia, cyanosis, retractions, wheezing, tympanic chest percussion, asymetric breath sounds, or displaced cardiac tones within the first month of life. Occasionally a superimposed pulmonary infection exacerbates the condition, prompting hospital admission and medical treatment of the pneumonia followed by surgical treatment of the CLE. We now report a case of left upper CLE in a 15-day-old infant. Anesthesia was induced with thiopental sodium and maintained with intravenous fentanyl and midazolam. Endotracheal intubation was uneventful. Muscle relaxation was done with rocuronium. Gentle manual ventilation with a Mapleson D circuit was begun and changed to intermittent mandatory ventilation with an infant ventilator. During the left upper lobe resection, we used high frequency oscillation ventilation (HFOV) at FIO2 1.0, 12 Hz frequency, 12 cmH2O amplitude for 25 minutes. The minimal lung movement during HFOV was found to provide excellent operating conditions for the surgeons and adequate oxygenation without cardiovascular compromise. The PaCO2 was increased to 71 mmHg 25 minutes after the start of HFOV, and returned to normal value with intermittent mandatory ventilation. The remainder of the operation and anesthesia were uneventful. The patient was transferred to the neonatal intensive care unit.

Objectives: The prevalence of cumulative trauma disorders of upper extremities mons watch assembly workers in small-scaled industry was studied. Methods: In 83 workers at five watch assembly factories, symptoms and psychosocial questionnaire, ergonomic Interview, physical examination were conducted. Results: Prevalence of self-reported symptoms was 54.2% and neck 34.9%, wrist/hand 31.3%, shoulder 30.1%, elbow/arm 18.0% by anatomical site. Prevalence of cumulative trauma disorders was 45.8%. Most common disease was myofascial pain syndrome (31.3%). The other diseases were De Quervain disease (9.6%), tenosynovitis/tendinitis at wrist/hand (9.6%), bicipital tendinitis(6.0%), fat. epicondylitis(4.8%), meIn. epicondylitis(2.4%), and cervical disc disease(2.4%). As result of ergonomic interview, repetitiveness was 79(98.8%). There were no differences in the prevalence of self-reported symptoms and cumulative trauma disorders for age, sex, marital status, duration of work In the study, The significant factors of cumulative trauma disorders were occupational task and psychosocial stress in the study. The prevalence of cumulative trauma disorders in high strain group was hlgher (68.4%) than other three groups. The prevalence of self-reported symptoms and cumulative trauma disorders in assembly task was higher (70.0%, 64.0%) than other two tasks. Conclusions: Prevalence of self-reported symptoms was 54.2%, prevalence of cumulative trauma disorders was 45.8% in watch assembly workers. In this study, factor related to self-reported symptoms was occupational task and factors relaxed to cumulative trauma disorders were occupational task and psychosocial stress. This results suggest that differences of ergonomics and environment in occupational task cause differences of prevalence of self-reported symptoms and cumulatlve trauma disorders.

The purpose of this study was to investigate the current status of foodservice management in organizations delivering meal boxes for low-income children during summer vacation. A survey was conducted with persons in charge of meal box production and service of these organizations via mail. Out of 114 questionnaires distributed nationwide, 100 were analyzed (87.8% analysis rate). Over half (53%) of the organizations delivered meal boxes consisting of rice and side dishes while the rest delivered side dishes only. About 81% of the organizations received KRW 3,000 per meal from their local governments and the rest received KRW 3,500. Only 28% of organizations had employed a dietitian. Over one-third (38%) of the respondents were unaware of the official nutritional standard of the foodservice program for low-income children during vacation. Most of the organizations (94%) had menu planned in advance. The average percentage of food cost was 84.1%. Over 40% of the organizations did not keep food samples for sanitation test (43%) and did not take any measures for keeping food temperature during delivery (45%). The organizations delivering rice and side dishes were more likely to be located in cities rather than rural areas and received higher reimbursement rate. The organizations receiving reimbursement of KRW 3,500 or hiring a dietitian were more likely to use standardized recipes, keep food samples for sanitation test, or take measures for keeping food temperature during delivery compared to the counterparts. Respondents reported that increasing reimbursement rate was the most necessary for improving the quality of meal box. This study results showed that the meal box delivery service for low-income children was not properly managed during the vacation, with regards to menu planning and food production. It is recommended that reimbursement rate for meal boxes should be adjusted depending on meal box types and local conditions.
