The cellular alteration following the electric welding light on the rabbit corneal epithelial cells were studied in several conditions wearing various corneal contact lenses on the corneal surface exposed to the light for 5 minutes at 50 cm in each. The enucleated rabbit eyes 5 hours following the application of electric welding light were histopathologically investigated on the cellular structures of the cornea. The result were as follows: 1. The cellular alterations in a group of soft contact lens wearing consisted of multiple vacuole enlargement, separation of interdigitation and Desmosome, intracellular edema, and loss of organelles in superficial and wing cells layer. Loss of microvilli of the corneal superficial cells were observed. 2. Loss of cytoplasmic microorganelles and microvilli intercellular edema in superficial cell layer, and slight vacuoles enlargement in wing cells layer were demonstrated in a group of the direct light exposure group without contact lenses. 3. Loss of microvilli and intercellular edema with separation of interdigitation in superficial cell layer but no specific changes in wing cells layer were exhibited in a group of hard contact lens wearing. 4. The most destructive features of the corneal epithelial cells were observed in a group of soft contact lens wearing, and it was suggested that the doubtful effects of protection on the corneal superficial tissue in the case of soft contact lens wearing were noteworthy.

BACKGROUND: Induction of anesthesia with propofol commonly associated with reduction in systemic arterial pressure, especially in elderly and high risk patients. This reduction is influenced by the dose and rate of propofol injection. The aim of this study was to examine the effect of different injection rate of propofol on vital signs, dose requirement and induction time during induction period. METHODS: Unpremedicated one hundred and twenty ASA physical status I and II patients aged 20~60 years scheduled for elective surgery were randomly allocated into one of four (150, 300, 600, 1200 ml/hr) groups according to speed of injection of propofol during induction period. Loss of verbal contact was taken as the end-point of induction. Vital signs, SpO2, dose requirement of propofol and induction time were checked. RESULTS: As the injection rate of propofol became slower, there were significant reduction in induction dose and increase in induction time (p<0.05). For example, induction dose and time were 1.82 mg/kg, 223 +/- 58 sec in 150 ml/hr group and 3.14 mg/kg, 50 +/- 11 sec in 1200 ml/hr group, respectively. Also, decrease in systolic and diastolic pressure were less marked at lower injection rates. CONCLUSIONS: Slower injection of propofol produces less vital sign changes and dose requirement for the induction of anesthesia.

Prenatal chromosome analysis of amniotic cells at 18 weeks of gestation showed a male fetus to carry a large 15p+ derivative chromosome inherited from his mother. Extra genetic material on the short arm of chromosome IS was silver-negative with Ag-NOR (nucleolus organizer regions) stain, but stained darkly with C-banding method like the distal heterochromatic segment of the Y long arm. Fluorescence in situ hybridization (FISH) using two DNA probes (DYZ1 and D15Zl) showed a red fluorescent signal on 15p+ In addition to a green chromosome 15 centromere signal, confirming 15p to be from the distal Yq heterochromatin.

PURPOSE: This study examined the fitness of a path model on the relationship among perceived health status, self-esteem, self-efficacy, and Yangsaeng for elderly women. METHODS: The subjects consisted of 633 aged women. Data were collected through self-report questionnaires. The data were analyzed with the SPSS and AMOS programs. RESULTS: Perceived health status, self-esteem, and self-efficacy showed a direct effect on elderly women's Yangsaeng while perceived health status and self-esteem showed an indirect effect on their Yangsaeng. Perceived health status and self-esteem showed a direct effect on elderly women's self-efficacy. The hypothetical path model of elderly women's Yangsaeng was proven correct. CONCLUSION: These results suggest that elderly women's Yangsaeng can be enhanced by increasing their perceived health status, self-esteem and self-efficacy. Based on the outcomes of this study, it is necessary to design an intervention program that emphasizes the enhancement of perceived health status, self-esteem and self-efficacy in order to improve elderly women's Yangsaeng.

Background: Iris Koreana NAKAI (IKN) is a flowering perennial plant that belongs to the Iridaceae family. In this study, we aimed to demonstrate the effects of IKN on osteoclast differentiation in vitro and in vivo. We also sought to verify the molecular mechanisms underlying its anti-osteoclastogenic effects. Methods: Osteoclasts were formed by culturing mouse bone marrow macrophage (BMM) cells with macrophage colony-stimulating factor and receptor activator of nuclear factor-κB ligand (RANKL). Bone resorption assays were performed on dentin slices. mRNA expression levels were analyzed by quantitative polymerase chain reaction. Western blotting was performed to detect protein expression or activation. Lipopolysaccharide (LPS)-induced osteoclast formation was performed using a mouse calvarial model. Results: In BMM cultures, an ethanol extract of the root part of IKN suppressed RANKL-induced osteoclast formation and bone resorptive activity. In contrast, an ethanol extract of the aerial parts of IKN had a minor effect on RANKL-induced osteoclast formation. Mechanistically, the root part of IKN suppressed RANKL-induced p38 mitogen-activated protein kinase (MAPK) activation, effectively abrogating the induction of c-Fos and nuclear factor of activated T cells 1 (NFATc1) expression. IKN administration decreased LPS-induced osteoclast formation in a calvarial osteolysis model in vivo. Conclusions Our study suggested that the ethanol extract of the root part of IKN suppressed osteoclast differentiation and function partly by downregulating the p38 MAPK/c-Fos/NFATc1 signaling pathways. Thus, the root part

Chordoid meningioma is a recently established meningeal tumor and is characterized by a chordoma like histologic appearance, peritumoral lymphoplasma cell infiltrates causing systemic manifestations similar to Castleman syndrome and having a good prognosis. We experienced a case of chordoid meningioma in a 25 year-old woman. The patient preoperatively manifested iron-resistant hypochromic microcytic anemia, polyclonal gammopathy with beta-gamma bridging and detected a huge mass in the right temporo-parietal convexity of the brain. Microscopically, the mass was composed of nests and cords of cuboid, partly vacuolated cells in a mucoid matrix, simulating chordoma. The tumor was surrounded by masses of lymphoplasma cells around vessels, many of the plasma cells contained Russell bodies. Ultrastructural findings showed intranuclear cytoplasmic invaginations, microvilli protruding from cytoplasmic surfaces and well formed desmosomes. Some portions of tumor cell surface were covered by stretches of basal lamina.

OBJECTIVE: The purpose of this study was to determine the frequency and distribution of cytogenetically abnormal miscarriages in couples with spontaneous abortions (SA) or recurrent miscarriages (RM). METHODS: Karyotyping of specimens from 164 abortuses with SA and 86 abortuses with RM was successfully performed according to the standard cytogenetic methods using G-banding technique. RESULTS: Among the total 164 cases of SA group, 81 (49.4%) were euploid and the rest (83, 50.6%) showed chromosomal abnormalities. In RM(> or =2) and RM(> or =3) group, 31 (36.0%)/27 (34.6%) cases were euploid and 55 (64.0%)/51(65.4%) cases were abnormal, respectively. A statistically significant difference was found in the rate of cytogenetic abnormality between SA and RM groups (P<0.05). In all groups, women with advanced maternal age (> or =35 years) had a higher rate of chromosome anomalies compared with women younger than age 35 (normal:abnormal = 32.4%:67.6% for > or =35 years and 53.8%:46.2% for <35 years in SA; 19.2%:80.8%/21.7%:78.3% for > or =35 years and 43.3%:56.7%/40.0%:60.0% for <35 years in RM(> or =2) and RM(> or =3), respectively; P<0.05). In SA group, an increase of normal karyotypes was noted with increased gestational age (<10 week, 38.0%; 10-15 week, 53.5%; 16-20 week, 65.7%). In RM group, most of cases were in <10 week and the frequency of trisomies with chromosomes 1 to 10 were increased compared with that of SA. CONCLUSION: There was a statistically significant difference in the frequency and distribution of chromosomal abnormalities between SA and RM groups. Our results will provide useful information for diagnosis and genetic counseling of patients with SA or RM.

PURPOSE: This study investigated the need for information and social support in parents of children with epilepsy. METHODS: A total of 119 parents of children with epilepsy were recruited and asked to fill out questionnaires. RESULTS: Of 119 parents, two-third reported that they received full and sufficient information about their child's disease and its management but one-third felt the information was insufficient and incomplete. Most parents (62.2%) felt at loss when their child had a seizure, either at home or at school. They wanted information on the causes of seizures, adequate steps deal with seizure and steps they should take to become adequate and supportive parents for their children. However, most parents were reluctant to disclose the disease or to receive support from outsiders. CONCLUSION: Regardless of the fact that most parents received sufficient information about the management of epilepsy, they felt at a loss when their child had a seizure attack. Therefore nurses should give specific instruction on seizure management and assess the needs of parents on a regular basis.

The authors statistically analysed transferred patients among 110 ocular perforation injury patients who were admitted to the Seoul Paik Hospital between January 1, 1984 and December 31, 1988. Male was 85.9% and third decade was most common decades(30.5%). Left eye was more affected(59.8%) than right eye. The most common cause was traffic accident(37.%) and perforated site was corneo-sclera(43.%). Subconjunctival hemorrhage was the most common accompanied ocular manifestation(47.0%). Most of the perforated eyes were treated with primary closure of the wound. The final visual acuity was better in patients who were treated at only one hospital two or more hospitals before being transferred. With the above results, the final visual acuity may be related with the number of the hospital which the patients were treated before transferred.
