There are many reports about the deposition of immunoglobulins and complement by direct immunofluorescence(DIF) in the lesion of scabies. The authors investigated the immunoglobulins and C, for the purpose of studying the immunologic reactivity of the host to scabies mites by DIF. The results are summerized as follows: Total number of the cases investigated were 20 (18 males, 2 females), of whom 11 were in their third decade of age. The clinical forms of the tested lesions were papular type (7 cases), nodular type (12 cases), and Norwegian type (1 case). The durations of the patients were mostly within 2 months, but was 9 months in 1 case of nodular type, Deposition of immunoglobulin and C, was demonstrated by DIF in 10 of 12 cases (83. 3%) of nodular type, and 1 of 7 cases (14. 3%) of papular type. The Norwegian type showed negative results. There seemed to be no relation between the duration of scabies and positive rates. Of 20 cases tested, immunoglobulin and C, were deposited in the vascular wall in 11 lesions (55%), and at the dermoepidermal junction in 3 lesions (15%). While in 1 of 7 cases of papular type both IgM and C, were observed, IgM and C, were noted in 7 and 9, respectively, in 12 cases of nodular type.

Sea urchin granuloma is a rare skin disorder, considered to be allergic or foreign body reaction caused by stick of spines of sea urchin. However, detection of the spine in the granuloma is quite difficult. A 27 year-old marine was seen with several asymptomatic hard nodules on the dorsum of hands, fingers, forearrns and knees at the injured site of the spines after a latent period of 6 rnonths. Histolagical examination revealed dermal granulomatous inflamation with hyperkeratotic and acanthotic epidermis. On examination with polarized microscopy, sea urchin spines in the granuloma were seen as bright white fragments in the dark field. Those nodules were regressed with intralesional injection of triamcinoIone.

Isolation of Microsporum canis from home environment was carried out for 30 tinea capitis patients infected by M, canis. M. canis was isolated in 84.2-100% of patients caps, mattresses, clothes and pillows and families' clothes. The greatest mean number of M. canis colonies per petri dish was found in the patients pillows and followed by caps, mattresses, outerwear, and underwear. Mean number of M. canis colonies in the clothes of mothers, grandmothers, brothers, sisters and roommates of patients was smaller than that of the M. canis colonies in the clothes of patients but greater than that isolated from the clothes of other family members. Frequency of isolation and mean number of colonies decreased drarnatically after 2 weeks therapy and rarely isolated after 6 weeks therapy. M. canis was isolated in 100% of the house dust of patients. Isolation index was greater in the house dust of patients with concomittant infection of other family members and with lesions of scaly and inflammatory type. M. canis was isolated from cats and goat of patients by the hair brush technique.

PURPOSE: The purpose of this study was to determine gender differences in effects of self-efficacy, exercise benefits and barriers, and demographic factors on the physical activity. METHODS: Seventy sedentary office workers, 35 male and 35 female, from a major airline company, completed a questionnaire from March 28 to April 5, 2012. Steps and body mass indices were measured using a CW-700/701 (Yamax) pedometer and Inbody 720 (Biospace), respectively. Data were analyzed using t-test, chi2-test, multiple linear regression, and simultaneous quantile regression. RESULTS: For male workers, exercise self-efficacy had a significant effect on physical activity, but only when respondents were at 10%(3,431 steps/day, p=.018) and 25%(4,652 steps/day, p=.044) of the physical activity distribution. For female workers, marital status was significantly related to physical activity, but only when respondents were at 10% (3,537 steps/day, p=.013) and 25%(3,862 steps/day, p=.014) of the physical activity distribution. CONCLUSION: Quantile regression highlights the heterogeneous effect of physical activity determinants among office workers. Therefore intervention strategies for increasing physical activity should be tailed to genders as well as physical activity levels.

Purpose: The purposes of this study were to compare the magnitude and phase between the RR interval and QT interval variability in the frequency domain. METHODS: Twenty four, 12-13 year old healthy males were randomly selected. At resting state and for 5 minutes, ECGs were obtained, and they were digitized to 1000Hz. After measurement of RR interval, QT interval variability was measured using template matching strategy. After normalization of the RR and QT interval time series, power spectral and cross spectral analysis were performed. From each of the time series, low- (0.04-0.15 hertz) and high- (0.15-0.4 hertz) frequency power were measured. From the phase spectrum, the phases and time lags between the two time series at each of the two frequency range were calculated. RESULTS: The average of RR interval and QT interval was 616.0+/-71.0, 364.0+/-47.0 msec, respectively. Their normalized low- and high- frequency power was 4.4+/-7.9 NU(normalized unit), 0.1+/-0.1 NU(p<0.005), and 11.0+/-30.0 NU, 0.3+/-0.3(NU, p<0.005), respectively. The phase differences and resulting time lags between the two interval were -0.5+/-0.4 pi radian(-0.9 seconds) and -0.2+/-0.3 pi radian(-0.4 seconds) in the low- and high-frequency range, respectively. CONCLUSION: During resting state, when compared to RR interval, QT interval oscillates in significantly lower amplitude in both low- and high- frequency ranges. However, the oscillations precede those of the RR interval 0.9 seconds and 0.4 seconds, respectively.

PURPOSE: This study was done to evaluate the effect and retention of CPR training in nursing students. METHODS: The participants were 64 nursing students enrolled in K University in Busan. Data were collected from April 3 to October 20, 2006 using a structured questionnaire. Data were analyzed using the SPSS/PC 12.0 statistical program. RESULTS: The first hypothesis, that knowledge (t=-17.865, p=0.000) and skill (t=-11.216, p= 0.000) scored directly following the teaching program would be higher than before the program, was supported. The second hypothesis, that knowledge (t=-8.325, p=0.171) and skill (t=-9.812, p=0.062) scored directly after the teaching program would be higher than two months later, was rejected. The third hypothesis, that knowledge (t=-9.162, p=0.010) and skill (t=-6.019, p=0.023) scored two months after the program would be higher than four months after the program, was supported. The last hypothesis, that knowledge (t=9.169, p=0.210) and skill (t=-5.012, p=0.319) scored four months after the program would be higher than six months after the program, was rejected. CONCLUSION: Overall retention of CPR training among nursing students, without reinforcement, decreases most significantly between two and four months following initial training. Accordingly CPR training should be repeated with the same clients every four months.

The search for tumor-avid agents for use in nuclear medicine imaging is an ongoing field of importance. The purpose of this study was to determine the affinity for radiolabeled vitamin B12 by a wide histologic variety of tumor types in mice. Seventeen different types of tumor were grown subcutaneously in female Balb/C or Balb nu/nu(nude) mice. When the tumors reached about 1 cm in diameter, mice were injected intraperitoneally with 57Co-vitamin B12. Twenty-foul hours later, the mice were sacrificed. Organs and tissues were removed, weighed, and activity per mg determined by gamma counter. Values represented cpm/mg tissue that was normalized to 20 grams body weight for each mouse. A wide variety of tumor types showed significant uptake and concentration of 57Co-vitamin B12, as evidenced by tumor:tissue activity ratios. For many tissues of great importance in terms of background(bone, muscle, blood), the tumor:tissue activity ratios of uptake were high. These data strongly suggest that further efforts to evaluate the utility of radiolabeled adducts of vitamin B12 for clinical use in oncologic imaging are warranted.

BACKGROUND: Paraquat is a widely used herbicide, known to cause lethal toxicity in humans. Most studies about paraquat have concentrated on systemic toxicity, however several cases of paraquat-induced dermatitis have been reported. OBJECTIVE: The purpose of this study was to confirm the cutaneous toxic effect of paraquat and to select potential antidotes in paraquat-induced dermatitis. METHODS: Keratinocyte toxicity due to paraquat and the toxicity reduction capacity of several drugs were investigated in eitro. Topical effects of these drugs on paraquat-induced dermatitis in guinea pig skin was also investigated. RESULTS: Over 50% of keratinocytes failed to survive at a concentration of 2X10-4M paraquat by a neutral red uptake assay. Skin irritation by paraquat was observed at 2% concentration by non-invasive methods as well as a skin biopsy. Dexamethasone, glutathione and tocopherol showed some capacity to reduce paraquat-induced keratinocyte toxicity in vitro. Only dexamethasone, however, showed a reduction of cutaneous blood flow volume and dermal inflammatory cell infiltration in the guinea pig study. CONCLUSION: This result indicates the possible in eitro protective effect of paraquat toxicity in glutathione and tocopherol. Dexamethasone was capable of reducing paraquat-induced cytotoxicity and dermatitis both in vitro and in vivo.
