Left ventricular ejection times were measured from indirect carotid arterial sphygmograms and digital plethysmograms in 118 healthy males and 106 healthy females. The carotid-derived left ventricular ejection time, which was generally accepted as a standard measurement, was shorter than the other in both sexes. However, there was a significant correlation between these two measurements in males and females. This suggests that the left ventficular ejection time obtained from the digital plethysmogram could provide a comparable information to that of the carotidderived one.

Hepatic blood flow was studied by the determination of the fractional clearance of intravenously administered colloid 198Au in 35 cases of normal subjects, 36 cases of liver cirrhosis, 18 cases of primary cancer of the liver, seven cases of liver abscess, five cases of hepatitis and 10 cases of hepato-biliary diseases. There was no appreciable difference in the mean values of the fractional clerance between the normal subjects and biliary tract diseases. On the contrary, it was diminshed in liver cirrrhosis, primary cancer of the liver, hepatitis and liver abscess compared with that in the normal subjects, and the diminution in liver cirrhosis and primary cancer of the liver was significant, and also the fractional clearance in the former was significant, and also the fractional clearance in the former was significantly smaller than that in the latter. However, the individual datum both in the normal control and diseased groups showed a marked overlapping among them except that in the normal subjects and biliary tract diseases the fractional clearance was above 0.10 in almost all cases. In cirrhosis of the liver there was no relationship between the fractional clearance and liver functions.

A 58-year-old male presented with a pruritic, erythematous hread-like eruption on the right chest, which appeared as a small papule since 6 months prior to his visit. Histopathologic examination showed a burrow containing numerous eosinophiles and a few mononuclear cells in the epidermis. There was focal spongiosis unde the burrow. In the dermis, there was a diffuse and occasionally dense perivascular and periadnx 1 inflammatory cell infiltration consisting of eosinophiles and some lymphocytes. Multiple histologic sections were made without success in deizo strating parasitic tissue in the epidermis, however, the clinical and histopathologic features we onsistent with cutaneous larva migrans.

Respiratory effects of acute coronary embolism were studied in mongrel dogs. Coronary embolism was produced by Agress's method and respirtory effects were observed for two hours. In the experimental group, in which coronary embolism was produced, there were relative decreases in respiratory rate and arterial oxygen saturation along with relative increases in tidal volume, minute ventilation, ventilation equivalent and arteriovenous oxygen difference compared to those in the control group. However, differences in these various measurements between tow groups, those in tidal volume and arterial oxygen saturation, have greatly diminished in two hours. These facts suggest that changes in respiratory rate, minute ventilation, ventilation equivalent and arteriovenous oxygen difference in the experimental group are early but short-lasting responses to acute coronary embolism, whereas changes in tidal volume and arterial oxygen saturation occur early and last longer.

BACKGROUND: Canine scabies is caused by an infestation of Sarcoptes scabiei var. canis (S. canis) in dogs and they can be transmitted to humans. Recently pet raising has been increasing in Korea and various parasitic infestations contracted from them have also been increasing including canine scabies. OBJECTIVE: The purpose of this study was to examine the clinical and histopathological features of experimental canine scabies. METHODS: Two dogs experimentally infested were observed for a year. They were examined physically and the numbers of S. cans were counted from scraping samples of the ear, leg and abdomen every 3 to 7 days and skin biopsies were taken. One was given systemic corticosteroids(Dogl) and the other was observed in its natural course(Dog2). RESULTS: Dogl-Clinically severely pruritic, markedly thick hyperkeratotic scales, crust and generalized erythema on the whole body developed with huge numbers(up to 754.9/100mg from scales of the abdomen) of mites, and histopathologically showed features similar to human crusted scabies. Dog2-Clinically showed milder features than Dogl including the number of S. canis(up to 242.6/100mg from scales of the ear), but histopathologically showed similar features with Dogl. Dog2 also showed a prompt response to one topical application of 20% benzyl benzoate solution. CONCLUSIONS: 1) The number of S. canis increased markedly in both normal and corticosteroidtreated dogs, although it was more significantly increased in the corticosteroid-treated one. 2) Histopathology showed features similar to classical scabies in the early stage but features of human crusted scabies in the full-blown stage. 3) Morphologically Sarcoptes canis differs from Sarcoptes scabiei var. hominis.

We have experienced 113 cases of neonatal sepsis comfirmed by clinical manifestations and blood cultures from Jan. 1988 to Dec. 1992 at the Neonatal Intensive Care Unit of Ulsan Dong-Kang Hospital and observed the incidence, predisposing perinatal factors, clinical manifestations, associated illnesses, laboratory findings, isolated microorganisms, antibiotics sensitivity test and mortality rate of neonatal sepsis according to onset of disease. The result were as follows: 1) The incidence of neonatal sepsis was 1.39% and male to female ration was 1.38:1. The incidence and sex difference between early onset and late onset disease were not significant. 2) Neonatal sepsis was more prevalent in premature infants (2.47%) than in fullterm infants (1.28%) and nore prevalent in low birth weight infants(3.01%) than in normal birth weight infants (1.25%). In premature infants, neonatal sepsis was more prevalent in early onset (63.2%) than in late onset diease (36.8%). In low birth weight infants, neonatal sepsis was more prevalent in early onset (64.8%) than in late onset dieases (35.7%P). 3) Predisposing perinatal factors, such as meconium staining, birth asphyxia, difficult delivery, premature rupture of membrane, maternal infection, toxemia and postpartum bleeding were slightly frequent in early onset disease. 4) Among the clinical manifestations, jaundice, respiratory symptoms, pallor, lethargy, poor feeding and hepatosplenonegaly were slightly frequent in early onset disease, but temperature instability and gastrointestinal symptoms were slightly frequent in late onset disease. 5) Among the associated illness, pneumonia, disseminated intravascular coagulopathy, amnionitis, hyaline membrane disease and osteomyelits were more common in early onset disease, but gastroenteritis, urinary tract infection, necrotizing enterocolitis, wound infection and meningitis were mors common in late onset disease. 6) The difference of laboratory findings between early onset and late onset disease was not significant. 7) Causative organisms were gram positive organisms in 87 cases(77.0%), gram negative organisms in 22 cases (18.6%) and mixed infections in 5 cases (4.4%). Among them, coagulase negative staphylococcus was the most common one and staphylococcus aureus was the second. The incidence of infections caused by coagulase negative staphylococcus and staphylococcus aureus, between early onset and late onset disease, was not significantly different. Streptococcal infection was more prevalent in early onset disease, especially all group B streptococcus caused early onset disease. 8) Gram positive organisms ware sensitive to Cephalothin (92.9%), Chloramphenicol (90.0%) and Ceftriaxone (88.9%). Gram negative organisms were sensitive to Amikacin (91.3%) and Colistin (82.6%). The difference of antibiotics sensitivity for organisms causing early onset and late onset diease were not significant. Gram negative organisms causing early onset disease were resistant to gentamicin and terramycin, but those organisms causing late onset disease were more sensitive to gentamicin (88.9%) and tobramycin (77.8%). 9) The mortality rate was 7.96%. It was higher in gram negative infections (23.8%) than in gram positive infections (4.6%). No significant difference of mortality rate between early onset and late onset disease was found.

Hobnail hemangioma(HH) is a benign acquired vascular tumor of endothelial origin which should be differentiated from other malignant vascular neoplasm such as Kaposi's sarcoma or angiosarcoma. We report a case of hobnail hemangioma in a 21-year-old woman who had a dusky-red patch on her left shin. Histologically, ectatic vascular channels with a single layer of plumped endothelial cells were seen and the vascular channels seemed to dissect the collagen bundles. She underwent treatment with surgical excision with primary closure.

BACKGROUND: The purpose of this study was to evaluate the applicability of the Korean version of Fall Efficacy scale(FES) and Activities-specific Balance Confidence Scale(ABC) to Korean older adult through an examination of instrument`s internal consistency and validity METHOD: A sample of 90 Korean older adults who lived in a community completed a survey instrument which included Korean version of FES and ABC. Because of comparable data derived from each scale, fear of falling and quality of life, activity daily living were included. Concurrent validity, criterion validity and correlational validity were tested. Reliability was tested by internal consistency, test-retest method. RESULTS: Cronbach`s alpha was 0.9043 in FES, and 0.99623 in ABC. Test-retest correlations in all scales were higher than 7.0. Statistically significant association was found between fear of falling and both scales. Correlation coefficient between Quality of life(SF-8) and ABC was -0.142(p=0.049). Both FES and ABC are correlated significantly each other. CONCLUSION: The Korean version of FES and ABC appears to be a reliable and valid method for meas- uring fear of falling. These instruments may be useful in assessing the independent contribution of fear of falling. ABC scale may be more useful to detect loss of balance confidence in more highly functioning seniors.
