Granuloma pyogenicum is a benign vascular tumor, usually about 0.5 to 2cm in diameter. It occurs as a single lesion with few exceptions and consists of pedunulated nodule with a dull red or slightly purplish color. We observed a 29-year old man who had multiple satellite recurrences in the scapular region which developed after excision of a single lesion of granuloma pyogenicum. Histapathologic findings showed many newly formed capillaries that had prominant endothelial cells and showed varying degrees of dilation without appearance of epiderrnal collarette sign. The lesions were much improved by X-ray irradiation.

In order to evaluate the accurate diagnosis of scabies through exatr.inations of all requred. conditions, the author conducted an observation on 769 cases of scabies at the Department of Dermatology, Kyungpook University Hospital from January, 1962 to Octover, 1973, In 1962 the frequency of the disease appeared to be low but it dramatically rose to 20 or 30 times between 1963 and 1966, again showing an increasing tendency from 1971. The ratio of frequency between male and female was 4.2: 1. Seasonal occurrence of scahics was found to be highest in winter. Infectious rate in the family was 83.3% and incubation period vas estimated from 15 days to 2 months. Acarus scabiei or its ova were found in 46.5% of all cases examined and in patients over 16 years of age. Acarus scabiei or ova were chiefly found in vesicles of the finger web but the ova were also found in the subungual fold of the finger, which is an important site of examination.

A case of sporotrichosis, developed on left upper eyelid in 2 weeks after double eyelid operation, was presented. Eruptions were distributed along the operation site and similar to pyoderma or keloid. Painless subcutaneous nodule appeared near the lateral angle of eye in 8 months after onset. Sporotrichum schenckii was cultivated from the tissue fluid of the lesion. PAS positive spores were found extra-cellularly and in histiocytes and multi-nucleated giant cells.

Trichophyton verrucosum is a worldwide zoophilic dermatophye. The human infection was first reported in t.he South western part of Korea in 1986 and Fas been increasing in Taegu area. Thirty-one strains of T. verrucosum isolated from the patients in Taegu area were investigated for their mycological features. Gross observation on Sabot rauds dextrose agar, microscopic examination by scotch tape method and slide culture or Sabourauds dextrose agar and potato dextrose agar, and hair perforation test were perforn ed at 37C. The averages of the largest dimensions of the colonies were .9mm at 2 weeks and 59mm at 4 weeks. The morphologic features of the colonies were clasified into three types. Eighteen of 31 strains showed flatwhitish, disc-like colonies with suvmerging hyphae, 11 strains had large radiating follows on the center of the colonies, and 2 strains showed colonies having diffuse fine folds on their surfaces with well-defined borders. On microscopic exaniination, many chlamydospores, antlerlive hyphae, oval and clavate microconidia, and rat tail or string bean shaped macroconidia were observed. It seemed that observation on potato dextrose agar during 10 to 14 days af er inoculation was suitable method for microscopic examination of T. verrucosum. All 31 strains showed positive reaction on hair perforation test.

We have used BALB/c mice as an animal model for the study of anaphylactic hypersensitivity to the house dust mite. For the sensitization, BALB/c mice were injected with a single dose of extracts of Oermatophagoides farinae (D. pa) or Dermatophagoides pteronyssinus (D. pt) mixed with adjuvants (aluminum hydroxide and Bordetella pertussis) intraperitonealy. On days of 15, 30, and 60 after the sensitization, the mice received a challenge dose of the same allergen intravenously to induce anaphylactic shock. The hypersensitivity reactions were scored by anaphylactic shock. And various immunological parameters, including cytokines and immunoglobulin isotypes, were studied in relation with the shock. A high level of anaphylactic shock was produced in the mice by both of the allergens, D, fa and D, pt, at 15 and 30 days after sensitization. In vitro Ag specific proliferative reponses of spleen cells from D. pt treated mice (D. pt mice) was six times higher than those from O. fa treated mice (O. fa mice). Regardless the differences in antigens, the production of IFN-r by spleen cells from D. pt mice or O. fa mice was equally high at 15 days after sensitization. However, the ability to produce IFN-r by the spleen cells from D, pt mice was three times higher compared to that from D. fa mice. The production of IL-4 by the spleen cells was enhanced slightly but not significant in both groups. In studies of the allergen-specific immunoglobulin isotypes in the sera of the mice, the level of IgE in both groups was enhanced slightly but not significant. In contrast, the level of IgG subtypes were increased in both groups. When the levels of IgG were compared by subtypes, the level of IgG1 increased significantly on day 15 when the anaphylactic shock score was maximized in both groups. Increase in IgG2a level at the day was not significant, instead, asignificant increase in IgG2 levels was observed on day 60 after sensitization when the anaphylaxis was almost discontinued. Although a higher level of IgG3 was examined on day 15 and 30 in D. pt mice and on day 60 in D, fa mice, anaphylaxis was not appeared to be associated with the levels of IgG3 in this study. The IgG1, rather than IgE, was assumed to the major factor involved in the anaphylactic response observed in this experiment. In conclusion, BALB/c mice would be an animal model for the study of anaphylactic hypersensitivity to D. fa or D, pt., which might be an essential tool for the future development of immuno-therapeutic agents.

Primary hypothyroidism can result in reactive enlargement of the pituitary gland which is indistinguishable from primary pituitary lesions in clinical presentation and on magnetic resonance imaging. A 17-year-old girl came to the hospital due to short stature, general weakness and galac-torrhea. The magnetic resonance imaging (MRI) study showed pitutary enlargement. The hormone study showed hyperprolactinemia, decreased basal growth hormone level and primary hypothyroi-dism. By thyroid replacement therapy only, mass was successfully regressed on follow up MRI after 4 months, and growth acceleration could be achieved.

Background : Recurrent wheezing in infants is manifested in a number of disease spectrums and gastroesophageal reflux ( GER ) has been known to be associated with apnea, recurrent pneumonia, asthma, chronic cough, and wheezing. The prevalence of GER in infants with recurrent wheezing and the relationship between atopy and GER in infantile asthmatics have not yet been established, but it was hypothesized that microaspiration of food allergen could induce food-induced wheezing. Objective : To evaluate the prevalence of GER in infants with recurrent wheezing episodes, and to determine whether the presence of atopy affects the prevalence of GER in infantile asthmatics. Method : Seventy infants with recurrent wheezing episodes were evaluated for GER using 24 hour continuous esophageal pH monitoring. Patients were classified into five groups, : 12 atopic asthmatics : 20 nonatopic asthmatics : 15 infants with recurrent bronchiolitis : 8 infants with recurrent pneumonia : and 15 infants with chronic lung disease ( CLD ) of prematurity. GER was considered to be prevalent when reflux index was higher than 95 percentile of normal values by Vandenplas, 1991. Result : The prevalence of GER in infants with recurrent wheezing was 21.4%. The prevalence of GER in each group was 25% in atopic asthmatics, 20% in nonatopic asthmatics, 6.7% in infants with recurrent bronchiolitis, 12.5% in infants with recurrent pneumonia, and 40% in infants with CLD of prematurity. There were no significant differences in prevalence of GER between atopic asthmatics and nonatopic asthmatics, between asthmatics with atopic dermatitis and those without, and between asthmatics with family history of allergy and those without. CONCLUSION: The prevalence of GER in infants with recurrent wheezing was high, especially in infantile asthmatics and infants with chronic lung disease of prematurity. The presence of atopy may not affect the prevalence of GER in infantile asthmatics.

Higenamine is known to possess stimulatory activity on beta-receptor of the heart. Chronotropic actions of higenamic were studied in spontaneously beating right atrial muscle isolated from rabbits. The frequency of spontaneous beating and the relative threshold voltage of the right atrium were examined. The relative threshold voltage was defined as the minimal voltage of the given impulse above which the right atrium could be paced at the frequency of 20% of higenamine was also observed. Higenamine caused the postive chronotropic effect. This response became prominent as the ca2+ concentration in the bathing solution lowered. When tetrodotoxin was added to the bathing solution, the effect of higenemine altered and became similar to that of epinephrine. Higenamine reduced the relative threshold voltage of the right atrium in the bathing solution with [ca2+] of 0.5mM. Such effect was abolished by tetrodotoxin. The effects of verapamill on the spontaneous rate and the relativel threshold voltage were inhibited by higenemine. The above results suggest that, aithough the main action og higenamine is on the Ca channel, higenamine also have a minor effect of augmenting the Na channel.

A clinical analysis on the 33 cases of the collateral ligament injuries of the knee joint was made. Those cases were classified in three groups depend upon the width of the joint space by means of stress-radiogram as one plue (less than 5 mm), two plus(5~10 mm), and three plus(more than 10 mm). Twenty one cases were three plus group and were treated operatively and remaining had conservative treatment. This injury is more prevalent in male with the peak in male with the peak incidence of 21~30 years old age group. The most common site of injury of medial collateral ligament is the mid-portion of the ligament where cross the joint line by the 42.3% on operated cases. The lateral collateral ligament has no specific location of injury but more even on its whole length of femoral or fibullar attachment and mid-portion of the ligament. Results were evaluated in three groups of excellent, good and poor. Six out of 12 cases of conservative treatment and nine out of 21 cases of operative group were excellent in result without joint instability, pain and muscle weakness on walking and flexion was available more than 120 degress. Four cases of conservative treatment group and ten of operative group were good in result with occasional pain on walking, mild degree of instability and range of joint motion between 100 to 120 degrees. Four cases had poor result with pain on walking, marked joint instability and less than 100 degrees of joint motion. Overall result of more than good were 90.5% in operative group and 83.3% in conservative treatment group.
