Tolerance to contact hypersensitivity was induced by feeding of different DNCB doses in mice. A total of 40 mice were divided into 4 groups(control group, 6 mg feeding group, 10 mg feeding group, 14 mg feeding group) in experiment I, Degree of tolerance to contact hypersensitivity was rneasured by incremert rate of ear swelling after challenge with DNFB. Experiment 2 was performed in the same method of cxperiment: I with addition of 3 mg DNCB feeding group. The increment ratee were significantly decreased in DNCB feeding groups in experirnent 1 and 2(p<0.0l). But there were no differences statisticalIy between increment rates of DNCB feeding groups.

The clinical symptom complex characterized by syncopal attacks and sudden death in patients with electrocardiographic anomalies, especially a prolonged Q-T interval is known as the Romano-Ward syndrome. When a similar symptom complex is accompanied by congenital deafness, it is called Jervell and Lange-Nieisen syndrome. This study was undertaken to investigate the investigate the incidence of the latter syndrome in the Seoul area. A total of 1,013 children with congenital deafness who attend schools for the deaf were studied by analyzing their electrocardiograms. A corrected Q-T interval of> or =0.44 seconds was defined as a prolonged Q-T interval. The overall incidence of long Q-T syndrome observed in the deaf in the Seoul area was 0.49% as compared to 0.25% reported from elsewhere in the world. The mean age of patients with long Q-T syndrome was 11.3+/-5.9 years and the first syncopal attacks was 4.6+/-1.1 per patient. A valsalva maneuver and exercise tests in the test group were associated with significant changes in T wave configuration and prolonged Q-T intervals while similar changes were not observed in the control group. A larger survey is needed to derive more statistically significant conclusions.

Survey of causes of blindness on 23,249 eye patients who visited to department of Ophthalmology, Han Kang Sacret Heart Hospital, College of Medicine, Hallym University from Jan. 1982 to July 1986 were clinically evaluated. Blindness is defined as visual acuity for distance of 0.1(20/200) or less in the better eye with best correction. Standard Classification of Causes of Blindness recommended from the International Association for the Prevention of Blindness is applied. Estimated number of blindness is 882 persons(1057 blind eyes, 3.80%). For the evaluation of the site of blind eye, 175 persons(19.85%) were binocular and 707 persons(80.15%) were monocular, 375 persons(42.50%) were blind in the right and 332 persons(37.65%) in the left. Distribution of blindness causes by age group is; in male-under 10(3.41%), 11~20(6.06%), 21~30(12.78%), 31~40(10.32%), 41~50(8.42%), 51~60(6.72%), 61~70(5.78%), over 71(4.36%), and in female-under 10(1.80%), 11~20(1.90%), 21~30(4.45%), 31~40(2.65%), 41~50(3.88%), 51~60(5.49%), 61~70(10.13%), over 71(11.92%). Proportion of blindness by causes indicates; Injury and poisoning(31.60%), Senile cataract(28.11%), Infectious disease(9.28%), Others(5.78%), Glaucoma(5.50%), Systemic disease(4.78%), etc. Rate of blindness by site and type of affection is shown as; lens disease(cataract, 37.95%), Corneal disease(10.5%), Glaucoma(5.97%), Phthisis bulbi(5.87%), Anophthalmos(4.93%), Retinal detachment(4.17), etc. Evaluation of result and problems for better reliable survey in future are briefly discussion in comment.

There have been many reports regarding complications associated with cardiopulmonary resuscitation(CPR) and it may be true that there are many unrevealed complications. Although it is used to say that 'any CPR is better than no CPR', inadvertent or inadequate CPR may insult in serious organ injury. This report describes a 64-year-old woman who suffered Mallory-Weiss tear resulting from inadvertent cardiopulmonary resuscitation by a bystander who had never been trained. Possible mechanisms of gastric injuries caused by CPR are suggested, and importance of adequate CPR training are emphasized in this report.

Primary role of ultrasound in patients with thyroid nodule is to determine the multiplicity and detect occult carcinoma. We analyzed US findings of 53 thyroid carcinomas with multiple nodular lesions from january 1988 to december 1991. The results were as follows: 1. 109 malignant nodules in 53 cases and 24 benign in 23 were comfirmed. 2. The nature of the masses were solid in 72 malignant nodules (74.2%), and complex in 25 (25.8%) of which 19 were predominantly solid. 3. The echo pattern of the solid and solid predominant masses were hypoechoic in 78 malignant nodules (80.4%), hyperechoic in 10 (10.3%), and isoechoic in 3 (9.3%) 4. Internal punctate calcifications within the masses were observed in 31 malignant nodules (31.9%). 5. Halo sign was present in 16 malignant nodules(16.5%). 6. The preoperative sonographic diagnosis of thyroid carcinoma was made in 39.4% of 53 cases with multiple nodules on US. In conclusion, the number, and halo formation of nodules were insignificant to differentiate the benign nodule from the malignant. The heterogeneous hypoechoic nodules with size greater than 4cm, multiple stippled calcifications, displacement of the trachea or other surrounding structures of combined lymph node enlargements seem to indicate the possibility of malignancy.

We present herein a case of human infestation of canine scabies occuring in a 7l-year-old female patient. Severe pruritic, erythematous papular lesions and excoriation were found over the abdomen, submammary area, and thigh. The itching sensation was aggravated especially at night. Efforts to demonstrate mites from the lesiona of the patient were unsuccessful. Her pet, a small puppy, showed loss of hair and crusted or scaly erythematous patches on the auricles and trunk 1 month prior to her skin lesions. Sarcaptescabiei var. canis were collected from the puppy by brushing the hair snd crusted or scaly patches on its skin. The patient and puppy were treated successfully with application of 25% benzyl benzoate solution.
