This study was carried out not only to determine blood alcohol levels by time but also to examine the changes of working ability and reaction speed after ingestion of alcohol. Fifteen healthy students aged from 21 to 27 volunteered as subjects for this study. Liguor (So)oo) in concentration of 25% ethyl alcohol was administrated with the amount of lml of ethyl alcohol per kg of body weight to the subjects. The concentration of alcohol in the blood were determined by the "Alcohol Sensor 100" at 5, 30, 60 and 90 minutes after the administration of alcohol. Also, the choice reactiontest, the eye-hand coordination test and kraepelin test were examined at the same time after checking of alcohol concentration in the blood. The results of this study can be summarized as follows. 1. Mean blood alcohol level changes resulting from administration of lml of ethyl alcohol per kg of body weight were 0.16%(160+/-57mg/100ml, 0.10%(100+/-42mg/100m1), 0.08%(80+/-36mg/100ml) and 0.03% (30+/-24mg/100%1) at the 3, 30, 60 and 90 minutes after the administration respectively. The peak in the concentration of blood alcohol was 5 miniutes after the ingestion according to alcohol examination by the respiration. 2. As for choice reaction test, reaction times became prolonged as blood alcohol levels increased. The reaction time showed a significant changes when the blood alcohol concentration reached 0.08% or more after alcohol ingestion. 3. In eye and hand coordination test, the accuracy of the performance became decreased as blood alcohol levels increased. The difference of accuracy of the test was significantly shown when alcohol levels in the blood reached 0.08% or more after alcohol intake. 4. As for kraepelin test, the abilities of calculation also became lowered as blood alcohol levels increased. The abilities of calculation differed signigicantly from control group when aichool levels of 0.08% and more.

PURPOSE: Epilepsy is one of the most important morbidities in childhood, but its underlying causes can not be found even though extensive studies have been done. Advances in diagnostic modalities, including neuroimaging such as MRI reveal the apparent underlying causes of epilepsies. Therefore, we evaluated specific causes of symptomatic epilepsy and compared clinical features with idiopathic epilepsy. METHODS: Three hundred nine epileptic children visited the Pediatric Department of Pusan National University Hospital from January, 1991 to June, 1998. Of these, 79 patients were determined as symptomatic epilepsy and the analysis of various clinical features was undertaken retrospectively, according to the presence or absence of underlying causes. RESULTS: Two hundred and thirty two patients(75.1%) were idiopathic and 79 patients(24.9%) were symptomatic, the ratios of male to female and the ages at the onset of first seizure were 1.28 : 1, 1.48 1 and 3.24+/-5.65, 2.40+/-2.86 years(p>0.05, p<0.05), respectively. Causes of symptomatic epilepsy in order of frequency were birth asphyxia(29.9%), CNS malformation(27.3%), CNS infection(22.1%) and others(20.7%). The ratios of male to female and onset age of birth asphyxia, CNS malformation, CNS infection were 2.83 : 1, 1.91+/-2.64, 0.75:1, 2.35+/-2.92 and 1.43 : 1, 2.74+/-2.56, respectively. Seizure types in symptomatic group were classified as partial seizure in 22.1%, generalized seizure in 71.4% and unclassified in 6.5%, compared with those of idiopathic group classified as 46.6%, 51.7%, 1.7%, respectively. Intervals between medication start and seizure control in idiopathic and symptomatic groups were 146.5+/-148.7 days and 246.1+/-247.6 days, repectively(p<0.05). According to their etiology of birth asphyxia, CNS malformation and CNS infection were 364.5+/-315.0 days, 175.4+/-181.6 days, 199.9+/-215.3 days, respectively(p<0.05). CONCLUSION: CNS malformation, birth asphyxia, CNS infection were main causes of symptomatic epilepsy in childhood. In symptomatic epilepsy, generalized seizures was more common and occurred at a younger age. It takes more time to control seizure of symptomatic epilepsy.

BACKGROUND: Most studies of Mycoplasma pneumonia involve a group of admitted patients in hospital, usually with major medical illness. So we investigated the epidemiologic and radiologic features during the course of outbreak of pneumonia in Chunnam coastal area. METHODS: We retrospectively studied the epidemiologic and clinical feature of 105 patients with serologically proven Mycoplasma pneumonia treated at Kwang-Yang Hospital during a epidemic period of Jun. 1993 to Dec. 1993. All cases of pneumonia developed in this period were also reviewed and compared with serologically proven group. RESULTS: 1) There were 63 males and 42 females. 2) More than half(57%) of cases belonged to 5-9 years of age group, and mean age was 6.5 years old. Mean age was steadily decreased as prevalence of Mycoplasma pneumonia had been subsided. 3) A major determinant of the outbreak seemed to .to the population density rather than the population size. 4) The common radiologic features were interstitial in type, and 67 cases was restricted to one lobe. Lobar types are more common in late childhood, and interstitial or diffuse types in early childhood. CONCLUSION: These epidemiologic and radiographic characteristics would contribute to the diagnosis of Mycoplasma pneumonia.

Apocrine hidrocystoma is an uncommon benign tumor derived from the secretory segment of apocrine sweat glands and another name for it is apocrine cystadenoma. A 48-year-old female patient had a solitary, translucent red-brownish cystic nodule, 10 × 6 × 7mm in size, on the periorbital area of her left eye. The lesion had enlarged very slowly for 25 years. We excised the lesion and identified it as apocrine hidrocystoma. This is a case of apocrine hidrocystoma with typical clinical and histopathological findings.

Artichia with papular lesions is a rare congenit,al disease characteriezed by the association of alopecia and papular lesions. We report a case of atrichia with papular lesions in 12-year-old. Alopecia of the scalp and eye brows were present at birth. Nurnerous papular lesions are presentation the trunk, buttock and inguinal area. The histopathologic iinding of a papular lesion showed ker till-filled cyst, and eruptive vellous hair cyst. The patient showed reticulat.ed hyperpigmentation on the hands and feet in addition to the characteristic feature of atriclia with papular lesions.

Plant dermatitis can be classified as primary irritant dermatitis, allergic contact dermatitis, phytophotodermatitis and pseudophytophotodermatitis. Among these, allergic contact dermatitis is seen most freguently. It is generally known that dermatitis causing plants have various characteristics depending on the habitat af different plants. Until now we have had great difficulty in finding the causative factors in plant dermatitis in Korea. This is due to the fact that we do not have anr comprehensive reports regarding domestic or imported timbers concerned in contact dermatiti. The purpose of this thesis is to gather the basic materials necessary to discover the cauae of plant contact dermatitis. All kinds of trees, flowers, and grasses in Korea and imported timbers concerned with contact dermatitis were considered in this study. We strove to ascertain whether the species in our country are the same as found in foreign countries or other different speceies are in our country under the sarne genus found in foreign countries. The basis for our study is several Korean plant books as well as interviews with several native botanists. Vie also discussed major families af plants causing or possible causing plant dermatitis in Korea.
