We studied 105 patients with trasmural myocardial infarction who were admitted to Soonchunhyang university hospital from 1984-1988, and evaluated the clinical and coronary angiographic findings accordin to the age. The following results were obtained: 1) Among 105 patients with myocardial infarction, the prevalent age were sixth and seventh decade(27.6%) and the ration of male to female was 2:1, But the raion of male to female was 5.3:1 under the 50 years of age. 2) In frequency of risk factor of coronarhy heart disease, cigarrette smoking was present in 66.7%, hypertensio in 44.8% and hypercholesterolemia in 28.6%. The mean number of risk factor was 1.3 under the 50 years of age and was 1.7 over the 50 years of age. 3) Anterior myocardial infarction was most common under 50 years of age whereas anterior and inferior myocardial infarction occur similarly over the 50 years of age. 4) By coronary angiography, one vessel disease of stenosis of left anterior descending coronary artery was common findings under 50 years of age, but multivessel disease was common findings over the 50 years of age.

Os Subtibiale, inconstant bone over the tip of the medial malleolus, is the very unusual findings and extreme rarity of the condition. We experienced a case of Os subtibiale in a 24 year old man who complained pain and tenderness an the bilateral medial malleolar region. The patient was treated by excision with satisfactory result.

Cystic parathyroid adenoma is one of the rare causes of hyperparathyroidism, and is usually located in neck and mediastinum. This type of adenoma tends to cause increased serum level of parathyroid hormone and alkaline phosphatase, similar serum calcium level when compared to those of solid adenoma. Thanks to current radioimmunoassay and easy accessibility to serum autoanalyzer, serum calcium level and parathyroid hormone level are more easily measured, which in turn lead to more easier diagnosis of hyperparathyroidism. Also improvement in imaging and nuclear diagnostic method of parathyroid lesion are suggested to enable easy diagnosis of cystic parathyroid adenoma. A 35-year-old male presented with easy fatigability for 12 months. The serum calcium, phosphate, alkaline phosphotase were 11.5mg/dL, 1.4mg/dL, 194IU/L respectively and his parathyroid hormone level in serum was 126.42pg/mL. Neck CT showed enlargement of right lobe of thyroid gland with well defined inhomogenously enhanced density inside the right thyroid gland. The patient was diagnosed of hyperparathyroidim due to parathyroid adenoma and was surgically removed. The surgical biopsy showed cystic parathyroid adenoma. After operation his general condition was improved and serum calcium, phosphate, parathyroid hormone level were normalizd. We report a case of hyperparathyroidism caused by cystic parathyroid adenoma with brief review of literature.

BACKGROUND: We studied clinical and angiographic findings of 16 Korean patients who had isolated laft coronary ostial steonsis and compared them with those of the patients with non-ostial left main stenosis. The aim of this study is to find the characteristics of the patients with isolated left voronary ostial stenosis. METHODS: Medical records and coronary angiograms were reviewed. We divided the patients with left main stenosis into four groups by lesion location and associated lesion. Clinical and angiographic findings of each group were compared. RESULTS: Twenty four patients(0.15%) had left coronary ostial stenosis and among them sixteen patients(0.1) had an isolated lesion. Their mean age was 48 years and 62% were female. Only 6 patients had coronary risk factors. Two patients were diagnosed as having Takayasu's srteritis. At treadmill exercise test, 7 out of 11 patients lhowed positive results at stage I. Eight patients had undergone surgical treatment. Comoared with the patients who had non-ostial left main stenosis, left ostial group showed lower mean age, female preponderance and lower incidence of coronary risk factors. There was no difference in the results of treadmill exercise test and hemodynamic parameters. CONCLUSION: Isolated left coronary ostial stenosis in Korea also predominantly occured in young female patients who had less risk factors as previous reports. But the incidence of this lesion and nonatherosclerotic origin seemed to be higher. And most of the patients with the left coronary ostial stenosis had isolated ostial stenosis.

Mirror movements(MMs) are involuntary movements executed on one side of the body during voluntary movements of the contralateral homologous body parts. Motor evoked potentials(MEP) to focal transcranial magnetic stimulation(TMS) have postulated that abnormal ipsilateral corticospinal tract is active in the patient with congenital MMs. MEP and post-MEP SP following to focal TMS were investigated in a patient with the Klippel-Feil syndrome(KFS) showing MMs and in five normal volunteers. In the patient unilateral transcranial stimulation evoked bilateral motor responses of normal latencies and SP was observed bilaterally, which tended to be shortened in duration. In the condition of KFS, the mechanism of MMs has been attributed to the presence of abnormally activated ipsilateral corticospinal tract, but it does not suffice for explaining the shortened SP. We propose that concurrent activation of both motor cortices be responsible for the mechanism of MMs in this case of KFS, in addition to the abnormality of the corticospinal tracts.

BACKGROUND: Pregabalin is an anticonvulsant and analgesic agent that interacts selectively with the voltage-sensitive-Ca(2+)-channel alpha-2-delta subunit. The aim of this study was to evaluate whether the analgesic action of intrathecal (IT) pregabalin is associated with KATP channels in the rat formalin test. METHODS: IT PE-10 catheters were implanted in male Sprague-Dawley rats (250-300 g) under inhalation anesthesia using enflurane. Nociceptive behavior was defined as the number of hind paw flinches during 60 min after formalin injection. Ten min before formalin injection, IT drug treatments were divided into 3 groups: normal saline (NS) 20 microl (CON group); pregabalin 0.3, 1, 3 and 10 microg in NS 10 microl (PGB group); glibenclamide 100 microg in DMSO 5 microl with pregabalin 0.3, 1, 3 and 10 microg in NS 5 microl (GBC group). All the drugs were flushed with NS 10 microl. Immunohistochemistry for the KATP channel was done with a different set of rats divided into naive, NS and PGB groups. RESULTS: IT pregabalin dose-dependently decreased the flinching number only in phase 2 of formalin test. The log dose response curve of the GBC group shifted to the right with respect to that of the PGB group. Immunohistochemistry for the KATP channel expression on the spinal cord dorsal horn showed no difference among the groups 1 hr after the formalin test. CONCLUSIONS: The antinociceptive effect of pregabalin in the rat formalin test was associated with the activation of the KATP channel. However, pregabalin did not induce KATP channel expression in the spinal cord dorsal horn.

Asthma is a complex and heterogeneous disease, which is comprised of seperate phenotypes sharing common characteristics, such as airway inflammation, bronchial hyperresponsiveness and variable airflow limitation. Traditionally, asthma phenotypes have been described by combinations of clinical characteristics, according to the expert's recommendation, but they are now focusing on the pathobiologic mechanisms often using exploratory statistical methods. Several phenotypes and endotypes have been suggested by biased or unbiased phenotyping approaches. However, more detailed studies are still needed. In the future, more integrated large-scaled consortium of cohorts, including clinical information, genetics, molecular biology, and experiments will promote to understand the pathobiologic mechanisms of asthma phenotypes for the personalized therapy.

OBJECTIVE : To analyze the methylenetetrahydrofolate reductase (MTHFR) mutation in recurrent spontaneous abortion associated with hyperhomocysteinemia. MATERIAL AND METHOD: The blood Sample of habitual aborter with high fasting homocysteine level was tested by PCR-RFLP method. RESULTS: The patient was found to be a homozygosity for MTHFR gene mutation that was confirmed by the finding which is consistent with the mutation at the nucleotide 677 C to T, Corresponding to Ala to Val. CONCLUSIONS: Hyperhomocysteinemia due to MTHFR mutation is a cause of recurrent spontaneous abortion. Therefore, the MTHFR mutation should be examined in the workup of recurrent spontaneous abortion showing hyperhomocysteinemia.
