The mutation of p53 tumor suppressor gene is the most common genetic variation of primary malignant tumors. The occurrence, progression and reaction for medical management of cancers can be different according to the characteristics of p53 gene, even if they are same kinds of malignant tumors. In this study, the property of p53 gene in 4 kinds of squamous cell carcinoma cell lines were investigated by using immunocytochemistry, PCR-SSCP, sequencing and Western blot methods. As a result, p53 mutation detected in 3 kinds of squamous cell carcinoma cell lines. Namely, it is found that T in codon 176 changed to A, and G in codon 281 changed to A in KUMA3 cell lines; CC in codon 241 changed to TT in KUMA4 cell lines; G in codon 266 changed to T in KUMA6 cell lines. In single nucleotide polymorphism of codon 72 of p53 gene, the genetic variations are Arg/Pro heterozygote in KUMA3 and KUMA4 cell lines; Arg/Arg homozygote in KUMA5 cell lines; Pro/Pro homozygote in KUMA6 cell lines. These results will provide useful data for p53 gene researches of various squamous cell carcinomas.

Hypertensive encephalopathy is an acute clinical syndrome that shows central nerve dysfunction with sudden and marked elevation in blood pressure. But its pathophysiologic mechanisms, clinical courses and prognosis are still not clear. In order to study clinical manifestations and response to treatment in patients with hypertensive encephalopathy, we reviewed 45 patients with hypertensive encephalopathy who were admitted in Dept. of Internal Medicine, National Medical Center, from January 1975 to December 1984. The following results were obtained: 1) The ratio of male to female was 1.1:1. The peak age of incidence was in the 6th and 7th decade with mean age of 57.5 years. 2) Among 45 patients, only 29 had known history of hypertension and the average duration of hypertension was 8.1+/-3.6 years. 3) The most common sympotm was severe headache (68.9%). And altered consciousness, nausea and/or vomiting, focal neurologic signs and visual disturbance were also common symptoms in decreasing order of frequency. 4) Funduscopic examination showed hypertensive retinopathy in 20 of 24 (91.7%) patients and lumbar puncture revealed increased CSF pressure in 12 of 20 (60%) patients. 5) In most patients, the mean interval to symptomatic improvement was 2.1 days after administration of anti hypertensive agents, but in 6 patients with initial mean arterial blood pressure above 170mmHg, 4 patients showed delayed response and 2 patients were expired.

This study was conducted to evaluate the effect of a teaching program on patients with myocardial infarction. Forty-five patients were randomly selected 22 were assigned to a teaching group and 23 to a control group. An individualized teaching program was delivered to the teaching group during the hospitalization period. It covered aspects such as: the characteristics of heart disease, the anatomy and physiology of the heart, risk factors of atherosclerosis, medication and diet and exercise therapy. When these subjects were discharged to their homes, they received regular supportive care via telephone or mail for 12 weeks. Atherosclerotic risk factors, including, smoking, exercise, blood lipid profile and BMI were measured before and after the teaching program. Post-testing revealed that the numbers of those who exercised and the number of non-smokers were significantly higher in the teaching group than in the control group. Increased HDL cholesterol (High-Density Lipoprotein cholesterol) was significantly greater in the teaching group than in the control group. The above findings suggest that this individualized teaching program might be helpful at reducing the risk factors of atherosclerosis in myocardial infarction patients.

We report our experience of endoluminal expandable stent placement for the treatment of post- transplant renal artery stenosis. Fourty years old male patient, underwent living donor renal allograft 16 months ago, was admitted due to uncontrollable hypertension and gradual graft dysfunction. On the past history, he had had acute rejection at post-transplant day 4 and it had been treated successfully with steroid pulse therapy. After then, he have been relatively doing well and the graft function has shown normal with serum creatinine of 1.1 mg/dl. His blood pressure has been marked 140/90 mmHg, which has been well controlled with amlodipine (calcium channel blocker) and atenolol (beta blocker). On the physical examination, there was no briut on the iliac fossa and blood pressure was 190/110 mmHg. Serum creatinine was 2.0 mg/dl and blood renin level showed 15.61 ng/ml in supine postion, 11.51 ng/ml in erect postion, which were about 10 times above the normal range, respectively. With the impression of post-transplant renal artery stenosis, angiography was performed. The angiogram showed nearly complete transplant renal artery stenosis(about 90% of the lumen) at the anastomotic site. Expandable metal stent was indwelled successfully into the endolumen of transplant renal artery. After this precedure, the blood pressure of this patient was down to 130/80 mmHg and serum creatinine was stabilized to 1.1 mg/dl. Percutaneous endoluminal stent procedures for resistant transplant renal artery stenosis is promising. Longer follow-up periods are necessary for true evaluation of this procedure.

A case of osteoid osteoma of the third thoracic vertebra was presented because of its rarity in number in Korea. The patient was 27 years old male who had complained of severe attack-like referred pain in the right chest whenever he moved this neck. We could treat the patient successfully by surgical removal of it, which also showed the typical radiological and pathological findings of osteoid osteoma.

The authors describe a case of tuberculous abscess of the cerebellum that originating probably from pulmonary lesion. The development of such a lesion indicates a persistence of infection and an immunological breakdown which may party have been due to unsatisfactory chemotherapy and protein malnutrition. Tuberculous brain abscess, an encapsulated collection of pus containing viable tubercle bacilli, is quite rare and it is different from tuberculoma in several points. Only five cases of tuberculous abscess have been fully documented and bacteriologically confirmed. The clinical, laboratory, and histopathological findings of those reported cases and the author's have been discussed.

A microemulsion cyclosporine(Me-CsA) was developed and became available with more predictable whole blood CsA concentration and minimal inter- and intra-personal variability in daily dosage of CsA. We prospectively performed this study to assess 1) the ability of Me-CsA maintaining the adequate predefined therapeutic level and 2)long-term safety and tolerability of Me-CsA in kidney transplant recipients. A total of 123 renal transplant patients were enrolled on the Me-CsA group, who have been on Me-CsA as an initial main immunosuppressant since their transplantation. This group of patients were compared to 200 renal transplant patients on conventional cyclosporine(Con-CsA) as a historical control group(Con-CsA group). There were no differences in the methods of operation, induction immunosuppression, the strategies of maintenance immunosuppression and anti-rejection therapy between these two groups. The clinical status and laboratory values were monitored at 1,3,6,9, and 12 months after the kidney transplantation. There were no statistical differences in acute rejection episodes, serum creatinine level, and graft failure and survival rate between Con-CsA and Me-CsA groups. In this study, we could demonstrate the significant fluctuation of the mean values of daily dosage and whole blood trough level and their standard deviations of cyclosporine in Con-CsA group compare to those of Me-CsA group. We also could demonstrate early stabilization of CsA blood trough level in patients using Me-CsA. These results mean that Me-CsA has less interpersonal variations than Con-CsA. In conclusion, Me-CsA has more predictable pharmacodynamic characteristics than Con-CsA and comparable tolerability and safety to Con-CsA with no additional side effects.
