A 20-year-old woman presented with 2-year history of low back pain. She is a basketball player. There was neither major traumatic episode nor history of febrile illness, On plain roentgenograms, sclerosis and slightly decreased height of L5 vertebral body was detected while the intervertebral disc spaces were intact. We found that L5 body was destructed by materials showing high signal intensity on T2 weighted images and connecting the two adjacent disc spaces on MRI. The initial diagonsis included bone tumors. Vertebrectomy was done and the intravertebral material was revealed as degenerated nucleus pulposus.

A 36-year-old woman was presented with extensive anterior wall myocardial infarction. We tried to perform direct coronary angiography for the purpose of primary stenting. However, coronary angiogram revealed normal coronary arteries without intracoronary thrombi. We continued further evaluations to find out the cause of normal coronary myocardial infarction. The findings of severe hypertensive retinopathy and concentric left ventricular hypertrophy suggested that she had secondary hypertension. The detailed history, laboratory and radiological findings revealed the pheochromocytoma. The tumor was successfully removed by operation.

BACKGROUNG AND OBJECTIVES: Diabetes mellitus is a significant risk factor for adverse outcome after PTCA, which is associated with an increased late mortality and target lesion revascularization (TLR) rates. The beneficial role of coronary stenting on the clinical and angiographic outcomes of diabetic patients is not clearly defined. The aim of this study was to evaluate the early and mid-term outcomes in diabetic patients undergoing elective stenting of native coronary lesions compared with those in non-diabetic patients. MATERIALS AND METHODS: Between July 1997 and June 1998, coronary stenting was performed on 46 lesions in 38 diabetic patients and 126 lesions in 117 non-diabetic patients. Follow-up angiography at mean day of 189+/-45 was performed in 58.7% (91 patients) and analysed by quantitative coronary angiography (QCA). RESULTS: There was a higher incidence of multi-vessel disease in diabetic patients than non-diabetic patients but not statistically significant (71.1% vs 51.3%, p=0.106). There were no differences in major procedural complications and in-hospital events (myocardial infarction, angina and death) in diabetics and non-diabetics. During the follow-up, the incidence of target lesion revascularizton (TLR) and cardiac event free survival did not differ between two groups. CONCLUSION: Coronary stenting in diabetics resulted in a low rate of immediate procedural com-plications and early major adverse cardiac event (MACE), similar to non-diabetics. There were no differences in the mid-term clinical and angiographic outcomes in diabetics and non-diabetics.

Many factors including social rejection, family problems, loss of educational opportunity, fear, prejudice and ignorance, compound the inherent paychologicaI stress of leprosy. In ligh.t of these problems this present study was undertaken to evaluate the psychologica.l status of 1cprosy patients. The subjects of the present study were 220 patients staying at home and 304 control people living in similar isolated areas to resettlemert villages. A self reprort symptom inventory,, SCL--90 symptom check list 90) was used and the group", were analysed and compand by many factors. The results of this study are follows. -countinue-

The T cell responses to hepatitis B surface antigen (HBsAg) were analyzed in acute hepatitis patients, chronic active hepatitis (CAH) patients and asymptomatic carriers. Neither proliferative responses nor substantial cytokine production of peripheral blood mononuclear cells (PBMC) in response to HBsAg was detected. For further studies, HBsAg- reactive T cell lines were prepared from PBMC of the hepatitis patients and asymptomatic carriers. No proliferative response of the T cell lines was observed. Interestingly, however, T cell lines obtained from acute hepatitis patients were found to produce IFN-r, but not IL- 4, in response to HBsAg stimulation, whereas T cell lines obtained from CAH patients and carriers were not. Results of this study suggest that HBsAg-reactive T cells producing Thl type cytokines may play an important role in the viral clearance during acute infections, while defects in those T cells may be responsible for the viral persistency.

During the period from May to October 1969, the authors carried out a series of tests with the aim to ascertain the present status of susceptibility of adult cockraoches to various insecticides. The tests on the susceptibility of cockroaches to dieldrin, D.D.V.P., Diazinon; Dibrom, Malathion and lindane were performed with the topical application and the residual film methods under the conditions of 26 degrees C and 80% of relative humidity. The insects tested were collected from Seoul City and were reared at the laboratory. Some of the important results so far obtained can be summarized as follows: The median lethal doses (LD(50)) of the five insecticides against female adult cockroaches were: 0.4 ug/roach or 4.02 ug/body weight (gm) by Dieldrin, 0.29/roach or 2.88 ug/body weight (gm) by D.D.V.P., 0.29 ug/roach or 2.96 ug/body weight (gm) by Diazinon, 0.54 ug/roach or 5.37 ug/body weight (gm) by Dibrom, and 2.96 ug/roach or 29.60 ug/body weight (gm) by Malathion. And those against male adult cockroaches were: 0.18 ug/roach or 3.29 ug/body weight (gm) by Dieldrin, 0.27 ug/roach or 4.89 ug/body weight (gm) by D.D.V.P., 0.16 ug/roach or 2.91 ug/body weight (gm) by Diazinon, 0.49 ug/roach or 8.97 ug/body weight (gm) by Dibrom, and 1.32 ug/roach or 24.19 ug/body weight (gm) by Malathion. The level of susceptibility of adult cockroaches to the insecticides tested was 1.0-1.6 times higher as compared with the results obtained on the Japanese Takashi strain. The median knockdown times (LT(50)) of the female adult cockroaches by insectcides at 1% concentration of 3 mg per square centimetre were 1.82 hours by Malathion, 1.36 hours by Diazinon, 0.56 hours by Lindane, 0.50 hours by Dibrom, and 2.56 hours by D.D.V.P. A marked difference was seen to exist between the males and the females. The female cockroaches were more resistant than the male to Dieldrin, Diazinon and Malathion.

Cavernous angiomas are considered to be congenital in origin. Patients under age of 14 years usually does not require imaging because they are likely to have a benign abducens nerve palsy, unless they develop additional signs or symptoms of neurologic disease during observation. Here we report a case of an isolated abducens nerve palsy caused by overt hemorrhage from de novo formation of cavernous angioma in the pons. Cavernous angiomas of the brain stem should be considered as a possible cause of isolated abducens nerve palsy in young adult and MRI, including gradient-echo sequences should be performed.
