BACKGROUND: In order to delineate the involvement of apoptotic death in post-ischemic cerebral infarction, the temporal expressions of some apoptosis-regulating genes (BCL-2, BAX and ICE) were studied in the parietofrontal cortex of a rat following focal cerebral ischemia using a Northern blot analysis and RT-PCR. METHODS: Animals were decapitated at 0.5, 1, 2, 4, 8 and 24 hours following a middle cerebral artery occlusion (MCAO). RESULTS: With the use of Northern blotting, the expression of proto-oncogene BCL-2, the apoptosis-repressor gene, increased up to 4 hours after a MCAO and then recovered to the control level. In a RT-PCR analysis, the expression of BCL-2 increased up to 8 hours after the MCAO and then recovered to the control level at 24 hours. The expression of BAX, the apoptosis-effec-tor gene, was not altered by a MCAO in a Northern blot analysis. The expression of ICE, an cysteine protease gene, markedly decreased at 1 and 2 hours after the MCAO and then recovered to the control level. CONCLUSIONS: These results show that ischemic insults by a MCAO alter the expression of the apoptosis-regulating genes and support the notion that the apoptosis may have occurred in the post-ischemic cerebral infarction.

Lichen nitidus(LN) is an unaommon chronic eruption of numerou tiny, discrete, usually flesh colored, shiny papules most cornmonly located on the penis, arms, for arms, and abdomen. It was described by Pinkus, first in 1901. The distribution of LN is most often locaized, but in some cases it may become generalized. A 10-year-old healthy boy was seen by our department because of many flesh colored, discrete, shiny papules on the whole body. The papules are skin colored, pinhcad sized, round, and flat-topped. The lesions appeared first at the age of 9 on the forehead and then neased in the number and extended downward to the neck, trunk, abdornen and both extremities. This case was successfully treated with topical corticosteroid.

We report a case of focal dermal hypoplasia associated with ichthyosis in an 18-year-old Korean female. The patient showed a yellowish atrophic patch on the left side of her abdomen, abnormal skin pigmentation, nail dystrophy and ichthyosis since birth.We could also find skeletal and dental deformities. The biopsy specimen obtained from the yellowish atrophic patch showed marked attenuation of collagen fibers and ectopic fatty tissue nearly reaching up to the upper dermis.

Variant angina is characterized by episodic angina due to spasm of an epicardial coronary artery at rest and concomitant transient ST elevation on electrocardiogram. While long-term survival of coronary spasm is usually excellent, but serious complications can be developed such as disabling pain, myocardial infarction, ventricular tachyarrhythmias, atrioventricular block and sudden cardiac death. We experienced 40 year-old man with intractable chest pain due to coronary artery spasm, who suffered from ventricular fibrillation and acute anterior myocardial infarction at the first admission. The patient underwent coronary angiogram, which revealed spontaneous focal spasm at the proximal left anterior descending coronary artery (LAD). He was treated by the combination of nitrate and calcium channel blocker. However, he complained of severe chest pain despite intensive medical therapy and visited emergency room 5 times during 8-month follow-up. We performed ergonovine coronary angiogram and intracoronary ultrasound, which revealed focal spasm at same site of proximal LAD with small amount of localized eccentric atheromatous plaque. Thus we placed coronary artery stent (3.0 x 24 mm GFX stent) at proximal LAD and his symptom was resolved after stenting. We performed follow-up coronary angiogram at 9 months after stenting and stent was patent without any stent recoil and in-stent restenosis.

BACKGROUND: Several kinds of stents have shown their safety and efficacy to treat acute or subacute closure after balloon angioplasty as well as to reduce restenosis rate. However, one of the limitations of stents is difficult to deploy especially in tortuos vessels, lesions at a bend, and distal to previously deployed stents. The Micro stent II, which was one of the most recently developed stents, ia a rapid-exchage balloon expandable stainless steel stent with a zigzag design connected with a continuous single weld in each 3mm segments. It scores over excellent trackability and optimum radio-opacity. Therefore, it is easy to operate and feasible in tortuous, distal lesions and variety of lesion lengths. We report our experiences with Micro-II stent implanatation in the first 76 patients at Tonsei cardiovascular center to assess its safety and efficacy in patients with complex coronary anatomy and clinical results in the first months. METHODS: Between January 1996 and July 1996, eighty-six Micro-II stent were implanted in the coronary arteries of 76 patients(male 65.8%, age 59+/-10 year). Forty-five patients had unstable angina, the others had stable angina(17pts), acute myocardial infarction(14pts). RESULTS: 1) Indication of stenting was de novo 51(59.3%), suboptimal result 25(29.1%), restenosis 1(1.2%) and 9(10.4%) of lesions were stented in bail out situation. 2) Single stent were implanted in 76(88.4%)lesions, overlapping stent in 10(11.6%)lesions. Among overlapping stents, the second stent with Micro-II stent and with another kind of stent were 4.6%, 7.0%, respectively. 3) Procedure related complication including a subacute closure was occurred in 1(1.2%) patient who had distal dissection and 45% residual stenosis. In 12(14%) lesions, preistent dissection has been noticed after stent impantation. 4) Angiographic success(defined as a residual stenosis of <30% without major dissection) was achieved in 82 of 86 attempts(95.3%). The procedual success rate(defined as a residual stenosis of <30% without occurrence of major clinical events within 4 weeks after procesure) was 96.1%(73/76 patients). Angiographic success and procedural success rate in calcified lesion were 100% and 100%, respectively. Angiographic success and procedural success rate in more than 45` angulated lesion were 97% and 100%, respectively. 5) The mean minimal luminal diameter of the target lesions was increased from 0.42+/-0.40mm before stent implantation to 2.93+/-0.50mm(p<0.001). The percentage of diameter stenosis was reduced from 86.49+/-13.04% to 1.40+/-7.11%(p<0.001) after stent implantation. CONCLUSION: Coronary stenting with AVE Micro-II stent can be safety performed and is particularly beneficial in tortuous and calcified arteries. There was a high tendency for peristent dissection which need to special consideration to avoid. Follow-up data is needed to assess mid and term patency. Coronary artery disease .
