The blepharoptosis is the disease which is caused by the congenital or acquired weakness of the levator palpebrae superioris. From September 1984 to December 1992, authors had treated 19 blepharoptosis patients(22 cases of operation), and the operative procedures were chosen according to the patient's levator function : levator resection in cases with levator function above 4mm(6 cases), frontalis transfer in cases with levator function below 2mm(5cases), levator resection(7cases) or frontalis transfer(4 cases) in cases with levator function between 2-4mm. And the operative results were evaluated with the average follow up period of 34.5 months. The results were summarized as follows. 1. 15patients were congenital and 4 patients were acquired type of blepharoptosis and sex ratio was 11:4(male:female) in 15 congenital blepharoptosis patients. 2. We performed 13 cases of levator resection and 9 cases of frontalis transfer. 3. In cases of moderate blepharoptosis, whose levator function is 4-8mm or 2-4mm, results of levator resection and the frontalis transfer are both good. 4. In cases of severe blepharoptosis, whose levator function is 2-4mm, result of levator resection is relatively fair, the frontalis transfer is good. 5. Results of frontalis transfer in acquired type showed excellent regardless of levator function. 6. The incidence of undercorrection after levator resection in congenital blepharoptosis was 72.7%, and the frontalis transfer showed frequent severe complication such as persistent lagophthalmos, exposure keratitis, hollowness of temporal area, headache, overcorrection & undercorrection.

The auricle is frequently exposed to trauma due to its protruding anatomical position and it is sometimes severed completely. Many kinds of techniques such as composite graft or cartilage preservation methods for the reattachment or reconstruction of and amputated ear have been tried. But their indications are limited and results are not satisfactory. For the complete survival of ear cartilage and skin of the amputated part, microvascular replantation is known as the best procedure. But cases of successful replantations have been rare until now, because of technical difficulties due to the small size of auricular vessels and uncertain vascular anatomy. In 1980, Pennington et al. reported the first successful microvasclar replantation of a totally avulsed ear using vein graft. After that about 10 cases of world wide successful micro replantation of servered ears were reported. Here, we report a case of a successful replantation of a completely amputated lower half of auricle including the ear lobule due to a human bite. Replantation was done by direct anastomosis of transected peripheral branches of the posterior auricular artery and vein without vein graft. We again emphasize that, in spite of the technical difficulties and long operative time, successful replantation of an amputated ear with microvascular surgery is superior to any other methods of reattachment or reconstruction.

Apoptotic cell death of human leukaemia U937 cells by ubiquinone-9 purified from Pleurotus eryngii

Bae, Jeen-Soo,Park, Jin Wook,Park, So Hyun,Park, Jung Bin,Rho, Yoon-Hwa,Ryu, Young Bae,Lee, Kun-Sik,Park, Ki-Hun,Bae, Young-Seuk Taylor Francis 2009 NATURAL PRODUCT RESEARCH Vol.23 No.12

<P> A chloroform extract of the edible mushroom Pleurotus eryngii showed an inhibitory effect on mammalian DNA topoisomerase I. The topoisomerase I inhibitory compound was purified and identified as ubiquinone-9. Ubiquinone-9 was shown to inhibit the activity of topoisomerase I with IC50 of about 50 µM. Concentration of 110 µM ubiquinone-9 caused 50% growth inhibition of human leukaemia U937 cells, but not that of normal fibroblast NIH3T3 and 3Y1 cells. Ubiquinone-9-induced cell death was characterised with the cleavage of poly (ADP-ribose) polymerase and pro-caspase 3. Furthermore, ubiquinone-9 induced the fragmentation of DNA into an apoptotic DNA ladder, indicating that the inhibitor triggered apoptosis. The induction of apoptosis by ubiquinone-9 was also confirmed using flow cytometry analysis. Taken together, these results suggest that ubiquinone-9 may function by inhibiting oncogenic disease, at least in part, through the inhibition of topoisomerase I activity.</P>

On Ordered Normal Bases and Ordered Compactifications

T₁-공간의 Wallman-type Compactification을 일반화 시킨 순서 Compactification을 취급하고 있다. 순서위상공간(X, τ, ??)의 순서 normal base의 개념을 소개하여 X가 dense embedding되는 compact 순서위상공간(β0(X), τ*, ??)을 만들었고, 순서 normal base βo을 가지고 연속순서를 가진 compact순서위상공간은 (β0(X), τ*, ??)와 iseomorphic임을 밝혔다. The purpose of this paper is to construct an ordered compactification for a topological ordered space with semicontinuous order which generalizes the Wallman-type compatification of a T₁-space. In order to do this, we introduce the concept of an ordered normal base on a topological ordered space, and obtain that for a topological ordered space (X, τ, ??) with semicontinuous order having an ordered normal base β0, there exists a compact topological ordered space (β0(X), τ*, ??) with continuous order, into which X is densely embeded. It is shown that compact topological ordered space (X, τ, ??) with a continuous order having an ordered normal base β0 is iseomorphic with (β0(X), τ*, ??). Hong [1] has introduced the concept of 0-completely regular filters on a completely regular ordered space in order to construct the ordered compactification. Moreover, in [4], Y.S. Park has introduced the concept of bifilter on a topological ordered space and constructed an ordered compactification for a convex ordered topological space with semicontinuous order. In this paper, we introduce the concept of an ordered normal base for a topological ordered space (X, τ, ??) with semicontinuous order and obtain the compact topological ordered space with continuous order which is an ordered compactification for the space (X, τ, ??). For a topological ordered space we refer to [3, 5]. we assume all our topological ordered spaces to be topological ordered space with semicontinuous order. Let β₁ and β₂ be the families of sets. Then we write β₁∪β₂={A|A∈β₁ or A∈β₂} β₁∪β₂={A∩B|A∈β₁ and B∈β₂}.

We define a fuzzy convergence structure which is a correspondence between the prefilters on a given set X and the fuzzy subsets of X. The notion of fuzzy convergence structure is shown to be a generalization of a fuzzy topology.

Background: Positron emission tomography (PET) viability scan is used to determine whether patients with a myocardial scar on single-photon emission computed tomography (SPECT) may need revascularization. However, the clinical utility of revascularization decision-making guided by PET viability imaging has not been proven yet. The purpose of this study was to investigate the impact of PET to determine revascularization on clinical outcomes. Methods: Between September 2012 and May 2021, 53 patients (37 males; mean age = 64 ± 11 years) with a myocardial scar on MIBI SPECT who underwent PET viability test were analyzed in this study. The primary outcome was a temporal change in echocardiographic findings. The secondary outcome was all-cause mortality. Results: Viable myocardium was presented by PET imaging in 29 (54.7%) patients. Revascularization was performed in 26 (49.1%) patients, including 18 (34.0%) with percutaneous coronary intervention (PCI) and 8 (15.1%) with coronary artery bypass grafting. There were significant improvements in echocardiographic findings in the revascularization group and the viable myocardium group. All-cause mortality was significantly lower in the revascularization group than in the medical therapy-alone group (19.2% vs. 44.4%, log-rank P = 0.002) irrespective of viable (21.4% vs. 46.7%, log-rank P = 0.025) or non-viable myocardium (16.7% vs. 41.7%, log-rank P = 0.046). All-cause mortality was significantly lower in the PCI group than in the medical therapy-alone group (11.1% vs. 44.4%, log-rank P < 0.001). Conclusion: Revascularization improved left ventricular systolic function and survival of patients with a myocardial scar on SPECT scans, irrespective of myocardial viability on PET scans.

Clinical, biochemical, and genetic analysis of korean patients with pseudohypoparathyroidism type ia.

Park, Chang-Hun,Park, Hyung-Doo,Lee, Soo-Youn,Kim, Jong-Won,Sohn, Young Bae,Park, Sung Won,Jin, Dong-Kyu Institute for Clinical Science] 2010 Annals of clinical and laboratory science Vol.40 No.3

<P>Pseudohypoparathyroidism (PHP) comprises a heterogeneous group of endocrine disorders with the common feature of resistance to parathormone (PTH), manifested by hypocalcemia, hyperphosphatemia, and elevation of serum PTH despite normal renal function. Herein, the first Korean cases of PHP type Ia are reported. The two patients (6-yr-old female, 7-yr-old male) had typical signs of Albright hereditary osteodystrophy. Genomic DNA was isolated from their peripheral blood leukocytes and the GNAS gene was amplified by PCR and analysed by bidirectional sequencing including all coding exons. Two GNAS mutations were found: c.94A>T and c.344_345insT. Patient 1 had a nonsense mutation of c.94A>T (p. K32X), which has not been previously described; the mother also had c.94A>T, and it therefore was a familial mutation. Patient 2 had a known frame shift mutation for c.344_345insT (p.V117RfsX23). The family members of patient 2 had wild-type sequences. In summary, two Korean patients with PHP-Ia were confirmed by genetic analysis and a novel p.K32X product of the GNAS mutation was identified.</P>
