The authors report a case of ruptured large saccular aneurysm of anterior ethmoidal artery, ethmoidal artery associated with anatomically related arteriovenous malformation(AVM). The patient was a 49-year-male who presented with severe headache followed by deteriorated consciousness. Computerized tomography and Magnetic resonance imaging revealed intracerebral hemorrhage in left the frontal lobe and intraventricular hemorrhage and contrast enhancing ring-like mass in the frontobasal area. The cerbral angiography showed anterior ethmoidal artery aneurysm with abnormal vascularity in arterial phase. The patient was treated successfully by clipping of the aneurysm and removing of AVM, Among the reference, I have reviewed this paper is the first case report on the anterior ethmoidal artery aneurysm associated with AVM.

BACKGROUND: In migraine studies, the cerebrovascular reactivity (CVR) using a transcranial Doppler (TCD) has been investigated to elucidate the nature and role of the vascular response. However, past studies have not comprised the posterior circulation including functionally important brainstem structures. The purpose of this study was to compare the simultaneous CVRs between the middle cerebral artery (MCA) and basilar artery (BA) in migraine patients with and without aura, by means of a power motion mode Doppler (PMD) with an anterior-posterior probes fixating device. METHODS: Thirty-six consecutive patients with migranes [15 migraine patients with aura (MA) and 21 migraine patients without aura (MWA)] were compared with 29 healthy volunteers. CVR [(Vmax-Vbase)x100/Vbase] was evaluated by the re-breathing technique. TCD was performed as two steps. First, the velocities and spectra of the MCAs through both temporal windows were simultaneously monitored. Second, those were simultaneously monitored between MCA and BA. RESULT: There were no significant differences in age, sex, baseline hemodynamic values (blood pressure, heart rate), and those of the baseline mean flow velocity and CVR of TCD between the migraine patients and the controls. However, the CVR of the BA significantly differed between the MA and the MWA (39.4+/-13.7 vs 64.6+/-25.4%; p=0.001), among MA, MWA, and controls (39.4+/-13.7, 64.6+/-25.4, 45.6+/-14.9%; p<0.001). CONCLUSIONS: CVR of BA was entirely different according to migraine subtypes: with or without aura. Our study suggests that MWA and MWOA seem to be distinct disorders in terms of different vascular responses of the BA during the interictal period.

gamma-Glutamyltransferase(GGT: E.C. 2.3.2.2.) is a glycoprotein enzyme which is involved in glutathione metabolism and amino acid transport through the plasma membrane. It is distributed widely in several organs including liver, kidney, pancrease and brain. GGTs derived from the brain of Wister rats and BALB/c mice were biochemically purified to a specific activity of 4246.2, 862.1 units per mg of protein, a purification folds 93.7, 43.8 and the final yield 65.8, 44.0% respectively. Electrophoretic pattern of purified GGTs from rats and mice brain shows very similar protein fraction each other. We have produced six monoclonal antibodies(GGT-Mab 1-6) against 2-acetamidogluorene treated rat liver GGT. Using these GGT-Mab 1-6 we performed immunohistochemistry(IHC) to study the distribution of GGT isozymes in normal tissues of rat brain and in neoplastic tissues of human brain. The results indicated that human brain GGT was localized in pericytes of blood-brain barrier, especially in the blood-rich portion of the brain(e.g. cerebellum of rat, meningioma and craniopharyngioma of human). Therefore these Maps may be used to evaluate the distribution of GGT isozymes in different tissues.

Fourty one cases with coronary occlusive disease were anesthetised for aortocoronary bypass graft from May 1977 to December 1983 st Severance Hospital, Yonsei University Medical Center. The main anesthetic agents were diazepam-morphine-pancuronium-O2-N2O in most cases, and supplemented with halothane, enflurane of methoxyflurane in some cases. Nitroglycerin, nitroprusside, triflupromasine, and dopamine were used for keeping the hemodynamic stability before, during and after anesthesia depending on the needs. Two operative death occured in our early years. The mortality rate was 4.87% and no late deaths. The overall anesthetic management for aortocoronary bypass graft surgery is disscussed.

BACKGROUND: Studies using a transcranial Doppler (TCD) to establish cerebral vasoreactivity (CVR) have mostly focused on the anterior circulation. The purpose of this study is not only to evaluate the feasibility of the power motion mode Doppler (PMD) with a probes fixating device, but also to simultaneously measure the CVR between the middle cerebral artery (MCA) and the basilar artery (BA) during hypercapnea simulated by the rebreathing technique. METHODS: Twenty eight healthy volunteers were enrolled. Baseline hemodynamic values (heart rate, blood pressure) were measured while volunteers sat in a comfortable position for 5 minutes. The TCD was performed in two steps. First, velocities and spectra of the MCAs were simultaneously monitored. Then, the velocities and spectra of the MCA and BA were simultaneously monitored by a headset that included an anterior-posterior probes fixating device. The equation for CVR was ([maximum mean velocity baseline mean velocity] x 100/baseline mean velocity). RESULTS: Baseline mean velocities were revealed as follows: (64.0+/-13.7, 65.0+/-11.9 cm/s in right and left MCA; p>0.05; 67.3+/-12.2, -45.3+/-7.6 cm/s in dominant MCA and BA). CVR did not differ between the dominant MCA and the BA (46.1+/-12.1, 46.0+/-15.1%; p>0.05), nor between the right and left MCAs (46.9+/-15.2, 46.4+/-14.8%; p>0.05). There was a positive linear correlation between the CVR of the dominant MCA and that of the BA (r=0.856; p<0.001). CONCLUSIONS: PMD with a probes fixating device for accurate insonation is a useful tool for evaluating the relative CVR between the MCA and BA. Our study suggests that CVR values of the BA are similar to those of the MCA.

A 40-year-old woman presented with ocular discomfort in both eyes that had persisted for several months. Six months ago, she had undergone a bilateral nasal and temporal conjunctivectomy using a bare scleral technique followed by a postoperative application of 0.02% mitomycin C (MMC) to treat her chronic hyperemic conjunctiva for cosmesis. Slit-lamp examination revealed that the patient had bilateral nasal and temporal scleral thinning, and a calcified plaque on her nasal conjunctiva. There was no episcleral tissue present around the wound area, and it was difficult to detect any normal conjunctival tissue in the adjacent area for covering the lesion. We believe that performing an aggressive conjunctival excision procedure followed with MMC application for cosmetic enhancement may be disastrous in certain cases.

In 1976 Ramanathan et al introduced a unilimb circle circuit connecting the CO2, absorber and dome valve. A coaxial breathing circuit, Mera F Type breathing circuit, is very light in weight, compact and it can be made any length. This circuit can be used as a circle system, rebreathing or non-rebreathing system and it can be applicable to both pediatric and adult anesthesia. This circuit is easily adaptable to humidification and pollution control devices. It is especially suitable for any kind of surgical procedures including head, neck and others requiring any awkward positions. A clinical study of this circuit was done in 30 cases and compaired with 18 cases using the coventional circuit. Fresh gas flow, tidal volume and respiratory rate were 4 L/min(02:2 L/min., N2O:2L/min.),10 ml/kg and 12-14/min respectively. Controlled ventilation using a volume preset ventilator was used in all cases. After induction, radial artery cannulation with a 20 G angiocatheter was done and blood gas analysis was performed at 30, 60 and 90 minutes respectively. The blood gas analysis was found satisfactory in either the conventional or the Mera F circuit system.

Appendiceal bleeding is a kind of lower gastrointestinal bleeding. For treatment, it is essential to identify the location of the lower gastrointestinal tract bleeding. Appendiceal bleeding has some diagnostic difficultie. It is a very rare condition, and colonoscopy shows only the appendiceal orfice. Recently, multidetector computed tomography has increasingly been used in the diagnostic evaluation of most vascular diseases. Herein, we report the case of an appendiceal bleeding diagnosed by using abdominal multidetector computed tomography, and we present a the literature.

The efficacy nd tolerance of topical administration of levocabastine(0.5mg/ml)were evaluated in patients with allergic conjunctivitis. A total of 166 patients who had a typical history of atopy and a positive skin test were recruited in this study. Five clinicl symptoms(itch, tearing, chemosis, lid edema and conjunctival injection) were assessed according to a four point scale before the treatment and at 1 and 2 weeks post-therapy. Total symptom severity score before the therapy, 6.68, was remarkably decreased to 2.86 at 1 week and 2.08 at 2 weeks after the treatment. The investigators rated the treatment as globally good or excellent in 68.1% of patients checked at 1 week and 72.5% at 2 weejs after treatment. And the patients evaluated that the therapy ws good to excellent in 66.9% at 1 week and 73.1% at 2 weeks after treatment. Levocabastine eye drops has a fast onet of action with 55.4% of the patients feeling symptom relief within 15 minutes after the first administration. The adverse effect was experienced in 44 patients. Ocular irritation sign, such as foreign body sensation or soreness, was the most frequently reported complaint. These results suggest that levocabastine eye drops is an effective and safe topical alternative for treatment of allergic conjunctivitis.

PURPOSE: Acute lymphoblastic leukemia (ALL) accounts for approximately 75% of all cases of childhood leukemia. We investigated epidemiology, clinical and laboratory features and treatment outcome of the children with ALL in Korea during recent 5 years. METHODS: One thousand forty nine patients were enrolled between January 1994 and December 1998 from 37 major hospitals in Korea. The data regarding the clinical and laboratory features including age, WBC counts at diagnosis, immunophenotype, morphology, cytogenetics and treatment outcome of patients were analyzed retrospectively by review of patient's medical records. Kaplan-Meier survival curves were constructed. The differences between groups analyzed by log-rank test. RESULTS: There were 597 males and 452 females. The distribution between the age 2 and 5 years is most common in 46.1%. The annual incidence rate per 100,000 population varied from 1.6 to 2.2. The 5 year event free survival (EFS) rates according to good prognostic factors were as follows: 67% bet ween 1-9 year of age at diagnosis, 69% in under 10,000/mm3of initial WBC count, 74% in early pre-B cell CALLA ( ) immunophenotype, 65% in L3 morphology, 68% in no CNS invasion. Most of patients were treated by CCG treatment protocol. The 5 year EFS was 63%. Main complications were sepsis (21.8%) and hemorrhage (12.5%). The relapse rate was 15.6%. The common causes of death were sepsis, DIC, pneumonia, relapse. CONCLUSION: Our results could provide the most recent and important information about acute lymphoblastic leukemia of children in Korea.
