The effect of 0.25% and 0.5% Timolol on intraocular pressure and concentration in aqueous humor was studied after topical instillation in the white rabbit. The intraocular pressure was measured with pneuma tonometer and the Timolol concentration in aqueous humor was measured with High Preformance Liquid Chromatograph after fine needle aspiration of aqueous humor at various time intervals. The results were as follows; 1. The percentage reduction of intraocular pressure increased with time and reached a peak after 3 hours. 2. The concentration of Timolol in aqueous humor increased with time and reached a peak after 3 hours. 3. There was close correlation between intraocular pressure and Timolol concentration in aqueous humor.

A great number of operative techniques has been described about the correction of the prominent ears. The most primary deformity of the prominent ears comes from an underdeveloped or unfolded antihelix, which results in widening of the conchoscaphal angle and/or flattening of the superior crus, and which, in severe forms, involves antihelical body and inferior crus. Most authors manage the prominent ear deformity by excising, suturing, scoring, or sculpturing the auricular cartilage. We carried out a modified quilting suture technique in order to produce an antihelix. This technique provides several advantages; 1) it prevents the bowstring of the suture material during the formation of the helix; 2) the procedure is easy and time-saving; 3) the reconstructed ear shows reliable results in firmness and stability against external force or trauma; 4) the recurrence rate is not more than that of the conventional methods.

Plasmodium vivax malaria re-emerged in South Korea in 1993, and epidemics continue since then. We examined genetic variation in the region encompassing the apical membrane antigen-1 (PvAMA-1) of the parasites by DNA sequencing of the 22 re-emerging P. vivax isolates. The genotype of the PvAMA-1, which was based on sequence data previously reported for the polymorphic regions, showed that two haplotypes were present at one polymorphic site. Compared with reported data, the two types, SKOR type I and type II, were similar to Chinese CH-10A and CH-05A isolates, respectively. Thus, the present study showed that two genotypes of AMA-1 genes coexist in the re-emerging Korean P. vivax.

BACKGROUND AND OBJECTIVES: The purpose of this study was to evaluate the efficacy of revision cochlear implant (CI) surgery for better speech comprehension targeting patients with low satisfaction after first CI surgery. SUBJECTS AND METHODS: Eight patients who could not upgrade speech processors because of an too early CI model and who wanted to change the whole system were included. After revision CI surgery, we compared speech comprehension before and after revision CI surgery. Categoies of Auditory Performance (CAP) score, vowel and consonant confusion test, Ling 6 sounds, word and sentence identification test were done. RESULTS: The interval between surgeries ranged from eight years to 19 years. Same manufacturer’s latest product was used for revision surgery in six cases of eight cases. Full insertion of electrode was possible in most of cases (seven of eight). CAP score (p-value=0.01), vowel confusion test (p-value=0.041), one syllable word identification test (p-value=0.026), two syllable identification test (p-value=0.028), sentence identification test (pvalue=0.028) had significant improvement. Consonant confusion test (p-value=0.063), Ling 6 sound test (p-value=0.066) had improvement but it is not significant. CONCLUSIONS: Although there are some limitations of our study design, we could identify the effect of revision (upgrade) CI surgery indirectly. So we concluded that if patient complain low functional gain or low satisfaction after first CI surgery, revision (device upgrade) CI surgery is meaningful even if there is no device failure.

Pulsed Doppler echocardiography was performed before and five to fifteen days (mean, 9.3 days) after mitral valve surgery to evaluate the change of pulmonary arterial pressure in 80 patients (29 males and 51 females) with mitral valve disease by preejection period (PEP)/acceleration time (AT) ratio at the right ventricular outflow tract. In 13 patients with pulmonary hypertension (mean pulmonary arterial pressure equal to or greater than 20mmHg), Doppler echocardiography was followed three to twelve months after operation. In 76 patients with a mitral valve prosthesis (15 patients with the Bjork-Shiley valve, 28 patients with the Ionescu-Shiley valve, and 33 patients with the St. Jude valve), mean transmitral pressure gradient and pressure-half time were estimated by continuous wave Doppler echocardiography five to fifteen days after operation. 1) PEP/AT Ratio by pulsed Doppler echocardiography correlated well with the mean pulmonary arterial pressure gradient by cardiac catheterization (r=0.83, p<0.001). 2) After mitral valve surgery, PEP/AT ratio decreased significantly (p<0.001). In group with mean pulmonary arterial pressure equal to or greater than 40mmHg, immmediate postoperative PEP/AT ratio was greater (P<0.05) than that in group with mean pulmonary arterial pressure less than 20 mmHg, but, difference between the preoperative and postoperative PEP/AT ratio was much greater (P<0.001) than that in group with mean pulmonary arterial pressure between 20 and 39 mmHg. 3) In 13 patients, on whom repeated Doppler echocardiography performed, PEP/AT ratio decreased immediately after mitral valve surgery (p<0.001). After then, it decreased further, but, the amount of the decrease was much smaller than immediate one (p<0.001). 4) There was no significant difference in postoperative PEP/AT ratio among the different prosthesis. Mean transmitral pressure gradient and pressure half-time of the Bjork-Shiley, Ionescu-Shiley, and St, jude valves were 3.1 mmhg and 67.3 msec, 2.9 mmHg and 65.3 msec, and 2.7 mmhg and 60.2 msec, repectively. The St.Jude valve had somewhat smaller mean transmitral pressure gradient and pressure half-time, but there was no statistical significance. In conclusion, elevated pulmonary arterial pressure in patients with mitral valve disease decreased greatly within 15 days after operation, and Doppler echocardiography was a useful method in the follow-up of prosthetic mitral valve function.

In order to determine the electrophysiologic properties of aberrant ventricular conduction we analyzed the electrophysiologic studies done for various reasons in SNUH(1983.3 -1987.8). All patients did not have underlying heart disease and were in sinus rhythm with normal PR intervals & no intraventricular conduction delay at the time of study. The patients of preexcitation syndrome were excluded. Only aberrant ventricular conduction induced by premature atrial stimulation at the high right atrium or(HRA) during sinus rhythm or HRA pacing was analyzed. 1) Aberrant ventricular conuction was induced by premature atrial extrastimulation in 34 subjects of 156 cases reviewed(21.8%). The patients were 16 to 70 years old(sixteen males and eighteen females). 2) The longest atrial coupling(A1S2) interval resulting in aberrant ventricular conduction approximated 45%(600-280) of the basic cycle length(450-1550 msec). 3) As a prerequisite for aberrant ventricular conduction, the functional refractory period(FRP) of the AV node should be less than the relative refractory period(RRP) of the His Purkinje System and the most important determinant of aberrant ventricular conduction by atrial extreastimulation was resultant H1H2 interval, which should be between RRP and effective refractory period(ERP) of HPS. 4) There was good linear correlation between the basic cycle length(BCL) and RRP of the HPS(RRP=0.247xBCL+247.048, r=0.885, p-value<0.001). 5) 155 different configurations of aberrant ventricular conduction were recorded during atrial extrastimulation till atrial ERP. The pattern frequencies were as follows : left anterior hemiblock, 6(3.9%) ; right bundle brach block, 92(59.4%) ; left bundle branch block, 28(18.0%) ; left anterior hemiblock combined with right bundle branch block, 14(9.0%) ; left posterior hemiblock combined with right bundle branch block, 9(5.8%) ; unclassified intraventricular conduction disturbances, 6(3.9%). 6) As the atrial coupling intervals were further shortened, aberrant conduction persisted up to the point of atrial ERP at 19/41 BCL's(46.3%). Other patterns of atrioventricular conduction were as follows : atrio-His block, 7(17.1%) ; His-ventricular block, 6(14.6%) ; normal conduction due to prolonged A2H2, 9(22.0%). But there was no statistical significance between the pattern of A-V conduction and the longest S2H2 & H2V2 intervals during VAB (p-value=0.235>0.050). In conclusion, atrial extrastimulation which is routinely done during clinical EPS is an effective method to induce aberrant ventricular conduction and to study the electrophysiologic characteristics of atrioventricular conduction. Further study with recording of bundle branch electrogram, after infusion of cardioactive drugs and pacing of HRA at fixed rate should be done to determine the electrophysiologic properties of VAB more completely.
