New born rat heart cells were dissociated using trypsin and/or collagenase to elucidate the dissociation efficiency of these two enzymes. And the effect of dimethyl sulfoxide during and immediately after cell dissociation was also investigated to clarify the so-called protective activity of dimethyl sulfoxide on cell performance. The results can be summarized as follows. 1. Cold trypsin 18 hours pretreatment followed by warm collagenase treatment resulted best cell viability and cell yield. 2. Single warm trypsin treatment gave the poorest result. 3. Dimethyl sulfoxide did not seem to play any protective role during or immediately after rat heart cell dissociation. It had very damaging effect on rat heart cells.

One hundred seven consecutive patients aged 3 years to 34 years with simple ventricular septal defect were prospectively investigated with 2-dimensional Doppler echocardiography to assess the echocardiographic criteriae in defining the anatomic site of the VSD. The anatomy was confirmed in all patients at operation. Two-dimensional Doppler echocardiography correctly categorized the site and extension of VSDs in 104 of 107(97%). All doubly committed subarterial VSDs were correctly diagnosed as an area of discontinuity beneath the pulmonary valve in the parasternal short-axis plane taken at the aortic root level. Forty eight of 49 perimembranous VSDs with infundibular extension showed an area of discontinuity beneath the right aortic cusp in the parasternal long axis plane of the left ventricle. Of 17 perimembranous VSDs with trabecular extension, 16 had an area of discontinuity around the medial papillary muscle in the short axis plane taken at the level of high left ventricular outflow tract(LVOT). All 5 perimembranous VSDs with inlet extension showed an area of discontinuity adjacent to the septal leaflet attachment in the short axis plane taken at the level of high LVOT. One muscular trabecular VSD was categorized correctly by the short axis view and the apical 4-chamber view. Thus, these 2-dimensional Doppler echocardiographic criteriae are a simple and reliable in identifying the anatomic site of VSDs.

Six patients with exfoliation syndrome were seen in our glaucoma clinic. Four patients presented unilateral ocular involvement and the other 2 patients were bilaterally involved. Eight eyes had exfoliation material on the anterior surface of the lens and pupillary border, and 7 eyes exhibited it on the anterior chamber angle. Sampaolesi`s line was detected in 4 eyes. Five patients (6 eyes) of 6 patients (8 eyes) with exfoliation exhbited an elevated intraocular pressure (IOP) exceeding 21 mmHg. Among them, 3 patients (3 eyes) had an extremely high maximum IOP over 47 mmHg, and 2 patients (3 eyes) had a slightly elevated IOP less than 26 mmHg during the follow-up period. Argon laser trabeculoplasty (ALT) was performed twice on each unilateral eye of the 2 patients on whom the inital trabeculectomy failed. However, longterm IOP control after laser treatment was not obtained in either case, which might be due to the extremely high prelaser lOP level, in exoess of 40 mmHg.

The objectives of this study were to investigate the efficacy and dose-effect relationship for glycopyrrolate in the suppression of the oculocardiac reflex, and to compare glycopyrrolate with the reported equivalent dose of atropine. Glycopyrrolate 5 and 7.5ug/kg and atropine 10 and 15ug/kg were studied in 40 paediatric patients to assess more fully the dose of glycopyrrolate required for adequate prevention of the oculocardiac reflex. The results obtained were summarized as follows: 1) The increase in the mean heart rate 5 min after the test drug was statistically significant in all of the four groups. 2) Both drugs showed a dose-related response for reduction in slowing of heart rate after rectus muscle traction. 3) There is great individual variation in response to muscle traction within each group, no group being fully protected from marked slowing in heart rate. 4) The frequency of arrhythmias with low doses of both drugs was more than in high doses with both drugs.

The first comprehensive clinical description of exfoliation syndrome was published by Vogt. The appearance is described as a deposition of white granular fluffy material on the anterior lens surface, pupil margin, zonule, ciliary body and anterior chamber angle, and floating free in the aqueous. At past, this syndrome was thought to be rare outside of the Scandinavian countries, but the relatively high prevalence has been noted in many other countries outside of Scandinavia. The clinical significance of this syndrome is high frequency of glaucoma. Six cases in this report illustrate some of typical clinical features of exfoliation syndrome. The purpose of this study is to concentrate our attention upon the presence of this syndrome in Korea.

We have experienced automated and computerized perimetry using a Humphrey Field Analyzer in our Glaucoma Services. To evaluate its clinical efficacy, we report the results of the Armaly central field screening test in comparison with those of central 30-2 threshold test of the Humphrey Field Analyzer. One hundred fortythree eyes of 83 cases of normotensives, ocular hypertensives and glaucoma patients with open-angle or narrow-angle were enrolled in this study. Fiftyfour out of 61 patients (88.5%) and 73 out of 81 eyes (90.1 %) with visual field defect were detected by the screening test of the Humphrey Field Analyzer. Eight out of 81 eyes (9.9%) with visual field defect detected by the screening test were confirmed as false positive. All points of false positive were solitary, which tended to occur more frequently on superior vusual field. False negative of 8 eyes (12.9%) detected by the screening test were confirmed by the threshold test. The point of false negative was more frequent on superior field and showed to locate more peripherally from the fixation point. There was no significant difference in either central sensitivity or age of the false ring.
