Ketalar, a new parenteral anesthetic, was used as a clinical trial for 14 surgical cases ranged from 2 to 15 year old children, and also intraocular pressures of their patient's sound eyes were measured before and after Ketalar injection, I.M. 5-10 mg/kg. Unlike conventional anesthetic agents, Ketalar caused a significant rise in intraocular pressure within 5 minutes and then the pressure improved to normal range about 15 minutes after Ketalar injection. Ketalar could not recommended as a general anethetic agent in case who should examine the intraocular pressure. In eye surgery under 15 year old children, this agent would be a safe and effective general anesthetic, and in an emergent eye injured case, Ketalar is an agent of first choice and can injects to patient regardless of diet intake.

In search of the effect of air pollution on the eye, the authors examined ocular symptoms and diseases in both an urban(Seoul) and two rural populations (Suwon and Changsung). The Prevalence rate of ocular symptoms and diseases between 109 occupational drivers of more than 3 years career in Seoul area which is one of the air polluted urban areas and 150 populations in the two different rural areas as a control group were compared. The prevalence rate of ocular symptoms was 89% in Seoul, 10% in Suwon and 23% in Changsung area, and those of ocular diseases were 35%, 6% and 10% in the same areas, respectively. The prevalence rate of ocular symptoms and diseases is respectively 3 to 4 times more prevalent in occupational drivers than in the control groups. Many other etiologic factors such as occupation, labor condition, environmental stress or different way of living may influence the prevalence rate between the two groups, however, it would be presumed that the main causative factor to cause ocular symptoms and diseases is probably due to air pollution.

The authors analysed statistically 223 cases of the eye injuries among 17,547 out-patients who visited to our clinic located at down-town of the city during Jan. 1965 to Sept. 1967. The incidence of the eye injuries is remarkably lower than the other reports from other communities. As far as the objects of eye injuries were concerned, ironpiece, fist and coal-dust were more frequent in 21~40 year-age group, while in under 10 year age group, knife, nail and finger-tip were more frequent. Male was exceedingly prevalent (162) than female (61). 21~30 year age group was also prevalent in regard to the incidence of the injuries.

We have reviewed our experiences of computerized tomography(CT) in the fracture of the spine. Between December 1983 and June 1985, we treated 33 fractures of the spine in 32 patients. We have used CT for the diagnosis of fractures of the spine in 29 cases (28 patients). Also we have used Louis scoring system to evaluate the stability of the fractured spine. The results are as follows. 1. CT has many advantages that were not given from simple radiograp hies or laminagrams. It reveals the vertebral body, vertebral column, posterior compartments and surrounding soft tissues excellently, and it is easy to interpretate. Also it can be done comfortably and rapidly without the need of manipulations. 2. We could acquire many informations from post-operative or long term following up of CT examinations. 3. If the Louis score is higher than 3, we should think it is unstable, and should take internal fixation of the vertebral column. 4. There is a correlation between Louis score and neurologic signs (p < 0.01). If there was a neurologic sign with low Louis score, less than 1, the recovery was soon, less than 24 hours. 5. According to CT findings for fragmentation or location of fragment, we can alternate an anterior decompression or a posterior decompression. 6. It is necessary to use CT as a initial diagnostic procedure with the simple radiographic examination in spine fracture.

We have experienced a reexpansion pulmonary edema(RPE) during general anesthesia. This patient has undertaken the decortication operation due to right sided massive pleural effusion and fibrothorax. Generally reexpansion pulmonary edema is believed to oceur only when a chronically collapsed lung is rapidly reexpanded by evacuation of large amount of air or fluid in pneumothorax and pleural effusion. The pathogenesis of RPE is unknown and is probably multifactorial. The implicated etiologies are chronicity of collapse, technique of reexpansion, increased pulmonary vascular permeability, airway obstruction, loss of surfactant and pulmonaty artery pressure changes. The outcome of RPE may be fatal, so physician treating lung collapse must be aware of the possible causes and endeavor to prevent the occurrence of this complieation.

1. INTRODUCTION: It is well known that a successful corneal graft depends primarily on the viability of corneal endothelium. And also corneal endothelial viability of donor eye is largely varied from the duration of storage time of enucleated eyes. It is generally agreed that penetrating corneal graft should be done within 48 hours when donor cornea was stored in moist chamber at 4 degrees C because of corneal endothelial viability. But there is some other opinion about the storage time as the school of Filatov insists that donor cornea could be storaged for 4~5 days before corneal graft. The permeability of the cornea is significant from several viewpoints, first, the nutrition of the cornea depends on the diffusion of oxygen and glucose and other substances from the surrounding fluids. Second, the transport of drugs or other substances across the cornea is determined by the permeability of the corneal layers. Present experiment involves the direct measurement for changes of tritiated water permeability, K trans, of rabbit corneal endothelium stored at 4 degrees C up to 5 days. 2. MATERIALS AND METHODS: Adult albino rabbits, weighing 2~3 kg. were killed by intravenous injection of air administered via the marginal vein of an ear. if more moist chamber bottles are prepared than needed for immediate use of enucleated eyes, they more stored at 4 degrees C in the refrigerator for periods of 24, 48, and 120 hrs. Preparation of endothelium was made simply by remove of the epithelium with gouze (Kim et ai, 1971). The remaining stroma was requisite as a mechanical support for th endothelium. And then a puncture incision was made through the sclera 1~2 mm peripheral to the limbus, and a circumferential cut was made at the same distance from the limbus. The excised tissue was then transferred immediately to a Petri dish containing Ringer's solution at 35 degrees C, and the lens and the iris were carefully removed together with any connective tissue that was attached to the sclera. Finally, the cornea with its scleral rim was mounted in a lucite chamber which was designed specially to hold the convex tissue(Fig. 1). After the tissue was mounted, the chambers were quickly filled with the experimental solution. The solutions on both sides of the tissue were stirred with Teflon-coated magnetic stirrer driven by horseshoe magnets rotating at 400 rev./min to reduce the rete-limiting effect of an unstirred layer on solute movement (Dainty, 1963). The composition of the experimental solution, based on normal (Krebs-bicarbonate) Ringer's solution, was presented in Table I (Green, 1965). A sufficient volume of solution for each experiment was brought to the required temperature(25 degrees C) immediately prior to the experiment. Radioisotopes 3H-labelled tritiated water(THO. specific activity, 5 mCi/ml; Molecular weight, 22) was obtained in solution form (Amersham Radiochemical Center, Buckinghamshire, England). A tracer amount of the radioactive substance to be studied, in normal Ringer's solution, was introduced into the chamber facing the endothelial surface and its rate of appearance on the other side was then determined. Samples (50 micro l) were taken with a micropipette (25 micro l) initially from both bathing solutions 1 hr. after addition of the solutions to the tissue, but thereafter only from the cold side at 60 minutes intervals for 3 hr duration. The samples were transferred to planchets which were then placed on sample spinner; a volume of methyl alcohol was added sufficient to cover the planchet and to allow even spreading of the sample which drying under on infrared lamp. The activity of the radioisotope samples were then assayed using a NMC Proportional Counter System, Model PC-3A, U.S.A. The permeability coefficient, K trans., for this radioactive substance, defined as the amount of the given substance crossing 1cm2 of membrane surface per second under a driving force of unit concentration gradient was calculated according to Maffly et al (1960). 3. RESULTS AND COMMENTS: The permeability coefficients, K trans., of fresh corneal endothelium as a control and the corneal endothelium stored AT 4 degrees C moist chamber in the refrigerator for different lengths of time were presented in Table 2, all these permeabilities were measured on highly swollen stromas since permeability determinations were not begun until 1 hr after exposure to the isotope solution. The rate of passage of tritiated water through the endothelium (plus stroma and Descemet's membrane) stored at 4 degrees C showed the linearity of the increasing count rate against time (Fig. 2). A rise in tritiated water permeability occurred in those stored for 48 hrs. and then followed by a fall in those stored for 120 hours, which there was no significant difference (p>0.3) in comparing with the permeability of fresh corneal endothelium used immediately after enucleation. It presumed that such a finding is due probably to the vitality change of the endothelium. Such a similar results were also obtained by a method of oxygen uptake by corneal endothelium of eyebank eyes stored at 4 degrees C for up to 6 days(Preziosi, 1971).

The permeability of rabbit corneal endothelium stored at 4 degrees C in M-K medium for period of 3, 5, 9 and 14 days to radioactive sucrose(molecular weight 360), inulin (molecular weight 5,200), and dextran (morecular weight 82,400) was measured. The corneal endothelium stored in M-K medium up to 14 days was examined with light and electron microscope. The endothelial permeability to non-electrolytes was decreased according to the molecular weight of these increased. The permeability of fresh cornea to suerose was about 4 times greater than to inulin and 50 times than to dextran, but in M-K medium stored groups the permeability to sucrose was about 2.5 times greater than to inulin and 36 times than to dextran. The permeability of M-K medium preserved cornea for 14 days was significantly different from that of fresh corneal endothelium. The light and electron microscopic findings of 3, 5 and 9 days stored corneal endothelium were almost normal except of early changes of mitochondria, but in the 14 days-stored groups there were marked degenerative change of cytoplasm and nucleus were noted.
