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.

Aberrant left-sided pulmonary artery(pulmonary artery sling) is an uncommon anomaly, which may cause significant respiratory abnormality. We report a case of pulmonary artery sling which is combined with persistent left superior vena cava and dextrocardia. This case was identified by esophagogram and CT and confirmed by MRI and angiography. We consider that MRI is a valuable new method for the diagnosis of aberrant left-sided pulmonary artery.

Authors performed 25 corneal grafts in 24 patients since the inauguration of The Central Eye Bank, attached to the Department of Ophthalmology, St. Mary's Hospital, Catholic Medical College, in April 19, 1967. Method and results of these cases are as follows; METHOD: In technique of surgery, the grafts in most of the cases were 7 mm in diameter(Table 3), in two types of penetrating and lamellar corneal grafts(Table 4). The donor material came from patient age group of 51-60 years old in most and was used within 24 hours after death (Table 5). In most cases we placed 12 interrupted sutures except of two cases for continuous suture by 8-0 virgin silks. Preoperative and postoperative cares were routine with systemic dexamethasone, 7.0mg a day was given routinely on the 5 th postoperative day for 30-50 days because of prevention of graft rejection. RESULTS AND SUMMARY: Table 7 summbrizes the results of our observation. Nineteen of the 25 grafts remained clear. And there was improved vision above 20/200 in ten eyes out of nineteen clear grafts. Table 10 lists the reasons why nine clear grafts did not improve vision. Postoperative complications occurred in fourteen grafts (Table 11). Penetrating corneal grafts for adherent leucoma courneae, staphyloma corneae and corneal scars from alkaline burn were failed to maintaining the clear graft. The donor material, the recipient cornea, graft rejection as a complication and its prevantion were discussed.

The variations of the sigmoid sinus were studied in 50 Korean adults (average age 67). The classification of the shape and a measurement of the diameters of the sinus were done and the morpological. 1. The shape was classified into 4 types, and the round type was the most common in both sides. S shaped type was below 10% in both sides. 2. The breadth was regular in 54% of the right and in 70% of the left sinuses. According to the breadth change, the shape was classified into 4 shapes. 3. The average diameter was 8.6mm on the right side and 7.2mm on the left side. 4. Symmetry was present in 16% of all. 5. The right transverse sinus was absent in 1 case (2%) and the superior petrosal sinus did not open into the sigmoid sinus in 2 cases (4%). 6. Petrosqamous sinus was observed in 16%.

Acute cerebral embolism continues to be a major cause of stroke morbidity in children and young adults. A variety of drugs including steroids, dextran, barbiturates, and anticoagulants are used in the management of cerebral ischemia, despite controversy over their benefits in clinical and experimental situations. The operative treatment includes microsurgical cerebral embolectomy and cerebral revascularization. Middle cerebral artery embolectomies which have been carried out in human with variable results, have been reported by different authors. In order to define a time limit for cerebral embolectomies before irreversible brain damage has been incurred, the canine middle cerebral artery was embolized by means of a gutta percha cylinder, 4 mm long by 1.5 mm in diameter, via the internal carotid artery. It was observed that embolectomy of the middle cerebral artery performed between 4 and 5 hours postembolism could prevent the expected cerebral infarction effectually. Middle cerebral artery embolectomy beyond 5-hour periods invariably resulted in severe hemorrhagic infarction with concomitant neurological impairment.

The permeability in vitro of rabbit corneal epithelium alone and whole cornea to four radioactive substances of various molecular weights-tritiated water (THO: molecular weight 22), mannitol (molecular weight 182), inulin(molecular weight 5,175), and dextran(molecular weight 77,500)-was directly measured by using a newly designed lucite chamber (Fig.1) and a proportional counter system for radioisotope experiments. The permeability of the corneal epithelium and the whole cornea varied with the size of molecular weight (Fig.4) and curvilineally with respect to molecular radius (Fig.5). Certainly the data (Table 2 and 3) support that the greater part of non-electrolyte permeation was through intercellular spaces passively. The epithelial or whole corneal permeability fell markedly as the molecular weight increased from 22 to 5,175. Above the molecular size of inulin, the permeability decreased much as the molecular weight increased. Generally, tritiated water permeability was about 150 times greater than that of mannitol and about 2,000 times than that of inulin and about 10,000 times than that of dextran. The difference between the permeability of the epithelium alone and that of the whole cornea was not noticed. Futhermore, the permeability, either of epithelium alone or the whole cornea, did not vary significantly depending upon the location of the hot side with any of the four kinds of isotope-labelled solutes, whether it was set at the epithelial or endothelial side of the corneal membrane (P>0.1). These results may support that the epithelial layer plays a main role as a physical barrier for nonelectrolyte solutes movement across the rabbit cornea.

OBJECTIVE: This study was designed to evaluate the efficiency of tumor markers level for early diagnosis of ovarian malignancy and for differentiation between benign and malignant ovarian tumors. MATERIALS AND METHODS: We determined preoperative serum tumor markers level in patients who were going to have an operation due to ovarian tumor in OB & GY Dept. of Chonnam University Hospital from April 1993 to September 1999. RESULTS: 1) The average values of serum tumor markers in patients with malingnant ovarian tumors were statistically higher than those of benign ovarian tumors. among malignant ovarian tumors, positive rate of all serum tumor markers was highest in epithelial ovarian carcinoma group. and among ovarian tumor markers, and positive rate of CA 125 was highest in epithelial ovarian carcinoma. 2) Dermoid cyst and endometioma were correlated to CA 19-9, CA 125 levels respectively. for malignant tumors, mucinous ovarian adenocarcinoma and non-mucinous ovarian adenocarcinoma were CA 19-9, CA 125 levels respectively. 3) Among ovarian tumor markers, CA 125 was the most in sensitivity and CA 72-4 was the most in specificity and diagnostic efficiency. 4) For postmenopausal women with ovarian tumors, elevated levels of at least one of the 4 tumor markers were present in the serum in 85.7% of the women who developed cancer, 62.5% of women with borderline, 27.8% of women with benign ovarian tumors. Conclusion; It is suggested that determination of serum tumor markers in patient suspected of ovarian tumor may be helpful to clinician for early diagnosis, differentiation between malignant and benign ovarian tumors.
