Photorefractive keratectomy (PRK), Keratomileusis In Situ (KM), Laser Assisted In Situ Keratomileusis (LASIK), and clear lens extraction have been performed for high myopic patients. Among the above surgical procedures KM and LASIK are applied to young patients in general. However, comparison of clinical results of these two procedures was not reported yet in Korea. To evaluate the clinical results of KM (n=16) and LASIK (n=11) for high myopic patients between -15 diopter (D) and -23 diopter (D), spherical equivalent (S.E) and uncorrected visual acuity were studied for more than ten months, retrospectively. The mean S.E. was changed from -17.36 D before operation to -3.70 D ten months after operation in KM, whereas it was from -17.41 D to -0.31 D in LASIK. At ten months after operation, uncorrected visual acuity equal or better than best corrected visual acuity before operation was 43. 8% in KM and 63. 6% in LASIK. This results show that the clinical result of LASIK were superior to that of KM for high myopia.

Two cases of leukemia cutis associated with leukemia has been demonstrated. Case 1: 24 year old man had been fever, arthralgia and leproma like hard infiltrated nodular lesion with hemorrhagic macules was noted on face and upper arms and trunk, Monocytic Jeukemia has been presented. In peripheral blood and bone marrow finding, immature blood cells was counted in about 80%, Case 2: 64 yearold woman, had been erythematous papule with itching on lower extremities and coin ized ulcerated nodule was noted on lumbosacral region. Myeloid leukemia has been presented. In peripheral blood and bone marrow finding, immature blood cells was counted in about 7.2%. Diagnosis of cutaneous lesions was by clinical apperance and histopathological change. By laboratory examination, monocytic leukemia and myeloid leukemia was revealed in peripheral blood and bone marrow preparation.

The parathyroid cyst is a relatively uncommon disease and usually identified during the operation for a presumed thyroid mass. Thirteen cases of parathyroid cyst (2 males, 11 females) treated from 1981 to 1993 were reviewed. Ages ranged from 17 to 59 years(mean, 41 years). Gross measurement of the tumor size varied from 1.0 to 10.0 cm in diameter with a mean of 4.8cm. All of the 13 patients presented with a chief complaint of painless anterior cervical mass. Only one complained of mild symptom of dyspnea and voice change due to huge cyst in paratracheal space. No functional cyst was identified. Diagnostic studies included ^99mTc thyroid scan (n=11), ultrasonography (n=10), computerized tomography (n=4) and fine needle aspiration(FNA) (preoperative, n=4; intraoperative, n=3). All diagnostic precedures but needle aspiration were nonspecific. Cysts were found in right inferior parathyroid(n=4), left inferior parathyroid (n=7), or anterior superior mediastinum (n=2). The FNA of the cyst contents revealed watery clear fluid with elevated parathyroid hormone level and was diagnostic in each cases. Four patients were treated initially with needle aspiration, of which only one patient was successful, and 3 patients who were unsuccessful to needle aspiration and the remaining 9 were effectively treated with surgical extirpation. Our experience suggested that needle aspiration may be of significant help in diagnosis and treatment of parathyroid cyst, but most of the patient could be treated successfully by surgical extirpation with an excellent chance for curability.

This experiment was aimed to investigate the contractile responses of the fermoral artery to the electrical stimulation and the inhibitory effects of verapamil and papaverine on the electrical stimulation of the fermoral artery in the control (n=46) and the diabetic rabbits(n=40). Diabetic rabbits were made by and administration of alloxan (100 mg/kg) intravenously and sacrified 8 weeks later. Femoral arterial rings 3 mm in length were taken and mounted on the force-displacement transducer for the measurements of isometric tension. All experiments were done in the aerated (95% O2 with 5% CO2)biological chamber filled with Kreb's solution and the initial tension of 1.5g was applied to the rings. After 1 hour of equilibrium of the rings, the contractile responses of the electrical stimulation on the femoral arterial rings were taken without vasoactive drugs and then, under verapamil and papaverine solution. And we compared the morphologic findings of the vessels in the two groups in relation to the functional changes by transmission electron miroscopy. The results are as follows: 1. The contractile responses in the presence of verapamil or papaverine solutions to the electrical stimulation were lowed significantly in the fermoral arterial rings of the diabetic rabbits compared with that of the control rabbits (verapamil; 10M~10M: p<0.01, papaverine; 10M & 10M: p<0.01). 2. Transmission electron microphotographs showed many morphological differences of the femoral arteries between the control and the diabetic rabbits. These were irregularities of the internal elastic lamina and the hypertrophy of the cytoplasms of the smooth muscle cells. And also, there were many vacuoles in the cytoplasm of the endothelial cells, lateral to the internal elastic laminaes, and between the smooth muscle cells in the diabetic rabbit femoral artery. By this study, we found that the contractile responses of the femoral arterial rings to the electrical stimulation were decreased in the diabetic rabbits, and the vasodiatory effects of verapamil and papaverine on the electrically stimulated femoral arterial rings were also lowered in the diabetic rabbits compared with the control rabbits. These changes of the vasular responses of the diabetic vessel may be associated with morphological changes manifested by transmission electron microscopy or any other functional derangement of the vessels.
