Transmitral left ventricular diastolic inflow velocities determined by pulsed Doppler in 47 normotensives, 80 hypertensives and 44 age-matched hypertensives were measured to evaluate the effects of age and left ventricular hypertrophy on left ventricular diastolic fuction in normotensives and hypertensives. The results were as follows: 1) The peak E velocity in normotensives(77.82+/-13.53cm/sec) was significantly different from those of hyeprtensives(58.13+/-11.80cm, p<0.01) and age-matched hypertensives(59.31+/-10.94cm/sec, p<0.01). The peak E/A in normotensives(1.31+/-0.45) was significantly different from those of hypertensives(0.83+/-0.21,p<0.01) and age-matched hypertensives(0.83+/-0.20, p<0.01). 2)In normotensives, simple linear regression analysis revealed strong inverse correlations of peak E with age(r=-0.758, p<0.01), peak E/A with age(r=-0.748, p<0.01), but no significant correlation of peak E and peak E/A with LVMI(p>0.05). Stepwise regression analysis revealed that age was the most important correlate of peak E and peak E/A in normotensives(peak E: R

In case of severe blepharoptosis, frontalis muscle suspension with fascia or frontalis transfer has been popular for decades, but these static procedures have some disadvantages such as lagophthalmos, lid lag and remnant ptosis. Twenty-six patients with severe blepharoptosis who underwent frontalis suspension, frontalis transfer, or levator resection at Yonsei University Severance Hospital from 1980 to 1988 were studied. The follow-up period of patients ranged from 10 to 18 years with a mean of 12 years. Surveys and clinical results were obtained, In our review of postoperative complications, lagophthalmos persisted in sleep and even in forced eye closure in most patients 2 to 6 months after operation. But no recurrence was noted. In conclusion, undercorrection of ptosis is more desirable than overcorrection. As well levator resection can be considered in selected cases to prevent complications.

BACKGROUND: The obese patients increased recently in Korea due to excessive energy intake and decreased physical activity. We are well known that obesity is associted with an increased risk of cardiovascular disease, angina pectoris, hypertension, but not known to influence of weight gain to change in cardio-vascular risk factors. Once, the study of obesity are many but the study of influence of weight gain are small in Korea. This study investigated to influence of weight gain in cardio-vascular risk factors. METHODS: We gatherd case and control group among persons who has taken twice medical examination except disease person from October 1990 to October 1995 at SungAe General hospital. In our study, total 167 case, compare weight gain group(>3kg) with control group to change in cardiovascular risk factor. RESULTS: Sex, age, smoking history, obesity index were not statistically significant difference between two group in the first medical examination. systolic blood pressure, diastolic blood pressure, fasting blood sugar, HDL, total cholesterol/HDL were not statistically significant difference between two group for weight gain. Total cholesterol and triglyceride, LDL were stastistically significant increased. CONCLUSIONS: Weight gain was increased of total cholestrol and triglyceride, LDL, so weight control was important.

4.Effect of Experimentally Induced Anisometropia on Binocular Vision.
Journal of the Korean Ophthalmological Society 1999;40(12):3468-3473
We investigated the effect of experimentally induced anisometropia on binocular function. Unilateral myopia, hyperopia, or astigmatism(Axis 90degrees) was induced in eighteen adults with normal binocular function using softcontact lenses. Sensory status was assessed by measuring stereoacuity, Worth four dot test, and Bagolini lens test. Binocular function of all subjects decreased with increasing levels of anisometropia. In Worth four dot test, foveal suppression increased in proportion to the levels of anisometropia. Stereoacuity was similarly degraded by the induced anisometropia. Bagolinilens responses were normal in almost all subjects. Our study suggest that experimentally induced anisometropia cause significant abnormalities in binocular function in adults.

Schonlein-Henoch purpura is a generalized small vessel vasculitis characterized by nonthrombocytopenic purpura, arthritis, abdominal pain and nephritis. In 1914 Osler described an allergic purpura associated with hemiplegia. After then Lewis et al. reported the cases of Schonlein-Henoch purpura associated with convulsion, coma, confusion, intracranial hemorrhage, and chorea, CNS complication has been reported in 1-8% of children and subsided spontaneously in most cases. Headache is a remarkable sympton and appears nonspecific nature. In 1991 Ostergaard and Storm reported that headache occured during the first week following skin rash and frequently showed abnormal EEG findings. We investigated prospectively the presence of a possible cerebral and renal involvement in the case of Schonlein-Henoch purpura. EEG abnormality demonstrated in 52.6% of all cases, and headache or irritability in 47.4% of all cases. A significant association was found between abnormal EEG finding and presence of headache, but was not found between EEG findings and presence of renal involvement and hypertension. Patients with abnormal EEG had no Past or famity history of febrile convulsion or ididopathic epilepsy.

6.Effect of the Sitting Position after Spinal Anesthesia on the Incidence of Postdural Puncture Headaches: Saddle Block versus Low Spinal Anesthesia.
Journal of the Korean Society of Coloproctology 2004;20(1):15-19
PURPOSE: Postdural puncture headache is one well-known complications of spinal anesthesia. The development of postdurals puncture headaches is related to needle size, the direction of the needle bevel, the number of dural punctures and the age of the patient. However, the effect of the sitting position after spinal anesthesia (saddle block) on the incidence of postdural puncture headaches is not yet known. This study was performed to compare the incidence rates of headaches between a saddle block group (sitting position group) and a low spinal anesthesia group (supine position group). In addition, this study was performed to identify the predisposing factors influencing postdural puncture headaches (age, sex, seasonal variation, onset of headache, location of headache). METHODS: The authors analyzed 960 anal-surgery patients who were operated on using a saddle block or low spinal anesthesia at Hang Cinic from Jan. 2000 through Dec. 2000. The authors compared the incidence rates of headaches between the saddle block group (480 cases) and the low spinal anesthesia group (480 cases). RESULTS: 1) The incidence of postdural puncture headaches was not significantly different between the two groups (2.5% in the saddle block group, and 2.3% in the low spinal anesthesia group) (P>0.05). 2) The postdural puncture headache incidence rate was higher for younger patients (20~30 years) and for females. (M:F=7:16) (P<0.05). 3) The onest of postdural puncture headaches was at the postoperative 2nd day in 16 cases (70%) and at the postoperative 3rd day in 6 cases (26%). 4) The incidence rate of postdural puncture headache was higher in the summer (5 cases in June, and 3 cases in July, 4 cases in August). 5) The headache were located in the frontal region in 16 cases (70%) and in the occipital region in 3 cases (13%). CONCLUSIONS: There is no significant difference in the incidence rates of postdural puncture headaches between the saddle block group and the low spinal anesthesia group. Postdural puncture headaches had a tendency to occur more frequently in young female patients and during the summer season. In addition, a more intensive study of the use of saddle block anesthesia for ambulatory anal surgery is required.

7.Comparison of 2-Octylcyanoacrylate and Suture with 8-0 Polyglactin for Conjunctival Wound Closure in Rabbits.
Journal of the Korean Ophthalmological Society 2005;46(5):896-903
PURPOSE: To evaluate the clinical efficacy and the histopathologic tolerance of 2-octylcyanoacrylate versus 8-0 polyglactin sutures for conjunctival wound closure in rabbits. METHODS: We performed an experimental study on 16 eyes of eight New Zealand albino rabbits. Conjunctival peritomy of 8 mm was done in the superior limbus followed by extensive subconjunctival dissection in both eyes. The eyes of the rabbits were divided into two groups. The conjunctiva was then attached to the limbus again by the proposed 2-octylcyanoacrylate adhesive (left eye, Group A) or 8-0 polyglactin suture (right eye, Group B). The clinical efficacy of the closure of the conjunctival wound, either with sutures or adhesives, and the clinical and histopathologic tolerances such as hyperemia, discharge, residual adhesive or suture, inflammatory change and fibrosis were observed at 1 day and at 1, 2, 4 and 6 weeks after surgery. Two rabbits were sacrificed at each of 1, 2, 4 and 6 weeks, and specimens of their conjunctiva were examined histologically. RESULTS: Both conjunctival surgical closure methods were found to be equally efficacious in fixing the conjunctiva to the limbus. There were no significant clinical or histopathologic tolerance differences between the two groups. The conjunctiva at 6 weeks of Group A showed nearly normalized morphology with disappeared inflammatory cells and fibroblasts, whereas those of Group B showed foreign body inflammatory reaction around the absorbing suture materials. CONCLUSIONS: 2-Octylcyanoacrylate adhesive was an efficient conjunctival closure method and was very well tolerated by the ocular surface. 2-Octylcyanoacrylate may be a possible tissue adhesive for conjunctival wound closure.

Journal of the Korean Ophthalmological Society 2002;43(9):1758-1766
PURPOSE: The therapeutic effects of amniotic membrane transplantation (AMT) contain anti-fibrosis, anti-inflammation and facilitation of epithelialization. Thus we investigated whether applying of amniotic membrane (AM) ointment could get the same effect as AMT. METHODS: Alkali burn was induced by applying 6 mm round filter paper which was soaked with 1 N NaOH, onto the central cornea for 60 seconds on both eyes of 10 white rabbits. Then we applied AM ointment on one eye and base ointment on the other eye, four times a day for 1 week. The corneas were harvested for histopathologic studies at 1 day and 3 weeks. Corneal opacity and thickness were measured in 3 days and 1, 2, 3 weeks. RESULTS: In the AM ointment applicated group, the number of the infiltrated PMNs (polymorphonuclear cells) and apoptotic keratocytes were significantly less than that of the control group (p< 0.05). The degree of lipid peroxidation and myofibroblast differentiation were less than those of the control group. Corneal opacity and corneal edema were less in AM ointment group than control group. CONCLUSIONS: AM ointment application after alkali burn is beneficial to reduce inflammation, keratocyte apoptosis and lipid peroxidation, and is considered to suppress corneal haze by these effects. Therefore, this report may be a basic study for the AM ointment research to treat recalcitrant keratitis.

10.Blood Gas Changes in the Paturient and Fetus under General Anesthesia for Cesarean Section.
Korean Journal of Anesthesiology 1987;20(6):774-781
Anesthesia for Cesarean Section entails many considerations not pertinent to surgical patients. The anesthesiologist is required to provide anesthesia for mother and fetus simultaneously and to perform emergency anesthesia in high risk paturients with no preoperative evaluation. Variable phrsiologic changes in pregnancy in the cardiovascular, respiratory, gastro-intestinal and renal systems entrance the uptake of anesthetic gases and in the apneic status, PaO2 decreases significantly. During general anesthesia, maternal hypoxia, hyperventilation, aortocaval compression of the enlarged uterus and prolonged induction-delivery time may contribute to circulatory changes which may result in fetal hypoxia and acidosis Kalapa et at (1971) and Gibbs (1981) reported that balanced anesthesia is safe for Cesarean section as long as the time from induction to delivery (IDT) is not prolonged. Maternal arterial blood gases after induction and delivery and fetal umbilical arterial and venous blood gases were measured in 30 paturients under going Cesarean section with thiopental-SCC-N2O-O2 anesthesia (general balanced anesthesia). The relationship between IDT and the apgar score was also studied. The results were as follows : 1) Analysis of tole Paturients arterial blood gases after induction arid after delivery, had no statistical significance. 2) Blood gas analysis from the umbilical of the fetus was pH 7.36 +/- 7.04, PCO2 39.8 +/-3.7 torr, PO2 36.8+/-3.4 torr, BE -2.8+/-0.7 mEq/l and oxygen saturation was 72.2+/-5.8%. Umbilical arterial blood from the fetus was 7.31+/-0.03, PCO2 49.1+/-4.8 torr, PO2 25.9+/-4.7 torr, BE -2.6+/-0.6 mEq/I and oxygen saturation was 36.2+/-3.4%. 3) The results of blood gas tension and acid-base status of the paturient according to IDT were not Statistically Significant in any group- 4) The results of' the apgar score according to IDT indicated that the 1 minute apgar score was statistically singinificant but not clinically the 5 minute appear score was not statistically significant.
