To study factors related to release of atrial natriuretic polypeptide(ANP) in human subjects, instracardiac pressure and plasma ANP concentration in peripheral and central circulation were measured in patients with various heart disease (18 valvular heart disease, 4 congenital heart disease, 2 cardiomyopathy). 1) The concentration in peripheral venous plasma were increased in 14 patients with New York Heart Associaion (NYHA) functional class III-IV (87+/-38 pg/ml) as compared with that in 10 patients with NYHA functional class I-II (39+/-21 pg/ml, P<0.005)and 15 normal subjects (51+/-21 pg/ml, P<0.01). 2)The concentration of plasma ANP in inferior vena cava, right ventricle, pulonary artery, left ventricle and aorta were markedly increased in patient with NYHA functional class III-IV, elevated mean right atrial pressure (MRAP> or =8 mmHg) elevated mean pulmonary capllary wedge pressure (MPCWP> or =15 mmHg) and/or elevated pulminary artery systolic pressure (PASP> or =35 mmHg), as compared with those in patients with NYHA functional class I-II and/or lower intracardiac pressure (MRAP<8 mmHg, MPCWP<15 mmHg, and/or PASP<35 mmHg). 3) A step up in ANP concentration between inferior vena cava and right atrium was seen in patients with elevated MRAP (81+/-28pg/ml, 137+/-60pg/ml, P<0.05), MPCWP (74+/-37pg/ml,112+/-62pg/ml, P<0.05) and/or PASP (75+/-29 pg/ml,119+/-64 pg/ml, P<0.05). But there were no differences among intracardiac ANP concentrations from right atrium though aorta. 4) Plasma concentrations in right atrium, pulmonary artery, left ventricle and aorta correlated with MRAP (r=0.82, 0.63, 0.56, p<0.005 and r=0.52, P<0.01, respectively), MPCWP (r=0.86, 0.75, 0.73 and 0.72 respectively, P<0.005 in all) and PASP (r=0.73, 0.57, 0.68 and 0.59 respectively P<0.005 in all). 5) Left atrial diameter correlated with plasma ANP concentration in peripheral plasma (r=0.55, P<0.01), inferior vena cava (r=0.51, P<0.025), right atrium (r=0.45, P<0.05), right ventricle (r=0.55, P<0.01), pulmonary artery (r=0.52, P<0.01), left ventricle (r=0.55, P<0.01) and aorta (r=0.56, P<0.005). These results suggest that the heart secrets atrial natriuretic polypeptide into right atrium in response to increased mean right atrial pressure, mean pulmonary capillary wedge pressure, pulmonary artery systolic pressure and/or left atrial distention.

The intramedullary nailing is one of the most available method in the treatment of femoral shaft fracture. Since the development of Küntscher nail in 1940, new designs such as the Grosse-Kempf interlocking femoral nail, Ressell-Taylor Femoral nial, AO/ASIF universal nail, ACE titanium nail became widely used by more applicable level of femoral shaft fracture. But complication of intramedullary nailing was rarely seen. The authors analyzed the clinical and mechanical factors predisposing to failures of intramedullary interlocking nails in 6 cases whom treated the comminuted fracture of the femoral shaft, at the department of orthopaedic surgery, Sun General Hospital from 1991 to 1995 and the following results are obtained. 1. Initial fracture patterns were comminuted in all 6 cases. 2. The implant nails were AO nail in 4 cases, Grosse-Kempf nail in 1 case, Russell-Taylor nail in 1 case(nail diameter was 10mm to 12mm). 3. The failure sites of the interlocking nail were the initial bone fracture site in 2 cases, distal to the proximal screw hole in 1 case, proximal to the distal screw hole in 2 cases, fracture site and distal to the proximal screw hole in 1 case. 4. The average time to failure of implants were 11.5 months. 5. The average times to partical weight bearing were 6.3 weeks. In the analy of above results, by using diameter of nail more than 13mm and delaying weight bearing on the injured limb until there is clear radiographic evidence of early union of the femur fracture, we may reduce the metal failures of intramedullary interlocking nail in comminuted femoral shaft fractures.

Multipe Evanescent White Dot Syndrome is a clinical disorder of unknown etiology usually resulting in acute visual loss It affects primarily the retinal pigment epithelium and photoreceptors, Ocular manifestations may include multiple white dots at the level of the retinal pigment epithelium, granulaity of the macula, optic nerve swelling and anterior chamber and vitreous cells. Fluorescein angiogram discloses hyperfluorescence in association with the white spots and late staining and dye leakage from disc capillaries. We experienced a case of Multiple Evanescent White Dot Syndrome and reviewed the available literatures regarding this disease.

Since Purtscher's original discriptions similar clinical signs have been described following acute compressive neck or chest injuries, chest compression, val salva maneuvers, long bone fractures, acute pancreatitis and after childbirth. The appearance of Purtscher's retinopathy are believed to be due to ischemic episodes particularly in the end arterioles around the macula and disc. We experienced two cases of Purtscher's-like retinopathy in patients with systemic hypertension who had not any recent trauma history and reviewed the available literatures regarding this disease.

23 eyes of 23 patients who underwent conventional vitreoretinal surgery with high specific gravity perfluorocarbon liquid, perfluorophenanthrene, for complicated retinal detachment were evaluated retrospectively. Preoperative vitreoretinal findings showed grade C2 PVR in 4 eyes and C3 in 1 eye and C4 in 10 eyes and C5 in 8 eyes. As a result, 17 eyes(74%) showed anatomical success, completely reattached in 15 eyes, partially reattached in 2 eyes, and 12 eyes(52%) showed functional success (corrected visual acuity 5/200 or better). Follow-up period was over 6 months in all cases. Postoperative complications includes keratopathy in 6 eyes, hypotony in 5 eyes, cataract in 2 eyes, transient vitreous hemorrhage in 1 eye, acute increased IOP in 1 eye, posterior synechiae in 1 eye, cystoid macular edema in 1 eye, and pupillary membrane in 1 eye. Consequently, perfluorophenanthrene can be used beneficially in yield of surgical field and mechanical stabilization of retina in complicated retinal detachment surgery.
