To elucidate the argument on the hypertensive effect of repeated stress, morphological study on the juxtaglomerular apparatus of pain-stressed mice was carried out. Following the repeated stress on mice by subcutaneous injections of formalin every day, animals were sacrificed on 1, 3, 6, 12 hours and 1, 2, 3, 6 days after the 5th injection. Kidneys fixed in 10%, Zenker-formol solution were routinely processed, and 4um sections were stained by Bowie's stain. For the precise interpretation, following protocols were applied; Comparing the amount of secretory granules, juxtaglomerular granulation index (JGI) was weighted on every 1000 glomeruli according to their granulaities. Comparing the proportional appearance of juxtaglomerular apparatus, granulation cell index (GCI) was counted as a mean number of granular juxtaglomerular apparatus among every 100 glomeruli. Comparing the cellularities of a single juxtaglomerular apparatus, juxtaglomerular granular cell count (JGCC) was counted as a mean number of granular juxtaglomerular cells appearing in a longitudinally. sectioned afferent arteriole. Comparing the functional relationship between the juxtaglomerular cells and macula densa cells, macula densa cell count (MD count) was counted as the mean number of macular densa cells having contacts with granular juxtaglomerular cells. Result of this experiment was processed and interpreted as followings. 1. Repeated pain-stress give rise to the prominant effect to juxtaglomerular cells, as high as double granular amount as compared to normal one, during 3-6 hours after the last stress. 2. Functional relationship between the distal convoluted tubule and Juxtaglomerular cells, checked out by MD contacts, was also highest during 3 to 6 hours term. 3. The effects were decreased afterwards, but still most counts were higher than those of normal data until 6th day, the last term of this experiment. 4. Present study show that the repeated pain-stress initiate the significant pressure-rising effect to animals during the first day after the last stress, and these effects may be latent during some days afterwards. 5. As the precise mechanism involved in this aspect remains to be elucidated, further studies includingelectron microscopic and histochemical methods shall be suggested.

An analytic study on 431 cases of cardiac conduction disturbance has been made by review of the clinical records and electrocardiograms taken from the adult patients registered at Kyung Hee University Hospital for 3 years from May, 1973 to April, 1976. 1. The total incidence of conduction disturbance was 6.50%, the atrioventricular block 3.14% and the intraventricular block was 3.36% of total 6,616 cases of E.C.G. reviewed. Among of these, the first degree atrioventricular block was 3.02% which was the most common occurred one, the incomplete right bundle branch block was 2.25% and the complete right bundle branch block was 0.57%. 2. The ratio of male to female was 1.6:1 for the first degree atrioventricular block, and 1.6:1 for the incomplete right bundle branch block, 2.5:1 for the complete atrioventricular block, 2:1 for the left bundle branch block, and 1.7:1 for the complete right bundle branch block. The first degree atrioventricular block was seen most frequently in the fifth and sixth decade of age group, and the third degree block was over 40 years. The incomplete right bundle branch block in order was forth decade, third decade and fifth decade. The complete right bundle branch block and left posterior hemiblock were common in the sixth decade. The left bundle block and the posterior hemiblock were common in fifty years of age group. 3. The cardinal underlying diseases of the first degree atrioventricular block among cardiac diseases group in order of frequency were: hypertensive heart disease (25.0%) arteriosclerotic heart disease (8.0%) and rheumatic valvular heart disease (5.0%). The most common etiology of those non-cardiac disease group was neuropsychiatry disorder (11.5%) and the next was infection (11.0%). 4. All of the complete atrioventricular block were associated with the cardiac disease, that is, 57.0% with arteriosclerotic heart disease, 28.5% with pericarditis and 14.3% with hypertensive heart disease, respectively. 5. The cardinal underlying disease of the incomplete right bundle branch block in order of frequency were: hypertensive heart disease (10.7%), arteriosclerotic heart disease (8.1%) among the cardiac disease group, and infections (15.4%) among the non-cardiac disease group. The incidence of healthy persons was 14.1%. 6. Those of complete right bundle branch block in order of frequency were: arteriosclerotic heart disease (13.2%), and hypertensive heart disease (10.1%) among the cardiac disease group, and infection(13.2%) and neurosis (10.1%), respectively among the non-cardiac disease group. 7. The major etiologies of the left bundle branch block was hypertensive heart disease and arteriosclerotic heart disease (33.3% each), and that of left posterior hemiblock was showed arteriosolerotic heart disease and cor-pulmonale. The most common etiological disease of the left anterior hemiblock was hypertensive heart disease in cardiac disease group, and infection and gatrointestinal disease in non-cariac disease group. 8. The abnormal electrocardiographic findings with the first degree atrioventricular block were left ventricular hypertrophy (24.8%), sinus tachycardia (11.0) and sinus bradycardia (5.8%). Those with the complete atrioventricular block were right ventricular hypertrophy (15.8%) and left bundle branch block (15.8%). In complete right bundle branch block, the majority (52.5%) showed single sign without other abnormality on E.C.G. In the left bundle branch block, there were 18.9% of left ventricular hypertrophy and 15.7% of first degree atrioventricular block. In the left anterior hemiblock, there were 28.5% of right bundle branch block, and 19.0% of right ventricular hypertrophy. In the left posterior hemiblock, there were 40.0% of atrial fibrillation and 20.0% of left atrial hypertrophy.

In this study we evaluated the risk factors that affect the survival rate of penetrating keratoplasty(PKP). Retrospectively we reviewed medical records of 275 cases which had taken PKP for 9 years between 1989 and 1997 in AMC. Mean age of patients was 39. 9 years and mean follow up period was 32.6 months. Only PKP was performed in 182 eyes(66%)and combined procedure with cataract extraction, silicon oil removal or glaucoma surgery in 93 eyes(34%). PKP was combined with cataract extraction and IOL insertion in 56 eyes. We analyzed the survival rate with Kaplan-Meier survival function. The survival rate was 94%for 3 months, 87%for 6 months, 78%for 1 year, 69%for 2 years, 62%for 5 years. According to the success rate based on etiology, keratoconus was highly successful in 82.6%and the survival rate of regraft or bullous keratopathy was significantly lower than that of keratoconus(p<0.01). Major cause of graft failure was rejection(68%)and rejection was occurred within 12 months following PKP in 65.2%. Rejection was reversed in 40.7%with medical treatment. So the factor that significantly affected the survival of graft was causative disease and this study suggested that the effort to prevent rejection was most important in graft survival.

BACKGROUND AND OBJECTIVES: Candesartan cilexetil (Atacand ), a selective type I angiotensin II receptor blocker, has recently been introduced as a new antihypertensive agent. We evaluated its anti-hypertensive effect and safety in mild to moderate hypertensive patients. MATERIALS AND METHODS: Candesartan cilexetil, 8 mg or 16 mg, was administered once a day over 8 weeks period in the patients with mild to moderate hypertension (25 male, 26 female, mean age: 53.5+/-1.2 years). For safety evaluation, laboratory tests were performed before and after treatment with candesartan cilexetil. Changes in blood pressure, heart rate and electrocardiogram were also observed. RESULTS: 1) The mean blood pressures in the sitting position were systolic 164.1+/-2.1 mmHg and diastolic 106.3+/-0.8 mmHg before treatment, which were lowered to 135.4+/-2.0 mmHg and 89.1+/-1.1 mmHg, repectively after 8 weeks of treatment (p<0.05). 2) Candesartan cilexetil had a significant dose-dependent antihypertensive effect for diastolic pressure in 35 patients (8 mg: 97.8+/-0.9 mmHg, 16 mg: 91.3+/-1.1 mmHg, p<0.05). 3) Heart rate was not significantly changed before and after treatment during the treatment with candesartan cilexetil (72.2+/-1.2/min vs. 72.0+/-1.3/min: p>0.05). 4) Laboratory tests revealed no significant abnormality by the treatment with candesartan cilexetil. 5) Left ventricular hypertrophy by ECG criteria detected in 3 cases disappeared after treatment with candesartan cilexetil. 6) No significant side effects were observed during the treatment period. CONCLUSION: Candesartan cilexetil, 8 mg or 16 mg, once a day is an effective and well tolerated antihypertensive treatment. It has a significant dose-dependent antihypertensive effect.

Through retrospective Jeju-cohort study at 2005, we found low rates of detection of osteoporosis (20.1%) and medication for osteoporosis (15.5%) in those who experienced hip fracture. This study was to determine the orthopedic surgeons' awareness could increase the osteoporosis treatment rate after a hip fracture and the patient barriers to osteoporosis management. We prospectively followed 208 patients older than 50 yr who were enrolled for hip fractures during 2007 in Jeju-cohort. Thirty four fractures in men and 174 in women were treated at the eight hospitals. During the study period, orthopedic surgeons who worked at these hospitals attended two education sessions and were provided with posters and brochures. Patients were interviewed 6 months after discharge using an evaluation questionnaire regarding their perceptions of barriers to osteoporosis treatment. The patients were followed for a minimum of one year. Ninety-four patients (45.2%) underwent detection of osteoporosis by dual energy x-ray absorptiometry and 67 (32.2%) were prescribed medication for osteoporosis at the time of discharge. According to the questionnaire, the most common barrier to treatment for osteoporosis after a hip fracture was patients reluctance. The detection and medication rate for osteoporosis after hip fracture increased twofold after orthopedic surgeons had attended the intervention program. Nevertheless, the osteoporosis treatment rate remains inadequate.

Bone cement augmentation procedures have been getting more position as a minimally invasive surgical option for osteoporotic spinal fractures. However, complications related to these procedures have been increasingly reported. We describe a case of bone cement dislodgement following cement augmentation procedure for osteoporotic spinal fracture by reviewing the patient's medical records, imaging results and related literatures. A 73-year-old woman suffering back and buttock pain following a fall from level ground was diagnosed as an osteoporotic fracture of the 11th thoracic spine. Percutaneous kyphoplasty was performed for this lesion. Six weeks later, the patient complained of a recurrence of back and buttock pain. Radiologic images revealed superior dislodgement of bone cement through the 11th thoracic superior endplate with destruction of the lower part of the 10th thoracic spine. Staged anterior and posterior fusion was performed. Two years postoperatively, the patient carries on with her daily living without any significant disability. Delayed bone cement dislodgement can occur as one of complications following bone cement augmentation procedure for osteoporotic spinal fracture. It might be related to the presence of intravertebral cleft, lack of interdigitation of bone cement with the surrounding trabeculae, and possible damage of endplate during ballooning procedure.

This prospective cohort study was performed to estimate the morbidity and mortality with 790 patients over 50-yr of age that sustained a femoral neck or intertrochanteric fracture from 2002 to 2006, followed-up for a mean of 6 yr (range, 4 to 9 yr). Crude and annual standardized mortality ratios (SMRs) were calculated; and mortalities in the cohort and the age and sex matched general population were compared. The risk factors on mortality and activities pre- and post-injury were assessed. Accumulated mortality was 16.7% (132 patients) at 1 yr, 45.8% (337 patients) at 5 yr, and 60% (372 patients) at 8 yr. SMR at 5 yr post-injury was 1.3 times that of the general population. Multivariate analysis demonstrated that age (OR, 1.074; 95% CI, 1.050-1.097; P<0.001), woman (OR, 1.893; 95% CI, 1.207-2.968; P=0.005), and medical comorbidity (OR, 1.334; 95% CI, 1.167-1.524 P<0.001) were independently associated with mortality after hip fracture. Only 59 of the 150 patients (39.3%) who were able to ambulate normally outdoors at preinjury retained this ability at final follow-up. Patients with a hip fracture exhibits higher mortality at up to 5 yr than general population. Age and a preinjury comorbidity are associated with mortality.
