Bronchiectasis means a permanent abnormal dilatation of one or more large bronchi owing to destruction of theelastic and muscular components of the bronchial wall. Radiological study is the most importat and mandatory procedure. Especially bronchography is essential for the definitive diagnosis of bronchiectasis and for theprecise delineation of the type and extent of the disease. The radiological and clinical findings of 48 cases ofbronchiectasis diagnosed by bronchography and treated at Chosun University Hospital during the 5 years fromJanuary 1980 to Dec. 1984 were analyzed retrospectively. The results were as follows; 1. Among the 48 cases, 34cases(70.8%) were male and 14 cases(29.2%) were female. Peak incidence was in second decade. 2. Chronic cough,productive sputum and hemoptysis are main symptoms and others are chest pain, dyspnea and recurrent bouts ofpneumonia. The most common physical sign is persistent moist rales over the involved area in 23 cases(47.9%).Others are no sign in 17 cases(35.4%), wheezing in 11 cases(22.9%) and digit clubbing in 3 cases(6.3%). 3. Thepresumed causes were composed of not known in 30 cases(62.5%) and complications of measles in 7 cases(14.6%),pertusis in 5 cases(10.4%) and pneumonia in 4 cases(8.3%). Two cases were Kartagener's syndrom and unilateralhyperlucent lung. 4. Plain chest roentgenographic findings were abnormal in 42 cases(87.5%) but normal in 6cases(12.5%). The most common radiological findings was accentuation of lung markings in 36 cases(85.7%) theothers are include in order of frequency; pneumonic infiltration, linear radiolucencies, cystic radiolucencies,decreased affected lung volume air-fluid level and pleural thickening. 5. Bilateral bronchiectasis was demonstrated in 11 cases(22.9%) and the disease was much more often involved left lung than right. The mostcommonly involved lobe is left lower lobe, and the most common site of involvement was the posterior basal segmentof the lower lobe. The type of bronchiectasis is cylindrical in 22 cases(45.8%), varicose in 11 cases(22.9%),saccular in 9 cases(18.8%) and mixed type in 6 cases(12.5%)

Two types of urine dipstick assays, Multistix-SG and Comber-9-Test RL, were compared for compatibility, accuracy, specificity and predictive values of a positive and negative test in 501 patients' urine and artificially prepared specimen. We found that the results of semiquantitative tests of Multistix-SG and Comber-9-Test RL performed were statistically similar in patients' specimen. The urinary leukocyte esterase tests of Comber-9-Test RL assays compared with urine sediment microscopy in regard to compatibility, sensitivity, specificity, and predictive values of a positive and negative test 83.7%, 48.1%, 90.3%, 47.4% and 90.1%, respectively. The urinary nitrite tests of Comber-9-Test RL assays compared with urine culture tests, in regard to compatibility, sensitivity, specificity, and predictive values of a positive and negative test were 90.3%, 19.4%, 84.7%, 53.8% and 94.1, respectively. For the urinary protein, the sulfosalicylic acid method was the most sensitive test for any kinds of protein, and Multistix-SG appeared more sensitive than Comber-9-Test RL for the albuminuria. For the urinary bilirubin and glucose, two dipstick assays were similar in their diagnostic efficiency. Finally in the urinary occult blood tests, Comber-9-Test RL assays was more sensitive than Multistix-SG.

We investigated mean keratometric vale(K) after penetrating keratoplasty(PKP) and analyzed the factors which affected the postoperative mean K. We obtained mean K at postoperative 3 months in the 65 eyes of 65 patients which PKP of PKP combined with intraocular lens(IOL) implantation was done, and analyzed those values according to sex, age, preoperative diagnosis, preoperative corneal neovascularization, methods of trephination, methods of suture and methods of operation. The postoperative mean K of all patients was 42.83 diopters(D) and 43.32D in the recipient cornea without neovascularizaion, 42.51D with neovascularization, 42.72D in the cases of hand-held trephination and 43.27D in Hessvurg-Varron trephination, which had no statistical significant difference between K and sex, age, preoperative diagnosis, methods of suture, and methods of operation. This results will be helpful to predict the change of K ofter PKP, and give a better refractive results to use the operator's own mean K for the IOL calculation in the case of PKP comvined with IOL implantation.

It is well known that general anesthesia and surgery cause acute depression of renal function. Also, the occurrence of frank bleeding from the urinary tract can form a blood clot which may block an indwelling catheter or even a normal urethra with development of urinary infection. Many studies have reported that prophylactic use of hypertonic mannitol will prevent acute functional renal impairement during general anesthesia and surgery, and reduce the incidence of clot formation and acute pyelonephritis. We believe that diuresis itself is a reneprotective mechanism and polyuria may yield two other advantages; 1. Fewer plugged catheters by decreasing the incidence of clots. 2. Decreased incidence of acute pyelonephritis by preventing stasis and washing out bacteria. since 1972, in our hospital, 100cc or 200cc of 20% mannitol was used for increasing the urine output during operation of urinary stone in 33 patients, We have shown that the prognosis of patients was good.

Endothelial cell have been shown to play an active role in many phases of immunologic process, including binding of T lymphocytes, neutrophils, platelets, and monocytes to the endothelium, as well as phagocytosis. Endothelial cells can also serve as targets that undergo cell injury. The most prominent mediators of endothelial cell activation are IL-1beta and TNF-alpha. VLA-4 was first identified as an endothelial cell surface receptor. We performed the culture of endothelial cells derived from human glomerular capillaries and studied the cytokine-regulated expression of VCAM-1, and the effect of dexamethasone and TGF-beta on the cytokine induced VCAM-1 expression using ELISA method. Expression of VCAM-1 was not detectable above background level in the basal unstimulated state. However, VCAM-1 was rapidly induced after exposure to IL-1beta (5ng/ml) or TNF-alpha (1, 10ng/ml) (O.D.=1.76+/-0.15, 1.95+/-0.35, 1.88+/-0.17, mean+/-S.E., control=0.36+/-0.028, n=8-24, P<0.05). But IFN-gamma did not increase the expression of VCAM-1. Addition of dexamethasone (10 micrometer) and TGF-beta1 (1ng, 10ng/ml) blunted IL-1beta and TNF-alpha induced expression of VCAM-1. Therefore, VCAM-1 could be inducible in human glomerular endothelial cells, and it was regulated by dexamethasone and TGF-beta1. The negative findings in histopathology may reflect the transience of VCAM-1 expression and does not necessarily exclude an important role of this molecule in the early stages of renal disease.
