AbstractAbstract PDF
Soft-tissue expansion is a new surgical technique of providing donor tissue in modern reconstructive surgery. This technique provides a quantity of tissue of similar color, texture, and hair-bearing qualities for reconstruction of adjacent defects. It is known that the expanded skin shows several constant histologic changes including the increase in collagen fibers and vascularity within dermis, and thinning of subcutaneous tissue and dermis. In this study, the author observed serial histologic changes of rabbit skin induced by progressive tissue expansion up to excessive expansion of 6 times. The results are as follows: 1. Changes in the thickness of the epidermis was minimal until 3 times of expansion, but slight thinning was observed at excessive expansion state. 2. The thickness of the dermis was progressively decreased, and collagen fibers in the dermis was rapidly increased in early phase of expansion. 3. The vascularity in the dermis was also progressively increased. 4. The skin appendages showed no structural changes even in excessive expansion. 5. The panniculus carnosus showed no atrophic changes and the thickness was maintained in excessive expansion.

AbstractAbstract PDF
Phosphoinositide-specific Phospholipase C (PI-PLC) is a second messenger of signal transducer on cell membrane. In the previous study, PLC of bovine brain has been purified three isozymes. In this paper, uterus and seminal vesicle have been purified. Two peaks of PI-PLC activity were resolved when bovine uterus and seminal vesicle proteins were chromatographed on a DEAE and phenyl TSK 5PW HPLC column. Each two peak was compared with PI-PLC I, II and III from bovine brain and we got the retention time on HPLC. The peak fractions with PLC activity were tested homogeneity with brain PLC monoclonal antibodies (Mab). Mab-labeled affigels were bounded in the range of 73.8%~97.5% with PLC I, II and III. Homogeneity of fractions were revealed that DEAE F-1 and phenyl F-1-I were highest level of PLC III in uterus and seminal vesicle and DEAE F-2 and phenyl F-2-I were mixed PLC I and II.

AbstractAbstract PDF
The intradermal (ID) test has been widely used in Korea and several reports about the results of the ID test are known. We examined the egg of Clonorchis sinensis (C.s.) by ID test in 443, stool's egg-counting technique in 79 and direct smear (cellophane thick smear technique) in 1204 subjects. The results are as follows: 1. The positive rate of C.s. was 3.8% out of 1304 persons. 2. The sensitivity of ID test was 82.1% out of 39 persons and the specificity was 64.6% out of 404 persons. 3. The false positive of ID test was 35.4% out of 404 persons and, the false negative was 17.9% out of 39 persons. Intradermal test is a rapid, sensitive and useful supplementary diagnostic tool for the detection of Clonorchiasis infection and must be used as screening test with direct smear of stool but cross reaction with other helminth infections and moderate false reaction are the main disadvantages in its practical application.

AbstractAbstract PDF
KOH examination is a simple, rapid and diagnostic procedure to confirm dermatophytic infections. It is important to select a proper examination site of the lesion. To determinate the proper examination site of the lesion, mycologic studies were done with multiple specimens collected from the center, margin and out of margin of the ring-shaped dermatophytic skin lesion on the 58 patients. The results were as follows. Positive rate of KOH wet smear was 94.8% at the center and 100% at the margin of the lesions, 22.4% at the 1 cm and 5.2% at the 2 cm out of the lesions. The more hyphae were found in the lesion, the more hyphae were found out of the lesion. Culture was done on the Sabouraud's glucose agar from the highest KOH positive area and the positive culture was 48 strains (82.8%) of 58 patients. These findings suggested that the ring-shaped active margin was the best site to examine mycologic studies.

AbstractAbstract PDF
This study was designed to investigate the effect of substitution of strontium for calcium on mechanical activity in isolated perfused spontaneously beating rat hearts. The mechanical activity of the hearts of Langendorff's preparation in conditions of low calcium and strontium-substitution for calcium was compared. The effect of norepinephrine and verapamil were also observed in those conditions. The results were as follows: 1. In low calcium, the mechanical activity of the heart preparation was significantly reduced, but when the equimolar strontium was substituted for the reduced calcium, the activity was kept at similar level to the normal condition. 2. When equimolar strontium was substituted for the total calcium in perfusate, the heart preparation stopped its beating, and it was not restored in spite of reperfusion with normal calcium perfusate. 3. Norepinephrine-induced positive inotropic effect was inhibited in low-calcium condition especially with low concentration of norepinephrine, but not in strontium-substitution for calcium. 4. Verapamil reduced the activity of the heart both in low-calcium and strontium-substitution as well as in normal calcium conditions. From above results, it was concluded that strontium served as a substitute of calcium in maintaining mechanical activity and in responsiveness to norepinephrine, and the influx of strontium through cell membrane is inhibited by verapamil as the influx of calcium.

AbstractAbstract PDF
In the present study the effect of exercise on the conversion rate of ingested glucose to glycogen in the different types of hindlimb skeletal muscles in Sprague-Dawley male rats was studied. The amounts of synthetized glycogen from ingested glucose of fast-twitch white (WV), fast-twitch red (RV), mixed type of fast-twitch white and red (EDL), and slow-twitch (SOL) muscles were determined at 30 and 90 min. after ingestion of 25% glucose solution which contained 14C-glucose(2 ml(luCi)/100gm B.W.) in control and exercise loaded rats. The result was summarized as follows: The about 55% at 30 min. and 70% at 90 min. after glucose ingestion were absorbed from gastrointestinal tract. This result shows no effects of exercise on absorption rate from gastrointestinal tract. The amount of synthetized glycogen of SOL from ingested glucose at 30 and 90 min. after glucose ingestion were highest, whether WV were lowest in hindlimb skeletal muscles in control and exercise loaded rats. In the exercise loaded rats, the amounts of synthetized glycogen of SOL, RV, and EDL at 90 min. after glucose ingestion was much higher than control rats, but not different in WV between exercise-loaded and control rats. At 30 min. after glucose ingestion, only SOL of exercise loaded rats was higher than control rats. In the control rat, the synthesis of glycogen was almost completed during initial 30 minutes. On the other hand, in the exercise loaded rat, except WV was opposite result of control rats, i.e., amounts of synthetized glycogen were major during late period. The amount of synthetized glycogen of liver at 30 and 90 min. after glucose ingestion in exercise loaded rats was higher than control rats. The rate of glycogen synthesis in control and exercise loaded rats were higher between 30-90 minute than initial 30 minutes.

AbstractAbstract PDF
The diagnosis of OPCA could be made clinically with important aid of brain CT scanning, although the definite and conclusive diagnosis only by postmortem pathological determination. We reviewed, clinically and with brain CT examination, 12 cases of patients with OPCA who were admitted to the Yeungnam University Hospital for a recent 5 years. The result were as following: 1. The distribution of age is from 49 to 72, mainly 50 to 60. Man is more frequent than women at the 4.5 times. 2. The interval period from Sx. Onset to diagnosis is 1 year to 6 years. 3. The usual initial Sxs. Were dizziness (58%), ataxia (33%), and other less frequent Sxs. Were weakness of low extremities, dysarthria, headache and urinary incontinence. The clinical manifestations at the initial diagnosis were cerebellar disturbance (100%), dysarthria (83%), and increased deep tendon reflexes (58%). 4. The results of brain CT finding are like this: the width of cerebellar sulci is more than 1mm, other 4 cases more than 2mm. the width of cerebellar pontine cistern of the patient if usually 3 to 4mm, other 2 cases extended to the 5 mm. the A. P and lateral lengths of 4th. ventricle is 4 mm and 4 to 8 mm respectively. 6 cases of whole patients show coincidentally cerebral atrophy.

AbstractAbstract PDF
Ipratropium bromide (IP) is a new anticholinergic bronchodilator. To evaluate its effect on bronchial asthma which is still unknown in Korea, a double blind and randomized study was done on all patients of bronchial asthma who visit out-patients clinic of out department from June to September 197 and showed 75 to 100% of FEV1/FVC ratio on prebronchodilator spirometry (pre BD). The selected patients were given 2 puffs of Fenoterol (FE) or Ipratropium inhalator blindly and Spirometry. The repeated results are: 1. In both FE and IP groups, there was a significant bronchodilatory effect on 5 and 60 minutes after administration. 2. One 5 minutes, effect of FE was significantly greater than IP (FVC p<0.05, FEV1 p<0.01). 3. One 60 minutes, effect of IP was slightly less than FE but statistically non-significant. On the basis of above results, we concluded that onset of effect of IP is slower than FE, but its effect is significant and nearly comparable to FE.

AbstractAbstract PDF
Between April, 1984 and September 1988, 459 patients underwent cardiovascular surgery at the Yeungnam University Hospital. Of these, 355 cases were open heart surgeries and 104 cases were non-open heart surgeries. There were 237 patients of acyanotic congenital cardiac anomalies, 40 patients of cyanotic congenital cardiac anomalies, and 85 patients of acquired heart diseases. The sex ratio of cardiovascular diseases was represented as 1:1.3 in male and female. The age distribution was ranged from 1 day to 65 years old. The common congenital cardiovascular anomalies were ventricular septal defect (38.7%), patent ductus arteriosus (25.5%), atrial septal defect (20.7%), Tetralogy of Fallot (8.3%), and pulmonary stenosis (2.4%) in order of frequency. Among 87 acquired cardiovascular diseases, 81 patients underwent operation for cardiac valvular lesions, 51 patients had mitral valve replacement and 13 patients had aortic valve replacement and 17 patients had double valve replacement. The overall mortality of cardiovascular surgery was 3.3% and mortality of open heart surgery was 3.9%.

AbstractAbstract PDF
To elucidate the effects of dimethyl sulfoxide on of myocardial and endothelial cells in culture, the cells were exposed to 10% dimethyl sulfoxide in culture medium for 1 hour at 48 hours after cell isolation. The general morphology and the cytochemical reaction of marker enzymes for mitochondria and Golgi complexes were investigated. The results were summarized as follows 1. DMSO induced elongation and narrowing of the cells and increase of mitochondrial reaction in myocardial cells. 2. DMSO induced destruction and disruption of myofibrils in myocardial cells resulting in increase of contractile activities. 3. In the endothelial cells, DMSO suppressed proliferative activities but thiamine pyrophosphatase reactions were enhanced indicating increase of Golgi complex activity. 4. DMSO seemed to hamper with the adhesiveness and motility of the endothelial cells causing the decrease of the number of cells in vitro.
