During the past 10 years 114 patients with empyema have been treated in hospital of Chonnam University. There were 87 males and 27 females ranging from 20 days to 70 years of age. The etiology was pyogenic pneumonia in 36.7%, tuberculosis in 22.7%, paragonimiasis in 8.8%, post-thoracotomy in 5.4%, post-trauma in 4.4%, lung abscess in 3.5%, malignancy in 3.5%, post-esophageal operation in 1.8%, and sterile in 10.5%. The over-all mortality rate was 2% [3 patients]. The majority of deaths occurred in patients with associated systemic illness [liver cirrhosis in I, and renal tuberculosis in I] and resistant tuberculosis for anti-tuberculosis drugs in one patient. Adequate drainage and obliteration of the pleural space continues to be the most important aspect of treatment and can frequently be achieved by closed chest tube thoracostomy in acute empyema especially in children. The more chronic thick-walled or loculated cavities require open drainage [open window therapy], decortication, thoracoplasty, sterilization, and myoplasty for closure of tracheobronchial fistula.

We report an unusual case of delayed bleeding after open surgical repair of a thoracoabdominal aortic aneurysm. A 79-year-old man developed a massive retroperitoneal hematoma 49 days after Crawford type III thoracoabdominal aorta replacement. During emergency surgery, a tear was found in the prosthetic vascular graft caused by a sharp bony spur arising from the second lumbar vertebral body. This rare, but potentially lethal, complication indicates that attention should be paid to sharp bony structures during open repair of the descending aorta.

시식성 파리에 의한 폐가축의 분해촉진 가능성을 폐사돈과 폐계를 사용하여 실험하였다. 2007년 5월 30일에 야외에 방치한 폐사돈(36kg)은 23일 후에 완전히 분해되었다. 2007년 7월 25일 폐계(3.4kg)를 상자에 넣고 문을 닫아두었을 때보다는 열어 놓았을 때에 야외의 파리가 유인되어 산란함으로써 더 빨리 분해되었다. 폐계를 상자에 방치한 지 6일 후의 무게는, 문을 3일간 열어두었을 때에는 0.6kg으로 감소하였으나 문을 닫아두었을 때에는 3.0kg으로 분해 속도가 느렸다. 2007년 10월 1일 폐계를 상자에 넣고 구리금파리(Lucilia sericata)를 50쌍 접종하였을 경우에는 3.2kg이던 것이 접종 22일 후에 1.0kg으로 줄어들었으나, 암:수 200:100 마리를 접종하였을 때에는 3.4kg이던 폐계가 11일 후에 0.8kg으로 감소되었다. 따라서 폐가축은 파리류에 의해서 분해가 촉진될 수 있으며, 폐가축 분해를 위한 검정파리류의 실용화를 위해서는 더 다양한 크기의 폐가축을 대상으로 더욱 다양한 환경조건 하에서 분해속도를 조사해야 할 것으로 생각된다.

Twenty four early lactating Nili-Ravi buffaloes, eight in each group, were used in a Randomized Complete Block Design to evaluate the influence of varying ruminally degradable protein (RDP) to ruminally undegradable protein (RUP) ratio on feed intake, digestibility, N balance, milk yield and its composition, conception rate and days open. Three experimental diets were formulated to contain RDP:RUP of 50:50, 66:34 and 82:18 and were denoted as HRUP, MRUP and LRUP, respectively. Dry matter (DM) intake was higher (p<0.05) in buffaloes fed HRUP diet than in those fed MRUP and LRUP diets. Dry matter digestibility was higher (p<0.05) in buffaloes fed LRUP diet than in those fed HRUP and MRUP diets. Linear increase was observed in DM digestibility with increasing RDP:RUP while Neutral detergent fiber digestibility remained unaltered in buffaloes fed HRUP and MRUP diets, however, it was higher than in those fed LRUP diet. Crude protein digestibility remained unaltered across all treatments. Milk and 4 percent fat corrected milk (4% FCM) yield was higher (p<0.05) in buffaloes fed HRUP diet than those fed MRUP and LRUP diets. Linear decrease in milk yield was observed with increased RDP:RUP. Milk protein and fat yields were higher (p<0.05) in animals fed HRUP diet than those fed MRUP and LRUP diets. Milk protein percent in animals fed HRUP diet was higher than in those fed LRUP diet, whereas it did not differ with those fed MRUP diet. Percent of fat, total solids, solid not fat and lactose remained unaltered across all diets. Nitrogen balance was higher in buffaloes fed HRUP diet than in those fed other diets. Increasing the RDP:RUP resulted in a linear decrease in N balance. The blood urea nitrogen and milk urea nitrogen were lower (p<0.05) in buffaloes fed HRUP diet than those fed MRUP and LRUP diets. The blood pH remained unaltered across all treatments. Days open did not differ significantly. Conception rate was higher in buffaloes fed HRUP diet than those fed MRUP and LRUP diets. The findings of the present study indicate that feeding high (50% of the total crude protein) ruminally undegradable protein diet not only increased nutrient intake and milk yield but also improved conception rate in early lactating buffaloes.

To define the amount of consumptive use of upland crops, the moisture consumption characters were investigated with different soil moisture content by soil properties(loam, sandy loam, sand) at the experimental farm of Kon-Kuk University from April 20 to July 20 1984. The results obtained are summarized as follows; 1. Total moisture consumption under bare soil condition had an order of loam> sandy loam> sand and showed an order of pF 1.5> pF2. 1> pF 2.7 by re-irrigation point and the average during the experimental period (92days) was 435. 9mm and the daily average moisture consumption was 4. 7mm. 2. The moisture consumption characters of bare soil plot obtained showed that the amount of irrigation water per one time and the days of intermission increased and, on the contrary, the times of irrigation and the total amount of irrigation water decreased by the increment of re-irrigation point in the same soil 3. Total moisture consumption of spring cabbage under open cultivation showed 528.6 rim in maximum and had an order of loam> sandy loam> sand. In the aspect of rc-irrigation point, it had an order of pFl. 5> pF 2.1> pF 2.7. In case the planning basic year was taken into account, the amount of irrigation water needed for open cultivation was 456. 3 mm and its average daily moisture consumption was 6. 2mm. 4. Total moisture consumption of summer cucumber under open cultivation showed 635. 8mm in maximum and had an order of loam> sandy loam> sand. In the aspect of re-irrigation point, it had an order of pF 1.5> pF2. 1> pF2. 7 In case the planning basic year was taken into consideration, the amount of irrigation water was 516. 9mm and its aversge daily moisture consumption was 6. 5mm. 5. The result of cabbage cultivation showed its maximum yield in loam soil when the pF values were maintained from 1,5 to 2.1 and then the evapotranspiration ratio was 1, 76 and also when the amount of irrigation water were similar, it showed effective to reduce the days of intermtission. 6. The result of cucumber cultivation showed its maximum yield in sandy loam soil when the pF value maintained from 1.5 to 1.7 and when the irrigation point maintained at pF 2,7 in sandy soil, its yield was severely decreased.

This study assessed the incidence of embryo and fetal loss following early pregnancy diagnosis using ultrasonography in dairy cows. A positive pregnancy was a recognition of the vesicle, embryo or fetus by ultrasonography. Seven hundreds and two pregnancies determined by ultrasonography following artificial insemination were divided into three groups according to the number of days diagnosed pregnant: early A group (27 to 40 days, n = 143), early B group (41 to 50 days, n = 172), or standard group (51 to 70 days, n = 387). Following a positive pregnancy diagnosis, embryo or fetal loss included all cows with observed abortions and cows found open after the positive pregnancy diagnosis. The incidence rate of embryo or fetal loss within 7 days after pregnancy diagnosis was 1.4, 0.6 and 0.3% for the early A, early B, and standard groups, respectively (P>0.05). The incidence of the embryo or fetal loss during 8 to 30 days after pregnancy diagnosis did not differ (P>0.05) among the early A (0%), early B (1.2%), and standard groups (1.0%). Furthermore, the cumulative incidence of the embryo or fetal loss before calving did not differ (P>0.05) among the early A (9.8%), early B (9.3%), and standard groups (5.9%). These results indicate that early pregnancy diagnosis using ultrasonography does not increase the risk of embryo and fetal loss compared with that of routine pregnancy diagnosis in dairy cows.

This study was conducted to establish a colostomy technique using cannulation in white Leghorn male chicks. A everted rectum method was used for colostomy from 3 to 20 months old roosters. After 2 or 3 days of operation, blood clots were taken off. At this time, a cannula was also inserted into artificisal annus to keep it open. The cannula was regularly exchanged at every 7 to 10 days. Polyethylene bag and plastic beaker were used for feces and urine collection, respect-ively. The present paper describes the methods of operation, cannulation after colostomy recturn and post-operation management. This method has succeeded in colostomising chickens that survive as long as their normal counterparts.

During the period from February to March, 1984, we employed a partial left heart bypass [left atrium to ascending aorta] in 2 patients who could not weaned from cardiopulmonary bypass with inotropic agents and cardiac pacing after coronary bypass surgery. These two patients showed significant improvement in ventricular function 18 to 47 hours after inserting the left heart bypass and were able to wean from the left heart bypass under using inotropic agents. Two patients died of multiple organ failures 11 days and 15 days postoperatively. These results indicate that early institution of left heart bypass in ventricular failure patients after open heart surgery can provide satisfactory long-term result.

Phrenic nerve injury has been reported with the use of iced slush for topical cardiac hypothermia. A review of the preoperative and the postoperative chest roentgenograms was performed to detect phrenic nerve injury in patients undergoing cardiac operation with the use of iced slush for topical hypothermia from January, 1985 to June, 1987. The reviewed series included 45 patients who had undergone valve replacement. In this review, the injured site of phrenic nerve was left in 13 cases, right in 1 case and the overall incidence of phrenic nerve paralysis following open heart surgery was 31%. Compared to the incidence of phrenic nerve paralysis in the control group [without pericardial insulation] [406, 12 cases/30 cases], that in the group of patients receiving pericardial insulation [13.3%, 2 cases/15 cases] was lower, but there was no statistical significance. The initial time that diaphragmatic paralysis developed was mean 3.5 days [range 1-8 days] postoperatively and the recovery time of the paralysis was mean 4.7 months [range 0.5-10.5 months] postoperatively.

Seven infants less than age 3 months underwent patch aortoplasty and tube graft bypass for relief of coarctation of aorta. All had intractable congestive heart failure, despite aggressive medical therapy Each infant had other cardiac anomalies including patent ductus arteriosus, ventricular septal defect, atrial septal defect and congenital mitral stenosis. All patients underwent closure of the ductus arteriosus and patch angioplasty of the aorta to produce a luminal diameter of at least 15mm or tube graft interposition utilizing the Gortex tube graft diameter larger than 10mm. In 5 patients who had ventricular defect, they underwent pulmonary arterial banding. &ere was one hospital death 17 days after operation secondary to the hydronephrosis and renal failure. Hospitalization was less than 10 days after operation except one case. In 3 patients who had associated VSD, open heart surgery[VSD closure+PA debanding]was done without difficulty. Surgical repair of critical coarctation of the aorta in infants can safely be offered despite the poor preoperative condition and presence of other cardiac anomalies.
