The study was undertaken to determine the cardiovascular response to spinal cord trauma and to determine the autonomic mechanisms involved. The arterial pressure was recorded in anesthetized cats during spinal cord trauma of 50gm-cm at T4-T6 levels. The spinal cord trauma resulted in a sudden increase of systemic blood pressure from a control level of 92mmHg to 140mmHg, an increase of 52%, at 45 seconds. This initial hypertensive plase lasted approximately 3 to 4 minutes, and then was followed by a hypotensive phase. 2) This pressor response was mediated by an beta-adrenergic blocking agent. 3) During the hypertensive phase, the pulse pressure was increased while the heart rate was decreased, The pulse pressure and the heart rate changed symmetrically, showing the maximal elevation and minimal decrease at 20 seconds, respectively. These results suggest that the alternations in blood pressure that follow the spinal cord trauma are most likely related to alternations of peripheral arteriolar resistance and venous return of blood to the heart.

Iron deficient state occurs commonly in the athlets, and the cause may be inadequate iron intake, loss of iron from sweat, blood loss of gastrointestinal tract, and hematuria. The age of the athletes ranged from 11 to 17 years old. I messured red blood cell count, hemoglobin, hematocrit, and related hematologic factors in the 32 adolescent female athletes and 21 female controls. a hematologic comparison was perfomed between the athletes and controls. The results obtained were as follows: 1) A value of hemoglobin were 11.6+/-1.4g/dl in the athletes and 12:4+/-0.8g/dl in controls (p<0.05). 2) Hematocrits were 34.1+/-3.4% in the athletes and 37.4+/-2.3% in controls (p<0.05). 3)A value of red bolld cell distribution width values were 13.9+/-2.1% in the athletes and 12.2+/-1.1% in controls (p<0.05). 4) Serum iron was 87.7+/-30.3ug/dl in the athletes and 121.8+/-39.0ug/dl in controls (p<0.001). 5) Total iron binding capacity was 445:6+/-31.8ug/dl in the athletes and 384:6+/-54.2ug/dl in controls (p<0.001). 6) Mean transferrin saturation values were 19.7+/-6.9% in the athletes and 32.5+/-10.8% in control (p<0.001). 7) Ferritin was 14.5+/-10.0ng/ml in the athletes and 33.9+/-13.9ng/ml in controls (p<0.001). 8) The duration of exercise was 4.8+/-2.5 years in the stage III iron deficiency, whil 3.0+/-2.0 years in normal group in iron deficient state (p<0.05).

A study was made of 104cases of neonatal hyperbiliruinemia receiving blood exchange transfusion at Kwangju Christian Hospital from January 1969 to December 1975, with the following results: 1. 52 patients(50%) returned for follow-up, 9 patients(8.7%) had died, and 43 patients(41.3%) did not return. 2. Of the 52 patients returning, developmental status was studied by D.D.S.T. 43 patients(82.7%) had normal development, 8(15.4%) were retarded, and 1(1.9%) was questionable. No patients had a failing score. Most of the retarded patients had cerebral palsy, due to kernicterus. 3. There was no retardation among patients exchange-transfused at age of less than 5days, or over 8 days(except 1 pts.) , and with less than 30mg% of Pre-B.E.T. serum bilirubin level. 4. No significant difference of sex incidence was noted. 5. ABO incompatibility (57%) was predominant as the etiology and main cause of retarded development (19.4%), but the idiopathic type of hyperbilirubinemia(41.3%) was interestingly high among these B.E.T. patients. 6. Mean value and standard error of pre-B.E.T. serum bilirubin levels are as follows: Normal development group:30.80+/-1.60 Retarded development group:38.83+/-2.35 The difference of men values between both groups is very significant according to the t-test. 7. Motor disturbance was the predominant handicap in retarded patients at ages less than 3 years, and after this there was a tendency toward recovery, accompanied by mild speech disturbance. Hearing loss, especially of high pitched tone, was noted in 1 patient and confirmed by audiometry.

Almost always patients with multiple neurofibromatosis show cafe-au-lait macules on their skin. At times the skin macules are seen even before the appearance of the neurofibromata in childhood. The author experienced one case of neurofibromatosis in a 12-year-old boy who has no cafe-au-lait macules. Besides the clinical peculiarity of having no skin pigmentation, the histopathology of the case showed well-formed double-palisading structure, which is not common among the micro-scopical findings of neurofibromata.

A 41-year-old female was admitted to our hospital for self-audible wheezing sound and dyspnea. On past history, she has been suffered from chest discomfort, and treated recurrently by other hospitals. But, there was no symptomatic improvement. A stridor and mixed wheezing sound was auscultated on whole lung field. PFT revealed fixed type or variable intra- & extra-thoracic air way obstructive pattern. By bronchoscopy & bronchogram, we found web-like structure on the distal trachea. A bronchoplasty was performed and the post-operative PFT showed slight improvement & she had no more complaints.

Rotator cuff tears are a common cause of debilitating pain, reduced shoulder function, and weakness. Despite improvements in the understanding of the disease process and advances in surgical treatment, recent studies have reported that healing of massive rotator cuff tears is not as predictable as that of smaller rotator cuff tears. These high failure rates are a result of both mechanical and biologic factors that may affect the patients' intrinsic capacity to heal. Most research studies have concentrated on tissue engineering as a means for improvement of healing in rotator cuff repair, including the use of scaffolds, growth factors, and mesenchymal stem cells. There has been much interest in the development of various scaffolds that provide adequate strength as well as stimulate and enhance healing potential. The purpose of this paper is to review the current basic science and clinical application of extracellular matrix scaffolds, which are currently the most widely used scaffolds for repair of rotator cuff tears.

BACKGROUND AND OBJECTIVES: Many authors(Simmons,1973, McGath et al.,1989) described that a small percentage(1-2 %) of patients initially complaining of vertigo was found to have bilateral vestibular failure (BLVF). This study evaluates the findings of vestibular function test (VFT) including rotating chair test (ROT) and computerized dynamic posturography test (CDP) in the patients with BLVF demonstrated by caloric test and others. Method : 400 vertigo patients were given VFT from June,1994 to October,1995. In the patients who had absent or reduced responses (total eye speed <10 degrees per second) in cold (17 C) water caloric testing or decreased responses in the range of lower fequencies during ROT, we evaluated their VFT results and clinical features. RESULTS: There were 38 cases out of total 400 patients(9.5%). Many patients with BLVF had rotational response magnitudes (at 0.04 Hz and above) that were within normal limits. CBP has shown vestibular dysfunction patterns in 32 patients. Hearing tests were normal in 9 cases and mixed hearing loss in 2 cases. Many patients experienced several episodes of acute vertigo with persistent imbalance; Only 4 patients complained of persistent oscillopsia. Viral infection (vestibuloneuronitis), immune reactions and toxic factors may play a role in the etiology of this rare BLVF. CONCLUSION: Our incidence of 9.5% is much higher than what was reported in the literature. Herb medications and frequent injections of aminoglycosides may be responsible for this higher incidence of BLVF. ROT is useful in detecting and predicting the remaining vestibular function in the BLVF patients.
