Neonatal Sepsis is a frequent and important cause of morbidity and mortality in the neonatal period. This study was undertaken to observe the 55 cases of proven neonatal sepsis among 6,717 newborn infants under 4 weeks of age, admitted to the nursery of Yeungnam University Hospital from May 1, 1983 to April 30, 1988. We observed following results: 1. The morbidity rate of male (1.12%) was higher than that of female (0.44%) significantly (p<0.05). 2. The morbidity rate of prematurity (2.65%) was higher than that of full term (0.76%) significantly (p<0.05). 3. The incidence of perinatal obstetric complications in early onset neonatal sepsis was higher than that of late onset neonatal sepsis (38.5% vs 10.3%, p<0.05). 4. The common clinical manifestations were poor feeding (52.7%), jaundice (45.5%), diarrhea (30.9%) and irritability (30.9%). 5. Among the causative organism, gram positive organisms were predominated and Staphylococcus epidermidis was the most common organism. There was no difference in the causative organisms between early onset and late onset sepsis.

PURPOSE: To investigate audiometery and characteristics related to tinnitus in tinnitus patients. and to understand the relationship between the discomfort of tinnitus and the quality of life. Methods: The subjects were 110 patients with tinnitus. The data were collected using tinnitus handicap questionnaire. quality of life, and pure tone audiometry, which measured hearing level in dB and frequency in Hz matching of tinnitus. RESULTS: Majority of tinnitus patients (75.5%~81.8%) had normal auditory sensation. but 82.7% of patients indicated that they have heard tinnitus frequently. or always, and the major sounds of tinnitus were wing, wung, wang, The matching sounds of tinnitus had various range in hearing level(dB) and frequency(Hz). Tinnitus patients reported moderate levels of the discomfort of tinnitus and the quality of life, and there were negative correlation between the discomfort of tinnitus and the quality of life(r=-.314, p .00l). CONCLUSION: These findings suggest that special attention is needed for tinnitus patients because the physical. psychological. and social impacts of tinnitus could be decrease their quality of life, Specialized nursing intervention considering specific conditions related to tinnitus is required to solve various health problems of tinnitus patients.

The CRST syndrome, first reported by Winterbauer, represents a benign variant of scleroderma and consists of calcinosis(C), Raynauds phenomenon(R), sclerodactyly(S) and telangiectasia(T). The authors report a case of CRST syndrome confirmed by both clinical and histopathological findings. A 62-year-old female developed subcutaneous nodules on both elbow and knee joints, Raynauds phenomenon, sclerodactyly with acrosclerosis and scleroderrnatous changes on both hands and forearms and telangiectasia on the face, neck, and hands of 15 years duration, but she had no difficulty in swallowing. The authors treated a case of CRST syndrome with weekly intra-arterial administration of reserpine and were impressed not only by the marked loosening of the skin but also by the striking effect on the Raynauds phenornena; the latter disappeared within a few weeks of treatment.

Normal human B cells produce autocrine growth factor in response to Staphylococcus aureus Cowan I strain (SAC). However, the functional role and molecular nature of the B cell derived-B cell growth factor (B-BCGF) are largely unknown. We have tried to investigate the nature of B-BCGF using mAb for several years. We report here that B- BCGF is capable of binding to hemoglobin (Hb). The concentrated culture supernatant from tonsillar B cells stimulated with SAC for 24 h was loaded into the fast protein liquid chromatography and ion-exchange chromatography. The peak with BCGF activity was shown to have a M.W. of 16-18 Kda in polyacrylamide gel electrophoresis followed by silver stain. Amino acid sequence of the fraction was found to identical to human hemoglobin (Hb) by more than 85%. However, Hb itself had no BCGF activity. The presence of Hb in culture supernatant was due to the contamination of SRBC during B cell purification. SRSC were completely removed from B cells by percoll-gradient centrifugation and B cells were stimulated with SAC and exogenous Hb was added to the cultures. The Hb fraction from FPLC again showed a BCGF activity. These data strongly suggested that BCGF binds to Hb. We confirmed this in dot blot as well as Western blot. The M.W of Hb-binding BCGF was 20 Kda. This information may provide a rapid progress in research of BCGF.

Angiogenesis is essential for the growth of solid tumors. Microvessel counts, which represent a measure of tumor angiogenesis, have been correlated with the overall survival of patients with a variety of malignancies. However, the significance of angiogenesis in renal cell carcinoma remains controversial. To determine whether angiogenesis correlates with prognosis of patients with renal cell carcinoma, we counted the microvessels within the primary tumors and compared their numbers with patients' prognosis. Tumor specimens from 42 patients were investigated. Microvessels were stained with anti-CD34 and anti-factor VIII-related antigen monoclonal antibodies. Significant correlation between microvessel counts for two antibodies was observed (r=0.875, p<0.01), although microvessel counts for CD34 were approximately two times higher. Microvessel counts were higher in clear cell than in non-clear cell carcinoma (p<0.05). These results suggest that immunostaining with anti-CD34 antibody may provide a more sensitive and accurate measure of tumor angiogenesis. There was no correlation between microvessel counts and nuclear grade, or TNM stage. In univariate analyses, nuclear grade and TNM stage were significantly associated with patient survival (p<0.01). But further studies on tumor angiogenesis of renal cell carcinoma are needed before it can be adopted as a prognostic marker.
