Congenital Hyperextension of the Knee is a extremly rare deformity, in which the tibia is displaced anteriorly in relation to the femur. It is usually classified into three subtypes according to severity of the status: genu recurvatum, subluxation and dislocation. (Curtis and Fisher) We experienced a genu recurvatum type of congenital hyperextension of the knee in June, 1976.

OBJECTIVES: Culture of sputum is apt to be contaminated through oral cavity and proximal airway. Therefore, identification of true etiologic agents by sputum culture is not always reliable. In order to differentiate the pulmonary infection from non-infectious disease and to identify the true etiologic agent of acute pulmonary infection, we used PSB(Protected Specimen Brushing) and evaluated the efficacy of PSB. METHODS: In 168 patients with acute febrile illness with pulmonary infiltrations(male 106, female: 61, mean age: 49.5+/-17.6), we performed PSB via a bronchoscope and compared the results along with blood culture and sputum culture. Protected specimen brush was introduced through biopsy channel of bronchoscope and was rotated within the purulent secretions. Tip of the brush was severed with aseptic technique and was immersed in 1cc of Ringer's lactate solution and vigorously mixed for 1 minute. The specimen was submitted for quantitative culture within 15 minutes and was regarded positive culture if colony forming units were above 10(3)/ml. RESULTS: Using PSB for the diagnosis of pulmonary infection, sensitivity was 71.1% and specificity was 84.296. PSB was helpful in identifing true etiologic agent among several potentially pathogenic organisms. Using PSB for the diagnosis of UAP (ventilator associated pneumonia), sensitivity was 72.4% and specificity was 100%. CONCLUSION: Use of PSB can be a helpful method for the diagnosis of pulmonary infection and identification of its etiologic agents.

BACKGROUND: Eosinophilic leukocytes are prominent cellular participants in the pathogenesis of allergic disease and asthma. Chemotaxis is still a very useful method in evaluating the response of human eosinophil to novel modulators. Degranulated mast cells and activated T lymphocytes are responsible for the pathophysiology of asthma and tryptase is one of most important proteases released after activation of mast cells. The purpose of this study was to investigate the actions of trypsin and chymotrypsin on eosinophils in terms of chemotaxis and activation. METHOD: Eosinophils were isolated by negative immunoselection from the peripheral blood of atopic donors. Chemotaxis was studied by using micro-Boyden chambers and ECP release was assayed by fluoroimmunoassay. RESULTS: Eosinophil showed a chemotactic response to trypsin. Maximal chemotactic response was with 1000microg/ml trypsin (56.52 +/- 14.50/HPF) which was comparable to PAF. But chymotrypsin showed no significant chemotactic response to eosinophils. Trypsin at the concentration of 10, 100,1000microg/ml induced secretion of ECP, which at the concentration of 10microg/ml represented about 2.7 times of the spontaneous rate of release. Soybean protease inhibitor reduced trypsin induced ECP release. CONCLUSION: Trypsin can induce chemotactic response to eosinophils and activation of eosinophils that can induce secretion of ECP. On the contrary, chymotrypsin showed no direct effect on eosinophils. We propose a role of trypsin on the chemotaxis and activation of eosinophils.

BACKGROUND: Tc-99m myocardial perfusion imaging agents have recently found wide spread use as detecting agents of coronary diseases. Unfortunately, false positive results are not infrequent. METHODS: We analyzed Tc-99m myocardial perfusion SPECT (Tc-SPECT) findings in angina patients showing normal coronary angiography. Seventy patients who underwent myocardial SPECT wihin one month of coronary angiography which revealed no significant stenosis were studied. RESULTS: Forty six (65.7%) patients showed perfusion defects on Tc-SPECT. Eighteen were due to soft tissue attenuation, thirteen were due to technical problems such as low count rate, six were associated with intraventricular conduction abnormalities, four with coronary spasms, three with old infarctions, and one with slow coronary flow. CONCLUSION: Photon attenuation and inadequate count rates were the main causes of false positive results on myocardial SPECT imaging with Tc-99m agents. However, pathological conditions such as conduction disturbance, coronary spasm or slow coronary flow were also associated with positive SPECT findings in patients with normal coronary angiograms.

A murime monoclonal antibody (mAb) specific for the envelope glycoprotein gp120 of human immunodeficiency virus type-I (HIV-1) was chemically coupled to pokeweed antiviral protein (PAP) from Phytolacca americana. The immunotoxin was purified by FPLC using 5200 colum. The purified immunotoxin efficiently bound to HIV-infected T cells as evidenced by fluorescence-activated cell sorter analysis. The immunotoxin selectively killed human T lymphoid lines infected with HIV-lIIIB at less than 250 pM of the immunotoxin cells, while PAP or mAb alone did not have any significant effect on infected cells. The uninfected control T cell lines were not affected. Human cells infected with HIV-2 or other HIV-1 strains were not killed, suggesting that the killing depends completely on the antibody used for coupling. These in vitro results suggest that the PAP-mAb conjugate may be used to selectively remove cells expressing viral antigens from individuals infected with HIV.
