The anthelminthic effect of phenylene-diisothiocyanate-(1,4)(=Jonit) was studied on the eighty three cases infected with Ancylostoma duodenale. For the evalution, the number of eggs per gram of feces on all these cases was calculated before treatment. The follow-up for the egg reduction was carried out over a period of four weeks. The sixty-seven cases were treated in dosage schedule of 3 x 100 mg every 12 hours. The cure rates - the rate of negative conversion of eggs - was 74.6 percent and the total egg reduction rate of 94.2% was obtained. The ten out of 14 cases treated in the dosage schedule of 2 x 100 mg every 12 hours showed 100% egg reduction and the cure rate was 71.4%. In this group. the total egg reduction rate of 78.6% was noted. In the dosage schedule of 2 x 50 mg every 12 hours the remainder, two out of total 83 cases showed 100% egg reduction. Side effects were observed as being mild, 51 cases (56.6%) were free of side reactions and the most frequently noted side effects were vertigo and diarrhea. From the above results, it is concluded that Jonit is an effective antheminthic against Ancylostoma duodenale and its effectiveness is quite equivalent to that of a known recommended anti-hookworm products.

Infection in primary total hip arthroplasty may cause catastrophic results and is the major reason for implant failure. The purpose of this study was to evaluate the utility of the hip joint fluid culture as a method of predicting the possibility of a hip joint infection by calculating the sensitivity, specificity and accuracy. We performed 628 primary total hip arthroplasty and aerobic and anaerobic bacterial cultures for hip joint fluid between January 1989 and June 1996. The hip joint fluid culture was routinely performed to evaluate the utility of the femoral head for bone banking. Thirty-two cases out of the 628 hips showed positive intraoperative culture and 596 cases showed negative intraoperative culture. The isolated organisms from 32 positive cultures were 11 for Staphylococcus aureus, eight for Staphylococcus coagulase negative, seven for Enterococcus, three for E.coli and one each for Enterobacter, Acinetobacter and Pseudomonas. Anaerobic culture was negative in all cases. In the positive intraoperative culture cases, none had delayed infection during the follow-up period. But in the negative intraoperative culture cases, one case had acute infection and two cases had delayed infection. In the case with acute infection, Staphylococcus aureus was isolated and on two cases with delayed infection, Enterococcus and Staphylococcus coagulase negative were isolated, respectively. All 32 positive culture cases were fa~lse positive and 595 negative culture cases were true negative and one negative culture case was fa~lse negative. The sensitivity of the hip joint culture was 0%, the specificity was 94.9% and the accuracy was 0%. The specificity of hip joint fluid culture in primary total hip arthroplasty was high, hut the sensitivity score was zero. Therefore, the hip joint fluid culture should not be used for a routine check of infection status in primary total hip arthroplasty. We recommend the hip joint fluid culture in revision arthroplasty or hips in which infection is clinically suspected.

Brain size is a useful parameter describing ontogenic character and function. Despite its potential contribution to functional study and diagnosis of disease, it has been hampered by poor assessment tools in vivo and postmortem changes. Recent development of medical imaging techniques such as MRI and CT enable us to understand brain structures in vivo. Many morphometirc studies of the brain has given us new insights in the field of functional neuroanatomy and neuropsychiatric diseases. In spite of these advances, volumetric data of normal Korean brain is not available yet. As an initial approach to Korean standard brain size, we measured the cerebellar volume between 20 and 80 years old Koreans. The MRI films free from lesions in brain was analyzed and measured by NIH image program. The Korean cerebellar volume were ranged between 86.2cm(3) and 141.3 cm(3) and average male cerebellum volume was significantly larger than that of female[male : 118.2+/-11.2cm(3)] > female : 108.0+/-9.6cm(3), P=0.1021E-07<0.05]. And we could not find volume change according to aging process. This is the first report on normal Korean cerebellar volume and the presence of gender difference in the Korean cerebellar volume. These data will be used for the standard useful in studying cerebellar function and cerebellum associated disorders in the future.

Neonatal Medicine 2022;29(1):46-54
Purpose:
The study aimed to examine whether prophylactic surfactant replacement therapy (SRT) with less invasive surfactant administration (LISA) by tracheal catheterization in a group of spontaneously breathing preterm infants would improve clinical outcomes compared to prophylactic SRT with the INtubation-SURfactantExtubation (INSURE) method.
Methods:
We compared 20 spontaneously breathing preterm infants, 25 to 29 weeks of gestation or with a birth weight of less than 1,250 g, treated with prophylactic SRT using a gastric tube (LISA group), to the 20 spontaneously breathing preterm infants matched by gestational age and birth weight, managed with prophylactic SRT via the INSURE method (INSURE group, historical control).
Results:
The LISA group had lower rates of mechanical ventilation (MV) 72 hours after birth (P=0.019) and at any time (P=0.025), lower frequency of bradycardia during SRT (P=0.031), and lower median duration of MV than the INSURE group (P=0.038). In multivariate analysis, the LISA method was associated with a significantly lower likelihood of receiving invasive ventilation during hospitalization (odds ratio [OR], 0.029; 95% confidence interval [CI], 0.001 to 0.938; P=0.046) and a decreased frequency of bradycardia during SRT (OR, 0.020; 95% CI, 0.001 to 0.535; P=0.020) as compared to the INSURE method.
Conclusion
Prophylactic SRT using LISA via tracheal catheterization in preterm infants may significantly reduce exposure to MV during hospitalization and bradycardia during surfactant administration.

SUMMARY OF LITERATURE REVIEW: Many authors haute described the association between lumbar disc degeneration and segmental instability but it has not been delineated in detail. OBJECTIVES: To compare the MRI assessment of disc degeneration with the conventional plain X-ray evaluation of the intervertebral disc, in order to study lumbar segmental instability. MATERIALS AND METHODS: In 75 patients with low back pain and/or sciatica, we analyzed disc space height, angular displacement, and horizontal displacement on plain radiographs of the lumbar spine. These parameters were compared with the grade of disc degeneration as evaluated by magnetic resonance Imaging. STUDY DESIGN: We analyzed the association between grade of disc degeneration as evaluated by magnetic resonance imaging assessment and segmental instability as evaluated by plain radiographs of the lumbar spine. RESULTS: Disc space height was decreased In proportion to the grade of disc degeneration. Angular displacement was increased according to the grade of disc degeneration, but significantly less with severe degeneration, accompanied by a tendency to stabilization of the motion segment. Horizontal displacement was not correlated with the grade of disc degeneration CONCLUSIONS: The incidence of lumbar segmental instability increased in proportion to the grade of disc degeneration but significantly decreased with severe disc degeneration.

OBJECTIVES: Aim of this study was to compare quality of life (QOL) in obsessive compulsive disorder (OCD), panic disorder (PD) and healthy controls. Additionally, relationship between clinical factors in patients and their QOL were explored. METHODS: 49 patients with OCD, 109 patients with PD and 54 healthy controls were recruited. Total scores and scores of each domain of WHO Quality of Life scale (WHOQOL) were compared in the three groups. Correlation analysis and regression analysis were performed to examine the relationship between QOL and the clinical characteristics in the patient group. RESULTS: Total scores and scores of all domains except environmental domain of WHOQOL in patient group were decreased compared to those in healthy control. Scores of social and psychological domains in the OCD group were lower than those in the PD group. The severity of agoraphobia and depression were factors affecting the QOL in the PD group. For the OCD group, comorbid depression was related to social and psychological domain of WHOQOL. CONCLUSION: QOL in patients with OCD and PD was poorer than that of healthy controls. Social relationships and psychological functioning may be poorer in patients with OCD than patients with PD. The severity of depression and agoraphobia predicted QOL in patients with PD. Comorbid depression in OCD might be a predictor of poor QOL.

BACKGROUND: Cancer invasion and metastasis require the dissolution of the extracellular matrix in which several proteolytic enzymes are Involved. One of these enzymes is the urokinase - type plasminogen activator(u-PA), and plasminogen activator inhibitors(PAI-1, PAI-2) a]so have a possible role in cancer invasion and metastasis by protection of cancer itself from proteolysis by u-PA. It has been reported that the love]s of u-PA and plasminogen activator inhibitors in various cancer tissues are significantly higher than those in normal tissues and have significant correlations with tumor size and lymph node involvement Here, we measured the concentration of plasma u-PA and PAI- 1 antigens in the patients with lung cancer and compared the concentration of them with histologic types and staging parameters. METHODS: We measured the concentration of plasma u-PA and PAI-1 antigens using commercial ELISA kit in 37 lung cancer patients, 21 benign lung disease patients and 24 age-matched healthy controls, and we compared the concentration of them with histologic types and staging parameters in lung cancer patients. RESULTS: The concentration of u-PA was 1.0α0.3ng/mL in controls, 1.0α0.3ng/mL in benign lung disease patients and 0.9α0.3ng/mL in lung cancer patients. The concentration of PAI-1 was 14.2α6.7ng/mL in controls, 14.9α6.3ng/mL in benign lung disease patients, and 22.1 α9.8ng/mL in lung cancer patients. The concentration of PAI- 1 in lung cancer patients was higher than those of benign lung disease patients and controls. The concentration of u-PA was 0.7α0.4ng/mL in squamous cell carcinoma, 0.8α 0.3ng/mL in adenocarcinoma, 0.9ng/mL in large cell carcinoma, and 1.1α0.7ng/mL in small cell carcinoma. The concert traction of PAI-1 was 22.3α7.2ng/mL in squamous cell carcinoma, 22.6α9.9ng/mL in adenocarcinoma, 42ng/mL in large cell carcinoma, and 16.0α14.2ng/mL in small cell carcinoma. The concentration of u-PA was 0.74ng/mL in stage I, 1.2α0.6ng/mL in stage II, 0.7 α 0.4ng/mL in stage IIIA, 0.7α0.4ng/mL in stage IIIB, and 0.7α0.3ng/mL in stage IV. The concentration of PAI-1 was 21.8ng/mL in stage I, 22.7α8.7ng/mL in stage II, 18.4 α4.9ng/mL in stage IIIA, 25.3α9.0ng/mL in stage IIIB, and 21.5α10.8ng /mL in stage IV. When we divided T stage unto T1-3 and 74, the concentration of u-PA was 0.8α 0.4ng/mL in T1-3 and 0.7α0.4ng/mL in T4, and the concentration of PAI-1 was 17.9α 5.6ng/mL in T1-3 and 26.1α9.1ng/mL in T4. The concentration of PAI-1 in T4 was significantly higher than that in T1-3. The concentration of u-PA was 0.8α 0.4ng/mL in M0 and 0.7α0.3ng/mL in Ml, and the concentration of PAI-1 was 23.6α8.3ng/mL in M0 and 21.5α10.8ng/mL in M1 CONCLUSIONS: The plasma levels of PAI-1 in lung cancer were higher than benign lung disease and control, and the plasma levels of PAI-1 in 74 were significantly higher than T1-3. These findings suggest involvement of PAI-1 with local invasion of lung cancer, but it should be confirmed by the data on comparison with pathological staging and tissue level in lung cancer.
