1.Effects of Some Drugs and Toxins on Positive Rate of Y-Body in Leukocytes of Rabbits.
Korean Journal of Urology 1976;17(2):77-94
This study was carried out to investigate the response of interphase Y chromosome to some drugs and toxins by observing the rate of leukocytes showing Y-body in the peripheral blood. The interphase Y chromosomes of blood leukocytes were stained with quinacrine mustard and the animals used were rabbits, rats and guinea pies. Y-bodies of leukocytes were studied in the animals as well as in man. Changes in positive rate of Y-body in leukocytes and total leukocyte count were observed in the rabbits administered with drug or toxin. The results concerning the rate of Y-body were as follows: 1. Y-bodies were present in the blood leukocytes of the animals. However positive rates in mononuclear and polymorphonuclear leukocytes were lower in animals that in man. The positive rate of Y-body was higher in mononuclear leukocytes than in polymorphonuclear leukocytes in the animals as in man. 2. Bacterial toxins such as typhoid, D.P.T. and cholera vaccines and anticancer drugs such as busulfan and endoxan reduced the positive rates of Y-body both in mononuclear leukocytes and in polymorphonuclear leukocytes. 3. Benzene known as bone marrow toxin reduced the positive rate of Y-body in mononuclear leukocytes, but not that in polymorphonuclear leukocytes. Quinine known as general protoplasmic poison reduced the positive rate of Y-body not only in mononuclear leukocytes but also in polymorphonuclear leukocytes. 4. Antibiotics such as tetracycline and chloramphenicol and steroid hormones such as estrogen, testosterone and prednisolone had no effects on the positive rate of Y-body both in mononuclear leukocytes and in polymorphonuclear leukocytes.

2.The Changes in Axial and Radial Diffusivity in a Patient with Clinically Mild Encephalitis/Encephalopathy with a Reversible Splenial Lesion
Investigative Magnetic Resonance Imaging 2020;24(3):174-177
Multiple studies have established that mild encephalitis/encephalopathy with a reversible splenial lesion (MERS) exhibits reversible diffusion restriction in the white matter, including the splenium. There have been a few previous reports of the change in fractional anisotropy (FA) of MERS cases. Herein, we report the longitudinal changes in axial and radial diffusivity (AD and RD), and FA in a 15-year-old boy patient with MERS. Our case demonstrated that a MERS lesion had a significant drop of AD in the early period and gradual recovery. On the contrary, RD did not show any significant change.

Purpose:
The aim of this study was to compare the short-term outcomes between laparoscopic liver resection (LLR) and open liver resection (OLR) in elderly patients with hepatic tumors.
Methods:
From January 2013 to December 2019, a retrospective study was conducted for a total of 143 patients with over 70 years of age, who underwent liver resection for hepatic tumors. Forty-five patients who received biliary reconstruction at the same time were excluded. According to surgical approaches, 98 patients were classified into LLR and OLR groups. All postoperative complications were classified according to the Clavien-Dindo grading system and the Comprehensive Complication Index (CCI).
Results:
Incidence of the postoperative complications was not statistically different between LLR and OLR groups. The CCI was significantly lower in the LLR group, with a median of 8.556, and a median of 19.698 in the OLR group (p=0.042). The length of hospital stay in the LLR group was significantly shorter than in the OLR group (p=0.008).
Conclusion
LLR is safe and feasible as a treatment for hepatic tumor in elderly patients with potentially less postoperative complications compared to OLR.
8.A Study on Impact of Nursing Work Environment, Interpersonal Skills, and Grit on Field Adaptation of Nurses Who Have Experienced Department Transfers
Journal of Korean Critical Care Nursing 2024;17(2):71-82
Purpose:
: This study aims to identify the factors influencing field adaptation among nurses who have undergone department transfers, by examining the levels of and the relationships between their nursing work environment, interpersonal skills, grit, and field adaptation.
Methods:
: The study involved 137 nurses who had experienced at least one department transfer within the last three years across two hospitals. Data analysis was performed using SPSS/WIN 29.0, involving descriptive statistics, means, standard deviations, independent t-tests, one-way ANOVA, Scheffé post-hoc tests, Pearson correlation coefficients, and multiple regression analysis (enter method).
Results:
: Factors affecting field adaptation included the nursing work environment (β=.37, p <.001), interpersonal skills (β=.19, p =.021) and grit (β=.18, p =.025), with a total explanatory power of 31% (F=12.16, p <.001).
Conclusion
: This study contributes insights into effective nursing personnel management, offers foundational data for managing department transfers, and aims to improve the overall quality of nursing care.

The cause of essential hypertension is yet unknown, but in general is caused by interaction of hereditary factors, diet, obesity, lack of exercise and stress. The aging process influences various physiological mechanism related to regulation of blood pressure. So elderly hypertensives have a tendancy to consider the disease as a result of the physiological aging process. This attitude causes many complications, worsening of the disease and even early death because of inappropriate care. In order to improve self-management of elderly hypertensives in this study the researcher examined the effect of blood pressure regulation by an education program that improves self-care behavior, through increasing self-efficacy. The education program consisted of group education on hypertension and self-care strategies, and encouraging and reinforcing self-efficacy resources such as verbal persuation, performance accomplishment and vicarious experiences. A quasi-experimental pre-and post-test design was used. Thirty-two elderly hypertensives participated in the study. Eighteen in the education group and fourteen in the control group. The education program consisted of eight sessions twice a week for four weeks. There was no intervention for the control group. Data were analysed using SPSS for Windows(Version 8.0). The results were as follows. 1. There was a significant decrease in systolic and diastolic blood pressure between the experimental group and control group over three different times, and interaction by groups and over time. 2. There was no significant difference in the level of self-care behavior between the experimental group and control group over three different times, and interaction by groups and over time. 3. There was significant difference in self-efficacy of experimental and control group, depending on the measuring period, but there was no difference between these groups on interaction by groups and over time. 4. There was positive correlation between self efficacy and self care behavior depending on the measuring period. There was negative correlation between diastolic blood pressure and self-care behavior on the posttest of the program, and between systolic blood pressure and self-care behavior on the follow-up test of the program. Findings indicate that this study will contribute to develop nursing strategies for the regulation of blood pressure for the elderly, which is easy for the elderly to learn as a nonpharmacologic approach.

10.Bacteriological Study on Chronic Prostatitis.
Korean Journal of Urology 1982;23(4):527-534
A bacteriological study was made on 21 cases of the chronic prostatitis suspected by subjective symptoms, microscopic findings of urine, rectal findings of prostate and microscopic findings of prostatic secretion during the period from June to October 1980, and clinical observation was also performed. The results were summarized as follows; 1. The distribution of age showed the highest incidence in 20 to 39 years (16 cases: 76.2%). 2. 13 cases (61.9%) of patients had previously experienced acute or chronic urethritis. 3. Major subjective symptoms consisted of pollakisuria (12 cases: 57.1%), perineal discomfort and urethral discomfort in order of frequency. 4. On rectal palpation of prostate, 18 cases (85.7%) were abnormal in consistency. Most of the prostate were normal in size, but 9 cases enlarged and 1 case was small. 5. Majority of the cases (18 cases: 85.7%) were normal in microscopic examination of urine. 6. In microscopic findings of prostatic secretion, 17 cases (81.0%) showed W.B.C. more than 10/H.P.F. 7. In 21 cases in which urine and prostatic secretion culture were done, microorganisms were cultured in 9 cases (42.9%) and no growth was noted in 12 cases (57.1%). There were 3 cases of mixed infection. The isolated microorganisms revealed 6 cases of Staphylococcus aureus, 3 cases of E. coli, 1 case of Staphylococcus epidermidis, 1 case of Pseudomonas fluoresces and 1 case of Alcaligenes. 8. The mean colony counts were as follows. VB1: 881+/-583 colonies/ml VB2: 123+/-112 colonies/ml EPS: 57,778+/-28,299 colonies/ml VB3: 5,389+/-4,745 colonies/ml There was more predominant growth in EPS and VB3 than VB1 and VB2. 9. Microscopic findings of biopsied prostatic tissue showed infiltration of chronic inflammatory cells in all 4 cases. The results of bacterial culture of prostatic tissue were negative in 2 cases, Staphylococcus aureus in 1 case and E. coli in 1 case. The isolated microorganisms were identical to prostatic secretion cultures. 10. The pH of prostatic secretions were 14 cases (66.7%) in 7.7 to 8.0 and 4 cases (19.0%) in over 8.0. There was no significant difference in pH of prostatic secretions between prostatic secretion culture positive group and culture negative group.
