PURPOSE: To investigate the replication of HSV within cultured cell and axonal transport of HSV within the axon of the ciliary nerve following the injection of HSV into a cultured ciliary nerve. METHODS: The explant of the ciliary nerve was cultured with a medium containing nerve growth factor for 30 days when the suspension of HSV-1 (Kos strain) was introduced into the culture dish to co-culture with the ciliary nerve. The ciliary nerve was examined with transmission electron microscopy 30 days after culture and 6 days after co-culture with HSV. RESULTS: The ultrastructure of the explant of the ciliary nerve co-cultured with HSV showed that the viral capsid acquired a viral envelope and viral core, and a capsid and inclusion body within the nucleus. The enveloped virus was scattered within the vesicles of the cytoplasm. The virus-like particles were identified at the axonal fibers. CONCLUSIONS: The co-culture of the explant of the ciliary nerve and HSV showed the replicative process of the HSV within the cultured cell. The virus-like particles within the axon showed the evidence axonal transport of the virus under culture conditions.

PURPOSE: The purpose of this study was to compare motivation for rehabilitation, family support and adherence to rehabilitation and identify factors predicting adherence to rehabilitation between depressive and non-depressive stroke patients. METHODS: Stroke patients admitted to rehabilitation hospitals (n=159) participated in the study. Data were collected through self-reported questionnaires including general characteristics, depression, motivation for rehabilitation, family support and adherence to rehabilitation. The data were analyzed by descriptive statistics, t-test, χ² test, Pearson correlation coefficients and logistic regression using the SPSS/WIN 21.0 program. RESULTS: 62.9% of the subjects were identified as depressive patients. Motivation for rehabilitation (F=48.18, p=.020) and adherence to rehabilitation (F=9.68, p=.002) in depressive stroke patients were significantly lower than non-depressive stroke patients. Family support also in depressive group was lower than non-depressive group but there was no statistical significance (F=2.35, p=.127). Motivation for rehabilitation (OR=11.46), family support (OR=1.05) and onset period (less than 2 year)(OR=3.61) predicted the good adherence to rehabilitation in depressive stroke patients. CONCLUSION: The results of this study indicate that health professionals need to identify factors affecting adherence to rehabilitation and provide a nursing intervention considering the depression especially when caring for stroke patients.

Purpose: This study’s purpose is to examine the effects of nurses' incident reporting attitudes, their perceptions of importance of patient safety management, and patient safety culture on reporting patient safety events. Methods: We used a cross-sectional design with a convenience sample of 192 nurses with more than three months clinical experience from five provincial hospitals. The data were collected through an online structured self-report questionnaire from September 25 to October 15, 2022. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation coefficients, and stepwise multiple regression. Results: The most important influencing factors for the level of patient safety event reporting were perceptions of the importance of patient safety management (β=.24, p=.005), followed by patient safety culture (β=.23, p=.019), incident reporting attitude (β=.18, p=.016), and near miss reporting experience (β=.14, p=.022). The explanatory power of the model was 33%. Conclusion To increase the level of patient safety incident reporting, differentiated education and standardized work procedures are needed. Also, it is necessary to prepare policies that revitalize patient safety reporting systems at medical institutions as measures to prevent patient safety accidents and recurrences.

PURPOSE: This study was performed to investigate the growth pattern of the retinal vessel including retinal vascular endothelial cell and pericyte. METHODS: The sensory retina was detached from the eyecup obtained from donor's eye. The retinal vessel which was separated from the sensory retina was cultured in tissue culture media for 2, 3 and 4 weeks separately and examined by transmission electron microscopy. RESULTS: On the second week of tissue culture, both the retinal vascular endothelial cells and pericyte were intact in morphology in nuclear and cytoplasmic pattern. Both cells were partially detached from the surrounding basement membrane. On the third week of tissue culture, the cytoplasm of the retinal vascular endothelial cells and pericyte were degenerated, whereas the vascular endothelial cell were intact in nuclear and cytoplasmic profiles which were still partially surrounded by the basement membrane. CONCLUSIONS: These findings suggest that the survivability of the retinal vascular endothelial cells and pericyte may be limited for 2 and 3 weeks, separatedly under the ordinary culture medium.

NAG activity has been measured in the urine of hypertension, diabetes mellitus and renal disease subjects. Results have shown significantly higher levels of Urinary NAG in hypertension, diaetes and renal disease subjects compared to normal control Subjects group(P<0.001). Urinary NAG measurement is simple and accurate and it provides a valuable information in the early detection of renal dysfunction in hypertension and diabetes subjects and also in the follow up of these patients.

PURPOSE: To review the results of resections of heterotopic ossification around the hip in patients with central nervous system injuries. MATERIALS AND METHODS: Heterotopic ossification was resected in ten hips of eight patients and followed for at least one year. Average age was 38.1 years (range, 21-56 years). We reviewed the charts and the radiographs for overall patient function, location of the lesion, radiographic evidence of maturation and any recurrence. Heterotopic ossification was resected regardless of the result of bone scan. RESULTS: All patients showed improved function. Three minimal recurrences and one moderate recurrence were identified at the last follow-up radiography, but the range of motion had not decreased due to recurrence. CONCLUSION: Severe heterotopic ossification around the hip in patients with spastic paralysis was resected, and it was found that the range of motion was improved in all patients and that the chance of recurrence was minimal, even though the bone scan showed hot uptake on the bone scan.

This study was designed to observe anoxia-induced responses and to clarify their possible mechanisms in porcine basilar and circle of Willis arteries. Anoxia produced a transient vasoconstriction, which then recovered to the basal tension of a 3-5 min. later, and the reoxygenation that follows produced the biphasic(relaxation-contraction) response in the intact endothelial rings under resting tension. The anoxia-induced contraction was potentiated by pretreatment with KC1 and PGF2alpha. Reoxygenation produced only sustained relaxation. Removal of the endothelium and pretreatment with nimodipine or indomethacine markedly attenuated the anoxia-induced contractions. Anoxia transiently and significantly increased cyclic GMP contents in the endothelium-intact preparations, but did not affect them in the endothelium-removed ones. The above results suggest that anoxia-induced contraction is endothelium-dependent and is resultant to the release of a Prostaglandin-like substance(s) .

OBJECTIVE: This study was undertaken to compare the diagnostic performances of magnetic resonance imaging (MRI), MR myelography (MRM) and myelography in young soldiers with a herniated lumbar disc (HLD). METHODS: Sixty-five male soldiers with HLD comprised the study cohort. A visual analogue scale for low back pain (VAS-LBP), VAS for leg radiating pain (VAS-LP), and Oswestry disability index (ODI) were applied. Lumbar MR, MRM, and myelographic findings were checked and evaluated by four independent radiologists, respectively. Each radiologist was asked to score (1 to 5) the degree of disc protrusion and nerve root compression using modified grading systems devised by the North American Spine Society and Pfirrmann and the physical examination rules for conscription in the Republic of Korea. Correlated coefficients between clinical and radiological factors were calculated. Interpretational reproducibility between MRI and myelography by four bases were calculated and compared. RESULTS: Mean patient age was 20.5 +/- 1.1. Mean VAS-LBP and VAS-LP were 6.7 +/- 1.6 and 7.4 +/- 1.7, respectively. Mean ODI was 48.0 +/- 16.2%. Mean MRI, MRM, and myelography scores were 3.3 +/- 0.9, 3.5 +/- 1.0, and 3.9 +/- 1.1, respectively. All scores of diagnostic performances were significantly correlated (p < 0.05). However, none of these scores reflected the severity of patients' symptoms. There was no statistical difference of interpretational reproducibility between MRI and myelography. CONCLUSION: Although MRI and myelography are based on different principles, they produce similar interpretational reproducibility in young soldiers with a HLD. However, these modalities do not reflect the severity of symptoms.
