PURPOSE: We tried to outline the incidence and characteristics of meniscal tears in recent lesions and chronic insufficiency of the ACL. MATERIALS AND METHODS: Through this retrospective study of 103 reconstructions of the anterior cruciate ligament (ACL) performed between Jun 1996 to Sep 1998, according to a more accurate evaluation, ACL-deficient knees can be classified into two different stages (recent, chronic injuries). RESULTS: Overall, there was a significantly increasing incidence of meniscal tears in chronic injuries (P<0.05). A predominance of lateral meniscal tears were demonstrated with recent injuries, whereas the incidence of medial meniscal tears increased significantly with chronic injuries (P<0.05). CONCLUSIONS: This study highlights the increase of lateral meniscal lesion in recent ACL rupture and increase of severe meniscal lesion, especially medial meniscus, with progressive worsening of knee instability after an ACL injury. Although not significant, meniscal tears in the recent injuries were more amenable to repair. The results suggest that maximal meniscal preservation is best achieved with ACL reconstruction shortly after injury.

Transforming growth factor-beta (TGF-beta) has been suspected as a possible gene therapy candidate for orthopedic diseases. We demonstrated that the TGF-beta gene therapy can be applicable to orthopedic patients. After transfection of TGF-beta cDNA sequence to myoblasts [C2 (280)] and fibroblasts (NIH 3T3), stable cell lines with TGF-beta mRNA expression were selected by Northern analysis. To evaluate the possibility of clinical application of these cells to orthopedic diseases, the cells were injected into rabbit achilles tendon. Intratendinous injection was done to evaluate the viability of the cells and to determine the optimal concentration for in vivo expression. At 6 weeks after injection, the injected tendon was thickened with newly formed collagen. The results from this experiment indicates that these cells survived and stimulated matrix formation in rabbit achilles tendon. We concluded that TGF-beta cDNA transfected cells can be useful in the evaluation of TGF-beta biology in vivo.

TGF-p receptor mutation is now considered as one of the carcinogenic process of many tumors. To evaluate whether there is an abnormality in TGF-p type II receptor in osteosarcoma cell lines, we performed Northern analysis, cross-linking assay, luciferase activity and TGF-p growth inhibition assay in four osteosarcoma cell lines: G292, U202, HOS and SaOS. We also transfected the tumor cells with normal TGF-p type II receptor sequence to find if there is a possibility of gene therapy in osteosarcoma. In Northern analysis, Type II receptor expressions were decreased at SaOS, U202 and HOS cell lines. In cross-linking assay, all four cell lines didnt show type II receptor at their cell surface. The growth of these tumor cells were not suppressed by TGF-p. From these findings, we concluded that the normal production of TGF-p type II receptor was impaired in osteosarcoma. The transfection of these tumor cells with normal type II receptor sequence restored growth inhibition by TGF-p. This means even though TGF-p type II receptor is abnormal in osteosarcoma, we can restore its function by transfection of normal sequence. We think that the TGF-p type Il receptor gene therapy can be one of the treatment method for osteosarcoma in the future.

PURPOSE: This research was conducted to construct a model explaining the quality of life (QOL) related to undergraduate students' health. Social support, self-efficacy and self-esteem were used as exogenous variables while health promotion lifestyles, personal health care competency were endogenous variables. METHODS: A survey was conducted with a structured questionnaire including QOL, health promotion lifestyles, personal health care competency, social support, self-efficacy, and self-esteem. Data were collected from 269 undergraduate students with random sampling and then analyzed using structural equation modeling. RESULTS: Personal health care competency, health promotion lifestyles, social support, self-esteem had both direct and indirect effects while self-efficacy had indirect effects on the QOL of undergraduate students. Especially, social support, self-efficacy and self-esteem influenced positively to the QOL while greater health promotion lifestyles and personal health care competency improved QOL. Thus, personal health care competency and health promotion lifestyles were important mediator for positive QOL in undergraduate students. CONCLUSION: Interventions aiming to enhance health promotion lifestyles and personal health care competency, based on the results of this study, are required to help positive QOL in undergraduate students. Our results can serve as basic data for designing such interventions.

The aim of this study was to determine the applicability of reverse transcription and polymerase chain reaction (RT/PCR) for routine diagnostic use and for the detection of enteroviral mentigitis. Primers were selected in the highly conserved part of the 5'-non-coding of the enteroviral genome. Enteroviral RNA was detected by the RT/PCR in routinely collected cerebrospinal fluids (CSF) of patients with aseptic meningitis who had admitted to the dept. Of Pediatrics. MinJoong Hospital, KonKuk University from May to July 1993. Enteroviral RNA was detected in one third of CSF specimen. Our results demonstrate the significance of the RT/PCR in the diagnosis of enteroviral meningitis.

This paper proposes a system for nursing diagnosis and intervention management that is using nursing outcome indicators to guide the nursing intervention. In Korea, it has been studied on computerization of nursing process, but most of the studies are on the management of nursing records and not on the databases of nursing intervention. So far, the actual nursing processes have been performed by individual nurses' judgement without any supporting programs. Therefore, we provide the system with standardized database for nursing diagnosis and interventions so that nurses can make more accurate diagnoses and perform more adequate interventions. For that purpose, we have developed an algorithm that links nursing outcome indicators to nursing diagnoses and interventions. As a result, we expect the system can be used in many hospitals efficiently in the future after pilot operations.

PURPOSE: To compare the rate of intraoperative sclerotomy-related retinal breaks (SRRB) between 20- and 23-gauge vitrectomy for proliferative diabetic retinopathy (PDR). METHODS: Medical records of 62 consecutive eyes of 54 patients who underwent 20-gauge pars plana vitrectomy (PPV) and 63 consecutive eyes of 55 patients who received 23-gauge transconjunctival sutureless vitrectomy were retrospectively reviewed. RESULTS: Three (4.8%) out of 62 eyes in the 20-gauge group had SRRB and 1 (1.6%) eye developed retinal detachment at 4 months postoperatively, while 2 (3.2%) out of 63 eyes in the 23-gauge group had SRRB and 1 (1.6%) eye developed retinal detachment at 3 months postoperatively. CONCLUSIONS: There were no significant differences in the rates of sclerotomy-related retinal breaks and sclerotomy-related retinal detachments between 20-gauge PPV and 23-gauge PPV for PDR.

OBJECTIVES: The authors conducted the study to evaluate bias when potentially diseased subjects were included in cohort members while analyzing risk factors of chronic liver diseases. METHODS: Total of 14,529 subjects were followed up for the incidence of liver diseases from January 1993 to June 1997. We have used databases of insurance company with medical records, cancer registry, and death certificate data to identify 102 incident cases. The cohort members were classified into potentially diseased group(n=2,217) when they were HBsAg positive, serum GPT levels higher than 40 units, or had or has liver diseases in baseline surveys. Cox' model were used for potentially diseased group, other members, and total subjects, respectively. RESULTS: The risk factors profiles were similar for total and potentially diseased subjects: HBsAg positivity, history of acute liver disease, and recent quittance of smoking or drinking increased the risk, while intake of pork and coffee decreased it. For the potentially diseased, obesity showed marginally significant protective effect. Analysis of subjects excluding the potentially diseased showed distinct profiles: obesity increased the risk, while quitting smoking or drinking had no association. For these intake of raw liver or processed fish or soybean paste stew increased risk; HBsAg positivity, higher levels of liver enzymes and history of acute liver diseases increased the risk. CONCLUSIONS: The results suggested the potential bias in risk ratio estimates when potentially diseased subjects were included in cohort study on chronic liver diseases, especially for lifestyles possibly modified after disease onset. The analytic strategy excluding potentially diseased subjects was considered appropriate for identifying risk factors for chronic liver diseases.
