BACKGROUND: Recently, according to many studies, variable factors have been known to be associated with physical fitness. The factors such as obesity and inactivity are associated with poor physical fitness, but regular exercise is associated with good physical fitness. In our country, these studies are not yet reported. And so, this study was designed to investigate the factors associat,ed with physical fitness. METHODS: From May 1st, until July 30th 1996, we recruited the 411 subjects who visited the Health Promotion Center at Seoul National University Hospital. Data related to sex, age, exercise, job, cigarette smoking, alcohol consumption were obtained by self-administered Questionnaire. Obesity index was calculated by the percentage of standard body weight. And VO2max were obtained by submaximal bicycle ergometer test. High level exercise group was defined as the persons who had taken exercise more than 3 times a week and 20 minutes per session, and moderate exercise group was defined as the persons who had taken exercise one or two times a week and 20 minutes per session, and sedentary group was defined as the persons who had taken exercise more than 20 minutes less than one time per week. RESULTS: The subjects were 230 males(56%), total numbers were 411. The results were as follows. Compaired to women and nonexercise group, men and exercise group had high VO2max(p<0.005). The relationship between VO2max and age showed negative, and the VO2max of obese group(obesity index>_120) was greater than that of nonobese group. Any significant relationships between VO2max and job, disease were not found. In multiple regression analysis, significant relationships between VO2max and age, sex, exercise type, and obesity index were observed(p<0.01). CONCLUSIONS: We concluded that there were significant relationships between VO2max and obesity index, exercise group.

The authors analyzed 52 patients with traumatic cervical fracture and dislocation admitted to the department of neurosurgery, Gyeongsang National University Hospital between July, 1989 and December, 1993. The most common age group was 21-30 years old, and 46 were male. The most frequent cause of injury was motor vehicle accident. High cervical injuries were 11 cases and mid-low cervical injuries were 41 cases. 34 cases had surgical intervention by anterior approach with bone graft only(5), anterior approach with bone graft and instrumentation(9), posterior approach with wiring and bone graft(18) and total laminectomy(2). The others had conservative treatment and immobilized by traction(9), Halo-vest(8) or neck collar(1). The average post of immobilization of conservatively treated patients was 9.7weeks, anterior approach without instrumentation was 9 weeks and posterior approach was 5.4 weeks, but patients who treated by anterior approach with instrumentation keep soft collar only. At final follow-up, no significant differences were noted between surgically and conservatively treated group but initial neurologic state correlates with prognosis, independent of modality of treatment. Thus the surgical intervention does not significantly influence the prognosis of the patient but shortens the duration of postoperative immobilization.

BACKGROUND: Candida species are not only the leading cause of nosocomial fungal infections but also the important cause of infections in the immunocompromised hosts. Epidemiologic study of nosocomial candidiasis has been difficult because of the lack of a reliable typing system. We performed molecular epidemiologic study by using RFA and Southem hybridization for typing of candida isolates from patiients. METHODS: A total of 27 candida isolates from 19 immunocompromised patients were studied. Morphotyping and biotyping were done by germ tube test and API 20C system, respectively. Candidial chromosomal DNA was extracted, digested with EcoRI, HindalII and RFA was done. Southem hybridization of chromosomal DNA was also done with digoxigen-labelled Candial albicans-specific DNA probe. RESULTS: The time-period of development of oral candidiasis after admission was 5-14 days (mean: 8 days). C.albicans was the most common species (19), followed by C tropiadis (2), C glabn#zta (2), C.paratropicalis (2), and C parapsilosis (1). The subtypes of Candida species by RFA of chromosomal DNA were C. albieans, 12 types , C tropicalis, 2 types, C glabrata, 2 types ; C.parapsilasis, 1 type ; C. paratropicalis, 1 type. For 7 (87.5%) of 8 patients, RFA pattern of one isolate was identical to that of the other isolates. CONCLUSION: RFA of candidial chromosomal DNA results were obtainable within days. RFA showed high reproducibility, typeability and good discrimination power between isolates, provided a robust system that may be used rapidly to identify outbreaks of nosocomial candidiasis.

PURPOSE: Nitric oxide (NO) and phosphodiesterases (PDEs) play key roles in mediating relaxation of corpus cavernosal smooth muscle by increasing intracellular cGMP level. Here, we investigated effects of NO-donor (sodium nitroprusside, SNP) and penile specific type-V PDE inhibitor (zaprinast) in human and rabbit corpus cavernosal cells and tissues in vitro. MATERIALS AND METHODS: The cultured smooth muscle cells and tissues of human and rabbit corpus cavernosum were treated with increasing concentrations of SNP or zaprinast for 5 and 20 minutes, respectively, and intracellular cGMP levels were measured by radioimmunoassay. Organ bath study was performed to measure the relaxation effects of drugs on precontracted corpus cavernosal muscle strips. RESULTS: Although both NO-donor and type-V PDE inhibitor effectively stimulated the accumulation of cGMP in a dose-dependent manner, magnitude of cGMP increase and specificity of drug were found to be species-dependent. In human corpus cavernosal tissues, cGMP was increased upto 10- and 5-folds by SNP and zaprinast, respectively. However, magnitude of increase was much less in cultured smooth muscle cells. In rabbit, SNP effect was most prominent in cultured cells and effects of SNP and zaprinast were modest in tissues. Both agents also resulted in effective relaxation of human and rabbit cavernosal tissue strips. Similar patterns of dose-response curves were shown between results from the organ bath studies and cGMP radioimmunoassay with cavernosal smooth muscle cells. CONCLUSIONS: Present results show that effects of SNP and zaprinast are not coincident in different species, suggesting possible species-specificities of these two agents. Measurement of cGMP changes in cultured cavernosal smooth muscles cells could be reflected to the relaxation effects of drugs on corpus cavernosal muscle strips.

PURPOSE: To evaluate the classification and treatment results about the injury of carpometacarpal (CMC) joint with the fracture of hamate. MATERIALS AND METHODS: The authors categorized into 3 types (I, II, III) according to the location of injured CMC joint and type II was subdivided into 2 type (a, b) according to the size of coronal fragment of hamate fracture-type I: fracture-dislocation of 5th CMC joint with small-sized fragment or avulsion fracture of hamate, type IIa: fracture-dislocation of 4th and 5th CMC joint with small-sized fragment or avulsion fracture of hamate, type IIb: fracture-dislocation of 4th and 5th CMC joint with coronal fracture of hamate body presenting an oblique or coronal splitting fracture, and type III: type II injury associated with injury of 3rd CMC joint or coronal plane fracture of capitate. All cases were carried out the operative treatment. And radiologic results and clinical results were evaluated. RESULTS: Type I were 2 cases, type IIa 4, type IIb 5, and type III 3. Twelve of 14 cases were excellent or good results, 1 case (type III) was fair, and 1 case (type IIa) was poor. All cases obtained anatomic reduction of CMC joint. But, the posttraumatic arthritis was observed in 1 case (poor) and the displacement of non-fixed hamate fragment was observed in 1 case (fair). CONCLUSION: We think that it may get more favorable outcomes by the fixation of the relative large fragment of hamate with anatomical reduction of CMC joint.

Neonatal genital prolapse is very rare and is usually associated with meningomyelocele or other anomalies of the central nervous system. Synonyms of genital prolapse are sacropubic hernia, pelvic relaxation, and pelvic organ prolapse. There are two types of genital prolapse including vaginal prolapse and uterovaginal prolapse. We experienced a case of uterovaginal prolapse in a 30 day-old premature infant, which was resolved with hypertonic saline pack on the 78th day of life. We report a case with the review of the literatures.

OBJECTIVES: Power spectrum analysis decomposes the heart rate signal into its frequency components and facilitates separation of sympathetic (low frequency) and parasympathetic (high frequency) activity. In congestive heart failure, augmented sympathetic tone and decreased parasympathetic tone were found. Autonomic nervous system was normalized 6 months after myocardial infarction. So we compared the autonomic nervous system activity by the heart rate variability in congestive heart failure and old myocardial infarction. METHODS: The protocol involved 20 healthy subjects (Group 1), 5 congestive heart failure patients not caused by myocardial infarction (Group 2), 4 congestive heart failure patients due to myocardial infarction and 11 old myocardial infarction patients without heart failure. We took 24 hour Holter monitoring by Del Mar Avionic tape recorder. All Holter tapes were analyzed with use of Model 563 Stratascan Holter Analysis System. We computed power spectra on each 256 sec segment of each hour during 24 hour recording. So, RR interval, SD of RR interval by time domain, and LF, HF, LF/HF ratio, Total PSD by frequency domain were measured. RESULTS: In congestive heart failure, nocturnal HF peak and diurnal variation of LF/HF ratio was decreased relative to healthy subjects. Nocturnal HF peak in old myocardial infarction was not visualized. All of LF, HF and Total PSD in congestive heart failure and old myocardial infarction patients relative to healthy subjects. CONCLUSION: On heart rate variability analysis using by 24 hour Holter monitoring, abnormal autonomic nervous activity was demonstrated in congestive heart failure and old myocardial infarction patients relative to healthy subjects.

OBJECTIVE: Congenital bilateral perisylvian syndrome (CBPS) has been defined as a characteristic malformative perisylvian polymicrogyria (PMG) in patients with clinical symptoms of pseudobulbar palsy and epileptic seizures. For the present study, we investigate clinicopathologic features of CBPS associated with timing of lesion formation. METHODS: Clinicopathologic features of CBPS from 6 patients with surgical resection of the cerebral lesions due to medically intractable seizures were studied. RESULTS: Seizure onset ranged from 1 to 10years (average 6.7years) of age, and average duration of seizure was 23years. All had complex partial seizures, and two patients had additional tonic clonic seizures. Magnetic resonance (MR) images showed polymicrogyria, atropic gyri with gliosis. In the histopathologic examination, the cortical lesions revealed features of ulegyria ; atrophic and sclerotic gyri, laminar loss of neurons, extensive lobular gliosis throughout the gray and white matter, neuronoglial nodule formation, and many amyloid bodies. Unlayered or four-layered PMG was not identified. CONCLUSION: Above data suggest that CBPS might be caused by ulegyria resulting from developmental cortical defect during early fetal stage or acquired hypoxic/ischemic injury in prenatal or postnatal life.
