BACKGROUND: It has been known that androgenetic alopecia in both male and female is due to the role of the androgen hormone in the hair follicle, but the level of the androgen hormone in the plasma is controversial in relation with the development of the alopecia. OBJECTIVE: We have tried the clarify if there is any or no difference in the plasma levels of the hormones between the normal female and the patient with alopecia, because the range of the plasma DHEA-S and total testosterone in the normal female is very wide. METHODS: Plasma levels if the hormones were examined in 22 patients with female androgenetic alopecia and 20 normal females. RESULTS: 1. In DHEA-S, 21(95.5%) aut of 22 female androgenetic alopecia patients were in the normal range while 20(100%) of the 20 normal females were all within the normal range. However the mean value of the hormone(88.89+101.41 g/dl) in the patient group was significantly higher than that(82.18+44.03 g/dl) of the normal group(p<0.05). 2. In total testosterone, 17(94.4%) out of the 18 patents were in the normal range while 20 (100%) of 20 normal females were all within the normal range. However the mean value of the hormone(0.22+0.20ng/ml) in the patient group was significantly higher than that(0.08+0.09ng/ml) of the normal group(p<0.05). 3. As for distribution of DIEA S according to the age, the value of the patient group was higher than that of the normal group in all age groups studied. In the distribution of total testosterone according to age, there was no difference between the normal and the patient in the twenties. After the twenties, the testosterone levels were higher in the patients than the normal females. CONCLUSION: There were significant differences in mean values of plasma DHEA-S and total testosterone between the patients and the normal females although individuals in both groups were largely wit,hin normal range of the hormones.

BACKGROUND: Intracellular calcium overload is a common final feature of the ischemic-reperfused heart and mediates the genesis of irreversible cell damage. Reactive oxygen medabolites have been known to play and important role as toxic mediators in myocardial injuries resulting from ischemia and reperfusion. In order to investigate the mechanism of intracellular calcium accumulation in the ischemic-reperfused myocardium, the present study observed the possible contribution of the reactive oxygen metabolite to the calcium transport of cardiac mitochondria. METHODS: Mitochondrial were isolated from rabbit hearts. The effects of a reactive oxygen metabolite, H2O2 on calcium uptake and release, redox states of endogenous pyridine nucleotides and glutathiones of mitochondria respiring with succinate were observed. Calcium uptake and release were monitored by dual-wave length spectrophotometer using a calcium indicator, arsenaze III. Contents and redox states of pyridine nucleotides and glutathiones were measured by enzymatic methods using spectrofluorometer and HPLC. RESULTS: Hydrogen peroxide(10-500microM) promoted calcium release dose-dependently from CA++-preloaded mitochondria, but did not affect the mitochondrial calcium uptake. The H2O2-induced calcium release was accompanied by simultaneous oxidation of the pyridine nucleotides and decrease in the content of the reduced form of glutathione(GSH). When mitochondria were treated with BCNU(N,N=bis(2-chloroethyl)-N-nitrosourea) to inhibit glutathione reductase and so as to reduce the GSH content, there were no increase in calcium release from the mitochondria. These results may indicate that H2O2 increases the permeability of cardiac mitochondrial membrane to calcium in association with the changes in redox state of endogenous pyridine nucleotides, but not with that of glutathiones. CONCLUSION: It is suggested that the reactive oxygen metabolites induce the release of calcium from mitochondria by altering the redox state of pyridine nucleotides, and it may partly be involved in the elevation of cytosolic calcium concentration in the ischemic-reperfused myocardial cells.

Rapid identification of Mycobacterium spp. isolated from patients is important with increased isolation of mycobacteria other than tubercle bacilli (MOTT). DNA-DNA hybridization with streptavidin-peroxidase and tetramethylbenzidine (TMB) color reaction method was recognized as a useful tool for identification of various species of mycobacteria. In this study, optimum condition of the test was determined. The optimal concentrations of tetramethylbenzidine dihydrochloride and hydrogen peroxide for streptavidin-horseradish peroxidase were 0.3-0.6 ug/ ml and 0.16 mM, respectively. The TMB stock solution was stable when prepared in methanol and the dilution of TBM stock solution in 10 mM sodium citrate-10 mM EDTA solution (pH 5.0) gave highest peroxidase-TMB activity. The suitable composition of hybridization solution consisted of 2 x SSC, 10% dextran sulfate, 50 ug/ml salmon DNA, 5 x Denhardt's solution, and 50% formamide. The 5-minute heating at 100C of test DNA prior to photobiotin labeling significantly increased the reaction. In conclusion, DNA-DNA hybridization method with streptavidin-peroxidase and TMB color reaction method may be useful for rapid identification of Mycobacterium spp. isolated from patients.

The purpose of our study is to evaluate the visual, refractive and IOP results following combined small incision phacoemulsification, foldable lens implantation, and fornix based trabeculectomy with Mitomycin-C. Seventy-six eyes of 64 patients with cataract and glaucoma had undergone the combined procedure. Minimal follow-up period was 6 months(mean 12.8+/-4.8 months). All the eyes that were free of preexisting macular disease and endstage glaucomatous optic nerve damage demonstated significant improvement in visual acuity. Postoperative astigmatisn was negligible(-0.41diopters). The average IOP reduction was 7.7mmHg. Functioning filtrating bleb persisted in 76.3% of the eyes. Complications with this method were not significant compared with other studies reporting the combined procedure. The small incison phacotrabeculectomy with mitomycin-C technique that we describe appears to be effective in early restoration of visual acuity and reduction of IOP without significant complications.

PURPOSE: The committee on trauma of the american college of surgeons, in its manual resources for optimal care of the injured patients involved in falls from less than 20 feet need not be taken to trauma centers. Because triage criteria dictate less urgency for low-level falls, this classification scheme has demerits for early detection and treatment of serious problems in the emergency room. METHODS: A prospective analysis was conducted of 182 patients treated for fall-related trauma from June 2003 to March 2004. Falls were classified as group A (<3 m), group B (> or =3 m, <6 m), and group C (> or =6 m). Collected data included the patient's age, gender, site and height of fall, surface fallen upon, body area of first impact, body regions of injuries, Glasgow Coma Scale (GCS), Revised Trauma Score (RTS), and Injury Severity Score (ISS). RESULTS: The 182 patients were classified as group A (105) 57.7%, group B (61) 33.5%, and group C (16) 8.8%. There was a weak positive correlation between the height of fall and the patients'ISS in the three groups (p<0.001). There were significant differences in GCS (p=0.017), RTS (p=0.034), and ISS (p=0.007) between group A and B. In cases that the head was the initial impact area of the body, the GCS (p<0.001) and the RTS (p=0.002) were lower, but the ISS (p<0.001) was higher than it was for other type of injuries. Hard surfaces as an impact surface type, had an influence on the GCS (p<0.001) and the ISS (p=0.025). CONCLUSION: To simply categorize patients who fall over 6 meters as severely injured patients doesn't have much meaning, and though patients may have fallen less than 6 meters, they should be categorized by using the dynamics (impact surface type, initial body-impact area) of their fall.

Tuberculous arthritis on the sternoclavicular joint is an uncommon disease and a delayed diagnosis can be due to the obscure clinical symptoms. We should suspect tuberculous arthritis in patients with slowly progressive pain, swelling, mild fever and a previous history of tuberculosis. Early diagnosis is important through conducting a thorough physical examination and performing laboratory tests and radiologic study. Tuberculous arthritis on the sternoclavicular joint should be treated with a combination of systemic antituberculous agents and thorough surgical debridement in marked damaged joints. When performing this operation, it is important not only to minimized the injury of the costoclavicular ligament, but also to avoid injury to the surrounding the vital structures such as the mediastinum and pleura after aggressive resection or radical debridement. We describe here 2 cases of the tuberculous arthritis on the sternoclavicular joint: one case had a good result after surgical debridement with using an anti-tuberculous agent, and the other had fatal complications such as mediastinal abscess and pleural effusion after the operation.

Neuromas are hyperplasia of axons and associated nerve sheath cells. Cutaneous neuromas are uncommon. Three kinds of true neuromas exist in the skin and mucous membranes: traumatic neuromas, solitary palisaded encapsulated neuromas, and multiple mucosal neuromas. Traumatic neuromas are usually solitary, skin-colored or pink, firm papules or nodules at the sites of scars following local trauma. A 2-year-old male patient presented a solitary rice grain sized, skin-colored painful and tender polypoid papule on the left 2nd finger. The lesion was superimposed on a small linear scar. The patient had taken a trauma by a broken piece of glass about one month before the development of the neuroma. We report a case of traumatic neuroma with a review of the literature.
