The purpose of this study was to investigate the gaps of bone-acetabular component interface, the initial mechanical stability and the effects of adjuvant screw fixation in the press-fitted two different shaped porous-coated acetabular components. Semi-hemispherical Harris-Galante II cup and full hemispherical Trilogy cup were press-fitted with or without adjuvant screw fixation in 40 bovine femur. The gaps of bone-implant interface were measured in each radiography of all specimen and axial compression tests and rotational stability tests were performed using servohydraulic tension-compression machine. There was significantly smaller gap at polar 1/3 region in the specimen implanted with Trilogy cup. But the adjuvant screw fixation did not affect the amount of gap. There was no significant statistical difference in axial load and rotational stability test in each situations of fixation. This study demonstrates that the initial mechanical stability is not influenced by the shape of semi-hemispherical Harris-Galante II cup and full hemispherical Trilogy cup and also independent of adjuvant screw fixation. But smaller gap of Trilogy cup at the polar 1/3 region indicates the possibility that less amout of wear debris of polyethylene or metal will be deposited and therefore less osteolysis or cup loosening will occur, but this hypothesis should be confirmed by the long-term clinical follow-up.

The characterization of genetic variation at the level of DNA has generated significant advances in gene mapping and disease diagnosis, and forensic identification of individuals. It is now possible to identify individual DNA from various tissue specimens, like hair, using the PCR and oligonucleotide probes. To date, however, the number of hairs needed, the preservation conditions, and the kinds of hair suitable for DNA extraction have not been well known. We performed DNA extraction using hairs from different body sites, using different numbers of hairs, under various different preservation conditions to investigate the acquisition conditions of DNA data from hair using PCR and specific HLA-DQA probe. HLA-DQA genotyping of DNA extracted from peripheral blood was performed to compare the results of hair and blood HLA-DQA genotyping from individuals. The results are as follows: 1) The concentration of DNA extracted from a single strand of hair is 5.23+/-0.54 g/ml. It is possible to extract sufficient DNA for HLA-DQA genotyping from a single strand of hair. 2) DNA concentration is different according to body site. Concentrations are 7.01+/-0.33 g/ml in scalp hair, 6.28+/-0.29 g/ml in axillary hair, and 6.10+0.24 microgram/ml in pubic hair. 3) There is no difference between the electrophortic bands resulting from DNA extracted from the hair of an individual preserved under different conditions, such as room temperature, exposure to sunlight, exposure to low temperature (+4degrees C), or exposure to moisture. 4) There is no difference between the electrophoretic bands resulting from DNA extracted from hair of a single individual preserved for different lengths of time. 5) In an individual, the HLA-DQA genotype obtained from peripheral blood is identical to that obtained from hair. Even though the amout of DNA obtained from hair is limited, it is possible to identify the HLA-DQA genotype of an individual using a single strand of hair. This requires adequate extraction of DNA for PCR analysis using an allele specific probe. We believe that HLA-DQA genotyping using the PCR method on DNA extracted from hair is useful for disease diagnosis and forensic science.

Tsutsugamushi disease is an acute febrile disease caused by Rickettsia tsutsugamushi, and which has been reported with increasing frequency thorough the nation since 1986. We experienced 21 cases of Tsutsugamushi Disease diagnosed with serologic test occurring in Taegu city and Kyungpook province during October-November, 1989. The results of survey are as follow. 1) Of 21 cases, 12 (57%) were males and 9 (43%) were females, and the peak incidence was the 4th decade. 2) The outbreak was in October to November and the peak incidence was in October. 3) The most frequent symptoms were fever and chill (100%), myalgia (95%), headache (90%), Eschar and rash were observed in 18 patients (86%) and the eschar was detected in all over the body, especially thorax (33%) and lower extremity (22%). 4) Laboratory features were SGOT elevation (83%), SGPT elevation (61%), LDH elevation (67%), leukocytosis (38%). 5) Indirect immunofluorescent antibody test was done in 18 patients and the antibody titer was above 1:320 in all patients. 6) The chloramphenicol, tetracycline or doxycycline regimens were very effective and mean duration of defervescence from initiation of therapy was 1.3 days. 7) The complication such as meningitis or shock, was not seen.

Avulsion injury of the flexor digitorum profundus tendon from distal phalanx is considered as a rare injury. Accrording to the classification by Leddy and Pacter, this case is Type III, which is a large bony fragment retained by the tendon. The distal pulley prevents retraction beyond the middle phalanx. We are reporting a case with brief review of literatures.

BACKGROUND: The HMG-CoA reductase inhibitor is the most powerful cholesterol lowering drug and lovastatin, simvastatin and pravastatin are used clinically. We studied the efficacy and side effects of pravastatin monotherapy in patients with hypercholesterolemia(type IIa or IIb). METHODS: Patients who showed 12-hours fasting serum total cholesterol level more than 240mg% were enrolled to diet therapy. After 4weeks of diet therapy, serum lipid profiles were checked and the drug therapy was considered according to NCEP guidelines. The pravastatin 5mg po bid was administrated and the patients had regular follow-up every 2weeks for 8week. RESULTS: The total study population was 20 patients and the mean age of them was 55 years old (55+/-18, M : F=6 : 14). There were a few side effects in 5% of study patients and no patient discontinued pravastatin due to side effects.The side effect was G-I trouble and there were not other side effects. Serum CK was elevated in only one patient but the elevation was mild(less than 3 times) and transient. The LFT, serum uric acid, BUN and creatinine level did not show any significant changes during therapy. Among lipid profiles, total cholesterol, LDL-cholesterol and apolipoprotein B level showed significant reduction after therapy and the maximum reduction was achieved after 2week of therapy. The mean reduction was 20%, 33% and 23% respectively. HDL-cholesterol and apolipoprotein A1 11% and 17% respectively. The triglyceride level did not show any changes during therapy but in one type IIb patient, the triglyceride level decreased significantly. CONCLUSIONS: The pravastatin is effective and safe in patients with hypercholesterolemia.

The May-Hegglin anomaly is a rare autosomal dominant trait characterized by platelet abnormalities in the peripheral blood and large (up to 5mu) pale blue staining inclusions in the cytoplasm of neutrophils, eosinophils, basophils, and monocytes. We experienced a case of May-Hegglin anomaly in a 7 year old male and another case out of his family. His initial complaints at the admission were petechiae and intermittent epistaxis. Diagnosis was confirmed by peripheral blood smear and family study. We report the case with brief review of related literature.

PURPOSE: To determine the efficacy of CarnitilR (acetylcarnitine, Hanmi, Korea) therapy in idiopathic oligoasthenospermic men. MATERIALS AND METHODS: Forty-four subfertile men with abnormal semen parameters were treated between March, 2003 and March, 2004 with 3 g of CarnitilR daily for 3 months. Changes in semen parameters were evaluated 3 months after this therapy. RESULTS: The mean age was 34.2 years and the mean follow-up duration was 3.7 months. In asthenospemic patients (n=28), semen analysis before and after CarnitilR treatment showed an increase in volume (2.64+/-1.65 ml vs. 3.10+/-1.60 ml), motility (35.1+/-17.7% vs. 45.9+/-20.4%) and viability (51.4+/-20.3% vs. 59.3+/-13.6%) respectively. In oligoasthenospermic patients (n=16), semen analysis before and after CarnitilR treatment showed an increase in sperm count (10.7+/-54.4 million/ml vs. 38.4+/-32.5 million/ml) respectively. CONCLUSIONS: These results suggested that in idiopathic oligoasthenospermic men the empirical medical therapy with acetylcarnitine may be considered as primary treatment.
