The ectomycorrhizal roots were collected from the soils around the bases of basidiocarps of the four edible mushrooms in the stands of Pinus densiflora or Querus acutissima communities (Mt. Wol-Ak in Eastern Chung-Puk): The basidiocarps of Tricholoma matsutake (TM), Sarcodon asparatus (SA), S. imbricatum (SI), and Polyozellus multiplex (PM) are usually collected. The ectomycorrhizal roots of TM, PM and SI were related to the roots of P. densiflora, but the other to the roots of Q. acutissima in Korea. Particularly, the basidiocarps of PM were collected in the mixed stand of both P. densiflora and Q. acutissima. The morphologies of the ectomycorrhizal roots were observed to be the yellowish brown coral (dichromatous) or pyramid types in the roots of the pine, but dark brown un-branched sticks (roots) in the ends of ectomycorrhizal roots of Querus plants. The un-branched roots were covered with the dark mycelia (rhizomorph) around them. Therefore, the ectomyorrhizal roots of PM were observed to have two kinds of types; The single blackish un-branched roots were observed to be attached to the yellowish coral type roots. The bundles of TM mycelia were filled with cortical cells (in the roots of P. densiflora), but the mycelia of the other fungi (Aphylloporales) were massed between the cortical cells of P. densiflora or Q. acutissima. Their anatomical and gross features were considered to be simailar but very important in the ectomycorrhizal roots for these edible mushrooms.

Purpose:
This study examined the patient-reported outcome scores at mid-term follow-up after arthroscopic labral preservation in patients with borderline hip dysplasia.
Materials and Methods:
Data were collected retrospectively from patients who underwent arthroscopic labral preservation. Among the 61 patients classified with hip dysplasia, patients with arthritis beyond Tönnis grade II were excluded, Patients with subchondral bony exposure were excluded even if they had arthritis of Tönnis grade I. Forty-two patients with borderline hip dysplasia were enrolled among patients whose lateral center edge angle (LCEA) was between 18° and 25°. The PRO scores including the modified Harris hip score (mHHS), hip outcome score activities of daily living (HOS-ADL), hip outcome score sport-specific subscale (HOS-SSS) and visual analog scale (VAS), were collected and compared preoperatively, and then at one year and a minimum of five years after surgery.
Results:
The mean preoperative LCEA and Tönnis angle were 20.9° (range, 18° to 25°) and 6.3° (range, 0° to 18°), respectively. The mean follow-up was 64.8 (range, 60 to 84) months. The mean mHHS increased from 73.5 before surgery to 86.2 in the fifth year after surgery (p<0.01), the mean HOS-ADL from 70.5% before surgery to 84.9% in the fifth year after surgery (p<0.01), and the mean HOS-SSS from 51.4 before surgery to 69.4 in the fifth year after surgery (p<0.01). The mean VAS score improved from 6.3 before surgery to 1.5 in the fifth year after surgery (p<0.01).
Conclusion
Arthroscopic labral preservation performed in appropriately selected patients with borderline dysplasia showed good results at mid-term follow-up. In borderline hip dysplasia without the progress of osteoarthritis and subchondral bone exposure, arthroscopic labral preservation may be considered a good and less invasive option.
6.A STUDY ON THE ANTIMICROBIAL SUSCEPTIBILITY OF ORAL MICROFLORA IN CHILDREN SUSCEPTIBLE TO INFECTIVE ENDOCARDITIS.

The present study has been performed to evaluate 20 cardiopathy children and 20 healthy children's oral micorbes at the point of antimicrobial susceptibilities for antimicrobial prophylaxis to prevent bacterial endocarditis. The results were as follows: 1. Both groups had similar oral microbes. 2. The antimicrobial susceptibility of S. viridans were: Penicillin< Oxacillin< Ampicillin< Cephalothin< Erythromycin< Clindamycin< Gentamicin< Ciprofloxacin< Vancomycin=Imipenem. The cardiopathy group was slightly lower antimicrobial susceptibility rates than healthy group. 3. The antimicrobial susceptibility of Neisseriaceae were: Clindamycin< Erythromycin< Vancomycin< Penicillin< Gentamicin< Cephalothin< Ciprofloxacin< Imipenem. The antibiotics of bacterial endocarditis antibiotic prophylaxis regimens for dental procedures according to the American Heart Association were generally lower antimicrobial susceptibilities, so they were considered inadequate for the first selective antibiotics and Imipemem was best suitable antimicrobials. Conclusively, when choose antimicrobials for treatment or antimicrobial prophylaxsis for bacterial endocarditis, surveillant culture must be performed to evaluated personal antimicrobial susceptibilities of intraoral microbes for proper antimicrobial choice for dental procedures.

Furfurol(Furfudol), a new anthelmintics, was administered to 7 adults and 21 children (6-12 years old) in total amounts of 15.6 mg(base) for 1 to 3 days. It has proven to be effective against hookworms. The anthelmintic effect against hookworms with a single dose of 15.6 mg of furfurol was similar to that of a single dose of 2.5 gm of bephenium hydroxynaphthoate. However, when a total of 15.6 mg of the base was given to both children and adult, the side reactions were so mild that the drug can be administered for therapeutic regimens in mass treatment. Minor abdominal discomfort was the only common side effect. This is the primary advantage of furfurol as compared with bephenium hydroxynaphthoate. These results have indicated that furfurol is safe in therapeutic dosage and is an effective agent to treat patients infected with hookworms.

10.A clinical study on ludwig's angina.
Journal of the Korean Association of Oral and Maxillofacial Surgeons 1998;24(1):68-74
This is a retrospective study on the Ludwig's angina patients treated in Dept of Oral and Maxillofacial Surgery of Pusan National University Hospital for the period of Jan. 1985 to March 1996. The used materials of this study were 30 in total, including 18 male patients, 12 female patients. The author analyzed the distribution and incidence of sex, age, etiologic factor, pus culture, involved systemic disease, treatment methods, mortality rate. The results were as follows; 1. The incidences was higher in sixth decades(26.7%) and prevalent in male. 2. The most cause was odontogenic(83.3%) and in 15 cases(50%), the symptom aggravated after dental treatment. 3. The causative organism isolated from pus culture were Streptococci (40.7%), Staphylococci(22.2%), Bacteroid(14.8%), Candida(11.1%), Pseudomonas(3.7%), Pneumococci(3.7%), Salmonella(3.7%). 4. The patients with systemic disease were 66.7%, involved disease were DM(25%), malnutrition(22.7%), rheumatoid arthritis(11.4%), pulmonary disease(11.4%), hypertension(11.4%). 5. In all patients, surgical I&D was done, and 5 cases(16.7%) required tracheostomy. 6. In all patients, we used combination antibiotics, and the most commonly used antibiotics in the treatment were combination of Penicillin, Cephalosporin and Aminiglycoside(46.7%), and combination of Cephalosporin, Aminiglycoside and Metronidazole(30%). 7. The mortality rate was 6.7%.
