The purpose of this study was to observe mandibular condyle shape and position in an asymptomatic population. In o rder to carry out this study, 142 temporomandibular joints in 71 adults(35 males, 36 females), who were asymptomatic for temporomandibular joint disorders and had no history of prosthodontic or orthodontic treatments, were selected, and rad iographed using the Accurd-200 head holder(Denar Co., U.S.A.) for lateral individualized corrected tomograms. Mandibular condyles were classified morphologically and evaluated in positional relationships with articular fossae and articular eminences at centric occlusiohn and 1 inch mouth opening. The obtained results were as follows : 1. In the classification of mandibular condyle shape, the convex type was more prevalent in trascranial radiograms and tomograms taken at medial, central, and lateral locations. 2. In the mandibular condyle position at centric occlusion, the mandibular condyles were palced posterior to the center of articular fossae in trascranial radiograns and anterior to the center of articular fossae in tomograns taken at medi al, central, and lateral locations. 3. In the mandibular condyle position in right and left TMJs at centric occlusion, the mandibular condyles were placed bilateral asymmetric relationships to the articular fossae in trascranial radiograms and tomograms taken at medial, cent ral, and lateral location, 4. In the mandibular condyle position at 1 inch mouth opening, the mandibular condyles were placed anterior to the arti cular eminences in trascranial radiogramas and tomograms taken at central location and posterior to the articular eminen ces in tomograms taken at medial and lateral locations.

A 46 years old male patient had visited to our Ophthalmology department due to abrupt onset of decreased visual acuity in his left eye. He had taken an operation for correction of high myopic astigmatism on both eyes 23 years ago in Japan by Dr. Sato. His visual acuity was: (R)0.3(0.7 x Sph. + 0.75D. = Cyl. - 5.50D.A10 degrees) (L)0.15(0.2 x Sph. - 2.50D. = Cyl. - 2.25D. A180 degrees). On slit lamp examination. hoth cornea had 3mm. (length) radiated linear scars in a number about 50 resulted from myopic operation. In his left cornea, several small vesicles and mild corneal central opacity were observed. We have diagnosed this symptom as artificial corneal endothelial Dystrophy.

Concha bullosa is one of the most common anatomical variations detected in the paransal sinus and nasal cavity. In this study, the incidence of concha bullosa and the relationship between the size of concha bullosa and the degree of the paranasal sinus lesion is to be inquired. This study was based on 232 patients who visited our outpatient department with rhinological symptoms suspected with chronic sinusitis who went under OMU CT. Based on OMU CT reviews, the grade of concha bullosa was divided into four stages and the paransal sinus lesion was classified into 5 stages. The prevalence rate of concha bullosa was 36.2% with 14.6% bilateral and 21.6% unilateral. The accompanying incidence of concha bullosa in patients with no sinus disease was 20.2% and 26.8% in sinusitis patients, with no significant statistical difference between the two groups. Merely, a higher prevalence rate was seen in patients with paranasal sinus lesions localized in the OMU. However, for a more accurate result as of concha bullosa functioning as an etiological factor of sinusitis, a random population based study will be necessary. Also, it has been noticed that septal deviation, in all anatomical variations, most commonly occurs in patients with concha bullosa.

This study was designed to develop the life moking cessation program with multidisciplinary approach using the Bandura's theory of self-efficacy and confirm the effect of it on the self-efficacy and smoking amount in college students. For this purpose non-equivalent control group, pretest-posttest design was used. The participating subjects in this study were 46 male college freshmen, 23 in experimental and 23 in control group. The experimental group received the 8 sessions of lecture and small group discussions for 4 weeks and a telephone coaching program for a period of 8 weeks. The control group received 5 sessions of lecture without further treatments. The data was collected from March 15 to June 11, 1999, and analysed by SAS/PC program with X2 test, simple t, paired t test. The results were as follows. 1. The score of self-efficacy was significantly increased over time in the experimental group than those of the control group. 2. The amount of urine cotinine was decreased over time in the experimental group, number of cigarettes smoked a day were significantly decreased, and they were significantly less than those of the control group. In conclusion it was found that the Life Smoking Cessation Program with Multidisciplinary Approach was an effective nursing intervention for increasing self efficacy and reducing the amount of smoking in male college students. Therefore, future smoking cessation programs should always consider the concept of self-efficacy and ways to positively reinforce it.

To evaluate the etiology and treatment of options in patients with hemospermia, we retrospectively reviewed 21 patients who had both transrectal ultrasound and MRI and have been followed for more than 6 months after initiation of treatment. Mean age was 40 years (range 20 - 50 years) with duration of infliction being 24 months (range 1 week to 16 years). Among the 14 patients with prostatic cyst, 9 patients underwent transurethral unroofing (TUUR) of cyst. All 9 patients were completely cured, but one patient developed postoperative epididymitis. Among the 6 patients with prostatitis, hemospermia was resolved in 4 patients after mean treatment of 12 weeks with antibiotics. In DES (Diethylstilbestrol) group, 50 % showed resolution of symptoms among 6 patients after 4 weeks of treatment, and two patients complained breast discomfort which were developed after medication. In conclusion, the antibiotic treatment is advisable in hemospermia patients with prostatitis. Prostatic cystic lesion is believed to be a factor in hemospermia, thus TUUR of cyst wall and removal of stone and hematoma in cyst can be a viable option.

BACKGROUND: Hansen's disease is chronic disease, often resulting in musculoskeletal complication such as chronic ulcer, deformity, disability. The aim of this article is to know the present status of prescription of orthosis and to assess the usefulness of orthosis. METHODS: Analysis was done on subjects who had were prescribed orthosis from December, 2007 to November, 2008 at the Clinic of Reserch Center. We have asked the patients questionnaire such as frequency of use of the prescribed orhtosis, the degree of pain reduction and comfortability with orthosis,the cause of disuse of orthosis ,the degree of preventing relapse of ulcer with orthosis, request about prescribed orthosis. RESULTS: The total number who were prescribed orthosis was 173. About 69.4% patients have used orthosis very frequently or nearly at all times. About 83.2% patients said that orthosis had done them good in pain reduction, preventing relapse of ulcer. The major reason of disuse of orthosis was inconvenience of management, not no-helfulness. The major request about orthosis were improvement of quality, imprvement of strength of orthosis, shortening of limitation term of prescription. CONCLUSINON: The prescription of orthosis to Hansen patients with musculoskeletal sequale improve quality of life and is available in preventing relapse of ulcer.

The purpose of this study was to aid in the prediction of tumor cell tolerance to radiotherapy and/or chemotherapy. For this study, cell surviving curves were obtained for human epidermoid carcinoma A-253 cell line using semiautomated MTT assay. 2, 4, 6, 8, 10 Gy were irradiated at a dose rate of 210 cGy/min using 60Co Irradiator ALDORADO 8. After irradiation, A-253 cell lines(2x10(4) cells/ml) were exposed to bleomycin or cisplatin for 1 hour. The viable cells were determined for each radiation dose with/without 2 ug/ml of drug at the 3rd day. And they were compared to control values. The results were obtained as follows: 1. The surviving curve with gentle slope was obtained after irradiation of 2, 4, 6, 8, 10 Gy on A-253 cell line. 2. The cytotoxicity of bleomycin or cisplatin at the concentration of 2 ug/ml was great on A-253 cell line. But, there was no significant difference between the cytotoxicity of bleomycin and that of cisplatin. 3. There were significant differences of surviving fractions after irradiation with 2 ug/ml of bleomycin compared with irradiation only on A-253 cell line. 4. There were significant differences of surviving fractions after irradiation with 2 ug/ml of cisplatin compared with irradiation only on A-253 cell line. 5. There were no significant differences of surviving fractions between the groups of irradiation with bleomycin and the groups of irradiation with cisplatin on A-253 cell line.

Leprosy is disease of skin and peripheral nerve especially. Sequale and disability of musculoskeletal system, especially peripheral extremities (hands and foots) can be developed due to severe and irreversible peripheral nerve damage in leprosy. In leprosy, Skin ulcers can relapse very often and progress to deformity and amputation of hands or foot. We need methods to treat skin ulcer effectively. We have used various therapies such as antibiotics in infectious state, disinfectant, variable wet dressing materials(transparent film, foams, gels&hydrogels, hydrocolloids, calcium alignate), silver dressing, Vacuum Assisted Closure unit, debridement, curettage, surgery to treat skin ulcer in leprosy patients. Sometimes we can treat skin ulcer successfully but, we often encounter ulcer resistant to treat. We need to find and develop methods to treat ulcer successfully. Several researches have reported articles to treat wound successfully using light emitting diode(LED). We tried to treat ulcer in old leprosy patients using LED. We divided ulcers patients into case group(conventional dressing therapy + LED therapy) and control group (only conventional dressing therapy) randomly in out patient department and in ward. This research was carried out from February 2012 to September 2012. Case group and control group have composed of 30 patients respectively. Average age of patients was 74 years old in case group and 69 years old in control group. We have used LED device composed of 700 pieces of diodes emitting 635nm and 500 pieces of diodes emitting 830nm, totally 1200 pieces of diodes. We have observed the size of wounds twice per week in control group and case group. Before treatment average size of wounds was 8509.76mm3 in case group and 8625.33mm3 in control group. P-vale was 0.49. There was no significant difference in case and control group. After treatment average size of wounds was 787.83mm3 in case group and 8074.63mm3 in control group. P-vale was 0.02. There was significant difference in case and control group. After treatment average reduction of size per time was 338.02mm3/day in case group and 26.55mm3/day in control group. P-vale was 0.002. There was significant difference in case and control group. Therefore we have concluded that LED device was effective in wound treatment. Some articles have reported that LED Device have helped to treat wounds in DM ulcer, third degree burn, oral ulcer, skin ulcer in Klippel-Trenaunay syndrome patient, some retinopathy etc. We have concluded that LED of infrared or long visible wavelength light can be used effectively in treatment of wound along with conventional treatment concurrently.

The purpose of this study was to investigate effects of osteoporosis on fracture wound healing in the calcium defi cient rat. To research the experiment some ten-week old Wistar strain rats with approximately 300 gms weight were selected. Then , the rats were divided into two groups: Normal diet group(rats given a normal diet before and after bone fracture) and Low calcium diet group(rats given a low calcium diet before and after bone fracture). Both groups had been provided wit h each diet for three weeks. When the rats became thirteen weeks old, the mandibular angle of rats in both groups was ar tificially fractured for test. The healing of fracture wounds was reviewed by using soft x-ray radiography and 99m Tc-MDP bone scan and also histopathologic examination. The obtained results were as follows : 1. The radiolucency of the fracture site for the Normal diet group started to decrease from the 14th day since the expe riment was made, while the Low calcium diet group began decrease in the radiolucency from the 21st day of the experiment . The radiolucency for the normal diet group disappeared at the 42nd day, but one for the Low calcium diet group disappe ared at the 56th day of the experiment. 2. The highest uptake rate of (99m)Tc-MDP stood at the 14th day of the experiment in the Normal diet group and the Low calium diet group's maximum rate was recorded at the 21st day of the experiment. These both groups were gradual ly experiencing decrease in the uptake rate as the experiment time was going on. However, the uptake rate in the Low cal ium diet group was lower than one in the Normal diet group. 3. For the Normal diet group, the newly formed trabecular, which were similar to one of the surrounding bone, were seen at the 42nd day of the experiment. On the other hand, the Low claium diet group showed at the 56th day of the experimen t that the osteoporotic findings looked weak, irregular trabecular, and also large bone marrow space were observed clear ly. As a result of the above experiment, it is said that the healing of the fracture can be completed for both groups, t he Normal diet group and the Low calium diet group. However, the amount of the newly formed bone wound in the Low calciu m diet group is rather decreased compared to one in the normal diet group and at the same time the healing of the fractu re is delayed in the Low calcium diet group. Consequently, for the successful healing of fracture in osteoporosis, it is considered that the management of the etiologic factors of osteoporosis must be preceded. the more study of calcium met abolism and functions of osteoblast and osteoclast needs to proceed on.
