The purpose of this study was to evaluate the propriety of making use of light-cured resin base in indirect bracket bonding technique by study of shear bond strength and failure patterns according to the material of resin base. Metal brackets were bonded to the stone models of specimens involving bovine lower incisor with chemical-cured(Excel), light-cured(light-Bond)and thermal-cured(Therma-Cure)resin. They were transferred to the specimens and bonded using sealant. The shear bond strength was tested on Instron. After bracket removal, the bracket base was examined and assessed with the adhesive remnant index(ARI), The result were as follows: 1. No significant differences in shear bond strength were found among the three groups(P>0.05). 2. No significant differences in ARI score were found among the three groups(P>0.05). The above results suggest that light-cured resin base in addition to chemical-cured and thermal-cured resin bases is useful in the indirect bonding technique.

In this study, the authers have investigated a true appreciation on the importance and the actual conditions of utilization of cytologic examination in gynecologic services with 3 step, that is, in 1 step the importance of cytologic examination in gynecologic services has been investigated from the results of 4,024 female of cytologic examination, in 2 step the actual conditions of utilization of cytologic examination have been investigated from 60 medical institutes through questionaire, and in 3 step the more detailed subjects of cytologic examination in gynecologic services have been investigated from 3 medical institutes selected randomly, such an investigations were done to make the programs of improvement in order to promote the activation of gynecologic medical services that shall be able to decrease occurrence of uterine cervical cancer, which is still the most prevalent cancer in korean female, and to make those on effective diagnosis and treatment activaton that shall be able to increase the income of medical institutes. The programs of improvement according to conclusions obtained from investigations like these were summarized as the following. 1. Program to activate positively cytologic examination It was well known that good correlation was noted between number of cytologic examination and those of histologic examination, those of gynecology procedures, and those of gynecologic surgeries. But it was a fact that a most of gynecology board certified physicians and physicians, and medical institutes have not utilized actively cytologic examination in gynecologic practice. Therefore all of married woman should be had politically cytologic examination at regular intervals in order to prevent and detect early uterine cervical cancer. 2. Program to establish exclusively responsible managed systems Managed systems that are exclusively responsible for cytologic examination should be established in order to have examination at regular intervals exactly(six months). 3. Program to utilize correctly the current medical insurance regulations about medical treatment charges The medical charges of cytologic exmination should be applied correctly to the current medical insurance regulations about medical treatment charges in order to increase the income of medical institutes. Because the medical charges of cytologic examination for the levels of medical check up and preventive medicin exception cancer or clinically suspicious cancer diagnosed by physicians is applicable to general medical treatment charges under the current medical insurance regulations. 4. Program to utilize reasonable diagnostic system in cytologic examination. Since certificated technologist screen first thing many microscopic slides for cytologic examination, lastly gynecologic board should make a final diagnosis on only abnormal slides. It is reasonable diagnostic system that can observe more microscopic slides, decrease misdiagnosis and high personnel expenses, and increase income in cytologic examination. Consequently it is necerssary to establish reasonable diagnostic system. 5. Program in order to promote the efficiency of the following examination and treatment system for patients to whom abnormal cell were detected. The following examination and treatment system that were corresponded with diagnosis, and automated and standardized system from receipt to gynecologic practice should be established to offer patients ease and trust, and also medical institutes the more income through the activation of gynecologic practice. Finally, the authers think that it is very important that cytologic examination should be included in routine gynecologic practice.

Mucormycosis is an opportunistic fungal infection caused by the mucorales, which consist of the Rhizophus, Absidia, Mortierella, and Mucor. The diverse clinical forms of mucormycosis can be categorized as rhinocerebral, pulmonary, disseminated, gastrointestinal, cutaneous and miscellaneous. Although it can cause disease in healthy people, it most commonly affects patients who are diabetic or immunosup-pressed. Rarely, mucormycosis develops confined to the subcutaneous tissue. We experienced a case of cutaneous mucormycosis developed in a well-controlled diabetic patient who had previously injected foreign material on her face for an aesthetic purpose at the behest of an unlicensed physician. The patient had tissue necrosis and purulent discharge on her left cheek. Following histologic examination, we diagnosed the condition as cutaneous mucormycosis and treated it by wide excision combined with amphotericin B therapy. The disease was cured without any significant sequelae within 6 months of follow up. Cutaneous mucormycosis is rarely reported but it can cause facial deformity due to tissue necrosis, so that early diagnosis and appropriate treatment are important. Currently, foreign material injection for aesthetic purposes is still performed by unlicensed physicians. We present a case report concluding that one should consider the possibility of fungal infection in skin lesion in diabetic or other immunosup-pressed patients. We also emphasize the seriousness of illegal injection of foreign material.

Objects : Recent studies of psychosocial adjustment after hospitalization have found that the combination of maintenance antipsychotic drug treatment and psychosocial treatment including psychoeducational program are highly predictive of social rehabilitation and reduction of subsequent relapse. Two groups of patients with refractory chronic schizophrenia were preliminarily compared to determine the effect of a psychosocial treatment program on the quality of life in refractory chronic schizophrenics in an open comparative trial. Methods : One group(N=11) was assigned to approximately six months of the psychosocial treatment program(including psychoeducation program and activity program such as interpersonal relationship program, social skill training, self management program, outings, etc), in a group format, twice a week and a fixed maintenance dosage of clozapine ; while scale(QLS) was used to provide an objective measure of changes in patient's psychosocial functioning and a general assessment of psychopathology was made using the Brief Psychiatric Rating Scale(BPRS). Results : Both BPRS total positive score and the QLS total score, especially in the intrapsychic foundation factor of the scale showed a statistically significant improvement in the psychosocial treatment group. But there was no significant change in both BPRS and QLS scores over a 6-month period in the non-psychosocial treatment group. A significant negative correlation was found between the negative symptom and changes of QLS total, instrumental role and common object and activities scores respectively after receiving a 6-month of the psychosocial treatment program. Conclusion : These results suggest that a psychosocial treatment program including the integration of psychoeducation and a skill training oriented activity program serve as an outpatient treatment modality to improve the quality of the life in refractory chronic schizophrenia. To further clarify the effect of psychosocial treatment in chronic schizophrenia, a randomized trial should be done.

Mycoplasma hominis was isolated from a Bartholin's gland abscess 70 years ago, and ureaplasmas were isolated from the genital tract about 20 years later. Subsequently, reports incriminating mycoplasmas in the known adverse outcomes of pregnancy have been reported. Without doubt these genital mycoplasmas are able to invoke an inflammatory response and take part in the cascade of events that culminate in preterm birth. Amniotic fluid infection results in considerable pregnancy wastage in the pregnancy. In these cases Gram-positive organisms, especially group B streptococcus and Streptococcus viridans were the most common pathogens isolated. In our case, the patient has fever and vaginal discharge at 14+4 weeks gestation and two days after intrauterine fetal death was seen. The vaginal culture and sensitivity shown Mycoplasma hominis and Vihdans streptococcus. We experienced a case of Mycoplasma hominis and Viridans streptococcus infection in a patient with intrautehne fetal death and report with a brief review of literatures.
