The purpose of this study is to provide the data for the co-operative treatment of western and oriental hospital. The studies were made a questionnaire to analyze inpatients' awareness on the systems of co-operative treatment and to observe the differences in medical service satisfaction between inpatients who had experienced the co-operative treatment of western and oriental hospital(Group 1) and those who did not (Group 2). The survey was conducted in February 1998, on 250 inpatients who were in a hospital which provided co-operative treatment of western and oriental medicine in Pusan. Korea. The results of this study were disclosed as follows: 54.2% of western hospital inpatients and 90.5% of oriental hospital inpatients suffered from diseases of the nervous system 88.9% of Group 1 and 72.2% of Group 2 believed that the co-operative treatment of western and oriental hospital was more effective in curing diseases of the nervous system. 33.5% or inpatiens in the western hospital and 87.4% of inpatients in the oriental hospital had received the co-operative treatment. In the case of the oriental hospital inpatients who had experienced western treatment, 36.8% received an examination radiologic, 30.7% received a laboratory test, 17.8% received physical therapy, and 14.1% received medication. Whereas, in case of the western hospital inpatients who had experienced oriental treatment, 71.8% received acupuncture, 23.9% received herbal medicine, and 2.8% received oriental medical tests. As to the opinion on the systems of co-operative treatment, 49.6% of Group 1 agreed that 'New medical institutions that adopt the merits of both western and oriental medicine are absolutely necessary.', and 48.9% of Group 1 agreed that 'Since there are strong points and weak points in both western and oriental medicine, partial and gradual introduction of the two systems would be better.' Whereas, 49.6% of Group 2 agreed that the partial and gradual introduction, and 35.7% of Group 2 agreed that the necessity of the new medical institutions. As to the motives for visiting the hospital, the most popular reason for all the inpatients was "others' advice". In the case of Group 1, however, the most popular reason was "the possibility of co-operative treatment". In regards to medical cost, the oriental hospital inpatients felt that their medical cost was too expensive. On the other hand, a smaller percentage of the western hospital inpatients felt that western hospital medical cost were too expensive. And between Group 1 and Group 2, a higher percentage of Group 1 felt that their medical cost was too expensive.

The object of this paper was to investigate the histopatological changes on dog's pulp under cavitation by irradiation of the $CO_2$ laser. The subjects were derived from four dogs, and irradiated 113.23 J/$mm^2$, 283.09 J/$mm^2$, 566.08 J/$mm^2$ in Group I, II, and III respectively. The dogs were sacrificed immediately, 24 hour, 72 hour and 1 week after $CO_2$ laser treatment. For light microscopic examination, routine H-E and PAS stains were employed. For electron microscopic observation, the teeth were fixed in 1% paraformaldehyde and 1% glutaraldehyde, decalcified teeth in 10% EDTA were stained by uranyl acetate and lead citrate. The observation was made with a Hitachi H-500 model electron microscope. The following results were obtained in this study: 1. At the early stage of the experimental sub-groups-immediately, 24 hour, 72 hour samples of Group I, II and III-coagulation necrosis and hyperemia were observed in odontoblastic and subodontoblastic pulpal layer. 2. At the 1 week sub-group of Group I, II, regenerative hyperplasia of the odontoblasts without coagulation necrosis were revealed, in addition to thickened predentin. On he other hand coagulation necrosis and atrophic change accompanying with hyperplasia were found at the 1 week sub-group of Group III. 3. Ultrastructurally, the odontoblasts appeared nuclear degeneration, vacuolar change of cytoplasmic organelles and rupture of plasma membrane at the early stage of the experimental period of all groups. 4. Under spectrohelioscopic examination, regenerative odontobalsts were seen at the 1 week specimens of Group I, II and III. 5. The pulpal response occured at 113-566 J/$mm^2$. The pathologic change of pulp tissue occured at the early experimental period but regeneration of odontoblasts could be seen after 1 week.

The amount of D(-)-lactic acid in fermented dairy products is very important because the rate of metabolism of D(-)-lactic acid is lower than that of L(+)-lactic acid. The purpose of this study was to investigate the optimum condition during fermentation and storage of yogurt for the formation of isomers of lactic acid by Lactobacillus acidophilus NCFM. The production of acid was excellent at $37^{\circ}C$ of fermentation and the ratio of D(-)-lactic acid was also lower than that of other conditions such as $35^{\circ}C{\;}and{\;}40^{\circ}C$. Among shaking and non-shaking treatment under aerobic condition and anaerobic condition, non-shaking treatment under aerobic condition was the best condition at the production of acid and L(+)-lactic acid during fermentation. During storage at low temperature, a larger amount of L(+)-lactic acid was produced than at higer storage temperature.

A mucocele is a thin-walled, bluish, fluctuant swelling occurring just beneath the oral mucosa and filled with mucoid material. It usually results from damage to a salivary gland following which there is extravasation of mucus into the tissues, or occasionally it forms from dilatation of the duct of a salivary gland. The accepted treatment of a mucocele is excision of the sac and the associated minor salivary gland. Use of the $CO_2$ laser in oral surgery has several advantages. It is a very precise means of cutting tissue and causes little adjacent nontarget tissue damage. There is excellent coagulation of small blood vessels and consequently operative hemorrhage is greatly decreased. There is instant sterilization of the operative site, which decreases bacteremia. The operation sites were completely healed without any infection or complication and discomfort from swelling or pain was not noted in all cases throughout the healing process. In addition, following this therapy, there is little contraction or scarring.

The purpose of this study was to evaluate the marginal leakage of glass ionomer cement with different cavosurface margins. 192 class V cavities were prepared on freshly extracted non-carious teeth and glass ionomer cement were inserted according to the manufacturer's instructions. Cavity preparations for this investigation were performed in four groups. The experimental specimens were made by packing the glass ionomer cement (Fuji Ionomer Type II G-C Co. Japan) into the prepared 192 cavities of four groups with different modes: Group I. - The 48 cavities with $90^{\circ}$ butt-joint cavosurface preparation and restored with glass ionomer cement. Group II. - The 48 cavities with butt-joint preparation modified by $135^{\circ}$ beveling the cavosurface in the dentin and restored with glass ionomer cement. Group III. - The 48 cavities with butt-joint preparation modified by cutting a chamfer in the dentin and restored with glass ionomer cement. Group IV. - The same 48 cavities as group I, and overfilled with glass ionomer cement beyond the cavosurface angle. And four groups above described divided into three subgroups by means of conditioning the cavity walls: Control group. - Glass ionomer cement filled in the prepared 64 cavities after being cleaned with a stream of tap water. Phosphoric acid treatment group. - Glass ionomer cement filled in the prepared 64 cavities after being conditioned with a 50% phosphoric acid. Citric acid treatment group. - Glass ionomer cement filled in the prepared 64 cavities after being conditioned with a 50% citric acid. All 192 specimens were immersed in the 2.0% basic fuchsin solution and subjected to thermal stress at one-minute intervals ($4{\pm}2^{\circ}C$ to $60{\pm}2^{\circ}C$) for 70 minutes before exposure to the dye. The specimens were sectioned ecclesiologically through the center of the restorations for different periods of immersion time, 24 hours, 7 days, 14 days 30 days. The sections were examined under a stereoscopic microscope. The results were as follows: 1. The degree of marginal leakage in group II and III was greater than that in group I and IV. 2. The degree of marginal leakage in phosphoric acid treatment group was similar with that in control group. 3. The degree of marginal leakage in citric acid treatment group was less than that in control group. 4. In all groups, the degree of marginal leakage in phosphoric acid treatment group was greater than that in citric acid treatment group. 5. There is no statistical difference of the degree of marginal leakage according to the immersion time in the dye solution.

Objectives : We already reported the effectiveness of this treatment method(electroacupuncture at oculomotor muscles) at the adult and young idiopathic paralytic strabismus patients and Miller-Fisher syndrome. Then I explored the possibility for improvement of the traumatic injury paralytic strabismus case. Methods : I treated the case by using the electroacupuncture at both paralytic lateral rectus muscle lesions. The case was treated almost daily and every treatment was enforced 10 minutes. I use the PG-306 electra-acupuncture products(Suzuki Iryoki Co. Japan) and apply the low consequence wave of 1-8Hz. Results : We gained good results from the case and not observed any sides effect or compliant. So I hope to apply this treatment for traumatic and post-operative nerve injury cases and am sure to make the treatment protocol for them in the future.

Keloids are pathologic fibroproliferative conditions characterized by excessive collagen deposition during wound healing. The pathogenesis of keloids is not fully understood, and current treatment options show variable results. In this case report, the patient developed a keloid after bilateral total thyroidectomy, and was treated with a combination approach using fractional ablative laser systems along with cryotherapy and triamcinolone injection. After seven monthly sessions of combination treatment, the patient presented marked improvement of the scar texture and symptoms. Furthermore, there was no recurrence for up to 2 years. We propose this combination as a safe and effective treatment option for keloid patients.

An approach to the treatment of post-operative pain by the injection of bupivacaine into the pleural space through an intrapleural cathter has been studied. Among 24 thoracotomy patients, bupivacaine was injected only to experimental group[ 12 patients ] when the patient was able to head up for oneself during recovery from anesthesia. The pain and ROM[ range of motion ] scores, respiration rate, PaCO2 level of both experimental and control group were measured at the time of head-up and 30 and 120 minutes thereafter.The scores of pain and ROM of experimental group were significantly[ P value < 0.05 ] decreased in 30 minutes and 120 minutes after bupivacaine injection compared with those of control group but respiration rate and PaCO2 level were not changed significantly. With this result, we can suggest that intrapleural injection of bupivacaine is useful for pain relief following thoracotomy.

The preliminary analysis has been made of 63 Patients who were treated in the Department of Radiation Therapy at Korea University Hospital for the lung cancer from April 1981 to December 1983. The patients were treated via Co-60 teletherapy unit and the doses were 5,400 rad/ 6 week for the curative, $3,600\~4,500\;rad/2\;1/2\;\~3$ week for the Palliative treatment. Thirty two $(32/63=51\%)$ patients have been for curative, $25/63 (40\%)$ were for Palliative, and $6/63 (9\%)$ were for post-operative radiation. A post-radiation treatment, $28/63 (53\%)$ were able to follow from 2 months to 3 yrs. During the follow up, chest X-rays and/or CT scans were taken and $22/27 (81.4\%)$ of patients were responded more than $50\%$ of tumor regression one month following completion of radiation.

Clinical analysis were performed on 247 cases of thoracic trauma, those were admitted & treated at the department of thoracic & cardiovascular surgery,Hanyang University Hospital during the period from Jan,1989 to June,1992. Age distribution of those was from 2 to 80 years old & mean age was 38 years old. The ratio of male to female patient was 186:61 [3:1].This ratio revealed high incidence in male patient. The most common cause of trauma was traffic accident in this series.The modes of injury were as follows: traffic accident 124 cases[50.2%],fall down 52 cases[21.05%], stab wound 47 cases[19.03%] and gun-shut wound 1 case.Ellapse time from accident to admission were 141 cases [57.09%] under 6 hr.Rib fracture were observed in 159 cases[64.37%], hemo or pneumothorax were observed 134 cases[54.25%] of total cases and location distributed Right:Left:Both[74:112:37], in left predominant. Conservative,non-operative treatment were performed in 128 cases and operation[open thoracotomy] 32 cases.Mortality was 1.6%[4 cases] & most common cause of death were due to irreversible shock with brain edema. Conclusively, more evaluation & co-operation of other department were expected treatment & better prognosis.
