Chloramphenicol주사에 의한 좌골신경손상을 유발한 후 Prednisolone을 이용한 약물처치군, 전침군 및 전침과 약물을 병용한 군에서 각각 회복속도를 비교하였다. 정상보행 횟수, pinching을 통한 감각신경의 통감반응,그리고 병리조직소견 등을 죠사한 결과를 요약 하면 다음과 같다. Enrofloxacin, cefazolin, cephalexin, penicillin 등의 좌골신경주위 주사게 서는 신경마비가 관찰되지 않았으나 chloramphenicol을 주사할 경우에는 좌골신경손상으로 인한 편측성 후지마비가 유발되어 knuckling 반응을 보였다. Chloramphenicol을 투여한후 좌골신경손상에 대한 각 처치에서 정상보행 횟수는 8-12주까지는 침술처치군이 약간 중가하 였으나, 처리군간 유의성은 관찰되지 않았다. 실험기간동안 chloramphenicol 에 의한 신경손 상에 대한 각 처치군별 병리조직 소견은 호전양상이 관찰되지 아니하였다.

현재 시판되고 있는 정장용 생균 제제에 함유되어있는 정장 균주의 하나인 Bifidobacterium bifidum은 항결핵제 중 rifampicin에 감수성으로 rifampicin과 병용 투여시 본래의 정장 효과를 기대할 수없다. 따라서, rifampicin에 내성인 돌연변이 균주를 얻기 위해 B. bifidum을 N-methyl-N'-nitro-N-nitrosoguanidine(MNNG)로 처리하여 rifampicin에 내성인 30 종의 균주를 선별하였고, rifampicin에 대한 Minimal Inhibitory Concentration (MIC)를 측정해 본 결과 내성이 1,000 배 이상 상승하였다. 균주 동정을 위하여 fructose-6-phosphate phosphoketolase test를 실시해 본 결과 Bifidobacterium임이 확인되었다. 이들 내성 균주들의 유기산 생산량을 측정하여 그 생산량이 모균주와 가장 유사한 3 종의 균주를 선발하였다. 이들에 대하여 Escherichia coli 생육 억제능을 시험해 본 결과 E. coil 생육 억제능이 모균주와 유사하였다. 또, rifampicin을 함유한 배지에서 돌연변이 균주를 배양시킨 경우 rifampicin이 안정한 상태로 잔존한 것을 알 수 있었다. 이것으로 보아 돌연변이 균주들은 rifampicin을 분해 또는 변형시키는 효소를 생산하지 않는다고 볼 수 있다. 이상의 결과로 본 연구에서 개발한 돌연변이 균주들, 즉 B. bifidum RFRll, RFR21 그리고 RFR61은 rifampicin에 내성이면서 모균주와 동일한 생화학적 특성을 갖는 정장 균주로 여겨진다.

The antihypertensive effect of clonidine administered concurrently with labetalol or metoprolol were studied with spontaneously hypertensive rats (SHR). The changes of heart rate were also observed in the same rats. Every drug was orally administered single dose after prechecking the systolic blood pressure and heart rate of SHR. The blood pressure of SHR in concurrently administered group was more significantly decreased than in alone administered group. The effective and stable decrease of blood pressure was maintained at the group of clonidine with labetalol (0.05+50mg/kg) for 9 hours. The group of clonidine with metoprolol (0.05+100mg/kg) manifested more marked decrease of blood pressure than the group of metoprolol (100mg/kg) alone for 9 hours. The diminishing effect of heart rate was enhanced in group of administering clonidine with labetalol, decreasing the dose of labetalol from 50mg/kg via 25mg/kg to 12.5mg/kg. On the other hand, in the group that clonidine was administered concurrently with metoprolol, the diminishing effect of heart rate was decreased with decreasing doses of metoprolol from 100mg/kg via 50mg/kg to 25mg/kg.

Purpose: This study examined the effectiveness of a hand massage combined with analgesics on pain control in hospice patients with terminal cancer. Methods: This study is a quasi-experimental study with a single group time series design. The study included 25 terminal cancer patients who were admitted to a hospice ward. Each patient's pain level was measured after analgesics use only (control group). When patients complained of pain again, the pain level was assessed after administering a combination of hand massage and analgesics (experimental group). As for the experimental treatment, the participants were provided with oil hand massage on each hand for 5 minutes. Results: The experimental group and the control group showed no significant differences in the changes of pain score (F=0.74, P=0.3939). Conclusion: Although the pain level of the experimental group did not significantly improve compared with the control group, their pain levels tended to be low to begin with. Thus, a complementary utility value of hand massage cannot be completely excluded in terminal cancer patients. Since the pain level significantly changed according to the dosage of analgesic, nurses need more education and research on analgesic drug therapy for terminal cancer patients.

Garre's osteomyelitis is associated with bacterial infection and bone necrosis resulting from obstruction of blood supply. The most common cause for Garre's osteomyelitis is odontogenic infection that originates from periodontal tissue or dental pulp. Subperiosteal abscess may also cause Garre's osteomyelitis in the progress of the infection. Mandible is more often affected than maxilla, most commonly in the permanent first molar region of mandible. Clinically, it results in a hard swelling over the jaw, producing facial asymmetry. Meanwhile, radiograph shows a characteristic feature of irregular pulpal cavity, showing new periosteal proliferation located in successive layers to the condensed cortical bone on stimulated site. The treatment method for Garre's osteomyelitis are removal of the infection source, root canal treatment, antibiotic medication, and incision and drainage. This report presents a case of Garre's osteomyelitis under 15 years old. The patient was successfully treated by antibiotic medication accompanied with root canal treatment. Since the symptom of pediatric patients is less severe than adult, careful diagnosis with history taking and clinical examination is necessary. Furthermore long-term follow-up examination is needed to prevent recurrence even after the symptom disapears.

In pithed rats, rising in diastolic blood pressure by clonidine, when intravenously injected, is expressed as the postsynaptic action, and inhibitory action on electrical stimulation-induced tachycardia by clonidine is expressed as the presynaptic inhibitory action. In this study it was aimed to observe the inhibitory effect of imipramine caused by a single and chronic administration on both postsynaptic and presynaptic action of clonidine in pithed rats, and discussed in relation with the mechanism of antidepressant action of imipramine. 1) A rise of diastolic blood pressure by clonidine was not antagonized by prazosin, but by both phentolamine and piperoxan. 2) The inhibition by clonidine of tachycardia which was induced by electrical stimulation was also antagonized by phentolamine and piperoxan, but not by prazosin. 3) The increase in diastolic blood pressure in response to clonidine was inhibited by both a single or chronic administration with imipramine (20 mg/kg). It was more pronounced in the latter. 4) The inhibitory action of clonidine on the tachycardia was markedly inhibited by both types of administration with imipramine, between which there showed little difference. It is concluded that the presynaptic ${\alpha}_2-adrenoceptor$ is rather sensitively affected by a single administration with imipramine, and a long-term imipramine treatment may inhibit both pre- and postsynaptic ${\alpha}_2-adrenoceptors$, simultaneously. Furthermore, it was seemed unlikely that these results provide the evidence :to support the fact that the subsensitivity of presynaptic ${\alpha}_2-adrenoceptor$ may be the mechanism of action of tricyclic antidepressant.

Purpose : Recently, early surfactant replacement and tidal volume based gentle ventilation has been a fundamental treatment of respiratory distress syndrome(RDS). The aims of this study were to survey the changes in ventilator care duration and rate of complication in RDS groups. Methods : We performed a retrospective study of 255 newborn infants less than 1,500 g admitted to the neonatal intensive care unit(NICU) and discharged from January 1999 to December 2003. 141 of 255 newborn infants were RDS groups that required invasive management, such as endotracheal intubation, surfactant replacement and assisted ventilation. We analyzed epidemiologic data to study the changes in ventilator care duration and outcome of RDS groups. Results : Of 141 RDS groups, 135 were mild to moderate RDS groups and only 6 were severe RDS groups. 24(17.8%) of 135 mild to moderate RDS groups and 3(50%) of 6 severe RDS groups were antenatal no use of maternal dexamethasone. 127(90.1%) of 141 RDS groups underwent replacement of surfactant during 3 hours after birth. 121(85.9%) weaned within 48 hours. Conclusion : Our study shows a decreased frequency of severe RDS by a antenatal use of maternal dexamethasone and decreased duration of ventilator care by early surfactant replacement and gentle ventilation.

Purpose: The purpose of this study is to present the treatment results and to identify possible prognostic indicators in patients with locally advanced hypopharyngeal carcinoma. Materials and Methods: Between October 1985 to December 2000, 90 patients who had locally advanced stage IV hypopharyngeal carcinoma were studied retrospectively. Twelve patients were treated with radiotherapy alone, 65 patients were treated with a combination of chemotherapy and radiotherapy, and 13 patients were treated with surgery and postoperative radiotherapy with or without neoadjuvant chemotherapy. Total radiation dose ranged from 59.0 to 88.2 Gy (median 70 Gy) for radiotherpay alone. Most patients had ciplatin and 5-fluorouracil, and others had cisplatin and pepleomycin or vincristin. Median follow-up period was 15 months. Kaplan-Meier method was used for survival rate and Cox proportional hazard model for multivariate analysis of prognostic factors. Results: Overall 3-and 5-year survival rates were 27% and 17%, respectively. The 2-year locoregional control rates were 33% for radiotherapy alone, 32% for combined chemotherapy and radiotherapy, and 81 % for combined surgery and radiotherapy (p=0.006). The prognostic factors affecting overall survival were T stage, concurrent chemoradiation and treatment response. Overall 3-and 5-year laryngeal preservation rates in combined chemotherapy and radiotherapy were 26% and 22%, respectively. Of these, the 5-year laryngeal preservation rates were 52% for concurrent chemoradiation group (n=11), and 16% for neoadjuvant chemotherapy and radiotherapy (n=54, p=0.012). Conclusion: Surgery and postoperative radiotherapy showed better results than radiotherapy alone or with chemotherapy. Radiotherapy combined with concurrent chemotherapy is an effective modality to achieve organ preservation in locally advanced hypopharyngeal cancer. Further prospective randomized studies will be required.

This study was conducted to determine the effect of the adrenal function on the reproductive organs in immature rats treated with PMS. Two hundred and ten female rats (Wistar-Imamichi albino rats) of 21 days old (body weight : $58.7{\pm}3.53g$) were disposed in the intact rat group (Int.-) and adrenalectomized rat group (Adx.-) and then each group was devided into 3 subgroups, such as control (-Cont.), PMS treated (-PMS) was administered subcutaneously with 25 IU PMS, and and PMS cortisol treated groups (-PMS+Corti.) with 25 IU PMS and $30.0{\mu}g$ cortisol on 5 th day (aged 26 days old) after adrenalectomy, while the control groups with physiological salt solution by the same way. The reprodutive organs were observed at 48, 54, 60, 66, 72, 78 and 84 hours after hormone treatments. The results obtained were as follows ; 1. The measurments of time average ovary weight in all treated groups were increased with the elapse of time after treatment, and the difference among the treatments was significant (p<0.01) in the all observation time. But the difference of those was not recognized in Int.-Cont. and Adx.-Cont. groups. In the multiple range test. ovary weight of adrenalectomized rat groups (Adx.-PMS and Adx.-PMS+Corti. groups) was significantly (p<0.05) lighter than those of intact rat groups (Int.-PMS and Int.-PMS+Corti. groups), and the effect of cortisol administration was not reconized. 2. The difference of uterus weight was significantly reconized (p<0.01) in all observation time. The weight in Int.-PMS and Int.-PMS+Corti. groups was heavier until 66 hours after treatment, but the values in the adrenalectomized Adx.-PMS and Adx.-PMS+Corti. groups were heavier after 72 hours. The multiple range test showed that the significant difference was not found between Int.-PMS and Int.-PMS+Corti. groups, and Adx.-PMS and Adx.-PMS+Corti. groups. 3. The adrenal weight was not significantly different among the compared groups.

The present study was made in order to clarify the anti-emetic effect by needle-acupuncture (AP), injection-AP and moxibustion in xylazine - induced vomiting of dogs. Twelve mongrel dogs (4 months to 5 year old, 2 to 4 kg of body weight), eleven mongrel dogs (4 months to 5 years old, 2 to 10 kg of body weight) and twelve mongrel dogs (4 months to 1 year old, 2 to 4 kg of body weight) were used for clarification of anti-emetic effect by needle-AP, injection-AP and moxibustion, respectively. The experimental animals were devided into control(6 heads), BL-21(6 heads), CV-12(6 heads) and BL-21+CV-12(6 heads) groups using total 6 dogs with vomiting selected in preliminary experiment, respectively in needle-AP treatment. In addition, the experimental dogs were divided into control (11 heads), BL-21 (6 heads) and CV-12(6 heads) groups using 11 dogs, respectively in injection-AP treatment. In moxibustion treatment the experimental dogs were divided into control (6 heads), BL-21(6 heads) and CV-12(6 heads) groups using 6 dogs, respectively. Five days after the experiment of one group was finished, the other group was examined in each experiment. Acupuncture needle was maintained for 20 minutes in needle-AP treatment. Metoclopramide was used in injection-AP treatment. Commercial moxa was used in moxibustion treatment. Vomiting was induced by intramuscular injection with $2{\%}$ xylazine 20 minutes after treatments of needle-AP, injection-AP and moxibustion, respectively. The vomiting rates of BL-21($33.3{\%}$), CV-12($50{\%}$) and BL-21+CV-12($33.3{\%}$) were lower than that of control($66.7{\%}$) and vomiting times of experimental groups were similar to that of control in needle-AP treatment. The vomiting rates of BL-21 ($0{\%}$) and CV-12($16.4{\%}$) were lower than that of control($66.7{\%}$) and the vomiting time of CV-12 group was similar to that of control group in injection-AP treatment. The vomiting rates of BL-21($33.3{\%}$) and CV-12($33.3{\%}$) were lower than that of control ($66.7{\%}$) and vomiting times of experimental group were similar to that of control group in moxibustion treatment. In conclusion, it was considered that needle-AP, metoclopramide injection-AP and moxibustion at BL-21 and CV-12 were effective for anti-emesis in xylazine induced vomiting of dogs and metoclopramide injection-AP was the most effective method for anti-emesis among them.
