Histamine이 개의 자궁 평활근 운동성에 미치는 영향
鄭憲植,金鍾涉,金周憲 慶尙大學校 1985 論文集 Vol.24 No.1
The responses of motility to histamine were investigated with canine uterine longitudinal muscle. The results were summarized as follows: 1. Histamine has been shown to induce contractility with dose-dependent between 10_-7 M and 10_-5 M in canine uterine longitudinal muscle. 2. The contraction induced by histamine was completely blocked by Hi-receptor blocker, chlorpheniramine, at a concentration of 10_-6 M; but was not blocked by H_2-receptor blocker, cimetidine, at a concentration of 5×10_-7 M. 3. The contraction induced by histamine was not blocked by the cholinergic receptor blocker, atropine, at a concentration of 10_-6M. 4. The contraction induced by histamine did not affect adrenergic o-receptor blocker, phenoxybenzamine(10_-6M), and adrenergic β-receptor blocker, propranolol(10_-6M). From these results, it was concluded in dog that the contractility of uterine smooth muscle by histamine was only through H_1-receptor, and that it may not be related to the cholinergic and adrenergic receptor.

Author divided 60 patients who got lower abdomen or lower extremity surgical operation into three groups. Each group consisted of 20 patients. We injected ketamine 10㎎, 20㎎, and 30㎎ respectively into the epidural space when the patient complained of pain postoperatively and observed the postoperative analgesic effect of ketamine. Finally, we concluded the following : 1) The onset time of analgesic effect. : The analgesic effect appeared within 10 minutes in 3 groups and the significant difference among them was not seen. 2) The duration of analgesic effect : The duration of analgesia was relatively short with less than 1 hour on an average in all 3 groups and was not constant. 3) Cardiopulmonary system. : The significant change of blood pressure, pulse and respiratory rate was not seen in all three groups and and the difference among them also was not seen. 4) Side effects. : Sedative action(16%), nausea(10%), dizziness(5%), headache(3.3%) From above results, the epidural administration of ketamine is not suitable for postoperative pain management because of a lot of side effects as well as short and inconstant duration of analgesic effeet.

This study was designed to clarify histological changes in the experimental rabbit ureter after unilateral prartial or complete ureteral obstruction. A total of 20 adult white rabbits were divided into 4 subgroups in the partial obstruction followed by 2 weeks, partial obstruction followed by 4 weeks, complete obstruction followed by 2 weeks, complete obstruction followed by 4 weeks. The normal control group consisted of 5 adult white rabbits. The H & E stain. light microscopy were used. Abnormal histological fingings were showed in ipsilateral ureter of all subgroups; dilatation of ureter, epithelial cell atrophy or loss, interstitial fibrosis, interstitial inflammation. These findings were most severe in the complete-obstructed ureter for 4 weeks. There were no significant changes in contralateral ureter of all subgroups. Despite of progressive histological changes in ipsilateral ureter no abnormal findings were showed in contralateral ureter. We suggest that long term experimental investigation for histological changes in ipsilateral ureter and compensatory changes in contralateral ureter should be done.
하악골 절제술후 재이식된 돌결자가골 재이식 : 치험 3례

We described three cases of immediate reimplantation of a frozen-thawed autogenous mandible composed of a mixture of iliac bone, marrow, and particulate hydroxyapatite in tumors of the mandible. Acceptable outcomes were obtained in three patients who underwent immediate autogenous mandibular graft reconstruction. The conditions leading to successful outcome of the procedure are also discussed. Reimplantation of frozen autogenous lesioned mandible was performed in three patients with mandibular tumors. Two reimplanted grafts survived without complications following surgery. One case had postoperative infection that resolved with appropriate antibiotic treatment. There were no recurrences of the primary lesions. Satisfactory facial contour after surgery was achieved. These results are most promising, and we believe that, with further refinement, this technique will offer a new and acceptable modality for facial reconstruction in patients with cancer.
척수강내 Bupivavacain에 첨가한 소량의 Neostigmin의 진통효과와 부작용
소금영,정종달,김병철,유벙식,안태훈,김훈정,임경준 조선대학교 2000 The Medical Journal of Chosun University Vol.25 No.2
Background : Spinal cholinergic receptor has been shown to have a antinociceptive action, an effect that can be mimicked by spinal cholinesterase inhibitor. Intrathecal injection of neostigmine cause analgesia and adverse effect in a dose-dependent pattern in the patients. The purpose of this study was to determine whether small doses of intrathecal neostigmine (10, 25 and 50 ㎍) produce analgesia and any side effects. Method : After getting informed consents, 60 patients scheduled for orthopedic surgery of lower extremities under spinal anesthesia were randomly assigned to one of four groups. Using dose-ranging design, patients received either normal saline or neostigmine l0, 25 or 50 ㎍ in a 1-㎎ solution of 5% glucose in normal saline with heavy bupivacaine 12 ㎎. Heart rate, blood pressure, degree of motor and sensory block were recorded. The assessment of postoperative analgesia included time to first rescue, total number of rescue medication and pain score on visual analog scale (VAS) at 1, 3, 6, 9, 12, 24 hour. Nausea and vomiting were assessed by using the visual analog scale at 24 hr postperatively and the incidence of them was recorded postoperatively. Result : There were no significant differences among the four groups in characteristics of spinal blocks. Compared to saline, neostigmine groups significantly prolonged time to first rescue medication and decreased total number of rescue medication and pain visual analog scale score, but incidence of nausea and 24hr nausea VAS score were not increased in neostigmine group compared to control group. Conclusion : These data in patients injected intrathecal neostigmine suggest that analgesia may occur at doses less than neostigmine 50 ㎍ and neostigmine 50㎍ has a better analgesia effect with fewer side effects than other doses for postoperative analgesia.
교정 치료 환자에 있어 항균 varnish 처치 전후의 타액 내 Streptococcus mutans 균주의 변화에 관한 연구

Dental caries is one of the most prevalent dental diseases in Korea and its prevention is very important in orthodontic therapy. For the cleansing action of saliva itself and/or tooth-brushing is lowered in patient with fixed orthodontic appliance, oral hygiene of the patient becomes worse, which provides more favorable environment for micro-organisms. Chlorexidine, one of the series of bisguanide, has been reported to be strong antimicrobial agent and very effective on Streptococcus mutans. The purpose of this study is to evaluate the possibility of chlorhexidine as a anticariogenic agent in fixed orthodontic therapy. We used the varnish containing chlorhexidine as a main ingredient for the chemical control of salivary S.mutans in patients with fixed appliance therapy. We applied the varnish containing chlorhexidine on the labial and interproximal surface of the teeth before bonding and banding teeth of our patients(N=20) and compared to control group patients(N=20). Before the application of chlorhexidine varnish and four times periodically after the completion of fixed appliance set-up, we sampled saliva of both group patients and incuvate S.mutans for 24 hours. In the culture study of sampled saliva, counting the number of S.mutans colonies, we founded as follows : 1. In patients with fixed appliance therapy, the risk of dental caries increase when it compared to that of preorthodontic treatment ; The number of salivary S.mutans increase in patient's oral cavity. 2. The experimental agent that contain chlorhexidine is effective to reduce the number of salivary S.mutans. 3. For the effect of this agent is not ever-lasting, periodical application is needed, and additional study for economical interval and number of application is needed.
