For lesions like intracranial aneurysms which are located near highly vascularized regions, adequate dissection becomes almost impossible unless local blood flow can be reduced. Deliberate hypotension, purposefully lowering the arterial pressure to a level at which bleeding is no longer a problem, facilitates surgery, allows performance of a better dissection, and shortens the length of the procedure. Currently, the most useful method for induced hypotensive anesthesia is the use of chemical drugs, such as trimethaphan, nitroprusside and halothane. Induced hypotension with halothane has been reported to be a relatively safe and useful method by Murtagh (1960) and Schettini, et al (1967). Halothane has the effect of depression of myocardial contractility, central autonomic inhibition, ganglionic blocking action and suppression of the peripheral actions of norepinephrine and direct vasodilation on the vessel wall. The advantage of halothane is the reduction of mean arterial pressure slowly (1-3 mm Hg/min) and it has a transient effect on EKG, little effect on brain cortical function and appropriate oxygen supply to brain tissue. The halothane induced hypotension in 100 cases of intracranial aneurysm surgery, which were performed at Severance Hospital of the Yonsei University College of Medicine from .1972 to 1977, was investigated clinically. The results of our study were as follows: 1) The locations of intracranial aneurysm in order were the anterior cerebral artery (37 cases), internal carotid artery (35 cases), middle cerebral artery (23 cases) and posterior cerebral artey (2 cases). Three cases of multiple cerebral aneurysm were found in our study. 2) In the hypotensive phase, the mean systolic and diastolic pressures were 73. 45 mmHg+/- 0. 86, 54. 95 mmHg+/- 0. 86 and the mean duration was 34. 74 min+/- l. 60. 3) The blood pressure control by halothane was comparatively easy and there was no cliaical evidence of direct injury to the brain, heart, kidney and liver due to halothane induced hypotension. 4) The mortality rate in the 100 cases of the intracranial aneurysm was 16 percent. From the above observation it may be concluded that the technique of deliberate hypotension induced by halothane anesthesia is a useful method in the surgery of intracranial aneurysm.

Tachycardia and hypertension are well documented complications of laryngoscopy and tracheal intubation in normal patients(Reid and Brace, 1940; Burstein et al, 1950; King et al 1951; Takeshima et al, 1964; Forbes and Dally, 1970). This phenomenon has been studied in detail in cats by Tomori and Widdicombe(1969), who found it to be associated with an increased impulse traffic in the cervical sympathetic efferent fibers. This nervous activity was especially increased by stimulation of the epipharyngeal and laryngopharyngeal regions, and was accompanied by the largest hypertensive response(Takki et al, 1972). Also various arrhythmias were elicited by vagal stimulation during endotracheal intubation(Burstein et al, 1950: King et al, 1951; Forbes et al, 1970), and it has been known that cardiac arrest could be observed in severe cases(Burstein et al, 1950; Dwyer, 1953; Raffan, 1954; Lander and Mayer, 1965). That hypertension during induction of anesthesia in critically ill patients may be harmful is substantiated by reports of cerebral hemorrhage, left ventricular failure and life threatening cardiac arrhythmia(Forbes and Dally, 1970; Dingle, 1966; Masson, 1964; Katz and Bigger, 1970). Pharmacologic attempts to attenuate these blood pressure and heart rate elevations and appearances of arrhythmia have been tried but theese approaches have been only partially successful. We selected at random 60 adult patients who had received operation under the general anesthesia with intubation at Severance Hospital from August to September, 1979. They were divided into 4 groups. Group l was normotensive without trimethaphan(n=20), Group ll was normotensive with trimethaphan(n=20), Group ll was hypertensive without trimethaphsn(n=10) and Group lV was hypertensive with trimethaphan(n=10). The changes of arterial blood pressure and pulse rate, and appearance of arrnythmia were analyzed and data were compared between groups. The results were as follows; 1. In the trimethaphan injected group, during induction attenuation of increase in blood pressure was not significant in the normotensive group but was statistically significant in the hypertensive group. 2, The effects of trimethaphan on changes of pulse rate were not significant during laryngoscopic insertion under general anesthesia. 3, On EKG of hypertensive patients the trimethaphan injected group revealed fewer abnormal EKG findings than the control group. It is suggested from the above results that intravenous injection of a small amount(0.1 mg/kg) of trimethaphan in a hypertensive patient just before endotracheal intubation can be used as one method to prevent a dangerous hypertensive crisis.

BACKGROUNDS: Culture of Helicobacter pylori (H. pylori) from gastric biopsy specimens is a standard method with high specificity among H. pylori diagnostic tools and is also essential for antibiotic susceptibility test. The authors compared 5 selective media for H. pylori culture and tested fresh human serum instead of fresh animal blood as a media composite. METHODS: Gastric biopsy specimens from endoscopic examination were obtained from 50 patients (gastric ulcer:33, duodenal ulcer:12, stomach cancer:5) and they were finely minced with a tissue grinder. Specimens were inoculated onto 5 media (1. Columbia agar with 5% sheep blood, 2. Columbia agar with 10% human serum, 3. Thayer-Martin agar with 5% sheep blood, 4. T-M agar with 10% human serum, 5. T-M agar with 10% hemoglobin) and cultured for 3~7 days under microaerophilic condition. Gram stain, oxidase, catalase, and urease tests, were undertaken on typical colonies for diagnosis of H. pylori. Contamination by other organisms, number and size of H. pylori colonies were compared for each media. RESULTS: Positive culture rate of H. pylori was not significantly different among 4 media except TM agar with 10% hemoglobin. However T-M agar with 10% fresh human serum was considered as the best composition for culture of H. pylori because it had the least contaminating organisms and produced the largest colony sizes. CONCLUSIONS: These findings suggest that T-M agar with 10% fresh human serum can replace columbia agar with 5% sheep blood which has been commonly used for culture of H. pylori from gastric biopsy specimens. Fresh human serum, which is easily obtained in the clinical laboratory, can replace animal bloods in making media for H. pylori.

Silicone gel breast implants may induce local(fibrous capsular contracture) or systemic(rheumatoid arthritis, systemic sclerosis, etc) complications. The exact mechanism of fibrous capsular contracture has not been fully understood. In the present study, we tried to find out the effect of silicone gel on the fibroblast proliferation which has been known as a major contributing factor in fibrous capsular contracture formation. In vitro, activated macrophages are known to secrete monokines which affect fibroblast proliferation and collagen synthesis. And tumour necrosis factor-alpha(TNF-alpha) and interleukin-6(IL-6), which were released by macrophages, were reported as potent stimulator of fibroblast proliferation. The goal of this study is to investigate the role of macrophages and tumour necrosis factor-alphaor interleukin-6 in the interaction of fibroblasts and silicone gel. We designed four groups, two experimental and two control, using Institute for Cancer Research(ICR) mouse peritioneal macrophage and silicone gel. For the preparation of the conditioned medium of macrophages, peritoneal macrophages were prepared and cultured for 24 hours on the silicone gel-coated and naked (not coated) surface [silicone gel-macrophage conditioned medium(SCM; experimental group) and normal polystyrene-macrophage conditioned medium(NCM; control group) respectively]. To correct the effect of 10% fetal bovine serum which was included in Rapid Prototyping and Manufacturing Institute (RPMI) 1640 medium and draw the effect only by macrophages, the RPMI 1640 medium with 10% fetal bovine serum was cultured by the same method on the silicone gel-coated and naked surface (silicone gel-macrophage free conditioned medium; SFM and normal polystyrene-macrophage free conditioned medium; NFM respectively). Each conditioned medium was added onto NIH 3T3 fibroblasts culture at a final 25% concentration of total culture medium and followed by the cultivation for 24 hours. For antibody neutralizing experiments, each conditioned medium was preincubated with polyclonal rabbit anti-mouse TNF-alpha antibody or polyclonal rat anti-mouse IL-6 antibody for 1 hour and then, conditioned medium with antibody was added to the culture medium of NIH 3T3 fibroblasts by the same method. After 24 hours cultivation, total number of viable fibroblast(cell growth), DNA synthesis and collagen synthesis of fibroblasts with each medium were measured by sulforhodamine B(SRB) assay, 3H-thymidine and 3H-proline incorporation respectively. The results were as follows: 1. In the experiment about the effect of the conditioned medium on the fibroblast activity, the experimental group(SCM), compared with the control group(NCM), showed a significant increase of the cell growth (p<0.01), a significant decrease of DNA synthesis(p<0.001), but no significant difference in the collagen synthesis. 2. In the experiment about the effect of polyclonal rabbit anti-mouse TNF-alpha antibody on the fibroblast activity, after the addition of antibody the experimental group, compared with the control group, showed a significant decrease of the cell growth(p<0.001), a significant increase of DNA synthesis(p<0.01), but no significant difference in the collagen syn thesis. 3. In the experiment about the effect of polyclonal rat anti-mouse IL-6 antibody on the fibroblast activity, after the addition of antibody the experimental group, compared with the control group, showed a significant decrease of the cell growth(p<0.001), a significant increase of DNA synthesis(p<0.0001), but no significant difference in the collagen synthesis. In conclusion, culture supernatants (conditioned medium) of peritoneal macrophages, activated by silicone gel, stimulate the NIH 3T3 fibroblast proliferation. TNF-alpha and IL-6, products of macrophage, are involved in the stimulation of NIH 3T3 fibroblast proliferation in an in vitro condition.

We report here on a new technique using polymethylmethacrylate to manage vertebral osteoporotic compression fractures in three patients. These patients presented with acute back pain that manifested itself after minor trauma. Osteoporotic compression fractures were diagnosed via plain X-ray and magnetic resonance imaging studies. The patients were treated with absolute bed rest and non-steroidal anti-inflammatory drugs. Despite of the conservative treatment, the patients experienced severe, recalcitrant and progressive pain. The vertebrae were collapsed over 50% or kyphotic deformity was seen on the radiologic materials. We performed a new technique called lordoplasty, which is derived from percutaneous vertebroplasty. The patients experienced a reduction in pain after the procedure. The wedge and kyphotic angles of the fractured vertebrae were significantly restored.

Tracheal stenosis is now a well-recognized, and very serious complication following increased use endotracheal tubes of tracheostomies with air inflated cuffed tubes and assisted ventilation. Up to 10% of patients surviving treatment have been reported to develop stenosis following closure of tracheostomy and some prospective studies predict a 16~20% incidence of stricture following prolonged cuffed tube ventilation. The most important principle is prevention. Once stenosis is established, the logical approach is resection of the stenotic segment and reestablishment of an adequate airway by primary anastomosis or the insertion of a tracheal substitute. In this regard, Pearsor, Grillo, Naef and Binet have made major contributions to the technique of reconstruction of the tracheo-bornchial tree after extensive resection. Strictures are described both in the region of the stoma and at the level of the inflatable cuff. Anesthetic management of these patients should focus on maintenance of the airway and adequate ventilation. If not, hypoxia or cardiac arrest can occur during a prolonged operation due to alvsolar hypoventilation. Extracorporeal circulation for tracheal stenosis reconstruction was first used by Woods for prevention of hypercarbia and hypoxia. The Department of Anesthesiology of Yonsei University has had experience in the anesthetic management of two cases of tracheal stenosis reconstruction using extracorporeal circulation during surgery, these cases are reported along hear with references from the literature.

BACKGROUND: To validate Omron HEM 907 XL blood pressure monitor (test device) against auscultatory mercury sphygmomanometer in children aged 7-8 years old in accordance with International Protocol of European Society of Hypertension revised in 2010 (ESH-IP2) and British Hypertension Society (BHS) protocol. METHODS: Seventy-five children and adolescents were recruited for the study. A validation procedure was performed following the protocol which was prepared on the basis of ESH-IP2 and BHS protocol for children and adolescents. Each underwent 7 sequential BP measurements alternatively with a mercury sphygmomanometer and the test device. The results were analyzed according to the validation criteria of ESH-IP2. RESULTS: The mean (blood pressure [BP], +/- standard deviation [SD]) difference of absolute value between the test device and mercury sphygmomanometer readings in all the 75 subjects was 3.26 +/- 3.08 mm Hg for systolic BP and 4.11 +/- 3.50 mm Hg for diastolic BP. These results fulfilled AAMI criterion of mean +/- SD below 5 +/- 8 mm Hg for both systolic and diastolic BP. The proportion of test device-observer mercury sphygmomanometer BP differences within 5, 10 and 15 mm Hg were 81%, 96%, 99% for SBP and 72%, 93%, 99% for diastolic blood pressure (DBP), respectively, in the part 1 analysis, so both systolic blood pressure (SBP) and DBP passed the part 1 criteria. As for the part 2 analysis, SBP passed the criteria, bur DBP failed. CONCLUSIONS: Omron HEM 907 XL BP monitor failed an adapted ESH-IP2, though SBP passed. When comparing the BP readings by oscillometers with mercury sphygmomanometer, the differences between them, particularly in diastolic BP, should be taken into account, because DBP can be underestimated.
