The investigation of systolic time intervals and hemodynamics was performed in 42 patients with liver cirrhosis by noninvascive methods. The patients were divided into four groups according to the presence or absence of anemia and/or ascites: i.e. group I; cirrhosis without anemia and ascites, group II; cirrhosis with ascites only, group III; cirrhosis with anemia only, and group IV; cirrhosis with ascites and anemia. In the resting state of the patients, the systolic time intervals and hemodynamic data were measured by the high speed simultaneous recordings of electrocardiogram, phonocardiogram, carotid and femoral arterial pulse tracings, and compared with those obtained from 155 normal adult subjects. 1. The pulse were increased considerably in group IV, and diastolic blood pressure was elevated in group II with significance. 2. The stroke volume and cardiac output were increased significantly in group III. 3. The peripheral resistance was reduced particularly in group III, and the volume elasticit coefficient was decreased in group IV. 4. The QS1 interval was prolonged significantly in group II and IV, but QS1 interval corrected by multiple regression equation proposed by our laboratory (illustrated in the text) did not show significant difference compared with that of normal subjects. 5. The left ventricular ejection time(LVET) and total electromechanical systole(QS 2) appeared to be shortened in group II and IV, but the corrected LVET and QS 2 were not different significantly from those of the normal subjects

3.Effects of Preoxygenation during induction of General Anesthesia.
Korean Journal of Anesthesiology 1985;18(1):92-97
After the description of the necessity of denitrogenation in rebreathing anesthesia circuits some decades ago, many methods were recommended for techniques of ventilation with oxygen before induction of anesthesia for the purpose of maintaining arterial oxygenation during laryngoscopy and tracheal intubation . In this point of view, we compared PaO2, MAP, PaCO2, pH of non-preoxgenation group(oxygen was given after succinylcholine was injected) with those of preoxygenation group(owygen was given after thiopental sodium was injected). The cases were selected randomly who blongs to ASA class l or ll(without cardiopulmonary abnormalities) and ages betweens 27 years and 66 years old. Before induction of general anesthesia, we cannulated radial artery after Allen's test and sampled arterial blood before anesthesia, after thiopenthal and succinylcholine were injected respectively, when tracheal intubation was done in the two groups and measured PaO2, PaCO2, MAP, pH respectively. PaCO2, MAP, pH changes in the two groups were not significant and of no clinical significanses. PaO2 after tracheal intubation showed marked increase in preoxygenation group compared to non-preoxygenation group but mean PaO2 was maintained within normal range in non-preoxygenation group with the apnetic period of tracheal intubation. WE found that non-preoxygenated patients also had normal range of PaO2 during the whole process of induction of anesthesis. But I think preoxygenation technique of any method can reserve more time and will do more effectively, especially when times consuming events of difficult intubation of any reason occurs.

OBJECTIVES: MDM-2 is an oncoprotein that inhibits p53 tumor suppressor protein. Amplication and over- expression of its protein have been observed in human malignancies, and these abnormalities have a role in tumorigenesis through inactivation of p53 function. To elucidate the role of p53 and MDM-2 protein in cervical neoplasia we investigated the expression rates of MDM-2 and p53 protein in surgically resected specimens. METHEDS: Immunohistochemical studies using anti-p53 and anti-MDM-2 protein in the paraffin embedded section of 62 cases including cervical intraepithelial neoplasm(CIN) and invasive cervical cancer were performed. RESULTS: Expression rates of p53 protein were 25% in CIN I& CINII, 20% in CINIII, and 44% in invasive carcinoma, respectively. The MDM-2 protein were 33% in CIN I & CIN II, 16% in CIN III, and 48% in invasive carcinoma, respectively. There was no evident correlation between p53 positivity and MDM-2 positivity(p>0.05). However, correlation between MDM-2 negativity and p53 negativity was statistically significant(p=0.002) CONCLUSION: These data suggest that the expression of p53 protein is presumed to be necessarily correlated with MDM-2 protein expression in cervical neoplasia.

PURPOSE: We evaluated changes in bone mineral density and biochemical bone turn over markers resulting from intravenous administration of zoledronic acid for the purpose of increasing bone mineral density and decreasing bone turnover rate in patients who had received operative treatment after hip fracture. MATERIALS AND METHODS: We carried out a retrospective study of 34 patients who had received injections of zoledronic acid after surgical treatment for hip fracture from January 2009 to June 2010, with a follow up period of more than one year. We evaluated pre and post T-scores of DXA in spine, proximal femur and femoral neck along with biochemical bone metabolic markers, and we then analyzed each factor. RESULTS: T score was enhanced in all cases with pre T-score -4.2 and post T-score -3.3 revealing statistical significance (P<0.05). In addition, two biochemical bone turnover markers were observed to decrease in most patients. Three days after drug administration, 7 patients(20.6%) had minor adverse effects. There were no serious complications such as atrial fibrillation. CONCLUSION: No major adverse effects were observed, only minor ones in patients who had been injected with zoledronic acid for the prevention of osteoporotic fracture after surgical treatment for hip fracture. We confirmed the affirmative effects on changes in bone mineral density and biochemical bone turn over markers associated with the use of this drug.

It is well known that the murine T helper cell clones are divided by their lymphokine secretory activities. One is the Th-1 cell, producing IL-2 and IFN after stimulation and the other is the Th-2 cell, producing the IL-4 and IL-5. This study was undertaken to evaluate the immunomodulatory properties of the bacterial lipopolysaccharide(LPS) on the lymphokine production in vivo and in vitro. The results were as follows: There were no effects on the lymphokine secretion by the in vitro treatment of the LPS. The in vivo treatment of the LPS decreases the capability of the production of IL-2 and IFN , whereas it increases the capability of IL-4 production. The altered capacity of the lymphokine production was recovered about 2 weeks after the treatment of the LPS. There were no differences on the lymphokine production between E-coli LPS and salmonella LPS. The capacity of the lymphokine production was the same in the treatment of a non-heated LPS or heated-LPS. The lymphokine production of the mice which were desensitized by the long term treatment of the LPS was not different from the control mice. The in vitro treatment of RU486 can block the alterations of the lymphokine production after the treatment of the LPS. In summary, one can tell that the LPS increases the secretion of the IL-4 through the endogenous secretion of the glucocorticoids.

BACKGROUND AND AIMS: This research was conducted in order to study the clinical usefulness and stability of the propofol used for sedation during upper gastrointestinal endoscopy. METHODS: The objective of this research was to study one hundred patients, who were chosen based upon their preference to be examined through diagnostic upper gastrointestinal endoscopy accompanied with propofol from July 1998 to August 1998, and who showed normality in the pulmonary function test and ECG. The elements observed were hemodynamic variations, injection dosage, injection time, recovery time and side effects. RESULTS: All patatints had no recollection of the procedure during gastrointestinal endoscopy. It was found that the older the patients were, the less amount of propofol sleep was indued. Systolic blood pressure, diastolic blood pressure and the mean arterial blood pressure were lowered noticeably after sleep, compared with those before the injection of propofol, while the heart rate hardly changed. CONCLUSIONS: Profopol is believed to be a useful sedative for upper gastrointestinal endoscopy. As blood pressre can be lowered however, a cautious attitude should be considered when injecting propofol in the elderly or in patients who have cardiovascular disease.

Journal of Korean Foot and Ankle Society 2015;19(4):161-164
PURPOSE: The purpose of this study is to define the geographic patterns of partial avascular necrosis (AVN) of the talar body and to determine whether there were any predictors of both the location and occurrence of partial AVN. MATERIALS AND METHODS: Nineteen patients with fracture of the talar neck treated by open reduction and internal fixation and followed up for more than 1 year were analyzed. The radiographs were examined 6 to 8 weeks after the operation for Hawkins sign and if it was not observed, magnetic resonance scans were performed. The three-dimensional analysis was performed using Mimics 17.0 (Materialise). The incidence of collapse and time to operative intervention was recorded. RESULTS: Partial AVN of the talar body was observed in six out of 19 patients. The avascular segment of the talar body was located predominantly in the anterolateral portion. The average volume of the avascular segment was 289 mm3, and it occupied 1% of total volume of the talus, and 10% of the talar dome. Collapse occurred in one patient in the area of the avascular process. There were no observable trends with regard to Hawkins classification, incidence of collapse, or time to operative intervention to the location of the avascular segment. CONCLUSION: Partial AVN can occur after fracture of the talar neck. The predominant location of the avascular segment was the anterolateral portion of the talar body. This information may be helpful to understanding the process of avascular necrosis of the talar body.
