Fractures of the tibial condyles, involving as they do weight-bearing articular surfaces and important soft tissues such as collateral ligaments, cruciate ligaments and semilunar cartilages present a variety of problems in treatment and prognosis. Apley, Slee, and others maintained the opinion that most fractures of the tibial condyles could be managed conservatively. On the other hand, Rombold, Schatzker, and others seemed to consider closed treatment to be virtually a form of therapeutic nihilism and adviced open reduction. But recently most authors agree that the method of treatment has to be selected in each individual case, and recommend anatomical reduction of the fracture as possible and early knee motion. During 7 years period from January 1974 to July 1981, of the tibial condylar fractures treated at the department of orthopaedic surgery, Han Gang Shim Hospital, 41 cases that could be followed have been analysed according to the cause, classification, method of treatment and result. The following results were obtained from the analysis of 41 tibial condylar fractures. l. Of the 41 cases, 34 (83%) were male and 7 (17%) were female. 2. Of the 41 cases, 32 (78%) were due to traffic accident, 25 pedestrian, 7 occupant, 8 (20%) were due to fall from height. 3. Of the 41 cases, 31 (76%) were associated with other injuries. 4. Of the 41 cases, 30 were treated by conservative method with functionally acceptable result in 22 cases (73%) and 11 were treated by open reduction with functionally acceptable result in 9 cases (82%). 5. According to the Hohl and Luck's criteria, acceptable functional result was obtained in 31 (76%) cases.

Changes in the number, the immunoreactivities and the ultrastructures of sero- tonin immunoreactive mucosal mast cells[MMCs] in rat gastrointestinal tracts after vagus nerve stimulation were investigated by using light and electron microscopic immunocytochemical methods. The vagus nerves were electrically stimulated with a square wave pulse generator for a duration of 5 minutes each, a total of 8 times at 2 minute intervals. Serotonin immunoreactive cells of the connective tissues of the gastrointestinal tract were mainly located in the lamina propria, and a small number of the cells were also scattered in the submucosa. By using electron microscopic immunocytochemistry and Wright stain, the serotonin immunoreactive cells of the lamina propria and the submucosa were identified to be MMCs. A few large-sized serotonin immunoreactive connective tissue mast cells [CTMCs], showing strong metachromasia with the Wright stain, were located together with the MMCs in the submucosa of the stomach. In most of the gut regions of the control group, the majority of the MMCs did not show any serotonin immunoreactivities and only a few MMCs showed weak serotonin immunoreactivities. After stimulation of the vagus nerves, the number and the immnu- noreactivities of the serotonin immunoreactive MMCs dramatically increased in all gut regions observed, especially in the small intestines. In the samples treated with the electron microscopic immnunocytochemical methods, hardly any serotonin immunoreactivities were detected in the MMCs of the control group. However, the serotonin imrnunoreactivities of the MMCs were significantly increased after vagus nerve stimulation. The serotonin immnunoreactive products were localized, following vagal stimulation, both in the peripheral matrix of the granules and in the cytoplasm. Also, it was confirmed ultrastructurally that the Golgi complexes were expanded in the MMCs of the vagal stimulation group. The above results suggest that vagus nerve stimulation may activate serotonin biosynthesis in MMCs.

This study was undertaken to investigate the ultrastructure of the neurons, neuroglial cells and capillaries in the area postrema[AP] of the Oriental discolured bat, Vespertilio superans. The AP of the bat was a single midline structure at the most caudal portion of the fourth ventricle. Most neurons in the AP were small cells, but their ultrastructure were similar to the typical neurons located elsewhere in the central nervous system. Astroglial cells and oligodendrocytes were also observed and showed their typical ultrastructure. Ultrastructural features of neurons, astroglial cells and oligodendrocytes were not changed during hibernating cycles. However, microglial cells were only found in the hibernating AP ; these cells were located in the parenchyma and near the blood vessels of the AP. Since the microglial cytoplasm was filled with phagocytotic inclusions, the nuclei of the these cells were eccentrically located. Phagocytotic cytoplasmic inclusions were shown to be composed of a dense irregular peripheral region and the pale round central region. A Large vacant space was often found in the electron lucent central region. Continuous and fenestrated capillaries surrounded by pericytes were found in the bat`s AP. Especially, Phagocytotic inclusions were found in the pericyte cytoplasm of the hibernating AP, and this result supports suggestion that pericytes might be phagocytotic cells. On the basis of the distributions of phagocytotic tells[pericytes and microglial cell], ultrastructure of these cells, morphology of their cytoplasmic inclusions, and the appearance of phagocytotic activity of the pericytes during the hibernating stage when microglial cells were observed, it can be concluded that pericytes may also participates in the formation of rrlicroglial cells. Tanycytes were also found in the bat AP.

An evaluation of axillary block in 803 clinical cases, during the period from January 1974 to June 1979, was made. Satisfactory results were obtained in 756 out of 803 blocks (94. 2%) with the axillary perivascular technique. The authors feetl that the axillary perivascular technique in which a relatively large volume(40~50ml) of anesthetic solution was administered into the perivasculsr space of the axilla was simple, convenient and had no serious complications compared to the supra-or subclavian perivascular technique and interscalene block for a diagnosis and treatment of upper extremities.

BACKGROUND: Recently, a lower incidence of late potentials has been reported in patients with acute myocardial infarction after successful thrombolysis when compared with conventionally treated patients. In another recent study, however, no significant effect of thrombolytic therapy on any abnormal signal average electrocardiography was found at 13 days after acute myocardial infarction. The present study was designed to determine the prognostic significance of the signal average electrocardiography and to evaluate the possible value of this technique as a noninvasive tool for monitoring of coronary occlusion and reperfusion. METHODS: Signal averaging was performed by using a signal average electrocardiography with bidirectional filterings before coronary artery occlusion, at 5 minutes after coronary occlusion and on reperfusion in 20 cats. Three of them died due to malignant ventricular arrhythmia during reperfusion. In all cats, approximately 250 beats were averaged. All data were analysed at filter frequency 25 to 250Hz, 40 to 250Hz and 80 to 250Hz. The following quantitative high resolutional electrocardiographic variables were calculated by computer : 1) filtered total QRS duration, 2) duration of HFLA(high frequency low amplitude) signals under 40uV, 3) RMS voltage of terminal 40ms, 4) mean Voltage of terminal 40ms, 5) average noise voltage. RESULTS: At the filter frequency of 40 to 250Hz and 80 to 250Hz, the filtered QRS duration and duration of HFLA signals 40uV were significantly prolonged at 5 minutes after coronary artery occlusion than before coronary occlusion(p<0.01). At the filter frequency of 40 to 250Hz and 80 to 250Hz, the RMS voltage(terminal 40ms) and mean voltage(terminal 40ms) were significantly prolonged at 5 minutes after coronary artery occlusion than before coronary occlusion(p<0.01, p<0.01 respectively). At the filter frequency of 80 to 250Hz, the filtered QRS duration and at the filter frequency of 25-250Hz, the duration of HFLA signals at 40uV were significantly shortened during reperfusion than at 5 minutes after coronary artery occlusion(p<0.01, p<0.05 respectively). At the filter frequency of 40 to 250Hz and 80 to 250Hz, the RMS voltage(terminal 40ms) and mean Voltage(terminal 40ms) were significantly shortened during reperfusion than at 5 minutes after coronary artery occlusion(p<0.01, p<0.01 respectively). There was no significant change of the filtered QRS duration, duration of HFLA signals 40uV,RMS voltage(terminal 40ms) and mean Voltage(terminal 40ms) after reperfusion compared with those of control at the filter frequency of 25 to 250Hz, 40 to 250Hz and 80 to 250Hz respectively. CONCLUSION: These results suggest that the signal average electrocardiography could be a valuable tool for monitoring the state of coronary artery occlusion and reperfusion.

BACKGROUND: Quyyumi et al described circadian variation of ischemic eletrocardio-graphic changes and heart rate in patients with and without significant coronary disease in 1985. Rocco et al also described circadian variation of transient myocaldial ischemia in patients with coronary artery disease. They also noted an increse in ischemic eletrocardiographic abnormalities in the morning hours.In recent years the important of circadian variation of cardiovascular phenomena has generated a great deal of interest. Such phonomena include the occurrence of ischemia in patients with both chronic stable angina and variant angina, myocaldial infarction, sudden cardiac death, ventricular arrhythmia and platelet aggregability. METHOD: To examine whether a significant circadain variation of transient myocardial ischemia exists and to better understand the character of such variation, 35 patients with againa pectoris(15 patients treated with nitrate and/or caclcum channel blocker and 20 patients without treatment) underwent 24 hours ambulatory monitoring of ischemic ST segment changes during daily life. RESULT: Only 21% of the episodes of ST depression were accompanied by chest pain. While 79% were asymptomatic. A significant circadian increase in ischemic activity was found with 44% of episodes and 40% of total ischemic time in not treated group, and 52% of episodes and 56% of total ischemic time in treated group, occuring between 6 A.M. to 12 P.M.(P<0.05 respectively) When the distribution of ischemic episodes was corrected for the variable time of waking, the peak ischemic activity was occuring in the 1st and 2nd hours after rising. There were no significant differences in heart rate at onset and heart rate at 1 min before onset. CONCLUSION: Is summary, transient myocardial ischemia in the absence of pain was more common and there were a significant circadian variation of transient myocardial ischemia with peak activity in the morning. In addition most of transient myocardial were not preceded by a rise in heart rate.

Sheehans syndrome is a known complication of pregnancy, It was described as a syndrome of hypopituitarysm due to acute ischemic necrosis of the anterior pituitary gland secondary to severe postpartum bleeding and shock. The neurophysis is usually preserved. But it can be involved in severe cases manifesting as diabetes insipidus. Because of its rare coexistence with Sheehans syndrome, diabetes insipidus is seldom recognized as a potential postpartum complication. The report describes a patient who developed Sheehans syndrome and diabetes insipidus immediately following delivery. Diabetes insipidus resolved spontaneously after 15 months, while panhypopituitarysm is persistent.

PURPOSE: To present the results of mdivastus and paramedian approach for total knee replacement arthroplasty (TKA). MATERIALS AND METHODS: Thirty two patients having bilateral total knee replacement arthroplasty were randomized prospectively-one knee having a vastus muscle-splitting approach(MVS) and the other knee having a median parapatellar approach(MPP)- to compare the difference in lateral release, operation time, postoperative ROM and drain amount, HSS score, return to SLR and extension lag at 2 weeks in TKA. RESULTS: The MVS approach offered an early advantages compared with MPP approach, especially in terms of lateral release[22(68.7%)on MPP and 5 15.6%) on MVS (p=0.014)], ROM at postoperative 2 week (p=0.043) and early return to SLR (p=0.023). There were no significant differences in operation time, postoperative ROM and drain amount, HSS score and extension lag. CONCLUSION: The MVS approach has the potential to improves the rapid restoration of quadriceps mus-cle control and to lead to reduction in the need for lateral release in TKA.

We describe a group of 3 cases of invasive meningococcal disease that occurred in a military training camp in April 2011. All three patients were hospitalized. Ultimately, two patients recovered and one died. One patient had meningitis, one patient had septicemia and meningitis, and the other had no definite septicemia or meningitis. Neisseria meningitidis serogroup W-135 was detected in the serum and cerebrospinal fluid (CSF) of all patients by real-time polymerase chain reaction. In the one case of mortality, two strains were isolated from the patient's blood and CSF. Using multilocus sequence typing analysis, these strains were identified as a novel sequence type, ST-8912. Special attention is required for the meningococcal disease in military camp because the military personnels are in high risk of contact transmission.
