A study on branching patterns of middle hepatic artery was performed in 109 patients with A-P and oblique view hepatic angiogram, which refered to size and location of quadrate lobe in CT and SMA portography We could analyze the branching patterns of middle hepatic artery (MHA) in 100 among the 109 patients. MHA arising as a first branch of left hepatic artery was the most common pattern (50%), and MHA arising from proper hepatic artery separately one from left hepatic artery was the next common pattern (35%). MHA originating from left gastric artery, or from anterior or posterior of the right hepatic artery was seen. MHA WAS not found as an accessory or replaced artery except as replaced common hepatic artery.

Congenital agenesis of the right lobe of liver is a rare anomaly and only 33 cases have been reported. CT showed absence of the right lobe of liver and compensatory hypertrophy of the other lobe. We report the CT findings of a new case of this anomaly with a review of the literatures.

Subcutaneous angiolymphoid hyperplasia is an uncommon disease characterized by eosinophilia, proliferation of the capillary vessels and lymphoid tissue and infiltration of the inflammatory cell, especially eosinophils. The etiology of the disease are obscure, but probably trauma, lower grade infection, nervous factor & hormonal status etc. The predilection sites are face, ears, scalf & neck, but rarely reported in the extremities. We experienced a case of subcutaneous angiolymphoid hyperplasia of the inguinal region and anteromedial side of the proximal thigh in a 10 year-old man who complained pain and tenderness on the above region. The patient was treated by excision with satisfactory result.

The theoretical advantages of spondlylolisthesis reduction-fixation are substantial, but some questions such as excessive risk and morbidity relative to in situ fusion remain unresolved yet. This study included 10 consecutive patients(2 male, 8 female) who underwent posterior lumbar interbody fusion(PLIF) with transpedicular instrumentation(AKITA pedicular screw system) over the past six menths from July to December 1993. All patients were isthmic type, adult(between 30 and 57) and between grades I and II. Claudication was the most common symptom. All patients were operated upon by one surgeon(C.K.P.) and follow-up was conducted through patient interviews and examinations, both clinically and rediologically. The patients were followed postoperatively from 6 to 12 months. There were no neurologic complication related to the procedures. The clinical outcomes assessed more than 6 months postoperatively were as follows:improvement, 9/10;stationary 1/10. Radiologically, the mean reduction rate of slippage(preoperative percentage slip-postoperrative one/preoperative one x100) was 4.3% and all patients developed solid fusion. In conclusion, patients who underwent PLIF supplemented with transpedicular fixation had good overall clinical and radiological outcomes without significant neurological complications related to PLIF or screw placement.

The cerebroprotective effects of mild to moderate hypothermia(about 32degreesC) in brain ischemia have been well established. Taking into consideration of potential deleterious systemic effects of total body cooling, selective brain cooling(SBC) can be considered as an alternative mean, and recently the protective effects of SBC in focal cerebral ischemia have been reported. However, there has been no attempt to draw a comparison of antiischemic and systemic effects between systemic hypothermia(SH) and SBC. The present study investigates the effects of SH and SBC on the physiological variables, neurological outcome, and the volume of brain infarction and edema, and compares each other. In thirty adult male Sprague-Dawley rats weighing 300-400g, permanent middle cerebral artery(MCA) occlusions were performed. Five groups of animals were studied; group 1, normothermic control(n=6); group 2, systemic hypothermia for 30min(n=6); group 3, selective brain cooling for 30min(n=6); group 4, systemic hypothermia for 60min(n=6); and group 5, selective brain cooling for 60min(n=6). In the hypothermia groups, active cooling was performed 15min following MCA occlusion. During the experimental procedures, the physiological variables such as mean arterial blood pressure and blood gases were continuously monitored. Twenty-four hours following MCA occlusion, the rats were sacrificed. Eight predefined coronal sections were stained with hematoxylin-eosin and the volume of ischemic damage and edema was computed. The results are as follows: 1) There were no differences in the physiological variables between SH and SBC groups. 2) In the hypothermia groups, neurological outcome was much better(p<0.05) than that in the control. 3) The volume of ischemic damage was significantly reduced to 49.2%(p<0.05) in group 4 and 26.7%(p<0.05) in group 5, compared to group 1. 4) Ischemic brain edema was significantly attenuated in group 4(23.6%; p<0.05) and group 5(7.8%; p<0.05), compared to group 1. These results reveal that systemic hypothermia may exert more beneficial effects upon focal cerebral infarction without significant systemic complication than selective brain cooling.

Before the 1970s there was no way to quantify the severity of head injury in groups of patients, but over the last two decades, medical care of the head-injured patient has evolved to a level at which clinical management decisions are based on actual measurement of relevant physiological variables and application of sound scientific principles. One of the most important reasons of such a progress is developments in medical technology. The technology has developed in a manner that now allows improved imaging of the brain as well as accurate measurement of variables such as intracranial pressure, cerebral blood flow, and brain electrical activity, all of which combine to greatly enhance the clinician's ability to monitor the injured brain. The author can not provide all the informations of advances that have taken place, or a comprehensive description of state-of-the-art technology hear, because of limited spaces. It is only hoped that this paper would afford a useful reference for those seeking newer concepts in diagnosis of head injury.

Since Teasdale and Jennet published a method that had been evolved in Glasgow for assessing the so-called "conscious level" in 1974, the method has undergone extensive evaluation, has been adapted widely and has come to be known as the "Glasgow Coma Scale". However some investigators raised a question about interpretation of the scale in argument, particularly in terms of analysis of prognosis. It may be indispensable for clinicians and investigators to come to an agreement in interpretation of each other's investigational result with the same idea about "Glasgow Coma Scale". So the authors now review some of the factors that contributed to the design of the scale, how it has withstood the test of both scientific study and practical usage, and also to set into context its offspring, the "Glasgow Coma Scale".
