Abstract
OBJECTIVES To investigate the actual time of onset of osteonecrosis (ON) after high dose corticosteroid treatment in systemic lupus erythematosus (SLE). METHODS 72 patients with active SLE, who received high dose corticosteroid for the first time, for the development of ON at hips and knees were monitored by magnetic resonance imaging for at least 12 months. RESULTS ON lesions were detected in 32/72 patients (44%) between one and five months (3.1 months on average) after starting high dose corticosteroid treatment. No osteonecrotic lesion was newly detected from the sixth month of treatment until the end of the follow up period. CONCLUSION The findings suggested that the actual time of onset of ON in SLE is within the first month of high dose corticosteroid treatment.

Abstract
[reaction--see text] Enantiopure (arene)ruthenium compounds possessing a stereogenic benzylic alcohol functionality were stereoselectively synthesized by diastereoselective ruthenium-Cp complexation to a distinct arene face. This diastereoselective ruthenium-Cp complexation was further extended to biaryl compounds linked with a six-membered lactone bridge for the synthesis of enantiomerically pure, axially chiral biaryls.

Abstract
[reaction: see text] The axial biaryl ring system of vancomycin was stereoselectively synthesized by utilizing a planar chiral tricarbonyl(arylhalide)chromium complex. Both enantiomers of the planar chiral (arylbromide)chromium complexes, (+)-9 and ent-(-)-9, can be stereoselectively transferred to an absolutely identical key intermediate 23 for the vancomycin A-B ring system by the diastereoselective Suzuki-Miyaura cross-coupling reaction as key step.

Abstract
Sterilisation by gamma irradiation in the presence of air causes free radicals generated in polyethylene (PE) to react with oxygen, which could lead to loss of physical properties and reduction in fatigue strength. Tissue retrieved from failed total hip replacements often has large quantities of particulate PE and most particles associated with peri-implant osteolysis are oxidised. Consequently, an understanding of the cellular responses of oxidised PE particles may lead to clarification of the pathogenesis of osteolysis and aseptic loosening. We have used the agarose system to demonstrate the differential effects of oxidised and non-oxidised PE particles on the release of proinflammatory products such as interleukin-1β (IL-1β), IL-6, and tumour necrosis factor-α (TNF-α) from monocytes/ macrophages (M/M). Oxidised PE particles were shown to stimulate human M/M to phagocytose and to release cytokines. Oxidation may alter the surface chemistry of the particles and enhance the response to specific membrane receptors on macrophages, such as scavenger-type receptors.

Abstract
The bactericidal activity of two new quinolones, grepafloxacin and levofloxacin, against five strains of Mycobacterium avium was investigated in vitro. The minimum inhibitory concentrations (MICs) of these two quinolones, determined by the broth microdilution method, were comparable for all strains tested. In contrast, grepafloxacin suppressed the intracellular growth of all the strains in monocyte-derived macrophages more strongly than levofloxacin, when the cells infected with these strains were incubated for 7 days in the presence of various concentrations of the two new quinolones. To find the reason for the strengthened intracellular killing activity of grepafloxacin, we determined the ratio of the concentration of the new quinolones in the cells to that in the medium (C/M concentration ratio). The C/M concentration ratio of grepafloxacin was increased to 34.7 by 7 days, whereas that of levofloxacin at 7 days was only 12.3. These data suggested that a higher level of intraphagocytic accumulation of grepafloxacin endows it with greater mycobactericidal activity.

Abstract
To determine whether the development of steroid-induced osteonecrosis in collagen disease patients was related to hemostatic abnormality after corticosteroid administration, we examined levels of thrombin-antithrombin III complex (TAT) and plasmin-alpha2-plasmin inhibitor complex (PIC) in 32 patients who were treated with high-dose corticosteroid. All were prospectively followed for osteonecrosis, with serial magnetic resonance imaging (MRI), for at least 12 months from the beginning of corticosteroid therapy. MRI was performed on bilateral hips and knees. Of the 32 patients, 17 (53.1%) had osteonecrosis in the hip or knee. Osteonecrosis was detected on MRI at an average 3.1 months after the start of high-dose corticosteroid therapy. PIC levels were significantly higher in the group of 17 patients with osteonecrosis (ON group) than in the group of 15 patients without osteonecrosis (non-ON group) (P < 0.0001). The difference in PIC levels was most prominent 20 days after the start of the high-dose corticosteroid therapy. Moreover, the number of osteonecrotic joints was significantly correlated with PIC levels (P < 0.0001). The sustained hemostatic abnormality after corticosteroid therapy in the ON group suggests that microvascular coagulation participates in the development of osteonecrosis.

Abstract
PURPOSE To determine the prevalence of abnormalities of the acetabular labrum in asymptomatic hips by means of magnetic resonance (MR) imaging and to correlate such abnormalities with age and the portion of the labrum. MATERIALS AND METHODS MR imaging was performed in 71 asymptomatic hips that were radially sectioned perpendicular to the acetabular labrum at 30 degrees intervals. RESULTS The shape of the labrum was triangular in 80% (304 of 382) of the labral segments, round in 13% (49 of 382), irregular in 7% (27 of 382), and not identified in 1% (two of 382). A homogeneous low signal intensity was observed in 56% (212 of 382). The frequencies of labral irregularity or its absence and of high signal intensity increased both with subject age and with a more anterior anatomic labral location. CONCLUSION In asymptomatic hips, abnormal findings regarding the shape and signal intensity of the acetabular labrum can be detected by means of MR imaging. The fact that the findings vary according to age and labral portion should be considered in interpreting MR images in patients suspected of having a labral lesion.

Abstract
We present a case of a 54-year-old female with post-operative severe continuous ocular pain which occurred 3 months after retinal operation. Her general and mental conditions were good. We diagnosed it reflex sympathetic dystrophy and treated with stellate ganglion blocks (SGB) and continuous cervical epidural blocks. SGB and continuous cervical epidural blocks were effective. With increasing numbers of retinal surgery in recent years, more patients will suffer from postoperative ocular pain. We conclude that SGB or epidural block is useful for the therapy of ocular pain which can not be controlled by drugs and other therapy.

Abstract
The association of a pheochromocytoma with von Hippel-Lindau disease is uncommon. We had a family with eight patients affected by von Hippel-Lindau disease, of whom five had hemangioblastoma of the central nervous system and seven had pheochromocytoma. As other lesions, retinal angiomatosis, spinal A-V malformation and spinal hemangioma were included in this family. In this paper five hemangioblastomas, four of whom had the association of hemangioblastoma and pheochromocytoma, are presented and clinical features of hemangioblastoma associated with pheochromocytoma are discussed, comparing to the 16 reported cases that had the association of hemangioblastoma and pheochromocytoma. The mean age of our own five cases at the onset of clinical symptoms was 32.2 years (ranging from 24 to 41 years) and that of reported 16 cases was 33.9 years (ranging from 18 to 55 years). These ages are slightly younger than that of sporadic hemangioblastoma. On the other hand, the mean age at the onset of pheochromocytoma was 28.3 years in our cases and 31.0 years in reported cases. This may suggest that hemangioblastoma when it is associated with pheochromocytoma presents its symptoms several years after the signs and symptoms of pheochromocytoma are manifested. In our cases a male to female ratio was 4:1 and in reported ones it was 9:7, showing that hemangioblastoma associated with pheochromocytoma as well as sporadic hemangioblastoma is likely to occur more in male.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Ethylacetoacetate promoted the colonic and the jejunal absorption of amino acids such as L-phenylalanine and D-phenylalanine when administered in aqueous solution. Enhanced absorption of these isomers of amino acid might occur via a formation of enamine, which was observed in aqueous solution by monitoring ultraviolet absorbance at 288 nm. Since mixture of L- or D-phenylalanine and ethylacetoacetate in aqueous solution enhanced colonic absorption of cefmetazole while the solution did not affect so much on the jejunal absorption of cefmetazole compared to the colonic absorption of it, enhancing action of enamine probably produced in aqueous solution may be more effective at the colonic compartment.

Abstract
Three patients harboring glioblastoma were treated by fractionated intracavitary radiation using remote afterloading system. For this therapy, a special intracranial applicator was designed and used. Radiation schedule was planned to deliver 3000 rads to the margin of the tumor in 3 fractions over 10 days. The advantages of this treatment are that complete elimination of all unnecessary radiation exposure is possible, and that placing a radioactive source in the tumor provides maximal delivery of radiation to the tumor with relative sparing of surrounding normal brain. The method of treatment is presented and discussed with the reports of the clinical cases.

Abstract
Two adult patients with unilateral chronic subdural hematomas are reported because of the presence of dilatation of the lateral ventricle opposite the hematoma. In both cases, dilatation was limited to the contralateral atrium and the occipital and temporal horns. The selective dilatation, we believe, is explained on the basis of the anatomy of the skull base and the falx. This phenomenon may contribute to an increase of the supratentorial pressure, originally elevated by the hematoma. This characteristic finding on computed tomographic scans should be regarded as critical in cases of chronic subdural hematoma.

Abstract
The authors describe the techniques employed in three patients with basilar artery aneurysms that were treated via the transoral transclival approach. To prevent the formation of cerebrospinal fluid fistulas and the risk of consequent meningitis, complete postoperative closure of the nasopharyngeal mucosa is essential. Long-term nasopharyngeal packing and continuous spinal drainage were found to be effective in these cases.

Abstract
Two cases of delayed radiation necrosis of the brain were reported. Case 1 was a 50-year-old man who had right hemiparesis and disorientation 26 months after Linac irradiation (5,000 rad), preceded by the operation for right maxillar carcinoma. A left carotid angiogram demonstrated a left temporal mass lesion, extending the frontal lobe. Case 2 was a 41-year-old man who had previously the operation for right intraorbital plasmocytoma, followed by two times Co irradiation (6,400 rad, and 5,000 rad). He had the signs and symptoms of intracranial hypertension 36 months after last irradiation. A left carotid angiogram demonstrated a left temporal mass lesion. Both cases were treated by administration of steroid hormone, which alleviated the signs and symptoms, followed by the temporal lobectomy. Microscopic examinations showed necrosis of the brain tissues associated with hyaline degeneration of blood vessel walls and perivascular cell infiltration. The signs and symptoms of intracranial hypertension subsided postoperatively. The other thirteen cases as same as ours were collected from literature, which showed the signs and symptoms simulating a brain tumor (like a metastic brain tumor) after the irradiation to extracranial malignant tumors, and the diagnosis of radiation necrosis were made by the operation or autopsy. A follow-up for a long time is necessary, because the pathological changes in the brain may be progressive and extending in some cases, although the decompressive operations for mass lesion are excellent in result.

Anterior view of 45 cases was stored in high speed magnetic tape, displayed on CRT of our data processing system and studied of the ratio of average count for regions of interest, 2 cm x 2 cm in size, placed on the areas of lesion, the sagittal sinus and the normal brain hemispheres. In 18 pituitary adenomas, excluding acromegaly and other intrasellar lesions, 89% of cases with surgical indication for optic nerve symptoms were reported as abnormal scintigrams. In 20 craniopharyngiomas, 11 positive cases consisted mainly of solid, recurrent or thick cystic tumors. Five of 6 ectopic pinealomas and all 6 parasellar or medial sphenoidal ridge meningiomas showed positive uptake. Average counts of the regions of interest placed on tumor areas were 169.4% of normal hemispheric areas in 9 pituitary adenomas, 192.5% in 3 solid craniopharyngiomas, 192.3% in 6 meningiomas and 193.3% in ectopic pinealomas. The difference in the average ratio of the lesion count to the normal hemispheric count was statistically significant between cystic craniopharyngioma and adenoma, ectopic pinealoma, meningioma, glioma and solid craniopharyngioma, and between adenoma and acromegaly with p less than 0.005, and between solid craniopharyngioma and acromegaly, and between glioma and acromegaly with p less than 0.025. In the ratio of the lesion count to the sagittal sinus count, on the other hand, the difference of the average ratio was significant with p less than 0.005, only between cystic craniopharyngioma and ectopic pinealoma, and between cystic and solid craniopharyngioma. These facts suggested that the sagittal sinus count was unsuitable to be the standard count of an anterior scintigram to compare with basal midline count. The routine Polaroid scintigram with Tc99m pertechnetate proved their useful clinical diagnostic value for various basal midline lesions, the size of which indicated the surgical procedures. The digital analysis of anterior scintigrams supported the clinical value of the routine brain scintigram in the detection of these lesions. The ratio of the average count of the basal midline lesion to the normal brain area on the anterior scintigram presents more useful clinical information than the ratio of the lesion to the sagittal sinus count. Brain scintigram is found to be very helpful for the differential diagnosis between solid and cystic sellar tumors which is very important for the decision of surgical indications, and is not always possible by any other conventional neuroradiological procedures.
