The authors describe the case of a 57-year-old female who developed subrachnoid hemorrhage secondary to rupture of posteriorly projecting, high placed aneurysm of the proximal posterior cerebral artry. This aneurysm was treated easily and successfully with the zygomatic temporopolar approach which was modification of the temporopolar approach proposed by Sano by detaching the zygomatic arch to get a wide and flexible operating field.

This study aimed at examining speech defects of open bite patients, which were analized in terms of formant frequency for vowels and word pronunciation length for consonants. In addition, the upper and lower lip (perioral m.) activity was tested by the EMG. The tongue force was measured by the strain gauge, and the speech discrimination test was carried out. One experimental group and one control group were used for this study and they were respectively composed of six female openbite patients and six normal-occlusion females. Eight monophthongs, two fricatives and two affricatives were chosen for speech analysis. Speeches of the above-mentioned groups were recorded and then analized by the ILS/PC-I software. Four hundred most frequently used monosyllables were also chosen for discrimination score. Openbite patients showed the following characteristics: 1. Abnormality in case of /a/, /epsilon/, /e/, /i/ F2 and /e/, /a/ F1. 2. Significantly elongated length in their pronunciation of /h/ and /Ch/ and somewhat elongated length also in their pronunciation of /s/ and /c/. 3. Significant upper lip activity according to the EMG test during pronunciation of the bilabial consonants. 4. Relatively weak tongue force according to the strain gauge measurement. 5. According to the speech discrimination test, high rate of misarticulation in case of (a) initial /p/ /s'/ and /ts'/, (b) /a/, /epsilon/, /e/, /je/, /o/, /phi/, /jo/, /u/, /we/, and /i/ (c) final /eta/.

The study was undertaken to ascertain the speech defect of patients with malocclusion, especrally of poenbite patients, by means of the spectral analysis method. The expermental group was composed of ten female openbite patients and their mean age was 13.8 yrs. The control group was also composed of ten female girls ans then mean was 13.7 yrs. As for the speech materisl, eight Korean monphthrongs ans two Korean fricatives and two affricatives were used Speeches were recorded and then analyzed by a Kay 7800 drgital sonagraph. Formant frequency level or range was used as a phonemic parameter. The results were as follows. 1. Among Vowels /a/ F1,F3, and F1/F2 showed abnormahty /o/and/omega/F2,F2-F1 and F1/F2 showed abonrmahty. 2. Among Consonants /s/and/h/ The upper and lower borders of the frequency range showed abnormahty. /f/ The lower border of the ferquency range showed abonormahty. /C(h)/ The upper and lower borders of the frequency range and concentration point showed abonormahty.

Chordomas are maligaant tumors which arise in the remnants of the embryonic notochord, and exhibit a definite predilection for the extremes of the spinal axis, the great majority arising either in the basioccipital or in the sacrococcy geal regions. Particularly, complete surgical removal is almost impossible, therefore, local recurrence after the surgical removal of this tumor is common or rule. This report describes a csse of chordoma arising sacrococcygeal region treated with block resection.

Focal cerebral ischemia was made in 20 adult cats by transorbital middle cerebral artery occlusion (MCAO) under pentobarbital anesthesia. Arterial blood gas, systemic arterial blood pressure (SABP), intracranial pressure (ICP), and regional cerebral blood flow (rCBF) on ectosylvian, suprasylvian, and marginal gyrus of the left hemisphere by hydrogen clearance were measured for 30 minutes before and 120 minutes after middle cerebral artery occlusion. Ten animals were treated with 20 mg/kg of pentoxifylline (PTF) and ten animals with 1ml/kg of normal saline as the control group for 30 minutes before and 30 minutes after middle cerebral artery occlusion. There was no beneficial effect of pentoxifylline (Trental(R)) on basal blood flow over left hemisphere before middle cerebral artery occlusion. Regional cerebral blood flow was highly significantly improved on the marginal gyrus (MG) for 90 minutes after middle cerebral artery occlusion, more remarkable for initial 60 minutes (P<0.01), and also significantly restored on suprasylvian gyrus (SSG) for initial 60 minutes by pentoxifylline (P<0.05). However, pentoxifylline failed to improve regional cerebral flow on extosylvian gyrus (ESG) which was considered dense core of infarct area due to middle cerebral artery occlusion in cat. In addition, pentoxifylline had significant hypotensive effect during intravenous administration for 60 minutes (P<0.05). These findings suggest the possibility of pentoxifylline to ameliorate hemorheological property rather than vasodilating effect in the collaterally perfused area around dense infarct.

Cytosolic estrogen receptor(ER) and progesterone receptor(PR) were studied in 18 meningiomas using dextran-coated charcol method. Significant levels of ER were found in only one tumor of the 8 male patients and four tumors of the 10 female patients. Six of the 10 tumors in women had significant PR levels, while none of the 8 tumors in men had significant PR level. Three out of four patients with multiple meningiomas had significant level of both PR & ER, whereas three and two of 14 patients with single meningioma had significant levels of PR and ER, respectively. Interestingly, the highest level of PR(215 fM/ml) was found in a recurrent, malignant meningioma. However there was no correlation between the amount of hormone receptors and patient's age, menopausal staus, peritumoral edema, location of tumor, histological type, and size of tumor. These findings raise the possibility that endocrine manipulations may be of use in the treatment of meningioma, especially in cases with multiple, malignant, unresectable or recurrent tumor.
