PURPOSE: To evaluate the size of normal pons and cerebellum in vivo and the change in size according to age, and to compare those with measurement of the diseased pons and cerebellum. MATERIALS AND METHODS: 121 normal adults(M:F=54:67), 5 patients with OPCD and 19 patients with WallerJan degeneration were studied. The normal group was divided into 5 subgroups according to the age (ranged from 20 to 72 years). 1.5T GE Signa MR unit was used. On axial plane, the AP(A) and transverse(B) diameters of the pons, the size of the middle cerebellar peduncle(C), and transverse diameter of the posterior fossa(D) and the cerebellum(E) were measured. On midsagittal plane, the longitudinal(F) and AP(G) diameters of the basis pontis were measured. The ratios of E/D and F/G were calculated. The student t test was used for statistical analysis. RESULTS: C, E and F/G were 15.5mm+/-1.3, 99.8mm+/-4.3 and 1.63+/-.10, respectively. F/G, H/I, and H/J were larger in male(p<.01). All data of the pons showed no statistically significant differences among age groups. E of the seventh decades was shorter than that of the third decades(p<.05). C(12.7 mm+/-1.4) in OPCD and F/G(1. 81+/-.10) in Wallerian degeneration(p<.01) showed the most significant differences when they were compared to the normal. CONCLUSION: Although the cerebellum decreased in size with age, the pons maintained its size up to eighth' decades. The measurement of middle cerebellar peduncle on axial plane (C) and the ratio of basis pontis on midsagittal plane (F/G) were important in the evaluation of OPCD and WallerJan degeneration, respectively.

Superficial gastritis has been classified as a type of chronic gastritis, since a report of Schindler in GASTRLTIS, 1947. Howev~er, Benedict reported that superficial gastritis is only acute gastritis or shows normal mucosa histologically. The com mon endopical findings of chronic superficial gastritis were adherent mucus, edema, redness. The common redness which were encounterd are patchy redness and comb-like redness(Kammrotung). We studied the relationship between the redness of superficial gastritis and acute inflammatory changes histologically. Each case of superfieial gastritis was biopsied to redening and non-redening mucosa respectively. We collected 24 cases with 48 biopsy specimens. The results are as follows: Acute inflammatory changes were found only one case in redness and none in non-redness groups. There was no difference in acute inflammatory changes in two groups. The degree of mucosal atrophy were 62.5%, 66.7% in normal mucosa, 12.5%, 16.7~% in mild atrophy, 25%, 12.5% in moderate atrophy, 0%, 4.l% in severe atrophy with respect to redness and non-redness mucosa respectively. There was no difference in degree of mucosal atrophy in two groups. Mucosal atrophies were higher in older ages above 41 years old than below 40 and with increasing age, there was increasing tendency of mucosal atrophy. In conclusion, There was no relationships between mucosal redness and acute in flammatory changes histologically and also between mucosal redness and degree of atrophy.

Arterial hypoxemia in the postoperative period is of particular importance hecause it may delay recovery, exacerbate organ dysfunction, and contribute to motality. Oxygen supply during recovery period is to prevent the complications attributed to hypoxemia, including confusion, cardiac arrythmia, reactive pulmonary hypertension, lactic acidosis and tissue death. A low flow oxygen supply device, O2-Cap, is used to supply oxygen in postoperative patients. However, it was hypothesized that increase of inspired oxygen fraction (F1O2) in an O2-Cap is less than that in a T-Piece with an expiratory limb served as a reservoir. The purpose of this study was to compare the effects of O2-Cap and T-Piece on the increase of arterial tension (PaO2) during early postoperative period. In a prospective study, we measured vital signs, PaO2, and arterial carbon dioxide tension (PaCO2) in 24 adult patients (ASA class I or II) breathing room air in the operation room. After aMominal surgery, they were transferred to the recovery room with the endotracheal tube (intemal diameter, 7.5 mm) whose cuff is deflated. We devided the patients into two groups in the same number. Group C received O2 of 5 1/m via an O2-Cap and group T via a T-piece. Postoperative values were obtained at 5 min, 30 min, and 60 min in the recovery room and were compared between two groups. Preoperative values were served as controls in each group. Vital signs were similar in the two groups. PaCO2 in both groups maintained normal ranges. PaO2 in group C increased significantly to 132.5+/-28.1 mmHg, 134.7+/-26.8 mmHg, and 136.7+/-23.6 mmHg at 5 min, 30 min, and 60 min after operation, respectively, compared with preoperative value, 99.7+/-10.0 mmHg (p<0.05). Group T also showed a significant increases in PaO2 from 102.4+/-18.2 mmHg, preoperatively to 223.1+/-56.1 mmHg, 267.0+/-90.0 mmHg, and 249.8+/-76.5 mmHg at 5 min, 30 min, and 60 min after operation, respectively (p<0.05). PaO2 in group T increased more than that in group C during the same period after the operation. It is concluded that T-Piece with a reservoir increases PaO2 more than O2-Cap andmaintains normal range of PaCO2 without hemodynamic instability. Therefore it is expected that T-Piece with reservoir of 70 ml is safe and effective in spontaneously breathing intubated patients for oxygen supply during postoperative period.

Tooth is the most important element in esthetic consideration on facial area. Tooth alignment which is in harmony with gingiva, lips, and face is also key element. The purpose of this study was to give a clinical discipline for restoration of gingival contour, which contains a ratio of maxillary 6 anterior teeth, research for gingival contour etc., in case of rehabilitation of maxillary anterior teeth. 300 Dankook university dental school students ,who is their twenties and free from periodontitis, participate in this study. The result was from each 70 males and females who had normal occlusion and tooth alignment. Length, width and length/width ratio of maxillary 6 anterior teeth were 0.74-0.81 in male, 0.81-0.84 in female. There was significant difference between male and female. The most deepest position of gingiva in maxillary central incisor and canine was located in distal part of teeth and maxillary lateral incisor was middle portion. In maxillary central incisors, gingival line of the most deepest point appeared significant difference between male and female (p<0.01) whereas there was no difference in lateral incisors and canines. Distance between interdental papilla apex and the most deepest portion appeared significant difference beween male and female. Distance of the deepest positon of gingiva is statistically significant except maxillary central incisors and lateral incisors. Standard deviation and mean of the width of labio-lingual were measured in cervical area and there was a significant difference both male and female.(p<0.01) From this result, we could get the mean of maxillary anterior gingival line and these results have great value in clinical guidance in studying maxillary anterior teeth.

Dental porcelain is one of the materials of choice for restoration where esthetics is of concern, but has a considerable potentials of wear. The wear of enamel is variable when opposed by different porcelain systems and surface conditions, and the exposed dentine and opaque porcelain due to clinical failure is expected to have high potentials of wear. The purpose of this study was to investigate the wear effects of self-glazed, polished incisal porcelain, polished dentine and opaque porcelain against human enamel in the laboratory by use of a pin-on-disk type wear tester. 4 types of dental porcelain(Vita-omega, Ceramco-II, Vintage powder, Vita-alpha of In-Ceram system) and type IV gold alloy as cotrol group were used for test specimens. Intact buccal cusps of maxillary premolar were used for enamel specimens, and the cusp converged to a point and was devoid of visible abrasion, caries, decalcification. The upper part was the cusp of a maxillary premolar and the lower part was a porcelain specimen. The enamel wear was determined by weighing the cusp before and after each test. Surface profilometer was used to quantitate wear of the porcelain specimens. Vicker's hardness tester was used to evaluate the surface hardness of test specimens. The SEM was used to evaluate the wear surfaces. The results were as follows : 1.Self-glazed porcelain produced more enamel wear than polished porcelain, especially the enamel wear of Vita-alpha self-glazed porcelain was 3.2 times more than that of other groups. 2.Opaque porcelain produced least porcelain wear, Vita-alpha self-glazed porcelain produce greatest porcelain wear, but there was no statistically significant difference between the groups(p>0.05). 3.The enamel wear of dentine porcelain was 3.8 times more than that of polished inisal porcelain(p<0.05), and the enamel wear of opaque porcelain was 1.9 times more than that of polished inisal porcelain, but there was no statistically significant difference between the groups(p>0.05). 4.Overglazed porcelain produced less enamel wear than self-glazed porcelain, and more enamel wear than polished porcelain, but there was no statistically significant difference between the groups(p>0.05). 5.The hardness number of Vita-omega dentine and Ceramco-II opaque porcelain was larger, but that of Vintage dentine and Vita-alpha self-glazed porcelain was similar to other groups. 6.Examination of SEM photographs revealed that overglazed porcelain had smoother surface than self-glazed porcelain, and self-glazed porcelain had smoother surface than polished porcelain. Much polishing scratches and larger porosities were observed on the opaque porcelain specimen, and much polishing scratchess and small porosities were observed on the dentine porcelain specimen.
