PURPOSE: To evaluate the morphologic characteristics and anatomical variation of the foramen ovale(FO) and its relationship with adjacent foramina. MATERIALS AND METHODS: We evaluated 305 HRCT studies of the temporal bone in patients without having any disease that might alter the foraminal anatomy. This study focused on the variations in presence, shape, size, location and relationship with each other. RESULTS: The shapes of FO were 6 types(ovoid :75.2%, pyriform, elongated, round, polygonal and figure of 8). The average size was 7.4mm 1.3 in long diameter and 4.3mm 0.9 in short diameter. The position of the posterior margin of FO in respective to the line connecting the both mandibular fossa of temporal bone was various(on the line:62.3%, anterior:30.2%, posterior:7.5%). FO had communication with the foramen spinosum (FS) in 4.1% and with the foramen vesalius(FV) in 1.9%. FV was present in 47.5%(bilateral: 26.2%, right:10.2%, left:11.1%). The shapes were round or ovoid. The distance from the midline was 18.9mm 1.7. No data showed statistically significant differences between right and left. There was no inverse relationship between the presence of FV and the size of FO. Three continuous sections in one patient showed variations in the formation of foramen ovale and foramen spinosum ;one pyriform shaped foramen ovale and one foramen spinosum on the lower section, one round shaped foramen ovale and two foramen spinosum on the midsection, assimilation of two foramen spinosum into one elongated foramen spinosum on the upper section. The canaliculus innominatus was observed in 9%. CONCLUSION: Skull base foramina of the middle cranial fossa have various shape, size, location, presence and relationship with each other. It is important to recognize foraminal varients not to misinterprete as disease.

To evaluate the structural characteristics that might be related to the clinical features noted in preeclamptic patients with focal segmental glomerulosclerosis(FSGS), we analyzed post-partum renal biopsies of 8 preeclamptic patients with FSGS (group 1) by morphometry and glomerular studied the structural-functional relationships. These findings were also compared with those from three postpartum cases with minimal change lesion(group 2) and normal age-matched women(group 3). Mean glomerular volume (MGV) in group 1 and group 2 was (2.64 +/- 0.49) x 10(6) micrometer3 and (2.56+/-0.25)x 10(6) micrometer3, respectively. MGV in both groups was significantly increased compared with that of the control group [(1.11+/-0.22)x10(6) micrometer3](p<0.0005). The volume density of the mesangium/glomerulus [Vv(mes/glom)] in the group 1 patients was significantly increased (p<0.0001) when compared with that of the group 2 and the control group patients. The increment of Vv(mes/glom) was related to both the mesangial cell proliferation and expansion of mesangial matrix. The volume density of the capillary lumen/glomerulus [Vv(cap/glom)] in group I was significantly decreased(p<0.0001) when compared with that of group 2 and the control group. Vv(cap/glom) was directly related to Ccr in group l(r=0.70, p=0.05). These results suggest that reduced capillary luminal area caused by mesangial interposition is related to the decreased glomerular filtration rate in preeclamptic FSGS.

Defining prediction variables related to meta memory for the adults in aging process has worthwhile meaning from the perspective that the produced results can be helpful to reducing the difficulty of memorizing efforts and it can also enhance quality of life of aged. This study attempted to analysis relationship between perceived health status, depression, memory self-efficacy and metamemory for the subjects of middle age and old age adults. This study was designed by adopting descriptive correlational analysis method for the 468 middle and old age adults who are living in Seoul. Samples were selected by convenience sampling. Data collection was done over I month period in june 1998. The instuments used in this study were health status measuring scale including depression measuring scale, memory self efficacy measuring scale and metamemory measuring scale which were verified for reliability. Data collected were analized by using SPSS for frequency, Peason correlation, t-test and ANOVA according to the variables character and the study purposes. Results of the study were as follows. 1. Relationship between perceived health status, depression, memory self-efficacy and metamemory. Relational analyses between perceived health status, depression, memory self-efficacy and metamemory supported the hypotheses of 1st, 2nd and 3rd(p .001) These results suggested that the aged perceived great health status then their memory self-efficacy, and metamemory showed the high scores. In the case of depression when its level became decreased metamemory was inclined to increased. Thus, it is identified that strong relationship exists between these variables. 2. Perceived health status, depression, memory self-efficacy by subject's general characteristics. Scores of perceived health status were high in the group of man compared to the group of women, and also highly educated group showed great perceived health status. Group of persons having occupation showed high score of perceived health status and low depression score. The score of memory self-efficacy and metamemory showed higher in the middle aged than the old aged. The high scores of memory self-efficacy and metamemory were found in the group of highly educated people and who have continuing education. The high scores of memory self-efficacy were found in the group of persons having their job and high metamemory scores found in the group of persons having religion. In summary, the greater perceived health status and memory self-efficacy, the more metamemory scores were likely increased and the more depression level was decreased, the more metamemory was likely increased. Also it was found that general characteristics like educational level, continuing education and religion influenced the metamemory of the aged. Therfore, prevention the aged from getting depression and activation of health promotion are needed to delay time of memory loss.
