JOURNAL FREE ACCESSPreoperative pelvic computed tomographic (CT) images were analyzed in 50 patients with rectal carcinoma to evaluate the depth of mural invasion. Firstly the rectum was inflated with air. Secondly cross-sectional CT images of the rectal carcinoma were taken, in all cases referring to lateral scout view films and barium enema films. The circle rate of the tumor was determined in the cross-sectional image. Perirectal changes on CT were evaluated where there were spiculated and nodular appearances. The circle rate correlated with the extent of mural invasion. In cases within 1/3 circle in the circle rate and without perirectal nodular appearance, more than 90% of the tumors were limited to the muscularis propria of the rectal wall. These findings were very useful for assessing suitable surgical treatment.View full abstractDownload PDF (5047K) -

JOURNAL FREE ACCESSThe author investigated a number of factors which affect regularity of counseling and/or medication in schizophrenics in an out-patient setting. A hundred and forty eight schizophrenic out-patients at a psychiatric hospital in Yamagata were examined over a period of three years. The factors consisted of age, sex, family setting, profession, place of residence, financial status, utilization of the aftercare system, insight about their illness and attitude towards drug therapy.
Most of the patients maintained good levels in the regularity of couseling and/or medication and their attitude towards therapy was unchanged throughout the course.
On the other hand, there is a statistically significant difference between the regularity of counseling and/or medication one month before readmission and at other times.
Good levels in regularity is associated with such factors as being male, being single, working conditions, financial status, insight about their illness, positive attitude towards drug therapy and utilization of aftercare system. We had great difficulty in improving the regularity of counseling and/or medication among those schizophrenic patients. But intensive intervention such as enrolling in a day care system could have a favourable effect on the regularity of counseling and/or medication.
It may be of benefit in the future to promote further development of such support systems.View full abstractDownload PDF (1886K) -

JOURNAL FREE ACCESSFrom January 1980 to February 1991, computed tomography (CT) images of 39 patients with pancreatic carcinoma who had undergone surgery at the National Cancer Center Hospital were reviewed retrospectively. The average age of the patients was 63.0 years (the range was from 45 to 78), with 19 males and 20 females. The histopathological diagnosis was tubular adenocarcinoma in 35 cases, papillary adenocarcinoma in 2 and other diagnoses in 2. The tumor was located at the head of the pancreas in 25 cases and at the body and/or tail in 12. In the remaining 2 cases, the tumor was at the head and body in one, and at the whole pancreas in the other.
The CT images were compared with the histopathological findings, and four parameters were determined to establish the histological characterization of pancreatic carcinomas in CT: density (plain CT, CE-CT) characteristics, margin of the tumor, and delayed contrast enhancement.
CT findings such as irregular margin and heterogeneous characteristics of the tumor were associated with the macroscopic type of cut surface and INF. The infiltrative cancerous extension was especially reflective of the margin irregularity of the tumor on CE-CT.
On the delayed CT scan performed on 9 patients, the low density tumor on early contrast enhanced CT became isodense with the surrounding parenchyma. According to these findings, the possibility exists that delayed contrast enhancement relate to fibrous tissue.
In conclusion, there was a good correlation between CT images and histopathological findings related to pancreatic carcinomas.View full abstractDownload PDF (5221K) -

JOURNAL FREE ACCESSFast Fourier Transform (FFT) analysis method. The subjects who had mastered a “rapid-reading” method, were classified into two groups according to theirrapid-reading achievement level: the “under-trained readers” (male 5, female 2) had already acquired the ability of smooth eye movement, but continued to use the mental phonetic process while reading. The “well-trained readers” (male 6, female 2) could understand the contents of the text without resorting to such phonetic process. All subjects were righthanded.
The tasks were designed to eliminate the artifact of the eye movement and the electromyogram as much as possible. The EEGs were recorded with twelve channels of the international standard 10-20 electrode system. The relative power value (R. P. V.) was calculated as follows:
RPV (%) = {(X. C) IN} X 100(%)
where X is the beta 1 or beta 2 power value by FFT analysis while doing tasks, C is the power value while doing control tasks, and N is the value in the resting state with the eyes open. The results were statistically analyzed by paired I-test.
The following results were obtained: In both groups; (a) the left angular gyrus was usually activate during the rapid-reading; (b) the Wernicke's center was activated only during reading with the phonetic process; (c) in the well-trained readers the activation of the right visual cortex was associated with some visual imaging during the rapid-reading; (d) in the under-trained readers, the association between the activation of the central frontal area and the rapid-reading was observed.
Thus, the following model for “reading” was obtained: Two parallel pathways seem important in the processing of the verbal information presented visually; one relates only to the left angular gyrus where the visual-verbal information is processed directly, and the other relates to the interactive pathway between the left angula gyrus and the Wernicke's center. Moreover, the visual cortex of the non-verbal hemisphere seems to play some role in understanding verbal information.View full abstractDownload PDF (2367K) -

JOURNAL FREE ACCESSThe protein with the most predominant Ca2+ binding activity in membrane fractions of the human placenta was purified to electrophorectical homogeneity. This protein was identified as the membrane bound form of calmodulin based on the immunological cross reactivity and a number of biochemical properties.
The membrane fraction of the human placenta contained 8.3% of the total cellular calmodulin activity. Approximately 2/3 of the membrane associated calmodulin was extracted by incubation with a Ca2+ chelating agent, EGTA, suggesting that this form of calmodulin is bound reversibly to membrane proteins in a Ca2+ dependent manner. However, the rest of the membrane associated calmodulin could not be extracted by EGTA treatment. The EGTA nonextractable calmodulin appears to be embedded in the membrane matrix.View full abstractDownload PDF (8083K) -
