The health-related habits dietary behaviors and nutrient intakes of the elderly living in Cheongju were investigated by interviews with a questionnaire from August to September in 1996. The responses of 169 free-living elderly aged over 65(male 91, female 78) were analyzed. Thirty-six percent of the subjects smoked currently, 33%, drank alcoholic beverages, and 52% exercise regularly. Exercise was mostly in the from of walking for 1/2-1 hour. Significantly higher proportions of males smoked, drank, and exercised as compared to females. Food groups eaten at every meal were examined on a 5-point scale, and the consumption scores were compared with groups according to sex, age, smoking, drinking, and exercise habits. The elderly who exercised regularly got significantly higher scores in their calcium intakes and the variety of the 6 food groups than the elderly who did not exercise. The dietary assessment data showed that the energy intakes of males and females were 81.9% and 72.8% of the RDAs, respectively. The proportions of the elderly consuming less than 75% of RDAs of vitamin A and calcium were 96.5% and 91.1% of the total subjects, respectively. Higher educational status, more pocket money and regular exercise had positive effects on nutrient intakes, while smoking and drinking among females, but not males, had negative effects. Therefore, to improve nutritional status of the elderly, intake of vitamin A-and calcium-rich food such as milk with regular exercise should be emphasized on the education program.

The Carnegie stage is widely applied in the field of human embryology, and it is more logical to analyze the embryos by this stage than CR length or menstrual age. In this study, the early development of the pancreas is studied by tissue observation and reconstruction using serial sections of 33 human embryo ranging from Carnegie stages 11 to 23. The dorsal pancreas develops from the dorsal wall of the duodenum in stage 12, and the ventral pancreas from the proximal part of the cystic primordium in stage 13 or 14 as a single epithelial thickening, but in one case, as a bilateral thickening which contains some isolated spaces. The rotation of the ventral pancreas starts in stage 15, and completes in stage 17. Surrounding connective tissue differentiates in stage 18.

We studied the intradural variations of spinal nerve rootlets in 100 cases of Korean adults. The results of the study are as follows ; 1. The incidence of intrasegmental variations (abberrant rootlets) is high in cervical segments and decreased toward lumbosacral segments. The incidence is higher in posterior rootlets than anterior, except cervical sesments. 2. The incidence of intersegmental variations is higher in posterior rootlets than anterior, and generally high in cervical and lumbar segments. 3. We divide the intersegmental variations into supernumerary rootlets, dividing rootlets, and anastomosing rootlets, and among them the incidence of anastomosing rootlets is higher. We divide the anastomosing rootlets into parallel anastomosing rootlets, uniting anastomosing rootlets, and rearrangement anastomosing rootlets. 4. The anterior to posterior anastomosing of spinal nerve rootlet is present in 4 of cases studied.

A hemagglutination(HA)-typing system has been developed for the presumptive identification of enterotoxigenic Escherichia coli(ETEC) possessing the colonization factor antigens(CFA) Seventy-seven E. coli strains from pediatric patients with or without diarrhea were examined for the mannose-resistant(MR) HA or mannose-sensitive(MS) HA of human, bovine, chicken, and guinea pig erythrocytes and their antibiotic resestances. A significant proportion(68%) of the isolates exhibited the HA pattern of NNNN(experssed in the order human/bovin/chicken/guinea pig erythrocytes), and 10% of the isolates exhibited NNSS, known as the pattern about half of enteropathogenic E. coli serogroups produced. Sixty-nine strains(88%) were resistant to one or more antibiotics; 55(80%) were reristant to four or more antibiotics. The strains showed multiple drug resistance were more higher in HA-positive strains(92% of HA-positive strains) than in HA-negative strains(76% of HA-negative strains) and all of the HA-positive strains with human erythrocytes were resistant to 4 or more antibiotics. There were no significant differences between HA patterns and antibiotic resistance in both the strains from the patients with or without diarrhea. In summary, although the causative organisms in cases of diarrhea of this study have not been established, the date herein suggested that ETEC possessing CFA which produce RRRN or NRRN HA pattern was not participated in this diarrhea.

Anti-idiotype antibody (anti-id Ab) which recognizes idiotope in the variable region of immunoglobulin (Ig) can regulate Ab production by B cells in vivo and in vitro. Although it has been reported that anti-id Ab can suppress IgM production by lymphocytes or hybridoma cells without suppression of cell proliferation, the regulatory mechanism of anti-id Ab is not completely understood. We studied the effects of anti-id Ab on the production of IgG class anti-DNA Ab by hybridoma cells, on the proliferation of cells, and on the transcription levels of Ig genes. In contrast to suppressive effect of anti-id Ab on the production of IgM previously reported by others, stimulatory effects of anti-id Ab on the production of IgG by hybridoma cells as well as the proliferation of these .cells were observed. However, little effect of anti-id Ab on the transcription levels of Ig genes was observed. These results suggest that anti-id Ab can increase Ab production by stimulation of cell proliferation. Furthermore, these results suggest that the effect of anti-id Ab on the production of Ab may be determined by the difference in class of Ab produced by hybridoma cells following the treatment with anti-id Ab.
