The present study addressed the risk factors in early life for Korean preschool children that are associated with being overweight or obese.

Five fetal maxillas were obtained from the autopsy file of fetal postmortem examination, and were examined by serial micro-sections of frontal plane and horizontal plane. Especially the area around the incisive canal of the maxilla was carefully observed. The results are as follows. 1) In 5 fetal maxillas extra-dental laminas and supernumerary tooth germs which are severely malformed in shape are found in the dilated incisive canal, where prominent vessels and nerves are distributed. 2) The supernumerary tooth germs disclose almost normal histo-differentiation of odontoblast and ameloblast, and there shows relatively abundant perifollicular fibrosis in the place of perifollicular bone. 3) It is observed that the over-growth of the extradental lamina from the dental ridge of deciduous central incisor frequently tends to direct toward the incisive canal that includes prominent vessels and nerves.

PURPOSE: This study was done to explore factors relating to number of falls among community-dwelling elders, based on gender. METHODS: Participants were 403 older community dwellers (male=206, female=197) aged 60 or above. In this study, 8 variables were identified as predictive factors that can result in an elderly person falling and as such, supports previous studies. The 8 variables were categorized as, exogenous variables; perceived health status, somatization, depression, physical performance, and cognitive state, and endogenous variables; fear of falling, ADL & IADL and frequency of falls. RESULTS: For men, ability to perform ADL & IADL (beta32=1.84, p<.001) accounted for 16% of the variance in the number of falls. For women, fear of falling (beta31=0.14, p<.05) and ability to perform ADL & IADL (beta32=1.01, p<.001) significantly contributed to the number of falls, accounting for 15% of the variance in the number of falls. CONCLUSION: The findings from this study confirm the gender-based fall prediction model as comprehensive in relation to community-dwelling elders. The fall prediction model can effectively contribute to future studies in developing fall prediction and intervention programs.

BACKGROUND: Intracellular calcium overload is a common final feature of the ischemic-reperfused heart and mediates the genesis of irreversible cell damage. Reactive oxygen medabolites have been known to play and important role as toxic mediators in myocardial injuries resulting from ischemia and reperfusion. In order to investigate the mechanism of intracellular calcium accumulation in the ischemic-reperfused myocardium, the present study observed the possible contribution of the reactive oxygen metabolite to the calcium transport of cardiac mitochondria. METHODS: Mitochondrial were isolated from rabbit hearts. The effects of a reactive oxygen metabolite, H2O2 on calcium uptake and release, redox states of endogenous pyridine nucleotides and glutathiones of mitochondria respiring with succinate were observed. Calcium uptake and release were monitored by dual-wave length spectrophotometer using a calcium indicator, arsenaze III. Contents and redox states of pyridine nucleotides and glutathiones were measured by enzymatic methods using spectrofluorometer and HPLC. RESULTS: Hydrogen peroxide(10-500microM) promoted calcium release dose-dependently from CA++-preloaded mitochondria, but did not affect the mitochondrial calcium uptake. The H2O2-induced calcium release was accompanied by simultaneous oxidation of the pyridine nucleotides and decrease in the content of the reduced form of glutathione(GSH). When mitochondria were treated with BCNU(N,N=bis(2-chloroethyl)-N-nitrosourea) to inhibit glutathione reductase and so as to reduce the GSH content, there were no increase in calcium release from the mitochondria. These results may indicate that H2O2 increases the permeability of cardiac mitochondrial membrane to calcium in association with the changes in redox state of endogenous pyridine nucleotides, but not with that of glutathiones. CONCLUSION: It is suggested that the reactive oxygen metabolites induce the release of calcium from mitochondria by altering the redox state of pyridine nucleotides, and it may partly be involved in the elevation of cytosolic calcium concentration in the ischemic-reperfused myocardial cells.

OBJECTIVES: Some emotional components, such as self-esteem, depression and anxiety, have been reported to be associated with paranoia in non-clinical population and schizophrenia patients. The aim of this study was to investigate the correlation between self-esteem and paranoia in healthy controls, in ultra-high risk for psychosis and schizophrenia patients. METHODS: 34 subjects with recent onset schizophrenia, 36 subjects with ultra-high risk for psychosis, and 44 healthy volunteers participated in this study. A detailed assessment was made of the paranoia, self-esteem, depression, and anxiety. RESULTS: In all three groups, there were a negative correlation between paranoia and self-esteem, and positive correlations between paranoia and depression and anxiety. In healthy control, lower self-esteem showed a trend to predict higher paranoia, and in ultra-high risk for psychosis, this trend tern on statistically significant level, and in recent onset schizophrenia group, this correlation was disappeared. CONCLUSION: The individual who have lower self-esteem showed higher paranoia tendency under delusional level, but after formation of persecutory delusion, the tendency was disappeared. This result supports the hypothesis that persecutory delusions are a defense against negative affective process.

We examined sixty-three human embryos ranged from three weeks to eight weeks of fertilization age and 117 human fetuses from eleven weeks to fourty weeks of gestational age. Anatomical structure of developing tongue could be classified into eight developmental stages. The first is the sgage of mesial swelling of tongue primordium in the fertilization age of 28~40 days (Streeter stage 13~16), the second is the stage of lateral swelling of tongue primordium in the fertilization age of 41~46 days (Streeter stage 17~18), the third is the sgage of vertical positioning of tongue in the fertilization age of 47~53 days (Streeter stage 19~21), the fourth is the transitional stage of tongue from vertical position to horizontal position in the fertilization age of 54~56 days (Streeter stage 22~23), the fifth is the stage horizontal positioning of tongue in the gestational age of 11 weeks, the sixth is the stage of protrusion of tongue in the gestational age of 12 weeks, the seventh is the stage of maturation of tongue muscle in the gestational age of 7-10 months. The development of tongue papilla characteristically progresses into three stages. The first stage is the epithelial ingrowth for the crypt formation, the second stage is the anatomical formation of vallate, fungiform and filiform papillae, and the third stage is the differentiation of taste buds in the vallate and fungiform papillae or the formation of thick spike-like keratinization at the tip of filiform papilla. We observed that the tongue primordium mainly derived from occipital myotome developed more repidly than other oro-facial structures, so it transitionally occuied the spaces of the pharynx and the posterior nasal cavity, and directly affected the formation of palate and the growth of maxilla and mandible. Whereas the tongue papilla development showed continuous developmental sequences during the fetal period.
