Chicken calvarial bone is known to contain various cell types, but their exact composition is unknown. By characterizing the chicken calvarial bone biochemically, it can be used to study biochemical, histochemical actions of bone cells in general. Calvaria of I8-day-old white leg horn embryo was aseptically dissected and bone cell populations were isolated by sequential enzymatic digestion. Histochemical study for osteoclast-like bone cell population was performed with tartrate resistant acid phosphatase(TRAP) stain and for osteoblast-like bone cell population, alkaline phosphatase(ALP) stain was performed. Biochemical study for osteoblast-like bone cell population was performed using alkaline phosphatasetal.P) assay. Following conclusions were obtained from this study. 1. TRAP positive multi and mononuclear cells were mostly observed in group I and II, indicating that osteoclast-like bone cell population is mostly found in these groups. 2. All the cultured groups showed almost equal ALP activities and were positive for ALP stain, indicating that osteoblast-like bone cell population is evenly dispersed in all culture groups. 3. Experimental group treated with I,25(OH)2D3 showed increase in ALP activity in contrast to the control group, confirming previous studies that I,25(OH)2D3 increases ALP activities in vitro bone cultures. 4. Results from von Kassa's stain indicated that in vitro bone formation had occured after 3 weeks of culture with beta glycero phosphate.

The purpose of this research is to analyze the effects of aerobic exercise on body composition, cardiopulmonary function, serum lipid level and antioxidants of obese and normal college female students. The subject group was made up of 13 normal students (below 30% body fat ratio ) and 12 obese students(above 30% body fat ratio). After a pretest, the subjects were given an 8-week aerobic program. Then the subjects were given a posttest and analyzed of body composition, serum lipid level, antioxidants and cardiopulmonary function after the 6th and the 8th week of the program, The program schedule was made up of 4 days per week, 60 minutes per day. Test includes B. W., subscapular and triceps subcutaneous fat thickness. change of respiratory gas, and two blood sampling before treadmill exercise and post all out state, which analyzed serum lipid and antioxidants. The subjects performed treadmill exercise starting with 4km/hr of walking and then gradually increase the speed of 1km/hr per minute until all out state. The obtained data were analyzed using SAS program. The statistical methods employed here were one-say ANOVA with repeated measure, Duncan Multiple range test, paired-t test and t-test. The test results and conclusion go this research were as follows. 1. The effects of aerobic exercise on body composition were as follows ; Percent body fat was significantly reduced 6 weeks after the program and lean body mass was significantly increased 8 weeks after the program in both groups(obese group : F=3.44 P=.044, normal group: F=3.30 P=.048). subscapular skinfold of the obese group showed a remarkable decrease after the 6th week(F=4.3 P=.21) triceps skinfold of the normal group showed a remarkable decrease after the 6th and 8th week(F=4.55 P=.017) compared with readings before the aerobic program, the aerobic program made a bigger difference concerning body fat, lean body mass, subscapular skinfold in the obese group than in the normal group(t=2.41 P=.024 p=.025, t=2.43 p=.028). 2. The effects of aerobic exercise on cardiopulmonary function were as follows : Maximal O2 uptake/kg was significantly increased 6 weeks after the program in the obese group(F=3.20 P=.054), but not much difference was observed in the normal group. maximal pulse rate was significantly reduced in both groups after 6 weeks of the program(obese group : F=2.77 P=.087, normal group : F=7.17 P=.001). 3. The effects o aerobic exercise on serum lipid level were as follows : In a resting period, total cholesterol, Triglyceride, and LDL-cholesterol were slightly higher in the obese group than in the normal group, but HDL-cholesterol was higher in the normal group. But with the aerobic program, total-cholesterol, Triglyceride, LDL-cholesterol were reduced gradually and HDL-cholesterol got increased in both groups, but not much change was noticed in the normal group. However, in the obese group, serum HDL-cholesterol level got increased significantly(F=5.12 P=.012). 4. The effects of aerobic exercise in serum antioxidants were as follows ; In a resting period, the obese group's serum Free Radical and GSSG content were higher than the normal group's and the normal group's serum GSH content was higher than the obese group's. After 6 weeks of the aerobic program, Free Radical was reduced significantly in both groups(obese group : F=13.87 P=.000, normal group: F=18.60 P=.000) In the obese group, 8weeks after the program, GSH was increased significantly(F+13.78, P=.000). In the normal group, 6 weeks after the program GSH was reduced but increased again after 8 weeks(F=6.07 P=.005). Plasma GSSG was significantly increased after 8 weeks of exercise in both groups(obese group: F=19.75 P=.000, normal group: F=2.42 P=.000). Compared with readings before the aerobic program, the aerobic program made a bigger difference serum GSH in the normal group than in the obese group(t=3.37 p=.003) As this results shows, It is known that the regular aerobic exercise improves cardiopulmonary function, body composition, serum lipid effectively and through the serum Free Radical reduction and antioxidant system activation, oxidant stress was suppressed. This effect was high in the obese group than in the normal one. At least 6 weeks exercise period need for improvement of body composition, cardiopulmonary function and activation of antioxidant system, This result suggest that improvement of serum lipid profile was needed longer than 8 weeks exercise period.

BACKGROUND: In women, the prevalence of depression is known to be more than twice as high as in men. Because many depressive women complain of their somatic symptoms instead of neurovegetative ones, many cases of depression have been misdiagnosed. Women also tend to use medicine more frequently than men do to manage depression. So we investigated the relationship between somatic symptoms and drug use in housewives for better management. METHODS: From 1st. March to 31st. March in 1996, the prepared questionnaires were presented to housewives living in the area of Kyung-ju city, who responded the questionnaires under direct interview. The questionnaire was composed of two parts. One part included demographic data, somatic complaints, drug use, places of drug purchase, current diseases that had been diagnosed by doctors. The other included Korean standard Beck Depression Inventory-questionnaire. The subjects were divided into two groups by BDI score(21 point), which was the cut-off point for depression in Korea. The relationships of somatic symptoms and drug use between the two groups were analyzed. RESULTS: There were 110 housewives who had depressive trends among 569 respondents. In general characteristics, there was significant difference between the two groups except the item of religion. In the items of somatic symptoms, there were more somatic symptoms in the group of high BDI score(>_21) except fatigue(P<0.01). More drug users were found in the group of high BDI score(>_21) (P<0.05). In the group of high BDI score(>_21), there was definite correlation between the items of somatic symptoms and drug use. There was no difference between the two groups in the item of drug purchase site. The most common site of drug purchase was the drug store in both groups. CONCLUSIONS: Depressive housewives complained of more somatic symptoms and more often used drugs as well.

Due to an increasing interest in esthetics and concerns about toxic and allergic reactions to certain alloys, patients and dentists have been looking for metal-free tooth-colored restorations. Recent improvement in technology of new all-ceramic materials and composite materials has broadened the options for esthetic single crown restorations. The aim of this investigation was to study the fracture strength of the metal-free posterior single crowns fabricated using two recently introduced systems, Empress 2 ceramic and Targis-Vectris. Forty premolar-shaped stainless steel dies with the 1mm-wide circumferential shoulder were prepared. Ten cylindrical crowns having a diameter of 8.0mm and total height of 7.5mm were fabricated for each crown system respectively (PFM, Empress staining technique, Empress 2 layering technique, and Targis-Vectris). The crowns were filled with cement and placed on the stainless steel dies with firm finger pressure. The crowns were then stored in distilled water at room temperature for 24 hours before testing. The crowns were tested for fracture strength in an Instron universal testing machine (Instron 6022). With a crosshead speed of 1mm/min the center of the occlusal surface of the crown was loaded using a 4mm-diameter stainless steel ball until fracture occurred. The fracture surfaces of the crowns were gold coated and examined using scanning electron microscopy (Jeol JSM-840 Joel Ltd., Akishima, Tokyo, Japan). Within the parameters of this study the following conclusions were drawn: 1. The mean fracture strength for PFM crowns was 5829(+/-906)N; for Empress staining technique the fracture strength was 1697(+/-604)N; for Empress 2 Layering technique the fracture strength was 1781N(+/-400)N, and the fracture strength for Targis-Vectris was 3093(+/-475)N. 2. The fracture strength of the PFM crowns was significantly higher than that of the Empress 2 and the Targis-Vectris crowns (P<0.05). 3. The fracture strength of the Targis-Vectris crowns was significantly higher than that of the Empress 2 crowns (P<0.05). 4. No statistical difference was found when Empress staining technique was compared with Empress 2 layering technique. 5. The SEM image of fracture surface of Empress 2 crown showed a very dense microstructure of the lithium disilicate crystals and the SEM image of fracture surface of Targis-Vectris crown showed indentations of Vectris and some fibers torn off from Vectris.

This investigation evaluated the fracture toughness (KIC) of eight currently available core materials, and relate the fracture toughness value to fractography analysis and surface characteristics using a atomic force microscope (AFM). Single-edge notched (SEN) test specimens (n=10) and compact tension (CT) test specimens (n=10) were prepared conforming to the ASTM Standard E-399 for a high copper amalgam, three composite core materials (Core-Max II, Core Paste, Bisfil Core), two reinforced composite core materials (Ti-Core, Ti-Core Natural), a resin-modified glass ionomer core material (Vitremer), and a conventional glass ionomer core material (Ketac-Molar). The specimens were tested with an Instron Universal Testing Machine. The maximum loads were measured to calculate the fracture toughness (KIC). Thereafter, fracture surfaces of SEN specimens of each material were investigated for fractography analysis using scanning electron microscope. And, disc-shaped specimens with 1mm thickness were fabricated for each material and were investigated under AFM for surface morphology analysis. The results were as follows : 1. Bisfil Core showed the highest mean fracture toughness regardless of test methods. 2. For the tooth-colored materials, Ti-Core Natural exhibited the highest fracture toughness. 3. Ketac Molar showed a significantly low fracture toughness when compared with the amalgam and the composite resin core materials (p<0.05). 4. The fracture toughness values obtained with the single-edge notched test, except Ketac Molar, were higher than those obtained in the compact tension test. 5. SEM revealed that the fracture surface of high fracture toughness material was rougher than that of low fracture toughness material. 6. AFM revealed that the surface particles of the composite resins were smaller in size, with a lower surface roughness than the glass ionomer core materials.
