The present survey was designed to find out the utilization status of korean traditional cookies and the evaluation degrees of their commercial products' quality subjects. The subjects were housewives randomly selected who lived in Seoul, Deajeon, Youngju city (Kyoung Buk Province area), and Sechon khun (Chung Nam province area). We performed this survey from November 16 to 28, 1987 by questionnaire method. The results obtained can be summarized as follows; 1) In the subjects' home, 25 kinds of Korean traditional cookies were used. All of them Youmilkwa and Kangjeong type were used more frequently than the other types and Jeonkwa, Dasik, and Suksilkwa were used scarcely. 2) Korean traditional cookies which were showed more than 20% of utilization ratio were follows; Yackwa (74.4%), Sanja (26.8%), Taraekwa (22.6%), Seban-kangjeong (21.7%). 3) On New Year's day, Korean traditional cookies were used more frequently than harvest festival day but their utilization ratio of western cookies was follows; New Year's day was 10%, and harvest festival day was 6.2%. 5) On ceremonial day, Youmilkwa and kangjeong type were used more frequently than jeonkwa, Dasik, and Suksilkwa type. 6) All of ceremonial days, korean traditional cookies were used most frequently on the 60th birth day and their utilization ratio was extremely low on the 100th day after birth, 1st birth day, and funeral day. 7) Generally western cookies were used more frequently than Korean traditional cookies on the birth day of children and adults. 8) Convinience (64.8%) was the most favored cause purchasing the commercial products but many subjects (37.0%) wanted to make the Korean traditional cookies at home. 9) All the quality properties of commercial products, taste, package, and storage property were favored but price and hygienic property were poorly evaluated by subjects. The evaluation about taste and package property of commercial products was affected by academic career (p<0.05), and shelf life was affected by age (P<0.01) significantly. And hygienic property was significantly affected by age and academic career respectively. (P<0.01).

Serial ultrasonographic examinations were performed on 9 pregnant Korea Jin-do dog from days 15 to 60 to determine the size of gestational structures throughout pregnancy. Gestational age was timed from the day of ovulation (Day 0), which was estimated to occur when plasma progesterone concentration was first increased above 4.0 ng/ml. Extra-fetal structures were measureable from days 17 to 49. Outer uterine diameter increased from $7.0{\pm}0.7$ ($mean{\pm}SD$)mm at day 17 to $54.0{\pm}2.2mm$ at day 49 and inner chorionic cavity diameter increased from $3.0{\pm}0.7mm$ at day 17 to $37.5{\pm}0.6mm$ at day 49. Uterine wall thickness increased from $2.8{\pm}0.4mm$ at day 17 to $8.3{\pm}0.5mm$ at day 49, placental thickness increased from $1.0{\pm}0.1mm$ at day 22 to $5.7{\pm}0.2mm$ at day 49 and length of chorionic cavity or zonary placenta increased from $5.5{\pm}1.3mm$ at day 20 to $52.3{\pm}2.2mm$ at day 49. Inner chorionic cavity diameter, outer uterine diameter and placental length each increased at a linear rate through day 37, after which time, each had a marked plateau in growth. Of the extra-fetal structures, inner chorionic cavity diameter was the most accurate for estimation of gestational age until day 37. Fetal structures were measureable from days l7 to 60. Crown-rump length, increased from $3.0{\pm}0.7mm$ at day 22 to $118.7{\pm}3.1mm$ at day 49, fetal body diameter increased from $4.0{\pm}0.7mm$ at day 25 to $55.8{\pm}1.7mm$ at day 60 and fetal head diameter increased from $4.3{\pm}0.6mm$ at day 26 to $29.8{\pm}0.8mm$ at day 60. Of the fetal structures, fetal head diameter was the most accurate for estimation of gestational age from day 37 until day 60.

This study investigated the effects of xylooligosaccharide on feces bifidobacteria proliferation, lactic acid concentration and lipid metabolism in healthy woman. Fourteen volunteers were randomly assigned to 2 groups : 1.4 g/day xylooligosaccharide intake group, 2.8 g/day xylooligosaccharide intake group. The duration of the study was 28 days. The amount of feces and excretion time were not affected by xylooligosaccharide intake. The color of feces changed to yellow brown, and hardness of stool and effort to evacuation were reduced by xylooligosaccharide intake. Xylooligosaccharide intake reduced the fecal pH significantly after 14 days in 2.8 g/day intake group (p < 0.05). The number of fecal bifidobacteria were significantly increased after 28 days in 1.4 g/day intake group (p < 0.05), and in 2.8 g/day intake group, the number of fecal bifidobacteria significantly increased after 14 days (p < 0.05). Water contents of feces were not affected by xyloolgosacchride intake. The fecal triglyceride and cholesterol concentrations were increased in 2.8 g/day intake group (p < 0.05), and in 1.4 g/day intake group, fecal cholesterol concentration only was increased (p < 0.05). The fecal lactic acid concentration was significantly increased in 2.8 g/day intake group (p < 0.05). Serum trigly-ceride, cholesterol and glucose concentration were significantly decreased in 2.8 g/day intake group (p < 0.05). In conclusion, xylooligosaccharide dietary supplementation may be beneficial to gastrointestinal health and lipid metabolism, and 2.8 g/day intake was more effective than 1.4 g/day intake.

LBD-001, a recombinant human interferon ${\gamma}$ produced by genetically engineered yeast as a host system, was intravenously administered to pregnant female rats (Sprague-Dawley) from day 7 to 17 of gestation at dose levels of 0.35$\times$10$^{6}$ , 0.69$\times$10$^{6}$ , and 1.38$\times$10$^{6}$ I.U./kg/day. As the control groups, hydrocortisone sodium succinate (5 or 10 mg/kg/day) was also similarly administered. Teratological effects of the test agents on fetuses and development of offsprings (F1 rats) were investigated. (1) No significant changes by the treatment of LBD-001 were observed in body weight, food and water consumption, feeding and nursing behaviors, and autopsy of pregnant or lactating mother rats. However, in hydrocortisone sodium succinate (10 mg/kg/day)-treated group, significant decreases of body weight on day 16, 18, and 20 of gestation and food consumption on day 20 of gestation and outstanding atrophy of thymus and adrenals were observed in two rats autopsied on day 20 of gestation. (2) No significant changes in resorption rate, skeletal or visceral development of fetuses, and physical or sensory development of offsprings (Fl) by the treatment of LBD-001 were detected. In hydrocortisone sodium succinate (10 mg/kg/day)-treated group, however, there were significant decreases of body weight of fetuses, delay of ossification, temporary delay of body weights of offsprings (F1) on day 1 and 3 of lactation, and increased tendency of stillborn rate and malformation rate of bone. The results show that LBD-001 at the dose of 1.38$\times$10$^{6}$ I.U./kg/day or less is not teratogenic in organogenesis of fetuses and the development of offsprings (F1). Meanwhile, hydrocortisone sodium succinate (10 mg/kg/day) seems to delay ossification of fetuses and temporarily retard the development of offsprings (Fl).

Eliminating the infecting bacteria of the root canal system and preventing reinfection must be the main objectives of all endodontic works. None of commercially available root canal sealers have the properties of desirable tissue compatibility and strong antibacterial activity. The purpose of this study is to develope an ideal root canal sealer using commercially available polyphosphate (polyP), Calgon, which is known to be antibacterial and safe. For the study. resin type AH26, zinc oxide eugenol type Tubli Seal. Ca(OH)$_2$ type Apexit as base sealers for polyP (0~3%) and para formaldehyde containing N2 as a control base were selected. Specimens (3$\times$4mm) of the sealers were prepared in a 37$^{\circ}C$ incubator for 3 and 10 days and their antibacterial activity against streptococci and black pigmented anaerobic rods was observed using an agar diffusion method. The result were as follows: 1. Among 3 day old root canal sealers. N2 as a positive control showed the strongest antibacterial effect. followed by AH26. Tubli Seal and. Apexit which barely showed antibacterial activity against the test bacteria. In contrast. 10 day old AH26 showed a greater antibacterial activity than 10 day old N2. 2. All sealer specimens showed a greater antibacterial activity against black pigmented anaerobic rods than streptococci. Three day old ones appeared to be more antibacterial than 10 day old ones except for Apexit. 3. As compared to N2, 3 day old AH26 demonstrated a similar antibacterial activity against black pig mented anaerobic rods but to a lesser extent to streptococci. Ten day old AH26 showed a greater antibacterial activity against black pigmented anaerobic rods than 10 day old N2. 4. As compared to AH26. Tubli Seal generally revealed a lower antibacterial activity but it showed a greater antibacterial activity aginst S. gordonii Challis. 5. Enhancement of antibacterial activity by polyP was more clearly observed when it was added to Ca(OH)$^{\circ}C$ based root canal sealers. Tubli Seal and N2. 6. The addition of polyP enhanced the antibacterial activity of 3 day old AH26 against S. gordonii G9B (16%) and Challis (29%), and P. gingivalis 2561 (24%) only. Moreover, polyP failed to increase antibacterial activity of 10 day old AH26 against the test strains but P. gingivalis A7A1 28(13%). 7. The addition of polyP increased the antibacterial effect of 3 day old Tubli Seal on several test bacteria including s. mutans GS 5 (50%). s. gordonii G9B (47%) and Challis (122%). and all the test strains of P. gingivalis (13~35%) except for 9 14K 1. The addition of polyP to 10 day old Tubli Seal increased antibacterial activity of the root canal sealer against most test strains. 8. 3 day old Apexit failed to show antibacterial activity. if any very little against S. mutans GS 5 and Pr. intermedia ATCC 49046. However. polyP increased its antibacterial activity by 50 and 69%, respectively. Increase of antibacterial activity of 10 day old Apexit by polyP was more clearly observed than that of 3 day old one.

The purpose of this study is to determine the effectiveness of routine meatal care on the reduction of catheter-associated urinary tract infection (UTI). The study was carried out on 30 patients with foley catheters in an intensive care unit of a general hospital from September 30 to April 1, 1998. Participants were both male and female. Data were collected from each patients by urinary specimen obtained with aseptic collection technique at the 3rd and the 7th day of the experiment after giving daily mental care with 10% betadine for periods ranging from 1st to 7th day to the experimental group but not to the control group. The results are as follows : 1. The rate of urinary tract infection within the experimental group was 0.0%, at the 3rd day of the experiment and 20.0% at the 7th day, but that of the control group was 20.0% at the 3rd day and 7% at the 7th day. There was a significant difference in urinary tract infection rate between the two groups at the 3rd day but no significant difference at the 7th day. 2. In the control group, the rate of UTI was 0.7% for male and 13.3% for female at the 3rd day, and 6.7% for male and 40% for female at the 7th day. In the experimental group, the rate of UTI was 6.7% for male and 0.0% for female at the 3rd day and 13.3% for male and 20% for female at the 7th day of experiment. There was a no significant difference between male and female. 3. By comparing the rate of UTI to the length of time the urinary catheter was in place, the longer the catheter was in place the more significant was the rate of UTI. 4. Microorganisms isolated in the control group were bacteria for 7 cases and fungus for 3 cases but in the experimental group, only 2 cases of bacteria were isolated.
