This study was attempted for clinical investigation regarding with Apgar score changing phase of newborns and their sucking power related the score and weight. The data for this study obtained from 545 newborns who were born at Dept. of obstetric WooSok Hospital, Korea University from Jan. to Sept.. 1373. It is hoped that this study will contribute to nursing care planning of newborns in nursery. The Apgar score was checked in the delivery room at 1 minute after delivery by Doctor and rechecked at 30 minutes and 1 hour after delivery by nurses. The results obtained were as follows: 1. The total newborn numbers at 1 minute after delivery were 545, at 30 minutes were 542 (3 dead) and at 1 hour were 540. The babies were divided into 3 groups by the Apgar score. The frequency of group 1 (score 1 to 4) at each times were 5.0%, 0.9%, 0.4%, group 2 (score 5 to 7) 11.2%, 4.1%, 1.7% and group 3 (score 8 to 10) 83.8%, 95.0%, 97.9%. 2. The group I was found most frequently among the cases of less than 2, 500g and group 3 was found among the cases over 2.500g. It was found that there was a tendency of delaying in recovery process of low score among the premature and low birth weight newborns. 3. The type of delivery, breech and other I e was found worst and C-Section was the second, however normal spontaneous delivery was found the best. 4. In observation of sucking power of the newborn related its score and weight, good, fair, poor marks were given. But for convenience of statistical analysis. good and fair was collected together and poor alone evaluated. The result of group 1.2 examined statistically by F.E.T shown no relation between newborn weight and sucking power. however group 3, examined by X$^2$test shown very significant relation between newborn weight and sucking power. 5. The mortality rate of newborn while they were in hospital was found 2.6% to 545 of birth and all cases of dead belonged to group 1 at 1 minutes after delivery. 64.3% of the dead was found among the cases less than 2, 500g. 6. It was found that in this observation premature and Newborn asphyxia had influence to low score at birth. Conclusively, good anthemata carr should be emphasized in order to prevent main causes of these and should avoid abnormal delivery as possible.

The suck/swallow/breathe(SSB) synchrony, serving as the earlist primary motor mechanism, is the rhythmical, coordinated pattern of sucking, swallowing and breathing. The development of an intact SSB is an important precursor for further sensorimotor and cognitive development including speech and language development, state regulation, postural control, feeding, eye/hand coordination and social/emotional development. Arousal means a neurological mechanism for preparing one's body to orienting stimulus. Its levels are regulated with an interaction of the reticular formation, the limbic system, the hypothalamus and the autonomic nervous system. General strategies such as blowing, sucking, chewing, munching and licking to effectively modulate arousal state are related to SSB. The SSB synchrony is an important treatment principle for children with sensory integration disorder and problems with the modulation of arousal. The purpose of this article is to review concepts of SSB synchrony and the underlying relation between the modulation of arousal and SSB synchrony.

Tick saliva is critically important for continuous attachment to the host, blood feeding for days, and transmission of tick-borne pathogens. To characterize the patterns of inflammatory cytokine gene expression during its attachment and blood sucking time, peripheral blood samples of rabbits infested with Haemaphysalis longicornis ticks were collected at different intervals. Blood histamine concentration was evaluated as well as gene encoding IFN-${\gamma}$, TNF-${\alpha}$, IL-2, IL-6, IL-4, and IL-10 were compared with non-infested rabbits. Blood histamine concentration of tick-infested rabbits during fast feeding time was significantly higher than that of non-infested rabbits. In both nymph and adult tick infested rabbits, expression of TNF-${\alpha}$ and IFN-${\gamma}$ genes were decreased significantly (P<0.05), while expression of IL-4, IL-6, and IL-10 were increased 1.3 to 7 folds in adult infested rabbits with the exception of IL-6 that was significantly (P<0.05) decreased in nymph infested rabbits. IL-2 was not expressed in either nymph or adult infestation. H. longicornis saliva is capable of modulate host responses through a complex correlation with histamine and Th1, Th2 mediated cytokines that suppress the inflammatory responses directed toward inflammatory mediators introduced into the host during tick feeding.

Objectives: This study was conducted to investigate the occurrence and possible risk factors of enterobiasis among children in kindergartens. Methods: A total of 3,921 children were examined from 36 kindergartens in Ulsan, Korea. The parents were asked to complete questionnaires and to detect Enterobius vermicularis infection using the anal swab technique. Results: The overall rate of being positive for E. vermicularis egg was 7.8% ranged from 0 to 29.0%. The infection rate was related to age, gender, thumb sucking, pre-medication of anthelmintics, employment status of mother and number of siblings. The risk factors significantly associated with E. vermicularis infection were gender(OR 1.628), thumb sucking(OR 1.643), pre-medication of anthelmintics(OR 0.614), employment status of mother(OR 0.574) and number of siblings(OR 0.388). Conclusion: We propose that E. vermicularis infection screening among children in kindergartens should be continued on a regular basis. In addition, more intensive control program should be developed and applied to children.

Isolation of Staphylococcus hyicus subsp. hyicus from piglets suffering from exudative epidermitis and healthy pigs was performed, and some properties of the isolates were examined. Twentry-six litters of exudative epidermitis observed in the field were sucking piglets with ages ranging from 1 to 5 weeks and most (73.1%) of these cases occurred in piglets between 2 and 3 weeks of age. Staphylococcus hyicus subsp. hyicus was isolated front 192(38.9%) of 494 healthy pigs. The rate of isolation of these organism from healthy pigs was found to vary greatly among farms at an isolation rate of 33.3% to 45.5% and this organism was isolated more frequently front sucking piglets below the age of 8 weeks than adult pigs. All of the isolates originated from the diseased and healthy pigs were positive in heat-stable DNase, Tween 80 hydrolysis, gelatinase, protease, but negative in clumping factor and hemelysin on sheep blood agar. There was no difference related to origin in the production of extracellular active substances. Typical lesions of the classic exudative epidermitis were produced by inoculation of Staphylococcus hyicus subsp. hyicus isolated from the diseased and healthy pigs. The pathogenic potentials of isolates from healthy pigs were no different from that of the isolates obtained from diseased pigs.

Three studies were conducted to determine the effect of sex on pre- and post-weaning performance of pigs. These studies were conducted in response to observations that female pigs appear to grow faster than male pigs after weaning. In addition, female pigs have been found to grow faster than male pigs when supplied with supplemental milk before weaning. The aims of the present work were to further characterise the ontogeny of sex differences growth of nursing and growing pigs. In the first study, piglets sucking 32 sows were crossfostered to produce litters of 10 boars (n=9), 10 gilts (n=l 1) or 5 boars and 5 gilts (n=12). Liveweight of the sucking pigs was then measured weekly until weaning at 4 weeks of age. In the second study, 80 boars and 80 gilts were weaned at 26 days of age and growth performance measured until 21 days post-weaning. In the third experiment, 40 boars and 40 gilts were weaned into groups of 5 pigs at either 17 or 25 days of age and pigs were weighed until they were approximately 90 kg liveweight. All-boar litters grew more slowly than the all-gilt and mixed litters such that by 14 days of age the all-boar litters were 10% lighter than the all-gilt or mixed litters (39 vs. 43.8 kg, p=0.050). The proportional difference in litter weight appeared to be maintained at 21 days of age (53.9 vs. 59.4 kg, p=0.063) but was diminished by 28 days of age (66.5 vs. 70.8 kg, p=0.28). In the second study, gilts grew more quickly than boars over the first 7 and 21 days post-weaning and as a consequence were 10% heavier than boars at 21 days after weaning (13.7 vs 12.48 kg, p=0.001). In the third study, gilts grew more quickly than boars in the immediate 7 days post-weaning (40 vs. 5 g/day, p=0.014) whereas from 7 until 35 days post-weaning there was no significant difference in growth rate (381 vs. 360 g/day, p=0.19). Gilts also grew more quickly than boars over the 14 days after being moved into the grower (631 vs. 570 g/day, p=0.013) and finisher (749 vs. 688 g/day, p=0.038) sheds. However, these differences were not maintained over the entire period in each shed. These data support the hypotheses that gilts handle the stresses of weaning and other transitions better than boars.

In the silkworm egg production, cutting of the cocoon's edge formed by silkworms forced to aid the emergence, and emergence is related to the amount of alkaloid liquid in the sucking stomach in certain varieties. In this study, there was no difference between cutting of portion and sex, and no significant between cutting of both sides and one side cocoons when comparing their emergence ratio. Expenditures and emergence ratio between both sides and one side cutting off must be studied in coming future.

Two cases of trichobezoar with unusual presentation in female children are described. The first case is a 7-year-old female with a 3-day history of abdominal pain, obstipation, and emesis. She developed intestinal obstruction and showed double bezoars in the stomach and intestine respectively. She had been in a habit of biting or sucking hairs before sleeping from infancy until 5 years of age. The other patient is a 6-year-old girl referred for an epigastric mass, emotional disturbance and trichotillomania. In spite of the psychological treatment, 4 laparotomies were necessary due to repeated recurrences.

To analyze the developmental changes in soma diameters of digastric motoneurons, wheat-germ agglutinin conjugated horseradish peroxidase (WGA-HRP) was injected into the digastric muscle and visualized the retrogradely HRP-labeled motoneurons through tungstate/tetramethylbenzidine (TMB) and following diaminobenzidine (DAB) reactions. The results obtained from Sprague-Dawley rats at postnatal days 1 (P1), 10 (P10) and 30 (P30) indicated as follows: firstly, soma diameters of digastric motoneurons showed unimodal distribution in all postnatal days examined; secondly, the period of P1 to P10 (period 1) showed about 2 times faster growth rate than that of P10 to P30 (period 2); thirdly, the smallest soma examined in each postnatal day exhibited slower growth rate with that of the largest one (increase ratio in soma diameters from P1 to P30, smallest vs. largest = 1.62 : 1.93); Finally, relative growth rates a day showed again that period 1 had faster growth rate than that of period 2. Consequently, developmental changes in soma diameters of digastric motoneurons resulted in very different growth rates between both periods. This implies that the growth of the soma is almost completing within P10 and thereafter growing slowly. The period 1 and 2 are corresponding to sucking and sucking/masticatory period, respectively. Therefore present study providing morphological changes in soma diameters of digastric motoneurons suggests that both periods and their different growth rates of the motoneurons in each period may closely be related with each other.
