Purpose: The purpose of this study was to identify the effectiveness of sensory stimulation program administered by primipara on the physical growth and mother-infant feeding interaction for the first 6 months of infancy. Method: Data were collected from December 1, 2001 to June 30, 2003. A total of 35 mothers and their infants were assigned to a control(n=17) and an experimental(n=18) group. Mothers in the experimental group received education related to sensory stimulation program and administered to their infants twice a day for 6 months. Both groups were measured the weight, length, head circumference and chest circumference of infants at 6 weeks, 10 weeks, 14 weeks, 18 weeks, and 22 weeks and the mother-infant feeding interaction at 6 weeks, 10 weeks through the home visiting. Result: Compared to the control group, the experimental group had significantly larger increases in head circumference for intervention period. In addition to, the experimental group showed significantly higher score in mother-infant interaction than control group. Conclusion: These data suggested that sensory stimulation program administered by primipara may improve the physical growth of full term infant and mother-infant feeding interaction.

Purpose: This study examined the effects of a breastfeeding coaching program for mothers on growth and neonatal jaundice in late preterm infants (LPIs). Methods: This was a quasi-experimental study (non-randomized intervention) with a time-series design. The study was conducted among 40 LPIs who were admitted to the neonatal intensive care unit of a university hospital in Daegu, South Korea. In the order of admission, the first 21 infants were assigned to the experimental group, and 19 were assigned to the control group. The intervention program consisted of home- based and web-based practical breastfeeding support education for mothers across a total of 5 sessions. Infant growth was measured using body weight, length, and head circumference, and neonatal jaundice was assessed using transcutaneous bilirubin levels. Results: The likelihood of breastfeeding for infants in the experimental group at 4 weeks after discharge was the same as on the day of discharge, whereas it steadily decreased in the control group. There were significant differences in head circumference between the groups. However, weight, length, and transcutaneous bilirubin levels did not show a significant group-time interaction. Conclusion: A formal breastfeeding coaching program should be considered in clinical settings and at home within the first few weeks postpartum.

식물세포에 마(Dioscorea batatas Dence) 추출액의 전처리가 방사선 스트레스에 노출된 배양세포의 활력, 생장 및 핵 DNA 손상에 미치는 영향을 조사하였다. 마의 분획추출물 중 EtOAc 분획추출물을 식물세포에 전처리하고 20 Gy의 방사선에 노출시키면, 마 추출물을 전처리하지 않고 방사선 20 Gy만 처리한 세포보다 세포의 활력과 생체중이 20%이상 증가하였다. Comet 분석에서 꼬리부분의 길이 (T)와 머리부분의 길이 (H)를 측정하여 T/H 비율을 조사하였다. 무처리 세포와 방사선 20 Gy를 처리한 세포의 T/H 비율은 각각 1.05 및 1.68로 나타났고, head DNA 량은 각각 86.7% 및 71.3%로 무처리 세포와 방사선을 처리한 세포간에는 큰 차이를 보여, 방사선에 의한 심각한 핵 DNA 손상을 관찰할 수 있었다. 그러나 마 추출물 중 MeOH, EtOAc 및 n-BuOH 분획추출물을 식물세포에 전처리하고 20 Gy 방사선을 처리하면, T/H 비율은 각각 1.37, 1.01 및 1.10이었고, head DNA량은 81.5%, 87.6% 및 88.7%로 방사선을 처리 하지 않은 무처리 세포 수준으로 회복되었다.

This study investigated the use of multinutrient blocks (MNB) composed of 35% date syrup, 35% date syrup byproducts, 10% date fronds, 7% urea, 7% cement and 6% common salt for growing small ruminants, as partial substitute for the roughage component of the diet (Rhodes grass hay) and its effect on feedlot performance and economics of feeding. Eight growing local Omani goats and 8 sheep (each about one year old) were used in this study. Mean body weights for goats and sheep (kg), respectively were $21.1{\pm}4.5$ and $25.5{\pm}4.1$. The goats and sheep were subdivided into two sub-groups of more or less equal body weights for each species. Each sub-group in both species was either fed on 0.5 kg concentrate+ad libitum Rhodes grass hay or the same diet+restricted hay (about 0.2 kg/head/day) and ad libitum amount of MNB. Sheep significantly (p<0.05) consumed greater amounts of MNB ($36{\pm}17$g/head/day) than goats ($6{\pm}2.5$ g/head/day). Feeding of the MNB was effective in sparing about 40% of the roughage Rhodes grass hay for goats (from 240 to 140 g) and about 42% for sheep (from 252 to 146 g) or approximately 100 g/head/day for both goats and sheep. This reduction (or sparing) in the consumption of Rhodes grass hay was coupled by an improvement in daily liveweight gain (g/head/day) in both goats (from 29 to 46 by 58.6%) and sheep (from 26 to 39 by 50%) and also by an improvement in the feed conversion efficiency (g feed/g gain) of both goats (from 25 to 13.8 by 45%) and sheep (from 28.7 to 17.2 by 40%). Cost of daily consumed feeds as well as cost/kg gain (or cost of meat) were both reduced due to feeding of MNB. They were both respectively reduced by 7.5% (from 53 Baisa/day to 49) and 38% (from 1,828 Baisa/kg to 1,140). It was economically viable to feed MNBs containing date by-products and urea to small ruminants in the Sultanate of Oman.

The aims of the present study were to determine the weaning time for adoption of kittens, and to evaluate the fetal growth rate during pregnant in free-roaming cats. This study was conducted on three pregnant free-roaming cats (one feral cat and two stray cats). Radiography and ultrasonography were performed on the feral cat and on one of the stray cats. In the feral cat, fetal head diameter was measured once during pregnancy to determine the cesarean section (C-sec) time. In the stray cat, serial fetal head diameter was measured from capture to parturition. The body weight of the feral cat's kittens was measured from 4 weeks postpartum because of their wildness. That of the stray cats' kittens was measured immediately after birth. In the feral cat, scheduled C-sec was performed at predicted parturition day by measurement of head diameter, and six healthy kittens were delivered. The stray cats had five and six kittens by natural delivery, respectively. In the body weight gain of feral and stray cat's kittens, two female kittens of the feral cat lost weight rapidly after they were separated from their mother, so they were returned to their mother for 1 more week. After that, the female kittens grew up without difficulty. Body weight gain of the ten kittens born to the two stray cats consistently increased, by approximately 14 g every day, until they were adopted. The body weight of kittens born by natural delivery was on average 77.5 g greater than that of kittens born by C-sec. However, the gap decreased with time. During the stray cat's pregnancy, fetal head diameter increased by 0.042 cm every day. Maximum head size before parturition was 2.43 cm. These results indicate that the weaning time for adoption of kittens was 5-week-old postpartum.

Hyalinizing trabecular tumor (HTT) of the thyroid gland is a rare neoplasm and only less than 100 cases have been reported so far. It is characterized by hyalinizing stroma with trabecular growth pattern and has an indolent clinical course. Because of its histologic features, it is frequently misdiagnosed as papillary or medullary carcinoma in fine needle aspiration cytologic findings. The tumor is benign or low malignant potential and thyroid lobectomy is recommended for adequate treatment. We recently experienced a case of thyroidal HTT in a 57-year-old man, who presented with a right thyroid nodule that was suspicious of papillary carcinoma in aspiration cytology. We report the unique and rare disease entity with brief literature review.

Ectopic thyroid gland is a defined as thyroid tissue located in a site other than its usual pre-tracheal location. Ultrasound examination, CT scan, thyroid scan, and thyroid iodine uptake test are all valuable modalities for a differential diagnosis. Although most of cases are asymptomatic, treatment is indicated when there are symptoms related to progressive growth of mass. This article reports a ectopic thyroid cyst in the anterior neck that was similar to deep neck infection accompanied by acute airway obstruction.

Tracheostomy is a surgical procedure that is commonly used to treat upper airway obstruction. In particular, patients with head and neck cancer may require elective or emergency tracheostomy because of airway obstruction due to massive bleeding of the intraoral tumor mass and rapid growth of the tumor mass in the neck area. Here, we report four cases of tracheostomy in patients with head and neck cancer with narrowed airway space and difficulty in breathing. Based on these cases and a literature review, we recommend that oral and maxillofacial surgeons and dental anesthesiologists should cooperate closely and determine the appropriate timing to perform definitive airway management for such patients during palliative treatment, along with continuous evaluation of tumor location, risk of recurrence, and airway involvement.
