The purpose of this study was to investigate the distribution of nerves in the rat circumvallate papilla by each developing stage. The distribution of nerves in the rat circumvallate papilla were investigated by means of immunohistochemistry for detection of calcitonin gene-related peptide(CGRP). The results were as follows : CGRP-immunoreactive(IR) nerve fibers entered the base of the papilla laterally to form a subepithelial plexus. On the 1st postnatal day, the bead-like appearance, typical appearance of CGRP-IR nerve fiber, was seen, but from the 5th postnatal day the bead-like appearance was seen less clearly and nerve fibers looking like a line were often observed. Mature taste buds having taste pores were first seen at the 10th postnatal day and then, increased markedly after this stage. CGRP-IR nerve fibers entering the epithelium were rarely seen on the 5th postnatal day but they increased in number on the 10th postnatal day when mature taste buds having taste pores were firstly observed and then on the 15th postnatal day, they were observed abundantly throughout entire epithelium. But from the 20th postnatal day, the nerve fibers in the lower two-third of the trench wall in which taste buds exist decreased but on the top surface and upper one-third of the trench wall the nerve fibers were observed limitedly.

브로일러를 생산하는데 있어서 환기가 매우 중요한 요인의 하나가 되는 것은 말 할 필요도 없다. 그러나 브로일러 농장의 실태를 볼 때 환기조작이 적절하지 않은 예가 있는 것으로 보인다. 중요한 것은 기상조건의 변화를 예측해 보는 것이 필요한데 이는 환기가 브로일러의 발육과 건강을 위해 이상적인 환경을 만들어 내는데 중요하기 때문이다. 사내환경이 부적절 할 때 브로일러의 발육저하가 발생되며 성장률도 나빠지고 사료효율도 저하된다. 또 깃털상태도 좋지 않아 상품의 질이 떨어져 결국 수익저하로 이어진다. 현재 국내에서 사용하고 있는 브로일러 계사는 환기가 좋지않은 경우가 많이 보이는데 커텐을 사용할 때 자연환기를 이용하는 계사에서는 주의깊은 점검을 필요로 하고 결국은 보다 안정된 환경을 공급해 주는 것이 필요하다. 현재 양계장에서 활용하고 있는 강제환기법은 기본적으로 팬을 이용해 계사내의 공기유동을 조정하는 것으로 되어 있으나 강제환기에는 계사내에 공기를 끌어들이는 방식과 계사내의 공기를 외부로 배출시켜 나가는 방식이 있다.

Trauma to the primary teeth may have an effect on the successive permanent teeth. Thus, the treatment plans should be focused on safety of their permanent teeth. The degree of developmental disturbances in those permanent teeth depends upon many factors including the age of the children, developmental conditions of the affected teeth, types and severities of trauma and time interval from the moment of trauma to the initial treatment the patients received. The complications of the effected permanent teeth vary from the mild enamel hypoplasia to the premature finishing of teeth development. In this study, children whose ages were 33 months, 5 years, and 26 months presented the developmental disturbances to their permanent teeth, which resulted from the trauma to the primary teeth: the intrusion, the avulsion, and the subluxation. There showed a mild complication in the case of subluxation resulting in enamel hypoplasia, but, the more severe complication of the root dilacerations occurred in the case of intrusion. Furthermore, the 5-year-old patient whose primary dentition was near in transition period to the permanent one, the more complicated problem such as stop of root development of the permanent teeth was resulted from the avulsion. Thus, one should assume that the types of trauma and the age of the children at the moment of trauma have different effects on those successive permanent teeth. In conclusion, when the trauma that causes changes in the position of primary teeth happened, it is important to arrange an appropriate treatment procedure considering the types of trauma and the developmental conditions of the permanent teeth.

The effect of administration of red pepper Capsicum annuuml on the growth rate and resting metabolic rate in male chickens was investigated while varying the dose of red pepper. Growth of the chickens fed the rations containing small amount of red pepper(0.1% or 0.5%) was significantly enhanced. In the chickens given the ration containing 1% of red pepper, which showed the result similar to that of control chickens fed the ration without red pepper, retarded growth was seen as compared with the growth of the chickens fed the rations containing small amount of red pepper. Chickens administered the rations containing large amount of red pepper (5%, 10%, 60%) showed significantly retarded growth as compared with the growth of control chickens. There was no effect on the resting metabolic rate of chickens when administered varying amount of red pepper. The oxygen of resting chickens was varied $9.0-10.5ml/kg^{0.75}/min$ and rectal temperature was varied within the normal range ($41-42^{\circ}C$).

This study was designed to explore whether the temperament of a child influences the physical growth. The Korean version of the Parent Questionnaire for Children developed by Thomas, Chess and Korn was applied to 395 Korean children whose ages ranged from 3 years to 7 years. Simultaneously the height and the weight were measured for each child and converted into percentile scale according to the Growth Curve and the Weight Percentile Table for the Height of Korean children. Statistical analysis was performed among 9 temperamental categories, height and weight percentiles for the age and weight percentiles for the height using the first-order partial correlation analysis, controlling for the familial mean income per month. Results showed that the more temperamentally difficult a child is, the lower weight he has when compared with the children of the same age or the same height. Although there were some differences, the tendency of the above findings was maintained both in male and female children. These results show that the temperament may influence the physical growth as well as the psychological development.

Noonan syndrome (NS) is a developmental disorder characterized by dysmorphic facial features in association with short stature, mental retardation and congenital heart disease. NS may be sporadic or inherited as an autosomal dominant or recessive trait. The children with NS usually have ocular hypertelorism, downslanting palpebral fissures, low-set ears and a webbed neck, chest deformity. In addition, oral features include micrognathia, high arched palate, dental malocclusion, dental anomalies and rarely, cleft palate. The phenotype of NS bears similarities to that of Turner syndrome. However, NS occurs in both males and females with a normal sex chromosome 46, XX and 46, XY constitution. This case presents the intermittent treatment of an 8-year-old girl who was referred from a local clinic for the extraction of supernumerary teeth and treatment of dental caries. The focus of this case report is the oral aspects on NS and particularities of the dental treatment in subjects affected by this genetic disease.

This experiment was conducted to investigate the effect of restricted feeding to pullet on growth pattern and body composition. Conventional diets(C) was formulated by NRC recommendation, and one of restricted diet started from seven to seventeen week of age(T1), and another started from twelve to seventeen(T2) with adjusted eighty percentage amount of conventional diet. Body weight decreased with starting restriction of feeding comparing to the C(P＜0.05), but reached to similar weight in all treatments at twenty week regardless restriction. All of birds started to lay egg around 1,400 to 1,450gram of body weight though the age was in order of C, T2 and T1. Fat contents of restricted group in the body were less than that of C around one thousand gram of body weight. And the tendency of body fat was similar to the first egg. After twenty week, all content of body composition were similar in all treatments. The proportion of intestinal organ weight was higher in T1 than others during restriction.
