Densitometric measurement of total body fat and total body water in male adults.

Densitometry was performed on 54 male medical studentsCaverage age: 21.4 years). In another group of 10 male subjects Cage: 34.5 yr.) measurements were made on the total body water by means of antipyrine dilution and densitometry in the same subjects. Values of body fat and body water calcu' lated from the body density and total body water coincided each other with considerable accuracy. CTable 2) The following figures for the standard reference body of male Korean were obtained: average age of 21.4 years. 167.5 em in height and 57.2 kg in weight. body density 1.067. total body fat 12.8% body weight, total body water 63.8% body weight

The moderating effect of trust on the relationship between air force pilot’s organizational conflict and turnover intention

본 연구는 공군 조종사를 대상으로 개인적 갈등, 개인 간 갈등, 개인과 집단 간 갈등이 이직의도에 미치는 영향을 살펴보고, 갈등유형과 이직의도 간의 관계를 조절할 수 있는 변수로 신뢰를 설정하여 조직신뢰, 상사신뢰, 동료신뢰의 조절역할을 살펴보는데 그 목적이 있다. 이를 위해 공군 조종사 333명을 대상으로 다중회귀분석과 위계적 회귀분석을 실시한 결과, 조직갈등이 이직의도에 유의미한 정적인 영향을 미치고, 개인적 갈등과 이직의도의 관계에서 조직신뢰의 조절효과(정적 관계를 약화)가 있는 것으로 나타났다. 개인적 갈등, 개인간 갈등, 개인과 집단 간 갈등과 이직의도의 관계에서는 리더신뢰의 조절효과는 없었지만, 동료신뢰의 조절효과는 확인할 수 있었다. 반면에, 개인 간 갈등과 이직의도의 관계에서는 동료신뢰가 정적 관계를 강화시켜주는 것으로 나타났다. 끝으로 분석결과를 토대로 본 연구의 시사점과 인적자원개발 측면에서 필요한 조직차원의 실행방안을 제시하였다.The purpose of this study is to examine the effects of intrapersonal, interpersonal and individual-group conflict on turnover intention and the moderating effects of organization, supervisor and colleague trust. We surveyed 333 air force pilots and employed multiple linear regression analysis and hierarchial regression analysis. The findings are as follows: organizational conflict has a significant positive effect on turnover intention; trust has moderating effect on the relationship between intrapersonal conflict and turnover intention; colleague trust has a moderating effect on organizational conflict. In particular, this study shows that colleague trust has influence on the positive relationship between intrapersonal conflict and turnover intention. Based on these findings, we suggested the implications of this study and the necessary practical measures of HRD on the organizational level

Effect of Perphenazine Hydrochloride on the Prolactin Cells of Rat Pituitary Glands

The effect of perphenazine hydrochloride on the prolactin cells of rat pituitary glands and mammary glands were studied. Virgin rats which had been primed with 0.2ml of estradiol for 10 days or not primed were injected with perphenazine intraperitoneally for 1 day or repeatedly every 5 days for 15 days. Sections of pituitary glands from them were carried out to stain the prolactin cells immunohistochemically using the specific anti-prolactin and antiRGG labeled with peroxidase. Sections of mammary glands were stained with hematoxylin and eosin . Cell counts were made from 10 representative section of corresponding levels of each gland. and the following results were obtained. Even in lower dose of perphenazine. 3mg/day for 1 day. releasing effect of prolactin granules were apparent. Perphenazine produced a significant decrease in prolactin cell counts and in the intensities of staining reaction which were recovered 20 days after injection to almost same levels of control group. The higher doses of perphenazine also developed the proliferation of lobulo-alveolar structure of the mammary glands. In estradiol-primed rats either lower or higher doses of perphenazine could revealed the same findings in both of pituitary and mammary glands. There were significant increase in adrenal weight and decrease in ovarian weight

An Experimental Study on he Blood Picture and the Lymphocyte Transformation in Autoimmune Thyroiditis.

Recent interests h. autoimmune diseases with investigations on its ifIh…mological character elucidated the nature of variou.; human disorders such as Sj6rgens disease, S. L. c. pernicious anemia. rheum atoid arthritis, chronic thyroiditis. especially of Hashirr.oto s lyphocytic ty /,c and other diseases, yet the pathogenesis is not fu1Jy clarified The authors attempted an experimental study for further elucidation of the pathogenesis of autoimmune thyroiditis. The lymphocytes from rabbits sensitized with homologous thyroid extract and/or adjuvant was cultured in the presence of homologous thyroid and the peripheral blood pictures during the sensiti zation antigen and non-specific stimulant PHA. The rates of lymphocyte transformation in 72• hour cultures were analyzed. The results are summerized as follows: I. Changes of hemoglobin values and peripheral leucocytosis of each experimental group were slight, however the leucocytosis and relative lymphocytopenia were observed in the group sensitized with a mixture of homologous thyroid extract and Freunds adjuvant 2· The transformation of peripheral blood lymphocytes of normal rabbits in the presence of homol ogous thyroid extract was 、ery few and almost negl igible 3. Lymphocytes of rabbits sensitized with thyroid ext;:-act showed evidently higher transformation rate than that of unsensitize:l normal rabbits in the present:e of homologous thyroid extract, he'; e'.'er these lymphocytes showed almost same degree of transformation rates in the presence of PHA as in unsensitized normal groups of rabbits. 4. Transformation rates of lymphocytes of either group sensitized with Freunds adjuvant or homologous thyroid extract showed similar results when cultureJ with either the thyroid extract or PHA in vitro 5. Lymphocytes from the rabbits sensitized with a mixture of homologous thyroid extract and Freund S adjuvant gave higher transformation rates than that of any other groups. 6. Lymphocytes sensitized with homologous thyroid extract showed variable rates of transformation according to the indivisuality of the rabbits. It is thought that these variabilities are due probably to the degree of sensitization or susceptibility of indi visual rabbit to the PHA or the antigens. It is summerized that the rate of blastogenesis of rabbit lymphocytes stimulated by thyroid extract and cultured with thyroid extract or PHA is similar to that of adjuvant stimulated, while that of thyroid extract with adjuvant is remarkably higher than 'the above two experimental groups. This results suggest that the specific and non-specific stimulation of T -lymphocytes may be closely related to the pathogenesis of autoimmune thyroiditis
