난소홀몬이 가토 Insulin 131I 대사에 미치는 영향
박제우(JW Park) 대한산부인과학회 1966 Obstetrics & Gynecology Science Vol.9 No.11
Twenty one of ovariectomized rabbits were divided into 3 groups: the first group for control, the second group for estrogen stimulated group and the third group for progesterone stimulated group. In each group, after a single injection of insulin-131I(30-100μc.), blood samples were withdrawn at the interval of 10 minutes for 50 minutes and plasma disappearance of injected insulin-131I with time were observe. On the other hand, 50 minutes after injection of insulin-131I of plasma-time curves, turnover rates of insulin and half time, which is the time required to turnover a half insulin pool, were valulated from each group. On the other hand, 50 minutes after injection of insulin-131I, animals were sacrificed and various tissues were excised. Weighed tissues were mixed with 10% trichloroacetic acid(TCA) in motor and divided into 2 fractions by centrifugation. Each fraction of tissue homogenate was counted for radioactivity by means of well type scintillation counter. Insulin-131I spaces in various tissues were calculated by obtaining the ratio of radioactivities of TCA precipitable fractions of tissues to that of plasma, while 131I compound space, which is the distribution spaces of degradated products of injected insulin-131I, were calculated with ratios of radioactivities of TCA soluble fraction of tissues to that of plasma. Alterations in turnover rates of insulin by ovarian hormons were analyzed by connection the distribution spaces of insulin-131I in various tissues of each group. 1) After a single injection of insulin-131I, plasma disappearance of insulin-131I was decreased exponentially with time showing straight line on the semilogarithmic paper. Therefore, turnover rate can be calculated by obtaining the slope of radioactivities of plasma insulin-131I vs. time curve and also half time(t½)of insulin turnover by the first order kinetic equation. The turnover rate of insulin was mean of 1.90%/min. in the first group, 2.53%/min. in the secon group and 2.18%/min. in the third group. These data showed that turnover rates of insulin were increased by stimulation with ovarian gormones. 2) Insulin-131I space in the kidney tisseue showed most highest value and averaged about 700%, which value represents about 7 times of concentration of plasma insulin-131I in the kidney. In the other tissues insulin-131I space were decreased by in order of spleen, skin, heart, liver, small intestine, uterus, adipose, skeletal muscle and brain tissues. However, there were little differences in insulin-131I space between control and ovarian hormone stimulated groups. 3) In order to observe the degradation of insulin in various tissues, 131I compound spaces were determined by ratio between radioactivities of TCA soluble fractions of tissues and plasma. 131I compound spaces in kidney, liver, spleen and adipose tissues showed more than 100%, in which tissues radioactivities of TCA soluble fractions were more concentrated than in the plasma. It seems that these tissues would be principal sites of insulin degradation. In the other tissues, 131I compound spaces were decreased by in order of small intestine, heart, skin, uterus, skeletal muscle and brain tissues. However, there are remarkable increase in the 131I compound spaces of kidney and liver which have insulinase system by stimulation of ovarian hormones and also degradation of
신품종딸기의 동남아시장 수출확대방안에 관한 연구- 태국시장을 중심으로

이 연구는 태국 딸기시장에서 한국 딸기의 전략적 포지션 확인 및 신품종 딸기 킹스베리와 금실에 대한 소비자조사를 기초로 신품종 딸기의 선호도 및 품질만족도에 관한 관계를 기술하고 신품종 딸기의 구매의사에 영향을 미치는 예측요인을 식별함으로써 태국 딸기시장 수입시장점유율을 어떻게 확대해 나갈 것인지 모색하는데 있다. 미국무역위원회(ITC)의 무역통계자료를 활용하여 태국 시장에서의 전략적 포지션을 확인하였으며, 설문조사는 방콕 시내에 딸기 소비자 412명을 대상으로 신품종 딸기 킹스베리와 금실에 대해 시식테스트를 실시하고 품질만족도 등을 조사하였다. 수집된 자료는 t-검증 및 로지스틱회귀분석을 실시하였다. 분석결과, 한국 딸기는 태국시장에서 호주 뉴질랜드 일본을 제치고 수입시장점유율 1위를 조사 되었다. 품질 만족도는 상대적으로 킹스베리 보다 금실이 더 우수한 것으로 평가됐다. 또 딸기 선호도는 킹스베리 보다 금실을 더 선호하는 것으로 나타났다. 딸기구매의향에 영향을 미치는 예측요인은 킹스베리의 경우 당도, 경도 및 향미를 개선하는 경우 구매가능성이 높아지는 것으로 나타났다. 반면, 금실의 경우 향미, 향기 및 과즙을 개선하면 구매가능성이 높아질 가능성이 있으나 통계적으로 유의하지는 않았다. 분석결과를 바탕으로 딸기 수출확대를 위한 마케팅 4P-Mix전략을 제시한다. 제품믹스전략은 현지 소비자의 다양한 니즈에 부응하기 위해서는 단맛 신맛 경도 등을 조합한 다양한 맛의 수출용딸기 품종 구색을 갖출 필요가 있다. 또 호주 뉴질랜드의 남반구 딸기의 공급 시기 및 종기 확장에 대응하여 사계절 딸기생산 및 공급시스템을 갖출 필요가 있다. 가격믹스전략은 다양한 품종과 가격대를 가진 딸기 패키지를 개발할 필요가 있다. 프로모션 믹스전략으로는 한국 딸기와 일본딸기의 혼동에 따른 딸기선호도 왜곡에 대응하기 위하여 공동브랜드와 로고를 사용할 필요가 있다. 추가적인 시장점유율 확대를 위해서는 대형할인점 하이퍼마켓 및 백화점 이외에 편의점 과일전문점 또는 재래시장까지 유통채널을 확장하여 고객접점을 확대할 필요가 있다. 또 차별적인 제품 포지셔닝 개발과 커뮤니케이션 전략을 포함하는 마케팅 전략수립이 요구된다. 제한된 표본사용으로 인해 과도한 일반화에는 한계가 있으며, 향후 더 엄격한 기호도 평가와 표본추출을 통해 추가적인 확인이 필요하다.

In recent years the analysis of the protein components in the cervical mucus has drawn more attention with respect to the possible occurrence of a biologic infertility cause by an immune reaction between sperm antigen and cervical mucus antibodies, and antimicrobial prophyractic immunity. Immunoelectrophoretic studies on cervical mucus have already been undertaken by several workers, but there is not complete agreement as regards to proteins in cervical scretions obtained from nonpregnant women as yet probable due to differences in techniques used. It was the purpose of this study to investigate in single, undiluted specimens the appearance of serum proteins in cervical mucus of Korean women during different stages of the menstrual cycle. Summary 1) A complete study of the proteins of normal cervical mucus has been made by immunoelectrophoresis in cases of Korean women. 2) Albumin, transferrin, and gamma globulin(IgG) were always found, and in the half of the cases alpha-2 globulin and IgA were present. 3) No significant differences in protein component of cervical mucus were found in regard to menstrual cycle. 4) The possible role of cervical mucus(especially, IgG and IgA) in the production of biological infertility and antimicrobial prophylactic immunity was discrssed together with the limits and merits of the immuno elctrophoretic method in the study of the cervical mucus.

The myoma is the most common tumor of the uterus. It is estimated that about 20%of all women over 35 years of age have uterine myomas, although frequently without symptoms. But it seems to be rare to experience a intraligamentary huge leiomyoma. Recently we have experienced a case of intraligamentary huge leiomyoma with its weight of 3,300gm in a 41 year-old multiparous woman and a brief review of the case and its literatures are presented.
