In an attempt to figure out the relationship between zinc status and taste acuity of old and young women, dietary zinc intake, urinary zinc excretion, and taste acuity were determined for 118 women. Zinc intake was measured by 2-day food records and food frequency method. Urinary zinc excretion was measured from urine samples collected for twenty four hours. Body fat, lean body mass (LBM), and total body water were measured by bio-impedence. Average dietary zinc intake by food record was 4.15+/-1.33mg (=35% if Korean RDA) for the old women and 5.41+/-2.76mg (=25% of RDA) for young women. When zinc intake was measured by a frequency method, the average intakes of the old and young women were 3.5+/-1.7mg 4.5+/-1.9mg, respectively. It appears that dietary zinc intake of young women was significantly higher than that of the old women. Average urinary zinc excretion of the subjects was 0.27+/-0.16mg in the elderly and 0.24+/-0.13mg in young women, which indicated a marginal zinc status. However, zinc status was not significantly different between old and young women. Correlation analysis indicated that zinc intake and urinary zinc excretion were positively related to BMI and LBM in young women. The old women (m=49) showed significantly higher taste detection thresholds than young subjects (n=47) for both sweet and salty tastes. Recognition thresholds for sodium chloride and sucrose were not significantly different between old and young women. The lower the taste thresholds for salty taste, the higher the average dietary zinc intake. However, taste perception concentration was not related to the urinary zinc excretion level.

The purpose of this study was to investigate the dietary behavior of people with type 2 diabetes mellitus and to improve their quality of life through medical nutrition therapy. The subjects were 38 persons with type 2 diabetes mellitus visiting a public health center to participate in a dietary education program from Jun, 2003 to Nov. 2003 in Daegu, Korea. The interviews were tape-recorded and analyzed attitude, knowledge, and awareness of patients by focus group interview. Most of the patients were mainly dependent on drug therapy and had little experience of diet education. Barriers to dietary practice adherences were limitations in food selection, lack of will and feel of burden. Barriers to follow guidelines were lack of self-control, confliction with food habits of their family, accessibility, economical problems, fear for the change after dietary practice, food difficulties in meal distribution and difficulties for eating out. After 4 weeks of intensive nutrition education, fasting blood sugar levels were decreased and postprandial and waist circumference were significantly decreased in all patients and 26.9% of patients were under decreased oral hypoglycemic agent dosage due to improved blood sugar level. dietary knowledge of subjects were greatly improved in such items as dietary intake, saturated fat, HbA1C, ideal body weight, and waist circumference.

Literature suggests that iron deficiency anemia is prevalent among pregnant women all over the world. This study was designed to evaluate the iron status of pregnant women during the fist five months, with the intention of determining ways to reduce the prevalence of iron deficiency anemia among pregnant women in Korea. We collected dietary information and measured the biochemical status of iron in 171 pregnant women over 16 weeks of gestation (= 16.7 +/- 2.34 week). Dietary intakes for 3 days were collected using the 24 hour recall and food record methods. The daily Fe intake was measured using the food frequency method. The Body Mass Index (BMI), calculated by using the pre-pregnancy weight and height, indicated that 31.3% of subjects were under-weight. We divided the subjects into normal and anemic group by using the serum ferritin levels. It appeared that the mean dietary intake of iron was 52.3% of the recommended level for pregnant women. The dietary quality evaluation showed that pregnant women ate only 58% of the recommended amount in the food groups of meat, fish, eggs, beans and milk and dairy products. The hematological indices showed that the mean Hemoglobin (Hb) was 11.9 g/dl, Hematocrit (Hct) was 35.1%, ferritin was 23.9 ng/ml, and transferrin was 297.3 microgram/dl. The dietary intake of iron was significantly lower and the vitamin C intake was significantly higher in the anemic group. The pre-pregnancy BMI was significantly lower in the anemic group. Variables affecting iron intake were the Fe intake frequency index and the food group score. The Fe index showed significantly positive correlation with the pre-pregnancy food intake and the food group score. Hb showed a significantly positive correlation with the prepregnancy food intake. We concluded that strategies to improve iron status be implemented in the pre-pregnant stage so as to reduce the prevalence of iron deficiency and that we should stress on the importance of an adequate diet as well as the maintenance of a heathy weight.

OBJECTIVE: The present study was conducted to evaluate the viability of germ cells form the adult and fetal ovarian tissues after vitrification followed by xenografting. METHOD: The human adult ovarian tissues were obtained from 33 years old patients, and the fetal ovarian tissues were obtained from 22 weeks and 25 weeks in gestation. ovarian tissues were cryopreserved by vitrification with 5.5 M ethylene glycol (EG 5.5) and 1.0 M sucrose as cryoprotectants. Adult and fetal ovarian tissues were pre-equilivrated with EG 5.5 at room temperature for 10 and 5 minutes, respectively and plunged into liquid nitrogen immediately. Frozen-thawed tissues were xenografted into NOD-SCID mice to evaluated the viability and capacity for further growth of the primordial follicles. Grafts were recovered from the recipients 4 weeks after transplantation and histological analysis was accomplished. RESULT AND CONCLUSION: Grafts recovered 4 weeks after transplantation contained less number of oocytes and primordial follicles compared to that of the fresh tissues. Survived follicles were mainly primordial and intermediary with larger diameter and more granulosa cells. It is confirmed that 1) the ovarian tissues were healthy and the germ cells were survived after vitrification, and 2) the survived fetal primordial follicles after vitrification resumed the growth in the xenofrafts.

Primary signet ring cell carcinoma of the prostate is extremely rare and about 18 cases have been reported in the literature. We report two cases of primary signet ring cell carcinoma of the prostate, arising in 79-year-old and 65-year-old men. Both cases were the poorly differentiated adenocarcinoma of the prostate with many signet ring cells. Signet ring cells were positive for prostatic specific antigen and prostatic acid phosphatase but negative for neutral and acid mucins. In summary, the signet ring cell carcinoma of the prostate is a rare variant of poorly differentiated adenocarcinoma of the prostate. The orgin of the prostate should be considered in cases of metastatic signet ring cell carcinoma, particularly when the signet ring cells are negative for neutral and acid mucins. Prostatic specific antigen and prostatic acid phosphatase should also be performed to confirm the primary signet ring cell carcinoma of the prostate.

Iron deficiency anemia is a worldwide public health problem relevant to unsound nutritional practice. While the prevalence of iron deficiency anemia is very common among pregnant women, appropriate nutritional service programs to improve the iron status are lacking in Korea. In an attempt to develop a nutritional screening tool to separate the high-risk subjects of iron deficiency, we carried out a nutritional survey for 115 Korean pregnant women whose gestational age ranged from 13 to 24 weeks. Each subject was interviewed with questionnaires for general characteristics and dietary habits. Food intake was measured by 24-hour recap method and 2 day record. Fasting blood was drawn for measuring hemoglobin and serum ferritin. It appeared that half of the pregnant women belonged to the anemia group and had insufficient dietary habits to provide adequate amounts of dietary iron. The first gravida and the working women had better hematological iron indicators than the second or more gravida and the housewives. It also appeared that women who had bigger family size and lower BMI in pre-pregnancy had poorer iron status. Among the food consumption habits, fruit dependent dietary habit was related to poor iron status. Sufficiently consumed green leafy vegetable and appropriate amount of food before morning sickness were positive factors of iron stares. Our results indicated that parity, BMI, current job, family size, food habits including consumption of fruits, green & yellow vegetables, and food habits before the onset of morning sickness are significant factors to contribute the Fe deficiency anemia during pregnancy.
