  • The washed fresh ginsengs packed with air, vaccum and nitrogen gas were irradiated at the levels of 1,2 and 3kGy gamma radiation and then stored at $4{\sim}5^{\circ}C$ for 90days to investigate the effects of gamma radiation on microbial inactivation, eelworm disinfestation and physicochemical changes. After a 90 day storage, $2{\sim}3kGy$ irradiated groups showed 20% of weight loss and 10% of rot while non-irradiated group 100% and 20% or more, respectively. Also the irradiated groups showed somewhat lower values of specific gravity, color density and hardness immediately after irradiation, thereafter higher value of them with storage time than those of non-irradiated group. The irradiation increased the yields of ginseng extract and crude saponins but no effects on the proximate composition and TLC and HPLC patterns of saponin. The food-borne microorganisms decreased in viable cell counts by $2{\sim}3$ log cycles with $2{\sim}3kGy$ radiation and the eelworms were completely disinfested with 1 kGy radiation.

  • Purpose: Obesity is often associated with disturbances in the mineral metabolism. The purpose of this study was to investigate the effects of high-fat diet-induced obesity on tissue zinc concentrations and zinc transporter expressions in mice. Methods: C57BL/6J male mice were fed either a control diet (10% energy from fat, control group) or a high-fat diet (45% energy from fat, obese group) for 15 weeks. The zinc concentrations in the serum, stool, and various tissues were measured by inductively coupled plasma (ICP)-atomic emission spectrophotometry or ICP-mass spectrophotometry. The levels of zinc transporter mRNAs in the liver, duodenum, and pancreas were measured by real-time RT-PCR. The levels of serum adipokines, such as leptin and IL-6, were determined. Results: The total body weight, adipose tissue weight, and hepatic TG and cholesterol concentrations were significantly higher in the obese group, as compared to the control group. The obese group had significantly higher levels of serum leptin and pro-inflammatory IL-6 concentrations, and had significantly lower levels of serum alkaline phosphatase activity. The zinc concentrations of the liver, kidney, duodenum, and pancreas were all significantly lower in the obese group than in the control group. On the other hand, the fecal zinc concentrations were significantly higher in the obese group than in the control group. The serum zinc concentrations were not significantly different between the two groups. The ZnT1 mRNA levels of the liver and the pancreas were significantly higher in the obese group, as compared to the control group. Hepatic Zip10 mRNA was also increased in the obese group. Conclusion: Our study findings suggest that obesity increases fecal zinc excretion and lowers the tissue zinc concentrations, which may be associated with alterations in the zinc transporter expressions.

  • This study was implemented in order to investigate the effects of dietary calcium-salt, estrogentreatment, and estrogen/calcium treatment on bone metabolism. Ovariectomized rats were used as animal models. Female Sprague-Dawley rats with a body weight of 250~280g were underwent ovariectomy or sham-operation. The ovariectomized rats were divided into 9 different experimental groups including the saline-treated group, the estrogen-treated group, the high calcium salt-treated group, and the estrogen/calcium treated groups and fed for 6 weeks. Creatinine and hydroxyproline in urine were analyzed. Creatinine, calcitonin, osteocalcin, alkaline phosphatase and parathyroid hormone in plasma were also determined. The results of the experiment are as follows : The ovariectomy caused a significant increase in the level of food intake, food effciency ratio and body weight gain in comparison with sham-operation. The overall food intake, food effciency ratio and body weight gain were significantly decreased by estrogen. The ovariectomized animals developed obesity as a result of increased food intake. In addition, estradiol injections suppressed food intake with a concomitant loss in body weight. The level or urinary hydroxyproline, as an indicator or bone resorntion, was higher in the ovariectomized rats compared to sham-opertion, while these decresed in the estrogen/calcium treated group. Parathyroid hormone and calcitonin in the plasma, that were used as the indicator of calcium homeostasis, parathyroid hormone higher in the ovariectomized rats compared to sham-operation. It was lowered by estrogen and high calcium treated groups; thus, estrogen and estrogen/calcium treated groups were decreased by 32% compared to saline treated group. Osteocalcin and alkaline phosphatase which are indicators of bone formation, were significantly higher in ovariectomized group, while this showed to be decreased in the estrogen and the ostrogenicalcium treated groups. Estrogen and estrogen/calcium in ovariectomized rats resulted in lower bone loss. However, estrogen treated group its gradual reduction showed little effect on bone loss, while the gradual reduction of estrogen had a preventive effect on bone loss when the treatment was combined with calcium intensification.

  • Background: Parathyroid hormone-related protein(PTHrp) was first identified as the cause of hypercalcemia in malignancy. Hypercalcemia can be found in malignancy, especially in the epidermoid carcinoma of the lung, even without extensive metastases to the bones. The application of sensitive assays for PTHrp may help in the early diagnosis of lung cancer, in the monitoring of treatment and in the detection of recurrence. Method: Serum PTHrp was measured by radioimmunoassay detecting the N-terminal 1~34 peptide of human PTHrp(PTHrp 1-34) in 63 histologically confirmed lung cancer patients and 22 healthy controls. Result: Serum PTHrp(mean$\pm$S.E.) was $312{\pm}68.9pg/ml$ in 63 lung cancer patients and $158{\pm}38.2pg/ml$ in 22 controls(p>0.05). PTHrp was $356{\pm}103.9pg/ml$ in 34 epidermoid carcinoma patients, $281{\pm}148.7pg/ml$ in 15 adenocarcinoma patients and $316{\pm}140.8pg/ml$ in 9 small cell carcinoma patients. In epidermoid carcinoma patients, PTHrp was $570{\pm}472.3pg/ml$ in stage II(n=3; p<0.05 vs controls), $166{\pm}22.4pg/ml$ in stage IIIa(n=9), $282{\pm}113.3pg/ml$ in stage IIIb(n=12) and $668{\pm}367.9pg/ml$ in stage IV(n=9; p<0.05 vs controls). PTHrp was significantly increased in 8 epidermoid carcinoma patients with bone metastases($1526{\pm}811.2\;pg/ml$; p<0.0005 vs controls). Hypercalcemia was observed in an epidermoid carcinoma patient whose PTHrp value was 244 pg/ml. Conclusion: The serum PTHrp was increased in advanced epidermoid carcinoma patients even without hypercalcemia. The measurement of PTHrp may be not helpful in the early diagnosis of lung cancer. But the lung cancer should be suspected in the marked elevation of PTHrp. It may be of value in detecting patients of advanced diseases with bone metastases or patients who might develop the malignancy associated hypercalcemia.

  • Purpose of this study is to find out proper means of estimating the urinary mercury excretion in the normal individuals. Whole void volume was collected every 2 hours beginning from 6 o'clock in the morning until 6 o'clock next morning. Mercury excretion in each urine specimen was measured by NIOSH recommended dithizone colorimetric method (Method No.: P & CAM 145). Urinary concentration of mercury was adjusted by two means: specific gravity of 1.024 and a gram of creatinine excretion per liter of urine comparing the data with the unadjusted ones. Mercury excretion in 24-hour urine specimen was calculated by adding the amounts measured with the hourly collected specimens of each individual. Statistical analysis of the urinary mercury excretion revealed the following results: 1. Frequency distribution curve of mercury excreted in urine of hourly specimens was best fitted to power function expressed in the form of $y=ax^b$. Adjustment of the urinary mercury concentration by creatinine excretion was shown to be superior($y=1674x^{-1.52},\;r^2=0.95$) over nonadjustment($y=2702x^{-1.57},\;r^2=0.92$) and adjustment by specific gravity of 1.024($y=4535x^{-1.66},\;r^2=0.93$). 2. Both log-transformed mercury excretion in hourly voided specimens and mercury excretion itself in 24 hour specimens showed the normal distributions. 3. The frequency distribution of mercury adjusting the urinary concentration of mercury by creatinine excretion was best fitted to a theoretical normal distribution with the sample means and standard deviation than those unadjusted or adjusted with specific gravity of 1.024. 4. Average urinary mercury excretions in 24-hour urine specimen in an individual were as follows: a) Unadjusted mercury excretion mean and standard deviation : $$18.6{\pm}13.68{\mu}gHg/l$$. median : $$16.0\;{\mu}gHg/l$$. range : $$0.0-55.10\;{\mu}gHg/l$$. b) Adjusted with specific gravity mean : $$20.7{\pm}11.76\;{\mu}gHg/l{\times}\frac{0.024}{S.G-1.000}$$ median : $$20.7\;{\mu}gHg/l{\times}\frac{0.024}{S.G-1.000}$$ range : $$0.0-52.9\;{\mu}gHg/l{\times}\frac{0.024}{S.G-1.000}$$ c) Adjusted with creatinine excretion mean and standard deviation : $$10.5{\pm}6.98\;{\mu}gHg/g$$ creatinine/l median : $$9.4\;{\mu}gHg/g$$ creatinine/l range : $$0.0-26.7\;{\mu}gHg/g$$ creatinine/l 5. No statistically significant differences were found between means calculated from 24-hour urine specimens and those from hourly specimens transformed into logarithmic values. (P<0.05).

  • To examine the effects of dietary fibers on gastrointestinal physiology, rats were fed with diets containing 10% sodium alginate,10% cellulose, or fiber-free diets for 5 weeks. The results obtained were as follows: The chronic consumption of sodium alginate induced a significant decrease in body weight gain and feeding efficiency, but a significant increase in length and weight of small intestine. Fecal bulk and weight were higher in fiber-fed group than fiber-free group. The chronic consumption of dietary fiber induced a significant increase in fecal output, resulting in tile decrease of apparent digestibility of protein and lipid. Pancreatic protease activity was lower in fiber-fed group than fiber-free group, whereas pancreatic amylase and lipase activities were not affected. Scanning electron microscopy(SEM) and light microscopy(LM) studies showed small intestine microvilli with numerous ridges and convolutions and goblet cells in fiber-fed groups. As a result of this study, it is concluded that the chronic consumption of dietary fiber decreases apparent digestibility of nutrients and induces morphological and biochemical adaptation of digestive organs.

  • 21세기는 과학기술의 비약적인 발전으로 정보통신기술, 환경기술, 나노기술 그리고 생명과학에 의한 바이오기술이 고부가가치 지식산업으로서 국가경쟁력 강회를 위한 국가전략 핵심산업으로 대두되고 있습니다. 특히 바이오기술의 응용산업인 건강기능식품은 국민의 질병예방과 건강증진을 통한 삶의 질 향상에 이바지하고, 21세기 미래 고부가가치산업으로 발전할 것으로 기대하고 있습니다. 이러한 시기에 국민보건과 건강기능식품산업의 발전을 위한 건강기능식품에 관한 법률(건강기능식품법) 이 의원입법으로 국회에 상정되어 1년 이상의 검토를 거쳐 지난 7월 31일에 국회 본회의를 통과하였습니다. 그후 8월 26일자로 이 법을 정부에서 공포하였으며 내년 8월 26일부터는 발효할 예정입니다. 그러나, 건강기능식품법의 제정은 건강기능식품관련 제도의 완성이 아니라 시작입니다. 즉, 건강기능식품법의 기초는 마련하였지만, 그 하위법인 시행령, 시행규칙, 고시등이 제대로 된 모습을 갖추어야 비로소 국민이 만족하고, 산학연의 동반 발전을 이룰 수 있는 이 분야의 산업발전을 기할 수 있습니다. 그리고, 건강기능식품담당 정부부처인 식품의약품안전청은 현실적으로 그 하위법을 금년 말(2002년)이나 내년 초(2003년)에 준비한 후 입법 예고하여야하는 시간적 제약을 안고 있습니다. 이러한 연유로 단기간 내에 하위법을 준비하다 보면 자칫 애초에 정부와 산학연이 바라던 바와는 다른 엉뚱한결과를 초래할 우려가 있는 만큼, 법 제도의 명확한 방향설정이 매우 중요합니다. 그래서, 한국식품과학회 건강기능식품분과위원회는 이 문제의 중요성을 깊이 인식하고 산학연 전문가그룹(식품과학자, 영양과학자, 학계, 연구계, 기업계: 16인)을 구성하였습니다. 전문가그룹은 지난 7 - 8월, 2달 동안에 수 차례 회의를 통하여, 건강기능식품법 하위법 준비 중 핵심사항은 건강기능식품의 기능성 표시와 평가 라는 점에 착안하고, 이에 대하여 중점적으로 검토하였습니다. 그 이외에도 섭취량 설정 , 심사자료의 인증요건 , 기능성분의 표시 등에 대하여도 부수적으로 검토하였습니다. 그 결과, 동물실험을 이용한 기능성평가 방향 (이미 본지의 전호에서 게재한 바 있어생략)을 제외한 주요사항을 다음의 별도 기사로 각각 소개합니다. 또한, 이 내용은 지난 9월 13일, COEX에서 제1회 건강기능식품 전시회 및 학술세미나 행사의 일환으로서 개최된 학술세미나에서 발표하고 토론회를 거쳤습니다. 또한, 지난 10월 26일, 무주리조트에서 식품과학회 추계학술대회 행사의 일환으로 개최된 건강기능식품분과위원회의 토론회에서도 좋은 의견을 교환한 바 있습니다. 두 차례의 토론회를 통하여 건강기능식품분과위원회가 제안한 초안이 대체적으로 매우 바람직한 것으로 평가받았으며 많은 동의를 얻었습니다. 이어서 토론회의 내용을 반영한 식품과학회의 안을 최종적으로 준비하고 이를 11월초에 식품의약품안전청에게 정책 건의하였습니다. 다음의 별도기사에 덧붙여서, 토론회를 통하여 수정(또는 강조)하고자 하는 부분은 아래와 같습니다. 1) 동물실험 등에서 흡수, 대사 등으로 표기한 서술 용어는 흡수, 분포, 대사, 배설 로 대체합니다. 2) 기능성 평가방법의 표준화와 관련하여 분과위원회에서 제시한 안은 평가방법은 심의위원회가 사안에 따라 기능성 평가시에 그 평가방법의 적합성을 검토함이 바람직하다 라고 하였습니다. 그러나, 이를 부분적으로는 평가방법을 표준화할 필요가있다 로 수정하고자 합니다. 즉, 평가방법이 전혀 제시되지 않으면 막막함으로, 기본적인 방법이면서 여러사람들이 참고로 할만한 방법에 대하여는 표준화를 병행함이 더욱 좋겠다고 생각합니다. 또한, 표준방법으로 제시된 것만이 유일한 방법은 아니므로 다른 방법으로 평가하는 것도 가능함으로 제시합니다. 3) (가칭)건강기능식품 인체시험 관리지침과 관련하여 이는 식약청장이 정할 사안이지만, 그것은 국내 의약품 임상시험 관리지침 과는 뚜렷이 차별화되는 것으로 실제로는 의사의 도움없이도 인체시험을 시행할 수 있음을 명확히 할 필요가 있습니다.

  • Most of mothers place their babies in either supine or prone position without change of position. Studies comparing supine and prone position of the newborn infants -have already been performed with the result that the prone position is relatively better than the supine position. However, one kind of position recommended to the mothers is not sufficient for the good rearing practice of children, because the same position placed for period long of time may bring out physical, mental tension and fatigue, and deformities of the skull and the thorax. For this reason nurses have to find out other position which has identical or more advantages than prone position so as to perform the position change for the babies. Main purpose of this study is to identify the differences of vital signs, the number of urination, defecation, diaper rash, crying and amount of feeding of the newborn infants with prone position or lateral position during the first three days of life. Sixty two newborn infants who were delivered at Seoul National University Hospital during the period from July 1 to September 5, 1974 were chosen as subjects for this study. The criteria for the choice of subjects were the babies born with vaginal delivery; body weight 2.5kg or over at birth; Apgar score Seven or over; and gestation period between thirty-eight months ana forty- two months. Of these subjects, by random sampling, thirty-one newborn infants were placed in the prone position and the other thirty-one in the lateral position. The results of this study reviewed in a statistical analysis of the t-test to obtain the following findings : 1. The heart rates of babies in the prone position were the mean heart rates of 135.03 and those in the lateral position 135.98 without any statistically significant difference. 2. There was no significant difference of respiration rate between two groups : a group in the prone position showed the mean respiration rates of 45,57 and the other in the lateral position 46.49. 3. There was no significant difference of body temperature between two groups: the mean body temperature of a group placed in the prone position was 98$^{\circ}$18'F(36$^{\circ}$77'C) and that of the other group 98$^{\circ}$20'F(36$^{\circ}$78'C). 4. One baby showed diaper rash only in a group of infants in the prone position. 5. The number of crying of the babies in the prone position were 23.70 and those in the lateral position 30.00 with a statistical difference at 5 percent level. 6, There was no difference of frequency of urination between two groups: the mean frequency of a group placed in tile prone position was 5.44 and that of the other group 5.06, 7. There was no significant difference of frequency of defecation between two groups : the mean frequency of a group placed in the prone position was 4.20 and that of tile other group 4.21, 8. There was no significant difference of feeding amount between two groups : the average amount of a group in the prone position showed 325.03 and that of the other group in the lateral position 291.51. All the above results mean that we may substitute tile lateral position for the Prone position or utilize both position for tile rearing practice of the babies.
