  • Vitamin C is an essential nutrient involved in many functions. Humans are unable to synthesize vitamin C do novo, because they lack the last enzyme in the biosynthetic pathway. Previous Recommended Dietary Allowances (RDAs) for vitamin C were based on prevention of deficiency with a margin of safety. However preventing deficiency may not be equivalent to ideal nutrient intake. Recommendation should be based on vitamin function in relation to concentration. For this goal, data set of the relationship between wide-range of vitamin C dose and resulting concentrations in plasma and tissues and characterization of functional outcomes in relation to these concentrations should be acquired. This article reviews the current knowledge in these areas and suggest how this knowledge may contribute toward establishing dietary guideline for ideal vitamin C intake.

  • The aim of this trial was to study the response of laboratory animals including omnivores (rats) and herbivores (rabbits, guinea pigs and hamsters) to the same level of dietary fiber on their digestive enzymes and hindgut fermentation. Ten weanling animals of each of four species, rabbits, guinea-pigs, rats and Syrian hamster, were fed a basal diet of 18% crude protein and 10% crude fiber for six weeks. The digesta and tissue of each intestinal segment were collected to measure the activity of digestive enzymes. Rabbits contained the highest secreted pepsin activity in the stomach, whereas rats contained the highest protease and ${\alpha}-amylase$ activity in the small intestine, and lower fibrous hydrolases in the hindgut than rabbits, guinea pigs and hamsters. The total VFA productions in the caecum and colon were highest in rats, followed by hamsters and rabbits, while the guinea pigs contained the lowest VFA and a different pattern of VFA molar ratio from the other laboratory animals. The degree of hindgut fermentation in these laboratory animals was in reverse to the trend for their fiber digestion.

  • The purpose of this study was to define the content of requisite human structure and function knowledge needed for clinical knowledge of nursing practice. Subjects of human structure and function were divided into 10 units, and each unit was further divided into 21 subunits, resulting in a total of 90 items. Contents of knowledge of human structure and function were constructed from syllabus of basic nursing subjects in 4 college of nursing, and textbooks published by nurse scholars prepared with basic nursing sciences. The degree of need of 90 items was measured with a 4 point scale. The subjects of this study were college graduated 136 nurses from seven university hospitals in Seoul and three university hospitals located in Chonnam Province, Kyungbook Province, and Inchon. They have been working at internal medicine ward, surgical ward, intensive care unit, obstetrics and gynecology ward, pediatrics ward, opthalmology ward, ear, nose, and throat ward, emergency room, rehabilitation ward, cancer ward, hospice ward, and their working period was mostly under 5 years. The results were as follows: 1. The highest scored items of human structure and function knowledge necessary for nursing practice were electrolyte balance, blood clotting mechanism and anticoagulation mechanism, hematopoietic function, body fluid balance, function of plasma, and anatomical terminology in the order of importance. The lowest scored items of human structure and function knowledge necessary for nursing practice was sexual factors of genetic mutation. 2. The highest order of need according to unit was membrane transport in the living unit, anatomical terminology in movement and exercise unit, mechanism of hormone function in regulation and integration unit, component and function of blood in oxygenation function unit, structure and function of digestive system in digestive and energy metabolism unit, temperature regulation in temperature regulation unit electrolyte balance in body fluid and electrolyte unit, concept of immunity in body resistance unit, and genetics terminology in genetics unit. The highest order of importance according to subunit was membrane transportation in cell subunit, classification of tissues in tissue unit, function of skin and skin in skin subunit, anatomical derivatives of the skeleton subunit, classification of joints in joint subunit, an effect of exercise on muscles in muscle subunit, function of brain in nervous system subunit, special sense in sensory subunit mechanism of hormone function in endocrine subunit, structure and function of female reproductive system in reproductive system unit, structure and function of blood in blood unit, structure of heart, electrical and mechanical function in cardiovascular system unit, structure of respiratory system in respiratory system subunit, structure and function of digestive system in digestive system subunit, hormonal regulation of metabolism in nutrition and metabolism subunit, function of kidney in urologic system subunit, electolyte balance in body fluid, electolyte and acid-base balance subunit. 3. The common content of human structure and function knowledge need for all clinical areas in nursing was structure and function of blood, hematopoietic function, function of plasm, coagulation mechanism and anticoagulation mechanism, body fluid, electrolyte balance, and acid-base balance. However, the degree of need of each human structure and function knowledge was different depending on clinical areas. 4. Significant differences in human structure and function knowledge necessary for nursing practice such as skin and derivatives of the skin, growth and development of bone, classification of joint, classification of muscle, structure of muscle, function of muscle, function of spinal cord, peripheral nerve, structure and function of pancrease, component and function of blood, function of plasma, structure and function of blood, hemodynamics, respiratory dynamics, gas transport, regulation of respiration, chemical digestion of foods, absorption of foods, characteristics of nutrients, metabolism and hormonal regulation, body energy balance were demonstrated according to the duration of work. 5. Significant differences in human structure and function knowledge necessary for nursing practice such as classification of tissue, classification of muscles, function of muscles, muscle metabolism, classification of skeletal muscles, classification of nervous system, neurotransmitters, mechanism of hormone function, pituitary and pituitary hormone, structure and function of male reproductive organ, structure and function of female reproductive organ, component and function of blood, function of plasma, coagulation mechanism and anticoagulation mechanism, gas exchange, gas transport, regulation of respiration, characteristics of nutrients, energy balance, function of kidney, concept of immunity, classification and function of immunity were shown according to the work area.

  • The hypothalamic-pituitary-adrenal (HPA) axis is the primary endocrine system to respond to stress. The HPA axis may be affected by increased level of corticotrophin-releasing factors under chronic stress and by chronic administration of monosodium glutamate (MSG). The purpose of this study was to investigate whether chronic MSG administration aggravates chronic variable stress (CVS)-induced behavioral and hormonal changes. Twenty-four adult male Sprague-Dawley rats, weighing 200~220 g, were divided into 4 groups as follows: water administration (CON), MSG (3 g/kg) administration (MSG), CVS, and CVS with MSG (3 g/kg) administration (CVS+MSG). In addition, for the purpose of comparing the effect on plasma corticosterone levels between chronic stress and daily care or acute stress, 2 groups were added at the end of the experiment; the 2 new groups were as follows: naive mice (n=7) and mice exposed to restraint stress for 2 h just before decapitation (A-Str, n=7). In an open field test performed after the experiment, the CVS+MSG group significant decrease in activity. The increase in relative adrenal weights in the CVS and CVS+MSG group was significantly greater than those in the CON and/or MSG groups. In spite of the increase in the relative adrenal weight, there was a significant decrease in the plasma corticosterone levels in the CVS+MSG group as compared to all other groups, except the naive group. These results suggest that impaired HPA axis function as well as the decrease in the behavioral activity in adult rats can be induced by chronic MSG administration under CVS rather than CVS alone.

  • Objectives : The purpose of this study is to compare atopic dermatitis and food allergy of Korean Medicine with those of western medicine. Methods : We examined the relationship between atopic dermatitis and food allergy mainly in digestive system abnormalities through literature review. Results : Food allergy is classified into categories such as diarrhea, abdominal pain and cough caused by retention of undigested food(食積) and pimples(癮疹) in Korean medicine. The side effects caused by specific immune reactions occur repeatedly due to exposure to specific food allergen or retention of undigested food. Atopic dermatitis and food allergy are often coexisting and deeply related. Digestive system abnormalities can result not only in indigestion but also in immune function abnormalities. Food allergies are known to cause atopic dermatitis and the influx of food antigens exacerbates atopic dermatitis. This corresponds to atopic dermatitis due to abnormal digestive system(脾胃) accompanied by fever(熱), wind(風), and weakness(虛) with focusing on dampness(濕). A typical example of the relationship between atopic dermatitis and food allergy in Korean medicine is Tae-yeul (胎熱). Tae-yeul refers to atopic dermatitis caused by a sensitization to reaction to the dietary antigens of the mother through the placenta during the fetal life with a unusual genetic disposition. Conclusions : We compared korean medicine with western medicine for atopic dermatitis and food allergy. Atopic dermatitis caused by abnormal immune function due to ingestion of food antigen corresponds to dermatitis due to retention of undigested food(食積), digestive system(脾胃臟) problems in korean medicine.

  • The history of liver surgery is a tale of progressive resolution of issues presenting one after another from ancient times to the present days when dealing with liver ailments. The perfect knowledge of human liver anatomy and physiology and the development of a proper liver resective surgery require time and huge efforts and, mostly, the study and research of giants of their own times, whose names are forever associated with anatomical landmarks, thorough descriptions, and surgical approaches. The control of parenchymal bleeding after trauma and during resection is the second issue that surgeons have to resolve. A good knowledge of intra and extrahepatic vascular anatomy is a necessary condition to develop techniques of vascular control, paving the way to liver transplantation. Last but not least, the issue of residual liver function after resection requires advanced techniques of volume redistribution through redirection of blood inflow. These are the same problems any young surgeon would face when approaching liver surgery for the first time. Therefore, obtaining a wide picture of historical evolution of liver surgery could be a great starting point to serve as an example and a guide.

  • Sasang Digestive Function Inventory (SDFI) and Sasang Personality Questionnaire (SPQ) were developed on the basis of clinical experiences of Korean medicine hospital and previous studies have used these for analyzing Sasang constitutional characteristics mainly in hospital level. The purpose of this study is to analyze Sasang constitutional characteristics using SDFI and SPQ in clinical level. The SPQ, SDFI, height and weight were measured with 79 patients over 18-years-old from Jan. 2015 to Apr. 2016 in the clinic, Daegu, Korea that specializes in tinnitus and performs Sasang constitution diagnosis. We used ANOVA in analyzing the differences of the scores of SPQ, SDFI, BMI and PI in each Sasang types (Tae-Yang, So-Yang, Tae-Eum), and Bonferroni test or Dunnett's T3 for post verification. The SDFI-T(F=3.215) and SDFI-D(F=4.347) scores were significantly different(p<0.05) and SPQ score was not different in each Sasang types(p>0.05). And Weight(F=4.294), BMI(F=12.386) and PI(F=14.490) were significantly different in each Sasang types(p<0.001). We found that SDFI(SDFI-D) and BMI PI can explain the Sasang constitutional characteristics, that is equivalent to previous studies and might be used for clinical index in making objective questionnaire for Sasnag constitutional diagnosis in clinical level.

  • 1. Objectives Due to a lack of detail guidelines for prescriptions to ordinary and pathological symptoms in ${\ulcorner}$DongyiSuseBowon${\lrcorner}$, doctors depend on their own decision when give a prescription. This study aimed to compare ordinary symptoms and pathological symptoms in regards to six prescriptions being applied to Soyangin to utilize them as guidelines in practices. 2. Methods Date were collected from September, 2003 to August, 2004 at the Sasang Constitutional clinic of Pohang Oriental Medicine Hospital. Patients were first asked to fill Out a questionnaire of symptoms that they had at the time of visiting. Data from 273 Soyangin patients whose chief complains got alleviated after taking the prescribed drug were analyzed to examine if there were differences in prescriptions according to ordinary or pathological symptoms complained. 3. Results and Conclusions 1. Hyungbangpaedog-san(Paedog) was given more to the patients having good digestive function than Hyungbangjihwang-tang(Hyungji) and Hyungbangdojeok-san (Dojeok) ; Dojeok was given for bloating symptom compared to Hyungbangsabaek-san(Sabaek). Yangkyuksanhwa-tang(Yangkyuk) and Dojeok were more like for patients with stomachache compared to Paedog. Doghwaljihwang-tang(Dogji) was prescribed to patients complaining frequent voiding compared to Sabaek while Sabaek was given for patients who prefer cold water and feel their body warm compared to other prescriptions. Yangkyuk and Dojeok were prescribed more likely to patients with feeling of suffocation than Sabaek. 2. In symptom comparisons between one prescription and the group of the rest of 5 prescriptions, Paedog was found to be prescribed when patients had good digestive function while Dojeok was given in symptoms cases of indigestion, bloating, constipation and dizziness. Sabaek was applied more for patients having tendency of preferring cold water and feeling of heat body as well as good digestive function. Hyungji was used for patients complaining a symptom of fatigue, in addition Yangkyuk was given to patients who were nervous, sensitive, or impatient when compared to Other prescriptions. Dogji was applied to frequent voiding, insomnia, tingling of extremities, backache or leg pain, or in case of tendency of catching a common cold.

  • Objectives The purpose of this study was to revise Sasang Digestive Function Inventory (SDFI) and improve its validity and reliability using clinical data. Methods The Sasang type and Cold-Heat pattern differentiation by certified clinical specialist and responses to SDFI items were acquired from 419 hospital patients. The revision of SDFI was performed using item analysis and Explorative Factor Analysis (EFA). Furthermore, the validity and reliability of the revised SDFI (rSDFI) were investigated using Confirmatory Factor Analysis (CFA), Internal Consistency and Item Response Theory (IRT). And, clinical significance of the rSDFI was examined for the differentiation of Sasang types and Cold-Heat patterns. Results The number of the SDFI items were modified from 21 to 15. And, the validity and reliability of the rSDFI subscale structure were found to be acceptable. The scores of rSDFI-total and rSDFI-E significantly decreased in the order of Tae-Eum (TE), So-Yang (SY), So-Eum (SE) types, and the rSDFI score of SE type was significantly lower than that of TE and SY types. The rSDFI-total score could differentiate Cold-Heat pattern in both SY and SE types. And the difference of digestive function between Cold and Heat pattern of SE type could be explained with the rSDFI-D score. The rSDFI-total score in Cold pattern significantly decreased in the order of TE, SY, and SE types, and the rSDFI-total score of TE type is significantly higher than that of SE type in Heat pattern. Conclusions Current results demonstrated the reliability, validity and clinical usefulness of the rSDFI in clinical patients. Therefore, rSDFI can be utilized as an objective clinical measure supporting the differential diagnosis of Sasang typology.
