Thirty six barrows with an initial body weight of 28 kg were used to determine the effect of two dietary Se sources and a wide range of Se levels encompassing 0.3, 1.0, 3.0, 5.0, 7.0, and 10.0 mg/kg Se. The organic Se form was a Se-enriched yeast product, whereas the inorganic Se source was sodium selenite. The experiment was a $2{\times}6$ RCB design conducted in three replicates. Each barrow was placed in an individual metabolism crate and provided their dietary treatment and water on an ad libitum basis for a minimum 2 wk period, whereupon feed intake was adjusted to a constant intake within replicate at approximately 90% of intake for a 4 d adjustment period. Urine and feces were subsequently collected for a 7 d period and analyzed for Se and minerals. The results demonstrated that urinary Se was approximately 25% higher when pigs were fed sodium selenite (p<0.01), whereas fecal Se was lower by 25% (p<0.01). Se retention tended to be higher when organic Se was provided (p>0.15). Urinary Se increased as dietary Se level increased for both Se sources but increased more and at a high rate when sodium selenite was fed resulting in an interaction response (p<0.01). Fecal Se increased linearly as the dietary level of both Se sources increased, but the fecal Se from organic Se increased at a faster rate resulting in an interaction response (p<0.01). Se retention increased linearly (p<0.01) as dietary Se increased for both Se sources. The apparent digestibility of Se increased by Se level when pigs were fed sodium selenite, but not when the organic Se source was provided resulting in an interaction response (p<0.05). Retention of consumed Ca, Zn increased when pigs were fed organic Se (p<0.05) whereas P and Na retention were higher when the inorganic Se was provided. Mineral retention was not affected by dietary Se level except P. These results suggest that Se excretion by urine was the main route of excretion when pigs were fed sodium selenite but the fecal route when Se-enriched yeast was provided. The excretion of Fe, Zn, Mn, and Cu via urine and feces was not affected by high dietary Se level or dietary Se sources.

The purpose of this study was to identify the prevalence of urinary incontinence and its relating factors elderly communities. Subjects of this survey consisted of 877 elderly women and men in one Kun. Korea, who were over 60 years old. The design for this study was descriptive: the subjects were interviewed by well trained investigators from July 9. 1999 to July 20. 1999. During that survey period, the subjects were interviewed with a structured questionnaire. The data were analyzed by frequency, percentage, $X^2-test$. T-test using an SAS program. The results of the study were the following: 1. The prevalence rate of urinary incontinence was 20.1 %. of the total. The types of urinary incontinence were mixed incontinence 44.3%. stress incontinence 38.1%. and urge type incontinence 17.6%. 2. The relating factors of urinary incontinence were as follows: 1) 33.5% of UI(urinary incontinence) subjects reported urine loss once a month. twice or three times a week 23.3%. one or two times a day 17.0% 2) 38.1% of elderly reported only 1 to 2 drops. 1 t-spoon 36.9%. 1 T-spoon 15.9% 3) The volume of urine loss registered by changing underwear was 63.1 %. no necessity of changing underwear was 22.1 %. or using some type of pads was 13.1%. 4) 62.5% of UI subjects never discussed their UI problem with other people. 73.9% of the total had never experienced any treatment for their UI problem. The reasons for not receiving medical cure were their typical conception about urinary incontinence taking UI as a normal part of aging 76.2% and due to their bad financial situation 9.2%. 3. Women had more prevalence of UI than men (p=0.01), and it was found that the worse the subjective health state. the higher the prevalence of UI (p=0.001). However. there was no statistical difference in daily frequency of UI (p>0.05). The more nocturnal incontinence (p=0.001), the more intermittent stream experience (p = 0.01), the more retention experience (p = 0.01), and the more incomplete the emptying experience (p=0.001), the higher the prevalence of UI. 4. UI groups had lower ADL scores than non UI groups(p=0.01). The level of depression in the group of urinary incontinence was significantly higher than that of non incontinence group (p=0.0001). As shown above, the elderly people suffering from UI haven't been treated properly: their subjective health state and their ADL competence was lower, and their depression level was higher than non UI groups. Therefore, the development of a proper urinary incontinence management program are required so that they can lead more healthy lives. Also continual case studies for the elderly people with UI are necessary.

It has been reported that boron may be beneficial for optimal calcium metabolism and, thus, optimal bone metabolism. Therefore, we designed a study to determine the effect of boron supplementation on Ca and bone metabolism in rats. The rats of 80-l40g body weight were given a control(0ug), 5$\mu\textrm{g}$, 10$\mu\textrm{g}$, 20$\mu\textrm{g}$, 40$\mu\textrm{g}$, or 80$\mu\textrm{g}$ boron supplement per Is diet for 4-weeks. The results are summarized as follows. There were no differences in total food intake and weight gain among the experimental groups. fecal Ca excretion, urinary Ca excretion, apparent Ca absorption, Ca retention, serum alkaline phosphatase activity, and urinary hydroxyproline were not affected by boron supplementation. There was no difference in serum creatinine. Whereas, urinary creatinine excretion was increased with increasing boron supplementation, and conse-quently creatinine clearance was increased with boron supplementation. No differences were found in length, weight, density, Ca content of femur and scapular. The findings suggest that boron supplementation was not effective in Ca and bone metabolism in growing rats fed normal Ca diet. (Korean J Nutrition 31(6) : 1039-1048, 1998)

The purpose of this research was to investigate the effect of caffeine levels on calcium utilization in rats of different age and sex. Calcium utilization was compared in rats of different age(4 weeks and 10 months) and sex that were fed various levels of caffeine (0, 3.5, and 7mg/100g body weight) for 3 weeks. There was no significant difference in feed intake, serum calcium level, and ash content in tibia among the groups. Fecal calcium excretion was lower in young rats than in adults, Urinary calcium excretion significantly higher in the caffeine groups than that in the no-caffeine group. Daily retention and apparent absorbability of calcium in young rats were higher than those in adult rats. However, there was no significant difference among groups of different sex and caffeine levels. The results of this study suggest that caffeine consumption promotes urinary calcium excretion.

A retrospective study was performed to evaluate the effects, and side effects, of epidural analgesia for postoperative pain relief of 2,381 surgical patients who received general-epidural, or epidural anesthesia only. Anesthesia records, patients charts, and pain control records were reviewed and classified according to: age, sex, body weight, department, operation site, epidural puncture site, degree of pain relief by injection mode & epidural injectate, and side effects(including nausea, vomiting, pruritus, urinary retention and respiratory depression). The results were as follows: 1) From the total of 2,381 patients, there were 1,563(66%) female patients; 1.032(43%) patients were from Obstetrics and Gynecology. 2) Lower abdomen, thorax, lower extremity and upper abdomen in the operation site; and lumbar, upper, lower thoracic in puncture site were order of decreasing frequency. Length of epidural injection for pain relief averaged $1.72{\pm}1.02$ days. 3) Ninety three percent of the patients experienced mild or no pain in the postoperative course. Analgesic quality was not affected by the kind of epidural injectate. 4) Nausea occurred in 3.2% of all patients, vomiting in 1.1%, pruritus 0.9%, urinary retention 0.6%, respiratory depression 0.08%. 5) Frequency of nausea was higher with female patients compared to male patients(p<0.05). 6) Pruritus frequency was higher with male patients than female patients(p<0.05); and more frequent with patients who received epidural injection with morphine than patients who received epidural injection without morphine(p<0.01). 7) Urinary retention was higher in female patients, and more frequent with patients who had received epidural injection with morphine than epidural injection without morphine(p<0.05). 8) There were two cases of respiratory depression. The course of treatment consisted of: cessation of epidural infusion, then administration of oxygen and intravenous naloxone. We conclude that postoperative epidural analgesia with a combination of local anesthetics and opiate is and effective method for postoperative pain relief with low incidence of side effects. However, patients should be carefully evaluated as rare but severe complications of respiratory depression may ensue.

This study aimed to verify the nutritional and curative effects of protein hydrolysate in rats with cysteamine-induced duodenal uncer. Duodenal ulcer rat model was established by intraperitoneal injections of cysteamine. Sprague-Dawley, female rats weighing approximately 200g were intraperitoneally injected twice cysteamine(13mg/100g BW) at intervals of 3h per day. This procedure was repeated 3$\times$at intervals of 3d. Animals fed on 10% casein diet for infection periods. After last injection, 4 kinds of diets(10% casein, 20% casein, 10% casein hydrolysate, 20% casein hydrolysate) were given. Gastric montility, trypsin activity in gastrointestinal content, retention rate of nitrogen, plasma total protein, albumin, amino-N, urinary urea nitrogen, creatinine and hydroxyproline were analyzed for nutritional effects of dietary nitrogen levels(10%, 20%) and sources(casein, casein hydrolysate). In duodenal ulcer rat model, there was no differences between 20% casein diet and 20% casein hydrolysate in the view of severeness of ulcer, gastric emptying rate, serum total protein, serum albumin, plasma $\alpha$-amino-N, UUN, creatinine excretion, GFR, nitrogen retention. On the other hand, rats on 10% casein hydrolysate diet group had more curative effect of the ulcer, higher plasma albumin concentration and nitrogen retention than 10% casein diet group. The casein hydrolysate diet group was lower trypsin activity in small intestinal content than the casein diet group, at both nitrogen levels(10%, 20%). The results suggest that protein hydrolysate be applied in diet therapy for the patients with gastrointestinal ulcer.

COVID-19 infection heightens the risk of thromboembolism. To see the similarities between the COVID-19 infection and Taeyang blood retention pattern, we conducted a PubMed search using specific terms related to blood circulation issues in the context of COVID-19, summarizing findings from 13 cases and 4 observational studies involving actual patients. Patients with COVID-19 are at risk of blood coagulation due to factors such as viral-induced cytokine storms, vascular endothelial dysfunction, reduced mobility in bedridden or isolated individuals, and resulting constipation. Additionally, cytokine storms and severe inflammation can lead to delirium in COVID-19 patients. The Taeyang blood retention pattern manifests as symptoms arising from delirium and an increased blood coagulation tendency in patients with a robust immune response. According to the Sanghan theory, certain herbal treatments can alleviate symptoms in patients with a tight lower abdomen who do not experience urinary issues. Studies show that components like Persicae Semen and Rhei Redix et Rhizoma in these prescriptions enhance blood circulation and reduce hypercoagulability. Additionally, these treatments aim to promote blood flow by relieving abdominal pressure through facilitating bowel movements. The excessive inflammation and heightened blood coagulation tendency in COVID-19 resemble the Taeyang blood retention pattern, although they are caused by different pathogens. Reinterpreting classical oriental medicine's principles in a modern context may enhance our understanding of traditional East Asian Medicine and foster future developments.

Fenfluramine, an anorectic agent, is widely abused as a diet pill in Korea because it is freely marketed in China without any regulation. The optical isomers of fenfluramine hav e different phamacological actions: d-form is used as an anorectic agent, while l-form as a neuroleptic agent. To investigate the metabolism when racemic fenfluramine was administered orally, the urinary excretion of fenfluramine was studied in rats. The enantiomeric separation of fenfluramine was performed on achiral column by gas chromatography using (S)-N-(trifluoroacetyl)-l-prolyl chloride (TFP) as a derivatizing agent. After administration of 15mg/kg of racemic fenfluramine to rats, d-, l-fenfluramine and its metabolites d- and l norfenfluramine in urine were determined by chromatographic separation of TFP derivatives on DB-1 at retention time of 11.2, 11.8, 8.4 and 8.6 min respectively. Urinary recoveries of d and l-fenfluramine in rat were 0.42-5.9O% and 0.18-1.20% respectively in urine specimens collected during first 24hr. The comparison in the levels of isomers showed that d- fenfluramine were higher than l-form, while d-norfenfluramine were lower than l-form. The ratios between parent compound and metabolite revealed that d-norfenfluramine to d-fenfluramine ranged from 1.0 to 4.4, while the ratio of l-norfenfluramine to l-fenfluramine was 8.2-21.1 indicating that l-fenfluramine is metabolized faster than the d-isomer.

This study evaluated the Comparison of the Effectiveness of Pelvic Floor Muscle exercise and Biofeedback treatment for Genuine Stress Incontinence I assigned 60 participants to 2 groups : 30 to the pelvic floor muscle exercise group and 30 to the biofeedback group. Treatment protocol lasted for 6 weeks. Peak pressure, and duration time of pelvic muscle contraction were evaluated by a perineometer. Lower urinary symptoms, sexual matter and life style scores were achieved by using Jackson's scale. The treatment efficacy of the pelvic floor muscle exercise is compared with the biofeedback group and the main results of the comparison are as follows : 1. Pelvic muscle contraction 1) The peak pressure in the biofeedback group was significantly increased(P＝0.000). 2. The frequency and quantity of incontinence 1) The frequency of incontinence in the biofeedback group was significantly decreased(P＝0.000). 2) The quantity of incontinence in the biofeedback group was significantly decreased(P＝0.000). 3. The lower urinary symptoms Daily frequency(P＝0.000), nocturia(P＝0.000), urgency(P＝0.000), bladder pain(P＝0.000), unexplained incontinence(P＝0.048), wearing protection(P＝0.022), changing outer clothing(P＝0.005), hesitancy(P＝0.008), intermittent stream(P＝0.000), abnormal strength of stream(P＝0.004), retention(P＝0.000), incomplete emptying(P＝0.000), and inability to stop mid stream(P＝0.006) of the lower urinary symptoms in the biofeedbatk group were significantly decreased. 4. The sexual matters The dry vagina (P＝0.004) and pain during sexual Intercourse (P＝0.002) in the biofeedback group was significantly decreased. 5. The life style The fluid intake restriction(P＝0.007), affected daily task(P＝0.003), avoidance of places & situation(P＝0.003), interference in Physical activity (P＝0.002), interference in relationship with other people(P＝0.01), and feeling about the rest of life with urinary symptom(P＝0.000) in the biofeedback group were significantly decreased. In conclusion, the biofeedback treatment was more effective than the pelvic floor muscle exercise in genuine stress incontinence.
