Background Some patients who need surgery refuse a blood transfusion because of their religious beliefs or concerns about blood-borne infections. In recent years, bloodless surgery has been performed successfully in many procedures, and is therefore of increasing interest in orthognathic surgery. Methods Ten Jehovah's Witnesses who visited our bloodless surgery center for orthognathic surgery participated in this study. To maintain hemoglobin (Hb) levels above 10 g/dL before surgery, recombinant erythropoietin (rEPO) was subcutaneously administered and iron supplements were intravenously administered. During surgery, acute normovolemic hemodilution (ANH) and induced hypotensive anesthesia were used. To elevate the Hb levels to >10 g/dL after surgery, a similar method to the preoperative approach was used. Results The 10 patients comprised three men and seven women. Their average Hb level at the first visit was 11.1 g/dL. With treatment according to our protocol, the average preoperative Hb level rose to 12.01 g/dL, and the average Hb level on postoperative day 1 was 10.01 g/dL. No patients needed a blood transfusion, and all patients were discharged without any complications. Conclusions This study presents a way to manage patients who refuse blood transfusions while undergoing orthognathic surgery. rEPO and iron supplementation were used to maintain Hb levels above 10 g/dL. During surgery, blood loss was minimized by a meticulous procedure and induced hypotensive anesthesia, and intravascular volume was maintained by ANH. Our practical approach to orthognathic surgery for Jehovah's Witnesses can be applied to the management of all patients who refuse blood transfusions.

The effects of various levels of copper(Cu) intake on the concentrations of copper, iron (Fe) and 3inc(Zn) in rat tissues were studied in growing rats. For different groups the drinking water was supplemented with 0(control), 25, 50, 100 and 200ppm Cu(as copper sulphate) for 1 day respectively. All animal groups were fed with the control diet (Cu contents, 12.8%mg/kg diet) during the experiment. At the end of the 4 week experiment, body weight gain was slightly lower in the Cu supply groups than in control group. Liver and serum Cu were significantly higher in 50, 100 and 200ppm Cu of male and in 200ppm Cu of female than in control groups. Spleen Cu was significantly increased by the supplementation of Cu. Liver and heart Fe of male and heart Fe of female were increased by incresing supplementary Cu levels. In 50ppm Cu group, liver, spleen and kidney Fe of female increased but the others did not. Fe of tissues was different in male and female rats according to Cu levels supplied. Serum Zn of male and female was significantly lower in 50, 100 and 200ppm Cu groups than in control and 25ppm Cu groups. When supplemented with Cu levels there were no significant differences among groups for liver, kidney, spleen and heart Zn as well as heart and kidney Cu.

We studied daily micronutrient intake from vitamin-mineral supplements, health-related life style, clinical case of diseases and food frequency of the Korean middle-aged (40-59 yr, n = 404) to compare the characteristics of non-user (n = 270) and user (n = 134) of vitamin-mineral supplements. Rate of supplement use of the middle-aged was 33.2% and there was significant difference in education level (p = 0.0084) and family income (p = 0.0476) of user and nonuser. Smoking habit (p = 0.0844) and drinking frequency (p = 0.0606) tended to be lower in a supplement user than a non-user. The medical history of a case was significantly higher in users (67.9%) than in non-users (44.4%) (p = 0.001), which suggests that medical history is one of the important motivations of supplement use. Supplement users had the medical history of digestive disease (34.1%), anemia (11.0%) and hypertension (9.9%) in order. Vitamin C was the most frequently supplemented nutrient (81.3%) among vitamin-mineral supplement, and the next orders were vitamins E (73.1%), B$_2$(68.7%) and B$_{6}$ (60.4%). Mean intakes of vitamin B$_1$, iron, selenium, vitamin E, and vitamin C from supplement was 4,260%, 4,030%, 1,660% and 1,330% of RDA, respectively. The supplement users tended to consume most food items including milk ＆ milk products (p ＜ 0.01), rice (p ＜ 0.01), grains (p ＜ 0.05) and cookies (p ＜ 0.01) less frequently than non-users. Conclusively, nutrient intake of vitamin B$_1$, iron, selenium, vitamin E, and vitamin C from supplement was excessively high compared to RDA. We suggest that the toxic effect of excessive supplementation should he informed to supplement user and nutritional education should be focused on the optimal supplement dose.e.

A free-range wild raccoon dog (Nyctereutes procyonoides) was rescued with cachexia. Physical examination revealed generalized hyperkeratosis and alopecia typical of scabies as well as hypothermia (35.6℃). The patient was obtunded and severely dehydrated (10%). Hematological parameters included a low packed cell volume (PCV; 15%) and hemoglobin concentration, leukocytosis, and hypoglycemia. A blood smear revealed different subtypes of hypochromic leptocytes, indicating a regenerative response against severe anemia. This case was initially tentatively diagnosed as a severe anemia due to chronic external bleeding presumed to be caused by scabies-induced skin injuries. Darbepoetin alpha (DPO), iron dextran, and fluralaner were administered at the initial presentation, and supportive care including oxygen supplementation, warming, and nutritional support was provided. However, on day 5, the PCV dropped to 5.9% presumably caused by rapid rehydration due to drinking water ad libitum. DPO was boosted on days 5 and 6 along with daily iron dextran. On day 21, the PCV had recovered to 19.8%, and a blood smear evaluation showed a strong regenerative response. This case shows that even if severe anemia occurs in a raccoon dog, it can be managed with an appropriate response. In particular, since the rehydration rate due to food intake is faster than the hematopoietic response rate of raccoon dogs, the PCV may decrease rapidly in the early stage of treatment; therefore, diagnostic examination and additional medical management for hematopoiesis are necessary.

I. Subject of the study A study on the nutritive value and utilization of powdered seaweeds. II. Purpose and Importance of the study A. In Korea the shortage of food will be inevitable by the rapidly growing population. It will be very important study to develop a new food from the seaweeds which were not used hitherto for human consumption. B. The several kinds of seaweeds have been used by man in Korea mainly as side-dishes. However, a properly powdered seaweed will enable itself to be a good supplement or mixture to certain cereal flours. C. By adding the powdered seaweed to any cereals which have long been staple foods in this country the two fold benefits; saving of cereals and change of dietary pattern, will be secured. III. Objects and scope of the study A. Objects of the study The objects will come under four items. 1. To develop a powdered seaweed as a new food from the seaweeds which have been not used for human consumption. 2. To evaluate the nutritional quality of the products the analysis for chemical composition and animal feeding experiment will be conducted. 3. Experimental cocking and accepability test will be conducted for the powdered products to evaluate the value as food stuff. 4. Sanitary test and also economical analysis will be conducted for the powdered products. B. Scope of the study 1. Production of seaweed powders Sargassum fulvellum growing in eastern coast and Sargassum patens C.A. in southern coast were used as the material for the powders. These algae, which have been not used for human consumption, were pulverized through the processes of washing, drying, pulverization, etc. 2. Nutritional experiments a. Chemical composition Proximate components (water, protein, fat, cellulose, sugar, ash, salt), minerals (calcium, phosphorus, iron, iodine), vitamins (A, $B_1,\;B_2$ niacin, C) and amino acids were analyzed for the seaweed powders. b. Animal feeding experiment Weaning 160 rats (80 male and 80 female rats) were used as experimental animals, dividing them into 16 groups, 10 rats each group. Each group was fed for 12 weeks on cereal diet (Wheat flour, rice powder, barley powder, potato powder, corn flour) with the supplementary levels of 5%, 10%, 15%, 20% and 30% of the seaweed powder. After the feeding the growth, feed efficiency ratio, protain efficiency ratio and ,organs weights were checked and urine analysis, feces analysis and serum analysis were also conducted. 3. Experimental cooking and acceptability test a. Several basic studies were conducted to find the characteristics of the seaweed powder. b. 17 kinds of Korean dishes and 9 kinds of foreign dishes were prepared with cereal flours (wheat, rice, barley, potato, corn) with the supplementary levels of 5%, 10%, 15%, 20% and 30% of the seaweed powder. c. Acceptability test for the dishes was conducted according to plank's Form. 4. Sanitary test The heavy metals (Cd, Pb, As, Hg) in the seaweed powders were determined. 5. Economical analysis The retail price of the seaweed powder was compared with those of other cereals in the market. And also economical analysis was made from the nutritional point of view, calculating the body weight gained in grams per unit price of each feeding diet. IV. Results of the study and the suggestion for application A. Chemical composition 1. There is no any big difference in proximate components between powders of Sargassum fulvellum in eastern coast and Sargassum patens C.A. in southern coast. Seasonal difference is also not significant. Higher levels of protein, cellulose, ash and salt were found in the powders compared with common cereal foods. 2. The levels of calcium (Ca) and iron (Fe) in the powders were significantly higher than common cereal foods and also rich in iodine (I). Existence of vitamin A and vitamin C in the Powders is different point from cereal foods. Vitamin $B_1\;and\;B_2$ are also relatively rich in the powders.'Vitamin A in ·Sargassum fulvellum is high and the levels of some minerals and vitamins are seemed4 to be some influenced by seasons. 3. In the amino acid composition methionine, isoleucine, Iysine and valine are limiting amino acids. The protein qualities of Sargassum fulvellum and Sargassum patens C.A. are seemed to be .almost same and generally ·good. Seasonal difference in amino acid composition was found. B. Animal feeding experiment 1. The best growth was found at.10% supplemental level of the seaweed Powder and lower growth rate was shown at 30% level. 2. It was shown that 15% supplemental level of the Seaweed powder seems to fulfil, to some extent the mineral requirement of the animals. 3. No any changes were found in organs development except that, in kidney, there found decreasing in weight by increasing the supplemental level of the seaweed powder. 4. There is no any significant changes in nitrogen retention, serum cholesterol, serum calcium and urinary calcium in each supplemental level of the seaweed powder. 5. In animal feeding experiment it was concluded that $5%{\sim}15%$ levels supplementation of the seaweed powder are possible. C. Experimental cooking and acceptability test 1. The seaweed powder showed to be utilized more excellently in foreign cookings than in Korean cookings. Higher supplemental level of seaweed was passible in foreign cookings. 2. Hae-Jo-Kang and Jeon-Byung were more excellent than Song-Pyun, wheat cake, Soo-Je-Bee and wheat noodle. Hae-Je-Kang was excellent in its quality even as high as 5% supplemental level. 3. The higher levels of supplementation were used the more sticky cooking products were obtained. Song-Pyun and wheat cake were palatable and lustrous in 2% supplementation level. 4. In drop cookie the higher levels of supplementation, the more crisp product was obtained, compared with other cookies. 5. Corn cake, thin rice gruel, rice gruel and potato Jeon-Byung were more excellent in their quality than potato Man-Doo and potato noodle. Corn cake, thin rice gruel and rice gruel were excellent even as high as 5% supplementation level. 6. In several cooking Porducts some seaweed-oder was perceived in case of 3% or more levels of supplementation. This may be much diminished by the use of proper condiments. D. Sanitary test It seems that there is no any heavy metals (Cd, Pb, As, Hg) problem in these seaweed Powders in case these Powders are used as supplements to any cereal flours E. Economical analysis The price of the seaweed powder is lower than those of other cereals and that may be more lowered when mass production of the seaweed powder is made in future. The supplement of the seaweed powder to any cereals is also economical with the criterion of animal growth rate. F. It is recommended that these seaweed powders should be developed and used as supplement to any cereal flours or used as other food material. By doing so, both saving of cereals and improvement of individual's nutrition will greatly be achieved. It is also recommended that the feeding experiment for men would be conducted in future.

This study aimed to investigate the effects of dietary zinc (Zn), environmental temperatures and Zn${\times}$temperature interaction on growth, feathering score and mineral composition of broilers. A total of 256 d-old Avian male broiler chicks were randomly allocated to a $4{\times}2$ factorial arrangement with four corn-soybean meal basal diets (containing 44 mg Zn/kg) supplemented with 0, 40, 60 mg/kg Zn (Diets 1, 2 and 3, respectively; 0.8% Ca for these three diets) and non-Zn supplementation, 1.6% Ca (Diet 4) and two temperature conditions (low: 26, 24, $22^{\circ}C$ vs. high: 30, 28, $26^{\circ}C$). All birds were given feathering coverage scores for back, breast, wing, under-wing and tail. The wing and tail were further evaluated for the occurrence and severity of defect feathers. Feathers were then pooled for mineral composition analysis. The results showed that in high temperature conditions, broilers fed Zn-unsupplemented, 0.8% Ca ration (Diet 1) had significantly (p<0.05) lower ADFI and ADG (wk 1-6) than birds under low temperature conditions. However, when the birds were fed 40 and 60 mg/kg Zn supplementation (Diets 2 and 3), the ADFI and ADG in both temperature conditions were not significantly different. In low temperature conditions, the ADFI, ADG (p<0.05), all feather coverage (p<0.01) and tail defect scores (p<0.001) of birds fed Diet 4 (excess Ca) were significantly poorer than those fed Diet 1. More Ca (p<0.05) was retained in the feathers of broilers fed Diet 4 under high temperature conditions. Broilers fed the Zn-unsupplemented ration (Diet 1) had significantly higher feather phosphorus (p<0.01) and potassium (p<0.05) concentrations than those fed the 60 mg/kg Zn-supplemented ration (Diet 3). A reduction of feather phosphorus (p<0.01) and potassium (p<0.05) and higher manganese (p<0.05) concentrations were observed in Diet 4 broilers as compared to those fed Diet 1. Under high temperature conditions, broilers had lower iron (p<0.05) and higher manganese (p<0.05) concentrations in feathers. Broilers kept in high temperature conditions had a higher Zn requirement and 40 mg/kg Zn supplementation was sufficient for the birds to achieve optimum growth. Supplemental Zn ameliorated the adverse effect of high temperature on growth and occurrence of tail feather defects. Excess Ca disrupted Zn metabolism to exert a detrimental effect on growth performance and normal feathering and this was elucidated in the birds kept in low temperature conditions.

This study was undertaken to investigate the effect of dietary Fe levels on Cd accumulation in Cd poisoned rats. Forty male weaning Sprague Dawley rats weighing 80-90g were divided into 4 groups(LFe : low Fe, LFeCd : low Fe and Cd, AFe : adequate Fe, AFeCd : adequate Fe and Cd) according to Cd administration(Cd : 0 or 50ppm in drinking water) and Fe levels (Fe : 6 or 40ppm in diet) for 12 weeks. The food intake and weight gain of LFe and LFeCd were significantly lower than those of AFe and AFeCd(p<0.01, p<0.001). The water intake was not affected significantly by Cd and Fe, therefore Cd intake was no significant difference between groups. The Cd accumulation of kidney in LFeCd was significantly higher than those of AFeCd(p<0.001). But the Cd accumulations of brain, liver and spleen were not significantly different between Cd groups and without Cd groups. The serum Cd content and urinary Cd excretion of LFeCd was significantly higher than those of AFeCd(p<0.01, p<0.01). But the fecal Cd excretion of LFeCd was significantly lower than that of AFeCd(p<0.001). The Cd retention, Cd retention rate, and apparent Cd digestibility of LFeCd were significantly higher than those of AFeCd(p<0.001, p<0.001, p<0.001). It was concluded that adequate Fe supplementation have protective effects on the long term Cd poisoning in rats.

The comparative influence of two nanoparticles [viz., superparamagnetic iron oxide nanoparticles (SPION) and nanobarium titanate (NBT)] upon the in vitro and in situ low-density polyethylene (LDPE) biodegradation efficiency of a potential polymer-degrading microbial consortium was studied. Supplementation of 0.01% concentration (w/v) of the nanoparticles in minimal broth significantly increased the bacterial growth, along with early onset of the exponential phase. Under in vitro conditions, ${\lambda}$-max shifts were quicker with nanoparticles and Fourier transform infrared spectroscopy (FTIR) illustrated significant changes in CH/$CH_2$ vibrations, along with introduction of hydroxyl residues in the polymer backbone. Moreover, simultaneous thermogravimetric-differential thermogravimetry-differential thermal analysis (TG-DTG-DTA) reported multiple-step decomposition of LDPE degraded in the presence of nanoparticles. These findings were supported by scanning electron micrographs (SEM), which revealed greater dissolution of the film surface in the presence of nanoparticles. Furthermore, progressive degradation of the film was greatly enhanced when it was incubated under soil conditions for 3 months with the nanoparticles. The study highlights the significance of bacteria-nanoparticle interactions, which can dramatically influence key metabolic processes like biodegradation. The authors also propose the exploration of nanoparticles to influence various other microbial processes for commercial viabilities.
