An experiment was conducted to investigate the effects of feeding fresh cassava roots on the performance and carcass quality of pigs raised from $15{\pm}1kg$ to 85 kg live weight. Fresh unpeeled cassava roots were chopped into chips and offered separately along with a protein concentrate made up of copra cake and meat and bone meal, and a local mineral-vitamin premix. Commercial pig grower and finisher diets served as control. A total of 24 pigs were used in an incomplete randomized split-plot design experiment. Pigs fed fresh cassava-based diet grew as fast, 0.78 vs 0.77 kg/day, and were as efficient, 3.74 vs 3.77 in converting feed into body weight gain as those fed the commercial control diet. Similarly, there were no differences in carcass quality measured in terms of dressing percentage, 77 vs 77; backfat thickness, 2.76 vs 2.78 cm; loin eye muscle area, 29.2 vs $29.1cm^2$ and in the relative proportions of the different carcass cuts between the two dietary treatments. The use of fresh cassava along with the protein and the local mineral-vitamin premix however, resulted in lowered total feed cost and cost per unit of live weight gain. It is concluded that fresh cassava roots can be fed along with copra cake, meat and bone meal protein concentrate and a local mineral-vitamin premix to fattening pigs with no adverse affects on performance and carcass quality.

This study was performed to provide scientific information for consumers and to increase the quality and consumption of Sullungtang prepared with bone from Hanwoo. The physico-chemical, sensory, nutritional properties of Sullungtang by different parity were investigated. The extracting extents of blood were significantly higher for heifer among Hanwoo cows with different parity(none, the second or the fourth) and for back bones among different bone portions (round, hind shank, arm, fore shank or back bone) (p〈0.05). For Sullungtang extracted from bones of heifer was higher in collagen contents than those extracted from cows with the second or the fourth parity. Sullungtang extracted from bones of heifer and cows with the second parity had significantly higher contents of condroitin and viscosity than those of cows with the fourth parity, however there was no significant difference between heifer and cows with the second parity. In color, L values were significantly high, and a and b values were significantly low for Sullungtang extracted from bones of heifer when compared to those extracted from the other cows with the second parity. The contents of total nitrogen, sodium, or calcium were higher for Sullungtang extracted from heifer than those from the cows with the second or the fourth parity. In amino acid compositions, the percentages of glycine were highest and proline and glutamic acid were followed fro all Sullungtang samples from Hanwoo. The results showed that the overall quality of Sullungtang significantly decreased as the parity increased for Hanwoo cows. The Sullungtang extracted from bones of heifer had the best sensory scores as well as nutritional quality when compared to those extracted from the cows with parity. Therefore, the labeling and price for cow bones should be differently evaluated by their parity and age in marketing system. 본 연구는 한우뼈로 만든 탕의 품질에 대한 소비자의 요구에 부응하고 한우뼈의 부가가치 향상 및 소비 확대를 위하여 산차별에 따른 이화학적, 관능적 및 영양적 특성을 구명하고자 실시하였다. 산차별에 따른 혈액추출정도는 한우 미경산이 유의적으로 높았으며 (p〈0.05), 부위간 비교에서는 잡뼈가 유의적으로 가장 높았다(p〈0.05). 점도는 미경산과 2산차 간에는 유의성이 없었지만 미경산이 높은 경향을 나타내었다. 콜라겐 함량은 미경산이 유의적으로 높았고(p〈0.05), 콘드로이친황산 함량에서는 미경산이 유의적으로 높았으나(p〈0.05), 2산 차이와 유의성이 인정되지 않았지만 높은 경향을 보였다. 명도에서 미경산 추출물이 높은 경향을 보였고 적색도와 황색도는 미경산이 유의적으로 낮았다(p〈0.05). 관능평가는 미경산이 유의적으로 높게 평가되었다(p〈0.05). 총질소, 나트륨 및 칼슘 함량은 미경산 추출물이 유의적으로 가장 높았다(p〈0.05). 한우암소 추출물의 아미노산 조성중 Glycine이 가장 높았고 다음은 Proline, Glutamic acid 순이었다. 이상의 결과를 종합하여 볼 때 전체적으로 한우 미경산우가 우수하였고 산차가 증가할수록 품질이 떨어지는 것으로 나타나 한우암소뼈를 판매시 산차 및 나이에 따라 가격을 차별화 시키는 것이 바람직할 것으로 사료된다.

An experiment was conducted (28 to 44 weeks) to study the laying performance, shell quality, and nutrient retention of White Leghorn layers fed different levels of non-phytate phosphorus (NPP). Six levels of NPP (0.15, 0.18, 0.21, 0.24, 0.27 and 0.30%) at a constant calcium (Ca) level (3.5%) in maize-soya-deoiled rice bran based diets were formulated, and each experimental diet was offered ad libitum for 16 weeks to five replicates with five birds in each replicate. The body weight of WL layers fed diet containing 0.15% NPP was significantly (p<0.05) lower than those fed diet with 0.30% NPP, at 44 weeks of age. However, the hen day egg production, egg weight, daily feed intake and feed consumed per dozen eggs were not influenced by the variation in the NPP levels in the diet. The bone ash content was significantly (p<0.05) higher in the birds fed 0.30% NPP as compared with those fed diets up to 0.24% NPP. Bone ash content was intermediate in the birds fed diet containing 0.27% NPP. The tibia strength followed the same trend as that of bone ash. Dietary NPP content had no influence on serum Ca and protein concentration and activity of alkaline phosphatase. However, serum inorganic P concentration increased linearly with NPP content in the diet. The concentration of P was significantly (p<0.05) higher in the birds fed 0.27% NPP or higher as compared with those fed 0.15% NPP. Levels of dietary NPP had no influence on egg quality parameters like shell wt, shell thickness, shell strength and specific gravity. The retention of nutrients such as DM, N and Ca were comparable among the WL layers fed different levels of NPP. However, the retention of P decreased linearly with increase in the level of NPP in the diet. The retention of P in the birds fed diets up to 0.24% NPP in the diet was comparable, however further increasing the content of NPP (either 0.27% or 0.30%) reduced the retention of P. Based on the results of the present study, 0.15% NPP (180 mg/b/d) in the diets of WL layers is adequate for optimum production performance during 28 to 44 weeks of age, however, WL layers require 0.27% NPP (324 mg /b/d) in the diet for optimum production with better bone mineralization.

Drynariae Rhizorna (DR), an herbal medicine known for its effect to purify blood quality and improve circulation, frequently appears as the main ingredient in prescriptions for bone injuries. Currently, how pharmacologically it contributes to the reformation of bone is unclear. In the present study, the effect of the aqueous extract of DR on bone cells was investigated in vitro for the first time. The human osteoprecursor cells (OPC-I) were incubated in the medium with different concentrations of the aqueous extract of DR and the cell proliferation was studied. When the concentration of DR aqueous extract was $<120{\;}\mu\textrm{g}/ml$, the proliferation of OPC-I was enhanced. However, the proliferation of OPC-I was inhibited by DR extract with the concentrations $>250{\;}\mu\textrm{g}/ml$. Under most treatments, the cells presented very pale expression for cyclooxygenase-2 (Cox 2) protein; a slightly intensified band showed at the highest DR concentration, 1.0 mg/ml during the course of culture. From the results, it was concluded that the aqueous extract of DR was found to directly stimulate the proliferation, alkaline phosphatase (ALP) activity, protein secretion and particularly type I collagen synthesis of OPC-I at dose-dependent manner.

BACKGROUND/OBJECTIVES: We examined the chemical composition and the effect of fermented deer antler on hematopoietic factors in bone marrow cells. MATERIALS/METHODS: For the preparation of fermented deer antler extract (FAB), fermentation was carried out using Bacillus subtilis at $30^{\circ}C$ for 7 days. The hematopoietic effect of FAB was investigated hematopoietic factors in marrow cells. RESULTS: The contents of total sugar, sulfated glycosaminoglycans, and uronic acid and the dry weight gradually increased with fermentation time. The sialic acid content (from 0.14 mg/mL to 0.54 mg/mL) was the highest on the 4th day of fermentation after which it decreased. The proliferating activity of bone marrow cells increased with fermentation times. The levels of various hematopoietic growth factors were determined to verify the beneficial effect of deer antler extract fermented by B. subtilis on hematopoiesis. FAB increased the number of stem cell factors and granulocyte colony-stimulating factor in bone marrow cells. In addition, FAB augmented the burst-forming unit erythroid and total colonies in splenocyte-conditioned medium compared with non-fermented antler extract (NFA). However, FAB did not affect the mRNA levels of erythropoietin, an important factor for erythropoiesis. CONCLUSIONS: FAB, like NFA, did not directly affect hematopoiesis, but contributed to hematopoiesis by stimulating the production of hematopoietic factors.

Bone densitometry is a disease in which bones are easily broken due to metabolic bone disease, and DXA is used as a clinical standard test. Although DXA is a good method with good accuracy and reproducibility, it is frequently subject to test errors in testing and result analysis and analysis. Therefore, it is important to recognize the error issues that radiologists should basically be aware of when performing bone density tests, prevent erroneous diagnoses and treatments resulting from the results, and reduce the unnecessary costs associated with them. aim. The inspection must be carried out if the quality control of the equipment is basically continuously performed well before the inspection. Before starting the examination, the patient's age, sex, race, weight, pregnancy status, and any foreign objects that can be removed should be checked, and the examination should be performed in the correct posture. In addition, it is important to analyze results consistently. Radiologists, who play the most important role in ensuring accurate examinations, need to be aware of the potential for errors in advance and develop the ability to deal with the potential for errors in each examination. For that reason, regular education is considered essential.

The prevalence of intrabony defects in patients with advanced periodontitis stages III and IV is high. These patients usually need both periodontal treatment and orthodontic therapy, including tooth movement through bone defects, to improve masticatory function, aesthetics, and overall quality of life. Clinical practice guidelines recommend periodontal regenerative surgical interventions to resolve these defects and propose initiating orthodontic tooth movement (OTM) once periodontal therapy goals have been met. Surgical interventions using various regenerative technologies like barrier membranes and enamel matrix proteins, combined or not with bone replacement grafts, have proven effective in regenerating lost periodontal tissues. However, the combination of periodontal and orthodontic treatments requires consideration of how periodontal regenerative therapies influence OTM. Studies suggest that regenerated bone may differ in density, composition, vascularity, and cellular activity, potentially affecting the speed and efficiency of OTM, and potential root resorption of moved teeth. Understanding the sequence and timing of implementing OTM after regenerative periodontal interventions is crucial due to their interlinked processes of bone resorption and formation. This narrative review aims to uncover scientific evidence regarding these combined treatments, examining the impacts of different regenerative technologies on OTM and delineating their advantages, limitations, and best practices.

Objectives: The purpose of the study is to investigate the relationship between bone mineral density and remaining teeth in Korean adults. Methods: Using National Health and Nutrition Examination Survey(KNHANES) 5th Year 1(2010), 1,985 adults over 50 years old having bone mineral density test were selected. Male adults were 883, and female adults were 1,102. The raw data consisted of general characteristics of the subjects, bone density data, and oral examination data. The questionnaire consisted of general health survey, laboratory examination study, and nutrition study. Data were analyzed using SPSS 18.0 program for multiple regression analysis, ANOVA, t-test. The variables included general characteristics of the subjects, health behavior, diet habit, and oral health behavior. General characteristics consisted of gender, age, residence area, education level, marital status, monthly income, and vocation. Health behavior consisted of smoking, alcohol drinking, body mass index(BMI), physical activity, and mental health. Diet habit consisted of frequency of meal, milk, coffee, and calcium ingestion. Oral health behavior consisted of frequency of tooth brushing, use of oral health care devices, and oral examination. Systemic diseases were measured by the questionnaire for hypertension, diabetes mellitus, and hyperlipidemia. Bone density was measured in T-score of femoral bone, neck of femur, and lumbar vertebrae. Bone density was classified into normal($T-score{\geq}-1.0$), osteopenia(-2.5 < T-score < -1.0), and osteoporosis ($T-score{\leq}-2.5$). The remaining teeth were measured by the differences between normal teeth and missing teeth. Results: Smoking and age are the most influencing factors on the number of remaining teeth and bone density(p<0.01)(p<0.05). Those who had higher bone density, younger age, and nonsmoker significantly had more remaining teeth. Those who were men, diabetic, lowly educated women, and low birth weighted persons tended to have less number of teeth(p<0.01). Conclusions: The study suggested that there were significant differences between men and women according to the oral health management behavior and systemic disease control. Proper management of the oral health and good quality of bone mineral density can reserve the remaining teeth through the whole life.
