The experiment was carried out on 648 Ross 308 broilers ($40.4{\pm}0.2$ g; 1 d) chickens. It lasted for 28 days to evaluate the effects of phytogenic feed additive (PFA) on growth performance, nutrient digestibility, cecum microbiota, bone minerals contents, meat quality and internal organ weights. The chickens were haphazardly divided into any 1 of 6 dietary treatments (6 replicate pens/treatment; 18 broilers/pen). The experimental diets were: CON, control; T1, CON + 150 ppm PFA; T2, CP 0.5% reduced from basal diet; T3, T2 + 150 ppm PFA; T4, Ca 0.07% reduced + available P (aP) 0.065% reduced from basal diet; T5, T4 + 150 ppm PFA. Overall, broilers fed with T3 diet tended to have higher (P=0.08) body weight gain (BWG), and lower (P=0.05) feed conversion ratio (FCR) than T2 diet. The apparent total tract digestibility (ATTD) of P was lower (P=0.03) in T2 as compared to CON and it was higher (P=0.02) in T3 as compared to T2. There were no differences in meat quality, relative organ weight, and cecum microbiota (P>0.05). The supplementation of PFA showed trends in improvement in ash content in the bone of birds fed T1, T2 and T4 diets compared with CON. Likewise, the supplementation of PFA tended to increase (P=0.07) Ca content in the bone of birds fed T1 diet compared to CON. In conclusion, dietary supplementation with 150 ppm PFA could improve BWG in birds fed protein reduced diet, improve apparent total tract digestibility (ATTD) of P, and the bone Ca contents in broilers.

To investigate the impact of the recently released pediatric reference voxel phantoms (0-, 1-, 5-, 10-, 15-year-old males and females) of the International Commission on Radiological Protection (ICRP) on organ dose estimates for radioactive iodine (RAI) treatment in pediatric patients, we calculated and analyzed pediatric-specific iodine131 S values (r_T ← thyroid) for the 30 radiosensitive organs by conducting Monte Carlo simulations using the Geant4. The gender dependency in the S values was frequently seen for the 15-year-old phantoms with higher S values of female than male. In addition, the age dependency in the S values was observed for most target organs; that is, the S values tend to decrease for older ages (e.g., ~120 times for the gonads between the adult and newborn) due mainly to the inter-organ distances generally longer for older ages. Moreover, we observed that the iodine-131 S values tend to be significantly greater by up to ~145.5 times than those of the stylized phantoms that have been widely used for organ dose estimates of pediatric RAI patients. We believe that the pediatric-specific iodine-131 S values (r_T ← thyroid) of the ICRP pediatric reference voxel phantoms should be beneficial to improve the dosimetry of pediatric RAI patients.

Herbal medicines are increasingly used to treat various diseases and lots of studies have been reported that they had benefits in treating and preventing of diseases. But organic toxicity is increasingly recognized as herbal medicines become more popular in industrialized countries. Some herbal products potentially benefit people with lots of diseases, however these benefits remain generally unproved in humans, and a greater awareness for potential adverse effects is required. A herb containing a wide variety of, mostly unknown, substances may well include some with unwanted effects. This review focuses on emerging organic toxicities that have been observed associated with various herbal preparations involving the liver, kidney, and heart, and patterns of organ injury, potential risk factors for organic toxicities. In addition to the potential for organic toxicities, drug drug interactions between herbal medicines and conventional agents may affect the efficacy and safety of concurrent medical therapy. Appropriate reporting and regulatory system to monitor herbal toxicity are required, in conjunction with ongoing scientific evaluation of the potential benefits of phytotherapy.

Milk-alkali syndrome (MAS), a triad of hypercalcemia, metabolic alkalosis, and renal failure, is associated with ingestion of large amounts of calcium and absorbable alkali. MAS is the third most common cause of hypercalcemia in hospital, after primary hyperparathyroidism and malignant neoplasm. MAS is not often reported in the Korean literature. We describe MAS secondary to intake of calcium citrate for the treatment of osteoporosis with thoracic spine compression fracture. A 70-year-old man presented to our hospital with a 1-week history of general weakness and lethargy. He was found with acute kidney injury (serum creatinine, 4.6 mg/dL), hypercalcemia (total calcium, 14.8 mg/dL), and alkalosis. Laboratory evaluation excluded both hyperparathyroidism and malignancy. Mental status and serum calcium level was normalized within a week after proper hydration and intravenous administration of furosemide. However, he developed aspiration pneumonia, pseudomembranous colitis, and sepsis with multi-organ failure. Despite intensive treatment including inotropics, mechanical ventilation, and renal replacement therapy, he expired with no signs of renal recovery on the 28th hospital day.

This study was to determine whether blue honeysuckle lyophilized concentrated powder (BH) has positive effects on hypothyroidism and related liver damage in propylthiouracil-induced Hypothyroidism. Levothyroxine (LT4)-treated group was administrated by intraperitoneal injection with LT4, while BH or Flos Lonicerae lyophilized aqueous extract (LF)-treated groups were orally administrated for 42 days which two weeks pri or to PTU injection. The changes in organ weight, serum AST & ALT, serum lipid level, liver defense system were measured and the histopathology of the liver was observed. The oral administrations of 125, 250, and 500 mg/kg of BH showed favorable effects compared to LF on hypothyroidism-related liver damages through the enhance antioxidant defense system.

In order to determine the effect of dietary cellulose levels on chick performance, 1-week-old White Leghorn male chicks were fed semi-purified diets containing either 5%, 10%, 15% or 20% cellulose for 3 weeks. All diets were iso-nitrogenous and iso-caloric. Feed intake and body weight were increased as the cellulose level was increased. Feed conversion was lower in the 5% cellulose diet than in the other diets. Compared to the case of 10% to 20% cellulose diets, relative length (per 100 g body weight) of esophagus, duodenum, small intestine and cecum was longer, and relative weight of esophagus, duodenum and crop was also heavier in the chicks fed the 5% cellulose diet. The other internal organs were not affected by the cellulose level. The retention rates of dry matter and nitrogen were lower in the 5% cellulose group than in the other groups. Concentration of carcass phospholipids was higher in the 5% cellulose group, and that of carcass cholesterol was increased as the cellulose level increased. In conclusion, the dietary cellulose level should be more than 5% to give an adequate chick performance, and no ill effect was found even at 20% level.

Ovarian cancer is the tenth most common cancer in Korean female, and the third most common cancer of female reproductive organ after breast cancer and uterine cervical cancer. In spite of develop of conventional treatment, high modality of ovarian cancer comes from difficulty of an early diagnosis. Recent studies revealed that combining conventional and integrative medical treatment can reduce the adverse effect of surgical operation, chemotherapy and radiotherapy. Also it can improve survival rate, quality of life. However there isn't still a systemic clinical protocol for ovarian cancer in Korean medicine. This study will be helpful to establish clinical practice guidelines of Korean Medicine for ovarian cancer. And further studies on integrative ovarian cancer treatment are needed to build the clinical practice guidelines of ovarian cancer.

Internal hernia (IH) is a rare cause of small bowel obstruction occurs when there is protrusion of an internal organ into a retroperitoneal fossa or a foramen in the abdominal cavity. IH can be presented with acute or chronic abdominal symptom and discovered by accident in operation field. However, various kinds of imaging modalities often do not provide the assistance to diagnose IH preoperatively, but computed tomography (CT) scan has a high diagnostic accuracy. We report a case of congenital IH in a 6-year-old boy who experienced life threatening shock. CT scan showed large amount of ascites, bowel wall thickening with poor or absent enhancement of the strangulated bowel segment. Surgical exploration was performed immediately and had to undergo over two meters excision of strangulated small bowel. To prevent the delay in the diagnosis of IH, we should early use of the CT scan and take urgent operation.

For clinical application of radioreceptor assay, we studied preliminarily the distribution of estrogen receptor in various organs of rabbit by a dextran-charcoal method using $6,7-^3H-estradiol$. The results were expressed as binding index, which is the ratio of specific estradiol receptor binding radioactivity to total radioactivity. The materials consist of 5 female rabbits and 3 male rabbits. The results were as follows: 1) Female rabbits The binding index was highest in the uterine tissue. This binding index of the uterine tissue was 9.4 times that of the liver, 21.9 times that of the kidney, 24.6 times that of the brain, 28.1 times that of the lung and 65.7 times that of the muscle. 2) Male rabbits The binding index was highest in the liver and decreased in the order of the kidney, the testis, the lung, the brain and the muscle. It is suggested that the estrogen receptor is not confined to any specific target organ but is widely distributed in the various organs, to a different degree.
