Three German Shepherd dogs (5 years old, 30 kg, male; 4 years old, 23 kg, female; 4 years old, 24 kg, female) with history of acute vomiting, hemorrhagic diarrhea, anorexia and dullness were admitted to veterinary clinic in the military working dogs training corp (MWDTC). All of them showed same symptoms after ingestion the $'PREVNTIC^{(R)}'$ collar to control ecto-parasites infection in field. One dog was operated by gastrotomy and the $5{\sim}6$ pieces of the $'PREVNTIC^{(R)}'$ collar were removed. The dog was completely cured by intensive care within 2 hours after $'PREVNTIC^{(R)}'$ collar ingestion. However, two dogs were operated by gastrotomy and intensive care over 24 hours after $'PREVNTIC^{(R)}'$ collar ingestion but died. In autopsy, the $5{\sim}6$ pieces of hard materials were found in the stomach, and severe thickness, congestion hemorrhage and swelling of the stomach walls and mucous membrane were observed. In these cases, it was suggested that the first aid of treatment such as gastrotomy within two hours after $'PREVNTIC^{(R)}'$ collar ingestion as soon as possible was helpful for attenuating of toxicosis.

Veillonella spp. have been reported to be the most prevalent nitrate-reducing bacterial species in the oral cavity. The purpose of this study was to examine the relationship between the abundance of Veillonella spp. and nitrite production after nitrate ingestion. Bacterial samples were obtained from the tongue surfaces of 50 university students. The predominant Veillonella spp., V. atypica, V. dispar, and V. rogosae were identified and enumerated using real-time polymerase chain reaction (qPCR). Salivary nitrate and nitrite were measured before and 30, 60, and 90 min after ingestion of 100 ml of beetroot juice. Increased nitrite concentrations were observed in all participants, with a mean increase of 0.61 (0.42-1.10) mM expressed as the median (interquartile range). Veillonella atypica was detected in 40 subjects (80%), V. dispar in 48 (96%), and V. rogosae in 48 (96%), at quantities ranging from 1.3 × 102 to 2.8 × 107 CFU/ml per subject. The strengths of the correlations of the log colony forming unit (CFU) values of V. atypica, V. dispar, V. rogosae, and the log CFU value of the three species together with the increase in nitrite levels were 0.091, 0.114, -0.228, and 0.060, respectively, none of which were significant (p > 0.05). Our results indicate that the abundance of Veillonella spp. is not related to salivary nitrite production after nitrate ingestion.

To understand the physiology of a suspension-feeding bivalve and its potential impacts on the dynamics of red tides on tidal flats, rates of clearance and ingestion of Glauconome chinensis were measured as a function of algal concentration, when the bivalve was fed on a nontoxic strain of red tide dinoflagellate Prorocentrum minimum, Cochlodinium polykrikoides or Scrippsiella trochoidea. With increasing algal concentration, weight-specific clearance rate increased rapidly at lower concentrations and after reaching the maximum at ca. 0.2 to 1.0 mgC/L, it decreased at higher concentrations. Maximum clearance rate was nearly equal for different algal species and ranged between 2.1 and 2.6 L/g/hr. Weight-specific ingestion rate also increased at lower algal concentrations but saturated at higher concentrations. Maximum ingestion rate was 2 to 10 fold different with different algal species: S. trochoidea (10.1 mgC/g/hr), P. minimum (3.9 mgC/g/hr), and C. polykrikoides (0.99 mgC/g/hr). Nitrogen and protein content showed that S. trochoidea is the best among the tested three red tide dinoflagellates. The maximum filtration capacity, calculated by combining the data on ingestion rate from laboratory experiments and those from the field for the density of the bivalve and the red tide dinoflagellates was 4.7, 1.4, and 25.3 tons/m2/day for P. minimum, C. polykrikoides, and S. trochoidea, respectively. It is hypothesized that the abundant suspension-feeding bivalves in tidal flats can effectively mitigate the outbreak of red tides.

The present study was conducted to investigate the yields of volume, thiamin and riboflavin from the milk of twenty-five Cesarean-section women, and their ingestion in infants. We measured the consumed volume of human milk of infants by the test-weighing method, and thiamin riboflavin contents were determined by fluorescence spectroscopy during the first 7 days postpartum. Thiamin contents of the milk averaged 24.3, 24.0, 27.4 and 30.2ug/100g. Thiamin and riboflavin contents of the milk both increased during the lactation ps mod(p<0.05). The first secretion of breast milk occurred from the 4th to 5th day postpartum in Cesarean-section women. The consumed volume of human milk was 63, 81, 104 and 133g/day at 4, 5, 6 and 7 days postpartum and the consumed volume of formula milk was 58, 176, 292, 323, 308, 321 and 318g/day at 1, 2, 3, 4, 5, 6 and 7 days postpartum and the consumed volume of formula from the human and formula milk were 26.6, 91.0, 151.0, 172.5, 169.2, 175.9 and 172.9ug/day. Total daily riboflavin ingestion from the human and formula milk were 26.6, 91.0, 151.0, 172.5, 169.2, 175.9 and 172.9ug/day. Total daily riboflavin ingestion from the human and formula milk was 48.7, 166.8, 277.6, 318.2, 312.0, 327.0 and 335.7ug/day at 1, 2, 3, 4, 5, 6 and 7 postpartum. These results suggest that the milk secretion of Cesarean-section women is delayed a few days and the yield volume of milk is less than that of normal delivery women, but thiamin and riboflavin contents of the milk are not different from those of milk of normal-delivery women.

Purpose: Alcohol ingestion is a significant risk factor for injuries. However, the influence of high blood alcohol concentration about the severe traumatic injury is controversial. The aim of study was to analyze the injury severity, prognosis in severe traumatic patients according to alcohol ingestion. Methods: This study was performed retrospectively with severe traumatic patients (Injury Severity $Score{\geq}16$) who visited the emergency department at Pusan National University Hospital from January 2013 to December 2013. Results: In total 98 severe traumatic patients, blood alcohol concentration (BAC) positive group (BAC>30 mg/dl) is 42 (42.90%) patients and BAC negative group ($BAC{\leq}30mg/dl$) is 56 (57.10% )patients. Head and neck injury is significantly high in BAC positive group (35 patients, 83.3%) compared to BAC negative group (33 patients, 58.9%). Comparison of injury severity, outcome and mortality is not significantly different between two groups. Conclusion: In severe traumatic patients, head and neck injury occurred high in BAC positive group. Alcohol ingestion did not influence injury severity, outcome in severe traumatic patients. However, effort to decreasing injury related to alcohol ingestion and prospective multi-center study is needed.

Background: This study presents food ingestion standards for radioactivity that can be applied in nuclear emergency exposure situations, and discusses the validity of the current domestic standards. Materials and Methods: This study derived food ingestion standards for radiocesium and radioiodine using domestic food intake rates and intervention levels, which serve as a basis for determining the necessity of public protective actions, and then compared them with the existing guidelines. Operational intervention levels were also derived using domestic food intake rates, and were compared with those of the International Atomic Energy Agency. Results and Discussion: The derived activity concentrations for food ingestion standards of radiocesium for infants were higher than those in the Act on Physical Protection and Radiological Emergency (APPRE) for all food categories, while for adults, the derived activity concentrations for drinking water and milk appeared to be slightly lower. The derived activity concentrations for vegetables, fruits, and grains were greater than those in the guidelines of the APPRE, while the derived activity concentrations for meat and seafood were similar to those in the APPRE. The derived activity concentrations for radioiodine were greater than both domestic and global standards. The calculated operational intervention levels (OILs) based on domestic food intake rates were greater than the IAEA's default OIL6 values for most radionuclides, except for a few ${\alpha}$-radionuclides. Conclusion: The current domestic guidelines turned out to be conservative overall, compared to the present results that were calculated using domestic food intake rates. It is recommended that the domestic guidelines should be revised and complemented transparently through an in-depth review by stakeholders on a solid scientific basis.

This study was conducted to investigate the effect of ingestion of rice meal with red pepper(Capsicum annuum) as a seasoning upon the plasma gastrin concentration of normal human subjects in Korea. Thirteen normal human subjects including male and female(mean age: 21 years, range: $20{\sim}24\;years$) were studied. After an overnight(about 15 hrs) fast each subject ingested a test meal and a control meal on different days. The test meal consisted of 250 g toiled rice, 250 ml radish soup containing red pepper(dried powder, 3 g), 50 g vegetables and 200 ml barley tea, corresponding to 7.0 g protein, 9.0 g fat and 82 g carbohydrate and the control meal consisted of the same amount as the test meal except that the radish soup was supplied without red pepper. The venous blood samples were drawn before and after the ingestion of meals at the following times: -30, 0, 15, 30, 45, 60, 90, and 120 min for the measurement of plasma gastrin concentration by means of radioimmunoassay. 1) Plasma gastrin concentration in response to the ingestion of control meal without red pepper increased significantly compared with the concentration in fasting state. 2) The increase of plasma gastrin concentration after the ingestion of test meal(containing red pepper) was significantly higher than that after the control meal. It is inferred from the above mentioned results that the ingestion of red pepper as a seasoning has a stimulatory influence on gastrin release in normal human subjects.

To explore the interactions between the mixotrophic dinoflagellate Biecheleria cincta (previously Woloszynskia cincta) and heterotrophic protists, we investigated whether the common heterotrophic dinoflagellates Gyrodinium dominans, Gyrodinium moestrupii, Gyrodinium spirale, Oxyrrhis marina, and Polykrikos kofoidii, and the ciliate Strobilidium sp. were able to feed on B. cincta. We also measured growth and ingestion rates of O. marina and Strobilidium sp. on B. cincta as a function of prey concentration. In addition, these rates were measured for other predators at single prey concentrations at which the growth and ingestion rates of O. marina and Strobilidium sp. were saturated. All grazers tested in the present study were able to feed on B. cincta. B. cincta clearly supported positive growth of O. marina, G. dominans, and Strobilidium sp., but it did not support that of G. moestrupii, G. spirale, and P. kofoidii. The maximum growth rates of Strobilidium sp. and O. marina on B. cincta (0.91 and 0.49 $d^{-1}$, respectively) were much higher than that of G. dominans (0.07 $d^{-1}$). With increasing the mean prey concentration, the specific growth rates of O. marina and Strobilidium sp. on B. cincta increased, but either became saturated or slowly increased. The maximum ingestion rate of Strobilidium sp. (1.60 ng C $predator^{-1}\;d^{-1}$) was much higher than that of P. kofoidii and O. marina (0.55 and 0.34 ng C $predator^{-1}\;d^{-1}$) on B. cincta. The results of the present study suggest that O. marina and Strobilidium sp. are effective protistan grazers of B. cincta.
