  • Background: Toluene diisocyanate (TDI) is a highly reactive chemical that causes sensitization and has also been associated with increased lung cancer. A risk assessment was conducted based on occupational epidemiologic estimates for several health outcomes. Methods: Exposure and outcome details were extracted from published studies and a NIOSH Health Hazard Evaluation for new onset asthma, pulmonary function measurements, symptom prevalence, and mortality from lung cancer and respiratory disease. Summary exposure-response estimates were calculated taking into account relative precision and possible survivor selection effects. Attributable incidence of sensitization was estimated as were annual proportional losses of pulmonary function. Excess lifetime risks and benchmark doses were calculated. Results: Respiratory outcomes exhibited strong survivor bias. Asthma/sensitization exposure response decreased with increasing facility-average TDI air concentration as did TDI-associated pulmonary impairment. In a mortality cohort where mean employment duration was less than 1 year, survivor bias pre-empted estimation of lung cancer and respiratory disease exposure response. Conclusion: Controlling for survivor bias and assuming a linear dose-response with facility-average TDI concentrations, excess lifetime risks exceeding one per thousand occurred at about 2 ppt TDI for sensitization and respiratory impairment. Under alternate assumptions regarding stationary and cumulative effects, one per thousand excess risks were estimated at TDI concentrations of 10 - 30 ppt. The unexplained reported excess mortality from lung cancer and other lung diseases, if attributable to TDI or associated emissions, could represent a lifetime risk comparable to that of sensitization.

  • This study was conducted to investigate the immune response of layers fed diets supplemented with excess micronutrients, i.e., vitamin A, methionine, Zn, Cu, and Fe to the inoculation of Newcastle disease vaccine(NDV) or infectious bronchitis vaccine(IBV). The antibody titer against the NDV increased immediately after the inoculation and stayed high during the next 6 wk. On the other hand, The antibody titer against the IBV increased after 4 wk of inoculation The IgM level increased rapidly after 1 wk of NDV inoculation, however, it decreased after 5 wk of inoculation. The IgA displayed similar pattern to that of IgM in response to NDV inoculation. The pattern of IgM change after IBV inoculation was similar to that when layers were treated with NDV. However, IgA level changed earlier than did IgM. The IgG response to the NDV and IBV was very weak compared to the other immune responses. The excess supplementation of micronutrients to the diets of layers inoculated with NDV elicited favorable antibody titer and immune response compared to the layers fed the control diet. The excess Zn, however, allowed the layers to have higher antibody titer for the 4-wk period after NDV injection: after that they showed no effect of extra-Zn. The immune responses of layers fed excess vitamin A, Cu, methionine, and Fe were markedly higher in IgA and IgG than the control layers. The excess Zn, however, did not bring about any favorable result. No difference was detected in IgG level between control and micronutrients-treated groups.

  • This study is about researching DongEuiBoGam by analysing with pattern identification of modern Traditional Korean medical patholgy as more logical, systematic and standardized theory. Disease pattern mechanisms of essence, spirit, qi and blood in NaeGyungPyeb of DongEuiBoGam are these. In Essence, this explain mechanism of disease patterns those are seminal emission, dream emission, spermatorrhea, white ooze. These disease pattern's mechanisms are kidney yang deficiency, kidney yin deficiency, heart yang deficiency, heart yin deficiency, heart qi deficiency, spleen qi deficiency and so on. On viewpoints of viscera and bowels they are related with heart, kidney, spleen. And most of them are deficiency from deficiency-excess Pattern Identification. Classifying disease pattern of qi is about upward, downward movement and more concentrated deficiency than excess pattern. Fright palpitations can be classified heart deficiency with timidity, heart blood and qi deficiency, heart qi deficiency, heart blood deficiency, heart qi movement stagnation, water qi intimidating the heart, phlegm-fire harassing the heart, phlegm clouding the pericardium, and so on. Palpitations can be classified heart blood deficiency, heart yin deficiency, heart deficiency with timidity, heart spleen blood deficiency, spleen qi deficiency, phlegm-fire harassing the heart, intense heart fire, and so on. Forgetfulness can be classified heart spleen blood deficiency, heart spleen qi deficiency, kidney essence deficiency, heart qi deficiency, non-interaction between the heart and kidney, etc. for deficiency pattern, phlegm clouding the pericardium for excess pattern. In Blood just say inside bleeding pattern's category, there are nose bleeding, flopping syncope, qi counterflow, blood vomiting, hemoptysis, spitting of blood, bloody stool, hematuria, and so on. Like these, this study identify pattern of disease in DongEuiBoGam by mechanism of disease theory.

  • Roles of nutrients in controlling plant diseases have been documented for a long time. Among the nutrients having impact on susceptibility/resistance to crop diseases, nitrogen is one of the most important nutrients for plant growth and development. In rice plants, excess nitrogen via fertilization in agricultural systems is known to increase susceptibility to the rice blast disease. Mechanisms underlying such phenomenon, despite its implication in yield and sustainable agriculture, have not been fully elucidated yet. A few research efforts attempted to link nitrogen-induced susceptibility to concomitant changes in rice plant and rice blast fungus in response to excess nitrogen. However, recent studies focusing on phytobiome are offering new insights into effects of nitrogen on interaction between plants and pathogens. In this review, I will first briefly describe importance of nitrogen as a key nutrient for plants and what changes excess nitrogen can bring about in rice and the fungal pathogen. Next, I will highlight some of the recent phytobiome studies relevant to nitrogen utilization and immunity of plants. Finally, I propose the hypothesis that changes in phytobiome upon excessive nitrogen fertilization contribute to nitrogen-induced susceptibility, and discuss empirical evidences that are needed to support the hypothesis.

  • This study evaluated the human health risk in terms of the excess number of mortality and morbidity in the megacity Mumbai, India due to air pollution. AirQ software was used to enumerate the various health impacts of critical pollutants in Mumbai in past 22 years during 1992-2013. A relationship concept based on concentration-response relative risk and population attributable-risk proportion was employed by adopting World Health Organization (WHO) guideline for concentrations of air pollutants like $PM_{10}$, $SO_2$ and $NO_2$. For the year 1992 in Mumbai, it was observed that excess number of cases of total mortality, cardiovascular mortality, respiratory mortality, hospital admission due to COPD, respiratory disease and cardiovascular disease were 8420, 4914, 889, 149, 10568 and 4081 respectively. However, after 22 years these figures increased to 15872, 9962, 1628, 580, 20527 and 7905 respectively, but all of these reached maximum in the year 2006. From the result, it is also noted that except COPD morbidity the excess number of cases from 1992-2002 to 2003-2013 increased almost by 30%; and the excess number of mortality and morbidity is basically due to particulate matter ($PM_{10}$) than due to gaseous pollutants.

  • The present study reviewed the effects of excess iodine intake on thyroid function and the incidence of thyroid disease and discussed the scientific basis for establishing a tolerable upper intake level (UL) of iodine for Koreans. ULs are defined as "the highest level of daily nutrient intake that is likely to pose no risk of adverse effects to almost all individuals in the general population." Koreans consume excess iodine from seaweed, and iodine intake is strongly influenced by seaweed consumption. However, no dose-response data derived from subjects consuming excess iodine frequently but not continuously during a lifetime are available. Therefore, the Korean DRI committee set the iodine UL to reduce the risk of adverse health effects by excess iodine intake for Koreans with distinctive seaweed-eating habits.

  • Lee Dong-won based on the machanism of internal disease founded on Umhwa and Wonki in discriminating internal injury from external. His general idea of discrimination of internal injury from external could be thought as an reinterpretation of the concept from "Neijing", to Triple heater Wonki and ascending and descending of stomach qi. He distinguished between Yin disease and Yang disease and classified into internal and external injury. "Insufficiency of yang brings about cold syndrome." and "An excess of yang brings about heat syndrome." are considered as external infection, and "Insufficiency of yin brings about heat syndrome." and "An excess of yin brings about cold syndrome." as internal injury.

  • Objectives In order to find out the relationship between the Eight Principle Pattern Identification of Cold-Heat, Deficiency-Excess and the Sasang constitution, we analyzed the clinical data from 500 women with menstrual pain and women without menstrual pain. Methods In the previous study, the subject's information of Typology Complexion Pulse and Symptom was collected, and Eight Principle Pattern Identification was executed based on this. Later, the relationship between the Sasang constitution and the Eight Principle Pattern Identification was statistically analyzed. Results and Conclusion 1. The obvious difference between the experimental group and the control group in the patterns of Cold-Heat and Deficiency-Excess is that patients who complain of menstrual pain do not maintain harmony with the yin-yang ratio, it can be said that the patterns of Cold-Heat and Deficiency-Excess can be a Identification standard that significantly obscures the condition of the disease. 2. There was a significant difference between the Sasang constitution and the Eight Principle Pattern Identification of Cold-Heat. There was no significant difference between the Sasang constitution and the Eight Principle Pattern Identification of Deficiency-Excess.

  • Obestity, characterized by an excess accumulation of fat, is a detriment to good health and wellbeing. It is easy for individuals to take on excess fat as soon as enough food and leisure are available in a society, causing an imbalance between energy intake and energy expenditure. Although there has been disagreement as to which side of this energy equation is more important in th epidemic of obesity, both sides are certainly involved. I think the prevalence of obesity begins with infancy. It seems to be relatively constant throughout childhood. Some retrospective studies have suggested that there is a direct progression from a fat chile to a fat adult. Obesity has been associated with excess mortality in many studies. The effect of obesity on cardiovascular disease has not always been an independent one, but has generally been through exacerbation of other rish factors such as hypertention, diabetes, hyperlipedmia, galbladder disease, gout and cancer of the grease and endometrium. The weights of identical twins raised in separate homes have been reported to be similar, thereby suggesting that heredity contributes significantly to weight. Overweight and obesity are by far greater health problems for many people in our society. Therefore in this paper we consider the relationship between body energy balance and problems of obesity. Whatever the weight of the person, the goal of the nutritionist and health care workers is to find solutions that will allow persons to feel better about themselves.

  • This article is for understanding relations between the classifications of gastritis and syndrome differentiation types of Korean Medicine through research on syndrome differentiations of clinically applied gastritis and literature of Korean Medicine. Clinical papers were searched in China Academic Journals(CAJ) of China National Knowledge Infrastructure(CNKI) from 1995 to 2015. Conclusions are as follows. First, disease mechanism of chronic gastritis are qi stagnation, damp stagnation, heat obstruction, blood stasis obstruction, yin damage, damage to collaterals with healthy qi deficiency and pathogenic qi. And qi movement stagnation is shown through the status of chronic gastritis. Second, chronic superficial gastritis belongs to qi aspect syndrome and mainly pathogen excess syndrome. And the key mechanisms are congestion and disharmony of stomach qi sometimes combined with liver depression, food accumulation and dampness-heat. Third, chronic atrophic gastritis belongs to qi-blood syndrome and deficiency-excess complex syndrome with the root of spleen qi deficiency and stomach yin deficiency and the tip of blood stasis, qi stagnation. And key mechanism is damage to collaterals with healthy qi deficiency and toxin-blood stasis. Forth, pathogen excess syndromes are shown at the early stage of chronic gastritis and healthy qi deficiency syndromes after the middle stage. Qi deficiency is shown at the beginning of the disease and yin deficiency at the late stage. And qi deficiency is related with superficial gastritis and yin deficiency with atrophic gastritis.
