The present study was conducted to predict shelf life of pasteurized milk with analysis of volatile compounds and sensory evaluation of milk to growth of psychrotrophic bacteria. Pseudomonas fluorescens KFRI 00194 inoculated concentration of 10^4 cfu/㎖ to observe of changes on sensory evaluation and volatile compounds of pasteurized milk. The results obtained in these experiments were summarized as follows; The psychrotrophic bacteria number at 4℃ were increased 6.39×10 exp(4)cfu/㎖ until first day and 2.20×10 exp(6)cfu/㎖, 1.17×10 exp(7)cfu/㎖ after 5 and 10days, respectively. The volatile compounds were shown the decreasing tendancies in acetaldehyde, ethanol depending on storage days, especially ethanol contents were significantly decreased between 5 and 10days storage(P<0.05). Diacetyl, 2-heptanone, 2-butanone and 3-methyl-1-butanol were shown the increasing tendencies of contents. Diacetyl, 2-heptanone and 2-butanone were significantly increased between 5 and 10days, 1 and 5days, 5 and 10days and 1 and 5days, respectively(P<0.05). However, 3-methyl-1-butanol was shown a increasing tendancy depending on storage days but the significantly different was not recognized. The changes of sensory evaluation were rapidly decrease from 6.8point first day to 4.2point after 10days and the decrease of organoleptic acceptability was significantly different recognized(P<0.05), excepted of 1 and 2days. The organoleptic acceptability according to increasing of psychrotrophic bacteria numbers were decreased. The organoleptic acceptability depending on changes of volatile compounds were shown to a conversed correlation coefficient with the exception of acetaldehyde and acetone. Especially, 2-heptanone, 2butanone and 3-methyl-1-butanol were gradually decreased of acceptability by the contents.

Paraquat is a bipyridilium nonselective contact herbicide and well-known pulmonary toxicants. Concentrated solution of paraquat may causes severe corrosive injury and multiple system organ failure. It is poorly absorbed from GI tract, but is extremely toxic and so one swallowed mouthful of Gramoxone(about 5ml) will be fatal. We experienced 3 cases of paraquat poisoning through injection and examined pathologic findings, medical records and concentration of paraquat in blood and tissues. We reviewed the mechanism of action of paraquat. pathologic changes of organ system, concentration of compound in the various organ and cause of death in autopsy cases.

Are Spinal GABAergic Elements Related to the Manifestation of Neuropathic Pain in Rat?

Lee, Jae-Hee,Back, Seung-Keun,Lim, Eun-Jeong,Cho, Gyu-Chong,Kim, Myung-Ah,Kim, Hee-Jin,Lee, Min-Hee,Na, Heung-Sik The Korean Society of Pharmacology 2010 The Korean Journal of Physiology & Pharmacology Vol.14 No.2

Impairment in spinal inhibition caused by quantitative alteration of GABAergic elements following peripheral nerve injury has been postulated to mediate neuropathic pain. In the present study, we tested whether neuropathic pain could be induced or reversed by pharmacologically modulating spinal GABAergic activity, and whether quantitative alteration of spinal GABAergic elements after peripheral nerve injury was related to the impairment of GABAergic inhibition or neuropathic pain. To these aims, we first analyzed the pain behaviors following the spinal administration of GABA antagonists ($1{\mu}g$ bicuculline/rat and $5{\mu}g$ phaclofen/rat), agonists ($1{\mu}g$ muscimol/rat and $0.5{\mu}g$ baclofen/rat) or GABA transporter (GAT) inhibitors ($20{\mu}g$ NNC-711/rat and $1{\mu}g$ SNAP-5114/rat) into naive or neuropathic animals. Then, using Western blotting, PCR or immunohistochemistry, we compared the quantities of spinal GABA, its synthesizing enzymes (GAD65, 67) and its receptors (GABAA and GABAB) and transporters (GAT-1, and -3) between two groups of rats with different severity of neuropathic pain following partial injury of tail-innervating nerves; the allodynic and non-allodynic groups. Intrathecal administration of GABA antagonists markedly lowered tail-withdrawal threshold in naive animals, and GABA agonists or GAT inhibitors significantly attenuated neuropathic pain in nerve-injured animals. However, any quantitative changes in spinal GABAergic elements were not observed in both the allodynic and non-allodynic groups. These results suggest that although the impairment in spinal GABAergic inhibition may play a role in mediation of neuropathic pain, it is not accomplished by the quantitative change in spinal elements for GABAergic inhibition and therefore these elements are not related to the generation of neuropathic pain following peripheral nerve injury.

The positive rate of Clonorchis sinensis is the highest among intestinal parasites in the Republic of Korea (Korea). More than 1.2 million people were at risk of C. sinensis infection in Korea in 2012. An intensive control program is being implemented for residents of the 5 major river basins to reduce helminthic infections, including C. sinensis infection. This study evaluated the continuous intensive control program for parasitic diseases including clonorchiasis in areas near the 5 major river basins in Korea over the past 10 years (2011-2020). A total of 335,020 fecal samples (one sample per resident) prepared by the modified sedimentation technic were microscopically examined. Those who expelled helminth eggs were treated with anthelmintics through local health centers and re-examined 3 months later. The overall positive rate of helminths egg was 7.1%. The annual positive rates were dramatically decreased from 14.4% (2011) to 5.9% (2020). The egg positive rate was highest in C. sinensis (5.3%), followed by heterophyid flukes (1.5%) and Trichuris trichiura (0.2%). The prevalence of C. sinensis was significantly higher in males (7.6%) than in females (3.7%), and the highest in the 50-59 years (7.0%) age group. Our results are beneficial to establish prevention and control policies against helminthiases including clonorchiasis in endemic areas in this country.

열등 핵심감정에 대한 질적 사례연구

이희백 ( Lee Hee-back ) 한국동서정신과학회 2017 동서정신과학 Vol.20 No.1

본 연구는 열등감을 핵심감정으로 가진 내담자의 심리적 특징과 반응을 분석하는데 주 목적이 있다. 분석에 사용된 6개의 상담사례는 모두 자발적이었으며 열등감을 나타내는 언어반응을 집합적 질적 사례 연구의 방법론을 활용하여 분석하였다. 그 결과, 모든 사례에서 공통적으로 나타난 감정적 반응으로는 나 자신이 부끄럽다, 창피하다가 핵심적인 심리적 반응이었으며, 가족에 대한 심리적 반응으로는 공통적으로 가족들이 나를 못났다고 생각하고 무시한다고 느끼는 것으로 드러났다. 이러한 심리적 반응은 아동기 가족관계에서의 경험 즉 나보다는 다른 형제를 더 좋아하였고 나에게는 별반 관심과 칭찬, 인정을 해주지 않았다고 느끼는 것으로 분석되었다. 행동적 특징은 자신의 열등한 모습이 들어 날까봐 신경 쓰이고 자신의 모습을 감추고 싶어 타인들에게 자신의 진정한 모습이 드러나는 것을 극도로 꺼리고 자신의 진심을 감추려고 노력한다. 일 또는 학업에 대한 반응으로는 “내가 시작한 일의 결과는 늘 실패로 끝날 가능성이 아주 높다.”라는 비합리적 신념으로 인해 위축되어 일의 효율성이 극도로 저하되는 경향이 강하게 들어났다. 또한 대인관계에서의 반응도 남들 앞에 서는 것이 창피하여 자신의 주장이나 말을 할 수가 없어 자신의 의견을 당당하게 들어내지 못하고 속으로 감추려는 행동으로 인해 대인관계의 의사소통이나 갈등해결에 소극적 태도를 보였다. 이로 인해 자신의 감정을 표현하거나 소통하지 못하고 혼자 마음속에 열등 감정을 품고 있는 것으로 나타났다. 이러한 현상은 현재의 가족원과의 관계에서도 재 경험 되고 있고 타인과의 대인관계에서도 반복적으로 재 경험 되고 있는 것으로 분석되었다. The main purpose of this study is the nuclear feeling of hostility key psychological characteristic of people with a variety of viewing in terms of looks. In order to achieve the this study, researchers counseling cases are collectively qualitative six case studies were analyzed using the methodology. As a result, the nuclear feeling of hostility are classified into six subjects as a common psychological characteristic of people with childhood family relationship experiences, a psychological response for a family, behavioral characteristic, response in work or study, reaction of interpersonal from emotional reactions. As a result, emotional reactions common to all cases were ashamed and embarrassed. The psychological responses to the family showed that the family members felt that they were ignorant of themselves and ignored them. These psychological responses were analyzed to be that they liked other siblings rather than oneself in their childhood family relations and not give interest and praise. The common behavioral characteristics of people with inferiority as core emotions were to worry about their inferiority and want to conceal their appearance. Also, I try to hide my true self from other people. There is a high degree of irrational belief that work or study is likely to end in failure. As a result, there was strong tendency that the activity was shrunk and the efficiency of the work was extremely degraded. In addition, the reaction in interpersonal relationships is also embarrassing to stand in front of others, so that their can not make own argument or say oneself opinion without being heard. Thus, they showed a passive attitude toward interpersonal communication and conflict resolution. Asa result, they were unable to express or communicate their emotions, and were feeling inferior in their minds alone. This experience is now being repeated in life there is, the nuclear feeling of unfair formed in childhood continue to suffer due to, respectively.
