Background: Cardiopulmonary bypass (CPB) induces variable systemic inflammatory reactions associated with major organ dysfunction via polymorphonuclear neutrophils (PMNs). Ulinastatin, a urinary trypsin inhibitor, inhibits PMN activity and reduces systemic inflammatory responses. The aim of this study is to evaluate the effect of ulinastatin on postoperative blood loss and laboratory changes in patients undergoing open heart surgery. Materials and Methods: Between January 2008 and February 2009, 110 patients who underwent atrioventricular valve surgery through right thoracotomy were divided into two groups. Patients received either 5,000 U/kg ulinastatin (ulinastatin group, n=41) or the equivalent volume of normal saline (control group, n=69) before aortic cross clamping. The primary end points were early coagulation profile changes, postoperative blood loss, transfusion requirements, and duration of intubation and intensive care unit stay. Results: There were no statistically significant differences between the two groups in early coagulation profile, other perioperative laboratory data, and postoperative blood loss with transfusion requirements. Conclusion: Administration of ulinastatin during operation did not improve the early coagulation profile, postoperative blood loss, or transfusion requirements of patients undergoing open heart surgery. In addition, no significant effect of ulinastatin was observed in major organs dysfunction, systemic inflammatory reactions, or other postoperative profiles.

The infection characteristics with scuticociliates at on-land rearing farms and hatcheries of flounder, Paralithys olivaceus was investigated during the year of 2001 by juvenile infection routes. When culture tanks for living food organisms such as chlorella, rotifer, and Artemia were searched, scuticocilates were detected both in live and dead rotifer, and at the dregs of culture tank bottoms at almost hatcheries. When rotifer infected with scuticocilates fed on fish larvae, lots of scuticocilate were inhabited at the bottom of fry rearing tanks. After feeding on scuticocilates-infected rotifer on fish larvae, first infection was detected at 10 days after bottom dwelling or 40 days old after hatching. By histopathological examination we confirmed the infection route of eyeball or brain contamination was that the ciliate worms digged through mouth and front part of the dosal fin cuticle, transferred into eyeball along the epithelium and muscle tissue, and reached finally into brain by the muscle and nerve tissue. The infection of internal organs was clarified into two routes. The first route was started from the infection at ventral and anal fin rays by the worms, and reached at the anus and rectum through the epithelium and muscle tissue. The second route was initiated from the infection at urinary organ and reached into the rectum epithelium cells, inner wall of intestine, abdominal cavity, pancreas, kidney, and pancreas. At seed production farms where fish larvae fed on scuticocilate-free rotifer, the worms were not detected not only at the food organisms culture tanks and juvenile rearing tanks but also larval flounder less than 7cm in total length.

This study was performed to investigate the preventive effect of KDD against lead toxicity. KDD of 133, 266, 532 and 1,064 mg/kg were administered twice to the rats of Sprague-Dawley strain and then 300 mg/kg lead acetate was given to times, respectively. 1. The $\delta$-ALAD concentration in the urine showed 10.6 ~16.4 mg/kg in the control group indicated statistical significance for the experimental group II, III, IV, V (p<0.05). Also, the Coproporphyrin concentration had 0.119 ~ 0.226 $\mu$g/ml in the control group indicated statiscial significance for the experimental group V of 10 weeks (p<0.05). 2. The $\delta$-ALAD concentration in the blood showed 13.28 ~ 16.08 ALAD unit in the control group indicated statistical significance for the experimental group I (Pb 300 mg/kg) of 6 and 8 weeks, for the experimental group III, IV of 8 and 10 weeks, and for the experimental group V of 4 weeks (p<0.05). The $\delta$-ALAD concentration of experimental group I (Pb 300 mg/kg) group was inclined to decrease during the experiment period. The $\delta$-ALAD concentration of experimental group I (Pb 300 mg/kg) showed statistical significance for the experimental group II, III, IV, V of 6, 8 and 10 weeks. But, there was no statistical significance in the concentration change of hemoglobin, RBC, WBC, hematocrit, Ca, protein among the experimental groups. In conclusion, this study revealed the preventive effect of KDD against lead toxicity and its mechnism inferred to facilitate lead excretion in urinary following hinderance of lead absorption in the gastric-intestine and organs.

Pharmacokinetic studies on time-course of blood levels, tissue distribution, and excretion of G009, a potential hepatoprotective agent, were performed in male rats after a single oral dose(20mg/kg) of $\^$14/C-labelled G009. The radioactivity concentrations in plasma during 0～3 hours are low, but subsequently increase to a maximum at 12 hours after dosing. $\^$14/C-G009 was well distributed to all tissue. Tissue concentration profiles of radioactivity vary among tissues on time-course after administration. G009(single oral dosage) was distributed and/or absorbed at gastric intestines and excretional organs for initial time of 0-7 hours, and distributed to most tissue at 12-24 hours. In special, the concentration of radioactivity in tiller at 48 hours were 1% of total radioactivity of $\^$14/C-G009 administered. The expired air, urinary and fecal excretion of radioactivity within 24hours after administration were 61.5%, 1.9% and 21.2% of total radioactivity of $\^$14/C-G009 administered. The biliary excretion of radioactivity in rat increased slightly for 0-6 hours after administration. The biliary excretion of radioactivity within 48hours were 1.97%.

Following conclusions are drawn from study about Yukmigiwhangwon through referring to literatures and reviewing in the point of Hyungsang medicine. Yukmigiwhangwon was prescribed by Jeon Eul in order to cure five kinds of flaccidity of infants, but after since then it has been basically applied to symptoms which was caused by deficiency of the kidney not only infants but also adult. The deficiency of kidney is the lack of vital essence and body fluid stored in kidney, it happens because infants are born in the conditions of lack of receiving in the womb. And it happens because adults infringe the rules of life, especially the sexual life. Main symptoms of the poverty of renal functions are emptiness of the brain marrow, dizziness, forgetfulness, tinnitus, deafness, vertigo and dim eyesight, insomnia, the low back and knees aching and limping, heat on the legs, tibia aching, nocturnal emission, dry mouth, reddened tongue and little coating or non coating of the 'tongue, weak blood meridians. the treating method is nourishing Eum and supplementing kidney. In Dongeuibogam Yukmigiwhangwon is mentioned in the parts of vital essence, blood, voice, kidney, urine, eye, ear, the low back, hair, fire, exhaustion syndrome, cough, polydipsia, infant, etc. The shapes which Yukmigiwhangwon is applied to are the Dam Body Doing deficiency of Eum due to excess of Yang, man, infant, Jung type, Fish group, reverse triangular shape, big headed man, big eared man, big mouthed man, man having prominent cheekbones, man having long waist, man having big hips, man with thick hair or white hair, man with bald on the head, etc. In color it is applied to darkish complexion, flushed tip of the nose, or flushed cheek bones.

Background: Bevacizumab-induced proteinuria is known to occur when vascular endothelial cell receptors are blocked, which leads to decreased protein filtration. Although several studies have analyzed the correlation between therapeutic effect of bevacizumab and proteinuria, no conclusion has been established. Methods: In this retrospective study, colorectal cancer patients who received bevacizumab and urinary protein check from January 2015 to December 2016, were included. The incidence of proteinuria and the grade according to Common Terminology Criteria for Adverse Events (CTCAE) 4.0 were evaluated after bevacizumab administration. The primary objective was to correlate proteinuria with overall response rate (ORR) and time to progression (TTP). Primary lesion, metastasized organs, surgery or radiation therapy, chemotherapy were investigated for analysis of risk factors for proteinuria development. Results: A total of 149 patients included in the analysis. Proteinuria occurred 19.5% (n=29) in the study patients; 20 in grade 1, 7 in grade 2, and 2 in grade 3. ORR was 55.2% in the proteinuria group and 51.7% in the non-proteinuria group. There was no difference between two groups (p=0.89). The TTP through the survival curve was similar in both groups (10 months, p=0.97). The risk of proteinuria was high in patients who had liver metastasis (p=0.02) and no surgery (p=0.01). Conclusions: These result indicates that bevacizumab-induced proteinuria expression was not correlated with the therapeutic effect on patients with colorectal cancer. Further analysis is required to find out the correlation between proteinuria and therapeutic effects. The risk of proteinuria was increased from patients who had liver metastasis, and no surgery.

Background: Pharmacogenomics is the study of how genetic mutations in patients affect their response to drugs. Pharmacogenomic studies aim to maximize drug effects and minimize adverse drug events. The Food and Drug Administration and the European Medicine Agency published guidelines for pharmacogenetics in 2005 and 2006, respectively; the Korean Ministry of Food and Drug Safety followed suit in 2015. Methods: This study analyzed pharmacogenomic information in the Korean Ministry of Food and Drug Safety's integrated drug information system to evaluate whether domestic pharmaceutical products reflect the current research on pharmacogenomic differences. Results: In June 2020, the Korean pharmacogenomic database contained genomic data on 90 compounds. Of these, 45 compounds were classified as "Antineoplastic and immunomodulating agents." The other 45 non-antineoplastic agents were in the following categories: Anti-infectives, Mental & behavior disorder, Hormone & metabolism related diseases, Cardiovascular system, Skin & subcutaneous tissue disease, Genito-urinary system and sex hormones, Blood and blood forming organs, Nervous system, Alimentary tract and metabolism, Musculo-skeletal system, and Other conditions including the respiratory system. In addition, 30 additives unrelated to the main ingredient were associated with genetic precautions. Conclusion: This study showed that antineoplastic and immunomodulating agents accounted for half the drugs associated with pharmacogenetic information. For antitumor and immunomodulatory drugs, genomic tests were recommended depending on the indication; this was in contrast to genomic testing recommendations for non-antineoplastic medications. Genomic tests were rarely requested or recommended for non-antineoplastic medications because the relationships between genotype and efficacy among those drugs were relatively weak.

A 6-year-old intact male Cane Corso dog weighing 40 kg with a 2-month history of dysuria, dyschezia, anorexia, intermittent panting, and penile discharge presented to the Veterinary Medical Teaching Hospital of Jeju National University. Examination revealed a giant paraprostatic cyst (PPC) that occupied a large part of the abdomen and caused displacement of organs. Radiography, ultrasound, and computed tomography (CT) scans confirmed that the PPC had spread to the pelvic regions. Subtotal resection was performed, leaving two sites with PPC remnants. One site was the prostate gland, which communicated with, and adhered to, the PPC; the other site was the pelvic region, where the PPC had spread. The reason for leaving two remnants was that an anatomical approach for complete resection was difficult, and to avoid complications associated with prostatic urethra damage. Routine omentalization and castration were performed. Partial cystectomy was performed because of the presence of a diverticulum-like lesion in the ventral part of the urinary bladder. The patient's clinical symptoms, including dysuria, completely resolved, and voluntary urination was possible 1 day post-operatively. Histopathological examination revealed osseous metaplasia of the PPC. The patient was well-managed and had no post-operative complications or recurrence until day 180 of follow-up.

Background: The reference dose coefficients (DCs) of the International Commission on Radiological Protection (ICRP) have been widely used to estimate organ doses of individuals for risk assessments. This approach has been well accepted because individual anatomy data are usually unavailable, although dosimetric uncertainty exists due to the anatomical difference between the reference phantoms and the individuals. We attempted to quantify the individual variation of organ doses for photon external exposures by calculating and comparing organ DCs for 30 individuals against the ICRP reference DCs. Materials and Methods: We acquired computed tomography images from 30 patients in which eight organs (brain, breasts, liver, lungs, skeleton, skin, stomach, and urinary bladder) were segmented using the ImageJ software to create voxel phantoms. The phantoms were implemented into the Monte Carlo N-Particle 6 (MCNP6) code and then irradiated by broad parallel photon beams (10 keV to 10 MeV) at four directions (antero-posterior, postero-anterior, left-lateral, right-lateral) to calculate organ DCs. Results and Discussion: There was significant variation in organ doses due to the difference in anatomy among the individuals, especially in the kilovoltage region (e.g., <100 keV). For example, the red bone marrow doses at 0.01 MeV varied from 3 to 7 orders of the magnitude depending on the irradiation geometry. In contrast, in the megavoltage region (1-10 MeV), the individual variation of the organ doses was found to be negligibly small (differences <10%). It was also interesting to observe that the organ doses of the ICRP reference phantoms showed good agreement with the mean values of the organ doses among the patients in many cases. Conclusion: The results of this study would be informative to improve insights in individual-specific dosimetry. It should be extended to further studies in terms of many different aspects (e.g., other particles such as neutrons, other exposures such as internal exposures, and a larger number of individuals/patients) in the future.

생후 $40{\pm}5$ 일된 젖떨어진 Albino Rat female male 각각 30마리를 크게 Alanine(AL)과 Aminoethylphosphonic acid(AEP) group으로 나누고 각 group을 다시 각각 2 group으로 나누어 female male Alanine 0.1%, female male Alanine 0.2%와 female male AEP 0.1%, female male AEP 0.2% 합(合) 8 group으로 나누어 14 주동안 실험한 결과의 요약은 다음과 같다. 단백질 효율과 뇨중 질소배설량에 어떤 유의적인 차이가 없음으로 AEP도 다른 일반적인 Amino acid와 같은 정도로 체내에서 이용됨을 알 수 있다. AEP의 첨가로 인한 p의 이용율의 변화 유무를 판정하기 위하여 뇨중 p의 함량을 측정한 결과 모든 group사이에 유의성이 없었음으로 alanine 첨가 group에서나 AEP 첨가 group에서나 같은 정도로 체내에서 이용됨을 알 수있으나 AEP의 첨가로 인한 Dietary Phosphorus함량이 높음으로 인하여 체내 보유량이 많다는 것을 알 수 있으며 이는 blood phosphorus 함량측정을 해본 결과와 일치함을 알 수 있다. 간질소 함량을 측정하여 본 결과 AEP 첨가가 간질소 함량을 높일 수 있으며 0.2%쪽이 더 많은 양을 간에 보유할 수 있다는 것을 알았다. 간지방 함량도 간질소 함량과 같은 방향으로 나타났으며 조직 검사로 fat lumps를 발견할 수 없었으므로 AEP 첨가가 fatty liver의 요인이 될 수 없다는 것을 알 수 있다. Amino acid의 생물학적 가치와 Amino acid의 조성사이에는 현저한 관계가 있어 양적으로 충분한 단백질을 섭취한다 하더라도 섭취한 단백질이 함유하고 있는 Amino acid의 종류 및 각종 Amino acid의 비율에 따라서 소화에 현저한 차이가 있어 생물학적 기능이 다르다는 것이 Oser와 그외 여러 학자들에 의하여 보고되었다. 이 보고에 비추어 보아 0.2% diet에서 Amino acid의 장내 흡수시 imbalanced condition을 초래 한 것으로 본다.
