  • ${\beta}$-Carotene has been known as an effective quenching agent of singlet oxygen and the carotenoid pigments in general are expected to protect cells against photosensitized oxidations. We are determined the quenching rate constants of several Ketocarotenoids including capsanthin, capsanthin diester, astaxanthin and fucoxanthin, and the relative quenching actiyities against singlet oxygen were compared with those of ${\beta}$-carotene and reported carotenoids. Nevertheless the ketocarotenoids exhibited lower quenching rate constants than ${\beta}$-carotene, they showed more pronounced protective activitives than ${\beta}$-carotene against photohemlysis induced by singlet oxygen. Among the ketocarotenoids investigated, fucoxanthin indicated a significant protective activity for the cell. The results suggested that. 1) 1O2 may be alikely initiator of photohemolysis, but this reaction is followed by slow dark reactions involving secondary reactive species. 2) For protection of RBC against photodynamic action with carotenoids, carotenoids having functional groups such as -C=0 and -OH groups are most efficient. This suggests that partition of carotenoids between the buck and the mombrane and/or their specific binding to membrane proteins are more critical for the photo-protection by carotenoids than is a diffusional quenching of 1O2.

  • This study was performed to investigate nutritional intakes and preference food and blood composition of female college students of premenstrual syndrome. Based on physical measurement test results, both groups showed no noticeable difference and both groups were within the normal range according to body composition analysis. In terms of nutrients consumption, results showed nutritional intakes more than EAR(estimated average requirements) included phosphorus>vitamin $B_6$>vitamin $B_1$, while nutritional intakes less than EAR were vitamin A>vitamin $B_6$>calcium>folic acid. A significant difference was observed for vitamin C intake(p<0.05). The overall mean values of basic blood(WBC, RBC, Hct, and Hb), sex hormone(Estrogen, Progesterone), aldosterone, cortisol, Cu, Zn, and Ca, Mg indices in female college students were within the normal range and there was no significant difference between the PMS group and the Normal group. In conclusion, vitamin C intake of the PMS group showed a level of 84.8% EAR. Therefore vitamin C supplement can be beneficial to relieve the PMS Syndrome.

  • To estimate the source of variance components for some hematological parameters and assess the utility of the conventional population-based reference interval, this study computed index of individuality for blood samples, which were from 13 dogs drawn once weekly for 4 consecutive weeks. Results were subjected to nested analysis of variance. For all parameters measured between-dog variations were greater than within-dog variation. Except for the parameters RBC and MCHC the index of individuality was <1.4. The low reliability coefficient and high index of individuality of ${\leq}0.8$ were found for the majority of hematological parameters. In practical term, the present study indicated that use of hemogram profiles alone in the evaluating clinical state of a single patient should be avoided because of their physiological or natural random variations, and that comparing a single measurement on the blood analytes from an individual dog to the conventional population-based reference range may be too insensitive to detect any significant changes in the blood components of that particular dog. A single measurement may not characterize an individual's average concentration of the parameters even shortterm period.

  • The study investigated the changes in growth performance, hematological parameters, plasma components, and stress indicators of juvenile starry flounder, Platichthys stellatus, depending on varying exposure to hexavalent chromium. P. stellatus was exposed to waterborne chromium at 0, 50, 100, 200, and 400 ppb for 4 weeks. The result showed that Cr exposure resulted in decreased daily length gain (DLG), daily weight gain (DWG), condition factor (CF), and hepatosomatic index (HIS) in P. stellatus. In terms of hematological parameters, red blood cell (RBC) count, hematocrit (Ht), and hemoglobin (Hb) significantly decreased at 400 ppb after 2 weeks. In terms of plasma components, inorganic analysis was unchanged and cholesterol, an organic component, considerably increased at 400 ppb after 4 weeks. Plasma enzyme components including glutamic oxalate transaminase (GOT) and glutamic pyruvate transaminase (GPT) were significantly increased. Stress indicators such as cortisol and glucose were notably increased over 100 ppb after 4 weeks with increasing chromium concentration. The results indicate that exposure to waterborne Cr induced toxic effects on growth, hematological parameters, plasma components, and stress indicators.

  • Henoch-$Sch{\ddot{o}}nlein$ purpura (HSP) is a systemic vasculitis characterized by purpura, arthritis, abdominal pain, and nephritis. Gastrointestinal involvement can manifest as pain, intussusception, intestinal bleeding, and intestinal perforation. We report a case of fulminant HSP at an age of eight in 1994, with multiple complications of intra-thoracic bleeding, massive intestinal perforation, nephritis, and various skin rashes. The brisk bleeding findings of intestinal on Technetium-99m-labeled red blood cell scan ($^{99m}Tc$ RBC scan) were well matched to those of the emergency laparotomy and the resected intestine. The patient's abdominal conditions improved gradually but nodular skin eruptions developed newly apart from improving preexisting lower limb rashes and the urine findings continued abnormal, so skin and kidney biopsy were done for the diagnosis. After cyclosporine therapy, skin eruptions and urine findings returned to normal gradually. On a follow-up after 25 years in 2019, the patient is 33-year-old, healthy without any abnormality on blood chemistries and urine examination.

  • A new diatom species, Mayamaea vietnamica sp. nov., is described from Cát Tiên National Park in Vietnam. This species was discovered and described from soil samples. Algae from soil ecosystems in Vietnam are almost unknown. The new species is described on the basis of an integrated approach with molecular and morphological data, and comparison with similar species. In terms of molecular data, 18S rDNA (including V4 domain), and partial rbcL plastid genes show M. vietnamica sp. nov. is most closely related to M. terrestris N. Abarca and R. Jahn, and together they form a monophyletic group relative to other members of the genus. M. vietnamica sp. nov. differs from other species in the genus by the number of striae and areolae in 10 ㎛, number of areolae per stria, as well as shape and presence or absence of axial and central areas.

  • Immune-mediated hemolytic anemia (IMHA) is autoimmune disease which is anemia caused by own immune system destroying the red blood cells (RBC). It can be diagnosed with spherocytosis, positive auto-agglutination of RBCs and direct antiglobulin test (DAT, Coomb's test). The treatment for IMHA are blood transfusion, immunosuppressive agents including glucocorticoids and other supportive therapies. Danazol is synthetic androgen that has effect of interfering the autoimmune reaction to RBCs. It can be used as an adjunctive agent in addition to glucocorticoids. To investigate its effectiveness, the medical records of 10 IMHA-diagnosed dogs were evaluated. All subjects were treated with blood transfusion, prednisolone, mycophenolate mofetil, and intravenous human immunoglobulin G. Additionally, 6 subjects were administered with danazol and 4 subjects were not. The results of initial blood examination and responses to the treatment for IMHA were compared between the groups. There were significant differences in the number of blood transfusions; once in group with danazol, twice in group without danazol, duration of recovery to normal hematocrit; 7.67±3.08 days in group with danazol, 22.00±5.66 days in group without danazol, and hospitalization; 5.17±0.75 days in group with danazol, 12.75±2.22 days in group without danazol. Therefore, danazol has potential effective on treating IMHA for rapid improvement.

  • 본 연구는 의료기관에 종사하는 의료방사선 작업종사자에게서 직업적 방사선 피폭으로 인한 인체 내 생리적인 변화를 통해 만성적 저선량 방사선피폭의 위험도를 예측하며 현 수준의 변화 상태를 파악하기 위한 목적으로 서울시내 일개 대형병원에서 최근 1~9년간 방사선 작업종사자로 근무한 370명을 대상으로 남녀 간의 체내 혈액성분의 수치변화를 대조군과의 비교 분석을 실시하여 다음과 같은 결론을 얻었다. 1. 종사자의 1~9년간 평균 방사선 누적선량은 남자가 $9.65{\pm}15.2\;mSv$, 여자가 $4.89{\pm}5.55\;mSv$로 남자에서 높았으며 이는 통계적으로도 유의하였다(p<0.01). 2. 남녀 종사자 모두에서 누적선량과 종사기간의 차이에 따른 검사항목들과의 상관성은 매우 미약하였다(r<${\pm}0.25$) 3. 종사기간이 증가할수록 남자에서는 백혈구의 감소자와 증가자, 혈색소의 감소자, 당질의 증가자 비율 유의하게 높았으며(p<0.05), 여자에서도 백혈구의 감소 및 증가자, 호산구의 감소자의 비율이 유의하게 높았다(p<0.01). 4. 누적선량의 증가할수록 남녀모두에서 오히려 이상분포를 보이는 항목은 줄어들었으며, 남자는 림프구와 혈소판의 감소자가 유의하게 높았고(p<0.05) 여자는 림프구와 적혈구의 감소뿐만 아니라 종사기간에서 이상을 보였던 백혈구의 감소 및 증가자 역시 유의한 증가를 나타냈다(p<0.05). 5. 전체적인 변화를 보면 남자 종사자에서는 혈액성분 중 적혈구, 혈소판, 림프구가 주로 감소되며 백혈구는 감소와 증가양상을 같이 보였다. 화학성분 중 당질의 증가가 유의했지만 큰 의미는 없었다. 여자 종사군에서는 남자와 똑같게 백혈구가 감소, 증가 양상을 동시에 보였으며 그밖에 적혈구와 림프구, 호산구의 감소가 유의했다. 이상의 결과를 종합해보면 비록 낮은 선량에 피폭이 되고 있는 의료방사선 종사자일지라도 방사선 피폭에 있어서는 자유롭지 못하여 그 영향으로 인한 체내 생물학적 변화를 겪을 수 있으며 그 변화는 선량에 의존하기 보다는 다분히 확률적일 수 있다는 사실이다. 그러므로 항상 미연에 피폭을 방지하기 위한 노력을 종사자 스스로 기울임을 물론 관련 당국 또한 종사자들의 건강을 체계적으로 관리할 수 있는 시스템을 하루빨리 구축하여 방사선 피폭으로 인한 직업병의 발생의 우려를 없애야 할 것으로 사료된다.

  • To study the effects of anti-cancer, anti-metastasis and immune response improvement of aqua-acupuncture with Cistanches Herba infusion solution, we used Cistanches Herba infusion solution(taken by water-alcohol method) put into Chung-wan(CV12) and Chok-Samni(S36) of BALB/c or C57BL/6 which are corresponding to human body. We observed the cytotoxicity, the effect on the expression of MMP-9 gene, the ability to control cancer cell proliferation, change of body weight, surviving number, MST, ILS, changes in amount of WBC, RBC, PLT, total protein, creatinine, glucose and LDH, weight of spleen, number of pulmonary colony, histological analysis on tissue metastasis of lung and liver, splenic cell proliferation, the expression of cytokine gene, the number of $CD4^+$, $CD8^+$, $CD19^+$ and NK cell, and concluded like this. The results were obtained as follows : 1. The cytotoxicity about B16-F10 cell line of $2^0$, $2^{-1}$, $2^{-2}$, $2^{-5}$ diluent groups in Cistanches Herba infusion solution treatment was inhibited significantly, compared with control group. 2. The cytotoxicity about HT1080 cell line of $2^0$, $2^{-1}$, $2^{-2}$, $2^{-3}$, $2^{-5}$, $2^{-8}$ diluent groups in Cistanches Herba infusion solution treatment was inhibited significantly, compared with control group. 3. The effect on expression of MMP-9 gene was decreased in all the sample groups, compared with control group. 4. The effect on the control-ability on the cancer cell proliferation showed cytotooicity significantly in $2^0$, $2^{-1}$, $2^{-2}$, $2^{-3}$, $2^{-4}$, $2^{-5}$ diluent groups. 5. S-180 cancer cell line transplants in BALB/c mice were inhibited significantly in weight increase in all the sample groups, compared with control group. The surviving number increased in almost sample groups, except one group put into Chok-Samni(S36) with 20% Cistanches Herba infusion solution treatment group that showed same number of the control group. 6. S-180 cancer cell line transplants in BALB/c mice showed high MST and ILS significantly in almost sample groups, compared with control group. But one group put into Chok-Samni(S36) with 20% Cistanches Herba infusion solution treatment group showed low MST and ILS than control group. 7. The sample group injected in vein with B16-F10 cancer cell line in C57BL/6 mice showed increased ILS compared with control group significantly in anti-metastasis test. 8. The sample group injected in vein with B16-F10 cancer cell line in C57BL/6 mice were increased significantly in the number of WBC and glucose, and decreased significantly in the amount of LDH, compared with control group. However, there's no significant increase or decrease in number of RBC, PLT, total protein and creatinine. 9. We couldn't find any significant relation in spleen weight of the sample group. 10. In pulmonary colony, sample group was decreased significantly, compared with control group. 11. Histological analysis of sample group inhivited compared with that of control group in both of lung and liver. 12. In immune system, all the sample groups showed having more relevancy to the effect on splenic cell proliferation than normal group. 13. The effect on cytokine gene expression of all the sample groups were increased than control group. 14. In flow cytometry there's no significant relation in number of $CD8^+$, $CD19^+$ cell, however, the number of $CD4^+$ cell and NK cell in sample groups were increased than in control group. Above the results showed that aqua-acupuncture of Cistanches Herba infusion solution has effects of anti-cancer, anti-metastasis and immune response improvement.
