Patients undergoing maintenance hemodialysis(HD) potentially have an increased risk of exposure to viral hepatitis. The reported prevalence of antiHCV in hemodialysis patients varied widely form 7.6-54% according to dialysis center and there were there were many reports that showed the correlation between the prevalence of antiHCV and duration of HD or transfusion amount. Fifty-four patients on regular hemodialysis at our hospital were evaluated for the presence of hepatitic C antibody(antiHCV) with the comparison of various parameters such as duration of HD, amount of transfusion, past history of hepatitis, serologic markers of hepatitis B and current liver function. AntiHCV using second-generation enzyme linked immunosorbant assay were found in six of 54HD patients(11.1%). Among six antiHCV(+) percent four patients were found to have HCV-RNA in their plasma detected by PCR. The percent of male patients were significantly higher in antiHCV(+) group(66.7 vs 31.3%, p<0.05). The positivity of antiHCV did not correlated with the duration of HD and amount of transfusion(p>0.05), but prevalence increased over 2 years ( 5.9% in 1991, 11.1% in 1993) and HBsAg prevalence remained unchanged(9.8% in 1991, 9.3% in 1993). Therefore, regular follow-up of liver function test and use of separate machine for antiHCV positive patients may be needed to prevent the transmission of the hepatitis C virus during the hemodialysis process itself.

N/A Objectives: Nutritional factors play a role in the morbidity and mortality of patients in maintenance hemodialysis as well as in their quality of life and ultimate rehabilitative potential. It was reported that if the deviation of urea distribution volume calculated by Urea Kinetic Modeling(UKM) (Vol-Dev) from Anthropometric volume exceeded the acceptable range, clinical application of the NPCR (normalized protein catabolic rate) as nutritional index might be inappropriate. And it was also reported that if the KT/Vurea without consideration of residual renal function (D-KT/V) was above 1.5 or below 0.8, the NPCR might be inaccurate. So we selected patients whose Vol-Dev was within the acceptable range and grouped according to the D-KT/V. Then we analyzed the relationship between the NPCR and other nutritional parameters. Methods: We selected 17patients undergoing maintenance hemodialysis with adequate Vol-Dev level and grouped as group 1 if D-KT/V was between 0.8 and 1. 5, as group 2 if D-KT/V was below 0.8 or over l.5, We measured the mean level of albumin, calcium, phosphorus and hematocrit and calculated midarm muscle area (MAMA), midarm fat area (MAFA) as anthropometric measurements. Results: 1) Nutritional Index: There were no differences in serum albumin, calcium, phosphorus and hematocrit between two groups. The mean MAMA of group 1 (37.4cm2) was not different from that of group 2(27.9cm2), but mean MAFA of group 1(19.2cm2) was significantly higher than that of group 2(14.3cm2). The NPCR of group 1 (1.00) was not different from that of group 2(1.12). 2) UKM Parameter: The mean level of D-KT/V as single dialysis dose in group 1 (1.23) was significantly lower than that of group 2(1.69) and the mean level of TW-KT/V as weekly dialysis dose in Group 1 (3.17) was significantly lower than that of Group 2(4.05). The mean level of TWR-KT/V as weekly dialysis dose with consideration of residual renal function in Group 1(3.24) was significantly lower than that of Group 2(4.07) also. 3) Correlation between NFCR and dialysis dose: There was no correlation between D-KT/V and NPCR in both Group. In group 1, there was positive correlation between NPCR and TW-KT/V or TWR-KT/V. But in group 2, there was no correlation between NPCR and TW-KT/V or TWR-KT/U. 4) Correlation between NPCR and Nutritional Index: There was no correlation between NPCR and serum nutritional index (albumin, calcium, phosphorus, hematocrit). There was also no correlation between NPCR and anthropometric parameter (MAMA, MAFA). Conclusions: It is not likely that the NPCR reflects the protein catabolic rate accurately in case of D-KT/V exceeded adequate level (0.8≤, ≤1.5). Although the protein catabolic rate might be increased due to the effect of dialysis itself, there was no significant change in the nutritional status of patients. Even though the D-KT/V was within the adequate level, it is difficult to evaluate the patients nutritional status with NPCR only.

The noticeable results in this study were that 12-week ginseng administration effected the mean heart rate and lactate accumulation during submaximal exercise . This result suggests that ginseng may more contribute to the alleviation of metabolic acidosis in submaximal exercise than in short- strenuous anaerobic exercise and the alleviative action may be achieved by the increment of feul storage in muscle and liver through the improvement of insulin secretion ability rather than through the response of HPA axis hormones or metabolic role of serum CPK.

운동과 인삼의 뇌하수체-부신피질 축 호르몬의 활성화 작용
위승두,정일규 조선대학교 스포츠과학연구소 1991 스포츠科學硏究 Vol.4 No.-
인삼의 항 스트레스 작용기전은 HPA axis의 활성화를 통해 이루어 진다고 설명되고 있으며, 장기간의 운동 역시 HPA axis에 대한 반복적인 자극에 의해 부신비대 등 적응성 변화를 일으킨다고 보고되고 있다. 그러므로 인삼이 일종의 스트레서(stressor)로서 작용하는 운동에 의해 활성화되는 HPA axis 반응을 더욱 항진시킴으로써 인체에 가해지는 스트레스에 보다 효과적으로 대처하게 해준다는 개념이 성립될 수 있을 것이다. 그러나 이러한 개념의 검증에는 선결해야 할 몇가지 논점이 따르게 된다. 그것은 첫째, 운동훈련에 따른 특정부하강도에서의 HPA axis 호르몬 반응의 변화가 있는가? 둘째, 이들호르몬의 반응이 변화된다면 그것은 운동스트레스자체의 크기 변화에 따른 것인가? 아니면 그 스트레스에 대한 HPA axis 민감도의 변화에 의한 것인가? 셋째, 인삼 투여에 따른 HPA axis 활성화 작용은 운동스트레스 상황하에서도 마찬가지의 약리적 효과를 발휘하는가? 넷째, 인삼이 운동시 HPA axis 반응을 항진시킨다면, 그러한 항진된 반응은 수행력과 관련하여 어떠한 의미를 갖고 있는가? 이러한 논점에 대한 추후 많은 실험적 증거에 의해서 인삼의 항스트레스 작용 및 ergogenic aid로서의 가능성이 평가되기를 기대한다. The purpose of this article was to review and discuss the effect of HPA axis activation of ginseng related to exercise. Ginseng saponine has been reported to activate the HPA axis as well as exercise. Therefore, the concept can be estabilished that HPA axis activation effect of ginseng, probably, help athletes to improve their performance through an adaptation to exercise stress. But, there are some questions to be resolved in order to prove that concept. First, Can exercise training chang the response of HPA axis on the given relative load? Second, If the response were changed, is the change of response due to change of exercise stress itself, or the sensitivity of HPA axis to the stress? Third, Can ginseng administration take effect of HPA axis activation in exercise situation as well as rest? Last, What is the significance of HPA activation effect of ginseng in relation with performance? We hope that the anti-stress effect and posibility as an ergogenic aid of ginseng be evaluated by the future experimental study on this topic.
