1991년 1월부터 1993년 2월까지 영남대학교 의과대학 부속병원에서 출생하여 신생아 중환자실에서 치료 받았던 12명의 미숙아를 대상으로 무작위로 대조군과 rHuEPO투여군으로 나누어 체중 kg당 100unit의 rHuEPO을 1주간 3회씩 4주동안 피하주사하고 rHuEPO투여 시작과 같이 체중 kg당 3mg의 elemental iron을 매일 경구투여 하였고 출생 후 수유가 가능할 때 부터 25unit씩의 비타민 E를 매일 경구투여 하였다. 망상적혈구, 혈색소치, 백혈구수, 혈소판수, 혈청 철, ferritin, 총 철결합능, erythropoietin농도, 활력징후, 체중, 간기능, 신장기능 및 피하주사부 위의 국소 부작용을 비교해 본 결과 치료 시작전 erythropoietin의 농도는 대조군과 rHuEPO투여군 사이에 차이는 없었으며 모두 정상 범위에 속했고 rHuEPO투여군에서는 치료 1주에서 3주사이에 급격한 망상적혈구의 경향이 관찰되었고 전반적으로 혈색소치, 백혈구수, 혈소판수, 혈청 철, ferritin, TIBC등에서는 차이가 없었다. 그리고 체중증가 및 활력증상, 간기능, 신장기능에서도 대조군과 rHuEPO투여군 사이에서 차이가 없었고 rHuEPO 투여 기간 동안 계속 정상적으로 유지되었다. 결론적으로 우리의 연구에서는 rHuEPO치료로 뚜렷한 혈색소치 및 헤마토크리의 증가를 볼 수 없었지만 망상적혈구가 치료 초기에 증가되는 경향이 관찰되었고 치료로 인한 특이할 만한 부작용이 없었으므로 첫째, 치료 기간 중의 예견할 수 없이 발생하는 패혈증, 무시할 수 없는 채혈량과 spontaneous endogenous erythropoietin생산이 rHuEPO의 반응에 미치는 영향, 둘째. rHuEPO의 가장 높은 효과를 얻기 위한 보다 적절한 투여용량, 기간 및 rHuEPO의 투여를 출생 후부터 바로 예방 목적으로 할 것인지 또는 출생 몇 주 후부터 rescue therapy로 할 것인지 투여 시작 시기, 셋째, 용량의 증가 및 감소에 동반되는 부작용의 정도등을 고려해서 앞으로 더 많은 미숙아를 대상으로 지속적인 연구를 한다면 rHuEPO을 이용해 더욱 더 활발하고 효과적으로 미숙아 빈혈을 치료할 수 있으리라 기대한다.

The ethanol extract of peony root (Paeonia Lactiflora Pall, Paeoniaceae) and its major active components including gallic acid and methyl gallate were evaluated for their protective effects against free radical generation and lipid peroxidation. And protective effects against hydrogen peroxide-induced oxidative DNA damage in a mammalian cell line were performed. The ethanol extract of peony root (PRE), gallic acid and methyl gallate were shown to possess the significant free radical scavenging effect against 1,1-diphenyl-2-picryl hydrazine (DPPH) radical generation and were revealed the inhibitory effect of lipid peroxidation as expressed by malondialdehyde (MDA) formation. They were also found to strongly inhibit hydrogen peroxide-induced DNA damage from NIH/3T3 fibroblasts, assessed by single cell gel electrophoresis. Furthermore, oral administration of 50% PRE (50% ethanol extract), gallic acid and methyl gallate potently inhibited micronucleated reticulocyte (MNRET) formation of mouse peripheral blood induced by KBrO3 treatment in vivo. Therefore, PRE containing gallic acid and methyl gallate may be a useful natural antioxidant by scavenging free radicals, inhibition of lipid peroxidation and protecting oxidative DNA damage.

The aim of this study was to evaluate the in vivo effect of galangin and the 70% ethanolic extract of Alpinia officinarum (AO) toward $KBrO_3$-induced DNA and chromosomal damage in mice. Galangin and AO inhibited the formation of 8-hydroxy-2'-deoxyguanosine (8-OH2'dG) as an indicator of DNA oxidative damage in the liver cell. Galangin and AO showed the inhibitory effect on the formation of DNA single strand break in the splenocyte by single cell gel electrophoresis (SCGE) assay and also inhibited micronucleated reticulocyte (MNRET) formation of peripheral blood in tail blood of mice. Vit-E revealed antigenotoxic effects in DNA and chromosome levels, but galangin was more potent active compound compare to vit-E under our experimental conditions. The results suggest that the extract of Alpinia officinarum containing galangin can modify the oxidative DNA and chromosomal damage and may act as chemopreventive agent against oxidative stress in vivo.

We have developed the tablet formulation of Triticum aestivum (wheatgrass) and investigated clinically, its effects in patients suffering from b-thalassemia (major) at K. T. Children Hospital, Civil Hospital, Rajkot. The tablets (wheatgrass powder 250 mg.) were given 3 times in a day for 9 months. Blood samples were collected at the start, after 6 months and 9 months and analyzed for various biochemical and hematological parameters. Treatment with wheatgrass formulation for 9 months produced significant decrease in hemoglobin, total RBC, eosinophil and reticulocyte counts. The mean corpuscular volume (MCV) and mean corpuscular hemoglobin concentration (MCHC) were significantly increased was significantly increased. The serum ferritin was also significantly decreased. There was no influence on serum magnesium, serum iron and Thiobarbituric acid reacting substances (TBARS). Our data indicate that treatment with wheatgrass on patients with $\beta$-thalassemia (major) may have beneficial effects in the form of a decrease in ineffective erythropoiesis, stimulation of hemoglobin synthesis in RBC, decrease in iron load and decrease in eosinophil count.

Erythropoietic activity in anemic Plasma of chronic posthemorrhagic anemic men was studied in rats after subcutaneous injection of anemic plasma. Anemic plasma was obtained from blood donors who sold their blood once or twice a week for one or two years to blood bank. Hemoglobin concentrations of 8 blood donors ranged between 4.6 and 8.4 gm/100 ml. Pooled plasma was treated by acidification-boiling method and adjusted to pH 7.5 by adding 0.1 N NaOH. 7ml/kg and 15ml/kg of anemic plasma filtrate was injected to 2 groups of rats respectively for 7 and 8 days. Hemoglobin concentrations, red blood cell counts and reticulocyte counts were observed before and after injection of anemic plasma and no change was induced by the injection. Subsequently, it was concluded that there was no erythropoietin of high titer in the plasma of chronic post-hemorrhagic anemic men.

The blood samples of 280 suckling pigs and of 300 adult pigs were studied in a hope to establish normal hemograms of swine as reared in Korean local conditions. The examination included total counts of erythrocytes, leukocytes differential count, hemoglobinometry, and reticulocyte count. The results of this study are summarized as following. 1. Higher erythrocyte count was observed in adult pigs as compared with the values reported by other workers. The normal erythrocyte value for malewas $8.4{\pm}0.9$ millions with approximately 0.6 million less for female. 2. Relatively higher hemoglobin concentration was measured in the piglets at birth, which slightly decreased in piglets of 2nd and 3rd weeks. The Hb concentration was highest in piglets of 5th week amounting to 15.8gm/100ml of blood, and it gradually decreased to the adult-level thereafter. 3. The average diameter of erythrocyte was $6.6{\pm}0.72{\mu}$ in suckling pigs and $6.3{\pm}0.11{\mu}$ in adult pigs. This shows that erythrocytes of piglets are larger than those of adult pigs and the mean diameter is also arger than reported by other investigators. 4. The lower mean percentages of eosinopils, basophils, monocytes were found both in the blood of suckling and adult pigs. 5. The other blood values were in general agreements with the values reported by other workers.

The ethanol extracts of the mixed vegetables (Bioactive Vegetables, BV) and the mixed fruits (Bioactive Fruits, BF) were evaluated for their in vivo antioxidant activities. Four weeks treatment of oral administration was performed to mice. A $KBrO_3$ as a potent oxidant was used to induce the oxidative stress for in vivo experiment. BV and BF were shown to possess the significant inhibitory effect of lipid peroxidation as measured by the level of malondialdehyde (MDA) formation although the potencies were not higher than those of well-known antioxidants such as vitamin C, trolox and quercetin. Furthermore, BV and BF inhibited DNA damage assessed by single cell gel electrophoresis (comet assay) and reduced the micronucleated reticulocyte (MNRET) formation of peripheral blood. Antioxidants tested also revealed potent inhibitory activities higher than BV and BF. These antigenotoxic activity profiles were similar to that of abovementioned inhibition of lipid peroxidation. Therefore, BV and BF having mild antioxidant activity as functional food candidates may be useful natural antioxidants by the inhibiting of lipid peroxidation and the protecting oxidative DNA and chromosomal damage.

An antiviral protein (CAP30) with ribosome-inactivating activity was purified from the leaves of Chenopodium album L. through ammonium sulfate precipitation and column chromatography using S-Sepharose, Blue-Sepharose, FPLC Suprose12 HR, and FPLC Mono-S. The molecular wight of CAP30 was estimated to be 30kD. CAP30 was thermostable, maintaing its activity even after incubation at $70^{\circ}C$ for 30 min, and was stable in the pH range of 6 to 9. In a cell-free in vitro translation system using rabbit reticulocyte lysate, protein synthesis was inhibited by the addition of CAP30 with an $IC_{50}$ of 2.26pM. The comparison of N-terminal amino acid sequences of this protein with known ribosome-inactivating proteins (RIPs) revealed that it had some sequence homology with PAP-S and PAP-R from pokeweed (Phytolacca americana)and dodecandrin from P. dodecandra, but had no sequence homology with RIPs from other plants belonging to different orders. The mosaic symptoms on tobacco leaves caused by cucumber mosaic virus infection was completely inhibited by 100 ng/ml of the pure CAP30 protein.
