Sodium arsenate and Paljin-Tang extract (PJT), a herbal restorative were treated p.o. 20 mg/kg and 500 mg/kg, respectively, and concurrently to rats, and examined the biochemical parameters in blood. The values of white blood cell (WBC), red blood cell (RBC), hemoglobin (Hgb) and hematocrit (Hct) in each group did not show significant variance. The value of aspartate aminotrasferase(AST) of arsenic-treated group was increased for 2 weeks significantly while that of the group of concurrent administration with PJT became low significantly compared with arsenic-treated group and the value of alkaline phosphatase (ALP) of arsenic-treated group was decreased while that of the group of concurrent administration with PJT was increased significantly compared with arsenic-treated group. The value of glucose (Glu) was increased and those of lactic dehydrogenase (LDH), blood urea nitrogen (BUN) and triglyceride (TG) were decreased at first but increased later while the group of concurrent administration with PJT showed significant recovery from the toxicity of arsenic.

Many researchers have paid attention to the studies on the interaction between non-thermal plasma and aqueous solutions for biomedical applications. The gas composition in the plasma is very important. Oxygen and nitrogen are the main gases of interest in biological applications. Especially, we focus on the oxygen concentration. In this experiment, we studied the role of oxygen concentration in plasma induced chemical reactions in solution. At first, the amount of ions are measured according to changing the oxygen concentration. And we checked the relationship between these ions and pH value. Secondly, when the oxygen concentration is changed, it identified the type and amount of radical generated by the plasma. In order to confirm the effect of these chemical property change to biological material, hemoglobin and RBCs are chosen. RBCs are one of the common basic biological cells. Thirdly, when plasma treated according to oxygen concentration in nitrogen feeding gas, oxidation of hemoglobin and RBC is checked. Finally, membrane oxidation of RBC is measured to examine the relation between hemoglobin oxidation and membrane damage through relative hemolysis and Young's modulus. Our results suggest that reactive species generated by the plasma differsdepending on the oxygen concentration changes. The pH values are decreased when oxygen concentration increased. OH decrease and NO increase are also observed. These reactive species makes change of chemical properties of solution. We also able to confirm that the difference in these reactive species to affect the oxidation of the Hb and RBCs. The Hb and RBCs are more oxidized with the high oxygen concentration conditions. But membrane is damaged more by plasma treatment with only nitrogen gas. It is shown that red blood cells membrane damage and oxidation of hemoglobin are not directly related.

Hematotoxicity and vascular irritation of DA-125, a new anthracycline antitumor antibiotic, were investigated in mice and rabbits. In hematotoxicity study, healthy male ICR mice were treated with DA-125 by a single intravenous injection at doses of 18 and 24 mg/kg. After 4, 8, 12 and 16 days WBC count, RBC count, hemoglobin concentration, hematocrit value, and platelet counts were measured respectively. As a positive control, 12 mg/kg of doxorubicin (DXR) was used in the same manner. Remakable reductions of WBC counts in groups treated with DA-125 or DXR were observed 4 days after administration and returned to normal range 8 days after injection in groups of DA-125 18 mg/kg and DXR 12 mg/kg. The recovery of leukopenia induced in a group of DA-125 24 mg/kg took about 16 days after administration. The RBC counts, hemoglobin concentrations and hematocrit values also decreased in all drug treated groups on day 8 and recovered thereafter. The platelet counts of groups treated with DA-125 or DXR decreased on day 4 and recovered from day 8 of experiment. Local vascular irritation of DA-125 was also assessed in rabbits. The obtained results can be summarized as follows. 1. Thrombophlebitis was not induced even after daily intravenous administration of 0.4% solution of DA-125 or 0.2% solution of DXR for 7 days. 2. Macro- and microscopic observations revealed that the irritative activity of 0.4% solution of DA-125 in blood vessels was not so much different from that of saline when they were injected once a day into vein retroauricularis of rabbits for 7 days. 3. Mild inflammatory reaction was noted around vessels in rabbits treated with 0.2% solution of DXR after consecutive intravenous infusion for more than 5 days. 4. The potencies of vascular irritation of the test solutions were summarized in the following order; saline = 0.4% DA-125<0.2% DXR. These results indicated that DA-125 showed similar pattern of hematotoxicity with DXR but was less hematotoxic than DXR, and that 0.4% solution of DA-125 did not elicit unusual toxic properties when injected through intravenous route for clinical practice.

A dog which was hospitalized to Veterinary Teaching Hospital, College of Veterinary Medicine, Jeonbug National University on December 28, 1988 was revealed severe anemia: hemoglobinuria and weakness. In the inspections, abdominal pain and spleno megaly at the ventral abdomen were detected by palpations. In the examinations of blood, the obtained results were summarized as follows: Babesla spp. was identified on the blood smear stained with Giemsa. The Babesia spp. was assumed to the Babesia gibsoni for the their small size and pleomorphism such as comma form, ring form and dot form. In the blood examinations of the patient, Ht: 22.5％, RBC:354${\times}$10$^4$/${\mu}\ell$, Hb: 8.8g/dl, serum protein: 8g/dl, and WBC count was 21, 425/${\mu}\ell$. In the chemical examinations of serum, the value of AST(GOT) was 30iu and ALT(GPT) was 20iu, respectively. The blood sugar was 60mg/d1. In the urine test, urine protein was 30mg/d1 and the hemoglobin In the urine was the ＋＋＋ and occult blood reaction(Benzidine test) in the feces was ＋＋＋. Splenomegaly was confirmed by X-ray examination. To confirm for the Babesia spp. infection, 5ml of the whole blood of the patient(3％ of Parasitized erythrocytes) were inoculated into the cephalic vein of the two normal dogs. In the blood of experimental dogs which were inoculated parasitized blood, Babesia spp. was detected in the two doss and pleomorphic parasites were observed, too. In the blood examinations of No. 1 the Ht and RBC were decreased to 6.8％ and 52${\times}$10$^4$/${\mu}\ell$, respectively. WBC count was 10.600/${\mu}\ell$ and serum protein was 6.8g/dl. The rates of parasitized erythrocytes were 15％ in the experimental dog. Also ＋＋＋ of the hemoglobin was detected in the urine. In the X-ray examination, splenomegaly was comfirmed and it was confirmed by autopsy of the experimental dog(No. 1).

From December of 1994 to April of 1995, we, SHUH Department of Pediatric Thoracic and Cardiovascular Surgery, studied effects of aprotinin. 95 patients were randomly divided into two groups : group I (n=47) with aprotinin and group ll (n=48) without aprotinin. Aprotinin was given as one shot injection to cardiopulmonary bypass perfusion solution with dose of 50,000 KIUikg. Laboratory data such as hemoglobin, hematocrit, BUH, creatinine, fibrinogen, electrolyte concentration, aPTT, PT, and AT R was checked preoperatively, 5 minutes after anesthesia, 5 minutes and 35 minutes after CPB circulation, and 5 minutes, 3 hours, and 24 hours after reperfusion. Also, chest-tube drainage, transfused amount of RBC, platelet concentrate, and fresh frozen plasma within first 24 hours postoperatively were checked and analyzed after transition nn body weight demension. Only RBC transfused postoperatively had statistical significance with P value of less than 0.001. Others had no difference statistical wise. Postoperative side effects of aprotinin was not detected weeks after the surgery and there was no reoperated patient due to postoperative bleeding.

Effects of repeated administration of diminazene aceturate (Hoechst Veterin r GmbH. Ger- many) that has been introduced as effective compound against Babesiosis and trppanosomiasis were investigated in dogs experimentally infacted with Babesia gibsoni. Adull mongrel dogs of both sexes were inoculated will nonpreserved infected blood and then maintained chronic anemia. A single dose of diminazene aceturate of 7mg/kg b.w. was administrated intramnuscularIy on day 7.1 arid ,7. Clin- ical and hcmatological findings following inoculation and medication were observed and 7enlm bio chemical analysis also was monitored. Parasitemia was detected between 3 and 6 days after inoculation. The rate of parasitized erythrocytes,1 in peripheral blood reached the peak on the 13th day and was maintained the percentage of 0.1 to 1.0 until the medication of diminazene aceturate. RBC was significantly (p<0.01) decreased on the 3rd day and then kept on decreasing. The lowest value was observed on the 16th day. WBC remained generally within normal ranges. PCV revea1ed the sig-nificant (p<0.01) decrease within the range of 24-27% and platelet was significantly (p<0.05) decreased during the period. Senum chemical values (ALT, AST. total bilirubin. LDH BUN, area- tinine, total protein. albumin and glucose) were within normal ranges during the experimental period. Serum CPK values were significantly (p<0.01) increased on the 3rd day. There was no clinically, sig-nificant difference in a single dose of diminazene aceturate of 7 mg/kg b.w. But the administration of diminazene aceturate of 14 mg/kg b.w. revealed vomiting and anorexia and one dog died in 30 hours after administration. The administration of 14mg/kg b.w. resulted in vomiting, salivation, actor- exia, tremor of head and involuntary movement and one dog died in 27 hours after administration. WBC, RBC, PCV and Platelet values were no significant difference and hematological findings revealed persistent anemia and thrombocytopenia during chronic anemia after inoculation. AST activity its was significantly (p<0.01) increased 11\\`from 3 days after medication and AST activity was on the same trend. Serum CPK activity revealed significant (p<0.01) increase within 6 hors)\\`s after every administration and decreased in 48 howl·s after administration.

To develop a natural antioxidant and anti-hemolytic agents, we investigated the effects of ethanol extracts of Rubus coreanus Miquel (crude extracts). Crude extract was extracted with ethanol. Antioxidant activity of crude extracts was evaluated by employing two different assays, 1,1-diphenyl-2-picryl hydrazyl (DPPH) radical scavenging activity and super oxide dismutase(SOD)-like activity. Also, anti-hemolytic activity of crude extract was determined using $H_2O_2$-induced hemolysis in normal rat red blood cells (RBC) or plasma. The extracts obtained from crude extract dose-dependently increased the scavenging activity on DPPH-induced radicals and SOD-like activity. RBC oxidative hemolysis induced by $H_2O_2$ was significantly suppressed by the extracts of Rubus coreanus Miquel in a dose-dependent manner. These results suggest that crude extracts may have value as the potential antioxidant and anti-hemolytic medicinal plant.

The concern of the antioxidant micronutrient status in normal healthy people, including antioxidant trace minerals such as Cu, Zn, Mn, Fe and Se is focused since systemic oxidation is involved in various chronic diseases. In the present study, we evaluated the concentration of trace minerals (Cu, Zn, Mn, and Fe) which are considered as potential antioxidant minerals in plasma, red blood cells (RBCs) and urine in normal healthy Korean subjects. The 760 subjects (male 341, female 419; mean age 54.2 $\pm$ 18.9) were recruited from the rural, urban and metropolitan city in South Korea. Dietary intake was evaluated using 24-hours recall for general major nutrient intake assessment. The trace elements (Cu, Zn, Mn, and Fe) concentrations in plasma, RBCs, and urine were measured by inductively coupled plasma spectrophotometer (ICP) and atomic absorption spectrophotometer (AAS). Cu and Zn levels in plasma, RBCs and urine in normal healthy South Koreans were within the normal range of those mineral levels, but Mn and Fe levels were higher compared to the normal range of those mineral levels. None of the selected trace mineral levels in plasma and RBC's was lower than the normal range value. The results showed that Zn and Cu levels in plasma and RBC's in Korean were within the normal range, and plasma and urinary Mn and Fe levels were higher than the normal reference values. Potential antioxidant trace mineral (Cu, Mn, Zn and Fe) levels in Koreans are within or a bit higher than the normal range.

This experiment was carried out to study the preventive effect of cysteine on the toxicities of captafol to the hematological and serum biochemical values. A single dose of captafol(5mg/kg BW, ip) was given to male Sprague-Dawley rats and its toxicities were evalutated by body weitht changes, autopsy findings, absolute organ weight, and hematological and serum biochemical parameters. The single dose of captafol caused significant decreases in body weitht, and absolute liver weight, as-cites, fibrin clot in abdominal cavity, adhesion of liver lobes significant elevation of number of RBC, hemoglobin concentration and serum AST activity, and decreased of serum phospholipid level. Where as cysteine(over 58mg/kg BW) given immediately after captafol appeared to prevent the ascites, fibrin clot in abdominal cavity and liver lobe adhesion. It also prevented the liver and blood, especially RBC toxicites. The results suggest that cysteine and other compounds containing sulfhydryl groups may protect the subjects from captafol-induced toxicity.

The aim of this study was to elucidate the mechanism of anemia associated with Dangguibohyel-tang (DBT) in rats. Using cyclophosphamide-induced (30mg/kg BW) anemic rats, changes in weight gain, the levels of red blood cell (RBC), hematocrit (Hct), platelet and hemoglobin (Hgb), serum vitamin B12, ALT(GPT) levels and erythropoietin (EPO) gene expression were monitored, and compared with DBT (1,000mg/kg BW, 14d)-treated and EPO (1,000IU/kg BW, 14d, s.c.)-treated rats. Food efficiency ratio (FER) were 31.6%, in normal group, 28.1% in cyclophosphamide-induced control group, 31.7% in DBT-treated group and 25.1%, in EPO-treated group after 14 days. The levels of red blood cell (RBC), hematocrit (Hct), platelet and hemoglobin (Hgb) of DBT-treated group were significantly higher than those of control. And DBT extract administered group showed dominant effects on the recovery of Hgb level. Serum vitamin B12 and ALT(GPT) levels were significantly increased at DBT-treated groups. EPO gene expression was decreased 91,9% in control group, 79.6% in DBT-treated group and 53.9% in EPO-treated group, respectively. These results suggest that administration of DBT could prevent human patient from chemotherapy derived anemia by improving hematological value and EPO status.
