It is now well established that transient granulocytopenia is common in patients during the initial phase of hemodialysis with new cuprophane membrane, but not with reused nembrane, or some synthetic membranes. In this study, new cuprophane dialyzer was treated with plasma and albumin, respectively, then, peripheral blood leukocytes were counted at the onset and after 15 minute of hemodialysis. In the plasma-treated group, the percent of leukopenia was less (41.3 %) than control group (71.3 %). In the plasmatreated group, the degree of leukopenia was close to that ot'control grou p. The protective factor, therefore is thought to be present in the plasma other than albumin fraction.

We studied the protective effect of Echinacea purpurea against radiation by evaluating changes in the peripheral blood cell count and peripheral blood antioxidant activity. Echinacea purpurea administration had a suppressive effect on radiation-induced leukopenia, especially on lymphocytes and monocytes and resulted in a faster recovery of blood cell counts. Mouse peripheral blood antioxidant activity was increased by Echinacea purpurea, and a relationship between the suppressive effect on radiation-induced leukopenia and the antioxidant effect was suggested.

In order to indentify the effect of Astragali Radix(A.R) on cyclophosphamide(C.Y) induced leukopenia, A.R. extracts(EAR) were treated to mice orally, and blood sampling was done by periods. For the in vivo experiments, mice were divided into 4 groups, which treated EAR before, or after C.Y injection, or both, or none. Rapid normalization in the peripheral blood count of WBC, neutrophils, lymphocytes, RBC, and platelets observed in every EAR treated group regardless of the treatment periods of EAR. These studies suggest that, A.R. premedication can be effective in protection of bone marrow suppression during anticancer therapy.

The immunomodulatory effect of a new herbal preparation, HemoHIM, on the recovery from leukopenia induced by cyclophosphamide treatment was investigated. The HemoHIM was made up with an addition of the ethanol-insoluble fraction to the total water extract of Angelica Radix, Cnidii Rhizoma and Paeonia Radix. Daily oral administration of 100 mg/kg BW or 500 mg/kg BW HemoHIM accelerated the recovery from cyclophosphamide-induced leukopenia. HemoHIM increased the number of leukocytes and lymphocytes in the peripheral blood when compared with the cyclophosphamide-treated control. Moreover, the suppressed natural killer (NK) cell activity and interferon $(IFN)-{\gamma}$ secretion in the cyclophosphamide-treated mice were restored by the administration of HemoHIM. HemoHIM significantly reduced the abnormally heightened ratio of interleukin $(IL)-4/IFN-{\gamma}$ and immunoglobulin (Ig)E/IgG2a in the cyclophosphamide-treated mice. These results suggest that HemoHIM accelerates the recovery from leukopenia and alleviates the imbalanced T helper (Th)l/Th2 responses in the cyclophosphamide-treated mice. Additionally, HemoHIM was found to stimulate normal splenocytes to secrete not only Thl type cytokines such as $IFN-{\gamma}$ and IL-2, but also Th2 type cytokine IL-4. In conclusion, our results show that HemoHIM certainly has an influence on the balanced recovery of immune cells and the activation of their activities in the cyclophosphamide-treated mice.

양돈산업에 있어 돼지 써코바이러스 2형(PCV2)의 복합감염으로 인한 이유자돈의 질병 피해가 막대하다. PCV2 감염에 대한 숙주의 민감도는 상이한 것으로 알려져 있으며, 따라서 숙주의 민감도를 구분하는 것은, 이를 이용한 숙주의 저항성 향상 연구에 필수이다. 본 연구의 목적은 이유자돈군의 혈액 내에서 PCV2 바이러스에 대한 숙주의 민감도를 구분 짓고 구명하는데 있었다. 본 연구에서는 자연적으로 바이러스에 감염된 10주령의 이유자돈군으로부터 혈청을 채취하여 PCV2 바이러스량과 항체가를 측정하고 혈구분석을 실시했다. 또한, 측정된 PCV2 바이러스량과 항체가를 기준으로 자돈군 내에서 저항성군과 민감성군을 선정하였고, 통계분석결과 저항성군에 비해 민감성군에서 백혈구 수가 현저히 줄어든 것을 확인하였다. 본 연구를 통해서 PCV2 감염에 대한 돼지의 민감도를 구분짓기 위한 PCV2 바이러스량과 항체가를 이용한 복합기준을 제시할 수 있었으며, 이유자돈군의 PCV2 관련 질병저항성 및 백혈구감소증을 확인할 수 있는 방법을 마련하였다.

Enterotoxemia caused by Clostridium perfringens(Cl. perfringens)has occurred sporadically with devastating effect in Korean cattle. The disease is confirmed by detecting bacterial toxin the interstinal contents. however diagnosis has been challenging since the toxin is short lived and it must be demonstrated within one hour following death. The purpose of this paper is to provide additional clinicall and pathological information derived from observation of cattle administered with Cl. perfringens type A and/or its toxins isolated from natural case. Clinically cattle died suddenly in lateral recumbency with dyspnea tachycardia and muscle tremor without increased rectal temperature. hematology showed leukopenia with absolute decrease of all leukocytes. Blood glucose AST and ALT were increased. Grossly lungs were hyperemic haemorrhagic and edematous. Small intestine especially ileum was hyperemic and hemorrhagic with diffuse areas of necrosis. This study demonstrated that death without increased rectal temperature combined with leukopenia increased serum glucose pulmonary haemorrhage and edema plus necrotizing ileitis are important features associated with enterotoxemia due to Cl. perfringens type. A.

The fruiting body of Ganoderma lucidum (Polyporaceae) is one of the valuable crude drugs, which has been used clinically in Korea, China, and Japan for a long time as a tonic and sedative, and for the treatment of hepatopathy, chronic hepatitis, nephritis, gastric ulcer, hypertension, arthritis, neurasthenia, insomnia, asthma, and poisoning and chronic bronchitis. Nowadays, this mushroom is used for leukopenia and paid much attention as a home remedy. (omitted)

Cerebellar atrophy was found that a patient was taking oral phenytoin for 3 years. 53 years old female patient with General tonic clonic(GTC) type seizure was prescribed phenytoin. In the process, she developed ataxic gate, dysarthria. Brain magnetic resonance imaging(MRI) finding was revealed differential diagnosis cerebellar atrophy. She was prescribed epileptol instead of phenytoin. But leukopenia, thrombocytopenia occurred. As a result, phenytoin restarted. Development of medical state decreased abuse of anticonvulsants. Considering various convulsive disorders, we must give attention to using anticonvulsants.

A protein-polysaccharide fraction was isolated from the mycelial culture of a Korean basidiomycetous fungus, Hebeloma crustuliniforme, and was named HCA (Hebeloma crustulineforme fraction A). When intraperitoneally injected at 200 mg/kg/day once daily for 10 days, HCA inhibited the growth of sarcoma 180 solid tumor in ICR mice by 65.1% (p＜0.05). HCA also exerted protective effect against leukopenia induced by cyclophosphamide with the protection ratio of 39.7% (p＜0.01).
