It was well known that B. pertussis cells possess protective antigen, histamine sensitizing factor, heatstable and labile toxin, hemagglutinin, agglutinogen and the others. Previous reports involving above antigenic properties of B. pertussis have been carried out for several years. However, leucocyte promoting property was not yet investigated. In this report, the results of studies on the leucocytosis, particulary the lymphocytosis, produced in mice by injecting pertussis vaccine were presented. Especially leucocyte promoting property and histamine sensitizing property of B. pertussis vaccine treated at various temperatures were compared. The relationship between the leucocyte promoting property and histamine sensitizing property was investigated. Results were as follows. 1. Although leucocytosis was significantly rised in both 0.5ml injection and 0.1ml injection of pertussis vaccine than in control, at the higher dose (0.5ml injection) an elevation in white cell count was more significant. The leucocyte responce to pertussis vaccine was greater following 0.5 ml injection than following 0.1ml injection. 2. Lymphocytosis was significantly rised in both 0.5ml injection and 0.1ml injection of pertussis vaccine than in control. At higher dose (0.5ml injection), an elevation in lymphocyte count was more significant. 3. Order of elevation in differential leucocyte counts was lymphocyte, polymorphonuclear leucocyte and monocyte. 4. The leucocyte response to pertussis vaccine was 2 fold greater following intravenous injection than following subcutaneous injection. 5. Decrease leucocyte promoting activity and histamine sensitizing activity resulted from exposure to temperature above $56^{\circ}C$. Histamine sensitizing activity of pertussis vaccine treated at various temperatures paralleled leucocyte promoting activity.

Primary subacute pyogenic osteomyelitis, or Brodie's abscess has received much attention since its initial documentation in the literature in 1832 by Sir Benjamin Brodie. Brodie's abscess is a localized form of chronic osteomyelitis that occurs most often in the metaphyseal area of the long bones of the lower extremities of young adults, Intermittent pain of long duration is the presenting complaint, along with local tenderness over the affected area. Laboratory evaluation is unrevealing, with a normal white blood cell count and differential count. The erythrocyte sedimentation rate may also be normal. Roentgenogram shows a markedly varied appearance and an abscess may be easily mistaken for various neoplasm. The most common organism cultured from abscess is Staphylococcus species. Treatment includes curettage of the lesion and administration of antibiotics. We present a case report (with a 1-year follow-up period), demonstrating the successful surgical treatment of Brodie's abscess of the distal metaphysis of the left tibia caused by Salmonella cholerasuis in a 33-year-0ld male who had no hemoglobinopathy.

As an antitumor agents cyclophosphamide (CPA) is frequently used in animal clinic. Important adverse effects of its administration are leukopenia, thrombocytopenia and anemia. We investigated the effects of chicken egg white derivatives (EWD and EF-203) on the changes of blood cells and the neutrophil phagocytosis of rats administered with CPA. Rats were administered CPA peritoneally at dose of 50 mgag once a day far 3 days plus either EWD or EF-203 orally at dose of 200 mg/kg once a day far 3 days. Thereafterl the changes of blood cells by automatic blood cell counter and the phagocytosis of neutrophils by flow cytometry were examined far 7 days. There was no change in RBC values regardless of administration of either EWD or EF-203 throughout experimental period. But rats receiving CPA plus either EWD or EF-203 showed a significant higher PCV values than those of CPA alone (p<0.01). The numbers of peripheral blood platelets and WBC and the differential count of neutrophils in the ra% receiving CPA plus either EWD or EF-203 were significantly higher (p<0.05 to 0.01) than those of CPA alone. Moreover, these rats showed significanly enhanced phagocytoses of neutrophils when compared to rats with CPA alone (p<0.01). These result suggested that chicken egg white derivatives including EWD and EF-2% have immunomodulatory effects in regard to the increase of platelets, WBC, differential count of neutrophils, PCV, and the enhancement of phagocytic activity of neutrophils in immunosuppressed rats by CPA. Thus, co-adminstration of chicken egg white derivatives will be able to reduce the side effects in the animals treated with antitumor agents.

본 연구는 인간의 체외수정 program으로 부터 생산된 여분의 배반포기 배를 이용하여 현미경에 의한 형태학적 판정과 differential labelling 기법을 이용한 세포 수의 상관관계를 조사하고자 실시하였다. 공시된 인간 배반포기 배는 체외수정 후 5일째에 36명의 환자로부터 76개를 얻어 배반포강의 확대와 투명대 두께의 감소를 기준으로 early (ErB), early expanding (BEB), middle expanding (MEB) 및 expanded blastocyst (EdB)로 구분하였다. 분류된 배반포기 배의 크기와 투명대의 두께를 micrometer로 측정하였을 때, 그 크기는 각각 $148.8-217.6{\mu}m$, $1.2-14.4{\mu}m$로 나타나 같은 배양조건에서 생산된 배아라도 그 차이는 크게 나타났다. Hoechst 염색을 이용하여 배반포기 배의 총 세포수를 조사하였을 때, 체외수정 후 5일째 생산된 배반포기 배는 ErB $(39.1{\pm}3.6)$ 에서 EdB $(89.6{\pm}3.3)$ 로 진행되는 동안 두배에서 세배정도 증가되는 양상을 나타내었다. 또한, differential labelling기법 을 이용한 배반포기 배의 inner cell mass (ICM) 와 trophectoderm (TE) 세포수 조사 결과, 각각 $11.9{\pm}1.8-22.2{\pm}4.3$, $24.5{\pm}3.6-70.0{\pm}7.7$을 나타내어 발달이 진행될수록 ICM과 TE세포수도 증가되는 것을 알 수 있었다. 특히, 형태학적으로 약한 ICM으로 판정된 EdB의 경우 differential labelling 후, 역시 적은 ICM 세포수를 나타내어 형태학적 판정과 세포수간에 밀접한 상관관계가 있음을 알 수 있었다. 따라서, ICM과 TE를 differential labelling하는 기법은 인간 배반포기 배의 quality를 평가하는데 매우 유용한 기법으로 형태학적인 구분과 병용된다면 인간 배반포기 배 이식 program의 임신율 증진을 위한 배아 선별의 중요한 자료로서 이용될 수 있다는 것을 시사한다.

Objective: This study was to compare the characteristics between parthenogenetic mES (P-mES) cells and in vitro fertilization mES cells. Materials and Methods: Mouse oocytes were recovered from superovulated 4 wks hybrid F1 (C57BL/6xCBA/N) female mice. For parthenogenetic activation, oocytes were treated with 7% ethanol for 5 min and $5{\mu}g$/ml cytochalasin-B for 4 h. For IVF, oocytes were inseminated with epididymal sperm of hybrid F1 male mice ($1{times}10^6/ml$). IVF and parthenogenetic embryos were cultured in M16 medium for 4 days. Cell number count of blastocysts in those two groups was taken by differential labelling using propidium iodide (red) and bisbenzimide (blue). To establish ES cells, b1astocysts in IVF and parthenogenetic groups were treated by immunosurgery and recovered inner cell mass (ICM) cells were cultured in LIF added ES culture medium. To identify ES cells, the surface markers alkaline phosphatase, SSEA-1, 3,4 and Oct4 staining were examined in rep1ated ICM colonies. Chromosome numbers in P-mES and mES were checked. Also, in vitro differentiation potential of P-mES and mES was examined. Results: Although the cleavage rate (${\geq}$2-cell) was not different between IVF (76.3%) and parthenogenetic group (67.0%), in vitro development rate was significantly low in parthenogenetic group (24.0%) than IVF group (68.4%) (p<0.05). Cell number count of ICM and total cell in parthenogenetic b1astocysts ($9.6{\pm}3.1,\;35.1{\pm}5.2$) were signficantly lower than those of IVF blastocysts ($19.5{\pm}4.7,\;63.2{\pm}13.0$) (p<0.05). Through the serial treatment procedure such as immunosurgery, plating of ICM and colony formation, two ICM colonies in IVF group (mES, 10.0%) and three ICM colonies (P-mES, 42.9%) in parthenogenetic group were able to culture for extended duration (25 and 20 passages, respectively). Using surface markers, alkaline phosphatase, SSEA-l and Oct4 in P-mES and mES colony were positively stained. The number of chromosome was normal in ES colony from two groups. Also, in vitro neural and cardiac cell differentiation derived from mES or P-mES cells was confirmed. Conclusion: This study suggested that P-mES cells can be successfully established and that those cell lines have similar characteristics to mES cells.
