  • Acute promyelocytic leukemia(APL) is not just the poor grades of treating a type of blood cancer hayeoteul combination with chemotherapy despite concurrent radiation therapy are known to exhibit a greater effect and also works on normal cells to result in side effects. In this study, when after treatment with gamma rays, such as $TNF-{\alpha}$ in order to reduce these side effects was confirmed how affected the cell death of normal cells and cancer cells. HL-60 cells were used as the APL cell line HL-60 cells were differentiated with DMSO for treatment are shown the properties of normal granulocytes was used as a control group. As a result, HL-60 cells treated with $TNF-{\alpha}$ and gamma rays with only showed a cytotoxic effect by inducing the apoptosis cells were put to death. Consequently, $TNF-{\alpha}$ is thought to active substances that can increase the efficiency of cancer treatment to increase the removal of cancer cells when used with low-density gamma-ray treatment in order to eliminate the side effects of chemotherapy.

  • Apoptosis is a crucial mechanism for the proper regulation of homeostasis. BCL-2 family proteins are key molecules which control cellular survival and apoptosis. MCL-1 (myeloid cell leukemia-1) is a pro-survival member of BCL-2 family that promotes the survival of cells, and is highly expressed in diverse cancers including ovarian cancer, leukemia, and cervical cancer. Previously we identified IEX-1 (immediate early response gene X-1) as a binding partner of MCL-1. In the present study, we demonstrated that overexpression of IEX-1 induced apoptosis of ovarian cancer cells. Moreover, IEX-1 significantly attenuated the pro-survival function of MCL-1 in these cells. Also, IEX-1-induced cell death activity was able to be modulated by changes in the expression level of MCL-1. Thus, these results suggest that both IEX-1 and MCL-1 modulate each other's function controlling cellular survival and death and the inhibitory activity of IEX-1 toward MCL-1 may be applied for the development of chemotherapeutics.

  • After esophagectomy, the stomach is used most commonly for the method of reconstruction. However, the stomach may not be large enough to be reached the site of anastomosis when it is above the pharynx. We experienced a double primary cancer of the lower esophagus and the larynx. Total laryngectomy and total esophagectomy were done with cervical pharyngojejunogastrostomy for reconstruction. Free jejunal graft is interposed between the oropharyngeal stump and the stomach is pulled-up. We could restore the alimentary track without tension at the anastomotic site and obtain sufficient blood supply.

  • In order to investigate the effect of the combined dietary animal and vegetable proteins on growing female and male rats and mice. 25 female and 25 male rats of 4 weeks old weighing approximately 43-65g and 47-60g, respectively, were subjected to feeding trials for 4 weeks and then subsequently to metabolic trials for 10 days. In case of mice, 25 female and 25 male mice of 4 weeks old weighing approximately 12-17g and 12-16g, respectively, were equally treated. The dietary energy level was set as 3600 kcal ME/kg, and protein and fat provided respectively 12 and 5% of the dietary energy. The rest 83% of the energy level was supplied with appropriate amounts of starch and glucose. The following results were obtained. The body weight gain of female and male rats were increased as the combined dietary animal protein level increased. Whereas that of male mice was the highest for the diet E(Ap 10+Vp 90). Food efficiencies both of female and male rats were improved as combined dietary of animal protein increased. Male rats were superior to that of female. In the mice, the food efficiency value of male mice was superior to that of female. And the values of the male showed the same fashion as that in the growth rate, although it was not for the female. Protein efficiencies, both of female and male rats, were improved as combined dietary of animal protein level increased. That of male mice was in accord with the body weight gain and food efficiencies. But that of female mice was not accordant. Nitrogen retention of the experimental diets in the same protein level was in proportion to nitrogen intake. That of male mice was improved as animal protein level increased, but, that of female mice was not. Body protein utilizability was found to be superior in mice to rats. Blood serum protein level was not found to be affected by the experimental diets in the same protein level. The best combination ratio of animal and vegetable protein seems to be variable depending on the sex and species of animals, and the best diets for female and male rats and female and male mice were found to be experimental diet A(Ap 10+Vp 90) or diet B(Ap 75+Vp 25), diet C(Ap 50+Vp 50), and diet E(Ap 10+Vp 90), respectively. From the above-mentioned results that there was no difference in growth rate of body weight gain from the weanling period to puberty, and that the protein requirements of rats and mice were different from each other.

  • In order to study the antitumoral effect of meju extracts, which was made with a single inoculum of the microorganism, the cytotoxicity effects on several human leukemia cells such as promyelocytic leukemia cell (HL60), histiocytic lymphoma cell (U937) and acute T-cell leukemia Jurkat cell, and lymphocyte were analyzed by MTT assay. Twenty one microbes, mainly fungal genera, were isolated from Korean traditional mejus of different regions. From those collected isolates, meju was manufactured and extracted with 80% methanol, respectively. Meju methanol extracts exhibited low activites in cytotoxicity tests on HL60 cell, but high antitumoral effects of meju methanol extracts were shown on U937 and Jurkat cells. Meju methanol extracts made with a genera of Mucor, Absidia and Aspergillus showed prominant cytotoxic activities, especially. However all these extracts had no inhibitory effects on the cell growth of lymphocyte under the same conditions.

  • Pulmonary mucormycosis is very rare but has a devastating opportunistic fungal infection in immunocompromised hosts. The infection usually occurs in patients with hematologic malignancy, chronic renal failure, diabetes mellitus, or in solid organ transplant recipients. We experienced a case of pulmonary mucormycosis associated with renal cadeveric allograft recipient who had uncontrolled diabetes mellitus. The patient was successfully treated by surgical resection with Amphotericin B therapy.

  • Bilateral renal enlargement is a very rare manifestation as the primary presenting feature of acute lymphoblastic leukemia. We are reporting an unusual clinical picture of a 9-month-old male patient diagnosed as precusor B-cell lymphoblastic leukemia, who showed bilateral nephromegaly without any hepatosplenomegaly at the time of initial presentation.

  • 혈액 세포 형성 과정인 조혈 작용은 콜로니 자극인자 (Colony Stimulating Factor, CSF)라 불리는 몇 종류의 당 단백질에 의해 조절된다. 이들 자극인자 중, GM-CSF는 다계통에 작용하는 조절인자로서 과립구와 거식세포의 생성을 조절한다고 알려져 있다 한편 GM-CSF는 생체내에서 백혈구의 형성을 조절하는 인자이기 때문에 골수이식을 한 환자 및 화학요법이나 방사선 치료를 받는 암환자에게서 발생하는 백혈구의 감소현상을 완화시키는 역할을 한다. 혈액의 보조화와 관련하여 의학적 효능을 나타낼 것으로 간주되는 GM-CSF를 유전자 재조합 기술로 효모에서 발현, 정제하여 물리화학적 특성 및 역가를 측정하는 것이 이 연구의 기본목적이다.

  • Artificial intelligence application in digital health care has been increasing with its development of artificial intelligence. The convergence of the healthcare industry and information and communication technology makes the diagnosis of diseases more simple and comprehensible. From the perspective of medical services, its practice as an initial test and a reference indicator may become widely applicable. Therefore, analyzing the factors that are the basis for existing diagnosis protocols also helps suggest directions using artificial intelligence beyond previous regression and statistical analyses. This paper conducts essential diagnostic prediction learning based on the analysis of blood cancer factors reported previously. Blood cancer diagnosis predictions based on artificial intelligence contribute to successfully achieve more than 90% accuracy and validation of blood cancer factors as an alternative auxiliary approach.
