The glutathione S-transferases (GSTs) are a family of enzymes involved in the detoxification of a wide range of chemicals, including important environmental carcinogens, as well as chemotherapeutic agents. In the present study 294 acute leukemia cases, comprising 152 of acute lymphocytic leukemia (ALL) and 142 of acute myeloid leukemia, and 251 control samples were analyzed for GSTM1 and GSTT1 polymorphisms through multiplex PCR methods. Significantly increased frequencies of GSTM1 null genotype (M0), GSTT1 null genotype (T0) and GST double null genotype (T0M0) were observed in the both ALL and AML cases as compared to controls. When data were analyzed with respect to clinical variables, increased mean levels of WBC, Blast %, LDH and significant reduction in DFS were observed in both ALL and AML cases with T0 genotype. In conclusion, absence of both GST M & GST T might confer increased risk of developing ALL or AML. The absence of GST enzyme might lead to oxidative stress and subsequent DNA damage resulting in genomic instability, a hallmark of acute leukemia. The GST enzyme deficiency might also exert impact on clinical prognosis leading to poorer DFS. Hence GST genotyping can be made mandatory in management of acute leukemia so that more aggressive therapy such as allogenic stem cell transplantation may be planned in the case of patients with a null genotype.

TP53 is the mostly commonly mutated gene in many cancers and the P53 tumor suppressor protein is involved in multiple cellular processes, including transcription, DNA repair, genomic stability, senescence, cell cycle control and apoptosis. A common single nucleotide polymorphism located within the proline rich region of TP53 gene at codon 72 in exon 4 encodes either proline or arginine. TP53 Arg 72 is more active than TP53 Pro 72 in inducing apoptosis. The aim of this study was to understand the association of the 72 codon polymorphism with acute leukemia development and prognosis. A total of 288 acute leukemia cases comprising 147 acute lymphocytic leukemia (ALL) and 141 acute myeloid leukemia (AML), as well as 245 controls were recruited for analysis of the TP53 72 polymorphism using PCR-RFLP method. Significant association of homozygous arginine genotype with AML was observed (${\chi}^2$- 133.53; df-2, p < 0.001. When data were analyzed with respect to clinical variables, elevation in mean WBC, blast %, LDH levels and slight reduction in DFS in ALL cases with the arginine genotype was observed. In contrast, AML patients with Pro/Pro had elevated WBC, Blast%, LDH levels with slightly reduced DFS. Our study indicates that Arg/Arg genotype might confer increased risk to development of acute myeloid leukemia.

Thirty species of Korean medicinal plants which have been frequently used in Oriental herb prescriptions were evaluated on their acute toxicity and potential antitumor activities against P-388 lymphocytic leukemia. The criteria for toxicity evaluation of measuring weight loss, toxicity day survivors and computing log cell kill indicated that 11 species possessed acute toxicity according to the doses administered. No significant antitumor activities were observed while the root of Angelica gigas Nakai (Umbelliferae) exhibited only 24% increased life span.

만성 림프구성 백혈병은 오랜기간에 걸쳐서 발전하는 전신질환이며, 급성 백혈병에서 보이는 것보다 더욱 성숙되고 잘 분화된 림프구가 혈액과 골수에 존재하는 것을 특징으로 한다. 본 증례보고에서는 발작, 복수의 임상 증상과 전염성 성병성 종양에 대한 치료경력이 있는 2년령의 거세된 잡종견을 다루고 있다. 여러 가지 진단 절차를 통하여 만성 림프구성 백혈병으로 진단내렸고, chlorambucil과 prednisolone을 이용한 항암치료를 현재까지 적용해 오고 있다. 초기내원 시 보였던 대부분의 증상에 대한 개선을 볼 수 있었으며, 환자의 삶의 질은 향상되었다.

Purpose: This study was done to describe psychosocial adjustment of adolescents who have survived childhood acute lymphocytic leukemia (ALL). Method: Out of a total of 16 adolescents ($11{\sim}20$ years old) registered at the Pediatric Oncology Clinic at one university affiliated hospital, 13 adolescents agreed to participate in this study. The data were collected through in-depth interviews using a semi-structured questionnaire. The contents of the interviews were analyzed using the inductive content analysis method. Result: Three main categories were identified 'personal characteristics', 'coping patterns', and 'interpersonal relationship'. Personal characteristics included self-praise, self-confidence, altruism, being worrisome, and being difficult. Coping patterns included positive thinking, activeness, and avoidance. Interpersonal relationship included appreciation, intimacy, burdened by over protectiveness, and feelings of regret and equality as peers. Conclusion: The results indicate that adolescents who have survived childhood cancer have both positive and negative experiences. It is suggested that care providers identify and support the strengths of the adolescents in order to help them to adjust more positively after the experience of childhood cancer.

Purpose: To investigate the impact of hyperglycemia during inductive treatment on the prognosis of acute lymphocytic leukemia (ALL) in children. Materials and Methods: Clinical data of 159 ALL childhood cases were reviewed. The patients were divided into the hyperglycemia group (fasting $glucose{\geq}126mg/dl$ and/or random blood $glucose{\geq}200mg/dl$) and the euglycemia group according to the blood glucose values. The X2 test was performed to compare the complete remission rates of the two groups, and Kaplan-Meier and log-rank tests were performed to compare the 5-year overall and relapse-free survival. Results: The incidence of hyperglycemia in the $age{\geq}10-year-old$ group was higher than the younger-age group (P=0.009). Values in the interim- and high-risk groups were higher than the standard-risk group (P=0.028), while there was no significant difference between genders (P=0.056). The complete remission rates of the 2 groups demonstrated no significant difference (P=0.134), while the 5-year OS of the hyperglycemia group was lower than in the euglycemia group ($83.8{\pm}6.0%$ vs $94.9{\pm}2.4%$, P=0.014). The 5 -year RFS was significantly lower than the euglycemia group ($62.9{\pm}8.7%$) vs $80.2{\pm}9.1%$, P<0.001). Conclusions: Children with $age{\geq}10year$ old, and in the middle- and high-risk groups appear prone to complicating hyperglycemia during inductive chemotherapy, associated with lower 5-year OS and RFS.

Bronchiolitis obliterans (BO), which is associated with graft-versus-host disease after allogenic hematopoietic stem cell transplantation, is a major obstacle to survival after bone marrow transplantation due to its gradual progress, eventually leading to respiratory failure. Pumpless extracorporeal interventional lung assist (iLA) is effective in treatment of reversible hypercapnic respiratory failure. In this paper, we present a 23-year-old female patient who underwent allogeneic peripheral blood stem cell transplantation (PBSCT) for acute lymphocytic leukemia. After 6 months, she complained of shortness of breath and was diagnosed with BO. Five months later, she developed an upper respiratory tract infection that worsened her BO and caused life-threatening hypercapnia. Since mechanical ventilation failed to eliminate $CO_2$ effectively, iLA was applied as rescue therapy. Her hypercapnia and respiratory acidosis showed significant improvement within a few hours, and she was successfully weaned off iLA after 12 days. This is the first case report of iLA application for temporarily aggravated hypercapnia of PBSCT-associated BO followed by successful weaning. This rescue therapy should be considered in ventilator-refractory reversible hypercapnia in BO patients.

Fiftythree species(35 families and 52 genera)of Korean medicinal plants which have been frequently used in oriental herb prescriptions or have been used as folklorics were evaluated on their short term acute toxicity and potential antitumor activities against P-388 murine lymphocytic leukemia model in vivo. Among these plants Acorus gramineus (Araceae), Agrimonia pilosa (Rosaceae), Aralia elata (Araliaceae), Dryopteris crassirhizoma (Aspidiaceae), Syringa reticulata (Oleaceae) and Calystegia japonica (Convolvulaceae) exhibited potent acute toxicity resulting from severe weight loss and death. Agrimonia pilosa (Rosaceae) showed about 33% of increased life span in comparison with that of control group mouse, but others exhibited no significant antitumor activities.

We experienced a case of rhinocerebral form of mucormycosis in a 9-year-old male suffered from acute lymphocytic leukemia (FAB $L_2$). On 15th day of induction chemotherapy (Hospital day 23) pain, tenderness and swelling on left maxillary area of face were noticed. We confirmed mucormycosis by biopsy of mass in left maxillary sinus. He expired on Hospital day 47.
