배경: 폐암은 근치적 절제술이 가장 좋은 치료법이나 수술 후에 재발한 경우나 수술 시기가 지난 경우에는 항암 화학요법의 중요성이 강조된다. 항암 치료 전에 감수성 있는 항암 화학 치료제가 선별되어진다면 치료 효과를 극대화할 수 있다. 신피막하 분석법은 흉, 복부 종양의 생체 내 검사법으로 중요성이 인정되고 있고 항암 감수성 검사로서도 짧은 기간 내에 판별이 가능한 이점이 있다. 신장은 각종 암세포의 이식 장소로 잘 알려져 있으나 비장이나 간에서의 이식 성적을 비교한 연구는 없는 실정이다. 인체 암세포 이식의 실험방법 중에 비장과 간장에 암 세포주를 이식하였을 경우와 신장에 시행되는 신피막하 분석법에 의한 성장의 차이점 유무를 평가하였다. 대상 및 방법: 인체 폐암 세포주(SW-900 G IV)를 RPMI 1640 (Leibovitz L-15 medium)배지에서 배양하여 fibrin clot으로 만들어 $10^{8}$ 개의 암세포가 포함되도록 한 후 3${\times}$${\times}$3mm의 크기로 Spague Dawely (S.D.) 암컷 쥐의 신, 비장 및 간 피막하에 이식하였다. 이식 후 1일부터 6일간 면역억제를 위하여 cyclosporin-A (80 mg/kg)를 피하투여하였다. 이식 전후 실험동물의 체중 변화, 종양의 성장 여부 및 종양의 크기를 계측하고 병리 조직 검사와 혈청 내 암 표지자 검사를 실시하여 비교하였다. 걸과: 실험 5.D. 쥐의 체중 변화는 대조군이나 실험 군 모두에서 체중 증가가 있었다. 혈청 내 암 표지자의 정량 검사 결과 Cyfra 21-1은 검출되지 않았고, CEA및 NSE는 의미 있는 변화가 없었으며, SCC-Ag이 실험 군에서 유의한 증가가 있었다. 비장에 이식한 폐암 세포주의 성장이 신장 및 간장에 비해 더 증가된 결과를 보였다. 표면적, 두께와 용적 모두가 비장에서 유의한 증가를 나타내었다. 이식 성공률은 신장이 80%, 비장이 76.7%, 간장이 43.3%이었다. 병리학적 검사 결과 신장에는 비교적 둥글게 성장하며 크기는 제일 작았으며 성장 방향이 일정한 모양을 보이는 특징이 있으며 비장은 성장이 잘되어 제일 큰 종양을 형성하나 불규칙한 성장과 위성 종양(satellite tumor)이 빈번히 발견되었으며 현미경적으로는 혈관 신생과 함께 종양 혈전이 발견되었다. 간장은 간 내부로 침투 성장하여 이식 성공률이 가장 저조하며 현미경적 소견은 응고성 괴사와 점액양 섬유성 병변을 가지는 특징을 보였다. 걸론: 이식 성공률은 신장과 비장이 높으나, 성장이 일정하고 계측이 용이한 것은 신장이었다. 혈청 암 표지자는 SCC-Ag이 가장 조기에 반응하였으며, Cyfra 21-1은 조기에 검출되지 않았다. 이상에서 감수성 검사를 위한 종양이식 실험에 이용하기에 가장 적합한 장기는 신장을 이용한 신피막하 이식법으로 생각되며, 조기에 유용한 암표지자 검사는 SCC-Ag 정량법이라고 판단된다.

Severe hypercalcemia is rarely encountered in children, even though serum calcium concentrations above 15-16 mg/dL could be life-threatening. We present a patient having severe hypercalcemia and azotemia. A 14-year-old boy with no significant past medical history was referred to our hospital with hypercalcemia and azotemia. Laboratory and imaging studies excluded hyperparathyroidism and solid tumor. Other laboratory findings including a peripheral blood profile were unremarkable. His hypercalcemia was not improved with massive hydration, diuretics, or even hemodialysis, but noticeably reversed with administration of calcitonin. A bone marrow biopsy performed to rule out the possibility of hematological malignancy revealed acute lymphoblastic leukemia. His hypercalcemia and azotemia resolved shortly after initiation of induction chemotherapy. Results in this patient indicate that a hematological malignancy could present with severe hypercalcemia even though blast cells have not appeared in the peripheral blood. Therefore, extensive evaluation to determine the cause of hypercalcemia is necessary. Additionally, appropriate treatment, viz., hydration or administration of calcitonin is important to prevent complications of severe hypercalcemia, including renal failure and nephrocalcinosis.

Backgrounds/Aims: Although cancer survivors are at higher risk of developing second primary malignancies, cancer surveillance strategies for them have not yet been established. This study aimed to identify first primary cancers that had high risks of developing second primary exocrine pancreatic cancer (EPC). Methods: Data on individuals diagnosed with primary cancers between 1993 and 2017 were obtained from the Korea Central Cancer Registry. The standardized incidence ratios (SIRs) of second primary EPCs were analyzed according to the primary tumor sites and follow-up periods. Results: Among the 3,205,840 eligible individuals, 4,836 (0.15%) had second primary EPCs, which accounted for 5.8% of the total EPC patients in Korea. Between 1 and 5 years after the diagnosis of first primary cancers, SIRs of second primary EPCs were increased in patients whose first primary cancers were in the bile duct (males 2.99; females 5.03) in both sexes, and in the small intestine (3.43), gallbladder (3.21), and breast (1.26) in females. Among those who survived 5 or more years after the diagnosis of first primary cancers, SIRs of second primary EPCs were elevated in patients whose first primary cancers were in the bile duct (males 2.61; females 2.33), gallbladder (males 2.29; females 2.22), and kidney (males 1.39; females 1.73) in both sexes, and ovary (1.66) and breast (1.38) in females. Conclusions: Survivors of first primary bile duct, gallbladder, kidney, ovary, and female breast cancer should be closely monitored for the occurrence of second primary EPCs, even after 5 years of follow-up.

Toxoplasmngon gondii의 세포내 배양에 적합한 숙주 세포 주를 찾기 위하여 정상 세포 2종류(MDCK-canine kidney cells; Vero-monkey kidney cells) 및 암세포 6종류(A 549, PC 14-human lung cancer cells; SNU 1, SNU 16, MKN 45-human stomach cancer cells; HL-60-human promyelocytic leukemia cells)를 대상으로 하여 각 세포 주의 T.gondii 감염에 대한 감수성을 형태학적 관찰 및 3H-uracil 흡수 시험을 통하여 비교하였다. T.gondii 대한 감수성은 A 549 및 PC 14 세포가 가장 높았고, Vero, HL-60, MDCK 및 SNU 1 세포가 그 다음, SNU 16 및 MKN 45 세포는 가장 감수성이 낮았다. 또한 각 세포 주에 있어서 T.gondii 감염 후 충체증식 정도를 정량화하여 12시간, 36시간 및 60시간에 각각 측정한 바 충체 수를 적게($2{\times}10^5/ml$) 투여했을 때는 A 549, PC 14, Vero, MDCK 세포들에서 감염 60시간까지 충체의 분열 증식이 계속 증가하였고, 충체 수를 많이($50{\times}10^5/ml$) 주입하였을 때는 대부분의 세포들에서 감염 12시간에 최고의 증식을 보이다가 이후 증식이 감소하였다. 이상의 결과로 보아 기son사거 분리 계대 및 충주(strain) 확립을 위해서는 A 549 및 PC 14 세포가 가장 적합할 것으로 판단되며, 충체 주입 수 및 배양 시간별로 충체의 증식 정도가 다름을 알 수 있었다.

Cisplatin is often effective in cancer treatment, but its clinical use is limited because of its nephrotoxicity. We have synthesized new platinum(II) coordination complexes (PC-1 & PC-2) containing trans-${\iota}$ and cis-1,2-diaminocyclohexane (DACH) as carrier ligands and L-3 -phenyllactic acid (PLA) as a leaving group with the aim of reducing nephrotoxicity but maintaining its anticancer activity. In this study, new platinum(II) complex compounds were evaluated for selective cytotoxicity on cancer cell-lines and normal kidney cells. The new platinum complexes have demonstrated high efficacy in the cytotoxicity against human bladder carcinoma cell-lines (T-24/HT-1376). The cytotoxicity of these compounds against rabbit proximal renal tubular cells and human renal cortical tissues, was determined by MTT assay, the [3H]-thymidine uptake and glucose consumption test, and found to be quite less than those of cisplatin. Based on our results, these novel platinum compounds appear to be valuable lead compounds with high efficacy and low nephrotoxicity.

According to the traditional Korean medicine (TKM), kidney has been recognized as the roof of innate endowment because it plays an important role in the birth, growth, sexual reproduction, and aging. Kidney essence insufficiency syndrome (KEIS) is caused when kidney is impaired. KEIS is characterized by retarded development, decreased reproduction, tinnitus, loosening of teeth, and loss of hair and forgetfulness. In traditional Chinese medicine, KEIS mouse model was established by use of threatinjuring the kidney combined with over-fatigue. However, the TKM theory-based KEIS experiment model has not been described correctly. In the present study, we suggest a new KEIS experiment model including following cases; 1) weakness of father essence and mother blood, 2) life nurturing during pregnancy, 3) full-term gestation period.

In view of obtaining potential anticancer compounds, we studied the inhibitory activity and the cytotoxic effects of a candidate compound in cancer cells. The cytotoxic effects of cannabidiol (CBD) in vitro were evaluated in NIH3T3 fibroblasts, B16 melanoma cells, A549 lung cancer cells, MDA-MB-231 breast cancer cells, Lenca kidney cells and SNU-C4 colon cancer cells. The cells were cultured in various concentrations of CBD for 48 h and 25 ${\mu}$M of CBD for 6-36 h. The cells were observed to exhibit inhibitory effects of the cell viability in their growth, and then cytotoxicity was estimated. The inhibitory activity of CBD was increased in all cancer cells and showed especially strong increment in breast cancer cells. The cytotoxicity of CBD increased in a dose- and time-dependent manner with growth inhibition in all cancer cell lines. Also, to assess the membrane toxicity induced by CBD, we investigated lactate dehydrogenase (LDH) release. After treatment with various concentrations of CBD, LDH release rate of cancer cells was accelerated. On the other hand, in the induction of cell death, caspase-3, -8 and -9 activations were detected in cancer cells after treatment with various concentrations of CBD, and CBD effectively induced activity of caspase-3, -8 and -9 in A549 lung cancer cells, MDAMB-231 breast cancer cells and Renca kidney cells. Therefore these results suggest that CBD has a possibility of anticancer agents and anticancer effects against cancer cells by modulation of apoptotic pathway in the range of 5-80 ${\mu}$M concentration.

Background: Acute kidney injury is an important issue in chemotherapy receiving patients an neutrophil gelatinase-associated lipocalin has been proposed as a novel marker. We here aimed to assess the role of urinary levels for assessment after platin exposure. Materials and Methods: Patients who had treated with cisplatin or carboplatin or oxaliplatin containg regimens were included in this study. Baseline and postchemotherapy serum urea, creatinine, urine neutrophil gelatinase-associated lipocalin and urine creatinine levels were determined. To avoid the effects of hydration during chemotherapy infusion the urinary neutrophil gelatinase-associated lipocalin/urine creatinine ratio was used to determine acute kidney injury. Results: Of a total of 42 patients receiving platin compounds,14 (33.3%) received cisplatin containing regimens, 14 (33.3%) received carboplatin and 14 (33.3%) oxaliplatin. The median age was 60 (37-76) years. Nineteen of the patients (45.2%) had lung cancer, 12 (28.6%) colorectal cancer and 11 (26.2%) others. The median pre and post chemotherapy urine neutrophil gelatinase-associated lipocalin/urine creatinin ratio was 15.6 ng/mg and 35.8 ng/mg (p=0.041) in the cisplatin group, 32.5 ng/mg and 86.3 ng/mg (p=0.004) in the carboplatin group and 40.9 ng/mg and 62.3 ng/mg (p=0.243) in the oxaliplatin group. Conclusions: Nephrotoxicity is a serious side effect of chemotherapeutic agentslike cisplatin and carbopaltin, but only to a lower extent oxaliplatin. All platin compounds must be used carefully and urine neutrophil gelatinase-associated lipocalin measurement seems to be promising in detecting acute kidney injury earlier than with creatinine.

The anticancer potency of the ethanolic extract of Terminalia arjuna on N-nitrosodiethylamine (DEN) induced hepatocellular carcinoma in Wistar albino rats was studied. Single intraperitoneal injection of DEN was administrated to induce liver cancer. After two weeks, phenobarbital (PB) was given orally for fourteen weeks to promote the cancer. The cancer bearing animals treated with ethanolic extract of T.arjuna (400 mg/kg body weight) for 28 days. Nucleic acids such as deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) were estimated in liver and kidney of control and experimental animals. Certain marker enzymes viz, alanine aminotransaminase (ALT), aspartate aminotransaminase (AST), acid phosphatase (ACP), alkaline phosphatase (ALP), 5'-nucleotidase (5'ND) and lactate dehydrogenase (LDH) were assayed in serum, liver and kidney of control and experimental animals. The levels of DNA and RNA were significantly increased in cancer bearing animals. The activities of ALT, AST, ACP, ALP, 5'ND, and LDH were significantly (P<0.001) increased in serum of cancer bearing animals. On the other hand, the levels of ALT, AST were decreased (P<0.001) and ACP, ALP, 5'ND, and LDH were significantly increased (P<0.001) in liver and kidney. These changes were reversed to near normal in drug treated animals. These observations suggest that the ethanolic extract of T.arjuna possess anticancer activity.

Tumor lysis syndrome is a serious complication of malignancy, resulting from the massive and rapid release of cellular components into the blood. Generally, it occurs after initiation of chemotherapy. The onset of spontaneous tumor lysis syndrome (STLS) before anti-cancer treatment is rare and occurs mostly in Burkitt lymphoma and non-Hodgkin's lymphoma. There are only a few case reports in children. Here, we report a case of STLS secondary to T-cell acute lymphoblastic leukemia (ALL), which presented with urinary stone and subsequent acute kidney injury with severe hyperuricemia. Occult malignancy should be considered in case of unexplained acute kidney injury with extreme hyperuricemia.
