Recombinant interleukin-2 (IL-2) has been demonstated as an antineoplastic agent in mice and human, and the route of administration is important to IL-2-induced therapeutic responses. Therefore, the current experiment was undertaken to clarify the effect of IL-2 administration route on antitumor response against subcutaneous Meth-A tumor in mice. At the beginning of each experiment, normal BALB/c mice were injected subcutaneously with $5{\times}10^6$ Meth-A tumor cells. Beginning on day 7, experimental groups were treated with a 5-day course of IL-2 (intraperitoneal or subcutaneous injection of 30, 000 IU every 12 hours for 5 days). The result of this experiment revealed that Meth-A tumor grew progressively in control mice. Intraperitoneal IL-2 treatment decreased significantly tumor growth and prolonged survival, compared with control mice. Subcutaneous IL-2 treatment decreased significantly tumor growth until day 11 and tumor cells, grew progressively thereafter, but mice in this group survived longer than control mice.

Seven organic arsine compounds are synthesized as potential anti-tumor agents are subjected to the screening test of activity against SN-36 Leukemia, Sarcoma 180 and Ehrlich ascites carcinoma. Three compounds, namely N-(5-Nitrofroyl)-p-arsanilic acid, N-(2, 4-Dihydroxybenzoethyl)-p-arsanilic acid and N-$\alpha$(p-arsanilido) acetyl thiourea of the all synthesized compounds showed comparatively potential activities against experimental ascitic tumors both through cytological findings and survival duration.

3-Amino-2-phenylthietane derivatives were considered as a useful tool to elusidate the mechanism of inhibiton of MAO by tranylcypromine-type inhitors. The synthesis of 3-benzoylamino-2-phenylthieetane, 3-amino-2-phenylthietane, and 3-N, N-dimentylamino-2-p-nitrophenythietane was attempted using the reaction between 1, 3 dihalogeno alkanes with alkali sulfide. When 1-pheny1-1, 3-dihalo-2-benzolaminopropane was treated with sodium sulfide, 2-pheny 1-4 benzylidene-2-oxazoline was isolated, indicating the case of elimination reaction compared to ring formation. The reaction of 1-p-nitropheny1-1, 3-dichloro-2-N, N-dimethylaminopropane with sodium sulfide gave bis (1-p-nitropheny1-2-N, N-dimethylamino-3-chloropropane)sulfide. The mechanism of reaction was discussed.

Many types of compounds have been isolated from higher plants till now, that is, alkaloids, terpenes, lignans, steroids and so on. One of them, named as RA series Cyclic hexapeptides isolated from Rubia akane and R. cordijofia also have strong antineoplastic activity against various types of tumors. Till now 10 kinds ofRA series compounds were isolated and named as RA - I, II, III, IV, V, VI, VII, VIII, IX and X. Moreover,monogl-ucoside of RA - V newly Isolated from same plant. Many kinds of derivatives including natural RAcompounds were tested for QSAR, and one of them, RA - VII was screened up as a most suitable substance asan antitumor agent. RA - VII(=RA-700) has strong cytotoxic activity against KB cells, P388 Iymphocyticleukemia and MM2 mammary carcinoma cells. RA - VII has been under investigation for Phase I clinical trials.

Some coumarins were sythesized for the screening of their cytotoxic activities against L1210 cell. Of the conmarins sythesized, 6, 7-dihydroxycoumarin (esculetin) and 7, 8-dihydroxycoumain (dephnetin) as coumarins with dioxygenated A-ring, and 6-acetoxy-5, 7-dimethoxycoumarin and5, 7-dimethoxy-6-hydroxycoumarin as trioxygenated ones, show considerable cytotoxic activities, ED 50 being 4. 3, 8. 8, 17.2 and 5.5 $\mu$g/ml in the same other as the substances. THe extent oxygenation of the A-ring and the positions of the oxygen functions eventually play an important role for the cytotoxic activity.

Recombinant interleukin-2(IL-2) has demonstrated as an antineoplastic agent in mice and human, but the relatively low response rates observed in clinical trials. Therefore, the present study was undertaken in order to evaluate therapeutic activities of IL-2 for the establishment of therapeutic applications. At the onset of the experiment, normal C3H/HeN mice were injected with 5$\times$10$\^$6/ RD-995 tumor cells, murine ultraviolet radiation-induced fibrosarcoma, intraperitoneally. Beginning on day 6, experimental groups were treated with a 5-day course of IL-2(subcutaneous injection of 30,000 IU every 12 hours for 5 days). The result of this experiment revealed that body weight gradually decreased from 20th day in control mice. Subcutaneous IL-2 therapy prevented partially decrease body weight, and prolonged survival of mice compared with control group.

To evaluate the role of imidazolidinone moiety of potential anticancer 4-phenyl-1-arylsulfonylimidazolidinones 1 for their cytotoxicity conformationally similar 4-phenyl-2-arylsulfonylaminooxazolines 2 were synthesized and compared their cytotoxicities with those of the corresponding 1. Compounds 2 showed much reduced activity compared to N-arylsulfonylimidazolidinones 1. This result might indicate that the imidazolidinone ring of 1 have the other roles for the activity as an essential structural motif in addition to conformational contribution .

Mandatory registration of clinical trials in public registry can ensure the transparency of clinical trials. Public clinical trial registry of can provide current chronological and geographical distribution of clinical trial throughout the country. We used public clinical trial registry provided by Ministry of Food and Drug Safety to analyze current status of clinical trial from 2014 to 2016 in South Korea. The number of clinical trials in antineoplastic and immunomodulating agents area was the greatest, followed by cardiovascular system and antiinfectives for systemic use as a whole. From 2014 to 2016, overall number of clinical trials decreased while the number of phase I clinical trials increased. Seoul accounted for more than half number of clinical trials in Korea. Supports for clinical trials in non-metropolitan area needs to be considered.

소아의 종양성질환은 출생 첫해에 가장 많고, 2-3세경에 두 번째로 많이 나타난다. 소아에서는 급성 백혈병, 임파선암, 뇌종양, 연조직 종양 그리고 신장 종양이 일반적이다. 조기진단과 의학의 발달로 치료결과가 향상되고 치료후 생존율 또한 높아지는 추세이나, 항암화학요법, 방사선 및 조혈모세포 이식 등의 치료과정에 동반되는 전신 및 국소적합병증 또한 심각한 문제로 나타난다. 구강조직은 항암치료의 독성에 특히 예민하고 구강내 병소가 나타나는 경우가 많다. 소아치과의사는 종양성질환으로 다양한 항암치료를 받는 어린이의 치료 전후에 삶의 질에 영향을 줄 수 있는 치과적 문제를 진단하고 예방 및 관리에 매우 중요한 역할을 담당한다. 따라서 소아치과의사를 포함한 치과종사자는 환자의 병력, 치료과정, 건강상태에 따른 합병증을 예방 또는 처치하기 위한 개별적 구강관리지침을 제공하는 것이 필요하다. 이 논문에서는 소아에서 종양성질환을 치료중인환자, 특히 항암화학요법, 방사선 요법 및 조혈모세포이식환자에 대한 치료전후의 구강관리에 대하여 알아본다.
