Colchicine is a drug well known for its use in the therapy of acute attacks of gouty arthritis. Two death caused by oral ingestion of colchicine was reported. Two persons were all women. The one was 34 years old woman and with his boyfriend in a inn and the other was a housewife. The first one was a alcoholic but his boyfriend was afflicted with gout. So her boy friend carried over about 60 tablets of colchicine, 4 tablets of naltrexone and 22 tablets of fluoxetine. After her death there were remained colchicine, 2 tabs, naltraxone 4 tabs and fluoxetine 22 tabs. (omitted)

Polyploidy has opened a new horizon for selection to sculpt a variety of new gene functions, traits, and lineages. The aim of this study was to investigate the efficacy of the colchicine concentration, temporal changes, and suitable material for inducing effective tetraploid plants of Codonopsis lanceolata. A total of 180 individuals from 16 treatment groups were germinated, and exposed to different concentrations of Colchicine. The plant height of the diploid (18.1 cm) was slightly shorter than that of the tetraploid (13.4 cm). The fresh weight of the main root in the diploid (0.5 g) was 4-fold higher than the tetraploid (2.2 g). The colchicine-treated plant regeneration rate in C. lanceolata was decreased at the elevated concentration of colchicine. A total of 126 individual plants were regenerated in the entire treatment group and tetraploid (2n=4x=32) plants were obtained. In particular, 5 individuals of the tetraploid plant were induced in the 0.05% colchicine for 6h, which is a higher rate (29.4%) than other regenerated plants. As in the seed treatment result, the plant height of the diploid was significantly higher (10.4 cm) than tetraploid. The root length of the tetraploid (10.1 cm) was longer than the diploid, and the root was also thicker. Taken together, the results obtained from the present study may be helpful for the efficient recovery of such polyploid plants through the in vitro application of colchicine, and may improve the productivity and breeding of C. lanceolata.

The present study was performed to investigate the effects of the colchicine concentrations on chromosome doubling for producing of tetraploid plants of Codonopsis lanceolata, and its effect on plant morphology. A total of 180 individuals germinated from 16 treatment groups, were exposed to various concentrations (0.05-1.0% w/v) of colchicine for different soaking duration (3-24 hour). The highest numbers of tetraploid plants (3) were observed from the lowest concentration of colchicine (0.05%), and one (1) tetraploid plant was obtained from the 0.5% concentration group with a 6 hour treatment. However, no tetraploid individual was observed in any other treatment groups. The plant height of the diploid (18.1 ㎝) was slightly shorter than that of the tetraploid (13.4 ㎝). The fresh weight of the main root in the diploid (0.5 g) was four-fold higher than the tetraploid (2.2 g). The colchicine-treated plant regeneration rate in C. lanceolata was decreased when the plants were subjected to high concentration of colchicine. In particular, the highest number of tetraploid plants (5 and 3) was obtained from the lower concentration (0.05% and 0.1%) of colchicine for 6-hour treatment, which were a higher rate (29.4% and 30%) of regenerated tetraploid plants than other regenerated plants. As in the seed treatment result, the plant height of the diploid was significantly higher (10.4 ㎝) than tetraploid. The higher morphological changes were observed comparatively from tetraploid plants than the diploid.

Hatomarubigins inhibited the growth of various cancer cell lines including multidrug-resistance cells. Hatomarubigins were found to potentiate the colchicine- and vinblastine-induced cytotoxicity against KB-C2 cell, but not the adriamycin-induced cytotoxicity against KB-C2 cells. Hatomarubigins didn't affect the sensitive KB cells. These results suggest that hatomarubigins are specific potentiators of colchicine. Among four hatomarubigins, hatomarubigin A sho- wed the highest synergestic effect on colchine-induced cytotoxicity. Similar effect of hatomarubigin A was found against V79/ADM cells.

After topping, axillary buds of haploid plants derived from cultured anthers were treated with 0.4% aqueous solution of colchicine. Due to the high temperature and dry air at the time of treatment, most of the buds perished. A few months after the colchicine application, however, several shoots arose from the places where the dead buds were originally located. These shoots were mostly diploid. Induction of adventive shoots from the colchicine-treatedaxils was supposed to be rather effective method of obtaining diploid shoots from haploid plants. The diploid plants had larger floral organs than the haploid plants, and had good pollen fertility and seed setting. 24 bivalent chromosomes were observed at MI of the PMC's.

Recurrent pericarditis is rare in children and is considered idiopathic in most cases. Its course is chronic, and preventing recurrences is important for the patient's quality of life. Although a treatment strategy in pediatric recurrent pericarditis has not yet been established, non-steroidal anti-inflammatory drugs (NSAIDs) are the most common treatment for management of this condition, followed by corticosteroids, colchicine, immunosuppressive agents, immunoglobulins, and interleukin-$1{\beta}$ receptor antagonists (e.g. anakinra). Herein, we report a case of recurrent pericarditis with pericardial effusion in a 5-year-old child who presented with fever and epigastric pain. He responded poorly to NSAIDs and corticosteroid therapy, but was successfully treated with colchicine.

The effects of colchicine on the plasma elimination and biliary excretion of various organic anions in rats were examined. Elimination of indocyanine green (ICG) or rose bengal (RB) from plasma was significantly delayed when rats were treated with colchicine (3 mg/kg body weight) 3 hr prior to the administration of the dye. On the other hand, disappearance of sulfobromophthalein (BSP) or bromophenol blue (BPB) from plasma was not influenced by colchicine. The plasma disappearance and biliary excretion of organic anions were kinetically analyzed based on a compartment model, in which the deep compartment and the unknown disposition are incorporated. The transfer rate constants of ICG or RB, $k_{23}$ (from the liver to the deep compartment) and $k_{3B}$ (from the deep compartment to the bile), were decreased by colchicine, but those of BSP or BPB were not changed. A mechanism for the decrease in the $k_{23}$ and $k_{3B}$ values for ICG and RB might be explained by a inhibition of colchicine to the intracellular cytoskeleton. The hepatocellular distribution of RB or BPB was then determined. BPB mainly distributed to the cytosolic fraction, but RB distributed to each hepatocyte organelle. Taken together. it was suggested that ICG or RB is transported through hepatocytes into bile with the aid of the cytoskeleton, whereas BSP or BPB is handled by hepatocytes in a different way.

This study was conducted to find out the effective induction method of tetraploid plants to obtain potential data for cultivating superior varieties by colchicine treatment. The seed germination were decreased by the higher concentration of colchicine treatment and longer soaking time. A total of 907 individuals were germinated in 16 treated plots except control (untreated plot) and 28 tetraploids were induced which was about 3.1% of the number of seed germinated. The plant regeneration rate by colchicine treatment on explant of Prunella vulgaris for. albiflora Nakai under in vitro culture was decreased with the higher concentration of colchicine. While a total of 312 individuals were regenerated in all treatments, the explant was soaked in more than 0.05% for over 1 hour, tetraploid could be obtained. In particular, for the soaking treatment in 0.05% for 6 hours and 12 hours, 37 tetraploids were induced, which was about 57.8% of the number of plant regenerated. In accordance with the observation on doubling of DNA contents in leaf in order to identify polyploid, the peak DNA content of G1 phase was 101.3 for diploid and 197.2 for tetraploid. The result confirmed the doubling of DNA content. Furthermore, the number of chloroplasts per guard cell depending on polyploid was around 10 in diploid and 19.3 in tetraploid, which was around 1.9 times as much as diploid.

흰 쥐 내피세포의 배양에 있어서 세포골격단백의 변화 양상과 심근세포와의 공존 배양시의 영향 그리고 colchicine 이 미치는 영향에 대해 알아보고자 monoclonal antibodies를 이용한 간접면역형광법으로 actin과 tubulin염색을 시행하여 microtubule과 microfilament의 변화 양상을 일령별로 관찰하였다. 실험결과를 요약하면 다음과 같다. 세포질이 넓게 퍼지고 많은 돌기를 가진 세포에서 섬유사형태의 반응이 강하였으며 내피세포가 단층을 형성하면서 섬유사형태의 반응이 약해졌다. 심근세포를 혼합배양한 군에서 내피세포가 단층을 형성하면서 microtubule은 대조군과 같은 수준으로 섬유사형태의 반응이 감소하였으나 microfilament는 여전히 강한 섬유사형태의 반응을 유지하였다. Colchicine을 처리한 군에서 microfilament는 대조군과의 차이점이 발견되지 않았으나 microtubule에서는 colchicine 처리 직후부터 섬유사 형태의 감소경향을 보였으며 1일 이후가 가장 현저한 감소를 보이다가 2일 이후에는 대조군의 수준으로 돌아왔다.
