A case is reported of a man with malignant fibrous histiocytoma (MFH) in right thigh who developed streptococcal toxic shock syndrome (STSS) during postoperative radiotherapy. Before radiotherapy, a patient complained wax and wane lymphedema following wide excision of tumor mass which was confirmed as MFH. He took some nonsteroidal antiinflammatory drug (NSAID) for about one month. He suffered preexisting hepatitis C virus (HCV) infection, diabetes and well-controlled hypertension. The patient received conventional radiotherapy to right thigh with a total dose of 32.4 Gy at 1.8 Gy per day. At last radiotherapy fraction, cutaneous erythematous inflammation was suddenly developed at his affected thigh. At that time, he also complained of oliguria, fever and chills. The patient was consulted to internal medicine for adequate evaluation and management. The patient was diagnosed as suggested septic shock and admitted without delay. At admission, he showed hypotension, oliguria, constipation, abnormal renal and liver function. As a result of blood culture, Streptococcus pyogenes was detected. The patient was diagnosed to STSS. He was treated with adequate intravenous antibiotics and fluid support. STSS is one of oncologic emergencies and requires immediate medical intervention to prevent loss of life. In this patient, underlying HCV infection, postoperative lymphedema, prolonged NSAID medication, and radiotherapy may have been multiple precipitating factors of STSS.

Transparent, abrasion resistant coatings with 4~13 ${\mu}{\textrm}{m}$ thickness were prepared by spin-coating on polycarbonates with organic/inorganic hybrid solutions, followed by UV curing and heat treatment at 12$0^{\circ}C$ for 12 hours. The coating solutions were composed of inorganic phase and organic phase in 0:100, 20:80, 30:70, 50:50, 80:20 wt% ratios, respectively, mixed with photoinitiator, senaitizer and surfactant. The inorganic phase was formed by sol-gel reaction of TEOS and silane coupling agent MPTMS in 1 : 2 or 2 : 1 molar ratios, the organic phase consisted of difunctional urethane acrylate oligomeric resin, multifunctional acrylate TMPTA and HDDA in 4 : 3 : 3 wt% ratio. The coating systems were investigated by FT-IR, $^{29}$ Si-NMR spectra. In addition, TGA/DSC for thermal analysis and SEM, AFM observation for coated surface were examined. Gererally, the homogeneity of phases, the surface smoothness of coating and abrasion resistance were improved with the higher content of inorganic component. Namely, coating system with below 10 $\AA$ surface roughness and T$_{g}$ of 15$0^{\circ}C$ showed only 10% decrease in light transmittance after abrasion test, whereas uncoated polycarbonate substrate exhibited 46% decrease..

Protective effects of natural components including genistein (4',5,7-trihydroxyisoflavone) from Glycine max MERRILL on the rose-bengal sensitized photohemolysis of human erythrocytes were investigated. Genistein $(10{\sim}100\;{\mu}m)$ suppressed photohemolysis in a concentration-dependent manner, and was more effective than the lipid peroxidation chain blocker, ${\alpha}$-tocopherol (Vit. E). Glycoside of genistein, genistin, the water-soluble antioxidant, L-ascorbate, and the iron chelator, myo-inositol hexaphosphoric acid dodecasodium salt (sodium phytate) did not exhibit protective effect against photohemolysis. L-Ascorbate and sodium phytate stimulated photohemolysis at high concentration $(500\;{\mu}m)$. ${\alpha}$-Carotene 3,3'-diol (lutein), a singlet oxygen $(^1O_2)$ quencher, exhibited pronounced protective effect, an indication that $^1O_2$ is important in photohemolysis sensitized by rose-bengal. Reactive oxygen scavenging activities $(OSC_{50})$ of natural antioxidants including genistein on reactive oxygen species (ROS) generated in $Fe^{3+}-EDTA/H_2O_2$ system using the luminol-dependent chemiluminescence assay were in the order of sodium phytate > L-ascorbate > ${\alpha}$-tocopherol > genistein > genistin. $OSC_{50}$ value of genistein, genistin, ${\alpha}$-tocopherol, L-ascorbate, and sodium phytate were 41.0, 109.0, 9.0, 5.2, and $0.56{\mu}m$ respectively. The order of free radical (1,1-diphenyl-2-picrylhydrazyl, DPPH) scavenging activity $(FSC_{50})$ was L-ascorbate > ${\alpha}$-tocopherol > genistein > genistin. These results indicate that genistein can function as an antioxidant in biological systems, particularly skin exposed to solar UV radiation by scavenging $^1O_2$ and other ROS, and to protect cellular membranes against ROS.

The responses of GA$_3$ treatment on the culm length, internode elongation, number of internodes elongated and on the panicle length of 115 Japonica rice cultivars were studied. One spray with 50 ppm GA$_3$ was made at about 30 days before heading. Generally short culm cultivars showed better elongation responses than taller ones and a few taller cultivars showed reduced culm length. The internode length of 1st, 5th, 6th and 7th were increased, but, 2nd, 3rd and 4th internodes were reduced. Especially the reduction of 3rd internode elongation and the increase of 5th internode length was prominent. Most of the tested cultivars showed no changes in the number of internodes elongated, but, in some cultivars it was increased and in a few ones it was reduced. The effect on the panicle length was variable depending cultivars. No significant correlation was found between the culm length elongation and the elongation of panicle length, implying that the response of GA$_3$ on the culm and on the panicle is independent of each other. According the response of culm length elongation tested cultivars were grouped into 6 ; Significantly reducing, slightly reducing, less sensitive, slightly elongating, largely elongating and extremely elongating.
