From August to November 1985 244 bacteriologically proven male uncomplirated goncicoccal urethritis patients at the VD clinic of Choong-Ku Public Health Center form August to November 1985 were divided into group A and group B according to a random number sheet. In group A, treated with kanamycin 2.Ogm, im plus benzyl penicillin-G 5 mega units, im plus probenecid, 1.Ogm, PO; 112 of 121 patients were followed and 10 patients (8.9%) failed to be recovered. In group B, treated with kanamycin, 2,Ogm, im plus trimethoprim-sulfamethoxazole, 9 tahlets, PO; 112 of l23 patients were followed and 7(6.3%) failed. There is no sign.ificant difference between the two groups (p>0. 05) The failure rates in PPNG urethritis were 14.3% and 8.0% in group A and group B respectively. There is a signficant difference in failure rate between the two groups (P<0.05). It is suggested that, because of high rate of PPNG among circulating N.gonorrhoeae, the combinatioin regimen of kanamycin and trime.thoprim-sulfamethoxazole may be used as a first line treatrnent regimen for uncomplicated gonococcal urethritis.

Bactrim consists of the sulfonamides trimethoprim and sulfamethoxazole. These induce relatively frequent adverse drug reactions, including allergic reactions ranging from urticaria to anaphylaxis. Either component can be the causative allergen, so it is necessary to determine which has caused an allergic reaction to prevent further allergy. We report the case of a 46-year-old male with chronic renal failure who experienced anaphylactic shock twice after ingesting trimethoprim-sulfamethoxazole, as was proven by the medical history and skin prick testing. Enzyme-linked immunoassays and enzyme-linked allergen inhibition assays for allergen-specific IgE antibody for the five components of Bactrim showed that sulfamethoxazole was the causative allergen.

A 72-year-old female with 10% TBSA flame, mostly partial thickness, was treated topically with 10% mafenide acetate cream and 1% silver sulfadiazine cream. On day 28, burn wound was nearly healed but black colored, 3~5 mm sized maculopapular lesions developed in healed facial burn wound. Similar skin lesion progressed in both hand and both wrist. All skin lesions were peeled off. On day 30, biopsy was performed. An excisional biopsy of the lesion in the left cheek revealed benign papilloma. On day 44, we excised all skin lesions and performed STSG. All graft sites were healed 14th day after STSG.

OBJECTIVES: We tested the possibility of differential expression and function of the potassium-chloride (KCC2) and sodium-potassium-2 chloride (NKCC1) co-transporters in the lateral superior olive (LSO) of heterozygous (+/cir) or homozygous (cir/cir) mice. METHODS: Mice pups aged from postnatal (P) day 9 to 16 were used. Tails from mice were cut for DNA typing. For Immunohistochemical analysis, rabbit polyclonal anti-KCC2 or rabbit polyclonal anti-NKCC1 was used and the density of immunolabelings was evaluated using the NIH image program. For functional analysis, whole cell voltage clamp technique was used in brain stem slices and the changes of reversal potentials were evaluated at various membrane potentials. RESULTS: Immunohistochemical analysis revealed both KCC2 and NKCC1 immunoreactivities were more prominent in heterozygous (+/cir) than homozygous (cir/cir) mice on P day 16. In P9-P12 heterozygous (+/cir) mice, the reversal potential (Egly) of glycine-induced currents was shifted to a more negative potential by 50 microM bumetanide, a known NKCC1 blocker, and the negatively shifted Egly was restored by additional application of 1 mM furosemide, a KCC2 blocker (-58.9+/-2.6 mV to -66.0+/-1.5 mV [bumetanide], -66.0+/-1.5 mV to -59.8+/-2.8 mV [furosemide+bumetanide], n=11). However, only bumetanide was weakly, but significantly effective (-60.1+/-2.9 mV to -62.7+/-2.6 mV [bumetanide], -62.7+/-2.6 mV to -62.1+/-2.5 mV [furosemide+bumetanide], n=7) in P9-P12 homozygous (cir/cir) mice. CONCLUSION: The less prominent immunoreactivities and weak or absent responses to bumetanide or furosemide suggest impaired function or delayed development of both transporters in homozygous (cir/cir) mice.

PURPOSE: To design and test the CT simulator phantom for geometrical test. MATERIAL AND METHODS: The PMMA phantom was designed as a cylinder which is 20 cm in diameter and 24 cm in length, along with a 25x25x31 cm3 rectangular parallelepiped. Radio-opaque wires of which diameter is 0.8 mm are attached on the other surface of the phantom as a spiral. The rectangular phantom was made of four 24x24x0.5 cm3 square plates and each plate had a 24x24 cm2, 12x12 cm2, 6x6 cm2 square line. The squares were placed to face the cylinder at angles 0degrees, 15degrees, 30degrees, respectively. The rectangular phantom made it possible to measure the field size, couch angle, the collimator angle, the isocenter shift and the SSD, the measurements of the gantry angle from the cylindrical part. A virtual simulation software, AcQSimTM, offered various conditions to perform virtual simulations and these results were used to perform the geometrical quality assurance of CT simulator. RESULTS: A 0.3~0.5 mm difference was found on the 24 cm field size which was created with the DRR measurements obtained by scanning of the rectangular phantom. The isocenter shift, the collimator rotation, the couch rotation, and the gantry rotation test showed 0.5~1 mm, 0.5~1degrees0.5~1degrees, and 0.5~ 1degreesdifferences, respectively. We could not find any significant differences between the results from the two scanning methods. CONCLUSION: The geometrical test phantom developed in the study showed less than 1 mm (or 1degrees) differences. The phantom could be used as a routine geometrical QC/QA tools, since the differences are within clinically acceptable ranges.

The 4 bank mico-MLC (mMLC; Acculeaf, Direx, Isral) has been commissioned for clinical use of linac based stereotactic radiosurgery. The geometrical parameters to control the leaves were determined and comparisons between measured and calculated by the calculation model were performed in terms of absolute dose (cGy/100 MU). As a result of evaluating calculated dose for various field sizes and depths of 5 and 10 cm in water in the geometric condition of fixed SSD (source to surface distance) and fixed SCD (source to chamber distance), most of differences were within 1% for 6 MV and 15 MV x-rays. The penumbral widths at the isocenter were approximately evaluated to 0.29~0.43 cm depending on the field size for 6 MV and 0.36~0.51 cm for 15 MV x-rays. The average transmission and leakage for 6 MV and 15 MV x-rays were 6.6% and 7.4% respectively in single level of leaves fully closed. In case of dual level of leaves fully closed the measured transmission is approximately 0.5% for both 6 MV and 15 MV x-rays. Through the commissiong procedure we could verify the dose characteristics of mMLC and approximately evaluate the error ranges for treatment planning system.

PURPOSE: LiF TLD has a problem to be used in vivo dosimetry because of the toxic property of LiF. The aim of this study is to develop new dosimeter with LiF TLD to be used in vivo dosimetry. MATERIALS AND METHODS: We designed and manufactured the teflon box(here after TLD holder) to put TLD in. The external size of TLD holder is 4x4x1 mm3. To estimate the effect of TLD holder on TLD response for radiation, the linearity of TLD response to nominal dose were measured for TLD in TLD holder. Measurement were performed in the 10 MV x-ray beam with LiF TLD using a solid water phantom at SSD of 100 cm. Percent Depth Dose (PDD) and Tissue-Maximum Ratio (TMR) with varying phantom thickness on TLD were measured to find the effect of TLD holder on the dose coefficient used for dose calculation in radiation therapy. RESULTS: The linearity of response of TLD in TLD holder to the nominal dose was improved than TLD only used as dosimeter. And in various measurement conditions, it makes a marginnal difference between TLD in TLD holder and TLD only in their responses. CONCLUSION: It was proven that the TLD in TLD holder as a new dosimetry could be used in vivo dosimetry.

In order to evaluate the radio-protective advantage of an enhanced dynamic wedge (EDW) over a physical wedge (PW), we measured peripheral doses scattered from both types of wedges using a 2D array of ion-chambers. A 2D array of ion-chambers was used for this purpose. In order to confirm the accuracy of the device, we first compared measured profiles of open fields with the profiles calculated by our commissioned treatment planning system. Then, we measured peripheral doses for the wedge angles of 15 degrees, 30 degrees, 45 degrees, and 60 degrees at source to surface distances (SSD) of 80 cm and 90 cm. The measured points were located at 0.5 cm depth from 1 cm to 5 cm outside of the field edge. In addition, the measurements were repeated by using thermoluminescence dosimeters (TLD). The peripheral doses of EDW were (1.4% to 11.9%) lower than those of PW (2.5% to 12.4%). At 15 MV energy, the average peripheral doses of both wedges were 2.9% higher than those at 6MV energy. At a small SSD (80 cm vs. 90 cm), peripheral dose differences were more recognizable. The average peripheral doses to the heel direction were 0.9% lower than those to the toe direction. The results from the TLD measurements confirmed these findings with similar tendency. Dynamic wedges can reduce unnecessary scattered doses to normal tissues outside of the field edge in many clinical situations. Such an advantage is more profound in the treatment of steeper wedge angles, and shorter SSD.
