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.

The rabbit cornea was studied in vitro in modified Ussing chambers to determine the effects of ion transport inhibitors and hydrogen peroxide(H2O2) on ion transport through the cornea by measuring the bioelectric properties. Apical(tear side, T side) addition of furosemide, bumetanide and SITS were ineffective on resting Isc(short circuit current). Apical addition of 1.0mM amiloride(Na+/H+ antiport inhibitor) and NPAA(Cl- channel blocker) markedly reduced the resting Isc, but basolateral(stromal side, S side) addition of amiloride was ineffective. The site of action of these agents was the apical membrane. H2O2, an oxygen free radical, markedly increased the lsc when was added to the T side, but S side addition of the H2O2 was ineffective. To determine the degree of cellular catalase participation in protection against H2O2 induced injury the cornea was pretreated with ATAZ for 30 min prior to H2O2 action. The increase of lsc by H2O2 was markedly potentiated after pretreatment with ATAZ on T side compared to that of S side addition. This result indicates that the corneal endothelial H2O2 may be largely degraded by catalase. When H2O2 was added to the T side, Isc was raised by increased ion transport. All ion transport inhibitors that were used inhibited the H2O2 effect on Isc. Moreover, amiloride and NPAA markedly inhibited induced lsc by H2O2. These results suggest that H2O2 stimulates the corneal epithelial ion transport and that its site of action is apical membrane Na+/H+ antiport system and CI- channel system.

We have studied the dosimetric properties of electron beam using Lyon intraoperative device for intraoperative radiation therapy. The dosimetry data had compiled in such a way that a quick and correct decision regarding the cone shape, energy, and accurate calculations could be made. Using 3 dimensional water phantom, we have got the following data: cone output ratios, surface dose, dmax, dgo, flatness, symmetry, beam profiles, isodose curve, and SSD correction factors. The cone output ratios were measured with straight and bevelled cone, respectively. As the cone size and the energy were reduced, the cone output ratios decreased rapidly. With the flattening filter, the surface dose increased by electron beam to 85.3%, 89.2%, and 93.4%, for 6MeV, 9MeV, and 12MeV, respectively. It is important to increase the surface dose to 90% or more. Inspite of diminishing dose rate and beam penetration, this flattening filter increases the treatment volume significantly. With the combination of the three levels collimation and the flattening filter, we achieved good homogeneity of the beam and better flatness and the diameter of the 90% isodose curve was increased. It is important to increase the area that is included in the 90% isodose level. The value of measured and calculated SSD correction factors did not agree over the clinically important range from 100cm to 110cm .

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.

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.
