Development of supervoltage treatment machine may minimize skin reaction by skin-sparing effect, but skin damage is still one of “the dose limiting factor” in radiation therapy. In spite of these importance, systemic histopathologic studies of skin in similar conditions which used in clinical treatment has not been performed so far. 60 mice were irradiated with conventional fraction (200x5/wk) and whole abdominal field (2x3 cm, from symphysis pubis to xyphoid process). Used machine was 250 KV, 24 mA. orthovoltage x-ray machine. Histopathological changes of acute skin reaction at the level of total irradiation dose were analyzed and possible mechanism of later chronic changes were investigated. Obtained results are as follows 1. In 1,000 rad irradiated group, only mild epidermal edema is noted. 2. In 2,000 rad irradiated group, slightly decreased number and size of hair follicles and appendages, dermal edema and scanty infiltration of inflammatory cells are visible. 3. In 3,000 rad irradiated group, marked increased capillary congestion and prominent infiltration of inflammatory cells are observed. 4. In 4,000 rad irradiated group, vascular wall thickening with proliferation of endothelial cells are prominent. Dermal thinning and hyalinization are newly developed. 5. In 5,000 rad irradiated group, complete desquamation of epidermis is not seen, despite of acceleration of all above mentioned changes.

In this study, we are to produce the single chain variable fragment (scFv) antibodies against surface protein of hepatitis B virus (HBV) using antibody phage display technique. Balb/c mice were immunized with preS1 and cDNAs of heavy and light chains of splenic B cells from immunized mice were prepared using RT-PCR. Two cDNAs were linked with (64S) linker DNA under recombination PCR to produce single chain Fv DNA. After digestion of scFv DNA with Sp 1 and Not 1, the digested DNA was ligated into pCANTAB 5E and electroporated into E. coli XL1-Blue to prepare scFv-library. The size of library was 1 * 10' pfu/ml. Phage antibodies (phabs) against preS1 were rescued with M13K07 helper phages, and preS1-binders were selected through 3 times of panning using 96 well microtitre plates. Phage antibody clones were assayed directly for the ability to bind preS1 by ELISA. And then 7 phage antibody clones had high ELISA signals against preS1. Phabs from preS1-specific pMsc-17 had the strongest ELISA signal to preS1. Phabs from pMsc-17 were used for Western blot to preS1 and the results revealed that it was specific to preS1. To prepare the soluble scFv antibody, phabs from pMsc-17 were transfected into non-suppressor E. coli HB2151, and grown under 1 mM IPTG. Soluble scFv antibody was mainly accumulated in the periplasmic space, but small amount of antibody was secreted into culture media.

We present a case of left ectopic ureteral orifice to the vagina with a hypoplastic kidney in a 15 year old girl and a case of ectopic ureteral orifice to the vaginal vestibule associated with bilateral complete double ureter in a 5 year old girl. They presented with urinary incontinence while normally secured voluntary voiding. Fifteen year old girl was treated with left nephrectomy and the other girl with heminephrectomy.

The urinary flow rates of 917 children between 7 years and 15 years old were measures. The results were as follows . 1. Volume voided, average and maximum flow rate were higher according to increasement of age and sex. All values of female children were significantly higher than male children in same age and body Weight. 2. Voiding curves indicating the relationship between urinary flow and voided volume were obtained with logarithmic transformation. Voiding dates above 35kg were significantly higher than below 35kg and were similar to normal adults. 3. Fifth 10th, 15th, 20th and 25th percentiles nomograms were established with cumulative distribution.
