Gastric cancer cells express large amounts of galectin-3 on the cell surface. This fact may provide the possibility to use galectin-3 protein as a surface target for delivering cytotoxic anticancer agents. To investigate the possibility of application of galectin-3 protein as a target protein in delivering cytotoxic anticancer agents, we synthesized doxorubicin immunoconjugate by using maleimidocaproic acid and conjugated doxorubicin immunoconjugate to anti-galectin-3 mAb. The anticancer effect of immunotoxin was assayed on NIH3T3, AGS and KATO III cell lines. The anticancer effect of immunotoxin on AGS cell line is highest and that of KATO III is higher than that of NIH3T3. This results relate to that of flow cytometry analysis previously shown and indicate that galectin-3 protein can be used as a target protein on the surface of gastric cancer cell for delivering cytotoxic anticancer agents.

It is believed that the photopatch test is a valuable screening procedure for the determination of responsible antigenic substances in photoallergic contact dermatitis. But the technigues used for this procedure are cumbersome and require expensive equipment. In the present study, we adapted an easy and inexpensive photopatch test met- hod to our need. We report the results of this test method which was performed. in 21 patients with photodermatitis and 9 patients with polymorphic light eruption. 1. The UVB sensitivity determined by minimal erytherna dose (mean+-standard deviation) was I1618mW sec/cm in photodermatitis group, 108+ROmW sec/cm in polymorphic light eruption group and 126-+32mW-sec/cm in control group. But there was no significant difference among them (p>0. 05). 2. The reaction to UVA were negative in all groups. R. The photopatch test using IO potential photosensitizers revealed 12 positive responses in 9 patients; including 7 patients in photodermatitis group and 2 patients in polymorphic light eruption group. And the number of positive photopatch responses obtaied with each photosensitizer in RO patients with photodermatoses was 5 in chlorhexidine, 2 in paraaminobenzoic acid, musk ambrette and bithionol and 1 in chlorpromazine, respectively.

Botulium toxin A has been used therapeutically in humans for over 20 years for a variety of medical indications. Some wrinkle and unsightly facial expressions are due to hyperkinetic muscle. For the past year, the author has injected it for variant purpose, so we describe the our experience with the variant extended use of the toxin including correction for just dynamic wrinkle, used with subperiosteal face lifting or peeling, post-traumatic twitching, and facial paralysis and relevant anatomy are discussed. Also we have another concept about muscle anatomy which have superficial and deep portion. The superficial portion is for harmonious action with SMAS during facial expression, which is also related to fine wrinkle, and the deep portion play role gross movement. Botulium toxin is safe and effective in varient field without complication. Its use is associated with a high degree of patient and physician satisfaction.

BACKGROUND: Renal dysplasia is the abnormal development of the kidney. The condition is usually detected in childhood along with other urinary tract anomalies, but can remain unnoticed until adulthood. It was recently reported that a PAX2 gene mutation plays a major role in the development of renal dysplasia. The aim of this study was to examine the expression of PAX2 in dysplastic kidneys of children and adults. METHODS: A total of 30 cases diagnosed with renal dysplasia after a nephrectomy were examined. PAX2 expression was evaluated using immunohistochemistry. Apoptosis was detected using an Apop Tag detection kit. RESULTS: In the dysplastic kidneys, there was strong PAX2 expression in the epithelia of the primitive ducts in both children and adults, but the degree was significantly lower in adults (p=0.007). However, the mesenchyme surrounding the primitive ducts of children showed stronger staining for the smooth muscle actin antibody and trichrome than the adults. The apoptosis index was significantly higher in the primitive duct epithelia than in the surrounding normal collecting duct epithelia (p=0.000). CONCLUSIONS: PAX2 is overexpressed in the primitive ducts of renal dysplasia, which is sustained until adulthood and is associated with increased apoptosis. However, a decrease in PAX2 expression in the dysplastic epithelia and mesenchymal cuff of adults suggest a gradual regression of the dysplastic elements with time.

BACKGROUND: During the adolescent growths spurt, iron deficiency becomes more common, particularly with the additional factors of menstrual blood loss in females and the androgen-related rise in hemoglobin concentration in males. This study was conducted to investigate the iron status in the adolescent students. METHODS: Venous peripheral blood was sampled from 178 males(79 of 12-13years, 99 of 15-16years) who were 1st grade students of two boy's middle schools and two high schools and from 186 females(87 of 12-13years, 99 of 15-16years) who were 1st grade students of two girl's middle schools and two high schools. Laboratory procedures included a hemoglobin, hematocrit, serum iron, TIBC and serum ferritin. Transferrln saturation was calculated. RESULTS: 1) Mean values were hemoglobin 13.7+/-0.78 g/dl, hematocrit 40.6+/-2.47%, serum iron 127.6+/-43.02 ug/dl, TIBC 387.9+/-47.73 ug/dl, transferrin saturation 33.3+/-11.38%, and serum ferritin 26.1+/-16.90 ng/ml in 12-13years old males. 2) Mean values were hemoglobin 13.7+/-0.85 g/dl, hematocrit 40.9+/-3.79%, serum iron 99.4+/-34.93 ug/dl, TIBC 387.8+/-45.53 ug/dl, transferrin saturation 26.2+/-9.99%, and serum ferritin in 22.7+/-14.18 ng/ml in 12-13years old females. 3) Mean values were hemoglobin 15.2+/-0.84 g/dl, hematocrit 45.9+/-2.77%, serum iron 144.9+/-51.97 ug/dl, TIBC 419.8+/-52.46 ug/dl, transferrin saturation 34.2+/-10.44%, and serum ferritin 31.2+/-20.91 ng/dl in 15-16years old males. 4) Mean values were hemoglobin 13.2+/-0.89 g/dl, hematocrit 39.9+/-2.78%, serum iron 111.1+/-39.78 ug/dl, TIBC 392.8+/-50.06 ug/dl, transferrin saturation 28.9+/-10.85%, and serum ferritin 21.4+/-17.11 ng/ml in 15-16years old females. 5) The prevalence of iron deficiency was 8.9% and 10.1% in 12-13years and 15-16years old males respectively. In 12-13years and 15-16years old females, the prevalence was 16.1% and 29.3% respectively. The prevalence of iron deficincy anemia was 1.1% and 2.0% in 12-13years and 15-16years old female and absent in male. CONCLUSIONS: Although hemoglobin is normal, we recommend to check other parameters to optimize the identification of individuals with iron deficiency.

Clinical observation was made on 11 cases of ureterosigmoidostomy during the period from 1959 to 1976. Age ranged from 27 to 65 years and 7 female and 4 male each. Underlying diseases at the time of operation were 6 cases of vesico-vaginal fistula and 5 cases of bladder tumor. Their operation time, amount of transfusion, electrolyte balance, early and late complications after operation were analyzed. It seemed to us that despite the many urologist abandon ureterosigmoidostomy and prefer ileal diversion, its usefulness is assessed in our paper and applicable to some selected patients.

A clinical study was carried out on 206 glaucomatous patients(295 eyes) from July 1982 to December 1985 in the Department of Ophthalmology of Hanyang University Hospital. The results were as follows: 1. The glaucomatous patients consisted of 34.0% of primary open angle glaucoma(P.O.A.G.), 32.5% of secondary glaucoma, 20.9% of primary angle closure glaucoma(P.A.C.G.), 73% of ocular hypertension, 3.9% of congenital glaucoma and 1.5% of low tension glaucoma. 2. The mean intraocular pressure(IOP) of P.O.A.G. and acute stage of P.A.C.G. was 33.4 +/- 15.5 and 55.2 +/- 8.4mmHg, respectively. 3. 43.1 +/- 16.3 years was the mean age of P.O.A.G. and 61.6 +/- 9.5 years was that of P.A.C.G. 4. In overall glaucomatous patients there was no remarkable sex-difference except P.A.C.G. which showed higher prepondrence of females. 5. There was no significant difference in laterality between left and right eyes with glaucoma or ocular hypertension.

A 19-year-old man noticed a very slowly spreading erythematous macular lesion on his cheek when he was 5 years old. This asymptomatic and well circumscribed patch was covered with fine scales. He sought first medical attention at the age of 12 years and diagnosis was cutaneous tuberculosis was made by skin biopsy. Seven years after the second biopsy was made and it revealed a few spores within giant cells in the upper dermis. By mycologic study, it was identified as Paecilomyces lilacinus. The patient was put on the treatment of topical and oral antifungal agents. The skin lesion showed signs of improvement after 12 weeks of treatment.
