On strains of dematophytes isolated from superficial fungal infection patients, susceptibility tests were undertaken to topical antifungal agents (econazole, clotrimazole, siccanin, and tolnaftate). Minimal inhibitory concentration of the drugs was cletermined after 4 days incubation at room temperature on Sabourauds dextroes agar. Diverse susceptibility pattern was observed among different fungal species. Minor variability of susceptibilities was noted within the same species except for Trichophyton rubrum to econazole and tolnaftate in which a marked variation of susceptibilities was noted, Among drug tested, tolnaftate showed the most strong antifungal action, and Trichophyton mentagrophytes was the least sensitive species to all drugs. Minimal inhibitory concentration levels of each drug are as follows; clotrimazole was in the range of 2-8 mcg/ml., econazole was in the range of 0.06-2 mcg/rnl., siccanin was in the range of 05-2 mcg/ml., and tolnaftate was in the range of 0.01-0.25 mcg/ml.

Erythema multiforme(EM) is an acute, self-limited eruption of the skin and mucous membrane, characterized by distinctive target lesions. Although a wide range of factors have been implicated as precipitating EM, the pathogenesis is unknown. Recently, several studies on EM have been reportecl, showing the presence of immune complexes in patient with EM, and these authors suggested that such complexes may be cf immunopathogenic significance. The atudy was undertaken to irivestigate the pathogenesis of EM. In ten patients with EM, we performed serological study and direct immunofluorescence study. The reaults obtained were as follows. 1) There was no signifir.ant abnormality in CBC, urinalysis, chest PA, stool, and serology including ASO, CH, Ig quantitation, VDRL, HBsAg, ANA, RF, and cryoglobul in. 2 In direct immunofluorescence study, 4 biopsies showed IgM deposits in the su!erficial blood vessels, 4 demonstrated C, 2 showed IgG deposition and 2 biopsies showed fibrin deposition. All biopsies were negative for lgA. Additionally 1 biopsy demonstrated IgM depnsition along the dermoepidermal junction, and 1 showed both IgG and fihrin deposition. This study supports the view that deposition of immune complexes may play a role in the pathogenesis of EM.

To study the gyrA mutations of E. coli from clinical specimens, 410 strains were isolated from 1994 to 1997 in Kyungpook National Vniversity hospital. Antimicrobial susceptibility tests, PCR and sequencing of gyrA, and in vitro induction of quinolone resistance were done. The frequency of quinolone resistant E. coli strains increased constantly during 1994 through 1996. Quinolone-resistant strains were more often resistant to unrelated antibiotics than quinolone-susceptible strains (chi-square test, p<0.05). All of the randomly selected 55 quinolone- resist#ant strains were highly resistant to nalidixic acid (NAL) but had low level resistance to fluoroquinolones. All of the 55 quinolone-resistant strains showed an amino acid substitution of Ser -> Leu (TCG -> TIG) at codon 83. In addition, four different types of amino acid substitution affecting codon 87 (Asp) were detected, 1) type I: Asn (GAC -> AAC); 2) type II: Tyr (GAC -> TAC); 3) type III: Oly (GAC -> GGC); 4) type IV: His (GAC -> CAC). The mutation of type IV has not been reported previously in quinolone-resistant E. coli strains. It is thought that the specific amino acid substitution probably affects minimum inhibitory concentrations (MIC) of quinolones because the MICs of ciprofloxacin, norfloxacin, and ofloxacin in type II were significantly higher than those of type I. By in vitro induction, MICs to quinolone-susceptible strains resulted in the increase in the MICs of all quinolones tested by 2- to 2048-fold. The induced mutants by quinolones had amino acid substitutions at codon 83, SerLeu or Asp87Asn, Gly or Tyr. Alteration of Ser83 results in the most effective increase in the MIC of quinolone such as NAL and alterations of Asp87 result in the effective increase of MIC of fluoroquinolone. These results suggest that the continuous use of quinolones might induce the specific amino acid substitution at gyrA.

We report four cases of hyalinosis cutis et mucosae. They developed hosrseness in their infancy and all had past history of frequent skin infections with accompanying varioliform scars. On physical examination, all the patients had beaded papules along their eyelid margins, hoarseness, varioliform scars and various skin and mucous membrane infiltrations. Pathologic examinations performed on skin infiltrations and eyelid papules revealed diastase resistant periodic acid Schiff positive materials deposited mainly in upper dermis. We have given three of four patients 1g/day of dimethyl sulphoxide from 6 to 12 months with no significant side effects nor remarkable clinical improvement.

The study was undertaken to evaluate the heat resistance by split dose hyperthermia in various time intervaland temperature. For the experiments, 96 mice were divided into 2 groups: the first, 36 mice were used to evaluatethe skine reaction of mouse tail to single dose hyperathermia, the second, 60 mice were used to evaluate heatresistance by split dose hyperthermia in variuos time intervals. The results obtained are summarized as follows;1. The ND was 101 minutes at 43degrees centigrade(C) and 24 minutes at 45degrees C. 2. For a 1degrees C increasein temperature, a half in time was required to same degree of skin reaction. 3. Heat resistance was significantlydeveloped in split dose hyperthermia at 43degrees C and 45degrees C. 4. Development, maximum and decay of heatresistance were constant regardless of change in temperature. In summary, heat resistance in split dosehyperthermia is important in study and clinical application of heat therapy in malignant disease.

CT was found to be highly accurate in predicting tumor size and assessing invasion of the surroundingstructures and distant metastasis. Also CT played an important role for determination of operability of esophagealcarcinoma. The CT findings with barium esophagogram in 21 patients with histologically proven esophageal carciomawere reviewed from Feb. 1985 to Feb. 1986 at the department of Radiology, Yonsei University ,College of Medicine.The results were as follows: 1. Number of patients in each stages were: 2 in stage 1, 6 in stage 2, 4 in stage 3,and 9 in stage 4. 2. Peak age distribution was in its 6th decasedes as 9 patiens (42.9%). Overall mean age was 60.8 years. Number of male patients were 19 and 2 of female. 3. Histologic types of esohageal carcinoma were 19cases of epidermoid (90.5%) and 2 cases of adenocarcinoma(9.5%). 4.

The integration of artificial intelligence (AI), especially deep learning techniques, is revolutionizing obstetrics and gynecology. AI algorithms can analyze complex medical data, including imaging and genomics, to manage high-risk conditions such as placenta accreta spectrum (PAS) and to improve the outcomes of assisted reproductive technology. Despite significant advancements, challenges persist, including issues with data standardization, ethical concerns, and the complexity of implementing deep learning models.Current Concepts: Deep learning has demonstrated high sensitivity and specificity in diagnosing conditions like PAS and fetal cardiac anomalies. It optimizes embryo selection, tailors hormonal therapy, and predicts preterm birth risks using advanced tools such as CADXpert. Additionally, radiomics combined with deep learning enhances magnetic resonance imaging-based diagnosis and prognosis, particularly in endometrial cancer. However, barriers such as limited model interpretability and regulatory compliance continue to restrict widespread implementation.Discussion and Conclusion: A multidisciplinary approach involving clinicians, data scientists, and policymakers is crucial to addressing these challenges. Efforts should concentrate on developing standardized datasets, creating explainable models, and establishing robust educational frameworks. Overcoming these barriers will enable precise diagnoses and personalized treatments, ultimately improving patient care and outcomes in obstetrics and gynecology.
