The survival or growth rate of multiple-antibiotic-resistance (Mar) mutants of Escherichia coli K-12 MC4100 or W3110, influenced by many stresses (4% ethanol, 3mM HzO, 0.5M NaC1, pH 2, pH 5, and heat-shock (42C)), and the effects of salicylate (SAL) induction were evaluated by growth rate. Under the stress conditions of pH 5 and heat-shock, growth rates of Mar mutants derived from MC4100 or W3110 induced by salicylate (SAL) were higher than those of wild type Escherichia coli K-12 and E. coli clinical isolates. Under the SAL induction, growth rates of wild type MC4100 or W3110 were higher than those of Mar mutants in case of 0.5M NaC1 or pH 2 stress, respectively. Without SAL induction, growth rates of wild type E. coli were higher than those of Mar mutants, in case of MC4100 grown with 4% ethanol, HO, or heat-shock stresses, in case of W3110 grown with pH 2, or heat-shock stress. There were sorne instances of cytotoxic effect of SAL to the Mar mutants, wild type E. coli, or E. coli clinical isolates under some stress conditions.

Multiple-antibiotic-resistance (Mar) mutants were prepared from the wild-type Escherichia coli K-12 MC4100 or W3110, were analyzed for the antibiotic resistance by minimal inhibitory concentration (MIC), and compared with their isogenic parent strains and E. coli clinical isolates. Mutation frequency was approximately 10-7 to 10-9 MIC levels of chloramphenicol (Cm), ampicillin (Ap), tetracycline (Tc), or ciprofloxacin (Cp) antibiotics against E. coli Mar mutants were 50 ug/ml, 300 ug/ml, 200 ug/ml, or 30 ug/ml, respectively, at their highest MIC levels. Cross-resistances of each Mar mutants against Cm, Ap, Tc, Cp, erythromycin (Em), nalidixic acid (Na), and rifampin (Rf) were evaluated. Almost all of Mar mutants showed approximately 9 to 140-fold increase of MIC with contrast to the MIC of isogenic parent strains and E. coli clinical isolates, except Rf antibiotics. The induction multiplicity of Mar mutants by salicylate (SAL) was approximately the same, 2 to 10-fold, and 2 to 25-fold increase of MIC, in case of E. coli clinical isolates, Mar mutants derived from MC4100, and W3110, respectively.

Diabetic Neuropathies*

To evaluate correlation between the expression of neu and ras oncoprotein and epidermal growth factor receptor on breast carcinoma and other known prognostic factors, immunohisto-chemical studies were performed. Positive reaction for neu, which appeared as brown granular deposits along cell surface and cytoplasm of the tumor cells, was significantly correlated with the histological grade but not with other prognostic factors such as tumor size, lymph node me-tastasis, local recurrence, and estrogen and progesteron receptor status. Also granular deposits of ras were noted in the carcinoma cells in the cytoplasm, while the epithelaial cells of the normal lobule and duct showed negative reation. But expression of ras was not significantly associated ras with other prognostic factors. The reaction for EGFR was mostly negative on epithelial cells of both the normal lobule and duct, and was not significantly associated with other prognostic factors. The results suggested that expression of the neu oncoprotein is significantly associated with the histological grade of breast carcinoma, while the ras and the EGFR do not show significant prognostic value.

A case of verrucous hemangiorna appearing 22-year old male as presented, The clinical lesion was wart-like and hyperkeratotic scaly plaque with satellite lesions occurring over the right side of the skin. Histopathological examination showed hyperkeratosis, papillomatosis, irregular acanthosis, and capillary hemangiomatous features in the dermis and subecutantous tissues.

Three cases of linear scleroderma with typical clinical and histopathological findings were presented. Case 1: A 10 year old female had a "coupe de sabre" type of linear scleroderma on the right side of the frontal scalp and face and hemiatrophy of the right side of the face. Case 2: A 10 year old female had a type of scleroderma en bande on the palm and dorsum of the left hand and clubbed finger of the left third finger. Case 3: A 21 year old male had a linear type of skin atrophy and sclerosis of the right lower exteremity and mild walking disturbance.
