Prurigo pigmentosa(PP) is a rare dermatosis with an unknown cause characterized by intensely pruritic papules that resolve with reticulate pigmentation. It is a disease entitity commonly reported in Japan but seemingly rare in other parts of the world. We report 5 cases that clinically and histopathologically fulfilled the characterisitics of PP and were treated with dapsone resulting in significant clinical improvement.

OBJECTIVES: To investigate the correlation of the initial Computerized Tomography(CT) findings of the brain and the functional outcome, and to suggest the initial CT findings as a functional outcome predictor in the traumatic brain injured(TBI) patients. METHODS: Thirty-nine TBI patients were included in this study. Subjects were divided into groups of non-focal or focal TBI, and with or without a depressed skull fracture according to their initial brain CT findings. RESULTS: The non-focal TBI patients were not significantly different from focal TBI patients in the days from onset to rehabilitation, rehabilitation stay, and initial FIM score. However their outcome in FIM gain and FIM efficiency significantly worse than focal TBI patients. The TBI patients with a depressed skull fracture were not significantly different from the patients without a depressed skull fracture in the days from onset to rehabilitation, rehabilitation stay, and intial FIM score. However their outcomes were significantly worse than patients without a depressed skull fractrue in FIM efficiency. CONCLUSION: The initial brain CT findings were generally useful for the prediction of functional outcomes in TBI patients.

BACKGROUND: Both PCNA and Ki-67 have been used as marker for cellular proliferation. The drawback of Ki-67 antibody in immunohistochemistry was that it can be labelled only on fresh tissue, however, MIB1 is a newly developed Ki-67 antiboc which can be labelled on formalin-fixed tissue. OBJECTIVE: The purpase of the present study is to compir the stainability of the Ki-67 antibody with that of the ICNA antibody on formalin-fixed, para fin embedded tissues. METHODS: Using MIE1, the newly developed Ki-67 antibody and PC10(PCNA antibody), speci mens of squamous cell carcinoma(SCC), Bowens disease(BL), actinic keratosis(AK) and basal cell epithelioma(BCE) were stained by one hour immunocytial, mistry using a Microprobe immuno/DNA stainer. RESULTS: The labelling indices (LI) of MIB1 were 82.6%, 37.4%, 38.3% & 81.1% respectively in SCC, BD, AK & BC, while the LI of PC10 were 77.69%, 26.6% & 64.4%. The labelled cells of both antibodies differed in distribution patterns on turmor tissues. CONCLUSION: MIBI cain be used to be an alternative m.rl r for proliferating cells. MIBI PC10, when used together, will be mutually compensatory the study of proliferating cell kinetics.

Ceftizoxime sodium is a new synthetic β-lactam antibiotic combining potent antibacterial activity with high stability to a wide range of bacterial β-lactamase. This experiment was achieved to evaluate the antibacterial activities of ceftizoxime sodium against. Gram negative enteric bacteria isolated from in outpatient visiting Yeungnam university hospital and to study the emergence of drug induced bacterial variants which resist to ceftizoxime in vitro. The antibacterial activity of the ceftizoxime was compared with that of antibiotics and its effect on population of normal intestinal flora in mice was observed. The results are summarized as follows: 1. Highly effective antibacterial activity of ceftizoxime against Gram negative enteric bacilli was demonstrated and this antibacterial activity was superior to that of ampicillin. 2. Several test strains shows multiple antibiotic resistance. Among 15 strains of Escherichia coli, 1 strain was resistant to ampicillin, cefadroxil, gentamicin, tetracycline, and 2 strains were resistant to ampicillin, cefadroxil, tetracycline, five strains of Escherichia coli and Enterobacter cloacae was resistant to ampicillin, tetracycline and Shigella dysenteriae was resistant to ampicillin, gentamicin, tetracycline. 3. The frequency of in vitro emergence of resistant variants among ceftizoxime sensitive bacteria in the presence of increasing concentrations of the compound was found to be low. 4. Plasmid was isolated in 6 of 9 strains (6 strains of Escherichia coli, Shigella dysenteriae, Enterobacter cloacae and Salmonella typhi). That showed different antibiotic resistance. They were 5 strains of Escherichia coli and 1 strain of Shigella dysenteriae. However, plasmid could not be considered as a hallmark for antibiotic resistance by this Further studies with curing experiment are to be accomplished for this purpose. 5. Changes in the bacterial count of normal intestinal flora following 25 mg/kg/day administration of ceftizoxime over 5 consecutive days were not significant. In conclusion, ceftizoxime appeared to be a drug of choice in the treatment of Gram negative enteric bacilli infection.

In 10 cases with intracranial arterivenous malformation (AVMs) diagnosed by MR spin echo images, MR angiography was evaluated and compared with conventional angiography in regard to depiction of nidus, arterial feeders, and draining veins. Spin echo images demonstrated the nidus of the AVM in all cases, but displayed the feeding vassels inadequately. These vessels were directly visualized with 3 dimensional STAGE(small tip angle gradient echo) MR angiography using rephasing/dephasing pulse sequences. In 5 cases MR angiography and conventional angiography showed the same results. However, in the others, MR angiography showed lower resolution than conventional angiography. MR angiography is useful in preangiographic evaluation of intracranial AVM but improvement in image resolution, which is dependent on MR hard ware and pulse sequence, is still to be desired.
