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.

Both spindle cell variant of squamous cell carcinoma and atypical fibroxanthoma are most commonly presented as a solitary, often ulcerated nodule, occurring on sun-exposed skin of the elderly. These lesions also share the histologic features of diffuse or indistinct fascicular arrangement of polygonal or pulmp spindle cells. Therefore it is not easy to differentiate immunohistochemistry is done. A case of 73 year old woman with squamous cell carcinoma of the skin resembling atypical fibroxanthoma is presented.

Interferons(IFNs) exhibit an antiproliferative effect on many normal and transformed cells and have in vivo antitumor activity in a variety of cancers. Recent clinical studies have suggested major activity with IFNs, especially in advanced squamous cell carcinoma of the skin and cervix. With the objective of exploring how the IFNs might work in squamous carcinoma cell line, we studied the effect of IFN-a on cervical cancer cell lines. The effect of IFNs on apoptosis and cell cycle of cervical cancer cell lines(C33A, CaSki, SiHa, HeLa, ME-180) was analysed by flow cytometry in time dependent manner. Results were as follows: (1) According to cell count of studied cancer cell lines treated with 2,000 IU/ml IFN-a for 7 days exposure, IFN-a had the antiproliferative effect on all five tested cervical cancer cell lines. Also this antiproliferative effect was confirmed by WST-1 assay. (2) The effect of IFN-a on apoptosis of each cultute was analysed by flow cytometry after 3 days and 7 days exposure with 2,000 IU/ml IFN-a, Apoptosis was not induced by IFN-a treatment. (3) The effect of IFN-a on the cell cycle of each culture was analysed by flow cytometry after 3 days exposure with 2,000 IU/ml IFN-a. As compared to control cells, treatment with IFN-a resulted in a higher proportion of cells in S phase with lower portion of cells with G2/M phase. (4) Time course of IFN-a effect on HPV 16 and HPV 18 E6 mRNA levels was evaluated by northern blot analysis. In CaSki cell line, HPV 16 E6 mRNA expression induced by IFN-a was not inhibited. But in HeLa cell line, HPV 18 E6 inRNA expression was inhibited. IFN-a appears to have the antiproliferative effect on all five tested cervical cancer cell lines and the antiproliferative effect of IFN-a seemed to be induced not by apoptosis but by disruption on specific cell cycle. Also regulation of HPV E6 mRNA expression induced by IFN-a is not directly related to the mechanisms of the antiproliferative effect of IFN-a in cancer cell lines.

In order to elucidate mechanisms of Ca++ antagonistic action of kanamycin in the biological system, the effects of kanamycin on Ca++ transport in sarcoplasmic reticulum of rabbit skeletal muscle and liver mitochondria were studied. At the same time, the effect of the agent on Bowditch and Woodworth phenomena of rabbit heart as well as the superprecipitation of actomyosin isolated from rabbit skeletal muscle were studied. Since kanamycin inhibits the Bowditch staircase phenomena in rabbit cardiac muscle, it is speculated that kanamycin inhibits Ca++ influx across the cell membrane which is required for the muscular contraction. Kanamycin also inhibits the Woodworth staircase phenomena, indicating a decrease in size of the Ca++ pool in cardiac muscle which may be brought about by an inhibition of Ca++ transport in sarcoplasmic reticulum and mitochondria. Actually, kanamycin was found to inhibit both the activities of Ca++ activated adenosine triphosphatases (ATPase) and Ca++ transport in sarcoplasmic reticulum and mitochondria. Kanamycin also inhibits both the development of superprecipitation and the activity of Ca++activated ATPase of skeletal actomyosin in rabbits. From the results obtained above, it may be concluded that kanamycin possesses a Ca++ antagonistic action in the biological system.

The authors report a caruncular abscess caused by actinomycosis. A 47-year-old woman was admitted with persistent purulent discharge from the caruncle of the left eye for a duration of six months. Excisional drainage was performed, and 'sulfur granules' were observed, consistent with actinomyces infection. Intraoperative lacrimal probing and irrigation were performed to confirm that the abscess and canaliculus were not connected. Oral and topical antibiotics were administered postoperatively; the lesion resolved with no evidence of recurrence, and the symptom improved.
