The histochemical study, especially the demonstration of alkaline phosphatase and acid phosphatase was carried out in order to differentiate ascarides of human and pigs. The experimental material were obtained from naturally contaminated men and pigs. As the histochemical staining methods the Gomori's was applied for acid phosphatase and Takeuchi and Takami's for alkaline phosphatase. The results obtained were summerized as follows : In the pig's ascarides, alkaline phosphatase was richly found in the subcuticular tissue, lateral line, median line, strial zone and epithelial cells of the intestine, epithelial cell and basal membrane of the ovary, the same part of the uterus and also in eggs. Acid phosphatase in the pig's ascarides were distributed in the same part as alkaline phosphatase. It, however, was darker brown in the soft tissue of the lateral line, epithelium of excretory canal, median bundle, whole zone of the intestine and intestinal contents. In the human ascarides, the alkaline phosphatase was distributed in the testes and the parts where the acid phosphatase was found in the pig ascarides. The acid phosphatase in the human ascarides was demonstrated in the subcuticular tissue, soft tissue of lateral line, epithelium of excretory cells, strial zone, transparent zone, granular zone and epithelial zone of esophagus and intestine, ovary, ova in the uterus, epithelial cell and basal membrane of the uterus and in testes. In the pig's ascarides, the area of distribution of alkaline phosphatase was restricted, but that of acid phosphatase was wider. In human ascarides, the area of distribution of alkaline phosphatase and acid phosphatase was not significantly different, but in some part showed slight difference. Above mentioned finding suggest that the distribution of phosphatase could be utilized for the differentiation of ascarides of human and pig.

We present herein 3 cases of early secondary syphilis with simultaneous primary syphilitic lesions. These cases developed primary syphilitic lesions four to six weeks after sexual contact and lasted six to ten weeks thereafter until the secondary syphilitic lesions appeared. All three patients showed a strong positive for the STS. Spirochetes were seen under dark field examination of the primary syphilitic lesions, Histopathologically, numerous plasma cells around capillaries and endothelial hyperplasia were seen in the dermis.

All-ceramic restorations have become an attractive alternative to porcelain-fused-to-metal crowns. In-Ceram, and more recently IPS Empress 2 were introduced as a new all-ceramic system for single crowns and 3-unit fixed partial dentures. But their strength and marginal fit are still an important issue. This study evaluated the fracture resistance and marginal fit of three systems of 3 unit all-ceramic bridge fabricated on prepared maxillary anterior resin teeth in vitro. The 3 all-ceramic bridge systems were: (1) a glass-infiltrated, sintered alumina system (In-Ceram) fabricated conventionally, (2) the same system with copy-milled alumina cores (copy-milled In-Ceram), (3) a heat pressed, lithium disilicate reinforced glass-ceramic system (IPS Empress 2). Ten bridges of each system with standardized design of framework were fabricated. All specimens of each system were compressed at 55degree at the palatal surface of pontic until catastrophic fracture occurred. Another seven bridges of each system were fabricated with standard method. All of the bridge-die complexes were embedded in epoxy resin and sectioned buccolingually and mesiodistally. The absolute marginal discrepancy was measured with stereomicroscope at x50 power. The following results were obtained: 1. There was no significant difference in the fracture strength among the 3 systems studied. 2. The Weibull modulus of copy-milled In-Ceram was higher than that of In-Ceram and IPS Empress 2 bridges. 3. Copy-milled In-Ceram (112micrometer) exhibited significantly greater marginal discrepancy than In-Ceram (97micrometer), and IPS Empress 2 (94micrometer at P=0.05. 4. The lingual surfaces of the ceramic crowns showed smaller marginal discrepancies than mesial and distal points. There was no significant difference between teeth (incisor, canine) at P=0.05. 5. All-ceramic bridges of three systems appeared to exhibit sufficient initial strength and acceptable marginal fit values to allow clinical application.
