Pulmonary agenesis is a very rare anomaly. It is defined as total absence of the pulmonary parenchyma, vascular structures, and bronchi beyond the carina. We experienced a case of right pulmonary agenesis in association with other congenital defects who died at 1 day of age. The other defects included: esophageal atresia, tracheoesophageal fistula, cardiac malformation, anal atresia and a malformed left thumb. The cardiac malformations were a type of Pentalogy of Fallot, composed of right ventricular hypertrophy, ventricular septal defect, an overiding of aorta, pulmonary atresia, and an atrial septal defect. Hand roentgenograms of the malformed left thumb showed an unarticulated metacarpopharyngeal joint. This unique combination of anomalies is extremely rare.

In order to investigate the mechanism of antibacterial effect of electrical stimulation on bone and joint infection, 5, 50 and 500 µA constant currents were passed through the silver electrodes and stainless electrodes on the Brain Heart Infusion agar culture plates which contained Staphylococcus aureus, Pseudomonas aeruginosa, and Lscherichia coli. After 24 hours of incubation, the widths of inhibitory zone around the electrodes were measured. The broth dilution susceptibility test was also used to verify the antibacterial effects of electrically generated silver in the Brain Heart Infusion broth. The results were as follows. 1. Silver anodes using constant currents manifested antibacterial effects definitely on the three bacterias, but stainless anodes showed none. 2. Antibacterial effects of silver anodes on the three bacterias increased in proportion to current density. However, antibacterial effects were negligible when current density was under 2 nA/mm2. 3. When current density was between 6.6 and 660 nA/mm2, there were no statistically significant differences in the antibacterial effects among 5, 50 and 500µA constant currents. 4. The culture broth containing silver ions generated by constant current electrolysis also manifested antibacterial effects. The retentate showed stronger antibacterial effects than the filtrate. Form these results, following conclusions were drawh. 1. The antibacterial eff ct of silver electrode using constant current was due to silver ions rather than electricity itself. 2. The substance which showed most effective antibactericity effects was silver complex larger than 2,000 m.w. and heat-unstable.

Tumoral calcinosis was coined by Inclan in 1943 and thereafter about 40 cases have been reported in the literature, but there has not been reported on a case which involved knee joints. The majority of cases hitherto reported were found in Negro. There was no report in yellow race. Authors presented a case of tumoral calcinosis that involved boih knee joints of a 55 years old Korean housewife. On physical examination chronic draining sinuses with spontaneous extrusion of calcific material was noted on the left infrapatellar region. A radiograph of the both knees showed dense, multinodular deposits of calcium. The masses were confined to the soft tissues; the contiguous joint showed no pathological change. En-block excisianal biopsy was done. The histological section of the excised mass disclosed the foreign-body giant cell with inflamed connective tissue surrounding calcific deposits.

PURPOSE: Ion channels play key roles in determining smooth muscle tone by setting the membrane potential and allowing Ca2+ influx. Potassium channels may be important in modulating corporal smooth muscle tone. In this study, we investigated the effects of potassium channels in the rabbit corpus cavernosal smooth muscle by blocking them with various agents. MATERIALS AND METHODS: Strips of rabbit corpus cavernosum were prepared for mounting and isometric tension measurement in an organ bath. On cavernosal strips contracted with phenylephrine (PHE), sodium nitroprusside (SNP) was applied in increasing concentrations from 10(-7)M to 10(-4)M, causing dose-dependent relaxation. The effects of various potassium channel blockers on SNP-induced relaxation were then evaluated by measuring the tension of the cavernosal strips. The potassium channel blockers used were tetraethyl ammonium (TEA), charybdotoxin, gliben clamide, and apamin. RESULTS: The relaxation responses to SNP of the corporal preparations contracted in response to PHE were significantly attenuated by TEA (10(-2)M) and charybdotoxin (10(-7)M), with no significant difference observed between the two drugs. The SNP-induced relaxation responses were not significantly attenuated by glibenclamide (10(-5)M) or apamin (10(-5)M). CONCLUSIONS: These results suggest that maxi-K+ channels play an important role in corpus cavernosal relaxation. The KATP channel and small-conductance KCa channel are thought to be unrelated to corpus cavernosal smooth muscle relaxation.
