Cyanide poisoning is expected to be antagonized by the administration of oxygen, when it is administered in combination with the conventional cyanide antidote, sodium,thiosulfate. However, the antidotal efficacy and its exact mechanism of oxygen in cyanide poisoning is still a controversial one. To test the effect of oxygen on the antidotal action of thiosulfate ,in cyanide poisoning, author designed this study on the dose-mortality patterns for potassium cyanide in mice. Potency ratios derived from LDso values were compared in groups of mice treated with sodium thiosulfate alone and sodium thiosulfate with oxygen. These results indicated that oxygen enhances the anti-dotal effect of sodium thiosulfate, effectively. This fact demonstrates that oxygen is of importance in the treatment of cyanide poisoning.

This study was designed to assess the effects of compound madecassol(madecassic acid with neomycin sulfate and hydrocortisone acetate) on the wound healing. Madecassol is a titrated extract of centella asiatica and the clinical effects of madecassol are stated to the enhancement of wound healing and the prevention and relief of excessive scar formation. Compound madecassol is composed of madecassol and neomycin sulfate and hydrocortisone acetate. Neomycin sulfate has antibiotic effect and hydrocortisone acetate has antiinflammatory and antiallergic effects. So, compound madecassol has a synergistic effect of madecassol as well as neomycin sulfate and hydrocortisone acetate. Using 54 rats, we compared the effect of compound madecassol on wound healing at 3rd, 7th, 14th, and 21th postoperative days. This study examined the histologic findings and the gross findings which were wound size, epithelization and quality of granulation tissue. In this study, compound madecassol showed lower degree of inflammatory infiltration, shorter inflammatory phases and less wound contraction. The number of the myofibroblast in the group of compound madecassol were fewer than other groups. Granulation tissue of the compound madecassol was relatively healthier than others. There were no significant difference of re-epithelization between compound madecassol and other groups. In conclusion, compound madecassol can reduce excessive wound contraction and promotes wound healing process.

BACKGROUND: Even though excellent impression materials are now available for making accurate replication for hard and soft tissue, the numerous dentists have faced lots of obstacles in making simultaneous impressions of multiple abutments. CASE DESCRIPTION: This article describes a modified method of tray fabrication using auto-polymerizing acrylic resin and impression technique for multiple prepared teeth in cases with limitations and difficulties in taking dental impressions. CLINICAL IMPLICATION: This segmental tray technique has several advantages, including higher impression quality, fewer impressions, and being more comfortable for the patient and less stressful for the clinician.
