A method for routine preparation of a solution of 133 Xe gas in saline from commercially available m Xe gas ampoules is described and evaluated. At room temperature and atmospheric pressure, about 25% of the mxe gas dissolves in saline. Xenon-133 binds to the syringe wall or may escape into the air when stored in sealed plastic syringes. Preparation immediately prior to use, short-term storage ...

PURPOSE To evaluate the efficacy of pure honey and 20% autologous serum and BSS in corneal epithelial healing in rabbits after 48 hours. METHODS All solutions were applied after an epithelial removal of 13-millimeters diameter area. Areas of epithelial healing were studied at 12, 24 and 48 hours. The eyes were treated every four hours during 2 days. All treated eyes were assigned to a control...

was also given. But the milk could not be taken. Several different cows were tried in turn without any benefit. I then thought of immunising the baby against cow's milk, which I injected hypodermically and unboiled, diluted with normal saline solution, under full aseptic precautions. The doses given were as follows :? 25-2-'24. 0.01 c.c., no reaction. 28-2-'24. 0.02 c c., no reaction. 2-3-'24. ...

Publications reporting results of small-molecule screens are becoming more common as academic researchers increasingly make use of high-throughput screening (HTS) facilities. However, no standards have been formally established for reporting small-molecule screening data, and often key information important for the evaluation and interpretation of results is omitted in published HTS protocols. ...

PURPOSE To assess the viability of McFarlane skin flaps in rats with administration of sildenafil. METHODS Twenty Wistar rats were distributed into two groups: Control (dorsal skin flap, subdermal application of saline solution at 0.9%) and Study (dorsal skin flap, subdermal application of sildenafil). Seven days after the surgery, flaps were photographed and graphically rendered. Then, they ...

pH) most ofthis lipid again became extractable only with difficulty. 5. The parallelism between the two criteria of decomposition used, namely dispersibility in sodium chloride solution-ether and extractability of the lipid with ether, was not complete. The authors areindebtedto DrK. McQuillen for assistance with the mobility measurements. The work described in this paper has been carried out a...
