The objective of this work is identifying changes in the collagen bands in heated and rehydrated dentine. We use bovine dentine slices that were heated in oven between 100 and 300 degrees C. The sample hydration was conducted in sodium chloride solution at 0.9 wt.%; the spectra were acquired by a Fourier transform infrared spectrometer in the spectral range of 4000-400 cm-1. Our results show a ...

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 ...

Commercial 0.9% saline solution for infusion has a pH around 5.5. There are many reasons for this acidity, some of them still obscure. It is also true that infusion of normal saline can lead to metabolic acidaemia, yet the link between the acidity of saline solution and the acidaemia it can engender is not straightforward. This commentary draws together the known and putative sources of acidity...

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. ...
