BACKGROUND Diabetes mellitus (DM) is a cluster of metabolic diseases with chronic hyperglycemia as a defining feature, associated with long-term organ damage and dysfunction. In this study we examined the effect of Tulbaghia violacea rhizome methanolic extract on blood glucose and lipids in normal and streptozotocin-induced diabetic rats. MATERIALS AND METHODS Male Wistar rats (250-300g) were...

OBJECTIVES To investigate the otoprotective effects of mouse nerve growth factor (mNGF) in A/J mice. METHODS The mice at postnatal day 7 (P7) were randomly separated into a mNGF treated group (mNGF group) and a distilled water (for injection) treated group (control group). The mNGF dissolved in distilled water or distilled water alone was given to the mice once every other day from P7 by intr...

CONTEXT Calcium hydroxide (Ca(OH)2) paste filling is largely used as intra-canal medication and can be combined with different vehicles. Removal of that paste should be preceded by obturation, to avoid the occurrence of apical microleakage. AIMS To evaluate the efficiency of removal of pulp Ca(OH)2, from using different vehicles (water, propylene glycol) and removal techniques (mechanical and...

The influence of dipping in hot salt solution on water absorption in nylon6 composites with dispersed aluminum powders was investigated. Dipping in hot salt solution (3mass%NaCl in distilled water) for 10 s at 373K increased the overweight of composite samples, whereas the addition of aluminum with dispersed powders (A1-addition) from zero to 40 vol%Al decreased the overweigh of the sample. Bas...

on intravenous quinine injections. As this place is a hotbed of malaria, I deal with several hundred malaria cases each year, and for the past few months I have been in the habit of giving quinine intravenously, having abandoned the intramuscular route as, in some cases, it resulted in abscesses. Since reading Dr. Vasavada's letter I have given more than a hundred intravenous quinine injections...

The Solution.?The required dose should be dissolved in sterile distilled water in order to make a 5 per cent, solution, i.e., 0.05 gramme will require 1 c.c., 0.1 gramme 2 c.c., 0.2 gramme 4 c.c., and 0.3 gramme 6 c.c. The solution should not be boiled and should be prepared freshly. (We have used solutions that have been kept 48 and even 72 hours without any ill-effects but as there is danger ...

In Nitella the action curve has two peaks, apparently because both protoplasmic surfaces (inner and outer) are sensitive to K(+). Leaching in distilled water makes the outer surface insensitive to K(+). We may therefore expect the action curve to have only one peak. This expectation is realized. The action curve thus obtained resembles that of Chara which has an outer protoplasmic surface that ...

Not only does distilled water take away the irritability of Nitella but it also changes its behavior toward potassium. In normal cells potassium is strongly negative to sodium but after sufficient exposure to distilled water this effect disappears. It can be restored by returning the cells to their normal environment or to a suitable nutrient solution. This change in the protoplasm seems to be ...

The aim of this study was to evaluate the solubility of gutta-percha in four organic solvents used in endodontics. The solubility of gutta-percha (Dentsply) was assessed in xylol, orange oil, eucalyptol, chloroform and distilled water. A hundred and fifty samples of gutta-percha were prepared using a standardized stainless steel mould and divided into five groups for immersion in the different ...
