Watary extract of ALLIUM SATIVUM when administered Intravenously (I.V.) to NORMOTENSIVE dogs, produced a significant fall in their mean blood pressure. This effect was not antagonized by atropine or antihistamines. The extract increased the activity of Isolated Guinea Pig Ileum preparation. This effect of A Sativum was blocked by Diamentane (JPMA 31:12, 1981).

We show that freeze-dried actin filaments which have been rotary shadowed with a light coat of platinum appear very similar in morphology and width to negatively-stained filaments. The addition of a thicker coat of platinum to such preparations gives the actin filaments a different morphology and width, which are similar to those of the rotary-shadowed, quick-frozen filaments described by Heuse...

The effect of oven drying at 50ᵒC ± 1ᵒC for 9 hour, 70ᵒC ± 1ᵒC for 5 hour and freeze drying on retention of chlorophyll, riboflavin, niacin, ascorbic acid and carotenoids in herbal preparation consisting of 8 medicinal plants was evaluated. The medicinal plants selected were leaves of Apium graveolens (saderi), Averrhoa bilimbi (belimbing buluh), Centella asiatica (pegaga), Mentha arvensis (pud...

U ltrastructure of the epicuticular wax of four commercially grown Canadian cultivars of canola (Brassica campestris cvs. Tobin and Candle, B. napus cvs. Altex and W estar) was investigated. Freeze-drying and air-drying methods of specimen preparation for scanning electron microscopy were compared. The freeze-drying method resulted in disruption and possible washing away of wax crystals, wherea...

The aim of this research effort was to investigate the role of various sugar substrates in the growth medium upon thermotolerance and upon survival during storage after freeze-drying of Lactobacillus bulgaricus. Addition of the sugars tested to the growth medium, and of these and sorbitol to the drying medium (skim milk) was investigated so as to determine whether a relationship exists between ...

Sperm preservation is a useful technique for the maintenance of biological resources in experimental and domestic animals, and in wild animals. A new preservation method has been developed that enables sperm to be stored for a long time in a refrigerator at 4 °C. Sperm are freeze-dried in a solution containing 10 mM Tris and 1 mM EDTA. Using this method, liquid nitrogen is not required for the ...

Secondary phenolic metabolites play an important role in plant defense mechanisms, and increasing evidence indicates that many are important in human health. To date, few studies have investigated the impact of various agricultural practices on levels of secondary plant metabolites. To address this issue, the total phenolic (TP) content of marionberries, strawberries, and corn grown by sustaina...

the freeze-drying process. Continued viability of rehydrated cells during incubation at 37 C for 3 hours was dependent on the composition of the suspending medium. The number of viable organisms decreased greatly when suspended and incubated in water. Several salts were effective in maintaining higher viable cell counts. Maximum recovery of viable cells of one dried preparation rehydrated in ma...
