Notizen: A “vegetable leather,” possessing a supple, leathery texture, was prepared with sweet potato (SP) and other ingredients. Samples were analyzed at 0, 30, and 60 days storage. Texture, but not flavor or acceptance, was affected by experimental factors. Ingredients had only minor effects on composition. Mean values were: moisture, 5.9%; crude protein, 5.8%; crude fat, 4.9%; ash, 2.7%; crude fiber, 2.2%; and nitrogen-free extract, 84.8%. Dietary fiber was 4.1%. Color of the leather was orange; pH was 4.8; annd caloric content was 17.3 kJ per g. Water activity ranged from 0.48 for leather with SP and apple to 0.58 for leather with SP and without apple. Microbiological counts of samples were low.

Notizen: Sweet sorghum syrup was heated at 49° to 71°C and filled into glass jars of 200 mL capacity that contained each of four microorganisms (Bacillus subtilis; Byssochlamys nivea; Saccharomyces rouxii; and Aspergillus niger) at 0, 1,000 or 10,000 CFU/mL syrup. Counts were determined on syrup immediately after filling into the jars and after four months storage. The heated syrup at all temperatures significantly reduced the survival of bacteria and fungi at the time of filling. After four months, no bacteria could be detected in syrup at each temperature, and no fungi could be detected at 66° and 71°C. The heat of syrup at 71°C or lower did not cause single layer polypropylene jars to become deformed; however, at 77° and 82°C deformation occurred such that the jars were unsatisfactory for the packaging of syrup. Therefore, syrup can be filled at 66° and 71° into single layer polypropylene jars. At these temperatures, common spoilage microflora were destroyed or inactivated during storage, and the plastic jars did not become deformed.

Notizen: Abstract The indole alkaloid ibogaine (NIH 10567, Endabuse) is currently being examined for its potential utility in the treatment of cocaine and opioid addiction. However, a clearly defined molecular mechanism of action for ibogaine's putative anti-addictive properties has not been delineated. Radioligand binding assays targeting over 50 distinct neurotransmitter receptors, ion channels, and select second messenger systems were employed to establish a broad in vitro pharmacological profile for ibogaine. These studies revealed that ibogaine interacted with a wide variety of receptors at concentrations of 1–100 µM. These included the mu, delta, kappa, opiate, 5HT2, 5HT3, and muscarinic1 and 2 receptors, and the dopamine, norepinephrine, and serotonin uptake sites. In addition, ibogaine interacted withN-methyl-d-aspartic acid (NMDA) associated ion and sodium ion channels as determined by the inhibition of [3H]MK-801 and [3H]bactrachotoxin A 20-α-benzoate binding (BTX-B), respectively. This broad spectrum of activity may in part be responsible for ibogaine's putative anti-addictive activity.
