...extracted in minute quantities by highly complex processes from vats in which countless billions of colon bacteria, Escherichia coli, have been grown...
Nearly as many gas patients, about 20% of the total, produce either too much or too little gastric acid. Shortage of acid favors establishment of abnormal bacteria that ferment food in the intestines; this condition usually can be corrected by medicine containing dilute hydrochloric acid. Hyperacidity and peptic ulcer may lead to an excess production of carbon dioxide, and hence to flatulence, through the interaction of gastric acid on bicarbonates from the digestive juices. Standard ulcer medicines -antacids in liquid or tablet form-and diet should relieve this type of gaseousness...
Surveyor's dramatic recovery overshadowed another space venture involving 1,000 vinegar gnats, 1,000 flour beetles, 560 wasps, 120 frog eggs, 875 amoebae, 13,000 bacteria cells, 78 wheat seedlings, nine pepper plants, 10 million spores of orange bread mold and 64 blue spiderwort. All this was packed aboard a space ark called Biosatellite 2 and launched into earth orbit from Cape Kennedy...
...Johnson opened the pepper plant packages and found their leaves folded down and turned under. "This is astounding," he said. "It shows that gravity really controls the orientation of a plant to a much greater extent than I had anticipated." And to Biologist Rudolph Mattoni, in charge of the bacteria experiment, there were "very, very preliminary indications that the stuff in space grew better and to a greater density than the same stuff on earth...
...wane. In the universities and in the National Institute of Dental Research, most of the focus is on periodontal disease, which actually claims three times as many teeth as do cavities when people are past 35. To date, the main preventive treatment has been regular cleaning to remove the bacteria-containing film and tartar. Within two years, several commercial firms may be marketing new anti-periodontal-disease products in the form of toothpastes and mouthwashes...
