It is necessary for us to be accustomed to low-salt diets in order to prevent adult diseases. Contents of salt, sodium and potassium in commercial low-salt foodstuffs and low-salt diets using them were measured. As to low-salt soy goods, the salt contents in salt-weak (usujio), salt-reduced (gen-en)and salt-free (mu-en) soy goods were 88, 56 and 20% of those in common soy goods, respectively. As to low-salt miso goods, however, there was no correlation between commercial name and salt content. No significant differences were observed between the measured and indicated values on the contents of salt, sodium and potassium in low-salt foodstuffs. The content of salt in low-salt diets was reduced to about 32-68% of that in ordinary diets.

The development and health of infant children are deeply influenced by their eating habits. Its foundation is mainly formed during the wearing period (about one and half years old). Therefore in the wearing period the role of mothers is very important for their children's eating. By the medical examination of one-and-half-year-old infants in Osaka City, we can get the following important facts:
In the wearing period, the appropriate volume of cow's milk is 180-400ml, though mothers are generally apt to depend on milk only.
Not only nutritious contents but child care with zealous mothering brings good effects to the formation of eating habits and keeps infants from illness and decayed teeth.

Bacterial isolation from the standard activated sludge was performed, their physiological characteristics such as salt and drug resistance were examined, and bacterial flora of the satndard activated sludge was determined. A lot of strains were isolatedfromthestandardactivated sludge under loth saline and fresh water conditions, when a sample was incubated for 3 days at 30°C with polypeptone-meat extract agar plate. It was found that total viable cells were 2.6×10⁷ cells/ml under fresh water condition and 9.7×10⁵ cells/ml under saline condition. The strains from typical colonies were idendified taxonomically, they were Acinetobacter sp., Bacillus sp., Corynebacterium sp., Enterobaceriaceae, Flavobacterium sp. and Moraxella sp. Dominant strains were Acinetobacter sp., Corynebacterium sp. and Enterobacteriaceae and they occupied 37, 25 and 15%, respectively, under fresh water condition. Under saline condition Bacillus sp. was dominant and 78%. PY medium was the best one compared with other media such as PPYE, SS and CF for culture medium.
Corynebacterium sp. was able to grow in 2.5M NaCl hypertonic environment, while Bacillus sp. (S2) isolated under salinecondition grew in 3.5M NaCl concentration. The salt resistance in both strains was not specific for Na⁺, optimal concentration for growth of both strains was 0.5M NaCl, optimal pH range was 7-8, temperature, 30-35°C. All of isolated strains had drug resistance to some antibiotics and salt resistant strains showed also stronger drug resistance in saline environment.

After the occurrence of Vibrio cholerae serotype Olin the Shorenji estuary on September 25, 1982, an etiological survey for cholera strain was carried out along the river from September to December 1982. Out of 11 water samples obtained from the Shorenji River, 7 specimens were demonstrated to be contaminated with V. cholerae biovar eltor Inaba. Positive sources supposed to be responsible to the river contamination were examined. However, no isolates was found either from the effluent of Konohana Sewage Disposal Plant or industrial drainages that discharged into the river. Fishes caught in the river or feces of workers engaged in the Flood Control at the river were also negative regarding cholera infection. Therefore, a question where this V. cholerae came from remained unsolved. Amounts of cholera toxin produced by the isolates were from 16 to 256 in reciprocal titer by the reverse passive latex agglutination (RPLA) test. Epidemiological survey on V. cholerae serotype non-01 (NAG) was carried out on various rivers in Osaka City from September 1981 to August 1982. Positive isolation rate of NAG was 61.9% from river water and 26.1% from mud of river. The positive isolation rate of NAG from water was at its peak in summer season (July to September). Regarding specified basin of river, the highest level of NAG comtamination was observed in the basin along the Neyagawa and Kyu-Yodogawa River. As for the mud of river, the basin along the Hirano River was more contaminated by NAG than other basin. In the bacterial population by MPN (most probable number), the largest value, 1400/100ml, was found in the water sample from the Neyagawa River. Positive producers of cholera toxin (above 2 in reciprocal titer by RPLA) were 88.7% among 186 NAG strains.
