Concerning the intoxication by agricultural chemicals, adsorption removal of paraquat by activated carbons for initial treatment of paraquat intoxication in vitro was investigated. The amount of paraquat adsorbed was significantly related to the surface pH of activated carbon. It was not found the significant correlation between amount of paraquat adsorbed and physical properties of ten kinds of activated carbons.
Moreover, the influence of sorbitol addition on the amount of paraquat adsorbed was studid. The amonut of paraquat adsorbed onto activated carbon was unaffected by sorbitol addition.

For the security of water quality in rural areas, adsorption removal of phenol which is one of disinfectants for excretions by six kinds of commercial activated carbon was investigated.
At equilibrium concentration of 1 and 10 ppm, activated carbon indicated pH 10.19 adsorbed phenol as much as 2.17 and 1.84 times compared with activated carbon indicated pH 3.06, respectively. At low equilibrium concentration of phenol, the amount adsorbed was significantly influenced by surface pH of activated carbon (p <0.05).
These results suggest that the difference in amount of phenol adsorbed onto activated carbon is due to the interaction between phenol and surface oxygen groups on the adsorbent. Therefore, it is concluded that the activated carbon of which surface is basic suitable for the adsorption removal of phenol in the agricultural waste waters.

For the preservation of health in rural areas, this paper reports on the variation of human serum lipids by intaking lentinus edodes.
Serum lipids levels showed no significant change by intaking lentinus edodes that amounts of 20, 40 and 60g per day each for 5 days. From data of correlationship between serum lipid levels and nutrition intake of experimental diet, it was recognized that high-density-lipoprotein cholesterol level was directly proportional to carbohydrate-fat ratio significantly (p< 0.02), and was inversely proportional to fat intake, fat-protein ratio and carbohydrate-protein ratio significantly (p< 0.05), respectively. Triglycerides level was inversely proportional to protein intake significantly (p< 0.05).
These results concluded that the decrease of serum cholesterol level by intaking of lentinus edodes in healthy young men whose serum cholesterol levels were in normal range was not recognized.

Concerning the agricultural waste water treatment, adsorption removal of cresol which is one of disinfectants by commercial activated carbon was investigated.
It was not found the significant correlation between amount of cresol adsorbed and physical properties of eight kinds of activated carbon. The intraparticle diffusivity of cresol onto the pores of activated carbon was significantly related to the mesopore volume.
In the treatment of agricultural waste water, it is concluded that the activated carbon which is rich in mesopore volume is suitable for the adsorption removal of cresol from the standpoint of adsorption rate.

Oral adsorbents used in the primary treatment of paraquat intoxication were studied in saline to evaluate their effectiveness in terms of removal ratio and removal rate.
Forty kinds of materials were tested as paraquat adsorbents.
Although cation exchange resin had the greatest removal ratio for paraquat, a high removal ratio was registered by an activated carbon derived from petroleum pitch. A significant correlation between removal ratio and the degree of crosslinkage in the resin was found.
The degree of paraquat concentration decrease was high when cation exchange resin was used. A significant correlation was found between the kinetic constant, which was calculated from the equation for a first-order reaction, and the degree of crosslinkage in the resin.

The effects of large doses of vitamin C on serum alkaline phosphatase activity were examined in six young healthy volunteers. The experiment lasted 30 days. The results obtained were as follows.:
he mean basal AL-P level in the six subjects was 5.9±2.3 K-A unit. Upon administration of 1g/day of vitamin C, the values increased to the mean of 6.9±2.6 K-A unit, while after a dose of 10g/day, the mean came to 6.8±2.1 K-A unit. All the subjects showed increased AL-P serum levels relative to the control period.

In search of a better primary treatment of acute boric acid poisoning, the adsorption capacity of boric acid onto activated carbon as an antidote was investigated in vitro.
Wide differences in the amount of boric acid adsorbed were recognized depending on individual activated carbons. In order to elucidate the dominant factor in boric acid adsorption, correlations between the properties of activated carbon and the amounts of boric acid adsorbed are discussed. A significant correlation was recognized between the surface pH of activated carbon and the amount of boric acid adsorbed in low equilibrium concentration. It is assumed that the surface pH of activated carbon is a chief factor affecting the amount of boric acid adsorbed.

Relationship between SGOT/SGPT ratio and energy intake were investigated in 1030 subjects (373 males, 657 females). These figures were taken from epidemiological survey of the Tokushima prefecture from 1975 to 1980.
The results of the survey were as follows.
1) Energy intakes in reversal group (SGOT/SGPT <1) was higher than that in nromal group (SGOT/SGPT >1).
2) Body weight in reversal group was higher than that in normal group except young woman (18-39 years).
3) Incidence of reversal of SGOT/SGPT ratio showed increasing values as energy intakes levels increased.
It is possible to conclude from the results that SGOT/SGPT ratio was affected by energy intakes.

The effects of the food intake pattern on the activity and fraction pattern of serum γ-glutamyl transpeptidase (γ-GTP) were examined in 257 healthy Japanese men.
Applying the technique of factor analysis to the food intake data, the following three factors were extracted. The first factor (F1): meats, eggs, and vegetables had a highly positive factor loading. The second factor (F2): wheat had a highly positive factor loading, while rice had a highly negative factor loading. This factor was considered to be a “wheat versus rice factor”. The third factor (F3) could not be explained simply in terms of its factor. The scores of the first two factors for the 257 subjects were calculated.
Significantly negative correlations were observed between the percentage of GT₁ fraction and the factor score of F1 (r=-0.230, p<0.01), between the percentage of GT₁ fraction and the factor score of F2 (r=-0.187, p<0.01). The total serum γ-GTP activity was not correlated with the factor score. These results suggested that the percentage of GT₁ fraction is influenced by the pattern of food intake.

The relationship between serum creatine phosphokinase (CPK) activity and labor strength was examined.
Our epidemiological study showed thar the serum CPK activity in a group of men who worked over ten hours was significantly higher than that in the other groups who worked less than ten hours. In women, the serum CPK activity in a group who worked over seven hours was significantly higher than that in the other groups. The serum CPK activity in fishermen was significantly higher than that in those engaged in other than fishery.
In a laboratory study, test subjects were divided into 3 groups to perform 3 types (30%, 50%, 70% of VO_2max) of exercise for 6 weeks. A rise in the serum CPK activity was noted in every group during exercise. The mean increase for these groups were 44.0 %, 48.1 % and 67.9 %, respectively.
