RESUMO
We present here an interesting case of anorexia nervosa that was well controlled by Ancyu-san, a traditional Japanese herbal medicine. A 17-year-old student was re-admitted to our department in December of 1990, because of anorexia and eating disorders. She had lost approximately 12kg body weight during 3 months. She was 154cm tall and weighed 26kg. Her blood pressure was 75/40mmHg, her pulse rate was 30beats/min, and her body temparature was 34.4°C. She was extremely emaciated and hyperactive. On oriental examination, a shallow complexion, a cold feeling in the limbs, postprandial headaches, and a feeling of obstruction of the external ear. Her pulse was slow and feeble. Abdominal examination revealed that the abdominal strength was reduced to 2/5 with Inai-teisui (abdominal water and gas retention). Based on these findings, this case was diagnosed as Deficient Spleen and Stomach due to Deficient Ki and Blood combined with Stagnated Ki, and therefore a candidate for the Kampo formula Ancyu-san. The patient began medication in January 1991. Her appetite improved gradually and her body weight increased from 26kg to 47kg in two months.
RESUMO
Silicate compounds are added as extenders to dusts, flow dusts (FDs) and wettable powders, meaning that it can be predicted to contain free silica, which in turn affects the incidence of pneumoconiosis. The percentage of free silica content was measured by X-ray diffraction in 18 pesticides consisting of 3 types of dusts, 4 types of FDs and 11 types of wettable powders. As a results, free silica was identified in 14 of pesticides as follows: 22-34% in dusts, 3-11% in FDs and less than 1% to 20% in wettable powders. The percentages contained in the FDs were lower than in the dusts, probably because crystal structures became amorphous during the processing of FDs into super fine gradules with a mean particule size of 2μm.<BR>The levels of dust exposure during spraying were measured with respect to Sumithion dust, Morestan FD and TPN FD by classifying them into respirable dust of less than 7.07μm in aerodynamic diameter (which is liable to be deposited in the lung) and total dust. When the concentration of a dust to which sprayers were exposed was compared with the TLV established taking into free silica content based on recommendation of the Japan Association of Industrial Health, the dust spray levels were 75-fold in the case of respirable dust and 53-fold for total dust, those for the spraying of FDs were 7-fold for respirable dust and 3-fold for total dust.<BR>These results suggest the necessity of using pesticides with low free silica content. It is also considered necessary for sprayers to wear dust respirators.
