Abstract
The physical and laboratory examinations were performed to 74 cases who have cultured vegetables and flowers in a hothause for at least ten years. As the control cases, the same examination were performed to 54 cases of the farmar who have never worked in a hothouse. The subjects of both groups have been used the agricultured medicines such as organic phosphide, organic chloride and dietlylen sodium bis-ditio carbamate. The examination included blood pressure, urinalysis, ECG, 50 g OGTT, CBC and Liver function test. The results of these examinations were not significantly differed except for the value of cholin esterase. The mean serum level of cholin esterase was significantly lower in hothause group compared with that in field group, although the levels were within normal levels in both groups. This result suggests that some improvement of a circumstances in hothause may be necessary.
