A 41-year-old woman liked farm chemical-free (pesticid-free) vegetables. She was admitted for severe upper abdominal pain. Biliary ascariasis was suspected upon abdominal ultrasonographic examination. ERC (Endoscopic Retrograde Cholangiography) was performed and a linear filling defect was shown in the bile duct. We diagnosed her case as biliary ascariasis. And then, we removed a worm from the bile duct using stone extracer basket forceps. After this, she was given pyrantel pamoate.Abdominal ultrasonographic examination was helpful in diagnostic screening for biliary ascariasis. ERC and basket forceps were useful in removing the parasite.

We tried to evaluate the right ventricular function using a modified Swan-Ganz catheter with a rapid responsive thermistor. Twenty-four dogs comprised this series. Twelve were the model of left heart failure (Group A), and the other twelve were the model of right heart failure (Group B) produced by multiple ligation of coronary arteries. Dogs were studied for some of the circulatory indices before and after ligation with left atrial pressure at 10, 15 and 20mmHg in group A, and right atrial pressure at 10, 15 and 20mmHg in group B by volume loading. In group A, when the left atrial pressure was kept constant, right ventricular ejection fraction (RVEF) and right ventricular stroke work index (RVSWI) were decreased significantly after the ligation of coronary arteries. But there was no significant change in the peak right ventricular pressure-right ventricular endsystolic volume index ratio (peak RVP/RVESVI) associated with ligation. In group B, significant changes were observed in RVEF, RVSWI and peak RVP/RVESVI. Thus, it was found that right ventricular contractility in selective left heart failure was not reduced. E_max was considered to be a valuable index of ventricular contractility not affected by preload and afterload of ventricle, but this index is not easily measured clinically. The index peak RVP/RVESVI which is nearly equivalent to E_max, has an advantage in that it can be determined by the thermodilution method widely used in general. We conclude that this index is very useful to us for post-operative care in cardiac surgery.

Nowadays the agricultural production system in the farm area has remarkably been changed and this has influenced the farmers in many aspects of life.
We tried by epidemiologic cross-sectional survey to ascertain the health level of 6, 597 farmers, who are self-supporting and middle class in the sixty-seven different districts of Kumamoto Prefecture. It is noticeable that judging from the difference of districts, the health level of the farmers who have a big gricultural production is low, and judging from the difference of the class, that of the farmers who have other jobs besides agriculture is low, too In general, the health level of males is relatively higher than that of females, but the health level of males is higher than that of females, depending on the class difference.
Generally speaking, we noticed that the health level of female is very low, and at the same time the variation of the health level of females is more remarkable than that of males, depending on the quality of the district in which they live.
These resutls of these investigations should be utilized as the basic materials source for a prospective survey of changing farm village from now.
