The most common disease in Korea is smoking and the number of the sufferers is about twelve million. The prevalence of smoking among doctors may indicate the likelihood of success of population-based anti-tobacco campaigns. It has been established that the decline in the prevalence of smoking among physicians has preceded the decline in the general population according to the Kunz's two-phase model in smoking epidemic. There is also evidence that physicians who smoke are less likely to counsel patients about the hazards of smoking. For these three reasons it is important to understand the current smoking status among medical doctors. The smoking rate was reported to be 34.9% among Korean doctors in male and 2.3% in female in 2000. In the same period it has been reported to be 67.6% in male and 3% in female in the general population. According to Kunz, Korea is a mature country in terms of smoking epidemic. All the doctors should be well aware that there are effective and scientific ways of smoking cessation. But the proportion of doctors who have never been educated for smoking cessation was 97.9%. Undergraduate and continuous medical education for smoking cessation should be reinforced. The drop smoking rate among Korean medical doctors is mandatory.

The metacercariae of Metagonimus yokogawai were isolated from the sweetfish Plecoglossus altivelis, clollected at Hwagae, South Kyongsang Do, one of the newly known endemic foci of metagonimiasis in Korea. The body structure of metacercaria of M.yokogawai was described and the measurements of the excysted metacercaria were also made. In order to know the distribution of metacercariae within the host, the rate of infection and the intensity of infection, a total of 10 sweet fishes was examined and it was found all infected, from which a total of 38,511 metacercariae was isolated. The number of metacercariae in a fish varied from 219 to 14,427. The average number of metacercaria per fish was 3,851. The distribution of metacercariae in the four divided parts of fish was observed in the following order; number of metacercaria in the muscles; 2,417 (62.8%), in the subcutaneous tissues; 1,126.9 (29.3%), and on the scale; 291.9(7.7%). The development of the metacercaria of M. yokogawai in the mouse host was experimentally traced every day for 10 days after infection . In an earlier period of infection, the growth rate of the genital primordia was distinctly high, particularly in the testes. The seminal receptable and seminal vesicle became clearly recognized in measurable size at 4 days after infection. The vitelline follicles and their ducts were also first visible in the living specimens at 6 days after infection. The oral sucker was larger in size than the ventral sucker in an early stage of the worms, however after 7 days after infection it reversed. The posterior part of body began to extend since two days after infection. Fully matured worms were able to collect only after 7 days after infection. At this stage, the body of worm became 0.7 mm long and 0.3 mm wide. The first positive appearance of eggs in the uterine tubule and in feces was on the 6th day and 10th day of infection, respectively. In an earlier stage of infection, the worms were found mostly in the upper portion of small intestine and the recovery rates of the worms were high, however according to the course of infection in later stage they were seen rather in the lower part of the intestine and the recovery rate also decreased.
