Objective: We analyzed the number of deaths due to poisoning by pesticides over 38 years through vital statistics published annually by the Ministry of Health, Labour and Welfare of the Japanese government, from 1968 through 2005. Materials and Methods: Data not published as vital statistics were obtained from the Ministry of Health, Labour and Welfare Statistics and Information Department. The vital statistics provide the numbers of deaths with individual causes of death classified by sex and 5-year age group. We also calculated age-adjusted death rates by this classification, using a direct method based on the 1985 Japanese model population. Results: Deaths from pesticide poisoning increased rapidly beginning in 1982, reached a peak in 1986 (death rate per 100,000 population: 2.6 in males and 1.7 in females) and declined gradually thereafter. In the most recent several years, these figures have declined to levels previously unseen (death rate per 100,000 population: 0.4 in males and 0.3 in females). A difference in death rates between the sexes was observed at every age level, with death rates of males approximately 1.1-1.5-fold those of females. In the 1985-1987 data, these figures were highest in the three prefectures of northern Kanto (Tochigi, Gunma, and Ibaraki Prefectures; crude death rates per 100,000 population: 6.8, 6.8, 6.2, respectively), followed by that in Kagoshima Prefecture (5.0). In the 2003-2005 data, the figure was highest in southern Kyushu (Miyazaki Prefecture; crude death rate per 100,000 population: 1.9), followed by Tochigi (1.6), Ibaraki (1.4), and Kagoshima (1.4). Conclusions: Deaths from pesticide poisoning were extremely well correlated to the history of paraquat. Through the 1985 Advisory Resolution on Paraquat Regulations by the Japanese Association of Rural Medicine and other public health-oriented efforts, the concentration of highly fatal paraquat formulations was reduced, leading to discontinuation of its production, customer identification was strictly enforced when purchasing pesticides, and people's safety consciousness regarding pesticides improved. We regard and these developments as having had the greatest contribution to the reduction in deaths from pesticide poisoning.

We report three cases with somatoform disorder which were considered as “Hontonki” disease, successfully treated with keishikakeito. Case1 was a 34-year old male who was suffering from headache and palpitation. He said ‘Something pierces and it goes up from the chest to the head.' We considered his complaint as Hontonki disease and administered keishikakeito. After one week, the headache disappeared and four weeks later, palpitation and tinnitus were definitely improved. Case2 was a 22-year old male. His complaints were excessive strain and general fatigue. Because he had coldness of lower extremities and spasmodic headache, we interpreted these symptoms Hontonki disease and administered keishikakeito. After that these symptoms and his psychological test scores improved markedly. Case 3 was a 75-year old female. Severe headache and palpitations presented after remodeling her home. Three weeks later taking keishikakeito, her symptoms had disappeared dramatically. Recently, Hontonki disease are often compared with panic disorder, and it is possible that some somatoform disorder cases include Hontonki disease. It is important to consider the possibility of Hontonki disease behind the physical complaints such as headache and palpitation, when we use keishikakeito.

We report a case of serous gonarthritis with nonproductive cough successfully treated with Eppikajutsuto. A 37-year-old Japanese man developed a right genicular arthrocele with nonproductive cough, in October X. Over 100 ml of serous synovial fluid was drained via an arthrocentesis puncture procedure. Although he was treated with nonsteroidal anti-inflammatory agents by an orthopedist, under a diagnosis of serous gonarthritis, his symptoms did not improve. Laboratory findings suggested inflammatory conditions (serum CRP 3.4 mg/dl, ESR 76 mm/h). At the time of his first visit in January X+1, orthopedic examinations revealed that rheumatoid arthritis was unlikely, based on negative physical and laboratory findings. A contrast MRI knee joint scan did not demonstrate any tumor-like mass of synovium which would indicate pigmented villonodular synovitis. And orthopedists found it difficult to specify the cause of his serous gonarthritis. After a common cold in December X, cough stimulated by cold exposure was superimposed on serous gonarthritis.We utilized Eppikajutsuto under the interpretation that both his genicular arthrocele and nonproductive cough were due to a “sui” disturbance. This Eppikajutsuto therapy reduced his genicular arthrocele and nonproductive cough in1month. His symptoms and inflammatory reactions were completely improved in 3 months, regardless of gradual withdrawal of his medication.

We report a case with an intractable jugular sense of discomfort, with dryness and nonproductive cough successfully treated with soshikokito. A 62-year-old Japanese man developed jugular sense of discomfort with dryness and nonproductive cough, after odontotherapy in October. Although he was treated with Western drugs by an otolaryngologist, under the diagnosis of xerostomia with no mechanical problems, his symptoms did not disappear. The symptoms followed a protracted course, and he further developed a loss of appetite. At the time of first visit in October, otorhinolaryngological studies showed no structural lesions or problems, with the exception of minimum salivation in the normal range on a gum test. There was no evidence of dry eyes. With the diagnosis of xerostomia, Bakumondoto-go-hangekobokuto was administered for a month but showed no sign of improvement. Making a shift to bukuryoin-go-hangekobokuto regained his appetite, but did not produce any improvement on dryness. We then utilized soshikokito under the interpretation that both dryness and nonproductive cough is ki-gyaku. The soshikokito therapy reduced his dryness in a month's time. Additionally, his nonproductive cough gradually decreased, and within 11 months after, he had no symptoms, regardless of a gradual medication withdrawal.

The environmental contaminant benzo[a]pyrene (B[a]P) has been regarded as one of the pathogens of oral premalignant and malignant lesions. To elucidate the pathogenesis of oral premalignancies, B[a]P-induced dysplasia of the murine tongue was investigated for G1-associated cell cycle regulation. B[a]P solution was applied orally up to six weeks to induce epithelial dysplasia of the tongue. BrdU incorporation and the expression of p21, cyclin D1, and CDK4 were examined by immunohistochemistry and Western blotting. Rb phosphorylation and E2F-Rb binding were examined by immunoprecipitation and Western blotting. B[a]P treatment resulted in dysplastic changes and active DNA synthesis in the tongue epithelia. Immunohistochemical analyses showed p21 up-regulation and cyclin D1/CDK4 overexpression in B[a]P-induced dysplasia. Rb hyperphosphorylation and E2F release were caused by B[a]P treatment. Thus, dysregulation of G1-phase regulation is likely to be an important event in the development of oral epithelial dysplasia in mice.

Six (1.2%) of 501 patients sustained phrenic nerve injury during operation for congenital heart disease at our institutions between 1992 and 1998. The diagnosis was confirmed by percutaneous stimulation of the phrenic nerve. All but 1 patient were less than 9 months old, and the average weight was 3.6kg. All 6 patients underwent diaphragmatic plication and were extubated by 7 days after operation. Percutaneous stimulation of the phrenic nerve allowed direct assessment of phrenic nerve function which was difficult to detect by clinical and radiological evidence. This method can be non-invasively used at the bedside to facilitate early and accurate diagnosis of phrenic nerve palsy.

1) We compiled lists of accredited training hospitals for postgraduate education from the matching program list and of hospitals that employ board-certified specialists in emergency medicine.We then evaluated the number of training hospitals that employ board-certified specialists.
2) There are 1072 accredited hospitals for postgraduate education. However, only 546 (50.8%) of these hospitals employ board-certified specialists in emergency medicine.
3) Accredited training hospitals with emergency-medicine specialists are prevalent in Okinawa, Tokushima, and Kagawa prefectures.However, the prevalence of these hospitals is surprisingly low in metropolitan areas.

As regards to low back pain of agricultural worker, there are many problems still as to a syndrom of “Nofusho” in rural medicine, a disease in ocupational medicine and clinic of orthopedic.
Agricultural worker who complained of low back pain varies with their country and farm products, and it tend to increase with adding to their age. Further, the female rate of low back pain showed slightly high tendency than the made rate, 8.5-12.5 % of male, 6.5-13.4 % of female always complained of low back pain.
According to the findings of roentogenographic examination of back bone, the deformed vertebrae was found clearly, especially, low back pain caused by a trauma of soft tissue and iscogenic pain showed in farmers. Therefor, it is necessary to be improved working posture and condition.
In comparrison with non-farmer, it is located in order of truck drivers. bus drivers and repairmen.

We encountered a patient with intractable panic disorder who responded extremely well to Ryukotsuto, a Kampo preparation. Beginning in March 2003, a 55-year-old female began to lose vigor and concentration, while developing palpitations and experiencing a rise in blood pressure (systolic pressure≥190mmHg) accompanied by sudden anxiety. When these symptoms became intense, she was brought to a hospital by ambulance. Although close examination revealed no abnormalities, on clinical diagnosis, however, autonomic imbalance was recognized. Despite treatment with antidepressants and minor tranquilizers, including selective serotonin reuptake inhibitors (SSRI), no improvement was observed. A series of medicinal Kampo preparations, prescribed one after another, also had no effect. For further treatment, she was referred to our hospital on July 22, 2005. At the first consultation, a diagnosis of panic disorder was made, according to the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV). Hon-Ton disease was suspected based on clinical findings, and Ryokeikansoto was prescribed as a decoction. However, no positive effects were observed after 1 week, while marked incompetence, forgetfulness, and depression were noted. Therefore, based on the results of a self-rating depression scale (SDS), a profile of mood states (POMS), and autonomic function tests, such as pupillary dynamics at the first consultation, panic disorder accompanied by extreme tension with depression was diagnosed. Consequently, her Kampo preparation was changed to Ryukotsuto. As a result, symptoms virtually disappeared and all western drugs were discontinued. Psychological tests, autonomic function tests, and her diagnostic scores for conditions of Ki, Ketsu, and Sui also improved. We conclude that Ryukotsuto may be an effective treatment for panic disorder accompanied by depression.
