Obesity in children is a serious public health problem, and TV viewing is considered a potential risk factor. Since, however, no relevant association studies have been conducted in Japan, we evaluated the association between TV viewing and obesity using a population-based study conducted in a Japanese town. All 616 preschool children in the town were enrolled in February 2008, and a self-administered questionnaire to collect children's and parents' characteristics was sent to the parents. We dichotomized the time spent TV viewing and evaluated associations by logistic regression using a "less than 2h" category as a reference. The questionnaire was collected from 476 participants (77.3%), of whom 449 were available for the final analyses. Among them, 26.9% of preschool children reported 2 or more hours of TV viewing per day and 8.2% were defined as obese. In logistic regression analyses, there was no positive association in unadjusted (odds ratio [OR]1.11, 95% confidence interval [95% CI]:0.50-2.49) or adjusted models for exclusively breastfed status, sleep duration, or maternal factors (OR1.11, 95% CI:0.50-2.51). We also found no positive association between TV viewing and overweight status, possibly owing to the influence of social environment, low statistical power, or misclassification.

1) Three different types of muscle fibers were clearly distinguished in the intercostal muscles and the diaphragm of human, cat and rat by histochemical demonstration of oxidative enzymes, phosphorylase and glycogen. 2) The intercostal muscles and diaphragm each presented dissimilar patterns of the muscle fibers. The diaphragm did not show any definite correlation between the diameter and the histochemical reaction of muscle fibers but its red fibers indicated a more intense uptake of Nitro-BT formazan deposits in the subsarcolemmal region. In this conection, the relationship between the motor innervation and histochemical evaluation of the diaphragm was described. 3) Phosphorylase and glycogen showed reciprocal reactions to the oxidative enzyme activity. They were generally high in large fibers but low in small fibers, and moderate in intermediate fibers.

For predicting median date or incidence rate in the prevalence of japanese encephalitis, the authors considered the 34 factors; namely, the climate, latitude, longitude, and date showing immunological positivity of hemoagglutination inhibiting reaction on 50% the number of swine, etc. To make the mean square residual the smallest which yields, in the case of calculating with the multiple regression equation, the most important and meritorious factors were selected from the factors mentioned above by the voluntary selection rule devised by us. Multiple regression equations were formulated for them. To predict the median date in the prevalence of japanese encephalitis in whole japan, we found that the three factors, i. e. the amount of rainfall in April, the average temperature in March and HI positive rate of swine till the end of july, were essential. And for the foreseeing of incidence rate in Okayama Prefecture, factors concerning mosquitoes were added; this resulted in the useful two factors, namely, common logarithm of the total number of Culex tritaeniorhynchus till july 20th and the rainfall in June.

The rats which received the repeated intra peritoneal or intravenous　injections of methyl palmitate showed a marked depressed phagocytic activity　of the RES as shown by the clearance test with radioactive iron as　well as by histological observations and a significantly suppressed antibody　formation against the challenge by BSA.　Differing from the cases of the blockade of the RES made by PVP or　radiogold, the injection of methyl palmitate did not result in any injurious　effect on the lymph follicles of lymph nodes and spleen and the plasma　cells proliferation as revealed by the histological observation. Histochemical observations of iron phagocytosis of the RES done by　Perls stain revealed that methyl palmitate　suppressed the phagocytic activity　of the Kupffer cells of the liver dramatically and also suppressed the　phagocytic activity of the sinus-lining cells in spleen to a lesser degree.　The result indicates that the injection of methyl palmitate attacks the phagocytic　function of the RES selectively and induces the reduced immune　response of the organism without giving any damages to the proliferation of immunologically com petent cells.　The fact suggests that the RES lowered in their phagocytic activity　fails to produce the informational substance for immune　response, showing　a lower level in the antibody formation even in the presence of antigen　and proliferating immunologically competent cells.

Die Autoren berichten uber die guten Behandlungsmoglichkeiten in der Praxis bei verschiedenen peripheren venosen Durchblutungsstorungen bei Erkrankungen der Bewegungsapparate, bei leichteren Fallen von arteriellen DurchblutungsstOrungen und bei einigen Fallen von Hirnblutungen mit Vasotonin und Vasotonin-forte und auch in vitro-Blutgerinnungsuntersuchungen. Bei den erwahnten Fallen kann man die therapeutische Wirkung noch mit Vasotonin-forte-Salbe gut unterstutzen. Die Autoren konnen nachweisen, daB Extr. Arnicae insbesonder in dem Vasotonin-forte die hamodynamische und die blutgerinnungshemmende Wirkung von extr. Aesculi Hippercastani gut verstairkt.

For the investigation of iron metabolism in the intestinal mucosa in various　blood diseases, intestinal biopsy (duodenum) was performed on 10 healthy controls　and 35 cases with various blood diseases. The following are　the results　of the studies on distribution of stainable　iron, amounts of non-hemin iron in the　biopsied materials, and iron uptake of the intestinal epithelial cells.　1) An evaluation of distribution of stainable iron by Berlin　blue reaction　showed none or very mild degree, if any,　inhealthy controls, an increase in　aplastic anemia,　pernicious anemia, some of leukemias and in iron deficiency anemia following iron therapy, and a decrease in　idiopathic hypochromic anemia, anchylostomiasis anemia,　anemia with cancer, myxedema, hemolytic anemia,　and in　some of leukemias. Some of anemia with cancer, however,　showed an　increase of a certain degree. In iron absorption tests, no changes were found other than a very mild increase in aplastic anemia. 2) Non-hemin iron was 70-112γ/g in healthy controls, increased in aplastic anemia approximately to 100-200γ/g, ranging 40-130γ/g in leukemia, and decreased in idiopathic hypochromic anemia and in anemia with cancer ranging 30-60γ/g and 30-50γ/g respectively. Amounts of non-hemin iron and serum iron or sideroblasts show a fair correlation. The fractionation of nonhemin iron in aplastic anemia didn't show any difference in relationship of each fraction from healthy controls despite the increased amount in the former. 3) A radioautographic evaluation of iron uptake by intestinal epithelium was performed by our device for evaluation of intestinal absorption capacity. The iron uptake was mild in healthy controls, almost none in aplastic anemia, and marked in iron deficiency anemia where it was decreased approximately to the level of healthy controls following iron therapy. 4) The intestinal tissue iron showed a series of changes similar to those of iron present in the serum or erythroblasts, and the non-hemin iron in the intestinal mucosa is inversely correlated with iron uptake of epithelium and is considered to regulate the absorption according to its amount.

1. An attempt has been made to find the diagnostic criteria for early gastric cancer. It is most important to detect the evidences or suspected features of the malignant growth in incipient stage in order to attain the radical cure by surgical operation. 2. Twelve patients with early gastric cancer (groups A and B) were selected out of 476 patients who had undergone gastrectomy during the past three years in the Okayama Saiseikai General Hospital. The other 6 patients in the "precancerous group" (group C) were also studied, who had abnormal epithelial proliferation in the resected stomach membrane during the same period. 3. The processes of discovery of early cancer have been described. Fairly precise diagnosis can be made in the mucosal carcinoma, but it is not in the ulcer-carcinoma. It was generally difficult to estimate the degree of the malignancy and the extension of the growth preoperatively. 4. The details of the diagnostic aids are as follows. i. Negative occult blood of stool does not always mean the definite diagnostic aid. ii. The malignant gastric change may occur even in non-anacidity. Further investigations should be followed up on gastric ulcer patients if malignant alteration is under the consideration. iii. Minor roentgenological findings, such as the absence or irregularity of mucosal folds, rigid and/or overlapped contour, localized absence or decrease of the peristaltic waves and absence or bow-shaped deformity of the angulus, are of important significance. Such changes should be minutely sought for by X-ray film examination. iv. On gastroscopy and gastrocamera photography, such changes as erosion or irregular granular thickening of the membrane with abnormal reddening and edematous appearance, irregularity of ulcer edge, uneven swelling on ulcer margin with reddening and unsharpness of the edge of adherent coat on ulcer floor, must be noted in the early gastric cancer. v. It is not safe to leave a patient having stomach ulceration under a mere conservative management because it is often quite difficult to dissolve the question of malignancy of the lesion with all sorts of examinations. vi. So far as clinical examinations have indicated malignancy, histological examination must be carried out immediately at the time of operation, even when malignant lesion is absent in inspection and palpation on the exposure of the stomach. vii. On the gross observation of the resected stomach, a particular attention must be paid to erosion, depression or atrophy, irregular granular thickening and abnormal reddening on the restricted areas of the mucosal surface.
