Broiler chicks were reared on either wet litter or dry litter to compare the development of footpad dermatitis (FPD). Broilers reared on wet litter first developed FPD at 14 days of age. Their FPD scores increased sharply after 21 days of age, reaching 2.92 at 42 days. In broilers reared on dry litter, FPD was first observed at 28 days of age, and the FPD score was only 0.70 at 42 days. When 21- or 28-day-old broilers that had been reared on wet litter and had developed FPD were moved to dry litter, the progression of FPD was suppressed or delayed. These results suggest that reducing litter moisture is effective in preventing FPD and suppressing disease progression.

In order to investigate the actual state of cancer within the jurisdiction of the Kawagoe Helth Centre of the Saitama Prefecture, we have visited all the 110 hospitals and clinics within the jurisdiction, under the cooperation of the Doctors' Ass'n., and the Health Centre. We have not only inquired of the doctors, but have also gone through the protocols of the patients who have come during the investigation period, and we have chosen those who were diagnosed as cancer or malignant ulcer, making our observations according to sex, age, and disease types. We have calculated the death rate by comparing the contraction percentage of cancer, the prevalence rate, and the death certificate ; and have compared it with the figures of various parts of the U.S.A., and the Miyagi, Okayama, and Saitama Prefectures. Furthermore, the monthly survival rate was obtained, and the drawing up of basic data was attempted in order to devise measures of the prevention of cancer.

Amyloid β protein (Aβ) self-assembles into insoluble fibrils, and forms the senile plaques associated with Alzheimer’s disease. 3,3′,4′,5′-Tetrahydroxyflavone, a synthetic analogue of the natural flavonoid fisetin, has been found to potently inhibit Aβ fibril formation. In the present study, we investigated how inhibition of Aβ fibril formation by this flavonoid affects Aβ conformation and neurotoxicity. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) analysis of Aβ1-42 (20 µM) incubated with or without 3,3′,4′,5′-tetrahydroxyflavone demonstrated that 3,3′,4′,5′-tetrahydroxyflavone (100 µM) rapidly caused formation of atypical Aβ conformers, which appeared as a very broad, smear-like band in the high molecular weight region and were distinguishable from soluble Aβ oligomers or mature Aβ fibrils. Transmission electron microscopy (TEM) revealed that large spherical Aβ aggregates were preferentially formed in the presence of 3,3′,4′,5′-tetrahydroxyflavone. The SDS-resistant, smear-like band on SDS-PAGE and the large spherical aggregates in TEM both disappeared after heat treatment (100°C, 10 min). Furthermore, a neurotoxicity assay with cultured rat hippocampal neurons demonstrated that Aβ incubated with 3,3′,4′,5′-tetrahydroxyflavone was significantly less toxic than Aβ incubated without the flavonoid. These results suggest that the newly synthesized fisetin analogue 3,3′,4′,5′-tetrahydroxyflavone directly produces atypical, large Aβ aggregates and reduces Aβ toxicity.

This study examined how people can handle the multiple audience problem of self-presentation (Fleming, 1994), when faced with two or more audiences while simultaneously wanting each audience to form or maintain a different impression of the presenter. In the laboratory, female participants had a brief conversation with either an opposite-sex (male) or a same-sex (female) confederate. The results showed that when no one else observed the conversation, the participants presented themselves as physically attractive to the opposite-sex more than to the same-sex audience. On the other hand, when another same-sex individual was observing the conversation, the participants presented themselves to the opposite-sex audience as less physically attractive but more socially desirable and friendly. The importance of this compensatory self-enhancement strategy in the multiple-audience situation is discussed.

The textural properties of noodles boiled and kept in a refrigerator for 0,1,2 and 4 hours and 1 day were investigated by a breaking test. The curve of the breaking stress was analyzed by difference calculus to indicate the degree of the change in hardness while chewing the noodles. The change in texture, or koshi, of the noodles after boiling could be quantitatively expressed by the change in slope of the breaking stress curve with a strain of 0.01. A multiple-regression analysis of the noodle texture was performed on the score from the sensory evaluation and the breaking test results. The breaking energy and the discrepancy in the slope of the breaking stress curve for the noodles were selected as independent variables, and the multiple correlation coefficient was 0.997.

To produce tomato fruits with 6% average Brix without decreasing yield, we investigated the effect of moderate salinity stress on Brix and yield in a single-truss, high-density tomato production system. Because tomato fruit development can be predicted from cumulative temperature, we also assessed cumulative temperature after anthesis as a potential indicator for determining the starting points of salinity stress treatments. When transverse diameters of the first fruit reached 4 cm (i.e., early increase treatment) or the first fruits were at the mature green stage (i.e., late increase treatment), nutrient solution electrical conductivity was slowly increased until the breaker stage from 1.8 dS·m−1 to 6.0 dS·m−1. Plants subjected to the late increase treatment produced tomato fruits with Brix values of 6% without reductions in marketable yield. We also increased nutrient solution electrical conductivity based on cumulative temperature after anthesis and found that early-treated plants produced tomatoes with higher Brix levels and yields than late-treated plants. In summary, moderate salinity stress to avoid excessive stress on plants increased sugar concentrations without decreasing fruit yield and resulted in tomato fruits with average Brix of about 6% when nutrient solution electrical conductivity was increased at a rate of 0.1 dS·m−1·day−1. Because seasonal differences in cumulative temperature influence the appropriate timing of salinity stress applications, further study is needed to optimize year-round growth under moderate salinity stress in single truss, high-density tomato production systems.

In order to gain an insight into the relationship between the molecular structure and the semiconductor characteristics of highly π-extended heteroarene-based organic semiconductors, three structural isomers of dinaphthothieno[3,2-b]thiophenes with C2h symmetry were investigated. Of these, two isomers, dinaphtho[2,1-b:2′,1′-f ]thieno[3,2-b]thiophene (2) and dinaphtho[1,2-b:1′,2′-f ]thieno[3,2-b]thiophene (3), were newly synthesized, characterized, and utilized as active semiconducting layers in organic field-effect transistors (FETs). Detailed investigation of the physicochemical properties of 2 and 3, together with another isomer, dinaphtho[2,3-b:2′,3′-f ]thieno[3,2-b]thiophene (1), indicated that the electronic structures of the three isomers are fairly different from each other despite having the same molecular formula and the same aromatic constituents. Comparison of the molecular arrangements in the crystals elucidated by X-ray structural analysis implied that the molecular shape and the thus-induced favorable intermolecular interactions play important roles in determining the entire molecular arrangement. The characteristics of 2- and 3-based FETs with maximum field-effect mobilities (μFET s) of 10−3–10−2 cm2 V−1 s−1 were inferior to those of 1-based FETs with μFET s up to 3.0 cm2 V−1 s−1. The inferior characteristics of 2- and 3-based devices were due to film morphology as elucidated by atomic force microscopy (AFM) and supported by theoretical calculations of electronic structure in the solid state. Together, the results indicate that the molecular structure and shape, even for similar heteroarenes with the same molecular formula and symmetry, are important parameters to determine the solid-state properties of organic semiconductors.

Ampullary tumors are diagnosed by endoscopic biopsy of the ampulla of Vater. We encountered a rare case of acute pancreatitis following endoscopic biopsy of the ampulla. A 53-year-old man referred to our hospital for detailed examination of a suspected tumor of the ampulla of Vater. We conducted endoscopic biopsy from the ampulla. He developed severe abdominal pain four hours after the procedure. The serum amylase and serum lipase were elevated and abdominal computed tomography (CT) revealed pancreatic enlargement and diffuse stranding of the peri-pancreatic fat, compatible with the findings of acute pancreatitis. We diagnosed the patient as having acute pancreatitis caused by endoscopic biopsy of the ampulla of Vater. Conservative therapy improved his condition, however, a large pancreatic walled-off necrosis (WON) developed. Therefore, we performed endoscopic ultrasonography (EUS)-guided cyst drainage on the 74th day after admission. The WON diminished gradually in size and the symptoms disappeared, and the patient was discharged in good physical condition on the 137th day after admission. In this case, the ampullary biopsy may have caused mucosal edema or intraductal hematoma, resulting in pancreatic duct obstruction. It is important for endoscopists both to be aware of this potential complication following endoscopic biopsy of the ampulla and to inform the patients about possible complications of this procedure.

飼育下でアカネズミ(Apodemus speciosus)の自然交配による繁殖を誘導できる飼育交配手法を検討した.巣穴環境を擬似的に再現することで繁殖が誘導できるとの作業仮説のもと,ケージ内の床敷きを覆うように板を設置した中蓋あり飼育ケージを考案した.季節的な環境要因の影響を考慮するため,自然環境温度・自然光周期条件である半野外飼育施設において中蓋あり条件と中蓋なし条件で交配実験を行った.さらに環境条件が一定の室内飼育施設においても中蓋あり条件で交配実験を行った.その結果,半野外飼育施設の中蓋なし条件で雌個体の妊娠が確認されたのは11個体中1個体で1例のみだったのに対し,同施設での中蓋あり条件では9個体中4個体で6例の繁殖が誘導された.さらに室内飼育施設での中蓋あり条件では10個体中4個体で12例の繁殖が誘導でき,繁殖したペアの多くが複数回の繁殖を行った.半野外飼育施設の結果から,飼育ケージに中蓋を設置し疑似巣穴環境を再現することで,飼育下においてアカネズミの繁殖が誘導できることが示唆された.さらに繁殖の誘導が困難とされてきた室内飼育条件においても,繁殖に適した物理環境条件下であれば中蓋を用いることで繁殖を誘導できることが明らかとなった.これらのことから,飼育下における本種の繁殖誘導には飼育ケージに中蓋を設置するという簡便な手法が有効であると考えられる.

The common octopus, Octopus (Octopus) vulgaris LAMARCK, an important commercial species in Japan, are captured by means of the octopus pot, the hand line and the spear along the east coast of Boso Peninsula, Chiba Pref. (Fig. 1 and Table 1). The writer has made a biological study of the stock of this animal, using the statistic data of the octopus fisheries and based upon the number of specimens taken in Uchiura Bay near Kominato. The results obtained are summarized as follows; (1) It is believed that the octopus stock may be composed of two groups, one inhabiting the coast of Boso Peninsula throughout the year, the other migrating from the north to this district in winter (Figs. 2-5). (2) The maturation phase of the octopus is shown by the gonad index (R) as given in the following formula; R=G. W.×102/[B. W.-(G. W.+F. W.)], where G. W. denotes the gonad weight, F. W. the total weight of digestive organ contents, and B. W. denoting body weight. The relation between gonad index and maturity scale of the female octopus is shown in Table 2. (3) The breeding season is from March to November, and the biological minimum size is about 40cm in the male, 40-50cm in the female (Fig. 6). (4) The monthly increase in the rate of body weight deduced from the body composition (Fig. 7 and Table 3) and the length-weight relationship (Fig. 7 and Table 3) is 0.100 during from March to August, 0.180 from June to December. (5) It may be a reasonable assumption that the immigrant winter group breed during the first breeding season following the migration and that the newly hatched population will increase the available fishing stock from April to July of the following year. (6) Diminishing rate of the octopus stock is estimated by Dr. Tauti's method (1956) as 1-2% per day, 5-8% five days, 8-9% ten days and 13% per month (Table 4). Moreover, the diminishing rate per month is obtained by another Dr. Tauti's method ('53) as being 11%. (7) Judging from the diminishing rate caused by fishing, it may be said that the catch efficiency of the octopus pot is greater than that of the hand line.
