The M. rectus abdominis of man was examined, noting the cross-sectional area of , the number of muscle fibers per sq. mm., the total number of muscle fibers, the thickness of muscle fibers and the occupational area of muscle fibers in cross-section of the right abdominal rectus specimen of adults. The results obtained were compared with the previously reported pertinent data of the other muscles.
1. The average values (M) of each data of the M. rectus abdominis examined was 205 mm² in cross-sectional area, 172, 327 in total number of muscle fibers, 1151 μ² in muscle fiber size and 91% in occupational ratio of muscle fibers.
2. Those muscle specimens which have large cross-sectional area tend to be inferior in number of muscle fibers and to be superior in total number of muscle fibers, size of muscle fibers and occupational ratio of muscle fibers than the specimens which have small cross-sectional area. But the muscle specimens with broader cross-sectional area do not always have a larger size and larger density of muscle fiber while some one of them do contain rich interfibrous connective tissue.
3. As to the relationship of the size of muscle fiber to cross-sectional area of , a positive correlation was found to exist, and its of number of muscle fibers per sq. mm. to those showed a tendency of negative correlation.
4. Comparing the myofibrous organization of Rectus abdominis with the other muscles, we found that the cross-sectional area and the total number of this muscle was smaller than that of adductor longus and biceps brachii, and that the size of muscle fibers of this muscle was larger than that of the other muscles except adductor longus.

This report describes a case of brachial biceps with bilaterally abnormal bundles of origin and insertion which was encountered during the dessection of an 86 year-old Japanese female cadaver in the anatomical laboratory of Kanazawa Medical University. There was an accessory head and tail in the brachial biceps of the right upper arm. The accessory head (Caput tertium) arose from the fibrous capsule of the shoulder joint and pectoralis major tendon. In caput tertium, the head was attached to the internal front part of the of caput breve. The accessory tail arose from the medial rear part of the of caput breve. This tail was separated into the medial and lateral tendons. The medial tendon was mainly attached to the caput ulnae in the pronator teres and the fibrous capsule of the elbow joint. The lateral tendon surrounded the rear side of the biceps tendon. There were an accessory head and tail in the brachial biceps of the left upper arm. The accessory head (Caput tertium) arose from the fibrous capsule of the shoulder joint and pectoralis major tendon. This head was attached to the front part of the junction of the two ordinary heads of the brachial biceps. The accessory tail arose from the medial rear part of the in the caput breve and was separated into the medial and lateral tendons. The medial tendon was attached to the medial side of the bicipital aponeurosis. The lateral tendon was attached mainly to the caput ulnae of the pronator teres, and the medial intermuscular septum and the fibrous capsule of the elbow joint.

The feather mite Pseudalloptinus milvulinus (Trouessart, 1884) was collected from feathers of the Black Kite Milvus migrans (Boddaert, 1783) in Ishikawa Prefecture, Japan, in 2019. The identification of this mite was based on the form and arrangement of setae on the idiosoma and aggenital region. This study is the first report of this mite species and the genus Pseudalloptinus Dubinin, 1956 in Japan.

帯状疱疹に対するRo-8181の有効性, 安全性および有用性を検討するため, ヒト血清アルブミンを対照薬として, 二重盲検比較試験を行つた。皮膚症状の観察項目別の改善率では, 水疱·膿疱において投与開始後5日目でRo-8181群70%, placebo群50%で, 両群間に差(p<0.05)が認められた。皮膚症状改善度の推移を著明改善以上の症例についてみると, 投与開始後4日目の著明改善率はRo-8181群8%, placebo群0%であり, Fisherの直接計算法で両群間に差(p<0.05)が認められた。また, 投与開始後5日目の著明改善率はRo-8181群15%, placebo群3%であり, κ² 検定で両群間に差(p<0.05)が認められた。主治医による有効性の判定ではU検定でRo-8181群が優れている傾向が認められた。主治医による安全性の判定では副作用発現率がRo-8181群83%, placebo群14%であり, U検定で両群間に差(p<0.001)が認められた。主治医による有用性の判定ではU検定で両群間に差は認められなかつた。以上の結果より, 帯状疱疹に対し, Ro-8181は皮疹のうち水疱·膿疱に対して有効であり, 主治医判定でも有効性が認められたが, 安全性については本薬剤の耐薬性が示されたものの副作用の発現率が高かつたため, 有用性は高くないと考えられた。

The Japan Society for Occupational Health (JSOH) recommends the Occupational Exposure Limits (OELs) as reference values for preventing adverse health effects on workers caused by occupational exposure to chemical substances, continuous or intermittent noise, impulsive or impact noise, heat stress, cold stress, whole-body vibration, hand-arm vibration and time-varying electric, magnetic and electromagnetic fields and ultraviolet and ionizing radiation.

Intracerebral injection of vegetative myxamoebae of strains of Polysphondylium pallidum caused 80 to 100% mortality in mice, whereas a 30 to 50% mortality occurred with strains of Dictyostelium giganteum and D. mucoroides. Death is attributable to an unidentified toxic factor. Histopathologically a giant cell formation was seen in the spleen of mice. This cell was different from Langerhan's or foreign body giant cell. Rats injected intracerebrally behaved similarly. Intranasal instillation of myxamoebae in guinea pigs caused transient pneumonia. Myxamoebae do not multiply in the brain tissues of mice or rats, or in the lungs of guinea pigs.
Intranasal instillation of vegetative myxamoebae is less pathogenic than free living amoebae like Hartmanella culbertsoni, H. rhysodes, Naegleria sp. (Culbertson strain HB-1), or Naegleria aerobia.

The nd Annual Meeting of Japan Society for Science Education (JSSE) was held on July 29-31, 1998 at Tokyo Gakugei University in western suburb of Tokyo with about 290 registrants under the main theme of "Towards Implementation of Science Curriculum for Construction of Creation and Symbiosis." Number of papers over 210 were presented in both main sessions and general presentations. There were two symposiums, one lecture, one forum, one international forum, one workshop, three sessions of themes set by the steering committee and ten sessions of themes set independently by members of JSSE in main sessions. Also, there were many other general presentations. Many papers were presented coping with the main theme. They were a lecture related to learning and creativity based on advance of brain, and many presentations related to symbiosis such as relation between in-door and out-door school activities, school based research activities such as curriculum development, and way of finding new methodology of research on classroom, consistency of curriculum through elementary to high school, pre-service teacher education, and so on. Contents of claims and discussions in every presentation in main sessions are summarized in this paper.

A financial market is a diversified dynamical system with many constraints, and price movements are modeled in terms of the micro properties of each transactions and the macro properties of dynamical systems. These two properties must be bridged by the multiplicity. The model forcuses on the size of tick and the number of transactions with the price movement compared with the previous transctions and explains stochastic nature of short-term volatilities and persistently stable long-term volatilities as a results of unique behaviour of heterogeneous market participants.
