ジャコウネズミ(スンクス)の指におけるパチニー小体の分布と形態-予報-
ジャコウネズミ(スンクス)足指におけるパチニー小体の形態と分布を光学顕微鏡および電子顕微鏡を用いて調べた.パチニー小体は長径約260μm,幅径約130μmの卵円体ないし楕円体である.形態学的にはネコやヒトの関節包にみられる小型の小体に類似する.周縁は10層程度の神経周膜細胞の層板(外棍)からなり,その内部には30ないし40の細胞質層板からなる内棍と神経終末部が含まれる.パチニー小体は指の屈筋腱と指骨の間の深部結合組織中に両側性に局在し,他の部位には認められない.位置関係から,これらのパチニー小体は指屈筋腱の緊張に曝されていると考えられる.すなわち,ヒトなどの比較的大型のほ乳類と同様に,ジャコウネズミにおいても,指のパチニー小体は体肢の筋活動の反射的制御に関与していることが示唆される.The distribution and morphology of the digital Pacinian corpuscles in the laboratory house musk shrew, Suncus murinus, were examined by light and electron microscopes. The Pacinian corpuscles occurred bilaterally along the digital nerves in the connective tissue between the flexor digitorum tendons and palmar aspects of the phalanges. They were oval or ellipsoidal in shape and were small, bearing structural resemblance to those occurring in the articular capsules of the cat and man. The outer core of each corpuscle is comprised of approximately 10 layers of perineural lamellae. Because the digital Pacinian corpuscles are exposed to tendinous activity, they may be involved in the regulation of muscle tonus of the limbs in the house musk shrew
先天性表皮水疱症に対する理学療法-症例報告-
先天性表皮水疱症は厚生省による特定疾患治療研究対象疾患で,いわゆる「難病」指定疾患である.表皮水疱症では,日常生活で外力が加わる部位に反復する水疱を臨床症状の主体とし,軽微な外力による水疱発生が基本であるが,病変活発な時期では特に誘因なく発生する場合もあるという.著者らは,7年間にわたって表皮水疱症接合部型の男児に理学療法を実施してきた.体表面が外界と接触するということは乳幼児の感覚一運動学習過程において必要不可欠な体験であるにもかかわらず,水疱発生によってそのことが阻害され結果的に運動発達の遅れを呈した.今回,問題を残しながらも普通小学校への就学ゴールに達したので,これまでの理学療法経過と若干の考察を加えて報告する.The purpose of this paper is to report on the course and physical therapy for epidermolysis bullosa. Epidermolysis bullosa is designated as a specific rare disease by the Ministry of Health and Welfare. The clinical feature is repeated blister formation that occurs following mechanical stimulation in daily living. The blisters may occur without cause especially at an active time of morbid change, although these are actually caused by slight stimulations. It is absolutely indispensable for sensori-motor learning in the baby that the body surface make contact with the environment. Motor learning is based on having experiences with the interaction between perception and motor. However, it is guessed that no comfort was experienced by the patient via sensory information from the skin. It is probable that he experienced of continuous pain and pruritus, felt as itching of the entire body. Therefore, it is inferred that biased perceptions would be generated and learned. In addition, blisters, erosions, and markedly fragile skin were actually aggravated by sensory inputs made to facilitate developmental intervention. Therapeutic exercise for the patient has been going on since four months from birth, but the patient has been continuing to exhibit retarded motor development. However, the patient was able to enter school normally in spite of having a few problems at present
ペルーの人工変形頭蓋正中矢状面輪郭における若干の顔面角について
ペルー人男性の前頭後頭型人工変形頭蓋における頭蓋型と,正中矢状面輪郭上の歯槽性突顎に関連する若干の角について調べた.変形頭蓋は非常に大きな頭蓋示数を有するが,頭蓋モズルスは非変形頭蓋との間に有意差がなかった.Basion (Ba)-Nasion (Na)-Prosthion (Pr)角とBa-Na-Subspinale (Ss)角における両頭蓋間の差は有意であった.これに対し,Na-Pr線,Na-Ss線とフランクフルト面(FHP)のなす角度の差は有意でなかった.また,Na-Ba線とFHPとのなす角に有意差が認められた.これらの結果から人工変形はNa-Ba線の位置変化をもたらすが,歯槽性突顎の形態には影響を与えないことが示唆される.Three principal cranial dimensions and six angles on sagittal cranial profile related with facial prognathism, between artificially front-occipital deformed and undeformed Peruvian skulls were examined. The deformed skull group was characterized by a shorter and wider neurocranial vault. Angular analyses suggested that the skull deformation caused displacement of the basion-nasion line. However, the significant difference in the facial prognathism between the deformed and undeformed skulls could not be confirmed in this craniogeometric study
解剖実習体の膝関節にみられた円板状外側半月の一例について-特に関節内靱帯との関係-
65歳男性遺体の右膝に見いだされた円板状外側半月を観察し,特に関節内付属靱帯との関係を記載した.円板状外側半月は比較的幅広く,脛骨の外側顆上関節面をほぼ完全に被い,肉眼的観察およびX線撮影ではその損傷や石灰化などの異常は見られなかった.本例では,全体的に半月の固定に関係する靱帯の発達が良好であった.すなわち,半月の前角と後角は靱帯を介して強固に脛骨に付着し,さらに,強い半月横靱帯が内・外側半月の前部を連結していた.後方では外側半月後角から起こる太い後半月大腿靱帯が認められた.加えて,内側・外側半月の前角から起こり前十字靱帯に合流する靱帯小束が認められたが,これらは半月の前部固定に関与すると考えられた.The right knee, from a male cadaver aged 65, with discoid lateral meniscus was carefully dissected. The meniscus and its anatomical relationships with some associated ligaments of the knee are described. The discoid meniscus was a wide structure covering nearly the articular surface of the tibia and was almost intact macroscopically. Neither meniscal calcification nor ossification was demonstrated by radiography. There were strong transverse ligament, solid attachments from both anterior and posterior horns to the tibia, distinct posterior menisco-femoral ligament, and ligamentous slips from both anterior horns of the medial and lateral menisci to the anterior cruciate ligament. The knee anatomy was characterized by the well-development attachment system of the menisci. The medial meniscus was anatomically normal
Human Blood Feeding Activity of Female Hybrids between Culex pipiens pipiens and Culex pipiens quinquefasciatus(Diptera: Culicidae)
Human blood feeding activity was examined in females of hybrids between Culex pipiens pipiens and Culex pipiens quinquefasciatus during long photoperiod at 25℃. Blood feeding rates of hybrids were lower than in Culex pipiens quinquefasciatus and Culex pipiens pallens, and higher than in Culex pipiens pipiens, because no females fed on human blood in Culex pipiens pipiens
Tendons of the M. flexor digitorum superficialis in the hand of the house musk shrew, Suncus murinus
スンクス(ジャコウネズミ)の手における浅指屈筋の腱について
スンクスにおける筋系のまとまった解剖学的研究はSharmaおよび磯村によってなされている.両研究の間で解剖所見の一致しない浅指屈筋の指に至る腱の配列について,連続セロイジン切片から若干の観察を行った.その結果はSharmaの解剖所見を支持する.There are some discrepancies in the anatomical findings for the tendons of the M. flexor digitorum superficialis of Suncus murinus reported in systematic studies conducted by Sharma (1958) and Isomura (1985). In particular, the reports differ in description of extension of the tendons of the M. flexor digitorum superficialis to the digits of the hand. The present anatomical study describes these tendons, and its findings clearly support the description set forth by Sharma
Pacinian Corpuscles in the Digits of the House Musk Shrew (Suncus murinus)-Preliminary note-
富山県氷見市泊洞穴出土人骨(泊洞穴人)の歯の大きさから見た人類学的位置
富山県氷見市泊洞穴から出土した人骨(泊洞穴人)は、そのフッ素含有量が完新世前期から更新世末期に比定され、形態学的研究もこれをほぼ裏づけている。本研究は歯の大きさの観点から、泊洞穴人の人類学的な位置をさらに明確にするために行われた。歯の計測値に基づくペンロースの距離の主座標分析から得られた結果は、泊洞穴人が少なくとも完新世前期以前ないしは縄文時代以前に属する、とする従来の報告を支持している。Skeletal remains discovered in 1967 and 1972 at Tomari cave in Himi city,Toyama prefecture, Japan (Tomari cave man) has been provisionally attributed to the earlier Holocene or to the later Late Pleistocene according to physicochemical and osteological studies. The present study was designed to give Tomari cave man a more precise anthropological position from the viewpoint of tooth size, using principal coordinate analysis of Penrose\u27s size and shape distances among age populations. The analyses by both distances support the previous studies that Tomari cave man belongs to the age since the neolithic Jomon period or earlier Holocene
