Isolated spikes appeared immediately after the injection of FeCl(2) solution in ECoGs of the cortex near the injection site and the contralateral homotopic cortex. The injection of FeCl(2) solution produced different electrocorticographic features in which the frequency of isolated spikes was dominant on the side ipsilateral or contralateral to the injection site or nearly equal on the two sides. The spike frequency increased up to 30 to 50 days after the injection, and then was almost constant in most of the rats up to 90 days after the injection. In rats showing nearly equal spike activity on the two sides, there was a tendency for the spike frequency to decrease gradually after 30 to 50 days. Most of the spike and slow wave complexes appeared bilaterally one month or more after the injection in rats in which the isolated spike activity was dominant on the side ipsilateral to the injection site or nearly equal on the two sides. The proportion of rats showing spike and slow wave complexes increased steeply until three months after the injection, and reached 36% of all the FeCl(2) solution-injected rats six months after the injection. In ECoGs of these rats, isolated spikes were also detected. In rats showing dominant spike activity on either side of the cortex, most of spikes appeared unilaterally, while in rats showing nearly equal spike activity on the two sides and those showing spike and slow wave complexes, the frequency of almost synchronous spikes on both sides was higher than that of unilateral spikes. In rats showing dominant spike activity on the side contralateral to the injection site, SEPs recorded at the cortex near the injection site were devoid of the initial positive deflection and were monophasic. They were biphasic in other FeCl(2) solution-injected rats. In rats showing only isolated spikes, abnormal behavior was seldom observed, and convulsion thresholds were lowered. In most of the rats showing spike and slow wave complexes, head nodding was observed. The induction and development of epileptic focus by FeCl(2) solution are discussed. en-copyright= kn-copyright= en-aut-name=NishidaNobuyoshi en-aut-sei=Nishida en-aut-mei=Nobuyoshi kn-aut-name=西田宜可 kn-aut-sei=西田 kn-aut-mei=宜可 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第一生理学教室 en-keyword=鉄塩誘導てんかん kn-keyword=鉄塩誘導てんかん en-keyword=ラット大脳皮質 kn-keyword=ラット大脳皮質 en-keyword=脳波 kn-keyword=脳波 en-keyword=体性感覚誘発電位 kn-keyword=体性感覚誘発電位 en-keyword=けいれん kn-keyword=けいれん en-keyword=閾値 kn-keyword=閾値 END start-ver=1.4 cd-journal=joma no-vol=97 cd-vols= no-issue=1-2 article-no= start-page=127 end-page=147 dt-received= dt-revised= dt-accepted= dt-pub-year=1985 dt-pub=19850225 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on the cyclic AMP-generating system of cerebral cortex with iron-induced epileptic focus kn-title=鉄塩誘導てんかん性大脳皮質のサイクリックAMP合成系に関する研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The cyclic AMP contents of cortical slices after incubation with or without agents such as norepinephrine were determined in four areas of rat cerebral cortex in which FeCl(2) solution was injected into the unilateral sensorimotor cortex to induce an epileptic focus. Norepinephrine, isoproterenol and phenylephrine elevated the cyclic AMP levels of cortical slices 4- to 7-fold, 2- to 4-fold and 1.5- to 3-fold, respectively. The elicitation of cyclic AMP accumulation by norepinephrine was inhibited by 30 to 60% with phentolamine and 65 to 80% with propranolol. 8-Phenyltheophylline almost completely inhibited the elicitation of cyclic AMP accumulation by a norepinephrine-propranolol combination but not by a norepinephrine-phentolamine combination. In anterior cortical areas of rats in which the appearance of isolated spikes in electrocorticograms was dominant either ipsilaterally or contralaterally to the injection site 8 to 10 days after the injection of FeCl(2) solution, the elevated levels of cyclic AMP elicited by norepinephrine, isoproterenol and a norepinephrine-phentolamine combination were higher on the side of dominant spike activity than on the other. In anterior cortical areas of rats showing dominant spike activity on either side of the cortex 31 to 60 days after the injection, the elevated levels of cyclic AMP elicited by norepinephrine and phenylephrine were lower on the dominant side than on the other. In anterior cortical areas of rats showing nearly equal spike activity on the two sides 31 to 60 days after the injection, the elevated levels of cyclic AMP elicited by norepinephrine, isoproterenol and a norepinephrine-phentolamine combination were higher on the side ipsilateral to the injection site than on the other. In these rats, a similar regional difference in the norepinephrine-elicited accumulation of cyclic AMP was detected 19 to 21 days after the injection. In anterior and posterior cortical areas of rats in which the appearance of spike and slow wave complexes as well as isolated spikes were detected 31 to 60 days after the injection, the elevated levels of cyclic AMP elicited by norepinephrine, isoproterenol, phenylephrine and combinations of norepinephrine and phentolamine or propranolol were higher on the side ipsilateral to the injection site than on the other. The tendency for the norepinephrine-elicited accumulation of cyclic AMP to be related to the epileptic discharge patterns in rats 61 to 90 days after the injection was similar to that in rats 31 to 60 days after the injection. The regional differences in cyclic AMP contents of incubated cortical slices are discussed with regard to the neurochemical process of iron-induced epilepsy. en-copyright= kn-copyright= en-aut-name=YasuharaHiromichi en-aut-sei=Yasuhara en-aut-mei=Hiromichi kn-aut-name=安原弘通 kn-aut-sei=安原 kn-aut-mei=弘通 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第一生理学教室 en-keyword=サイクリックAMP kn-keyword=サイクリックAMP en-keyword=ノルエピネフリン kn-keyword=ノルエピネフリン en-keyword=ラット大脳皮質 kn-keyword=ラット大脳皮質 en-keyword=切片 kn-keyword=切片 en-keyword=鉄塩誘導てんかん kn-keyword=鉄塩誘導てんかん END start-ver=1.4 cd-journal=joma no-vol=97 cd-vols= no-issue=1-2 article-no= start-page=113 end-page=126 dt-received= dt-revised= dt-accepted= dt-pub-year=1985 dt-pub=19850225 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Rehabilitation of bilateral lower extremity amputees kn-title=岡山県における両下肢切断者の実態調査 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Impairments and disabilities of forty-two bilateral lower extremity amputees resistered at the Okayama Prefectural Rehabilitation Center from 1967 to 1983 were analysed. Sixty-nine percent of the amputation were related to trauma. The incidence of amputation due to vascular disorders were lower in Okayama than in Western countries. Sixty percent of the cases ranged from twenty to sixty years of age. The average age of the amputees was lower than that in Western coutries. In eighty-seven percent of the amputees, skin erosion and sweating were major complaints. Therefore, the development of sweat-absorbable sockets is an important project. Lock or safety knee joints were used for A/K prostheses in order to obtain good knee stability. Of six high level amputees, three were confined to a wheel chair. Thirty-nine amputees were able to walk with prostheses. One third of the cases had no job after prosthetic training. Eighty-one percent of all cases were married. The rate of employment and marriage was much higher than in Western countries. From these findings, it can be said that bilateral lower extremity amputees are rehabilitated fairly well in Okayama. en-copyright= kn-copyright= en-aut-name=SugiharaToshihiro en-aut-sei=Sugihara en-aut-mei=Toshihiro kn-aut-name=杉原俊弘 kn-aut-sei=杉原 kn-aut-mei=俊弘 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部整形外科学教室 en-keyword=amputation kn-keyword=amputation en-keyword=bilateral lower extremities kn-keyword=bilateral lower extremities en-keyword=prosthesis kn-keyword=prosthesis END start-ver=1.4 cd-journal=joma no-vol=97 cd-vols= no-issue=1-2 article-no= start-page=101 end-page=112 dt-received= dt-revised= dt-accepted= dt-pub-year=1985 dt-pub=19850225 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Early clinical experience with NMR-CT kn-title=NMR-CTの初期臨床経験 en-subtitle= kn-subtitle= en-abstract= kn-abstract=We have used an NMR-CT scanner clinically since August 1 1984.

From our clinical experience during the past four months, we describe the advantages and disadvantages of NMR-CT. The advantages are that: 1) it is possible to recognize blood vessels without contrast materials and to evaluate the blood flow 2) there are neither bone nor air artifacts, and 3) it is possible to get the tomogram in any direction. The disadvantages are that: 1) the examination time is very long, 2) there are artifacts from ferromagnetic substances placed in the body, 3) when palse sequence is changed, images are different from each other, and 4) because of respiratory motion artifacts, the images of the chest and abdomen are inferior to those of other parts of the body. en-copyright= kn-copyright= en-aut-name=JojaIkuo en-aut-sei=Joja en-aut-mei=Ikuo kn-aut-name=上者郁夫 kn-aut-sei=上者 kn-aut-mei=郁夫 aut-affil-num=1 ORCID= en-aut-name=SatoNobuo en-aut-sei=Sato en-aut-mei=Nobuo kn-aut-name=佐藤伸夫 kn-aut-sei=佐藤 kn-aut-mei=伸夫 aut-affil-num=2 ORCID= en-aut-name=FujishimaMamoru en-aut-sei=Fujishima en-aut-mei=Mamoru kn-aut-name=藤島護 kn-aut-sei=藤島 kn-aut-mei=護 aut-affil-num=3 ORCID= en-aut-name=KajiMitsumasa en-aut-sei=Kaji en-aut-mei=Mitsumasa kn-aut-name=加地充昌 kn-aut-sei=加地 kn-aut-mei=充昌 aut-affil-num=4 ORCID= en-aut-name=TogamiIzumi en-aut-sei=Togami en-aut-mei=Izumi kn-aut-name=戸上泉 kn-aut-sei=戸上 kn-aut-mei=泉 aut-affil-num=5 ORCID= en-aut-name=NiiyaHarutaka en-aut-sei=Niiya en-aut-mei=Harutaka kn-aut-name=新屋晴孝 kn-aut-sei=新屋 kn-aut-mei=晴孝 aut-affil-num=6 ORCID= en-aut-name=ShirakamiToshiaki en-aut-sei=Shirakami en-aut-mei=Toshiaki kn-aut-name=白神敏明 kn-aut-sei=白神 kn-aut-mei=敏明 aut-affil-num=7 ORCID= en-aut-name=YamamotoHiromichi en-aut-sei=Yamamoto en-aut-mei=Hiromichi kn-aut-name=山本博道 kn-aut-sei=山本 kn-aut-mei=博道 aut-affil-num=8 ORCID= en-aut-name=TakedaYoshihiro en-aut-sei=Takeda en-aut-mei=Yoshihiro kn-aut-name=竹田芳弘 kn-aut-sei=竹田 kn-aut-mei=芳弘 aut-affil-num=9 ORCID= en-aut-name=KimotoShin en-aut-sei=Kimoto en-aut-mei=Shin kn-aut-name=木本真 kn-aut-sei=木本 kn-aut-mei=真 aut-affil-num=10 ORCID= en-aut-name=HashimotoKeiji en-aut-sei=Hashimoto en-aut-mei=Keiji kn-aut-name=橋本啓二 kn-aut-sei=橋本 kn-aut-mei=啓二 aut-affil-num=11 ORCID= en-aut-name=MorimotoSetsuo en-aut-sei=Morimoto en-aut-mei=Setsuo kn-aut-name=森本節夫 kn-aut-sei=森本 kn-aut-mei=節夫 aut-affil-num=12 ORCID= en-aut-name=SugitaKatsuhiko en-aut-sei=Sugita en-aut-mei=Katsuhiko kn-aut-name=杉田勝彦 kn-aut-sei=杉田 kn-aut-mei=勝彦 aut-affil-num=13 ORCID= en-aut-name=HirakiYoshio en-aut-sei=Hiraki en-aut-mei=Yoshio kn-aut-name=平木祥夫 kn-aut-sei=平木 kn-aut-mei=祥夫 aut-affil-num=14 ORCID= en-aut-name=AonoKaname en-aut-sei=Aono en-aut-mei=Kaname kn-aut-name=青野要 kn-aut-sei=青野 kn-aut-mei=要 aut-affil-num=15 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部放射線医学教室 affil-num=2 en-affil= kn-affil=岡山大学医学部放射線医学教室 affil-num=3 en-affil= kn-affil=岡山大学医学部放射線医学教室 affil-num=4 en-affil= kn-affil=岡山大学医学部放射線医学教室 affil-num=5 en-affil= kn-affil=岡山大学医学部放射線医学教室 affil-num=6 en-affil= kn-affil=岡山大学医学部放射線医学教室 affil-num=7 en-affil= kn-affil=岡山大学医学部放射線医学教室 affil-num=8 en-affil= kn-affil=岡山大学医学部放射線医学教室 affil-num=9 en-affil= kn-affil=岡山大学医学部放射線医学教室 affil-num=10 en-affil= kn-affil=岡山大学医学部放射線医学教室 affil-num=11 en-affil= kn-affil=岡山大学医学部放射線医学教室 affil-num=12 en-affil= kn-affil=岡山大学医学部放射線医学教室 affil-num=13 en-affil= kn-affil=岡山大学医学部放射線医学教室 affil-num=14 en-affil= kn-affil=岡山大学医学部放射線医学教室 affil-num=15 en-affil= kn-affil=岡山大学医学部放射線医学教室 en-keyword=nucler magnetic resonance kn-keyword=nucler magnetic resonance en-keyword=spin echo kn-keyword=spin echo en-keyword=inversion recovery kn-keyword=inversion recovery en-keyword=T(1) relaxation time kn-keyword=T(1) relaxation time en-keyword=T(2) relaxation time kn-keyword=T(2) relaxation time END start-ver=1.4 cd-journal=joma no-vol=97 cd-vols= no-issue=1-2 article-no= start-page=91 end-page=99 dt-received= dt-revised= dt-accepted= dt-pub-year=1985 dt-pub=19850225 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Difficulty in determining the extent of metastatic lesions in bone scintigrams: A case report. kn-title=骨転移放射線治療において骨シンチグラムで病巣範囲決定に問題があった2症例の検討 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Radiation therapy for bone metastasis of malignant tumors is useful for reducing pain and is often used.

In addition to the direct effect of inflammation of the respiratory tract, the released IFN is also suspected to be an important factor in the aggravation of bronchoconstriction in bronchial asthma. The effects of IFN on morphological changes of basophils from round to pear shape and histamine release from basophils were analyzed to clarify the role of IFN in bronchial asthma. IFN alone did not affect these parameters in either healthy subjects or asthmatic patients. As a model of the basic bronchial asthma reaction, anti-IgE was added to basophils with and without IFN preincubation. The IgE mediated reaction was enhanced with IFN in basophils from atopic and non-atopic asthma patients. Furthermore, the enhancement of histamine release was observed in atopic asthma, more significantly than in non-atopic asthma. The IgG mediated reaction of basophils is considered to play a role in some asthmatic patients. IFN apparently increased reactive basophils of non-atopic asthma patients in the IgG mediated reaction. On the other hand, the histamine release from basophils was so minimal that the effect of IFN on the IgG mediated reaction was not clearly detected. While the mechanism of enhancement is still controversial, the suppressive effect of histamine release by isoproterenol in addition to anti-IgE suggest the regulation of reactive basophils by the cyclic AMP concentration. en-copyright= kn-copyright= en-aut-name=TamuraNaohiko en-aut-sei=Tamura en-aut-mei=Naohiko kn-aut-name=田村尚彦 kn-aut-sei=田村 kn-aut-mei=尚彦 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第2内科学教室 en-keyword=Interferon kn-keyword=Interferon en-keyword=Reactive basophil kn-keyword=Reactive basophil en-keyword=Histamine release kn-keyword=Histamine release en-keyword=Bronchial asthma kn-keyword=Bronchial asthma en-keyword=cyclic AMP kn-keyword=cyclic AMP END start-ver=1.4 cd-journal=joma no-vol=97 cd-vols= no-issue=1-2 article-no= start-page=65 end-page=77 dt-received= dt-revised= dt-accepted= dt-pub-year=1985 dt-pub=19850225 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The role of lymphocytes in bronchial asthma I.

T-cell subsets were determined by immunofluorescent microscopy using OKT monoclonal antibodies: T3 for pan T-cells, T4 for helper/inducer cells, and T8 for suppressor/cytotoxic cells. In these analyses, patients with bronchial asthma were classified according to the background of atopy, onset age, and duration of asthmatic symptoms. Decreased T4 percent and T4/T8 ratio were found in patients with non-atopic asthma, patients with onset later than 40 years of age, and patients with a duration of less than 5 years. Although corticosteroids are known to decrease the T4 percent and T4/T8 ratio in peripheral blood lymphocytes, their effect on T-cell subsets in BALF is not well known. In this study, the T4 percent and T4/T8 ratio in BALF were found to be lower in patients with corticosteroids than in patients without corticosteroids and in healthy subjects. These results indicate that an immunological abnormality which might be related to the pathogenesis of bronchial asthma exists in particular groups of asthmatic patients. en-copyright= kn-copyright= en-aut-name=TamuraNaohiko en-aut-sei=Tamura en-aut-mei=Naohiko kn-aut-name=田村尚彦 kn-aut-sei=田村 kn-aut-mei=尚彦 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二内科学教室 en-keyword=Bronchial asthma kn-keyword=Bronchial asthma en-keyword=Bronchoalveolar lavage kn-keyword=Bronchoalveolar lavage en-keyword=リンパ球subset kn-keyword=リンパ球subset END start-ver=1.4 cd-journal=joma no-vol=97 cd-vols= no-issue=1-2 article-no= start-page=55 end-page=63 dt-received= dt-revised= dt-accepted= dt-pub-year=1985 dt-pub=19850225 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Serum ferritin levels in hospital patients kn-title=各種疾患における血清フェリチン値の臨床的評価 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Serum ferritin levels were determined in 75 hematologic, 1205 malignant, and 538 benign diseases.

We have experimented on the degree of the dilution and CT-No to decide the optimum consistency of gastrografin for the diagnosis of pancreatic disease. Statistical analysis of the results show the optimum dilution of gastrografin to be 1.5%. en-copyright= kn-copyright= en-aut-name=MatsushimaKishio en-aut-sei=Matsushima en-aut-mei=Kishio kn-aut-name=松島紀志夫 kn-aut-sei=松島 kn-aut-mei=紀志夫 aut-affil-num=1 ORCID= en-aut-name=MimuraSeiichi en-aut-sei=Mimura en-aut-mei=Seiichi kn-aut-name=三村誠一 kn-aut-sei=三村 kn-aut-mei=誠一 aut-affil-num=2 ORCID= en-aut-name=TaharaSeiji en-aut-sei=Tahara en-aut-mei=Seiji kn-aut-name=田原誠司 kn-aut-sei=田原 kn-aut-mei=誠司 aut-affil-num=3 ORCID= en-aut-name=KitayamaTakuichi en-aut-sei=Kitayama en-aut-mei=Takuichi kn-aut-name=北山卓一 kn-aut-sei=北山 kn-aut-mei=卓一 aut-affil-num=4 ORCID= en-aut-name=InamuraKeiji en-aut-sei=Inamura en-aut-mei=Keiji kn-aut-name=稲村圭司 kn-aut-sei=稲村 kn-aut-mei=圭司 aut-affil-num=5 ORCID= en-aut-name=MikamiYasutaka en-aut-sei=Mikami en-aut-mei=Yasutaka kn-aut-name=三上泰隆 kn-aut-sei=三上 kn-aut-mei=泰隆 aut-affil-num=6 ORCID= en-aut-name=HashimotoKeiji en-aut-sei=Hashimoto en-aut-mei=Keiji kn-aut-name=橋本敬二 kn-aut-sei=橋本 kn-aut-mei=敬二 aut-affil-num=7 ORCID= en-aut-name=HirakiYoshio en-aut-sei=Hiraki en-aut-mei=Yoshio kn-aut-name=平木祥夫 kn-aut-sei=平木 kn-aut-mei=祥夫 aut-affil-num=8 ORCID= en-aut-name=AonoKaname en-aut-sei=Aono en-aut-mei=Kaname kn-aut-name=青野要 kn-aut-sei=青野 kn-aut-mei=要 aut-affil-num=9 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部附属病院中央放射線部 affil-num=2 en-affil= kn-affil=岡山大学医学部附属病院中央放射線部 affil-num=3 en-affil= kn-affil=岡山大学医学部附属病院中央放射線部 affil-num=4 en-affil= kn-affil=岡山大学医学部附属病院中央放射線部 affil-num=5 en-affil= kn-affil=岡山大学医学部附属病院中央放射線部 affil-num=6 en-affil= kn-affil=岡山大学医学部附属病院中央放射線部 affil-num=7 en-affil= kn-affil=岡山大学医学部放射線医学教室 affil-num=8 en-affil= kn-affil=岡山大学医学部放射線医学教室 affil-num=9 en-affil= kn-affil=岡山大学医学部放射線医学教室 en-keyword=Pancreas CT kn-keyword=Pancreas CT en-keyword=希釈造影剤濃度 kn-keyword=希釈造影剤濃度 en-keyword=視覚評価の統計処理 kn-keyword=視覚評価の統計処理 END start-ver=1.4 cd-journal=joma no-vol=97 cd-vols= no-issue=1-2 article-no= start-page=39 end-page=45 dt-received= dt-revised= dt-accepted= dt-pub-year=1985 dt-pub=19850225 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Speech Correction Class at Izushi Primary School ―History and recent problems― kn-title=出石小学校ことばの教室15年 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Fifteen years have passed since the speech correction class was established at Izushi Primary School in Okayama.

In addition, changes in regional brain GABA content after gabaculine administration were determined. Intra-hippocampal administration of gabaculine has a dose-dependent anticonvulasnt effect on kindled amygdaloid seizure. The anticonvulsant effect of gabaculine (0.92μg/2μl) was observed within only 24 hours of the gabaculine administration. Further, a significant increase in the GABA level in the ventral mibdrain region was observed within only 24 hours of the gabaculine (0.92μg/2μl) administration. The suppression of amygdaloid kindled seizures after intra-hippocampal administration of gabaculine may be due to the elevation of the GABA level in the ventral midbrain rather than in the hippocampus. en-copyright= kn-copyright= en-aut-name=OgawaToshihiko en-aut-sei=Ogawa en-aut-mei=Toshihiko kn-aut-name=小川俊彦 kn-aut-sei=小川 kn-aut-mei=俊彦 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部神経精神医学教室 en-keyword=amygdaloid kindling kn-keyword=amygdaloid kindling en-keyword=GABA kn-keyword=GABA en-keyword=gabaculine kn-keyword=gabaculine en-keyword=hippocampus kn-keyword=hippocampus en-keyword=ventral midbrain kn-keyword=ventral midbrain END start-ver=1.4 cd-journal=joma no-vol=97 cd-vols= no-issue=1-2 article-no= start-page=19 end-page=27 dt-received= dt-revised= dt-accepted= dt-pub-year=1985 dt-pub=19850225 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Rapid classification of staphylococci by using lysostaphin sensitivity kn-title=Lysostaphin感受性によるStaphylococcus属の迅速鑑別について en-subtitle= kn-subtitle= en-abstract= kn-abstract=The lysostaphin sensitivity test of staphylococci is a reliable classification method based on the differences in peptidoglycan compositions. Lysostaphin sensitive staphylococci are identified as S. aureus. In this paper, we stueied the applicability of this test to the rapid classification of clinically isolated staphylococci. Staphylococci were exposed to 2μg of lysostaphin per ml at 37℃ for 15 min. The sensitivity was decided by a turbidity check and gram-stain check. There were no differences between the check methods. Sixty-four strains of 99 clinical isolates were sensitive and consisted of 59 S. aureus. strains and 5 non-S. aureus strains (S. simulans 4; S. capitis 1). The 35 strains which were lysostaphin-insensitive were non-S. aureus as identified by coagulase and other biological sensitivity tests. The lysostaphin sensitivity test might be a very reliable and rapid method for the identification of S. aureus. en-copyright= kn-copyright= en-aut-name=AkatsukaKazuya en-aut-sei=Akatsuka en-aut-mei=Kazuya kn-aut-name=赤塚和也 kn-aut-sei=赤塚 kn-aut-mei=和也 aut-affil-num=1 ORCID= en-aut-name=OtaKimi en-aut-sei=Ota en-aut-mei=Kimi kn-aut-name=大田紀美 kn-aut-sei=大田 kn-aut-mei=紀美 aut-affil-num=2 ORCID= en-aut-name=KayaharaJunko en-aut-sei=Kayahara en-aut-mei=Junko kn-aut-name=茅原淳子 kn-aut-sei=茅原 kn-aut-mei=淳子 aut-affil-num=3 ORCID= en-aut-name=HiramotoHiroko en-aut-sei=Hiramoto en-aut-mei=Hiroko kn-aut-name=平本浩子 kn-aut-sei=平本 kn-aut-mei=浩子 aut-affil-num=4 ORCID= en-aut-name=FujimuraHiroko en-aut-sei=Fujimura en-aut-mei=Hiroko kn-aut-name=藤村弘子 kn-aut-sei=藤村 kn-aut-mei=弘子 aut-affil-num=5 ORCID= en-aut-name=KanemasaYasuhiro en-aut-sei=Kanemasa en-aut-mei=Yasuhiro kn-aut-name=金政泰弘 kn-aut-sei=金政 kn-aut-mei=泰弘 aut-affil-num=6 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部附属臨床検査技師学校 affil-num=2 en-affil= kn-affil=岡山大学医学部附属臨床検査技師学校 affil-num=3 en-affil= kn-affil=岡山大学医学部附属臨床検査技師学校 affil-num=4 en-affil= kn-affil=岡山大学医学部附属臨床検査技師学校 affil-num=5 en-affil= kn-affil=岡山大学医学部附属臨床検査技師学校 affil-num=6 en-affil= kn-affil=岡山大学医学部細菌学教室 en-keyword=Lysostaphin kn-keyword=Lysostaphin en-keyword=Staphylococcus kn-keyword=Staphylococcus en-keyword=Gram stain kn-keyword=Gram stain en-keyword=Spectrophotometer kn-keyword=Spectrophotometer END start-ver=1.4 cd-journal=joma no-vol=97 cd-vols= no-issue=1-2 article-no= start-page=11 end-page=17 dt-received= dt-revised= dt-accepted= dt-pub-year=1985 dt-pub=19850225 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Study of Insulin Metabolism in Liver Injury II. Insulin Secretion in Rats with Acute and Chronic Liver Injury kn-title=肝障害時の血中インスリン動態に関する研究　第2編　急性および慢性肝障害ラットにおける糖負荷後血中インスリン反応と単離膵ラ氏島のインスリン分泌 en-subtitle= kn-subtitle= en-abstract= kn-abstract=In liver diseases, it has been pointed out that pancreatic hypersecretion of insulin is one of the factors which induces hyperreaction of serum insulin after oral glucose loading. Insulin secretion may change according to the stage of liver injury. To address this problem, the glucose tolerance test (GTT) and perifusion of the islets of Langerhans were performed in rats with carbon tetrachloride (CCl(4))-induced liver injury. On the day after administration of CCl(4), ΣIRI increased after GTT, but decreased after perifusion. On the 3rd and 7th days, ΣIRI after GTT and perifusion was normal. These results suggest that in the acute stage of acute liver injury, pancreatic secretion of insulin was reduced and hyperreaction of serum insulin to GTT was probably due to decreased insulin degradation. In the convalescent stage, insulin secretion was normal. During the 3 to 6 weeks of CCl(4) administration, ΣIRI in GTT and perifusion rats did not differ significantly from that of controls. But in the 12th week, ΣIRI after GTT and perifusion increased remarkably. These results suggest that in the early stage of chronic liver injury, pancreatic secretion of insulin does not change, but in the cirrhotic stage, insulin secretion increases, causing hyperreaction of insulin after GTT. en-copyright= kn-copyright= en-aut-name=NakataKenichi en-aut-sei=Nakata en-aut-mei=Kenichi kn-aut-name=中田憲一 kn-aut-sei=中田 kn-aut-mei=憲一 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第一内科 en-keyword=肝疾患 kn-keyword=肝疾患 en-keyword=インスリン kn-keyword=インスリン en-keyword=糖負荷試験 kn-keyword=糖負荷試験 en-keyword=単離膵ラ氏島 kn-keyword=単離膵ラ氏島 en-keyword=周辺灌流 kn-keyword=周辺灌流 END start-ver=1.4 cd-journal=joma no-vol=97 cd-vols= no-issue=1-2 article-no= start-page=1 end-page=9 dt-received= dt-revised= dt-accepted= dt-pub-year=1985 dt-pub=19850225 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Study of Insulin Metabolism in Liver Injury I. Insulin Secretion and Degradation in Patients with Various Liver Diseases kn-title=肝障害時の血中インスリン動態に関する研究　第1編　肝疾患時の糖負荷後血中高インスリン反応の機序 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Glucose intolerance and insulin hyperreaction after oral glucose loading have been reported in various liver diseases. Pancreatic hypersecretion and decreased hepatic degradation of insulin have been pointed out as explanation of the high peripheral insulin levels. To clarify the effects of and correlation between these two factors in various stages of liver diseases, serum immunoreactive insulin (IRI), connecting peptide immunoreactivity (CPR) and blood glucose (BG) were determined after 50-g oral glucose tolerance tests. In the acute stage of acute hepatitis, ΣCPR, ΣCPR/ΣBG and ΣIRI/ΣCPR were high, suggesting that both increased secretion and decreased degradation of insulin were responsible for the high peripheral insulin levels. In the convalescent stage, ΣCPR, ΣCPR/ΣBG and ΣIRI/ΣCPR were normal. In chronic hepatitis, increased ΣCPR and normal ΣCPR/ΣBG were observed. ΣIRI/ΣCPR was low in chronic persistent hepatitis, but high in chronic aggressive hepatitis. Thus, in chronic persistent hepatitis, hypersecretion of insulin to compensate for the elevated blood glucose was induced and insulin degradation did not decrease, so that normal peripheral insulin levels were maintained. In chronic aggressive hepatitis, increased secretion and decreased degradation of insulin were responsible for the higher peripheral insulin levels. In compensated liver cirrhosis, ΣCPR and ΣCPR/ΣBG were high, but ΣIRI/ΣCPR was normal. In the decompensated state, ΣCPR was high, ΣCPR/ΣBG normal and ΣIRI/ΣCPR high, suggesting that increased insulin secretion was the major cause of the high peripheral insulin levels in compensated liver cirrhosis. In the decompensated state, both increased secretion and decreased degradation of insulin were responsible for the high peripheral insulin levels. These data indicate that insulin secretion from the pancreas and insulin degradation in the liver are influenced by the stage of the liver disease. en-copyright= kn-copyright= en-aut-name=NakataKenichi en-aut-sei=Nakata en-aut-mei=Kenichi kn-aut-name=中田憲一 kn-aut-sei=中田 kn-aut-mei=憲一 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第一内科 en-keyword=肝疾患 kn-keyword=肝疾患 en-keyword=インスリン kn-keyword=インスリン en-keyword=Cペプチド kn-keyword=Cペプチド en-keyword=糖負荷試験 kn-keyword=糖負荷試験 END
