JOURNAL FREE ACCESSRecently, Dziewiatkowski, Boström and others (1) studied on the metabolism of S35 labelled sodium sulfate in vitro and in vivo. They found that, when a tracer dose of S35 as sulfate is given to an experimental animal, most of the radioactive sulfate is rapidly excreted, only a small fraction being retained in the tissues, mainly cartilage, bone and bone marrow and that most of the radioactive sulfur in these tissues are deposited as ester sulfate in chondroitinsulfuric acid.It is well known (2) that cortisone inhibits the formation of granulation tissue which has a synthetic capacity of chondroitinsulfuric acid. Layton (3) and Boström et al. (4) demonstrated by use of isotope tracer method that cortisone inhibited the synthesis of chondroitinsulfuric acid in embryonic and wound tissues.In our institute, it was found that placenta plasma (5), suspension of cold-stored human placenta in a normal saline solution, was remarkably efficacious to the proliferative diseases of connective tissue. It may be, therefore, inevitably necessary to investigate the effect of placenta plasma on the metabolism of chondroitinsulfuric acid in connective tissue.In this work, the authors studied on the effect of placenta plasma and cortisone on the utilization of S35 labelled sulfate by various tissues of mice and on the elimination of radioactive sulfur from their tissues. And the difference of the effect on sulfate exchange between them was investigated.View full abstractDownload PDF (512K) -

JOURNAL FREE ACCESSRecently the semiconductor called by the name of thermistor which has the large negative thermal coefficient has been applied in the wide extent of many scientific fields (1), and in the medical field there are various applications such as a thermometer, a blood flow meter and others. This is the report concerning with a trial production of the thermistor thermometer for measuring the temperature of the living body, especially of the very small region of body, as one of these applications.This paper was reported at the 6th Nishi-Nihon Physiological Conference in October 1955.View full abstractDownload PDF (282K) -

JOURNAL FREE ACCESSThe use of eggs in solid media for tubercle bacilli have been widespread since the introduction of Dorset's medium in 1902. In the media of Petroff, Petragnani, Loewenstein, and Oka-Katakura eggs especially egg yolks are still one of indispensable components. Neverthless, only a few reports to elucidate constituents of egg yolk which promote the growth of tubercle bacilli have been published. Hirsch (1954) (1) studied on this problem and reported that a growth promoting substance was present in the nonsaponifiable portion of the egg yolk solids soluble in diethyl ether and this substance was identified as cholestrol.We have engaged in the study on effects of digested egg yolk on the growth of tubercle bacilli since 1950, and in 1953 Ishida, one of the present authors, reported in Japanese that digested egg yolk had a remarkably stimulating effect on the growth of tubercle bacilli and the essentials of those growth promoting substances were phospholipids and amino acids.View full abstractDownload PDF (11027K) -

JOURNAL FREE ACCESSThe beneficial effects of egg yolk on the growth of Mycobacterium tuberculosis have been widely recognized for a long time. However, as far the effect of egg white is concerned no report has been published.The present paper deals with the addition of digested egg white to the fluid media for tubercle bacilli, and with its effects on the growth of tubercle bacilli.View full abstractDownload PDF (8831K) -

JOURNAL FREE ACCESSIt is surely of importance to estimate the numbers of living bacilli in a suspension of tubercle bacilli. Neverthless, the accurate calculation method of living tubercle bacilli has not been developed, since there are much difficulties in culculating tubercle bacilli by pour-plate method, which is employed widely for culculation of the numbers of ordinary living bacilli. As is known, it is very difficult to let tubercle bacilli grow in the depth of solid media, and evaporation of solid medium poured in Petri dish is inevitable for a long period cultivation of tubercle bacilli.The purpose of the present report is to dissolve the difficulties above mentioned, by using the Kirchner agar medium containing some growth promoting substances for tubercle bacilli, and by employing scotch cellulose tape for prevention of drying up of the solid media.View full abstractDownload PDF (6344K) -

JOURNAL FREE ACCESSThe muscle spindle consists of a number of intrafusal striated muscle fibers, which are different from the ordinary motor or extrafusal muscle fibers in several ways. In the mammalian, the intrafusal muscle fibers are considered to be innervated by the small motor nerve fibers. In the frog, however, it has been known that the skeletal muscle contains so-called ‘slow’ muscle fibers which receive their innervations from the small motor nerve fibers. The close analogy between the mammalian small-nerve spindle system and the frog small-nerve tonus system have been suggested by Kufller & Gerard (1), and recently emphasized by Kuflier and Vaughan Williams (2). It is significant that the frog nerve spindle system is not analogical to the mammalian nerve spindle system. Katz (3) found that the frog intrafusal muscle fibers receive their innervation from the ordinary large motor nerve fibers which also supply the extrafusal muscle fibers.The purpose of the present experiment is to record intracellularly the membrane potential changes of the intrafusal muscle fibers by applying nerve stimulations and to clarify the mode of neuro-muscular transmission in the frog nerve spindle system .View full abstractDownload PDF (5643K)
