Fluorescent whitening agents (FWAs) have been manufactured since 1950 in Japan. Now, they are used very widely in the fields of paper, textile, and detergent industries.Discussions were given to the results of medical surveys and studies on the safety of the FWAs derived particularly from diaminostilbene disulphonate.The FWAs can be considered to be safe both in chronic and acute toxicities.Further, possibility of the FWAs' contamination to human skin or table-wares from papers and textiles was examined.The results showed that the degrees of contamination were very small or negligible.As a conclusion, the FWAs are practically nontoxic even if they are taken into human bodies, though they can not migrate to human skin from papers or textiles containing the FWAs.

The present study was undertaken to examine the latent labyrinthine reflex and sensation to the linear acceleration in the human body and following results were obtained.1)A close relationship was recognized between the latent progressive reflex observed by electromyography in the human body, and the results obtained by the usual vestibular examination. 2) In the reflex to the linear acceleration, the frequency of its appearance was varied by altering the head position in the movement of the ups and downs on the frontal axis, but it was hardly varied by altering the head position right and left on the sgittal axis.3) As a result of the experiment in the human body, the sensitivity of the linear kinetic sensation in the vertical direction was found to be varied by lineal acceleration closed to the threshold of kinetic sensation, when the head posititon was altered on the frontal axis. 4) The results of these experiments indicated that the saccles otlith mainly acted for receiving the movement to the right and the left, while utricles otolith served to receive that to the upward and the downward, but both otoliths seemed to act mutually with duplicate or subsidiary function.5) The observation of the linear kinetic reflex might be applied in the clinical field of medicine as one of the test of vestibular function of human bodies. 6) In the experiment on rabbit, the labyrinthine muscle reflex to the linear acceleration was mainly observed to appeare in the flexor muscles of the extremities contralaterally. 7) The appearance of this reflex did not always require interposition of the cervical muscles.

The Annext Figures of the Arteries and veins (i. e. Fig. the 1st, 6th, and 8th,) were drawn after the vessels themselves Pasted and dryed, which were Diffected from Adult Human Bodies, and display’d on Tables now to be seen in the Repository of the Royal Society and are the Generous Present of John Evelyn, Esq; from whom l received the following Letter concerning them and other Tables of the Nerves, &c; to which I, have subjoyn’d a further account, &c.

Having been so large in my former instance, in my discourse on the joynted-worm , I intend to contract myself in this .

The most adequate screening test to find out the pathological state in stored blood donors was studied. In-patients of pulmonary tuberculosis and other various diseases were examined. The various properties of their blood elements and the organ functions were as follows: 1) Pathological properties were; 37.7% in hippuric acid systhesis, 65.5% in BSP test, 55.3% in zinc sulphate turbidity, 60.3% of γ-Gl quantity, 65.4% in A/G index, 56.7% in serum T-Ch (Total-cholesterin) quantity, 49.5% in total protein content, 63.7% in red corpuscule sedimentation 68.8% in Congored index, 48.1% in Thorn's adrenalin test, 36.4% in respiratory equivalent and 50% in lung power. 2) The examinations, which showed positive results above half, were serum T-Ch quantity, red corpuscle sedimentation, Congored index and lung power test etc. 3) From the results mentioned above, the examination of liver function, serum T-Ch quantity, red corpuscle sedimentation and Congored test etc. are significant to determine pathological states generally.

日本における修学旅行(学童)の目的がいかなるところにあろうとも,その疲労よりする事故の発生が云々されている今日,ここにかかる条件下における疲労度を測定し,客観的にその日程(日取)を決定する必要がある。 今回我々は学童を対象とする短期旅行(3泊4日)をその研究の一環としてとりあげた。 学童(約60名)を2群に分け,1群(A群)は早朝その旅行目的地に,他の1群(B群)夕刻同地に向わせ,両群における旅行疲労度を前記Vitality法(尿係数O/K3法)により観察し,つぎの結果を得た。 A群すなわち早朝出発群においては,すでに出発前において睡眠不足に由来するVitalityの低下(尿係数値の上昇)がうかがわれ,その旅行の進展とともに,さらにいちぢるしいものとなった。 すなわち,かかる学童を対象としての短期間の旅行においては学童を夜行にて出発させるが如き計画の方が早朝出発せしめるよりも条件が良いことがわかった。

Notwithstanding the general application of the learned in this age to anatomy, and the success wherewith they have cultivated it, there remain undoubtedly many considerable discoveries to be made, many useful organs to be detected, of great consequence to the right understanding of the animal deconomy.
