    The investigation of oligosaccharides obtained from the blood group-active glycolipid fractions indicated the presence of rather long carbohydrate chain.
    The following structures were proposed :
    H-active glycolipid :
    α-Fuc- (1→2) -β-Gal- (1→4) -β-GNAc- (1→3) -β-Gal-(1→4)-β-GNAc-(1→3)-β-Gal-(1→4)-Glc-ceramide
    A-active glycolipid :
    α-GalNAc-(1→3)-β-Gal-(1→4)-β-GNAc-(1→3) -β-Gal-(1→4)-β-GNAc-(1→3)-β-Gal-(1→4)-Glc-ceramide

    α-Fuc
    B-active glycolipid :

    Epidemiological and biochemical studies of chloramphenicol (CM) resistance were conducted by using the CM-resistant strains of Staphylococcus aureus which were isolated from clinical specimens. It was found that most of the CM-resistans strains carried quadruple or triple resistance with special reference to tetracycline, streptomycin, penicillin and sulfanilamide, indicating that the CM-resistant staphylococci were multiple-resistant.
    The CM-resistant strains of S.aureus isolated from clinical specimens were found to inactivate the drug but not an in vitro developed CM-resistant strain. The inactivated product was found to be 3-acetoxy-CM. Induction of CM resistance in Saureus was then studied by using several CM derivatives. It was found that the derivatives were classified into three groups; (1) high antibacterial activity and induction of CM resiatance, (2) low antibacterial activity and induction of CM resistance, and (3) loss of both activities. These results strongly suggeste that the mechanism ot CM resistance is different from that of the induction of CM resistance.

    This study aimed at obtaining the quantitative information about the functional state of the muscle contraction from surface EMG by means of spectral analysis, and revealing the relationship between the surface EMG and the NMU activity. The usefulness of this method was also examined in relation to its application to the motor function disorders. For the quantitative measurement of surface EMG and NMU impulse activity, auto-and cross-spectral analysis was performed by a general purpose digital computer (MC-1).
    The results were as follows;
    1) Changes of surface EMG due to the functional states of muscle contraction.
    In the normal subjects, strengthening of muscular contraction resulted in increase of higher frequency component of the spectra, and lower frequency component was dominant in the fatigued muscles. Coherence between two simultaneous EMG records from the same muscle tended to increase under the strong contraction or after the sustained contraction. In hemiparetic patients, the lower frequency component was dominant, and relatively lower value of coherence was obtained from the paretic muscles. In Parkinsonian patients, marked frequency shift of spectra to higher frequency and increase of coherence were observed during strengthening contraction, on the contrary, however, at the maximal contraction, the coherence was decreased.
    2) Relationship between the NMU discharges and surface EMG.
    In healthy subjects and Parkinsonian patients, lower coherence was obtained between the two EMG phenomena, when the dominant component of surface EMG was in higher frequency range (more than 30Hz). While the higher coherence, on the contrary, was detected, when lower component (10-20Hz) was dominant. In hemiparetic patients, paretic limb showed slightly lower coherence than normal side.
    These results were discussed from the aspects of the mass activity of NMU, and the surface EMG was considered as a useful indicator to characterize the functional states of muscle activities. Thus, appropriate frequency analytical data processing of the surface EMG was expected to be an effective tool for obtaining informations of the normal and abnormal motor functions.

    Employing the test method reported by Matumoto et al., which is a sort of measuring selective reaction time to the stimulus of light, the grades of the ability of quick action on 541 subjects (239 males, 17-65 years, 302 females, 17-61 years) were measured. The obtained results were the following :
    1. The full score of the ability of the individual subject was 10, and the score of the subject ranged from 0 to 10, the average score of the total subjects was 3.9±2.8, for the male subjects 5.9±2.4, for the female 2.3±1.9, but 70% of the subjects obtained the score between 2 and 5.
    2. The average score of the subjects under and above 40 years was 3.9±2.9 and 4.0±2.0 respectively.
    3. The average score of the boy and girl students of a high school was 6.3±2.1 and 1.6±1.2 respectively.
    4. It was found that the score of the test of individual subject did not contradict the motion ability of the subject observed in daily life and in the sport.

    Employing the test method of the ability for the quick action of the individual subject reported by Matumoto et al., which is a sort of measuring the selective reaction time to the visual stimulus, the test was carried out on the subjects (22 males, 19-61 y) during drinking alcoholic beverage (sake or beer). The subjects drank the wine with their own pitch with some cups, and the test was carried out every 30 minutes from the commencement of the drinking, and at the same time the total amount of sake (or beer) drunk till the time was recorded. The obtained results were in the following.
    1) With increase of the amount of wine drunk, the score of the test varied in two ways, namely it decreased with increase of the amount of sake (or beer) simply or at first increased and then decreased.
    2) The amount of wine which decreased the score of the subject to the half of the normal state was measured. It ranged from 150 cc to 1050 cc of sake, but for great many of the subjects it was ca. 500 cc.
    3) From the results of the test, it was confirmed that the change of the ability for the quick action in get drunk state was different from subject to subject, namely it could not be assumed merely as the amount of the drunk sake (or beer).
