On the early diagnosis of congenital dislocation of the hip joint a number of ways have been studied and tried clinically or roentgenologically but none of them are satisfactory and so it is the most important problem to us today to establish the complete way of the diagnosis of it.
By means of arthrography of the hip joints I examined 238 infants in the earlier half of suckling age who were diagnosed as suspicious condition or congenital dislocation of the hip joints by clinical pictures and roetgenographs. Those arthrograms were classified into seven types and compared with the clinical signs, namely the position of a limb and abduction test, and lateral displacement of femoral upper end and acetabular angle in roentgenograph, and as the result such conclusions were gained as follows.
1) The adductioncontracture of the dislocated limb was odserved both at the flexion and the extension position of the limb and tended to be prominent in the case of great dislocation. Increase of the outward rotation of the dislocated limb in extension was seen mainly in some cases of great dislocation, while decrease of it was seen in many cases.
2) In many cases of slight dislocation, the restriction of abduction was relatively small and showed the tendency to increase as the degree of dislocation became great. The click of the dislocated limb at the abduction test was able to be fell only in the case of great dislocation, and in the serious cases half or more than half of them could feel it.
3) Iino's indcx showing the degree of lateral displacement of femoral upper end was inclined to increase as the degree of dislocation became great. The index of all the cases of great dislocation was over normal limit, but the index of a normal hip joint and that of a slight dislocated one of ten showed the same value and it was difficult to distinguish them.
4) In the classification of the ilium morphologically by the ratio of height and width such results were gained as follows. In the case of wide ilium the normal acetabular angle showed a small value, so that in the case of great dislocation it was relatively small. In the case of narrow ilium the normal range of acetabular angle increased and so the acetabular angle of dislocation also tended to increase. It is the most important thing to consider the form of ilium in the measurement of the acetabular angle in the diagnosis of congenital dislocation of the hip joint.

1. A strain of Bacillus cereus was isolated from the soil which produced an enzyme acting on water-soluble Le^a substance and group OLe (a+b-) red cells. The enzyme preparation also contains A-decomposing enzyme, but not O(H) -, Le^b-and B-decomposing enzymes. Decomposition of Le^a activity of Le^a substance and Le (a + b-) red cells with this enzyme resulted in the enhancement of the cross-reactivity of Le^a substance and Le (a+b-) red cells with anti-pneumococci Type XIV chicken serum.
2. These enzymes were found in a fraction which precipitated at 30-60% ammonium sulfate saturation of bacterial autolysate. By means of DEAE cellulose column chromatography, the Le^a-decomposing enzyme could be separated from the A-decomposing enzyme. The optimal pH of these enzyme action ranged 6.8-7.2, the optimal temperature 30-37°C and the enzymes were inactivated by heating at 70°C for 5 minutes.
3. The action of these enzymes were inhibited by such metal salts as copper sulfate, mercuric chloride and strontium nitrate. The enzyme action to decompose Le^a substance was inhibited strongly by L-fucose, D-galactose and lactose, and slightly by β-ethyl-N-acetyl-D-glucosaminide and D-glucosamine. The results of the inhibition of enzyme action by sugars indicate that the structure of L-fucose and β-linked D-galactose combined with β-D-N-acetylglucosamine is important as antigenic determinant of Le^a specificity. The action of A-decomposing enzyme was inhibited strongly by N-acetyl-D-galactosamine and slightly by D-galactosamine.

It has been believed among lay people that konjac (Amorphophallus konjac) eating habit is good for health, particularly for hypertensives. Therefore, searching inquiry to the blood pressure levels in konjac raising region is of great interest. Mass physical examination survey was undertaken for the adult population of konjac raising region in Gunma prefecture.
1) 434 subjects, aged 40 and over, were examined, which was the 63.1% of the total inhabitants of the corresponding age groups.
2) Blood pressure levels of male subjects were a little higher than the national norm at 40 to 59 years of age;however, the blood pressures of the age group 60 and over were lower than the national norm, particularly in diastolic.
3) Systolic blood pressure of female subjects was somewhat higher than the national norm, irrespective of ages; diastolic pressure was quite similar with the national norm at any age group.
4) incidence of hypertensives by sub-region tended to be greater in mountainous areas. Rate of respondents for the examination by sub-region showed negative correlation with the incidence of hypertensives, which was significant at 5% level. Judging from the proportion of younger hypertensives discovered, some sub-regions with possible greater risk were pointed out.
In summary, lower level of diastolic blood pressure among the elderly in the region suggests that these people may have lesser risk of cerebral hemorrhage.

Horpital acquired infections caused by multiply resistant staphylocci pressent a big problem that has become increasingly serious. Since the outbreak in Australia the incidence of staphylococcal infections caused by phage type 80 has attracted special attention. And staphylococcal strains type 80/81 are now widely distributed and are isolated frequenrly in the course of routine phage typing of staphylococci in field survey. There are also strains which show the typing patterns 52/52A/80/81, associated whith type 80/81. And the strains which show the typing patterns 81, 80/81, 52/ 52A/80/81 and nontypable are multiply resistant in high frequencies. From these results it is strongly suggested that there exist some relations between phage patterns and drug-resistance of staphylococci.
The tetracycline resistance of staphylococcal strains isolated by this laboratory was transduced by phage 80 which is international phage typing series. The transduction frequency and phage patterns of the recipient strains was discussed.

In the hemagglutination-inhibition tests with sera of various animals, many of lines of Sendai Virus were readily inhibited by guinea pig sera.
This non specific inhibition was found in varying degrees with the lines of virus which had previously been adapted to the mouse. On the othre hand, the lines with successive transfars in eggs were resistant to inhibition by such sera.
Treatment of sera with filtrates of Vibrio cholerae or potassium periodate was successful to remove the inhibitor, but no effective results were obtained by mixing the sera with solutions of trypsin or ordinary heating.
