JOURNAL FREE ACCESSHistochemical studies were carried out on lipid, lipoid, glycogen, nucleic acid, phosphatase, calcium and waste pigment, in order to clarify the chemical property of the autofluorescent fine granules in the infective larvae of Ascaris.
Further more the author studied on the localization of these substances in the larva body.
The results obtained as follows:
1) The autofluorescent granules may be lipogenic pigment (waste pigment), which is approximate to ceroid.
In the intestine cells the same pigment was found. And the increase of autofluorescence of the granules with age of larvae may be caused by the increase of lipogenic pigment and calcium.
2) Lipid, that is, fatty acid and soap (perhaps, oleinic acid and calcium salt), cholesterine ester, phosphatide, glycogen, RNA and acid phosphatase were positive in the autofluorescent granules.
3) Lipid, namely, neutral fat, fatty acid and calcium salt, cholesterine ester, phosphatide, glycogen and DNA were positive in the intestine cells.
4) Lipid and glycogen contained in the autofluorescent granules and intestine cells decreased remarkably after one year. From this result, it is considered that the infective larva in egg-shell consumes lipid and glycogen contained in the autofluorescent granules and intestine cells as nutriment.View full abstractDownload PDF (1951K) -

JOURNAL FREE ACCESSAccording to the consideration that glycoprotein hormones such as TSH, FSH and LH or their transmitters may be revealed by PAS-granules in the β cell of the anterior hypophysis, I monthly observed the changes of the pituitary PAS-positive cells in male matured rats, which had been fed under the condition of room temperature in Osaka (3°C-32°C). And these observations were compared with the changes under the exposure to heat (32°C-34°C) and cold (2°C).
In winter, the cells containing PAS-positive granules presented various degrees of degranulation in the PAS-stained sections and two cases of them were observed like “T-cell”. In summer, the sections showed that PAS-positive cells were atrophic. The results of the exposed cases to heat and cold corresponded with that of monthly observed cases. From the present observation it could not be possible to identify “thyrotrophs”, “FSH gonadotrophs” and “LH gonadotrophs” respectively. But, it was noticed that these changes seemed to be more sensitive in the central zone of the anterior lobe than in the so-called “sex-zone”, and in the exposure to cold PAS-positive cells increased in the central zone.View full abstractDownload PDF (6641K) -

JOURNAL FREE ACCESSIn a rural health center district belonging to Yamanashi Prefecture, where infant mortality has constantly shown a lower level compared to the national average figure, a socio-economical analysis was made on the infant mortality over a period of nearly a decade from 1948 to 1956.
The leading cause of infant deaths in this area during the period mentioned above was the infections which reached as high as 55.9% and were most important from the standpoint of infant care.
Among the socio-economical factors the occupational construction of a community had a keen relationship to infant mortality; the areas which were composed with more proportion of farmers showed higher infant mortalities compared to the other areas having less proportion of farmers.
When analysed topographically, dividing the whole district into three sections, i.e. hilly, flat and medium, the last indicated the highest infant mortality. The reason is most likely due to the fact that the mothers in this section engaged in out-door labour for longer hours and cared after their children for shorter hours in daily life as compared the other two.View full abstractDownload PDF (963K) -

JOURNAL FREE ACCESSAs to the relationship between leprosy and tuberculosis a number of bacteriological, immunological, histological and clinical reports have been published. Epidemiological features in relation between these two diseases in this country will take an important role in connection with those studies and also in establishing an ultimate control measure for the two diseases.
The result showed a keen similarity of epidemiological patterns in the two diseases.
1) The decreases of mortality, incidence and prevalence from the beginning of this centutry up to 1957 show quite similar trends in both leprosy and tuberculosis.
2) The male to female ratio of the two diseases in incidence has been always more than 100 and it has become very similar in tecent years. In age distribution those of the two showed a similar pattern toward the older age groups.
3) In BCG inoculation rate, tuberculin positive rate, incidence by age, and severity of leprosy and tuberculosis indicated a close association. Concerning the family aggregation both the diseases showed an epidemiological likeness, although it was slightly higher in leprosy.
4) Also in geographical distribution the two diseases had a similar figur, higher in southern part of this country. The rate of leprosy patients complicated with tuberculosis by age was very alike the prevalence of tuberculosis by age. Finally leprosy and tuberculosis had a common entity against the effective chemotherapeutic agents.View full abstractDownload PDF (1180K)
