The author has observed both BCG inoculated and non-inoculated group with regard to the results of OT test and X-ray examination conducted upon them.
The summary of the observation is as follows:
1. B.C.G. non-inoculated group
a) In the group less than 10mm of erythema, fairIy low morbidity rate was noted on X-ray examination, while both morbidity and severity rates increased in proportion by the size of erythema.
b) Correlating the intensity of tuberculin reaction with the mobility rale assuming that suggestive active tuberculosis on x-ray the lowest rate was seen in the erythema group, the highest in the necrosis and bleb groups, and inculturation and double erythema groups fell on the intermediate Ievel.
c) Sex is found to be no factor in establishing the relationship.
d) By age, the positive findings could be seen in the group under 10 mm erythema among 16 years old
and under. The rate of increase of the positive fìndings by size of erythema under 16 year of age group was found iow in comparison with that of 17 year of age and over group, the Itter group showing high increase. However, no positive findings with under 10mm erythema were noted in the latter group. As to the intensity of the reaction, the morbidity rates were seen almost evenly distributed among the necrosis, bleb and other groups in under 13 years of age, Over 14 years of age, it was found that morbidity rates were apparently high in the necrosis and bleb groups.
2)B.C.G. inoculated group.
a) Unlike the B.C.G. non-inoculated group, no relationship could be observed between the size of erythema and the morbidity rate. In general, the highest morbidity rate was seen in the group of 11 to 24 mm of erythema size.
b) As to the intensity of tuberculin reaction vs. the morbidity rats, the highest rate appeared in the erythema group. In other groups than the necrosis group, the rates of positive findings were seen approximately equal, although the bleb group showed the lowest among the other groups in intensity, the fact apparently differing from the non-inoculated group.
c) The higher rate of the positive findings was noted in female, except in the erythema group exceeding 65 mm in size. As to the intensity, female showed the higher rate than male except the necrosis group.
d) When the relationship between the tuberculin redies and the morbidity rate under X-ray examination was viewed from the number of the B.C.G. inoculated, the followings were found: In the single B.C.G. inoculated group, all the positive findings were distributed in the erythema group showing less than 45 mm in size. As to the intensity of the reaction, the highest morbidity rate was seen in the erythema group. In the double inoculated group, the highest morbidity rate was noted in the erythema group, showing over 65 mm in size. However, the positive finding were predominantly distributed in the erythema group under 25 mm in size. As to the intensity of the reaction, the highest rate was seen in the necrosis group. In the triple inoculated group, the majority of the positive findings was seen distributed in the erythema group under 15 mm in size. The morbidity rate were almost equal among the different intensity groups except the necrosis.
e) Age seems to be of no factor in establishing the relationship between the tuberculin reaction and the morbidity rate, when considered from the erythema size as well as the intensity of the reaction, except for that the age group of 6 to 13 year with necrosis showed higher morbidity rate than the other age groups. However, it is noted that in higher age brackets the morbidity rate tends to increase in general. |
