B:Longitudinal section of the hair and hair follicle
A:
Age 18, female, exposed about 1.1 km from the hypocenter, [#24160,NP159(K)]
B:
In the areas of epilation, the hair matrix including the dermal hair papilla that are the mother cells of the hair, and the connecting inner and outer root sheaths are severely affected.
C: Period of appearance of epilation and hemorrhage (deaths : total)
Although some survivors suffered epilation as early as one
week after the bombing, the majority of cases occurred in
the third week thereafter. The epilation was often complicated
by subcutaneous hemorrhage. (The hair returned to
normal in most survivors after 12 to 14 weeks.)
D: Frequency of epilation and hemorrhage (by distance from hypocenter)
The frequency of epilation showed a close correlation with
distance from the hypocenter, the number of cases increasing
the closer the survivors were to the hypocenter at the
time of the bombing.
