Abstract :We made histological observation on the arteria uterina media of 20 goats in Okinawa, paying special attention to the relationship between the changes of tunica intima and the history of parturition. 1. The degree of the changes of the right and left side tunica intima arteria uterina media in the same indevidual parallels except in a few cases. 2. Comparing the observation of swelling of the tunica intima, and the breaking and splitting of the lamina elastica interna with respect to each age group, we found great changes in the individuals of higher age groups such as full 4 years, though the extent of changes from O year to 3 years is no remarkable. 3. Comparing the degree of above-stated changes with the history of parturition, as multipara than nullipara and still more the increase of parturiton frequency, the change is in inclined to gradually high. 4. According to the histological observation of the tunica intima we classified the arteria uterina media of goats into 4 groups. 5. There is only I type of the arteria uterina media for nullipara, which shows the structure of normal muscle arteria. most of II and III type with 1 parturition show slight or medium chages and in 2 parturitions most of IV type show. 6. We found several examples of the same observations of Takahata's sclerotic gestation rings or Miyagi's sclerotic gestation layer in arteria uterina media of goats and conformed lamellar structures of the higher 5 lamelas in 1 example of 6 parturition in 8 years. 7. Above many examples such as arteria uterina media of goats relate with the history of parturition more deeply than the age. though these are not so remakable as swines and cows, we imagine that repeated pregnancy and sudden changes of blood by parturition induce the above mentioned.
