Table schema:
CREATE TABLE table_238124_1 (bleeding_time VARCHAR, partial_thromboplastin_time VARCHAR, prothrombin_time VARCHAR)

Question: What was the bleeding time during the prolonged partial thromboplastin time in which the prothrombin time is unaffected?
SQL: SELECT bleeding_time FROM table_238124_1 WHERE partial_thromboplastin_time = "Prolonged" AND prothrombin_time = "Unaffected"
