Поведение водорода при кристаллизации и охлаждении железа

С позиций теории направленной химической связи показано, что растворимость водорода в жидком железе и его аллотропических формах α–, γ– и δ–Fe коррелирует с изменением параметра Δе (положительная величина Δе соответствует донорному характеру связи, отрицательная – акцепторному)

Adult Intussusception Caused by an Inverted Meckel Diverticulum

Adult intussusception caused by an inverted Meckel diverticulum is rare. We report a 55-year-old Japanese man with intussusception. He was admitted to our hospital with vomiting and abdominal pain. The abdomen was hard with tenderness and muscle guarding. Computed tomography scanning demonstrated a typical inhomogeneous target-shaped mass in the right abdomen. We diagnosed intussusception and performed emergency surgery. At laparotomy, ileocolic intussusception was observed and the ileocecal segment was resected. The surgical specimen comprised an 84 cm segment of resected ileocecum with an elongated polypoid lesion measuring 11 × 2 cm within the ileal lumen. Histopathological examination demonstrated that the polypoid lesion was an inverted Meckel diverticulum. Postoperatively, the patient made an uneventful recovery
