Q: Abstract: Surgical management of major venous injuries remains controversial. The medical records of 184 patients with major venous injury were reviewed. Forty-three patients had isolated venous injury; 31 of 43 patients (72%) underwent ligation to treat their vein injury. Another 141 patients had combined arterial and venous injury; 117 of these patients (83%) had ligation. Injured were the inferior vena cava, iliac, femoral, popliteal, distal leg, and arm veins; all patients underwent surgical exploration. Arterial injuries were repaired by standard techniques and venous injuries were either ligated or repaired by end-to-end or lateral phleborrhaphy. Adjunctive fasciotomy was used when clinically indicated. The patients were followed up for 1 month to 9 years. No permanent sequelae of venous ligation were identified. Transient extremity edema developed in up to 32% of patients, regardless of whether vein ligation or repair was performed. This edema resolved completely within 12 weeks of the injury. No extremity was lost after ligation of a venous injury. Although it may be ideal to repair all venous vascular injuries, selective management reflecting mechanism of injury, blood loss, anesthesia requirements, associated organ injury, and other concerns may mitigate against extensive venous repair.

Q: Abstract: Cyst formation can occur in any location where lacrimal gland tissue is present. A new classification is proposed based on these locations: palpebral lobe cysts (simple dacryops); orbital lobe cysts; cysts of the accessory lacrimal glands of Krause and Wolfring; and cysts of ectopic (choristomatous) lacrimal glands. The characteristic clinical presentation, histopathology, and treatment of these lacrimal ductal cysts is described.
Which is the apt title for the abstract? option1: Lacrimal ductal cysts. option2: The treatment of a symptomatic vertebral hemangioma by radiotherapy. A case report.

A: Lacrimal ductal cysts.

Q: Abstract: The NK-1.1(-) mouse was constructed by weekly injections of monoclonal anti-NK-1.1 antibody from birth through adulthood. Spleen cells from these mice have decreased NK-1.1+ cells and null (Thy-1- and B220-) cells. Their splenic NK activity to YAC targets was low and was not enhanced by IFN-alpha or IFN-beta. Bone marrow (BM) of these NK-1.1(-) mice have normal precursors to NK cells: 1) NK activity could be generated from NK-1.1(-) BM cells cultured in rIL 2 for 5 to 6 days. These cultured BM cells expressed Qa-5, Thy-1, AsGm-1, and NK-1.1 antigens. The precursor cells of these BM cytotoxic cells are NK-1.1-; 2) transfer of BM cells from the NK-1.1(-) mice reconstituted the NK activity of irradiated, NK-depleted recipients. Lymphokine-activated killer cells could also be generated from spleens of these NK-1.1(-) mice. Therefore, the NK-1.1(-) mice were specifically depleted of mature cytotoxic NK cells, but not the NK-1.1- precursors of NK cells. This mouse model is valuable to study ontogeny and physiologic relevance of NK cells.
Which is the apt title for the abstract? option1: The NK-1.1(-) mouse: a model to study differentiation of murine NK cells. option2: Laboratory fraud: another damned by publications [news]

A:
