We present the cytologic features of a case of solid and papillary neoplasm of the pancreas. Cytologically, the tumor was composed of a monotonous population of polygonal cells containing eccentrically located round nuclei with one or two distinct small nucleoli and a finely stippled chromatin pattern. The tumor cells were similar to those of the islet cell tumor and showed isolated loosely aggregated and solid sheets or large cell clumps. The large cell clumps revealed a branching papillary structure containing fibrovascular central core, which is characteristic histologic feature of solid and papillary neoplasm of the pancreas. This case was confirmed by tissue examination including histochemical, immunohistochemical and electron microscopical studies. Ultrastructurally, the tumor cells contained a few membrane-bound electron dense granules.

The major blood supply to the femoral head is probably damaged by the fracture of the femoral neck especially when it is a displaced fracture. Complications such as delayed or nonuion of the fracture and avascular necrosis of the femoral head are common. Revascularization after reduction and internal fixation appears to be a slow process and in many patients late segmental collapse occurs. Various techniques have been proposed to restore the blood supply or to improve the circulation to the femoral head. Hereby we performed internal fixation and an autogenous muscle-bone pedicle graft composed of the quadriceps femoris muscle in 3 cases of old, neglected displaced femoral neck fracture. The results seemed to be good in regard to bony union in all 3 cases but it would be needed further follow up study for developing of any avascular necrosis.

This research was performed to investigate whether or not the psychobiology of posttraumatic stress disorder is related to dopamine systems. Plasma homovanillic acid levels were measured in 16 male patients with posttraumatic stress disorder and in 16 nonpsychiatric normal males. Posttraumatic stress disorder was diagnosed using the DSM-IV. Plasma homovanillic acid levels were significantly higher in patients with posttraumatic stress disorder than in normal control subjects(p<0.05). The findings of this study suggest that hyperactivity of dopamine systems may be related to the psychobiology of posttraumatic stress disorder.

The search for tumor-avid agents for use in nuclear medicine imaging is an ongoing field of importance. The purpose of this study was to determine the affinity for radiolabeled vitamin B12 by a wide histologic variety of tumor types in mice. Seventeen different types of tumor were grown subcutaneously in female Balb/C or Balb nu/nu(nude) mice. When the tumors reached about 1 cm in diameter, mice were injected intraperitoneally with 57Co-vitamin B12. Twenty-foul hours later, the mice were sacrificed. Organs and tissues were removed, weighed, and activity per mg determined by gamma counter. Values represented cpm/mg tissue that was normalized to 20 grams body weight for each mouse. A wide variety of tumor types showed significant uptake and concentration of 57Co-vitamin B12, as evidenced by tumor:tissue activity ratios. For many tissues of great importance in terms of background(bone, muscle, blood), the tumor:tissue activity ratios of uptake were high. These data strongly suggest that further efforts to evaluate the utility of radiolabeled adducts of vitamin B12 for clinical use in oncologic imaging are warranted.
