[Additional phragmoplast corrects abnormal cytokinesis in wheat x rye hybrid pollen mother cells].

The phragmoplast dysfunction in wheat x rye hybrid F1 male meiosis has been described. The pollen mother cells (PMCs) show the phenotype where transition from central spindle fibers (forming a solid bundle) to a phragmoplast (hollow cylinder) is blocked. The blockade suppresses centrifugal movement of the phragmoplast and cell plate formation.

Body composition and physiological characteristics of law enforcement officers.

The physical work capacity, body composition, and physiological characteristics of 12 law enforcement officers (9 males, 3 females) were measured. Subjects included a representative sample from the occupational categories of detective, staff, investigative and patrol officer. Mean maximal oxygen uptake of the men was 42.

The relative roles of neurological examination, functional abilities, and computed tomography in the definition of treatment failure in patients with anaplastic gliomas.

Forty-one patients with anaplastic gliomas undergoing postoperative treatment and evaluation underwent bimonthly evaluation of the following indices of treatment failure: neurological examination; Karnofsky functional rating; and computed tomography (CT) brain scanning. Treatment failure was declared when neurological examination or Karnofsky rating showed increased impairment or when CT scan revealed an increase in tumor sizes. Most often, all three indices simultaneously indicated treatment failure.

Immunobiology of primary intracranial tumors. Part 7: Active immunization of patients with anaplastic human glioma cells: a pilot study.

Twenty patients with malignant gliomas were selected for active immunization within 4 weeks following surgery. Each patient had a Karnofsky Functional Rating equal to or greater than 70, a peripheral blood lymphocyte count equal to or greater than 1000 cells/cu mm, skin test responses to one or more of four recall antigens, peripheral blood T-cells equal to or greater than half that of control, and was not receiving steroid therapy at the time of entry into the study. Each patient received subcutaneous inoculations with one of two human glioma tissue culture cell lines (D-54MG or U-251MG) monthly, with 500 micrograms of bacillus Calmette-Guérin cell wall (BCG-CW) being included with the first inoculation.

The role of anticonvulsant medications in the management of patients with anaplastic gliomas.

All 100 patients in a protocol of therapy for anaplastic gliomas were studied with regard to occurrence of seizures preoperatively and postoperatively. Patients without a history of seizures preoperatively had a similar incidence of seizures postoperatively, whether anticonvulsant medications were prescribed prophylactically or not.
