[FT-207 maintenance therapy of malignant gynecologic cancer].

Maintenance treatment with FT-207 was applied to 92 patients with uterine cancers after initial treatments were performed. Daily dosage of FT-207 was either 600 or 800 mg and the drug was administered orally. The duration of 6 months and the total dosage of 100 g were proposed as administration schedule and 34 patients (37%) received this regimen. Side effects during the treatment were observed in 35 cases (38%). Gastrointestinal disturbance was most frequently observed and other side effects included myelosuppression, general fatigue, hepatic dysfunction and skin toxicities. There were no serious side effects, the treatment was continued in most patients and was interrupted only in 7 cases (8%). In the cases of recurrence or advanced cancer, however, the side effect was the predominant cause for interruption of administration. As for the antitumor effect of the treatment, a survival rate of the patients with cervical cancer of early stages was evaluated. Three-year survival rate in the treatment group was higher comparing to the one reported hitherto.

Establishment of an enzyme-linked immunosorbent assay with a coated deflagellated Salmonella enteritidis antigen for detection of a specific chicken antibody.

We attempted to establish an enzyme-linked immunosorbent assay (ELISA) for field monitoring/profiling purposes for Salmonella enteritidis (SE) infection of poultry flocks. Serotyping rabbit sera, commercially obtained, specific for Salmonella identification sera to O2, O4, O7, O8, S. Vi, S. Hm, and O9, showed negative ELISA (E)-values (< 0.2) on ELISA, except the O9 identification serum (E-value > 0.5). Similar negative E-value results were obtained for antisera to Echerichia coli (E. O antigen). Field serum samples originating from SE-isolated flocks yielded similar positive ratios on both ELISAs including the present coated deflagellated SE antigen and a commercially obtained flagellated SE antigen and that of rapid plate aggregation with a pullorum antigen (PD-RPA). About 100 days after the first monitoring, no SE isolation in the same flock was observed resulting in a carrier state of SE infection. Although both the monitoring results with commercially obtained ELISA and PD-RPA showed lower positive or negative ratios, the present ELISA showed a higher positive ratio than that of the first monitoring. The present ELISA is suggested to be a suitable method to do accurate profiling on the carrier state of infection.

A case study on Salmonella enteritidis (SE) origin at three egg-laying farms and its control with an S. enteritidis bacterin.

In the early 1990s, three egg-laying farms (farms S, T, and B) were thought to have the possibility of Salmonella enteritidis (SE) contamination because positive liquid egg samples originated from those farms. The present study was therefore conducted. The first clarification for SE contamination was the study on the origin of SE contamination including its vertical transmission. The results of SE contamination profiling with dust and manure, food materials, dead embryos, and residual yolks on hatch day in regular monitoring over a few years were clearly negative. Therefore, we concluded the SE transmission/infection was attributed to horizontal infection in the egg-laying farms but not vertical transmission from parental stock, hatcheries, growth, or food materials during a 7-yr experimental period. Second, we attempted to clarify if administration of an SE bacterin (Layermune SE) to growth flocks for the egg-laying farms could reduce SE incidence in liquid egg samples from each egg-laying farm. In the first experiment, we compared SE incidence in liquid egg samples from vaccinated and nonvaccinated flocks (similar age flocks). SE incidence from vaccinated and nonvaccinated flocks showed negative and <2 most probable number (MPN)/100 ml for farm B, <2 and >1600 MPN/100 ml for farm S, and negative and >1600 MPN/100 ml for farm T, respectively. In the second experiment, we compared the SE isolation incidence in the liquid egg samples from nonvaccinated and newly replaced vaccinated flocks in the same chicken houses from each of the three egg-laying farms. SE incidence in the liquid egg samples was similar to that in the first experiment. Therefore, the SE bacterin may play an important role in reducing the SE incidence of liquid egg samples.
