Treatment of forearm diaphyseal defect by distraction compression bone transport and continued distraction for radial head reduction: A case study.

Treatment of infected forearm nonunion and defects represents a difficult task for the operating surgeons. Conventional methods like composite and vascularized fibular grafts and the induced membranes filled with cancellous autografts or the Masquelet technique have been reported to be useful and successful, but sometimes it is difficult to predict the outcome and cannot address simultaneous deformities or the need to apply gradual distraction for reduction of a chronically dislocated radial head. Ilizarov technique has an answer for such conditions.

[Estimation of the sanitary and microbiological indices of stored and bacteriophaged milk].

The paper gives data on the microbiological study of raw milk delivered by various suppliers to a reprocessor. More than 57.3% of the farms are shown to deliver abnormal milk of poor and very poor sanitary quality.

[Complex form of adaptive behavior in rats].

Two problems have been dealth with: a) are rats able by self-learning to form purposive associations, involving elements of reasoning object activity and b) at what age period are they most capable of purposive tool activity. The experiments were performed on 55 rats aged from two to three, five to six and eight to ten months. It was established that tool activity in rats appeared on the 14th to 34th experimental day in 14.
