Total protein concentration in selectively collected secretions from the middle and inferior meatus of the nose.

To clarify the characteristics of nasal secretions, a method for collecting human nasal secretion was devised. Total protein concentration in selectively collected secretions from the nasal cavity was determined using biochemical techniques. Dry absorbent cotton was inserted in each middle and inferior meatus of the nasal cavity for 30 min, and put in a test tube with a plastic sieve for centrifugation. After centrifugation at 5,000 rpm for 20 min, 10 microliters were obtained to measure the protein concentration the nasal secretions was made using spectrophotometry. The amount of nasal secretion samples collected was 50 to 400 microliters per site. Nasal secretions collected from the right middle and inferior meatus contained 80 to 2,450 mg/dl and 260 to 3,270 mg/dl of protein, respectively, while those from the left middle and inferior meatus contained 80 to 2,200 mg/dl and 175 to 3,050 mg/dl, respectively. It was concluded that this new method was clinically useful for collecting nasal secretions, and it permitted selective collection from predetermined sites in the nasal cavity. The total protein concentration level of nasal secretions collected by this method was higher in the inferior meatus than in the middle meatus of the nose, with statistical significance.

A technique of dynamic reduction for displaced fractures of the thalamus of the calcaneum.

A new technique of reduction based on the anatomical structure of the calcaneum was first described in 1974. Two pins were inserted, one into the posterior surface and the other into the plantar surface of the bone. This allowed early mobilisation of the foot. The method can be used in all types of fractures including comminuted fractures of the tuberosity, the tongue type, the central depression type, the severe tongue type, the severe depression type and unclassified severe crush fractures. Complete anatomical reduction was obtained in 58 out of 72 fractures (77%) and 56 out of 64 patients (87.5%) were classified as "very good" by the Maxfield assessment. In this paper the authors discuss their method of management of displaced fractures of the thalamic part of the calcaneum.
