Use a soft toodibrush and consult a dentist regarding routine oral hygiene, including die use of dental floss. Use an electric razor when possible to avoid small skin cuts. 

Thrombocytopenia is characterized by a decrease in the platelet count (<100,000/mm3). The nurse monitors patients with thrombocytopenia for bleeding tendencies and takes precautions to prevent bleeding. Injections are avoided but, if necessary, the nurse applies pressure to the injection site for 3 to 5 minutes to prevent bleeding into the tissue and the formation of a hematoma The nurse informs the patient to avoid the use of electric razors, nail trimmers, dental floss, firm...

The floss silk from Chorisia speciosa furnished a polysaccharide with a main chain of (1 -> 4) linked P-Xylp substituted at 0-2 by 5 % of uronic acid. The xylan structure also was interposed with a-Rhap units in small amounts. The defatted seeds furnished on aqueous extraction a major fraction, ((9-acetyl, 10 % and protein, 45 %) wich was hydrolysed and analysed by p.c. and GLC, showing Rha (20 %), Ara (16 %), Gal (64 %) and also uronic acids (45 %). Partial hydrolysis gave rise to a polysaccharide free of arabinose, with 46 % of uronic acids. Methylation analysis (GLC -MS) indicated a chain of (1 4) - linked Gal/ (42 % of 2,3,6-Me3-Gal). 

This paper reports the structural features of the silk floss polysaccharide and the partial structure of a viscous acidic polymer obtained from the seeds of Chorisia speciosa. It was of interest to analyze these polysaccarides due to the relationship of Bombacaceae to Sterculiaceae, as well as for its possible commercial uses. 

Polysaccharide isolation. The silk floss (36 g) was cut and extracted with 2 1 benzene-EtOH in a Soxhlet apparatus for 16 h. The residue was extracted with 2 M... 

In terms of the average fi om 20 mature fiiiits, floss silk, seeds and fruit coat were isolated, the ratio being 14 %, 15 % and 71 % respectively. The filaments of floss silk on submission to microscopy, showed mainly unicellular trichomas, some of them being formed by two cells. The presence of lignin in the filaments was suggested by the characteristic reaction with phloroglucinol hydrochloride. 

The silk floss was defatted and hydrolyzed by Saeman s method [10] giving rise to xylose (73 %) and glucose (27 %), Aus indicating the presence of xylan. When the time of hydrolysis was up to 24 h, the presence of rhamnose (5 %) was also evident. However, degradation of xylose was observed after 8 h at 100 °C. 

The xylan from the silk floss (PI) was homogeneous on gel-column chromatography over Sephacryl S-300, having a molecular mass of 52000.
