In this study, Flow cytometric analysis of Oxazine
750-stained reticulocytes was done with the help of Miles H*3 blood analyser to determine reticulocyte indices.
The large numbers of biologically active molecules that contain the oxazine
nucleus has play important roles in the drug discovery process and exhibit various biological activities [1, 2].
We previously reported the synthesis of some novel disperse dyes based on substituted pyridines and their derivatives, oxazine
, carbooxyanilide and thiocarbamate and evaluated their insecticidal and antifungal activity [18, 19].
The reaction involves the use of a di-functional phenolic derivative and diamine, producing a linear polymer that contains oxazine
rings in its main-chain .

ring-substituted benzoxazines," Polymer Chemistry, vol.
For optical fluorescent method, polymethine and oxazine
fluorescent dyes are used in the PLT-O and PLT-F analysis, respectively.
The increase of the binding energy of N[H.sub.3] with the neutral PMD molecule occurs due to the structure of associate in which the N-H bond of the ammonia molecule closes the six-membered ring with the OCNH group of the oxazine
Spirooxazine dyes open their oxazine
rings upon UV irradiation; the concentration of spirooxazine in its ring-opened form increases.
170 was chosen to calculate the optical gain possibility in polymeric optical fiber structures.
FTIR (KBr): v = 1498 (tri-substituted phenyl group); 1231 (s; [v.sub.as] (C-O-C of benzoxazine ring)), 1016 (s; [v.sub.s] (C-O-C of benzoxazine ring)); 1085 (s; vas (Si-O-C)); 931 (oxazine
According to Wang and Ishida 2000, the polymerization occurred at oxazine
structure via ring opening influence by distortion of its semichair structure above and below benzene ring plane.
