Cytomorphological Pattern Frequency in Tuberculous Lymphadenitis Cytomorphological Pattern Number (%) Epithelioid granuloma with caseous necrosis 6 (%) Epithelioid granuloma without necrosis 5 (%) Necrosis only without granuloma 17 (%) Polymorphs
with necrosis 12 (%) Table 9.
In these methodologies, the [alpha]L x [H.sub.2]O was used as initial reagent and dissolved in a basic methanol solution employed as the reacting media for the conversion of this polymorph
into anhydrous [beta]L.
The energetic ordering (Table 6) of the five KNb[O.sub.3] polymorphs
is identical for all considered functionals and, most importantly, in accordance with the observed experimental sequence.
However, it is important to note that the monoclinic polymorph
is just more refined model structure of type (II) [La.sub.2][O.sub.2]C[O.sub.3] .
Nonetheless, calcium carbonate aragonite polymorph
recently emerges as one of the most popular targets among many scientists for profound exploration in many aspects, especially in the biomedical and pharmaceutical fields [1, 7-10, 20-22].
At 10[degrees]C, the three polymorphs
of CaC[O.sub.3] (aragonite, calcite, and vaterite) coexisted.
The biopsy showed fibrovascular tissue densely infiltrated by lymphocyte s, histiocytes, plasma cells and polymorphs
in a background of focal necrosis.
According to the literature the most conspicuous histological feature in acute ENL is the infiltrate of polymorphs
in the reaction centre.
Few cases (54; 15.38%) with necrosis and granuloma showed AFB negativity whereas 36 (10.25%) smears that showed necrosis and polymorphs
were reported as suppurative lymphadenopathy and 105 (29.62%) cases that did not show necrosis or granuloma and also were negative for AFB were reported as chronic nonspecific lymphadenitis, which is also similar to the study conducted by Gupta et al. AFB were mostly visible in purulent aspirate whether acellular or accompanied by granuloma, and in the absence of ZN staining, case can be misinterpreted as an acute lymphadenitis.
Other metastable polymorphs
such as [delta]-[Al.sub.2][O.sub.3] can be formed when temperature is higher than 800[degrees]C .
of amino acids are ascribed to the complex interactions between the hydrogen bonding moieties (amino and carboxy groups) and side chains, which permit the steric and electrostatic interactions that specifically form the well-ordered aggregates in the solid phase.
On 7th day sections showed mild inflammatory reaction with more polymorphs
and mononuclear cells in the lamina propria and submucosa and hypertrophy of tunica advantitia in group I (Fig.11); whereas in the fresh swim bladder group, there was mild inflammatory reaction with more immature neutrophils in the propria submucosa of the host without any union between the host and the graft.
