to germinate into
spherules at 37[degrees]C and for optional growth of Histoplasma capsulatum yeast [15, 16].
Moreover, industrial
spherules may contaminate the natural glasses, both at the outcrop and during laboratory treatments [3-5].
Since in all the above-mentioned mires silicate
spherules were detected only in one layer, we proposed a new precise correlation method for Holocene sequences, based on these microimpactites.
Chemical analyses of the South African sediments show that, on average, the layers that contain the
spherules have more than 10 times the concentration of iridium that's normally found in Earth's crust, as well as elevated concentrations of certain chromium isotopes.
(1,38) Both are caused by fungi that grow as spore producing hyphae at environmental temperatures, but as yeasts (
spherules or ellipses) at body temperature within the lungs.
The most common form of C immitis seen in biological specimens is variably sized (20-200 pm), thick-walled mature
spherules containing numerous endospores ranging from 2 to 5 [micro]m (Figure 16).

Histopathology examination revealed that the abscess was pyogranulomatous, with visible fungal
spherules morphologically consistent with Coccidioides spp.
The pathology report also confirmed to be positive for Coccidioides
spherules (Figures 1 and 2).
The agents used for this purpose are as follows: sclerosing agents (Fibrin glue, Tetrasycline, Hidrocloric acide, Microporous Polysaccharide
spherules, Iodized talc), anti-inflammatory drugs (Acetyl salicylic acid, Nonsteroidal anti-inflammatory drugs), chemotherapeutic agents (Fluorouracil, Mytomycin-C) and radiotherapy.
