Of the 3,840 smears examined by the microscope using oil immersion
lens, 1,185(30.9%) were positive for malaria, while 2,655(69.1%) cases tested negative.
A, B, and K: water immersion at 63[degrees]C, 100[degrees]C, and 25[degrees]C; C and D: oil immersion
at 100[degrees]C and 150[degrees]C; E, F, and G: air drying at 63[degrees]C, 100[degrees]C, and 150[degrees]C; H and J: infrared drying at 100[degrees]C and 150[degrees]C.
In contrast, no change in morphology, differential counts or average platelet numbers per oil immersion
field was seen on smears prepared on day-1 of venipuncture but stained five days later.
4, b shows the [TS.sub.F] change curves of swollen rubber at different temperatures after 168 h of crude oil immersion
. As the temperature increased, the TSF curve decreased.
The presently isolated Chhidruan specimen is however distinct in having circular corpus, which is more thick and dark brown in color making detection or identification of taenae rather difficult even under oil immersion
The NBR dissolution induced a slight fall, with 18% loss after oil immersion
and 30% decrease after heat aging.
Alternate method is the average number of platelets per oil immersion
field (OIF) multiplied by the patient's haemoglobin concentration in g/dl and then multiplied by 1000 to yield platelet count estimation per microliter.
Internal morphology (sporozoites) was visible in some Cystoisospora cysts under oil immersion
(100x magnification) lens.
Periodic samples were examined under the microscope using an oil immersion
objective lens and the progress of sporulation was recorded.
He also talks of his "disastrous" year in neuropathology and neurochemistry: "I screwed the oil immersion
objective of the microscope through several priceless slides.

There are other advantages over oil immersion
fryers, he added.
