Ultrastructure of the camel monocyte.

The fine structure of the camel monocytes was studied in order to record its constituents because these informations were missed from the literature. The observations revealed the presence of a few short cisternae of rough endoplasmic reticulum and various forms of vesicles associated with the Golgi complex which were seen near the mitochondria. The distribution of the cytoplasmic organelles seemed to be located adjacent to the main indentation in the nuclei. Camel monocytes were found to possess microvilli of varying length and number. The functional morphology of the above mentioned structures was discussed.

Progress in element analysis on a high-voltage electron microscope.

X-Ray microprobe (XMA) and electron energy-loss (EELS) spectrometers have been installed on the high-voltage electron microscope (HVEM). The probe size has been measured and background reduction is in progress for XMA and EELS as are improvements in electron optics for EELS and sensitivity measurements. XMA is currently useful for qualitative analysis and has been used by several investigators from our laboratory and outside laboratories. However, EELS background levels are still too high for meaningful results to be obtained. Standards suitable for biological specimens are being measured, and a library for quantitative analysis is being compiled.

Distinction of benign from malignant ovarian cysts by ultrasound.

The ultrasonic characteristics of benign and malignant cystic ovarian tumours have been reviewed. The value of each of eight different ultrasonic features has been assessed and the specificity of each for confirmation or exclusion of malignancy is indicated. In combination they permit correct differentiation in 91 percent of cases.
