Preliminary Analysis of Size Distribution of Objects Suspended in Normal Cerebrospinal Fluid in Case of Venticular Hydrocephalic Enlargement and Internal Hydrocephalus

The paper presents preliminary analysis of normal non-coloured cerebrospinal fluid obtained from patients diagnosed due to suspicion of cerebrospinal fluid malabsorption. According to the findings, the normal cerebrospinal fluid was classified into two groups: A - with clinical diagnosis of ventricular hydrocephalic enlargement and B - with clinical diagnosis of internal hydrocephalus. The analysis of microscopic pictures of normal cerebrospinal fluid in both groups according to numbers and sizes of suspended objects was performed with the aid of Eclipse 600 microscope (with magnification of 1200×) working with a computer by a digital video camera. The authors observed that there is a significant difference in a shape of the distribution curve of objects' diameters between groups A and B. The maximum number of objects in group A was recorded within the range from 5 to 10 μm in diameter size whereas in group B the maximum was recorded within the range from 0.5 to 5 μm in diameter size.
