Today, in image analysis the broadest possible rationalization and economization have become desirable. Basically, there are two approaches for image analysis: The image analysis through the so-called scanning methods which are usually performed without the human eye and the systems of optical semiautomatic analysis completely relying on the human eye.The new MOP AM 01 opto-manual system (fig.) represents one of the very promising approaches in this field. The instrument consists of an electronic counting and storing unit, which incorporates a microprocessor and a keyboard for choice of measuring parameters, well designed for easy use.Using the MOP AM 01 there are three possibilities of image analysis:the manual point counting,the opto-manual point counting andthe measurement of absolute areas and/or length (size distribution analysis included).To determine a point density for the calculation of the corresponding volume density the intercepts lying within the structure are scanned with the light pen.

ABSTRACT The effect of reserpine on the secretion of FSH and LH was studied as well as the role of the peripheral effect of reserpine after hypophysectomy. The results in the unoperated animals suggest that reserpine inhibits the pituitary secretion of both FSH and LH. Both these hormones combined with reserpine had a very different biological effect than was seen without reserpine. HCG (LH-like) and particularly PMS (FSH-like) hormones combined with reserpine caused definite enlargement of the ovaries. In the hypophysectomized groups, the effect of the PMS and HCG hormones administered together with reserpine or without it was the same with regard to the weight of the ovaries, but not with regard to their histological picture. On the basis of these results, reserpine may be said to have a peripheral effect although the nature of its mechanism of action is difficult to state. Reserpine probably affects the ovaries by inhibiting the follicular cycle and, consequently, the formation of new and more mature follicles.
