The effect of exploitation and adrenergic system drugs on sexual reflexes and properties of the semen in somatically mature Polish Large White boars has been presented. At the first stage 8 males were exploited twice a week. Then, previous to semen collection, the animals were given beta-adrenolytic (Propranolol--Polfa), after 30 minutes followed by the preparation Levonor--Polfa (alpha-adrenomimetic). 15 minutes after last injection the semen was collected, this procedure having been repeated twice a week. At the second stage of the experiment the same males were exploited once a week. Like in the first stage, the animals were given the same doses of the drugs in the same sequence. 15 minutes after last injection the semen was collected once a week. At the third stage of the experiment the boars were exploited every day. Again, like in the previous stages, the animals were given the above mentioned beta-adrenolytic and alpha-adrenomimetic to collect the semen 15 minutes after last injection. In all the stages of the experiment 6-8 ejaculates were collected from each boar. Apart from preliminary assessment of concentration and morphology of spermatozoons there was determined the level of protein and activity of selected enzymes in the semen. The sexual drive as well as the time of searching reflex and ejaculation were observed. The drugs applied have been proved to be able to prolong the time of ejaculation reflex. Simultaneous application of beta-adrenolytic and alpha-adrenomimetic to animals exploited twice a week appeared to increase the number of spermatozoons in the whole ejaculate, the percentage of spermatozoons with proper movement and the activity of GGT and fucosidase. Intensive exploitation of a boar with parallel application of the preparations described bring about a gradual decrease in spermatozoons and protein in the ejaculate as well as in the activity of hyaluronidase in its plasma and in conversion to mg protein of semen plasma.

Monoclonal antibodies, 17B1 and 17Q2, which are specific for large molecular weight mucous glycoproteins of airway epithelium, have been used to develop an ELISA method to quantitate the tracheal mucins of humans and rhesus monkeys. The assay is a double-sandwich system that does not depend on either the binding of mucous antigens to the microtiter plate or the use of a second antibody. The assay protocol includes (1) coating the microtiter well with purified IgG of 17B1 or 17Q2, (2) incubating the wells with mucous samples, (3) binding of alkaline phosphatase-conjugated IgG to the wells, and (4) developing the color with phosphate substrate. This ELISA method is very sensitive for human and rhesus monkey tracheal mucins. Quantitation is not affected by the presence of various proteoglycans (keratan sulfate, hyaluronate, heparin, heparan sulfate, and chondroitin sulfate). However, the quantitation is affected by the treatment of antigen with periodic acid and endo-beta-galactosidase. Other enzymes (e.g., neuraminidase, hyaluronidase, chondroitinase, heparitinase, heparinase, fucosidase, keratanase) have no effect on the antigenicity of substrate. The quantitation is linear, with a concentration from 0.2 to 4 ng protein/sample. The ELISA method developed in this study should be useful for quantitating the mucin content of various biologic fluids, such as sputum, bronchoalveolar lavage, and media from cultures following various pharmacologic and physiologic manipulations.
