Abstract To properly assess men and women with sexual dysfunction, evaluators should take a biopsychosocial approach that may require consultation with multiple health care professionals from various fields in order to get to the root of the sexual dysfunction; this multidisciplinary methodology offers the best chance of successful treatment. For males, this article focuses on erectile dysfunction (ED) and hypogonadism. The initial evaluation of ED involves a thorough case history, preferably taken from the patient and partner, physical examination, and proper laboratory and diagnostic tests, including an acknowledgment of the subjective complaint. The diagnosis is established on the basis of an individual's report of the consistent inability to attain and maintain an erection sufficient to permit satisfactory sexual intercourse. Initial workups for ED should entail a detailed history that can be obtained from a validated questionnaire such as the International Index of Erectile Function and the Sexual Health Inventory for Men. Hypogonadism is evaluated using the validated Androgen Deficiency in the Aging Male questionnaire and laboratory testing for testosterone deficiency. Treatments logically can begin with the least invasive and then progress to more invasive strategies after appropriate counseling. The last and most important treatment component when caring for men with sexual dysfunction—and, arguably, the least practiced—is close follow-up.

Aquaculture Production

Aquaculture production is a promising direction for the development of food production. Like traditional types of animal husbandry, it needs effective medicines for veterinary use, which would ensure not only the well-being of farmed aquatic organisms, but also increase the safety of the fish products and non-fish objects of fishing. The development of measures to control epizootic processes in aquatic organisms is impossible without the creation of new immunological preparations. The development and use of immunobiological drugs will reduce the use of antimicrobial agents. The corresponding set of pharmaceutical drugs was transferred from the traditional veterinary medicine, but due to the peculiarities of the biology of aquatic animals, their immunity and the characteristics of specific pathogens, this could not be done with biological products. The short development time in the aquaculture industry poses current challenges in the form of a lack of basic and applied research for relatively poorly understood groups of new pathogens. The immunological processes associated with the development and intensity of the immune response in aquatic organisms require a detailed study. For domestic aquaculture producers, the analysis and dissemination of the experience accumulated by mankind and the application of advanced developments in this area are even more relevant, since Russia is just beginning its path of intensifying aquaculture production. At the same time, it is clear that the prohibition of the use and monitoring of antimicrobial agents in food products and feed requires a change in the approach to the problem and will lead to the creation of new immunobiological drugs. The market for immunobiological preparations for aquaculture is the most promising for development. In the article, the authors provide data on the development and registration of vaccines for aquaculture in Europe, North and South America.

ABSTRACT This report is a summary of 10 years of experience with the complement fixation test as adopted for the immunoassay of HCG in serum. It is based on published as well as unpublished material. The discussion centers mainly around methodological problems, criteria of reliability, and clinical observations. It is our impression that the complement fixation test is a reasonably rapid and simple technical procedure. It is standard practice in every bacteriological and virological laboratory. The precision of the HCG assay is high. Its accuracy is good. The complement fixation assay, as reported here, fulfils the criteria of specificity. It has been evaluated by means of serological techniques and through comparison between biopotency and immunopotency of HCG in serum with reference to a common standard. Its application for routine as well as research work is illustrated.
