Ethological analysis of sexual behavior of rats
In the study of sexual behavior the following parameters are registered in males:
– the number of attempts of mounting on a female,
– the number of mounts,
– the quantity of intromissions,
– the number of ejaculations,
– anogenital grooming (the number of cases),
– sniffing of a female (the number of cases),
– sniffing of female genitals (the number of cases),
– grooming of female body (the number of cases),
– the quantity of copulation series,
– the latent period of the first ejaculation.
The rate of initiation of mating is assessed by latent periods of mount and of intromission.
The increase in the latent period of intromission may be an indicator of an erectile dysfunction. The duration of the intervals between intromissions and the quantity of mounts followed by intromissions indicate the level of excitation.

Elements of sexual behavior of rats: A – sniffing of a female nose; B – sniffing of anogenital area of a partner; C – grooming of a female withers; D – attempt of mounting on a female; E-mount; F – postcopulation autogrooming; G – female lordosis position)
Biochemical tests include:
assessment of activity of total acid phosphatase in blood plasma,
analysis of activity of acid phosphatase and tetrachlorella acid phosphatase in prostate homogenate.
During histological examination of prostate nature and severity of the inflammatory infiltrate, edema, fibrosis are estimated. Also it is possible to assess the histological structure of corpora cavernosa of penis and the level of endothelial nitric oxide expression.

ABSTRACT. Orozin (alpha-1 acid glycoprotein) pharmacological activity was studied on the experimental model of Kidney Ischemia-Reperfusion (K I/R). Actovegin was used as reference product. THE AIM: to evaluate Orozin effects in kidney ischemia-reperfusion (K I/R) experimental model. MATHERIAL AND METHODS: Male Wistar rats were carried out right-handed nephrectomy followed by mechanical clamping of the vascular bundle of the left kidney during 45 minutes and subsequent reperfusion. Drugs administrated intravemous in two steps: 10 minutes before stop mechanical clamping of the left kidney vascular bundle and 30 minutes after reperfusion. Blood chemistry value (creatinine and urea levels) were used as effectiveness criteria. After 2 and 24 hours of reperfusion the tissues of kidney were collected for histological assays. RESULTS: Study of experimental model of acute renal faiure showed cytoprotective effect of Orozin confirmed by biochemical and histological analysis [Full text is available in Russian].

The effects of the repeated intramuscular and intravenous administration of the deamino-Cys-Tyr-Ile-Gln-Asn-Cys-Pro-Arg-Gly-NH2 based therapeutic agent on the generative function of the adult male and female outbred rats are presented in this study. The ability of the experimental animals to fertilize and conceive under the influence of the tested agent was assessed. The effect of the drug on the morphofunctional characteristics of the spermatozoa, as well as pre- and postimplantational mortality, was investigated. Additionally, the physical and zoopsychological development of the offspring of the animals that received the drug during the gametogenesis period was evaluated. The results suggest that the the usage of the deamino-Cys-Tyr-Ile-Gln-Asn-Cys-ProArg-Gly-NH2 based drugs must be restricted when planning for pregnancy [Full text is available in Russian].

Approbation of transrectal electroejaculation technique for rats // Laboratory Animals for Science. – 2019, 3. https://doi.org/10.29296/2618723X-2019-03-07ABSTRACT.The method for rats’ semen collection by transrectal electroejaculation is relevant for researching the effect of tested medicines on sperm quality parameters in the dynamics without euthanasia. In our study the transrectal electroejaculation was tried out using medicines as additional stimulation and without them. Three animal groups were formed (10 animals per group): control group (without additional stimulation); other two animals group were received Viagra® and Oxytocin® as additional stimulation before electroejaculation. The probe with electrode was inserted into rectum of anesthetized animals. The electrode was supplied with a current frequency of 60 Hz and voltage output of 0.97 to 2.00 V. The voltage output was gradually increased in 2V for 2–4 sec until the penis was erect or maximal voltage – 9.47 V. During the voltage output increased it has changed position of the electrode in the animal rectum. The increasing of voltage output was stopped and position of the electrode in the animal rectum was fixed when an erection appeared. Then electroejaculation was continued under these conditionals until animal ejaculated. In results our study ejaculate were collected from all 10 animals in group with the background of Oxytocin® administration and duration time of electroejaculation averaged 5 min per one animal. Duration time of electroejaculation was also 5 min in animals was previously received the Viagra®, but samples of ejaculate were collected from 8 animals in group. In control group samples of ejaculate were collected from 8 animals and duration time of electroejaculation averaged 10 min. Thus it was tested the vital method of rat’s ejaculate collection by transrectal electroejaculation with using medicines as additional stimulation and without them. The greatest efficiency of the technique was achieved by using additional stimulation with Oxytocin®[Full text is available in Russian].
