Semen quality, testicular B-mode and Doppler ultrasound, and serum testosterone concentrations in dogs with established infertility

Retrospective examination of breeding records enabled the identification of 10 dogs of normal fertility and 10 dogs with established infertility of at least 12 months of duration. Comparisons of testicular palpation, semen evaluation, testicular ultrasound examination, Doppler ultrasound measurement of testicular artery blood flow, and measurement of serum testosterone concentration were made between the two groups over weekly examinations performed on three occasions. There were no differences in testicular volume (cm3) between the two groups (fertile right testis = 10.77 ± 1.66; fertile left testis = 12.17 ± 2.22); (infertile right testis = 10.25 ± 3.33; infertile left testis = 11.37 ± 3.30), although the infertile dogs all had subjectively softer testes compared with the fertile dogs. Infertile dogs were either azoospermic or when they ejaculated, they had lower sperm concentration, sperm motility, and percentage of morphologically normal spermatozoa than fertile dogs. Furthermore, infertile dogs had reduced sperm membrane integrity measured via the hypoosmotic swelling test. Infertile dogs had significantly lower basal serum testosterone concentrations (1.40 ± 0.62 ng/mL) than fertile dogs (1.81 ± 0.87 ng/mL; P < 0.05). There were subjective differences in testicular echogenicity in some of the infertile dogs, and important differences in testicular artery blood flow with lower peak systolic and end-diastolic velocities measured in the distal supratesticular artery, marginal testicular artery, and intratesticular artery of infertile dogs (P < 0.05). Notably, resistance index and pulsatility index did not differ between infertile and fertile dogs. These findings report important differences between infertile and fertile dogs which may be detected within an expanded breeding soundness examination

Should splenic autotransplantation be considered after total splenectomy due to trauma?

ABSTRACT Trauma is a public health problem and the most common cause of death in people under the age of 45. In blunt abdominal trauma, the spleen is the most commonly injured organ. Splenectomy remains the most common treatment, especially in high-grade lesions, despite increased nonoperative treatment. Removal of the spleen leads to increased susceptibility to infections due to its role in the immune function. Postsplenectomy sepsis is an important complication and presents a high mortality rate. Patients undergoing splenectomy should be immunized for encapsulated germs, as these are the agents most commonly associated with such infections. Splenic autotransplantation is a simple procedure, which can be an alternative to reduce infection rates consequent to total splenectomy, and reduce costs related to hospitalizations. This review aims to provide evidence-based information on splenic autotransplantation and its impact on the prognosis of patients undergoing total splenectomy. We searched the Cochrane Library, Medline/PubMed, SciELO and Embase, from January 2017 to January 2018 and selected articles in English and Portuguese, dated from 1919 to 2017. We found that the adjusted risk of death in splenectomized patients is greater than that of the general population, and when total splenectomy is performed, splenic autotransplantation is the only method capable of preserving splenic function, avoiding infections, especially postsplenectomy sepsis. Health professionals should be familiar with the consequences of the method chosen to manage the patient suffering from splenic trauma

Eugenol modifies the excitability of rat sciatic nerve and superior cervical ganglion neurons

Eugenol is a phenylpropene obtained from the essential oils of plants such as clove and basil which has ample use in dentistry. Eugenol possesses analgesic effects that may be related to the inhibition of voltage-dependent Na(+) channels and/or to the activation of TRPV1 receptors or both. In the present study, electrophysiological parameters were taken from the compound action potentials of the isolated rat sciatic nerve and from neurons of the superior cervical ganglion (SCG) impaled with sharp microelectrodes under current-clamp conditions. In the isolated rat sciatic nerve, eugenol inhibited the compound action potential in a concentration-dependent manner. Action potentials recorded from SCG neurons were inhibited by eugenol with an IC(50) of 0.31 mM. At high concentrations (2 mM), during brief applications. eugenol caused significant action potential blockade while it did not interfere with the resting membrane potential or the membrane input resistance. Surprisingly, however, at low eugenol concentrations (0.6 mM), during long time applications, a reversible reduction (by about 50%) in the input membrane resistance was observed, suggesting the possible involvement of a secondary delayed effect of eugenol to reduce neuronal excitability.

Leishmania LiHyC protein is immunogenic and induces protection against visceral leishmaniasis

Treatment against visceral leishmaniasis (VL) presents problems by the toxicity of drugs, high cost and/or emergence of resistant strains. The diagnosis is hampered by variable sensitivity and/or specificity of tests. In this context, prophylactic vaccination could represent a control measure against disease. In this study, the protective efficacy of Leishmania LiHyC protein was evaluated in a murine model against Leishmania infantum infection. LiHyC was used as recombinant protein (rLiHyC) associated with saponin (rLiHyC/S) or Poloxamer 407-based polymeric micelles (rLiHyC/M) to immunize mice. Animals received also saline, saponin or empty micelles as controls. The immunogenicity was evaluated before and after the challenge, and results showed that vaccination with rLiHyC/S or rLiHyC/M induced the production of high levels of interferon-gamma (IFN-γ), interleukin (IL)-12 and granulocyte-macrophage colony-stimulating factor in cell culture supernatants, as well as higher IFN-γ expression evaluated by RT-qPCR and involvement from CD4+ and CD8+ T-cell subtypes producing IFN-γ, tumor necrosis factor-α and IL-2. A positive lymphoproliferative response was also found in cell cultures from vaccinated animals, besides high levels of rLiHyC- and parasite-specific nitrite and IgG2a antibodies. Immunological assays correlated with significant reductions in the parasite load in the spleens, livers, bone marrows and draining lymph nodes from vaccinated mice, when compared to values found in the controls. The micellar composition showed slightly better immunological and parasitological data, as compared to rLiHyC/S. Results suggest that rLiHyC associated with adjuvants could be considered for future studies as a vaccine candidate against VL.</p
