Serum concentration of 25 (OH) vitamin D in healthy dogs: factors as age, sex, and diet DA FONSECA, FLÁVIA M.; BELTRAME, OLAIR C.; SEIXAS, SANDRA V.; LASKOSKI, LUCIANE M.; FÉLIX, ANANDA P.; Rosangela Locatelli Dittrich COMPARATIVE CLINICAL PATHOLOGY (PRINT), v. 29, n. 3, p. 697-703, 2020 DOI Palavra-chave: dogs; Vitamina D Áreas do conhecimento: Ciências Biológicas; Medicina Veterinária resumo ... The main source of vitamin D in dogs is their diet. Information on vitamin D in dogs and on factors that may influence the serum concentration of 25(OH)D are still scarce. This study aimed at determining serum 25(OH)D values in healthy dogs and evaluating its association with factors such as sex, age, and diet. Blood samples were collected from healthy intact male and female dogs divided into two groups: (G1) 30 dogs (Beagles), 15 adults and 15 puppies, receiving standardized diet; (G2) 29 dogs of different breeds, adults, receiving varied diets. The 25(OH)D was analyzed by the chemiluminescence method. Serum levels of 25(OH)D are not associated with sex, but the concentration is lower in puppies (30.6 ng/mL) than in adults (34.9 ng/mL) (G1), P < 0.05. There was no difference between the types of diet: commercial food (40.6 ng/mL), and the combination of commercial and homemade food (36.0 ng/mL), P = 0.2. The concentration of 25(OH)D may not be directly associated with vitamin D intake (G1), P = 0.08, which emphasizes the importance of considering and investigating multiple variables that may influence the availability of vitamin D in their circulation.

Spinal cannabinoid CB1 or CB2 receptors activation attenuates mechanical allodynia in streptozotocin-induced diabetic rats Maryna Rodrigues GONÇALVES; Milena Santana da CONCEIÇÃO; JESUS, CARLOS HENRIQUE ALVES; Alexia Thamara Gasparin; Evelize Stacoviaki Rosa; Cunha, Joice M.

Thus, new therapeutic targets need to be urgently investigated. Studies have shown that cannabinoids have promising effects in the treatment of several pathological conditions, including chronic pain. Thus, we aimed to investigate the acute effect of the intrathecal injection of CB1 or CB2 cannabinoid receptor agonists N-(2-chloroethyl)-5Z, 8Z, 11Z, 14Z-eicosatetraenamide (ACEA) or JWH 133, respectively (10, 30 or 100 μg/rat) on the mechanical allodynia associated with experimental diabetes induced by streptozotocin (60 mg/kg; intraperitoneal) in rats. Cannabinoid receptor antagonists CB1 AM251 or CB2 AM630 (1 mg/kg) were given before treatment with respective agonists to confirm the involvement of cannabinoid CB1 or CB2 receptors. Rats with diabetes exhibited a significant reduction on the paw mechanical threshold 2 weeks after diabetes induction, having the maximum effect observed 4 weeks after the streptozotocin injection. This mechanical allodynia was significantly improved by intrathecal treatment with ACEA or JWH 133 (only at the higher dose of 100 μg). Pre-treatment with AM251 or AM630 significantly reverted the anti-allodynic effect of the ACEA or JWH 133, respectively. Considering the clinical challenge that the treatment of DPN represents, this study showed for the first time, that the intrathecal cannabinoid receptors agonists may represent an alternative for the treatment of DNP....
