Anti-inflammatory effects of Brazilian ginseng (Pfaffia paniculata) on TNBS-induced intestinal inflammation: experimental evidence

Inflammatory bowel disease (IBD) is a chronic, relapsing, idiopathic inflammation of the gastrointestinal tract. Clinical studies suggest that the initiation of IBD is multifactorial, involving genetics, the immune system and environmental factors, such as diet, drugs and stress. Pfaffia paniculata is an adaptogenic medicinal plant used in Brazilian folk medicine as an anti-stress agent. Thus, we hypothesised that the P. paniculata enhances the response of animals subjected to colonic inflammation. Our aim was to investigate the intestinal anti-inflammatory activity of P. paniculata in rats before or after induction of intestinal inflammation using trinitrobenzenesulfonic acid (TNBS). The animals were divided into groups that received the vehicle, prednisolone or P. paniculata extract daily starting 14days before or 7days after TNBS induction. At the end of the procedure, the animals were killed and their colons were assessed for the macroscopic damage score (MDS), extent of the lesion (EL) and weight/length ratio, myeloperoxidase (MPO) activity and glutathione (GSH), cytokines and C-reactive protein (CRP) levels. Histological evaluation and ultrastructural analysis of the colonic samples were performed. Treatment with the 200mg/kg dose on the curative schedule was able to reduce the MDS and the EL. In addition, MPO activity was reduced, GSH levels were maintained, and the levels of pro-inflammatory cytokines and CRP were decreased. In conclusion, the protective effect of P. paniculata was related to reduced oxidative stress and CRP colonic levels, and due to immunomodulatory activity as evidenced by reduced levels of IL-1β, INF-γ, TNF-α and IL-6.

Exploring the virome of diseased horses

Metagenomics was used to characterize viral genomes in clinical specimens of horses with various organ-specific diseases of unknown aetiology. A novel parvovirus as well as a previously described hepacivirus closely related to human hepatitis C virus and equid herpesvirus 2 were identified in the cerebrospinal fluid of horses with neurological signs. Four co-infecting picobirnaviruses, including an unusual genome with fused RNA segments, and a divergent anellovirus were found in the plasma of two febrile horses. A novel cyclovirus genome was characterized from the nasal secretion of another febrile animal. Lastly, a small circular DNA genome with a Rep gene, from a virus we called kirkovirus, was identified in the liver and spleen of a horse with fatal idiopathic hepatopathy. This study expands the number of viruses found in horses, and characterizes their genomes to assist future epidemiological studies of their transmission and potential association with various equine diseases.

Púrpura trombocitopênica idiopática: importância do cirurgião-dentista no diagnóstico

This paper presents a case report of a patient with idiopathic thrombocytopenic purpura (ITP) diagnosed in routine dental care. ITP is defined as a decrease in the number of circulating platelets and generally shows oral manifestations. In this light, we show that the general dental practitioner must be ready to detect ITP signs and symptoms, especially oral changes that are not of dental origin, so as to immediately prescribe the proper treatment. Without this treatment, this pathology may well be irreversible and fatal.
