Thymus lymphocyte subsets in uraemic rats were studied using monoclonal antibodies. Severe and moderate uraemia was induced in rats, and sham-operated and normal rats were used as the controls. As a result, the weight of the thymus decreased in uraemic rats. As for lymphocyte subsets, the frequency of W3/25+OX8+ decreased and those of W3/25-OX8-, W3/25+OX8- and W3/25- OX8+ relatively increased in uraemic rats. All these changes were more significant in severely uraemic than in moderately uraemic rats. When thymosin fraction 5 (TF5) was administered to severely uraemic rats, the weight of the thymus increased and the lymphocytes subsets normalized. These results suggest that uraemia may cause a maturational impairment of thymus lymphocytes by the depression of thymic hormone secretion.

Vascular calcification is considered to be a killer of the cardiovascular system, involved inflammation and immunity. There is no approved therapeutic strategy for the prevention of vascular calcification. Sinomenine exhibited anti-inflammatory and immunosuppressive effects.

Rationale & Objective: Peritoneal dialysis (PD) solutions provide both clearance of uremic toxins and sodium and water. An intraperitoneal (IP) solution of icodextrin and glucose designed without the requirement for uremic toxin clearance could provide substantially greater sodium and water removal than PD solutions.
Study Design: We examined varying concentrations of icodextrin and dextrose IP solutions in rats.

Increasing evidence suggests that dysbiosis of gut microbiota exacerbates chronic kidney disease (CKD) progression. Curcumin (CUR) has been reported to alleviate renal fibrosis in animal models of CKD. However, the relationship between CUR and gut microbiome in CKD remains unclear.

Chronic kidney disease (CKD) is a conceivable new risk factor for cognitive disorder and dementia. Uremic toxicity, oxidative stress, and peripheral-central inflammation have been considered important mediators of CKD-induced nervous disorders. Nitric oxide (NO) is a retrograde neurotransmitter in synapses, and has vital roles in intracellular signaling in neurons.

Secondary hyperparathyroidism (sHPT) is a significant clinical complication of CKD leading to bone abnormalities and cardiovascular disease. Current treatment based on activating the parathyroid calcium-sensing receptor (CaSR) using calcimimetics such as Cinacalcet, aims to decrease plasma PTH levels and inhibit the progression of parathyroid hyperplasia. In the present study, we found significant diurnal rhythmicity of Casr, encoding the Cinacalcet drug target in hyperplastic parathyroid glands (p = 0.
