Aims And Objectives: To determine correlation between the Salivary Urea levels with that of Blood Urea levels.
Materials And Methods: Subjects were selected from patients undergoing haemodialysis and patients who had underwent kidney transplantation at Ashwini Hospitals Guntur. The study comprised of 45 patients, of which Haemodialysis group (HD) with 20 patients, Transplant (T) group with 15 patients and 10 patients in control group. Samples of blood and saliva were taken from all the patients to assess the Blood Urea Nitrogen (BUN) and Salivary Urea (SU) levels respectively under strict aseptic precautions. Blood was collected just prior to the dialysis in HD group and in renal transplant (T) patients during their review visit. Informed consent was taken from patients and ethical committee approval taken.
Results: There was a statistically significant difference between Blood Urea and Salivary Urea levels in the HD and T group (p<0.05). There was a statistically significant difference between T and Control group with respect to Blood Urea and Salivary Urea levels. The salivary urea levels are slightly higher than blood urea levels in all the study groups.
Conclusion: The salivary urea tests can be used in place of blood tests as a non invasive diagnostic tool. Thus, preventing the unnecessary and periodic withdraw of blood which is not only cumbersome but also leads to recurrent infections.

Salivary heat shock protein 70 as a potential non-invasive biomarker of environmental thermal stress in dairy cattle.
Int J Biometeorol
November 2024
Department of Veterinary Physiology, Madras Veterinary College, Chennai, Tamil Nadu, 600 007, India.
The present study aims to explore the potential biomarker application of salivary heat shock 70 kDa protein in detecting thermal stress in dairy animals noninvasively. The study spans for 45 days during the mid-summer season (April-May), involving twelve multiparous non-pregnant adult Jersey crossbred cows by randomly allocating them into groups (six animals in each group). The control animals were maintained in the shed, whereas the thermal stress group animals were exposed to environment heat between 10:00 h to 16.
View Article and Find Full Text PDFBackground: Ozonated water is expected to be an effective disinfectant for SARS-CoV-2 present on environmental fomites; however, ozone is consumed by organic substances, resulting in attenuation of its effect. SARS-CoV-2 present in saliva can contaminate environmental surfaces; therefore, it is essential to understand the effect of organic substances in saliva on the disinfectant properties of ozonated water.
Aim: To assess organic factors in saliva and the extent to which they diminish the effect of ozonated water on SARS-CoV-2.
Agmatine alleviates diabetic-induced hyposalivation in rats: A histological and biochemical study.
Life Sci
December 2024
Department of Histology and Cell Biology, Faculty of Medicine, Ain Shams University, Cairo 11566, Egypt.
Article Synopsis
- Diabetic patients often suffer from low saliva production, leading to difficulties with eating, swallowing, and an increased risk of gum disease.
- This study tested whether agmatine could enhance salivation in diabetic rats made hyposalivatory through a substance called streptozotocin (STZ).
- Results showed that agmatine improved salivary gland function and reduced the negative effects of diabetes on these glands, suggesting it may help manage hyposalivation.
Salivary Metabolites in Breast Cancer and Fibroadenomas: Focus on Menopausal Status and BMI.
Metabolites
September 2024
Biochemistry Research Laboratory, Omsk State Pedagogical University, 644099 Omsk, Russia.
Unlabelled: This study of the features of the biochemical composition of biological fluids in patients with breast cancer, including saliva, allows us to identify some indicators as metabolic predictors of the presence of the disease.
Objectives: to study the influence of the menopause factor and body mass index (BMI) on the biochemical composition of saliva and to evaluate the applicability of metabolic markers of saliva for the diagnosis of breast cancer.
Methods: The case-control study involved 1438 people (breast cancer, = 543; fibroadenomas, = 597; control, = 298).
Investigating oral microbiome dynamics in chronic kidney disease and post-transplantation in continuous culture.
Microbiol Spectr
November 2024
School of Health Sciences, Faculty of Biology, Medicine and Health, The University of Manchester, Manchester, United Kingdom.
Article Synopsis
- The oral microbiome's composition is affected by environmental factors in chronic kidney disease (CKD) and after kidney transplantation, particularly influenced by urea levels in saliva.
- The study modeled the effects of varying urea concentrations in saliva across different phases: healthy, CKD, and post-transplant, using artificial saliva and observing microbial changes over time.
- Findings revealed stability in microbial communities despite urea fluctuations, with notable increases in certain bacteria (like TG5) in late stages, highlighting the complex relationship between salivary urea and oral health in kidney conditions.
