Background: Diabetes is a complex metabolic disease manifested by raised glucose levels in the blood and impaired insulin function leading to various organ complications, including diabetic nephropathy. Baicalin, a flavonoid derived from Scutellaria baicalensis Georgi, has garnered substantial attention for its diverse beneficial effects, including anti-inflammatory, anti-allergic, anti- apoptotic properties, etc. Intriguingly, in vivo studies in rats have further unveiled baicalin’s potential to directly modulate pancreatic beta cells, suggesting a promising role as an anti-diabetic agent.Objective: The purpose of this study is to comprehensively explore the anti-diabetic effect of baicalin, focusing on key parameters such as plasma insulin levels, glucose levels, hemoglobin, and glycated hemoglobin levels in streptozotocin-induced diabetic rats. Additionally, we sought to explore Baicalin’s ability to provide renal protection by evaluating serum renal markers. Methodology: This study involved a total of 30 Wistar albino male rats. Diabetes was created in rats by a single intraperitoneal streptozotocin injection (40 mg/kg). After 72 hours, the rats with diabetes were segregated into four treatment groups (Group II to Group V) comprising 6 animals each. Group I consists of six normal control rats (without diabetes). The groups received different treatment protocols, including normal saline, DMSO, Baicalin (50 mg/kg/day), and glibenclamide (6 mg/kg/day) for 45 days. Throughout the study, meticulous observations were made regarding the animals’ general appearance, body weight, behavior, and their fasting glucose levels in venous blood.Results: Oral dosing with Baicalin at the rate of 50 mg/kg body weight revealed notable enhancements in insulin secretion and hemoglobin levels, alongside notable reductions in blood levels of glucose and glycated hemoglobin compared to the glibenclamide-treated type 2 diabetic rats. Additionally, Baicalin displayed a protective action on renal tissue, as shown by reduced serum creatinine, uric acid, and urea levels.Conclusion: Our investigation unveils Baicalin’s potential as a promising anti-diabetic agent with the added benefit of renal tissue protection. The observed improvements in various physiological parameters warrant further exploration of Baicalin’s therapeutic mechanisms and clinical applications, presenting it as a compelling candidate for diabetes management and diabetic nephropathy prevention.

Snail mucin (SM) has garnered significant attention in dermatology, particularly for its potential in scar therapy and wound healing, due to its bioactive compounds, like allantoin, glycolic acid, and hyaluronic acid. These compounds are known to promote tissue regeneration, enhance skin hydration, and reduce scarring. However, despite growing interest, significant gaps remain in the clinical understanding of SM's therapeutic potential, including a lack of standardised formulations and limited clinical trials. There is a urgent need for more extensive human clinical trials to fully explore SM's potential in scar therapy, particularly given the potential safety concerns, such as skin irritation, sensitisation, and allergic reactions, these issues highlight the importance of toxicological evaluations and regulatory scrutiny. While current regulatory frameworks, such as from FDA and CIR, emphasise the importance of safety substantiation for SM-based products, no formal toxicological monographs exist. This review discusses the therapeutic relevance of SM, identifies research gaps, and emphasises the need for rigorous safety testing and clinical validation to support its use in dermatology.

Mammary gland tumors are the most commonly diagnosed tumors in domestic dogs. Although immunohistochemical methods provide valuable information such as the location and semi-quantitative data of the interested antigens in particular tumors, conventional methods like histopathological diagnosis remain useful and necessary for identification and classification of tumors. In the present study, we combined histopathology with immunohistochemical staining for progesterone receptor (PR) and special staining argyrophilic nucleolar organizer regions (AgNOR) for cell proliferation in canine mammary gland tumors. Twenty-nine dogs with primary mammary gland neoplasms (11 benign and 18 malignant) were included in this study. All 29 tumors were stained with AgNOR but only 15 cases expressed positive PR signals in the nuclei of neoplastic alveolar and ductal epithelial cells. A weak positive correlation (r = 0.2) was observed between PR and AgNOR index of benign tumors and a very weak negative correlation (r = -0.1833) between PR and AgNOR index of malignant tumors suggesting that higher cellular proliferation is associated with low expression of progesterone receptors.
