Effect of PENN-DIABEX, a novel polyherbal formulation, in high fat diet streptozotocin-induced diabetic rats.

Diabetes, a chronic metabolic disorder affecting millions worldwide, presents a significant health challenge characterized by impaired glucose regulation and potential complications. This study examines the antidiabetic effects of a polyherbal formulation (PENN-DIABEX) prepared from five different medicinal plant extracts. The objective is to ascertain its efficacy in managing streptozotocin (STZ) induced diabetes in rats. To accomplish this, six distinct groups of rats were involved five with induced diabetes and one serving as a normal control. Among the diabetic groups, one received no treatment, functioning as the diabetic control group. The remaining three groups were administered PHF in three different doses while the 6th group was given metformin. On the last day of the experiment, all rats were sacrificed, and blood samples were taken in collecting tubes to analyze blood biochemical parameters. Additionally, tissue samples from the liver, kidney, and pancreas were preserved in formalin solution for subsequent histopathological activity. The results of the study revealed that treatment with PHF in diabetic rats led to a significant (P < 0.01) improvement in fasting blood glucose levels (FBG), glycated hemoglobin (HbA1c), and various biochemical markers including LFTs, RFTs, and lipid profiling. Furthermore, the histology of the liver, kidney, and pancreas indicated that the formulation did not induce any metabolic toxicity. Comparative analysis of the antidiabetic effects of PHF with those of metformin, revealed that the PHF showed better results than the standard drug. This suggests its potential utilization as a safer and alternative approach in the treatment of diabetes.

Appraisal of the pharmacokinetic profile, histopathology and stability studies of a fast dissolving oral film based on natural polysaccharide.

The present research is designed to evaluate the pharmacokinetic profile, histological evaluation, and stability studies of an orodispersible film (ODF) of tizanidine (TZ) and meloxicam (MX) prepared from a natural polysaccharide, i.e., xanthan gum. In vivo release study of TZ and MX was performed in rabbits and results indicated the better pharmacokinetics parameters and improved the oral bioavailability when compared to the oral aqueous suspension and solution of TZ and MX, respectively. The intermediate stability studies were performed at 30±2°C and 65±5% RH, whereas, the accelerated stability studies were carried out at 40±2°C and 75±5% RH, respectively for the duration of six months and results indicated that the ODF was stable for six months without any substantial difference in essential physico-chemical parameters, mechanical attributes, and morphological constraints. The toxicity profile of ODF was determined through histopathology of vital organs after administering the ODF to the rabbits. Histopathology revealed that the tissues of all vital organs are normal and did not exhibit any abnormalities, lesions, or hemorrhage. Therefore, the ODF prepared from xanthan gum exhibited a non-toxic and stable formulation with a better pharmacokinetics profile of MX and TZ.

The avenue of fruit wastes to worth for synthesis of silver and gold nanoparticles and their antimicrobial application against foodborne pathogens: A review.

The emerging fruit wastes valorization tactic is a strategy for minimizing the dependence on toxic solvents and chemicals commonly used in the preparation of nanoparticles (NPs). Furthermore, the NPs have exhibited promising antimicrobial applications against foodborne pathogens. Hence, a timely review of this topic is in demand to provide a clear insight into the subject. In this article, the synthesis of silver and gold NPs from fruit wastes and their antimicrobial application against foodborne pathogens are reviewed. The extraction method, mechanism of NPs formation and influences of various experimental parameters on the shape and size of the NPs are described. In the second part of the article, antimicrobial activities against foodborne pathogens regarding the nature, optimum composition, surface structure, synergism and morphology of the NPs are reviewed. Furthermore, challenges and future trends related to the synthesis and antimicrobial application of fruit wastes-mediated NPs are discussed.
