Acute pancreatitis (AP) is a life-unpleasant situation with contradictory and inadequate treatments. In this regard, the present study evaluated the effect of the possible pretreatment of lipase-pancreatin on L-arginine-induced AP. Forty adult mice were selected and divided into five groups: I) control group, II and III) AP groups (i.p.) receiving L-arginine of 2×300 and 2×400 mg/100 g body weight (b.w.), IV) AP (2×300 L-arginine) group + pancreatin (mice were i.p. injected by 350 U-lipase), and V) AP (2×400 L-arginine) group + pancreatin (mice were i.p. injected by 350 U-lipase). All AP groups displayed a significant increase in serum levels of ALT, AST, TBARS, and TNF-alpha compared to the control group. Moreover, pancreatic tissue edema, inflammation, and vacuolization of acinar cells were significantly higher in the untreated L-arginine group compared to the control and pancreatin groups. Conversely, the diameter of pancreatic islets significantly declined after induction of pancreatitis compared with control and pancreatin groups. Pancreatin treatment can be used in pancreatic dysfunction, however, this medicine showed no protective effect against L-arginine-induced AP in the mouse model.

Ellagic acid (EA) is a phenolic biomolecule. For its biosynthesis, a source of ellagitannins is required, such as strawberries and yeasts, as precursors of the tannase and β-glucosidase enzymes responsible for hydrolysis of ellagitannins. Two experimental mixture designs were applied., varying the yeast concentration and the number of ellagitannins in the culture medium, evaluating the enzymatic activity and ellagic acid biosynthesis. Aiming to find the optimal compositions of the non-conventional yeasts assessed in the research to biosynthesize ellagic acid feasibly and efficiently using a response surface performing the statistical analysis in the StatGraphics® program for obtaining a higher yield and optimizing the ellagic acid synthesis process, the results indicate that the strains Candida parapsilosis ITM LB33 and Debaryomyces hansenii ISA 1510 have a positive effect on the synthesis of ellagic acid, since as its concentration increases in the mixture the concentration of ellagic acid in the medium also increases; on the other hand, the addition of Candida utilis ITM LB02 causes a negative effect, resulting in the compositions of 0.516876, 0.483124 and 2.58687E -9 respectively, for a treatment under the same conditions, an optimal value of ellagic acid production would be obtained. With an approximate value of 7.33036 mg/mL.
鞣花酸是一种酚类生物分子。其生物合成需要鞣花单宁的来源，如草莓和酵母，作为负责鞣花单宁水解的单宁酶和β-葡萄糖苷酶的前体。采用了两种混合试验设计。在培养基中改变酵母浓度和鞣花单宁的数量，评价酶活性和鞣花酸的生物合成。为了在StatGraphics®程序中利用响应面进行统计分析，以获得更高的产量并优化鞣花酸的合成工艺，寻找本研究中评估的非常规酵母的最优组合，结果表明，菌株假丝酵母(Candida parapsilosis) ITM LB33和Debaryomyces hansenii ISA 1510对鞣花酸的合成有积极的影响。由于鞣花酸在混合物中的浓度增加，培养基中的浓度也随之增加;另一方面，利用念珠菌ITM LB02的添加对鞣花酸产生负作用，其组成分别为0.516876、0.483124和2.58687E -9，在相同的处理条件下，鞣花酸产量达到最佳值。近似值为7.33036 mg/mL。

The aim of this study is to provide a real picture of the disease burden of Prameha in society. The study was performed in Government Ayurved College and Hospital, Nagpur, Maharashtra during Oct 2015-Mar 2016. Total 60 patients of newly diagnosed type 2 diabetes mellitus attending the Kayachikitsa Opd of GAC Nagpur were included for the study. The subjects details were recorded in case report form. The CRF included many variables such as sociodemographic factors, presenting symptoms, risk factors such as hypertension, obesity and glycaemic status, family history of diabetes and physical activity. Other parameters like BMI, glycosylated haemoglobin, fasting and post prandial blood sugar and fasting lipid profile were documented. Descriptive and bivariate analyses were carried out using the XLSTAT software (2020). Amongst 60 subjects, 65% were male and 93.3% were adults. 78% of subjects were following sedentary lifestyle and 40% had family history of diabetes. The results revealed that, obesity, family history of diabetes, uncontrolled glycemic status, sedentary lifestyles, and hypertension were prevalent among the Prameha subjects. The characterization of this risk profile and early detection of prameha by observing poorvarupa will contribute to designing more effective and specific strategies for screening and controlling Prameha in Maharashtra, India.

Piper nigrum (black pepper) is used in Indian traditional medicine and its main alkaloid, Piperine (PIP), presents antioxidant, antitumor and neuroprotective pharmacological properties. This substance is insoluble in aqueous media and can irritate the gastrointestinal tract. Aiming to avoid these inconvenient characteristics and enable PIP oral administration, this study suggested the PIP microencapsulation through the emulsion-solvent evaporation method and the preparation of microparticulated tablets by direct compression. An UV-spectroscopy method was validated to quantify PIP. Microparticles and microparticulated tablets were successfully obtained and the microparticles exhibited excellent flow. The scanning electron microscopy images showed that PIP microparticles were intact after compression. The in vitro release showed a controlled release of PIP from microparticles and PIP microparticles from tablets in comparison to PIP and PIP tablets. The release profiles of PIP microparticles and the microparticulated tablets were similar. Therefore, tablets containing PIP microparticles are promising multiparticulated dosage forms because a tablet allows microparticles administration and the intact ones promote a controlled release, decreasing its irritating potential on the mucosa.

Abstract The anecdotal use of Alternanthera sessilis L. as a relief for diabetes has been known in the Philippines for generations, and antidiabetic activity of similar varieties in other countries is likewise documented. However, the compounds responsible for this activity remain unclear. This study aims to isolate the anti-hyperglycemic fraction of local A. sessilis leaves and identify the compounds in this fraction. Methanol extract of A. sessilis leaves and its hexane, ethyl acetate (ASE), and water fractions were administered to alloxan-induced diabetic mice. ASE (250mg/kg) had the highest anti-hyperglycemic activity at 6-h post-treatment (25.81%±12.72%), with almost similar blood glucose reduction rate as metformin (30.13±3.75%, p=0.767). Repeated fractionation employing chromatographic separation techniques followed by in vivo anti-hyperglycemic assay yielded partially purified subfractions. A. sessilis ethyl acetate subfraction 4-2 (100mg/kg) displayed remarkable suppression of blood glucose rise in diabetic mice at 6-h post-treatment (26.45±3.75%, p<0.0001), with comparable activity with metformin (100mg/kg, 27.87±5.65%, p=0.652). Liquid chromatography/mass spectrometry showed eight distinct peaks, with four peaks annotated via the Traditional Chinese Medicine library and custom library for A. sessilis. Among these, luteolin, apigenin, ononin, and sophorabioside were identified as putative compounds responsible for the anti-hyperglycemic activity. This result provided basis for the reported anecdotal claims and potential utility of the local variety of A. sessilis leaves as sources of anti-hyperglycemic agents.

The hydroelectrolytic beverages segment has been expading its market and introducing new flavors in order to meet the demand for new products. However, experimental studies find concerns about the chemical compositions of these drinks. The aim of this study was to develop a drink without synthetic coloring or flavoring, with functional attributes based on the bacaba ( Oenocarpus bacaba Mart.) peel extract. Two hydroelectrolytic drinks were developed, one hypotonic and the other isotonic, containing 0.5 and 1.0% of bacaba peel extract. Physicochemical characterization, determination of total phenolic compounds, anthocyanins, and antioxidant capacity were perfomed, in addition to color evaluation, as well as sensory analysis by means of preference tests. The developed formulations showed potential antioxidant activity and natural red coloring due to the phenolic compounds and anthocyanins present in the beverages. The sensory evaluation indicated positive acceptance by the tasters regarding the addition of the bacaba peel extract to the beverage formulations. The developed formulations demonstrated that the use of the bacaba peel is a viable option for the production of sports drinks, acting as a natural dye and offering health benefits due to its bioactive compounds.

The purpose of the present study was to develop stable lyophilized formulation of peginterferon alfa-2b which is acquiescent to the short lyophilization process. The present study evaluates the effect of buffering components and cryoprotectant(s) on depegylation of the peginterferon alfa-2b in combination with lyophilization process. Finally, a short lyophilization process was identified which can produce a stable pharmaceutical form of peginterferon alfa-2b without any depegylation during long-term storage. Formulations were analyzed mainly for depegylation by HP-size exclusion chromatography and in-vitro antiviral activity. Residual moisture content in the lyophilized product was also used as a key indicating parameter to check its role with respect to depegylation upon storage under various temperature conditions. It was observed that the peginterferon alfa-2b when formulated in presence of cryoprotectant like sucrose requires longer lyophilization process of about 5 days, irrespective of the buffering components used, to reduce the level of residual moisture content and thereby to produce the stable formulation without depegylation. A stable formulation in presence of high concentration of lactose as a cryoprotectant was developed which can withstand stresses exerted to protein-polymer conjugate during lyophilization phases without any significant depegylation. A short lyophilization process of about 48 hours can be utilized for peginterferon alfa-2b when formulated in presence of lactose as a cryoprotectant through which a stable lyophilized formulation can be produced as against longer process required when sucrose is used a cryoprotectant, which is essential from commercial point of view as lyophilization is a costly process.
