Insulina tópica en el tratamiento del defecto epitelial persistente posúlcera corneal grave

El tratamiento del defecto epitelial refractario es un reto y está sujeto al desarrollo de estudios preclínicos y clínicos con el objetivo de obtener tratamientos eficaces, entre los que emerge la insulina tópica. El objetivo del presente artículo fue describir la respuesta cicatrizal del epitelio corneal bajo tratamiento con colirio de insulina. Se presentan dos pacientes con diagnóstico de defecto epitelial persistente posúlcera corneal. Se indicó insulina tópica una gota cada 6 horas, con evolución hacia la epitelización corneal total a los 10 días de iniciado el tratamiento. Se sugiere el mecanismo por el cual la insulina promueve la cicatrización corneal al lograr la restauración de los nervios corneales y favorecer la migración de células epiteliales. En ambos casos el colirio de insulina logró la promover la cicatrización epitelial total de la córnea por lo que se es útil en el tratamiento de defecto epitelial persistente.

The treatment of refractory epithelial defect is a challenge and depends upon the development of preclinical or clinical studies aimed at obtaining effective treatments, among which topical insulin emerges. The objective of this article was to describe the healing response of the corneal epithelium under treatment with insulin eye drops. The cases are presented of two patients with a diagnosis of persistent post-corneal ulcer epithelial defect. Topical insulin was prescribed at one drop every six hours, with evolution towards total corneal epithelialization ten days after the treatment started. The mechanism is suggested by which insulin promotes corneal healing, thus restoring corneal nerves and favoring epithelial cell migration. In both cases, the insulin eye drops were able to promote total epithelial healing of the cornea, making it useful in the treatment of persistent epithelial defect.

Safety Evaluation of FONIO (Digitaria exilis)/Ricebean (Vigna Umbellata) Based Complementary Food

This study evaluated the oligosaccharides, phytochemicals, dietary fiber, microbial count, pH and acidity of fonio (Digitaria exilis)/ricebean (Vigna umbellata) based complementary foods in order to ascertain the safety of the formulations. A 3 by 4 by 4 factorial design was used. A 70:30 (treated fonio): (72 h sprouted and dehulled ricebean) blend containing 30 % peeled dried carrot and 30 % crayfish (FNBN) was formulated. A similar blend with additional 20 % milk (FNBP), a third blend containing unsprouted and undehulled ricebean (FNBU) and a fourth containing only treated fonio and sprouted ricebean (FNBM) were also formulated. The level of stachyose and raffinose in the diets ranged from 0.21±0.00 -0.40±0.02 % and 0.05±0.00 -0.10±0.01 % respectively. The levels of stachyose and raffinose in the sprouted samples (FNBP, FNBN and FNBM) were comparable (p>0.05) and low suggesting absence of flatulence. The residual phytochemicals in the formulations ranged from 0.160±0.00-0.28±0.00 % (alkaloid), 0.17±0.02-0.35±0.01 % (flavonoid) and 0.39±0.02-0.530±0.01 % (saponin). These low values indicate absence of allergy. The dietary fiber contents of the blends were lower (p<0.05) than the recommended 5 % for complementary food indicating that the digestive system of the infants can handle it. The low bacterial load and zero fungal growth observed in the products depict high level of hygiene and sanitary quality while the near neutral pH and low acidity suggest caution during handling and feeding of the infant. These conditions favour growth of spoilage and pathogenic microorganisms. Results of the study show a high measure of safety of the formulations.

Evaluation of Antipyretic Activity of Siddha Herbomineral Formulation - Surangusa Parpam

The aim of the present study was to assess the antipyretic activity of Siddha herbo-mineral formulation Surangusa Parpam at the dose level of 15mg/kg and 35mg/kg body weight, orally, in brewer yeast induced fever model Wistar rats. Fever was induced by subcutaneous injection of 10ml/kg of 20% w/v aqueous suspension of brewer’s yeast into the nape of the rat's neck. After eighteen hours feverish animals were treated with Surangusa Parpam 15mg/kg and 35mg/kg body weight, orally, and rectal temperatures were evaluated at 0, 1, 2 and 3 hours post-treatment by inserting a well-lubricated bulb of the clinical thermometer. Surangusa Parpam showed a significant decrease in the elevated body temperature of rats that remained sustained throughout the tested time points from 1 to 3 hours in the used model. 35mg/kg body weight dose level showed significant inhibition of elevated body temperature when compared with the standard control. These results indicate that the Antipyretic activity of Surangusa Parpam and in addition to its well-established anti-inflammatory activity possesses significant antihistamine activity that may be beneficial in symptomatic relief when it is used in the therapy of allergic and inflammatory disorders.

Effect of Calotropis procera (Aiton) Dryand.based zinc oxide nanoparticles on the cotton pest Spodoptera litura Fab

Major loss in agricultural crops is caused by insect pests. In India, various synthetic insecticides are used against pests. These are much expensive and cause environmental hazards. The nanoparticles, as an alternative approach is gaining considerable interest in this field. In the present study, we explored the biological synthesis of zinc oxide nanoparticles using Giant milkweed, Calotropis procera (Aiton) Dryand. and its effects on the tobacco cutworm, Spodoptera litura. The reduction of zinc ions (Zn2+) to zinc nanoparticles (ZnO NPs) was prepared by mixing 50 g of C. procera leaves with 100 mL of single distilled water in a 250 mL glass beaker. To synthesize nanoparticles, 50 mL of C. procera leaf extract was taken using a stirrer-heater and 5 g of zinc oxide was added at 60ºC, boiled, then kept in a hot air oven at 70ºC for 24 h. Finally, the obtained light yellow coloured powder was carefully collected and characterized using X-ray diffraction (XRD) analysis. The results revealed that the biologically synthesized zinc oxide nanoparticles pesticide was highly effective against the pest. The weight of the pest decreased from low concentration to high concentration. It is concluded that the Calotropis Procera based zinc oxide nanoparticles could be used for the control of Spodoptera litura.

Network pharmacology and molecular docking study of the active ingredients in Saptasaram kashayam for the treatment of Polycystic ovary syndrome-Supplemenntary data

Polycystic Ovary Syndrome (PCOS) is one of the most prevalent endocrine disorder in women of reproductive age characterized by hyperandrogenism (HA). Current treatment options for PCOS are either with adverse effects or ineffective. Saptasaram kashayam (SK), an ayurvedic formulation is often been a safe traditional alternative medicine to improve the PCOS symptoms as well as its pathological development. However, its principle phytoconstituents or underlying mechanisms have not been investigated. In order to achieve this, the current study systematically utilized computational tools, network pharmacology approaches and molecular docking studies. All identified phytoconstituents of SK were screened by QikProp ADME prediction and 47 were selected based on oral bioavailability and drug likeliness scores. Their 3D structures were submitted to three online target fishing webservers PharmMapper, ChemMapper and Swiss Target Prediction which produced 1084 biological targets for SK comprehensively. 350 known PCOS therapeutic targets were retreived as common targets from three different interrogative disease centric bioinformatic platforms DisGeNET, OMIM and GeneCards. Intersection of 1084 biological targets of SK and 350 PCOS therapeutic targets produced, 88 potential therapeutic targets of SK against PCOS. STRING PPI and Compound-Target-Pathway networks were constructed and analysed using Cytoscape software. GO & KEGG pathway enrichment analysis was performed using DAVID database. 15 PCOS therapeutic target proteins were short listed from network analysis report- PIK3CA, PDPK1, AKT1, PIK3R1, STAT3, MAPK1, MAPK3, EGFR, AR, ESR1, ESR2, SHGB, NOS3, F2 & CREBBP. Targets that were likely to be inhibited/modulated by SK for treatment of PCOS were docked against the screened phytoconstituents and their respective standard inhibitors using GLIDE-SP of Schrodinger suite, Maestro version- 13.0. Results showed that Quercetin, Catechin, Boeravinone J, Genistein, Protocatechuic Acid, Gentisic Acid, Xanthoarnol, Luteolin, Boeravinone F, Tyrosine, Kaempferol, Dalbergioidin, etc exhibited good binding affinities when compared to standard drugs and might be responsible for synergistic/additive protective effect of SK against PCOS. Meanwhile PI3K-Akt signaling pathway, Prolactin signaling pathway, AGE-RAG diabetic complications, HIF-1 signaling pathway and Estrogen signaling pathway were found to be involving the hub genes of interest and in this way, they might be intervened during treatment of PCOS by SK. Present study succeeded in identifying the drug like principle phytoconstituents, probable PCOS therapeutic targets and the underlying molecular mechanism of SK apart from providing reliable evidence for therapeutic potential of SK against PCOS. However further validation by in vitro and in vivo investigations is necessary.

Study on formulation screening of chloral hydrate oral solution / 药学学报

Chloral hydrate is a commonly used central sedative drug before pediatric clinical examination, but its clinical safety and medication adherence are needed to focus on normally because of its poor stability and palatability. Under the premise of investigating the stability of different formulations, their palatability were also screened by using both human sensory and electronic tongue evaluation techniques. Human sensory evaluation has been conducted with the informed consent of all participants in accordance with the ethical requirements of the Good Clinical Practice for Drug Trials. The results showed that the addition of sorbitol and sucralose could effectively ensure the stability of the oral solution. Sorbitol is the main taste-masking component, and the ratio of 40% sorbitol and 0.5% sucralose can effectively mask the bitterness, astringency and spicy taste of 10% chloral hydrate oral solution. The results detected by human sensory and electronic tongue have good correlation and complementarity, and the combination of these two methods is more conducive to getting objective and reasonable conclusions.

Formulation optimization and analysis of taste-masking effect of licorzine granules based on sensory evaluation and electronic tongue method / 药学学报

Licorzine granules are common preparations for children zinc deficiency. Considering the long course of treatment, the taste of licorzine granules may become a main factor affecting medication adherence. To date there have been no taste evaluation research into licorzine granules yet. In this study, both sensory evaluation and electronic tongue method were utilized to optimize licorzine granules formulations, evaluate the tastes of licorzine, excipients, optimized formulation in vivo and in vitro. As the results show, bitterness and astringency are the main unpleasant tastes generating from licorzine. Xanthan gum is the main taste-masking excipient, lowering down the bitterness and astringency of licorzine by at least one grade. Good correlation exists between the results of sensory evaluation and electronic tongue method, and an integrated combination of the two helps to obtain objective and rational research conclusions. The adult sensory evaluation study was a research-based clinical trial conducted with informed consent from all subjects in accordance with the ethical requirements of Good Clinical Practice.

Formulation Rules in Medical Heart Enlightenment for Treatment of Heart Pain from Perspective of "Tangye Jingfa Tu" / 中国实验方剂学杂志

ObjectiveTo explore the formulation rules for the treatment of heart pain in the Medical Heart Enlightenment （《医学心悟》） from the perspective of the "Tangye Jingfa Tu"， thereby providing a way of thinking about the treatment of heart pain in traditional Chinese medicine （TCM） and the study of the Medical Heart Enlightenment. MethodThe "Tangye Jingfa Tu" contained in the Secrets for Auxiliary Cultivation Life： The Essential Method of Using Herbal Medicine for the Differential Treatment of the Five Zang Organs （《辅行诀五脏用药法要》） was used to analyze the nine prescriptions for heart pain in Volume Ⅲ of the Medical Heart Enlightenment by CHENG Guopeng in the Qing dynasty. A "table for analyzing the formulation of the nine prescriptions for heart pain" was developed. The analysis diagrams for decoction and meridian rules in nine prescriptions for heart pain were plotted and the compatible structure of the medicinal flavors was analyzed. ResultThe composition of Chenxiang Jiangqisan for the treatment of Qi-induced heart pain is "five pungent， four bitter， and two sweet drugs"， the composition of Shouniansan for the treatment of blood-induced heart pain is "five bitter， four pungent， three sweet， and one salty drugs"， the composition of Qingzhongtang for the treatment of heat-induced heart pain is "six bitter， three pungent， and two sweet drugs”， the composition of Jiangfutang with Cinnamomi Cortex for cold-induced heart pain is "three pungent and two sweet drugs"， the composition of Xiaobanxia modified with Fuling Tang for treating fluid retention-induced heart pain is "two pungent and two sweet drugs"， the composition of Baohetang for treating heart pain due to dietary stagnation is "five sweet， four pungent， four bitter， and one sour drugs"， the composition of Guipitang for the treatment of deficiency-induced heart pain is "eight sweet， four bitter， three pungent， and one sour drugs"， the combination of Huachongwan for the treatment of worm-induced heart pain is "seven bitter， six pungent， and four sweet drugs"， the composition of Shenzhusan， Congbaijiu， and Shengjiangtang for the treatment of resistance-induced heart pain is "eight pungent， four bitter， and two sweet drugs". ConclusionFrom the perspective of the "Tangye Jingfa Tu"， the Medical Heart Enlightenment is based on the compatibility principle of "pungent-bitter-sweet drugs" in the treatment of heart pain， with heart deficiency treated with salty drugs for tonifying， or bitter-sweet-salty drugs， and heart excess treated with bitter drugs for purging， or sweet-pungent-bitter drugs， mostly applying the transformation rules of five medicinal flavors， i.e.， "sweet-pungent-bitter drugs" and promoting the action of the pungent and sweet drugs acting on the spleen into the heart to relieve and purge the heart. In most cases， the treatment focuses on harmonizing the heart， liver， spleen， and kidneys， with an emphasis on the mother-child relationship and the application of the principles of the five elements generating and controlling each other. If the progression of the disease involves both the mother and child organs， the formulation should adhere to the compatibility rule of "the child organ makes the mother organ excess and the mother organ makes the child organ deficient".

Formulation of expert consensus on clinical application of external ethnic medicine: taking Baimai Ointment as an example / 中国中药杂志

The concept of ethnic medicine is divided into a broad sense and a narrow sense. The broad concept refers to the traditional medicine of the Chinese nation, and the narrow concept refers to the traditional medicine of Chinese ethnic minorities. The external medicine is one of the main forms of ethnic medicine, and it is also the important content of ethnic medicine for external use, which is widely used in clinical practice. As the theory of ethnic medicine is unique, the application methods have certain characteristics, which are the key technical parts of clinical practice. However, the existing traditional Chinese medicine consensus formulation me-thods cannot meet the needs of the consensus formulation of the external ethnic medicine. Therefore, the methods suitable for expert consensus on external ethnic medicine are required. This article took Expert opinion on clinical application of Baimai Ointment as an exa-mple, and explorde a reasonable, effective, multi-dimensional, and multi-stage method to formulate expert consensus on the external ethnic medicine. In this research, three-dimensional sources of information, including ancient classics, clinical research evidence, and expert application experiences, were systematically and scientifically collected. After organization and analysis, the information was formed into comprehensive evidence. In a formal consensus meeting, part of the recommendations reached consensus. As to the issues that did not reach agreement, in-depth interviews were used to explore the reasons for the differences and resolve the disagreements. Finally, unanimous recommendations were reached. There are common problems during the formulation process of Expert opinion on clinical application of Baimai Ointment. This study is expected to provide references for the formulation of expert consensus on other external ethnic medicine.

Abstract This study aimed to develop and evaluate the stability of sulfadiazine sugar-free extemporaneous oral suspensions, focusing on treating congenital toxoplasmosis. The excipients were carefully chosen to obtain safe products for the pediatric population. Sulfadiazine suspensions (100 mg/ mL) were prepared from the raw material or tablets, stored in amber glass bottles at 5±3ºC, and evaluated at 0, 14, and 30 days. An ultra-performance liquid chromatographic method was developed and validated to assay the drug. The particle size ranged from 29.3 to 50.6 µm, with some variation over the study; pH values around 7.0 and non-Newtonian behavior were observed without modification in the period. Formulations showed a fast dissolution rate (>80% in 15 minutes) without variation over the study. The drug assay was about 100% of the label claimed throughout the study, demonstrating the chemical stability and the preparations' dose homogeneity. The microbiological investigation indicated that both preparations met the requirements for the microbial count and absence of pathogens. In conclusion, the developed formulations can be used for 30 days when stored under refrigeration. The oral suspensions produced are easy to prepare and contain safe components, providing an alternative for congenital toxoplasmosis treatment in children.

Physicochemical Analysis and Chromatographic Profiling Using LC-MS of Kanjika During Fermentation

Kanjika is a traditional Ayurvedic fermentation product prepares using 11 herbal ingredients in an aqueous media without the addition of any sweetening agents. The aim of the study was to analyse the biochemical changes happening throughout the process of fermentation in Kanjika and to identify the bioactive molecules formed during the fermentation process. Two batches of Kanjika were prepared. One batch was kept undisturbed throughout the fermentation process, while samples were drawn out at regular intervals from the other batch. A comparative evaluation of physicochemical parameters was done between the various samples drawn from the second batch of the formulation and the sample from the first batch after completion of fermentation. Further detailed analysis of the product before initiation of fermentation and after completion of fermentation was done using LC-MS. The two batches of Kanjika showed significant changes with regard to basic physicochemical parameters. It was found that in both the batches the pH was found to be highly acidic without any significant variations among the samples. Brix value was significantly high at the end of fermentation, in the sample from the undisturbed batch when compared to the sample from the disturbed batch.

Novel pyriproxyfen based treatment for Aedes breeding control through a long-lasting formulation: Laboratory and field trials in Western Maharashtra, India

Background & objectives: There is a need to evaluate novel techniques for dengue control in India. Several formulations of pyriproxyfen have been assessed for efficacy and duration of action. Pyriproxyfen is also used as a microencapsulated ready-to-use formulation against the Aedes vector. We evaluated a novel pyriproxyfen-based microencapsulated formulation. This slow-release, ready-to-use aqueous spray is a larvicidal formulation, and we assessed its efficacy and residual action through laboratory and semi-field trials against Aedes immature stages. Methods: The study was carried out as per the guidelines for laboratory and field/small-scale field testing of mosquito larvicides by the World Health Organization. The evaluation was conducted in laboratory and semi-field conditions from August to December 2018. We tested the novel formulation on three materials (plastic, ceramic, and enamel) in the laboratory for its action as an antilarval. Four containers of each kind were sprayed with the formulation and kept as replicates. Four controls were used in the laboratory trials - 120 larvae (third instar) were introduced in the replicates and the controls each. Readings were taken daily till complete adult emergence or larval and pupal mortality. In the semi-field trials, we applied this formulation to the inside of desert coolers and observed larvicidal and pupicidal activity over five months. Data is presented in numbers and percentages, along with mean and standard deviation. Adult emergence and Emergence Inhibition was calculated. Results: There was 100% adult emergence inhibition amongst the exposed larvae in the treated containers in the laboratory trials. In the untreated controls, adult emergence ranged from 80–95% in all types of containers. In the semifield trials, Inhibition Emergence was 100% in the treated desert coolers during the five months of the study period. Interpretation & conclusion: This advancement in insecticide formulation technology promises to make dengue control more effective and efficient
