Major Public Health Problem

Background : Diabetes is a major public health problem in the world. It affects each and every part of the human body and also leads to organ failure. Hence, great progress made in the field of herbal medicine and diabetic research. Objectives: Our review will focus on the effect of bioactive compounds of medicinal plants which are used to treat diabetes in India and other countries. Methods: Information regarding diabetes, oxidative stress, medicinal plants and bioactive compounds were collected from different search engines like Science direct, Springer, Wiley online library, Taylor and francis, Bentham Science, Pubmed and Google scholar. Data was analyzed and summarized in the review. Results and Conclusion: Anti-diabetic drugs that are in use have many side effects on vital organs like heart, liver, kidney and brain. There is an urgent need for alternative medicine to treat diabetes and their disorders. In India and other countries herbal medicine was used to treat diabetes. Many herbal plants have antidiabetic effects. The plants like ginger, phyllanthus, curcumin, aswagandha, aloe, hibiscus and curcuma showed significant anti-hyperglycemic activities in experimental models and humans. The bioactive compounds like Allicin, azadirachtin, cajanin, curcumin, querceitin, gingerol possesses anti-diabetic, antioxidant and other pharmacological properties. This review focuses on the role of bioactive compounds of medicinal plants in prevention and management of diabetes. Conclusion: Moreover, our review suggests that bioactive compounds have the potential therapeutic potential against diabetes. However, further in vitro and in vivo studies are needed to validate these findings.

Vernonia Anthelmintica

To investigate a possible methodology of exploiting herbal medicine and design polytherapy for the treatment of skin depigmentation disorder, we have made use of Vernonia anthelmintica (L.) Willd., a traditional Chinese herbal medicine that has been proven to be effective in treating vitiligo. Here, we report that the extract of Vernonia anthelmintica (L.) Willd. effectively enhances melanogenesis responses in B16F10. In its compound library, we found three ingredients (butin, caffeic acid and luteolin) also have the activity of promoting melanogenesis in vivo and in vitro. They can reduce the accumulation of ROS induced by hydrogen peroxide and inflammatory response induced by sublethal concentrations of copper sulfate in wild type and green fluorescent protein (GFP)-labeled leukocytes zebrafish larvae. The overall objective of the present study aims to identify which compatibility proportions of the medicines may be more effective in promoting pigmentation. We utilized the D-optimal response surface methodology to optimize the ratio among three molecules. Combining three indicators of promoting melanogenesis, anti-inflammatory and antioxidant capacities, we get the best effect of butin, caffeic acid and luteolin at the ratio (butin:caffeic acid:luteolin = 7.38:28.30:64.32) on zebrafish. Moreover, the effect of melanin content recovery in the best combination is stronger than that of the monomer, which suggests that the three compounds have a synergistic effect on inducing melanogenesis. After simply verifying the result, we performed in situ hybridization on whole-mount zebrafish embryos to further explore the effects of multi-drugs combination on the proliferation and differentiation of melanocytes and the expression of genes (tyr, mitfa, dct, kit) related to melanin synthesis. In conclusion, the above three compatible compounds can significantly enhance melanogenesis and improve depigmentation in vivo.

This case study illustrates the reduction of severe stuttering by an individually tailored treatment programme. Interventions are derived from a tripartite analysis (Lang, 1971) and include EMG biofeedback, regulated breathing, exposure in vivo to stressful communication situations and cognitive techniques to reduce relapse risk. The role of dysfunctional response system interactions in stuttering is emphasized. Treatment resulted in a marked reduction of stuttering and associated facial contortions during videotaped conversations with strangers and oral reading. Improvement was maintained at one-year follow-up.

A case study is presented of a young woman with an unusual phobia, a fear of babies. Barabasz's (1977) technique of systematic desensitization using psycho-physiological measures was chosen as the main treatment strategy. Difficulties arose as the client was unable to visualise scenes involving babies. Nor could she look at photographs of babies long enough for the hierarchy to be ordered using a psycho-physiological measure (skin conductance). A set of photographs was eventually used for the hierarchy, but it was ordered in terms of the length of time the client could look at the various photographs. Systematic desensitization was carried out using the set of photographs instead of imaginary scenes, together with some in vivo exposure in the latter stages of treatment. At termination the client could approach babies without discomfort. Improvement was maintained at one year follow-up.

Ultrahigh-performance liquid chromatography-quadrupole/time-of-flight mass spectrometry (UPLC-QTOF/MS) was developed for rapid and sensitive analysis of the effect of rice wine on the metabolites of the main components of herbal medicine in rat urine. UsingCornus officinalisas a model of herbal medicine, the metabolite profiles of crude and processed (steaming the crude drug presteeped in rice wine)Cornus officinalisextracts in rat urine were investigated. The metabolites ofCornus officinaliswere identified by using dynamic adjustment of the fragmentor voltage to produce structure-relevant fragment ions. In this work, we identified the parent compounds and metabolites of crude and processedCornus officinalisin rats. In total, three parent compounds and seventeen new metabolites ofCornus officinaliswere found in rats. The contents of the parent compounds and metabolitesin vivovaried significantly after intragastric (i.g.) administration of aqueous extracts of crude and processedCornus officinalis. Data from this study suggests that UPLC-QTOF/MS could be used as a potential tool for uncovering the effects of excipients found in the metabolites of the main components of herbal medicine,in vivo, to predict and discover the processing mechanisms of herbal medicine.

Abstract Post-mortem in situ MRI has been used as an intermediate between brain histo(patho)logy and in vivo imaging. However, it is not known how comparable post-mortem in situ is to ante-mortem imaging. We report the unique situation of a patient with familial early-onset Alzheimer’s disease due to a PSEN1 mutation, who underwent ante-mortem brain MRI and post-mortem in situ imaging only 4 days apart. T1-weighted and diffusion MRI was performed at 3-Tesla at both time points. Visual atrophy rating scales, brain volume, cortical thickness and diffusion measures were derived from both scans and compared. Post-mortem visual atrophy scores decreased 0.5–1 point compared with ante-mortem, indicating an increase in brain volume. This was confirmed by quantitative analysis; showing a 27% decrease of ventricular and 7% increase of whole-brain volume. This increase was more pronounced in the cerebellum and supratentorial white matter than in grey matter. Furthermore, axial and radial diffusivity decreased up to 60% post-mortem whereas average fractional anisotropy of white matter increased approximately 10%. This unique case study shows that the process of dying affects several imaging markers. These changes need to be taken into account when interpreting post-mortem MRI to make inferences on the in vivo situation.
