Zootechnical, Pharmacological Uses and Chemical Composition of <i>Napoleonaea vogelii</i>Hook &Planch (Lecythidaceae) in West Africa<br/>—A Review

Napoleonaea vogelii, Lecythidaceae family is a tropical evergreen shrub widely distributed in the coastal regions of West African countries including Benin. It is a medicinal plant whose leaves and bark are of great utility in traditional medicine. Despite its importance, it is little used in ethnoveterinary medicine and its pharmacological basis in this field and especially in the treatment of parasitic diseases caused by Haemonchus contortus is very little documented. This review aims to synthesise existing data on the chemical composition, pharmacological and zootechnical usefulness of N. vogelii and to identify the gaps of these works in order to propose research perspectives. Google Scholar database was used to gather the majority of useful information available on N. vogelii. The results showed that of the 23 publications included in the present study, 60.87% dealt distinctly with the pharmacological properties of N. vogelii. These properties include anthelmintic, antidiabetic, wound healing, antimicrobial, antibacterial, anti-inflammatory, antioxidant properties and N. vogelii contains many secondary metabolites including alkaloids, tannins, flavonoids, saponins, glycosides which give it its pharmacological properties. The Correspondence Factor Analysis performed for the variables extracts and chemical compounds showed that the presence of a given chemical compound is not dependent on the type of extract. This work has gathered information on N. vogelii and found that the species has powerful therapeutic potentials but very little use in traditional veterinary medicine. More research is needed on this plant to make available ethnoveterinary pharmacological data to enable proper use in the treatment of animal diseases in general and gastrointestinal parasitosis of small ruminants in particular.

Application of Well-Known Antiviral Drugs in the Field Formed by the Unexplained Properties of Low-Level Laser Radiation in Therapy of Covid-19 and Chronic Viral Hepatitis

Low-level laser therapy (LLLT) or cold laser has been used in medicine for several decades. However, the method utilizes a direct contact of the light beam with a patient. Further research resulted in development of another method that enables remote transmission of the pharmacological properties of a medicament into a human body with the application of low-level laser radiation as the light source. 18 patients with different viral diseases were treated with the antiviral drugs placed into the field formed by the unexplained properties of low-level laser radiation of the “device for transfer of the pharmacological properties of a drug into the patient’s body”. This resulted in improvement of the patient’s condition, the absence of side effects and adverse reactions when using drugs in the proposed device and shortened therapy period for patients with chronic hepatitis C infection and Covid-19 patients. The long-term follow-up of the patients with chronic hepatitis B infection showed that hepatitis B virus remained at low replication levels under the influence of the therapy, which made it possible to avoid such formidable complications of the disease as cirrhosis of the liver and liver cancer.

A new explanation to homeopathy:analysis of the pharmacological property of homeopathic remedies

Although the biological system is a combination of different chemical processes,many of the mechanisms can not be explained by general chemical processes.Therefore,as a driving force of biological system,a distinct entity called'vital force'can be imagined.But this is not essential to explain homeopathy.From the analysis of different phenomena it apparent that biological system has a tendency to maintain a balanced state.Such a good example is catch-up growth.A stimulus is required to disrupt the balance.This stimulus must enter the body from outside or in case of disease it must arise from within inside.This is the primary stimulus.Infection,chronic poisoning,etc.help the expression of the internal stimulus.These are secondary stimulus.The active dose of similar drug acts on the terminal site of the disease process.This causes the actual reversal of the disease process.Allopathic dissimilar drugs act on different stages of the disease process and alter the course of the disease process.The effect of allopathic drugs does not destroy the effect of disease and compete with the effect of the disease.Potentized homeopathic remedies neutralize the effect of disease but do not alter the course of the disease.As a result,either symptoms of the disease are neutralized or the disease process is accelerated.Different other phenomena support that the property of the potentized remedy is not similar to the original substance.It is a new property which is negative pharmacological property.

Health promoting activities and corresponding mechanism of(–)-epicatechin-3-gallate

(–)-Epicatechin-3-gallate(ECG),a bioactive polyphenolic compound,has contributed a lot to the health benefits of green tea.Great attention has been focused on(–)-epigallocatechin-3-gallate(EGCG),but limited research has been performed towards ECG.Like EGCG,ECG also possesses various pharmacological and physiological properties,such as mediation of antioxidant activities,anti-inflammation response,regulation of cell proliferation and apoptosis,as well as anticancer properties during angiogenesis,invasion and metastasis stages.Nontoxic ECG has various molecular targets within the cells,including CYP enzymes,phaseⅡdetoxification and antioxidant enzymes,as well as pro-inflammatory mediators.The antineoplastic mechanism contains inhibition of phase 1 CYP enzymes,induction of phaseⅡdetoxification and antioxidant enzymes,high anti-inflammatory efficacy,arrest of cell cycle progression,regulation of apoptosis,as well as mediation of metastasis processes.In particular,the gallate moiety of ECG is critical for mediating inhibitory effects towards cancer cells.Besides regulation of intracellular signaling pathways,ECG also inhibits RNase A and matrix metalloproteinase enzymatic activity via chelating metals(copper and zinc)in cancer cells.This review has summarized recent studies on pharmacological properties of ECG,and discussed corresponding mechanism on modulation of cellular signaling events by ECG,hoping to broaden its multiple usage.
