RESUMEN

ETHNOPHARMACOLOGICAL RELEVANCE: Ancient Egyptian texts only offer glimpses into their conceptual understandings of the inner-body and illness manifestation. Explanations of how prescribed materia medica were believed to work are rare and obscure, often resulting in modern approximations for ancient terminology such as 'ra-ib'-an ancient Egyptian classification predominantly translated as 'stomach'-leading to misunderstandings of historical texts, and therefore their use of pharmacology. AIM OF THE STUDY: To investigate the ra-ib and the explanatory models of illness from the Egyptian perspective, and to explore the link between these and the prescribed selection of materia medica. To then compare the conceptual mechanics of these treatment strategies with those of another non-Western tradition-namely Traditional Chinese Medicine (TCM)-to provide further insight into potential conceptual frameworks. MATERIALS AND METHODS: We conducted a case study of a unit of Ancient Egyptian texts focusing on the ra-ib. Totalling 34 prescriptions, the first stage lexicographically analysed the texts using cognitive linguistic and translation theories to produce our new understanding. This enabled our comparison of the mechanics of materia medica usage within these texts with those found in TCM outlined by the Pharmacopoeia of the Peoples Republic of Pharmacopeia of the People's Republic of China 2015 for the relevant ingredients. RESULTS: the study demonstrated that-rather than denoting the organ 'stomach'-ra-ib instead constitutes a system running from the mouth, downward to the anus. This is best translated as 'inner thoroughfare', and changes the way in which we attempt to understand potential motivations in the selection of ingredients. By exploring common themes in the use of eleven securely translated ingredients from the Egyptian corpus and the Pharmacopoeia of the People's Republic of China-representing a modern traditional system which understands the body via a series of interconnected systems-we were able to highlight certain themes which might be 'universal' to system-based traditions; this provided new insights into the Egyptian motivations for treatment selection. CONCLUSIONS: Having gained the ancient view of the body and illness, cultural comparisons are important for providing further potential insights and clarifications of a discontinued historical healing tradition. The new understanding of the ra-ib from our study greatly changes the way in which we understand the dynamics of Egyptian ethnopharmacological source material from this period.

RESUMEN

In the course of a scientific cooperation between the German Mummy Project at the Reiss-Engelhorn-Museen, Mannheim (Germany) and the Musée National d'Histoire et d'Art Luxembourg (Luxembourg), an ancient Egyptian mummy head was analyzed using a multidisciplinary approach including radiocarbon dating, ultra-high resolution computed tomography, physical anthropology, forensic medicine and Egyptology. Dated to the Roman Period, the mummy head belonged to an upper-class woman between 25 and 35 years of age. Computed tomography revealed a lethal blunt force trauma affecting the dorsal parts of the parietal bones, below the intact overlaying soft tissue. Moreover, ancient medical treatment was evidenced through localized shaving of the hair on the affected area, which indicates that efforts have been made to keep the woman alive. This astonishing example of homicide demonstrates the enormous scientific benefit brought by the multidisciplinary investigation of mummified bodies and body parts, and sheds light on life, death and medical care of a woman from Roman Period Egypt.

RESUMEN

BACKGROUND: Aside from the fully licensed herbal medicines there are products on the European pharmaceutical market which are registered by virtue of their longstanding traditional use. The normal registration procedure does not apply to them because presently they do not meet the legal requirements for a full license as set out in the relevant European Union Directive. One of these requirements, "proof of tradition", has so far been dealt with in different ways and fails to meet the criteria of good practice. METHOD: This analysis is based on a selective literature search in PubMed and in databases of medical and pharmaceutical history, interviews with licensing experts, a consensus meeting attended by researchers with a background in general medicine, phytotherapy, medical and pharmaceutical history, biometry, ethnopharmacology, pharmacognosy and the pharmaceutical industry. RESULTS AND DISCUSSION: The 2004 EU Directive, which governs the registration of Traditional Herbal Medicinal Products and demands proof of tradition, is a regulatory construct and, above all, the outcome of a political process that has ended in a pragmatic compromise. The concept of tradition applied in the Directive does not sufficiently reflect the semantic breadth of the term. The only condition defined is that a specific commercial preparation needs to have been on the market for 30 years (15 of them inside the EU). Such an approach does not make full scientific use of the evidence available because the information excerpted from historical sources, if adequately processed, may yield valuable insights. This applies to indications, modes of application, efficacy and product safety (innocuousness). Such criteria should enter in full into the benefit-risk-analysis of applied preparations, in the registration process as well as in the therapeutic practice. CONCLUSION: When registering Traditional Herbal Medicinal Products the criterion of evidence-based medicine will only be met if all the facts available are assessed and evaluated, over and above the formally stipulated regulatory provisions (30 years, product reference). To this end, the scientific methods (from among the natural, life or cultural sciences), which are recognized as authoritative in each case, must be applied.

RESUMEN

BACKGROUND: Ziziphus spina-christi (L.) Desf. (Christ's Thorn Jujube) is a wild tree today found in Jordan, Israel, Egypt, and some parts of Africa, which was already in use as a medicinal plant in Ancient Egypt. In ancient Egyptian prescriptions, it was used in remedies against swellings, pain, and heat, and thus should have anti-inflammatory effects. Nowadays, Z. spina-christi, is used in Egypt (by Bedouins, and Nubians), the Arabian Peninsula, Jordan, Iraq, and Morocco against a wide range of illnesses, most of them associated with inflammation. Pharmacological research undertaken to date suggests that it possesses anti-inflammatory, hypoglycemic, hypotensive and anti-microbial effects. The transcription factor NF-κB (nuclear factor kappa-light-chain-enhancer of activated B cells) is critical in inflammation, proliferation and involved in various types of cancer. Identification of new anti-inflammatory compounds might be an effective strategy to target inflammatory disorders and cancer. Therefore, extracts from Z. spina-christi are investigated in terms of their anti-inflammatory effects. Our intention is to evaluate the effects of Z. spina-christi described in ancient Egyptian papyri, and to show whether the effects can be proven with modern pharmacological methods. Furthermore, we determine the active ingredients in crude extracts for their inhibitory activity toward NF-κB pathway. MATERIALS AND METHODS: To determine the active ingredients of Z. spina-christi, we fractionated the extracts for bioassays and identified the active compounds. Epigallocatechin, gallocatechin, spinosin, 6''' feruloylspinosin and 6''' sinapoylspinosin and crude extracts of seed, leaf, root or stem were analyzed for their effect on NF-κB DNA binding by electromobility shift assay (EMSA) and nuclear translocation of NF-κB-p65 by Western blot analysis. The binding mode of the compounds to NF-κB pathway proteins was compared with the known inhibitor, MG-132, by in silico molecular docking calculations. Log10IC50 values of gallocatechin and epigallocatechin as two main compounds of the plant were correlated to the microarray-based mRNA expression of 79 inflammation-related genes in cell lines of the National Cancer Institute (NCI, USA) as determined. The expression of 17 genes significantly correlated to the log10IC50 values for gallocatechin or epigallocatechin. RESULTS: Nuclear p65 protein level decreased upon treatment with each extract and compound. Root and seed extracts inhibited NF-κB-DNA binding as shown by EMSA. The compounds showed comparable binding energies and similar docking poses as MG-132 on the target proteins. CONCLUSION: Z. spina-christi might possess anti-inflammatory activity as assumed by ancient Egyptian prescriptions. Five compounds contributed to this bioactivity, i.e. epigallocatechin, gallocatechin, spinosin, 6''' feruloylspinosin and 6''' sinapoylspinosin as shown in vitro and in silico.

RESUMEN

Balanites aegyptiaca (Balanitaceae) is a widely grown desert plant with multiuse potential. In the present paper, a crude extract from B. aegyptiaca seeds equivalent to a ratio of 1 : 2000 seeds to the extract was screened for antiplasmodial activity. The determined IC(50) value for the chloroquine-susceptible Plasmodium falciparum NF54 strain was 68.26 µg/µL ± 3.5. Analysis of the extract by gas chromatography-mass spectrometry detected 6-phenyl-2(H)-1,2,4-triazin-5-one oxime, an inhibitor of the parasitic M18 Aspartyl Aminopeptidase as one of the compounds which is responsible for the in vitro antiplasmodial activity. The crude plant extract had a K(i) of 2.35 µg/µL and showed a dose-dependent response. After depletion of the compound, a significantly lower inhibition was determined with a K(i) of 4.8 µg/µL. Moreover, two phenolic compounds, that is, 2,6-di-tert-butyl-phenol and 2,4-di-tert-butyl-phenol, with determined IC(50) values of 50.29 µM ± 3 and 47.82 µM ± 2.5, respectively, were detected. These compounds may contribute to the in vitro antimalarial activity due to their antioxidative properties. In an in vivo experiment, treatment of BALB/c mice with the aqueous Balanite extract did not lead to eradication of the parasites, although a reduced parasitemia at day 12 p.i. was observed.

RESUMEN

Starting point of this article is a problem obvious to anybody who reads the medical papyri of ancient Egypt from the New Kingdom and the Late Period: the prescriptions contain two dyadic systems of notation for measures of capacity without specifying the unit of measurement, firstly the Horus eye fractions 1/2, 1/4, 1/8, 1/16, 1/32 and 1/64 which are unanimously assumed to refer to the single Heqat and secondly the, normal' dyadic fractions from 1/2 to 1/128, which have been interpreted in widely different ways, as fractions of the Henu-, the Ro-, the single Heqat-, the 5-Ro- or the Dja-measure, respectively. Interpretations suggested in translations and commentaries have remained inconclusive and unsatisfactory.
