Connaissances, attitudes et pratiques des tradipraticiens de la sante de la ville d'Abidjan sur le paludisme.

INTRODUCTION : An estimated 300 to 500 million clinical cases of malaria occur each year worldwide, 90% in Africa, mostly among young children. In Cote d'Ivoire, malaria is 46.03% of disease states and 62.44% of hospital admissions. In children under 5 years, it is 42.67% of the reasons for consultation and 59.68% of hospital admissions. In pregnant women, it represents 22.91% of disease states and 36.07% of hospital admissions. In Africa, traditional medicine is the first resort for the vast majority of people, because of its accessibility both geographically, economically and culturally. However, some modern practitioners show an attitude of distrust of traditional medicine and its players, calling them irrational. This work had set out to assess knowledge, attitudes and practices of traditional healers in the uncomplicated and complicated in the context of collaboration between traditional and modern medicine for the optimal management of critical cases. MATERIALS AND METHOD : The study focused on traditional healers practicing in the city of Abidjan. The study was conducted using individual interviews over a period of 30 days. The interviews were conducted in local languages, with the assistance, if necessary, translators. For data collection, we used a questionnaire containing four items: the socio-demographic characteristics of traditional healers, their knowledge on malaria, diagnostic practices and traditional therapies. RESULTS : Of the 60 healers and included in the study, only six were women (10%), a sex-ratio of a woman to 9 men. 66.7% of respondents traditional healers are herbalists and 25% of naturopaths.Only 8.3% were spiritualists. The etiology of malaria most commonly cited by the traditional healers were mosquito bites (16.7%), food (1.7%), solar (1.7%) and fatigue (1.7%) . 25% of traditional healers are associated with mosquitoes, sun and fatigue. Symptomatology most cited were fever (100%), dark urine (86%), the yellow or pale conjunctiva (80%), vomiting (71.7%), nausea (58.3%) and abdominal pain (48.3%). Traditional healers recognized three types of malaria: the white shape, form yellow / red and the black form. Traditional healers malarious patients surveyed were receiving both first (58.3%) than second-line (41.7%). 78.3% of them practiced an interview and physical examination of theirpatients before the diagnosis. In 13.3% of cases they were divinatory consultation. Medications used to treat malaria were herbal in 95% of cases. The main sign of healing was the lack of fever (58.3%). 90%of traditional healers interviewed referring cases of malaria black (severe malaria). This reference is made to modern health facilities (90.2%). 68.3% of respondents practiced traditional healers of malaria prophylaxis among pregnant women and children under 5 years.CONCLUSION : A description of clinical malaria by traditional practitioners in health is not very far from that of modern medicine. Nevertheless, the logics of our respondents are etiological more complex and linked to their cultural context. The management of cases is made from medicinal plants in treatment failure patients are usually referred to modern health facilities. The involvement of traditional healers in the detection and quick reference risk cases can contribute to reducing child mortality due to severe malaria.

An ethnobotanical study of antimalarial plants in Togo Maritime Region.

BACKGROUND: Malaria continues to be of great concern in Togo, as it accounts for high mortality rates, principally in children. Although plant-based medicines are the only means in major malarious regions of the country, still very little is known about the medicinal plants and medical practices of the indigenous people. OBJECTIVE: The present study aimed to document the indigenous medicinal plant utilization for the management of malaria and related symptoms in Togo Maritime Region. METHODOLOGY: Fifty Traditional Healers (TH) were selected with the help leaders of Togolese Traditional Healers Associations and information on their knowledge on the use of plants for malaria therapeutic purposes was gathered using a semi-structured interviews. RESULTS: After enquiries, 52 plant species belonging to 49 genera and 29 families were recorded. The most represented families were Rubiaceae and Rutaceae with four species each. Traditional healers agreed more in the treatment of malaria (ICF=0.70), fever (ICF=0.33) and anemia (ICF=0.20). For the treatment of malaria, 38.46% (20/52) of the species cited in the study were of high fidelity level (FL=100%). The leaves (58.22%), leafy stem (33.78%) and fruits (8.52%) were the most used parts in concoctions. The main mode of preparation was decoction (69%) and the administration was essentially by oral route (79%) and body-bath (14%). CONCLUSION: The issue of the study showed that Togo Maritime Region TH have a good knowledge of antimalarial plants. However the study must be extend to the whole country to lead to innovative strategies in malaria control. Such results could be a starting point for in vitro antimalarial screenings.

Anti-ulcer, anti-inflammatory and antioxidant activities of the n-butanol fraction from Pteleopsis suberosa stem bark.

Pteleopsis suberosa Engl. et Diels (Combretaceae) is a tree distributed in many African countries. The decoction from the stem bark is orally administered for the treatment of gastric ulcers in traditional medicine. Previous pharmacological studies reported the anti-ulcer activity of extracts from P. suberosa stem bark. In the present study, the anti-ulcer and anti-inflammatory effects of the n-butanol fraction (RBuOH) obtained from a methanol extract of P. suberosa bark were investigated on ethanol-induced gastric ulcers in rats and carrageenan-induced paw oedema in mice. Misoprostol (0.50 mg/kg, p.o.) and indomethacin (8.00 mg/kg, p.o.) were used as positive controls for anti-ulcer and anti-inflammatory activities, respectively. Results showed that RBuOH treatment significantly reduced the incidence of gastric lesions (50 mg/kg, P<0.05; 100 and 200 mg/kg, P<0.01) and restored the decreased levels of total sulfhydryl groups (T-SH) and non-protein sulfhydryl groups (NP-SH) (50, 100 mg/kg, P<0.05; 200 mg/kg, P<0.01) in the stomach homogenate. Moreover, RBuOH treatment attenuated MDA levels as index of lipid peroxidation in gastric mucosa. Administration of RBuOH at the same dosage (50, 100 and 200 mg/kg) reduced significantly (P<0.01) carrageenan-induced paw oedema in dose-dependent manner (from 42.81% to 87.81% inhibition, 5h after carrageenan injection). The anti-inflammatory effect of RBuOH at 200 mg/kg was comparable with that of indomethacin. Finally, RBuOH proved to possess elevated free radical scavenger capacity on 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay (IC(50) 23.48 microg/ml) which may contribute to the observed anti-ulcer and anti-inflammatory activities.

An extract of Lannea microcarpa: composition, activity and evaluation of cutaneous irritation in cell cultures and reconstituted human epidermis.

Lannea microcarpa (Anacardiaceae) is a tropical tree used in African folk medicine and commercial dermopharmaceutical formulations. Fractionation and analysis of its polar extract allowed the identification of 4'-methoxy-myricetin 3-O-alpha-L-rhamnopyranoside, myricetin 3-O-alpha-L-rhamnopyranoside, myricetin 3-O-beta-D-glucopyranoside, vitexin, isovitexin, gallic acid and epi-catechin, as the major constituents. In-vivo assay (the croton oil ear test in mice) showed that the extract had significant anti-inflammatory effect (ID50 = 900 microg cm(-2)) but ten times lower than that of indometacin (ID50 = 93 microg cm(-2)), the non-steroidal anti-inflammatory drug used as reference. Cytotoxicity and cutaneous irritation of the extract and its constituents were investigated. The crude extract and its major components did not affect cell viability in-vitro either in three different cultures (J774. A1, WEHI-164 and HEK-293) of cells grown in monolayers or in the reconstituted human epidermis (RHE, 3D model), nor did they cause release of pro-inflammatory mediators (IL-1alpha) or histomorphological modification of RHE.

Evaluation of the antioxidant properties and bioavailability of free and bound phenolic acids from Trichilia emetica Vahl.

Trichilia emetica Vahl. is commonly used in folk medicine of Mali for the treatment of various diseases. In this study, the content and the antioxidant activity of phenolic acids from Trichilia emetica root were evaluated. Free phenolic acids were extracted with a mixture of methanol and 10% acetic acid. Bound phenolic acids were released using first alkaline and then acid hydrolysis. All fractions were quantified separately by HPLC. After alkaline hydrolysis, a remarkable increase in caffeic acid, ferulic acid, p-coumaric acid, syringic acid, vanillic acid, protocathecuic acid and gallic acid content was observed, showing that most of phenolic acids in the drug are present as bound forms. Moreover, the extracts submitted to alkaline hydrolysis showed high antioxidant properties in two in vitro assays: autooxidation of methyl linoleate (MeLo) and ascorbate/Fe(2+)-mediated lipid peroxidation in rat microsomes. An in vivo study was also performed to investigate the intestinal absorption of phenolic acids after oral administration of Trichilia emetica extracts. Results showed high levels of phenolic acids, free or conjugated to glucuronide, in the plasma of rats treated with the hydrolyzed extract. Due to the absence of chlorogenic acid in plasma samples, the presence of caffeic acid seems to be derived from hydrolysis of chlorogenic acid in the gastrointestinal tract.

Hepatoprotective and antibacterial effects of extracts from Trichilia emetica Vahl. (Meliaceae).

Trichilia emetica Vahl. (Meliaceae) is a tree widely distributed in Tropical Africa. It has been used in Mali folk medicine for the treatment of various illnesses. The aim of this work was to study the hepatoprotective and antibacterial effects of a crude aqueous extract from Trichilia emetica root. An ethyl ether fraction from the aqueous extract was also prepared and studied. We have examined the hepatoprotective activity of the extracts on CCl4-induced damage in rat hepatocytes, their toxicity using the brine shrimp bioassay and their antibacterial activity against clinical isolated bacterial strains, which are commonly responsible for respiratory infections. A preliminary phytochemical analysis showed a high polyphenolic content in the aqueous extract and the presence of limonoids in the ethyl ether fraction. These latter compounds may be considered responsible for the good activity against the bacterial strains tested. Trichilia emetica extracts exerted also a significant (P<0.05) hepatoprotective effect at a dose of 1000 microg/ml both on plasma membrane and mitochondrial function as compared to silymarin used as a positive control. These activities may be a result of the presence of either polyphenols or limonoids. Finally, both the aqueous extract and its ethyl ether fraction did not show toxicity (LC50>1000 microg/ml) in the brine shrimp bioassay.

HPLC-UV/PAD and HPLC-MS(n) analyses of leaf and root extracts of Vismia guineensis and isolation and identification of two new bianthrones.

In order to evaluate the possible use of the leaves instead of the roots of Vismia guineensis as a new source for the traditional use of this drug, the chemical composition of both organs were compared by HPLC-UV/PAD and HPLC-MS analyses. The leaves are analysed here for the first time. The results show the presence of five major classes of secondary metabolites having specific chromophores: anthraquinones, vismiones, flavonoids, xanthones and benzophenones. The molecular weights and characteristic fragments, compared with previous EI or HPLC-MS literature data, allowed the partial identification of the major peaks in the chromatograms. Six additional isomeric bianthrones and one anthraquinone were detected in the dichloromethane extract of the roots after long storage in solution; the targeted isolation of the bianthrones was performed and enabled the identification of two original C-geranyl derivatives. The chemical compositions of the extracts demonstrated that only a minority of the constituents is shared by both organs. Thus, in order to establish a definitive phytoequivalence, additional pharmacological investigations are required.

Hepatoprotective activity of Trichilia roka on carbon tetrachloride-induced liver damage in rats.

Trichilia roka Chiov. (Meliaceae) is a tree widely distributed in tropical Africa. It has been used in Mali folk medicine for the treatment of various illnesses. A decoction of the roots is taken as a remedy for colds and pneumonia, and it is used as a diuretic and in hepatic disorders. We have evaluated the hepatoprotective effects of a decoction of Trichilia roka root on CCl4-induced acute liver damage in rats. Treatment with the decoction showed a significant protective action made evident by its effect on the levels of glutamate oxalacetate transaminase and glutamate pyruvate transaminase in the serum, on the protein content and lipid peroxidation levels in the liver homogenate. Histopathological changes produced by CCl4, such as necrosis, fatty change, ballooning degeneration and inflammatory infiltration of lymphocytes around the central veins, were clearly recovered by the treatment with Trichilia root decoction. On fractionating this extract into diethyl ether-soluble and water-soluble fractions, the activity was retained in the diethyl ether-soluble fraction. Moreover, the administration of decoction prevented a preferential deposition of collagen around the sinusoidal cell layer, which is responsible for the perisinusoidal fibrosis in the early stage of CCl4 damage. This study showed that treatment with Trichilia roka extracts or silymarin (as reference) appeared to enhance the recovery from CCl4-induced hepatotoxicity. The hepatoprotective properties of Trichilia roka may be correlated to polyphenol content of the decoction and its diethyl ether-soluble fraction.

Trichilia roka Chiov. (Meliaceae): pharmacognostic researches.

The dried aqueous extract of Trichilia roka Chiov. (Meliaceae) root was evaluated for its potential antipyretic activity on yeast-induced hyperthermia in rats. The drug showed a significant reduction of body temperature when administered orally at the doses of 0.25, 0.5 and 1.0 g/kg. The antipyretic activity of T. roka was compared to indomethacin treatment (50 mg/kg), used as a reference drug. The results of this study confirm the validity of traditional usage of T. roka as an antipyretic agent. Moreover, micromorphological investigations were carried out by scanning electron microscopy obtaining useful phytognostic elements for the correct identification of the drugs both in scraped and powdered forms because this is of great interest for quality control in basic research and drug production, especially for imported items and for raw material sold by traditional herborists.

Micromorphological investigations on Entada africana Guill. et Perr. (Mimosaceae).

Entada africana Guill. et Perr., known in Mali by the common local name 'Samanéré' in the Bambara language, is one of the traditional Malian medicines prescribed for many illnesses. In the present investigation, micromorphological studies were carried out by scanning electron microscopy on the roots and the leaves. The correct identification of the morphological characters of drugs is of great interest for quality control in basic research and drug production, especially for imported items and for raw materials sold by traditional herbalists.

Effects of Calotropis procera on oestrous cycle and on oestrogenic functionality in rats.

Effects of ethanolic and aqueous extracts of Calotropis procera (Ait.) R.Br. roots, have been studied on oestrous cycle and on some parameters of oestrogenic functionality in rats. Both extracts have been shown to interrupt the normal oestrous cycle in 60 and 80%, respectively, of rats treated. The rats exhibited prolonged dioestrous stage of the oestrous cycle with consequent temporary inhibition of ovulation. The contemporary administration of commercial oestro-progestinic preparation exhibited the same effects in 100% of rats treated. However, the extracts have not demonstrated to possess oestrogenic activity when tested in immature female bilaterally ovariectomized rats.

Effects of Teucrium divaricatum Heldr. ssp. divaricatum decoction on experimental ulcer in rats.

The effects of chronic intragastric administration of the aerial parts decoction of Teucrium divaricatum Heldr. ssp. divaricatum (Labiateae) on experimental acetylsalicylic acid (ASA)-induced ulcer were studied in rats. The ulcer index and histological mucosa regeneration were evaluated. The ulcer index significantly decreased (U.I. 1.7+/-1.5; P<0.05) after treatment with a lyophilized decoction of T. divaricatum (500 mg/kg os), once daily for 7 days, compared to the control (U.I. 11.4+/-2.3). The ultrastructure modifications of gastric mucosa were observed by transmission electronic microscopy (TEM) confirming the antisecretory effect exercised by administration of the T. divaricatum decoction. Treatment with T. divaricatum seems to block up parietal cell acid secretion and to stimulate in the chief cells the formation of zymogen granules.

Antimicrobial activity of Mitracarpus scaber extract and isolated constituents.

The antimicrobial activity of a methanol extract and isolated constituents of Mitracarpus scaber, a species used in folk medicine by West African native people, was evaluated against Staphylococcus aureus and Candida albicans strains. The mitracarpus methanol extract possesses both antibacterial and antimycotic activities (minimum inhibitory concentration-MIC 31.25 and 62.50 microg ml-, respectively). This extract was subsequently fractioned and monitored by bioassays leading to the isolation of seven compounds screened for antibacterial and antimycotic activities. Among these compounds, gallic acid and 3,4,5-trimethoxybenzoic acid inhibited the growth of Staph. aureus (MIC 3.90 and 0.97 microg ml-). 4-Methoxyacetophenone and 3,4,5-trimethoxyacetophenone effectively inhibited C. albicans (MIC 1.95 microg ml-). The other compounds (kaempferol-3-O-rutinoside, rutin and psoralen) which were also isolated showed low antibacterial and antimycotic activities (125-500 microg ml-).

Hepatoprotective properties in the rat of Mitracarpus scaber (Rubiaceae).

The effect of Mitracarpus scaber on carbon tetrachloride-induced acute liver damage in the rat has been evaluated. Results showed that treatment with Mitracarpus scaber decoction resulted in significant hepatoprotection against CCl4-induced liver injury both in-vivo and in-vitro. In-vivo, Mitracarpus scaber pretreatment reduced levels of serum glutamate-oxalate-transaminase (P < 0.01 for 250, 500 and 1000 mg kg(-1)) and serum glutamate-pyruvate-transaminase (P < 0.05 for 250 mg kg(-1) and P < 0.01 for 1000 mg kg(-1)) previously increased by administration of CCl4. In-vitro results indicated that addition to the culture medium of Mitracarpus scaber extracts significantly reduced glutamate-oxalate-transaminase (P < 0.05 for 100 microg mL(-1) and P < 0.01 for 10 and 1000 microg mL(-1)) and lactate dehydrogenase activity (P < 0.05 for 10 microg mL(-1)). Mitracarpus treatment also resulted in a good ( > 93%) survival rate for the CCl4-intoxicated hepatocytes as demonstrated by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide assay. Moreover, as in the in-vitro assay, Mitracarpus scaber had radical-scavenging properties, shown by its reaction with the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical (EC50, the extract concentration resulting in a 50% reduction in the absorbance of DPPH blank solution, = 41.64+/-1.5 microg mL(-1)). The results of this study showed that Mitracarpus scaber had antihepatotoxic potential, a finding which supports the validity of traditional usage of this drug in Mali for the treatment of liver diseases.

Antiulcer activity of Salvadora persica L.: structural modifications.

In previous work we observed that the decoction of Salvadora persica L. possessed significant protective action against ethanol and stress-induced ulcers. This study was designed to confirm the antiulcer activity of Salvadora persica decoction using optical microscopy. The elements of gastric mucosa tended to be reestablished normally in treated rats.

Effects of some Malian medicinal plants on the respiratory tract of guinea-pigs.

Crossopteryx febrifuga, Pteleopsis suberosa and Entada africana are used in Mali traditional medicine for fever and various respiratory diseases. We have investigated the effects of these three drugs in the form of a decoction on the respiratory tract using different experimental models. On citric acid-induced cough in guinea-pigs, the three drugs significantly decreased the number of coughs at the doses of 250 (P < 0.01), 500 (P < 0.05; P < 0.01) and 1000 (P < 0.01) mg kg(-1). The percent inhibition was respectively 62.86, 69.03 and 77.44% for C. febrifuga, 57.80, 53.90 and 61.40% for E. africana, and 37.13, 42.44 and 73.72% for P. suberosa. Codeine phosphate (10 mg kg(-1)) used as reference drug showed an inhibition of 76.32%. E. africana (1000 mg kg(-1)) reduced (65% inhibition) significantly (P < 0.05) bronchoconstriction induced by histamine (99.25% and 34.00% for control and extract, respectively). Furthermore, E. africana (1000 mg kg(-1)) provoked a bronchodilatation response when administered under basal conditions. On antigen-induced bronchospasm, C. febrifuga protected (54% inhibition) sensitized guinea-pigs with a pulmonary ventilation pressure (PVP) of 24.87% (control value < 55.00%). P. suberosa was inactive in both experimental models. The reference drug, disodium cromoglycate (10 mg kg(-1), i.v.) protected significantly (P < 0.05) with a PVP of 12.00% (78% of inhibition). This study confirmed the traditional use of these plants in the treatment of cough and other respiratory disorders.

Effects of Pteleopsis suberosa extracts on experimental gastric ulcers and Helicobacter pylori growth.

Pteleopsis suberosa Engl. et Diels was used in the traditional medicine of Mali for the treatment of gastric and duodenal ulcers. In an ethnopharmacological approach, Pteleopsis suberosa extracts of the stem bark were investigated for antiulcer and antibacterial activity against Helicobacter pylori standard strains and clinical isolates. The decoction, the traditional form of administration of the drug in Mali, and the methanolic extract were active against all the bacterial strains tested. The minimum inhibitory concentrations ranged from 62.5 to 500 microg/ml for the decoction and from 31.25 to 250 microg/ml for the methanolic extract. The results indicate that Pteleopsis suberosa may be a source of compounds with a therapeutic potential against gastric ulcers associated with Helicobacter pylori infections.
