[Ab] Resumo:Consumption of ackee (Blighia sapida) and lychee (Litchi chinensis) fruit has led to severe poisoning. Considering their expanded agricultural production, toxicological evaluation has become important. Therefore, the biochemical effects of eating 1 g/kg canned ackee, containing 99.2 µmol/kg hypoglycin A, and 5 g/kg canned lychee, containing 1.3 µmol/kg hypoglycin A, were quantified in a self-experiment. Using ultra-high-performance liquid chromatography/mass spectrometry, hypoglycin A, methylenecyclopropylacetyl-glycine, and methylenecyclopropylformyl-glycine, as well as the respective carnitine conjugates, were found in urine after ingesting ackee. Hypoglycin A and its glycine derivative were also present in urine after eating lychee. Excretion of physiological acyl conjugates was significantly increased in the ackee experiment. Ingestion of ackee led to up to 15.1 nmol/L methylenecyclopropylacetyl-glycine and traces of methylenecyclopropylformyl-carnitine in the serum. These compounds were not found in the serum after eating lychee. Hypoglycin A accumulated in the serum in both experiments.

[Ti] Título:Colistin-associated Acute Kidney Injury in Severely Ill Patients: A Step Toward a Better Renal Care? A Prospective Cohort Study.

[Ab] Resumo:BACKGROUND: Critically ill patients with severe sepsis or septic shock may need relatively high colistin daily doses for efficacy against multidrug-resistant and extensively drug-resistant gram-negative rods. However, acute kidney injury (AKI) may represent a major dose-limiting adverse effect of colistin. We sought to determine AKI occurrence and to identify factors influencing AKI risk in severely ill patients receiving colistin according to a recently proposed dosing strategy. METHODS: A prospective, observational, cohort study involving patients with severe sepsis or septic shock who received colistin was performed. AKI was defined according to Acute Kidney Injury Network criteria. Colistin administration was driven by a modified pharmacokinetics-pharmacodynamics (PK/PD)-based dosing approach. RESULTS: Of 70 patients who received colistin at a median daily dose of 9 million IU (MIU; interquartile range, 5.87-11.1 MIU), 31 (44%) developed AKI. In univariate analysis, age, Acute Physiology and Chronic Health Evaluation (APACHE) II score, Sequential Organ Failure Assessment (SOFA), score and baseline renal impairment were significantly associated with AKI. Moreover, patients with AKI were less frequently treated with adjuvant ascorbic acid (P = .003). In multivariate analysis, independent predictors of AKI were baseline renal impairment (adjusted hazard ratio, 4.15; 95% confidence interval, 1.9-9.2; P < .001) and age (1.03; 1.0-1.05; P = .028), whereas a strong independent renal-protective role emerged for ascorbic acid (0.27; .12-.57; P < .001). CONCLUSIONS: In severely ill patients receiving colistin according to a PK/PD-driven dosing approach, baseline renal impairment and older age strongly predict AKI occurrence, but concomitant administration of ascorbic acid markedly reduces AKI risk, allowing safer use of colistin.

[Ab] Resumo:Ackee apple fruit is a native fruit to Jamaica and some parts of west Africa. Its toxicity known as "Jamaican vomiting sickness" dates back to the nineteenth century. However, there is a dearth of reported published data on toxicity from Nigeria where it is popularly known in the southwest as "ishin." We report a case series of eight previously well Nigerian siblings who presented at various intervals after ingestion of roasted seeds and aril of the ackee fruit.

[Ab] Resumo:The maturation of fruits is characterized by numerous compositional changes during ripening and these changes contribute in their quality attributes. This study aimed to assess the contents of saccharides and potential fructooligosaccharides (FOS) of ackee (Blighia sapida Köenig), carambola (Averrhoa carambola) and June plum (Spondias dulcis), at green and ripe stages. Beside glucose and fructose and lower sucrose content, three short chain fructooligosaccharides were identified in ackee fruit, namely 1-kestose (1(F)-ß-d-fructofuranosyl sucrose), nystose (1(F)(1-ß-d-fructofuranosyl)2 sucrose) and DP5 (1(F)(1-ß-d-fructofuranosyl)3 sucrose), while in carambola and June plum DP5 (1(F)(1-ß-d-fructofuranosyl)3 sucrose) was not detected. Ripening stage also affected significantly the contents of these saccharides and sFOS.

[Ab] Resumo:ETHNOPHARMACOLOGICAL RELEVANCE: Blighia sapida leaves are used in the management of diabetes in Nigeria. Thus the antidiabetic activity of methanolic Blighia sapida leaf extract and its capability to halt oxidative stress and dyslipidemia in alloxan-induced diabetic rats were investigated. METHODS: In vitro antioxidant activity of the extract (0.2-1.0mg/mL) was investigated using 2,2-diphenyl-1-1picrylhydrazyl (DPPH) radical, superoxide ion, hydrogen peroxide, and hydroxyl radical and ferric ion reducing system. Antidiabetic was evaluated in alloxan-induced diabetic rats. RESULTS: The methanolic extract of Blighia sapida leaves at 1.0mg/mL scavenged DPPH, superoxide ion, hydrogen peroxide, and hydroxyl radical at 80.34%, 57.39%, 72.36% and 77.0% respectively, while ferric ion was significantly reduced. Single oral dose of the extract significantly reduced blood glucose level in a dose dependent manner with highest dose producing 18.6% reduction after 240min. Similar reduction was produced after 28 days of extract administration with the highest dose producing 65.65% reduction which compared significantly (P<0.05) with the control group and glibenclamide treated groups. Alloxan-induced diabetic mediated alterations in liver and serum cholesterol, triacylglycerides, high-density lipoprotein cholesterol (HDLc), low density lipoprotein (LDL) cholesterol and very low-density lipoprotein cholesterol (VLDLc) were significantly (P<0.05) restored by the extract. Methanolic extract of Blighia sapida leaves significantly attenuated the decrease in the activities of reactive oxygen species detoxifying enzymes (superoxide dismutase, catalase, glutathione peroxidase, glutathione reductase and glucose 6-phosphate dehydrogenase) in the liver and pancreas of alloxan-induced diabetic rats. Elevation in the concentrations of malondialdehyde, conjugated dienes, lipid hydroperoxides, protein carbonyl, and fragmented DNA was significantly (P<0.05) lowered by Blighia sapida leaves extract. CONCLUSION: Overall, methanolic extract of Blighia sapida leaves at all doses used reduced blood glucose level and prevented oxidative stress and dyslipidemia in alloxan-induced diabetic rats.

[Ab] Resumo:BACKGROUND: The ripening of fruits is characterized by physical, chemical and biochemical compositional changes such as color, sugars and phenolic compounds. Ackee fruit is famous in Jamaica and the Caribbean. This study aimed to assess the variation of fatty acids in two varieties (cheese and butter) ackee (Blighia sapida) fruits during five different ripening stages. RESULTS: The total fatty acid content of ackee fruit was much higher in arils and ranged from 283.4 to 465.1 g kg(-1) dry weight (DW), while in husk they ranged from 235.2 to 465.1 g kg(-1) DW in both varieties. Total fatty acid content declined in the arils and the husks as the fruit ripened. Five major fatty acids were found: palmitic acid (C16:0) and stearic acid (C18:0), oleic acid (C18:1), linoleic acid (C18:2) and linolenic acid (C18:3). In the arils, oleic acid was found at the highest concentration, followed by palmitic, stearic, linoleic and last linolenic acid. The unsaturated:saturated ratio of fatty acids varied from 1.23 to 3.26 in the arils of both varieties, and from 1.03 to 5.05 in the husk. Monounsaturated:polyunsaturated fatty acids ranged from 8.56 to 25.19 in the arils and from 0.62 to 2.33 in the husk. CONCLUSION: The results show that ackee arils contain much higher levels of fats than the husk and the major fatty acid in the arils was oleic acid (Δ9-cis-oleic acid, an omega n-9), while in the husk unsaturated fatty acids were higher than the saturated ones. Oleic acid was the major fatty acid in both varieties, and aril fatty acid content was 10-20 times higher than in the husk. In both varieties, unsaturated fatty acids were relatively higher than saturated ones; however, total fatty acids showed a decline with ripening for arils and husk tissues.

[Ab] Resumo:The structures of three complex saponins from the fruit pods of Blighia sapida have been elucidated and their (1)H and (13)C NMR spectra assigned employing a variety of one- and two-dimensional NMR techniques without degradative chemistry. The saponins have either four or six monosaccharide units linked to a triterpene aglycone. High-resolution, proton-coupled-HSQC spectra were important for determining both the identities of the intact monosaccharide units and coupling constants in strongly coupled proton spin systems. These NMR experiments will prove crucial as the complexity of saponin structures reaches the limit that can be determined solely by NMR.

[Ti] Título:Tracking hypoglycins A and B over different maturity stages: implications for detoxification of ackee (Blighia sapida K.D. Koenig) fruits.

[Ab] Resumo:Consumption of improperly ripened ackee ( Blighia sapida K.D. Koenig) often results in fatalities. The causal toxin, hypoglycin A, decreases in the edible arilli upon maturity; regulation of hypoglycin A in the arilli is thus critical. Hypoglycin B, also toxic, is confined to the seeds. Hypoglycins A and B were tracked in ackees grown in Jamaica over different maturity stages using RP-HPLC. Studies on the 'Butter' and 'Cheese' ackee varieties and across two different harvest seasons were conducted. In 'Cheese' ackees, hypoglycin A decreased from about 8000 mg/kg in the green arilli and seeds to 271 and 1451 mg/kg, respectively, in the ripe fruit whereas hypoglycin B levels in the seeds increased from 1629 to 11774 mg/kg. The strong inverse relationship demonstrated that hypoglycin B in the seeds serves as a sink for hypoglycin A from the ripening arilli and is thereby involved in the detoxification mechanism of the fruit.

[Ab] Resumo:Between 1998 and 2001 the deaths of 16 Surinamese children were recorded along the Maroni River, which forms the border between Suriname and French Guyana. After a metabolic origin was eliminated, ethnobotanical research in the field led to a hypothesis of intoxication through the ingestion of ackee. Ackee (Blighia sapida) is a large green leafy tree of West African origin. Its unripe fruit contains large quantities of two toxic molecules: hypoglycin-A and hypoglycin-B, the former being the more toxic. We have developed a GC-MS procedure allowing us to demonstrate the presence of hypoglycin-A in the gastric fluid of one of the deceased children, and to compare the content of hypoglycin-A in fruit collected on the road to Paramaribo in Suriname (5.1mg/g) with samples from Burkina Faso (8.1mg/g) and Jamaica (9.2mg/g). Field research showed the misuse of this little-known plant by Maroon witch doctors. The Bushinengue witch doctors were informed about the dangers of ackee, and no new cases have been reported to date.

[Ti] Título:Uses, traditional management, perception of variation and preferences in ackee (Blighia sapida K.D. Koenig) fruit traits in Benin: implications for domestication and conservation.

[Ab] Resumo:BACKGROUND: Blighia sapida is a woody perennial multipurpose fruit tree species native to the Guinean forests of West Africa. The fleshy arils of the ripened fruits are edible. Seeds and capsules of the fruits are used for soap-making and all parts of the tree have medicinal properties. Although so far overlooked by researchers in the region, the tree is highly valued by farmers and is an important component of traditional agroforestry systems in Benin. Fresh arils, dried arils and soap are traded in local and regional markets in Benin providing substantial revenues for farmers, especially women. Recently, ackee has emerged as high-priority species for domestication in Benin but information necessary to elaborate a clear domestication strategy is still very sketchy. This study addresses farmers' indigenous knowledge on uses, management and perception of variation of the species among different ethnic groups taking into account also gender differences. METHODS: 240 randomly selected persons (50% women) belonging to five different ethnic groups, 5 women active in the processing of ackee fruits and 6 traditional healers were surveyed with semi-structured interviews. Information collected refer mainly to the motivation of the respondents to conserve ackee trees in their land, the local uses, the perception of variation, the preference in fruits traits, the management practices to improve the production and regenerate ackee. RESULTS: People have different interests on using ackee, variable knowledge on uses and management practices, and have reported nine differentiation criteria mainly related to the fruits. Ackee phenotypes with preferred fruit traits are perceived by local people to be more abundant in managed in-situ and cultivated stands than in unmanaged wild stands, suggesting that traditional management has initiated a domestication process. As many as 22 diseases have been reported to be healed with ackee. In general, indigenous knowledge about ackee varies among ethnic and gender groups. CONCLUSIONS: With the variation observed among ethnic groups and gender groups for indigenous knowledge and preference in fruits traits, a multiple breeding sampling strategy is recommended during germplasm collection and multiplication. This approach will promote sustainable use and conservation of ackee genetic resources.
