It is assumed to have various health benefits. However, the synergistic mixture of the content has not been studied scientifically, hence the need to evaluate its effect on the liver and kidney being part of the body’s metabolic organs. Aim: This study evaluated the synergistic mixture of Cyperus esculentus, Phoenix dactylifera and Cocos nucifera (STCD) aqueous extract in male albino rats. Methods: Acute toxicity LD<sub>50</sub> of STCD was carried out, afterwards, fifteen male albino rats were grouped into three groups with 5 rats in each group;Control, 200 mg/kg, 400 mg/kg STCD. The rats were administered STCD orally 24 hourly, for 21 days, with feed and water ad libitum. At the end of the experiment, blood samples were collected for biochemical analysis of the liver and kidney biomarkers, while the liver and kidney tissues were harvested for histopathological examination using standard laboratory methods. Descriptive statistics were computed and expressed as Mean ± SD. One-way ANOVA and Turkeys test was performed. P value ≤0.05 was considered statistically significant. Results: Acute toxicity LD50 of STCD was observed to be ≥2404.2 mg/kg body weight. An increase in the percentage body weight difference of 8.39% and 2.86% was observed for 200 and 400 mg/kg STCD groups. Also, the liver weight was observed to increase in 400 mg/kg (3.92 ± 1.42) in comparison to the control group (3.48 ± 1.61), a decrease in the kidney weight was observed in all groups administered STCD in comparison to the control group. Administration of STCD at both 200 and 400 mg/kg revealed a decrease in the concentration of the hepatic biomarkers AST, ALT, ALP, TP, Albumin, Total and conjugated bilirubin. The kidney biomarker Urea was observed to decrease in concentration for 200 mg/kg STCD (4.60 ± 1.83) and 400 mg/kg STCD (4.76 ± 0.74) when compared to the control group (6.32 ± 2.74). A decrease in Creatinine was observed in 200 mg/kg (91.80 ± 34.69) and 400 mg/kg (98.60 ± 15.53) in comparison to the control group (117.60 ± 42.88). The histological examination of the liver of rats administered STCD revealed structural normal central vein, hepatocytes and portal tract. The kidney examination revealed normal glomeruli and normal tubule. Conclusion: The findings of this study opine that STCD improved the health of both the liver and kidney as evidenced via the biomarkers and histological examinations of the liver and kidney. This study therefore recommends the intake of STCD at moderate doses for improved liver and kidney function due to its bioactive compounds and nutritional content.展开更多

The results show that net suspended sediment is mainly transported by average current, Stokes drift, and gravitational circulation. The transport direction of suspended sediment is varying and basically following the direction of residual tidal currents. Surface sediment transport pathways are primarily parallel to the coastline along with two convergent centers. Waves and longshore currents have a significant influence on sediment transport, but the influence is limited due to a steep and deep underwater bank. Tidal current is the main controlling factor for sediment transport, especially in the deep water area. Neither suspended nor surface sediment is transported towards the southwest. The South Shandong Coastal Current(SSCC) has little effect on sediment transport processes in the nearshore area of Phoenix Island.展开更多

Methods: Three different cultivars of dates(Ajwa, Khalas, and Fardh) were examined in-vivo, for blood clotting and wound healing using CD1 mice of both sexes. Study of toxicity to animals was performed accordingly prior to further investigations. The ethanolic extracts were given orally to animals as a constituent in their daily water. Blood samples were obtained from the mice inferior vena cava to carry out the prothrombin time(PT) assay using the manual method and confirmed using a semi-automated machine. The bleeding time(BT) assay was performed using the cutting technique. In the wound healing analysis, a small cut(5-10 mm) in the skin overlying the thigh was conducted in all mice under anesthesia. The diameter of the cut and healing status were measured on a daily basis throughout the time of the experiment using a roller. Results: Ajwa was able to elevate both PT and BT(P<0.05), significantly in a time-dependent manner followed by Khalas date(P<0.05). The results of PT and BT of Fardh date were found to be very close to those of the control group(P<0.05). Despite its activity as an anticoagulant, Khalas date showed a potential property to enhance wound healing in contrast to other dates and the control groups in this study. Conclusions: Omani Khalas date fruit has both antithrombotic as well as wound healing properties. The results open a new gate with these fruits for exploring the potential component(s) that may play an important role in antithrombotic as well as wound healing process.展开更多

Methods: The effect of aqueous extract (140 mg/kg) of Phoenix dactylifera date palm pollen on sexual behavior and determining of dopamine transmission in the nucleus accumbens was studied in male rats using in vivo microdialysis. Results: Releasing of dopamine increased significantly in the nucleus accumbens when a receptive female was introduced behind a screen (p 0.001). During copulation, dopamine increased markedly in control and treated rats. Phoenix dactylifera Date Palm Pollen enhanced the orientation of males towards females by increasing mounting and ano-genital investigatory behavior. Improving of sexual behavior and dopamine release was higher in treated rats in comparison with control (p 0.001). Conclusion: These results indicate a neurochemical basis for interaction between dopaminergic agents and male sexual behavior. Therefore, Phoenix dactylifera Date Palm Pollen seems to act as a dopamine agonist and to cure male infertility. It can be used as an aphrodisiac that leads to further increases in dopamine release.展开更多

One of such botanicals is Phoenix dactylifera in which the pollen grain has been acclaimed to be used as an aphrodisiac. However, the validity has not been scientifically tested. Dopamine is known to facilitate male sexual function. Therefore, the present study was undertaken to evaluate the effect of aqueous extract of Phoenix dactylifera pollen on the sexual behavior of male rats and to measure of serum Estradiol and Testostrone. Also, dopamine transmission in the nucleus accumbence (NAc) was studied in male rats using in vivo microdialysis. Methods and Materials: sixty male rats were randomized into 6 groups (A-F). Group A received 0.2 ml of Normal Saline mixed with Dimethyl Sulphate (DMSO), while groups B-F were injected same volume containing 35 mg/kg, 70 mg/kg, 105 mg/kg, 140 mg/kg and 350 mg/kg of DPP extract, respectively. Sexual behavioral parameters including mounting, intromission and ejaculation frequencies and latencies were recorded in male rats one hour after injection of extract by mating with a receptive female (1:1). The male serum testosterone and estradiol concentrations were also determined. Results: All doses stimulated male sexual behavior. Extract significantly increased mount, ejaculation, intromission frequencies and ejaculation latency in comparison to controlled ones (p 0.001). Mount and intromission latencies significantly reduced (p 0.001). Maximum effect was observed in dose 140 mg/kg. This extract was found to enhance Testestrone, Estradiol and the orientation of males toward female ones by increasing mounting and ano-genital investigatory behavior. Conclusions: Data from this study identified that the aqueous extract of Phoenix dactylifera pollen grain enhanced sexual behaviour in male rats. The improved sexual appetitive behaviour in male rats may be attributed, to the alkaloids, saponins, and or flavonoids since these phytochemicals has engorgement, androgen enhancing. Also, our findings support the traditional use of this plant as acclaimed aphrodisiac and for the treatment of pre-ejaculation and impotency.展开更多

It is such an important component of Chinese culture that we can see a sort of phenomenon called phoenix phenomenon comes into being in Chinese culture, which deserves efforts to elaborate and whose origin is worth probing. As the totem worshipped by the ancient Chu people, phoenix also displays the basic features of Chinese culture: integratedness and inclusiveness.展开更多
