Abstract : Influence of the Preparation "Nicavet-1000" on a Morphofunctional Condition of some Organs of Rats at Experimental Aluminium Intoxication
|
|
Abstract: During the conducted research, it is established that aluminium chloride intoxication leads to the considerable changes of composition of red blood, development of a hypercalcemia and change of a bone structure of animals. A number of significant morphofunctional changes in the hippocampus of the examined animals are also noted. The use of the tissue preparation "Nicavet-1000" leads to the normalization of both hematocrit and other parameters of red blood, as well as to the intensification of erythropoiesis. Use of the preparation "Nicavet-1000", judging from the results of research, prevents pathological changes in a bone tissue, caused by aluminium chloride. "Nicavet-1000" leads to the expressed normalization of both the morphological, and micromorphometric parameters characterizing a hippocampus of rats. Keywords: Aluminium, intoxication, hippocampus, bone tissue, tissue preparation. |
Abstract : Carotenoid Content and Composition in 20 Medicinal Plant Species of Traditional Malay Midwifery Postnatal Bath
|
|
Abstract: Today in Malay community, midwifery traditional knowledge of herbal medicine has disappeared and extinct. The facts are Malay midwives are becoming rare and the more crucial is medicinal plants are over-harvested. The aim of this research is to identify and investigate the active pharmaceutical ingredients content in 20 selected species used in the Malay traditional bath. There is a solid need to analyse the potential of these natural bioactive compounds, particularly carotenoids to be fully utilised and commercialised especially in halal market and health advantages. Through High performance liquid chromatography (HPLC) analysis, all 20 species were found to have at least four individual carotenoid pigments with a relatively high concentration of lutein and β-carotene and lower concentrations of zeaxanthin. Strobilanthes crispus (Pecah Kaca) leaf was detected to have the highest total carotenoid content (1546.80±283.45 μg/g DW)while Psidium guajava (Jambu Batu) shoot has the lowest total carotenoid content (112.9±82.2 μg/g DW). The significant outcome of the research was a new findings of new natural bioactive compound sources as health promoting agents which covers not only the Shariah requirement, but also safety aspects. Moreover, it will preserve the traditional knowledge of Malay traditional bath practices.. Keywords: Malay midwifery, postnatal traditional bath, carotenoids, antioxidant, active pharmaceutical ingredients, natural bioactive compounds. |
Abstract : Natural Carotenoid Pigments of 6 Chlorophyta Freshwater Green Algae Species
|
|
Abstract: Nowadays, halal products are gaining wider recognition as a new benchmark for safety and quality assurance. As a consequence the commercial development of microalgae is established due to their high value chemicals, for examples, β-carotene, astaxanthin, phycobilin pigments and algal extracts for cosmaceutical products. Therefore, many researchers have gained interest to study the potential of microalgae as new valuable chemicals and other product sources. The aim of the research is to explore new sources of pigments to be used as halal food colorants. This quest is not only directed in finding natural alternatives for synthetic dyes, but also to discover new taxons for the carotenoid production. Thus, there is a solid need to investigate the potential of natural pigments, particularly carotenoids in microalgae to be fully utilised and commercialised especially in halal market, health advantages, food products and dye technology. A total of 6 species was evaluated for quantitative and qualitative carotenoid composition, namely, Chlorella fusca, Chlorella vulgaris, Selenastrum capricornutum, Pandorina morum, Botryococcus sudeticus and Chlorococcum sp. The main carotenoids identified in all species through HPLC analysis were lutein, β-cryptoxanthin and β-carotene. The ratio of these carotenoids varies between species. Lutein was detected substantially higher in Chlorella fusca (69.54±11.29 µg/g DW); β-cryptoxanthin in Pandorina morum species (1.24±0.33 µg/g DW) whereas β-carotene in Chlorella vulgaris (18.42±9.2 ug/g DW). The significant outcome of the research will be new findings of new natural carotenoid pigment sources as potential food colorants and bioactive compounds which can be beneficial to halal health promoting products industry. Keywords: Active pharmaceutical ingredients, natural colorants, carotenoid, freshwater green microalgae, lutein, β-carotene, β-cryptoxanthin. |
Abstract : Structural Changes to Immune Organs in Rats after Intermittent Fasting Following a High Carb and Fat Diet
|
|
Abstract: Methods: An experimental study with post-test only control group design, with 15 male rat subjects aged 2.5 months were divided into three groups: first group had a diet that was ad libitum (AL); second group were given a diet high in fats and carbohydrates for 1 month then were fed ad libitum (HCL); and third group were given a diet high in fat and carbohydrates for 1 month continued with alternating 12 hour fasting periods for 72 days (F). Results: Total Hassall’s corpuscles of AL, HCL, and F groups were 1.33 ± 077; 2.58 ± 1.35; and 0.69 ± 0.27, respectively (p = 0.008). Fat cells were not found in the thymus. The largest white pulp in the spleen was found in group F, followed by AL, while the smallest was found in group of HCL (p = 0.01). The most depleted white pulp density was the HCL group. There is no significant difference in the number of leukocytes and different leukocyte count between the groups (p> 0.05). Conclusion: Intermittent fasting for 72 days affects the number of Hassall’s corpuscles in the thymus and the width of white pulp in the spleen of Wistar rats. Keywords: Intermittent fasting, thymus, spleen, leukocytes, high carbohydrate diet, high fat diet. |
