Identification And Characterization

Medicinal plants act as a vital source in improving health and overcoming the side effects of modern-day medicine. Many evidence-based reports are present in the literature about the benefits of medicinal plants. Clitoria ternatea L. belongs to the family Fabaceae and is known to be one of the important Ayurvedic medicinal plant whose uses are specified mainly for the modification of nervous system activities. ‘Medhyarasayana’ is one of the Ayurvedic formulations which is used to promote the intellectual capacity, revive the body and nervous tissue, Clitoria ternatea serves as a major constituent of ‘Medhyarasayana.’ Identification and characterization of active metabolites of C. ternatea will help to isolate the important phytoconstituents responsible for the central nervous system effects, isolated components can be utilized in future for the formulation of new medicine for various neurodegenerative disorders. In the present study, the phytochemical evaluation of the ethanolic root extract of C. ternatea (EECT) was performed using the HR-LCMS technique. Preliminary qualitative phytoconstituents analysis showed the presence of tannins, alkaloids, saponins, steroids, carbohydrate, protein, flavonoids and triterpenoids in the ethanolic root extract. Almost 42 compounds were identified when the EECT subjected to HR-LCMS analysis.

The anaesthetic effects of pregnanedione and other related steroids were first described in 1941.1 Hydroxydione was the first drug in this group to be used clinically, but it had serious disadvantages.2 Althesin (Glaxo) is a mixture of two water-insoluble pregnanedione derivatives, alphaxalone and alphadolone, dissolved in Cremophor EL (polyoxyethylated castor oil), for intravenous injection. Alphaxalone is the major constituent; alpha-dolone is less potent and is put in to make alphaxalone more soluble in Cremophor. The solution is viscous, but slightly less so than that of propanidid (Epontol - Bayer), which also contains Cremophor.

Our research work was designed to investigate the curative and preventive effects of Carthamus oxycantha root extract against diarrhea and microorganisms. For the antibacterial experiment, the agar well diffusion method was used against standard bacteria Staphylococcus aureus, Escherichia coli, Pseudomonas aeroginosa, and Salmonella typhi, while for the assessment of antidiarrheal activity, castor oil and the magnesium sulfate-induced diarrhea method was used on albino, laboratory-bred (BALB/c) mice at a dose rate of 200 and 400 mg/kg (body weight, b.w) orally. The methanol extract of C. oxycantha significantly (p < 0.001) decreased the frequency of defecation, and wet stools in a dose depended on the manner of after receiving magnesium sulfate (2 g/kg (b.w)) and castor oil (1.0 mL/mice). Furthermore, the extract of C. oxycantha showed concentration-dependent antimicrobial properties against S. aureus followed by S. typhi, E. coli, and P. aeroginosa bacterial strains, with inhibitions ranging from 10.5–15 mm. These findings show significant results that C. oxycantha is effective as an antidiarrheal and antibacterial agent. However, further works are needed to establish its mode of action.

This study aimed at providing pharmacological rationale for the ethnomedicinal use of Parquetina nigrescens root in the treatment of diarrhoea. The antidiarrhoeal activity of methanol root extract of P. nigrescens(MPN) was determined using castor oil-induced diarrhoea (COD), castor oil-induced enteropooling (COE) and gastrointestinal motility (GIT) tests. In COD, MPN at all doses significantly (p≤0.01) delayed the onset of diarrhoea and significantly (p≤0.05) decreased the number of wet faeces (with percentage inhibition of 52.2; 53.33 and 71.13 at 25, 50 and 100 mg/kg) respectively. The frequency of defecation was significantly (p≤0.01) decreased at 50 and 100 mg/kg. In COE, MPN at all doses significantly (p≤0.01) reduced the volume of intestinal content with percentage inhibition of intestinal fluid accumulation of 79.36; 47.62; 68.25 at doses of 25, 50 and 100 mg/kg respectively against control. In the GIT test, MPN significantly (p≤0.01) decreased the distance travelled by charcoal with a percentage reduction of peristalsis index of 41.19; 47.26; 43.46 at doses of 25, 50 and 100 mg/kg respectively against control. The percentage inhibition of GIT at all doses of MPN was 50.48, 39.00 and 45.62 respectively. MPN possesses antidiarrhoeal activity thus, the credence for its ethnomedicinal use in the treatment of diarrhoea.

Antidiarrheal Activity

Introduction. Diarrheal diseases are associated with an estimated 1.3 million deaths annually, with most occurring in resource-limited countries; up to 25% of deaths in young children living in Africa and southeast Asia are attributable to acute gastroenteritis. Due to limitations associated with various treatments available, the need for developing newer drugs is imperative. Objective. This study was aimed to evaluate the antidiarrheal activity of root extract and fractions of C. abyssinica Jaub. & Spach. (Euphorbiaceae) in mice. Methods. After plant extraction and subsequent fractionation of the crude extract, the antidiarrheal activity was screened in castor oil induced diarrhea, castor oil induced enteropooling, and gastrointestinal motility test models accordingly. Result. The root extract of C. abyssinica produced neither visible signs of toxicity nor death at a single dose of 2000 mg/kg, suggesting the LD50 > 2000 mg/kg. In the castor oil induced diarrheal model, the highest dose of the extract (400 mg/kg) showed a maximal inhibition in the onset (158.00 ± 14.64, p<0.01, in minutes) of wet feces as compared to the negative control. In the enteropooling model, 400 mg/kg treated mice showed a significant reduction in volume (0.47 ± 0.02 ml, p<0.01) and weight (0.50 ± 0.02 g, p<0.05) of intestinal content as compared to the vehicle treated group. In the gastrointestinal motility test, the hydromethanolic root extract of C. abyssinica significantly inhibited the intestinal transit of charcoal meal at 400 mg/kg. In addition, chloroform and n-butanol fractions significantly reduced the distance moved by charcoal at doses of 200 mg/kg and 400 mg/kg, whereas aqueous fraction showed a significant effect at all test doses. The highest antidiarrheal index was observed at the maximal dose of extract and each fraction. Conclusion. The results obtained showed that the findings provide scientific support for the folkloric repute of C. abyssinica roots as treatment of diarrhea.

Kava is a plant root extract that is widely consumed by Pacific Islanders. Kava contains a class of lactone compounds called kavalactones. The sedative and anxiolytic effects of kava are likely attributed to the efficacies of kavalactones on the nervous system. Although some studies have implicated the potencies of certain kavalactone species on γ-aminobutyric acid transmission, evidence supporting the action of kavalactones on the eukaryotic neuromuscular junction (NMJ) and acetylcholine (ACh) transmission is scant. Here, we used behavioral assays to demonstrate the effects of kavalactones at the Caenorhabditis elegans NMJ. Our results suggest that kavalactones disrupt the inhibitory-excitatory balance at the NMJ. Such perturbation of NMJ activity is likely due to excess or prolonged ACh transmission. In addition, we found that kavain, a major constituent of kava, induced worm paralysis but not convulsions. Hence, the modulatory action of kavain could be distinct from the other kavalactone species.

Effect Of Light

Cyanobacteria are Gram negative prokaryotes that are capable of oxygenic photosynthesis. Although there are many similarities between eukaryotes and cyanobacteria in electron transfer and phosphorylation during photosynthesis, there are two features of the photosynthetic apparatus in cyanobacteria which distinguishes them from plants. Cyanobacteria contain phycobiliproteins organized in phycobilisomes on the surface of photosynthetic membrane. Another difference is in the organization of the photosynthetic membranes. Instead of stacked thylakolds within a chloroplast envelope membrane, as seen In eukaryotes, IntracytopIasmlc membranes generally are arranged in three to six concentric layers. Environmental factors such as temperature, nutrition and light fluency can significantly affect the physiology and morphology of cells. The effect of light Intensity shifts on the ultrastructure of Internal membrane in Anabaena variabilis grown under controlled environmental conditions was examined. Since a major constituent of cyanobacterial thylakolds are lipids, the fatty acid content also was measured and correlated with uItrastructural changes. The regulation of fatty acid synthesis in cyanobacteria ultimately can be studied if the fatty acid content can be manipulated.

Jet fuels such as JP-4 can be introduced into the environment and come in contact with aquatic biota in several ways. Studies in this laboratory have demonstrated JP-4 toxicity to fish. Benzene is the major constituent of the water soluble fraction of JP-4. The normal surface morphology of bluegill olfactory lamellae was examined in conjunction with electrophysiology experiments. There was no information regarding the ultrastructural and physiological responses of the olfactory epithelium of bluegills to acute benzene exposure.The purpose of this investigation was to determine the effects of benzene on the surface morphology of the nasal rosettes of the bluegill sunfish (Lepomis macrochirus). Bluegills were exposed to a sublethal concentration of 7.7±0.2ppm (+S.E.M.) benzene for five, ten or fourteen days. Nasal rosettes were fixed in 2.5% glutaraldehyde and 2.0% paraformaldehyde in 0.1M cacodylate buffer (pH 7.4) containing 1.25mM calcium chloride. Specimens were processed for scanning electron microscopy.
