Background
The aim of present study was to demonstrate and compare the hepatoprotective activity of ethanol extract of two well-known plants Swertia chirayita Buch-Ham and Andrographis paniculata (Burm.f.) Nees, in Swiss albino rats.
Method
The hepatotoxicity induced by single dose of CCl4 dissolved in olive oil (1 ml/kg b.w.; p.o.) while vehicle control given food and water only. Vehicle as well as hepatotoxic rats were divided into groups (n = 6). Standard group treated with Silymarin (50 mg/kg b.w.; p.o.) daily for 16 days; and treated group received ethanol extract of plant A. paniculata and S. chirayita at the dose of 200 mg/kg b.w. p.o. daily for 16 days respectively.
Results
Ethanol extract of plant S. chirayita and A. paniculata, at a dose of 200 mg/kg body weight exhibited protective lowering effects of the serum enzyme levels SGPT, SGOT, GGTP and SALP to a significant extent. The pronounced activity observed in ethanol extract of A. Paniculata with dose of 200 mg/kg (b.w.) however decreases the elevated level of bilirubin, and lipid peroxidase (LPO). The decreased level of TP, GSH, SOD and CAT levels in CCl4 induced hepatotoxic animal were significantly increase on treatment with ethanol extract of A. Paniculata and S. chirayita plant. The histopathological studies of liver were also supported hepatoprotective activity of A. paniculata.
Conclusion
Since results of biochemical studies conclude that the ethanol extract of A. Paniculata showed significant better hepatoprotective as compare to S. chirayita.

Objective
The objective of the study is to evaluate the immunomodulatory effect of methanolic leaf extract of Hibiscus tiliaceus (MLHT) in pyrogallol induced immunosuppressed Wistar rats.
Methods
The methanolic extract of leaves of H. tiliaceus was administered orally at the dosage levels of 250 mg/kg/day and 500 mg/kg/day b.w in Wistar rats for 28 days. The assessment of immunomodulatory activity, humoral and cellular immunity was studied by hemagglutination antibody (HA) titer, delayed type hypersensitivity (DTH), Neutrophil adhesion test and carbon clearance test. In order to induce immunosuppression in rats pyrogallol (100 mg/kg/day, p.o.) is used and septilin syrup (1ml/100 g/day, p.o.) used as standard as it is immunostimulating agent. Hematological and biochemical were estimated by standard methods.
Results
Oral administration of MLHT showed a significant increase in the production of circulating antibody titer in response to sheep red blood cells (SRBCs). A significant (P < 0.001) increase in both primary and secondary HA titer was observed when compared to control group, whereas in H. tiliaceus showed significant (P < 0.001) increase in HA titer. MLHT significantly (P < 0.001) potentiated the DTH reaction by facilitating the footpad thickness response to SRBCs in sensitized rats. Also MLHT evoked a significant (P < 0.001) increase in percentage neutrophil adhesion to nylon fibers and phagocytic activity. It also enhanced the production of RBC, WBC and hemoglobin. It does not much affect the biochemical parameters.
Conclusion
An oral administration of the MLHT showed immunomodulatory effect in Wistar rats in a dose dependent manner. From the results obtained and reported phytochemical studies H. tiliaceus has a significant effect on both humoral and cellular immunity in experimental animals, this may be attributed to the polyphenols and flavonoid content of the plant extract.

Background
Oxidative stress leads to various pathological conditions including cancer. Antioxidant enzymes such as superoxide dismutase and catalase represent the cell defense mechanism for preventing oxidative damage. Recently many studies have focused on finding natural antioxidants, especially of plant origin for the treatment of oxidative stress associated diseases. The pharmacological and therapeutic properties of plants are attributed to the ability of antioxidants in them to scavenge free radicals.
Objective
In the present study, goat liver was selected as an in vitro model to determine the antioxidant effects of the three flowers (orange, pink and yellow) of Caesalpinia pulcherrima both in the presence and the absence of a standard oxidant (H2O2). The enzymic antioxidants (catalase, peroxidase, superoxide dismutase, glutathione reductase and glutathione S-transferase) and the non-enzymic antioxidants (vitamins A, C, E and reduced glutathione) were analysed.
Results
Treatment with hydrogen peroxide reduced the antioxidant levels in goat liver slices which were improved on co-treatment with the flower extracts, which proved the antioxidant efficacy of the flowers.
Conclusion
Our findings showed that the methanolic extract of the flowers of C. pulcherrima exhibits significant antioxidant activity against H2O2-induced oxidative stress in goat liver model.

Objectives
The present study emphasizes the prolonged effects of an anti-Alzheimer's drug, Galantamine hydrobromide (GHB) on morphometric, behavioural and cholinergic system in mice in the absence of the disease, AD.
Methods
One month old male albino mice, Mus musculus (20 ± 2 g) were selected as experimental model and GHB as the test drug. The ED50 dose (5 mg/kg body weight) was given to experimental mice once in a day up to 180 days continuously.
Results
Observations on the morphometric aspects such as weight, size and also changes in the behaviour pattern of both control and experimental mice were recorded with help of the Morris water maze technique. Various constituents of the cholinergic system viz. acetylcholine content and acetylcholinesterase level were estimated in different regions of brain such as Olfactory Lobe, Hippocampus, Cerebral Cortex, Cerebellum, Pons-medulla and Spinal cord on selected days during the entire treatment schedule lasting for 180 days through standard biochemical assay techniques. From the results, it was evident that GHB exerted severe perturbations in the cholinergic system in all regions of brain on chronic exposure, thus eventually leading to behavioural changes.
Conclusions
From this, it was concluded that GHB, even though exerted positive effects on all the above mentioned parameters which were of course short-lived and during later stages, GHB exerted ill effects. In view of this, particularly, children are cautioned not to consume indiscriminately any kind of memory enhancing drugs or any formulated health drinks containing these chemicals either directly or indirectly for improvement of their cognitive skills.

Tyrosinase is an important enzyme linked with disorders like Parkinson's, melanogenesis, and hyper pigmentation, and studies on selection tyrosinase inhibitor and its implication in drug therapy is an urgent need. We have investigated five drugs which showcased tyrosinase inhibitor activity when tested by QSAR analysis in AutoDock. Docking study was done with the tyrosinase of B. megaterium, and results highlighted potent binding affinity of the drugs with binding energy in the range of −06.00 kcal/mol. In view, designed drugs show potential as tyrosinase inhibitor and may be used further for study.
Conclusion
All five drugs docked successfully with binding energy in the range of −06.00 kcal/mol suggested significant results.

To develop a stability-indicating reversed phase ultra performance liquid chromatographic (RP-UPLC) method for the determination of related substances in Metoclopramide bulk drugs and pharmaceutical dosage form.
Method
The chromatographic separation was achieved using a Waters X-terra RP18 (150 × 4.6 mm), 3.5 μm particle size column using the gradient program with mobile phase consisting of solvent A: 30 mM monobasic sodium phosphate and 2.3 mM of pentane-1-sulphonic acid sodium salt (pH 3.0 buffer) and solvent-B (Acetonitrile). A flow rate of 1.2 mL/min and UV detector at 273 nm was used. The runtime was 18 min within which Metoclopramide and its four impurities, ACETYLMETO, ACMA, CLEE and ACME were well separated.
Results and discussion
The drug was subjected to stress conditions such as oxidative, acid & base hydrolysis, thermal and photolytic degradation. Metoclopramide was found to degrade significantly in photolytic, oxidative & thermal stress conditions and stable in acid, base, hydrolytic & humidity stress conditions. The major degradation impurities in oxidation and photolytic degradation were identified by LCMS. The degradation products were well resolved from the main peak and its impurities, thus proved the stability-indicating power of the method.
Conclusion
The developed method was validated as per ICH guidelines with respect to specificity, linearity, limit of detection, limit of quantification, accuracy, precision and robustness. The calibration curves obtained for the four impurities were linear over the range 0.062–3.040 μg/mL.

Aim
Listeria monocytogenes acts as a pathogen for humans and animals, mainly causing, neonatal sepsis, abortions in pregnant females and severe infections such as septicemia and meningoencephalitis in susceptible hosts. Current study was aimed to identify novel strains of L. monocytogenes from retail chicken, beef meat and seafood samples.
Methods
In order to identify the strain, extraction and amplification of genomic DNA, 16S rRNA sequence analysis was carried out. Phylogenetic trees were constructed using dnapars and dnaml available in Phylip. The secondary structures of 16S rRNA gene sequence were predicted using UNAFOLD, a Linux based software.
Results
The results obtained were found to be a novel foodborne pathogens, which was further named L. monocytogenes strain Pyde1 and L. monocytogenes strain Pyde2, after characterization the sequence of isolate was deposited in GenBank with accession numbers ‘KC852899’ and ‘KC852900’ respectively. The Gibb's free energy of the secondary structures of L. monocytogenes strain Pyde1 and Pyde2 were −275.60 and −282.20 kcal/mol seems to be more stable in the present investigation.
Conclusion
The described results of phylogenetic distinctiveness and phenotypic disparities indicate that strain 2b represents a novel strain of foodborne pathogens within L. monocytogenes species, for which the name L. monocytogenes strain Pyde1 and L. monocytogenes strain Pyde2 is proposed.
