Background:
The plant
Albizia
amara
(Roxb.) Boiv. bark was used in traditional medical practices of India to treat cardiovascular diseases. Hyperlipidemia is the greatest risk factor of coronary heart disease.
Objective:
The objective of this study was to screen the potential of
A.
amara
against the condition of hyperlipidemia in rats.
Materials
and
Methods:
The antihyperlipidemic activity of
A.
amara
ethanolic extract (AAEE) was studied on Triton X-100 induced model of hyperlipidemia in rats. Hyperlipidemia in experimental rats was evidenced by an enhancement in the levels of serum cholesterol, triglycerides (TGs), low density lipoprotein (LDL), very LDL (VLDL) and decrease in high density lipoprotein (HDL).
Results:
AAEE showed significant antihyperlipidemic effect by lowering the serum levels of biochemical parameters such as a significant reduction in the level of serum cholesterol, TG (104.1 ± 3.39), LDL (48.2 ± 2.19), VLDL (20.81 ± 0.67) and increase in HDL (47.25 ± 2.05) level with an increase in a dose of AAEE (41.39 ± 1.24) < (47.25 ± 2.05), which was similar to the standard drug atorvastatin. The results of serum glutamate oxaloacetate transaminase and serum glutamate pyruvate transaminase also revealed that the plant extract was found to be safe on liver. Histopathological evaluation also revealed the positive effect of the plant extract. Preliminary phytochemical analysis revealed the presence of phytoconstituents such as saponins, glycosides and tannins. The preliminary chemical constituents stood as a strong evidence for the study.
Conclusion:
Summing up the evidences of the pragmatic study, we can conclude that the extract of
A.
amara
(Roxb.) Boiv. Bark aids in declining the condition of hyperlipidemia in rats.

PMID
:25276062
Aim:
The aim was to investigate the antiallergic effect of an aqueous leaf extract of
Pistia
stratiotes
(ALPS) in a murine model of ovalbumin (OVA)-induced allergic conjunctivitis (AC).
Materials and Methods:
Prior to topical challenge (instillation of 1.5 mg OVA in 10 μL phosphate buffered saline into their conjunctival sacs) to induce AC, groups of sensitized Imprinting Control Region mice (injected IP, on day 1 and 7, with 0.2 ml solution of 100 μg OVA and 0.01 mg aluminum hydroxide in phosphate buffered saline), were treated with 5 mg/kg cetirizine, 10, 50 or 100 mg/kg of ALPS, or 2 ml/kg normal saline
per
os
. Conjunctival redness, lid edema, tearing and lid scratching (clinical symptoms of AC) were scored. Serum OVA specific immunoglobulins were determined using ELISA. Histopathological assessment of the conjunctival mucosal tissue was conducted. The extract was screened for secondary plant metabolites.
Results:
Pretreatment with the extract significantly (
P
≤ 0.05-0.01) and dose-dependently reduced the scores for clinical symptoms, which were marked in vehicle-pretreated mice. Pretreatment also lowered (
P
≤ 0.01-0.001) serum OVA specific immunoglobulins. Mast cell infiltration and degranulation in conjunctival stroma (measured by an inflammatory score) in histopathological studies was also significantly low (
P
≤ 0.05-0.01) on pretreatment.
Conclusion:
The ALPS exhibited interesting antiallergic activity and hence could be useful in managing AC.

PMID
:25276064
Background:
Oxidative stress plays a major role in the pathogenesis of chronic fatigue syndrome (CFS). Keeping in view the proven antioxidant activity of
Triticum aestivum
L
.
, this study has been undertaken to explore the potential therapeutic benefit of this plant in the treatment of CFS.
Objective:
To study the protective effect of the ethanolic extract of the leaves of
Triticum aestivum
(EETA) in an experimental mice model of CFS.
Materials and Methods:
Five groups of albino mice (20-25 g) were selected for the study, with five animals in each group. Group A served as the naïve control and Group B served as the stressed control. Groups C and D received EETA (100 mg/kg and 200 mg/kg b.w.). Group E received imipramine (20 mg/kg b.w.). Except for Group A, mice in each group were forced to swim 6 min each for 7 days to induce a state of chronic fatigue. Duration of immobility was measured on every alternate day. After 7 days, various behavioral tests (mirror chamber and elevated plus maize test for anxiety, open field test for locomotor activity) and biochemical estimations (malondialdehyde [MDA] and catalase activity) in mice brain were performed.
Results:
Forced swimming in the stressed group resulted in a significant increase in immobility period, decrease in locomotor activity and elevated anxiety level. The brain homogenate showed significantly increased MDA and decreased catalase levels. The extract-treated groups showed significantly (
P
< 0.05) improved locomotor activity, decreased anxiety level, elevated catalase levels and reduction of MDA.
Conclusion:
The study confirms the protective effects of EETA in CFS.

Effects of L-citrulline diet on stress-induced cold hypersensitivity in mice
p. 297
Yoshinori Kobayashi, Kazuki Narita, Kotaro Chiba, Hiroaki Takemoto, Masahiko Morita, Koji Morishita
DOI
:10.4103/0974-8490.138269
PMID
:25276066
Background:
L-citrulline is an amino acid discovered in watermelon (
Citrullus lanatus
,
Cucurbitaceae
) and is a known component of the nitric oxide (NO) cycle that plays an important role in adjusting blood circulation and supplying NO and a key component of the endothelium-derived relaxing factor.
Objective:
The objective of this study is to evaluate the effect of L-citrulline on a newly established stress-induced cold hypersensitivity mouse model.
Materials and Methods:
When normal mice were forced to swim in water at 25°C for 15 min, their core body temperature dropped to 28.9°C, and then quickly recovered to normal temperature after the mice were transferred to a dry cage at room temperature (25°C). A 1-h immobilization before swimming caused the core body temperature to drop to ca. 24.1°C (4.8°C lower than normal mice), and the speed of core body temperature recovery dropped to 57% of the normal control. We considered this delay in recovery from hypothermia to be a sign of stress-induced cold hypersensitivity. Similar cold hypersensitivity was induced by administration of 50 mM L-NG-nitroarginine methyl ester, a NO synthesis inhibitor.
Results:
In this study, we showed that recovery speed from the stress-induced hypothermia remarkably improved in mice fed a 1% L-citrulline-containing diet for 20 days. Furthermore, the nonfasting blood level of L-arginine and L-citrulline increased significantly in the L-citrulline diet group, and higher serum nitrogen oxide levels were observed during recovery from the cold.
Conclusions:
These results suggested that oral L-citrulline supplementation strengthens vascular endothelium function and attenuates stress-induced cold hypersensitivity by improving blood circulation.

DOI
:10.4103/0974-8490.138278
PMID
:25276068
Context and Objectives:
Lead (Pb) toxicity leads to cell damage in many organs of the body. Using different treatment interventions and modes of administration we comparatively examined the protective ability of some medicinal plants on liver Pb accumulation.
Materials and Methods:
Rats were fed on either 7% w/w
Zingiber officinale
, 7% w/w
Allium sativum
, 10% w/w
Lycopersicon esculentum
, 5%, w/w
Garcinia kola
(all in rat chow), while Pb (100 ppm) was given in drinking water. The additives were administered together with (mode 1), a week after exposure to (mode 2) or a week before metal exposure to (mode 3) the metal for a period of 6 weeks. The metal accumulations in the liver were determined using atomic absorption spectrometry and compared using analysis of variance.
Results:
Some additives significantly (
P
< 0.05) reduced, while others enhanced Pb accumulation. Mode 2 yielded the highest mean % protection and mode 3 the lowest, no significant interaction between modes of administration and time of measurement in their relationships to percentage protection, but there was statistically significant (
P
< 0.05) interaction between modes of administration and additive used in their relationships to percentage protection.
Conclusion:
Protective effects of medicinal plants are varied and depend on the nature of lead exposure.

Allium sativum
p. 334
Avinash G Phadatare, Vivek Viswanathan, Alka Mukne
DOI
:10.4103/0974-8490.138288
PMID
:25276072
Background:
Garlic (
Allium sativum
) has been known to exhibit a wide range of pharmacological activities which are attributed mainly to the organosulfur compounds present in it. Allicin and garlic oil, components obtained from garlic, have been explored and found to be biologically active on various fronts. Allicin is known to have major stability issues due to rapid degradation even at low temperatures, whereas garlic oil, being lipophilic, shows poor bioavailability after oral administration.
Objective:
To develop novel strategies for optimum delivery of allicin and garlic oil so as to achieve effective availability in the physiological system.
Materials and Methods:
Garlic cloves were lyophilized to obtain allicin-releasing garlic powder (ARGP). This powder was analyzed spectrophotometrically and was used to formulate buccal tablets. Garlic oil was obtained by hydrodistillation of garlic cloves and analyzed by gas chromatography. Self-nanoemulsifying systems (SNS) containing garlic oil were prepared using suitable surfactants and cosurfactants. The SNS were adsorbed on Aerosil 200 and filled in hard gelatin capsules. Both the formulations were suitably evaluated.
Results:
Buccal tablets containing ARGP showed satisfactory physical parameters as well as
in vitro
drug release, mucoadhesive strength, moisture uptake capacity and drug content. Evaluation of capsules containing SNS of garlic oil also gave satisfactory results. The adsorbed SNS when dispersed in water formed nanoemulsions.
Conclusion:
Buccal tablets as well as capsules containing garlic oil SNS provide promising strategies to overcome the difficulties associated with formulation of allicin and garlic oil.

DOI
:10.4103/0974-8490.138289
PMID
:25276073
Background:
Different therapeutic regimens were used for eradication of
Helicobacter pylori,
based on the cost, effectiveness and patient's compliance. The aim of this study was the evaluation of licorice compared with bismuth in quadruple regimen on eradication of
H. pylori
in patients with peptic ulcer disease (PUD).
Materials
and
Methods:
In a double-blind clinical trial study, 60 patients with PUD and positive rapid urease test were enrolled. The patients were randomly allocated into two equal groups. In first group, licorice, amoxicillin, metronidazole and omeprazole and in the second (control) group, bismuth subsalicylate, amoxicillin, metronidazole and omeprazole were prescribed respectively, and 4 weeks after treatment, in order to evaluate
H. pylori
eradication, urea breath test was done in all patients. The outcome of the study was the preference usage of licorice as an effective medication for
H. pylori
eradication.
Results:
Mean age of the patients in the control and case groups were 40.8 ± 15.5 and 42.2 ± 15.8 years, respectively (
P
= 0.726). Seventeen (56.7%) patients in control group and 16 (53.3%) in the case group were female
(P
= 0.795). Both groups were similar based on frequency of gastric or duodenal ulcer. Response to treatment were seen in 20 (67%) and 17 (57%) patients of case and control groups, respectively (
P
> 0.05).
Conclusion:
Our study showed that licorice is as effective as bismuth in
H. pylori
eradication; therefore, in patients whom bismuth is contraindicated, licorice can be used safely instead.

PMID
:25276074
Background:
Cnidoscolus quercifolius
is a species popularly known as "favela" and "faveleira", and belonging to the Caatinga biome (semi-arid vegetation, Brazil), where is used in folk medicine as an anti-inflammatory.
Objective:
The aim was to evaluate the anti-inflammatory effect of the ethanolic extract from barks (Cqb-EtOH) and leaves (Cql-EtOH) of
C. quercifolius
in mice using experimental models of inflammation.
Materials
and
Methods:
The preliminary phytochemical analysis of the ethanolic extract was performed. The activity was evaluated by paw edema induced by carrageenan and leukocytes migration to the peritoneal cavity induced by carrageenan methods.
Results:
A preliminary analysis of Cqb-EtOH revealed that it contained coumarins, flavonoids, monoterpenes/diterpenes and naphthoquinones, while the Cql-EtOH showed positive reaction to coumarins, anthracene derivatives, flavonoids, lignans and triterpenes/steroids. Cqb-EtOH and Cql-EtOH (100, 200 and 400 mg/kg) inhibited significantly (
P
< 0.01) the increase in the edema volume after administration of carrageenan. In the peritonitis test, acute pretreatment with Cqb-EtOH and Cql-EtOH (100, 200 and 400 mg/kg) inhibited the leukocyte migration.
Conclusions:
It can be concluded that extracts from the barks and leaves of
C. quercifolius
have anti-inflammatory activity, which supports the popular use of this plant to treat inflammation. Thus, extracts has significant anti-inflammatory properties, which are related probably to inhibition of release of mediators of the inflammatory process.

Background:
The common treatment for cancer is unfavorable because it causes many detrimental side effects, and lately, there has been a growing resistance toward anticancer drugs, which worsens the future of cancer treatment. Therefore, the focus has now shifted toward natural products, such as spices and plants, among many others, to save the future of cancer treatment. Cloves (
Syzygium aromaticum L.
) are spices with the highest antioxidant content among natural products. Besides acting as an antioxidant, cloves also possess many other functions, such as anti-inflammatory, antibacterial, and antiseptic, which makes them an ideal natural source to be developed as an anticancer agent.
Objective:
This study aims to evaluate the cytotoxic activity of cloves toward MCF-7 human breast cancer cell lines.
Materials and Methods:
Different concentrations of water extract, ethanol extract, and essential oil of cloves were investigated for their anticancer potential
in vitro
through a brine shrimp lethality test (BSLT) and an MTT assay.
Results:
In both BSLT and MTT assays, the essential oil showed the highest cytotoxic effect, followed by ethanol and water extract. The LD
50
concentration of essential oil in the 24 hours BSLT was 37 μg/mL. Furthermore, the IC
50
values in the 24 hours and 48 hours MTT assays of the essential oil were 36.43 μg/mL and 17.6 μg/mL, respectively.
Conclusion:
Cloves are natural products with excellent cytotoxicity toward MCF-7 cells; thus, they are promising sources for the development of anticancer agents.
