Activation of macrophages with N-formyl-methionyl-leucyl-phenylalanine: Involvement of protein kinase C and tyrosine kinase
Anju Shrivastava
Received 22 February 2007; revised 13 June 2007
N-formyl-methionyl-leucyl-phenylalanine (fMLP)
a potent chemotactic peptide stimulates immune
responses by activating macrophages and other cells of the immune system. The
present study reports inhibition of fMLP-induced
activation of murine peritoneal and P388D-1
macrophage cell line by protein kinase C (PKC)
inhibitors, H-7 and chelerythrine chloride. Similarly, tumoricidal
activity was also downregulated by protein tyrosine kinase (PTK) inhibitors genestein
and lavendustin A. Further, fMLP
increased tyrosine phosphorylation of several
proteins in murine macrophages, which were inhibited
in presence of genestein and lavendustin
A. These findings suggest the involvement of PKC and PTK in the activation of murine macrophages with fMLP.

Effect of chlorophyll and aqueous extracts of Bacopa monniera and Valeriana wallichii on ischaemia and reperfusion-induced cerebral injury in mice
Ashish K Rehni, Hardeep S Pantlya, Richa Shri & Manjeet Singh
Received 27 October 2006; revised 17 May 2007
Bilateral carotid artery occlusion followed
by reperfusion produced significant cerebral infarction and impaired short-term
memory, motor co-ordination and lateral push response. Individual pretreatments with chlorophyll and aqueous extracts of B. monniera and
V. wallichii markedly
attenuated ischaemia-reperfusion induced cerebral
injury in terms of decreased infarct size, increase in short-term memory, motor
in coordination and lateral push response. The results suggest that chlorophyll
and aqueous extracts of B. monniera and V. wallichii prevent ischaemia-reperfusion
induced cerebral injury with comparable potency.

Habib Allah Nemati Karimooy
Received 24 January 2007; revised 26 June 2007
The effects of captopril and Ang II on morphine-induced conditioned place preference (CPP) and morphine self- administration in male Wistar rat were investigated. In CPP experiment, injection of captopril before test significantly decreased the difference of the time spent in compartment A between pre- and post-conditioning compared to morphine group. In self- administration experiment number of active lever pressing was significantly greater than passive in morphine group. In captopril group number of active lever pressing was significantly lower than morphine group however, there was not significant difference between active and passive lever pressed number. The results showed that captopril significantly decreased morphine-induced conditional place preference and morphine self-administration but the effect of Ang II was not significant. It can be concluded that RAS may have a role in rewarding properties of morphine.

Evaluation of in vitro antioxidant activity of Indian bay leaf, Cinnamomum tamala (Buch. -Ham.) T. Nees & Eberm using rat brain synaptosomes as model system
S Lakshmi Devi,
Received 23 January 2007; revised 22 June 2007
The study investigated the perturbation of oxidant-antioxidant balance in brain synaptosomes of diabetic rats and determined the antioxidant and free radical-scavenging property of the Indian bay leaf. Brain synaptosomes were isolated from control and streptozotocin-induced diabetic animals and oxidative stress parameters were assayed. A methanolic extract of bay leaf (BLE) was tested for the polyphenolic content and antioxidant activity by in vitro assays. A significant increase in the levels of lipids and lipid peroxidation products and a decline in antioxidant potential were observed in diabetic rat brain synaptosomes. The total polyphenolic content of BLE was found to be 6.7mg gallic acid equivalents (GAE)/100g. BLE displayed scavenging activity against superoxide and hydroxyl radicals in a concentration-dependent manner. Further, BLE showed inhibition of Fe2+-ascorbate induced lipid peroxidation in both control and diabetic rat brain synaptosomes. Maximum inhibition of lipid peroxidation, radical scavenging action and reducing power of BLE were observed at a concentration of 220 mg GAE. These effects of BLE in vitro were comparable with that of butylated hydroxyl toluene (BHT), a synthetic antioxidant. It can be concluded that synaptosomes from diabetic rats are susceptible to oxidative damage and the positive effects of bay leaf in vitro, could be attributed to the presence of antioxidant phytochemicals. ]

Hypoglycemic and hypolipidemic
effects of alcoholic extract of
Tribulus alatus in streptozotocin-induced diabetic rats: A comparative
study with T. terrestris
(Caltrop)
W H El-Tantawy & L A Hassanin
Received 9 February 2007; revised 15 June 2007
The extracts of both T. alatus and T. terrestris significantly decrease
fasting glucose level in diabetic rats. After 4 and 6 hr, T. alatus extract showed significant
reduction in glucose level as compared to T.
terrestris. After 3 weeks of treatment with T. alatus
extract, glucose level was significantly decreased to the normal level. Both
the extracts also caused a significant decrease in the levels of glycosylated hemoglobin, total
cholesterol, triglycerides and LDL-cholesterol. The percent of reduction in
rats treated with T. alatus
extract was significantly higher than that of the rats treated with
T. terrestris. The results indicate that alcoholic extract of T. alatus possesses hypoglycemic activity
in type-1 model of diabetes.

Antischistosomal and liver protective effects of Curcuma longa extract in Schistosoma mansoni infected mice
Afaf K EL-Ansary, Samia A Ahmed & Sanaa A Aly
Received 9 December 2005; revised
With a view to clarify the induction of the Crabtree consequence in liver cells of S. mansoni infected mice, the curative effect of oil extract of C. longa was tested and compared to praziquantel (PZQ) the effective drug against all schistosome species occurring in man. Protein, glucose, glucose-6-phopsphatase, AMP-deaminase, adensoine deaminase, urea concentration, pyravate kinase (PK), phosphoenol pyruvate carboxykinase (PEPCK) and PK/PEPCK ratio were estimated. In addition, worm burden and ova count in mice infected with S.mansoni were elucidated. The result showed that C. longa normalized the concentration of protein, glucose, AMP-deaminase and adenosine deaminase, which were changed by infection. Moreover, it lowered pyruvate kinase level, while PZQ-treatment induced more elevation of this enzyme. PZQ was more effective in lowering worm burden while C. longa extract was more potent in reducing egg count.

Effects of monosodium
glutamate on food acceptance and toxicity of
selenium in rats
R K Parshad & J K Natt
Received 15 January
2007; revised 12 April 2007
Food acceptance and toxic effects of feeding sodium selenite (Se) alone and in combination with monosodium glutamate (MSG), a taste enhancer were studied in the laboratory rat. Dose-dependent stimulation of daily food intake was observed with MSG offered in no-choice or bi-choice with the plain food. Consumption of pellets containing 0.05, 0.5 and 1.0% Se was significantly low than the plain or MSG containing pellets but their active ingredient was sufficient to cause mortality of rats. Food pellets containing both MSG and Se in no-choice feeding trial were not preferred by the rats, as their consumption remained low as compared to pellets containing only MSG. However, prior feeding on MSG containing pellets for two days increased the amount of intake of Se-containing pellets. No mortality of rats feeding on pellets containing different concentrations of MSG was recorded. Feeding on Se-containing pellets caused dose-dependent mortality on the third day of the trial. As compared to rats feeding on Se-containing pellets, the mortality rate was reduced in those provided Se in combination with MSG but the intake of active ingredient of Se in both these trials did not differ significantly. Decrease in death rate of rats feeding on Se in combination with MSG containing pellets suggested that addition of MSG to seleniferous food probably provide protection to some extent from the toxic effects of selenium. However, combination of excess doses of MSG and Se in food pellets caused mortality of all experimental animals.

In vivo interactive
effect of garlic oil and vitamin E against stavudine
induced genotoxicity in Mus musculus
Pushpindar Kaur & Rattan Singh
Received 4 July 2006; revised 12 April 2007
Stavudine (Zerit, d4T) is widely used as an anti HIV infection drug. It prevents HIV by altering the genetic material of healthy cells but causes mutations in mitochondrial and nuclear DNA. It also produces clastogenic effects in mice. In the present investigation, comet assay test was applied to evaluate the possible genomic damage caused by stavudine and also the ameliorating effects of garlic oil and vitamin E against its genotoxicity in different organs of mice. Two different doses of garlic oil (low and high dose) and vitamin E were administered to mice separately and in combination for six consecutive days followed by a dose of stavudine. The mice were sacrificed after 24, 48 and 72 h of stavudine administration. Both the antioxidants (vitamin E and garlic oil) separately and in combination reduced the genotoxicity of stavudine. The protective effects of high doses of garlic oil were more pronounced as compared to vitamin E administered group.

Non-chemical method of DNA recovery and characterization of Mycobacterium avium subspecies paratuberculosis using IS 900 PCR
S V Singh, P K Singh, A V Singh, J
Received 19 January 2007; revised 25 May 2007
In the present study, two methods of DNA
isolation-routine, traditional and standard DNA isolation protocol for Mycobacteria (Method 1) and a new non-chemicals and
non-enzymes (physical) method (Method 2) of DNA recovery have been compared and
evaluated in IS900 PCR for the specific detection of pathogen. Using the new
Method 2, DNA has been recovered from few (1 3 colonies), extremely minute
and stunted colonies. DNA, thus, isolated from these colonies (colonies PCR)
and cultured for the first time from the cases of Crohns
disease in human beings, dairy cattle, raw milk and pasteurized commercial milk
samples has been characterized in the present study. It is the first report

Pathogenicity, antibiotic susceptibility and genetic similarity of environmental and clinical isolates of Vibrio cholerae
D Immanual Gilwax Prabhu, R Selvaraj Pandian & P Thirumalai Vasan
Received 19 January 2007; revised 17 May 2007
Isolates of Vibrio cholerae were obtained from clinical and environmental samples and the pathogenicity of these isolates was confirmed by hemolytic assay. The clinical isolates were more pathogenic than environmental isolates. Antibiotic susceptibility of V. cholerae to a set of antibiotics showed a marked variation. The environmental isolates exhibited more resistance to the antibiotics than clinical isolates. The plasmid curing technique was used to check the encoding of antibiotic resistance gene in genome. In both isolates, the resistance to vancomycin and co-trimaxazole was not mediated by plasmid and it may probably be encoded in genome. RAPD method was adopted to find out the variation in the genome of the clinical isolates and environmental isolates of V. cholerae. The genomic similarity pattern revealed that the environmental Ogawa isolates were closely related to clinical Ogawa isolates. This study confirmed the existence of the complex nature of V. cholerae in its pathogenicity, response to a set of antibiotics and genetic similarity.

Factors affecting induction and development of in vitro rooting in apple rootstocks
T Sharma, M Modgil & M Thakur
Received 31 August 2007; revised 8 May 2007
Shoots of apple rootstocks raised in vitro were transferred to various rooting media to study the effect of different factors on root initiation and development. Various concentrations of indole-3-butyric acid (IBA) initiated rooting but maximum rooting percentage was found with 2.0 and 2.5 mg l-1 of IBA in M7 and with 1.0 mg l-1 of IBA in MM106. The drawback was that the roots were thick, short and with profuse callus. The presence of activated charcoal (AC) in the rooting medium improved the rooting quality but reduced the rooting percentage in both the rootstocks. In high auxin dip of 70, 80 and 90 mg l-1 IBA for 2, 2 and 1 hr showed 75-85 per cent rooting in M7, but lacked reproducibility of the results. Whereas in MM106, 66 70 % rooting was achieved with 70 mg l-1 of IBA dip for 3 h. Root induction in shoots in IBA containing liquid medium (LM) in dark for few days and root elongation in IBA - free medium in light proved most effective. On the other hand, continuous light treatment showed reduced rooting. Reduction of MS salts and sucrose in root elongation medium showed decreased rooting. Plantlets from two - stage rooting procedure showed more rapid growth and satisfactory survival during hardening of plants and on transfer to field.
