Abstract: Aim of the present study was to investigate the protective effect of genistein and daidzein in combination by analyzing the frequency of micronucleated polychromatic erythrocytes (MnPCEs), chromosomal aberrations and DNA damage in 7,12-dimethylbenz[a]anthracene (DMBA) treated Sprague-Dawley rats. DMBA, a potent site-specific carcinogen, induces mutations in DNA and chromosomal aberrations through its active metabolite, dihydrodiol epoxide. Elevated MnPCEs frequency, marked chromosomal aberrations and increased DNA damage were observed in rats treated with DMBA alone. Oral pretreatment of genistein + daidzein (20mg + 20mg/kg bw, dissolved in 2% DMSO) for 5 days to DMBA treated rats significantly reduced the frequency of MnPCEs and chromosomal abnormalities as well as protected DNA damage. Our results suggest that genistein and daidzein in combination has shown pronounced anticlastogenic and antigenotoxic potential in the bone marrow cells of DMBA treated rats.

Abstract: The optimal fermentation temperature, pH, DO (dissolved oxygen), carbon and nitrogen concentration for production of capsular polysaccharide by Streptococcus pneumonia type-3 in a semi defined medium were determined by using response surface method. The design consisted of 30 experiments. Initial 15 experiments were planned to optimize the fermentation parameters and later 15 were designed to optimize the carbon and nitrogen concentration of the medium. All fermentations were carried in a fermentor with a 2.0L working volume and were terminated after plateau of OD (optical density). The optimum temperature, pH and DO using the semi synthetic medium (Holts medium) yielded an average polysaccharide of 250 mg per liter of culture broth, whereas with the same parameters in the modified Holts medium yielded an average polysaccharide of 400 mg per liter of culture broth. Maximum PS production was observed during exponential phase. Optimal growth parameters like temperature, pH, DO (Dissolved Oxygen Tension), carbon and nitrogen concentration yielded an average of 520 mg of capsular polysaccharide per liter of culture of broth

Key words: Capsular polysaccharide, Streptococcus pneumonia

Abstract: Omnacortil is steroid, an allopathic drug commonly used as analgesic and suppressant in various diseases. In the present work, onion root tips were subjected with a series of omnacortil concentrations, ranging from 0.2 µg/ml, 0.4 µg/ml, 0.6 µg/ml, 0.8 µg/ml and 1.0 µg/ml for 24 hours for studying its effect on root mitosis in Allium cepa L. The roots were examined in permanent root tip squash preparations stained by the aceto-orcein. This work has confirmed that omnacortil have various effects on chromosomes and induced different mitotic abnormalities and structural aberration of chromosomes. Mitotic index (MI), relative division rate (RDR), relative abnormality rate (RAR) of treated material has been determined. Obtained results showed that all the concentrations of omnacortil showed higher MI and RDR, lower concentrations such as 0.2 µg and 0.4 µg showed higher values over rest of the concentrations and control. Among the subjected concentrations 0.8 µg concentration is most effective and showed highest RAR. Low concentrations of steroids act as stimulants while higher concentrations induced various chromosomal aberrations such as clumping and stickiness, fragmentation, C-mitotic effect, anaphase bridge, chromosomal condensation and contraction, dissolution of chromosome, which clearly showed the mutagenic, clastogenic, antimitotic and cytotoxic effect of omnacortil. This is the first report detailing the effects of omnacortil on chromosomes.

Abstract: In present contribution dye decolorizing capacity of Enterobacter species under various influencing physicochemical parameters and metabolic influencing agents  were evaluated.  Study shows that the dye decolourization by this bacterial species was significantly higher in bicarbonate buffers. This may be due to  self anaerobic condition generating buffer, present of citrate, puruvate, α-keto glutarate as all  provide  easily available source of reducing  equivalents  through cellular  metabolism. Dye decolourization in presence of redox mediators such as  riboflavin and reducing agents  like cysteine  shows enhanced  effect, while other  respiratory chain interfering  agents and  reducing equivalents  acceptors ( scavengers) like  quinone, fluoride, sodium azide, NaNO2  KNO3, cystine  and tyrosine  shows  inhibitory action during decolourization. Study reveals optimum conditions necessary  for degradation of azo dyes for fast and complete decolourization to get environmentally safe water.

Department of Biochemistry, Saurshtra University, Rajkot 360 005.  E. mail:

Abstract: Number of studies have claimed that herbal antioxidants are quite useful in heavy metal detoxication and serve as antistressor agents. To verify this view, six well known herbal  (ashwagandha, brahmi, garlic, amla, moringa oil and C-phycocyanin) products, two inherent  antioxidants (glutathione, vitamin E) and one vitamin, associated with general of cell, vitamin B complex, were used to eliminate hexagonal chromium and release the animals from stress. Newly hatched chicks  (Broiler) were divided in to  10 groups (N 9).  All groups were intoxicated with a daily intramuscular injections of potassium dichromate (5 mg/kg body weight) for 7 day. Out of these, group 1 was  kept as such for another 7 days  and sacrificed on 15th day. This was considered as chromium intoxicated group and served as control for rest 9 groups. Group 2 to 10 were treated with different therapeutic agents (ashwagandha, brahmi, garlic, amla, moringa oil and C-phycocyanin), natural antioxidants (glutathione, vitamin E) and vitamin B complex).  Controls were also maintained and the animals were given vehicle only as the case may be. All animals were sacrificed on 15th day and blood was immediately collected and centrifuged at 1500 rpm for 10 min to separate serum and  RBC. The liver, kidney, muscles and brain were also dissected out washed in double distilled cold water, dried with blotting paper and stored in refrigerator until used.  The  chromium content was analyzed using Inductive Coupled Plasma Atomic Emission Spectrometer (ICP) and AAS. Student’s t- test and  ANOVA  were employed to  obtain statistical significance of data. Study shows that antioxidants  application is useful in metal elimination up to some extent as metal enters in all compartments of cell and antioxidant have different power of penetration. On account of this a mixed therapy containing herbal, natural and synthetic antioxidants which can reach all celluar compartments, is recommended.

Abstract: Objective of the present investigation was to estimate the hepatoprotective effect of fruit extracts of Embelia tsjeriam-cottam in paracetamol induced liver damage in Wistar rats. Eight groups of animals were treated with vehicle, 4 plant extract (200 mg/kg, p.o.), N-acetylcystine (100mg/kg, p.o.), and Liv-52 (5ml/kg,p.o.) for seven days. All the animals were challenged with a single dose of paracetamol (2 gm/kg, p.o.) on 5th day. On eighth day serum enzyme estimation were carried out after sacrificing the animals. Liver was preserved for histopathological studies. Further the effects of the extracts on lipid peroxidation (MDA), glutathione (GSH), superoxide dismutase (SOD) and catalase (CAT) were estimated. The only alcoholic and aqueous fruit extracts of Embelia tsjeriam-cottam produced significant hepatoprotective effect by decreasing the activity of serum enzymes, billirubin, MDA and significantly increasing the levels of GSH, SOD and CAT. The alcoholic as well as aqueous extract also showed significant hepatoprotective activity. The efficacy of alcoholic extract was almost comparable to that of N-acetylcystine and Liv-52.

Abstract: Arsenic, a potent environmental oxidative stressor, is associated with the development of diabetes mellitus. The purpose of the study was to investigate the effects of arsenic on the oxidants and antioxidant status of skeletal muscle and epididymal fat pad of male Albino Wistar rats. The rats (135-150g) were administered sodium arsenite at two different doses 1.5mg/kg and 5.0mg/kg body weight or distilled water (control) for 30 days. The induction of diabetes mellitus in arsenic exposed rats was clearly evident from increased blood glucose and glycosylated hemoglobin level. Skeletal muscle and epididymal fat pad of arsenic exposed rats presented significantly higher level of thiobarbituric acid reactive substances (TBARS), advanced oxidation protein product (AOPP), protein carbonyl (PCO) and nitric oxide (NO) than control rats at both doses of arsenic, while the activities of antioxidative enzymes superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) and thioredoxin reductase (TrxR) were declined significantly in both the tissues of arsenic exposed animals compared to control. A significant decline in the level of reduced glutathione (GSH) and increase in myleoperoxidase (MPO) activity were observed in skeletal muscle and epididymal fat pad of arsenic exposed rats as compared to control. The results of the study have shown the arsenic induced oxidative stress in skeletal muscle and epididymal fat pad, which might be associated with impaired glucose homeostasis, leading to arsenic induced diabetes mellitus.

Abstract: Medicinal plants, as source of remedies, are widely used as alternative therapeutic utensil for the anticipation or treatment of many diseases. In present study, we aspire to assess total phenolic and flavonoid content and in vitro antioxidant and metal chelating property of aqueous extract (AE), methanolic extract (ME) and butanolic extract (BE) of mature bamboo leaves by various assays. Study shows that methanol was most effective solvent to extract phenolic (14.6 mg GAE/g powder) and flavonoid (6.71 mM quercetin equivalent/g powder) compounds as compared to water and butanol. The phenolic content  of water  and butanolic extract was 2.79 and 4.26 mg GAE/g powder respectively, whereas, the flavonoid content of aqueous extract was higher ( 6.17 mM quercetin equivalent/g powder ) than butanolic extract ( 2.54 mM quercetin equivalent/g powder). The methanolic extract have shown the highest antiradical scavenging, metal chelating and nitric oxide scavenging capacity as specified by lower IC50 value indicative of higher antioxidative capacity. Ferric reducing antioxidant power was comparatively higher for methanolic extract than the other two solvents used in the study. Over all study indicates that in vitro antioxidative properties of methanolic extract of bamboo leaves was comparatively higher.

College of Pharmaceutical Sciences,ManipalUniversity,Manipal 576 104,Karnataka,

Abstract: Pheromones are low molecular weight chemical substances that are produced by aplant or animal and cause a response in another individual of same or another spices. Pheromones can be of many different chemical types, to serve different functions even for survival of the individual. Pheromones are sending out subconscious scent signals to male or female that naturally trigger attraction, arousal and readiness for sex for propagation of specie. This is perhaps the most vital factor in attraction. These pheromones are detected through the nose and it in turn immediately sends signals to the brain, making the individual subconsciously attracted
to opposite sex.
