Anemia is the most widespread nutrition problem in the world and has predominance in developing countries like India, particularly in children and women. The magnitude of the anemia has been well-documented in pregnant women and infants, however, there is no data on the prevailing occurrence of anemia in school children. The main objective of this study was to estimate the prevalence of anemia and its correlation to variables such as age, gender and body mass index in school children of Kattangulathur, Tamil Nadu, India. A total of 900 children in the age group of 8-16 years were included in this study. Parental consent was obtained in the written format. Blood was collected by finger prick and the hemoglobin was determined by cyanmethemoglobin method. A preplanned questionnaire was used to collect the health details of the children. The children were grouped according to the age. Prevalence of anemia as per the World Health Organization (WHO) recommended cutoff value of hemoglobin, among these children was 52.88%. The frequency of the prevalence of anemia was significantly higher amongst girls as compared to the boys. Results of the study population reveal that 52.88% were anemic, girls (67.77%) were 32.2% higher than the boys (35.55%) and anemic children were underweight. Therefore our study results suggest that all the school children should be screened periodically and appropriate measures should be taken..

Process advantages and product benefits of interesterification in oils and fats
Mohammad Asif
July-December 2011, 1(2):134-138
DOI:10.4103/2231-0738.84203  
The physical properties of oils and fats depend on their chemical properties, such as unsaturation, saturation, chain length, and distribution of the three hydroxyl groups of glycerol in the fatty acids. These characteristics change by hydrogenation, fractionation, blending, and interesterification (IE), hence improving the spectrum for the application of the oils and fats. IE is a process where the fatty acids have been moved from one triglyceride molecule to another and it does not alter the fatty acids. IE (chemical and enzymatic) is used to deal with the problems of plastic fat products such as granular development, texture breakdown, lumpy appearance, post hardening, consistency, melting point, and rancidity and create oil more suitable for deep frying or making margarine with good taste and low content of saturated fatty acids, etc. Nutritionally, IE contributes in eliminating or reducing trans fatty acids, providing a higher essential fatty acid activity. Trans and hydrogenated fats increase the coronary heart disease risk factors.

DOI:10.4103/2231-0738.84204  
Aim : The present study was designed to investigate the neuroprotective effect of gamma-tocopherol on MPTP induced Parkinsonic mice. Materials and Methods: Oral administration of γ-tocopherol (48 mg/kg BW) in C57BL/6 mice for seven days. Parkinson's disease was induced by four intraperitoneal injections (from 4th to 7th day) of MPTP (30 mg/kg BW). On the end of experiment (8th day), behavioral studies were performed to understand motor skill abnormalities and then animals were sacrificed to procure midbrain and striatum. Subsequently, homogenized and centrifuged to get postmitochondrial supernatant which was used to assay a) Neurochemical -- Dopamine, DOPAC, HVA b) Biochemical -- TBARS, GSH, GPx, SOD, and Catalase. Results: Pretreatment of γ-tocopherol (48 mg/kg BW) significantly attenuated the MPTP induced behavioral (rotarod performance, open field test, narrow beam walk test and hang test), neurochemical, biochemical alterations in mice suggesting their free-radical scavenging potential. Conclusions: Our results demonstrate that γ-tocopherol confers potent neuroprotection against MPTP-induced toxicity of dopaminergic neurons, and may become a potential therapeutic strategy for neurodegenerative disorder such as Parkinson's disease.

Counterfeit herbal medicine
AR Mullaicharam
July-December 2011, 1(2):97-102
DOI:10.4103/2231-0738.84191  
The mass production of fake and substandard medications is growing global problems with deleterious impact on the individuals who ingest them. Estimates of the scale of the global trade in counterfeit medications vary widely. According to the Food and drug administration (FDA), 6%-10% of medicines sold worldwide are counterfeit. The use of herbal remedies, neutraceuticals, and dietary supplements has increased greatly over the past 40 years. Much of the increase in use can be attributed to the common belief that natural ingredients are inherently safer and healthier than synthetic ingredients. Products sold as ''dietary supplements'' are subject to significantly less regulation and are often not required to have safety testing or FDA approval before they enter the market. Without adequate safeguards and quality control mechanisms, there is no assurance that the concentrations of active ingredient are consistent from batch to batch or even that these supplements contain the ingredients they purport to contain. Professional regulation must be open, responsive, and accountable with the emphasis on both the protection of patients and the public rather than being based exclusively on the needs of practitioners. Pharmacists have a responsibility to educate themselves about herbal therapies in order to help patients discern the facts from the fiction, avoid harm, and gain what benefits may be available. Pharmacists must also cope with an environment in which there is relatively little regulation of herbal therapies by FDA.

P Madhumita, N Gupta
July-December 2011, 1(2):194-200
DOI:10.4103/2231-0738.84214  
Objective : To evaluate the clinical and bacteriological spectrum of community-acquired acute bacterial meningitis (ABM) in an adult population at Lok Nayak Hospital, New Delhi, a tertiary care hospital in northern India. Materials and Methods: Cerebrospinal fluid (CSF) samples from 120 clinically suspected cases of pyogenic meningitis were processed for cell counts, differential counts, bacterial stain and culture, antibiotic susceptibility test, and bacterial antigen detection by latex agglutination test (LAT) in CSF, serum and urine. Results : CSF LAT was positive in 56/120 cases of ABM. Streptococcus pneumoniae was the predominant pathogen in 41 of these 120 cases i.e. 34.0% of all cases. Neisseria meningitidis accounted for 24 cases i.e. 20% of all cases. Staphylococcus aureus was isolated in one case. Bacterial cultures were positive in 22 (18.3%) cases only. Conclusions: Evidence for presence of microbial activity could be detected in 44.1% cases by LAT, whereas a direct microbiological confirmation could be documented in only 22 cases i.e. 18.3%. Streptococcus pneumoniae remains the major etiological agent of ABM in our study. Penicillin resistance was detected in 50% of cases among the isolates which came positive by culture. Neisseria meningitidis was detected in 24 cases. But since none were cultured, sensitivity patterns could not be correlated. LAT is a convenient and rapid test to support bacterial etiology in ABM. In remote situations, their use in serum or urine needs to be considered after evaluation in longer studies. Further research should focus on the preventable aspects of ABM, especially pneumococcal and meningococcal vaccines, to potentially protect susceptible groups.

K.A.S. Praveen, Sarfaraz Aslam, TK Dutta
July-December 2011, 1(2):201-203
DOI:10.4103/2231-0738.84215  
The neurological manifestations of hypothyroidism are very unusual to see as initial symptoms and they usually occur late in the course of disease. Muscle hypertrophy is an extremely rare finding in hypothyroid patients. Hypothyroidism presenting as muscle stiffness and muscle pseudo hypertrophy in adults is known as Hoffmann's syndrome. Laboratory investigation in hypothyroid myopathy generally shows increased levels of muscle enzyme. The electrophysiological study may reveal features suggestive of myopathy, neuropathy or mixed pattern. The symptoms and also the serum levels of enzymes return to normal with hormone replacement therapy. We report a case of hypothyroidism with calf muscle hypertrophy and proximal myopathy as the initial symptoms.

Nagarethinam Baskaran, Duraisamy Rajasekaran, Shanmugam Manoharan
July-December 2011, 1(2):167-173
DOI:10.4103/2231-0738.84209  
Aim : Aim of the present study was to evaluate the antigenotoxic effect of coumarin by measuring the frequencies of micronuclei and the degree of DNA damage in the bone marrow cells of hamster treated with 7,12-dimethylbenz(a)anthracene (DMBA). Materials and Methods: Genotoxicity was induced in experimental hamsters by single intraperitoneal injection of DMBA (30 mg/kg b.w.). The frequency of micronucleated polychromatic erythrocytes (MnPCEs) and DNA damage were assessed in the bone marrow cells of experimental hamsters. The status of lipid peroxidation, antioxidants and phase I and II detoxification agents were utilized as biochemical end points to assess the dose-dependent antigenotoxic potential of coumarin in DMBA-induced genotoxicity. Results: Increase in micronuclei frequency was accompanied by increase in tail length, percent of tail DNA, tail movement and olive tail movement in the bone marrow cells of hamsters treated with DMBA alone. A significant increase in the levels of thiobarbituric acid reactive substances, antioxidants and phase I and II detoxification agents were also noticed in hamsters treated with DMBA alone. Oral pretreatment of coumarin at a dose of 100 mg/kg b.w to hamsters treated with DMBA significantly decreased the frequency of MnPCEs and DNA damage in the bone marrow cells. Also, coumarin restored the status of biochemical variables in the plasma and liver of hamsters treated with DMBA. Conclusions: Present study demonstrated the antigenotoxic effect of coumarin in DMBA-induced genotoxicity. The antigenotoxic potential of coumarin is probably due to its antioxidant potential and modulating effect on detoxification cascade during DMBA-induced genotoxicity.

Selvaraju Subash, Perumal Subramanian
July-December 2011, 1(2):174-178
DOI:10.4103/2231-0738.84210  
Introduction : Hyperammonemia is a major contributing factor to neurological abnormalities observed in hepatic encephalopathy and in congenital defects of ammonia detoxification. Ammonia toxicity results in free radical generation that leads to oxidative stress and tissue damage. Morin is a bioflavonoid, a constituent of many herbs and fruits that are used as herbal medicines and also several biological activities. Our aim is to investigate the effect of morin on blood ammonia and plasma urea as well as kidney lipid peroxidation, and the antioxidant status in ammonium chloride-induced hyperammonemic rats. Materials and Methods: Male albino Wistar rats weighing 180 - 200 g were used for the study. Hyperammonemia was induced by interaperitonial injection of ammonium chloride (100 mg / kg body weight). The rats were treated with morin (30 mg / kg body weight) via oral administration. Administration of morin in hyperammonemic rats reduced the levels of ammonia and urea. The antioxidant property of morin was studied by assessing the activities of thiobarbituric acid reactive substances (TBARS), hydroperoxides (HP), conjugated dienes (CD), and antioxidants superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) and reduced glutathione (GSH) in ammonium chloride-treated rats. Results and Conclusions: Kidney oxidative stress was effectively modulated by morin administration. Morin significantly improved the status of kidney antioxidants and decreased the levels of ammonia, urea, TBARS, HP, and CD, as compared to the ammonium chloride-treated group. The study offers evidence for the antihyperammonemic and antioxidant effects of morin against oxidative stress in the kidney, induced by ammonium chloride.

DOI:10.4103/2231-0738.84207  
Aim : To evaluate the changes in the activities of midgut digestive enzymes activities of silkworm fed with mulberry leaves supplemented with Cowpeas (Vigna unguiculata). Materials and Method: Finely powdered Vigna unguiculata was dissolved in distilled water and diluted to 2.5%, 5%, 7.5%, and 10% concentrations. Fresh mulberry leaves (Morus alba L.) were sprayed by each concentration and were fed to silkworms, from third to fifth instar, five feedings/day. Group 1 larvae received mulberry leaves sprayed with distilled water and served as control, group 2 larvae received 2.5% Vigna unguiculata sprayed mulberry leaves, group 3 larvae received 5% Vigna unguiculata sprayed mulberry leaves, group 4 larvae received 7.5% Vigna unguiculata sprayed mulberry leaves and group 5 larvae received 10% Vigna unguiculata sprayed mulberry leaves. Result: Silkworm larvae fed on Morus alba L. (mulberry) leaves enriched with 7.5% concentrations of Vigna unguiculata, significantly gained more pupa weight, silk length and silk weight as compared to those fed on normal MR 2 mulberry leaves. Hence, 7.5% dose was fixed as an effective dose. Further, same study was conducted to find out the changes in the digestive enzymes activities in the midgut occurred in the fourth day of fourth instar larvae. There was a significant increase in the midgut urease, amylase, sucrase, and protease activities. But midgut trehalase activity was significantly decreased. Conclusions: The results suggest that supplementation of Vigna unguiculata with mulberry leaves at a concentration of 7.5% has enhanced the digestion of ingested food which in turn reflects in the quantity of silk produced.

Effect of N-phthaloyl gamma-aminobutyric acid on lipid peroxidation, antioxidants and liver markers in constant light exposed rats
Selvaraju Subash, Perumal Subramanian
July-December 2011, 1(2):163-166
DOI:10.4103/2231-0738.84208  
Introduction & Materials and Methods : The effect of N-Phthaloyl GABA on the levels of circulatory lipid peroxidation products such as TBARS (thiobarbituric acid reactive substances), antioxidants: SOD (superoxide dimutase), CAT (catalase), GSH (reduced glutathione), and GPx (glutathione peroxidase), liver markers such as AST (aspartate transaminase), ALT (alanine transaminase), and ALP (alkaline phosphatase), were studied for its protective effect during constant light (LL) exposure in rats. Results: A significant increase in the levels of circulatory TBARS, AST, ALT, and ALP were found in LL exposed rats. These changes were significantly decreased in N-Phthaloyl GABA and LL-exposed rats. The levels of antioxidants were significantly decreased in LL-exposed rats and administration of GABA normalized these changes. Conclusions: Our results indicated that NPhthaloyl GABA offered protection by influencing the levels of the lipid peroxidation products, antioxidants, and liver markers during LL-exposed stress. This might be due to the antistress, anticonvulsant, antinociceptive, and antiulcer activities of N-Phthaloyl GABA. The exact mechanism remains to be explored and further research is needed.

Introduction : Diabetes mellitus, the life-threatening endocrine disorder, affects 170 million people worldwide every year. Statistical projections about India suggest that 57 million Indians will be affected by diabetes mellitus by the year 2025, making the country with highest number of diabetics in the world. Alloxan-induced diabetes mellitus in experimental animals is commonly used to evaluate the antidiabetic effect of medicinal plants and their constituents. The present study has investigated the antidiabetic efficacy of ethanolic extract of Coscinium fenestratum stem and Catharanthus roseus leaves in alloxan-induced diabetic rats. Materials and Methods: Diabetes mellitus was induced in overnight fasted (>8 hours) Wistar rats by single intraperitoneal injection of freshly prepared alloxan monohydrate (150 mg/kg bw) solution in physiological saline. The mechanistic pathway for the antidiabetic potential of these plants was evaluated by analyzing the status of glucose, insulin, C-peptide, glycosylated hemoglobin, activities of carbohydrate-metabolizing enzymes, and glycogen content. The antidiabetic effect of these plant products was also compared with the standard reference drug, glibenclamide. Results: The study revealed that the ethanolic extract of C. fenestratum stem and C. roseus leaves have potent antidiabetic efficacy in alloxan-induced diabetic rats. The antidiabetic efficacy was also much comparable with that of glibenclamide. Conclusions: The present study concludes that the ethanolic extract of C. fenestratum stem and C. roseus leaves have potent antihyperglycemic effect in alloxan-induced diabetic rats. C. fenestratum and C. roseus could therefore be used as an alternative remedy for diabetes mellitus and its complications.

Adverse effects of botulinum neurotoxin A in spasticity management
Tapan N Joshi, Sonal Joshi
July-December 2011, 1(2):126-133
DOI:10.4103/2231-0738.84202  
Over the last few decades, Botulinum neurotoxin has evolved from a well-publicized public health threat of food-borne illness, due to contaminated foods, to a widely used therapeutic measure. Botulinum neurotoxin A is one of the seven distinct neurotoxins produced by Clostridium botulinum. The mechanism of action is to block the transmission of overactive nerve impulses to the targeted muscle by selectively preventing the release of the neurotransmitter acetylcholine at the neuromuscular junction. Its efficacy is evident in the treatment of both adults and children with spasticity of various causes. It is considered a safe therapy with most of the adverse events being self-limited and transient. Serious side effects like unwanted muscle weakness and suboptimal response to therapy mainly due to antibody formation are uncommon, but possible. This article gives an in-depth review of the possible adverse effects of botulinum toxin A and their pathogenesis for spasticity management. Physicians should carefully perform a detailed clinical assessment of every patient individually, for a benefit-risk profile, while making treatment decisions, to prevent such adverse events.

Polycystic ovary syndrome (PCOS) is a common and heterogeneous disorder of women of reproductive age, characterized by hyperandrogenism and chronic anovulation. Metformin may lower the androgen level in follicular fluid, affecting local levels of IGF (Insulin like growth factor)s, and may produce improved ovarian stimulation. Metformin is used in PCOS cases in order to decrease plasma luteinizing hormone (LH), hyperinsulinemia, and ovarian androgen levels. Metformin increases the ovulatory rate, cervical scores and pregnancy rate. This review article focuses on the combined effect of metformin administration in PCOS patients.
