Effect of medical herbs in lowering the levels of bilirubin in neonatal blood samples

Seyed Hessamedin Nabavizadeh, Ozair-bin Majid and Amir Anushiravani*

Abstract: Herbal drug therapy is a common practice adopted in traditional and alternative medicine and has been used in the treatment of neonatal jaundice or hyperbilirubinemia from ancient times. This is done with the help of different herbal extracts and using different treatment methods. The knowledge of new possibilities and the fact that herbal drugs have been used in some communities for a long time, clarifies the importance of studying herbal drugs. Herbal drug therapies are used commonly which amplifies the need to evaluate the efficacy of these drugs. This study was performed to evaluate the effect of commonly used herbal drugs in neonatal jaundice, through in vitro techniques. In this study 0.5 cc (50 µg/ml) of different herbal extracts such as Chi corium intybus, Fumaria parviflora, Zizyphus jujuba and Alhagi pseudoalhgi, Purgative manna which were obtained through hydrochloric instillation and were added to 1 cc of neonatal serum with hyperbilirubinemia. Then the level of bilirubin was checked by diazo blank method. Among all of the herbal extracts, only Chi corium intybus demonstrated a lowering effect on indirect serum bilirubin. Although Chi corium intybus showed lower levels than the control group, but statistically there was no significant difference in direct bilirubin levels between these groups. Herbal drugs can decrease the bilirubin level through different mechanisms, such as increasing the activity of liver enzymes and decreasing the enterohepatic circulation. But the extract of the herb Chi corium intybus imposes its affect directly on bilirubin. Therefore further investigation is needed in order to separate the active agent in chi corium intybus.[...] Read More.

G. C. Jain,* Hemant Pareek, B. S. Khajja, Kusum Jain, S. Jhalani, S. Agarwal and Sameer Sharma

Abstract: In the present study, the hepatoprotective activity of methanolic extract of Apium graveolens L. (celery) seeds was tested against Di-(2- ethylhexyl) phthalate (DEHP) induced hepatotoxicity in rats. Oral administration of DEHP (1000 mg/kg b.wt/day) for 6 weeks in rats caused a significant increase in the levels of serum marker enzymes like serum glutamate oxaloacetate transaminase (SGOT), serum glutamate pyruvate transaminase (SGPT), alkaline phosphatases (ALP) and the levels of total bilirubin and hepatic lipid peroxidation (TBARS). The levels of serum protein, hepatic glutathione (GSH) and ascorbic acid were decreased, administration of A. graveolens seeds extract (300 mg/kg b.wt./day p.o.) for 6 weeks results in a significant recovery of these biochemical parameters toward normalcy compared with the DEPC treated and control rats.[...] Read More.

Effect of crocin and curcumin on biochemical alterations associated with iron overload-in-duced liver injury in rats

Shohda A. EL-Maraghy, Sherine M. Rizk and Maha M. El-Sawalhi*

Abstract: The present study was undertaken to evaluate the possible ameliorating effect of crocin and curcumin on certain biochemical alterations associated with iron overload-induced liver injury in rats. 5 groups of rats were used, a normal control group received daily i.p. injections of saline and 4 groups received daily i.p. injections of ferric nitrilotriacetate (FeNTA) for 8 successive days, the dose of iron was increased during the experimental period (from 6 to 15 mg Fe/kg). The first iron overloaded group kept without further treatment and served as a positive control group. The second iron overloaded group received daily i.p injections of crocin (200 mg/kg) in saline. The 3rd and the 4th iron overloaded groups received orally either 0.5% carboxy methyl cellulose (CMC) or curcumin (100 mg/kg) in CMC respectively. Treatment started 3 days before and concurrently with iron administration for 8 days. Results revealed that iron- induced liver injury was reflected by significant changes in the liver function indices, hyperammonemia and reduced serum urea level. A significant deposition of iron in liver was associated with enhanced oxidative and nitrosative stress status. Moreover, iron overloaded rats exhibited significant alterations in liver energy metabolism together with diminished ureogenesis and a decline in dimethylarginine dimethylaminohydrolase activity. Supplementation with either crocin or curcumin ameliorated most of the biochemical changes induced by iron overload in rat liver. A function that may be beneficial for populations at risk for iron overload.[...] Read More.

Annaian Shanmugam, Chendur Palpandi* and Subramanium Sambasivam

Abstract: The fatty acid composition of the wedge clam Donax cuneatus collected from the sandy beach of Cuddalore (southeast coast of India) was determined. In the analysis, the fatty acid profile by gas chromatography revealed the presence of higher amount of saturated fatty acids (35.28%) than mono (12.71%) and polyunsaturated (11.72%) fatty acids. Among the saturated fatty acids, the stearic acid contributed the maximum amount of 15.68%. Whereas the monounsaturated fatty acids (MUFA) were accounted for 26.57% with mostly 16:1w7c (12.71%), fatty acid. Among the PUFA 20:4 w6c (6.75%) and 18:2 w6c (2.41%) acid contents were high. Omega – 6 fatty acids accounted for 10.74% of total PUFA and omega – 3 fatty acids were accounted for 0.48%. Thus the present study enlightens the possible role of this clam in the field of human nutrition.[...] Read More.

Evaluation of biofilm production by Staphylococcus epidermidis isolates from nosocomial infections and skin of healthy volunteers

Fereshteh Eftekhar*and Zeinab Mirmohamadi

Abstract: Staphylococcus epidermidis is a frequent cause of nosocomial infections. The major virulence factor is thought to be biofilm formation by the organism mediated by gene products of the icaADBC operon. In this research, biofilm phenotype and icaADBC gene carriage were studied in 50 S. epidermidis isolates from symptomatic patients (group A) and 50 skin isolates from healthy individuals (group B). Biofilm phenotype was shown by colony morphology on Congo red agar and the microtiter plate method was used for quantitative measurement of biofilm formation. Polymerase chain reaction was employed to detect the presence of icaADBC operon. The results showed no significant difference between the two groups of isolates for the potential to form biofilms by the two phenotypic assays or the amounts of biofilm produced by the two groups of isolates. On the other hand, ica gene carriage was more discriminatory and was observed in 30% of group A isolates compared to 8% of the skin isolates. We conclude that S. epidermidis isolates from patients with symptomatic infections are not necessarily more virulent from the skin contaminants and the capacity to form biofilms in vivo is influenced by environmental stimuli independent of the icaADBC gene products.[...] Read More.

Keywords: Biofilm, Staphylococcus epidermidis, icaADBC, patients isolates, skin isolates.

C. I. Ayolabi*, D. A. Ojo, G. E. Armah, I. Akpan and C. F. Mafiana

Abstract: Norovirus (NoV) has captured increasing attention as an agent of childhood diarrhea, but its incidence in developing countries such as Nigeria has been underreported. This study was conducted to investigate the role of NoVs in sporadic cases of acute diarrhea among hospitalized children. One hundred and eighty-eight (188) specimens comprising 161 diarrheic and 27 non-diarrheic stools were randomly selected from 668 stools previously screened for rotaviruses. These specimens were collected from children under 5 years of age who were hospitalized between November 2007 and May 2008 in Lagos, Nigeria. The specimens were examined for NoV antigen using monoclonal antibody-based enzyme immunoassay (EIA), and the positive specimens were further characterized for norovirus genogroups using reverse transcription-Polymerase chain reactions (RT-PCR) technique. NoV was detected in 60/161 (37.3%) of diarrhoeal and 1(3.7%) of non diarrhoeal children tested. Noroviruses were detected throughout the study period with most patients infected in age group 6 - 12 months. More males were infected with NoV than females however, the difference was not significant (2 = 0.983, p 0.05). Sixteen among the positive samples were amplified by PCR using specific primers, of these, 5 (31%) were typed to be GI, 8 (50%) were GII and three samples (19%) showed a mixed infection of norovirus GI and GII genogroups. This study confirmed the relevance of NoV as a causative agent of pediatric diarrhoea and reported norovirus genogroup GII as the predominant type in circulation in Lagos, Nigeria.[...] Read More.

Delayed diagnosis of ataxia-telangiectasia in an adolescent patient

Ahmet Sert*, Dursun Odabas, Bahar Demir and Cengizhan Kılıcarslan

Abstract: Ataxia-telangiectasia (AT) is a rare autosomal recessive neurodegenerative disorder characterized by cerebellar ataxia, telangiectasies, immune defects, and a predisposition to malignancy. Patients present in early childhood with progressive cerebellar ataxia and later develop conjunctival telangiectases, other progressive neurologic degeneration, sinopulmonary infection and malignancies. Under-diagnosis or diagnostic delay of AT and its pulmonary complications contribute to morbidity and early mortality. We reported a patient who, due to a delay in diagnosis of AT, presented with bronchiectasis at the age of seventeen. To reduce the morbidity associated with AT, there needs to be greater awareness of the respiratory complications. Early management and monitoring lung function can minimize pulmonary damage.[...] Read More.

Cerebrospinal fluid characteristics of PCR diagnosed enteroviral meningitis (EVM) in children

Jaishen Rajah*, Jurgen Sasse, Rula Essam, Tayseer Hassan, Marthinus Pitout Subashnie Devkaran and Afrozul Haq

Abstract: Distinguishing bacterial from viral meningitis helps prevent unnecessary use of antibiotics and decreases the length of stay. The distinction may often be blurred by the typical textbook description of viral meningitis which states that mononuclear cells predominate in the cerebrospinal fluid (CSF). The aim of the work is to accurately describe the CSF response in a group of children with enteroviral meningitis proven by the gold standard, polymerase chain reaction (PCR). A cross sectional study was performed at Sheikh Khalifa Medical City (SKMC), Abu Dhabi, United Arab Emirates (UAE). We examined retrospectively all children (< 12 years as per hospital definition) who tested PCR positive for enterovirus in the CSF from January 2005 to January 2007. 53 patients with mean age (SD) of 74.8 months (37.8) were included. There was a statistically significant dominance in polymorphnuclear cells (PMN) in both the CSF (Chi Square statistic 28.78, P < 0.001) and serum, which persisted after 24 h with mononuclear cells and PMN equally represented. A correlation between CSF and serum PMN% was also detected (Pearson's r = 0.447, P=0.001, 95% CI = 0.196 to 0.643). Our peak season was in spring, there was a male predominance and the median (IQR) length of stay was 48 h (48 -72). The majority of children with aseptic meningitis had PMN predominance in both CSF and serum, which is not limited to the first 24 h. This finding differs from most standard textbook descriptions and may have relevance in using PMN counts to distinguish bacterial from viral meningitis.[...] Read More.

Geohelminthiasis among Nigerian preschool age children

O. P.G. Nmorsi*, C. Isaac, I. S. Aashikpelokhai and N. C. D. Ukwandu

Abstract: A study of the prevalence, intensity and risk factors of geohelminth infections was investigated among preschool children aged 1-5 years old in Ibilo, Akoko-Edo Local Government Area of Edo State, Nigeria. Two hundred and ninety eight children (94.30%) out of 316 volunteers examined were infected with one or more geohelminth parasites. The predominant geohelminth was Ascaris lumbricoides (85.7%, 104.4 epg), followed by hookworm (65.7%, 172.2 epg) and Trichuiris trichuira (2.9%, 305 epg). The difference in the prevalence of infection of the geohelminths among the preschool children was statistically significant (F=6.708, p 0.05). Of the three anthelmintic drugs administered, namely, Albendazole, Mebendazole and Pyrantel pamoate, children treated with Pyrantel pamoate had the lowest parasitic load post treatment and highest cure rate. Places of defecation such as pit latrines, bushes and water closets as well as mothers’/caregivers’ occupation have been identified as potential risk factors contributing to the high infection rates of helminth parasites among preschool age children studied.[...] Read More.

Testicular embryonal rhabdomyosarcoma: A case report

Agabus N. Manasseh, Godwins O. Echejoh*, Olugbenga A. Silas, Matthew N. Tanko, Shola K. Jegede and Barnabas M. Mandong

Abstract: Rhabdomyosarcoma is one of the most frequent soft tissue sarcomas in children. It is found mostly in children, primarily infants, toddlers, and pre-school pupils. However, pure testicular rhabdomyosarcoma is a very rare tumor and few cases have been reported in literature. The tumor usually presents as a painless testicular enlargement with early dissemination via the blood stream and lymphatics. The origin of this tumor is presumed to be from overgrowth of a sarcomatous area of the teratoma. Here, we present a case of testicular rhabdomyosarcoma in a 15-year-old student with a fatal outcome during chemotherapy. This is actually the first case of pure testicular rhabdomyosarcoma diagnosed in this centre after over 10 years.[...] Read More.
