Ethnomedicinal uses of plants for various diseases in the remote areas of Changa Manga Forest, Pakistan / Usos etnomedicinais de plantas para várias doenças nas áreas remotas da Floresta Changa Manga, Paquistão

This study aims at reporting the indigenous knowledge of the medicinal flora from the inhabitants of surroundings of the World's largest artificial planted forest "Changa Manga", Pakistan. Data were collected by direct interviews and group meetings from 81 inhabitants including 32 local healers having information regarding the use of indigenous medicinal plants over a period of one year. Different statistical tools were applied to analyze the data including Frequency citation (FC), Relative frequency citation (RFC), Use Value, Factor of informants consensus and fidelity level. This study reported 73 plant species belonging to 37 plant families and 46 genera. The majority of plant species belong to compositae family. The most commonly used medicinal plants were P. hysterophorus L., P. dactylifera L., S. indicum L, P. harmala L., P. emblica L., and A. indica A.Juss. The greatest number of species was used to cure gastrointestinal disorders. The highest fidelity level (68.18%) was of E. helioscopia to cure gastrointestinal disorders. Maximum fresh uses (17) were reported by C. dactylon (L.) Pars. While the highest number of species reporting fresh uses in similar number was 13. In this study, five novel plants are being reported for the first time in Pakistan for their ethnomedicinal worth. Our data reflect unique usage of the medicinal plants in the study area. The statistical tools used in the study proved useful in pointing the most important and disease category specific plants. High use value plant and the new reported medicinal plants might prove an important source of the isolation of pharmacologically active compounds.

Este estudo tem como objetivo relatar o conhecimento indígena sobre a flora medicinal dos habitantes do entorno da maior floresta artificial plantada do mundo, a Changa Manga, no Paquistão. Os dados foram coletados por meio de entrevistas diretas e reuniões em grupo de 81 habitantes, incluindo 32 curandeiros locais, com informações sobre o uso de plantas medicinais indígenas durante o período de um ano. Diferentes ferramentas estatísticas foram aplicadas para analisar os dados, incluindo citação de frequência (FC), citação de frequência relativa (RFC), valor de uso, fator de consenso dos informantes e nível de fidelidade. Este estudo relatou 73 espécies de plantas pertencentes a 37 famílias de plantas e 46 gêneros. A maioria das espécies de plantas pertence à família Compositae. As plantas medicinais mais utilizadas foram P. hysterophorus L., P. dactylifera L., S. indicum L., P. harmala L., P. emblica L. e A. indica A. Juss. O maior número de espécies foi usado para curar distúrbios gastrointestinais. O maior nível de fidelidade (68,18%) foi de E. helioscopia para cura de distúrbios gastrointestinais. Os usos máximos em fresco (17) foram relatados por C. dactylon (L.) Pars. enquanto o maior número de espécies relatando usos frescos em número semelhante foi de 13. Neste estudo, cinco novas plantas estão sendo relatadas pela primeira vez no Paquistão por seu valor etnomedicinal. Nossos dados refletem o uso exclusivo das plantas medicinais na área de estudo. As ferramentas estatísticas utilizadas no estudo mostraram-se úteis para apontar as plantas mais importantes e específicas da categoria de doença. Plantas de alto valor de uso e as novas plantas medicinais relatadas podem ser uma importante fonte de isolamento de compostos farmacologicamente ativos.

Serum Zinc, Copper, Magnesium & Phosphorus Level in Children with Severe Acute Malnutrition (SAM).

Malnutrition is widely prevalent among hospitalized children in most developing countries including Bangladesh. Though malnutrition accounts for the high rate of under 5 mortality sometimes it is overlooked. Keeping in this in mind A comparative cross sectional study was done in Mymensingh Medical College Hospital from 1st October 2009 to 31st May 2011. Children aged 1-5 years with presence of one or more criteria WHM <70%, WHZ-score <-3SD, Bipedal edema & Mid upper arm circumference <110mm were taken as study group and children aged 1-5 years with normal growth allowable normal range of variation is between 3rd and 97th centile curve or median (50th centile) ±2SD of weight for age growth chart (CDC growth chart, USA, 2000) were taken as reference group. Persistent diarrhea, Patients taking medications containing zinc, copper, magnesium, phosphorus & calcium, PEM with shock were excluded from study group. Nutritional assessment was done according to WHO criteria of SAM. Serum Zinc, Copper Magnesium and Phosphorus level were determined by Atomic Absorption Spectrometry using UNICAM - AA Spectrometer, model no. 969, Spain. Total 120 study populations were taken. Ninety Out of 120 were taken as a study group (SAM) & 30 were reference group. In reference group serum Zn, Cu, Mg, P value was 103.80±8.86µg/dl, 135.92±13.57µg/dl, 2.31±0.18mg/dl, 3.96±0.22mg/dl respectively. In study group serum Zn, Cu, Mg, P value was 60.33±11.08µg/dl, 80.60±15.46µg/dl, 1.47±0.22mg/dl, 2.00±0.52mg/dl respectively. All these results show that there is significant difference between study group & reference group. Considering the decreased level of these parameters, close biochemical monitoring and follow up should be emphasized for the children with SAM.

Efficacy of Peppermint oil in diarrhea predominant IBS - a double blind randomized placebo - controlled study.

Irritable bowel syndrome (IBS) is one of the most common functional gastrointestinal disorder which is associated with considerable sufferings of patient and Peppermint oil is volatile oil, its active principle is menthol-contain a cyclic monoterpine which has anti-spasmotic properties due to its ability to block calcium channel of intestinal smooth muscles. This study observed the efficacy of peppermint oil for relieving the symptoms and changes of quality of life (QOL) in diarrhea predominant IBS. This was a prospective double blind randomized placebo-controlled study conducted in the Bangabandhu Sheikh Mujib Medical University during July 2008 to September 2009. Patients who fulfilled ROME II were initially selected but those had red flag signs or any organic disease was excluded from the study. Seventy four patients were enrolled in the study and randomly allocated to receive either peppermint oil or placebo three times daily for six weeks. Changes of symptoms were assessed three week interval during treatment and two weeks after the end of treatment. Data were analyzed by paired and unpaired 't' test. Finally sixty five patients completed the trial. It was observed that, at six weeks of therapy abdominal pain is markedly improved (mean±SD) 4.94±1.30 in peppermint oil group compared with 6.15±1.24 in placebo group and the difference was statistically highly significant (p>0.001). But two weeks after end of trials pain score again increased (6.09±1.93). Other symptoms and quality of life did not improve significantly. So the study result concludes that peppermint oil is effective in reliving only abdominal pain in diarrhea predominant IBS transiently.
