Drinking water quality of various sources in Peshawar, Mardan, Kohat and Swat districts of Khyber Pakhtunkhwa province, Pakistan

Abstract The present study involves the chemical and bacteriological analysis of water from different sources i.e., bore, wells, bottle, and tap, from Peshawar, Mardan, Swat and Kohat districts of Khyber Pakhtunkhwa (KP) province, Pakistan. From each district, 50 water samples (10 samples from each source), regardless of urban and rural status, were collected from these sources and analysed for sulphates, nitrates, nitrites, chlorides, total soluble solids and coliforms (E. coli). Results indicated that majority of the water sources had unacceptable E. coli count i.e.> 34 CFU/100mL. E. coli positive samples were high in Mardan District, followed by Kohat, Swat and Peshawar district. Besides this, the some water sources were also chemically contaminated by different inorganic fertilizers (nitrates/nitrites of sodium, potassium) but under safe levels whereas agricultural and industrial wastes (chloride and sulphate compounds) were in unsafe range. Among all districts, the water quality was found comparatively more deteriorated in Kohat and Mardan districts than Peshawar and Swat districts. Such chemically and bacteriologically unfit water sources for drinking and can cause human health problems.

Resumo O presente estudo envolve a análise química e bacteriológica de água de diferentes fontes, ou seja, furo, poços, garrafa e torneira, dos distritos de Peshawar, Mardan, Swat e Kohat da província de Khyber Pakhtunkhwa (KP), Paquistão. De cada distrito, 50 amostras de água (10 amostras de cada fonte), independentemente do status urbano e rural, foram coletadas dessas fontes e analisadas para sulfatos, nitratos, nitritos, cloretos, sólidos solúveis totais e coliformes (E. coli). Os resultados indicaram que a maioria das fontes de água tinha uma contagem inaceitável de E. coli, ou seja, > 34 UFC / 100 mL. As amostras positivas para E. coli foram elevadas no distrito de Mardan, seguido por Kohat, Swat e distrito de Peshawar. Além disso, algumas fontes de água também foram contaminadas quimicamente por diferentes fertilizantes inorgânicos (nitratos/nitritos de sódio, potássio), mas em níveis seguros, enquanto os resíduos agrícolas e industriais (compostos de cloreto e sulfato) estavam em níveis inseguros. Entre todos os distritos, a qualidade da água foi considerada comparativamente mais deteriorada nos distritos de Kohat e Mardan do que nos distritos de Peshawar e Swat. Essas fontes de água química e bacteriologicamente impróprias para beber podem causar problemas à saúde humana.

Correlation between Impaired Aortic Distensibility and the Severity of Coronary Artery Disease and Calcium Scoring Measured by Cardiac CT

Background: Multi-Slice cardiac CT has evolved as a noninvasive imaging technique for evaluation of stenosis in the coronary arteries by what is called Coronary Computed Tomographic Angiography (CCTA), but it is also widely used in quantitative plaque assessments through Coronary Artery Calcium (CAC) scoring and plaque type identification ( soft or Mixed VS calcific) . Evaluation of aortic distensibility and aortic stiffness can also be performed through Multi-Slice Computed Tomography (MSCT) by calculating Aortic Distensibility Index (ADI) and Pulse Wave Velocity (PWV). Aim: To evaluate whether impaired Aortic Distensibility Index (ADI) and Aortic Stiffness measured by Cardiac CT is correlating with the severity of coronary artery disease and coronary calcium scoring in at-risk individuals (assessed by CCTA). Patients and Methods: We included 180 patients. Patients were classified into four groups according to their CAC score and according to the degree of stenosis based on CCTA. All patients in this study have underwent full history taking, short clinical examination including B.P. and H.R. measurements, standard ECG, routine laboratory investigations, and Multi-Slice CT Coronary Angiography (MSCT-CA). All patients underwent coronary artery calcium (CAC) scanning and CCTA, and their ADI and Aortic Stiffness were measured. Maximum systolic and maximum diastolic cross sectional-area (CSA) of ascending-aorta (AAo) was measured 15-mm above the left main coronary ostium. ADI was defined as: [(Systolic CSA –Diastolic CSA)/ (Diastolic CSA in X systemic-pulse-pressure) X 103]. Aortic stiffness was measured as PWV using Bramwell-Hill equation [1] [(3.57/ ?distensibility)]. Results: There were strong correlation between Aortic distensibility and Aortic stiffness (PWV) with degree of stenosis and coronary artery calcium. In patients stratified based on the degree of calcium scoring (CAC score), there was a statistically significant negative correlation between calcium scoring and the ADI (Pearson's r= -0.771, p<?.001), and a statistically significant positive correlation between calcium scoring and PWV (Pearson's r=0.817, p<?.001). In patients stratified based on the degree of stenosis, there was a statistically significant negative correlation between ADI and the Degree of stenosis (Pearson's r=-0.707, p<?.001), and there was a statistically significant positive correlation between PWV and the Degree of stenosis (Pearson's r=0.697, p<?.001). Conclusion: Impaired aortic distensibility strongly correlates with the severity of coronary atherosclerosis, degree of stenosis and coronary artery calcium. Addition of ADI to CAC and traditional risk factors provides incremental value to predict at-risk individuals.

Protein and Mineral Contents in Some Fish Species Available in the Brahmaputra River of Bangladesh

An experiment was conducted in the laboratory of the Department of Agricultural Chemistry, Bangladesh Agricultural University (BAU), Mymensingh to determine protein and major mineral nutrients (viz. Ca, Mg, Na, K, P, S and Fe) in different available fish species of the Brahmaputra River of Bangladesh. Total 32 fish samples of 15 fish species were collected from three locations of the river during November 2017. The highest amount of Ca (2.00%), Mg (4.17%), Na (0.41%), K (3.24%), P (0.17%), S (0.129%) and Fe (226.9 mg kg−1) were obtained from chela (Salmophasia bacaila), chanda (Chanda nama), chingri (Macrobrachium sp.), shingi (Heteropneustes fossilis), bele (Glossogobius giuris), baim (Macrognathus aculeatus) and mola (Amblypharyngodon mola), respectively and the sequence of the mineral nutrients was K > Mg > Ca > Na > P > S > Fe. The study results revealed that 100% of daily Ca requirement can be replenished by consuming 100 g fish flesh portion of the chela (Salmophasia bacaila)/ chingri (Macrobrachium sp.)/ bele (Glossogobius giuris). Similarly, among the 15 fish species, 11 and 12 species alone can contribute 100% of Mg and K requirement for human by taking 100 g fish flesh, respectively. The maximum content of N (3.88%) was obtained from shingi (Heteropneustes fossilis), while the minimum (2.81%) was recorded from mola (Amblypharyngodon mola). The protein content among the fish samples varied between 17.6-24.3% with a mean value of 21.2%. Finally, the study results concluded that the common fishes available in the Brahmaputra River are a good source of protein and major mineral nutrients, which contributes in nutrition to the local people of the country.

Perkinsus beihaiensis (Perkinsozoa) in oysters of Bahia State, Brazil / Perkinsus beihaiensis (Perkinsozoa) em ostras do Estado da Bahia

Abstract This study reports the pathogen Perkinsus beihaiensis in oysters of the genus Crassostrea on the coast of the State of Bahia (Brazil), its prevalence, infection intensity and correlation with salinity. Oysters (n = 240) were collected between October and December 2014 at eight sampling stations between latitudes 13°55'S and 15°42'S. The laboratory procedures included macroscopic analysis, histology, culture in Ray's fluid thioglycollate medium (RFTM), Polymerase Chain Reaction (PCR) and DNA sequencing. PCR and sequencing have been used for the genetic identification of oysters as well. Two species of oysters have been identified: Crassostrea rhizophorae and C. brasiliana. In both oyster species P. beihaiensis was the only Perkinsus species detected. In C. rhizophorae, the average prevalence was 82.8% by histology and 65.2% by RFTM. In C. brasiliana, the prevalences were 70.5% and 35.7%, respectively. The higher prevalence of P. beihaiensis in C. rhizophorae was probably influenced by salinity, with which was positively correlated (r> 0.8). In both oysters, P. beihaiensis was located mainly in the gastric epithelium. The infection was generally mild or moderate, without apparent harm to the hosts, but in cases of severe infection, there was hemocytical reaction and tissue disorganization. The generally high prevalence in the region suggests that oysters should be monitored with respect to this pathogen, especially in growing areas.

Resumo Este estudo relata o patógeno Perkinsus beihaiensis em ostras do gênero Crassostrea no litoral do Estado da Bahia (Brasil), sua prevalência, intensidade de infecção e correlação com a salinidade. As ostras (n = 240) foram coletadas entre outubro e dezembro de 2014 em oito estações amostrais entre as latitudes 13°55'S e 15°42'S. Os procedimentos laboratoriais incluíram análise macroscópica, histologia, cultivo em meio de tioglicolato de Ray (RFTM), reação em cadeia da polimerase (PCR) e sequenciamento de DNA. PCR e sequenciamento foram também utilizados para a identificação genética das ostras. Foram identificadas duas espécies de ostras: Crassostrea rhizophorae e C. brasiliana. Em ambas as espécies, P. beihaiensis foi a única espécie de Perkinsus detectada. Em C. rhizophorae, a prevalência média foi de 82,8% por histologia e de 65,2% por RFTM. Em C. brasiliana, as prevalências foram de 70,5% e 35,7%, respectivamente. A maior prevalência de P. beihaiensis em C. rhizophorae foi provavelmente influenciada pela salinidade, com a qual este apresentou correlação positiva (r>0,8). Em ambas as espécies, P. beihaiensis esteve localizada principalmente no epitélio gástrico. A infecção foi geralmente leve ou moderada, sem danos aparentes aos hospedeiros, mas em casos de infecção severa, houve reação hemocitária e desorganização de tecidos. As prevalências geralmente altas na região sugerem que as ostras devam ser monitoradas com relação a este patógeno, principalmente em áreas de cultivo.

Anti-malarial and anti-inflammatory effects of Gleichenia truncata mediated through inhibition of GSK3β

Gleichenia truncata is a highland fern from the Gleicheniaceae family known for its traditional use among indigenous communities in Asia to treat fever. The scientific basis of its effect has yet to be documented. A yeast-based kinase assay conducted in our laboratory revealed that crude methanolic extract (CME) of G. truncata exhibited glycogen synthase kinase-3 (GSK3)-inhibitory activity. GSK3β is now recognized to have a pivotal role in the regulation of inflammatory response during bacterial infections. We have also previously shown that lithium chloride (LiCl), a GSK3 inhibitor suppressed development of Plasmodium berghei in a murine model of malarial infection. The present study is aimed at evaluating G. truncata for its anti-malarial and anti-inflammatory effects using in vivo malarial and melioidosis infection models respectively. In a four-day suppressive test, intraperitoneal injections of up to 250 mg/kg body weight (bw) G. truncata CME into P.berghei-infected mice suppressed parasitaemia development by >60%. Intraperitoneal administration of 150 mg/kg bw G. truncata CME into Burkholderia pseudomallei-infected mice improved survivability by 44%. G. truncata CME lowered levels of pro-inflammatory cytokines (TNF-α, IFN-γ) in serum and organs of B. pseudomallei-infected mice. In both infections, increased phosphorylations (Ser9) of GSK3β were detected in organ samples of animals administered with G. truncata CME compared to controls. Taken together, results from this study strongly suggest that the anti-malarial and anti-inflammatory effects elicited by G. truncata in part were mediated through inhibition of GSK3β. The findings provide scientific basis for the ethnomedicinal use of this fern to treat inflammation-associated symptoms.

Mitral valve Replacement in a 4 yrs old Child: First Time in Bangladesh.

Congenital mitral valve incompetence is a rare and complex congenital heart disease in children. We report, a case of a 4-year-old child admitted to hospital with fever, dyspnea on exertion or feeding and repeated respiratory infection for last 3 years. The transthoracic echocardiogram revealed grossly dilated left atrium and left ventricle and severe mitral regurgitation due to cleft in anterior mitral leaflet. Per-operatively mitral valve annulus was found very much dilated; leaflet thinned out and rudimentary posterior mitral leaflet. Morphology of mitral valve was totally distorted, leaflets were diminutive and beyond repairable. Mitral valve replacement was done with 25 mm Edward Life Science porcine tissue heart valve with total preservation of subvalvular structure and the patient showed dramatic symptomatic improvement and later follow up revealed good LV function with alleviation of symptoms. This is a rare and unusual case of congenital mitral valve disease with better prognosis after surgical replacement with tissue valve.

Quality of antenatal care in primary health care centers of Bangladesh

To find out the quality of ANC in the Upazila Health Complexes [PHC centres] of Bangladesh. This cross sectional study was done in purposively selected three upazilas among the clients receiving antenatal care [ANC]. Data were collected with questionnaire cum checklist in the context of two aspects of quality issues, namely assessment of physical arrangements for ANC [input] and services rendered by the providers [process]. The mean age of respondents was 24.6 +/- 4.5 years. Majority of the respondents were with primary level education [60.3%]. About half [52.8%] of the families had monthly income ranging from 3000-5000 taka [38-64 US$]. Nearly half [48.9%] had no child, little more than one third [42.3%] were primigravida and 528 [57.7%] were multigravida. Out of 528 multigravid respondents 360 [68.2%] took ANC in their previous pregnancy whereas 168 [31.8%] did not take ANC Pregnancy outcome was found to be associated with receiving ANC [? [2] =73.599; p=0.000]. Respondents receiving ANC had more good pregnancy outcome. The mean waiting time for receiving ANC was 0.77 +/- .49 hours. Out of the 13 centers, only 3 [23.1%] have sufficient instruments to render ANC services. Findings showed that where the modes of ANC service delivery in the ANC centers are fairly satisfactory. Though some of the points of standard operation procedures [SOPs] on ANC are not covered by some ANC centers, those were not considered necessary. But, regarding the physical facilities available for rendering ANC services, it is seen that facilities are not quite satisfactory. Number of doctors and nurses are not very satisfactory. One of the centers under this study has no doctor, where ANC services are given by nurses. It can be concluded that the ANC services at the primary health care level is not adequate in Bangladesh. To ensure further improvement of the quality of ANC services, instruments used in logistics and supplies should be enhanced

Efeito analgésico e anti-inflamatório do extrato aquoso das folhas de trevo-roxo (Scutellaria agrestis A. St. -Hil. ex Benth. - Lamiaceae) em roedores / Analgesic and anti-inflammatory effect of the aqueous extract of "trevo-roxo" (Scutellaria agrestis A. St. -Hil. ex Benth. - Lamiaceae) leaves in rodents

Scutellaria agrestis é utilizada por comunidades ribeirinhas do Amazonas principalmente para o tratamento de otites por via tópica utilizando-se o extrato bruto obtido por maceração. O presente trabalho visou investigar preliminarmente o perfil fitoquímico, a segurança toxicológica e as ações analgésica, anti-inflamatória e antiedematogência do extrato aquoso das folhas de S. agrestis. Foram coletados 80 indivíduos da espécie no horto medicinal da Universidade Nilton Lins, Manaus, Brasil. O perfil fitoquímico foi obtido por meio de prospecção da droga vegetal para heterosídeos cianogênicos, terpenos, compostos fenólicos e alcaloides. A toxicologia foi avaliada pelo teste de toxicidade aguda. As atividades analgésicas/ anti-inflamatórias foram analisadas por meio dos testes de formalina em camundongos e a atividade antiedematogência, pelo teste de edema de pata em ratos. Os metabólitos detectados foram fenóis (taninos hidrolisáveis, cumarinas e várias classes de flavonoides) e terpenos (esteroides livres, saponinas). Não foi possível estabelecer DL50, haja visto que o extrato não provocou a morte de nenhum animal durante o teste de toxicidade aguda, provavelmente devido à ausência de heterosídeos cianogênicos na sua composição. Apesar de não provocar morte, considerou-se que o extrato apresenta uma discreta toxicidade, uma vez que foi observada a ocorrência de espasmos na primeira hora de observação dos animais. O extrato apresentou ainda efeito analgésico e anti-inflamatório significativo nas doses de 30, 100 e 300 mg/kg pelo teste da formalina, sendo o resultado na maior dose equivalente ao obtido com a droga padrão (fentanil). No entanto, não observamos efeito antiedematogênico nas doses testadas durante as 5 horas de registro do edema de pata. Os resultados obtidos nesta pesquisa conferem base científica preliminar quanto à segurança e ao efeito analgésico e antiinflamatório da droga vegetal, o que indica que tal espécie é promissora e expressamente recomendada para maiores estudos farmacológicos in vitro e in vivo.

The Scutellaria agrestis is used by Amazonas riverine communities, especially for otitis externa topical treatment, by using the crude extract obtained by maceration. This study aimed to investigate the preliminary phytochemical profile, the safety/toxicity and the analgesic, anti-inflammatory and antiedematogenic activities of the aqueous extract of the S. agrestis leaves. Eighty individuals were collected at the Nilton Lins University medicinal garden, Manaus, Brazil. The phytochemical profile was obtained through a plant drug survey for cyanogenic heterosides, terpenes, alkaloids and phenolic compounds. The extract safety was evaluated by acute toxicity test. Analgesic and anti-inflammatory activities were accessed using formalin test in mice and the antiedematogenic activity, using paw edema test in mice. We detected phenolic (hydrolysable tannins, coumarins and several classes of flavonoids) and terpenoid (free steroids, saponins) metabolites. We could not establish LD50 because no animals died during the acute toxicity test, probably because of the absence of cyanogenic glycosides on the composition of the extract. However, we found that the extract is slightly toxic as animal spasms were observed in the first hour of the test. The extract showed significant analgesic and anti-inflammatory activity on the formalin test (30, 100 and 300 mg/kg p.o.), and the highest dose result was equivalent to the standard drug (Fentanyl). However, no significant antiedematogenic effect was observed during the paw edema test. The results obtained in this study provide preliminary scientific basis about the safety and analgesic/anti-inflammatory actions of the aqueous extract of S. agrestis, which indicates that this species is a promising option for further in vitro and in vivo pharmacological studies.

Anatomy of vegetative organs of Scutellaria agrestis, a medicinal plant cultivated by riverine populations of the Brazilian Amazon

Scutellaria agrestis A. St. -Hil. ex Benth. , Lamiaceae (trevo-roxo) is cultivated for medicinal purposes by residents of the riverine communities in the State of Amazonas, Brazil. This study aimed to characterize the anatomy and to make histochemical analysis on vegetative organs of S. agrestis. Samples of the leaf, stem and root were collected from five plants cultivated by the communities located in the Solimões river, Amazon. These samples were fixed and prepared following standard techniques for scanning electron microscopy and for light microscopy. Histochemical tests were carried out on sections to detect the main classes of compounds present in the secretion. Numerous glandular trichomes are seen in both leaf and stem of S. agrestis. The leaves are amphi-hypostomatics and show dorsiventral mesophyll. Hydathodes are present at the tip of the marginal teeth. Anthocyanin pigments occur into the epidermal cells of the stem, petiole, and abaxial leaf surface. The petiole is concave-convex shaped and bears collateral vascular bundles. The stem showed square-shaped, evident endoderm, collateral vascular bundles and parenchymatous pith. The root displays a typical protostelic structure. Idioblasts containing mucilage and phenolic compounds occur in the cortex. These data are important, as they can be useful to identify this species, contributing to the quality control of the medicinal plant.

Study of antimicrobial susceptibility of clinically significant microorganisms isolated from selected areas of Dhaka, Bangladesh.

Objective: Pathogenic resistance against antibiotics is substantially mounting in the developing countries including Bangladesh. Present study thus attempted to obtain the baseline information on such resistance among the community people coming to the local dispensaries around the city of Dhaka for treatment. Materials and Methods: A total of 2,700 clinical specimens were examined for the presence of Gram positive and Gram negative pathogens. Antibiotic susceptibility tests of the isolates were carried out. Extended spectrum b- lactamase (ESBL) activity, and the presence of methicillin resistant Staphylococcus aureus (MRSA) and S. epidermidis (MRSE) were also detected. Results: Escherichia coli were most prevalent (45.5%) among 1044 pathogenic bacteria isolated from 2,700 samples. E. coli predominated urine, pus, wound swab, blood, high vaginal swab (HVS) and sputum specimens, and exhibited the highest frequency of ESBL activity (35%). Prevalence of Klebsiella spp. and S. aureus among the clinical specimens were 11.5% and 9.86%, respectively. Most of the Gram negative bacilli were found resistant against ciprofloxacin (5 mg), tetracycline (30 mg) and cotrimoxazole (25 mg). Majority of Pseudomonas spp. were found resistant against most of the commonly used antibiotics. Interestingly, around half of the S. aureus isolates were observed to be methicillin resistant, but not vancomycin resistant. Conclusion: Overall, such a revelation of increased antibiotic resistance demands for restrictive and appropriate antibiotic usage in accordance with the updated antibiotic prescribing policy in Bangladesh.

Anatomy and histochemistry of the vegetative organs of Cissus verticillata: a native medicinal plant of the Brazilian Amazon

The purpose of this paper was to carry out an anatomical and histochemical analysis of the vegetative organs of Cissus verticillata (L.) Nicolson & C.E. Jarvis, Vitaceae, to contribute for the attest the taxonomic identity of the medicinal plant. Samples from root, stem, leaf and tendril were cleared, dissociated and processed according to the usual methodology for observation under light and scanning electron microscopes. Histochemical tests were performed in order to identify polysaccharides, phenolic and lipid compounds. The C. verticillata root is typically protostelic, and the stem is eustelic with collateral bundles. The tendril presents structural organization similar to the stem, suggesting a common origin for both. The petiole has an epidermis with ornamented cuticle; the cortex is composed of collenchyma and parenchyma, and the vascular tissues are arranged in collateral bundles. The leaf blade is amphistomatic with non-glandular and glandular trichomes, and the mesophyll is dorsiventral. The identification of the idioblasts as secretion site of the phenolic compounds, mucilage and terpenoids as being responsible for the potential activity of the plant is of fundamental importance for future bioprospecting research on this species.

Chemical composition and histochemistry of Sphagneticola trilobata essential oil

Anatomical and histochemical investigations of Sphagneticola trilobata (L.) Pruski, Asteraceae, secretory structures in leaves and stems and the seasonal variation of essential oils were carried out. Histochemical techniques enabled the specific location of the essential oil accumulation in the internal (canals) and external structures (trichomes). Histochemical analysis showed that the secretory trichomes produced steroids. The highest yield was obtained from plants collected in winter, when it was registered low temperature and precipitation. The essential oil was characterized by high percentage of hydrocarbon sesquiterpenes, hydrocarbon monoterpenes and low levels of oxygenated sesquiterpenes. The major components were germacrene D (11.9-35.8%), α-phellandrene (1.4-28.5%), α-pinene (7.3-23.8%), E-caryophyllene (4.6-19.0%), bicyclogermacrene (6.0-17.0%), limonene (1.8-15.1%) and α-humulene (4.0-11.6%). The percentage of most of the individual constituents present in S. trilobata essential oil changed significantly during the months.

Phytochemical screening, antinociceptive and anti-inflammatory activities of Chrysopogon zizanioides essential oil

Chrysopogon zizanioides (L.) Roberty, Poaceae, is a plant widely used in northeast Brazil in folk medicine for the treatment of various pathological conditions, including inflammatory pain. The present study evaluated the antinociceptive and anti-inflammatory effects of C. zizanioides essential oil (EO) in rodents. EO was further characterized by GC/MS. The major components of EO were identified as khusimol (19.57%), E-isovalencenol (13.24%), α-vetivone (5.25%), β-vetivone (4.87%) and hydroxy-valencene (4.64%). Following intraperitoneal injection (i.p.), EO at 50 and 100 mg/kg significantly reduced the number of writhes (51.9 and 64.9%, respectively) and the number of paw licks during phase 2 (56.7 and 86.2%, respectively) of a formalin model when compared to control group animals. However, EO-treated mice were ineffective at all doses in hot-plate and rota-rod tests. The EO inhibited the carrageenan-induced leukocyte migration to the peritoneal cavity in a dose-dependent manner (34.7, 35.4, and 62.5% at doses of 25, 50 and 100 mg/kg, respectively). In the paw edema test, the EO (100 mg/kg) inhibited all three phases of the edema equally well, suggesting that the EO has a non-selective inhibitory effect on the release or actions of these mediators. Our results suggest possible antinociceptive and anti-inflammatory effects of the EO.

Unmet needs of family planning and practice of family planning in a selected urban to rural migrated population of Dhaka city

To ascertain the unmet needs of family planning and identify the practice of family planning among the urban to rural migrated slum dwellers. A cross-sectional descriptive study was done randomly among selected 600 slum dwellers residing in two selected slums of Dhaka city. Data collected by face to face interview using pretested semi structured questionnaire. Among the respondents 87.7% of were females, illiterate was 60% and most [79.9%] of the houses were katcha and [37.3%] of the families had 5-7 persons in each family. Most families [70%] had monthly income of less than 5000 [app.US$70] taka per month. Majority [89.3%] of the families lived in the villages before coming to Dhaka. About 31.34% were living in present slum for 5-10 years and 80% came for search for better work. It was also found that 33.7% of the couples were not using any contraceptive method. About 29% of these couples did not mention any specific cause for not using family planning method. Only 3.5% of the respondents said of any sort of difficulty in collecting contraceptives and the main difficulty was shyness. As regards knowledge of above consequence of not using contraceptive method 97.7% opined that it would cause unplanned pregnancy, which indicated their awareness towards family planning. The study found that the respondents were aware about the needs of family planning but a great number of them were not using any contraceptive method without any specific reason. Some behavior change communication activities can be run within these areas to bring them under the family planning methods which eventually enhance the population control activity of the country

The Lectin-Like Oxidized Low-Density Lipoprotein Receptor-1 and Cardiovascular Disease.

Lectin-like oxidized LDL receptor-1 (LOX-1), a lectin-like 50-kD receptor for oxidized low-density lipoproteins (ox-LDL), is present primarily on endothelial cells. Oxidatively modified low-density lipoprotein (oxLDL) is implicated in the pathogenesis of atherosclerosis. Endothelial dysfunction is the initial change in the vascular wall that induces morphological changes for atheroma-formation. LOX-1 was identified as the receptor for oxLDL that was thought to be a major cause of endothelial dysfunction. LOX-1 has been demonstrated to contribute not only to endothelial dysfunction, but also to atherosclerotic-plaque formation, hypertension, myocardial infarction and intimal thickening after balloon injury. Studies with transgenic and knockout mouse models have elucidated in part the role of LOX-1 in the pathogenesis of atherosclerosis and cardiac remodeling. Recently, a circulating soluble form of LOX-1(sLOx-1), corresponding solely to its extracellular domain, has been identified in human serum. Circulating levels of sLOX-1 are increased in inflammatory and atherosclerotic conditions and are associated with acute coronary syndrome, with the severity of coronary artery disease, and with serum biomarkers for oxidative stress and inflammation, suggesting that they could be useful marker for vascular injury. Identification and regulation of this receptor and understanding of signal transduction pathways might open new gateways from diagnosis to therapeutics for cardiovascular diseases.

Diagnosis and treatment of intrauterine adhesions.

Intrauterine adhesions develop as a result of intrauterine trauma. The degree of adhesion formation and the impact of the adhesions on the contour of uterine cavity vary greatly. It has been reported that intra abdominal adhesions occur in 60–90% of women who have undergone major gynecological procedures. Hysteroscopy is the gold standard for the diagnosis of severe intrauterine adhesions. Effective methods for preventing adhesions, a variety of surgical techniques and agents have been advocated for the prevention of intrauterine adhesion formation. The present review indicates that there is still no single modality proven to be unequivocally effective in preventing post-operative adhesion formation either for laparoscopic or for hysteroscopic use. Hopefully, the increasing understanding of the future emphasis will probably be on a multimodality therapy, including the use of pharmacologic adjutants in conjunction with a barrier material tailored to the specific operative procedure and a precise surgical technique.

Intravenous regional block is similar to sympathetic ganglion block for pain management in patients with complex regional pain syndrome type I

Sympathetic ganglion block (SGB) or intravenous regional block (IVRB) has been recommended for pain management in patients with complex regional pain syndrome type I (CRPS-I). Forty-five patients were initially selected but only 43 were accepted for the study. The present study evaluated the efficacy of IVRB produced by combining 70 mg lidocaine with 30 µg clonidine (14 patients, 1 male/13 females, age range: 27-50 years) versus SGB produced by the injection of 70 mg lidocaine alone (14 patients, 1 male/13 females, age range: 27-54 years) or combined with 30 µg clonidine (15 patients, 1 male/14 females, age range: 25-50 years) into the stellate ganglion for pain management in patients with upper extremity CRPS-I. Each procedure was repeated five times at 7-day intervals, and pain intensity and duration were measured using a visual analog scale immediately before each procedure. A progressive and significant reduction in pain scores and a significant increase in the duration of analgesia were observed in all groups following the first three blocks, but no further improvement was obtained following the last two blocks. Drowsiness, the most frequent side effect, and dry mouth occurred only in patients submitted to SGB with lidocaine combined with clonidine. The three methods were similar regarding changes in pain intensity and duration of analgesia. However, IVRB seems to be preferable to SGB due to its easier execution and lower risk of undesirable effects.
