The present investigation was undertaken to evaluate six parents and fifteen hybrids through half-diallel mating system to study general and specific combining ability effects and genetic analysis for various yield and yield attributing characters. Six parents viz., Arka Anamika (P1), Thanvi 66 (P2), Villupuram Local (P3), Dhaanya (P4), Ankur 41 (P5) and Varsha Uphar (P6) were crossed in half-diallel fashion at the Plant Breeding Farm, Department of Genetics and Plant Breeding, Faculty of Agriculture, Annamalai University. Resulting fifteen hybrids along with their parents were evaluated for their combining ability. Observations were recorded on single plant basis. The observations were made on characters namely, days to first flowering, plant height at maturity, number of primary branches per plant, number of nodes per plant, number of fruits per plant, number of seeds per fruit, fruit length, fruit girth, single fruit weight and fruit yield per plant. In half-diallel analysis, the variance of the genotype for all the characters were highly significant indicating high genetic variability among the parents studied. The variance due to GCA was higher than the corresponding variance due to SCA for most of the characters except number of fruits per plant, fruit length and fruit girth. The combining ability variance revealed the preponderance of additive gene action for all the characters studied. The parents P1 and P6 were found as good general combiner. Based on the sca effects, the hybrid P1 x P6 considered as the best followed by crosses P2 x P4 and P3 x P4 considered as the better hybrids.

Plants have been the foundation of several traditional medicinal systems all over the world to provide mankind with new remedies for thousands of years and still continue. In the ancient times human understanding about medicine was always near to some plant. It was the time when medicinal system was entirely based on plants. Among different medicinally useful plants one such plant is called Selaginella bryopteris L. in the botanical world and also known as Sanjeevani due to its magical medicinal properties. It is an herb which is traditionally used in many health-related problems like bacterial, viral, fungal infections, allergy, curing wounds, irregular menstruations and uterine disorders. According to some reports it is also used for fitness and better life span by the tribal communities of India. Different researchers across the country investigated and came up with its unique different properties and new possibilities every time. Apart from these Hindu mythological evidences are there which tells about its extraordinary potential of infuses life to dead. So, it is certainly a matter of more and more research to find out its ever-new hidden capabilities

Authors: Desingh R. , Kanagaraj G.
Published: July 2021

Salinity is one of the most widespread environmental threats to global crop production, especially in arid and semi-arid regions. Photosynthesis and carbohydrates were determined in two ragi (Eleusine coracana (L.) Gaertn) varieties (CO13 and PAIYUR-1), subjected to salt stress of different concentrations (0, 40, 80 and 120mM). Salinity was given as a basal dose and sampling was done in leaves on 30th Days. After Treatment (DAT). There was a marked variation in the photosynthetic rates and ribulose-1, 5-bisphosphate carboxylase activity between the two ragi varieties subjected to salt stress. Photosystem II (PSII) and sucrose phosphate synthase activities were also significantly reduced as measured by salt stressed conditions. The quantity of glucose and sucrose decreased with increasing salt stress while starch showed a reverse trend under salt-stressed conditions. The results revealed that CO-13 exhibits higher photosynthetic rates and activities of ribulose-1,5-bisphosphate carboxylase, sucrose phosphate synthase with photochemical efficiency of PSII compared to PAIYUR-1
MEDIA TRIALS IN THE DISCOURSE OF SERBIAN DAILY PRESS

Published: July 2021

In a contemporary and digital society we have been witnessing frequent changes and everything has become a commodity, even a piece of information. Whether it is news in the media or an opinion written on social media, information is transformed into a product that has its own price, consumers and market. Since the occurrence of the mass media, numerous communication theories have been emerging which try to interpret how content affects the construction of behavior, what type of message produces certain effects and what are the long-term consequences for the society? Applying the quantitative and qualitative content analysis of the front pages of the six daily newspapers in Serbia (Informer, Večernje novosti, Blic, Kurir, Danas and Alo) between January 17 and February 1, 2021 we investigated the characteristics of the models and narratives used in presenting the case of the well-known Serbian director and acting teacher, Miroslav Mika Aleksić, who has been accused of sexually abusing female students. Using the theory of the agenda, the framework theory, as well as the hypodermic needle model, we will try to provide an answer to the question – whether and to what extent we can “defend” ourselves from media opinions which keep “bombing” us every day and can the media “reach a verdict” before legal institutions.

Religie in BMGN: heilig en profaan
Authors: De Maeyer Jan
Published: July 2021

BMGN heeft inzake onderzoek en disseminatie van het thema religie een rol van betekenis gespeeld. Die rol nam BMGN veeleer impliciet op, zelden expliciet. Religie stond niet centraal in de redactionele missie, maar was inhoudelijk wel degelijk aanwezig en bij momenten ook heel zichtbaar. Het tijdschrift verbond niet alleen historici, het verbond ook onderzoek van historici en van andere menswetenschappers uit Nederland en Vlaanderen rond het thema religie en stimuleerde op velerlei wijzen de verspreiding van methodologische vernieuwingen en innovatieve inzichten. Jammer genoeg heeft BMGN religie of religiegeschiedenis nooit expliciet geproblematiseerd. Naast een meer klassieke benadering van religie (de werking van de geïnstitutionaliseerde religies of kerken) lag de focus op de rol van religie in het politieke en sociaal-maatschappelijke leven, maar ook in culturele evoluties (identiteitsopbouw of identiteitsconstructies). BMGN dreef veeleer mee met de ontwikkelingen in de religiegeschiedenis, het was geen trendsetter. In deze vaststelling schuilt een uitdaging voor de volgende tien jaar. Bij een feestnummer hoort een wens: religie mag en kan, als inherent onderdeel van de cultuurgeschiedenis, een explicieter onderdeel worden van BMGN. The BMGN has been of great significance in researching and disseminating religion as a theme. The journal tended to assume this role implicitly but rarely did so explicitly. Religion was not pivotal in the editorial mission but indeed present in substance and at times very visible as well. In addition to connecting historians, the journal brought together research by historians, and by extension other scholars of the humanities, from the Netherlands and Flanders in relation to the theme of religion, and encouraged dissemination of methodological innovations and innovative insights in many ways. Unfortunately, the BMGN has never explicitly addressed religion or the history of religion. Aside from a more conventional approach to religion (the effect of institutionalised religions or churches), the main focus was the role of religion in politics and society, as well as in cultural transitions (identity constructions). The BMGN tended to go along with developments in the history of religion and was not a trend setter. This observation embodies a challenge for the decade that lies ahead. A festive issue includes a wish: religion is permissible and acceptable, as an inherent part of cultural history, as a more explicit part of the BMGN.

De bmgn – lchr is het wetenschappelijke tijdschrift bij uitstek voor de studie van de Nederlandse Opstand. Dit artikel neemt deze algemene vaststelling als uitgangspunt en brengt door een kwantitatieve analyse een aantal ontwikkelingen scherper in beeld. Het bekijkt de chronologische ontwikkelingen in het aantal bijdragen over de Opstand en neemt daarbij ook de taal van de bijdragen en de nationaliteit van de auteurs mee in de analyse. Tot slot wordt gekeken naar de geografische invalshoek van de bijdragen. Op basis van die analyse kan worden vastgesteld dat rond 1990 het Opstandsonderzoek is gaan verbreden door nieuwe vraagstellingen. Een aantal recente nwo-Vici projecten hebben voor een definitieve omslag gezorgd. De vraag is of het onderzoek over de Opstand, zoals het aan bod komt in de bmgn – lchr, ook internationaler is geworden en vooral, wat dat dan precies mag betekenen.

Objective: Supracondylar humerus fractures are the most common surgery requiring upper extremity fractures among children. Kirschner Wire (KW) is one of the important surgical method that is smooth stainless steel pins, and is widely used in orthopedics. The aim of this study is to evaluate the stability difference in supracondylar humerus fractures of children by unscrewed and screwed KW by finite element analysis method.

Material and Methods: In this study, the computerized images of patients who were admitted to the Orthopedics and Traumatology department of a Training and Research Hospital with a diagnosis of pediatric supracondylar humerus fracture were used. A bone model was created using a layer created in the 3D Slicer program version 4.10.2. On this model, osteo-synthesis fixation was performed with Solid Works, with screwed and unscrewed K-wire mounting, divergent and crossed. Afterwards, this model was analyzed in ANSYS 16.0 finite element analysis program.

Results: All KW configuration measurements for screwed forces were found higher than unscrewed forces in both crossed and divergent torques.

Conclusion: The use of screwed K wire was found to be superior to unscrewed wire due to the more stable fixation. During surgery, the configuration of the K wire varies according to the surgeon's experience, fracture type, ulnar nerve damage risk analysis.

Published: July 2021

Concrete is a composite building material made from a combination of aggregate and cement. The limitation of concrete material, in this case, is a fine aggregate (river sand). The utilization of sea sand as an alternative to fine aggregate in the manufacture of concrete is     motivated by the availability of sea sand in nature in very large quantities. This study aims to determine the comparison and how much the compressive strength of concrete produced when using sea sand. The test was carried out when the specimens were 7, 14, and 28 days old with the specimens used in this study were concrete cylinders with a diameter of 15 cm and a height of 30 cm. The results showed that the use of sea sand as a substitute for fine aggregate showed an average compressive strength in 7 days of 18.86 MPa, an average compressive strength of 14 days of 25.52 MPa, an average compressive strength of 28 days of 29.00 MPa. Then for the average compressive strength value of the use of river sand in 7 days is 17.17 MPa, the average compressive strength of 14 days is 23.24 MPa, the average compressive strength of 28 days is 26.41 MPa.
A diversidade confirma seu voto: candidaturas transexuais, folkcomunicação e representação política
Authors: Ferreira Nelson Toledo
Published: July 2021

A proposta deste artigo é refletir sobre os espaços ocupados pelas candidaturas transexuais nas últimas eleições municipais de 2020, no Brasil, correlacionando folkcomunicação, representação política e minorias. Apesar do êxito eleitoral de uma parcela ainda pequena desse segmento em todo o país, com destaque maior nas grandes metrópoles, os (as) transexuais reforçam suas políticas de gênero e abrem novos campos de disputas políticas, como nunca vistos na sociedade brasileira. Nessa perspectiva, o trabalho aponta como a visibilidade midiática potencializa as políticas de comunicação afirmativas da identidade transexual, o que vem possibilitando leituras plurais da sociedade, abrindo novos espaços e democratizando a representação política.

Contribuições estratégicas da Folkcomunicação no contexto de rupturas democráticas.
Authors: Schmidt Cristina
Published: July 2021

​ “Sopram ventos malignos no planeta azul”. Com essa frase Manuel Castells (2018) inicia uma análise dramática sobre as múltiplas crises por que passam os sistemas democráticos no mundo. Desde os países considerados potências econômicas aos subdesenvolvidos, eles se rendem ao neoliberalismo selvagem e recuam suas ações de compromisso social gerando impactos de grande retrocesso em todas as áreas: habitação, alimentação, emprego/renda, saúde, educação, cultural. Uma instabilidade que provocou levantes populares de protesto por meio de grandes mobilizações públicas em inúmeros países durante todo o ano de 2019. E é nesse contexto de rupturas e manifestações que delineamos uma reflexão para entender o papel da Folkcomunicação como método de pesquisa estratégico; seja na identificação dos atores e procedimentos comunicativos de grupos sociais de resistência, seja na utilização dos conceitos que definem os mecanismos comunicativos e as características dos grupos marginalizados. Uma reflexão com abordagem qualitativa descritiva, por meio de levantamento bibliográfico e documental, que foi desenvolvida em duas etapas: a primeira traz o contexto das manifestações em face as rupturas democráticas e, a segunda, elucida aspectos teóricos e metodológicos da Folkcomunicação que auxiliam em um descortinar estratégico. Desse modo, pudemos constatar que a Folkcomunicação é disciplina fundamental para abranger esse contexto e, ainda, esclarecer como os grupos marginalizados criam processos folkcomunicacionais de insurgência, pressão e determinação social.

Published: July 2021

An experiment was conducted to develop cryopreservation protocol for spermatozoa of stinging catfish, Heteropneustes fossilis and to use the cryopreserved sperm in its breeding trials. The activation of sperm motility at various concentrations of NaCl solution was tested and complete activation and inhibition of sperm were obtained at 0.4% and 0.9% to 1% NaCl solution respectively. In toxicity test, sperms were incubated with DMSO, methanol and ethanol at 5, 10, and 15% concentrations where DMSO and methanol produced better motility at 5 and 10% concentration with Alsever’s solution and egg-yolk citrate at 5 and- 10 min incubation period. Three extenders- Alsever’s solution, egg-yolk citrate and Ginsburg Fish Ringer solution and three cryoprotectants- DMSO, methanol and ethanol were used for cryopreservation of sperm, and among the diluents, Alsever’s solution with 10% DMSO showed best performance producing 77.50±3.22% post-thaw motility. On the other hand, egg-yolk citrate and Ginsburg Fish Ringer solution along with 10% DMSO produced 63.75±2.39% and 62.50±3.22% post-thaw motility, respectively. Sperm preserved with Alsever’s solution plus 10% DMSO produced 52.5±3.34% and 38.0±2.39%fertilization and hatching, and those preserved with Alsever’s solution plus 10% methanol produced 46.9±3.11% and 32.7±2.70% fertilization and hatching respectively. The fry produced using cryopreserved and fresh sperm grew well and no significant difference (p>0.05) was found between two groups.
Polyculture potentials of Galda (Macrobrachium rosenbergii) with Heteropneustes fossilis and Clarias batrachus in South-western coastal ghers of Bangladesh
Authors: DAS RAKHI , ISLAM MD. SHARIFUL , AHMED KHAN KAMAL UDDIN
Published: July 2021

Prawn (Macrobrachium rosenbergii) culture is socially more acceptable, technically and economically viable and sustainable. The freshwater catfishes Heteropneustes fossilis (shing) and Clarias batrachus (magur) adapt well to hypoxic water bodies and high stocking densities as well. So, shing and magur may be a good candidate to culture with prawn in ponds/ghers to save the farmers from losing their investment in case of shrimp mortality and getting additional income from fish. With this view, this study was conducted to evaluate the feasibility of polyculture with three treatments each with three replications. Stocking density of shing was variable i.e., 200nos/decimal in T1, 300nos/decimal in T2 and 400 nos/decimal in T3. On the other hand, stocking density of magur and prawn juveniles was 50 and 30 nos/decimal respectably for all treatments. The experimental ghers were treated with salt (NaCl) (150g/decimal), potasium permanganate (5g/decimal) along with lime (125 kg/ha). After stocking fish were fed using floating nursery feed containing 32%, protein and 7% lipid at the rate of 10-2% for shing and magur nursing, floating oil coated grower feed (27% protein and 6% lipid) at the rate of 6-2% for shing and magur grow out and prawn grower (30% protein and 7% lipid) at the rate of 6-2.5% of estimated fish and prawn biomass. At least 10% of stocked catfish and galda were sampled fortnightly using cast net. Physico-chemical parameters of the experimental ghers water were monitored at weekly. After six months of culture the highest growth performance (47.0 g) and survival (19.94%) for shing obtained from T3. Whereas the average growth of shing was recorded 37.02 and 41.14g; growth of magur 99.21g and 99.51g and growth of galda 69.74 and 70.19 for Treatment T1 and T2 respectively. Except ammonia and iron content the other observed parameters of ghers water found congenial for fish health. The value of Benefit-Cost Ratio (BCR) was 1.4 that seems to be profitable and feasible of this polyculture practice.

The effects of vacuum (VP) and 100% N2 modified atmosphere packaging (MAP) on the qualityand shelf-life of sliced pangasius catfish (Pangasianodon hypophthalmus) during refrigerated storage (4°C)were investigated up to 12 days. The values of pH, total volatile base nitrogen (TVB-N) and thiobarbituricacid reactive substance (TBARS) of sliced fish samples during storage under VP and MAP packaging werewithin the limit acceptable for chilled fish. Total viable count (TVC) of pangasius fish, on the other hand,gradually increased from the initial value of 4.32±0.04 to 8.30±0.13 log CFU/g on day 9 for non-sealedpack (control) and 7.64±0.12 and 8.34±0.07 log CFU/g for VP and MAP on day 12. There were nosignificant (p<0.05) differences in TVC values among the three packaging conditions during the storageperiod except on day 9 where significantly (p<0.05) lower TVC values were observed in the VP samplecompared to that of other samples. Based on the bacterial counts of 7 log CFU/g, which is considered as theupper acceptable limit for fresh and frozen fish, the shelf-life was determined as the excess of 6 days forcontrol pack and MAP samples, and excess of 9 days for VP sample. Therefore, VP is a good option toincrease the shelf-life of wet fish, which can be adopted by the superstores to display their products withextended shelf-life.

Published: July 2021

Science has shown us that since Earth’s creation, climate has been affected by natural occurrences,both within and outside the climate system, but in recent years, climate is also being affected by actions andinactions of the human race. Climate system changes affect all life on earth, but fisheries are affected inparticular, because almost three-quarters of the Earth’s surface is water and home to a variety of aquatic life.Changing weather is producing more droughts, floods, rising sea levels, salt water intrusion of fresh water,acidity in the oceans and ocean warming. This paper discusses how climate change is affecting both marinelife in the oceans and aquatic species in fresh water, as well as the effects of these changes on the seafoodsupply chain and other revenue sources in coastal areas. Factors causing climate change and actions needed tomitigate these changes are also discussed.

The objective is to involve up-scaling biotechnological activity toprepare by-product(s) utilizing every-parts of the fish. The project will reduce organic waste, generate higherrevenue and improve quality-life of farmers. Here is a case-study as a reference, reviewing outcome of adrug discovery R & D on the species in Malaysia since 1985 where Haruan, a good source of protein, theundisputed oral traditional medicine inducing quick recovery for ladies after giving birth. Accordingly, stockidentification and environmental physiology data of this indigenous species were obtained: inhabiting warm,clean, shallow slow-running or stagnant water with aquatic-flora or dead-wood as hiding/resting placeambushing preys. This information is key to a sustainable commercial-scale aquaculture Haruan Agro-Pharmaceutical Industry (HAPI); comprising pre-harvest; and extended to post-harvest activities. Theestablishment is to maintaining and sustaining the unique biochemistry reflecting carnivorous behaviorconsuming other fishes, amphibians and reptiles. The fish contains high-protein (>60 %), low-fat (<3 %)and comprehensive dietary minerals with a good amino acid profile, high in Glycine and fatty acid with ?-6(Arachidonic Acid), ?-3 (Docasahexaenoic Acid or DHA), albumin and cyclic-peptide N-arachidonylglycine@ NAGly. Hence, a proprietary standard operating procedure as a technology had been established, andsuccessfully performed for extracting the biochemistry through a Pressurized In-Water Extraction (PIWE).The extract is termed as Haruan Manan (HM). However, actual protocol is a trade-secret. It is a bioactive,key ingredient in every Haruan Biomedical Product (HBP) inducing wound-healing, reducing-pain, treatinginflammation and inhibiting growth of pathogenic bacteria (including Staphylococcus aureus and Helicobacterpylori). These four physiological steps to healing, curing and treating are demonstrated by our first product:Haruan Cream containing 5% of the HM for skin disease, eczema. HM is a signature, Active PharmaceuticalIngredient (API); and we are discussing, demonstrating and high-lighting potential of C. striata as functionalfood,nutraceuticals and API.

A study was conducted to investigate fish species availability and socio-economic conditions offishermen of the Bergobindopur baor of Jashore district, Bangladesh. Data were collected from 30 fishermenof the baor through questionnaire interviews and focus group discussion. Various indigenous fish like rui,punti, tengra, shol, ayre, chital, mohashol and a few exotic fish like tilapia, silver carp, common carp, andgrass carp are available in Bergobindopur baor. Prices of fishes varied from species to species but high pricedfish were mohashol, chital, and shol. Kochal jal, net jal, and hela jal are used for fishing. A large portion offishermen (70%) were Hindu, almost all were male (96%) , married (91%) and middle aged (55%). Bothjoint and nuclear families were found among the fishermen. Yearly income of the maximum fishermen wasbetween Tk. 31000 and Tk. 50000. Non-constructed houses were more abundant (88%) and majority (61%)had electricity facilities. All fishermen used tube well water, sanitary latrines and took allopathic (80%)treatment which indicated positive signs for health condition. Through fishing, their socio-economic conditionhad improved. About 60% fishers had bank accounts and all sent their children to school as well as farmedcattle. However, the fishers faced some problems like lack of sufficient boats and gears, transportationproblems, inadequate training facilities, lack of financial supports, lack of awareness etc. Therefore, moreinstitutional, organizational, technical and credit supports are required to minimize their difficulties andensure their socio-economic betterment and sustainable livelihoods

Bivalves are filter feeders that ingest particles from the surrounding water, including pathogens,which could cause illness in consumers. In Samar, Philippines no data on the microbial quality of undulatedsurf clam (Paphia undulata) have previously been reported. Thus, this study was conducted to determine themicrobial quality of the species in selected areas in Samar, Philippines (Pinabacdao, Zumarraga andVillareal). The total plate count (TPC) and total Vibrio count were beyond the standard limits set by the Foodand Drug Administration (FDA), although Salmonella was not detected in any samples. The TPC ofundulated surf clam was 5.9-6.3 log CFU·g-1 in Pinabacdao, 4.9-6.0 log CFU·g-1 in Zumarraga, and 6.3-7.2log CFU·g-1 in Villareal. The total Vibrio count was 5.1-5.7 log CFU·g-1 in Pinabacdao, 3.9-4.6 log CFU·g-1in Zumarraga, and 6.1 log CFU·g-1 in Villareal. Bivalves in these areas should undergo purification process,such as relaying or depuration

The study was carried out infourselected farmer’s pond in Netrokona sadarand Barhatta upazillas(sub district) under Netrokona district during April to September 2019 having average pond area of 0.14 haeach. The ponds were prepared by removing aquatic vegetation and unwanted fish and other animals, andapplying with lime at the rate of 250 kg/ha. Five days after liming, water was supplied from shallow tubewell to the ponds and filled up to the depth of 1.5 m. The fry of Pabda (Ompok pabda) and Gulsha (Mystuscavasius) with Rohu (Labeo rohita) were stocked at the rate of 175000; 87,500 and 2000/ha, respectively.After stocking, fish were fed at a rate of 5-12% of body weight with supplementary feed (30% crudeprotein). Fish sampling were done at monthly interval to know the fish growth status and also to adjust feedration. After six months rearing, fish were harvested by repeated seine netting. Total bulk weight and numberof fish from each pond was recorded. Survival and gross production of fish of each pond were estimated. Theharvesting weight of pabda ranged from 33 to 36g. While the harvesting weight of Gulsha and Rohu rangedfrom 26-27g and 591-614g, respectively. Based on the number of fish harvested at the end of the experiment,survival ranged from 75 to 88%.Total production of Pabda (O. pabda) and Gulsha (M. cavasius) with Rohuwas estimated at 5202, 1772 and 1066 kg/ha, respectively. The total production of fish as recorded in trialponds were 8043 kg/ha

Gel forming ability of fish muscle is greatly influenced by the storage temperature and rigor stages.The present study was carried out to assess the changes in gel forming ability and protein solubility ofpangasius (Pangasianodon hypophthalmus) muscle stored at room temperature (28 to 32°C) and in ice. Rigormortis in fish sample kept at room temperature (RT) and in ice started 1hr after death. The rigor-indexreached a maximum 73.33% within 7 hrs after death at RT and a maximum 87.09% within 4 hrs in icestorage. At pre-rigor stage, the breaking force (BF) was 646.00 (±2.08g) which decreased to 266.67(±3.53g) at post rigor stage at RT and from 660.33 (±1.45g) to 420.67 (±1.45g) in ice in one step stage. AtRT, grade of folding test (FT) decreased from “AA” to “A” and score of teeth cutting test (TCT) from 8 to4. In ice also grade of FT and score of TCT decreased. Similarly, in two-step heating gels, BF decreasedfrom 994.33 (±2.33g) to 403.00 (±1.15g) at post rigor stage at RT and 995.33 (±1.45g) to 552.67(±3.71g) in ice. Immediately after catch myofibrillar protein solubility was 86% which declined below 30%after 24h of storage at RT and below 30%after 28 h of storage in ice. The study concludes that the rigorperiod of pangasius may be extended up to 18 h by storing the fish in ice while at RT this period is only about5 h, which might contribute to slow down the gel degradation process.

Background: Benign Prostatic hyperplasia is one of the commonest physiological ageing process of males. Among these, there arechances of conversion of this benign condition into malignancy. Initially benign prostatic hyperplasia was tried to be controlled withmedication. Then came the era of open surgery in the form of Trans-vesical prostatectomy and now-a-days minimally invasive techniqueof trans-urethral prostatectomy is on the surge. With the passage of time, there is increasing trend in performing histo-pathology of anytissue taken out from the body and this has resulted in very fruitful results.Objective: To determine the frequency of carcinoma prostate in those patients who were clinically suspected as having bening enlargedprostate.Material and Methods: This study was conducted in Surgical units and Urology unit of Saidu Group of Teaching Hospitals, Swat from2013 to 2015. A total of 200 patients were included in the study. An exclusion criteria was made so as to exclude confirm cases ofcarcinoma prostate from the study. After performing trans-vesical and trans-urethral prostatectomy, the specimens were sent for histopathology.Results: 200 patients were selected for the study who were clinically assigned as having benign prostatic hyperplasia according to ourinclusion criteria. Out of these 200 subjects, 32 (16%) came out to be having carcinoma prostate while 168 (84%) patients retained theoriginal clinical diagnosis upon histo-pathology.Conclusion: Rather than assigning a patient as having benign enlarged prostate on clinical grounds, it is better to perform histopathologybecause there is a vast difference of management plan of a benign condition as compared to a malignant condition.
