Taxonomic study of Family Papilionaceae of District Swabi, Khyber Pakhtunkhwa,

Abstract: A total of 26 species belonging to 14 genera of family Papilionaceae were collected and identified from the research area. The members of this family were found in abundance that is why infective amount of species were identified. Madicago was dominant genus with 6 species, Trifolium with 4 species, Lathyrus with 3 species following by Trigonella and Vicia with 2 species each. The rest of genera i.e Alhaji, Arachis, Cicer, Dalbargia, Erythrina, Melilotus Pisum, Phaseolus and Sesbania were represented by single species each. The reported species of family were include both the wild and cultivated species.15 species (57.7%) were wild and 11 species (42.3%) were cultivated. The reported species of the family Papilionaceae were classified into herbs 20 species (77%) shrubs and under shrubs 4 species (15.3%) and trees 2 species (7.7%).

Diversity of weeds and their ecological characteristics at Tehsil Manki Sharif, District Nowshera, Pakistan.

Abstract: The present study was conducted in order to assess the weed flora of Tehsil Manki Sharif, District Nowshera Pakistan during 2013-14. A total of 46 weed species belonging to 21 families and 43 genera were reported from the research area. The dominant family was Asteraceae with 11 species followed by Papilionaceae and Plantagonaceae with four species each. The family Poaceae was represented by four species; Solanaceae, Euphorbiaceae and Brassicaceae were having two species each, while the remaining families shared only one species each. In survey, the dominant life form was therophyle (36 species with 76%), followed by Geophyte (7 species with 15.2%), and hemicryptophyte (4 species with 8.6%). The leaf size spectra showed that mesophylls were the dominant class with 14 species from the study area, followed by microphyll with 10 species and Nanophyll with 8 species.

Computed tomography (ct) scan; ring enhancing lesions on brain

Abstract: 7 ORIGINAL PROF-2613 ABSTRACT… Ring enhancing lesions are a common neurological problem seen in either gender and in all age groups. Objectives: To determine the clinical presentations and etiological factors in patients with ring enhancing lesion on CT scan brain. Design: Case series study. Period: One year. Setting: Department of medicine, Liaquat University Hospital, Hyderabad. Patients and methods: Subjects of either sex ≥12 years of age, presented with seizures, fever, focal neurological signs and deficit, headache, weight loss and vomiting and had single or multiple ring enhancing lesions on computed tomography (contrast CT brain film) were enrolled and entered in the study. CT scan brain was advised to evaluate any identified lesion and then certain specific biochemical tests were also advised to detect the particular existence etiological factor. The data was analyzed in SPSS 16 and the frequency and percentage was calculated. Results: During one year study period, total 50 subjects were detected as ring enhancing lesion on CT scan. The mean age ±SD of the over all population was 28.87±4.84 whereas the mean age ±SD of male and female population was 27.76±6.53 and 30.76±5.83 respectively. Ring enhancing lesions were right sided in 30 patients (60%), on the left side in 15 (30%) and bilateral lesions were identified in 6 subjects (10%) on brain imaging. Majority of the ring enhancing lesions were single 45 (90%) and the parietal lobe was observed as the commonest site. The headache, seizures, fever, pyramidal signs and papilledema was identified the common clinical features whereas the common etiological factors responsible for ring enhancing impression on brain CT scan were tuberculoma 17(34%), brain tumor 12(24%), metastasis 05(10%) and brain abscess 04(08%). Conclusions: The male population was predominant while the seizure was observed as common clinical feature whereas the tuberculoma, brain tumour and metastasis are the common etiological factors responsible for ring enhancing lesion on brain imaging.

The study of algae: the non-vascular aquatic weeds from various fresh water bodies of Peshawar Pakistan.

Abstract: The study of algae is very attractive due to their prehistoric and cosmopolitan nature. Algae are capable to survive in uncertain environment. Peshawar has many rivers and lakes i.e. River Kabul, Adezai, Naguman, Shah Alam and Bara River, where fresh water algae may exist abundantly, but very little notice has been paid to the algal diversity of all these rivers of Peshawar. To investigate the algae of Sheikh Muhammadi area of District Peshawar, a comprehensive study was conducted during 2013. A total of 22 algal species belonging to 10 families were recorded. Among them Oedogoniaceae appeard as the dominant family with 5 species followed by Stegeoclonium (3 spp.) while Cladophoraceae and Bulbochaete having two species each. Characiaceae, Scenedesmaceae, Oocystaceae, Centritractaceae, Coleochaetaceae, Tetrasporaceae Aphanochaete, Gongrosira, Characium, Cenedesmus, Closteriopsis, Centritractus, Coleochaete and Chaetopeltis got one species each. Some of the algal species are very useful for medicinal purpose, while others can be used as feed or food. Still most of the filamentous are noxious weeds of water bodies and hinder the intended use of water body. This study covers only a small portion of algae and a lot of species are still to be discovered, hence further studies are suggested to be undertaken in this regard.

In vitro antioxidant and antiglycation studies on african mistletoe (T. bangwensis (Engler and K. Krause), Danser) and ring worm plant (S. alata (Linn.) Roxb) from Nigeria

Abstract: The antioxidant activity of crude methanolic extracts and fractions of African mistletoe (Tapinanthus bangwensis) and Ring worm plant (Senna alata) leaves from Nigeria was investigated. In an in vitro free radical scavenging activity against 1,1-diphenyl-2-picrylhydrazyl (DPPH), superoxide scavenging (SOS) activity and chelation of iron (II) ion [Fe 2+ ] in the presence of ethylenediaminetetraacetic acid (EDTA), ethyl acetate (EtOAc) fractions of both plants showed antioxidant activity in DPPH (83.95±0.04 and 66.35±0.07%), SOS activity (86.10±0.03 and 83.14±0.07%) for T.bangwensis and S.alata respectively compared to control (n-propyl gallate) which showed 90.31±0.01% inhibition). Inhibition of Fe2+ chelation showed 84.29±0.06 and 81.59±0.04% for T.bangwensis and S.alata respectively when compared to control, EDTA (97.60±0.07%). Furthermore, in an advanced glycation end products (AGEs) study, the in vitro inhibition (≥50%) was highest in EtOAc fraction of S.alata (57.06±3.20 and 65.53±1.76%) at 0.25 and 0.5 mg/mL, respectively when compared to the control, rutin (86.00±1.50%). In conclusion, results of the study showed possible antioxidant as well as antiglycation potential of leaves of Tapinanthus bangwensis and Senna alata.
