Effect Of Prenatal Exposure To Cigarette Smoke On The Conduction Of Sensory Nerve Fibers In The Rat, Jumah Shakhanbeh Jan 2012

Effect Of Prenatal Exposure To Cigarette Smoke On The Conduction Of Sensory Nerve Fibers In The Rat, Jumah Shakhanbeh

Turkish Journal of Medical Sciences

Aim: To investigate the effect of prenatal exposure to cigarette smoke (CS) on the conduction of sensory nerve fibers in the adult rat offspring. Materials and methods: Pregnant rats were exposed to CS by inhalation during the gestation period. The saphenous nerve in the adult offspring was exposed in vivo, and the conduction parameters of the threshold, maximum strength of stimulation, conduction velocity, and amplitude of compound action potentials (CAPs) of A\alpha\beta-, A\delta-, and C-fibers were examined. Results: Prenatal exposure to CS induced significant reduction (P < 0.005) in the peak amplitude of CAPs of A\alpha\beta- and A\delta-fibers. The conduction velocity of A\alpha\beta-fibers and C-fibers was significantly (P < 0.025-0.05) increased after prenatal exposure to CS. Conclusion: Prenatal exposure to CS attenuates the conduction of sensory nerve fibers in the rat saphenous nerve.

Thirty minutes after induction of epileptiform activity induced by penicillin injection, 0.5, 1, 2, 4, or 8 µg of grayanotoxin-III was intracerebroventricularly administered. Epileptiform activity spike frequency and amplitude were converted into numerical data using software following the experiment. Results: Our results show that grayanotoxin reduces epileptiform spike frequency and amplitude in a dose-dependent manner. Five minutes postinjection, grayanotoxin significantly reduced epileptiform activity, especially at higher doses. …

Profundal Oligochaete Assemblages In Palaearctic Lakes, Tarmo Timm Jan 2012

Profundal Oligochaete Assemblages In Palaearctic Lakes, Tarmo Timm

Turkish Journal of Zoology

The profundal oligochaete fauna is mostly formed of species present also in shallower waters. Endemic taxa have developed only in ancient rift lakes like Lake Baikal. "Common" lakes, mostly of glacial or volcanic origin, are too ephemeral for speciation. In the profundal of larger European oligotrophic lakes, there can occur about 10 tubificid and lumbriculid species. With a decline in dissolved oxygen in water, only 1-2 of them will remain, Tubifex tubifex often being the last survivor. In eutrophic lakes, Potamothrix hammoniensis is the climax species. In the Far East, the profundal is also inhabited by a small assortment of …

The species composition and distribution of large intestinal ciliates was investigated in feces from 5 Cypriot domestic horses living in Northern Cyprus. We identified 9 ciliate genera and 11 species. This is the first report on intestinal ciliates in Cypriot domestic horses, and no endemic species were observed. The genera Cycloposthium, Spirodinium, and Paraisotricha occurred in all animals. The mean number of ciliates was (5.5 ± 4.4) × 10^4 cells mL^-^1 of feces and the mean number of ciliate species per host was 7.2 ± 1.5. The characteristics of the domestic horse ciliates were almost identical to those reported in …

Diet Composition Of Myotis Myotis (Chiroptera, Vespertilionidae) In Western Poland: Results Of Fecal Analyses, Agnieszka Graclik, Oskar Wasielewski

Turkish Journal of Zoology

The diet of greater mouse-eared bats (Myotis myotis) was investigated by analysis of 900 droppings taken from 8 different bat colonies in western Poland. Three taxonomic orders (Coleoptera, Lepidoptera, and Diptera) and representatives of 2 other groups of arthropods (Chilopoda: Lithobiidae and Arachnida: Araneae) were identified in the droppings. Coleoptera was the most abundant prey found in fecal samples in all seasons. Study sites differed significantly in the composition of prey, which probably reflects the local foraging conditions for M. myotis.

Morphological And Histological Effects Of Copper Sulfate On The Larval Development Of Green Toad, Bufo Viridis, Mert Gürkan, Si̇bel Hayretdağ

Turkish Journal of Zoology

Declines in populations of amphibians have been occurring more dramatically over the past 25 years. The declines have various causes. One of the possible causes of amphibian declines is pesticides. Copper sulfate is commonly used as a fungicide in vineyards and gardens in Turkey. In this study, our purpose was to explain the morphologically and histologically acute toxic effects of copper sulfate on Bufo viridis tadpoles. B. viridis tadpoles at Gosner stage 21 were exposed to different concentrations (0.01, 0.05, and 0.1 mg/L) of copper sulfate for 120 h. The LC_5_0 value of copper sulfate was calculated as 0.058 mg/L. …

The Combined Effects Of Salinity And Temperature On The Egg Hatching Rate, Incubation Time, And Survival Until Protozoal Stages Of Metapenaeus Monoceros (Fabricius) (Decapoda: Penaeidae), Mevlüt Aktaş, Nuran Çavdar Jan 2012

The Combined Effects Of Salinity And Temperature On The Egg Hatching Rate, Incubation Time, And Survival Until Protozoal Stages Of Metapenaeus Monoceros (Fabricius) (Decapoda: Penaeidae), Mevlüt Aktaş, Nuran Çavdar

Turkish Journal of Zoology

The combined effects of 3 different temperatures (24, 28, and 32 °C) and salinity levels (35, 40, and 45 g L^{-1}) on the egg hatching rate, incubation time, larval activity, and survival rate until protozoal (PZ1) stage of Metapenaeus monoceros (Fabricius) were investigated under controlled laboratory conditions. The average fertilization rate was 97.25% following spawning. The eggs were stocked in 2-L glass larval culture flasks and received 1 of 9 salinity and temperature combinations in 3 replicates. The eggs hatched in all treatments. Temperature, salinity, and their interaction had significant influences on the hatching rate of the eggs (P < 0.05). The hatching rate decreased as salinity increased and was lowest in all temperature levels at a salinity of 45 g L^{-1}. With regard to the hatching rate, the best combinations were obtained at 35 g L^{-1} and 32 °C (91.67%) and at 35 g L^{-1} and 28 °C (89.17%). The incubation time was shorter at 32 °C (11.2 h) than at 28 °C (14 h) or 24 °C (17.2 h). The development rate from the naupliar stage to the protozoal stage was best at a salinity level of 35 g L^{-1} combined with temperatures of 28 °C and 32 °C. Larval activity was also found to be best at 28 °C and 32 °C at 35 g L^{-1} and 40 g L^{-1}, as compared to that at 24 °C in all salinity levels.

Turkish Journal of Zoology

Genetic data from populations are currently being used in order to assess the conservation status of various species. In this study, the conservation implications of the genetic structure of 3 cave-dwelling bat species in southeastern Europe and Anatolia are discussed. These species are the greater horseshoe bat (Rhinolophus ferrumequinum), the bent-winged bat (Miniopterus schreibersii), and the long-fingered bat (Myotis capaccinii). The conservation status of the species is evaluated using 3 conservation unit approaches, specifically evolutionarily significant unit and management unit definitions and population aggregation analysis. These approaches are implemented simultaneously for the first time for any species in Turkey, through …
