TL;DR: The sensitivity of the plasma membrane to calcium ionophore (A23187) challenge was studied in dog sperm using fluorescein lectin staining for the assessment of acrosomal status and viability and did not differ significantly in the treated and the control groups.
Abstract: The sensitivity of the plasma membrane to calcium ionophore (A23187) challenge was studied in dog sperm using fluorescein lectin staining for the assessment of acrosomal status and viability Second fraction ejaculates from 5 dogs were washed, resuspended in Ca(2+)-free (EDTA-treated), 50, 100, 500, 1000 and 2000 microM/l Ca(2+)-containing Sp-TALP medium and induced with 50, 250, 500, 1000, 2500 and 5000 nM/l calcium ionophore Samples were collected from each aliquot after 30 and 60 min of induction to assess the percentage of acrosome reacted sperm cells (AR rate), viability and motility by fluorescein isothiocyanate conjugated peanut agglutinin (FITC-PNA) and ethidium-homodimer combined staining On each slide, 200 sperm cells were assessed under epifluorescence microscope (x 1250) in a blind manner The response to ionophore challenge (AR rate, viability, motility) varied with Ca2+ and ionophore concentration in the suspension A significantly higher AR rate was detected in samples containing 100, 500, 1000 and 2000 microM/L Ca2+ (> 40%) than in that containing 50 microM/L Acrosome reaction could not be successfully induced in the EDTA-treated sample and in any of the aliquots in which 50, 250 and 500 nM/L ionophore concentrations were used for induction Motility decreased drastically in all of the treated samples and stopped in that sample where as significant AR rate could be detected Viability remained high (> 75%) during the incubation and did not differ significantly in the treated and the control groups

TL;DR: The remote astroglial response (RAR) as mentioned in this paper is a marker of synapase removal during plastic changes either related to function or induced by lesions, and it was shown that synaptic degeneration triggered an up-regulation of GFAP synthesis in the perisynaptic astrocyte processes as a second, cytoskeletal phase of the reaction.
Abstract: The right dorsal lateral geniculate nucleus was stereotaxically destroyed in adult albino rats. After 3 to 150 days of survival the visual cortices from both hemispheres were processed for semithin histology, electron microscopy, GFAP immunohistochemistry and immunoblotting. In visual cortices with histologically disclosed degeneration of the geniculo-cortical tract, a hypertrophy of astrocytes without change in their total numbers was seen from postoperative day 3. From day 7, a rise in GFAP immunoreactivity was observed, reaching its peak between days 11–14, after which a decrease occurred. Observations were confirmed by computer-assisted image analysis of immunohistochemical preparation. Using the immunoblot technique, relative GFAP levels were found to change in a fashion similar to immunohistochemical findings. This showed that synaptic degeneration triggered an up-regulation of GFAP synthesis in the perisynaptic astrocyte processes as a second, cytoskeletal phase of the astrocyte reaction. The phenomenon is denoted as the remote astroglial response (RAR) and is though to be a marker of synapase removal during plastic changes either related to function or induced by lesions. An extrapolation is made to the possible significance of whole-brain GFAP levels in assessing the effects of focal CNS lesions.

TL;DR: Oral tilmicosin at a dose of 25 mg/kg/day for 5 days proved to be effective for the treatment of endemic pasteurellosis of milk-fed calves and the efficacy was the same as that of enrofloxacin.
Abstract: The therapeutic effect of oral tilmicosin was compared with enrofloxacin, and the efficacy of three doses of the drug was examined in two fully randomized blinded field trials. Pneumonic milk-fed calves between 3 days and 2.5 months of age were allocated into two groups in trial 1 (50 animals) and into three groups in trial 2 (69 calves). In the first trial, the animals were treated with 25 mg/kg/day tilmicosin or 2.5 mg/kg/day enrofloxacin in milk for 5 days. In the second trial, the calves received either 25 mg/kg/day tilmicosin for 5 days or 3 days, or else 12.5 mg/kg tilmicosin for 5 days. All calves were clinically examined for 10 days. In the first trial, oral tilmicosin at a dose of 25 mg/kg/day for 5 days proved to be effective for the treatment of endemic pasteurellosis of milk-fed calves. The efficacy was the same as that of enrofloxacin. All three doses in the second trial were effective and were statistically equivalent to the original dose tested.

TL;DR: The results suggested that brainstem pattern generators remain responsive to dopaminergic stimuli in the absence of the main telencephalic (striatal) targets.
Abstract: Metamphetamine in high dose has been reported to induce stereotypic behavior of abnormal form in the pigeon and domestic chick. A number of reports suggested that the target of metamphetamine was the paleostriatal complex, the highest motor center of the avian brain. The present study tested this hypothesis by treating newly-hatched domestic chicks with high dose of metamphetamine (10 mg/kg b.w.) after complete decerebration or sham operation. Stereotypic mandibulations were observed both in sham-operated and in decerebrated birds in similar form following methamphetamine treatment. The results suggested that brainstem pattern generators remain responsive to dopaminergic stimuli in the absence of the main telencephalic (striatal) targets.

TL;DR: The results confirm the high degree of species-specific heterogeneity characterizing the distribution of the opioid peptides in the hippocampal formation.
Abstract: The occurrence and distribution of four opioid peptides (methionine-enkephalin /met-enk/, leucine-enkephalin /leu-enk/, dynorphin-A /dyn-A/, dynorphin-B /dyn-B/) were studied and compared in the subregions and layers of the hippocampi of four rodent species (rat, mouse, hamster and guinea-pig) by means of pre-embedding immunocytochemistry in order to reveal species-specific morphological characteristics. Concerning the mossy fibre system, in the rat met-enk and dyn-A, in the mouse met-enk, in the the hamster dyn-A, in the guinea-pig dyn-B was found to be the dominating immunocytochemically detectable hippocampal opioid peptide. Outside the mossy fibre system, in other hippocampal areas met-enk-immunopositive varicose nerve fibres were most frequently detected in the rat and mouse, whereas dyn-B was the most abundant in the guinea-pig. In the hamster hippocampus all the four studied opioid peptides occurred at least in few varicose fibres. In the rat and mouse enkephalinergic boutons formed pericellular baskets around non-principal cells, whereas dynorphin-immunopositive boutons were visualized in similar arrangement around principal cells (both granule and pyramidal cells) in three of the studied species, except the rat. Among other species-specific differences, the presence of leu-enk-immunopositive perikarya in the golden hamster hippocampus, and a highly ordered leu-enk-immunoreactive fibre system exclusively detected in the CA1 area of the guinea-pig hippocampus are noteworthy. The results confirm the high degree of species-specific heterogeneity characterizing the distribution of the opioid peptides in the hippocampal formation.
