Transplantation of kidney with multiple arteries

One hundred and nine kidney transplantations have been performed. All the patients have been divided into 2 groups: 1st group consisted of 91 patients whose transplant had 1 artery, 2nd group -- 18 patients whose transplant had 2 to 5 arteries. In 2.5 years after transplantation the function of transplant and degree of arterial hypertension were identical in both groups. It is concluded that the short- and long-term results of transplantation of kidneys with multiple arteries don't differ from ones with single artery.     

A synthetic NCAM-derived peptide, FGL, protects hippocampal neurons from ischemic insult both in vitro and in vivo

There is a major unmet need for development of innovative strategies for neuroprotection against ischemic brain injury. Here we show that FGL, a neural cell adhesion molecule (NCAM)-derived peptide binding to and inducing phosphorylation of the fibroblast growth factor receptor (FGFR), acts neuroprotectively after an ischemic insult both in vitro and in vivo. The neuroprotective activity of FGL was tested in vitro on dissociated rat hippocampal neurons and hippocampal slice cultures, using a protocol of oxygen-glucose deprivation (OGD). FGL protected hippocampal neurons from damage and maintained or restored their metabolic and presynaptic activity, both if employed as a pretreatment alone to OGD, and if only applied after the insult. In vivo 24 h pretreatment with a single suboccipital injection of FGL significantly protected hippocampal CA1 neurons from death in a transient global ischemia model in the gerbil. We conclude that FGL promotes neuronal survival after ischemic brain injury.     

Unexpected effect of haemodialysis on salivary hepatocyte growth factor.

Sir, Periodontal disease causing premature tooth loss is common andaggressive in younger and still dentulous patients undergoingmaintenance haemodialysis (HD) [1]. Recent studies showed thathepatocyte growth factor (HGF), a pluripotential, ubiquitousand mostly regenerative cytokine, is strongly involved in thepathogenesis and progression     

Environmental monitoring in the foci of parasitic diseases in the town of Belgorod-Dnestrovsk,Odessa region

The paper shows a role of environmental objects in the formation of parasitic diseases in Belgorod-Dnestrovsk, developmental changes in intestinal parasitic cenoses in children from closed institutions. To attract parasitologists to the diagnosis of acute intestinal infections of unspecified etiology increases the percent (49.5 to 82.0) of positive results. The findings show what environmental objects should be monitored in the sanitary and parasitological contexts: soil, vegetables, greens in helminthiasis; utensils in preschool children' establishments in contact helminthiasis; drinking water, vegetables, greens in giardiasis.     

Gilles de la Tourette's syndrome

Tourette's syndrome (TS) is a childhood onset neurological disorder characterized by motor and vocal tics. It may be associated with a number of co-morbidities including attention deficit hyperactivity disorder, obsessive compulsive symptomatology, and behaviour disorders. Prevalence of TS is higher than previously thought, and may be present in up to 2% of the population. Tourette's syndrome has a significant genetic component. Inheritance may involve several mechanisms including autosomal dominant, bilinear, or polygenic mechanisms. Pathophysiology is still unknown, although is thought to involve striatocortical circuits. Treatment begins with modification of the work and home environment. For more severe cases, medications such as tetrabenazine and neuroleptics may be helpful. Treatment of co-morbidities needs to be considered, as these may result in moredisability than the tics themselves.     

Signal transduction pathways implicated in the decrease in CYP1A1, 1A2 and 3A6 activity produced by serum from rabbits and humans with an inflammatory reaction

Incubation of serum from rabbits with a turpentine-induced inflammatory reaction and from humans with an upper respiratory viral infection with hepatocytes from rabbits with a turpentine-induced inflammatory reaction for 4h reduces total cytochrome P450 content and activity of cytochrome P450 isoforms CYP1A1/1A2 and 3A6 without affecting the expression of these proteins. To document the signal transduction pathways implicated in the decrease in CYP1A1/1A2 and 3A6 activity, hepatocytes from rabbits with a turpentine-induced inflammatory reaction were incubated with serum from rabbits with a turpentine-induced inflammatory reaction, serum from individuals with a viral infection and interleukin-6 for 4h in presence of inhibitors of protein kinases. The sera-induced decrease in CYP1A1/1A2 and 3A6 activity was partially prevented by the inhibition of Janus-associated protein tyrosine kinase, double-stranded RNA-dependent protein kinase, protein kinase C, and p42/44 mitogen-activated protein kinase. The serum from rabbits with a turpentine-induced inflammatory reaction increased the phosphorylation of Erk1/2, effect prevented by PD98059 but not by bis-indolylmaleimide, a specific inhibitor of protein kinase C. The results demonstrated that the decrease in total cytochrome P450 content and in CYP1A1/1A2 and 3A6 activity by sera and interleukin-6 involves the activation of protein tyrosine kinases, p42/44 mitogen-activated protein kinase and protein kinase C. Indirect evidence supported that nitric oxide is implicated in the decrease in activity of these enzymes.     

Complete recovery of visual functions after multimodality treatment for intrinsic chiasmatic-hypothalamic astrocytoma--case report

A 21-year-old female was admitted with complaints of severe impairment of vision. The visual acuity was 0.02 in both eyes along with residual visual fields and central scotomas. Neuroimaging disclosed a chiasmatic-hypothalamic glioma. Surgery was performed with partial removal of the intrachiasmatic part of the intrinsic tumor. The histological diagnosis was fibrillary astrocytoma. Progressive recovery of vision began in the first week after surgery. Adjuvant treatment included one course of fractionated radiation therapy and six courses of chemotherapy. Complete recovery of visual acuity occurred after 10 months, and the visual fields were restored after an additional 6 months. Her vision has been stable during 2 years of follow up. The prognosis for recovery of vision after treatment of optic pathway gliomas mainly depends on the severity of visual loss at admission and is negatively influenced by intrinsic tumor growth, symmetrical extension, and involvement of the chiasm. Despite the presence of all these factors in the present case, multimodality management resulted in the complete recovery of visual functions. Surgery may be indicated in cases of intrinsic chiasmatic gliomas complicated by severe visual loss.
