Variability of growth, maturation and fecundity of gibel carp (

The goal of present study was to examine gibel carp, Carassius gibelio (Bloch, 1782) growth, maturation, fecundity and ripe eggs size under pond fish culture conditions and conditions of natural water bodies of the River Syrdarya, Uzbekistan. Gibel carp originally came from the River Amur (Russia), it was introduced to Uzbekistan in 1950s. Recently, it is wide spread species in local ichthyofauna. Females matured for the first time at age 2 years: in ponds in 8-10 cm in standard length, in the river in 18-20 cm. The GSI increased to spawning up to 2.9 – 25%. In fish farm ponds absolute fecundity was 1,4 – 51,300 eggs, in the River Syrdarya - 9,2 – 91,400 eggs. Relative fecundity in all populations was 21 – 590 eggs/g in weight of gutted fish. In April, there were two peaks of ripe and yolk eggs size: 1st - 0.89 – 1.69 mm, 2nd – 0.69-0.9 mm

IMMUNOLOGICAL CHARACTERIZATION OF THE PATIENTS WITH CHRONIC UVEITIS CAUSED BY HERPES AND CYTOMEGALOVIRUS

Abstract. The study included patients with chronic uveitis caused by herpes simplex virus (HSV), or mixed HSV/ cytomegalovirus (CMV) infections. Deficiencies in CD3+ and CD4+ T lymphocytes and significant increase of CD8+ lymphocyte subpopulations were found in posterior uveitis. A single-pathogen (HSV) infection was characterized by decreased expression of CD3+ and CD4+ lymphocytes, IgG hypoglobulinaemia. Irrespectively of etiology, both groups of the patients exhibited sharp increase in CD16+ cells, as well as suppressed CD25+ receptors for IL-2, increased numbers of activated CD38+ lymphocytes, enhanced expression of late activation markers (CD95+ and HLA-DR+) in both mixed and single-pathogen uveitis. IFN-alpha is detected at low concentrations, or is absent; increased TNF-alpha production was noted in the tears in cases of posterior uveitis.Statistically significant interrelations have been found between expression of HLA-DR+, and CD3+; CD95+ and HLA-DR+; CD95+ lymphocytes and TNFalpha levels in the course of chronic persistence of Herpesviridae in the patients with chronic uveitis. The degree of immunological disturbances correlated with severity of clinical features.</p
