Correlation between gonadal development and serum protein pattern
نویسنده
چکیده
Maturity was studied on 273 rainbow trout of both sexes. The female gonads were classed into 3 maturation stages and the male gonads into 4. Characteristic pherograms of both serum protein electrophoresis and total serum protein corresponded with maturation stage. Electrophoretic globulin and total protein fractions increased considerably with spermatogenetically active testes and mature ovaries ; the A/G ration decreased accordingly. These parameters can be used to determine maturity.

Gonadal changes and serum steriod levels during the annual reproductive cycle of the pearl oyster Pinctada fucata gould
The annual reproductive cycle of peal oyster Pinctada fucata was characteised by documenting gonadal development and changes in serum levels of estradiol-17b (E2), testosterone (T) and progesterone (P) in the wild bivalve caught in natural beds in the Persian Gulf throughout the year. Bivalve populations employed in this study spawn in June-July and November-December. The pearl oysters had grou...

A sex steroid-binding protein (SBP) that binds to 17 b-estradiol with high affinity and moderate capacity was identified in the plasma of female and juvenile of kutum (Rutilus frisii kutum) sampled during the early stage of gonadal maturation in October and prior to spawning in March. Mean maximum specific binding (Bmax) and equilibrium dissociation constant (Kd) of the fish were as follows: In...

Background: Meningitis is a common life threatening infection in neonatal period. Diagnostic value of CSF-CRP level in bacterial meningitis in children and adults has been studied worldwide, but there are limited studies on CSF-CRP in neonatal meningitis. This study conducted to assess any relation between CSF-CRP and plasma CRP levels and abnormal CSF findings in neonates suspected to meningit...

The present work focused to explore reproductive biology of fish from different Indian major rivers and its tributaries by comparing ovarian protein, fecundity, oocyte weight, oocyte diameter and condition factor during the spawning period. Correlation between fish reproductive parameter of different Indian major rivers and its tributaries showed a significant relationship. Among studied parame...
