Background: Despite several studies many questions remain regarding how varicocele develops its adverse effect on testicular tissue. Spermatogenesis cell lineage needs carbohydrates as a main source of energy for cell division. Any disruption in glucose transporting system in seminiferous tubules results in remarkable decrease in germinal cells biological function. Therefore present study was c...

A series of new Schiff bases were synthesized by condensation of isatins with the nalidixic acid-l-amino acid hydrazides. Prior to hydrazide formation, a peptide linkage has been prepared via coupling of nalidixic acid with appropriate l-amino acid methyl esters to yield 3a-c. The chemical structures of the new Schiff bases (5b and 5d-h) were confirmed by means of IR, NMR, mass spectroscopic, a...

Schiffbase was obtained by condensation of camphor with 4-amino-phenol .The charge transfer complex of the Schiff base as a donor molecule with picric acid as acceptor molecule in methanol were estimated. Schiff-base compound and charge transfer complex were identified by elemental analysis, infrared spectra and UV-visible spectra.The physical parameters of the CT complex were calculated by app...

This study was conducted to evaluate histochemical alterations of river buffalo’s uterine wall acid andalkaline phosphatases (ALP and ACP), lipase and carbohydrate ratio during follicular and luteal phases.Forty apparently healthy and non pregnant river buffalos were considered for removal of the uterus aftersacrifice in slaughterhouse. All dissected uteri were divided into two luteal (by obser...

Reticular fiber consists of one or more types very thin and delicately woven type III collagen strands, which form a highly ordered cellular network provide supportive network. Since most these are combined with carbohydrates, they react silver stains periodic acid-Schiff reagent, but not shown by ordinary histological like those using hematoxylin. In this study, it was aimed to determine the r...

The patterns of periodic acid-Schiff (PAS) staining of extracellular matrix in histological sections of certain melanomas may be predictive of outcome. Recent in vitro and molecular genetic data suggest that the appearance of these patterns in both uveal and cutaneous melanoma is a function of aggressive tumor cells. We studied 96 patients with primary cutaneous melanomas treated at the Univers...

of trypsin without EDTA. A monolayer of radioactively labelled BHK cells was incubated at 37°C for2min in 0.25 % trypsin; one half of the cells in suspension were harvested, washed and assayed for adhesion, and the other half of the cells were incubated for a further 15min in 0.25% trypsin before harvesting, washing and assaying for adhesion. Cells incubated in trypsin for only 2min did not sho...
