There is good evidence for impairment of spermatogenesis and reductions in sperm counts and testosterone levels in chronic alcoholics. The mechanisms for these effects have not yet been studied in detail. The consequences of chronic alcohol consumption on the structure and/or metabolism of testis cell macromolecules require to be intensively investigated. The present work reports the effects of chronic alcoholism on contents of free amino acids, levels of cytochrome P450 3A2 (CYP3A2) mRNA expression and DNA fragmentation, as well as on contents of different cholesterol fractions and protein thiol groups in rat testes. Wistar albino male rats were divided into two groups: I - control (intact animals), II - chronic alcoholism (15% ethanol self-administration during 150 days). Following 150 days of alcohol consumption, testicular free amino acid content was found to be significantly changed as compared with control. The most profound changes were registered for contents of lysine (-53%) and methionine (+133%). The intensity of DNA fragmentation in alcohol-treated rat testes was considerably increased, on the contrary CYP3A2 mRNA expression in testis cells was inhibited, testicular contents of total and etherified cholesterol increased by 25% and 45% respectively, and protein SH-groups decreased by 13%. Multidirectional changes of the activities of testicular dehydrogenases were detected. We thus obtained complex assessment of chronic alcoholism effects in male gonads, affecting especially amino acid, protein, ATP and NADPH metabolism. Our results demonstrated profound changes in testes on the level of proteome and genome. We suggest that the revealed metabolic disorders can have negative implication on cellular regulation of spermatogenesis under long-term ethanol exposure.

Curcuma Longa: Staining Effect on Histomorphology of the Testis
Background: The use of non-allergic, non-toxic and eco-friendly natural dyes has become a matter of significant importance due to the increased environmental awareness in order to avoid some hazardous synthetic dyes.
Method: The ethanolic extract of Curcuma longa was diluted using 1% acetic acid in 70% ethanol to a concentration of 0.2 g/ml. It was used to stain histological sections of the testes for 15 minutes. Curcuma longa was also used as a counter stain for Haematoxylin. Phytochemical constituents were investigated.
Results: The Curcuma longa dye distinctly stained the seminiferous epithelium and interstitium yellow. Curcuma longa provided a good counter stain for Haematoxylin, taking up the acidic staining characteristics with Haematoxylin staining the basic staining characteristics. Phytochemical screening revealed the presence of saponins, alkaloids, tannins and flavonoids.
Conclusion:Curcuma longa has good potential for use as a counter stain for Haematoxylin in the staining of tissues in lieu of Eosin.
