Tissue Distributions and Toxic Effects of Hexavalent Chromium in Laboratory-Exposed Periwinkle ( Linnaeus).

The increased use of hexavalent chromium (Cr) in various industrial applications has contributed to its elevated levels in the environment, especially the aquatic environment. Thus, there is the potential for accumulation of Cr in the tissues of aquatic organisms and consequent toxic effects. The toxic effects of Cr in aquatic organisms have been widely reported; however, little is known about the patterns of tissue accumulation of Cr and its toxicity in aquatic mollusks.

Tissue Accumulation, Cytotoxicity, Oxidative Stress, and Immunotoxicity in African Catfish, Clarias gariepinus Exposed to Sublethal Concentrations of Hexavalent Chromium.

Hexavalent chromium (Cr) is one of the stable oxidation states of chromium that has been reported to elicit various toxic effects in aquatic organisms. However, the mechanisms of Cr toxicity are still poorly understood. Thus, the present study investigated the tissue accumulation, cytotoxic, oxidative stress, and immunotoxic effects of Cr in juvenile Clarias gariepinus.

Aqueous extract of Tetrapleura tetraptera fruit peels influence copulatory behavior and maintain testicular integrity in sexually mature male Sprague-Dawley rats: Pro-fertility evaluation and histomorphometry evidence.

Tetrapleura tetraptera (TT) has been used as a spice, dietary supplement and medicine for various ailments. This study evaluate influence of Tetrapleura tetraptera extract on testis and copulatory behavior in sexually mature male rats. Thirty-two male and sixty-four virgin female rats weighing 150-200 g were used for this study.

Protective effects of aloe vera gel (aloe baberdensis Miller) on aluminum chloride-induced reproductive toxicity in male Wistar rats.

Objective: This study aims at investigating the protective effects of aloe vera gel on aluminum chloride-induced testicular toxicity of adult Wistar rats.

Methods: Twenty male Wistar rats were randomly divided into four groups (A, B, C, and D) with five animals per group. Group A serves as the control group and received distilled water (1ml/Kg).

Effects of Aqueous Leaf Extract of Lawsonia inermis on Aluminum-induced Oxidative Stress and Adult Wistar Rat Pituitary Gland Histology.

Objectives: The aim of this study was to investigate the antioxidant effect of aqueous Lawsonia inermis leaf extract on aluminum-induced oxidative stress and the histology of the pituitary gland of adult Wistar rats.

Methods: Thirty-five adult male Wistar rats weighing between 100-196g and 15 mice of the same weight range were included in the study. Lawsonia inermis extracts and aluminum chloride (AlCl) were administered for a period of three weeks to five rats per group.

Histomorphometric evaluation of seminiferous tubules and stereological assessment of germ cells in testes following administration of aqueous leaf-extract of Lawsonia inermis on aluminium-induced oxidative stress in adult Wistar rats.

Objectives: This study aimed to investigate the 'Cytoprotective effect of Lawsonia inermis aqueous leaf-extract on aluminium-induced Oxidative stress in Histomorphometric of the Seminiferous tubule and Stereology of Germ Cells of adult male Wistar rats', assessing its effect on the Histomorphometry of the Seminiferous tubule and Stereology of Germ Cells.

Methods: Thirty-five adult male Wistar rats, weighing between 100-196g, and fifteen mice of the same weight range were used. Lawsonia inermis extracts and aluminum chloride (AlCl) were administered for a period of three (3) weeks, with Five (5) rats per group.

Histomorphology, Sperm Quality and Hormonal Profile in Adult Male Sprague-Dawley Rats following administration of aqueous crude Extract of by gastric gavage.

Objective: The present study focused on histomorphology, sperm quality, hormonal profile and hematological parameters in adult male Sprague-Dawley rats following the administration of aqueous crude extract of by gastric gavage.

Methods: Fourty healthy male adult (12-14 weeks old) Sprague-Dawley rats weighing 200-220g were randomly divided into four groups (A,B,C and D) of ten (n=10) rats each. Group A which served as control were given distilled water 2ml/kg b.
