Cabbage juice protect against lead-induced liver and kidney damage in male Wistar rat.

AIM: Liver and kidney has been implicated in Lead toxicity and this has been linked to oxidative damage. On the other hand, cabbage is one of the widely consumed vegetables with a plethora of health benefits. This present study investigated the protective effect of cabbage juice on lead-induced toxicity in male Wistar rats. METHODS: Twenty male Wistar rats were randomly divided into four groups (n = 5) and were treated with distilled water (1 ml/100 g b.wt), Lead acetate (25 mg/kg b.wt), cabbage juice (1 ml/100 g b.wt) and Lead acetate plus cabbage juice respectively. All treatments were administered orally for 28 days. Following euthanasia, blood was collected and serum decanted for biochemical assay and liver and kidney tissues were harvested, prepared for antioxidant activity and histological study. RESULT: Cabbage juice significantly attenuated Lead-induced liver and kidney dysfunction by lowering serum concentrations of urea, creatinine, ALP, AST and ALT. Antioxidants (SOD, CAT, GSH) were also upregulated in liver and kidney tissues. Cabbage juice restored the histoarchitectural changes caused by lead intoxication. CONCLUSION: Cabbage juice consumption protected the liver and kidney against lead-induced toxicity by enhancing in vivo anti-oxidant defense system.

In Vivo Attenuation of Alcohol- and Cadmium Chloride-Induced Testicular Toxicity Modulated by Silymarin in Male Wistar Rat.

The aim of the study is to investigate the in vivo attenuation of alcohol- and cadmium chloride-induced testicular toxicity modulated by Silymarin in male Wistar rats. A total of fifty-six (56) Wistar rats were used for this study and they were randomized into seven (7) groups of eight (8) rats each. Group 1 was control rats; Groups 2-7 served as the experimental groups. After 6 weeks treatment duration, the rats were euthanized, semen was collected for semen analysis, blood samples for testosterone, and FSH and LH assay determination, and left testes was harvested for histological analysis. One-way ANOVA was used to compare means at p-level < 0.05 was considered significant. Findings from this study have shown that alcohol and cadmium chloride adversely affected semen parameters, testosterone, and FSH and LH hormone milieu. Data also showed that Silymarin administration attenuated the adverse effect of alcohol and cadmium chloride on semen quality and hormones associated with reproductive functions. Hence, Silymarin mopped the effect of in vivo attenuation of alcohol and cadmium chloride testicular damage. The findings of this study have further established that alcohol and cadmium chloride adversely affected semen parameters, testicular alterations, and serum hormonal milieu. However, the effect was more significantly deleterious in rats exposed to cadmium chloride when compared to rats exposed to alcohol, subsequently alcohol- and cadmium chloride-induced degeneration of testicular tissues. Furthermore, Silymarin administration attenuated the adverse effect of alcohol on semen quality and hormones associated with reproductive functions.

Down regulatory response of reproductive potentials in stress-induced rats supplemented with clomifene citrate: The fate of infertility.

This study was designed to physiologically investigate the fate of stress related infertility conditions to focus on the regulatory response of reproductive potentials in stress-induced female Wistar rats supplemented with clomifene citrate. 42 apparently healthy female Wistar rats weighing about 120-160 g were used in the study. The animals were randomly distributed into 3 groups after acclimatization for 2 weeks. Group 1 served as the control pregnant rats not induced by restraint, mirrored and intruder stressors, group 2 consisted of rats treated with 0.013 mg/g of clomifene citrate drug and exposed to three different stressors while group 3 represented pregnant rats exposed to different stressors but not treated with clomifene citrate. At the end of 3weeks, the rats were euthanized via cervical dislocation. The uterus and ovary organs were carefully isolated, weighed and examined for histological changes. The reproductive capacities studied were gestation period, mean pup weight, litter size and survival rate respectively. Data collected is expressed in Mean±SEM and one way ANOVA statistics was used for comparison of means while Fisher's LSD was employed for post hoc test and the level of significance is determined at p-value < 0.05. Results from our study revealed that restraint and intruder stressors following supplementation with clomifene citrate produced similar stress response in the gestation length, pub-weights, litter size and percentage of survival. Stress of different nature altered the histoarchitecture of the ovary and the uteri of rats exposed to restraint or intruder stressor. Meanwhile, Clomifene citrate administration produced effect on ovulation and pregnancy outcome of stressed pregnant rats and the survival ratio of the offspring.
