RESUMEN

The consumption of alcohol by people living with HIV/AIDS is associated with a graver prognosis. Long-term use of antiretrovirals may have certain health challenges that may be aggravated by concomitant alcohol use. This study investigated virgin coconut oil (VCO) as an adjuvant to the deleterious effects of highly active antiretroviral therapy (HAART) and alcohol on the cyto-architecture and functioning of the testis. Forty adult male Sprague-Dawley rats, weighing 165~176 g, were divided into eight groups and treated according to protocol. Testicular histology, stereological parameters, seminal fluid, testosterone, luteinizing hormone, follicle-stimulating hormone, the antioxidants marker malondialdehyde (MDA), and antioxidant glutathione (GSH) were examined. The use of ethanol alone and ethanol + HAART showed extensive degeneration in the seminiferous epithelium, decreased semen quality, disorganized basement membrane and widened, hypocellular interstitium. GSH was significantly decreased in the ethanol alone treated group with no significant effect on testosterone, LH, and MDA levels. Adjuvant treatment with VCO at low dose (2.5 mL/kg/bw) improved sperm motility with a partial restoration of the histopathological alterations. High doses of VCO (5.0 mL/kg/bw) showed greater improvement with respect to sperm counts, increased FSH hormonal and GSH antioxidant levels, and a well-preserved testicular cyto-architecture.

RESUMEN

The effects of Virgin coconut oil as an adjuvant to highly active antiretroviral therapy (HAART) were investigated on the testicular ultrastructure and biochemical markers in rats. Twenty male Sprague-Dawley rats, weighing 153-169 g were divided into four groups and treated as follows: control A (distilled water), B (HAART), C (HAART+Virgin coconut oil 10 ml/kg) and D (Virgin coconut oil [VCO] 10 ml/kg). Testicular segments were evaluated using transmission electron microscopy. Serum was assayed for testosterone, luteinising hormone, follicle stimulating hormone and testicular tissue for malondialdehyde and glutathione. Ultrastructure of basement membrane (Bm), mitochondria and spermatocytes was normal in the control group. HAART-treated group showed significant increase (p < .01) in Bm thickness with significant decrease in Leydig cell nuclear diameter (p < .05) and volume (p < .01) when compared with control group. Mitochondrial cristae appear collapsed, and Sertoli cells showed cytoplasmic vacuolations. HAART+VCO group showed improved ultrastructural details in Bm, and Sertoli cell and Leydig cells show abundant lipid droplets. Virgin coconut oil-treated group showed thinning of Bm with otherwise normal ultrastructural features of organelles. HAART-treated group showed significant increase (p < .01) in testosterone levels. There was no significant effect on malondialdehyde and glutathione levels. Virgin coconut oil improved testicular morphology and reversed HAART-induced ultrastructural alterations. Further studies on putative mechanism are required.

RESUMEN

Although the successful introduction and rollout of antiretroviral therapy has impacted positively on morbidity and mortality of HIV-positive patients, its interaction with plant-based adjuvants remain sparsely investigated. We report the interaction and effects of adjuvant treatment with highly active antiretroviral therapy (HAART) and Hypoxis hemeocallidea (HH) extracts on testicular structure of rats. A total of 63 pathogen-free adult male Sprague Dawley rats were divided into nine groups and treated according to protocols. HAART cocktail predisposed to significant negative testicular parameters of sperm count, motility and seminiferous tubular epithelial height (quantitatively) (p < .03) and also altered the histomorphology of tubules with diffuse hypoplasia in seminiferous tubules. The higher dose of HH showed a better ability to mitigate the altered parameters and compares favourably with vitamin C in this protocol. While HH did not show any deleterious impact on morphometric data, its role as adjuvant did not significantly reduce the negative impact of HAART on morphometric indices especially with the lower dosage. Further investigations are warranted on the interactions between HAART and Hypoxis.

RESUMEN

To study the protective effect of Red Palm Oil (RPO) on testicular damage induced by administration of lead acetate on male Sprague-Dawley rats, 28 rats divided into four groups of 7 animals each were used. They were administered orally with RPO (1 mL and 2 mL) and lead acetate (i.p.) 6 mg/kg body weight/day, respectively. Treatment was conducted for 8 weeks, and 24 hrs after the last treatment the rats were sacrificed using cervical dislocation. Sperms collected from epididymis were used for seminal fluid analyses; while the testes sample was used for ROS and oxidative enzyme activities assessment. Statistical analysis was carried out using GraphPad Prism 5.02 statistical analysis package. Administration of lead acetate increased generation of reactive oxygen species (ROS) significantly (p < 0.05) as evidenced by the elevated value of H2O2 and LPO and decreased GSH level. Also there was reduced epididymal sperm count, poor grade of sperm motility, and lower percentage of normal sperm morphology significantly. Coadministration with RPO, however, has a protective effect against lead toxicity by decreasing H2O2 production, increased GSH level, and increased sperm qualities especially. This shows that RPO has a potential to attenuate the toxic effect of lead on testicular cells preventing possible resultant male infertility.
