[Pseudotumoral sublingual leishmaniasis caused by Leishmaniainfantum]. / Leishmaniose sublinguale pseudotumorale à Leishmaniainfantum.

INTRODUCTION: Mucosal leishmaniasis is endemic in certain parts of Latin America and are usually absent in Morocco. Herein we report a case of Leishmaniainfantum in a Moroccan patient. PATIENTS AND METHODS: A 61-year-old male patient working as a tourist bus driver presented with a sublingual endobuccal tumor. He reported a history of treated cutaneous leishmaniasis of the lower lip in 2009 and had presented the sublingual oral tumor since December 2011. The histopathological findings as well as the species-specific PCR analysis confirmed the diagnosis of sublingual mucosal leishmaniasis due to L. infantum. HIV serology was negative. Our patient was then treated with intra-muscular meglumine antimoniate for 25 days, resulting in complete disappearance of the oral lesion. CONCLUSION: Our case thus has several peculiarities: the strictly mucosal character of the lesion, occurring in an immunocompetent subject, the unusual pseudotumoral form, and the causative agent, L. infantum, not known for its mucosal tropism in our country.

Resveratrol reverses cadmium chloride-induced testicular damage and subfertility by downregulating p53 and Bax and upregulating gonadotropins and Bcl-2 gene expression.

This study was performed to investigate the protective and therapeutic effects of resveratrol (RES) against CdCl2-induced toxicity in rat testes. Seven experimental groups of adult male rats were formulated as follows: A) controls+NS, B) control+vehicle (saline solution of hydroxypropyl cyclodextrin), C) RES treated, D) CdCl2+NS, E) CdCl2+vehicle, F) RES followed by CdCl2 and M) CdCl2 followed by RES. At the end of the protocol, serum levels of FSH, LH and testosterone were measured in all groups, and testicular levels of TBARS and superoxide dismutase (SOD) activity were measured. Epididymal semen analysis was performed, and testicular expression of Bcl-2, p53 and Bax was assessed by RT-PCR. Also, histopathological changes of the testes were examined microscopically. Administration of RES before or after cadmium chloride in rats improved semen parameters including count, motility, daily sperm production and morphology, increased serum concentrations of gonadotropins and testosterone, decreased testicular lipid peroxidation and increased SOD activity. RES not only attenuated cadmium chloride-induced testicular histopathology but was also able to protect against the onset of cadmium chloride testicular toxicity. Cadmium chloride downregulated the anti-apoptotic gene Bcl2 and upregulated the expression of pro-apoptotic genes p53 and Bax. Resveratrol protected against and partially reversed cadmium chloride testicular toxicity via upregulation of Bcl2 and downregulation of p53 and Bax gene expression. The antioxidant activity of RES protects against cadmium chloride testicular toxicity and partially reverses its effect via upregulation of BCl2 and downregulation of p53 and Bax expression.
