Caecilians, of the order Gymnophiona in the Lissamphibia, are circumtropically distributed across most moist tropical regions of the world. Gymnophiona are among the least understood terrestrial vertebrates and have received lesser attention than the other two orders of lissamphibians, the Urodela and Anura. Spermiogenesis, known as spermateleosis in lower vertebrates, is the transformation of the round spermatid into a highly specialized spermatozoon with a species-specific structure. Spermateleosis and sperm morphology of two species of caecilians, Ichthyophis tricolor and Uraeotyphlus cf. narayani, from the Western Ghats of Kerala, India, were studied using light and scanning electron microscopy. The cyst morphology is described in ten steps. We also report the sperm transporting course in this enigmatic amphibian in addition to localizing sperm in the kidney. This confirms the transport of sperm through the kidney.Keywords

Quassia amara is a medicinal plant with several pharmacological properties. More recently, it has come to be known in the context of its potential biopesticidal application and the antimalarial property in two of its secondary metabolites, quassin and neo-quassin. There are also preliminary reports implicating this plant in male reproductive toxic effects, to the extent that the plant could as well be tested for male contraceptive efficacy. Therfore, we subjected the methanolic extract of the bark of this tree for male reproductive toxicological evaluation. This paper reports several derangements in the Cauda epididymidal sperm including a hither - to unreported one.Keywords

Quassia amara is a Brazilian medicinal plant traditionally used as an herbal remedy for a variety of diseases. Quassin is the major secondary chemical compound in it, which is under investigation as an anti-malarial compound. There are preliminary studies implicating Q. amara in male reproductive toxicity. Hence, this elaborate study was undertaken to find the male reproductive toxic effects of Q. amara and quassin. Methanolic extract of Q. amara bark and quassin were administered to male mice for 35 days. The cauda epididymidal sperm, testis and epididymis were subjected to analysis adopting light and transmission electron microscopy. Sperm counts, motility and viability decreased. The incidence of sperm with abnormal morphologies increased. There was premature loss of germ cells from the seminiferous tubules, which correlated with Sertoli cell pathology. The Leydig cells were vacuolated, suggesting a hypo-androgen status. The epididymis indicated severe histopathological changes, including reflection of a mitogenic/tumorigenic effect of Q. amara. Thus, this study indicates that Q. amara, when applied as a therapeutic, could be severely toxic to male reproductive mechanisms and the principal mechanism of action appears to be through Leydig cells. Quassin, the major secondary metabolite responsible for the therapeutic potential of Q. amara, is also the one causative of the male reproductive toxic effects. Thus, this study substantiates the claim that Q. amara is toxic to male reproductive system.Keywords
