Purpose: The present study was designed to explore the effect of intraperitoneal administration of cisplatin in germinal epithelium of mice. There are few reports on the side effect of cisplatin on spermatogenesis when are used as anticancer drug. Therefore, in the present study the effect of cisplatin on spermatogenesis was evaluated by electron microscopy.
Methods: Twenty balb/c mice aging 6-8 weeks was used in this study. The mice were divided into two groups, control and cysplatin treated. cysplatin was injected for five days as 2.5 mg /kg. The mice were sacrificed after 5 weeks and testicular specimens were removed, fixed in boueins, formaldeyd fixative and 2.5% Glutaraldehide then prepared for light and electron microscopic study.
Results: Observation with optic microscope in treated group thickness of germinal epithelium was reduced a lot and increased the number of apoptotic cells. In some seminiferous tubules only sertoli cells were observed and nucleus of spermatogony cells was hetrochromatin. The electron microscopic observations showed some irregularity waviness and thickening in basal layer. Also myoid cells of this group were thick and contracted. In this group many apoptotic cells and damaged organelles were seen.
Conclusion: It was indicated that cisplatin affected testicular germinal epithelium by both cytotoxic effect and induction of apoptosis.

Unlabelled: The tonsils have been identified as a site of replication for Epstein-Barr virus, adenovirus, human papillomavirus, and other respiratory viruses. Human tonsil epithelial cells (HTECs) are a heterogeneous group of actively differentiating cells. Here, we investigated the cellular features and susceptibility of differentiated HTECs to specific influenza viruses, including expression of avian-type and mammalian-type sialic acid (SA) receptors, viral replication dynamics, and the associated cytokine secretion profiles.

Infertility can harm a patient in physical, psychological, spiritual, and medical ways. This illness is unusual because it affects the patient's companion and the patient individually. Infertility is a multifactorial disease, and various etiological factors like infection are known to develop this disorder.

Scientific bodies overseeing UV radiation protection recommend safety limits for exposure to ultraviolet radiation in the workplace based on published peer-reviewed data. To support this goal, a 3D model of the human cornea was used to assess the wavelength dependence of corneal damage induced by UV-C radiation. In the first set of experiments the models were exposed with or without simulated tears; at each wavelength (215-255 nm) cells with DNA dimers and their distribution within the epithelium were measured.

Complexity and reproductive plasticity are very well-known characteristics of anurans. The group is being continuously explored taxonomically and phylogenetically, which leads to a great potential diversity not yet uncovered. This is particularly evident due to the lack of investigation regarding species-specific traits, even the ones well distributed in the lineages as polyandry.
