Roe deer are seasonal breeders with a complete yearly testicular cycle. The peak in reproductive activity is recorded during summer, the rutting period, with the highest levels of androgens and testicular weight. Melatonin plays a pivotal role in seasonal breeders by stimulating the hypothalamus–pituitary–gonads axis and acting locally; in different species, its synthesis within testes has been reported. The aim of this study was to evaluate the physiological melatonin pattern within roe deer testes by comparing data obtained from animals sampled during pre- and post-rut periods. Melatonin was quantified in testicular parenchyma, along with the genetic expression of enzymes involved in its local synthesis (AANAT and ASMT) and function (UCP1). Melatonin receptors, MT1-2, were quantified both at protein and gene expression levels. Finally, to assess changes in reproductive hormonal profiles, testicular dehydroepiandrosterone (DHEA) was quantified and used for a correlation analysis. Melatonin and AANAT were detected in all samples, without significant differences between pre- and post-rut periods. Despite DHEA levels confirming testicular involution during the post-rut period, no correlations appeared between such involution and melatonin pathways. This study represents the first report regarding melatonin synthesis in roe deer testes, opening the way for future prospective studies in the physiology of this species.

The middle ear fluids of seven patients with bilateral, and five patients with unilateral serous otitis media (SOM), were demonstrated to be microbiologically sterile when assessed for the presence of bacteria, mycoplasma, viruses, and fungi. The concentrations of immunoglobulins G, M, A, D, and lysozyme (muramidase) were determined in the serum and middle ear fluids. Lysozyme levels of middle ear aspirates were found to be elevated in SOM patients. The elevated levels of lysozyme in combination with the antibody-containing classes of immunoglobulins may explain the microbiologically sterile condition of the middle ear fluids of SOM patients. Also, the elevated lysozyme concentrations in middle ear fluids may indicate the previous presence of neutrophils and hence a previous inflammatory insult. The increased levels of IgA demonstrated in middle ear fluids may indicate local synthesis of secretory IgA by secretory cells of Eustachian tube and middle ear. The closed Eustachian tube, partial vacuum conditions and absence of a portal of exit for accumulated serous fluids are offered as a possible explanation for SOM.

1. The specific radioactivity of [14C]cholesterol in plasma and in serial biopsies of muscle and skin was measured in Rhesus monkeys for 156 days after a single intravenous injection of [14C]cholesterol. 2. Analysis of the specific radioactivity—time curves in terms of a two-compartment system indicated that all the cholesterol of muscle is exchangeable with the plasma cholesterol and that local synthesis does not contribute significantly to the cholesterol in muscle. 3. Analysis of the curve for specific radioactivity of skin cholesterol suggested the presence of a small pool of cholesterol with slow turnover. A contribution to skin cholesterol from local synthesis could not be excluded.
