Assessing the effectiveness of 30% sodium chloride aqueous solution for the preservation of fixed anatomical specimens: a 5-year follow-up study

Anatomical specimens used in human or veterinary anatomy laboratories are usually prepared with formaldehyde (a cancerous and teratogenic substance), glycerin (an expensive and viscous fluid), or ethanol (which is flammable). This research aimed to verify the viability of an aqueous 30% sodium chloride solution for preservation of anatomical specimens previously fixed with formaldehyde. Anatomical specimens of ruminant, carnivorous, equine, swine and birds were used. All were previously fixed with an aqueous 20% formaldehyde solution and held for 7days in a 10% aqueous solution of the same active ingredient. During the first phase of the experiment, small specimens of animal tissue previously fixed in formaldehyde were distributed in vials with different concentrations of formaldehyde, with or without 30% sodium chloride solution, a group containing only 30% sodium chloride, and a control group containing only water. During this phase, no contamination was observed in any specimen containing 30% sodium chloride solution, whether alone or in combination with different concentrations of formaldehyde. In the second phase of the experiment, the 30% sodium chloride solution, found to be optimal in the first phase of the experiment, was tested for its long-term preservation properties. For a period of 5years, the preserved specimens were evaluated three times a week for visual contamination, odors, and changes in color and texture. There was no visual contamination or decay found in any specimen. Furthermore, no strange odors, or changes in color or softness were noted. The 30% sodium chloride solution was determined to be effective in the preservation of anatomic specimens previously fixed in formaldehyde.

Double-Blind clinical study of a multivitamin and polymineral complex associated with Panax ginseng (Gerovital)

The present study aimed to evaluate the efficacy of a multivitamin and poly minerals supplemented with Panax ginseng extract (Gerovital®) on patients suffering from common physical or mental stress. The study design was controlled, parallel and double blind. Patients were randomly divided in two groups and underwent a thorough clinical and laboratory examination. Group A received placebo capsules and group B received Gerovital® capsules. In both cases, two capsules were taken daily during meals for eight weeks. Mood as well as physical activity were evaluated through a questionnaire assessing quality of life. From the 126 patients enrolled, 12 patients (8 in group A and 4 in group B) were excluded due to voluntary withdrawal, 55 patients completed the study in group A and 59 in group B. The treatment with Gerovital® significantly increased the quality of life when compared to placebo. After 15 days of study no difference between groups was observed. However, at 30th, 45th and 60th day, group B showed a statistically significant increase in average score from 30.05 to 41.96, 47.01 and finally 50.81 points. No increase in body weight was detected in either group. No difference in blood pressure or heart rate was also observed between treatments. The present study has shown that the daily use of Gerovital® over a 2-month period can be effective in improving quality of life in patients suffering from physical and mental stress among individuals of different ages, ranging from adults to elderly. Moreover, its use has been associated to a lower incidence of flu-like seasonal respiratory illnesses. Finally, the incidence of undesired effects was similar to placebo.

Model to estimate lysine requirements of broilers

The purpose of this study is to describe the development of a model to predict the digestible lysine requirements of broilers using the factorial approach, and to evaluate the model using as reference the model presented in Brazilian Tables for Poultry and Swine. The model partitions the requirement for maintenance and growth for feather-free body protein and feather protein, in which the inputs are body and feather protein weight and the daily rates of protein deposition in the feather-free body and feathers. The parameters that express the lysine requirement for maintenance were obtained in metabolism trials with roosters, and those for the efficiency of lysine utilization in experiments with broilers from 1 to 42 d. Based on these results the model proposed was: Lys (mg/d) = [(151xBP(m)(-0.27)xBP(t)) + (0.01xP(t)x18)] + [(75xBPD/0.77) + (18xFPD/0.77)], where Lys = digestible lysine requirement (mg/d), BPm=body protein weight at maturity (kg), BPt=body protein weight at time t (kg), FPt=feather protein weight at time t (kg), BPD=body protein deposition (g/d), FPD = feather protein deposition (g/d). The model yields sensible predictions of the digestible lysine requirements of broilers of different strains and ages growing at their potential, and suggests a lower lysine requirement after 27 d than does the Brazilian model. The proposed model is the first step in the development of a simulation model that predicts the food intake of a broiler and hence the dietary amino acid content that would optimise performance.

Probiótico em dietas de suínos sobre os parâmetros sanguíneos e digestibilidade de rações

Two assays were accomplished being, both using a randomized block design: Assay 1 the aimed was to evaluate the blood parameters of weaned recently pigs and receiving rations with and without probiotic. Twenty pigs with body weight of 6.99 +/- 0.42 kg were used and were collected samples of blood to the 0, 7, 14, 21 and 28 days after wean, for determinations of the bool parameters. Assay 2 the objective was to determine the rations digestibility for growth swine supplemented or not with probiotic in the rations. The rations and the ages of the animals influenced most of the variables of the blood parameters. The probiotic didn't alter the ration digestibility to exception for mineral matter. It is ended that the blood parameters were altered for the use of the probiotic and the age of the animals, both emphasized to challenges happened after wean and the mineral matter was better taken advantage with the use of the probiotic.

Oocyte maturation in bitches

The canine species has been used as an experimental model for preservation of endangered species. Biotechnologies of reproduction, such as in vitro maturation (IVM), have been used to meet this objective. Several protocols for in vitro embryo production (IVEP) in swine and bovine species have been adapted for canids. However, the highest rate reported for in vitro maturation in canids is only 39%, which is still lower than those in other species. Therefore, current research on assisted reproduction in canids have focused on several IVM protocols, including the addition of proteins, hormones, meiosis inhibitors, growth factors and antioxidants to the maturation media and the determination of suitable timing for culture, so that variables involved in the process can be fine-tuned. This review has the main objective of describing major developments and limitations in the process of oocyte maturation in bitches.
