Purpose
The spleen is relevant in blood purification, hematopoiesis, metabolism, and
immune response to antigens, in addition to the storage and control on the
release of metals and amino acids. Its functions concerning reproduction
characteristics are still unknown. The objective was to study the influence
of splenectomies on reproduction.
Methods
This study analyzed 25 mice couples, distributed into five groups: group 1 –
control, no surgery: group 2 – control, submitted to laparotomy and
laparorrhaphy only; group 3 – splenectomy in male mice; group 4 –
splenectomy in female mice; group 5 – splenectomy in male and female mice.
The animals were studied as regards the number of gestations and offspring
generated in each gestation.
Results
A decrease in both the number of gestations and the number of offspring was
verified in the male mice that had received a splenectomy when coupled with
normal female mice. It is important to emphasize lower reproduction level
when paired asplenic males with normal females, otherwise, the couples in
which both mice had been splenectomized did not present change in the
reproduction pattern.
Conclusions
A reduction in the number of pregnancies and litters occurs in mice couples
when the male mice were previously splenectomized.
Conflict of interest: none Introduction: traffic accidents are one of the main causes of death and disability, with motorcyclists representing the great majority of both the victims and the perpetrators. Objective: this work studied the characteristics of motorcyclists injured in accidents involving motorcycles and automobiles. Method: this study sought to interview 100 motorcyclists who had been injured in collisions between motorcycles and automobiles, and who were undergoing emergency hospital treatment in the region of Belo Horizonte, Brazil. The questionnaires included demographic information (age, gender, skin color, education level, profession) and questions about years of licensed driving practice, how often they would drive an automobile, how long they had had a motorcycle driver's license, how often they would ride a motorcycle, the number of prior accidents involving a car, and the number of prior accidents not involving a car. Results: of the 100 consecutive accidents studied, 91 occurred with men and 9 with women, aged between 16 and 79 (m = 29 ± 11) years. Regarding their reason for using a motorcycle, 83% reported using it for transport, 7% for work, and 10% for leisure. Most of these accident victims had secondary or higher education (47%). Of the motorcyclists who held a car driver's license, 68.3% drove the vehicle daily or weekly and held the license for more than one year. Sixty-seven percent of the accident victims used a motorcycle daily and had a motorcycle driver's license for at least one year. Conclusion: among the motorcyclists injured, most were men aged 20 years or older, with complete secondary education, and experienced in driving both motorcycles and cars, indicating that recklessness while driving the motorcycle is the main cause of traffic accidents.
O queijo Minas Frescal representa a maioria dos queijos comercializados em feiras e mercearias em consequência do alto rendimento na fabricação e preço acessível à população. Diante disso, o objetivo com este trabalho foi avaliar as características físico-químicas deste queijo comercializado em feiras livres na cidade de Montes Claros, Norte de Minas Gerais. Após a coleta de queijos em cinco diferentes feiras, foram avaliadas as características referentes ao pH, acidez, umidade, proteína e gordura. Observou-se falta de padronização na produção associada a variação nos teores de umidade (32,62 a 54,06%), proteínas (34,21 a 49,43%) e gordura no extrato seco (41,30 a 58,41%). Em relação aos valores de pH e acidez dos produtos, a temperatura de armazenamento pode torná-los mais ácidos em consequência do tempo de exposição nos locais de venda. Conclui-se que a aplicação de procedimentos operacionais e tecnológicos adequados pode melhorar a qualidade dos produtos, cuja maior procedência é artesanal.
