Morphologic comparison between fetal uterus and adult uterus in the alpaca (Vicugna pacos) and the llama (Lama glama) RESUMEN Objetivos: Comparar los aspectos morfológicos del tracto genital fetal y adulto de la alpaca y la llama. Material y métodos: se realizó el estudio anatómico del útero de cinco fetos de llama y cinco fetos de alpaca, ambos de tercer tercio de gestación, once úteros de alpacas adultas y cinco úteros de llamasadultas. Las muestras de útero se estudiaron por observación anatómica y morfometría. Resultados: Mediante los estudios morfométricos se pudo observar que existía diferencia significativa en el tamaño de ambos cuernos uterinosa favor del lado izquierdo. La relación existente entre el cuerno uterino derecho y el cuerno uterino izquierdo en la alpaca adulta es de 0,79 y en la llama adulta la razón de las medidas es mayor, 0,85 para la longitud y 0,87 para el ancho. En los úteros fetales tanto en llama como en alpaca, se observó que existía diferencia significativa entre el tamaño del cuerno uterino izquierdo y el cuerno uterino derecho a favor del lado izquierdo. Conclusiones:Se concluye que existe similitud entre la forma del útero en los fetos de llama y alpaca en relación al útero de la correspondiente hembra adulta. SUMMARY Objectives: Made a morphologic comparison between fetal uterus and adult uterus in the alpaca and the llama. Material and methods: it was performed anatomical study of five fetal uteri of lama and alpaca, eleven adult alpacas and five lamas uteri. Uterus samples were studied by anatomical observation and morphometry. Results: The results showed that all the samples of adult females had greater development of the left uterine horn. By morphometric studies it was observed that there was significant difference between the size of both uterine horns. The relationship between the right uterine horn and left uterine horn in the alpaca is 0.79 and in the lama, the ratio of the measures is higher, 0.85 for length and 0.87 to the width, in favor of the left uterine horn. In both fetal uterus in the lama as alpaca, was observed that there was significant difference between the size of the left uterine horn and the right uterine horn. Conclusions: exits similarity between the shape of the uterus in the lama and alpaca fetuses in relation to the uterus of the corresponding adult female.

I . Total skinfold thicknesses (sum of seven sites) were measured in fifty-seven pregnant women with low energy and protein intake, at weeks 24,30 and 35 of gestation.2 . Women were classified in two groups (overweight and low weight), according to their weight-forheight at week 24 of gestation.3. Half of the women did not increase, or even reduced the amount of subcutaneous fat during the observation period. The lowest mean value of total skinfold thickness was found in the low-weight women who showed a reduction of the subcutaneous fat.4. This finding shows that a significant proportion of malnourished women do not follow the average pattern of subcutaneous fat accumulation seen in healthy pregnant women without food intake restriction, during the second half of pregnancy.It has been reported that the average healthy pregnant woman, without food intake restriction, deposits a fair amount of subcutaneous fat between weeks 10 and 30 of gestation and this deposition, which is greater in primiparae and in women with low initial weight, slows down after this time (Taggart, Holliday, Billewicz, Hytten 8t Thomson, 1967). However, it is not known if pregnant women from populations with a high prevalence of energy-protein malnutrition and restricted food intake show the same pattern.The present work aims to describe the magnitude and variability of the subcutaneous fat deposition during the second half of pregnacy in such a group of women of rural and urban origin.
