Milk composition in the plains viscacha (Lagostomus maximus).
Milk samples were taken from 10 plains viscacha between 9 and 64 days post partum. Mean concentrations (+/- s.e.) were 17 +/- 1.1 mM-Na; 32 +/- 1.6 mM-K; 35 +/- 2.2 mM-Cl; 116 +/- 3.3 mM-lactose (total reducing sugar) (all in 8 samples); less than 10-220 mg citrate/l (range of 4 samples); 15.7 +/- 0.64 g total nitrogen/l (3 samples). The Na:K ratio was 1:1.95 +/- 0.17. It was estimated that the...
متن کاملCHANGES IN WEIGHT AND HIDROXYINDOLE-O- METHYLTRANSFERASE ACTIVITY OF PINEAL GLAND OF THE PLAINS VISCACHA (Lagostomus maximus maximus)
Seasonal changes in body weight, pineal hydroxyindole-O-methyltransferase activity (HIOMT) and pineal gland weight were analysed for adult male viscacha (Lagostomus maximus maximus). The viscacha is a nocturnal rodent restricted to the Argentinian pampas which lives in large colonies in extensive burrow systems. Animals were captured monthly, at night, near their burrows, in the vicinity of San...
متن کاملPigmented Cells in the Pineal Gland of Female Viscacha (Lagostomus maximus maximus): A Histochemical and Ultrastructural Study
The presence of pigment has been demonstrated in different nervous structures such as those of retina, substantia nigra, and locus coeruleus. These pigments have also been described in the pineal gland of different mammal species. Histochemical and ultrastructural studies of the pineal gland of female viscacha (Lagostomus maximus maximus) were performed to analyze the presence of pigmented cell...

متن کاملProbable effect of photoperiod on seasonal variation in the nuclear volume of the adrenal cortex of viscacha (Lagostomus maximus maximus).
The neuroendocrine system regulates several organic functions such as reproduction, metabolism and adaptation to the environment. This system shows seasonal changes linked to the environment. The experimental model used in the present study was Lagostomus maximus maximus (viscacha). The reproduction of males of this species is photoperiod dependent. Twenty-four adult male viscachas were capture...
