Mother-infant relationship in the slender loris (Loris tardigradus lydekkerianus)

Close observations under caged conditions were made on the behaviour of four mother lorises towards their own and alien infants. There appears to be no mutual recognition between the mother and her infant, and the relationship appears to be less specific. The infants are accepted by and get settled with any lactating female. In the first few weeks after birth, there is an intense attachment exhibited by the mother towards her baby. When the baby is separated, it exhibits a series of “fixed action patterns.” As the infant grows older, maternal interest declines and is lost after about 15–20 weeks post partum. Vocalization of the separated juveniles evokes greater maternal response than the visual cue

Biochemical profile of Boswellia serrata and Rhus mysorensis

The seasonal variation of proteins and amino acids content have been investigated from leaves, wood and bark of Boswellia serrata and Rhus mysorensis are the medicinal important plant of Laling forest Dhule district of Maharashtra. Comparative account of protein content of leaves, wood and bark of Rhus mysorensis showed higher level (range 1.897 to 2.754 mg/g dry wt.) than Boswellia serrata  (range 1.846 to 2.312 mg/g dry/wt.). Comparative account of amino acid content of leaves, wood and bark of Rhus mysorensis showed higher level (range 0.911 to 1.074 mg/g dry wt.)  than Boswellia serrata  (range 0.745 to 0.896 mg/g dry wt.). Keywords: Protein, amino acid ,  Boswellia serrata and Rhus mysorensi

Parturition in the slender loris (Loris tardigradus lydekkerianus)

The process of the birth of an infant slender loris has been observed under caged conditions-probably for the first time. The total time taken for the complete emergence of the fetus was 4 min and 34 sec. Three hours and 4 min later, the placenta was expelled and was completely devoured by the mother. Both head and breech presentations are normal and involve no manipulation from the mother. Detailed observations have been made on the pre-parturitional and post-parturitional changes in the mother. © 1980 Japan Monkey Centre

Effect of castration and androgen treatment on the androgen dependent parameters in the accessory glands of the slender loris, loris Tardigradus lydekkerianus (Cabra)

The accessory glands of reproduction in slender loris exhibit reduction in secretory activity following castration for 15 days and 30 days. Administration of androgens (testosterone-propionate and 5α dihydrotestosterone) to castrated animals had a differential effect in maintaining the biochemical parameters like citric acid and fructose. © 1985 Indian Academy of Sciences

Biochemical Evaluation of Some Liverworts Pigments and Phenolics

Three genera viz. Riccia, Plagiochasma and Targionia were studied biochemically. It was found that amount of total chlorophylls and polyphenol content is more in Targionia as compared to Riccia and Plagiochasma Flavonoids are also studied adopting chromatography technique and when the spots viewed under UV were found to be of similar type in Riccia, and Plagiochasma, whereas Targionia showed the present of only one spot ,identical to the second spot isolated in Riccia, and Plagiochasma Keywords: Biochemical, Riccia, Plagiochasma, Targionia, pigments, phenolics

Seasonal changes in the adrenal glands of the south Indian female gerbil, Tatera indica cuvierii (Waterhouse) in relation to the reproductive cycle

The adrenal glands of the south Indian female gerbil, Tatera indica cuvierii (Waterhouse) exhibited seasonal changes in their weight, histology and histochemistry during different months of the year. Seasonal changes seen in the adrenal glands also correlate with that of changes in the ovary. The cortical cells of the zona fasiculata and zona reticularis in the adrenal glands of sexually active gerbils show decrease in cell as well as nuclear sizes during quiescent period (April-July). The zona glomerulosa and medulla do not show any changes in their structure during different reproductive phases. Histochemically, the zona fasiculata and zona reticularis of the adrenal glands of the gerbils accumulate abundant lipids and carbohydrates during breeding period, when compared with quiescent females. The 'X' zone shows fluctuation and is present in the mature, pregnant and spayed females and disappears in parous and quiescent gerbils. It is inferred that a relatively unchanged secretion of mineralocorticoids, an increased or decreased secretion of glucocorticoids required to maintain the functional status of adrenal cortex could be possible in gerbils during the reproductive cycle. © 1988 Indian Academy of Sciences
