Melatonin blocks dexamethasone-induced immunosuppression in a seasonally breeding rodent Indian palm squirrel, Funambulus pennanti.
In vivo effect of dexamethasone and melatonin on immunomodulation has been investigated by studying the lymphocyte proliferation to the mitogen Con A from various lymphoid tissues including bone marrow cells of a seasonally breeding rodent adult male F. pennanti during reproductively inactive phase (October to December). During this phase, animal faces the maximum challenges of the nature (hypo...
متن کاملVariation in gonadal steroid and melatonin during gestation of a diurnal seasonal breeder Indian palm squirrel Funambulus pennanti
Very little information is available to delineate the role of melatonin during the complex process of gestation in seasonally breeding mammals. The present study was aimed at understanding the physiology of gestation and fetal growth in relation to maternal hormonal levels, including melatonin, of a tropical seasonal breeder, Funambulus pennanti. Through assessment of the vaginal smear during b...
متن کاملPhotoperiod-testicular-immune interaction in a seasonal breeder Indian palm squirrel Funambulus pennanti during the reproductively inactive and active phases.
The differential effect of long (LD; 16 : 8 h light/dark), short (SD; 10 : 14 h light/dark) and natural day length (NDL; 12 : 12 h light/dark) during the reproductively inactive (RIP) and active (RAP) phases was assessed in relation to immunity and reproductive function of a tropical rodent Funambulus pennanti. They presented high immunity and low testicular activity during RIP and an opposite ...
متن کاملProfile of organ weights and plasma concentrations of melatonin, estradiol and progesterone during gestation and post-parturition periods in female Indian palm squirrel Funambulus pennanti.
Todate, report about the role of pineal gland in maintaining the normal physiology of gestation is scanty. Present study is the first of its kind giving a detail profile of organ weights and plasma concentration of melatonin, estradiol and progesterone to suggest a possible role of pineal gland in maintaining normal physiology during gestation and post-parturition periods of female Indian palm ...
متن کاملAge-Dependent Variation in Hormonal Concentration and Biochemical Constituents in Blood Plasma of Indian Native Fowl
This experiment was to investigate the age-related changes in hormonal concentration and biochemical constituents of blood plasma in Indian native desi fowl. One hundred and sixty two (54 from each breed, i.e., Kadaknath (KN), Aseel peela (AP), and White leghorn (WLH)) day-old female chicks were randomly divided into nine groups each of 18 chicks (3 groups × 3 replicates). WLH was taken in this...
